Description

Mask with LV structure

Technical Field

The utility model relates to the technical field of masks, or to the technical field of protective articles or medical care, in particular to a mask with an LV structure.

Background

The existing protective mask is provided with nose bridge strips, three parts of the existing mask are reduced into two parts, and the structure of the existing mask body is not changed, so that a plurality of problems are involved once the structure is changed, and the problems are troublesome, including production. Including machine equipment. The structure of the mask body can not be changed, and the mask is suitable for mass production. As existing sheeters can be utilized. Thus truly realizing the mask with two parts instead of three parts on the basis of the existing industry. The mask is suitable for high-speed production in the high-speed mask industry, is structurally the simplest, and uses the least materials.

The invention has the advantages that the important part of the nose bridge strip is omitted, the nose bridge strip needs to use the steel wire, the resin is also coated outside the steel wire, the steel wire can rust, and the cost of warehouse management can be increased.

Production equipment aspect: the equipment capable of producing the mask can produce the mask with the sliding fixed point, and the production equipment for producing the mask at high speed is not available at present after various schemes fail. The invention discloses innovative structures of some production equipment.

The existing mask consists of: the mask body, the nose bridge strip and the fixing band. In the case of wearing the mask used by most people in the market at present, the condition of air leakage exists, that is, the air exhaled by the people or the outside air can leak out or leak in through the periphery of the mask. The simplest test is that the user exhales towards the mask when wearing the mask, and the user can perceive the mask from the periphery. Even the speaking activity of the N95 mask can move or leak.

Disclosure of Invention

Aiming at the defects existing in the prior art, the utility model aims to provide the mask with the LV structure, which is used as a new mask, and the technical effect is achieved by adopting small changes as far as possible.

The technical scheme of the utility model is realized as follows: make full use of various mechanics, optional: from figures 1,2, the structure of "L" and "V" can be seen, along with their mechanics. A section of straight mask rope is bent into L shape, and the effect of productivity is achieved.

The utility model is simply called V-shaped structure and V-shaped structure, which can be made of various materials, for example, the middle part of the V-shape is fixed on the outer surface of the mask, namely, the upper part is provided with half V-shaped structure when seen from the left side and the right side of the mask body, the left and the right corners of the upper part of the mask are fixedly connected with the V-shaped structure in a sliding way, and the left and the right corners of the upper part of the mask can slide downwards along the V-shaped structure and move towards the left and the right central lines of the mask when the mask is worn; taking the left mask body as an example, a half of V-shaped structure is obliquely fixed on the mask body from the left upper corner of the mask body to the right lower side, and the mask is worn under the action of force, for example, the mouth and nose area in the middle of the mask body is arched by people when people exhale each time, the left upper corner of the mask body drives the upper edge and the left edge of the mask body to move towards the mouth and nose area of the middle person, so that the mask cloth in the mouth and nose area is arched more and more, and a space beneficial to breathing is formed in the mouth and nose area. This effect continues as the mask is worn, corresponding to the trend of active defense. The V-shaped structure is positioned at the left and right ends of the two corners of the mask, and can be lengthened to be fixed on the face or the head, or fixed on the face or the head of a person by connecting other parts, or fixed on glasses by other connecting parts. The structure has a much stronger effect when the mask body adopts a mask without nose bridge strips. The same can be used for fixing the mask rope which is approximately inverted V-shaped at the lower part of the mask body. The N95 three-dimensional mask has a protruding part in the nose bridge region at the upper part of the mask body, so that an approximately inverted V-shaped structure is fixed at the upper part of the mask body. The V-shaped structure may be of similar construction or other constructions of similar principle, such as: the V-shaped book is composed of a left section and a right section, and then a vertical section is connected in the middle of the V-shaped book, which is similar to an upward three-fork structure, or the V-shaped at the upper part of the mask and the inverted V-shaped at the lower part of the mask are spliced together to form an X-shaped structure, and the structures can be in approximate shapes or incomplete shapes, for example, the V-shaped structure can be as follows: there are bent and deformed V-shapes, incomplete V-shapes, etc. The V-shaped structures and the like can be made of various materials, such as rubber, plastic, mask ropes and the like.

The V-shaped structure is positioned at the left and right ends of the two corners of the mask and can be prolonged or fixed on the face or the head of a person through the connecting parts. As shown in the figure, the mask rope with the V-shaped structure between the sliding fixing points passes through the sliding fixing points to be prolonged into the mask rope.

For the mask used on a three-dimensional mask, as shown in the attached drawing, when the mask is opened to be worn, the part of the mask rope can be seen from the right front, namely, the mask rope between two sliding fixing points at the upper part of the mask is spliced into a small inverted V shape, but the whole mask rope which is prolonged to the side of ears is still in a structure similar to the V shape, and the utilization of the mask rope in mechanical aspect is relatively small. So that the shape of the stereoscopic mask can be optimized for better effect.

The beneficial effects of the utility model are as follows: the mask is greatly changed into a structure of decades, and the original three parts are changed into two parts, so that the energy conservation, the environmental protection and the small innovation are greatly promoted, and the charm created by the utility model is displayed. The structure of the mask body can not be changed, and the mask is suitable for mass production, because the existing flaker can be utilized. Thus truly realizing the mask with two parts instead of three parts on the basis of the existing industry.

The cost is reduced because no nose bridge strip is arranged, and the waste mask is favorable for environmental protection recovery. The auxiliary matters are reduced, so that the risk of accidental injury to eyes on the face of a person is reduced, and the mask is a great improvement and is particularly suitable for the mask for children. The nose bridge strip is not needed, so that the production cost of a lot of working procedures is saved, the cost is greatly reduced, and the material is also reduced.

The mask protection article of the application is: the mask, the related parts on the mask, the related articles of the mask, or the related articles of breathing, comprises a small mask for nose and a large mask including a face mask.

The active ingredients and the functional ingredients of the invention are functional substances.

The N95 mask referred to in this application may be a left-right folded N95 shaped mask, i.e., a three-dimensional mask, and also generally refers to three-dimensional masks such as KF94 mask, PFF2 mask, and duckbill mask.

The fixing belt is a mask rope and is a structural component for fixing the mask on the face. The mask cloth also includes facestock or materials for various masks. The invention discloses a special mask rope fixing device for fixing a mask rope, which is used for adding a section of mask rope on a mask surface.

Mask machine clip, clamping jaw, this application also calls the manipulator.

The preferred embodiments of the present application are directed to apparatus that can be manufactured to include the following embodiments or similar embodiments.

The following detailed discussion of the principles of the inventive method is provided in connection with the accompanying drawings and examples:

The method provided by the invention has the starting point that the influences of different material thicknesses of the mask, different material thicknesses of the nose bridge strips and the like are studied, the mask leakage is solved by adopting the mechanical mask ropes and the fixing points, the effect of avoiding the nose bridge strips is better, the problem of later leakage is solved, because the optimal fixing points are some of the problems that the later nose bridge strips cannot be solved, the nose bridge strips have plasticity, and after the mask moves due to the fact that a person speaks, the nose bridge strips are not matched with the position after the mask moves, and obvious leakage joints can be ensured. And when no nose bridge strip exists, good effect can be obtained.

The method of the invention is characterized in that the starting point is to find out the minimum mask rope tension of the leakage seam, so that the auxiliary fixing point is added well, and meanwhile, if the existing mask body is not changed, the method does not have a large breakthrough, and the nose bridge strip is removed as a large breakthrough, so that the mask leakage seam is minimum and the mask rope tension is minimum, and particularly the first problem without leakage seam is realized. The bridge strip or equivalent structure is removed, and the tension of the mask rope is greatly reduced because a hard object is not needed to be fixed. The mask cloth is pushed to the pits on the two sides of the nose bridge of the human face by one section of the mask rope, so that the nose bridge strip can be replaced. Greatly improves the wearing comfort of the mask.

The second big invention point is that according to different mask shapes, the same mask materials are different, the elasticity of the fixing belt is different, the nose bridge strip is different in material, strength, plasticity and deformability, the size is different, or the existence of the nose bridge strip is different; each mask is tested to find out a fixed point with small tension of the fixed belt under the condition that the edge and the face of the mask are not leaked; or only two fixing points at the upper part of the outlet cover are selected;

the term "no leak" as used herein means substantially no leak, and is different from most masks in the prior art in that the leak is obvious. (move down three-stage)

The second biggest invention, several fixation points of the mask have been fixed for many years. The facial shapes of different people are different, the mask body is unreasonable without changing, the mask body is different in thickness and material, the nose bridge strip is different in material and size, and the mask body is unreasonable without changing.

The existing mask, especially the 4 fixing points of the 4 corners of the plane mask, is unreasonable, and needs to be searched again to test the optimal positions of the fixing points in all aspects, namely the optimal positions of the fixing points aiming at the mask.

One of the principles is as follows: the human ear is much higher than the upper edge of the mask, so after the mask is worn, the mask rope has an upward tension to the mask, but the fixing point on the upper part of the existing mask is the outermost side of the upper edge of the mask, so that the upward tension is weakened greatly, and the force of influence of other directions is brought, so that the leakage is promoted due to the large tension. So that the existing mask is worn, especially speaking, it will fall down. Therefore, according to the test, the two fixing points on the upper part of the mask can move towards the lower surface and the middle of the mask body, and the movement towards the lower surface is preferably not more than 30 mm, in particular to a plane mask.

The mask has the advantages that the upward pulling force is generated, the force for straightening the nose bridge strip is reduced, the upward pulling force is increased, the lateral side of the mask body is pulled and lifted strongly, and the lateral side leakage is small. The upward pulling of the middle part of the mask is increased, and the leakage of the upper edge of the mask is small.

Depending on the test, the optimal location of the two fixation points on the upper portion of the mask is selected to also include being in the nasal bridge region, or in the vicinity of the nasal bridge. However, the fixing point moves relatively far toward the middle of the mask, and an auxiliary fixing point or a half fixing point can be arranged at the edge of the mask. The optimal positions of the two fixed points at the lower part of the mask are mostly moved upwards by a certain distance compared with the prior mask.

The nose bridge region is a nose bridge region corresponding to the average nose bridge size of a person where that region is located, because the nose sizes of the person are different.

In so doing, the modification is minimal, the impact is minimal, and the cost is almost unchanged. The tightness and the comfort are greatly improved.

In the third great invention, the fixing belt of the mask has a great potential that is not excavated, and various forces at various positions on the fixing belt are utilized to assist in fixing the mask.

Namely: the effect of the tension force of the existing mask rope on four fixed points of the existing mask is changed, and at least one end of the mask rope is not fixed on the original four fixed points of the existing mask.

In the third major invention, the fixing belt (mask rope and fixing rope) of the mask is not simple, which is important, and many potential energy is not excavated, so that various forces at various positions on the mask can be fully utilized. Or the middle part of the side edge of the mask can be connected with the fixing belt.

The method is implemented by the following steps:

according to the acting force of the human face on the mask through the mask rope, the mask body is searched for the fixed points of 4 new fixed belts or the fixed points of two new fixed belts on the upper part of the mask, so that the mask and the face have good closure performance, and the pulling force of the fixed belts is small; or according to experimental experience: two fixed points on the upper part of the mask can move downwards from the upper edge of the mask, and the fixed points on the upper part of the mask can move from the left edge and the right edge of the mask to the middle:

1. move inwards and outwards:

1. the upper edge of the mask is not a rigid structure, and the two fixed points need to move inwards to a little and move towards the nose bridge direction, so that the lifting effect can be enhanced, and the moving amount is preferably 0.5 to 3 cm; the mask rope can be used for pressing the edge of the mask when moving inwards, but the mask rope can move too much, particularly moves to the nose bridge area, and an auxiliary fixing point is preferably arranged on the edge of the mask.

2. Moving to the middle, reaching the nose bridge or nose bridge accessory area, and arranging auxiliary fixing points outside the mask;

2. move up and down:

the two fixing points at the upper part of the mask can move downwards a little, so that the lifting force is enhanced, but the mask cannot move downwards too much, and the mask body is soft, so that the mask body can be loosened due to too much downwards movement; the N95 mask which is a large amount of N95 mask is folded and stored on the left and right sides, when the mask is used, the left and right sides of the mask are pulled open, such as the N95 mask in the shape of fig. 8, the upper two fixed points move down too much compared with the uppermost edge in the middle of the nose bridge, so that the upper face is easy to loosen, the upper two fixed points of the mask should move upwards or move upwards to be within four centimeters from the uppermost edge of the mask, the scientific two fixed points should refer to vertical upwards, and the mask can move to a position of the nose bridge if the mask is still possible, preferably to find a position which is not too upper and not too lower, the mask periphery is pressed by using the mask fixing belt, or the lower movement amount of the upper two fixed points of the N95 mask is 1 to 4 centimeters compared with the uppermost edge in the middle of the nose bridge, namely, preferably moves vertically upwards to be 1 to 4 centimeters from the uppermost edge, but stops moving upwards if the mask moves vertically to the edge. The disposable mask or the plane mask has soft cloth, and the downward movement amount is 1 to 3 cm or 0.5 to 2.5 cm; here referred to as the vertical distance. Experiments and data on fixed point movements are put at the end.

The fixed point of the plane mask moves inwards towards the X axis, preferably simultaneously moves inwards towards the Y axis, so that the mask rope can press the edge of the mask better. The fixed point moves inwards towards the center line of the mask to reduce the loosening of the middle part of the mask, in addition, the fixed point of the mask rope inwards moves the mask rope to press the edge of the mask, and the mask rope is fully utilized similarly to the addition of the auxiliary fixed point and the addition of other forces of the mask rope to the mask. The purpose of obtaining large technical effect by small modification is achieved.

Or the mask fixing point moves 5 to 30 mm towards the middle of the mask edge, and the child mask moves 5 to 20 mm to serve as a permanent fixing point. The pointer moves the original fixed point of the mask to obtain a new fixed point which is fixed again. On one hand, the movement improves the fixation in the mask, and simultaneously the mask rope is utilized to compress the edge of the mask, so that the edge is not loosened. While if moved too much, additional fixation points may be added at the edges.

Or the two fixing points at the upper part of the mask are also positioned in the nose bridge area or the area near the nose bridge, and auxiliary fixing points are arranged at the edge of the mask;

Similar to fig. 9, or two fixing points at the upper part of the mask are positioned in the nose bridge area or the area near the nose bridge, nose bridge strips are not needed any more, some fixing points can be found through testing, and are generally close to the left and right central lines of the mask, the mask cloth is matched, the nose bridge strips or auxiliary things of the type are not needed, and auxiliary fixing points are arranged at the edge of the mask. The mask rope replaces the nose bridge strip or the equivalent structure. The upper and lower positions may, for example, be selected immediately below the position where the nose bridge is originally secured.

Preferably, the mask rope is relatively large in its attachment points, particularly welded, adjacent the left and right midlines of the mask, so that the entire attachment point falls in the nasal bridge region even though the foremost end is adjacent the left and right midlines of the mask.

The concepts referred to herein generally refer to average values. For example, the bridge sizes of the people are different, and the bridge area is the average bridge obtained according to different people in each region, and when the mask is worn, the mask area corresponding to the bridge is provided. The invention refers to the nearby area, and the length and width of the nearby area do not exceed the length and width of the main body.

The above implementation can also be adopted for the three-dimensional mask such as N95.

As shown in fig. 9, the structure similar to the V-shape is fixed on the upper part of the mask body, the invention is simply called V-shape structure and V-shape, which can be made of various materials, for example, the middle part of the V-shape is fixed on the outer surface of the mask, i.e. the upper part is provided with half of the V-shape structure when seen from the left side and the right side of the mask body, the left corner and the right corner of the upper part of the mask are fixed with the V-shape structure by sliding connection, and the left corner and the right corner of the upper part of the mask can slide downwards along the V-shape structure and move towards the left midline and the right midline of the mask when the mask is worn; taking the left mask body as an example, a half of V-shaped structure is obliquely fixed on the mask body from the left upper corner of the mask body to the right lower side, and the mask is worn under the action of force, for example, the mouth and nose area in the middle of the mask body is arched by people when people exhale each time, the left upper corner of the mask body drives the upper edge and the left edge of the mask body to move towards the mouth and nose area of the middle person, so that the mask cloth in the mouth and nose area is arched more and more, and a space beneficial to breathing is formed in the mouth and nose area. This effect continues as the mask is worn, corresponding to the trend of active defense. The V-shaped structure is positioned at the left and right ends of the two corners of the mask, and can be lengthened to be fixed on the face or the head, or fixed on the face or the head of a person by connecting other parts, or fixed on glasses by other connecting parts such as ropes, rubber bands and the like. The structure has a much stronger effect when the mask body adopts a mask without nose bridge strips. The same can be used for fixing the mask rope which is approximately inverted V-shaped at the lower part of the mask body. The N95 three-dimensional mask has a protruding part in the nose bridge region at the upper part of the mask body, so that an approximately inverted V-shaped structure is fixed at the upper part of the mask body. The V-shaped structure may be of similar construction or other constructions of similar principle, such as: the V-shaped book is composed of a left section and a right section, and then a vertical section is connected in the middle of the V-shaped book, which is similar to an upward three-fork structure, or the V-shaped at the upper part of the mask and the inverted V-shaped at the lower part of the mask are spliced together to form an X-shaped structure, and the structures can be in approximate shapes or incomplete shapes, for example, the V-shaped structure can be as follows: there are bent and deformed V-shapes, incomplete V-shapes, etc. The V-shaped structures and the like can be made of various materials, such as rubber, plastic, mask ropes and the like.

The V-shaped structure is positioned at the left and right ends of the two corners of the mask, and can be prolonged or fixed on the face or the head of a person by connecting other parts, such as glasses, eyepatches, head covering wearing articles and the like. As shown in fig. 2, the V-shaped mask string between the slide fixing points is extended through the slide fixing points to be fixed to ears or heads of a person's face (the mask string of the head). Either the ear or the head-mounted of fig. 2 can be formed into L and V structures as in fig. 1.

For the mask used on a three-dimensional mask, as shown in fig. 8, when the mask is opened for wearing, the part of the mask rope can be seen from the right front, namely, the mask rope between two sliding fixing points at the upper part of the mask is spliced into a small inverted V shape, but the whole of the mask rope which is extended to the side of ears is still in a V-shaped structure, and the utilization of the mask rope in mechanical aspect is relatively small. So that the shape of the stereoscopic mask can be optimized for better effect.

The above implementation can be further implemented in combination with the following:

further or the fixing belt is additionally connected with the edge of the mask, for example, the connection adopts a buckle, paste or clamping structure, or after the mask is worn and adjusted, the fixing belt is fixed with the edge of the mask; or the fixing belt and the edge of the mask are connected in a sliding way, or the edge of the mask is directly pressed to penetrate the seam or the hole of the mask during production, and the fixing belt penetrates the seam or the hole.

The V-shaped and inverted V-shaped fixing parts are not limited to a plurality of fixing points.

Or 2 or 4 auxiliary fixing points are arranged on the mask, the fixing belts are respectively connected with the mask through the fixing points, and the fixing points are densely distributed, so that the fitting of the mask to the face can be increased, and the tension of the fixing belts is not required to be too large, and the tension to ears or heads is reduced; or the fixing belt is connected with an auxiliary fixing point on the branch connecting port removing cover;

additional embodiments (two fixation points at the lower part of the mask are compared with the prior similar embodiments which move upwards):

as shown in fig. 3, the left and right sides of the mask body 9 are respectively connected with an upper fixing strap 11 and a lower fixing strap 11, and when wearing the mask, the upper and lower fixing straps are sleeved on the same ear, so that the middle of the side of the mask can be tightly and tightly adhered to the face, and the side of the mask and the face are prevented from forming a leak or a gap. The mask paste or mask liquid can be coated on the two sides of the nose at the upper edge of the mask to prevent the mask and the face from forming gaps. The principle is that a plurality of fixing points are added on the side edge of the mask body, for example, three fixing points are adopted. Similarly, as shown in fig. 4, one end of the strip-shaped fixing belt is fixed near the middle part of the side edge of the mask body 9, the other end is fixed on the original fixing belt 11 of the mask, and the middle part of the side edge of the mask is also tensioned and attached to the face by tightening the strip-shaped fixing belt after being fixed by the original fixing belt, one end of one section of fixing belt is fixed at the middle part of the side edge of the mask body, and the other end is fixed on the fixing belt of the original ear of the mask; or the original mask body 9 adopts the upper and lower fixing straps 11 to tie the mask body to the head, at least one fixing strap is added between the upper and lower fixing straps of the original mask body. The fixing point of the fixing belt which is added on the side edge of the mask is preferably positioned in the middle of the side edge of the mask.

Of course, the tension of the fixed mask is dispersed to the upper surfaces of the plurality of fixing bands, so that the binding force to the face, ears, head and the like is reduced, and the damage to the skin is reduced. In addition, as long as the fixing bands below the left side and the right side are sleeved on the ears in a reverse way (the ropes above the ears are reversely arranged below the ears, and the ropes below the ears are reversely arranged above the ears), the lower half part of the mask can be covered on the nose, so that the mouth is exposed, activities such as drinking water can be performed, and the upper fixing band and the lower fixing band can be distinguished by adopting different colors or patterns and the like for convenience in recognition. The upper half of the mask can be covered on the mouth in the same way, and the nose is exposed.

The problem of long ear skin pain of wearing the mask and the problem of side leakage of the mask are not solved, the structure has two purposes, and other functions, such as exposing the mouth to drink water and eat east and west or exposing the nose, scratching itch and the like, are also unexpectedly added.

In the mask with the structure of the fixing belt, the problem of side leakage prevention is enhanced, the mask rope is a wide fixing belt, a short fixing belt is added, one end of the short fixing belt is connected with the middle part of the side edge of the mask, and the other end of the short fixing belt is connected with the fixing belt; or as the middle fixing band, the middle fixing band and the fixing band fixed at the lower edge of the mask can be made wider (the middle fixing band and the upper fixing band can be replaced), so that the middle fixing band and the fixing band fixed at the lower edge of the mask are connected together, namely the middle fixing band and the fixing band fixed at the lower edge of the mask form a whole piece of elastic cloth, and the width of the elastic cloth can be reduced from the edge of the mask to the position closer to the ears. This simultaneously eliminates the trouble of connecting the intermediate section with the intermediate section of the fixing strap. The essence of such a side leakage-proof design is that the side is substantially leakage-proof as long as the middle part of the side can be attached to the fastening tape.

Or two fixed points at the lower part of the mask can move upwards by 5-20 mm or 5-25 mm compared with the prior art, and the material thickness can move upwards more, thereby being beneficial to preventing leakage in the middle of the side edge.

Or the leakage of the side edge of the mask is reduced or prevented by using a surface material which promotes unidirectional movement, and the surface material which promotes unidirectional movement is also called as a surface material which promotes unidirectional movement, and various surface materials exist, such as: the unidirectional movement surface material can adopt a mode that a plurality of small particles are fixed on a planar material, the small particles face vertically on one side, the other side is an inclined plane, all the small particle inclined planes face in the same direction, the unidirectional movement material is fixed on the surface of the mask and is pressed under the mask rope, the mask rope can only move towards the direction with the small particle inclined plane relative to the unidirectional movement material, and the other side vertical surface of the small particle inclined plane moves towards the opposite direction, namely, the other side vertical surface of the small particle inclined plane is blocked by the vertical surface. It is also possible, for example, to use tiny particles that are held down on one side, which particles allow unidirectional movement of the two objects relative to each other, and when moved in the other direction, the tiny particles are carried up to hinder the relative movement of the two faces. Two fixing points at the lower part of the mask are arranged on the mask body inside the edge of the mask, and the mask rope is pressed on the edge of the lower part of the mask and then fixed on the ears or the head. The mask is characterized in that the side edge of the lower part of the mask is provided with a surface material which moves unidirectionally relative to the mask rope, the surface material which moves unidirectionally is only required to be arranged on the side edge surface of the lower part of the mask, the area is as small as possible, after the mask is worn on the face, the mask rope of the lower part of the mask is pressed on the unidirectionally moving surface material on the side edge surface of the lower part of the mask, the lower part of the mask can only move downwards relative to the mask rope and cannot move upwards, the side edge is straightened downwards in the moving process of the mouth of the face, and the two side edges of the mask are prevented from going out and leaking.

Comprises the step of finding that the two fixing points at the lower part of the mask body move upwards to reduce the lateral loopholes.

The elastic material fixed point is preferably selected, the position of the fixed point moves downwards along the nose bridge, and because the uppermost edge of the ear of a person is positioned above the uppermost edge of the mask, the fixed band also has oblique tension to the fixed point, and the oblique tension enables cloth on the upper edge of the mask to be closer to the face of the person, so that the tension of the fixed rope can be correspondingly reduced, and the mask is more comfortable to wear. The fixing point can be arranged below the position of the nose bridge strip fixed on the original mask, so that the effect is good, and the position is about 15 mm away from the upper edge of the mask.

The structure adopted by the method of the invention, such as when the middle of the elastic material adopts a left fixed point and a right fixed point or a wide fixed point equivalent to the left fixed point and the right fixed point, can be realized: 1. the mask cloth does not arch at the nose bridge, and two forces are applied to the left and right sides of the nose bridge to the upper edge of the mask: the component force pulled outwards is arranged at the nose bridge, and the inward pushing force is arranged at the outer side (auxiliary fixing point), so that the mask cloth between the two forces can be better acted, and the large pits at the two sides of the nose bridge can be filled. The two forces of the mask with the nose bridge strip can always promote the nose bridge strip at the side edge of the nose bridge to be bent into an arc shape like a large cavity with the mask cloth in the wearing process, so that the fit is kept; the mask without the nose bridge strip does not need people to pinch the nose bridge strip.

The fixing band for binding the mask body to the head by the upper and lower fixing band binding bands is inelastic, so that the elastic material fixed on the upper edge of the mask can be replaced by inelastic material.

When the fixing hole or the annular structure is made into an oblong shape or a groove shape and is arranged up and down, the long fixing belt can pass through the hole or the ring and can also move up and down in the groove hole, so that the corresponding mask body can change the position of the mask body in a small range relative to the fixing belt, and leakage can be reduced by adjusting the mask body to be suitable for the face shape. Further, the structure which can be temporarily locked and fixed such as an adhesive or a buckle can be fixed on the fixing belt, the fixing hole or the annular structure, and after the position of the mask body is adjusted, the relative position of the fixing belt and the fixing hole or the annular structure can be locked and fixed.

As shown in fig. 6, a section of elastic material 129 is provided on the upper edge of the mask at the two sides of the nose, and the two ends of the elastic material are fixed on the mask, so that the connection point of the upper edge of the fixing strap on each side of the mask is not fixed on the mask body 9, but is connected to the outer end of the elastic material 129 on each side, and the outer end of the elastic material 129 is not fixed on the mask. Or a long fixing strap can be disconnected at the nose bridge, and the two ends of the disconnected fixing strap are respectively fixed at the nose bridge of the mask body.

The above structure is of course also applicable to other masks such as N95, and as shown in fig. 8, the ring structure 31 is fixed to the mask body 9, and the head of the fixing strap 11 is fixed to the mask body after passing through the ring structure 31.

Summarizing the previous embodiments, a more optimal approach is presented.

Important problems in implementation:

the structure of the long mask rope is adopted, if the bridge strip is not arranged, the long mask rope spans the bridge of the nose, the mask cloth forms an arch easily at the bridge of the nose because no two sides are pulled, even if the midpoint is provided with a fixed point, the bridge of the nose is not attached, and the leakage-proof effect is poor. The same is true for the case of the nose bridge. The mask ropes on the left side and the right side of the upper part of the original mask are prolonged to be fixed at the position of the nose bridge, and because the welding points of the mask ropes on the left side and the right side of the upper part of the nose bridge have the effect of being outwards inclined to the face by the mask ropes, the upper edge of the mask can be well attached to the nose bridge. It can be implemented as follows: in the middle of the long mask rope, a left fixed point and a right fixed point or a fixed point with the same width as the two points are arranged on the mask, and the mask rope on each side can lead the side of the nose bridge to be subjected to oblique downward tension from the fixed point to the auxiliary fixed point on the side.

Thus, the cloth of the mask body which is separated from the left and right fixing belts and the two sides of the nose bridge has the trend of being separated from each other, the cloth of the mask body which is separated from the left and right fixing belts and the two sides of the nose bridge is leaned against the face of a person, and the nest at the two sides of the nose bridge is filled. However, if the strip-shaped object is only used for being attached to the mask, or the fixing belt is fixedly attached to the surface of the mask, the effect is not achieved.

The design fundamentally changes the mask, and the fixed point is changed for decades, whether the mask is a plane mask or other masks such as N95, and the mask rope can be tightly pulled by the force of not tightening ears.

The design has a huge function, so that a wearer can easily know the middle point of the upper part of the crossing mask, and bend to form an arch to cover the nose bridge, so that the mask cannot be put on askew, most of the existing masks have no structure, the wearer can easily put on askew, uneven left and right stress is caused, deformation is caused, the protection effect of the mask is affected, and the wearer's image is affected when the wearer wears askew.

The following will proceed with a summary of all the embodiments above.

In the above embodiment, the fastening, adhering and clamping structure can be adopted for the connection between the fixing belt and the edge of the mask body, and the fixing belt is fixed after the mask is put on and adjusted. Or the fixing belt and the edge of the mask body can be connected in a sliding way.

Other implementations:

in one embodiment, further comprising: a fixing band 11 and a fixing structure for fixing the fixing band 11 to the mask body 9; the mask body 9 is provided with a fixing hole or a fixing groove; in this embodiment, the fixing hole or the fixing groove is elongated; the fixing structure is arranged on the mask body 9; in the case that the fixing structure fixes the fixing band 11 on the mask body 9, the end of the fixing band 11 is fixedly arranged in the fixing hole or the fixing groove; when the fixing structure releases the fixing state of the fixing band 11 and the mask body 9, the end portion of the fixing band 11 slides in the fixing hole or the fixing groove.

In one embodiment, the fixing structure is a buckle or a magic tape.

In one embodiment, the mask body 9 is provided with a strip-shaped through hole; after the end part of the fixing strap 11 passes through the through hole, the outer surface of the fixing strap 11 is abutted against the inner wall of the through hole.

In order to solve the problem of leakage prevention of the side edge of the mask, in one embodiment, the mask rope is a wide-surface fixing belt, namely, the fixing belt 11 is a flat fixing belt;

in one embodiment, the mask also comprises a short fixing strap, one end of the short fixing strap is connected with the middle part of the side edge of the mask body 9, and the other end of the short fixing strap is connected to the fixing strap 11;

In one embodiment, the fixing band 11 includes: stretch cloth and mask ropes; one end of the elastic cloth is arranged on the mask body 9, and the other end of the elastic cloth is fixedly connected with one end of the mask rope; the other end of the mask rope is arranged on the mask body 9; specifically, a middle fixing band is added, the middle fixing band and the fixing band fixed at the lower edge of the mask can be made wider (the middle fixing band and the fixing band 11 at the upper edge can be replaced), so that the middle fixing band 11 and the fixing band 11 fixed at the lower edge of the mask are connected together, that is, the middle fixing band 11 and the fixing band 11 fixed at the lower edge of the mask form a whole piece of elastic cloth, and the width of the ear can be reduced to be smaller as the edge of the mask is closer to the ear. This simultaneously eliminates the trouble of joining the middle section of the intermediate fixing band with the upper or lower fixing band 11. In essence, this side edge leakage-proof design means that the side edge is substantially leakage-proof as long as the middle of the side edge is attached to the fastening tape 11.

In one embodiment, the mask body 9 is provided with a plurality of auxiliary fixing points; the fixing belt 11 is provided with auxiliary fixing belts which are fixedly connected with a plurality of auxiliary fixing points in one-to-one correspondence; and also has a leakage-proof effect on the expansion side edges.

In one embodiment, the method comprises: a fixing belt 11, a mask body 9 and a leakage-proof structure for preventing the spray from entering or splashing out of the mask body 9; the fixing belt 11 is arranged on the mask body 9; the leakage-proof structure is arranged on the inner surface of the mask body 9.

Or only the two fixing points of the original mask fixing belt positioned at the lower part of the mask are moved upwards by 5-20 mm or the mask material thickness is moved upwards by 5-25 mm, namely the mask fixing belt is moved upwards to the optimal fixing point, and the leakage seam of the side edge is controlled.

The important content is as follows: (fourth invention point)

In the implementation process, the invention is also a great finding, and the invention discloses a squeezing structure of the mask. The existing mask, especially disposable mask, is worn more and more leaked, the mask rope of the existing mask is a motion of pulling the mask body to two sides, but the invention is contrary, the mask of the invention has a plurality of squeezing and pushing actions, such as: because the ears are higher, the mask ropes are turned up from the auxiliary fixing points to the ears, the upper corners can have a squeezing effect on the auxiliary fixing points, and particularly, the mask cloth of the mask body without the nose bridge strips can move more freely, the cloth of the mask body at the upper edge of the mask moves towards the middle in the wearing process of the mask, and the holes at the two sides of the nose bridge are filled. Of course, the better the flexibility of the cloth of the mask body is, the better the effect is, if the soft and thin material is adopted, the crease is easy to be caused, and if the hard and thick material is adopted, the bending movement can not be easy to be caused.

Therefore, when the mask is worn on the face, the mask rope is pulled by hands to be put on the ears, and in the process of pulling up and putting the mask rope, a section of content is already analyzed by pulling up and turning the mask rope when the mask is worn, so that the auxiliary fixing point is pushed and pushed, the action force is the largest when the action force is needed, and when the mask rope is put on the ears, the auxiliary fixing point is pushed and pushed to push mask cloth to be bent towards the concave holes on the two sides of the nose bridge under the push of the mask rope, and the mask with the nose bridge strip is pinched and bent by the mask. The extrusion pushing action can be increased to increase the action of automatic nose pinching, and the invention is implemented earliest: during production, a seam penetrating through the semi-sliding semi-fixing is directly pressed on the left side edge and the right side edge of the upper edge, namely the seam is very small, and only the fixing belt (mask rope) is allowed to pass through, so that the friction force of the mechanical mask rope on mask cloth is large. Or by increasing the friction force between the mask rope and the squeezed mask cloth. The mask body can be promoted to be tightly attached to the face from the auxiliary fixing points in the process of wearing the mask. The design can enhance the squeezing and pushing action of the mask rope, but weakens the squeezing and pushing action of the pull-up and flat ear ropes, and the friction force is large, so that the mask rope can be just used for the mask cloth to be thin, and the squeezing and pushing force is not needed to be too large, otherwise, the mask rope is easy to arch and form seams in the pushing and pushing process. The mask cloth is too thin, and is easy to arch and form seams in the pushing process, so that the auxiliary fixing points can move a little toward the left and right central lines of the mask.

The face width of the mask body can also simply refer to the junction of the front face and the side face of the human face, the auxiliary fixing point corresponds to the face width of the wearer or the face width is smaller, for example, smaller than 2 cm, the comprehensive effect is good, namely, the cloth of the mask body pushed by the mask rope at the auxiliary fixing point is small in the aspect that the gap is filled by cloth, the gap is affected by various influences, the arch is not easily generated due to the fact that the mask cloth is too long or the pushing force is too large in the middle of wearing, and compared with the gap opening effect is better than that of the hole opening or the ring.

The auxiliary fastening points can be any kind of fastening means, such as holes, slits or ring structures, as long as they are slidingly connected. What is important is: the auxiliary fixing points are preferably arranged at the left and right positions of the face width or within the face width, so that the mask cloth has good extrusion force towards the middle of the mask, and the auxiliary fixing points are implemented by the following steps: the mask cord will not press the mask cloth outside the auxiliary fixing point, because the mask cord presses the mask cloth therein to cause a large moving friction resistance. In order to fix the mask, the design and the mask in the prior art can certainly press the edge of the outermost side of the mask, thereby fixing the whole mask. The friction force with the face is large, the pushing effect is poor, the auxiliary fixing point is too far outside, the cloth to be pushed is too long, and arching is easy to occur, especially when the ears are worn.

The embodiment is that two auxiliary fixing points of the left side and the right side of the mask with the mechanical mask ropes are provided with holes or slits, the pushing effect is just or less than the width of a human face, the effect of pressing mask cloth by the mask ropes is reduced, the mask is different from the existing mask, the width of the existing mask is required to be wider than the width of the face because the protection performance is considered, the most important implementation of the auxiliary fixing points is that the side edges of the mask are provided with slits or holes, the distance from the side edges is generally 5 to 15 mm, the position is just close to the width of the face of most people after the mask is worn on the face, and most of mask cloths are also suitable, so the embodiment has very good effect, and the dynamic effect of the mechanical mask ropes is added, so that the whole mask is worn on the face, and the whole mask has higher air tightness and stronger protection force when the whole mask is worn on the face.

The mechanical mask rope is matched with the auxiliary fixing point, and has the pushing effect in the wearing process. Because the spray is parabolic, it is important to prevent leakage from the upper edge of the mask and also to prevent leakage from causing fogging of the ophthalmic lens. However, in the whole wearing process, the upper edge of the common mask cloth is larger and larger.

The effect phenomenon is similar to that of an artificial intelligence mask, the mask is worn to be adjusted, so that leakage is reduced as compared with the mask, and leakage is reduced continuously according to teaching of people when the mask is worn in the whole process.

The gauze mask of this kind of structure, its meaning and effect are very big, because many people wear the gauze mask all do not understand in the world and get hold of the bridge of the nose strip to reduce the gauze mask and go up border leak, consequently current disposable gauze mask has the danger of revealing, say: children, lazy people, do not want to often pinch the nose bridge to reduce the upper edge leakage. Some people who fall behind and have poor health protection education are not careful about these important details. The mask of the present invention allows those to reduce the risk of leakage. Often, the nose bridge strip is removed from being pinched to touch the mask, so that cross infection is caused.

The left side and the right side of the upper edge of the mask body are provided with holes or slits, the holes or slits are arranged in the width of the face of the person wearing the mask on the mask body, and in order to prevent the corners of the mask from tilting, the corners of the mask can be 3 cm inwards; the mask body may be further provided with slits extending inward from the side edges of the left and right sides of the upper edge of the mask body, the slits may be opened so as not to penetrate the mask body, and the wearer may tear the slits toward the center line of the mask according to the face width of the wearer, or the wearer may tear the mask body, or the wearer may assist the fixing point to open a long groove as in the previous embodiment, but the length of the groove may be adjusted by means of fastening, tightening, adhering, or the like, so that the distance between the auxiliary fixing holes of the left and right mask strings may be adjusted as close to the face width as possible. A gauze mask for being used for than ordinary gauze mask material of a lot of, can also adopt reinforcing effect: for example, the mask cloth contacted with the face at the periphery of the auxiliary fixing point is made into a smooth surface, even the mask cloth contacted with the mask rope is made into a smooth surface, for example, the outer surface of the mask in the direction from the periphery of the auxiliary fixing point hole or seam to the center line of the mask body is provided with a surface material which moves unidirectionally relative to the mask rope in the previous embodiment. Of course, if the mask cloth is made of a memory material, the mask cloth has a more perfect effect.

Face width refers to the width of the face and may generally refer to the distance between the highest points of the two cheekbones. The face width and face width of the present invention mean the average face width of the wearer in the region of use. The auxiliary fixing point is arranged at the wide face position, namely the position of the mask corresponding to the wide face after the mask is worn on the face of a person. However, the perforation or seam may move toward the midline of the mask, but not so much that the corners of the upper portion of the mask of this material do not warp up as they are not pressed by the string. The auxiliary fixing point is arranged at the average face width, and the auxiliary fixing point is outward a little, or inward a little, for example, the auxiliary fixing point is less than five millimeters, so that the effect is poor. I.e. or an auxiliary fixation point is provided within a range differing by plus or minus 5 mm at the wide width of the face corresponding to the left and right sides.

The punching or sewing can be implemented in this way, the ring is replaced, the structure similar to the ring with the same ring is arranged at the upper edge of the two sides of the upper edge of the mask, and the mechanical mask rope passes through the ring, because the upper edge of the mask is reached, the earrope is obliquely worn on the ears after passing through the similar ring with the same ring, the earrope can not be pressed to the mask cloth outside the similar ring with the same ring, no resistance is formed, and the mechanical mask rope can be pushed to the middle by pushing the ring, so that the cloth at the two sides of the mask can be pushed to the middle.

The invention has the advantages that the small details found by the invention have great effects, namely the technical effect is great, the adopted design reduces the influence on the movement of the mask cloth because the mask cloth is pressed, the mask cloth is convenient for the mask rope to push the mask cloth to move towards the center line of the mask, and the mask cloth is also a skin patch towards the face. The mask leak can be filled with the structure, and the side leak can be reduced.

In the wearing process, the leakage of the mask and the face is smaller and smaller, because the mask is provided with the function of moving the mask towards the front of the face no matter breathing or speaking, the inlet mask cloth is promoted to move towards the front of the mouth and nose, and the mouth mask cloth at the upper edge of the mask continuously fills the holes at the two sides of the nose bridge, and the cloth at the two sides of the mask continuously clings to the face of a person forwards to the middle.

The mask also has an automatic effect, and the application also provides important findings and inventions as follows: the similar structure can make the mask cloth move continuously to be close to the face of a person by utilizing the action of the mask rope or the action of face movement. The mask is provided with auxiliary fixing points, a structure is adopted, wherein the structure is used for reducing or avoiding the influence on the cloth movement of the mask body due to the pressing of the mask rope, and the cloth of the mask body is close to the skin movement of the face of a person from the auxiliary fixing points relative to the mask rope under the action of the rope or the action of the face movement of the person. I.e. can be implemented as follows: auxiliary fixing points are arranged on the left side and the right side of the upper edge of the mask body, the auxiliary fixing points are arranged close to the face width (face width position) of the wearer or smaller than the face width of the wearer, and the mask rope leaves the mask from the auxiliary fixing points to go behind the ears or the brains of the wearer. The opening or the seam is easy to realize, the auxiliary fixing point adopts a ring-shaped structure, and after the mask rope passes through the ring, the mask cloth is pressed to a point, and then the mask cloth can leave the mask to go behind the ears or the brains of the person, and then a point can be moved by the middle part of the mask. Holes or slits can also be formed at the positions corresponding to the width of the face of the wearer on the mask body.

The mask with the structure fills the leakage seam and can reduce the side edge leakage seam, and for the existing mask, because the nose is upwards supported and the chin is downwards moved, the mask body at the side edge is upwards pulled downwards, and when the mask body is severely pulled, the leakage seam exists on the contrary, the mask disclosed by the invention: under the action of the mechanical mask rope, the auxiliary fixing points and the elements without nose bridge strips, the auxiliary fixing points on the upper part of the mask can be more flexible, and the side leakage is smaller and smaller according to the multidimensional movement of the face of a person, so that the automatic adjustment is realized. The upper edge of the existing mask is provided with a nose bridge strip, and the nose bridge strip almost occupies the width of the whole mask, so that the lateral movement of the mask side is limited, and the longitudinal movement of the mask side is also limited. The folded structure and the bridge-free strip can be matched well.

Therefore, the combination can effectively reduce the leakage of the mask and the face in the process of wearing the mask.

Since this structure has such an effect, the same can be applied to other positions of the mask. The mask is characterized in that an auxiliary fixing point is arranged at the edge of the mask, the auxiliary fixing point and the mask rope are in sliding connection, the mask rope moves towards the middle of the mask through the auxiliary fixing point in the horizontal coordinate and/or the vertical coordinate and then is fixed to a new position to serve as the fixing point, the auxiliary fixing point adopts a structure for reducing or avoiding the influence on the cloth movement of the mask body caused by pressing of the mask rope, or the auxiliary fixing point adopts a structure for reducing or avoiding the influence on the movement of the mask body, which is filled with the cloth of the mask body and is pushed by the mask rope. The structure is that under the action of the mask rope or the action of the face movement of the person, the mask rope at the position of the mask body corresponding to the auxiliary fixing point moves towards the fixing point, and the fixing point is close to the middle part of the face corresponding to the auxiliary fixing point, so that the mask body is also tightly attached to the face skin.

Important findings and practices: (fifth big invention point)

The mask is molded to be beneficial to the shape of the nose bridge, including the means of folding and the like.

The invention relates to a plane mask, such as a disposable mask, which is characterized in that the left and right sides of the mask are not folded along the center line, namely the plane mask is called as the plane mask. The plane mask is folded in half to have great technical effect: the use is convenient, the wearing bias is avoided, and the centering is not required to be found; the folding has the advantage that the middle cloth can be lifted to be far away from the mouth and nose of a person when the mask is worn, i.e. the wet lips can not be touched; the storage is convenient, and the occupied area is small; when the folded plane mask is worn, the left and right sides of the mask have the trend of leaning against the left and right faces, and the effect of reducing the side leakage of the mask is achieved.

The conventional N95-shaped mask is generally folded in left and right, for example, as shown in fig. 8, but there is no gap between the left and right folds, the middle of the nose bridge strip is folded into an angle close to 0 degrees, and the mask is not attached to the nose bridge after being worn on the face.

The other important finding of the invention is that the mask is folded in half, namely the left side and the right side are combined together, and the bending part of the nose bridge strip is provided with an angle and an radian, so that a gap can be reserved between the left side and the right side of the mask, for example, a gap of about 5 mm or a gap of 3 to 8 mm can be reserved, and thus the bending part can have a small angle and radian, which has a plurality of advantages, such as: because the arc is arranged in the middle of the nose bridge strip, the nose bridge strip is easy to be attached to the nose bridge after the mask is worn on the face, and the leakage is reduced. The existing plane mask, such as a disposable mask, particularly a mask which adopts the mechanical mask rope and has no nose bridge strip, has the following technical effects: after the mask is folded, the material at the center line of the mask keeps the radian when being stored, after the mask is worn on the face, the mask is very easy to be attached to the nose bridge, the left side and the right side of the mask which are folded in the half are provided with the trend of protecting the nose bridge, meanwhile, the cloth on the upper edge of the mask is pushed by the mechanical mask rope, the leak on the two sides of the nose bridge is very easy to be filled, that is, the folding is the modeling of modeling the nose bridge for the mask at the center line, and the disposable mask can be used for: the mask is worn without pinching the nose bridge strips, and can fill the leaks at the two sides of the nose bridge only by wearing the mask on the face, which is equivalent to playing the effect of preventing the leaks by pinching the nose bridge strips by a wearer, and the mask is very simple to wear. The mask is equivalent to an intelligent mask which can be adaptively adjusted according to the face and the nose of a wearer, and the function of filling the leakage is continuous in the whole wearing process of the mask, so that the mask is also an active defense type mask. The specific production can also be implemented in such a way that a plurality of masks, such as a plurality of masks, are folded together except that a single mask is directly folded in half, and then folded in half, so that gaps are reserved between two sides of the folded masks, and then packaging and other treatments are carried out.

The mask rope is provided with a structure for pushing the mask cloth to face, at least one end of the mask rope is not fixed on the original fixed point of the existing mask, the mask is worn without pinching nose bridge strips, and the two-side leakage of the nose bridge can be filled only by wearing the mask, which is equivalent to the effect of preventing the leakage by pinching the nose bridge strips by a wearer, and the wearing is very simple; whereas for existing masks with nose bridge strips, a curve that is worn on the face more closely to the face.

Further, from overlooking or looking up, the mask is folded into a V shape, the middle folio sharp angle and the nose tip are in the same direction, the mask can be folded into a W shape, the middle folio sharp angle and the nose tip are in the same direction, the folding angles at the two sides respectively fall into the nest between the two sides of the nose bridge and the cheekbones, the mask can be more quickly attached to the face of a person, and the mask is folded into the W shape, the length is reduced greatly, and the mask is more convenient to carry and store.

Or the lower surface of eyes of an adult is pre-shaped into a face shape curve including nose bridges, mainly the upper edge of the mask is pre-shaped into three peaks, the mask is worn on the face, the three peaks are respectively covered on left cheekbones, nose bridges and right cheekbones, the mask is shaped in at least one of the links of production, processing, packaging, transportation, storage and the like, or the upper edge of the mask is fixed by adopting an auxiliary frame with the three peaks for shaping when the mask is stored.

The mask can be shaped into a shape favorable for the bridge of the nose under the same conditions of the temperature, the humidity and the like of the face of a person, then the conditions are changed, the mask is flattened, when the mask is worn on the face, the mask is restored into the shape favorable for the bridge of the nose under the conditions of the temperature, the humidity and the like of the face of the person. Similar to these memory materials, the prior art is numerous and not described in detail herein.

The mask is molded in advance on the mask to be beneficial to the modeling of the nose bridge, and the implementation of the method also has a great technical effect, so that the mask is greatly promoted to have an automatic effect. Because the mask rope is used for extruding and pushing auxiliary fixing points so as to extrude and push mask cloth to lean against a human face, the mask is possibly supported by a mask with too thick mask cloth material, the mask is molded into a shape beneficial to nose bridge in advance, the mask cloth is bent to form a plurality of fine folds, and when the mask cloth is supported and not moved, the mask cloth is bent to lean against the human face due to the folds. The mask is different from the existing mask in folding, a certain bending arc is required at the folding position, and gaps are reserved on the left side and the right side of the mask, so that fine folds are formed on the larger area of the mask cloth. Therefore, if the mask is not molded in advance to be beneficial to the modeling of the nose bridge, the upper edge of the mask, particularly the mask cloth corresponding to the nose bridge and the two sides of the nose bridge, is also subjected to pretreatment such as bending or rubbing in advance, so that a plurality of fine folds or small wrinkles are formed, and the lines are up and down along the mask.

This is a significant technical advance in masks, particularly disposable masks. The mask is significant for the people with poor protection consciousness in the backward region and the people who cannot wear the mask.

Of course, if the mask cloth is matched with a material with special properties, the mask cloth can have better and more effects.

Further implementation:

the invention is also important for the structure of the invention, so the invention is widely accepted for wearing comfort, and the lip part needs to have a supporting structure to prevent the mask from touching the lips. Thus, the mask at the mouth and nose has large ventilation area.

Because most of the existing plane mask has folding folds at the lips, for the plane mask, the left side and the right side of the mask are folded in half along the central line, the inner surface of the mask is folded inside by the outer surface, when the mask is used, after the mask is unfolded, the region of the mask corresponding to the lips is not provided with the folding folds of the mask, and the region of the mask corresponding to the region except the lips is provided with the folding folds; or when the mask is opened, the region of the mask corresponding to the upper lip is not provided with folding folds of the mask, and the region of the mask corresponding to the region except the upper lip is provided with folding folds; the fold of the mask is not arranged on the mask: when the mask is used, the region of the mask corresponding to the lips is opened, and the mask is avoided and arranged above and below the lips; because the lower lip is most likely to protrude from under the nose to the chin, or at least in the region of the mask facing the lower lip, the overall folded pleat of the mask closest to the lower lip is not at a higher level than any portion of the upper lip, so that the middle portion does not touch the lower lip after expansion, even though the folded pleat is at the level of the lower lip. When the mask is worn, the middle cloth can be lifted to be far away from the mouth and nose of a person, namely, the wet lips can not be touched. Especially a mask without nose bridge strips.

The mask is folded left and right along the central line, the middle of the transverse folding fold of the plane mask is utilized to be convex, the mouth and nose area is supported, the folding in temporary use cannot be achieved, and the best effect is that the folded central line is required to be folded to form wrinkles. And more than 4 transverse folding creases are preferable.

Further, in order to enhance the effect, no matter in the mask which is not folded in half, a plate or a strip can be transversely arranged in the middle of the mask, the length of the key plate or strip is long enough, and the length is as long as the length of the folded wrinkles, namely, no virtual position is left (the technical effect cannot be achieved due to the fact that the virtual position is left in the prior art), that is, the end (side pressure welding part) of the left side and the right side folded wrinkles of the mask can be contacted, and the face can be supported.

The two ends of the support bar are the most critical, and the two ends of the left and right side folding folds of the mask are required to be abutted against the ends of the left and right side folding folds of the mask, so that the support bar can indirectly support the face of a person, and only the support bar can play a supporting role, and the support bar corresponds to the key position provided by the invention again. The prior art or products have not achieved technical results because this problem has not been found, and have not been implemented because the side edges of the welded mask produced above have been welded to the plate or strip, which has not been solved. The mask production equipment can be processed in this way, the equipment is provided with equipment for fixing the strip-shaped object with the same length as the length of the folded fold at the middle part of the mask, or equipment for fixing the strip-shaped object in the interlayer of the mask, and a notch is arranged on the pattern on the welding roller or the welding plate rod at the pressing part of the side edge of the welding mask, and the notch is used for avoiding the plate-shaped object or the strip-shaped object which is not to be pressed and welded at the middle part of the mask.

The invention solves the problem that the two ends of the plate-shaped object or the strip-shaped object must be abutted against the ends of the folded wrinkles on the left side and the right side of the mask, because if the supporting bar is abutted against the left side and the right side in production, the ends of the supporting bar are possibly pressed when the layers of cloth of the mask on the left side and the right side are welded, so that the welding is caused, the inner surface and the outer surface are hard to see and the protection is influenced.

The plate-shaped objects or the strip-shaped objects can be clamped in the folds, which are closest to the lower part of the lower lip, of the inner surface of the mask, so that the mask is not easy to loosen and shift.

Or transversely press-welding transverse welding lines on the mask cloth at the middle part or between the lower part of the nose bridge and the upper part of the mouth, and supporting the welding lines on the face when the mask is worn.

The plate-shaped object or the strip-shaped object is arranged on the mask and is folded along with the mask, when the mask is opened to be used on the left side and the right side, the middle of the mask is supported by the plate-shaped object or the strip-shaped object to be supported, and the two sides of the mask have a folding trend, so that the two sides of the mask are promoted to be folded to be close to the faces on the two sides, and particularly the plate-shaped object adopts plastic rather than brittle materials or memory materials.

The plate may be replaced by a strip.

Further, the plate-shaped object can be made of paper boards, the front side and the back side of the paper boards are made of different materials or different treatment processes, so that the paper boards have a tendency of bending towards one side at ordinary times, for example, the front side and the back side of the paper boards are waterproof, and the waterproof side is not waterproof, so that the waterproof side can absorb water vapor exhaled by people in the using process of the mask, expansion occurs, the waterproof side is not expanded, the expansion side is internally covered with the non-expansion side, and the paper boards are bent. When the mask is fixed on the mask, the inner cambered surface of the paperboard faces inwards to the face, and the opposite bow faces outwards, so that the mask material can be supported away from the face. In the using process of the mask, the mask is folded again and unfolded after being stored, and the paperboards keep arc shapes. This is by way of materials. And after the paper board is folded in half, the paper board is conveniently opened into various angles during opening. The same cardboard can be replaced by other materials with different materials or different treatment processes on the front and back sides, so that the materials are bent to one side at ordinary times.

The leakage prevention of the upper edge of the inlet cover is promoted and the leakage prevention of the side edge is promoted. The plate-shaped or strip-shaped object can lift the mask off the mouth, so that the problems of being stained with lipstick and the like are avoided, and the mask can be folded or unfolded before use and can also be used for the existing mask.

The transverse welding lines do not need to be supported on the face, for such three-dimensional masks as N95, KF94 and the like, nose bridge strips are not adopted, and when the mask cloth on two sides of the nose bridge is collapsed to large concave holes on two sides of the nose bridge after being pushed, in order to keep the three-dimensional space structure of the mask unaffected, the transverse welding lines are required to be transversely pressed and welded on the mask cloth between the lower part of the corresponding nose bridge and the upper part of the mouth, and the welding lines are more than two; if the welding lines are one, then: the weld lines are thicker than on existing masks, or the weld lines are next to auxiliary or fixed points of the edges and are connected uninterrupted from the left edge to the right edge. Such arrangement of welding lines plays a role in: the nose bridge deformation area and the mouth three-dimensional area are separated, so that the nose bridge deformation area is deformed, and the mouth three-dimensional area is not deformed.

In order to make the mask cloth in the nose bridge deformation area easier to deform, the cloth at the position of the mask opposite to the nose bridge can be softened, for example, the press-welding patterns at the position are reduced, and the press-welding patterns for fixing the nose bridge strips are all the hardening treatment of the mask cloth at the position. The area of the mask facing the nose bridge is used as a soft deformable area, which is beneficial for the mask cloth to be tightly adhered to the periphery of the nose bridge.

Or more cloth is added at the position of the mask facing the nose bridge; except for the addition of a mask cloth.

Other important examples:

the plane mask is provided with a plurality of transverse folding folds, each folding fold can fold a small fold to come out, the small fold can be leveled when the mask is used, the surface area of the mask is prolonged, the uppermost folding fold is positioned outside the mask, namely, the small fold folded out of the uppermost is positioned outside the mask, and the folding fold is not arranged inside the mask, namely, is not blocked between the mask cloth and the face of the rest upper part of the mask connected with the folding fold. The mask cloth at the upper part of the rest mask can move towards the face to fill the pits at the two sides of the nose bridge. Or under the condition that the cloth of the innermost layer and the cloth of the outermost layer are not mutually exchanged, the original folding fold direction is kept unchanged, the traditional plane mask is rotated 180 degrees along the plane, the lower part is used as the upper part, and the upper part is used as the lower part, namely, the upper and lower parts of the mask body are used in a switching way, and the mask can also be realized.

The same effect can be achieved by arranging a connecting structure similar to the upper edge at other positions of the mask, such as the lower edge, specifically: the fixed point of the lower part of the mask rope is fixed in the chin area, and the lower part of the side edge of the mask is provided with an auxiliary fixed point, so that the mask cloth on both sides of the chin can be more attached to the face.

Such three-dimensional masks as N95 and KF94 may be further implemented as follows: for better effect, the mask can be further arranged in the nose bridge area to be added with mask cloth, as shown in fig. 8, the right side of the mask is provided with an upper section, a middle section and a lower section of welding cutting line, and the included angle between the upper section and the middle section is only required to be increased, so that more mask cloth is more beneficial to filling the holes on the two sides of the nose bridge. Preferably, the included angle between the upper welding cut line and the middle welding cut line is increased, and the structure shown in fig. 5 is adopted, so that the upper section and the middle section are not directly connected, and a welding cut line with a transverse transition is further connected in the middle. Or the mask cloth is left with a plurality of protruding mask cloths at the left and right upper two corners or the four corners when being cut compared with the existing mask, as shown in figure 7, the upper edge of the original mask is straight line and even concave, or the upper edge of the mask is left with a plurality of protruding mask cloths when being cut compared with the existing mask; the specific steps can be as follows: the mask is made to be arc-shaped to protrude, or the upper edge of the mask is lengthened by one section, or the left and right sides of the middle are made to be two arc-shaped to protrude.

The two sliding fixing points at the upper part of the mask move upwards.

The mask cloth for increasing the nose bridge area is obviously increased compared with the existing mask, and the size of the mask cloth in a certain direction can be more than 3 mm, or the average length of the upper edge of the mask where the nose bridge area is positioned is 5-16 mm or more than 5 mm longer than the average length of the existing similar mask.

Or the cloth of the mask facing the nose bridge is softened, and the pressure welding patterns are reduced.

Or transversely press-welding transverse welding lines on the mask cloth between the lower part of the corresponding nose bridge and the upper part of the mouth, wherein more than two welding lines are adopted, or if one welding line is adopted, the welding lines are formed: the welding lines on the mask are thicker than those on the existing mask; and/or the weld bead is next to an auxiliary or fixed point of the edge and is connected uninterrupted from the left edge to the right edge; the welding lines divide the nose bridge deformation area and the mouth three-dimensional area.

Or the mask is matched with a nose bridge strip which is thinner or smaller than the prior mask, thus being more matched with the nose bridge when being skin-friendly. The selected sites can also use very small nose bridge strips even if nose bridge strips are used, so that the damage is reduced, the cost is reduced, and the softness and the comfort of the mask are improved.

Such an implementation may force the mask to have nose strips for some applications.

Or the mask comprises a mask body and fixing belts, wherein the heads of the fixing belts are fixed on the mask body, two fixing points which are the outermost sides are found in the peripheral area of the nose bridge strip, and the left and right fixing belts on the upper part of the mask are connected with the fixing points, so that the left and right fixing belts are pulled at ordinary times and cannot cause obvious deformation of the arch formed by bending the nose bridge strip by the nose bridge, and the tightness of the mask is reduced; or the left and right fixing belts at the upper part of the mask are connected with two fixing points of the mask corresponding to the region near the nose bridge, the edge of the mask is provided with an auxiliary fixing point, and the nose bridge strip extends to the auxiliary fixing point. When the mask is used for a very thin mask, the upper edge of the mask possibly arches at the position without the nose bridge strip under the action of the mask rope, so that leakage is caused, and a new structure for extending the nose bridge strip to an auxiliary fixing point is adopted. Or many embodiments can be provided with the nose bridge strip, the nose bridge strip adopts U-shaped elastic materials, the arc in the middle of the U-shaped nose bridge strip is sleeved with the nose bridge of a person, and two sides of the U-shaped nose bridge are provided with holes for elastically pressing and springing the two sides of the nose bridge. The problem that the plastic nose bridge strip cannot be attached to the displaced position to generate leakage when the mask is displaced during the speaking movement of the mouth is solved.

Two fixing points below the mask move upwards by 5-20 mm; or the two fixing points at the lower part of the mask are moved upwards by 0.5 to 2.5 cm, and the upward movement amount of the two fixing points at the lower part of the children mask is 0.5 to 3 cm. In reality, more or less leaks are arranged on the side edge of the mask worn by a plurality of people, and the lower fixing points move upwards, so that the leaks are pressed, and the edge of the mask is made to be in contact with the face.

Two fixed points below the mask are moved upwards for 5-20 mm for welding; or the two fixing points at the lower part of the mask are welded by moving upwards by 0.5 to 2.5 cm, the upward moving amount of the two fixing points at the lower part of the child mask is 0.5 to 3 cm, and the child mask is welded to the mask beside the welding lines of the edge sealing edges of the mask or welded to the welding line areas of the edge sealing edges of the mask.

The chin of the mask speaking drives the mask to move downwards more easily, so that the mask is easier to shift, in particular to a N95, KF94 and other three-dimensional masks, and after the nose bridge strip shifts, the mask is shaped again to a new position, so that air leakage is necessarily caused, and the technical effect is not realized. And leaks have a significant impact on aerosol protection. Therefore, no nose bridge strip is arranged on the mask, and the technical effect can be realized only by preventing the mask from sliding in the wearing process, which is also based on the invention: the bridge strip can instead be based on the significant discovery that the mask is displaced and then exposed. It is important to attach materials with high frictional resistance to the face or nose bridge where they contact. The mask is matched with a material with high friction force to play a role in preventing the mask from moving, and the material surface of the original mask corresponding to the part can be roughened, such as scratch or pressure welding lines, by arranging an additional material with high friction force, such as rough cloth or paper, with fine material on the inner surface of the mask opposite to the nose bridge area. The implementation is different from the prior art in that the sponge strips are simply stuck on the upper edge of the inner surface of the mask, and firstly, the requirements of materials are different; secondly, the function uses are different, the sponge strip in the prior art is used for filling the leaks at two sides of the nose bridge, so that the sponge strip is long and is generally thicker, small leaks are easily generated at the end of the sponge, weather heat can be uncomfortable, more importantly, the gap of the sponge material is large, the filterability of viruses, aerosols and the like is poor, and too much thick sponge is equivalent to larger leaks. The key point of the invention is that: the friction force which can truly prevent the upper edge of the mask from sliding downwards is mainly a small area right in front of the nose bridge. The preferred implementation is therefore: the mask is processed into a rough surface or is provided with an additional material with high surface friction force in the area right in front of the nose bridge. Summarizing: the size is very different with current, and prior art sponge strip is generally longer than the bridge of the nose strip, and general lateral length is greater than 8 centimetres, and the material that the frictional force is big of this application is established at the gauze mask internal surface and is opposite to the bridge of the nose region, and lateral length is generally less than 5 centimetres, if just facing to bridge of the nose in front of even within 2 centimetres is enough, and the thickness of current sponge strip is about 3 millimeters in addition, and the material thickness that the frictional force is big of this application is within 1 millimetre. The material with high friction force is a material with high friction force compared with the inner surface of the existing mask, and the non-woven fabric of the outermost layer of the mask is rough compared with the non-woven fabric of the innermost layer of the mask, so the material with high friction force can be directly used for the non-woven fabric of the outermost layer of the mask.

Or the inner surface of the mask can be provided with an additional material for absorbing moisture in the areas facing the nose bridge and the two sides of the nose bridge, so that the problem of preventing the spectacle lens from fogging is solved. These may of course be provided on other masks such as a flat surface.

In addition, because of the three-dimensional mask such as N95, KF94 and the like, besides holes and seams, the annular structures can be fixed on two sides of the upper edge of the mask to serve as auxiliary fixing points, and the prolonged mask ropes penetrate through the auxiliary fixing points.

The method adopts the structure that the left and right sides of the nose bridge to the upper edge of the mask have two forces: the component force pulled outwards is arranged at the nose bridge, and the inward pushing force is arranged at the outer side (auxiliary fixing point), so that the mask cloth between the two forces can be better acted, and the large pits at the two sides of the nose bridge can be filled. The two forces of the mask with the nose bridge strip can always promote the nose bridge strip at the side edge of the nose bridge to be bent into an arc shape like a large cavity with the mask cloth in the wearing process, so that the fit is kept; the mask without the nose bridge strip does not need people to pinch the nose bridge strip.

Or the inner surface of the mask is also provided with a bag-shaped structure, the opening of the bag faces to the mouth-nose area, and the opening is in an open state; the simple type or the structure is characterized in that a moisture absorbent storage area is arranged on the bag wall of the bag-shaped structure and/or a metal filament wire is connected in the bag. The bag with the bag-like structure contains various functional substances and effective components such as medicines such as plant extracts as required.

Finally, the implementation of the method of the invention is responded:

that is, the different site effects will still be different, and there is a problem of optimal fixation points, which also relates to the core method of the present invention, and is a problem of the present invention to the site fixation points or fixation point areas mentioned throughout, whether the present invention is to find the fixation site for glue adhesion at the earliest or to find the fixation site for an elastomer or a fixation band at the later time. Such as: the two fixing points on the upper part of the mask are required to move downwards. In practical tests, if the two fixing points on the upper part of the mask are too close to the upper edge of the mask and are positioned above the original position of the nose bridge strip of the mask, the small gaps are formed between the upper edge of the mask and the face, but the fixing points move downwards and are positioned below the original position of the nose bridge strip of the mask, so that the small gaps are not formed. The fixing points are positioned below the side auxiliary fixing points, and in this implementation, similar to fig. 9, two sections of mask ropes at the upper part of the mask are not in a straight line, but the middle fixing points are low, and the two side auxiliary fixing points are high. In addition, the mask rope is inclined, the auxiliary fixing points move the mask cloth along the direction of the mask rope to be pushed to the mouth-nose area in the middle of the mask, and the effect that the smaller the leakage is, the more the mask is worn on the periphery, the more the face is attached to the mask is realized. This problem is present both with and without the nose bridge.

According to the principle of the invention, the structure of the invention can be applied to the existing mask, and also can be applied to a new mask, a new material mask and a new structure mask.

Experiment and test

Because the movement of the fixing points relates to the plane mask more, the plane mask is mainly used for preventing spray, so the requirement on the adhesion is not high, namely the air leakage around the mask is also allowed. Therefore, the experiment mainly adopts the judgment of an experimenter, and 6 adults, 3 men, three women, 6 children, 3 men and three women are respectively selected.

The fixed point movement is as follows: when the side edge leaks, two fixed points at the lower part of the plane mask move upwards by 5-20 mm; or the two fixed points at the lower part of the mask move upwards by 0.5 to 2.5 cm, and the upward movement amount of the two fixed points at the lower part of the children mask is 0.5 to 3 cm; or when the upper edge leaks, the two fixing points at the upper part of the mask move downwards and towards the middle part, the moving amount is 0.5 to 3 cm, and the moving amount of the child mask is 0.5 to 2 cm; or when the upper edge leaks, the two fixed points at the upper part of the mask vertically move upwards to be 1-4 cm away from the uppermost edge of the mask, and the children mask is 1-3 cm; meanwhile, the edge of the mask is pressed by the mask rope.

The method comprises the steps of wearing a common mask and various masks after moving a fixed point by each person, blowing air into the mask each time, feeling air leakage around the mask by hands, summarizing the sizes of the side air leakage corresponding to the feeling mask by individuals, judging after a plurality of times, and carrying out an adhesion test on each implementation of the method and the common mask, wherein the data of the same class are selected as follows, so that the effect is good, and detailed detection reports of each embodiment can be checked on a official network, and the table 2.
