Description

mask {MASK}

This design relates to a mask, and more specifically, by manufacturing the product in an ergonomic and compact size, it minimizes the contact area between harmful gases from exhaled breath (carbon dioxide generated in the lungs and stomach acid generated in the stomach) and the skin, thereby protecting the skin. Trouble can be minimized, and exhaled breath is directed to be discharged from both ends of the corner of the mouth downwards to the left and right sides of the chin, preventing droplets from being released into the air in front of the face. This is about a mask that allows the wearer to breathe comfortably and feel a pleasant environment by quickly discharging generated carbon dioxide and bad breath.

In general, a conventional mask covers the respiratory tract, such as the nose and mouth, to block the inhalation of fine dust during activities. It prevents fine dust in the air from being inhaled through the nose and substances flying from the mouth. is formed

Most of these masks are made of a sheet of fiber material for easy portability or are equipped with a filter of a simple structure on the sheet.

In addition, masks have been mainly worn by cold patients, people with respiratory diseases, or people who are particularly sensitive to cold air, but the number of users has increased due to the yellow dust containing a lot of fine dust and heavy metals that has occurred in China since the 2010s. With the recent outbreak of viruses such as COVID-19, it has become a daily necessity for infection and prevention.

A typical mask structure generally consists of a mask pad made of breathable fabric to prevent significant discomfort in breathing, and earrings attached to both sides to be worn over the ears. Depending on the type and performance of the filter, a dental mask, KF 80 There are masks, KF 94 masks, KF 99 masks and N95 masks.

On the other hand, if you cough while wearing a mask or use the mask for a long time, problems such as bad breath or bacterial growth may occur, which results in poor long-term usability.

To solve this problem, masks designed to replace pads with deodorizing functionality are being developed, but they are expensive, have limitations in applying to disposable masks, and are inconvenient when used. This exists.

In addition, with conventional masks, when the flow rate and pressure of exhaled breath increase due to increased heart rate and breathing volume due to jogging, hiking, sports exercise, etc., the exhaled breath leaks out toward the upper part of the face, that is, toward the eyes and forehead, fogging up the glasses. There is a problem in that exhaled breath is discharged along the edge of the mask body, causing droplets to be discharged into the air in front of the face.

Therefore, there is a need for research and development of masks that are inexpensive, can discharge exhaled breath and droplets toward the chest under the wearer's chin, and can naturally discharge carbon dioxide and bad breath when breathing.

By directing discharge from both ends of the tail downward to the left and right sides of the chin, it is possible to prevent droplets from being released into the air in front of the face and fogging up glasses, and to prevent droplets from being released into the air in front of the face and from fogging up glasses. This product allows the wearer to breathe comfortably and feel a pleasant environment by quickly expelling carbon dioxide and bad breath.

To this end, the mask 1 according to an embodiment of the present invention may include at least one of a mask body portion 10, a fixing band 20, a close contact portion 30, and an exhalation discharge portion 40. You can.

The mask body portion 10 is placed on the face to cover the wearer's nose and mouth.

The mask body portion 10 is formed to have a concave cross-sectional shape to accommodate the wearer's nose and mouth.

That is, the mask main body 10 is formed as a whole in a semi-circular or semi-elliptical shape with an empty interior, so that it has an accommodating space for accommodating the nose and mouth.

Also, when the central portion of the mask body 10 is cut in a horizontal cross-section, the inner shape may be one of a semicircular shape, a 'U' shape, and a 'V' shape.

At this time, the mask main body 10 is formed in a size so that its edges face the back of the user's nose, the nasolabial folds on both sides, both sides of the lips, and a certain area of the chin extending downward from both sides of the lips, respectively. The exhaled air contact area can be significantly reduced compared to a conventional general mask.

As a result, skin problems can be minimized by minimizing the contact area between the skin and harmful gases from exhaled breath (carbon dioxide generated from the lungs, stomach acid generated from the stomach).

A shape maintaining part 50 is installed vertically on the inner surface of the mask main body 10.

The shape maintaining portion 50 performs a framework or framework function so that the mask body portion 10 maintains the above-described shape.

The shape maintaining portion 50 is formed in a substantially curved shape to maintain the central portion of the mask main portion 10 protruding in front of the wearer.

For example, the shape maintaining part 50 may be installed only on the inner surface of the mask main body 10.

As another example, the shape maintaining part 50 may be disposed in a certain area of the mask main body 10 and a lower portion thereof may also be located on the inner surface of the main body 41, which will be described later.

At this time, it is revealed that the length of the shape maintaining portion 50 in the mask 1 according to an embodiment of the present invention is not limited and can be applied in various ways.

This shape maintaining portion 50 may be formed of silicone material that is harmless to the human body.

At this time, it should be noted that the material of the shape maintaining portion 50 in the mask 1 according to an embodiment of the present invention is not limited.

However, the material of the close contact part 30 is used as a material that does not cause trouble to the face.

The mask main body 10 may be formed of a single material or may be made of a fiber material, and may be composed of an outer shell that is exposed to the outside and an outer shell that covers the user's nose and mouth while contacting the user's skin.

Therefore, when the wearer breathes while wearing the mask 1, the exhaled breath is mainly directed toward the inner surface of the mask main body 10.

The inner surface of the mask main body 10 may further include a filter sheet (not shown) to filter out contaminants such as fine dust, ultrafine dust, infectious bacteria, cold bacteria, and pathogens.

The filter sheet can be made of filter materials used in general masks such as KF94 and KF80.

Additionally, a plurality of nose supports 60 are installed on the upper inner surface of the mask main body 10 to be spaced apart from each other in the horizontal or circumferential direction and are seated on the wearer's nose.

Furthermore, since the additional close contact portion 70 has a certain weight, it maintains the lower part of the mask main body 10 in a shape that matches the curve of the wearer's chin.

Through this additional close contact portion 70, the lower part of the mask body 10 can be prevented from being separated from the wearer's chin, and external air can be prevented from penetrating into the interior through the lower side of the mask body 10. .

The nose support portion 60 and the additional close contact portion 70 may be made of silicone or other materials that are harmless to the human body.

The fixing band 20 is made of an elastic material so that its length can be varied to correspond to the size of the wearer's face or head.

The fixation band 20 according to an embodiment of the present invention includes variable features so that it can be selectively fixed to the wearer's ears or head.

For this purpose, the fixing band 20 may include a first elastic string 21, a second elastic string 22, a first button portion 23, and a second button portion 24.

The first elastic string 21 may be formed integrally at the center of one side of the mask main body 10.
The second elastic string 22 may be integrally formed in the center of the other side of the mask main body 10.

At this time, the first elastic string 21 and the second elastic string 22 are formed in a horizontal direction on the mask main body 10 so that they can be fixed to the wearer's ears or head.

The first button portion 23 is disposed at a distance from each other between a first male button portion 231 disposed at one end of the first elastic string 21 and one end and the other end of the first elastic string 21. It may include a plurality of first arm button portions 232.

The second button portion 24 is disposed at a distance from each other between a second male button portion 241 disposed at one end of the second elastic string 22 and one end and the other end of the second elastic string 22. It may include a plurality of second arm button portions 242.

When the first male button part 231 is bound to one of the first female button parts 232 and the second male button part 241 is bound to one of the second female button parts 242, the first male button part 231 is bound to one of the first female button parts 232. The elastic string 21 and the second elastic string 22 each form a loop to be hung around the wearer's ear.

At this time, the size of the loop formed by the first elastic string 21 is variable depending on the first female button part 232 to which the first male button part 231 is fastened, and the second male button part 241 is The size of the loop formed by the second elastic string 22 varies depending on the second arm button portion 242 that is fastened.

That is, when the first male button part 231 is bound to the first female button part 232 disposed in a position close to the mask main body 10 among the first elastic strings 21, the size of the ring is formed large, When the first male button portion 231 is fastened to the first female button portion 232 disposed at a position distant from the mask body portion 10, the size of the ring is formed to be relatively small.

Likewise, when the second male button part 241 is bound to the second female button part 242 disposed close to the mask main body part 10 among the second elastic strings 22, the size of the ring is formed large, and the mask When the second male button portion 241 is fastened to the second female button portion 242 disposed at a position distant from the main body portion 10, the size of the ring is formed to be relatively small.

Therefore, the wearer can adjust the binding positions of the first male button portion 231 and the first female button portion 232 and the second male button portion 241 and the second female button portion 242 according to the size of the wearer's face and head. By adjusting, the size of the loop formed by the first elastic string 21 and the second elastic string 22 can be adjusted.

Furthermore, when the first male button portion 231 formed on the first elastic string 21 and the second female button portion 242 formed on the second elastic string 22 are bound, the first and second elastic strings are attached to the wearer. It forms a ring that wraps around the head and secures it.

In this case, a comfortable fit can be provided by preventing both ears of the wearer from being pressed by the first elastic strap 21 and the second elastic strap 22.

Furthermore, the first male button portion 231 may be applied in plural numbers and arranged at least one between the first female button portions 232.

In addition, the second female button portion 242 may also be applied in plural numbers and arranged at least one between the second male button portions 241.

In this case, the wearer can adjust the size of one ring formed by the first elastic string 21 and the second elastic string 22 to suit the size of the wearer's face and head.

Meanwhile, the close contact portion 30 is coupled along the edge of the mask body portion 10.

The close contact portion 30 is formed to have a constant length. Although it may vary depending on the size of the wearer's face, the close contact portion 30 generally contacts the wearer's nose, the area around the nose, the area around the mouth, and the chin.

Since the close contact portion 30 has a certain weight, it remains in contact with the wearer's face. This prevents the edge of the mask body 10 from being separated from the wearer's face and prevents outside air from penetrating into the inside of the mask body 10.

This close contact portion 30 may be made of silicone or other materials that are harmless to the human body.

At this time, it should be noted that the material of the close contact portion 30 in the mask 1 according to an embodiment of the present invention is not limited.

However, the material of the close contact part 30 is used as a material that does not cause trouble to the face.

The expiratory breath discharge unit 40 is configured to discharge the wearer's exhaled breath, allowing the wearer to breathe smoothly, and provide a comfortable environment for the wearer by discharging carbon dioxide and bad breath generated by the exhaled breath.

The exhalation discharge part 40 may include a main body part 41 and an edge part 42.

The body portion 41 and the edge portion 42 may be formed of the same material as the mask body portion 10.

The body portion 41 may be formed integrally with the mask body portion 10, or may be manufactured separately and then coupled to the exhalation discharge portion 40 by any one of sewing, low-frequency bonding, and high-frequency bonding.

The main body 41 has a structure that protrudes a certain length from the lower side of the mask main body 10.

It extends obliquely from the bottom of the mask main body 10 toward the wearer's chin.

Accordingly, the main body portion 41 covers a certain area of the wearer's chin.

The main body portion 41 is formed in a shape whose width and length gradually become narrower from the top to the bottom.

Accordingly, the main body portion 41 is formed to have a substantially inverted triangle cross-sectional shape.

The edge portion 42 extends obliquely from the bottom of the main body 41 in a direction away from the wearer's chin.

Accordingly, the edge portion 42 covers a certain area of the wearer's chin.

The edge portion 42 is formed to have a smaller cross-sectional area than the main body portion 41.

The edge portion 42 is formed in a shape whose width and length gradually become narrower from the top to the bottom.

Accordingly, the edge portion 42 is also formed to have a substantially inverted triangle cross-sectional shape.

The edge portion 42 extends obliquely from the bottom of the main body 41 in a direction away from the wearer's chin.

Accordingly, the edge portion 42 covers a certain area of the wearer's chin.

Both the main body portion 41 and the edge portion 42 have a concave cross-sectional shape, and an discharge passage 40a through which the wearer's exhaled breath is discharged is formed therein.

At this time, the discharge passage 40a of the main body 41 and the discharge passage 40a of the edge portion 42 are formed to be connected to each other.

Furthermore, the entire edge portion 42 is formed in a sharp shape.

As shown in FIG. 4, since the edge portion 42 is formed in a sharp shape, exhaled breath can be induced to be discharged through the edge portion 42 by Kutta-Condition.

Therefore, the wearer's exhaled breath moves downward along the inner surface of the mask main body 10 and then sequentially passes through the discharge passage 40a of the main body 41 and the discharge passage 40a of the edge portion 42, It is discharged through the bottom of the edge portion 42.

At this time, as a result of the experiment performed by the applicant of the present invention after wearing the mask (1), it was confirmed that the exhaled breath passed through the chin and was discharged toward the neck.

By implementing the mask 1 in this way, exhaled breath and carbon dioxide can be immediately discharged to the outside of the mask main body 10 every time one exhales. This can prevent the wearer from smelling his or her own breath. Ultimately, the wearer can feel comfortable when wearing the mask 1.

Moreover, both the main body portion 41 and the edge portion 42 may be formed to have a width length of approximately 20 to 30% of the width length of the mask main portion 10. In addition, the close contact portion 30 is not coupled to the main body portion 41 and the edge portion 42. Accordingly, the main body portion 41 and the edge portion 42 are lighter than the mask body.

Accordingly, the main body portion 41 and the edge portion 42 are probabilistically spaced apart from the wearer's chin by exhaled breath when the wearer exhales.

That is, when the wearer exhales strongly above a certain pressure, the expiratory breath outlet 40 momentarily flutters and is spaced apart from the wearer's chin, creating an empty space between the exhaled breath outlet 40 and the chin.

In this case, exhaled breath, carbon dioxide, and bad breath can be discharged more efficiently.

Of course, when the wearer inhales, the exhalation discharge unit 40 returns to its original position under its own weight and remains in contact with the chin to prevent the inflow of external air.

Furthermore, as described above, a certain area on the lower side of the mask body 10 faces the corners of the mouth on both sides of the wearer's lips, and the exhalation discharge portion 40 is disposed on the lower side of the mask body 10, allowing the wearer to The exhaled breath that is generated is lowered through the corner of the mouth by the lower side of the mask main body (10) and then discharged only through the exhaled breath discharge unit (40).

In this case, during activities such as jogging, hiking, and sports, when the flow rate and pressure of exhaled breath increase due to an increase in heart rate and breathing volume, the exhaled breath outlet 40 functions as a kind of check valve, and during normal breathing and rapid breathing, As shown in Figure 4, the flow of exhalation is induced.

In other words, since exhaled breath is discharged downward only through the exhaled breath discharge unit 40, it is possible to prevent exhaled breath from being discharged toward the eyes or forehead, such as preventing glasses from fogging. In particular, the exhaled exhaled breath is primarily directed to the upper chest of the wearer. It can reduce droplet dispersion in the air by contact with it.

A person skilled in the art to which this invention belongs will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive. The scope of the present invention is indicated by the scope of the patent claims described later rather than the detailed description above, and all changes or modified forms derived from the meaning and scope of the claims and their equivalent concepts are included in the scope of the present invention. must be interpreted.
