Description

Shaving blade and shaver for improving skin feel

Technical Field

The invention relates to a shaving tool, in particular to a shaving blade capable of improving skin feel and a shaving tool using the same.

Background

In order to facilitate the hair cutting by the shaving blade, one end of the existing shaving blade is provided with a plurality of cutter teeth which are arranged at intervals, and the hair is cut by utilizing the cutting edge arranged on the edge of the cutter teeth. In order to ensure the shaving effect and control the production cost, the thickness of the existing shaving blade is relatively thin and is generally less than 2mm, so that the corresponding cutter teeth at the end part of the shaving blade are relatively sharp, the cutter teeth are easy to stab the skin when in use, and certain potential safety hazards exist, particularly for hair trimming of infants.

CN113815022A discloses a cutter head structure for hair clipper and hair clipper, which adopts the technical scheme that an isolation structure is additionally arranged between a hair-cutting blade and skin, a convex second connecting part is arranged at the end of the isolation structure, and the bottom surface and the end surface of a cutter tooth are separated from the skin by using the first connecting part and the second connecting part, so as to avoid the cutter tooth from stabbing the skin in the using process and improve the use safety of the hair clipper.

Although the structure can avoid the skin stabbing by the cutter teeth when in use, the material cost and the assembly cost of the hair clipper are increased because an additional isolation structure is required; second, the addition of the spacer structure and the thickness of the razor blade necessarily increases the distance between the razor blade and the skin, making the hair clipper unable to accommodate the cutting requirements of short hair (also known as hair cut or cut).

Detailed Description

Embodiments of the invention are further described below with reference to the accompanying drawings:

as shown in fig. 1 to 4, the present invention is a skin-feel-improving razor blade comprising a substrate 1 made of a metal or ceramic material; the substrate 1 is provided with a skin-contacting working surface 11 and a cutting working surface 12 matched with the movable blade; the cutter teeth 2 are arranged at one end of the substrate 1, and the hair guide grooves 3 between the cutter teeth 2 penetrate through the skin adhering working surface 11 and the cutting working surface 12. Therefore, hairs can conveniently enter the hair guide grooves 3 in the middle of the cutter teeth 2, and when the movable cutter swings back and forth along the cutting working surface 12 of the substrate 1, the hairs entering the hair guide grooves 3 can be trimmed. When viewed from any side direction perpendicular to the cutting working surface 12 from both sides of the substrate 1 (namely, any orthographic projection direction of both sides of the substrate 1), a processing groove 4 is arranged at one end of the cutting working surface 12 and the skin-contacting working surface 11 of the substrate 1, which are provided with the cutter teeth 2, so that bosses 5 higher than at least partial surfaces of the cutter teeth 2 are respectively formed at the end parts of the cutter teeth 2, and the edges of the bosses 5 are smoothly processed. The rounding treatment is to round the edges of the end parts of the boss 5 and the cutter tooth 2 to ensure that the edges of the end parts of the boss 5 and the cutter tooth 2 generate a smoothing effect, so that the skin is prevented from being scratched when the boss 5 and the cutter tooth 2 are in contact with the skin, and the comfort when the cutter tooth 2 is in contact with the skin is improved. The processing groove 4 is additionally arranged at one end of the cutter tooth 2 arranged on the substrate 1, so that the end parts of the cutter teeth 2 of the skin sticking working surface 11 and/or the cutting working surface 12 respectively form a boss 5 with the edge for smooth processing, the boss 5 can be utilized to play a role in protection, the skin is prevented from being punctured by the end part of the cutter tooth 2 when the shaver is used, and the use safety of the shaver blade is improved. In addition, when in use, the lug bosses 5 at the end parts of the cutter teeth 2 can also play a role similar to a comb, stimulate cranial nerves, accelerate the blood circulation of the skin of the head and the blood oxygen supply, thereby generating more comfortable skin feeling and improving the use comfort of the razor blade.

Secondly, because the protection structure of the end part of the existing cutter tooth 2 is basically an independent plastic structure, such as the plastic isolation structure disclosed in CN113815022A, not only the production cost is increased, but also additional assembly is required, and when in use, the protection structure and the end part of the cutter tooth 2 have a fit gap, and hairs are easily clamped into the fit gap to generate a hair-plucking phenomenon, which causes skin pricking feeling in the hair trimming process. The processing groove 4 is utilized to form the lug boss 5 at the end part of the cutter tooth 2 on the skin attaching working surface 11 and/or the cutter tooth 2 of the cutting working surface 12 of the substrate 1, so that the production and the processing are convenient, the assembly clearance can be effectively reduced, the hair pulling phenomenon of the shaving blade in use is avoided, and the use comfort of the shaving blade in hair trimming is improved.

In the hair trimming process, only the skin-close working surface 11 is contacted with the skin of the head in most cases, so that the skin feeling during hair trimming is improved, and the comfort is improved; the processing groove 4 is arranged on the skin-close working surface 11 of the substrate 1, so that the boss 5 at the end part of the cutter tooth 2 is higher than at least part of the upper surface of the cutter tooth 2, and the edge of the boss 5 is subjected to smoothing treatment. The processing groove 4 is arranged on the skin-close working surface 11 of the substrate 1, so that the end parts of the cutter teeth 2 form the bosses 5, and when the razor is used, the bosses 5 at the end parts of the cutter teeth 2 can play a role similar to a comb to stimulate cranial nerves, accelerate blood circulation and blood oxygen supply of cranial skin, generate more comfortable skin feeling and improve the use comfort of the razor blade.

In order to make each cutter tooth 2 at one end of the razor blade play the roles of stimulating cranial nerves and improving skin feel when in use, the height H1 of the lug boss 5 at the end part of each cutter tooth 2 is more than one third of the thickness H2 of the end part of each cutter tooth 2. The distance H2 between the highest point of the boss 5 at the end of each cutter tooth 2 and the cutting face 12 (i.e., the thickness H2 at the end of the cutter tooth 2) is one quarter to three quarters of the thickness T1 of the base sheet 1, based on the cutting face 12 of the base sheet 1. In practice, the thickness H2 of the end of cutter tooth 2 depends on the thickness T1 of the substrate 1. For example, when the substrate 1 is made of a plate material having a thickness of 2mm, in order to ensure the working strength of the cutter tooth 2, the thickness H2 of the end portion of the cutter tooth 2 may be set to be half of the thickness T1 of the substrate 1. At the moment, the height H1 of the lug boss 5 can be two thirds of the thickness H2 of the end part of the cutter tooth 2, so that the working strength of the cutter tooth 2 is ensured, the stimulation of the lug boss 5 to cranial nerves is improved to the maximum extent, the skin feeling of the razor blade when contacting with the skin is improved, and the use comfort of the shaver is improved. Of course, when the base sheet 1 has a thickness T1 greater than 4mm, the thickness H2 of the end portion of the cutter tooth 2 may be set to be one-fourth or more than one-fourth and less than three-fourth of the thickness T1 of the base sheet 1, and the height H1 of the boss 5 may be selected to be one-third or two-thirds of the thickness H2 of the end portion of the cutter tooth 2, in consideration of the combined requirements of cutting short hairs and stimulating cranial nerves by the boss 5. Therefore, the shaving blade can meet the requirement of short hair trimming, and meanwhile, the stimulation of the lug boss 5 to the cranial nerves is improved, and the skin feeling of the shaving blade contacting with the skin in the hair trimming process is improved. In summary, the arrangement is such that the thickness H2 of the end portion of the cutter tooth 2 and the height H1 of the boss 5 can be set smaller as the thickness T1 of the base sheet 1 is larger. When the thickness T1 of the substrate 1 is smaller, the end thickness H2 of the cutter tooth 2 can be correspondingly increased to improve the working strength of the cutter tooth 2, and the height H1 of the corresponding boss 5 can also be set to be relatively larger to improve the stimulation of the boss 5 to the cranial nerve and improve the skin feel. The specific set value may depend on the actual thickness of the substrate 1.

In order to facilitate the production and processing of the bosses 5 at the end parts of the cutter teeth 2, the processing grooves 4 penetrate through two sides of the skin attaching working surface 11 of the substrate 1, so that the bosses 5 are respectively formed at two sides of the skin attaching working surface 11 of the substrate 1 and the end parts of the cutter teeth 2. The processing groove 4 penetrates through the two sides of the skin attaching working surface 11 of the substrate 1, so that the bosses 5 can be formed on the two sides of the substrate 1 and the end parts of the cutter teeth 2 at one time, the processing and forming of the bosses 5 are greatly facilitated, and the production cost is reduced. If the processing grooves 4 are provided only on the upper surface of each cutter tooth 2, the difficulty of processing the end bosses 5 of the cutter teeth 2 is increased virtually, and therefore, it is preferable that the processing grooves 4 penetrate both sides of the substrate 1.

In order to facilitate the processing and forming of the boss 5, improve the production efficiency and reduce the production cost, the processing groove 4 is formed by processing at least a first processing surface 41 and a second processing surface 42, the first processing surface 41 enables one end of the skin attaching working surface 11 of the substrate 1, which is provided with the cutter teeth 2, to be inclined, and the thicknesses of the substrate 1 and the cutter teeth 2 are gradually reduced from thickness to thickness; the first processing surface 41 can be formed by adopting machining processes such as stamping, cutting and the like, and the technical scheme preferably adopts the stamping process to form the inclined surface and the cutter teeth 2 on one end of the substrate 1 at one time, so that the production benefit of the shaving blade is improved. The second processing surface 42 is formed by a grinding process, namely, on the basis of the first processing surface 41, processing grooves 4 are formed on two sides of the substrate 1 and the upper surfaces of the cutter teeth 2 by the grinding process, so that bosses 5 are formed on two sides of the substrate 1 and the end parts of the cutter teeth 2, and the edges of the bosses 5 are rounded and smoothed, so that not only can the skin be prevented from being scratched by the bosses 5, but also the bosses 5 on the end parts of the cutter teeth 2 can generate an effect similar to a comb, the cranial nerves are stimulated, the blood circulation and the blood oxygen supply of the cranial skin are accelerated, the more comfortable skin feeling is generated, and the use comfort of the razor blade is improved. Because the end of the substrate 1, which is provided with the cutter teeth 2, is inclined, when the shaver blade is used, the cutter teeth 2 inclined on the substrate 1 can be easily inserted into hair clusters, and the fitting degree with the skin of the head is better, so that the bosses 5 at the end parts of the cutter teeth 2 can be only locally higher than the upper surfaces of the cutter teeth 2. Of course, the end of the substrate 1 where the cutter teeth 2 are provided may be flat, and the processing groove 4 may be square, as shown in fig. 5, but with this structure, the skin contact working surface 11 of the razor blade is relatively poor in the adhesion with the skin of the head, and therefore, the embodiment of the present embodiment is a preferred embodiment.

In hair trimming, a pair of hair clippers is often held in a reverse direction at specific parts such as sideburns or hindbrains, and the hair-pegs on the surface of the skin are shaved off by lightly shaving the sideburns or the hindbrains with a razor blade. In order to prevent skin from being scratched, the front end edge of each cutter tooth 2 of the cutting working surface 12 of the substrate 1 and the front end edge of the substrate 1 are respectively provided with an arc chamfer 6. Through the arc chamfer 6, the sharpness of the side face of one end of the substrate 1, which is provided with the cutter teeth 2, can be eliminated, and when the hair is finely trimmed, the skin can be effectively prevented from being scratched, and the use safety of the shaver is improved.

Second embodiment

On the basis of the above technical solutions, the applicant has also proposed another technical solution, as shown in fig. 6 to 10, as seen from either side of the substrate 1 perpendicular to the cutting working surface 12, machining grooves 9 are respectively provided at one ends of the cutting working surface 12 and the skin adhering working surface 11 of the substrate 1 where the cutter teeth 2 are provided, so that an inner boss 7 and an outer boss 8 higher than at least partial surfaces of the cutter teeth 2 are respectively formed at the end portions of the cutter teeth 2 on the cutting working surface 12 and the skin adhering working surface 11, and the edges of the inner boss 7 and the outer boss 8 are both smoothly processed. The upper surface and the lower surface of the end part of the cutter tooth 2 are respectively formed with an inner boss 7 and an outer boss 8 and are smoothened by respectively additionally arranging a processing groove 9 on a skin attaching working surface 11 and a cutting working surface 12 of one end of the substrate 1 provided with the cutter tooth 2. When hair is normally cut, the inner bosses 7 at the ends of the cutter teeth 2 on the skin-close working surface 11 can play a comb-like effect, stimulate cranial nerves, accelerate blood circulation and blood oxygen supply of cranial skin, so that more comfortable skin feeling is generated, and the use comfort of the razor blade is improved. When the hair is refined on special parts such as temples and the neck of the back brain, the outer bosses 8 formed at the ends of the cutter teeth 2 of the cutting working surface 12 can also be directly contacted with the skin, which also has the effect similar to a comb, stimulates the nerves of the head, accelerates the blood circulation and blood oxygen supply of the skin of the head, thereby generating more comfortable skin feeling and improving the use comfort of the shaving blade.

In the actual production process, the machined groove 9 of the inner boss 7 is formed by machining the first machined surface 41 and the second machined surface 42, the first machined surface 41 is formed by a pressing process, and the second machined surface 42 is formed by a grinding process, as in the first embodiment. The processing groove 9 of the outer boss 8 is also processed by a grinding process, and the stamping process and the grinding process are the existing mature processes and are not described in detail here.

In order to ensure the hair finishing effect on special parts such as temple or hindbrain, the height H4 of the outer boss 8 arranged at the end of each cutter tooth 2 of the cutting working surface 12 is less than or equal to the height H5 of the inner boss 7 arranged at the end of each cutter tooth 2 of the skin-adhering working surface 11. Because the hair clipper is mainly used reversely in the process of fine trimming the hair, the cutting working surface 12 of the hair shaving blade is contacted with the skin of the head, so that the height of the outer lug boss 8 is set to be less than or equal to the height of the inner lug boss 7 in order to ensure the fine trimming effect of the hair at special parts such as temples or the back neck, when the fine trimming process is carried out, the outer lug boss 8 can be directly contacted with the skin at the temples or the back neck, the cranial nerves are stimulated, the skin feeling is improved, meanwhile, the hair pile at the temples or the back neck can be removed to the maximum degree, and the fine trimming effect is improved. If the outer bosses 8 are higher than the inner bosses 7, the skin feel can be improved, but the corresponding piles are blocked by the outer bosses 8 and are not easy to shave off, and the purpose of fine trimming cannot be achieved, so the embodiment of the embodiment is a preferred embodiment.

To ensure the hair-conditioning effect, the distance H4 between the highest point of the outer projections 8 and the cutting face 12 (also referred to as the height of the outer projections 8) is less than or equal to half the thickness T2 of the base sheet 1, based on the cutting face 12 of the base sheet 1. The specific setting rule is that the proportion of the height H4 of the outer boss 8 to the thickness T2 of the substrate sheet 1 is smaller as the thickness T2 of the substrate sheet 1 is thicker; and the smaller the thickness T2 of the base sheet 1, the greater the proportion of the height H4 of the outer projections 8 to the thickness T2 of the base sheet 1. For example, when the thickness T2 of the base sheet 1 is greater than or equal to 4mm, the height H4 of the outer projections 8 is preferably one-fourth of the thickness T2 of the base sheet 1; and when the thickness T2 of the base sheet 1 is less than or equal to 2mm, the height H4 of the outer projections 8 is preferably half of the thickness T2 of the base sheet 1. The specific configuration may be determined according to the material or thickness of the substrate 1, and the embodiment is not further limited.

To improve the comfort and skin feel of the razor blade during use, the distance H3 between the highest point of the inner projections 7 and the highest point of the outer projections 8, viewed in either direction perpendicular to the cutting face 12 from both sides of the base sheet 1, is one quarter to three quarters of the thickness T2 of the base sheet 1. The specific arrangement rule is that the distance H3 between the outer boss 8 and the inner boss 7 is correspondingly larger as the thickness T2 of the substrate 1 is thicker. When the thickness T2 of the substrate 1 is thinner, the distance H3 between the outer projection 8 and the inner projection 7 is also reduced. For example, when the thickness T2 of the substrate sheet 1 is 4mm or more, the distance H3 between the outer projections 8 and the inner projections 7 is one quarter to two halves of the thickness T2 of the substrate sheet 1. When the thickness T2 of the substrate 1 is less than or equal to 2mm, the distance H3 between the outer boss 8 and the inner boss 7 is half to three quarters of the thickness T2 of the substrate 1, so that the stimulation of the outer boss 8 and the inner boss 7 to cranial nerves is improved while the hair cutting effect is ensured, and the skin feel of the razor blade when contacting with the skin is improved. The specific configuration may be determined according to the material or thickness of the substrate 1, and the embodiment is not further limited.

On the basis of the razor blade described above, the applicant has also proposed a razor solution including the skin-feel-enhancing razor blade described in any one of the above.

The above examples should not be construed as limiting the present invention, but any modifications made based on the spirit of the present invention should be within the scope of protection of the present invention.
