Description

Technical Field

[0001] This invention relates to a hair trimming device, and more specifically to a hair-entry hole structure for a trimming blade, primarily applicable to trimming tools such as razors, hair removers, or lint removers. Background Technology

[0002] The outer surface of the static blade used in razors, epilators, or lint removers that comes into contact with the skin is generally a smooth plane or a slightly curved sphere. While this structure can improve the smoothness of the static blade as it glides along the skin surface, the smoothness or spherical shape also affects the ability of the static blade to capture some hairs, such as beard hairs, that are close to the skin surface. These hairs cannot be easily captured by the static blade and cannot enter the hair follicles within the blade. As a result, the hairs cannot be cut, which relatively reduces the hair trimming performance and trimming effect of the static blade. Summary of the Invention

[0003] To solve the above technical problems, this invention provides a hair-entry pore structure for the trimming blade. By improving the hair-entry pore structure, it can effectively ensure that the static blade lifts up and captures hairs such as beards that are close to the skin surface when it slides along the skin, thereby improving the hair trimming performance and effect of the static blade.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is a hair inlet structure for trimming blades, including a substrate, in which an X-axis and a Y-axis are formed, the X-axis and the Y-axis intersect to form an origin o, and hair inlets penetrating the substrate are provided with the origin o as a reference, and a number of trimming areas with hair inlets are formed in an array of X-axis and Y-axis.

[0005] In the trimming area, except for the outermost pores, any pore is surrounded by cobonded edges of different thicknesses. The number of cobonded edges is even, forming at least a supporting cobond and an adjacent and connected scraping cobond. The supporting cobond is recessed or raised along the outer surface of the substrate, such that the thickness of the supporting cobond is less than or greater than the thickness of the scraping cobond.

[0006] Preferably, the support cobonding is formed at the junction of any three adjacent pores.

[0007] Preferably, at least two supporting cobonds are formed around the same pore, and the at least two supporting cobonds and the shaving cobonds are alternately arranged.

[0008] Preferably, a spherical protrusion is provided on the supporting cobond, the diameter of which is smaller than the width of the supporting cobond, and its highest point is lower than or higher than the outer surface of the substrate.

[0009] Preferably, the thickness of the cobonded surface is less than or equal to the thickness of the substrate.

[0010] Preferably, an annular groove is provided at the edge of each pore on the inner surface of the substrate, and the depth of the annular groove is less than the thickness of the substrate.

[0011] Preferably, a protruding spherical point is provided on the bottom surface of the annular groove on the inner surface of the substrate, and the spherical point does not extend beyond the inner surface of the substrate.

[0012] Preferably, in the substrate, with the origin o as the reference, a number of pores are arranged coaxially and spaced along the X and Y axes to form a trimming area for the pores; in the trimming area, except for the outermost pores, each pore is surrounded by four bonded edges.

[0013] Among them, the four cobonded edges are two staggered support cobonds and scraped cobonds. The thickness of the support cobond is less than the thickness of the scraped cobond, and the thickness of the scraped cobond is less than or equal to the thickness of the substrate.

[0014] Preferably, in the substrate, with the origin as the reference, a number of pores are arranged alternately and staggered on the X and Y axes to form a trimming area for a number of pores; in the trimming area, except for the outermost pores, each pore is surrounded by six common bonds.

[0015] Among them, there are six cobonded edges with three staggered supporting cobonds and scraped cobonds. The thickness of the supporting cobonds is less than the thickness of the scraped cobonds, and the thickness of the scraped cobonds is less than or equal to the thickness of the substrate.

[0016] Preferably, in the substrate, with the origin o as the reference, a number of pores are arranged alternately and staggered on the X and Y axes to form a trimming area for a number of pores; in the trimming area, except for the outermost pores, each pore is surrounded by twelve bonded edges.

[0017] Among them, six staggered support cobonding and scraping cobonding are formed in the twelve cobonding edges. The thickness of the support cobonding is less than the thickness of the scraping cobonding, and the thickness of the scraping cobonding is less than or equal to the thickness of the substrate.

[0018] Preferably, the co-bonded thickness of multiple shavings within the trimming area is the same or different.

[0019] Preferably, the pores are one of the following shapes: round, triangular, square, rhomboid, hexagonal, or irregular.

[0020] The beneficial effect of this invention is that by setting the number of cobonded edges to an even number and making the thicknesses of adjacent and connected cobonded edges different, when the cobonded edges surround to form a hair inlet, at least two types of supporting cobonds and hair-shaving cobonds with different functions and effects are formed around the hair inlet. Furthermore, a stepped structure with a height difference is formed between the supporting cobonds and the hair-shaving cobonds. Because the skin has a certain degree of elasticity, when the static blade contacts the skin, the skin will indent inward. At this time, the stepped structure with a height difference between the supporting cobonds and the hair-shaving cobonds can slide along the skin surface, shaving up the hair that is close to the skin surface, thereby achieving the hair-shaving effect and improving the hair inlet efficiency and hair trimming effect of the static blade.

[0035] To make the technical objectives, technical solutions, and technical effects of the present invention clearer, the following will be described in conjunction with the appendix. Figures 1-14 Specific embodiments of the present invention will be described in further detail so that those skilled in the art can implement or use the present invention.

[0036] This invention relates to a hair inlet 2 structure for a trimming blade, comprising a substrate 1. An X-axis and a Y-axis are formed at the center of the substrate 1 in both its length and width directions. The X-axis is horizontal, and the Y-axis is vertical. The intersection of the X-axis and Y-axis is the origin o. During production, the stationary blade has a hair inlet 2 penetrating the substrate 1, with the origin o as a reference. During use, when the stationary blade slides along the skin surface, the hair to be trimmed, such as beard hair, can extend into the hair inlet 2. Then, a moving blade (not shown in the figure), mounted below the stationary blade, moves along the stationary blade under the drive mechanism and cuts the hair inserted into the stationary blade, thus trimming the beard hair.

[0037] To improve the trimming efficiency of beard and other hairs, in actual production, the hair inlet 2 is arranged in an array along the X and Y axes with the origin o as the reference, thus forming a hair trimming area in the substrate 1. The trimming area will vary depending on the application of the static blade. For example, when the static blade is used in a rotary shaver, epilator, or lint remover, the trimming area will be circular; while when the static blade is used in a reciprocating shaver, epilator, or other trimming tools, the trimming area will be mostly square, and the size of the trimming area will be smaller than the size of the substrate 1.

[0038] To address the technical problem that existing static blades fail to capture hairs such as beards that are close to the skin surface when sliding along the skin, thus affecting the hair trimming performance and effect, a new method is proposed: In the trimming area, excluding the outermost hair inlet pores 2, each hair inlet pore 2 is surrounded by a cohesive edge 3 of varying thickness. Since the hair inlet pores 2 are arranged at intervals along the X and Y axes, any two adjacent hair inlet pores 2 in any direction on the substrate 1 will necessarily have a cohesive edge 3 (a cohesive edge 3 refers to a solid edge shared by two adjacent hair inlet pores 2).

[0039] To effectively shave off hairs such as beards that are close to the skin surface, the number of cobonded edges 3 is even (or can be understood as an even number), forming at least supporting cobonds 31 and adjacent, connected shaving cobonds 32. The supporting cobonds 31 are recessed or raised along the outer surface of the substrate 1, such that the supporting cobond thickness t1 is less than or greater than the shaving cobond thickness t2. By setting the number of cobonded edges 3 to even and making the thicknesses of adjacent, connected cobonded edges 3 different, when the cobonded edges 3 surround a hair follicle 2, the hair follicle 2 is surrounded by supporting cobonds 31 and shaving cobonds 32 with at least two functions and roles. Furthermore, a stepped structure 33 with a height difference is formed between the supporting cobonds 31 and the shaving cobonds 32. Because the skin has a certain degree of elasticity, when the static blade comes into contact with the skin, the skin will indent inward. At this time, the step structure 33, which forms a height difference between the supporting cobond 31 and the shaving cobond 32, can slide along the skin surface and shave the hair that is close to the skin surface, thereby achieving the shaving effect and improving the hair entry efficiency and hair trimming effect of the static blade.

[0040] In specific implementation, regardless of whether the supporting cobond 31 is recessed or raised along the surface of the substrate 1, as long as a stepped structure 33 with a height difference is formed between the supporting cobond 31 and the roughened cobond 32, no further limitation is made in this application.

[0041] When trimming a beard, the user holds the razor and slides the stationary blade along the skin surface in any direction. When the support bond 31 is formed at the junction of any three adjacent hair follicles 2, as... Figure 3 , 6 As shown in Figures 9 and 12, the stepped structure 33 formed by the height difference between the shaving cobond 32 and the supporting cobond 31 can face multiple different directions. Furthermore, when the hair to be trimmed, such as beard hair, is close to the skin, the orientation of the hair has a large degree of randomness. When the static blade slides along the skin surface in any direction, the stepped structure 33 in at least one direction can shave off the hair close to the skin surface, without being limited by the single direction of the stepped structure 33, thereby improving the hair-feeding efficiency of the static blade and the hair trimming effect.

[0042] To improve hair removal efficiency, at least two supporting cobonds are formed around the same hair inlet pore, and at least two supporting cobonds 31 and hair removal cobonds 32 are alternately arranged. Since the thickness t2 of the hair removal cobond is greater than the thickness t1 of the supporting cobond, the hair removal cobonds 32 are used to separate the supporting cobonds 31, so that a continuous edge of the same or adjacent hair inlet pore 2 is not made up of thin supporting cobonds 31. Setting the hair removal cobonds 32 between two adjacent supporting cobonds 31 can improve the working strength of a continuous edge of the same or adjacent hair inlet pore 2, and avoid the hair inlet pore 2 being excessively twisted under force, thus affecting the hair removal efficiency. At the same time, the multiple supporting cobonds 31 are arranged alternately. Due to the limitation of the cross-sectional shape of the hair inlet pore 2, the stepped structure 33 between the supporting cobonds 31 and the hair removal cobonds 32 can be arranged in a preset direction and angle as needed, so as to ensure that when the static blade slides along the skin in any direction and at any angle, it can remove the hair such as beard that is close to the skin surface. For specific examples, please refer to the specific embodiments listed below.

[0043] like Figure 13 As shown, to improve the skin feel and user comfort when using the static razor, protruding spherical bumps 4 are provided on the support cobond 31. The diameter of the spherical bumps 4 is smaller than the width of the support cobond 31, and its highest point is lower than or higher than the outer surface of the substrate 1. By setting spherical bumps 4 with a diameter smaller than the width of the support cobond 31 on the plane of each thin support cobond 31, the spherical bumps 4 will not fill the stepped structure 33 that forms a height difference between the support cobond 31 and the shaving cobond 32. When the static razor slides along the skin surface, the spherical bumps 4 can push and flatten the skin, making it easier for the stepped structure 33 to shave the hair close to the skin surface, thus improving the hair entry efficiency and hair trimming effect of the static razor.

[0044] In actual processing, the highest point of the spherical protrusion 4 can be lower than the outer surface of the substrate 1. Alternatively, the highest point of the spherical protrusion 4 can be set to extend beyond the outer surface of the substrate 1. Regardless of whether the highest point of the spherical protrusion 4 is lower or higher than the outer surface of the substrate 1, the spherical protrusion 4 can fill the space lost due to the reduced thickness of the supporting bond 31. When the scalpel slides along the skin surface, the spherical protrusion 4 can push and flatten the skin, and the directional step structure 33 will lift the hair closest to the skin surface, improving the hair removal and trimming efficiency of the scalpel. Furthermore, the spherical surface of the spherical protrusion 4 can improve the smoothness of the scalpel sliding along the skin surface, thereby improving the skin feel and comfort of using the scalpel.

[0045] In some specific embodiments, for example, the thickness of the shaving cobond t2 is less than or equal to the thickness of the substrate 1, preferably the thickness of the shaving cobond t2 is the same as the thickness of the substrate 1. In this way, only one step structure 33 is formed between the shaving cobond 32 and the support cobond 31, which facilitates the removal of hair close to the skin surface by the static blade when it slides along the skin surface. Of course, setting the thickness of the shaving cobond t2 to be less than the thickness of the substrate 1 but greater than the thickness of the support cobond t1, so that a three-level step structure 33 is formed between the outer surface of the substrate 1, the shaving cobond 32 and the support cobond 31, can also achieve the shaving function of the static blade. However, due to the thinness of the substrate 1, it is generally less than 0.2 mm, which is not conducive to the production and processing of the three-level step structure 33. Therefore, the technical solution of setting the thickness of the shaving cobond t2 to be equal to the thickness of the substrate 1 is the preferred embodiment.

[0046] In the above embodiments, if the thickness t2 of the shaving cobonding is equal to the thickness of the substrate 1, spherical protrusions 4 can also be provided on the outer surface of the shaving cobonding 32. In this case, the highest point of the spherical protrusions 4 will exceed the outer surface of the substrate 1. When the static knife slides along the skin surface, the spherical protrusions 4 can not only ensure the smoothness of the static knife's sliding, but also improve the skin feel and enhance the comfort of using the static knife.

[0047] In the above embodiment, the thickness t2 of the hair removal cobonding is set to be less than the thickness of the substrate 1 but greater than the thickness of the support cobonding to form a three-stage stepped structure 33. At this time, the highest point of the spherical protrusion 4 set on the hair removal cobonding 32 can also be set not to exceed the outer surface of the substrate 1. In this way, when the static blade slides along the skin surface, the spherical protrusion 4 can push the skin and flatten the skin. The directional stepped structure 33 will lift the hair closest to the skin surface, improving the hair entry efficiency and hair trimming efficiency of the static blade.

[0048] like Figure 14 As shown, when the stationary blade slides along the skin surface, the hair or beard hair to be cut on the skin surface will enter the hair inlet 2 of the stationary blade. When the moving blade installed below the stationary blade swings or rotates along the stationary blade under the drive mechanism (not shown in the figure), due to the large inner surface area of ​​the stationary blade, the surface temperature of the stationary blade is relatively high under the action of frictional resistance between the moving blade and the stationary blade, which can easily cause the surface temperature of the stationary blade to be too high and burn the skin. In order to reduce the surface temperature rise of the stationary blade, annular grooves 5 are provided at the edges of each hair inlet 2 on the inner surface of the substrate 1, and the depth of the annular grooves 5 is less than the thickness of the substrate 1. By providing annular grooves 5 around each hair inlet 2 on the inner surface of the stationary blade, the contact area of ​​the moving blade when it swings or rotates along the stationary blade is relatively reduced. With the reduction of the contact area, the frictional resistance between the moving blade and the stationary blade will also be relatively reduced, thereby achieving the purpose of reducing the surface temperature rise of the stationary blade, avoiding excessive surface temperature rise of the stationary blade and burning the skin, and improving the comfort of using the stationary blade.

[0049] To enhance the working strength of each pore 2 in the static blade and prevent distortion when the static blade contacts the skin, a protruding ball point 51 is provided on the bottom surface of the annular groove 5 on the inner surface of the substrate 1. This ball point 51 does not extend beyond the inner surface of the substrate 1. By providing the protruding ball point 51 in the annular groove 5, and ensuring that the highest point of the ball point 51 does not extend beyond the inner surface of the substrate 1, the moving blade will not contact the ball point 51 during use, thus not increasing the frictional resistance between the moving and static blades. Simultaneously, the ball point 51 relatively increases the connection strength on both sides of the annular groove 5, effectively preventing distortion of the pore 2 when the static blade contacts the skin and improving the working stability of the static blade. In practice, multiple ball points 51 can be provided in the annular groove 5, for example, evenly arranged around the perimeter of the pore 2, to maximize the working strength of the static blade.

[0050] Several inlet holes 2 are provided in the stationary blade. To improve the inlet efficiency of the stationary blade, the inlet holes 2 are arranged in different ways. Different arrangements will result in the inlet holes 2 being surrounded by a different number of cobonded edges 3, for example:

[0051] Example 1

[0052] like Figures 1-3 As shown, in the substrate 1, with the origin o as the reference, a number of pores 2 are arranged coaxially and spaced along the X and Y axes to form a trimming area. When the pores 2 in the substrate 1 are arranged coaxially and spaced along the horizontal and vertical axes, in order to ensure the shaving effect, in the trimming area, except for the outermost pores 2, each pore 2 is surrounded by four cobonded edges 3. Among them, two staggered support cobonds 31 and shaving cobonds 32 are formed in the four cobonded edges 3. The thickness t1 of the support cobond is less than the thickness t2 of the shaving cobond, and the thickness t2 of the shaving cobond is less than or equal to the thickness of the substrate 1.

[0053] When any hair inlet 2 in the substrate 1 is surrounded by four cobonded edges 3, in production, the four cobonded edges 3 can be set as two supporting cobonds 31 and two hair removal cobonds 32 with different thicknesses and staggered arrangement. In this way, the two opposing hair removal cobonds 32 form stepped structures 33 in the four directions of transverse and longitudinal directions. When the static blade slides along the skin in any of the four directions of transverse and longitudinal, the stepped structures 33 in the hair removal cobonds 32 can remove hair from the hair that is close to the skin, ensuring the hair inlet efficiency and trimming effect of the static blade.

[0054] Example 2

[0055] like Figures 4-6As shown in Figures 7-9, in the substrate 1, with the origin as the reference, several pores 2 are arranged alternately and staggered on the X and Y axes to form a trimming area for several pores 2. In the trimming area, except for the outermost pores 2, each pore 2 is surrounded by six cobonded edges 3. Among them, three staggered support cobonds 31 and scraping cobonds 32 are formed in the six cobonded edges 3. The thickness t1 of the support cobond is less than the thickness t2 of the scraping cobond, and the thickness t2 of the scraping cobond is less than or equal to the thickness of the substrate 1.

[0056] When any hair inlet 2 in the substrate 1 is surrounded by six cohesive edges 3, in production, the six cohesive edges 3 can be set as three supporting cohesive bonds 31 and three hair-shaving cohesive bonds 32 with different thicknesses and staggered arrangement. In this way, the two opposing hair-shaving cohesive bonds 32 form stepped structures 33 in multiple directions such as transverse, longitudinal and oblique. When the static blade slides along the skin in multiple directions such as transverse, longitudinal and oblique, the stepped structures 33 in the hair-shaving cohesive bonds 32 can all have a hair-shaving effect on the hair close to the skin, ensuring the hair inlet efficiency and trimming effect of the static blade.

[0057] Example 3

[0058] like Figures 10-12 As shown, in the substrate 1, with the origin as the reference, a number of pores 2 are arranged alternately and staggered on the X and Y axes to form a trimming area of ​​pores 2. In the trimming area, except for the outermost pores 2, each pore 2 is surrounded by twelve cobonded edges 3. Among them, six staggered support cobonds 31 and scraping cobonds 32 are formed in the twelve cobonded edges 3. The thickness t1 of the support cobond is less than the thickness t2 of the scraping cobond, and the thickness t2 of the scraping cobond is less than or equal to the thickness of the substrate 1.

[0059] When any hair inlet 2 in the substrate 1 is surrounded by twelve cohesive edges 3, in production, the twelve cohesive edges 3 can be set as six supporting cohesive bonds 31 and six hair-shaving cohesive bonds 32 with different thicknesses and staggered arrangement. In this way, the two opposing hair-shaving cohesive bonds 32 form stepped structures 33 in any direction. When the static blade slides along the skin in any direction, the stepped structures 33 in the six hair-shaving cohesive bonds 32 can all have a hair-shaving effect on the hair that is close to the skin, ensuring the hair inlet efficiency and trimming effect of the static blade.

[0060] In the technical solution with multiple shaving cobonds 32, the thickness t2 of the multiple shaving cobonds in the trimming area may be the same or different, preferably the thickness t2 of the multiple shaving cobonds is the same; however, if the thickness is relatively thick (e.g., greater than 0.5 mm), the multiple shaving cobonds 32 can also be set to different thicknesses. When the static blade slides on the skin surface, it can form multiple shaving actions on the skin surface, maximizing the lifting of hair close to the skin surface, improving the hair entry efficiency and hair trimming efficiency of the static blade. In the actual production process, it is only necessary to ensure that the thickness t2 of the shaving cobond is greater than the thickness t1 of the supporting cobond to form a stepped structure 33 to achieve the technical purpose of lifting hair close to the skin surface. Therefore, no further restrictions are made in this embodiment.

[0061] Existing shavers, hair removers, or lint removers mainly operate in either rotary or reciprocating modes. To broaden the applicability of the stationary blade, the base plate 1 is circular, and the trimming area composed of several hair inlets 2 covers the outer surface of the base plate 1. In this way, the stationary blade can be used in rotary shavers, hair removers, or lint removers.

[0062] Of course, the substrate 1 can also be set to a square shape, and the trimming area composed of several arrays of hair inlets 2 is square and smaller than the substrate 1, and is curved into a U shape with the X-axis as the center. In this case, the static blade can be applied to reciprocating shavers, hair removers or hair removal devices.

[0063] To ensure the efficiency of the static blade's hair entry, the hair entry hole 2 is one of the following shapes: round, triangular, square, rhomboid, hexagonal, or irregular. Hexagonal is preferred, but it can be determined according to user or market demand during specific production. This embodiment does not impose further restrictions.

[0064] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the specific implementation of the present invention. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
