Description

[Technical Field]

[0001] This utility model relates to a blade mesh assembly, and also to a razor blade assembly. [Background Technology]

[0002] Existing dry shavers have several sets of elongated blades on their shaver heads, as disclosed in patent publication CN100579735C, entitled "Dry Shaver." The blade set includes an elongated foil and inner blades. The foil is mounted on a mounting frame, typically a plastic frame. The foil is bent along the outer side of the plastic frame and wrapped around it, forming a semi-cylindrical structure. Positioning posts are formed on the sidewalls of the plastic frame along its length, and positioning holes are made on the sidewalls of the foil. The positioning posts are inserted into these holes, and then the positioning posts are heat-pressed to fix the left and right sidewalls of the foil to the left and right sidewalls of the plastic frame. However, this design has the following drawbacks:

[0003] 1. Because the mounting bracket has a certain length and needs to leave an inner cavity for the inner blade to move inside, the side wall of the mounting bracket in the length direction is often relatively weak. The long blade net is easily twisted when installed on the mounting bracket, which leads to poor fit between the inner blade and the blade net in some positions, resulting in a dull cutting edge.

[0004] 2. Another mounting bracket needs to have a certain material thickness on the side wall along the length direction to ensure its strength, which relatively reduces the width of the inner cavity, making the width of the inner blade smaller. The width of the inner blade is smaller, and the width of the effective cutting area is also smaller, reducing the cutting efficiency.

[0005] 3. The blade mesh is made of thin sheet material and is elastic. It is fixed to the side wall of the mounting bracket via the left and right side walls. Its curved top is not fixed. After the blade mesh is bent and fixed to the mounting bracket, the curve of its top is often not a round arc and the shape is unstable. The inner blade, on the other hand, is made of a thicker metal material and is formed by stamping. Its top surface can form a stable round arc shape. Although the inner blade is pressed upward from the bottom of the blade mesh by a spring, which can force the blade mesh to deform to a certain extent and make the inner blade fit better with the blade mesh, it is also easy for the blade mesh and the inner blade to not fit well, resulting in poor cutting sharpness.

[0006] This utility model was made based on this situation. [Utility Model Content]

[0007] The technical problem to be solved by this utility model is to provide a structurally stable blade mesh assembly.

[0008] To solve the above-mentioned technical problems, this utility model provides a blade mesh assembly for a shaver, including a blade mesh and a rigid blade mesh support. The blade mesh support is integrally formed from metal and includes front and rear side walls, as well as arc-shaped portions connecting the front and rear side walls from the top at the left and right ends respectively. The arc-shaped portion at each end forms an inverted "U" shape with the front and rear side walls. The blade mesh support has an inner blade movement opening between the left and right arc-shaped portions. The blade mesh is fixed on the outer side of the blade mesh support. The blade mesh passes from the front side wall, through the arc-shaped portions, and then around to the rear side wall, covering the inner blade movement opening. The inner sides of the blade mesh and the blade mesh support form an inner cavity for the inner blade assembly to move within.

[0009] As described above, in a blade mesh assembly, the left and right ends of the blade mesh support are provided with end caps, the end caps are located outside the arc-shaped portion and the outer surface of the end caps is located outside the blade mesh.

[0010] As described above, in a blade mesh assembly, the blade mesh bracket is stamped from sheet metal, and its left and right ends are respectively provided with lateral bending portions that bend inward from the two side walls. The lateral bending portions are provided with fixing holes. The end cap is made of plastic and is provided with fixing posts inserted into the fixing holes. The fixing posts fix the lateral bending portions to the end cap.

[0011] As described above, in a blade mesh assembly, the arc-shaped portion has a downwardly bent portion, the downwardly bent portion has a fixing hole, and the end cap has a fixing post inserted into the fixing hole, the fixing post fixing the downwardly bent portion to the end cap.

[0012] As described above, in a blade mesh assembly, the end cap is provided with a recessed positioning groove that mates with the lateral bending portion and the downward bending portion.

[0013] As described above, in a blade mesh assembly, the left and right ends of the blade mesh bracket form ports above the lateral bending portions, and the end cap is provided with a reinforcing portion inserted into the port, the side of the reinforcing portion being close to or attached to the inner surface of the port.

[0014] As described above, in a blade mesh assembly, the blade mesh is fixed to the outside of a blade mesh bracket along the inverted "U"-shaped outer contour formed by the arc-shaped part and the front and rear side walls. The arc-shaped part is a circular arc structure connecting the front and rear side walls. The inner side of the blade mesh is attached to the arc-shaped part, forming a corresponding circular arc structure in the upper middle part of the blade mesh.

[0015] As described above, in the left-right direction, the end cap is provided with a buckle and a guide post facing outwards.

[0016] As described above, in a blade mesh assembly, the front and rear side walls of the blade mesh bracket are provided with a plurality of assembly positioning holes A, and the blade mesh is provided with assembly positioning holes B corresponding to the assembly positioning holes A. The blade mesh is welded and fixed to the front and rear side walls of the blade mesh bracket.

[0017] As described above, a blade mesh assembly has mesh holes for cutting, a blade mesh hole strip below the mesh holes, and a plurality of rows of blade mesh through holes arranged from left to right from top to bottom on the blade mesh. A welding part is provided below the blade mesh through holes.

[0018] As described above, in one type of blade mesh assembly, the top of the blade mesh has an upwardly convex arc-shaped structure in the length direction.

[0019] As described above, in the left-right direction, the lower end of the end cap is provided with a spring support arm extending inward, and the spring support arm is provided with an upward-facing spring positioning post.

[0020] Another technical problem to be solved by this utility model is to provide a blade assembly for a razor that has a stable structure and good cutting performance.

[0021] To solve the above-mentioned technical problems, this utility model provides a razor blade assembly with the aforementioned foil assembly, further comprising an inner blade assembly. The foil is fixed to the outer side of a foil support along an inverted "U"-shaped outer contour formed by an arcuate portion and two front and rear sidewalls. The arcuate portion is a circular arc structure connecting the front and rear sidewalls. The inner side of the foil adheres to the arcuate portion, forming a corresponding circular arc structure in the upper middle part of the foil. The inner blade assembly includes an inner blade support and an inverted "U"-shaped inner blade mounted on the inner blade support. The inner blade has circular arc-shaped cutting teeth corresponding to the inner side of the foil, and these cutting teeth are tightly attached to the inner side of the foil.

[0022] Another technical problem to be solved by this utility model is to provide a blade assembly for a razor that has a stable structure and good cutting performance.

[0023] To solve the above-mentioned technical problems, this utility model provides a razor blade assembly with the aforementioned foil assembly, further comprising an inner blade assembly. The inner blade assembly includes an inner blade support and an inverted "U"-shaped inner blade mounted on the inner blade support. The inner blade includes front and rear mounting portions and cutting teeth located at the upper part. An inner blade hole band is provided between the cutting teeth and the mounting portions. The inner blade hole band has several rows of inner blade through holes arranged from left to right from top to bottom. The top of the foil is an upwardly convex arc-shaped structure in the length direction, and the top of the inner blade is an upwardly convex arc-shaped structure that cooperates with the foil in the length direction.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. The blade holder of this utility model includes front and rear side walls, and arc-shaped portions connecting the front and rear side walls from the top at both ends. The arc-shaped portion at each end forms an inverted "U" shape with the front and rear side walls. The blade holder passes from the front side wall through the arc-shaped portion and then wraps around to the rear side wall to be fixed to the outer side of the blade holder. The blade holder is integrally formed of metal, possessing rigidity, good structural strength, and structural stability, which helps to prevent the blade holder installed on it from twisting and deforming. Furthermore, because the rigid metal ensures structural strength, it allows the front and rear side walls of the blade holder to be made thinner, thereby increasing the width of the inner cavity in the front-rear direction, which in turn increases the width of the inner blade and increases the cutting area.

[0026] 2. The blade mesh is fixed to the outside of the blade mesh bracket along the inverted "U" shaped outer contour formed by the curved section and the front and rear side walls. This design facilitates a stable structure during manufacturing, and the blade mesh's fixation against the bracket's outer contour helps achieve a stable shape, reducing cutting defects caused by variations in the blade mesh's shape. The curved section is a circular arc structure connecting the front and rear side walls. The inner side of the blade mesh adheres to the curved section, forming a corresponding circular arc structure in the upper middle part of the blade mesh. The circular arc shape of both the curved section and the upper middle part of the blade mesh facilitates manufacturing and allows the inner blade to be made into a circular arc shape to match the blade mesh.

[0027] 3. The blade mesh bracket is made of sheet metal and the end cap is made of plastic. The blade mesh bracket forms a fixed connection structure with two lateral bends and one downward bend, corresponding to the three fixing posts on the end cap, in a triangular distribution, which ensures a stable connection.

[0028] 4. The blade assembly of this utility model includes a blade mesh assembly and an inner blade assembly. The inner side of the blade mesh is attached to the arc-shaped part, and the upper middle part of the blade mesh forms a corresponding arc structure. The inner blade assembly includes an inner blade support and an inverted "U"-shaped inner blade mounted on the inner blade support. The inner blade is provided with arc-shaped cutting teeth corresponding to the inner side of the blade mesh. The cutting teeth are tightly attached to the inner side of the blade mesh. The arc-shaped part, the upper middle part of the blade mesh, and the cutting teeth are arc-shaped, which is conducive to processing and manufacturing, and facilitates better fitting of the cutting teeth to the blade mesh to improve the sharpness of cutting.

[0029] 5. The blade assembly of this utility model has an upwardly convex arc-shaped structure at the top of the blade net in the length direction, and an upwardly convex arc-shaped structure at the top of the inner blade that cooperates with the blade net in the length direction. This facilitates shaving the concave areas of the body. The inner blade has an inner blade hole band between the mounting part and the cutting teeth. When the top of the inner blade is stamped into an arc-shaped structure in the longitudinal direction, the area where the inner blade hole band is located is conducive to deformation, which is conducive to forming a stable cutting tooth structure. At the same time, it can also prevent the deformation from spreading to other structures of the inner blade mounting part. [Attached Image Description]

Detailed Implementation Methods

[0039] The present invention will be further described below with reference to the accompanying drawings:

[0040] like Figures 1 to 7 The diagram shows a razor foil assembly for a razor, comprising a razor foil 1 and a rigid razor foil support 2. The razor foil support 2 is integrally formed from metal and includes front and rear side walls 21, and arcuate portions 22 connecting the front and rear side walls 21 from the top at the left and right ends respectively. The arcuate portion 22 at each end forms an inverted "U" shape with the front and rear side walls 21. The razor foil support 2 has an inner blade movement opening 23 between the left and right arcuate portions 22. The razor foil 1 is fixed to the outer side of the razor foil support 2. The razor foil 1 passes from the front side wall 21, through the arcuate portion 22, and then around to the rear side wall 21, covering the inner blade movement opening 23. The inner sides of the razor foil 1 and the razor foil support 2 form an inner cavity 3 for the inner blade assembly to move within.

[0041] The blade holder 2 is integrally formed from metal, possessing rigidity, high structural strength, and structural stability, which helps prevent the blade installed on it from twisting and deforming. Furthermore, the rigidity of the metal ensures structural strength while allowing for thinner front and rear side walls 21 of the blade holder 2, thereby increasing the width of the inner cavity 3 in the front-rear direction, thus increasing the width of the inner blade and expanding the cutting area.

[0042] Preferably, the blade mesh 1 is fixed to the outside of the blade mesh bracket 2 along the inverted "U" shaped outer contour formed by the arc-shaped part 22 and the front and rear side walls 21. Since the blade mesh bracket 2 is conducive to forming a stable structure during the manufacturing process, the blade mesh 1 is fixed along the outer contour of the blade mesh bracket 2, which helps to form a stable shape and reduces the cutting defects caused by the shape difference of the blade mesh 1 contour.

[0043] Preferably, such as Figure 4 As shown, the arc-shaped part 22 is an arc structure connecting the front and rear side walls 21. The inner side of the blade net 1 is attached to the arc-shaped part 22 and the upper middle part of the blade net 1 forms a corresponding arc structure. The arc-shaped part 22 and the upper middle part of the blade net 1 are arc-shaped, which is conducive to processing and manufacturing, and also facilitates the inner blade to be made into an arc shape to cooperate with the blade net 1.

[0044] Preferably, the left and right ends of the blade mesh support 2 are provided with end caps 4. The end caps 4 are located outside the arc-shaped portion 22, and their outer surface is located outside the blade mesh 1 so as to block the end of the blade mesh 1 and prevent the end of the blade mesh 1 from being exposed and in contact with the skin.

[0045] Preferably, the blade holder 2 is stamped from sheet metal, and its left and right ends are respectively provided with lateral bending portions 24 that bend inward from the two side walls 21. The lateral bending portions 24 are provided with fixing holes 25, and the end cap 4 is provided with fixing posts 41 that are inserted into the fixing holes 25. The fixing posts 41 fix the lateral bending portions 24 to the end cap 4. Preferably, the end cap 4 is made of plastic. During installation, after the fixing posts 41 are inserted into the fixing holes 25, the fixing posts 41 are heat-deformed to press them onto the lateral bending portions 24, thereby fixing the end cap 4 and the blade holder 2 together.

[0046] Furthermore, the arc-shaped portion 22 is provided with a downwardly bent portion 26, and the downwardly bent portion 26 is also provided with a fixing hole 25. The end cap 4 is provided with a fixing post 41 inserted into the fixing hole 25, and the fixing post 41 fixes the downwardly bent portion 26 to the end cap 4. The two lateral bends 24 cooperate with one downwardly bent portion 26, and the end cap 4 is fixed to the blade holder 2 by three fixing posts 41 distributed in a triangle, so that the connection is stable.

[0047] Preferably, the end cap 4 is provided with a recessed positioning groove 42 that cooperates with the lateral bending portion 24 and the lower bending portion 26, which facilitates positioning and installation.

[0048] Preferably, the left and right ends of the blade holder 2 form ports 27 above the lateral bending portion 24, and the end cap 4 is provided with a reinforcing portion 43 inserted into the port 27. The side of the reinforcing portion 43 is close to or attached to the inner surface of the port 27 so as to prevent the blade holder 2 from deforming during the production and assembly process.

[0049] Of course, the blade holder 2 and the end cap 4 can also be integrally formed by powder metallurgy.

[0050] Preferably, the front and rear side walls 21 of the blade holder 2 are provided with a plurality of assembly positioning holes A28, and the blade 1 is provided with assembly positioning holes B11 corresponding to the assembly positioning holes A28. During assembly production, the blade is bent along the outer contour of the blade holder 2, and the assembly positioning holes A28 and B11 are aligned. Then, external positioning pins are inserted to fix the blade 1 and the blade holder 2. The blade 1 is then welded to the front and rear side walls 21 of the blade holder 2, and the external positioning pins are then removed.

[0051] Preferably, the blade mesh 1 is provided with mesh holes 12 for cutting, and a blade mesh hole strip 13 is provided below the mesh holes 12. The blade mesh hole strip 13 has several rows of blade mesh through holes 14 arranged from left to right from top to bottom. The blade mesh 1 is provided with a welding part 15 below the blade mesh through holes 14. The blade mesh hole strip 13 is provided between the welding part 15 and the mesh holes 12, which helps to reduce the influence of the deformation generated by welding of the welding part 15 on the part of the blade mesh with mesh holes 12, and avoids the twisting deformation of the part of the blade mesh with mesh holes 12 from affecting the cooperation with the inner blade.

[0052] Preferably, such as Figure 7 As shown, the top of the blade mesh 1 has an upwardly convex arc shape along its length to facilitate shaving the concave areas of the body. During stamping, the area corresponding to the blade mesh holes 13 is conducive to deformation, thereby facilitating the stamping of the top of the blade mesh 1 into an upwardly convex arc shape and preventing deformation of the mesh holes 12 from affecting cutting performance. Of course, as... Figure 3 and Figure 6 As shown, the top of the blade mesh 1 can also be a straight or nearly straight structure in the length direction.

[0053] Preferably, in the left-right direction, the end cap 4 is provided with a buckle 44 and a guide post 45 facing outward. After the blade mesh assembly is installed on the blade head housing, the guide post is used to guide the blade head housing to move up and down, and the buckle 44 is used to prevent the blade mesh assembly from coming off the blade head housing upward.

[0054] exist Figure 5-6In the illustrated embodiment, in the left-right direction, the lower end of the end cap 4 is provided with an inwardly extending spring support arm 46, and the spring support arm 46 is provided with an upwardly facing spring positioning post 47. After the inner blade assembly is installed in the inner cavity 3 of the blade mesh assembly, a spring can be installed between the spring support arm 46 and the inner blade assembly to elastically press the inner blade assembly upward onto the blade mesh. Of course, it can also be as follows: Figure 1-4 In the embodiment shown, the end cap 4 does not have a spring support arm 46 to install a spring to press the inner blade assembly. The inner blade assembly can be elastically pressed against the blade mesh by an external elastic device.

[0055] like Figure 1-4 The blade assembly of a razor shown includes the aforementioned foil assembly and an inner blade assembly. The inner blade assembly includes an inner blade support 5 and an inverted "U"-shaped inner blade 6 mounted on the inner blade support 5. The foil 1 is fixed to the outer side of the foil support 2 along the inverted "U"-shaped outer contour formed by the arcuate portion 22 and the front and rear side walls 21. The arcuate portion 22 is an arcuate structure connecting the front and rear side walls 21. The inner side of the foil 1 is attached to the arcuate portion 22, forming a corresponding arcuate structure in the upper middle part of the foil 1. The inner blade 6 is provided with arc-shaped cutting teeth 61 corresponding to the inner side of the blade mesh 1. The cutting teeth 61 are closely attached to the inner side of the blade mesh 1. During operation, the inner blade 6 reciprocates in the left-right direction on the inner side of the blade mesh 1 to cut off the hair that enters through the mesh. With the direction of movement of the inner blade as the longitudinal direction, the arc-shaped part 22, the upper middle part of the blade mesh 1 and the cutting teeth 61 adopt an arc-shaped structure in the direction perpendicular to the longitudinal direction, which is conducive to processing and manufacturing, and allows the cutting teeth 61 to better fit the blade mesh 1 to improve the sharpness of the cut.

[0056] like Figure 7 and Figure 8 The blade assembly of a shaver shown includes the aforementioned foil assembly and an inner blade assembly. The inner blade assembly includes an inner blade support 5 and an inverted "U"-shaped inner blade 6 mounted on the inner blade support 5. The inner blade 6 includes front and rear mounting portions 62 and cutting teeth 61 located at the upper part. An inner blade hole band 63 is provided between the cutting teeth 61 and the mounting portions 62. The inner blade hole band 63 has several rows of inner blade through holes 64 arranged from left to right from top to bottom. The top of the foil is an upwardly convex arc-shaped structure in the longitudinal direction, and the top of the inner blade 6 is an upwardly convex arc-shaped structure that cooperates with the foil 1, which is beneficial for shaving the concave areas of the body. The inner blade hole band 63 is provided between the mounting portion 62 and the cutting teeth 61. When the top of the inner blade 6 is stamped into an arc-shaped structure in the longitudinal direction, the area where the inner blade hole band 63 is located is conducive to deformation, which is conducive to forming a structurally stable cutting tooth 61, and at the same time, it can also prevent the deformation from spreading to other structures of the inner blade mounting portion 22.
