Description

Technical Field

[0001] The present application belongs to the field of hair clippers, and more specifically, to a movable blade structure for hair clippers. Background Art

[0002] In the hairdressing industry, hair clippers are undoubtedly an indispensable tool for every hairdresser. As one of the core structures of hair clippers, the design, material and performance of the moving blade directly affect the effect and efficiency of hair cutting. With the development of technology and consumers' pursuit of diversified hairstyles, the requirements for the moving blades of hair clippers are also increasing.

[0003] Traditional hair clipper moving blades are mostly made of stainless steel, which is popular for its high hardness and excellent wear resistance. However, with the advancement of technology, the application of new ceramic materials has brought more possibilities for moving blades. The new ceramic material not only retains the hardness and wear resistance of stainless steel, but also has significant improvements in corrosion resistance, toughness and lightweight, so that the moving blades can still remain sharp after long-term use and are not easily damaged. However, due to the design and structural limitations of traditional hair clipper moving blades, the use of ceramic materials to prepare moving blades has the disadvantage of high cost. At the same time, there is also the disadvantage of large deformation during sharpening, resulting in a low yield rate, which makes it impossible to be promoted and used on a larger scale. Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a movable blade structure for hair clippers to solve the technical problem in the prior art that the movable blades of hair clippers are made of ceramic materials with high cost.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is: to provide a movable blade structure for hair clippers, comprising:

[0006] A body, with a first step surface and a second step surface formed on the same side in parallel, wherein the first step surface is further away from the center of gravity of the body than the second step surface;

[0007] A cutting tooth connected to the first step surface and forming a cutting edge surface parallel to the first step surface at an end away from the first step surface;

[0008] A frustum is connected to the second step surface and is evenly arranged in multiple pieces along the extension direction of the second step surface. The end of the frustum away from the second step surface is flush with the cutting edge surface. The body, the blade teeth and the frustum are an integrated structure formed by static pressing and sintering of zirconia ceramic powder.

[0009] Optionally, the movable blade structure for hair clippers further comprises a rectangular boss connected to the second step surface, and one end of the rectangular boss away from the second step surface is flush with the cutting edge surface;

[0010] The end surface area of ​​the rectangular boss that is flush with the cutting edge surface is larger than the end surface area of ​​the truncated cone that is flush with the cutting edge surface.

[0011] Optionally, the rectangular boss is located on an edge of a side of the second step surface away from the first step surface.

[0012] Optionally, the rectangular boss is provided with an inwardly recessed groove on the end surface that is flush with the cutting edge surface.

[0013] Optionally, a through hole penetrating the body is provided on the second step surface.

[0014] Optionally, a cavity recessed inwardly from the second step surface is provided on the main body.

[0015] Optionally, a fork for connecting an external driving device is provided on the main body, and the frustum is symmetrically arranged on both sides of the fork along the depth direction of the fork.

[0016] Optionally, a trapezoidal boss with a small end away from the body is integrally formed on a side of the body away from the second step surface;

[0017] The side wall of the trapezoidal boss is connected to the main body to form the side wall of the fork.

[0018] Optionally, the trapezoidal bosses are symmetrically arranged on both sides of the fork along the depth direction of the fork.

[0019] Optionally, a long groove extending in a direction parallel to the arrangement direction of the blade teeth is provided on a side of the main body away from the second step surface.

[0020] The beneficial effect of the movable blade structure for hair clippers provided by the present application is that: compared with the prior art, in the movable blade structure for hair clippers provided by the present application, the structure of the body, the blade teeth and the truncated cone are an integrally formed structure formed by static pressing and sintering of zirconium oxide ceramic powder. Since the body forms a parallel first step surface and a second step surface, the blade teeth connected to the first step surface form a cutting edge surface at the end away from the first step surface, and the truncated cone connected to the second step surface is flush with the cutting edge surface at the end away from the second step surface, so the truncated cone provided on the body can be used to stably support the body so that the blade teeth can always closely match the static blade and maintain good relative movement smoothness during the movement process, and the body with a step structure design can significantly reduce the amount of ceramic powder used in the movable blade structure for hair clippers in the present application, thereby significantly reducing the production cost of the movable blade, and at the same time, through the auxiliary support of the truncated cone, the deformation of the body is effectively avoided when sharpening the blade teeth, and the yield rate of the movable blade is significantly improved, which is far superior to the prior art.

[0031] Please also read Figures 1 to 4 Now, a movable blade structure for hair clippers provided in an embodiment of the present application is described. The movable blade structure for hair clippers includes a body 101, blade teeth 104 and a round table 106. Among them:

[0032] The first step surface 102 and the second step surface 103 are formed parallel to each other on the same side of the body 101. The first step surface 102 is farther away from the center of gravity of the body 101 than the second step surface 103. The blade teeth 104 are connected to the first step surface 102 and form a cutting edge surface 105 parallel to the first step surface 102 at the end away from the first step surface 102. The frustum 106 is connected to the second step surface 103 and is evenly arranged in a plurality along the extension direction of the second step surface 103. The end of the frustum 106 away from the second step surface 103 is flush with the cutting edge surface 105. The body 101, the blade teeth 104 and the frustum 106 are an integrally formed structure formed by static pressing and sintering of zirconia ceramic powder. It can be understood that in this embodiment, the frustum 106 is used to abut against the stationary blade opposite to the moving blade after the moving blade is installed on the driving structure, so as to maintain the structural stability of the moving blade on the one hand, so that it will not be bent and deformed during the installation on the driving structure, and on the other hand, it can improve the relative movement stability of the moving blade and the stationary blade.

Therefore, the frustum 106 arranged on the main body 101 can be used to stably support the main body 101 and enable the blade tooth 104 to always closely fit the static blade and maintain good relative movement smoothness during the movement. At the same time, through the auxiliary support of the frustum 106, the deformation of the main body is effectively avoided when sharpening the blade tooth 104, and the yield rate of the moving blade is significantly improved. In addition, the main body 101 with a step structure design can significantly reduce the amount of ceramic powder used in the moving blade structure of the hair clippers in this embodiment, thereby significantly reducing the production cost of the moving blade, which is far superior to the prior art.
