Description

Technical Field

[0001] This utility model relates to the field of plush trimming technology, and in particular to a blade head with 12 blades. Background Technology

[0002] A plush trimmer consists of a blade head and a mesh. The blade head typically has multiple fixed cutting blades. The rotation of the blade head causes the blades to rotate synchronously. Hair passes through the mesh of the mesh and is cut by the blades on the blade head behind the mesh, thus completing the trimming operation. To ensure a good trimming effect, the blades on the blade head are usually kept in close contact with the back wall of the mesh. However, after prolonged use, the blades will wear down and no longer maintain close contact with the mesh, resulting in a poorer trimming effect. Furthermore, errors during the installation of the plush trimmer can also cause the blades and mesh to not be in contact, affecting the trimming effect.

[0003] Therefore, how to keep the blade and the foil in close contact for a long time to ensure the hair-cutting effect has become a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a blade head with 12 blades to solve the problem that the shearing effect of existing blade heads deteriorates after long-term operation.

[0005] A blade head with 12 blades includes a blade holder body, which is disc-shaped. Multiple blade mounting portions are provided on one side of the blade holder body. The multiple blade mounting portions are evenly distributed around the circumference of the blade holder body. Blade guide grooves are provided on the blade mounting portions. A spring is fixed on the other side of the blade holder. The back of the blade is connected to the spring after passing through the blade guide groove. The cutting edge of the blade is attached to the inner wall of the blade net under the support of the spring.

[0006] Furthermore, the blade mounting section includes long blade mounting sections and short blade mounting sections, with six long blade mounting sections and six short blade mounting sections provided. The long blade mounting sections and the short blade mounting sections are distributed on the blade holder body at intervals. The interval angle between two adjacent long blade mounting sections is 60°, the interval angle between two adjacent short blade mounting sections is 60°, and the interval angle between any long blade mounting section and the adjacent short blade mounting section is 30°.

[0007] Furthermore, the blade mounting portion is provided with a limiting block for extending the depth of the blade guide groove.

[0008] Furthermore, the spring is disc-shaped and has multiple independent spring arms, the positions of which correspond to the positions of the blade mounting parts.

[0009] Furthermore, the spring sheet has multiple fixing holes for fixing the spring arm, and the multiple fixing holes are evenly distributed around the circumference of the spring sheet.

[0010] Furthermore, the blade includes a long blade and a short blade, the long blade being inserted into a blade guide groove on the long blade mounting part, and the short blade being inserted into a blade guide groove on the short blade mounting part; Both the long and short blades have mounting holes and back shoulders on their backs for connection with the spring arm latch.

[0011] Furthermore, at least three long blades and at least three short blades are provided, with the long blades and short blades evenly distributed around the circumference of the blade holder body.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows: With the combined action of the spring clip and the blade guide groove, the blade can be floatingly mounted on the blade holder without detaching from it. This floating mounting method allows the blade edge to remain in contact with the inner wall of the blade holder for extended periods, ensuring the trimming effect of the lint trimmer.

[0013] The long and short blades in this application are spaced apart, improving the uniformity of blade distribution between the center and periphery of the blade mesh, effectively solving the problem of uneven wear caused by too many blades densely distributed in a small area. The long blades remove hair from the central area of ​​the blade mesh, while the short blades work in conjunction with the long blades to shave hair from the periphery, ensuring the hair-cutting efficiency of the lint trimmer.
