Shaver external cutter net structure

Abstract

The invention discloses a shaver external cutter net structure. The structure comprises a metal surface body making contact with the skin and beard and a barrel used for assembly. The metal surface body and the barrel are independent from each other. An external ring cutting groove is formed in the metal surface body. Bar-shaped hair inlet holes are formed in the external ring cutting groove. Hairguide teeth protruding outwards are formed in the outer circumferential surface of the upper end of the barrel and form a comb-shaped structure. The outer side wall of the external ring cutting groove is fixed to the roots of the hair guide teeth, and accordingly, the metal surface body and the barrel are assembled and fixed. A hair guide groove communicating with the corresponding hair inlet hole is formed in every two adjacent hair guide teeth. The hair guide teeth are used for making contact with the skin and beard, and the hair can be combed, so that the hair better enters the external ring cutting groove through the hair guide grooves and the hair inlet holes. According to the shaver external cutter net structure, the outer side wall of the external ring cutting groove and the barrelare connected and fixed, the metal surface body is simple in connecting structure, the external ring cutting groove and relevant grooves and holes of the metal surface body can be prevented from being blocked, the hardware forming technology is simple, and production and manufacturing are easy.

Description

【Technical field】 [0001] The invention relates to a shaver outer cutter net structure. 【Background technique】 [0002] Rotary electric shavers are commonly used. The cutter assembly is the heart of a rotary electric shaver. The cutter assembly mainly includes a rotating cutter and a cutter net covering the cutter inside. The knife net in the prior art is a cylinder with a bottom at one end and an open end at the other end. The bottom of the cylinder faces upwards, and the beards that are regularly arranged on the bottom surface allow the beards to enter the knife net so that the beards cut off by the cutter enter the mouth and enter. The mouth is in the shape of a strip, or the entrance is a combination of a strip and a round hole, and the bottom surface of the cylinder and the wall of the cylinder are integrated. The structure of the bottom surface of the knife net and the cylinder wall as one body has at least the following disadvantages: the part of the knife net in co...

AI Technical Summary

Problems solved by technology

The structure of the bottom surface of the knife net and the cylinder wall as one body has at least the following disadvantages: the part of the knife net in contact with the face needs to be very thin to ensure the shaving effect, and the cylinder wall used as support and installation needs to have certain mechanical strength. Strength generally needs to reach a certain thickness, and the processing generally requires multiple stretching processes, the manufacturing process is complicated, the processing is difficult, the production efficiency is low, the manufacturing cost is high, and it is prone to cracks and other defects.

[0004] 1. The fixing of the surface body and the cylinder adopts the method of setting the steps of the assembly interface to match the inner diameter of the cylinder. The stretching and forming process of the step structure of the interface is also added, and the structure makes the interface step from the outer wall of the outer ring slit If the interface step is blocked under the outer ring sipes, it will increase the difficulty of forming the outer ring sipes or interface steps, and the manufacturing process of the surface body is complicated; moreover, when the injection molding process is used, the shrinking interface steps lead to surface body The positioning in the injection mold is complicated, and the structure of the resist to prevent the plastic solution from entering the surface body is complicated. Therefore, the injection molding process is complicated and the manufacturing cost is high.

[0005] 2. The outer wall of the outer ring sipe is located above the cylinder. Due to the thinner surface material and low strength, it is easy to cause the top surface of the surface body and the outer wall of the outer ring sipe to collapse when the external force collides, resulting in the destruction of the entire knife net. destroy

[0006] 3. This structure does not improve the guide and feed structure of the existing outer knife net
