Knife net structure of rotary shaver and machining method thereof

Abstract

The invention discloses a knife net structure of a rotary shaver. The knife net structure comprises a knife net body, a protruding annular shaving track is arranged on the knife net body, the shavingtrack comprises an outer ring side face, an inner ring side face and a track top face used for connecting the outer ring side face and the inner ring side face, outer hair inlet grooves and inner hairinlet grooves are formed in the shaving track, wherein the outer hair inlet grooves and inner hair inlet grooves are separated from one another, the outer hair inlet grooves extend to the middle of the shaving track from the outer ring side face, the inner hair inlet grooves extend to the middle of the shaving track from the inner ring side face, the multiple outer hair inlet grooves and the multiple inner hair inlet grooves are distributed in the circumferential direction, the outer hair inlet grooves and the inner hair inlet grooves are formed in a staggered mode, and outer horn hair guideopenings corresponding to the outer hair inlet grooves and used for guiding hair into the outer hair inlet grooves are formed in the turning joints between the outer ring side face and the track top face. The invention further discloses a machining method of the knife net structure of the rotary shaver. The machining method is simple in process, and the knife net structure is good in hair feedingeffect, capable of preventing hair leakage, high in shaving efficiency and capable of achieving the organic unification of high shaving safety and good shaving comfort.

Description

【Technical field】 [0001] The invention relates to a knife net structure of a rotary shaver, and also relates to a processing method of the knife net structure of a rotary shaver. 【Background technique】 [0002] At present, the cutter net of the existing rotary razor needs to feed the hair while moving, usually by setting a straight groove on the circular shaving track for the hair to enter, and combining with the moving knife rotating in the shaving track. cutting. Since the straight groove structure is easier for the skin to squeeze in, in order to ensure safety and not cut the skin, the width of the straight groove structure needs to be smaller. If the width of the straight groove is small, the hair inlet will be small and the hair will be difficult to feed. In order to ensure the effect of hair feeding, it is necessary to set as many straight grooves as possible. The usual structure is that the circumferential direction of the shaving track is regularly and evenly distri...

AI Technical Summary

Problems solved by technology

[0003] In the straight groove of the above-mentioned through groove structure, after the hair enters from a certain straight groove, one kind of situation is that before the hair runs out of the straight groove, the movable knife rotates to the position of the straight groove to cut off the incoming hair. The situation is that when the moving knife does not rotate to the position of the straight groove, the hair has already run out of the straight groove, resulting in hair loss and affecting the efficiency of shaving

Moreover, since the width of the cutting edge of the moving knife is usually smaller than the inner cavity of the shaving track, and there is a gap with the inner and outer side walls of the inner cavity, the hair enters from one end of the straight groove and is not cut by the driven knife, but from the other end. When running out, due to the sharp inner edge of the straight groove wall and the limited space, it will cause hair pulling and hair pulling, which will hurt the skin and affect the comfort of shaving

[0004] Of course, in order to solve the problem of hair leakage after the hair enters the straight groove and then runs out, some knife nets do not use a through groove structure. The cutting area of ​​the moving knife covers the cut-off part of the straight groove. When the hair enters the straight groove and moves to the end, if the moving knife has not rotated, it can stop at the cut-off position for a period of time and will not run out, which can be used for rapid rotation The moving knife comes to the back to cut, which improves the cutting efficiency to a certain extent, but it sacrifices the effect of feeding hair from the side of the inner ring

[0005] Although the rotary razor technology is quite mature after decades of development, the knife net of the rotary razor basically cannot get rid of the above-mentioned hair-feeding structure
