Continuous four-blade seamless rotary type shaver head system with large-circle arc

Abstract

The invention discloses a continuous four-blade seamless rotary type shaver head system with a large-circle arc, which comprises a blade mesh, a first movable razor, a second movable razor, a balance fixing plate and a plastic connecting piece, wherein the first and the second movable razors are welded and fixed through laser; and the balance fixing plate and the plastic connecting piece are integrally formed through an injection moulding technology, and are fixed and connected with the four layers of razor blades of the first and the second razors through laser welding into a seamless four-blade shaver head system. By the shaver head system, the beard clamping, pulling and drawing defects of a traditional shaver can be effectively overcome, and the shaver head system has high beard capture efficiency and a good face attachment effect, so better shaving acoustic quality and shaving skin-touch can be obtained.

Description

technical field [0001] The present invention relates to a rotary shaver head system. Background technique [0002] In the existing rotary razor heads on the market, the outer surface of the knife net is generally at a right angle or a small arc R, which has a poor veneer effect and is not conducive to the entry of long beards, resulting in incomplete shaving and poor shaving efficiency. Low, and easy to produce the defects of pinching and pulling beards; and the top surface of the knife net generally has 2 to 3 or more spacer strips, which reduce the limited use area of ​​the knife net (30% left and right), which directly reduces the shaving area and shaving efficiency; at the same time, the positioning column of the knife net is generally a traditional blind hole, which makes the hardware mold very complicated. The traditional blind hole stretches 7 to 8 times or more. This increases the manufacturing cost, and it is difficult to guarantee the accuracy of the outer circle ...

Problems solved by technology

[0002] In the existing rotary razor heads on the market, the outer surface of the knife net is generally at a right angle or a small arc R, which has a poor veneer effect and is not conducive to the entry of long beards, resulting in incomplete shaving and poor shaving efficiency. Low, and easy to produce the defects of pinching and pulling beards; and the top surface of the knife net generally has 2 to 3 or more spacer strips, which reduce the limited use area of ​​the knife net (30% left and right), which directly reduces the shaving area and shaving efficiency; at the same time, the positioning column of the knife net is generally a traditional blind hole, which makes the hardware mold very complicated. The traditional blind hole stretches 7 to 8 times or more. This increases the manufacturing cost, and it is difficult to guarantee the accuracy of the outer circle of the column; the traditional knife nets on the market are not evenly arranged, and the beard holes are either concentrated in the innermost circle or partially concentrated in the outermost circle. Two or three circles, which is not conducive to the comprehensive capture of short beards; the top surface (beard entry surface) of traditional knife nets on the market is either flat or partially arched, the veneer effect is not good, and it is not conducive to the entry of long beards

[0003] In the existing rotary razor heads on the market, the moving knife is generally separated by a spacer to form a separate, intermittent shaving system, and there is generally about 0.2-0.4 between the blade and the knife net into the shaving groove. Gaps and crevices, long beards have the opportunity to enter these crevices during shaving, causing defects of beard pinching, beard pulling and plucking.
