Hair shaving knife head

Abstract

The invention relates to a hair shaving knife head. The hair shaving knife head is characterized in that a first guide rail, a second guide rail and a fixed guide rail are arranged at the bottom of anouter knife net, so that a first knife groove, a second knife groove, a third knife groove and a fourth knife groove are formed in the bottom of the outer knife net, one end of a hair inlet groove ineach of the first knife groove and the fourth knife groove is open and communicates with the outside, inner knife heads are correspondingly placed in the first knife groove, the second knife groove,the third knife groove and the fourth knife groove and are correspondingly attached to the bottom end faces of the first knife groove, the second knife groove, the third knife groove and the fourth knife groove. The hair shaving knife head has the beneficial effects that the first guide rail, the second guide rail and the fixed guide rail are arranged at the bottom of the outer knife net, so thatthe four independent knife grooves are formed in the bottom of the outer knife net, by adopting the structure of the four knife grooves, the length of the knife head in each knife groove can be shortened, the flatness forming requirement of the single knife head is correspondingly lowered, the machining difficulty of the knife head is reduced, the production benefit of the knife head is improved,and the production cost of the knife head is reduced.

Description

technical field [0001] The present invention relates to a cutter head assembly, more specifically to a razor head, which is mainly used in the field of razors. Background technique [0002] A patent assigned by the applicant: reciprocating razor middle knife, announcement number: CN100575008C, announcement date: 2009-12-30, which specifically discloses M-type fixed knife and M-like moving knife , and a spring is provided on the moving knife seat to ensure that the end faces of the moving knife and the fixed knife fit together. Although this type of structure can achieve hair shaving, it also has obvious defects during production and use. For example, the outer The cutting horizontal groove of the knife net (that is, the fixed knife) is semi-closed, and long hair or curly hair cannot enter the cutting horizontal groove, which affects the hair shaving efficiency; secondly, the moving knife head is only fixed in the base by a spring , when the driving mechanism drives the mova...

[0002] A patent assigned by the applicant: reciprocating razor middle knife, announcement number: CN100575008C, announcement date: 2009-12-30, which specifically discloses M-type fixed knife and M-like moving knife , and a spring is provided on the moving knife seat to ensure that the end faces of the moving knife and the fixed knife fit together. Although this type of structure can achieve hair shaving, it also has obvious defects during production and use. For example, the outer The cutting horizontal groove of the knife net (that is, the fixed knife) is semi-closed, and long hair or curly hair cannot enter the cutting horizontal groove, which affects the hair shaving efficiency; secondly, the moving knife head is only fixed in the base by a spring , when the driving mechanism drives the moving head to swing back and forth, it is prone to offset or misalignment, which will affect the fit between the end face of the moving head and the fixed knife, and affect the shaving effect
