Inner blade of electric shaver, and electric shaver having inner blade

Abstract

The invention discloses an inner blade of an electric shaver which is provided with a concave groove structure on a cutting blade. The inner blade of the electric shaver consists of pectinate blades and an inner connecting piece. The inner connecting piece is provided with an installation part, the pectinate blades and the installation part of the inner connecting piece are connected in the hot-pressing or imbedding mode, and the cutting blades of the pectinate blades are all provided with concave grooves. The inner blade of the electric shaver greatly enhances the processing efficiency of the blades because the grinding of the blades is reduced compared with that of the traditional process. In addition, the cutting blades with the concave groove structure effectively enhances the sharpness of the blades and the voice quality of the shaving, and have significantly effects on the reduction of the shaving load, the reduction of power consumption and the prolonging of the service life of the blade. The invention also discloses the electric shaver with the inner blade.

Description

technical field [0001] The invention relates to an electric shaver, in particular to an inner cutter head of the electric shaver. Background technique [0002] Such as figure 1 As shown, in the existing reciprocating shaving system, whether the inner cutter head of the electric shaver adopts the plastic insert molding method, or uses a comb-shaped metal sheet to bend the arched cutter head, the power of the electric shaver The source 10 is conducted by the motor to the middle part of the inner cutter head through the conduction mechanism. The inner cutter head 6 is in close contact with the outer cutter net 7, and cuts off the beard introduced from the outer cutter net by reciprocating motion. [0003] Since the motor speed of the shaver reaches more than 6000RPM during shaving, the power source is transmitted from the motor to the inner cutter head 6 through the transmission mechanism, so that the inner cutter head 6 performs reciprocating cutting motion at a high speed of...

AI Technical Summary

Problems solved by technology

[0003] Since the motor speed of the shaver reaches more than 6000RPM during shaving, the power source is transmitted from the motor to the inner cutter head 6 through the transmission mechanism, so that the inner cutter head 6 performs reciprocating cutting motion at a high speed of 0.5m / s or more; during high-speed reciprocating motion , the inner cutter head 6 and the outer cutter net 7 will continue to heat and wear; the continuous wear of the inner cutter head 6 and the outer cutter net 7 will cause problems such as reduced shaving sharpness, poor sound quality or even inability to shave
