Description

Rotary inner cutter

Technical Field

The utility model relates to a rotary inner knife.

Background

Electric razor: the electric appliance device for shaving beard and hair is characterized in that the blade is driven by electric power. According to the movement principle of the inner blade, the electric shaver is divided into two types of rotary type and reciprocating type according to the blade action mode. The reciprocating shaving system shaves beards through the left and right reciprocating motion of the cutter head, and the cutter head is accelerated and decelerated continuously in the reciprocating motion, so that the vibration and the noise are high during use; the rotary shaving system rotates in the center, and circular motion can continuously and unidirectionally shave beards without causing pulling discomfort and with low noise. Most of the rotary inner cutters on the market are formed by combining three inner blades with the same size or by combining a plurality of vertical cutter bars, and the arrangement has the following problems. Firstly, when long beard is removed, the problem of root tip residue is easy to occur, the repulsive force is easy to increase when more roots are left, and if the problem of root residue is eliminated by reducing the angle of the blade tip, the repulsive force is increased to reduce the shaving efficiency. The integral manufacturing process of the multi-strip rotary inner cutter is complex, and compared with a blade type, the safety problems such as breakage and the like are easier to occur. And thirdly, the multi-strip type rotary inner cutter has low shaving coverage rate and low shaving efficiency.
