Description

TECHNICAL FIELD

[0001] The present application relates to the field of shavers, in particular to a shaver with a head combination of forward and reverse rotating screens. BACKGROUND

[0002] Electric shavers are personal grooming appliances that use electric power to drive a blade to cut hair. An electric shaver is composed of a stainless steel screen, an inner blade, a micro motor and a housing. The screen, which is a fixed outer blade, has a number of holes through which hair can be inserted. The micro motor is driven by electric power to drive the inner blade to cut the hair inserted into the holes by using the shearing principle. Conventional electric shavers can be divided into rotary and reciprocating types according to the action characteristics of the inner blade. The power sources used include dry batteries, storage batteries and alternating current chargers.

[0003] Such shavers usually only use the user to make the screen contact with the skin, and then the inner blade cuts the hair. The insertion of the hair into the screen holes relies entirely on the pushing of the hand. The shaver itself lacks the ability to actively capture hair. In the face of different hair conditions of the user, the hair into the screen is passive and inefficient. The use will find that there is a problem of insufficient hair capturing function, resulting in low efficiency and poor effect in the shaving process. In order to improve this aspect, the efficiency of the shaver to capture hair is improved, and a shaver with a head combination of forward and reverse rotating screens is proposed. SUMMARY
