Electric shaver: Use electric power to drive the blade, shaving the beard and bursting the cosmetic. It was introduced in the United States in 1930. Electric shavers are divided into rotary and reciprocating types according to the blade action mode. The former has a simple structure, a small noise, and a moderate shaving force; the latter has a complicated structure and a large noise, but has a large shaving force and a high sharpness. The rotary electric shaver can be divided into a straight type, an elbow type, a charged push-pull type and a double-head type according to the outer shape structure. The first two structures are simpler and the latter two are more complicated. Electric shavers can be divided into DC permanent magnet motor type, AC/DC dual-purpose series excitation motor type and electromagnetic vibration type according to the prime mover type.
