Abstract
An electric shaver incorporating an elastomeric, unitary, diaphragm suction pump driven from an eccentric off the cutting blade driving motor. A channel is formed about the cutting head in communication with the suction pump. During shaving, the suction pump creates a partial vacuum in the channel about the cutting head whereby the skin is drawn into the channel and, thereby, stretched across and against the cutting head. Axial sliding of the cutting head and/or a collar surrounding the channel can be employed in addition to provide self-adjustability.
