Depilatory device

Abstract

A depilatory device in this invention comprising a housing, a plucking means, a pinching mechanism, and a plucking mechanism. The plucking means includes a plucking cylinder which is supported to the housing. The plucking cylinder carries a plurality of pinching units at a circumference surface of the plucking cylinder. The pinching unit is composed of a first blade and a second blade. At least one of the first blade and the second blade is movable toward and away from the other of the first blade and the second blade to have an opened position and a pinch position. Each of the pinching units has a hair introducing direction perpendicular to the gap between the first blade and the second blade in the opened position. The pinching mechanism is configured to provide the opened position and the pinch position to the first blade and the second blade. The plucking mechanism is configured to rotate the plucking cylinder. The pinching units are arranged to have their hair introducing directions which are inclined with respect to the longitudinal axis as well as a circumferential direction of the plucking cylinder.
