Abstract
A self-cleaning dry shaver is disclosed having a reel-type rotary blade and a retractable guard for the perforated shear plate. With the guard retracted, cuttings and other debris removed during the shaving procedure are collected in a chamber within the dry shaver housing. After use, and while the blades are rotating, the retractable guard is withdrawn from the shaver housing to cover and close the perforated shear plate, while opening axial air inlet ports. Simultaneously with this act, the cuttings and other shaving debris are expelled from the collection chamber to the atmosphere through a conduit which is opened by withdrawal of the retractable guard from the shaver housing.
