An electric shaver has a reciprocating blade assembly beneath a perforated foil and the surrounding space is filled with foam material except for the blade movement space so that air is pumped through the foil to cool the skin of the user

摘要

The reciprocating blade assembly (28) oscillates in a cavity (24) beneath a perforated foil (12) and the space is filled with a foam material (39) with the exception of the space (41) into which the blade assembly moves so that at each oscillation air is squeezed through the foil perforations.
