Abstract
A cordless hair trimmer has a reciprocating blade system adapted for delicate trimming in small, sensitive body areas such as the eyebrows, ears and nose. An air inlet is provided adjacent to the blades, and a vacuum is created at the air inlet by a suction fan inside the trimmer. The fan draws air through the inlet to a chamber at the bottom of the device, where hair clippings are collected until a clean-out door is removed and the chamber is emptied. The fan also creates air pressure at the blades which inhibits the accumulation of cut hair strands in the blades and blade mechanism.
