Dustproof device and electric hand drill

Abstract

The invention relates to a dustproof device special for an electric hand drill and the electric hand drill applying the dustproof device. The dustproof device comprises a dustproof cover and a dust discharging plate, wherein the dustproof cover is a bowl-shaped casing formed by a bottom, a peripheral wall and an open end. The center of the bottom protrudes towards the open end to form an annular dust collection chamber between the protruded top end and the peripheral wall, and a through hole penetrating through the bottom and used for being in clearance fit with a drill bit is arranged at the protruded top end. The dust discharging plate is an umbrella-shaped round plate, and the center of the round plate is provided with a locking hole fixed relative to the drill bit. By means of the electric hand drill applying the dustproof device, dust explosion in the hole drilling process is eliminated, and environment pollution and physical and psychological harm caused by the dust produced by hole drilling can be effectively avoided.
