Abstract

The invention discloses a dustproof electric tool which comprises a shell, a dustproof sleeve, blades, a drill chuck and a drill bit. A motor and a transmission mechanism are arranged in the shell; the drill chuck is arranged at the front part of the shell; the motor drives the drill chuck to rotate; the drill bit is arranged in the drill chuck; an annular inserting groove is formed in the front part of the shell; the dustproof sleeve comprises an inner cylinder and an outer cylinder; the inner cylinder is inserted into the outer cylinder and can move in the axial direction of the outer cylinder; the outer cylinder is inserted into the annular inserting groove; and the blades are arranged on the drill chuck. According to the dustproof electric tool provided by the invention, airflow is generated through the blades, so that dust emerging from a drilled hole flies, and the dust is prevented from falling along the wall to pollute the wall; and meanwhile, the inner cylinder and the outer cylinder are arranged to limit raised dust in the inner cylinder and the outer cylinder, so that raised dust on a construction site is reduced.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to a dustproof electric tool. Background technique [0002] A hand-held electric drill is a commonly used electric tool in the decoration industry, mainly used for drilling holes in walls or floors. During house decoration, some equipment and household products are after-installation products, such as air conditioners, bathroom cabinets, curtains, wall lamps, and decorative paintings. These after-installation products are often installed after the hard decoration of the house is completed. It is necessary to drill holes on the painted wall; the drill bit will produce some very fine powder ash when drilling, which is produced by the friction between the drill bit and the masonry wall. Depending on the specific wall material, the powder ash It may be gray, silver, cyan or red. The powder ash comes out along the spiral groove of the drill bit and then falls against the wall from the dril...
