Abstract

The invention provides an electric tool with a dustproof device and a dustproof method, the dustproof device is arranged in an air cavity in a shell of the electric tool, the dustproof device comprises an electrified degaussing magnet, and at least part of the electrified degaussing end is arranged in the air cavity; whether the electrified demagnetizing end has magnetism or not is controlled by judging whether the controller applies voltage to the voltage output end of the electrified demagnetizing magnet or not, so that the effect that the electric tool automatically adsorbs metal dust at the air inlet and removes the metal dust is achieved, and the metal dust is prevented from entering the motor to damage the function and the service life of the motor. Furthermore, the magnetism of the electrified demagnetization end is controlled by the controller, so that manual operation is not needed, the metal dust can be intelligently discharged, and the service life of the electric tool is prolonged.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to an electric tool with a dustproof device and a dustproof method. Background technique [0002] Compared with brushed motors, permanent magnet brushless motors have the characteristics of simple structure, small size, high efficiency, and long life. They are currently widely used in various industries, especially in the power tool industry. Compared with traditional brushed motors, they have carbon-free With the characteristics of brushing dust, no sparks, low noise, no wear, high work efficiency, and long life, it has solved the problems that traditional power tools have been troubled and unable to break through for a long time, and has attracted more and more attention and recognition from consumers. The structure of the permanent magnet brushless motor is mainly composed of a stator with windings and a rotor embedded with permanent magnets. The structure and manufacturin...
