Dust removing device and chassis adopting dust removing device

Abstract

The invention relates to a dust removing device and a chassis adopting the dust removing device. The dust removing device comprises a motor; the motor is provided with a motor shaft of which the axis extends in the front-back direction; a fan is fixed on the motor shaft; cathode nets are fixed on the front ends of all blades of the fan; anode adsorption layers in insulation match with the corresponding cathode nets are fixed between all the cathode nets and corresponding blades of the fan; the fan is further provided with a first rotation electric connection structure for electrically connecting all the cathode nets with corresponding cathode power supplies and a second rotation electric connection structure for electrically connecting all the anode adsorption layers with corresponding anode power supplies. The invention provides the dust removing device with a compact structure.

Description

technical field [0001] The invention relates to a dust removal device and a cabinet using the dust removal device. Background technique [0002] After the computer is used for a long time, the dust in the chassis will be adsorbed on the power supply, memory, fan, various boards and other components. The fan is blocked; the dust adsorbed on the radiator will affect the heat dissipation quality of the radiator and the stability of the whole machine; the dust adsorbed on the board will easily lead to poor contact of the board. Therefore, a corresponding dust removal device is required to remove dust inside the chassis. An existing dust removal device such as the "electrostatic precipitator" disclosed in Chinese patent CN201632328U includes a fan and a motor. The fan blade seat is fixed on the motor shaft of the motor, a positively charged adsorption frame is arranged in front of the fan, and a negatively charged negative pole net is arranged in front of the adsorption frame. ...

AI Technical Summary

Problems solved by technology

The problem with the existing dust removal device is that the adsorption frame, the negative grid, and the fan blades are set independently, which makes the structure of the entire dust removal device not compact enough and takes up a large space for use. It is used in various occasions, especially the equipment with very limited space such as the chassis. Since the electrostatic precipitator occupies a large space, it will affect the heat dissipation inside the chassis, and it is also not conducive to the miniaturization of the chassis.
