Embodiment Construction

[0020] An example of a chassis is Figure 1~3 As shown: it includes a box body (not shown in the figure) provided with a dust removal device. The dust removal device includes a motor 1. The motor has a motor shaft whose axis extends along the front and rear directions. A fan is arranged on the motor shaft. The fan includes The fan base 2 and three fan blades 9 evenly distributed on the outer periphery of the fan base, the front end of each fan blade is fixed with a negative pole net 7, and the front end of the fan blade is also fixed with a positive electrode adsorption layer corresponding to each negative pole net 8. The areas of the negative grid and the positive adsorption layer are both smaller (or equal) to the area of ​​the corresponding fan blade. Each positive adsorption layer is insulated from the corresponding negative grid. Each positive adsorption layer is located on the back side of the corresponding negative grid. The positive adsorption layer consists of It cons...

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. ...
