The invention relates to a dust collecting device, especially an electrostatic dust collecting device.

According to the working principle of the electrostatic dust collector, the gas with suspended particles passes through the air flow channel, and a dust collecting plate and a plurality of discharge electrodes are provided in the channel. The discharge electrode and the dust collecting plate have opposite polarities. When the discharge When there is sufficient DC voltage between the electrode and the dust collecting plate, the discharge electrode will ionize the gas molecules in the air, causing the dust in the airflow to be charged, forming positive and negative ions.

Magnified diagram of the tip. This creation is an electrostatic dust collecting device. The electrostatic dust collecting device 1 mainly includes: an electrode device 10, a substrate 11, a first nickel foam mesh 12, a second nickel foam mesh 13 and a device 14. The electrode device 10 includes a positive electrode 100 and a negative electrode. 102. The substrate 11 (hard circuit board or flexible circuit board) is connected to the positive electrode 100 and the negative electrode 102 respectively. The first nickel foam mesh 12 is connected to the substrate 11 that is connected to the positive electrode 100. The first nickel foam mesh 12 at least includes a plurality of hole structures 122. The second nickel foam mesh 13 is connected to the substrate 11 that is connected to the negative electrode 102. The second nickel foam mesh 13 at least includes a plurality of multi-directional tips 130. After the positive electrode 100 and the negative electrode 102 are energized, they pass through the first nickel foam mesh 12 to the second nickel foam mesh. 13 generates a voltage difference, causing the multi-directional tip 130 of the second nickel foam mesh 13 to discharge the plurality of hole structures 122 of the first nickel foam mesh 12 to expand the adsorption range of the nickel foam mesh, and at the same time, each hole structure 122 collects dust, and the device 14 mainly includes a base 140 and a cover 142 provided on the base 140, and forms a receiving space 144 for accommodating the electrode device 10, the substrate 11, the first nickel foam mesh 12 and the second nickel foam mesh 13.

Since the substrates 11 respectively connected to the positive electrode 100 and the negative electrode 102 are arranged side by side, the first nickel foam mesh 12 is placed above each substrate 11. The first nickel foam mesh 12 is fixed to the substrate 11 by welding and connected to the positive electrode 100. The part located above the substrate 11 that conducts the negative electrode 102 is fixed to the substrate 11 by welding but is not connected to the negative electrode 102. As for the second nickel foam mesh 13, the method is the same as the first nickel foam mesh 12, but the welding position is opposite. The second nickel foam mesh 13 is fixed to the substrate 11 by welding and is connected to the negative electrode 102 , while the portion above the substrate 11 that is connected to the positive electrode 100 is fixed to the substrate 11 by welding but is not connected to the positive electrode 100 .

In addition, the first nickel foam mesh 12 and the second nickel foam mesh 13 are provided with filters 16 on both sides.

It can be seen from the above implementation modes that since the electrostatic dust collector 1 of the present invention is mainly used in air conditioning equipment or air purifiers, when the equipment becomes larger, the size of the electrostatic dust collector 1 must also be increased or increased depending on the demand. Increasing the number, since the first nickel foam mesh 12 and the second nickel foam mesh 13 can generate corona, can effectively expand the adsorption of particles, bacteria, and virus charges in the air through the action of Coulomb force, effectively optimizing the general traditional filtration in the past. The fixed range of the net even has no significant filtering effect on bacteria and viruses.

Furthermore, only the first nickel foam mesh 12 and the second nickel foam mesh 13 are needed to replace the traditional discharge electrode and dust collecting plate, greatly reducing the size and greatly reducing the overall electrostatic dust collection device with a simple structure.
