The force required for the tension spring 214 to be stretched is greater than the force required for the suspension spring 211 to be stretched, so that when the center linkage shaft 207 moves downward, the gas seal pressure cover 210 descends first.

[0033] An electromagnetic top bin 215 is fixedly provided at the upper end of the central linkage shaft 207, and a compression outer tube 216 is fixedly provided on the lower surface of the electromagnetic top bin 215. The compression outer tube 216 is covered on the outside of the central linkage shaft 207, and an anti-slip bottom eave 217 is fixedly provided on the outer surface of the compression outer tube 216 near the lower end. The anti-slip bottom eave 217 is located below the pressure cover 3, and an impact tube 218 is sleeved and installed between the central linkage shaft 207 and the compression outer tube 216. A split connecting shaft 219 is fixedly provided on the upper end surface of the impact tube 218.

[0035] An air outlet slot 301 and an air inlet hole 302 are provided on the surface of the pressure cover 3. The air outlet slot 301 corresponds to the position of the ozone filter element 5, and the air inlet hole 302 corresponds to the position of the central generating tube 2. A heat conducting fin 701 is fixedly provided on the upper surface of the heat conducting plate 7. A wire hole 702 is provided on the surface of the heat conducting plate 7. A carbon fiber release needle 801 is fixedly provided on the inner surface of the electron release ring 8. A connecting wire 802 is provided for the external connection of the electron release ring 8. The DC negative high voltage power supply 6 is conductively connected to the carbon fiber release needle 801 via the connecting wire 802.

[0036] When the present invention is in use, the DC negative high-voltage power supply 6 is energized, and the DC negative high-voltage power supply 6 generates a DC negative high voltage. By conducting the connecting wire 802, the carbon fiber release needle 801 is charged, and electrons are released through the carbon fiber release needle 801, so that negative oxygen ions are formed in the air.

[0037] During the above process, the axial flow fan 9 is running, driving the air flow to flow in from the air inlet 302, and after being filtered by the air intake dust filter device, the gas flows through the carbon fiber release needle 801 to form negative oxygen ions and ozone, and then the ozone is removed by the ozone filter element 5, and the air containing a large amount of negative oxygen ions is discharged to the outside through the air outlet slot 301; when the DC negative high-voltage power supply 6 works for a long time and generates heat, such as Figure 6 As shown in the figure, the DC negative high-voltage power supply 6 conducts heat to the heat-conducting plate 7, causing the heat-conducting plate 7 to heat up. When the gas flows through the heat-conducting fins 701, it can be heated, thereby increasing the molecular activity of ozone in the gas and improving the decomposition efficiency of ozone. At the same time, the DC negative high-voltage power supply 6 is cooled, thereby extending the life of the DC negative high-voltage power supply 6.

[0038] In the above process, when the air intake dust filter device is working, the gas flows in through the air inlet hole 302, and then flows from the outside of the corrugated filter paper 204 to the inside of the corrugated filter paper 204. The gas passes through the corrugated filter paper 204, so that the dust stays on the outer surface of the corrugated filter paper 204, and then the dust-free airflow continues to flow downward, passing through the suspension ring platform 209 and the sealing ring platform 208 in turn to reach the carbon fiber release needle 801.

[0039] When self-cleaning is performed, the driving module 224 is in operation, and drives the compression outer tube 216 to move downward by meshing with the rack ridge 223. At the same time, a pulse current is passed through the electromagnet 222 to generate intermittent magnetic force, and by cooperating with the stabilizing suspension spring 221, the magnetic suction cup 220 moves up and down, thereby driving the impact tube 218 to move up and down. In the process of the compression outer tube 216 moving downward, the central linkage shaft 207 moves downward synchronously. Since the force required for the tension spring 214 to be stretched is greater than the force required for the suspension spring 211 to be stretched, when the central linkage shaft 207 moves downward, the air seal pressure cover 210 descends first, and the air seal pressure cover 210 cooperates with the sealing ring 208 to close the bottom of the corrugated filter paper 204, so that the corrugated filter paper 204 cooperates with the inner wall of the central generating tube 2 to form a closed structure. As the compression outer tube 216 continues to move downward, the lower end of the compression outer tube 216 is pressed against the upper surface of the hard top cover 206, gradually compressing the corrugated filter paper 204, which can cause positive pressure inside the corrugated filter paper 204, thereby causing the gas to flow in the opposite direction and blow out the dust in the gaps on the surface of the corrugated filter paper 204; at the same time, the impact tube 218 impacts up and down, performing high-frequency hammering on the upper surface of the hard top cover 206, causing the corrugated filter paper 204 to vibrate at a high frequency while venting air in the opposite direction, discharging the dust into the storage ring bin 203, thereby effectively achieving self-purification.
