The brackets 402 are elastic and can clamp and fix the coarse filter element 1, the high voltage electrostatic device 2 and the coupling catalyst element 3 respectively, so as to achieve a detachable connection with the outer shell frame 4.

[0030] Furthermore, the pallet 6 is L-shaped, and two U-shaped feet 601 are connected to the side of the pallet 6 away from its bend. A crossbeam 406 is connected between the two side plates 403. The bottom surface of the pallet 6 is in frictional contact with the crossbeam 406. A limit post 405 is connected to the side of the side plate 403 away from the crossbeam 406.

[0031] Furthermore, the high-voltage electrostatic device 2 includes a conductive frame 203, within which multiple high-voltage fins 204 and multiple grounding fins 206 are stacked. The high-voltage fins 204 and grounding fins 206 are staggered to form fin assemblies. Tungsten wire assemblies are provided on both sides of the fin assembly. The tungsten wire assembly includes an upper electrode plate 205 insulatedly connected to the upper end of the conductive frame 203 and a lower electrode plate 201 insulatedly connected to the bottom end of the conductive frame 203.

At the same time, the high-voltage fins 204 are fixedly connected to the electrode rods 207 at equal intervals.

The coarse filter 1 intercepts hair and large dust particles in the air. Then, the high-voltage DC power supply 7 is connected to the power supply, creating a strong high-voltage electric field between the spiral tungsten wire 202 and the grounded fin 206, and also between the high-voltage fin 204 and the grounded fin 206.
