The outer wall of the sealing ring 8 is in close contact with the inner wall of the dust box 1, and the four corners of the dust box 1 are integrally formed with arc chamfers 17. By providing the transparent plate 7, it is convenient for relevant users to observe the internal situation of the dust box 1 from the outside of the dust box 1. By providing the sealing ring 8, the sealing between the dust box 1 and the sealing ring 8 is improved. By providing the arc chamfer 17, the problem of the corners of the dust box 1 being easily scratched by the user is avoided, and the aesthetics is increased at the same time. A plurality of plug rods 9 are plugged on both sides of the dust box 1, and one end of the plug rod 9 is connected to the transparent plate 7 and The sealing ring 8 is plugged in, and a limit block 10 is installed at the other end of the insertion rod 9. A tension spring 11 is installed between the limit block 10 and the dust box 1 and is sleeved on the outside of the insertion rod 9. The tension spring 11 in the initial state makes the limit block 10 close to the dust box 1. The tension spring 11 in the initial state makes the insertion rod 9 insert into the transparent plate 7 and the sealing ring 8 through the limit block 10, thereby fixing the transparent plate 7 on the dust box 1. The human hand pulls the insertion rod 9 away from the sealing ring 8 through the limit block 10, thereby facilitating the disassembly of the transparent plate 7, and then facilitating the cleaning of the interior of the dust box 1 and the replacement of the first activated carbon fiber filter 206 and the second activated carbon fiber filter 207.

[0040] Working principle:

[0041] The driving end of the servo motor 201 is controlled to rotate forward and reversely, so that the rotating shaft 202 rotates clockwise or counterclockwise, so that the two single-sided racks 205 are respectively moved relative to or away from each other on the two guide rods 204 through the gear 203, so that the first activated carbon fiber filter 206 is located in the electrolyte when the second activated carbon fiber filter 207 filters the passing exhaust gas, or the second activated carbon fiber filter 207 is located in the electrolyte when the first activated carbon fiber filter 206 filters the passing exhaust gas, and the first activated carbon fiber filter 206 or the second activated carbon fiber filter 207 is soaked for a period of time to remove dust and purify it, so as to ensure its subsequent filtering effect. The subsequent filtering and purification effect of the exhaust gas is ensured, and the first activated carbon fiber filter 206 or the second activated carbon fiber filter 207 is dust-removed and purified by immersion. The first activated carbon fiber filter 206 or the second activated carbon fiber filter 207 can operate continuously and effectively without replacement, which not only reduces the maintenance cost but also improves the efficiency of the dust removal operation, because there is no need to frequently replace the first activated carbon fiber filter 206 or the second activated carbon fiber filter 207, thereby ensuring that the operating time of the dust collector can be extended, and at the same time, the downtime caused by replacing the first activated carbon fiber filter 206 or the second activated carbon fiber filter 207 is reduced.
