A cleaning component for cleaning the outer wall of the cylindrical filter element 5 is provided on the inner wall of the fixed ring 14. The right side of the sliding seat 13 extends into the automatic cleaning area 8 and is provided with a connecting portion 15. A lifting device is also provided in the automatic cleaning area 8. When the cylindrical filter element 5 is located in the ventilation and filtration area 7, the right side plate 12 seals and separates the ventilation and filtration area 7 from the automatic cleaning area 8. When the cylindrical filter element 5 is located in the automatic cleaning area 8, the left side plate 11 seals and separates the ventilation and filtration area 7 from the automatic cleaning area 8, and the connecting portion 15 is connected to the lifting device.

[0029] According to the above structure, by dividing the interior of the lower shell 2 into a ventilation and filtration area 7 and an automatic cleaning area 8, and cooperating with the left and right sliding of the sliding bottom plate 9, the cylindrical filter element 5 can be switched between the ventilation and filtration area 7 and the automatic cleaning area 8. When the filter element needs to be cleaned, it is slid into the automatic cleaning area 8 for automatic cleaning, thereby eliminating the need for manual cleaning and saving time and effort.

[0030] The cleaning component on the inner side of the fixed ring 14 can perform circumferential cleaning along the outer wall of the cylindrical filter element 5. Combined with the lifting device, the lifting movement of the sliding seat 13 is driven to cover the entire surface of the cylindrical filter element 5, and the cleaning effect is better. The left and right side plates form a dynamic sealing isolation when the cylindrical filter element 5 is switched to prevent pollutants in the cleaning area from flowing back into the purified air duct, thereby ensuring the quality of purified air. At the same time, there is no need to frequently replace the filter element or perform complicated operations, which significantly reduces the cost of consumables and the frequency of manual maintenance.

[0031] In the present invention, a longitudinal slide groove is provided on the right side plate 12, and the sliding seat 13 includes a slider 22 that slides up and down in the longitudinal slide groove. A mounting seat 23 is provided on the slider 22, and the fixed ring 14 and the connecting part 15 are respectively provided on the mounting seat 23. The matching design of the longitudinal slide groove and the slider 22 makes the up and down movement of the sliding seat 13 on the right side plate 12 more stable, avoids the displacement or jamming of the cleaning component, and improves the reliability of the cleaning action.

[0032] Furthermore, an upper accordion seal 31 is connected to the upper end of the slider 22 and the longitudinal slide groove, and a lower accordion seal 32 is connected to the lower end of the slider 22 and the longitudinal slide groove. The upper and lower accordion seals cover the gap between the slider 22 and the longitudinal slide groove, effectively isolating the dust in the automatic cleaning area 8 from entering the ventilation and filtration area 7.

[0033] In the present invention, the cleaning component includes a rotating ring 41 arranged on the inner side of the fixed ring 14, and a cleaning brush 42 is arranged on the inner side of the rotating ring 41; the cleaning brush 42 is arranged on the inner side of the rotating ring 41, and the outer wall of the cylindrical filter element 5 is brushed in all directions through the rotating motion, so as to achieve deep cleaning of the filter material folds or curved surface structure and improve the dust removal efficiency.

[0034] Furthermore, the rotating ring 41 is coaxially arranged with the fixed circular ring 14, and the rotating ring 41 is rotatably arranged on the inner wall of the fixed circular ring 14, and a transmission assembly is also arranged on the right side plate 12, and when the slider 22 slides up and down along the longitudinal slide groove, the rotating ring 41 can be driven to reciprocate in positive and negative directions through the transmission assembly; the transmission assembly converts the up and down linear motion of the slider 22 into positive and negative reciprocating rotation of the rotating ring 41, and the bidirectional cleaning action of the brush can be realized without an additional power source, thereby reducing energy consumption and structural complexity.

[0035] At the same time, the forward and reverse cleaning modes can avoid the dust accumulation problem caused by one-way brushing and enhance the cleaning effect.
