[0036] Embodiment 1:

[0037] The utility model proposes a self-cleaning air purifier. When in use, the exhaust fan 2 is started, and the exhaust fan 2 extracts the outside air through the exhaust pipe 21, and then discharges the air into the interior of the filter cover 3 through the exhaust pipe 22 and the upper hose 32. The air entering the interior of the filter cover 3 is discharged to the outside of the filter cartridge 1 through the exhaust holes on the surface of the filter cover 3 and the protective plate 11. When the particulate dust contained in the air passes through the exhaust holes of the filter cover 3, it is filtered by the filter cover 3 and retained in the interior of the filter cover 3. Since the filter cover 3 is set as an inverted bucket structure, the dust retained in the interior of the filter cover 3 falls into the interior of the ash collecting hopper 31 under the action of gravity.

[0038] By configuring the filter cover 3 as an inverted bucket-shaped structure and providing an ash hopper 31 below the filter cover 3, the dust accumulated inside the filter cover 3 falls into the ash hopper 31 under the action of gravity, thereby avoiding the problem of large-scale accumulation of dust on the inner wall of the filter cover 3 causing blockage of the exhaust holes, and at the same time, the dust is quickly collected by the ash hopper 31.

[0039] Embodiment 2:

[0040] On the basis of the first embodiment, when the exhaust fan 2 extracts air through the exhaust pipe 21, the air enters the exhaust pipe 21 through the inlet of the mounting pipe 13. During the process, the airflow drives the driving shaft 7 to rotate through the driving impeller 71, and the driving shaft 7 drives the rotating plate 6 to rotate through the driving gear 72 and the driven gear 62. During the rotation of the rotating plate 6, the end of the flip rod 4 away from the knocking head 42 is pressed downward through the guide block 61 and the roller 43, so that the knocking head 42 is tilted. When the roller 43 passes over the guide block 61, the knocking head 42 quickly falls to the surface of the protective pad 35 under the action of gravity, knocking the filter cover 3, causing the filter cover 3 to vibrate, thereby shaking off the dust adhering to the inner wall of the filter cover 3 and entering the exhaust hole of the filter cover 3;

[0041] The airflow extracted by the exhaust fan 2 drives the rotating plate 6 to rotate, so that the rotating plate 6 drives the knocking head 42 to knock on the filter cover 3 through the guide block 61, causing the filter cover 3 to vibrate, thereby promoting the dust inside the filter cover 3 to fall into the ash collecting hopper 31, thereby ensuring the filtering effect of the filter cover 3 on the air.

[0042] Working principle: An air purifier is a device that can filter and purify indoor air. The utility model proposes a self-cleaning air purifier. When in use, the exhaust fan 2 is started, and the exhaust fan 2 draws outside air through the exhaust pipe 21, and then discharges the air into the interior of the filter cover 3 through the exhaust pipe 22 and the upper hose 32. The air entering the filter cover 3 is discharged to the outside of the filter cartridge 1 through the exhaust holes on the surface of the filter cover 3 and the protective plate 11. The particulate dust contained in the air is filtered by the filter cover 3 when passing through the exhaust holes of the filter cover 3, and is retained in the interior of the filter cover 3. Since the filter cover 3 is arranged as an inverted bucket structure, the dust retained in the interior of the filter cover 3 falls to the dust collector under the action of gravity. Inside the bucket 31, when the exhaust fan 2 draws air through the exhaust pipe 21, the air enters the exhaust pipe 21 through the inlet of the mounting tube 13. During the process, the airflow drives the drive shaft 7 to rotate through the driving impeller 71, and the drive shaft 7 drives the rotating plate 6 to rotate through the driving gear 72 and the driven gear 62. During the rotation of the rotating plate 6, the end of the flip rod 4 away from the knocking head 42 is pressed downward through the guide block 61 and the roller 43, so that the knocking head 42 is tilted. When the roller 43 passes over the guide block 61, the knocking head 42 quickly falls to the surface of the protective pad 35 under the action of gravity, knocking the filter cover 3, causing the filter cover 3 to vibrate, thereby shaking off the dust adhering to the inner wall of the filter cover 3 and entering the exhaust hole of the filter cover 3.
