Among these air purification equipment, most of them need to use filters to filter the air.

[0003] After retrieval, the publication number is CN116510428A, which discloses a filter that can be cleaned and reused. When cleaning the wire mesh filter layer, water will flow out of the water inlet pipe. Since the water outlet of the water inlet pipe is arranged on one side of the wire mesh filter layer, when the water inlet pipe discharges water, one side of the wire mesh filter layer will deflect under the impact of the water flow. Through the continuous impact of the water flow, the rotation of the wire mesh filter layer can be realized. At the same time, under the action of the water flow, the viscous particulate matter on the wire mesh filter layer can be further separated from the wire mesh filter layer.

[0004] In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved: only the surface layer of the filter screen can be rinsed, the cleaning effect is limited, and after the filter screen is cleaned, a large amount of water stains will adhere to the surface, affecting subsequent filtering operations.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows. When the solenoid valve is opened, the water in the high-pressure water pipe can be introduced into the water guide groove and evenly discharged to the housing through the water spray holes, so as to wash the filter screen in the housing.
