According to needs, manually pull the inner rod to stretch it along the groove until the pad is stuck in the upper limit hole to fix the position of the inner rod; close the splash guard, cover the top cover, and blow and clean the filter cartridge by switching the water regulating valve and the compressed air regulating valve. The clean water is transported to the spray pipe and the nozzle on the cleaning ring through the water storage tank to clean the filter cartridge. The sewage passes through the porous plate and the collection plate in turn, and finally overflows to the water filter through the water outlet. After filtration, it returns to the water storage tank for reuse. After the water washing is completed, the air compressor pump transports compressed air into the spray pipe through the pipeline to blow the water on the filter cartridge dry.

[0014] Among them, the clean water and compressed air on this device can be supplied from the outside, and it is only necessary to connect the pipeline to the device that provides the water source or air source; at the same time, in order to ensure the smoothness of the pad when the positioning rod is extended and retracted, the pad is in the shape of a bullet head, with a smooth surface and easy to slide. After use, you only need to press the inner rod until the pad is stuck in the bottom limit hole.

[0015] The beneficial effects of the utility model are as follows: by arranging a spray cleaning pipe, cleaning water and compressed air are combined to make cleaning more thorough, and at the same time, the tray is designed in layers to ensure that the bottom of the filter cartridge does not need to be immersed in water, thereby extending the service life of the filter cartridge; by filtering sewage, the waste of cleaning water is reduced; finally, by the telescopic design of the filter cartridge placement slot and the positioning rod, the stability of the cleaning process is ensured, and the device structure is reasonably laid out, which not only improves the cleaning efficiency of the filter cartridge, but also reduces the replacement cost.
