The box cover 1032 is installed and disassembled by being threadedly connected with the coarse filter box 103, which is convenient for cleaning the coarse filter box 103. The water inlet pipe 102 transports the coarsely filtered water in the coarse filter box 103 into the interior of the filter tank 2 through the water inlet 101. The filter tank 2 filters out fine sand and gravel and other impurities in the water through the fine filter screen 204. The water delivery pipe 1 301 transports the finely filtered water into the fine filter chamber 3, and the filter layer 303 filters and intercepts fine impurities in the water. The water pump 4 pumps the water out through the water delivery pipe 2 401 to increase the water filtration rate. The filter screen 304 prevents the water pump 4 from having excessive suction force, which causes the filter layer 303 to separate from the filter drawer 302, and the valve is opened. 2501, the water pump 4 uses the outlet pipe 5 to transport the filtered water out. After the filter tank 2 completes water filtration, the rotating motor 202 drives the threaded adjustment rod 201 to make the connecting frame 203 displaced by threaded connection with the threaded adjustment rod 201 through the threaded adjustment hole. The connecting frame 203 is slidably connected with the limiting slide groove 2031 through the directional pulley 2032 to improve the stability of the movement of the connecting frame 203. The cleaning brush 2033 brushes the fine filter screen 204, and at the same time, the sand and gravel debris intercepted by the fine filter screen 204 is swept into the discharge pipe 2041 for cleaning, so as to avoid the sand and gravel debris from clogging the fine filter screen 204 and the filter element layer 303 and affecting the water filtration efficiency. The whole operation process is simple and convenient. Compared with the existing filtering device, the utility model can facilitate the cleaning of the sand and gravel debris generated after filtration through design, avoid clogging the filter element, affect the life of the filter element, improve the water filtration rate, and enhance the overall practicality.
