By driving the driving pulley 16 to rotate through the first driving motor 15, the driving pulley 16 rotates to drive the driven pulley 18 to rotate through the transmission belt 17, so as to drive the spray head 14 on the water pipe 13 to move up and down to backwash the filter screen 5, reducing the damage of the filter screen 5 caused by excessive blockage and wear, effectively extending the service life of the filter screen 5, reducing the frequency and cost of replacing the filter screen 5, and increasing the service life of the filter screen 5.

[0030] The filtering box body 1 is fixedly connected with a fixing frame 21, the fixing frame 21 is fixedly connected with a second driving motor 22, the output end of the second driving motor 22 is fixedly connected with a gear 23, the gear 23 is engaged with a rack 24, the rack 24 is fixedly connected with a slider 25, a chute 26 is arranged on the fixing frame 21, the slider 25 is slidably connected in the chute 26, a filter screen 5 is fixedly connected in the filtering box body 1, a diatomite layer 6 is fixedly connected in the filtering box body 1, a quartz sand layer 7 is fixedly connected in the filtering box body 1, an activated carbon layer 8 is fixedly connected in the filtering box body 1, the filtering box body 1 is fixedly connected with a liquid inlet 2, the filtering box body 1 is fixedly connected with a liquid outlet 3, the rack 24 is fixedly connected with a flow blocking plate 27, a baffle 4 is fixedly connected in the filtering box body 1, the flow blocking plate 27 is slidably connected on the baffle 4, a sluice 28 is arranged on the baffle 4, the threaded rod 19 is rotatably connected to the filtering box body 1, multiple groups of spray heads 14 are provided, the water storage tank 9 is fixedly connected to the filtering box body 1, and the water pump 11 is fixedly connected to the filtering box body 1.

The water is transported to the water pipe 13 through the folding hose 12. The water in the water pipe 13 is sprayed out through the nozzle 14 to clean the filter screen 5. Then, the first driving motor 15 is started. The first driving motor 15 drives the driving pulley 16 to rotate. The rotation of the driving pulley 16 drives the driven pulley 18 to rotate through the transmission belt 17. The rotation of the driven pulley 18 drives the threaded rod 19 to rotate. The rotation of the threaded rod 19 drives the threaded block 20 to move, thereby driving the nozzle 14 on the water pipe 13 to move up and down to backwash the filter screen 5, so that the damage of the filter screen 5 caused by excessive blockage and wear is reduced, the service life of the filter screen 5 is effectively extended, the frequency and cost of replacing the filter screen 5 are reduced, and the service life of the filter screen 5 is increased.
