[0013] The present invention has the following beneficial effects: When the motor of the present invention is turned on, the output end will drive the threaded rod to rotate through the rotating rod. When the threaded rod rotates, it will drive the lifting frame to move up and down, thereby driving the spray washing cylinder to move up and down. This allows the spray washing cylinder to more thoroughly rinse the filter material during the backwashing process. When the water pump is turned on, the output end will discharge the filtered water inside the circulating water tank into the interior of the annular nozzle through the circulating hose via the water suction pipe. The water will then be sprayed out under high pressure to complete the backwashing process. The water inside the annular nozzle will enter the interior of the spray washing cylinder through the hose, thereby backwashing the filter material. The spring plate limits and resets the circulating hose, making the machine more stable during the backwashing process.

[0014] When the threaded rod of this invention rotates, it drives the second rotating rod to rotate. This second rotating rod, in turn, drives the cleaning push plate and scraper to rotate, allowing them to scrape and clean the filter plate and the inner wall of the impurity collection box. As the cleaning push plate rotates, it compresses and causes the sliding plate to slide inside the chute, pushing impurities through the chute into the collection tank for centralized collection. Simultaneously, as the sliding plate moves, it moves the moving block and the squeezing plate. The squeezing plate compresses the impurities inside the collection tank, expelling any water mixed in and discharging it through the filter holes. The elastic bending rod ensures greater stability as the squeezing plate and moving block move, and simultaneously pulls the moving block to reset the sliding plate, preventing the collected impurities from floating out due to backflow.

[0015] When the threaded rod of this invention rotates, it drives the third rotating rod to rotate, which in turn drives the cleaning scraper and cleaning brush to rotate. This allows the cleaning scraper and cleaning brush to clean the filter material and the inner wall of the filter housing, respectively, preventing machine blockage caused by the long-term accumulation of fine particles. At the same time, when the rotating rod rotates, it drives the gear to rotate. The gear meshes and drives the rack to move back and forth on the surface of the limiting rod. The fixed telescopic rod makes the rack's position more stable when it moves, preventing positional deviation and jamming problems. Meanwhile, when the rack moves, it pushes the force plate above the filter plate through the push-pull rod. The filter plate will perform a second filtration of some remaining impurities, and the force plate will squeeze the impurities for easy collection. The telescopic rod makes the position of the force plate stable when it moves.
