[0034] Working principle: when waste water enters the filter tank 1 through the water inlet pipe 2, it will contact the filter screen 8 on the connecting ring 6, so that the filter screen 8 can filter the impurities of the waste water entering the filter tank 1, so that the filtered impurities remain on the filter screen 8, and the filtered waste water is discharged from the filter tank 1 through the outlet pipe 3. By starting the motor 12 on the connecting cover 10, the started motor 12 drives the connecting rod 13, the first connecting plate 14, the second connecting plate 15 and the support rod 17 to rotate with the connecting rod 13 as the central axis. At the same time, the rotating first connecting plate 14 and the second connecting plate 15 will drive the elastic brush 16 to rotate in contact with the filter screen 8, so that the elastic brush 16 can clean the surface of the filter screen 8, thereby reducing the probability of the filter screen 8 being blocked. By pulling the second plug block 27, the movable second plug block 27 drives the limiting rod 25 and the slider 26 to move. When the movable second plug block 27 is disengaged from the limiting groove 29 on the flip block 22, the restriction on the torsion spring 32 can be released, so that the torsion spring 32 flips and rebounds, so that the flipped and rebounded torsion spring 32 drives the rotating rod 21 to rotate, so that the rotating rotating rod 21 drives the flip block 22 and the first plug block 23 to rotate with the rotating rod 21 as the central axis. When the rotating first plug block 23 is disengaged from the fixing groove 28, the fixation between the L-shaped block 19 and the fixing block 24 is released, and then the fixation between the filter tank 1 and the connecting cover 10 is released, and the flipped first plug block 23 will not affect the subsequent filter tank 1 and the connecting cover 10. The connection between the filter tank 1 and the filter screen 8 is removed by lifting the handle 11, and then the connection cover 10 and other devices on the connection cover 10 can be removed from the filter tank 1, and the filter screen 8 in the filter tank 1 can be exposed. Then the handle 7 is pulled upward, so that the connection ring 6 and the filter screen 8 can be removed from the limit ring 4 on the filter tank 1, and then the elastic brush 16 and the filter screen 8 can be cleaned. When the filter screen 8 and the elastic brush 16 are cleaned, the positioning block 5 on the connection ring 6 is inserted into the positioning groove 9 on the limit ring 4, so as to realize the connection between the filter tank 1 and the positioning groove 9, and then the fixing block 24 on the connection cover 10 is placed on the L-shaped block 19, so that the first plug block 23 corresponds to the fixing groove 28, and then the second plug block 27 is pulled to move the second plug block 27 drives the limiting rod 25 and the slider 26 to move, and the moving second plug-in block 27 will not affect the flipping of the flip block 22 and the first plug-in block 23. At the same time, the moving slider 26 will squeeze the spring 31 on the slide slot 30, so that the spring 31 is in a taut state, and then the flip block 22 is flipped, so that the flip block 22 and the first plug-in block 23 rotate with the rotating rod 21 as the central axis, and the rotating rod 21 can be rotated, so that the rotating rotating rod 21 pulls the torsion spring 32 on the connecting block 20, so that the torsion spring 32 is in a flipped and stretched state. When the flipped first plug-in block 23 is inserted into the fixed groove 28, the limiting groove 29 can correspond to the second plug-in block 27, and then the pulled second plug-in block 27 is released, so that the spring 31 is no longer restricted and rebounds.Thus, the rebound spring 31 drives the limiting rod 25, the slider 26 and the second plug block 27 to move, so that the second plug block 27 can be quickly inserted into the limiting groove 29, so as to limit the torsion spring 32, so that the torsion spring 32 will not flip and rebound, and then the first plug block 23 can be kept in the fixing groove 28 and will not fall out, so as to complete the fixation between the L-shaped block 19 and the fixing block 24, and realize the fixation between the filter tank 1 and the connecting cover 10, so that the equipment on the connecting cover 10 can be located inside the filter tank 1.
