An oscillating frame 330 is arranged in the interior of the frame 310. A filter screen 331 is fixedly sleeved in the interior of the oscillating frame 330. The centers of the opposite sides of the oscillating frame 330 are rotatably connected to the centers of the opposite sides of the frame 310. A rotating plate 320 is fixedly connected to the top surface of the frame 310. The outer side wall of the rotating plate 320 is rotatably sleeved in the inner side of the top opening of the shell 100. Water outlets 301 are formed in the bottom surface of the frame 310 and the bottom surface of the shell 100. The driving mechanism 400 is located in the interior of the connecting ring 200.

[0025] Specifically, the automatic valve 500 is an automatic butterfly valve, an automatic gate valve, etc., which can be controlled to open and close by a PLC controller. A flange is connected to the two pipe bodies 110. One pipe body 110 is flange-connected to the automatic valve 500, and then the other pipe body 110 and the automatic valve 500 can be flange-connected to the water supply pipe. The direction of water flow is that the water flows through the two pipe bodies 110 in sequence and then passes through the automatic valve 500, and the water flows through the inside of the housing 100 and is filtered by the filter mechanism 300. When the filter mechanism 300 is in use, the openings at both ends of the frame 310 are aligned with the two pipe bodies 110, so that the water flow can pass through the frame 310 and pass through the internal tilted swing frame. 330, so that the water flow is filtered by the filter screen 331, and at this time the two water outlets 301 are not aligned and staggered with each other. When the filter screen 331 needs to be cleaned, the frame 310 can be driven to rotate by rotating the rotating plate 320, so that the openings at both ends of the frame 310 are blocked by the inner wall of the shell 100, temporarily cutting off the water flow, and then starting the automatic valve 500 to close the automatic valve 500. After the rotating plate 320 continues to rotate, the two ends of the frame 310 are swapped and the two tube bodies 110 are realigned, and the two water outlets 301 are aligned, so that the water flow can backwash the filter screen 331, and the flushing water flow can be discharged from the two water outlets 301, thereby backwashing the filter screen 331 and improving the cleaning efficiency.

[0028] In this embodiment, when the filter 331 needs to be cleaned, the frame 310 can be driven to rotate by rotating the rotating plate 320, so that the openings at both ends of the frame 310 are blocked by the inner wall of the shell 100, temporarily cutting off the water flow. At this time, there is a certain amount of water flow inside the frame 310. By sliding the movable plate 350 back and forth, the movable plate 350 drives the U-shaped rod 340 to slide up and down through the support arm 342, and the U-shaped rod 340 can pull the swing frame 330 to reciprocate inside the frame 310 through the slider 341, so that the filter 331 reciprocates synchronously with the swing frame 330, so that the filter 331 paddles the water flow during the reciprocating rotation, so that the water flow rinses the filter 331, thereby improving the cleaning effect of the filter 331.
