A first sprocket 27 is coaxially arranged on the second rotating shaft 26. Two rotating rods 28 and two shifting posts 29 are symmetrically arranged on the other end of the second rotating shaft 26. An arc piece 30 is arranged on the end of the rotating rod 28 away from the second rotating shaft 26. The arc piece 30 passes through the opening 24, and the shifting post 29 slides in the slideway 23.

[0030] The bottom end of the sleeve 20 is connected to the arc chute body 31, and the two ends of the arc chute body 31 are respectively connected to the two ends of the linear chute body 32. A second sprocket 33 is arranged in the arc chute body 31, and the third rotating shaft 34 is coaxially connected to the second sprocket 33. The first sprocket 27 and the second sprocket 33 are connected through a chain 35. One end of the third rotating shaft 34 is rotatably connected to the inner wall of the transmission box 16, and the other end of the third rotating shaft 34 is connected to one end of the crank 36, and the other end of the crank 36 is connected to one end of the sliding column 37, and the other end of the sliding column 37 extends into the linear chute body 32. The two ends of the rotating column 17 pass through two fixed blocks 38 respectively, and the rotating column 17 is rotatably connected to the fixed blocks 38, and the fixed blocks 38 are connected to the inner wall of the transmission box 16, and the fixed blocks 38 play a supporting role for the rotating column 17.

[0031] The gas delivery device includes: a cylinder 39, a vertical cylinder 39 is arranged on the right side of the arc chute body 31, the cylinder 39 is connected to the inner wall of the transmission box 16, a gas tank 40 is arranged above the cylinder 39, one end of the air inlet pipe 41 is connected to the gas tank 40, the other end of the air inlet pipe 41 is connected to the top of the cylinder 39, an air inlet check valve 42 is arranged on the air inlet pipe 41, one end of the air outlet hose 43 is connected to the top of the cylinder 39, an air outlet check valve 44 is arranged on the air outlet hose 43, the other end of the air outlet hose 43 is connected to the sleeve 20, a reciprocating piston 45 is arranged in the cylinder 39, one end of the U-shaped connecting rod 46 is connected to the piston 45, the other end of the U-shaped connecting rod 46 is connected to the linear chute body 32, the U-shaped connecting rod 46 passes through the support block 47, and is slidably connected to the support block 47, and the support block 47 is connected to the inner wall of the transmission box 16.

[0032] The working principle and beneficial technical effects of the above technical solution are as follows: the motor 25 is started to drive the second rotating shaft 26 to rotate, and the second rotating shaft 26 drives the first sprocket 27, the rotating rod 28, the shifting post 29 and the arc piece 30 to rotate. When the arc piece 30 passes through the opening 24 on the circular plate 22, the rotating drum 21 remains stationary. When the two shifting posts 29 slide in the two slideways 23 respectively, the rotating drum 21 realizes the forward and reverse alternating rotation, and the rotating drum 21 accordingly drives the first rotating shaft 18 and the fixed cleaning brush 9 to intermittently rotate. The first sprocket 27 rotates alternately in forward and reverse directions. At the same time, through the transmission of the chain 35, the first sprocket 27 drives the second sprocket 33 to rotate, and the second sprocket 33 drives the third shaft 34, the crank 36 and the slide post 37 to rotate. When the slide post 37 slides in the linear slide groove body 32, the linear slide groove body 32 reciprocates up and down. When the slide post 37 moves in the arc slide groove body 31, the linear slide groove body 32 remains stationary, which correspondingly drives the sleeve 20, the first shaft 18 and the fixed cleaning brush 9 to reciprocate up and down, and The top stops, and also drives the piston 45 to move up and down reciprocatingly in the cylinder 39, and stops at the top. When the piston 45 moves downward, the cylinder 39 inhales gas from the gas tank 40. When the piston 45 moves upward, the cylinder 39 discharges gas and delivers gas to the recoil hole 10 through the air outlet hose 43, the sleeve 20, the first rotating shaft 18 and the rotating tube 8. Through the composite superposition of movements, the rotating tube 8 and the cleaning brush 9 first move upward to the top, and then rotate to clean the water hole 6, and spray a large number of impact bubbles to recoil the filter material. After that, the rotating tube 8 and the cleaning brush 9 move downward to the bottom, then move upward to the top, rotate in the opposite direction to clean the water hole 6, and spray a large number of impact bubbles to recoil the filter material, and finally move downward to the bottom again, and continuously circulate to clean the water port and the filter material. Since the recoil hole 10 will only spray a large number of bubbles when it is close to the adsorption filter layer 5, and rotate and spray, it can generate bubbles with a large range and strong impact force, thereby improving the cleaning efficiency.
