[0023] Furthermore, the sliding structure includes a movable rod 11, a return spring 12, and a sealing gasket 13. The bottom end of the movable rod 11 is fixedly connected to the top end of the fixed seat 2. The return spring 12 is sleeved on the outer wall of the movable rod 11. The sealing gasket 13 is fixedly connected to the outer wall of the top block 3.

[0024] Among them, the top end of the movable rod 11 passes through the outer wall of the top block 3 and is slidably connected. A diversion port is provided on the inner wall of the sewage inlet 6 to guide the sewage to one side of the cross fan blade 7, so that the cross fan blade 7 can rotate continuously in one direction.

[0025] Furthermore, the top end of the movable rod 11 passes through the outer wall of the top block 3 and is slidably connected, the bottom end of the return spring 12 is fixedly connected to the top end of the fixed seat 2 , and the top end of the return spring 12 is fixedly connected to the bottom end of the top block 3 .

[0026] Among them, after the sewage enters the filter cartridge 5, the sliding structure can push the top block 3 to move downward along the movable rod 11 when the flow rate impact force of the sewage is greater than the elastic force of the reset spring 12, and the water flow impacts the small particles of sand and gravel attached to the inner wall of the filter cartridge 5 and enters the storage chamber 1.

[0027] Furthermore, the cleaning structure includes a first bevel gear 14, a second bevel gear 15, a connecting rod 16, a first gear 17, a hollow gear 18, a fixed rod 19, and a fixed shaft 20. The first bevel gear 14 is fixedly connected to the rotating shaft of the cross fan blade 7, the second bevel gear 15 is rotatably connected to the top of the filter chamber 4, and the first bevel gear 14 and the second bevel gear 15 are meshed with each other.

[0028] The bottom end of the connecting rod 16 penetrates the outer wall of the filter chamber 4 and is fixedly connected to the top end of the first gear 17 .

[0029] Furthermore, the top end of the connecting rod 16 is fixedly connected to the bottom end of the second bevel gear 15 , the first gear 17 is fixedly connected to the bottom end of the connecting rod 16 , the hollow gear 18 is fixedly connected to the top end of the scraper 8 , and the first gear 17 and the hollow gear 18 are meshed with each other.

[0030] The bottom end of the sewage inlet 6 is lower than the position of the hollow gear 18 , and the bottom end of the fixed shaft 20 is rotatably connected to the top end of the movable rod 11 .

[0031] Furthermore, the fixing rod 19 is fixedly connected to the inner wall of the scraper 8 , the top end of the fixing shaft 20 is fixedly connected to the fixing rod 19 , the scraper 8 is slidably connected to the outer wall of the filter cartridge 5 , and the filter cartridge 5 is arranged on the periphery of the top block 3 .

[0032] The area of ​​the filter cartridge 5 is larger than that of the top block 3 , and a triangular tip is provided on the inner wall of the scraper 8 and abuts against the outer wall of the filter cartridge 5 , thereby making it easier to scrape the outer wall of the filter cartridge 5 .

[0033] Working principle: First, when the filter is in normal use, the sewage will contact the cross blades 7 before entering the filter chamber 4 from the sewage inlet 6. Under the impact of the sewage, the cross blades 7 will rotate at high speed, thereby driving the coaxial first bevel gear 14 to rotate, the first bevel gear 14 drives the second bevel gear 15 to rotate, the second bevel gear 15 drives the first gear 17 to rotate, the first gear 17 drives the hollow gear 18 to rotate, and the hollow gear 18 drives the scraper 8 to rotate on the outer wall of the filter cylinder 5 and clean it.

[0034] Then, when the debris is collected to a certain extent, the flow rate of sewage can be increased. After the sewage enters the filter cartridge 5, when the impact force of the sewage flow rate is greater than the elastic force of the reset spring 12, the top block 3 can be pushed to move downward along the movable rod 11, and the water flow impacts the small particles of sand and gravel attached to the inner wall of the filter cartridge 5, enters the storage chamber 1 and is finally discharged through the discharge pipe 10. Therefore, not only can the debris left after filtration be flushed into the discharge chamber through the sliding structure through the sewage, but the cross blades can also be driven to rotate by the impact of the sewage, thereby driving the scraper to rotate. While saving power, the surface of the filter element can be cleaned at any time, which greatly improves the filtering effect of the filter element.
