[0026] In some examples, the cleaning assemblies 7 comprise connecting grooves 71, mounting boxes 72, electric push rods 73, push plates 74 and brushes 75, the connecting grooves 71 penetrate the inner walls of both sides of the filter tank 1 and the bottoms are at the same horizontal plane with the filter screen 5, the mounting boxes 72 are fixedly connected to one side of the filter tank 1 and communicate with the connecting grooves 71, the electric push rods 73 are mounted in the mounting boxes 72, the push plates 74 are fixedly connected to the electric push rods 73, the brushes 75 are fixedly connected to the bottoms of the push plates 74, the whole of the push plates 74 and the brushes 75 is adapted to the size of the filter screen 5 and the connecting grooves 71, when the filter screen 5 is blocked by a large amount of garbage accumulated on the surface, the electric push rods 73 are started to drive the push plates 74 and the brushes 75 to move horizontally on the top of the filter screen 5, in this process, the garbage in the aperture of the filter screen 5 is brushed out by the brushes 75, and the garbage brushed out by the brushes 75 and the garbage accumulated on the top of the filter screen 5 is pushed away by the push plates 74.

[0027] In some examples, the cleaning assemblies 7 further comprise collecting boxes 76, baffles 77 and collecting boxes 78, the collecting boxes 76 are fixedly connected to the other side of the filter tank 1 and communicate with the connecting grooves 71, the baffles 77 are semicylindrical at the top and the bottom, the baffles 77 are adapted to the size of the connecting grooves 71 and are rotatably connected to the inner walls of both sides of the connecting grooves 71 at both ends of the top, the collecting boxes 78 are movably arranged in the collecting boxes 76, when the garbage pushed away by the push plates 74 contacts with the baffles 77, the bottom of the baffle 77 is lifted up by the garbage because the top of the baffle 77 is rotatably connected to the connecting grooves 71, at this time, the garbage can fall into the collecting boxes 78 in the collecting boxes 76 through the connecting grooves 71 for collection, when the collecting boxes 78 are full of garbage, the collecting boxes 78 can be taken out by pulling them to the outside and the garbage in the collecting boxes 78 can be disposed.

[0028] In some examples, the water distribution assembly 8 comprises water inlet pipes 81, rotating grooves 82, rotating rings 83 and water distribution pipes 84, the water inlet pipes 81 are adapted to the size of the water inlet 3, the water distribution pipes 84 are arranged in two groups and fixedly connected to the bottoms of the water inlet pipes 81, the rotating grooves 82 are arranged in the inner walls of the middle of the water inlet 3, the rotating rings 83 are fixedly connected to the outer periphery of the top of the water inlet pipes 81 and rotatably connected to the rotating grooves 82, the water inlet pipes 81 can be driven to rotate by rotating the rotating rings 83 along the rotating grooves 82, the water distribution pipes 84 can rotate synchronously with the water inlet pipes 81 because the water distribution pipes 84 are fixedly connected to the bottoms of the water inlet pipes 81, so that the sewage can be uniformly sprinkled into the filter tank 1.

[0029] In some examples, the water distribution assembly 8 further comprises a first gear 85, a motor 86, a through slot 87, a drive shaft 88 and a second gear 89, the first gear 85 is fixedly connected to the outer periphery of the bottom of the water inlet pipe 81, the motor 86 is installed on the top of the pool cover 2, the through slot 87 penetrates through the pool cover 2, the drive shaft 88 is installed on the motor 86 and movably connected to the through slot 87, the second gear 89 is fixedly connected to the bottom of the drive shaft 88 and engaged with the first gear 85, starting the motor 86 to drive the second gear 89 to rotate synchronously through the drive shaft 88, since the second gear 89 is engaged with the first gear 85, the first gear 85 will drive the water inlet pipe 81 to rotate synchronously with the drive shaft 88 of the motor 86.

[0030] In a specific application scenario, first connect the sewage pipe with the water inlet 3, then start the motor 86 to drive the second gear 89 to rotate synchronously through the drive shaft 88, since the second gear 89 is engaged with the first gear 85, the first gear 85 will drive the water inlet pipe 81 to rotate synchronously with the drive shaft 88 of the motor 86, and since the water distribution pipe 84 is fixedly connected to the bottom of the water inlet pipe 81, the water distribution pipe 84 will rotate synchronously with the water inlet pipe 81, thereby uniformly spreading the sewage into the filter tank 1, in this process, the rotating ring 83 will rotate synchronously with the water inlet pipe 81 along the rotating groove 82 and guide the water inlet pipe 81, avoiding the position deviation of the water inlet pipe 81 affecting the water inlet effect, the sewage entering the filter tank 1 will first contact the filter screen 5, the filter screen 5 will filter the solid waste in the sewage, the filtered sewage will contact the filter layer 6 and react with the heavy metals in the sewage, and the treated sewage will finally be discharged from the water outlet 4, when the filter screen 5 surface accumulates more garbage or the aperture is blocked, start the electric push rod 73 to drive the push plate 74 and the brush 75 to move horizontally on the top of the filter screen 5, in this process, the brush 75 will brush out the garbage in the aperture of the filter screen 5, and the push plate 74 will push away the garbage brushed out by the brush 75 and the garbage accumulated on the top of the filter screen 5, when the garbage pushed away by the push plate 74 contacts the baffle 77, since the baffle 77 is rotatably connected to the connecting groove 71 at the top, the bottom of the baffle 77 will be lifted by the garbage, at this time the garbage can fall into the collecting box 78 of the collecting box 76 through the connecting groove 71 for collection, when the collecting box 78 inside collects more garbage, pulling the collecting box 78 outward can take it out and treat the garbage in it.

[0031] By adopting the above technical scheme, not only can the filter screen be cleaned when it is blocked, effectively avoiding the influence of the accumulation of too much garbage on the filtering efficiency, but also the sewage can be uniformly spread into the filter tank, so that the sewage can uniformly contact the filter screen and the filter layer, thereby improving the filtering efficiency.

[0032] Finally, it should be noted that: apparently, the above examples are merely for the purpose of clearly illustrating the utility model, and not limited to the implementation. For ordinary skilled in the art, on the basis of the above description can also be made other different forms of changes or variations. Here do not need to and can not all the implementation to be exhausted. The obvious changes or variations derived from still within the scope of the utility model.
