[0021] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0022] As shown in Figures 1-6, a self-cleaning filter includes a filter installation column 10 and a water pipe 11, the filter installation column 10 and the water pipe 11 are arranged perpendicular to each other, and the water pipe 11 is hollow, characterized in that: one side end surface of the filter installation column 10 is provided with an opening, and the bottom of the filter installation column 10 is provided with a secondary arc hole 19, the secondary arc hole 19 is connected to the opening in the filter installation column 10, and the secondary arc hole 19 is located on the edge of one side of the bottom circular surface of the filter installation column 10 perpendicular to the water pipe 11, and a filter assembly and a rotating assembly are arranged in the opening;

[0023] The rotating assembly includes a bottom plate 15 located at the bottom of the opening of the filter mounting column 10 and a hexagonal swivel 12 located on the end surface of the opening side of the filter mounting column 10. A baffle for blocking water flow is fixed between the hexagonal swivel 12 and the bottom plate 15. There is a certain damping between the hexagonal swivel 12 and the filter mounting column 10, so that the hexagonal swivel 12 will not easily rotate.

[0024] The filter assembly includes a filter nut 13 threadedly connected to a hexagonal swivel 12, and a pluggable filter screen 17 is provided on the filter nut 13. The filter screen 17 is connected to the filter nut 13 through a turntable 14. The turntable 14 is rotatably connected to the filter nut 13 to avoid the filter screen 17 from getting stuck when the filter nut 13 is screwed.

[0025] The bottom plate 15 is also provided with a main arc hole 18 passing through, and the baffle is two symmetrically arranged side plates 16, which are symmetrically arranged with the main arc hole 18 as the center, and the side plates 16 are divided into solid plates and strip plates, which can cooperate with the main arc hole 18 and the secondary arc hole 19 to rotate the hexagonal swivel 12 to change the direction of water flow.

[0026] When in use, water flows through the water pipe 11 and will be filtered by the filter assembly when passing through the filter installation column 10. When the filtered impurities gather more on the filter screen 17, it will affect the flow rate of the water flow. At this time, it is necessary to rotate the rotating assembly to drive the filter assembly to rotate synchronously until the main arc hole 18 is connected with the secondary arc hole 19. At this time, the solid plate of the side plate 16 will block the water outlet of the filter installation column 10, and the strip plate is located at the water inlet of the filter installation column 10. At this time, the water will flow between the two filter screens 17 and then be Since the main arc hole 18 is located on the side of the filter 17 close to the water pipe 11, the water flow will impact the filter 17 and then flow out from the main arc hole 18 and the secondary arc hole 19. At this time, the impurities filtered on the filter 17 are washed down and separated from the filter 17 under the impact of the water flow, and then follow the water flow through the main arc hole 18 and the secondary arc hole 19 to the outside. After the cleaning is completed with the impact of the water flow, the rotating component is rotated to reset the filter 17 and filter the water again. The filter 17 can be cleaned without disassembling the filter.

[0027] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
