[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figures 1-7 As shown, in this embodiment, a novel anti-clogging filter valve includes a vertical filter cylinder 1. The lower part of the outer wall of the filter cylinder 1 is connected to an inlet pipe 2, and the upper part is connected to an outlet pipe 3. Water flows into the filter cylinder 1 through the inlet pipe 2 for filtration and flows out through the outlet pipe 3. A backwash pipe 4 is connected to the top of the filter cylinder 1 via the inlet pipe 2, allowing backwashing of the filter cylinder 1. The filter cylinder 1 includes a first filtration mechanism 11 and a second filtration mechanism 12. These two filtration mechanisms alleviate the problem of concentrated clogging by impurities. The first filter mechanism 11 is a cylindrical structure with an open top and filter holes on its outer wall. It is coaxially located at the bottom of the filter cylinder 1. The second filter mechanism 12 is a circular disc-shaped structure with filter holes running through its center. The second filter mechanism 12 is located above the first filter mechanism 11 and is coaxially fixed to the inner wall of the filter cylinder 1. A backwash outlet 13 is also provided at the bottom of the outer circumference of the filter cylinder 1. A sealing cap 131 is threaded to the outer end of the backwash outlet 13. A water outlet switch 31 is installed on the water outlet pipe 3, and a backwash pipe switch 41 is installed on the backwash pipe 4. The water flow direction is adjusted by controlling the water outlet switch 31 and the backwash pipe switch 41.

[0027] Specifically, the diameter of the filter holes in the first filter mechanism 11 is larger than the diameter of the filter holes in the second filter mechanism 12. This prevents larger impurities from being blocked outside the first filter mechanism 11, while smaller impurities are blocked below the second filter mechanism 12.

[0028] Specifically, a bottom cover 14 is bolted to the bottom of the filter cartridge 1. The first filter mechanism 11 and the second filter mechanism 12 can be disassembled and assembled by removing the bottom cover 14.

[0029] Furthermore, a motor 15 is bolted to the center of the bottom surface of the bottom cover 14, and the top output end of the motor 15 is fixed to the center of the bottom surface of the first filter mechanism 11 via a connecting shaft 151. The first filter mechanism 11 is rotated by the motor 15, so that impurities on the outside can be easily discharged from the backwash outlet.

[0030] Specifically, a central ring 16 is fixed to the middle of the inner wall of the filter cylinder 1, and a right-angle groove 161 is formed below the central ring 16. The second filter mechanism 12 is installed on the central ring 16. The second filter mechanism 12 includes a metal ring 121, a metal mesh 122, and a pressure ring 123. The metal mesh 122 is fixed to the middle of the metal ring 121. The metal ring 121 is located in the right-angle groove 161, and its bottom is supported by the pressure ring 123. The pressure ring 123 is threadedly connected to the bottom of the right-angle groove 161. This facilitates the assembly and disassembly of the second filter mechanism 12.

[0031] Specifically, the backwash pipe 4 is equipped with connecting screw sleeves 42 at both ends, and the two connecting screw sleeves 42 are respectively threaded to the water inlet pipe 2 and the top of the filter cylinder 1, which facilitates the disassembly and assembly of the backwash pipe 4.

[0032] The inlet pipe 2 is welded with an inlet pipe flange 21 at its outer end, and the outlet pipe 3 is welded with an outlet pipe flange 32 at its outer end, so that the inlet pipe 2 and the outlet pipe 3 can be easily disassembled and assembled with water pipes.

[0033] The working principle of this utility model is: when the water flows normally, such as Figure 6 As shown, the water outlet pipe switch 31 is turned on and the backwash pipe switch 41 is turned off. Water flows from the inlet pipe 2 to the filter cylinder 1 from bottom to top and flows out from the outlet pipe 3. During this period, the filter holes of the first filter mechanism 11 can block larger impurities on the outside, and the second filter mechanism 12 can block smaller impurities below, thus filtering and preventing impurities from accumulating and clogging.

[0034] When backwashing filter cartridge 1, if Figure 7As shown, the outlet pipe switch 31 is closed, the backwash pipe switch 41 is open, the motor 15 is started, and the sealing cap 131 of the backwash outlet 13 is unscrewed. Water flows into the filter cylinder 1 from both the inlet pipe 2 and the backwash pipe 4. The water entering the filter cylinder 1 through the inlet pipe 2 washes away the impurities accumulated on the outer wall of the first filter mechanism 11. Combined with the rotation of the first filter mechanism 11, it can wash it evenly and flush out the impurities outside the first filter mechanism 11 from the backwash outlet 13. The water flow from the backwash pipe 4 flows into the filter cylinder 1 from top to bottom, washing away the impurities adhering to the bottom of the second filter mechanism 12, causing the impurities to detach from the metal mesh 122, pass through the first filter mechanism 11, and flow out from the backwash outlet 13. This allows the valves to clean impurities and wash the first and second filter mechanisms 11 without disassembly.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
