However, since the impurities have a certain degree of adhesion, some impurities will still adhere to the surface of the filter screen. When the thiourea synthetic liquid falling from the liquid inlet pipe passes through the first fan blade, the impact force of the thiourea synthetic liquid can rotate the first fan blade. The first fan blade can drive the first cleaning component to rotate on the top surface of the filter screen through the rotating shaft, and the impurities attached to the surface of the filter screen can be separated from the filter screen.

When the rotating body is separated from the trigger plate, the first return spring can pull the piston rod and the piston body to move upward. When the filter screen is blocked, the inner cavity groove is in a negative pressure state, which can suck out impurities in the filter holes of the filter screen upward, and can automatically clean the impurities in the filter holes of the filter screen to avoid impurity accumulation.

When the rotating body is separated from the fixed body, the second reset spring can drive the rotating plate to reset. Through the back and forth sliding of the rotating plate in the arc-shaped groove, the rotating plate can drive the impurities attached to the bristles to be shaken off, and the impurities attached to the bristles can be automatically cleaned.

[0025] The thiourea synthetic liquid self-cleaning filter described in the present invention can seal the through hole when the switch plate slides downward to separate the filter tank from the cylinder when it is necessary to remove impurities in the cylinder. At this time, the liquid and impurities in the cylinder are discharged together through the discharge port arranged on the bottom surface of the cylinder. In order to prevent the impurities from sinking to the bottom of the cylinder and being unable to be completely removed, when the liquid level drops, the floating block can drive the moving block to move up and down in the slide groove. At the same time, the floating block can drive the stirring rod to move, and the stirring rod can stir the impurities and liquid to prevent the impurities from sinking to the bottom, so that the impurities in the liquid are discharged more thoroughly.

[0051] Specifically, when it is necessary to remove the impurities in the cylinder 41, the switch plate 421 can seal the through hole 13 when sliding downward, and separate the filter tank 1 from the cylinder 41. At this time, the liquid and impurities in the cylinder 41 are discharged together through the drainage port set on the bottom surface of the cylinder 41. In order to prevent the impurities from sinking to the bottom of the cylinder 41 and being unable to be completely removed, when the liquid level drops, the floating block 433 can drive the moving block 432 to move up and down in the slide 431. At the same time, the floating block 433 can drive the stirring rod 434 to move. The stirring rod 434 can stir the impurities and liquid to prevent the impurities from sinking to the bottom, so that the impurities in the liquid are discharged more thoroughly.

[0052] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
