[0037] In specific use, the water inlet pipe 21 guides the required stored water resources into the cavity of the water storage chamber 20, and when the water resources enter the cavity of the water inlet pipe 21, they will fall on the top of the side rod 33 and the filter plate 44, and then the water resources will be filtered downward through the round holes opened on the top of the filter plate 44, and then the water resources filtered by the upper filter plate 44 will fall on the top of the lower filter plate 44, and then be filtered again through the wall surface of the lower filter plate 44, and finally be stored at the bottom of the cavity of the water storage chamber 20. When it is required to discharge the water resources in the cavity of the water storage chamber 20, the valve on the wall surface of the drain pipe 22 is opened, and the water resources in the cavity of the water storage chamber 20 will be discharged through the valve on the wall surface of the drain pipe 22. When it is required to clean the wall surface of the filter plate 44, the power of the motor 24 is started, and the motor 24 can drive the upper symmetrical rotating rod 31 to rotate, and the upper rotating rod 31 will drive the corresponding second sliding block 36 and the first sliding block 34 to slide synchronously along the opening of the fixed rail 30 when rotating. When the first sliding block 34, the first fixed shaft 35, the second sliding block 36 and the second fixed shaft 37 slide, the fixed rod 40, the upper arc ring 41, the moving plate 43 and the filter plate 44 will slide synchronously towards the cavity of the cleaning chamber 23. When the second sliding block 36 slides to contact the wall surface of the sensing assembly 25, it stops. When the second sliding block 36 contacts the sensing assembly 25, the upper arc ring 41 will move downward due to gravity and drive the moving plate 43 to be inclined in the cavity of the cleaning chamber 23 with the first fixed shaft 35 as the center. At this time, the water spray 26 will spray water through the nozzles at the bottom thereof to the top of the filter plate 44, so as to spray the impurities on the top of the filter plate 44 into the cavity of the cleaning chamber 23. The sprayed impurities will slide from the gap between the inclined moving plate 43 and one side of the cavity of the cleaning chamber 23 to the bottom of the cavity of the cleaning chamber 23, and then be guided to the rectangular groove at the bottom of the cavity of the cleaning chamber 23 by the right-angled triangular block at the bottom of the cavity of the cleaning chamber 23 and then be discharged. After the top of the upper filter plate 44 is cleaned, the rotating rod 31 will rotate to drive the filter plate 44 to return to the cavity of the water storage chamber 20. The fixed rod 40 will not be horizontal due to the contact with the wall surface of the limiting block 32. After the position of the upper filter plate 44 successfully returns to the cavity of the water storage chamber 20, the sensing assembly 25 will control the lower symmetrical rotating rod 31 to rotate through the motor 24, so as to drive the lower filter plate 44 to enter the cavity of the cleaning chamber 23. When the lower filter plate 44 moves to the most side of the cavity of the cleaning chamber 23, the fixed rod 40 will be flipped downward with the corresponding first fixed shaft 35 as the center. At this time, the second fixed shaft 37 in the opening of the lower clamping block 42 will be separated from it, and then the moving plate 43 will be inclined. Then the bottom of the water spray 26 will be sprayed and cleaned. After the cleaning is completed, the filter plate 44 will be returned to the position right below the upper filter plate 44 through the rotating rod 31.

[0038] In summary, by setting up a filtration structure and using two filter plates 44 for cyclic cleaning, not only can water resources be filtered, but the cleaning of impurities from the filter plates 44 is also maintained, thus giving this solution the advantage of no working vacuum period. Furthermore, the step-by-step filtration of water resources by the two filter plates 44 results in higher filtration accuracy and cleaner water quality. In addition, the right-angled triangular blocks in the cleaning chamber 23, combined with the automatically tilted filter plates 44 during cleaning, ensure that the cleaned impurities can be smoothly discharged from the bottom of the cleaning chamber 23 without accumulating in the cleaning chamber 23 or on the walls of the filter plates 44, thus preventing odors.

[0039] like Figure 2 and Figure 3 As shown, a water sprayer 26 is fixedly connected to the top of the cavity of the cleaning chamber 23. Multiple nozzles are installed at the bottom of the water sprayer 26. The bottom of the water sprayer 26 is inclined towards the motor 24. A right-angled triangular block is fixedly connected to the bottom of the cavity of the cleaning chamber 23. The lowest point of the inclined surface of the right-angled triangular block faces the rectangular groove at the bottom of the cleaning chamber 23. A cleaning rod 27 is fixedly connected to one side wall of the cavity of the cleaning chamber 23. The cleaning rod 27 is a rectangular plate. Brushes are symmetrically installed on the upper and lower walls of the cleaning rod 27. The cleaning rod 27 is located between the symmetrical rectangular grooves on one side of the cavity of the cleaning chamber 23. The brushes on the upper and lower walls of the cleaning rod 27 can contact the bottom of the upper filter plate 44 and the top of the lower filter plate 44.

[0040] In practical use, as the filter plate 44 moves, it can come into contact with the brush on the wall of the cleaning rod 27, and as the filter plate 44 comes into contact with the brush, the wall of the filter plate 44 can be simply washed.

[0041] In summary, by setting the brush on the wall of the cleaning rod 27, the wall of the filter plate 44 can be automatically cleaned as the filter plate 44 moves, thereby reducing the time required to clean the filter plate 44 and improving the efficiency of cleaning the filter plate 44.

[0042] Working principle: The inlet pipe 21 introduces the required water resources into the storage chamber 20. When the water enters the chamber of the inlet pipe 21, it falls onto the top of the side rod 33 and the filter plate 44. Then, the water is filtered downward through the round hole at the top of the filter plate 44. The water filtered by the upper filter plate 44 falls to the top of the lower filter plate 44 and is then filtered again through the wall of the lower filter plate 44. Finally, it is stored at the bottom of the storage chamber 20. When it is necessary to drain the water resources in the storage chamber 20, the valve on the wall of the drain pipe 22 is opened, and the water resources in the storage chamber 20 are discharged through the valve on the wall of the drain pipe 22.

[0043] It can be understood that the utility model is described through some embodiments, and the person skilled in the art knows that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the utility model. In addition, under the guidance of the utility model, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the application belong to the scope protected by the utility model.
