[0028] Further, Figure 2 , Figure 3 and Figure 5As shown: A water storage assembly 3 is provided at the bottom of the outer casing 1. The water storage assembly 3 includes a sewage tank 31. A support plate 37 is fixedly connected to the top of the sewage tank 31. A water pipe 32 is provided on the side of the support plate 37. A collar 36 is slidably connected to the bottom of the water pipe 32. A baffle 33 is fixedly connected to the side of the collar 36. A spring piece 34 is fixedly connected to one end of the baffle 33. A limit block 35 is fixedly connected to one end of the spring piece 34. A handle is provided at one end of the baffle 33. By setting up the sewage tank 31, sewage generated during flushing can be collected. When the sewage tank 31 needs to be replaced, the handle is pulled outward from the sewage tank 31, which causes the collar 36 and the baffle 33 to move outward. This achieves the effect of isolating one end of the water pipe 32 through the baffle 33, preventing residual sewage in the inner cavity of the water pipe 32 from leaking during replacement. The movement trajectory of the collar 36 is limited by the cooperation of the spring piece 34 and the limit block 35.

[0029] When the sewage tank 31 is reset after cleaning, it is inevitable that the connection between the collar 36 and the water pipe 32 will be misaligned, leading to sewage leakage. Figure 5 As shown: In this scheme, the side of the support plate 37 is provided with a sliding groove 38, one end of the limiting block 35 extends into the inner cavity of the sliding groove 38, and one end of the limiting block 35 is slidably connected to the inner cavity of the sliding groove 38. One end of the limiting block 35 is provided with a certain curvature, and the inner cavity of the sliding groove 38 is provided with a groove that matches one end of the limiting block 35. When resetting, the collar 36 is pushed, thereby moving the spring 34 and the limiting block 35 toward the middle of the sewage tank 31. When the limiting block 35 moves to a certain position, the spring 34 is compressed, thereby causing the limiting block 35 to engage with the inner cavity of the sliding groove 38, thereby achieving the effect of positioning the collar 36 and preventing the position from shifting during resetting.

[0030] Working principle:

[0031] like Figures 1-5 As shown:

[0032] In use: when the filter piece 11 needs to be cleaned, the push rod is started, the output end of the push rod moves forward, so that the connecting rod 22 can be driven forward by the sleeve 24, when the connecting rod 22 moves to a certain position, the second fixed block 29 enters the inner cavity of the groove 28, at this time, the output end of the push rod continues to move, and through the cooperation of the first fixed block 25 and the limiting groove 26, one end of the cleaning rod 27 can be turned counterclockwise along the inner cavity of the guide groove 13, thereby achieving the effect of cleaning one side of the filter piece 11. Similarly, when the push rod moves backward, through the cooperation of the limiting groove 26 and the first fixed block 25, the connecting rod 22 can be driven to move backward, when the connecting rod 22 moves to a certain position, the output end of the push rod continues to move, so that the cleaning rod 27 can be turned clockwise, thereby achieving the effect of cleaning the other side of the filter piece 11 by the cleaning rod 27. While the cleaning rod 27 is cleaning, external water supply is provided, so that the spray device arranged on the side of the filter piece 11 can wash the filter piece 11, further improving the cleanliness of the filter piece 11. When the sewage tank 31 needs to be replaced, first pull the handle outward of the sewage tank 31, so that the sleeve ring 36 and the baffle 33 can move outward, thereby achieving the effect of cutting off one end of the water pipe 32 by the baffle 33. When resetting, push the sleeve ring 36, so that the spring piece 34 and the limiting block 35 can move to the middle of the sewage tank 31, when the limiting block 35 moves to a certain position, the spring piece 34 is compressed, so that the limiting block 35 can be clamped with the inner cavity of the sliding groove 38.

[0033] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application still belong to the protection scope of the technical scheme of the present application.
