The accumulated water mixed with impurities enters the water collecting tank 100 and is intercepted and filtered by the cylindrical filter 121. The intercepted clean water is extracted from the water pump 127 and the water supply pipe 2 211, and finally discharged along the water supply pipe 1 210.

[0034] Example 1

[0035] like Figure 1-2 and Figure 5As shown, in this embodiment, a door hole is provided on the end side of the water collecting box 100 away from the push rod 312, and the position where the door hole is opened in the water collecting box 100 is connected to the box door 113 by a hinge rotation, and the outer wall of the box door 113 is fixedly connected to the handle 114, and the two opposite inner walls of the water collecting box 100 are provided with a slide groove 115 near the door hole.

[0039] During specific implementation, the accumulated water extracted from the suction pipe 110 may also contain lumps of impurities and small stones. By providing an interception plate 140 between the holes of the cleaning component 130 and the suction pipe 110, the interception plate 140 can perform preliminary filtration on the extracted accumulated water to intercept large impurities and prevent the hard stones from excessively wearing the cylindrical filter screen 121. When the extraction is completed, after opening the box door 113, the pull ring 142 can be pulled to move the slider 143 along the slide groove 115, so that the interception plate 140 can push out the large impurities located in this area in the water collecting tank 100.
