[0028] Cleaning mechanism: two groups of symmetrical limit strips 14 are provided on the inner wall of the tank body 1, and a limit groove 91 is provided on the outer wall of the lifting plate 9. The limit groove 91 cooperates with the limit strip 14 to limit the lifting plate 9, and a plurality of groups of mounting holes 92 are provided on the lifting plate 9. One group of mounting holes 92 corresponds to one group of filter elements 7, and a group of annular cleaning members 10 are installed in each group of mounting holes 92.
