The outer wall of the inner cylinder 1 is provided with a plurality of groups of first through holes 213. The outer surface of the outer sleeve 214 is provided with a plurality of groups of second through holes 217.

[0027] The suction assembly 22 is disposed inside the inner cylinder 1 and is used to suck water entering the inner cylinder 1 .

[0028] In this embodiment, a parallel block 215 is fixed to the upper outer wall of the outer sleeve 214, and a rotating clamping rod 216 is rotatably installed on the inner side of the parallel block 215. The rotating clamping rod 216 can be fitted into the inner side of the U-shaped clamping block 212. By pulling the rotating clamping rod 216 out of the U-shaped clamping block 212, the outer sleeve 214 can be rotated, and the position can be adjusted and then re-engaged and fixed.

[0029] In this embodiment, the plurality of groups of first through holes 213 are aligned vertically, and the second through holes 217 are staggered along the upper circumference of the outer surface of the outer sleeve 214. The number of U-shaped blocks 212, first through holes 213, and second through holes 217 is the same.
