[0027] In this embodiment, in order to facilitate a clearer description of the positional relationship of each component, the direction from the top to the bottom of the impurity removal tank 200 is set as a preset direction.

[0028] In this embodiment, the inner tank 220 can move in a preset direction and can be connected or separated from the outer tank 230. Specifically, a guide groove 221 is recessed at the bottom of the inner tank 220, and the guide groove 221 extends toward the top of the inner tank 220. At least one connecting hole 222 is opened in the groove wall of the guide groove 221.

[0029] The guide assembly includes an elastic member 400 and a partition column 500. In this embodiment, the length direction of the partition column 500 is parallel to the axis direction of the inner tank 220. The elastic member 400 includes a plurality of springs arranged at equal intervals, and the plurality of springs are arranged around the partition column 500.

[0030] The elastic member 400 is connected to the inner bottom wall of the outer tank 230 and the outer bottom wall of the inner tank 220, respectively. One end of the partition column 500 is connected to the inner bottom wall of the outer tank 230, and the other end extends toward the guide groove 221, and the guide groove 221 is covered by the partition column 500. At least one connecting groove 510 is recessed on the side wall of the partition column 500, and the connecting groove 510 extends along the length direction of the partition column 500. In this embodiment, the connecting hole 222 can be connected or separated with the connecting groove 510 to connect or separate the interior of the inner tank 220 from the accommodating space 240.
