The two water sources are controlled by the automatic water inlet control valve 1, and no separate isolation is provided.

[0022] Referring to Figure 2 、 Figure 3 The cyclone material flushing device 2 is in a hollow shape of a large upper and small lower circular table, and has an open structure. The cavity between the outer wall 2-1 of the cyclone and the inner wall 2-3 of the cyclone is a water distribution chamber 2-2 of the cyclone. The side wall of the outer wall 2-1 of the cyclone is provided with a cyclone water inlet interface 2-4, which is connected with the automatic water inlet control valve 1 through a pipeline. The upper end of the inner wall 2-3 of the cyclone is provided with cyclone water distribution holes 2-5 which are uniformly distributed around the same plane.
