[0025] In order to prevent the water from flowing back, a one-way valve is fixedly connected in the second delivery pipe 12 .

[0026] In order to drive the slide plate 10 to slide, a driving component for driving the stirring component to move is provided in the bellows 4 .

[0027] Specifically, the driving assembly includes a rotating rod 15 rotatably connected to the bellows 4 and a plurality of blades 16 fixedly connected to the outside of the rotating rod 15.
