[0025] Through the connecting pipe 74, the connecting pipe 74 can convey water flow into the interior of the storage box 1 through the conveying pipe 75.

[0026] Wherein, a water inlet and outlet 711 is provided on the outer wall of the outer shell 710, and a rotating shaft 79 penetrates and is rotatably connected to the top end inside the outer shell 710.

[0027] Through the rotating shaft 79, the rotation of the rotating shaft 79 can drive the turntable 77 to rotate, and further drive the water spray nozzle 78 to rotate.

[0028] Wherein, one end of the outer wall of the rotating shaft 79 located inside the outer shell 710 is fixedly connected with a baffle 712, and the bottom end of the rotating shaft 79 is fixedly connected with the top end of the turntable 77.

[0029] Through the baffle 712, the baffle 712 located inside the outer shell 710 is squeezed by the water flow and further drives the rotating shaft 79 to rotate.
