Among them, the outer peripheral wall of annular pipe 2.1 is uniformly fixedly connected with multiple fixed lug plates 2.5 along circumferential direction;Annular pipe 2.1 top surface is fixedly connected with pipe joint 2.4;Multiple straight pipes 2.2 are evenly distributed in annular pipe 2.1 along circumferential direction, and the center position of annular pipe 2.1 is provided with center plate 2.6 fixedly connected with the inner end of straight pipe 2.2. That is, aeration mechanism 2 is in the shape of circular frame structure, and the rigidity and support strength of the whole frame are improved by center plate 2.6.

[0029] The air outlet end of air supply hose 8 is connected with the air inlet end of annular pipe 2.1. That is, the air inlet end of air supply hose 8 is connected to air compressor equipment, and the air outlet end of air supply hose 8 is sleeved on pipe joint 2.4.

[0030] The pool 1 is circular, and the outer edge of the bottom surface of the annular shell 3 is fixedly connected to the top surface of the pool 1.

[0031] The inner tooth ring 4 is rotatably installed at the outer edge position of the inner cavity of the annular shell 3.

[0032] Multiple transmission members 5 respectively include driven gear 5.1 engaged with inner tooth ring 4 and threaded sleeve 5.2 fixedly sleeved at the axial position of driven gear 5.1 and rotatably sleeved at the top and bottom plates of annular shell 3.
