The rotating shaft 2 is an inner and outer hollow sleeve structure with a closed lower end. The inner hollow tube 21 of the rotating shaft 2 is fixedly sleeved inside the outer hollow tube 22 and the inner and outer hollow tubes are coaxially arranged. The interiors of the plurality of fan blades 3 are all blades of a double-layer sealed cavity structure. The lower ends of the inner hollow tube 21 and the outer hollow tube 22 of the rotating shaft 2 are both connected to the sealed cavity of the fan blades 3. The upper part of the rotating shaft 2 is movably sleeved with an air supply ring 4, and the air supply ring 4 is fixed to the motor 1 through a plurality of connecting pieces 5.
