The sleeve 6 is integrally cast on the connecting shaft 4. The fan blades 7 and the sleeve 6 are transitioned by an arc. The plurality of fan blades 7 are all bent and bent toward the direction of the ring gear 1 to achieve a better wind gathering effect. A wind hood 8 is connected to the connecting shaft 4, and the wind hood 8 is a bowl-shaped structure. A plurality of air outlets 9 are opened at the end of the wind hood 8.
[0014] Preferably, the gear ring 1 is fixed and fits with the wind shield 8 ; the wind shield 8 has a gasket that fits with the gear ring 1 ; and a plurality of bearing parts are provided between the wind shield 8 and the connecting shaft 4 .
[0015] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0016] Although the present invention uses more terms such as ring gear 1, sun gear 2, planetary gear, connecting shaft 4, transmission shaft 5, sleeve 6, fan blade 7, fan cover 8, and air outlet 9, it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
