发明名称 Fan hub with a rocket shaped end
摘要 The present invention relates to a fan hub with a rocket shaped end. The fan hub comprises a hub body with a depressed ditch rounding at a proper position and a guiding section extended from the depressed ditch, and a plurality of fan blades on the outer surface of the hub body. The guiding section gradually narrows to an end and the tip at the end is in a curved shape. Accordingly, when the fan blades rotate, undesirable noise and working current can be reduced; and, simultaneously, the present invention can effectively guide the air flow, decrease the wastage of power, and improve the working efficiency of the fan.
