FAN WHEEL STRUCTURE

摘要

A fan wheel structure includes a ring member and a rotor. The ring member has two opposite open ends and an inner space defined between and communicable with the two open ends. A blade seat having a plurality of blades formed therearound is insert-molded on an outer side of the ring member. The rotor includes a hub fitted in the inner space of the ring member to associate with the ring member and the blade seat, and a rotary shaft having a coupling end inserted into the hub. The rotor can be fitted in the inner space of the ring member from either of the two open ends thereof for the completed fan wheel structure to have either a clockwise or a counterclockwise blade rotating direction. Therefore, only one mold, and accordingly an effectively reduced cost, is needed for manufacturing the fan wheel structures of different rotating directions.
