ABSTRACT:
An electricity-free rotary wind blowing apparatus including a wind guiding device, a spreading device and a supporting device. The supporting device has a central seat portion disposed with an inner bearing. The spreading device is rotatable secured to the bearing. The wind guiding device has a central shaft seat and a peripheral rim. Multiple radial inclined wind guiding vanes are disposed between the shaft seat and the peripheral rim. The air flow blows from the wind exit of a wind pipe of an air-conditioning system onto the vanes and is guided thereby so as to exert a rotating force onto the spreading device, whereby the spreading device itself is rotatably driven by the air flow without using electricity to evenly spread the air flow.
