Abstract: The present invention provides air fans with enhanced oscillating mechanism. In one aspect of this invention, the air fan comprises main propeller (19), a main motor (24) operably connected to the main propeller (19), driving the main propeller (19) to rotate to generate air stream, and a wind guide device composed of a wind guard plate (35) and a wind reject plate (21) and surrounding the main propeller (19). An auxiliary motor (53) operably connected to the wind guide device via a rotation-oscillation shifting device, for driving the wind guide device to oscillate to change the wind direction. In a further aspect of this invention, only the motor for the oscillating mechanism is in motion to drive the relatively lighter wind channel while the enclosure and motor for the wind wheel remain static during operation. The air fans feature less safety hazard, a prolonged service life, a lower noise and easier operation.

Abstract: The present utility model provides an air fan, comprising: a main propeller (19); a main motor (24) operably connected to the main propeller (19), driving the main propeller (19) to rotate to generate air stream; characterized in that the air fan further comprises a wind guide device composed of a wind guard plate (35) and a wind reject plate (21) and surrounding the main propeller (19), a gap is provided between the wind guard plate (35) and the wind reject plate (21) for facilitating flowing out of air; an auxiliary motor (53) operably connected to the wind guide device via a rotation-oscillation shifting device, for driving the wind guide device to oscillate to change the wind direction.
