Abstract
A multi-functional electric fan comprises a U-shaped brace pivotably mounted to motor, a support for supporting the brace, an arcuate guide mechanism hinged to the support, a transmission mechanism having a plurality of gears and an arm secured to a pin through an opening of the guide mechanism, a transverse post, and a vertical post. Thus fan can pivot transversely and longitudinally by the cooperation of posts, gears, pin, and opening at the same time to reciprocally induce air movement in a transverse, longitudinal, wavy, or fixed direction.
