Ceiling fan

摘要

A ceiling fan includes an outer rotor motor having a rotor connected to a rotating disc and a stator connected with an inner tube. An outer tube is fitted around the inner tube, having one end connected with the rotating disc, and a plurality of elastic buffer pieces are positioned between the outer tube and the rotating disc. By so designing, when the rotor is rotated to actuate the rotating disc together with the outer tube to rotate, the elastic buffer pieces can absorb the vibration produced by operation of the outer rotor motor and also correct bias swinging of the outer tube through their elastic deformation to enable the outer tube to be rotated stably.
