Abstract
An electric fan includes a fan base (), a bearing () and a rotor assembly (). The fan base forms a central tube () receiving the bearing therein. The rotor assembly includes a fan hub (), and a pivot axle () joined to the fan hub. The pivot axle pivotably extends into the bearing. A first and second locking rings () are received in the central tube. Each of the first and second locking rings defines a central bore () therein. The pivot axle is engaged in the central bores of the first and second locking rings. The first locking ring is located at a top of the bearing and the second locking ring is located at a bottom of the bearing to prevent the rotor assembly from escaping from the bearing when the fan is operated.
