ABSTRACT:
A motor-operated fan includes a housing, a motor secured in the housing, and an impeller rotatably mounted on the housing and rotated by the motor. Thus, the impeller has a plurality of blades and a plurality of auxiliary blades to produce a larger air flow when the impeller is rotated so as to push a ball located above the air cushion table, so that the ball is moved above the air cushion table in an irregular manner at a higher speed, thereby providing an amusement playing effect for players.
