FAN HEAD SWINGING DEVICE |
摘要 |
A fan head-swinging device includes a speed reducer and a DC motor. The speed reducer consists of plural gears engaging with each other. The DC motor is fixed behind a housing of a fan, having a spindle fixed on with a small gear engaging with one of the plural gears of the speed reducer. So the shaft of that gear may rotate with a very slow speed suitable to the fan head to swing right and left for a proper angle by controlling the DC motor.
