Abstract
Disclosed is a swing head control mechanism for a ventilator, which comprises a ventilator main electromotor and a synchronous motor. The output shaft of the synchronous motor is connected with a drive gear wheel which is meshed with a driven gear wheel. A swing head central shaft is arranged at the side face of the ventilator main electromotor; a plane bearing is hitched at the tail of the swing head central shaft; a ball bearing is hitched at the head of the swing head central shaft; a swing head support piece is hitched at the outside of the swing head central shaft; the front end of the swing head central shaft can be rotarily connected with the front end of the swing head support piece; and the driven gear wheel is connected with the back end of a swing head guy rod whose front end is connected with the swing head support piece. The swing head control mechanism can conveniently control the swing head of the ventilator. The synchronous motor drives a retarding mechanism so as to drive the head of the ventilator to swing, thus increasing the torque force of the head of the ventilator and making the head of the ventilator swing steadily. Meanwhile, the ball bearing bears the torque force when the head swings and the plane bearing bears the weight of the swing head of the ventilator, thereby, the swing head is durable.
