Abstract:
A method and a device are provided for controlling a rotation angle of a swinging head of a fan. The method may be applied in a fan adopting a brushless motor. An angle feedback device is arranged on the swinging head, and the swinging head is driven by the brushless motor to rotate. The device may acquire a parameter outputted by the angle feedback device, where the parameter varies with rotation of the swinging head. The device may calculate a current rotation angle of the swinging head according to the parameter outputted by the angle feedback device and a preset correspondence relationship between parameters and angles. The device may control the swinging head to rotate according to the current rotation angle of the swinging head and a preset target rotation angle.

Claim (Index 11):
A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of a fan, causes the fan to perform a method for controlling a rotation angle of a swinging head of a fan, the method comprising:\n acquiring, by the fan comprising an angle feedback device and a brushless motor, a parameter outputted by the angle feedback device, wherein the parameter outputted by the angle feedback device varies with rotation of the swinging head; calculating a current rotation angle of the swinging head according to the parameter outputted by the angle feedback device and a preset correspondence relationship between parameters and angles; and controlling the swinging head to rotate according to the current rotation angle of the swinging head and a preset target rotation angle by using the brushless motor.
