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 10):
The fan according to  claim 6 , wherein the angle feedback device comprises an infrared photoelectric rotary encoder and an encoder read head, the parameter outputted by the angle feedback device comprises a pulse signal outputted by the encoder read head according to a change of a scale of the infrared photoelectric rotary encoder, and the preset correspondence relationship comprises a rotation angle of the swinging head corresponding to one pulse signal;\n the processor is configured to calculate the current rotation angle of the swinging head according to the parameter outputted by the angle feedback device and the preset correspondence relationship between parameters and angles by acts of: taking a product of the number of the pulse signals outputted by the encoder read head and the rotation angle of the swinging head corresponding to the pulse signal as the current rotation angle of the swinging head.
