Abstract

The invention discloses a control method for the rotation angle of a fan swing head, a device and a fan. The method is applied to the fan adopting a brushless motor. The fan swing head is structurally provided with an angle feedback device. The fan swing head rotates under the drive of the brushless motor. The method comprises the steps that parameters output by the angle feedback device are collected; the parameters output by the angle feedback device change along with the rotation of the fan swing head; and the current rotation angle of the fan swing head is calculated according to the incidence relation of the parameters output by the angle feedback device and the preset parameters and the angle. The rotation of the fan swing head is controlled according to the current rotation angle of the fan swing head and the preset target rotation angle. By the adoption of the control method for the rotation angle of the fan swing head, the device and the fan, the service life of the fan can be prolonged, the rotation angle of the fan swing head can be controlled precisely, and the user experience is improved.

Description

technical field [0001] The present disclosure relates to communication technology, and in particular to a method and a device for controlling the swing angle of a fan, and a fan. Background technique [0002] Fan is a common electrical appliance in people's daily life. It has various types. From the perspective of installation location, it can include ceiling fans, desk fans, floor fans, etc. From the perspective of swing, it can be divided into swingable head fans and non-swingable fans. head fan. Among them, for users with relatively scattered indoor seats, the fan that can swing the head provides a lot of convenience for users to enjoy the cool air. [0003] The current swingable head fan can generally control the rotation angle of the fan swing head at will. There are many ways to control the rotation angle, the most direct is to use a stepper motor to control the rotation angle. However, the life of the stepper motor is generally only a few thousand hours, which is d...
