Abstract

Provided are a method for adjusting the oscillation angle of the fan and a fan. The method includes the following steps: controlling the air outlet assembly to oscillate between a first limit position and a second limit position, and acquiring a signal emitted by the fan in real time; determining that the air outlet assembly oscillates between the first limit position and an intermediate position when a first signal is acquired; determining that the air outlet assembly oscillates between the intermediate position and the second limit position when a second signal is acquired; and determining that the air outlet assembly is at the intermediate position when a transition between the first signal and the second signal is acquired.

A method for adjusting an oscillation angle of a fan, wherein the fan comprises an air outlet assembly, the air outlet assembly is configured to oscillate to a first limit position, an intermediate position, and a second limit position, wherein the intermediate position is located between the first limit position and the second limit position;

wherein the method comprises:
controlling the air outlet assembly to oscillate between the first limit position and the second limit position and acquiring a signal emitted by the fan in real time;
in response to acquiring a first signal emitted by the fan, determining that the air outlet assembly oscillates to a position between the first limit position and the intermediate position;
in response to acquiring a second signal emitted by the fan, determining that the air outlet assembly oscillates to a position between the intermediate position and the second limit position;
and
in response to detecting a transition between the first and second signals emitted by the fan, determining that the air outlet assembly oscillates to the intermediate position.
