s105: when the electric sliding block is used again, the processor outputs a second moving signal to the driving device, and the driving device drives the electric sliding block to move downwards for a preset distance;
s106: the processor outputs a second rotation signal to the driving device, and the driving device drives the rotating device to rotate downwards by a preset angle;
s107: the processor outputs working signals to the driving device, the driving device drives the motor to start, and the fan blade rotating shaft drives the bearing to rotate.
7. The method of claim 5, wherein the ceiling fan comprises: further comprising:
the temperature sensor detects a temperature value of the environment around the ceiling fan and sends the temperature value to the processor;
the processor extracts the rotating speed of the ceiling fan corresponding to the temperature value;
the processor outputs a speed regulating signal to a first speed regulating device, and the first speed regulating device regulates the ceiling fan to the rotating speed.
8. The method of claim 7, wherein the ceiling fan comprises: further comprising:
the processor judges whether the rotating speed is greater than or equal to a preset rotating speed;
if so, the processor outputs a rising signal to the driving device, and the driving device drives the lifting pin to rise by a preset height;
the processor outputs a third rotation signal to the driving device, and the driving device drives the rotating platform to start;
the processor obtains the rotating speed of the ceiling fan and sets the rotating speed as the parameter of a second speed regulating device, and the second speed regulating device regulates the rotating platform to the rotating speed.
