Meanwhile, the third motor 10 and the fourth motor 11 will drive the first heating element 8 and the second heating element 9 to rotate, at this time, the third motor 10 will rotate clockwise, and the fourth motor 11 will rotate clockwise. Through the movement, a fan channel is formed, and the fan 3 moves downwards in the fan channel at the moment;

meanwhile, the controller controls the filter screen assembly and the heating assembly to stop, controls the fan 3 and the electric purification part 14 to start, and at the moment, the whole control purifier only performs electric purification operation but does not perform disinfection operation. After the first housing 1 moves downwards to a preset position, the position sensor is triggered, the position sensor transmits a signal to the controller, and the controller controls the motor to stop moving, so that the first housing 1 is stabilized at a specific position, and the overall height of the air purifier is reduced, as shown in fig. 2.

And a second mode: simultaneously performing air purification and sterilization operations

When purification and sterilization operations need to be carried out simultaneously, the controller controls the motor of the pushing piece to be started, and controls the filter screen assembly, the heating assembly and the electric purification assembly to be started simultaneously, and at the moment, the first shell 1 moves upwards relative to the second shell 2. When the preset position is reached, the first position sensor will be triggered, at which point the first position sensor will control the motor to stop moving, while the overall height of the air purifier will increase, as shown in fig. 1.
