When the second end 220 of the bracket 200 is mounted directly above the micro switch 121, the micro switch 121 is in an off state without being subjected to external pressure. At the moment, the current detector monitors the current value and sends an electric signal to the control chip, and the control chip controls the rotating speed of the motor to be reduced to a preset N1, so that the air volume of the purifying device is reduced and the purifying device is in a common mode.

Referring to fig. 2 to 4, in the second embodiment, the trigger part 230 disposed at the first end 210 is used to press the micro switch 121, so as to switch the micro switch 121 from the open state to the closed state, thereby switching the purification apparatus to the purification mode. When the bracket 200 is rotated 180 degrees with respect to the housing 100, the trigger part 230 and the micro switch 121 are relatively deflected by an angle, so that the micro switch 121 maintains an off state, thereby switching the purification apparatus to the normal mode. The user can reasonably select the installation position of the bracket 200 relative to the casing 100 according to the concentration of the indoor harmful substances, thereby adaptively adjusting the rotating speed of the motor and adjusting the air volume of the purification device. Meanwhile, the internal parameters of the fan unit do not need to be manually adjusted, and the convenience in use is improved.

According to the analysis of the first and second embodiments, the filtering unit embedded in the air inlet 110 of the housing 100 can filter harmful substances in the indoor air, and when the trigger 230 of the filtering unit abuts against the micro switch 121 and pushes the micro switch 121 to the closed state, the fan unit keeps the rotation speed of the fan unit to be N2 according to the state of the micro switch 121. Meanwhile, when the trigger 230 of the filter unit is staggered from the micro switch 121 and is not abutted to the micro switch 121, the micro switch 121 maintains its off state, and the fan unit maintains its rotation speed as N1 according to the state of the micro switch 121. By adjusting the relative position of the trigger 230 and the microswitch 121, the rotation speed of the fan unit can be adaptively adjusted to adjust the air speed and the air volume of the purification apparatus. The adjusting mode does not need to manually adjust the internal parameters of the fan unit, improves the convenience in adjustment, and can keep the stability of the working performance of the purifying device at different rotating speeds.

The present application provides a purification apparatus and an air conditioner, and the principle and the implementation of the present application are explained in detail by applying specific examples, and the explanation of the above examples is only for helping to understand the method and the core idea of the present application; meanwhile, for a person skilled in the art, according to the idea of the present application, the specific implementation manner and the application scope may be changed, and in summary, the content of the present specification should not be construed as a limitation to the present application.
