If the air conditioner product stops working, the wind speed is smaller than the wind speed parameter, the wind speed sensor is triggered again to send an electric signal, the controller can send a control command to control the ultraviolet lamp power supply to be disconnected, the ultraviolet lamp light is turned off, therefore, the filter assembly can automatically disinfect air flowing in during working, the disinfection and sterilization function is automatically turned off when the filter assembly does not work, the ultraviolet lamp power supply does not need to be manually turned on or turned off, and therefore energy conservation is achieved.
Preferably, 0.85 ≦ Vs/V ≦ 0.95.
The minimum wind speed is the flow speed of air flowing through the filter when the fan of the ventilation equipment such as an air conditioner works at the lowest rotating speed, the wind speed parameter is set to be slightly smaller than the minimum wind speed, the sensitivity of the sterilization device can be ensured, the sterilization device can be started in time when the air conditioner is started, meanwhile, the problem of misjudgment caused by the fact that air flows through the filter when the air conditioner is not started can be avoided, and the reliability of the sterilization device in the working process is ensured.

In one embodiment, the step of detecting whether the operating state of the filter assembly satisfies a first preset condition comprises: detecting the humidity change rate of an air outlet of ventilation equipment applied to the filtering component; when the humidity change rate of the air outlet is greater than or equal to a third preset value, judging that the working state of the filtering assembly meets a first preset condition; and when the humidity change rate of the air outlet is smaller than a third preset value, judging that the working state of the filtering assembly does not meet a first preset condition.
In one embodiment, the step of detecting whether the operating state of the filter assembly satisfies a first preset condition comprises: detecting whether ventilation equipment applied to the filtering component is in an open state; when the ventilation equipment is in an opening state, judging that the working state of the filtering component meets a first preset condition; when the ventilation equipment is in a closed state, the working state of the filter assembly is judged not to meet a first preset condition.

14. The control method according to claim 13, wherein the step of detecting whether the operating condition of the filtering assembly satisfies a first preset condition comprises:
detecting the wind speed of the airflow passing through the filter;
when the wind speed is greater than or equal to a first preset value, judging that the working state of the filtering assembly meets a first preset condition;
and when the wind speed is less than a first preset value, judging that the working state of the filtering component does not meet a first preset condition.
15. Control method according to claim 14, characterized in that the first preset value Vs is less than the minimum wind speed V through which the filtering assembly passes when it is in operation.
16. The control method according to claim 15, characterized in that 0.85 ≦ Vs/V ≦ 0.95.
17. The control method according to claim 13, wherein the step of detecting whether the operating condition of the filtering assembly satisfies a first preset condition comprises:
detecting the temperature change rate of an air outlet of ventilation equipment applied to the filtering component;
when the temperature change rate of the air outlet is greater than or equal to a second preset value, judging that the working state of the filtering assembly meets a first preset condition;
and when the temperature change rate of the air outlet is smaller than a second preset value, judging that the working state of the filtering assembly does not meet a first preset condition.
18. The control method according to claim 13, wherein the step of detecting whether the operating condition of the filtering assembly satisfies a first preset condition comprises:
detecting the humidity change rate of an air outlet of ventilation equipment applied to the filtering component;
when the humidity change rate of the air outlet is greater than or equal to a third preset value, judging that the working state of the filtering assembly meets a first preset condition;
and when the humidity change rate of the air outlet is smaller than a third preset value, judging that the working state of the filtering assembly does not meet a first preset condition.
19. The control method according to claim 13, wherein the step of detecting whether the operating condition of the filtering assembly satisfies a first preset condition comprises:
detecting whether ventilation equipment applied to the filtering component is in an open state;
when the ventilation equipment is in an opening state, judging that the working state of the filtering component meets a first preset condition;
when the ventilation equipment is in a closed state, the working state of the filter assembly is judged not to meet a first preset condition.
