when the ozone sensor detects that the indoor ozone concentration reaches 20mg/m3Then, it means that the microorganism can be killed by ozone and continuously released into the airOzone is put into the container for a certain time, so that more than 90% of microorganisms can be killed. In this embodiment, the first preset time is 30 minutes, that is, when the ozone sensor detects that the indoor ozone concentration is greater than the preset first ozone concentration threshold, the discharge time of the ozone/oxygen mixed gas is controlled to be 30 minutes, so that the ratio of killing natural bacteria reaches more than 90%, and the disinfection is completed. And then the ozone-oxygen preparation module is controlled to convert the ozone/oxygen mixed gas into pure oxygen to be discharged indoors, so that an oxygen bar mode is provided, the ozone concentration is reduced, personnel can conveniently enter the rooms, and the disinfection time is saved.
In step S40, when the pure oxygen gas discharging time is equal to the second preset time, the ozone-oxygen preparing module is turned off.
After the indoor microorganisms are killed by the ozone, the ozone decomposition tank starts to work to release pure oxygen, and after the pure oxygen is discharged for a period of time, the ozone and oxygen preparation module is closed, namely the ozone generator, the second electromagnetic valve and the exhaust fan are closed. In this embodiment, the second preset time is selected to be 5 minutes, so that on one hand, the oxygen content of the indoor air is increased, and on the other hand, the smell left after ozone disinfection can be eliminated, so that the air is fresher and more pleasant.
