After working for 30 seconds, according to the haze index detected by the pm2.5 detection unit, the voice broadcast unit starts to broadcast the quality of air in the vehicle through the processing of the micro control unit. After the pm2.5 detection unit works, monitoring in real time, and broadcasting air pollution voice when the haze index exceeds 100 so as to remind a client to start working by opening an internal circulation instant negative oxygen ion generator; the working mode of the device is that a Bluetooth receiving unit receives a mobile phone signal, a voltage regulating circuit inputs voltage to the negative oxygen ion generator through a micro-control unit, the negative oxygen ion generator runs, and a required purification mode is selected through a mobile phone.
And the Pm2.5 detection unit detects in real time, and informs a client that the air in the vehicle is good when the haze index is lower than 30. When the haze index is lower than 20, timing is started to be carried out for 60 minutes, the haze index is lower than 20, the micro control unit sends an instruction to the voice broadcasting unit, and the voice broadcasting unit broadcasts the voice of the oxygen ion generator with overlong working time.
Once the pm2.5 detection unit starts working, the pm2.5 detection unit is accumulated and timed, and after 360 hours, the pm2.5 detection unit sends a signal, controls the voice broadcasting unit through the micro control unit, starts broadcasting and changes the voice of the dust collecting net, and reminds a client.
