Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

The following is a more specific example:

referring to fig. 1 and 2, the present embodiment includes a square housing and a circuit board inside the square housing; the circuit board is integrated with a micro-control unit, a Bluetooth receiving unit, a pm2.5 detection unit and a voice broadcasting unit; the Bluetooth receiving unit, the pm2.5 detecting unit and the voice broadcasting unit are respectively connected with the micro-control unit; the pm2.5 detection unit further comprises a fan, and the fan is over against the upper wall surface of the square shell; the voice broadcast unit is just opposite to the front of the square shell. And the power supply is connected with each unit to provide stable point voltage for the unit.

The pm2.5 detection unit further comprises a fan and a dust sensor, and the voice broadcasting unit comprises a loudspeaker; the fan and the loudspeaker are respectively corresponding to the top wall surface and the front wall surface of the square shell; the circuit board is fixed on the rear wall surface of the square shell; air outlet holes are formed in the left side wall surface and the right side wall surface of the square shell, an air inlet hole is formed in the top wall surface of the square shell, and a sound outlet hole is formed in the front wall surface of the square shell; a power line used for connecting a power supply is further extended from the left wall surface of the square shell, and a power supply connector is arranged at one end of the power line outside the square shell.

Air outlet holes for air outlet are formed in the left side wall face and the right side wall face of the square shell.

Referring to fig. 3 to 6, the unit circuits are connected as shown in the figure, wherein the micro control unit adopts a chip model of STC8F2K1682_ SOP16, and the relay model is Pin HDR1X 4.

The chip model of the Bluetooth receiving unit is YL 31; the pm2.5 detection unit adopts a dust sensor with the model number of DSTd 01-F-F5-A; the chip model that the voice broadcast unit adopted is NV3P 065.

The negative oxygen ion generator is connected with the embodiment, and comprises two working modes, namely a standard purification mode and a powerful purification mode for 120 minutes respectively. The standard purification mode is as follows: the high level for 30 minutes, the low level for 10 minutes, the high level for 20 minutes, the low level for 15 minutes, the high level for 15 minutes, and the low level for 20 minutes are chronologically arranged. After the logic of the standard purification mode is finished, the haze index exceeds 100, the high-level operation lasts for 30 minutes, whether the haze index exceeds 100 is judged, if the haze index exceeds the following operation for 30 minutes, and the circulation is repeated until the haze index is lower than 100.

The powerful purification mode is that the high level works for 120 minutes, after the high level works, the haze index exceeds 100, the high level works for 30 minutes, whether the haze index exceeds 100 is judged, and if the haze index exceeds 30 minutes of continuous working, the haze index is known to be lower than 100.

The utility model discloses a theory of operation:

the client directly links to the bluetooth receiving element through the cell-phone, and the haze index that pm2.5 detecting element surveyed is shown in real time to the cell-phone carries out instruction input to the micro-control unit.

When the haze index in the automobile is observed to be too high by using the mobile phone, a remote control command is processed by the micro-control unit, and a signal is input into the pm2.5 detection unit to start working; meanwhile, the micro control unit inputs a signal to the voice broadcasting unit to make the voice broadcasting unit send out a starting-up voice and inform a client.

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.
