Further, the outside air quality sensor is installed under the front bumper of the car or at the air inlet of the car air conditioner.

This system forms multiple protections for the air in the car, which are:

The air quality sensor outside the vehicle detects the state of the air outside the vehicle. When the air quality outside the vehicle is poor, the information is fed back to the intelligent air purification controller through a hard line. The intelligent air purification controller divides the air quality according to the feedback value of the air quality sensor. There are four grades of excellent, good, medium and poor. When the air quality is excellent or good, the air conditioner controller will be notified through the LIN bus information. Fresh air from outside enters the car to ensure good fresh air enters the car; when the air quality is detected to be medium or poor, the air controller will switch the internal and external circulation dampers of the air conditioning box after receiving the feedback information from the air purification controller It is an internal circulation mode, which prevents the polluted air outside the car from entering the car and protects the good air environment in the car, thus forming the first layer of protection.

When the harmful gas outside the car has entered the car, or the first layer of protection is powerless against the harmful gas generated inside the car, it is necessary to use the air filter in the car to effectively purify the air inside the car. The air conditioner filter is installed in the Inside the air-conditioning box, an air-conditioning filter integrated with activated carbon and PM2.5 filter membrane is used. After the air conditioner is turned on, the air blown by the blower passes through the air-conditioning filter to effectively filter PM2.5, formaldehyde, xylene, and pungent odors in the car. The air-conditioning internal circulation mode has a better purification effect, which forms the second layer of protection.

The air quality control system in the car not only removes toxic and harmful gases, but also needs to provide customers with better air quality. This system is equipped with an air gain unit, and the negative ion generator is installed near the air outlet. The negative oxygen ions generated by the cutting-edge DC high voltage, It can not only settle dust and sterilize, but also improve the function of human lungs, promote metabolism, stimulate the central nervous system, refresh people, and enhance resistance; the electric air fragrance box is installed near the air outlet, and the car is equipped with different flavors of perfume , to meet the individual needs of different customers; the car is equipped with an oxygen generator to release oxygen when needed, relieve passenger fatigue, increase body immunity, and improve sub-health status. The negative ion generator, electric fragrance box, and oxygen generator are connected to the intelligent air purification controller through hard wires, and can be manually selected to be turned on/off or turned on and off together with the vehicle's air conditioner, thus forming the third layer of protection.

The air purification system is controlled and displayed through the intelligent air purification controller to provide passengers with a good interior space environment. Through the infotainment large screen, you can intuitively understand the air quality status inside and outside the car and the air purification effect, and improve the sense of quality and technology of the whole car. The intelligent air purification controller feeds back the air quality information to the air conditioner controller through the LIN bus, and the air conditioner controller communicates with the CAN bus information through the gateway and the infotainment screen, and displays the air quality status information outside the car on the infotainment screen from time to time. You can intuitively understand the air quality status (excellent/good/medium/poor) outside the car through the large infotainment screen. The intelligent air purification controller connects the gateway and the instrument through the air conditioner controller for information interaction, obtains the current vehicle mileage information, and feeds back the reminder that the air conditioner filter needs to be replaced through the large infotainment screen. For example, it is recommended to replace it once every 10,000 kilometers. The use environment of weekday models is relatively harsh, so it is recommended to replace them in advance.

The PM2.5 concentration sensor in the car is used to detect the PM2.5 concentration in the car. It is connected to the intelligent air purification controller through a hard line, and the information is constantly notified to the intelligent air purification controller. The intelligent air purification controller communicates with the air conditioning controller through the gateway. The infotainment large-screen information interaction displays the PM2.5 concentration information in the car from time to time. You can understand the current PM2.5 concentration status in the car intuitively and understand the air purification effect in the car through the PM2.5 concentration drop curve.

When the three functions of negative ion generator, electric fragrance box and oxygen generator are turned on in the large infotainment screen, different animation effects are displayed. Customers can intuitively understand the on and off status of the three devices, and It can improve the sense of quality and technology of the whole vehicle, and enhance the driving pleasure. Tips on how to use the air conditioner in a healthy way are reminded through the large infotainment screen, which can effectively reduce the musty smell and create a good driving environment. For example, when you are about to arrive at your destination, turn off the compressor a few minutes in advance to let the air blown by the air conditioner blower dry the evaporator, which can effectively reduce the musty smell; Blow it clean to avoid the accumulation of foreign matter and produce peculiar smell.

Compared with the prior art, the present invention forms multiple protections for the air in the car through the connection and control of the various components, so that the air quality in the car can be intelligently controlled, bringing better experience to the user and satisfying the needs of the user. more stringent requirements.
