Regarding these things about the car air disinfection machine, these points are very important

　　Affected by the epidemic, the air quality of vehicles has also become a topic of close attention to vehicle users. New words such as "healthy car" and "AQS intelligent air purification system" have frequently appeared on various online media. In addition, the main issues that people pay attention to when buying cars have also changed. They not only include the peculiar smell and chemical pollution in the car, but also increase the concern about microorganisms such as bacteria in the car, which is mainly reflected in the car air conditioner. The needs of the air system have changed.

　　Regarding the issue of improving the air quality in the car, is it the new air outlet or the heat that will not follow? The interior space of a car varies greatly depending on the vehicle model. One is a small family car with 2-7 seats; the other is a truck with 2 to 3 seats; the third is a passenger car and bus with 8-40 people. On the one hand, vehicles with 7 seats or less have a small internal space and a small number of passengers. The windows of the vehicle can be opened for ventilation for up to 60s; on the other hand, large passenger vehicles and buses have large internal spaces and carry a small number of passengers. The number of people is relatively large, but it takes only a short time to ventilate the interior of the car. In addition, existing cars themselves are equipped with air systems such as air conditioning. So, why install an air disinfector under the existing air conditioning system? This will be a concern for vehicle users and manufacturers, and how effective such a "healthy car" is in air disinfection.

　　According to data, the GB/T27630-2011 "Guidelines for the Evaluation of Air Quality in Passenger Cars" released in 2011, the guidelines are constantly being improved with the changes in the automotive market. This is the regulation of the internal air quality of vehicles from the macro level, and from the micro level, many automobile manufacturers have also established their own air quality systems. Such as Geely ICON "all-round health car", Changan Automobile produces "PM0.1" composite antibacterial and antivirus high-efficiency filter, SAIC Motor's first deep ultraviolet "antivirus" car air conditioner and so on. The high quality of the air in the car is pushing the basic content of vehicle production, and it will also stimulate the corresponding "air purification" manufacturers to carry out corresponding research and development, production, etc., such as the B-150 and 250 car air under the brand of IFEJingbao. Disinfection machine.

　　Compared with the indoor air disinfection machine, the vehicle-mounted air disinfection machine requires smaller volume and faster wind speed in order to complete the air circulation in the car in a shorter time, thereby achieving a comprehensive sterilization effect. For the vehicle-mounted air disinfection machine, it is also equipped with AQS management system, coarse and high-efficiency filter, honeycomb activated carbon filter, negative ion or plasma generator, ultraviolet sterilization equipment, photocatalyst and other multi-functional air disinfection machines that meet the requirements of disinfection.

　　Regarding ultraviolet disinfection, UVC ultraviolet rays with a wavelength of 253.7nm are used to destroy the DNA or RNA structure of bacteria, fungi and other microorganisms, so that cells can no longer grow, and then achieve the effect of sterilization. However, ultraviolet rays with a wavelength between 200 and 275 nm have weak penetrating power, and most glass or plastics cannot pass through, and it is more harmful to human skin. Therefore, the use of UVC ultraviolet disinfection should be avoided as much as possible Ultraviolet rays hit the skin of the body directly.

　　Regarding the activated carbon filter, it is mainly based on the adsorption of carbon. The filter used in combination with nano mineral crystals has a better adsorption effect. The filter should be exposed to the sun in time to improve the activity of the carbon.

　　Regarding plasma or negative ion disinfection, the corresponding electrons (e-) are generated through a specific generating device. When the ions are combined with the microbial organism, it will cause the microbial organism to mutate and become inactivated.

　　To sum up, vehicle users can choose the appropriate air disinfection system according to their own conditions, the air disinfection and purification effect of the general HEPA high efficiency filter + activated carbon filter + UVC ultraviolet + photocatalyst + plasma or negative ion vehicle air disinfection machine It can meet the air quality requirements in the car.
