Description

technical field [0001] The invention relates to a vehicle-mounted air purification and negative ion generator, belonging to the technical field of vehicle products. Background technique [0002] With the improvement of technology and people's quality of life, the number of domestic cars is growing continuously, and more and more car interior decorations and leather products appear on the car. At the same time, the content of harmful substances in the air in the car is also increasing. According to the survey, 33 of the 93 new cars have exceeded the standard of formaldehyde, and among the 200 used cars, 90% of the cars have seriously exceeded the harmful gas content of TVOC, and this kind of harmful gas has serious carcinogenic and other harmful effects on the human body. Induced hazards of serious illness. [0003] Even so, the problem of the air environment in the car has not been effectively improved. At present, the technologies used by the existing air purification devi...

Problems solved by technology

[0003] Even so, the problem of the air environment in the car has not been effectively improved. At present, the technologies used by the existing air purification devices are mainly divided into two types. One is the filter adsorption type, which mainly uses high-efficiency filters to separate the air in the environment. Dust and particulate harmful substances, but it does not have much effect on bacteria and toxic gases, and there is a saturation problem in the filtration adsorption method, the filter needs to be replaced regularly, and the consumables are not environmentally friendly

Moreover, a large number of dust particles and viruses are attached to the filter screen that has been used for a period of time, which reduces its filtration efficiency, and there is also the problem that the filter screen becomes a source of pollution due to bacterial reproduction, which restricts the development prospects of this method. The second is photocatalysis, Emerging air purification technologies such as plasma stand out for their high removal efficiency, but they also have their disadvantages

For example: photocatalytic technology is under the condition of ultraviolet light irradiation, the catalyst decomposes harmful substances through catalytic action, and the sterilization effect is good, but the purification efficiency is too low and the capacity is limited, so it is difficult to support the purification function of the device alone

As a popular technology for air pollution control, plasma technology has the characteristics of low cost, low consumption and high efficiency, but it also has the problem of producing harmful by-products and causing secondary pollution
