Problems solved by technology

These pollutants can cause the occupants of the car to feel uncomfortable in light, and endanger their health in severe cases.
[0003] At present, most of the treatment methods for harmful air in cars use perfume to cover up or activated carbon packs to absorb. Perfume cannot remove harmful gases from the source, and human health is still damaged by harmful gases; because the air in the car does not circulate when the windows are sealed. , so the effect of fixing the activated carbon bag on a certain place of the car to absorb harmful substances in the air inside the car is not very obvious
[0004] Patent No. CN104964353A discloses an air purification method, which uses negative ions to decompose harmful gases in the air, and the decomposed harmful gases are removed by odor scavenger, but odor scavenger is more of an air freshener, which can freshen the air , but cannot essentially remove the decomposed harmful substances
[0005] Patent No. CN105214443A discloses a method of air freshener, which uses activated carbon to adsorb the air in the car. When the activated carbon is saturated, the harmful gas is desorbed from the activated carbon by thermal desorption, and then the harmful gas is adsorbed. This method can deal with harmful gases in the car, but this method has the following disadvantages: the service life of activated carbon is limited. There are harmful gases, activated carbon single-stage treatment can reduce the content of harmful gases, but the removal rate is low

Embodiment 1

[0045]Choose a new car and collect the air in the car with tenax adsorption tubes. After the air in the car is collected, use thermal desorption to desorb the gas. The desorbed gas is detected and analyzed by gas chromatography and mass spectrometry equipment. The gas composition and content data are obtained, see Table 1.

[0046] Use the air purifier of the present invention to purify the air in the car, put the air purifier on the passenger seat in the car, turn on the exhaust fan of the air purifier, and close the car window, the purifying time is 2 hours, and the air purifying ends Afterwards, the air in the car was collected again with the tenax adsorption tube. After the air in the car was collected, the gas was desorbed by thermal desorption. The desorbed gas was detected and analyzed by gas chromatography and mass spectrometry equipment, and obtained Gas composition and content data are shown in Table 1.

Embodiment 2

[0048] Choose a new car again, the gas collection and air purification methods are the same as in Embodiment 1, the difference is that the degreased cotton and solid air freshener are removed in the air cleaner, and other conditions are the same.

Embodiment 3

[0050] Choose a new car again, the gas collection and air purification mode are the same as embodiment 1, the difference is that there is no water and olive oil in the air cleaner, and other conditions are the same.

[0051] The gas composition and content data in the car obtained from the gas chromatography and mass spectrometry analysis obtained in Examples 1-3 are shown in Table 1.

[0052] Table 1

[0053]

[0054] As can be seen from the data in Table 1, in the embodiment, before and after purification, the content of nitrogen and oxygen gas remains unchanged. Since nitrogen and oxygen are the main components in the air, the proportion in the air is very large, so the removal of a small amount of harmful gases Except, there is no effect on the ratio of nitrogen and oxygen.

[0055] In Example 1-3, after being purified by an air purifier, the content of harmful gases in the purified air decreased significantly:

[0056] In Example 1, the removal rates of formaldehyde,...

Abstract

The invention relates to a vehicle-mounted air purifier. The vehicle-mounted air purifier comprises a replaceable filter element, a housing main body and two rubber rings; the housing main body comprises a shell, a breathable external ring, a filtering grille, a micro motor, an exhaust fan and a rechargeable lithium battery; and the replaceable filter element comprises a shell cover, a non-woven fabric air filtering cotton, granular active carbon, a multi-tube exhaust circular disc, sponge, a water layer, an oil layer, absorbent cotton, a solid air freshener and a metal net. The air purification of the vehicle-mounted air purifier main comprises the following steps of non-woven fabric air filter cotton filtering, granular active carbon adsorption, liquid absorption and air degreasing. According to the vehicle-mounted air purifier, dust, formaldehyde, benzene, methylbenzene and dimethylbenzene in the air in a vehicle can be sufficiently removed, and the air can be perfumed so that the air is fresh and pleasant.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a vehicle-mounted air cleaner. Background technique [0002] Cars contain a lot of plastic products, so they will release a lot of harmful gases, such as benzene, toluene, xylene, formaldehyde and so on. These pollutants can cause the occupants of the car to feel uncomfortable in light, and endanger their health in severe cases. [0003] At present, most of the treatment methods for harmful air in cars use perfume to cover up or activated carbon packs to absorb. Perfume cannot remove harmful gases from the source, and human health is still damaged by harmful gases; because the air in the car does not circulate when the windows are sealed. Therefore, it is not very obvious to fix the activated carbon bag in a certain place of the car to absorb harmful substances in the air inside the car. [0004] Patent No. CN104964353A discloses an air purification method, which uses negative i...
