An air filter assembly and an air purifier

technical field

The utility model relates to the field of air purifiers, in particular to an air filter assembly and an air purifier.

Background technique

With the improvement of people's living standards brought about by China's economic development and the awareness of indoor air pollution, in order to quickly improve the air quality in the living environment, air purifiers have gradually become the first choice for families to improve air quality.

Air purifier, also known as air cleaner, refers to the ability to absorb, decompose or purify various pollutants, generally including particulate matter (such as PM2.5), pollen, formaldehyde, TVOC (Total Volatile Organic Compounds, total volatile organic compounds), odor , bacteria and viruses, etc., which help to improve indoor air quality and ensure human health. Because smog has become the focus of public attention, the main function of existing air purifiers is to remove particulate matter pollution and mainly use high-efficiency filters that meet the HEPA (High efficiency particulate air, high-efficiency air filtration) standard to purify the air. Some purifiers have auxiliary functions In addition to formaldehyde, sterilization and other functions.

Due to the diversity of air pollution in the home, there are mainly two major pollutants, one is particle pollution, and the other is formaldehyde and TVOC brought by decoration and furniture, which are typical volatile gas pollution. Most of today's air purifiers have poor purification performance on volatile gas pollution, and are prone to adsorption and saturation, resulting in a short life of the filter material, which cannot meet the needs of households for removing formaldehyde.

Furthermore, due to the development of the automobile industry, the emission of automobile exhaust has increased. Especially in summer, under sunlight, the nitrogen oxides in automobile exhaust will be decomposed into nitrogen and ozone, resulting in excessive low-altitude ozone concentration. In some developed cities in the north and south, ozone Pollution has become the second largest pollutant. And existing air purifier does not possess the function of purifying and eliminating indoor ozone.

Aiming at the technical problem that the air purifiers in the prior art cannot effectively purify volatile gases and ozone, there is currently no solution that can be solved.

The second technical solution of the utility model to solve the above-mentioned technical problems is as follows: an air purifier, comprising a box body and the above-mentioned air filter assembly, and the assembly is built in the box body.

The beneficial effects of the utility model are: by setting the ozone-removing filter layer, the ozone in the indoor air can be effectively purified, and by setting the formaldehyde-removing filter layer, the formaldehyde and other volatile gases in the air can be effectively purified, further purifying the indoor air, improving Indoor air quality improves user satisfaction.

Tuyere 108.

The distance between the air inlet 108 and the air outlet 106 of the air purifier in the prior art is relatively close, which easily leads to the phenomenon of air circulation and short circuit, thus affecting the purification effect. With the embodiment of the present utility model, the air inlet 108 of the air purifier is open For air intake, air inlets 108 are provided on the back and both sides of the air purifier. The air enters from the bottom of the purifier and passes through the primary filter layer 101, the high-efficiency air filter layer 102, the formaldehyde removal filter layer 103, and the negative ion module layer. 104, deozone filter screen layer 105, fan 107 arrive at the air outlet 106 after the air outlet 106 is connected to the air duct and the clean air is sent to the designated position in the room.
