technical field

The utility model relates to a high-efficiency household air purifier, which is used for purifying indoor air when the air is polluted and providing healthy indoor air environment for people.

Background technique

At present, the use of chemicals in room decoration has caused a serious decline in indoor air quality. Commonly used household air conditioners lack corresponding fresh air for ventilation, making the indoor environment more and more closed.

The main purification technologies are: mechanical filtration, ionization, photocatalyst, low temperature plasma, etc. Among them, the negative ion purification in the ionization purification technology can remove particulate matter in the air through ionization. At the same time, a certain amount of ozone is generated during the ionization process, which can oxidize gas pollutants and biological pollutants. Existing negative ion purifiers generally lack control measures for ozone concentration, which is likely to cause secondary pollution. Therefore, how to use negative ion ionization and technology, combined with other purification technologies, can not only remove various pollutants in the air, but also control the ozone concentration in the air at the air outlet, which has become an urgent problem for those skilled in the art.

The function of the medium-efficiency filter is to capture the charged particle pollutants ionized by the high-pressure negative ion filter and remove small particles, such as PM2.5.

The function of the gas-phase media filter is to utilize gas-phase media to absorb the ozone generated during the ionization process of the high-pressure negative ion filter, and through a catalytic oxidation reaction, effectively remove gases and biological pollutants such as formaldehyde and total volatile organic compounds (TVOC), without Ozone secondary pollution.

The function of the high-efficiency filter is to remove particulate pollutants such as PM0.3 with smaller particle diameters in the circulating air.

The sensor part can detect the content of particles and pollutant gases in the indoor air, and provide a basis for judging whether the purifier needs to be turned on and how many levels to turn on.

The function of the air inlet of the sensor is to inhale indoor air for the sensor component to detect the concentration of various pollutants in the room.
