an air purifier

technical field

The invention relates to the technical field of air purification equipment, in particular to an air purifier capable of improving air quality.

Background technique

Smog, as the name suggests, is fog and haze. But there is a big difference between fog and haze. The aerosol system composed of particulate matter such as dust, sulfuric acid, and nitric acid in the air causes visual impairment called haze. Haze is haze (haze). Fog is an aerosol system composed of large numbers of tiny water droplets or ice crystals suspended in the air near the ground. It mostly occurs in autumn and winter (which is also one of the reasons for the widespread haze weather across the country in January 2013), and is the product of condensation (or desublimation) in the air near the ground. The existence of fog will reduce air transparency and make visibility worse. If the horizontal visibility of the target object is reduced to less than 1000 meters, the weather phenomenon of water vapor condensation (or condensate) suspended in the air near the ground is called fog (Fog). .

Haze (mái), also known as haze (smog), particles such as dust, sulfuric acid, nitric acid, and organic hydrocarbons in the air can also make the atmosphere cloudy. The phenomenon in which the horizontal visibility of the target is between 1000 and 10000 meters is called mist or mist. Atmospheric humidity should be saturated when fog is formed (if a large number of condensation nuclei exist, the relative humidity may not necessarily reach 100% saturation). Because the light scattered by a fog composed of liquid water or ice crystals is not wavelength dependent, the fog appears milky or bluish-white and gray. Smog weather is a state of air pollution. Smog is a general expression for the excessive content of various suspended particles in the atmosphere, especially PM2.5 (particles with aerodynamic equivalent diameter less than or equal to 2.5 microns) are considered to cause haze. The "culprit" of the weather. With the deterioration of air quality, the occurrence of haze weather has increased, and the harm has increased. Many areas in China combine haze weather with fog as a warning and forecast for severe weather. Collectively referred to as "smog weather".

In order to avoid harm to human health caused by haze weather, people use air purification equipment to deal with and purify haze, and the existing purification equipment, such as a new type of high-efficiency indoor air automatic purification device disclosed in Chinese Patent Publication No. CN104006458A, includes a machine.
