Description
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
Haze, as the name implies, is fog and haze. But the difference between fog and haze is large. An aerosol system consisting of dust, sulfuric acid, nitric acid and other particles in the air causes visual disturbance called haze. The haze is just dust haze (the smoke clouds). Mist is an aerosol system consisting of a large number of tiny water droplets or ice crystals suspended in the air near the surface. Most of the weather occurs in autumn and winter (which is one of the reasons for 1 month in 2013 in the country of large-area haze weather), and is the product of water vapor condensation (or desublimation) in the air of the near ground layer. The presence of Fog can reduce air transparency and deteriorate visibility, and if the horizontal visibility of a target is reduced to within 1000 meters, the weather phenomenon of condensation (or desublimation) of water vapor suspended in the air near the ground is known as Fog (Fog).
Haze (m < i), also known as dust in haze (smog) air, sulfuric acid, nitric acid, organic hydrocarbons and other particles can also make the atmosphere cloudy. This phenomenon, in which the horizontal visibility of the target is 1000 to 10000 meters, is called light fog or Mist (Mist). Atmospheric humidity should be saturated as the mist is formed (saturation may occur if the relative humidity does not necessarily reach 100% if a large number of condensation nuclei are present). The fog appears milky or bluish white and gray in color because the fog of liquid water or ice crystals scatters light less strongly with respect to wavelength. Haze weather is an atmospheric pollution state, haze is a general expression of exceeding the content of various suspended particulate matters in the atmosphere, and especially PM2.5 (particulate matters with aerodynamic equivalent diameter less than or equal to 2.5 micrometers) is considered as an 'allegory' causing the haze weather. Along with the deterioration of air quality, haze weather phenomenon appears increasing, and the harm aggravates. In many areas of China, haze weather phenomena are combined into fog to be used as early warning and forecast of disastrous weather. Collectively referred to as "haze weather".
For avoiding haze weather to cause the injury to the health, people adopt air purification equipment to be used for handling and purifying haze, and among the current clarification plant, like the novel high-efficient indoor air automatic purification device that chinese patent publication No. CN104006458A discloses, which comprises a housing, a circuit board, use the air guiding device of fan as the power supply, air dust collector, anion generating device, ultraviolet germicidal device, the photocatalytic oxidation device, operating panel, wireless remote controller, the device's air purification disinfection effect is comprehensive, moreover, the steam generator is simple in structure, high efficiency, the energy consumption is low, the noise is little, the maintenance cost is economized, and long service life is long, but the device can't realize the regulation to air-purifying humidity, be unfavorable for using widely.
