Fan with purification function

Abstract

The invention discloses a fan with a purification function. The fan comprises a driving unit, fan blades, a front protection cover, a rear protection cover and a filter purification unit attached to the interior of the front protection cover. The driving unit drives the fan blades to rotate, and the driving unit and the fan blades are arranged in space formed by the front protection cover and the rear protection cover; the fan blades drive circulation air to to treated through the filter purification unit, and the filter purification unit comprises a first adsorption component, a catalytic component and a second adsorption component which are stacked in a front-and-back manner. After benzene, methylbenzene, xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde and acrolein in air in a building is removed through a catalyst, the concentration can be below 0.05 milligram / cubic meter, and meanwhile, the content of microorganisms in the circulation gas can be obviously reduced.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a fan with a purification function. Background technique [0002] At present, with the development of the economy, there are more and more smog weather in major cities in China. With the increase of smog weather, the quality of indoor air is also declining. [0003] Haze, 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 that the horizontal visibility of the target is 1000-10000 meters is called light fog or mist (Mist). Atmospheric humidity should be saturated when fog is formed (if there are a large number of condensation nuclei, saturation may occur if the relative humidity does not necessarily reach 100%). Fog made of liquid water or ice crystals scatter light that is independent of wavelength, so fog appears milky or bluish-white and gray. Sulfur d...

Problems solved by technology

[0010] (3) Hazy weather can also lead to the weakening of ultraviolet rays near the ground, which will increase the activity of infectious bacteria in the air and increase the number of infectious diseases

[0011] (4) Not conducive to children's growth

However, in interior decoration and furniture, it is inevitable to use various glues or paints, which leads to the emission of various organic pollutants, such as formaldehyde, benzene and other substances in the room.

[0013] At present, for the treatment of these indoor pollutants, various air purifiers and activated carbon adsorption are mostly used, but the increase of these devices will occupy the indoor area, thereby increasing the cost

[0014] The existing fans are only used to rotate the air and bring about the circulation of the air. The fans on the market do not have any purification function
