Embodiment Construction

[0011] Please refer to figure 1 and figure 2 , is a schematic structural diagram of the air cleaning device 100 provided in the first embodiment of the present invention. The air cleaning device 100 includes a roller 101 and a light source 103 .

[0012] The roller 101 includes a body 1010 and a plurality of blades 1011 disposed on the body 1010 .

[0013] The extension direction of the plurality of blades 1011 and the extension direction of the roller 101 are both in the direction of the central axis OO'. The plurality of blades 1011 are coated with a photocatalyst layer 102 . Preferably, the body 1010 of the roller 101 is also coated with a photocatalyst layer 102 .

[0014] In this embodiment, the photocatalyst layer 102 is titanium dioxide, and the titanium dioxide includes at least one of chromium (Cr), vanadium (V), carbon (C), nitrogen (N) and sulfur (S). The photocatalyst layer 102 can undergo photocatalytic decomposition under the irradiation of visible light. ...

Abstract

The invention relates to an air cleaning device, which comprises a roller wheel, a photocatalyst layer and a light source. The roller wheel comprises a body and a plurality of blades on the body; the roller wheel can rotate in the space to drive the air to flow; the photocatalyst layer is coated on the blades; the light source is arranged oppositely to the roller wheel; and the light given off by the light source can be irradiated to the photocatalyst layer.

Description

technical field [0001] The invention relates to an air cleaning device. Background technique [0002] At present, environmental pollution has become a problem that cannot be ignored. Indoor pollutants are mainly various volatile organic compounds, most of which are carcinogens. [0003] Traditional air purifiers mainly use filtration and adsorption systems to remove pollutant particles in the air to achieve the purpose of purification. However, the above method has poor purification effect on pure gaseous organic pollutants existing in the environment, such as formaldehyde and benzene. For details, please refer to Ashok Chaurushia et al., who applied on February 6, 1997 and published on August 19, 2003, US Patent No. 6,607,573B1, entitled Portable air pollution control apparatus. [0004] Therefore, in recent years, the ozone method and activated carbon method have been used for air purification. Ozone has a strong oxidizing property and is easy to oxidize organic pollut...
