Vortex air duct for air cleaning device and air cleaning device

Abstract

The embodiment of the invention provides a vortex air duct for an air cleaning device and the air cleaning device. The vortex air duct comprises a catalyst body, wherein the catalyst body is constructed to be an air duct structure and is provided with an air duct inlet and an air duct outlet, and a rough surface structure is constructed on the inner side of the catalytic body and used for making friction contact with air so that the air can be converted into an air vortex shape. The air cleaning device comprises a shell, a fan, a light source and the vortex air duct for the air cleaning device. According to the vortex air duct for the air cleaning device and the air cleaning device, the rough surface structure is constructed on the inner surface of the catalyst body, so that friction forceis generated when the rough surface structure makes contact with the air; and air flow forms air vortex flow moving forwards in a rolling mode along the inner wall of the rough surface structure andcontinuously moves forwards in a rolling mode, so that the air makes contact with the inner surface of the catalyst body more easily, and then the pollutant decomposition efficiency and the bacterialvirus killing rate are improved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a vortex air duct used for an air cleaning device and the air cleaning device. Background technique [0002] The objects of air cleaning technology are mainly for particle pollutants in the air (such as PM2.5, etc.), chemically harmful gaseous pollutants (such as formaldehyde, benzene, TVOC, etc.), bacteria and viruses floating in the air. For the air cleaning of particulate pollutants, HEPA high-efficiency filter technology is mostly used at present, which can filter out particulate pollutants ≥0.1um and above. Many technologies are used to kill chemically harmful gaseous pollutants in the air and bacteria and viruses in the air, such as activated carbon adsorption, plasma decomposition, ozone disinfection and sterilization, and catalytic decomposition and disinfection. [0003] HEPA filter technology has a large wind resistance, and the filter screen needs to be repla...
