The invention provides a filter screen assembly and an air purifier with the same. The filter screen assembly comprises a filter screen body, the filter screen body sequentially comprises a filter screen layer and a catalyst layer in the airflow inflow direction, the catalyst layer is connected with the filter screen layer, and a heating part is arranged in the catalyst layer. The heating part isarranged in the filter screen, so that the heating function of the filter screen is realized, a high-temperature environment is provided for the filter screen, decomposition of by-products on the surface of the catalyst layer is promoted, regeneration of the catalyst layer is achieved, and the effect of purifying the filter screen by the catalyst layer can be greatly prolonged. After the high-temperature environment acts for a period of time, germs, mites and the like infected by the respiratory tract can be killed, and secondary pollution caused by breeding of microorganisms on the surface ofthe filter screen is avoided. Some microorganisms can generate a large number of secondary metabolites during mass propagation, so that gas purified by the air purifier has peculiar smell, and breeding of the microorganisms can be killed or inhibited in a high-temperature environment. By using the assembly, the service lifetime of the catalyst can be prolonged, and user experience is improved.
Description
technical field [0001] The invention relates to the technical field of air purification equipment, in particular to a filter screen assembly and an air purifier having the same. Background technique [0002] Formaldehyde is a major indoor air pollutant that endangers human health. In order to improve indoor air quality, air purifiers are usually used to purify indoor particulate matter and formaldehyde and other pollutants. At present, chemical adsorption or formaldehyde catalytic degradation technology is mainly used to purify formaldehyde in indoor air through adsorption and destructive degradation. [0003] The formaldehyde degradation catalyst converts formaldehyde into carbon dioxide and water, has high formaldehyde purification efficiency, and has high development and application potential. However, catalysts also have many problems. After a period of use, the catalyst will be deactivated and needs to be regenerated; after a period of use, the catalyst with porous m...
