Background

Air purifier is as an air purifier, and its prevalence is higher and higher, and common air purifier adopts the filter screen of multistage to purify the air. The common filter screen mainly has an HEPA filter screen, so that dust in the air can be effectively filtered; and the activated carbon filter screen can well adsorb harmful substances such as formaldehyde in the air due to the large specific surface area of the activated carbon. Although HEPA filter screens or activated carbon filter screens can also achieve the purpose of reducing parts by physically adsorbing attachments of the HEPA filter screens or the activated carbon filter screens, the HEPA filter screens or the activated carbon filter screens cannot adsorb all harmful substances, and after filtration, the HEPA filter screens or the activated carbon filter screens are also dangerous waste products and need special treatment, otherwise, the HEPA filter screens or the activated carbon filter screens cause secondary pollution.

Ozone can kill bacteria or viruses and has been widely used in the medical field, but because ozone has the possibility of secondary pollution, the popularization of ozone in household products is limited. For the sterilization and odor removal technology, the catalyst is gradually popularized as a novel sterilization and odor removal material, and firstly, the catalyst is generally a reinforced metal oxide and can well remove bacteria attached to the catalyst; secondly, the catalyst can decompose ozone to form oxygen free radicals, and the oxygen free radicals have higher oxidizability so as to oxidize and decompose harmful substances such as bacteria and the like; thirdly, the combination form of the catalyst and the ozone also solves the problem of secondary pollution caused by ozone residue.

Therefore, in order to solve the problems, a sterilization and odor removal air purifier is urgently needed to be developed to realize safe and efficient air disinfection.
