Description
Technical Field
The invention relates to the field of environmental protection and sanitation, in particular to a multipurpose sterilization and disinfection purifier and a working method thereof, which are mainly used for sterilization, disinfection, deodorization, fresh keeping and pesticide residue reduction of a refrigerator, can be used for sterilization, mite removal and deodorization of pillow interiors, bedding, plush and other toys, books, shoes and the like, can be independently used for fruit and vegetable sterilization, insect killing, fresh keeping, pesticide residue reduction and the like.
Background
Taking a refrigerator as an example, a common refrigerator can only slow down the propagation of bacteria but cannot sterilize, the food safety cannot be protected, and because fruits and vegetables can release ethylene, the fruit and vegetable ripening function is realized, and the fruits and vegetables can be aged for a long time, such as wrinkling, softening and the like, so that the freshness is reduced; the meat is putrefy and deteriorated during the storage process, and odor substances such as trimethylamine are generated. Various antibacterial refrigerators are put out in the market at present, different antibacterial modules are adopted, but the antibacterial refrigerators are not accepted by the users, and the functions of sterilization, deodorization and fresh keeping are long-lasting or not puzzled according to analysis except higher price. Especially, once the failure occurs, the product must be sent to a professional department for maintenance, which is costly and troublesome. Therefore, a plurality of independent modules are popular in the market, but all have shortcomings; if the activated carbon bag is adopted, although the deodorization can be realized, the sterilization cannot be realized. Moreover, the adsorption capacity is easy to saturate, and the odor can be released when the adsorption capacity is not changed in time; the refrigerator is also treated by single ozone, the ozone has extremely strong oxidizing capacity and can be competent, but the ozone can play a role only by maintaining higher concentration, the refrigerator can be opened at any time, the ozone with higher concentration can cause injury to human bodies, and especially children can cause more serious injury when opening the refrigerator door for a long time. Ozone generation by high voltage discharge is also commonly associated with the production of hazardous by-products such as nitrogen oxides which are harmful to health.
