Under the requirement of production quality management specifications, industries such as medicine, semiconductor, food processing and the like have strict control requirements on environmental suspended particles and microorganisms in production places and experimental places. For example, aseptic production of medicines can be realized only by relying on a dust-free workshop, suspended dust in air is controlled, and the number of living microorganisms is also controlled, so that a stable and reliable disinfection procedure is an important link for ensuring production quality. At present, in order to prevent external personnel from bringing pollutants into a clean area, most enterprises adopt a method of arranging an air shower between the clean area and a non-clean area to remove dust on the surfaces of the personnel and goods so as to achieve the purpose of purification. Most of the air shower products in the market only provide high-speed clean air flow to blow off dust carried by people, and do not have the function of sterilization. A large amount of dust and germs carried by the dust are accumulated on a filter screen in the air duct, and secondary pollution is easily caused. A small part of air shower products provide a bactericide spraying device, and a bactericide can be sprayed to the surface of a human body or an object after being atomized for disinfection treatment. The method has the defects that the method needs to continuously supply the drug consumables such as disinfectant and the like, is harmful to human bodies, has low sterilization efficiency, and needs to spend longer treatment time or occupy larger working sites during implementation because the spray sterilization link needs to be carried out after dust removal. Generally, the air shower is also provided with a sterilizing device such as an ultraviolet lamp, and because ultraviolet light and ozone excited by the ultraviolet light have great harm to human bodies, the method can only carry out static sterilization in the air shower under the unmanned condition and cannot dynamically sterilize in the presence of people.
