The negative pressure purification sterilizer that this embodiment provided has included disinfect box 110, disinfection subassembly 120, negative pressure fan 130 and air inlet piece 140, can set up the negative pressure purification sterilizer that this embodiment provided in the top in the office area in the use, for example with negative pressure purification sterilizer setting in service window department, then set up air inlet piece 140 between office staff and public service staff, open negative pressure fan 130, negative pressure fan 130 can produce the negative pressure, with form the air curtain in air inlet piece 140 department, inhale disinfect box 110 with the droplet that office staff and public service staff produced in the speaking process, droplet and virus are discharged disinfect box 110 again after entering disinfect subassembly 120 through disinfection subassembly 120 along with the air current, and then can avoid office staff and public service staff to produce cross virus infection, and is particularly suitable for hospital, bank, cashier's desk, public transport ticket window and government service window.
It will be appreciated that the presence of hospital infectious diseases is a relatively complex, high-risk environment, with the probability of hospital workers contracting infectious diseases being higher than non-medical workers. Medical workers deal with different disease types of hospital treatment every day, and part of patients are not excluded from carrying disease-source viruses, which brings great challenges to the medical workers. When doctors in the clinic visit, patients come from different places and different disease types. However, the flow of seeing and curing diseases in hospitals is almost the same, and the processes of looking, smelling, asking and cutting are almost all performed. The important link is that doctors and patients can know the illness state in close contact. In this process, the distance between the doctor and the patient will be a table distance, and the spray will be effectively transmitted in this distance during double talk, if any one party is a respiratory tract infection carrier, there is a risk of infection for the person sitting on the other party, the doctor is the first victim group, and after the doctor is infected, there is an opportunity to infect the next patient to be asked. Therefore, it is the gist of this patent to address the infectious agent spray in desktop conversation scenarios. Hospital registration windows, billing windows, clinical laboratory windows, blood drawing windows, service desks, etc., receive a large number of patients for diagnosis each day. In the link of both sides contact, both sides can produce the conversation, and in the conversation, because window position can receive the influence of air current, the air can flow to the opposite side direction, if arbitrary one has respiratory tract infection source such as influenza, typhoid, hepatitis B, new crown, there is the risk of infecting the opposite side.
