Protection device and device for harmful bacteria and viruses in densely populated area

Abstract

The invention discloses a protection device and device for harmful bacteria and viruses in a densely populated area. The protection device comprises a sealed room for allowing one person to stay alone, and a door, an air inlet and an exhaust pipe are arranged on the sealed room. A negative-pressure air suction cavity connected with the exhaust pipe is arranged in the sealed room, and the negative-pressure air suction cavity is formed near the mouth and nose of the person. Spray and aerosol are prevented from escaping out of the negative-pressure air suction cavity, and the spray and the aerosol generated by personnel are fast collected. The protection device for the harmful bacteria and viruses in the densely populated area further comprises a first bacterium removing device for removing the viruses and harmful germs contained in air sucked in by the air inlet and a second bacterium removing device for removing the viruses and the harmful germs contained in air exhausted out of the exhaust pipe. According to the protection device and method, the problem of cross infection can be solved well; and the person does not need to wear a mask in the sealed room for allowing one person to stay alone, airflow in the sealed room is smooth, the breathing comfort is good, and the technical problem that long-time wearing of the mask is likely to cause discomfort is solved.

Description

technical field [0001] The invention relates to the technical field of germ and virus protection, in particular to a protection method and device for protecting harmful bacteria and viruses in densely populated areas. Background technique [0002] People often relax or work in densely populated areas such as open dining areas and collective office areas. In densely populated areas, people carrying harmful germs and viruses will produce aerosols and droplets carrying viruses and germs in the surrounding environment when they talk, cough, etc. If these aerosols and droplets carrying viruses and germs are not dealt with in time Foam can cause cross-infection problems. [0003] In the prior art, in order to prevent cross-infection, people often protect by wearing a mask, but wearing a mask for a long time will cause discomfort to people. In this regard, how to create a comfortable space and avoid cross-infection of viruses and germs has become a technical problem. Contents o...
