Method and device for protecting harmful bacteria and viruses in densely populated area

Abstract

The invention discloses a method and a device for protecting harmful bacteria and viruses in a densely populated area, and belongs to the technical field of pathogenic bacteria and virus protection. According to the protection method, a single person enters a closed room for the single person so as to be subjected to cross infection protection. The protection device comprises a closed room where the single person is located alone, wherein a door, an air inlet and an exhaust pipe are arranged on the closed room; a negative pressure air suction cavity connected with the exhaust pipe is formed inthe closed room; a first sterilization device is arranged at the air inlet; and a second sterilization device is arranged on the exhaust pipe. According to the method and the device for protecting the harmful bacteria and the viruses in the densely populated area provided by the invention, by arranging the closed room where the single person is located alone, air entering the closed room and airexhausted out of the closed room are treated through the sterilization device, so that the air entering the closed room and the air exhausted out of the closed room are safe, a comfortable and safe environment space can be provided for people in the densely populated area, and pathogenic bacteria and virus cross infection is prevented. The protection device provided by the invention is reasonablein structure and low in cost, and the protection device and method are suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of protection against germs and viruses, in particular to a protection method and protection device for harmful bacteria and viruses in densely populated areas. Background technique [0002] Today, with the development of medicine, epidemic viruses and germs still seriously threaten human health. At present, epidemic viruses, such as influenza virus and new coronavirus, are mostly spread through oral droplets in patients' coughs, sneezes and speech. People often relax or work in densely populated areas such as open dining areas, collective office areas, railway stations, airports, hospitals, shopping malls, etc. In densely populated areas, people carrying harmful germs and viruses will carry viruses and germs in the surrounding air when they speak loudly, cough, sneeze, etc. If these aerosols and droplets carrying viruses and germs are not dealt with in time, Can cause cross-infection problems.

AI Technical Summary

Problems solved by technology

Since the mask has to be removed when eating and drinking in crowded areas, the mask cannot achieve the protective effect during the meal

Especially in some special places such as the dining area of ​​high-speed rail trains, although the problem of preventing cross-infection can be solved by using the air-sterilized single-person dining room with the existing technology, the high-frequency use of different people will cause cross-infection. Problems such as infection, wind noise and discomfort cannot be solved by existing technologies

In the same dining area in the high-speed rail dining area, the next person may use it 2 to 3 seconds after the previous person uses it. If the air is disinfected or sterilized by filtration, it is necessary to ventilate in such a short period of time. The wind noise generated is unacceptable to dining staff; and if disinfectant spray is used to disinfect or sterilize the air, the impact of the disinfectant on the dining environment cannot be eliminated in such a short period of time; if plasma or ultraviolet rays are used to disinfect the air or sterilization, the air cannot be effectively disinfected or sterilized in such a short period of time

The current methods of preventing cross-infection through disinfection or sterilization in such special places cannot solve the problem of preventing cross-infection of diners

[0004] In addition, wearing a mask for a long time will cause discomfort, especially the droplets produced by sneezing will adhere to the inner surface of the mask, causing extreme discomfort, and the filtering effect of the mask itself will be affected by stretching and rubbing during wearing. Influence, its performance will also decrease with the prolongation of use time, not enough to achieve the effect of completely blocking infection
