The invention provides a device used for blocking infecting of diseases such as novel coronavirus spread by droplets. The device comprises a chemical sterilization and disinfection unit, a physical sterilization and disinfection device, an air filter, a hood and other auxiliary unit. Different combinations of the units of the device can achieve two work states, the positive-pressure work state andthe negative-pressure work state. When the device is in the positive-pressure work state, the hood is full of sterilized and disinfected air, the pressure is higher than environment pressure, and thedevice is suitable for healthy personnel working in environments where people are likely to be infected. When the device is in the negative-pressure state, the internal pressure of the hood is lowerthan the environment pressure, air exhaled by users is exhausted into the environment after being sterilized and disinfected, and the device is suitable for being used by suspected infected patients or diagnosed infectious victims. According to the device capable of reducing the concentrations of bacterial viruses in the local environment through direct sterilization and disinfection, bacterial viruses are eliminated from the source and are killed before being diffused, healthy personnel who have to work in the environment are protected, and the patient recovery process is promoted.

The utility model relates to an air-entraining type positive pressure hood device for protecting novel coronaviruses. According to the utility model, the totally-enclosed air supply hood is adopted toenclose the whole head, so that the propagation path is thoroughly cut off, and viruses can enter seamlessly. And viruses can be slack without wearing a mask. The survival time of the coronavirus inthe air is short; aerial air flow, sunlight irradiation and other reasons, viruses in the air are extremely rare; air is introduced from the air by using an air floating filter or a rigid air inlet pipe, fresh air far away from virus pollution is collected by using an air delivery pump, then filtered clean air is delivered to each branch, and one or more long air delivery hoses with air buoys aredistributed to each branch as required to lead to a hood for air supply, so that a fresh and clean air source is guaranteed. The long flexible air pipe with the buoy can realize that the pipeline is suspended and moves in a pipe length range along with people, so that the defects of easiness in abrasion, treading and the like caused by floor mopping movement of the pipeline are avoided, and the air supply along with the people is realized.
