Description
Technical Field
The invention relates to the field of virus propagation blocking, in particular to an indoor temperature-controlled short-distance air supply and exhaust device for preventing new crown pneumonia virus propagation.
Background
When people are in the same space environment as the potential new coronary pneumonia patients, viruses can be transmitted by using suspended particles in the air as carriers. Viruses can pollute nearby air through the air, and particularly virus-carrying saliva can be mixed with the air to form aerosol which floats in the air for a long time.
The new corolla pneumovirus is airborne and produces fine droplets to infect people nearby when the patient breathes, speaks, coughs or sneezes. The infected person may be infected with aerosol formed by fine droplets and gas suspended in the air at home, work, store, vehicle or medical place, and even if wearing the mask, the infected person may inhale the air with virus from the aerosol with virus in the gap between the face and the mask (especially in the valley between the bridge of the nose and the lower eyelid) because the mask is not completely attached to the face.
When patients suddenly increase and medical settings and equipment are insufficient, people often can only stay at home and isolated. But isolating them at home is entirely likely to infect their own family. The prior art does not have a device capable of providing fresh air at a short distance for healthy people, and the outbreak of family type and gathering type infection is difficult to avoid.
At present, asymptomatic new coronary pneumonia appears, and the prevention and control difficulty is higher and higher. However, no device capable of directly providing fresh air to healthy people in a short distance in an indoor space is available in the market.
