Non-contact face close-range air supply and exhaust device capable of preventing novel coronavirus pneumonia virus propagation

Abstract

The invention relates to a non-contact face close-range air supply and exhaust device capable of preventing novel coronavirus pneumonia virus propagation. The non-contact face close-range air supply and exhaust device comprises a head ring, a temperature sensing probe, an air guide cylinder, an upper baffle and a connector. A connecting rod is arranged at the top end of the head ring; the temperature sensing probe is arranged at the outer end of the connecting rod; a cavity is formed in the air guide cylinder, an airflow through hole is formed in the inner ring, and the airflow through hole iscommunicated with the cavity; rotating shafts are arranged inside the two ends of the air guide cylinder; the rotating shafts are rotationally connected with the head ring; a joint is arranged on oneside of the head ring, an opening is formed in the outer side of the joint, and the opening is communicated with the cavity; the upper baffle and a lower baffle are arranged in the middle section ofthe air guide cylinder; a rotating groove is formed in the connector, and the connector is rotationally connected with the joint; an air guide pipe is arranged at the lower end of the connector; airflow in the air guide pipe can enter and exit from the airflow through hole through the connector, the joint and the cavity; and the air guide cylinder can rotate along center lines A of the rotating shafts. The non-contact face close-range air supply and exhaust device can provide guarantee for public to block superstrong virus propagation in a superstrong virus prevalence period.

Description

technical field [0001] The invention relates to the field of blocking virus transmission, in particular to a short-distance air supply and exhaust device that does not touch the face to prevent the spread of the new crown pneumonia virus. Background technique [0002] When people are in the same air environment as potential patients with new coronary pneumonia, the virus can be transmitted through suspended particles in the air as a carrier. The virus can pollute the nearby air through the air, especially the virus-carrying saliva can mix with the air to form an aerosol floating in the air for a long time, the medical staff in the hospital can protect themselves by wearing protective clothing, and ordinary people even wear masks in public It is also difficult to avoid being infected. [0003] COVID-19 is airborne, and when a sick person breathes, talks, coughs or sneezes, it produces tiny droplets that infect those around him. Infected people may also be infected by aeroso...
