Coronavirus prevention and control mask

Abstract

The invention discloses a fresh air healthy atmosphere coronavirus prevention and control mask. The mask is composed of a positive pressure type air input device, a nanofiber filtering device, a maskbody and an air disinfection device, wherein the mask body is composed of a mask frame, a transparent face window, an air inlet channel, an air outlet channel, a sealing rubber strip and a wearing elastic band; the mask frame is in an oval shape similar to the face shape of the human body; the transparent face window is in an outward convex shape; the outward convex size can envelope the face organ; the transparent face window is mounted in front of the mask frame; the sealing rubber strip is mounted behind the mask frame; and the transparent face window and the mask frame form a closed cavitywith the human face through the sealing rubber strip. The fresh air healthy atmosphere coronavirus prevention and control mask can comprehensively protect the mouth, nose and eyes of the face of thehuman body, filtered positive pressure type air is input through the air inlet channel to ensure inhaled air needed by the human body, the exhaled air is discharged through an exhalation channel and enters the disinfection device to kill harmful viruses and then is discharged into the air, and cross infection to surrounding people can be eliminated.
