Problems solved by technology

[0002] In daily life and medical fields, masks are more and more widely used. Traditional masks cover the mouth and nose when in use, although they block external harmful substances, etc., but the exhaust gas discharged by the wearer cannot be quickly eliminated. In addition, when a cold occurs, the high-temperature breathing environment intensifies the water vapor content in the atmosphere of the mouth and nose, resulting in dry mouth and nose, poor comfort, which is not conducive to the health of the wearer. Add a mask exhalation valve to the mask can solve this problem very well
