PROTECTIVE MASK FOR RESPIRATORY ORGANS

WIPO Patent Application WO/2021/080063

A1

The present invention relates to a protective mask for respiratory organs, wherein: an exhaled breath discharging member and an inhaled breath suctioning member are formed on a body of the protective mask; cold and dry air is suctioned through the inhaled breath suctioning member into a space (a preheating chamber) formed by spacing a mask fabric apart from a person's body (the skin), and the heat generation and perspiration phenomena of the person's body or a heat-generating body and humidifying device equivalent thereto inside the preheating chamber raise the temperature and humidity of the suctioned air; and the air having the mitigated properties is inhaled by a user after moving to a space (hereinafter, an air room) formed in front of the mouth/nose regions through a path connecting the air room and the preheating chamber. Therefore, the present invention has the significant effects of: preventing/mitigating deterioration in exercise ability and immunity or respiratory diseases; ensuring that exhaled breath is discharged to the outside of the mask through a one-way air outlet of the exhaled breath discharging member, thereby preventing the exhaled breath from back-flowing to the preheating chamber and mixing with the suctioned fresh air; and preventing fogging of eye-glasses or goggles.
