ABSTRACT:
An emergency oxygen mask includes: a respiration part worn on a user's face for supplying oxygen or discharging carbon dioxide or moisture using a pressure difference depending on respiration of the user; a carbon dioxide supply part for supplying the carbon dioxide and the moisture discharged from the respiration part through a carbon dioxide supply hole at a lower surface of the carbon dioxide supply part; an oxygen generating part engaged with an outer surface of the carbon dioxide supply part and having an upper open surface for reacting potassium dioxide in the carbon dioxide supply part with carbon dioxide or moisture to generate oxygen; an oxygen storage part for storing oxygen moved by an oxygen moving part; and filters attached to opposite sides of the oxygen moving part to remove carbon dioxide remaining in the oxygen stored in the oxygen storage part and to lower the temperature and humidity of the oxygen supplied to the respiration part.
