The invention discloses a device for storing an escape face mask used in an emergency such as fires or harmful gas leakage to solve the problems that the face mask is hard to take in an emergency and the face mask is taken away easily when arranged in public places to cause loss. According to the technical scheme, the escape face mask is stored in a face mask box, and a face mask box cover plate is closed and effectively locked at ordinary times to prevent the face mask from being taken away; the face mask box is in the working state after being electrified, a fire detection and electronic control device detects the surrounding environment in real time, and the face mask box cover plate pops up instantly to enable the escape face mask to be ejected and an audible and visual alarm is given once it is detected that a fire occurs or harmful gas leaks. Due to the fact that the escape face mask is ejected out of the box and the audible and visual alarm is given to indicate the position to people, time for people to take and wear the face mask is shortened greatly; furthermore, the extra function of indicating usage is realized, so that precious time is provided for escape to the maximum extent.
