摘要（英）：

A device for purifying a gas in an enclosed space includes: a container containing a target gas with a content of α, content of the target gas in air being β ranging from 0% to 1%, and α>β; a sensor configured to detect the content of the target gas in the enclosed space; a first valve arranged in a gas path between the container and a first purification unit; the first purification unit with an output end in communication with the enclosed space; a second valve with an input end in communication with the air and an output end in communication with a second purification unit; the second purification unit with an output end in communication with the enclosed space; and a gas path switch module with an input end in communication with the enclosed space. Also, a method for purifying gas in an enclosed space is disclosed.
