PROBLEM TO BE SOLVED: To provide an inexpensive oxygen enricher by simplifying constitution of the whole product. SOLUTION: The oxygen enricher is provided with: a suction means 3 for generating oxygen-enriched air through an oxygen enriching means 2; an energizing means 8 for energizing the suction means 3; and a temperature detection means 12 for detecting the temperature of the suction means raised with the operation of the suction means 3. When the temperature detected by the temperature detection means 12 reaches a prescribed setting operation temperature, energizing to the suction means 3 by the energizing means 8 is stopped. A distance between the temperature detection means 12 and the suction means 3 is variable. For example, when the distance between the temperature detection means 12 and the suction means 3 is varied, a time for a temperature which is raised from the start of operation of the suction means detected by the temperature detection means 12 to reach the prescribed setting operation temperature is varied, that is, the operation time of a main body 1 can be varied. Thus, the oxygen enricher where the operation time can be set without an expensive timer means is provided inexpensively. COPYRIGHT: (C)2007,JPO&INPIT
