OXYGEN ENRICHMENT MACHINE

摘要

PROBLEM TO BE SOLVED: To provide an oxygen enrichment machine which can gain the flow quantity of oxygen-enriched air even using a means with large air passage resistance such as an oxygen enrichment membrane or the like as an oxygen enrichment means. SOLUTION: The oxygen enrichment machine includes the oxygen enrichment means 2 disposed in a main body and a suction means 10 to suck the oxygen-enriched air from the oxygen enrichment means 2, wherein the above suction means 10 is constituted with a bellows pump and the flow quantity of the oxygen-enriched air can be gained by the intensity of the pressure produced by the bellows pump operation even when the oxygen enrichment means 2 with high air passage resistance is used.
