The operation of the oxygen enrichment device 1 in this embodiment is as follows:

the oxygen enrichment device 1 is started, and the control panel 5 controls the fan 12 and the vacuum pump 15 to start. Outdoor air is sucked in from the air inlet 111 by the fan 12, filtered by the filter assembly 2 and flows to the oxygen-enriched membrane assembly. The vacuum pump 15 is connected with the oxygen-enriched membrane assembly through a connecting pipeline 16, the inside of the oxygen-enriched membrane assembly is vacuumized, and under the condition that a pressure difference exists between the inside and the outside of the oxygen-enriched generating unit 13, oxygen molecules in air preferentially permeate the oxygen-enriched generating unit 13, and oxygen-enriched gas with the oxygen concentration being greater than that in air is formed in the oxygen-enriched membrane assembly. Nitrogen molecules in the air are blocked by the oxygen-enriched generating unit 13 to form nitrogen-enriched gas outside the oxygen-enriched generating unit 13. The oxygen-enriched gas in the oxygen-enriched membrane assembly flows out from the connection port 141 of the oxygen-enriched membrane assembly, flows into the vacuum pump 15 through the connection pipeline 16 from the gas inlet 151 of the vacuum pump 15, and is discharged from the gas outlet 152 of the vacuum pump 15. Oxygen-enriched gas discharged from a gas outlet 152 of the vacuum pump 15 enters the oxygen-enriched conveying pipeline 17 and is conveyed to the air-conditioning indoor unit, and then the air-conditioning indoor unit conveys the oxygen-enriched gas into the indoor space so as to improve the oxygen content of indoor air and provide a comfortable indoor environment for users. The nitrogen-rich gas in the oxygen-enriched device 1 flows through the vacuum pump 15, takes away heat generated by the operation of the vacuum pump 15, and is discharged to the outside through the exhaust port 18 provided on the housing 11.
