Oxygen enriching devices

Abstract

An oxygen enrichment apparatus includes an oxygen enriching unit for generating oxygen-enriched air and a discharge unit for discharging the oxygen-enriched air transferred from the suction unit. The oxygen-enriched air generated by the oxygen enriching unit has an oxygen concentration ranging from about 25% to 35%. The apparatus also includes a suction unit for suctioning the oxygen-enriched air from the oxygen enriching unit and a control unit for controlling the operation of the suction unit. The main body is provided with a display unit for indicating a state that the oxygen-enriched air is being discharged out by the discharge unit. The oxygen enriching unit has at least one oxygen enriching membrane for generating the oxygen-enriched air and a condensed water treating unit is installed at an air passage for guiding the oxygen-enriched air from the oxygen enriching unit to the discharge unit via the suction unit.

Description

technical field [0001] The present invention relates to an oxygen enrichment device for providing oxygen enriched (ie, increased oxygen concentration) air to a user. Background technique [0002] In general, oxygen enrichment devices have been devices used in the medical field in the past. Since it is a device for treatment, it is necessary to control the oxygen concentration with high precision, and as a result, the device is expensive and bulky. Therefore, it is not yet a device that can be used by ordinary users if they want to use it. [0003] Therefore, Japanese Patent Laid-Open Publication No. Hei 10-234836 proposes an oxygen enricher that can be used freely by ordinary users. Specifically, the structure of this oxygen-enrichment machine is that an oxygen-enrichment film is arranged in the main body, and an air pump is used to suck out the oxygen-enriched air passing through the above-mentioned oxygen-enrichment film, and supply the sucked oxygen-enriched air to the ...

AI Technical Summary

Problems solved by technology

As a result, it is difficult to expect a significant increase in the oxygen concentration inhaled by the human body.

[0006] In addition, in the case of using an oxygen-enriched membrane, since the oxygen-enriched membrane not only makes it easy for oxygen to pass through, but also makes it easy for moisture in the air to pass through, the moisture in the oxygen-enriched air will condense, and the condensation water and the oxygen-enriched air will If it is sprayed together, the user will feel uncomfortable, and there are also problems such as the need for maintenance when using zeolite
