Description

Technical Field

[0001] The utility model relates to the field of oxygen concentrator equipment, in particular to a novel portable oxygen concentrator. Background Art

[0002] An oxygen concentrator is a machine used to produce oxygen. It uses air separation technology to separate nitrogen and other impurities in the air through physical and chemical methods to provide high-concentration pure oxygen.

[0003] The working principle of the oxygen concentrator mainly includes the following steps: First, the oxygen concentrator uses a compressor to compress the air into high-pressure gas, usually 2 to 3 times the atmospheric pressure; then, the high-pressure gas enters the condenser and is cooled. During this process, most of the water vapor and liquid impurities will condense into liquid water and be removed; then, the cooled gas enters the adsorbent bed, usually using a substance called a molecular sieve, which selectively adsorbs nitrogen and other impurities to separate pure oxygen; finally, the pure oxygen is released and transported through a pipeline to where the user needs it, such as an oxygen mask or oxygen cylinder;

[0004] A portable oxygen concentrator is generally carried in a shoulder bag when in use. When the oxygen concentrator is placed inside the shoulder bag, part of the oxygen concentrator is wrapped by the outer side of the shoulder bag, which affects the user's ability to press the button on the side of the oxygen concentrator, making it inconvenient for the user to adjust the output power of the oxygen concentrator at any time. Therefore, a device is urgently needed to solve the above problem. Utility Model Content
