Problems solved by technology

However, the current PSA oxygen concentrators require compressors and molecular sieve components, resulting in complex assembly, large overall volume, high power consumption, and inconvenient portability.
[0003] The applicant filed a patent application for a portable oxygen concentrator in 2013. The structure of the oxygen concentrator is complicated. Since the gas pipeline is arranged in the molecular seat, the molecular seat needs to be processed, and the molecular seat The volume is small, and the air filter barrel, oxygen storage tank, venting muffler, air channel, oxygen channel and venting channel are installed in the molecular seat, which is very difficult to process. In the prior art, the processing accuracy of the molecular seat is very high. It often happens that the processed cavities and channels are unqualified or directly lead to damage to the structure of the molecular base. The structure of the molecular base is complex, the processing cost is high, and the processing is difficult.
In addition, the structure of the oxygen generator is relatively complicated, the volume is large, and it is inconvenient to carry
