The oxygen generator mainly uses molecular sieve physical adsorption and desorption technology. Adsorption, the remaining unabsorbed oxygen is collected, and it becomes high-purity oxygen after purification treatment, but the existing oxygen generators are relatively small in volume, resulting in a low amount of oxygen obtained during oxygen production , the power consumption is too large, and the existing oxygen generator lacks heat insulation and refrigeration equipment. As a result, after the air enters, the oxygen generator is often affected by the external temperature, so that when the air is compressed and separated, the separation effect is low, resulting in the production of oxygen. The purity is low. In addition, the existing oxygen concentrator only has a single adsorption and filtration treatment equipment inside, lacks primary filtration and fine filtration, so that the purity and quality of oxygen after production is low, and the lack of mobile function makes the oxygen concentrator move. , It becomes troublesome when transporting.
