[0003] 1. Oxygen production equipment that uses chemical agents as raw materials. Although the price of this oxygen production equipment is relatively cheap, since it is chemical oxygen production, the oxygen produced will carry some other impurity gases, which may have some side effects and is not suitable for long-term use.

[0004] 2. Oxygen-enriched membrane oxygen generator. This oxygen-generating equipment utilizes a polymer oxygen-enriched membrane to allow oxygen molecules in the air to pass through first, thereby achieving physical concentration of oxygen. However, due to the low level of current oxygen-enriched membrane technology, the oxygen concentration produced by this oxygen-generating equipment cannot reach the level of physical therapy.

[0005] 3. Molecular sieve oxygen generator. This oxygen generator separates oxygen from the air through molecular sieves and compressors. However, its oxygen production effect is determined by the quality of the molecular sieves and compressors. The complex process makes it difficult to control quality. In addition, this type of oxygen generator is large in size and cannot be used portablely.

[0006] 4. Electrolytic oxygen generator. This electrolytic oxygen production technology mainly refers to the technology of using water electrolysis to produce hydrogen and oxygen. Compared with the other three types of equipment, this oxygen production equipment has clean raw materials and will not produce other harmful by-products. The oxygen concentration produced can also reach the therapeutic concentration required by the human body.
