Household oxygen generators, there are many kinds of household oxygen generators on the market. Due to the different principles of oxygen production, the use characteristics of each household oxygen generator are also different. The oxygen-making principle of domestic oxygen-making machine is as follows: molecular sieve principle; Principle of polymer oxygen-enriched membrane; Principle of electrolytic water; Principle of oxygen production by chemical reaction. Molecular sieve oxygen generator is the only mature oxygen generator with international and national standards. Household oxygen generator is easy to use and portable, which is suitable for the majority of medical staff. Vehicle-mounted household dual-purpose model is not only suitable for family use, but also can be used in the car by using automobile power supply. Oxygen is a colorless and odorless gas, which is an important substance for human beings and other animals and plants to survive. Without oxygen, nature will be lifeless and lifeless. It is as important as water. A wide range of uses, all walks of life are inseparable from oxygen, including medical care, beauty. Now the standard of living is getting better and better. Everyone knows how to keep healthy. It's almost Spring Festival. Buy an oxygen generator for your family and care for their health. Now that living conditions are good, we should pay more attention to health care, such as buying an oxygen generator at home to make the whole family healthy. In order to improve the quality of life of pneumoconiosis and other workers with work-related injuries, such as impaired lung function, dyspnea and long-term oxygen inhalation, Beijing has included a 3-liter household oxygen generator in the scope of auxiliary appliances for workers with work-related injuries in Beijing. The working principle of domestic oxygen generator: adopting molecular sieve physical adsorption and desorption technology. The molecular sieve is filled in the oxygen generator, which can adsorb nitrogen in the air when pressurized, and the remaining unadsorbed oxygen is collected and purified into high-purity oxygen. When the molecular sieve depressurizes, it discharges the adsorbed nitrogen back to the ambient air, and can adsorb nitrogen and generate oxygen when it is pressurized next time. The whole process is a periodic dynamic cycle process and does not consume molecular sieve.
