Description

Technical Field

[0001] The utility model relates to the technical field of oxygen generators, and more specifically to an oxygen generator structure with replaceable molecular sieves. Background Art

[0002] With the development of national medical and health care, people's pursuit of health has gradually improved, and more and more oxygen generators have entered thousands of households. Among them, the PSA pressure swing adsorption oxygen generator structure has many advantages such as simple structure, high cost performance, stable oxygen output, small size, etc., so the small and medium-sized PSA oxygen generator structure has become the mainstream product in the high market. It uses AC power as the power source and air as the raw material. It compresses air through an air compressor and uses molecular sieves at room temperature through pressure swing adsorption separation method (PSA method) to collect high-concentration oxygen; the molecular sieve adsorbs nitrogen and is discharged from the exhaust port, while the oxygen passes through the molecular sieve tower and is stored in the oxygen storage tank (see Figure 7 ).

[0003] Since the molecular sieve has a strong ability to absorb water, which is 10 times the ability to absorb nitrogen, and the molecular sieve pores are irreversibly filled with water molecules (500°C is required to separate the water molecules), the adsorption capacity is lost, and nitrogen and oxygen cannot be separated. The machine can only continue to collect oxygen by replacing a new molecular sieve. Even if used in a dry environment, the life of the molecular sieve is only about 8,000 hours. When the molecular sieve fails, the oxygen generator structure must be replaced with a new molecular sieve.

[0004] However, the molecular sieves in the oxygen generators currently on the market are basically not replaceable or very complicated to replace, and can only be replaced by professional maintenance personnel or the original manufacturer. Therefore, if the molecular sieve can be replaced like a water purifier and other products, the service life of the molecular sieve oxygen generator structure can be greatly improved.
