1. Oxygen generator market background:

In recent years, with the improvement of people's living standards, people pay more attention to their own health. Oxygen therapy and oxygen health care as a new technology to enhance physical fitness and prevent diseases are gradually being accepted and promoted. Home oxygen generator this emerging industry also will quietly rise, and showed a strong growth trend.

2Oxygen generator market prospects:

At present, household oxygen generators have been widely used in cardiovascular diseases, cerebrovascular diseases, respiratory diseases, altitude sickness and altitude sickness, senile diseases, children's respiratory tract infections, sleep hypoxemia, gas poisoning and hypoxia and other diseases. Treatment; suitable for families, health stations, health centers, hospitals, sanatoriums, dry rest centers, beauty salons, fitness centers, bars, oxygen bars, hotels, plateau outposts, sports training centers and other places; it is a family companion for students, white-collar workers, athletes, the elderly, pregnant women, fetuses, etc. for mental and physical recovery, adjuvant treatment and physical health care.

3Working principle of oxygen generator:

Pressure swing adsorption is the use of different pressure adsorbents for oxygen and nitrogen in the air adsorption capacity and selectivity of nitrogen and oxygen separation. The oxygen concentration produced by the pressure swing adsorption oxygen generator can reach95%And the concentration can be controlled by adjusting the flow rate, even in areas with thin plateau atmosphere, high concentration oxygen supply can be achieved.

4Working flow of oxygen generator:

Medical oxygen generator with pressure swing adsorption(PSA)Based on the technology, a new type of equipment for extracting oxygen from the air uses molecular sieve physical adsorption and desorption technology to fill the molecular sieve in the oxygen generator. When pressurized, the nitrogen in the air can be adsorbed, and the remaining unabsorbed oxygen is collected. After purification, it becomes high-purity oxygen. The specific working process is that after the compressed air is purified by the air purification dryer, it enters the adsorption tower through the switching valve. In the adsorption tower, nitrogen is adsorbed by the molecular sieve, oxygen is accumulated at the top of the adsorption tower and enters the oxygen storage tank, and then filtered by the odor removal, dust removal filter and sterilization filter to obtain qualified medical oxygen.

5Technical parameters of oxygen generator:

According to the analysis of statistical materials, domestic household oxygen generator manufacturers mostly adopt pressure swing adsorption oxygen generation. Different manufacturers have carried out the design, development and production of different specifications and models according to market demand. According to the oxygen production is divided2L/min、3L/min、4L/minand5L/minOxygen generator. The output pressure range is generally0.04~0.06MPa(relative pressure), the oxygen concentration is greater90%. However, due to the different technical advantages of various oxygen generator manufacturers, the volume, weight, energy consumption and noise of their products are also quite different, especially when the household oxygen generator is used for oxygen inhalation of patients, the noise is required to be reduced as much as possible so as not to disturb the sleep of patients.

Here, to recommend you a detection of oxygen sensorSO-E2-960This sensor is Austria.SensorLimiting current oxygen sensor specially developed for detecting oxygen.

1. oxygen sensorSO-E2-960Working principle

Because the carrier of the current in the zirconia electrolyte is oxygen ions, when a voltage is applied to the zirconia cell, oxygen is drawn through the zirconia disk to the anode. If a perforated cover is added to the cell cathode, the rate of oxygen flow to the cathode is limited. Limited by this rate, the current in the cell will reach saturation as the applied voltage is gradually increased. This saturation current is called the limiting current and is proportional to the oxygen concentration in the ambient environment.
