Description

Technical Field

[0001] The utility model relates to the technical field of air control equipment, in particular to a diffusion oxygen generator and a system. Background Art

[0002] Life cannot do without oxygen, and the health and therapeutic effects of oxygen inhalation have been widely recognized and applied by the medical community. Small molecular sieve oxygen generators using PSA pressure swing adsorption have entered tens of millions of households as medical devices and home health care equipment. Small molecular sieve oxygen generators can extract oxygen with a concentration of about 93% from the air by simply turning on the power, and provide it to users at a flow rate of 1-10L / minute, which can improve the body's blood oxygen saturation, improve tissue hypoxia, promote the body's metabolic function, and maintain the body's life activities. It is an important treatment method. Long-term use of oxygen therapy helps to reduce hypoxemia, relieve pulmonary hypertension, relieve bronchospasm, improve the patient's physical condition, improve sleep and brain function, improve exercise endurance and quality of life, improve chronic obstructive pulmonary disease, and prolong life.

[0003] The air in plateau areas is thin, and some people who have just arrived in plateau areas often suffer from altitude sickness. In order to reduce the discomfort caused by altitude sickness, people use oxygen concentrators to obtain high-oxygen concentration gas for breathing. Ordinary oxygen concentrators require wearing nasal cannulas for oxygen inhalation. Diffusion oxygen concentrators increase the oxygen concentration of indoor air, allowing people to get rid of the restrictions of nasal cannulas and breathe more freely. The main host of existing diffusion oxygen concentrators is usually installed outdoors, and outdoor air collection and outdoor oxygen production are used to diffusely supply indoor oxygen. The indoor oxygen concentration is set by oxygen sensors, generally at 22-25%, to control the start or shutdown of the diffusion oxygen concentrator.

[0004] The existing diffuse oxygen generators have the following defects: if the airtightness of the oxygen-demanding space is poor, the oxygen concentration of the diffuse oxygen generator increases very slowly when supplying oxygen to the oxygen-demanding space, and oxygen can easily escape, resulting in large oxygen losses and high energy consumption, leading to increased oxygen costs. If the airtightness of the oxygen-demanding space is good, the diffuse oxygen generator supplies oxygen to the oxygen-demanding space, and the oxygen concentration increases quickly. In theory, the oxygen concentration of the oxygen-demanding space is close to the oxygen concentration output by the oxygen generator. There are safety hazards in controlling the startup or shutdown of the machine by only setting the upper and lower values ​​of the oxygen sensor, because the life of the chemical oxygen sensor is 1 year, and the accuracy of the oxygen sensor will decrease after natural attenuation. When the oxygen concentration in the oxygen-demanding space exceeds 35%, it will not alarm and shut down, which may cause harm due to excessive oxygen concentration.

[0005] In addition, the existing diffuse oxygen generator collects gas and produces oxygen outside the oxygen-demanding space, and transports oxygen to the oxygen-demanding space, making the oxygen-demanding space in a slightly positive pressure state. People often open the door when entering and exiting, and oxygen is easy to escape. The carbon dioxide exhaled by people in the oxygen-demanding space cannot be effectively discharged outdoors, resulting in a high carbon dioxide concentration. Utility Model Content
