Abstract

The invention discloses a modular oxygen generator with adjustable oxygen generation concentration and an oxygen generation method, and relates to the technical field of oxygen generation equipment and solves the technical shortcomings that the existing oxygen generation equipment lacks intelligent management, is inconvenient to adjust and not environment-friendly and the like. The oxygen generator also comprises a control circuit for controlling each valve, a pressure sensor connected with the control circuit and used for detecting the pressure in an adsorption tank, and an oxygen concentration sensor for detecting the output oxygen concentration of a gas outlet valve. The output oxygen concentration can be changed simply by adjusting the valve values L, H and Q; if the required oxygen concentration is high, the values of H and Q are increased, and the value of L is reduced; and if the required oxygen concentration is low, the duration of the working state of one oxygen generation unit is relatively long, and the other oxygen generation unit lasts for a relatively long waiting time, thereby saving energy and protecting the environment.

Description

technical field

[0001] The invention relates to the technical field of oxygen-generating equipment, in particular to the intelligent control and convenient and adjustable structure improvement of medical oxygen-generating equipment. Background technique

[0002] At present, the pressure swing adsorption oxygen generator generally uses two molecular adsorption tanks for oxygen production, and one adsorption tank is working while the other is desorbing and aerating. Existing pressure swing adsorption oxygen generators lack intelligent control, and when the oxygen concentration needs to be adjusted, the operation is inconvenient, the adjustment accuracy is poor, and there is a lot of useless work, serious waste of power resources, and lack of environmental protection. Contents of the invention

[0003] To sum up, the purpose of the present invention is to solve the technical problems such as the lack of intelligent management, inconvenient adjustment and operation, and lack o...
