Description

technical field [0001] The invention relates to the technical field of oxygen generators, in particular to an oxygen generator solenoid valve control structure and a control system thereof. Background technique [0002] Oxygen concentrator is a kind of machine for producing oxygen. Its principle is to use air separation technology to first compress the air with high density and then use the difference in the condensation point of each component in the air to separate the gas and liquid at a certain temperature. , obtained by further rectification. At present, the system solenoid valves of small medical oxygen generators, the working hours of molecular sieve tower A and molecular sieve tower B are controlled by preset time, that is, by setting molecular sieve tower A and molecular sieve tower B in the MCU. The single tower intake time and the common intake time of the molecular sieve tower B are used to control the working sequence of the solenoid valve of the system to contr...

Problems solved by technology

[0003] However, the oxygen concentrator controlled by the above method is greatly affected by the altitude of the operating environment, because at different altitudes, the gas output of the air compressor in the oxygen concentrator is different in the same time period, which leads to the molecular sieve in the oxygen concentrator system. The conversion of adsorption and desorption is carried out under the optimal adsorption pressure, which will affect the working efficiency of the whole oxygen production system. Control System
