The invention relates to the technical field of medical oxygen generators, in particular to a medical oxygen generator convenient for replacing a filter element, the medical oxygen generator comprises a shell, a cover plate is mounted on the shell, a mounting block is arranged at the bottom of the cover plate, a nitrogen discharge pipe is mounted on the mounting block, a first electromagnetic valve is arranged on the nitrogen discharge pipe, and an oxygen generation mechanism and a transmission mechanism are mounted in the shell. The oxygen generation mechanism comprises an air inlet assembly and an oxygen generation assembly, the air inlet assembly is communicated with the oxygen generation assembly, the air inlet assembly is installed in the shell, the transmission mechanism comprises a fixed assembly and a rotating assembly, the fixed assembly is installed in the shell, the oxygen generation assembly is installed on the fixed assembly, the rotating assembly is installed in the shell, and the oxygen generation assembly is in transmission connection with the rotating assembly. One end of the nitrogen discharge pipe is communicated with the oxygen generation assembly, and the oxygen discharge pipe is mounted on the shell, so that the problems that the existing filter element is generally closed and is fixedly arranged in the oxygen generator, and the replacement is relatively tedious and inconvenient are solved.
Description
technical field [0001] The invention relates to the technical field of medical oxygen concentrators, in particular to a medical oxygen concentrator which is convenient for replacing filter elements. Background technique [0002] The common type of medical oxygen concentrator is pressure swing adsorption oxygen concentrator. When producing oxygen, nitrogen is adsorbed by the adsorber in the filter element of the oxygen concentrator, so that the unadsorbed oxygen is discharged, so that oxygen can be extracted from the air. When not in use, the adsorber is regenerated by discharging the nitrogen gas adsorbed by the adsorber, so that the oxygen generator can produce oxygen for a long time, which is suitable for medical institutions and families for oxygen therapy and health care. [0003] At present, after long-term use, the filter element in the oxygen generator tends to absorb more impurities and bacteria, so that the prepared oxygen contains more bacteria, which is not conven...
