Abstract

The invention discloses a molecular sieve tank replacement structure of a portable oxygen generator, the molecular sieve tank replacement structure comprises an oxygen generator body and a sieve towermodule, the sieve tower module is provided with a clamping groove, and the bottom of the oxygen generator body is provided with a buckle structure which is matched with the clamping groove and used for clamping the sieve tower module. The oxygen generator body and the sieve tower module are detachably connected through a buckle structure and the clamping groove, two quick-release connectors are arranged on an air outlet nozzle of the oxygen generator body, a first air inlet pipe and a second air inlet pipe which are matched with the quick-release connectors are arranged on the sieve tower module, and an oxygen outlet nozzle is arranged between the first air inlet pipe and the second air inlet pipe; according to the molecular sieve tank replacement structure of the portable oxygen generator, a sieve tank is regarded as a semi-disposable article, so that the sieve tank can be replaced at any time instead of being protected or excessively designed, and the service life of equipment required by the whole system is achieved.

Description

technical field [0001] The invention relates to a molecular sieve tank replacement structure for a portable oxygen generator. Background technique [0002] The portable oxygen concentrator adopts physical pressure swing adsorption technology. Its principle of oxygen production is mainly to make the oxygen and nitrogen in the air pass through the molecular sieve through the air compressor, and use the difference in the adsorption capacity of the molecular sieve to the nitrogen and oxygen in the air to realize nitrogen. And the separation of oxygen, so as to obtain a continuous high concentration of oxygen. [0003] When the portable oxygen concentrator is not running, especially if it is running for a long time, there will be a strong diffusion driving force for any impurity adsorbed in the gas phase of the desiccant, adsorbent void space at the feed end of the pretreatment layer or bed. If the concentrator is not sealed to the outside atmosphere by a vent valve, contaminant...
