Nitrogen-oxygen separation device and corresponding oxygenerator

Abstract

The invention provides a nitrogen-oxygen separation device and a corresponding oxygenerator. The nitrogen-oxygen separation device comprises a gas intake module, a separation module and an oxygen output module; the gas intake module comprises a sealing cover, a switching rotation sliding block and a drive motor; the separation module comprises at least two molecular sieve assemblies, a molecular sieve front cover and a molecular sieve back cover; the oxygen output module comprises a sealing element and a gas outlet element. The invention also provides the oxygenerator. Due to the arrangement of the gas intake module in the nitrogen-oxygen separation device and the corresponding oxygenerator, the nitrogen-oxygen separation device has the advantages of simple structure, small size and low manufacture cost; and at the same time, due to the arrangement of the gas intake module, the nitrogen-oxygen separation device has good air tightness and high oxygen generating efficiency.

Description

technical field [0001] The invention relates to the field of oxygen generators, more specifically, to a nitrogen and oxygen separation device and a corresponding oxygen generator. Background technique [0002] With the development of science and technology, equipment for producing oxygen (such as oxygen generators with oxygen separation devices, etc.) At room temperature, the air is directly compressed and distributed to the molecular sieve alternately, and the nitrogen and oxygen are separated through the process of pressurization and decompression. At present, the assembly process of oxygen concentrators sold on the market is relatively complicated and there are too many internal trachea connection interfaces, resulting in the defects of large volume, low oxygen production efficiency, poor airtightness and high production cost in existing oxygen concentrators . [0003] Therefore, it is necessary to provide a nitrogen and oxygen separation device and a corresponding oxyg...
