Description

Technical Field

[0001] The utility model belongs to the technical field of adsorption tanks, in particular to a highly sealed aluminum alloy adsorption tank for an oxygen concentrator. Background Art

[0002] The oxygen concentrator adsorption tank is a key component in the oxygen concentrator, also known as the oxygen adsorbent tank or adsorbent column. The oxygen concentrator provides a pure oxygen supply by adsorbing non-oxygen components such as nitrogen in the air. The internal connection between the adsorption tank and the oxygen concentrator needs to be sealed to prevent leakage of internal oxygen. When using the adsorption tank, a highly sealed oxygen concentrator adsorption tank is required.

[0003] The upper cover and the tank body of the existing oxygen concentrator adsorption tank are mostly connected by threads, and a single sealing ring is provided between the upper cover and the tank body to seal and prevent leakage of the produced oxygen. However, multiple sets of screws are required to fix the upper cover and the tank body, and the installation process is relatively cumbersome. The sealing effect of a single sealing ring is poor. Therefore, a highly sealed aluminum alloy adsorption tank for an oxygen concentrator is proposed. Summary of the Invention
