In the embodiment, the gas distribution valve 3 is directly or indirectly communicated with the molecular sieve cylinder 4 of the oxygen generator, and as a preferred embodiment of the embodiment, the embodiment further comprises a first integrated docking support 2, and the gas distribution valve 3 is communicated with the molecular sieve cylinder 4 of the oxygen generator through the first integrated docking support 2 to realize the indirect communication described above.

[0054] Further, please refer to Figure 6 and Figure 7The first integrated docking support 2 is arranged on the first support section 11. The first integrated docking support 2 is provided with a first air inlet joint 21 and a first oxygen joint 22. The first air inlet joint 21 is provided with a first air inlet adapter 211 and a first air inlet docking port 212 which are in communication.

[0056] The molecular sieve of the oxygen generator is a component of common knowledge in the art. The present embodiment aims to improve the structure of the air inlet and oxygen outlet. As a preferred embodiment of the present embodiment, the oxygen generator molecular sieve cylinder 4 comprises an upper sieve cover 41, a lower sieve base 42, a second integrated docking support 44 and two molecular sieve cylinder bodies 43. The difference between the present embodiment and the prior art lies in that the air inlet 312 and the oxygen outlet joint 442 of the two molecular sieve cylinder bodies 43 are integrated on the top, which facilitates the docking with the first integrated docking support 2. Specifically, the second integrated docking support 44 is arranged on the upper sieve cover 41. The air inlet joints 441 of the two molecular sieve cylinders and the oxygen outlet joint 442 of one molecular sieve are integrally arranged on the second integrated docking support 44.

Further, in order to form stability in the horizontal direction and prevent the first integrated docking support 2 and the molecular sieve from being affected by external forces in a non-docking direction, a guide wedge surface 110 is formed on the first bracket section 11 facing the upper sieve cover 41. Correspondingly, a guide matching surface 450 is formed on the upper sieve cover 41 facing the guide wedge surface 110.

[0059] Based on the filtering properties of the molecular sieve cylinder body 43, in this embodiment, the molecular sieve cylinder body 43 has gas inlet at the upper end and oxygen outlet at the lower end. In order to realize integrated arrangement for gas exchange with the oxygen generator main body 5, the oxygen outlet connector 442 of the molecular sieve is connected to the oxygen supply channel of the molecular sieve cylinder body 43 through a gas guide extension pipe 45, and the guide matching surface 450 is implemented as the side surface of the gas guide extension pipe 45.

[0060] Please refer to Figure 8 and Figure 9 , the first oxygen outlet adapter 221 of the first integrated docking support 2 supplies oxygen, which generally enters the oxygen storage tank 52 of the oxygen generator main body 5 through a flow control meter and a concentration test meter. Therefore, an oxygen flow control valve 53 is further arranged on the second bracket section 12 near the connecting section 13, which is connected to the first oxygen outlet adapter 221.

[0061] As mentioned above, the oxygen generator main body 5 also has an air compression assembly 51 and an oxygen storage tank 52, in order to facilitate the installation of the two, a first mounting port 121 for fan installation and a second mounting port 122 for oxygen storage tank 52 installation are further arranged on the second bracket section 12.

[0062] As a preferred embodiment of the present embodiment, the molecular sieve further has a molecular sieve shell 46, which is semi-enclosed in the molecular sieve, and the molecular sieve cylinder body 43 is screw-fitted and installed with the oxygen generator main body 5. The screw installation method and position belong to the conventional installation structure, which will not be described here.

[0063] It should be noted that although the present embodiment does not specifically illustrate the hose for connecting the various components, this connection method is common knowledge, and those skilled in the art will necessarily know it when they know the connection position. For example, the connection between the gas distribution valve 3 and the air compression assembly, the gas supply end of the air compression assembly 51 is connected to the gas inlet 312 of the gas distribution valve 3 through a hose.
