[0039] Please refer to further information. Figure 7 , Figure 7 This is a seventh structural schematic diagram of an embodiment of the molecular sieve end cap provided in this application. Figure 7 As shown, the muffler 120 is provided with an air inlet 121 and an air outlet 122. The air inlet 121 and the air outlet 122 are respectively connected to the muffler cavity 12. The air inlet 121 is also connected to the third air passage 103, and the air outlet 122 is also connected to the outside of the muffler 120 or the muffler cavity 12.

[0042] In one embodiment, the silencing unit 120 further includes a silencing baffle 123, which can be one or more. In this embodiment, the silencing baffle 123 is disposed on the silencing housing 1211.

The air inlet 121 connects to the first chamber, and the air outlet 122 connects to the second chamber.
[0043] The sound-absorbing baffle 123 is provided with an opening 1231, which connects the first chamber and the second chamber respectively, so that the first chamber and the second chamber can form an airflow communication.
[0044] In a preferred embodiment, the silencing baffle 123 is disposed along the bottom wall perpendicular to the silencing housing 1211. The opening 1231 is disposed on the side away from the air inlet 121, thereby increasing the path of the nitrogen exhaust airflow and improving the silencing effect. Specifically, the opening 1231 is disposed on the side of the silencing baffle 123 away from the bottom wall of the silencing housing 1211, that is, on the side near the silencing cover 1212, forming an airflow channel connecting the first and second cavities with the silencing cover 1212. In a preferred embodiment, the opening 1231 is disposed on the side of the silencing baffle 123 away from the air inlet and away from the bottom plate, meaning the upper half of the silencing baffle 123 on the side away from the air inlet has a window. In other embodiments, the opening 1231 may only be disposed on the side away from the air inlet, meaning the silencing baffle 123 has a window between the cover and the bottom plate, rather than a partial window.
[0045] The molecular sieve end cap 10 is also equipped with an oxygen outlet 140 (see [link]). Figure 1 An oxygen storage tank is disposed between the first adsorption tower tank 111 and the second adsorption tower tank 112 for outputting oxygen.

The molecular sieve end cap 10 is connected to the first adsorption tower 81 and the second adsorption tower 82, respectively. Specifically, the molecular sieve end cap 10 is disposed on the same end of the first adsorption tower 81 and the second adsorption tower 82, and is sealed to the first adsorption tower 81 and the second adsorption tower 82.
[0048] The valve body 20 is connected to the molecular sieve end cap 10 of the molecular sieve. Specifically, the valve body 20 is installed in the valve body groove 113 of the molecular sieve end cap 10 (see [link]). Figure 3 ).
[0049] The beneficial effects of this application are as follows: By setting a first gas channel communicating with the first adsorption tower groove, a second gas channel communicating with the second adsorption tower groove, and a third gas channel communicating with the silencer cavity inside the molecular sieve end cap, the air intake and exhaust of the molecular sieve can be controlled, improving the integration of the molecular sieve end cap and avoiding the need for additional gas path connections. Furthermore, integrating the gas paths connecting the adsorption towers inside the molecular sieve end cap effectively reduces the number of components, thereby reducing the number of connections between components, reducing leakage points, improving stability, and simplifying the overall structure of the molecular sieve end cap, thus effectively reducing processing costs, material costs, and assembly costs. In addition, the molecular sieve end cap is also provided with a valve body groove; by installing the valve body groove on the molecular sieve end cap, the total space occupied by the valve body and the molecular sieve can be effectively reduced.
