[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Refer to the instruction manual appendix Figures 1-5 This utility model provides a vehicle-mounted membrane separation oxygen generator, including an oxygen generator body. The oxygen generator body includes a variable frequency compressor 1, a filter 2, a membrane module 3, an oxygen supply pipeline 4, a silencer 5, a concentration detection system 6, and an electrical system 7. The variable frequency compressor 1, filter 2, membrane module 3, oxygen supply pipeline 4, silencer 5, concentration detection system 6, and electrical system 7 are all externally mounted in the same housing 8.

[0024] The variable frequency compressor 1 draws in air from the outside and compresses it to a certain pressure. Then, the air passes through the filter 2 to remove impurities such as dust, moisture, and oil, ensuring the purity and quality of the oxygen. The purified gas is sent into the membrane module 3, where the membrane module 3 separates and purifies the oxygen. The separated pure oxygen is further sent into the oxygen pipeline for delivery to the user. During operation, the silencer 5 reduces noise and improves user comfort. At the same time, the concentration detection system 6 monitors the oxygen concentration and flow rate to ensure that the user receives an appropriate amount of oxygen. The electrical system 7 is used to regulate the operation of the oxygen generator and monitor various oxygen parameters, thereby achieving centralized optimization and achieving an instant-on effect. This eliminates the need for air pressure storage tanks and other devices required by traditional membrane oxygen generators, reducing size and weight, and making it easy to install. This allows the oxygen generator to be widely used in locations with limited installation space.

[0025] To enhance the rigidity of the muffler 5 and reduce vibration and noise caused by gas flow, such as Figure 1 , 2 As shown in Figures 4 and 5, a positioning component for enhancing the stability of the muffler 5 is installed on the front end of the housing 8 near the muffler 5. The positioning component includes a fixed shell 9 and a movable shell 10.

Sound-absorbing cotton 11 is installed on the side of the fixed shell 9 and the movable shell 10 that are close to each other. Both sound-absorbing cotton 11 are fitted on the outside of the muffler 5. The fixed shell 9 and the movable shell 10 support and fix the outside of the muffler 5, thereby ensuring the stability of the muffler 5 and reducing vibration. At the same time, the sound-absorbing cotton 11 absorbs noise, thereby improving the stability and sound absorption effect of the muffler 5 and ensuring the performance of the muffler 5.

[0026] To facilitate the disassembly and maintenance of the positioning components, such as Figure 4 and 5 As shown, a fixing bracket 12 is installed on the rear side of the fixing shell 9. Two fixing bolts 13 are provided on the side of the fixing bracket 12 away from the shell 8. The fixing bolts 13 pass through the fixing bracket 12 and extend into the interior of the shell 8. The fixing bolts 13 are threadedly connected to the shell 8. By connecting the fixing bolts 13 on the fixing bracket 12 to the shell 8, the positioning component can be installed outside the shell 8 to ensure the stability of the positioning component. At the same time, the detachable fixing bolts 13 allow the operator to remove the fixing bolts 13 to remove the positioning component for maintenance.

[0027] To ensure a tight connection between the fixed shell 9 and the movable shell 10, such as Figure 4 and 5As shown, a fixing plate 14 is installed at both the top and bottom of the fixed shell 9. Two fixing grooves 15 are formed on the side of the fixing plate 14 closest to the movable shell 10. The two fixing grooves 15 are symmetrically distributed about the central axis of the fixing plate 14. An assembly plate 16 is provided on the side of each fixing plate 14 closest to the movable shell 10. The two assembly plates 16 are respectively installed at the top and bottom of the movable shell 10. An assembly hole 17 is formed on the side of the assembly plate 16 corresponding to the fixing groove 15. The assembly hole 17 is positioned opposite to the fixing groove 15. Two spaced-out holes are provided on the side of the assembly plate 16 furthest from the fixing plate 14. The fastening bolts 18 are respectively positioned corresponding to the two mounting holes 17, and the fastening bolts 18 pass through the mounting holes 17 and extend into the fixing groove 15. The outer side of the fastening bolts 18 is threadedly connected to the inner wall of the fixing groove 15. The movable shell 10 and the fixed shell 9 are assembled and fixed by the threaded connection between the fastening bolts 18 and the fixing groove 15, which can ensure the tightness of the connection between the movable shell 10 and the fixed shell 9. At the same time, the fastening bolts 18 can be removed to separate the movable shell 10 and the fixed shell 9, so as to achieve the effect of convenient assembly and disassembly of the fixed shell 9 and the movable shell 10.
