Description

Technical Field

[0001] This utility model belongs to the field of oxygen generator technology, and in particular relates to a sealing structure for the oxygen outlet circuit of an oxygen generator. Background Technology

[0002] The oxygen output sealing structure of an oxygen concentrator is used in the oxygen output pipeline system of an oxygen concentrator. Through the design of specific sealing elements and connection structures, it achieves high airtightness of the oxygen output path, prevents oxygen leakage, ensures oxygen purity and stable delivery pressure, and adapts to pressure changes during the operation of the oxygen concentrator.

[0003] In the working process of an oxygen concentrator, air is pressurized by a compressor and separated by molecular sieve adsorption. Oxygen needs to be delivered to components such as the gas storage tank and humidification cup through the oxygen outlet path for final supply. Oxygen production relies on the principle of pressure swing adsorption. If there is a leak in the oxygen outlet path, it will disrupt the pressure balance inside the molecular sieve tower, leading to nitrogen adsorption. Therefore, we need to design a sealing structure for the oxygen outlet path of the oxygen concentrator to prevent oxygen leakage, maintain the internal pressure balance of the oxygen concentrator, help the molecular sieve and other components work normally, improve the purity of oxygen production, prevent impurities from mixing into the oxygen, and extend the service life of the oxygen concentrator.

[0006] Preferably, a sealing ring is provided at the bottom of the mounting component, and the sealing ring is fitted onto the surface of the oxygen outlet straight connector.

[0022] In the following description, embodiments of the oxygen generator outlet sealing structure of this utility model will be described with reference to the accompanying drawings.

[0023] Figure 1-5 This invention illustrates an embodiment of an oxygen concentrator's oxygen outlet sealing structure, comprising an oxygen outlet straight connector 2 connected to the top right side of the oxygen concentrator body 1. A sheet metal part 3 is mounted on the top right side of the oxygen concentrator body 1, and a mounting part 4 is fixedly connected to the top of the sheet metal part 3 by bolts. The oxygen outlet straight connector 2 passes through the central axis of the surface of the mounting part 4. A sealing sleeve 5 is fitted onto the bottom of the surface of the oxygen outlet straight connector 2, located between the top of the sheet metal part 3 and the bottom of the mounting part 4. A threaded sleeve 6 is fitted onto the surface of the sealing sleeve 5. A sealing ring 7 is provided at the bottom of the mounting part 4, fitted onto the surface of the oxygen outlet straight connector 2. Through the setting of the sealing ring 7, the sealing ring 7 can effectively prevent oxygen leakage, ensure stable oxygen concentration and pressure, maintain the internal pressure balance of the oxygen concentrator body 1, and assist the molecular sieve core component in efficiently separating oxygen. Its elastic characteristics can compensate for minor deviations during operation and adapt to pressure fluctuations during the operation of the oxygen concentrator body 1. The threaded sleeve 6 surface A sealing ring 9 is fitted at the bottom of the sheet metal part 3. A fixing ring 8 is provided on the right side of the top of the sheet metal part 3. The fixing ring 8 is fixed to the bottom of the surface of the sealing ring 9. Multiple Z-shaped blocks 10 are fixedly connected to the surface of the sealing ring 9 and the fixing ring 8. The bottom of the multiple Z-shaped blocks 10 is fixedly connected to the sheet metal part 3. Through the setting of the Z-shaped blocks 10, the Z-shaped blocks 10 are evenly distributed in the circumferential direction. The bottom surface of the Z-shaped blocks 10 can form a contact constraint with the top of the sheet metal part 3, evenly distribute the load, and improve the stability of the connection between the sealing sleeve 5, the fixing ring 8, the sealing ring 9 and the top of the sheet metal part 3. A lower retaining tooth 12 is provided at the top of the sealing ring 9. A spring washer 11 is installed at the top of the sealing ring 9. The spring washer 11 is tightly connected to the lower retaining tooth 12. A connecting ring 13 is provided on the surface of the threaded sleeve 6. An upper retaining tooth 14 is fixedly connected to the bottom of the connecting ring 13. The lower retaining tooth 12 and the upper retaining tooth 14 are adapted to each other. A nut 15 is threadedly connected to the surface of the threaded sleeve 6. The nut 15 is fixedly connected to the connecting ring 13.

[0024] Working principle: When using this utility model, the user places the sealing sleeve 5 on the surface of the oxygen outlet connector 2, which is located at the top of the sheet metal part 3 and the bottom of the mounting part 4. Then, the threaded sleeve 6 is placed on the surface of the sealing sleeve 5, and the sealing ring 9 is installed on the surface of the threaded sleeve 6, so that the fixing ring 8 is installed on the surface of the sealing ring 9. At this time, multiple Z-shaped blocks 10 are fixed on the top of the sheet metal part 3, and the opposite side of the multiple Z-shaped blocks 10 is fixed with the fixing ring 8 and the sealing ring 9. This makes the connection between the oxygen generator body 1 and the oxygen outlet connector 2 well sealed, ensuring that the oxygen concentration and flow rate output by the oxygen generator body 1 are relatively stable. Then, the nut 15 is rotated, and the nut 15 will drive the upper locking tooth 14 to move downward through the connecting ring 13. The upper locking tooth 14 and the lower locking tooth 12 engage. Then, the sealing ring 7 seals the connection between the mounting part 4 and the oxygen outlet connector 2. Finally, the flow rate of the oxygen generator body 1 is relatively stable, preventing impurities from mixing into the oxygen.

[0025] In summary, the oxygen output circuit sealing structure of this oxygen concentrator seals the connection of the oxygen output straight connector 2 with the sealing sleeve 5. Through the cooperation of the sealing ring 9, the lower retaining tooth 12, and the connecting ring 13, the connection between the oxygen concentrator body 1 and the oxygen output straight connector 2 is prevented from leaking oxygen. This allows the oxygen output straight connector 2 to output oxygen stably, thereby ensuring a relatively stable output oxygen concentration and flow rate, preventing impurities from mixing into the oxygen, extending the service life of the oxygen concentrator, and improving the purity of the oxygen produced.
