[0053] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0054] In related technologies, the installation structure of components such as the internal gas tank, molecular sieve tank, and valve body of the oxygen concentrator is complex, which not only increases the difficulty of assembling the oxygen concentrator but also brings inconvenience to subsequent maintenance and repair. Moreover, the complex installation structure makes it difficult to ensure the tightness and stability of the connection between the various components, thereby affecting the airtightness of the internal airflow of the oxygen concentrator and reducing the oxygen production efficiency of the oxygen concentrator.

[0055] The assembly bracket provided in this embodiment enables the compact and convenient installation of the gas storage component and the oxygen supply valve body within a limited space, which helps to improve the overall integration of the internal components of the portable oxygen concentrator and reduce space occupation. At the same time, the intersection of the second direction and the first direction facilitates the connection and airflow transmission between the oxygen supply valve body and the gas storage component, further ensuring the structural compactness and airflow sealing of the portable oxygen concentrator and improving oxygen production efficiency.

[0056] Reference Figure 1 This utility model provides an assembly bracket for use in a portable oxygen concentrator. The assembly bracket includes:

[0057] Framework 1;

[0058] First assembly component 2, the first assembly component 2 is disposed on the frame 1 and extends along the first direction, the first assembly component 2 is used for the gas storage component 200 to be installed on the frame 1 along the first direction;

[0059] The second assembly component 3 is disposed on the frame 1 and has a first through channel 31 extending in the second direction inside. The first through channel 31 is used for the oxygen supply valve body 300 to be installed on the frame 1 in the second direction so that the outlet of the oxygen supply valve body 300 is connected to the gas storage component 200.

[0060] The second direction intersects with the first direction.

[0061] In the above embodiment, frame 1 serves as the basic structure of the entire assembly bracket, providing a support and fixing platform for the assembly components on the assembly bracket, ensuring that each assembly component can be arranged in an orderly manner according to design requirements, thereby forming an integral structure. The assembly bracket 100 also provides a basic framework for subsequent installation and coordination with the internal components of the portable oxygen concentrator, helping to ensure the stability and reliability of the entire assembly structure.

[0062] See Figure 1 and Figure 3 The first assembly component 2 is disposed on the frame 1 along the first direction, providing a clear positioning direction for the installation of the gas storage component 200. This ensures that the gas storage component 200 can be accurately installed onto the assembly bracket 100 in the predetermined direction of the first direction, guaranteeing the accuracy and consistency of the installation. Moreover, the installation cooperation between the assembly bracket 100 and the gas storage component 200 along the first direction simplifies the installation process, improves installation efficiency, and reduces assembly difficulty, facilitating quick disassembly and installation of the gas storage component 200 during subsequent maintenance and repair.

[0063] See Figure 1 The first through-channel 31 inside the second assembly component 3 provides installation space for the oxygen supply valve body 300. The oxygen supply valve body 300 is connected to the assembly bracket 100 along the second direction through the installation and cooperation of the assembly bracket 100 with the oxygen supply valve body 300. Furthermore, with the assembly bracket 100 in place, the outlet of the oxygen supply valve body 300 is connected to the gas storage component 200, ensuring that gas can flow smoothly from the oxygen supply valve body 300 to the gas storage component 200 in one direction, achieving smooth connection of the airflow channels between the internal components of the portable oxygen concentrator. The oxygen supply valve body 300 can have multiple airflow channels, and it can also equalize the airflow in these channels, ensuring the stability of the airflow. Moreover, the connection and cooperation between the oxygen supply valve body 300 and the gas storage component 200 along the second direction ensures the sealing of the airflow channel connection between the oxygen supply valve body 300 and the gas storage component 200, thereby ensuring the oxygen production efficiency of the portable oxygen concentrator.

[0064] See Figure 3 The second direction intersects with the first direction, for example, at an angle of 30°, 60°, 90°, 120°, or 150°. This allows the mounting bracket 100 to make full use of space in its spatial layout. Each assembly component can achieve compact and convenient installation of the gas storage component 200 and the oxygen supply valve body 300 within a limited space, which helps to improve the overall integration of the internal components of the portable oxygen concentrator and reduce space occupation. At the same time, the intersection of the second direction with the first direction also facilitates the connection and airflow transmission between the oxygen supply valve body 300 and the gas storage component 200, further ensuring the structural compactness and airflow sealing of the portable oxygen concentrator and improving oxygen production efficiency.

[0065] It is worth noting that when assembling the gas storage component 200 and the oxygen supply valve body 300, the gas storage component 200 should first be accurately installed onto the assembly bracket 100 in the direction predetermined in the first direction, and then the oxygen supply valve body 300 should be installed and fitted onto the assembly bracket 100 in the second direction. This avoids interference between the gas storage component 200 and the oxygen supply valve body 300, ensuring the installation stability of the gas storage component 200 and the oxygen supply valve body 300, as well as the airflow sealing between the oxygen supply valve body 300 and the gas storage component 200.

[0066] In some embodiments, the second direction is perpendicular to the first direction.

[0067] In the above embodiments, the first direction can be the length direction of the portable oxygen concentrator, and the second direction can be the height direction of the portable oxygen concentrator. The second direction is perpendicular to the first direction, which not only allows the gas storage component 200 to make full use of the space in the length direction inside the portable oxygen concentrator, but also increases the structural stability of the mounting bracket 100, making the connection between the gas storage component 200 and the oxygen supply valve body 300 more secure, reducing the risk of loosening or displacement of the gas storage component 200 and the oxygen supply valve body 300 due to vibration or external force, and ensuring the normal operation of the portable oxygen concentrator.

[0068] In some embodiments, see Figure 1 The first assembly component 2 includes a support plate, which includes a first support plate 21 and a second support plate 22. The first support plate 21 and the second support plate 22 are connected to the frame 1 at intervals and are used to support the gas storage assembly 200.

[0069] A guide gap 23 is formed between the first support plate 21 and the second support plate 22. The guide gap 23 is used to fit into the connecting section 2014 of the gas storage component 200.

[0070] In the above embodiment, the first support plate 21 and the second support plate 22 are spaced apart and connected to the frame 1 to form a stable support platform, which can effectively support the gas storage component 200. Moreover, the spaced connection makes the installation and disassembly of the gas storage component 200 more convenient and improves the efficiency of the gas storage component 200.

[0071] See Figure 1 and Figure 6 The guide gap 23 provides a clear guide for the installation of the gas storage assembly 200. During installation, the operator can insert the connecting section 2014 of the gas storage assembly 200 along the guide gap 23 to ensure that the gas storage assembly 200 is accurately installed on the support plate in the predetermined direction and position, avoiding damage to the assembly or installation failure due to incorrect installation direction. Moreover, the guide gap 23 can limit the shaking and displacement of the gas storage assembly 200 during installation, improving the accuracy and consistency of installation.

[0072] In some embodiments, locking holes (not shown in the figure) are provided on the first support plate 21 and / or the second support plate 22. The locking holes facilitate the locking of the gas storage assembly 200 to the first support plate 21 and the second support plate 22, ensuring the installation stability of the gas storage assembly 200. A receiving space can be formed between the first support plate 21 and the frame 1 to accommodate the gas storage tank of the gas storage assembly 200.

[0073] In some embodiments, see Figure 2 , Figure 3 and Figure 6 The first assembly component 2 includes a first arc segment 24 and a second arc segment 25. The first arc segment 24 is connected to the first support plate 21, and the second arc segment 25 is connected to the second support plate 22.

[0074] The first arc segment 24 and the second arc segment 25 extend toward each other to form a guide groove between the first support plate 21, the first arc segment 24, the second support plate 22, and the second arc segment 25. The guide groove is used to engage with the snap-fit ​​section 2015 of the gas storage assembly 200.

[0075] In the above embodiment, the first arc segment 24 is connected to the first support plate 21 and the second arc segment 25 is connected to the second support plate 22 respectively, forming a three-dimensional support structure. This allows the first support plate 21 and the second support plate 22 to provide more comprehensive support for the gas storage component 200 through the arc segment, thereby enhancing the integrity and stability of the entire support structure.

[0076] The first arc segment 24 extends toward the second arc segment 25, and the second arc segment 25 extends toward the first arc segment 24, so as to ensure that the guide groove guides the installation of the gas storage component 200 while reducing the space occupied by the guide groove. Moreover, the first arc segment 24 and the second arc segment 25 match the arc surface on the snap-fit ​​section 2015 of the gas storage component 200, which can provide a more stable guiding effect for the installation of the gas storage component 200.

[0077] In some embodiments, see Figure 1 and Figure 2 The mounting bracket 100 also includes a third mounting component 4, which is disposed on the frame 1 and has a second through channel 41 extending in a third direction. The second through channel 41 is used for mounting the molecular sieve assembly 400 in the frame 1 in a third direction so that the outlet of the molecular sieve assembly 400 is connected to the inlet of the oxygen supply valve body 300.

[0078] The third direction intersects with the second direction.

[0079] In the above embodiment, the stable structure of the frame 1 provides a reliable mounting base for the third assembly component 4. The second through-channel 41 of the third assembly component 4 provides assembly space for the molecular sieve assembly 400, and the second through-channel 41 extending along the third direction allows the molecular sieve assembly 400 to be accurately installed into the third assembly component 4 in the predetermined direction of the third direction, ensuring the fitting accuracy between the molecular sieve assembly 400 and the assembly bracket 100, and improving the accuracy and convenience of the installation of the molecular sieve assembly 400.

[0080] In the above embodiments, the third direction can be perpendicular to the second direction to make full use of the three-dimensional space inside the oxygen concentrator, allowing the components to be arranged more compactly and orderly in space. For example, the molecular sieve component 400 is installed along the third direction, while the oxygen supply valve body 300 that cooperates with it is installed along the second direction. The vertical layout can avoid mutual interference between the two components, improve space utilization, and make the overall structure of the oxygen concentrator more compact.

[0081] In some embodiments, the first direction is perpendicular to the second direction, and the third direction can be perpendicular to the second direction, making the connection and support relationship between the various components inside the oxygen concentrator more stable. For example, the gas storage component 200 is installed to the mounting bracket 100 along the first horizontal direction, the oxygen supply valve body 300 is installed to the mounting bracket 100 along the second vertical direction, and the molecular sieve component 400 is installed to the mounting bracket 100 along the third horizontal direction. The vertical directional relationship can form a more stable support structure, reduce the shaking and displacement of components during operation, improve the sealing of the gas circuit connection between the molecular sieve component 400 and the oxygen supply valve body 300, and enhance the overall stability and reliability of the oxygen concentrator.

[0082] In some embodiments, see Figure 1 and Figure 2 The mounting bracket 100 also includes a third mounting component 4, which is disposed on the frame 1 and has a second through channel 41 extending in a third direction. The second through channel 41 is used for mounting the molecular sieve assembly 400 in the frame 1 in a third direction so that the outlet of the molecular sieve assembly 400 is connected to the inlet of the oxygen supply valve body 300.

[0083] The third direction intersects with or is parallel to the second direction.

[0084] In the above embodiment, the stable structure of the frame 1 provides a reliable mounting base for the third assembly component 4. The second through-channel 41 of the third assembly component 4 provides assembly space for the molecular sieve assembly 400, and the second through-channel 41 extending along the third direction allows the molecular sieve assembly 400 to be accurately installed into the third assembly component 4 in the predetermined direction of the third direction, ensuring the fitting accuracy between the molecular sieve assembly 400 and the assembly bracket 100, and improving the accuracy and convenience of the installation of the molecular sieve assembly 400.

[0085] See Figure 3 With the oxygen supply valve body 300 installed and engaged with the second assembly component 3 of the assembly bracket 100 along the second direction, and the molecular sieve assembly 400 installed and engaged with the third assembly component 4 of the assembly bracket 100 along the third direction, the gas path connection between the molecular sieve assembly 400 and the oxygen supply valve body 300 is achieved. Oxygen processed by the molecular sieve assembly 400 can smoothly enter the oxygen supply valve body 300 through its outlet, and then enter the gas storage assembly 200 through the oxygen supply valve body 300, ensuring unobstructed airflow within the portable oxygen generator and achieving stable operation of the oxygen production process.

[0086] In addition, when maintenance and repair of the molecular sieve assembly 400 are required, since the molecular sieve assembly 400 is connected to the oxygen supply valve body 300 through the second through-channel 41, the molecular sieve assembly 400 can be easily disassembled and installed through the second through-channel 41, which reduces the difficulty and cost of maintenance and repair.

[0087] See Figure 3 When the third direction intersects with the second direction, that is, the oxygen supply valve body 300 and the molecular sieve assembly 400 can be installed and cooperate with the assembly bracket 100 in different directions, making full use of the three-dimensional space, avoiding mutual interference between the components during assembly, improving the overall utilization rate of the internal space of the portable oxygen concentrator, and helping to reduce the overall volume of the portable oxygen concentrator.

[0088] It is worth noting that the third direction can be parallel to the first direction. For example, the gas storage component 200 and the molecular sieve component 400 can be installed on the mounting bracket 100 from both sides, effectively utilizing the space of the portable oxygen generator in the first and third directions. Alternatively, the third direction can intersect with the first direction, allowing the gas storage component 200, the oxygen supply valve body 300, and the molecular sieve component 400 to be installed on the mounting bracket 100 from three different directions, simplifying the ease of disassembly and assembly of the aforementioned components.

[0089] In other embodiments, the third assembly component 4 and the molecular sieve assembly 400 can also be in sliding fit with a groove and a slide rail. For example, the third assembly component 4 is a slide rail on the assembly bracket 100, and the groove on the molecular sieve assembly 400 is in sliding fit with the slide rail on the assembly bracket 100. This can also ensure that the molecular sieve assembly 400 and the oxygen supply valve body 300 are aligned and connected.

[0090] In some embodiments, see Figure 2 The second perforation channel 41 includes a first molecular sieve channel 411 and a second molecular sieve channel 412;

[0091] The third assembly component 4 includes a first guide 42 and a second guide 43. The first arc segment 24 and the first guide 42 form an annular first molecular sieve channel 411, and the second arc segment 25 and the second guide 43 form an annular second molecular sieve channel 412.

[0092] In the above embodiments, the molecular sieve assembly 400 may include two molecular sieve tanks, which are respectively disposed in the first molecular sieve channel 411 and the second molecular sieve channel 412. When one molecular sieve tank is in the oxygen generation stage, the other molecular sieve tank may be in the nitrogen removal stage, thereby improving the oxygen generation efficiency of the molecular sieve assembly 400.

[0093] See Figure 2 The first guide member 42 and the second guide member 43 provide guidance for the installation of the two molecular sieve tanks, respectively. During installation, the two molecular sieve tanks can smoothly enter the corresponding molecular sieve channels along the guide members, ensuring the accuracy and consistency of the installation of the molecular sieve assembly 400.

[0094] Combination Figure 1 and Figure 2The first arc-shaped segment 24 and the first guide member 42 together form the first molecular sieve channel 411, providing a complete annular installation channel for a molecular sieve tank. The annular channel design better adapts to the shape of the molecular sieve tank, ensuring a tight fit between the molecular sieve tank and the annular channel, thus improving the installation stability of the molecular sieve tank. The second arc-shaped segment 25 and the second guide member 43 form the second annular molecular sieve channel 412, which forms the installation channel for another molecular sieve tank. Furthermore, the first arc-shaped segment 24 and the second arc-shaped segment 25 not only guide the installation of the gas storage assembly 200 but also limit the movement of the molecular sieve assembly 400. The reuse of the first arc-shaped segment 24 and the second arc-shaped segment 25 ensures the structural compactness of the assembly bracket 100 when installing various components.

[0095] In some embodiments, see Figure 1 and Figure 3 The second assembly component 3 includes a connector 32 and a third guide 33. The connector 32 is connected between the third assembly component 4 and the support plate. The third guide 33 has a first through-channel 31 inside.

[0096] The third guide 33 is disposed on the connector 32 and is offset from the support plate of the first assembly component 2 in the second direction to form an assembly space for the gas storage inlet and the valve body outlet.

[0097] In the above embodiments, the second assembly component 3, through the cooperation of the connector 32 and the third guide 33, enables the second assembly component 3 to simultaneously meet the dual requirements of connection and guidance, thereby improving the practicality of the assembly component.

[0098] See Figure 1 The connector 32 establishes a connection between the support plate of the third assembly component 4 and the first assembly component 2, making the entire assembly bracket 100 a unified whole. For example, the first assembly component 2, the second assembly component 3, and the third assembly component 4 are integrally formed on the frame 1, which enhances the structural strength and stability of the assembly bracket 100. The third guide component 33 is offset from the support plate of the first assembly component 2 in the second direction. This ensures stable support of the support plate for the gas storage component 200 while facilitating the assembly of the oxygen supply valve body 300 to the assembly bracket 100 and its relative connection with the gas storage component 200 through the third guide component 33. This improves the space utilization of the assembly bracket 100 and makes the internal structure of the portable oxygen concentrator more compact.

[0099] In some embodiments, the third guide member 33 is provided with a locking hole, which facilitates the locking assembly of the third guide member 33 with the oxygen supply valve body 300 by locking components such as bolts or pins.

[0100] See Figures 4 to 7This utility model provides a portable oxygen generator, which includes a gas storage component 200, an oxygen supply valve body 300 and the aforementioned assembly bracket 100.

[0101] The gas storage assembly 200 can be installed and fitted with the first assembly component 2 along the first direction, and the oxygen supply valve body 300 can be installed and fitted with the first through channel 31 along the second direction, so that the outlet of the oxygen supply valve body 300 is connected to the gas storage assembly 200.

[0102] See Figure 7 The mounting bracket 100 enables the compact and convenient installation of the gas storage component 200 and the oxygen supply valve body 300, which helps to improve the overall integration of the internal components of the portable oxygen concentrator and reduce space occupation. At the same time, the intersection of the second direction and the first direction facilitates the connection and airflow transmission between the oxygen supply valve body 300 and the gas storage component 200, further ensuring the structural compactness and airflow sealing of the portable oxygen concentrator and improving the oxygen production efficiency of the portable oxygen concentrator.

[0103] In the above embodiments, components such as the gas storage component 200 and the oxygen supply valve body 300 are integrated on the mounting bracket 100, so that the portable oxygen generator can form a complete system, with each component cooperating with each other to achieve the oxygen production function.

[0104] In some embodiments, see Figure 4 and Figure 7 The gas storage component 200 includes a gas storage base plate 201 and a gas storage tank 202. The gas storage base plate 201 is mounted on the mounting bracket 100, and the gas storage tank 202 is fixed to the gas storage base plate 201.

[0105] In the above embodiments, the gas storage base plate 201 is mounted on the mounting bracket 100 via the first mounting component 2, providing a stable support foundation for the gas storage tank 202. Simultaneously, the gas storage base plate 201 can bear the weight of the gas storage tank 202 and its internal gas, ensuring that the gas storage tank 202 maintains a stable position during the operation of the portable oxygen concentrator, avoiding safety hazards caused by shaking or tilting. Integrating the gas storage component 200 into the mounting bracket 100 via the gas storage base plate 201 helps optimize the internal space layout of the portable oxygen concentrator and improves space utilization.

[0106] In the above embodiments, the gas storage tank 202 is fixed to the gas storage base plate 201 by plugging or snapping, so as to facilitate the disassembly of the gas storage tank 202. When maintenance, repair or replacement of the gas storage tank 202 is required, the operator can easily remove the gas storage tank 202 from the gas storage base plate 201, reducing the difficulty of maintenance.

[0107] In one embodiment, see Figure 6A sealing sleeve 2013 is fitted over the inlet of the oxygen inlet pipe on the gas storage base plate 201, and the outlet of the gas outlet base assembly 300 is connected to the sealing sleeve 2013, ensuring the sealing between the inlet of the oxygen inlet pipe on the gas storage base plate 201 and the outlet of the gas outlet base assembly 300, and preventing oxygen leakage from the connection gap. In some embodiments, see... Figure 7 The portable oxygen generator includes a molecular sieve assembly 400, which can be installed and fitted with the third assembly part 4 of the mounting bracket 100 in a third direction so that the outlet of the molecular sieve assembly 400 is connected to the inlet of the oxygen supply valve body 300.

[0108] In the above embodiment, the third direction may intersect with the second direction. The second through-channel 41 of the third assembly component 4 provides assembly space for the molecular sieve assembly 400. The second through-channel 41 extending along the third direction enables the molecular sieve assembly 400 to be accurately installed into the third assembly component 4 in the predetermined direction of the third direction, ensuring the fitting accuracy between the molecular sieve assembly 400 and the assembly bracket 100, and improving the accuracy and convenience of the installation of the molecular sieve assembly 400.

[0109] Meanwhile, the third assembly component 4 allows the molecular sieve assembly 400 to be installed onto the assembly bracket 100 in a specific third orientation, which helps to make reasonable use of the internal space of the portable oxygen concentrator. By rationally planning the installation direction and position of each component, the structure of the portable oxygen concentrator can be made more compact, reducing space occupation and improving the overall integration of the portable oxygen concentrator.

[0110] See Figure 5 The relative connection method ensures the sealing between the outlet of the molecular sieve assembly 400 and the inlet of the oxygen supply valve body 300, reduces the resistance of the airflow during transmission, helps to ensure that the gas can flow smoothly from the molecular sieve assembly 400 to the oxygen supply valve body 300, and improves the transmission efficiency of the airflow.

[0111] In some embodiments, see Figure 7 The portable oxygen concentrator includes an inner cavity support 600, which is arranged at intervals relative to the mounting support 100.

[0112] The inner cavity support 600 is provided with a third through channel 601, and the molecular sieve assembly 400 can be installed and cooperated with the second through channel 41 and the third through channel 601 of the third assembly component 4 in a third direction to limit the two ends of the molecular sieve assembly 400.

[0113] In the above embodiments, the inner cavity support 600 and the assembly support 100 are arranged at intervals, providing more space options for the installation and layout of other components, making the arrangement of the components inside the portable oxygen concentrator more orderly. The third through-channel 601 provides further guidance for the installation of the molecular sieve assembly 400. The third through-channel 601 cooperates with the second through-channel 41 of the third assembly component 4, enabling the molecular sieve assembly 400 to be positioned more accurately when installed along the third direction, reducing deviations and shaking during the installation process, and jointly forming guidance and support for both ends of the molecular sieve assembly 400, improving the installation accuracy and stability of the molecular sieve assembly 400.

[0114] In some embodiments, the portable oxygen concentrator further includes a housing and a compression assembly 800, with an air intake hood provided on the housing and a mounting bracket 100 disposed inside the housing on the side near the air intake hood;

[0115] The first assembly component 2 is located in the middle of the assembly bracket 100, the third assembly component 4 is located at the bottom of the assembly bracket 100, the gas storage component 200 and part of the molecular sieve component 400 are arranged vertically, and the compression component 800 and part of the molecular sieve component 400 are arranged vertically.

[0116] In the above embodiments, the air intake hood provides a channel for external air to enter the portable oxygen concentrator. During the oxygen production process, air needs to be continuously drawn in from the outside for subsequent oxygen separation operations. The multiple air intake holes on the air intake hood ensure that air can smoothly enter the portable oxygen concentrator, providing the necessary air source for the oxygen production process. Moreover, the air intake hood usually has a certain filtration function, which can prevent dust, impurities, and other particulate matter in the outside air from entering the portable oxygen concentrator.

[0117] Combination Figure 7 The first assembly component 2 is positioned in the middle of the assembly bracket 100, ensuring good balance and stability when supporting components such as the gas storage component 200, thus improving the reliability of the entire assembly structure. The third assembly component 4 is located at the bottom of the assembly bracket 100, utilizing gravity to assist in the installation and fixation of the molecular sieve component 400. Furthermore, during installation, the molecular sieve component 400's own weight allows for more stable engagement with the second through-channel 41 of the third assembly component 4, reducing operational difficulty during installation and enhancing installation stability.

[0118] See Figure 7The vertical arrangement of the gas storage component 200 and part of the molecular sieve component 400 fully utilizes the vertical space inside the portable oxygen concentrator, allowing more components to be installed within a limited space. This improves the space utilization and overall integration of the portable oxygen concentrator, contributing to a smaller and more compact size. The compression component 800 provides high-pressure air for the oxygen production process, while the molecular sieve component 400 separates oxygen. This vertical arrangement allows the high-pressure air generated by the compression component 800 to be delivered more directly to the molecular sieve component 400, reducing gas leakage and energy loss in intermediate stages and improving oxygen production efficiency.
