Description

A modular oxygen generator Technical Field

[0001] This invention relates to the field of oxygen generation equipment technology, and more particularly to a modular oxygen generator. Background Technology

[0002] Currently, home oxygen concentrators primarily rely on air compressors to compress air and then separate and extract oxygen from the air using molecular sieves, providing relatively pure oxygen for home use. In common home oxygen concentrator designs, the molecular sieve tank and air compressor are integrated as core components within the device. However, this integrated design has some shortcomings, particularly since the lifespan of the molecular sieve is crucial to the performance of the oxygen concentrator. Once it ages or fails, users often need to replace the entire device, which not only increases operating costs but also limits the maintainability and sustainability of the equipment.

[0003] Patent CN210656150U discloses an oxygen concentrator with a detachable module that can be removed from the main body. This design integrates the compressor and molecular sieve tank within the detachable module, allowing the module to be removed from the main body for individual replacement or maintenance when either the molecular sieve tank or the compressor needs to be replaced or maintained. This design addresses, to some extent, the difficulties in oxygen concentrator maintenance and the high operating costs. However, because the molecular sieve tank and compressor share a single detachable module, the entire module still needs to be disassembled when only the molecular sieve tank or compressor needs to be replaced, resulting in cumbersome disassembly and assembly operations and hindering users from performing more precise maintenance.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0072] Referring to Figures 1-23, some embodiments of the modular oxygen concentrator of the present invention are shown. The modular oxygen concentrator of the present invention is characterized by its highly modular design and convenient disassembly and assembly, which not only facilitates maintenance and replacement of parts, but also greatly improves the flexibility and portability of the oxygen concentrator.

[0073] As shown in Figures 1 and 2, the oxygen generator in this embodiment is a modular oxygen generator, including a main frame module 10 and various functional modules that can be disassembled and assembled with the main frame module 10. Each functional module includes a compressor module 20, a molecular sieve module 30, and a battery module 40.

[0074] The main frame module 10 is the main body of the modular oxygen generator, mainly used to connect and support the various functional modules.

[0075] The compressor module 20 includes a compressor housing assembly 21 and a compressor 22 disposed within the compressor housing assembly 21. The compressor 22 draws in outside air and compresses it to a certain pressure, providing the necessary power and pressure conditions for the subsequent air separation process.

[0076] Molecular sieve module 30 is the core component of the oxygen generator that achieves oxygen separation. It utilizes specific molecular sieve materials to separate oxygen and nitrogen from compressed air through the principles of adsorption and desorption.

[0077] Battery module 40 provides power to the entire oxygen concentrator. It typically uses high-performance lithium batteries or rechargeable battery packs to ensure continuous operation even during power outages or when the machine is in motion. Battery module 40 not only powers key components such as compressor 22 and molecular sieve tanks, but also ensures the oxygen concentrator's portability and battery life, making it suitable for various scenarios and user needs.

[0078] As shown in Figure 6, the main frame module 10 includes a main support 11, an oxygen storage tank 14 housed within the main support 11, and a control component 12. The main support 11 serves as the primary support structure. The oxygen storage tank 14 is connected to the molecular sieve module 30 and is used to store the produced oxygen. The control component 12 is used for electrical control of the oxygen generator, responsible for controlling the entire workflow of the oxygen generator and the coordinated operation between various modules.

[0079] Referring to Figure 5, the compressor module 20 is located on one side of the main bracket 11 and is slidably detachably connected to the main bracket 11 through the first disassembly structure C1.

[0080] The molecular sieve module 30 is located on the other side of the main support 11 and is slidably detached from the main support 11 via the second disassembly structure C2.

[0081] The battery module 40 is located on the lower side of the main bracket 11 and is slidably detachably connected to the main bracket 11 through a third disassembly structure.

[0082] The compressor module 20, molecular sieve module 30, and battery module 40 are electrically connected to the main frame module 10 via power connectors. These power connectors are not only simple in design but also allow for quick connection and disconnection, ensuring rapid and stable electrical connections between the functional modules and the main frame module 10.

[0083] As shown in Figure 7, the main frame module 10 is equipped with a compressor gas inlet 191 that connects to the outlet of the compressor module 20, and a molecular sieve gas inlet 192 that connects to the inlet and outlet of the molecular sieve module 30. The compressor gas inlet 191, molecular sieve gas inlet 192, and oxygen storage tank 14 are sequentially connected via pipelines to achieve gas path connectivity. After the compressor module 20 and molecular sieve module 30 are slidably installed, they can be quickly connected via the compressor gas inlet 191 and molecular sieve gas inlet 192. The compressor gas inlet 191 and molecular sieve gas inlet 192 are then connected to the oxygen storage tank 14 via pipelines, ensuring smooth gas flow and efficient oxygen separation.

[0084] The modular oxygen concentrator described above, through its modular design, allows the compressor module 20, molecular sieve module 30, and battery module 40 to be installed independently and quickly disassembled. This not only improves the independence of each functional module but also greatly simplifies the maintenance and replacement operations of the oxygen concentrator. In actual use, when a module malfunctions or needs periodic replacement, the user can replace the corresponding module individually as needed, without the need for complex disassembly or repair of the entire device. This not only reduces maintenance costs and downtime but also improves the long-term stability of the oxygen concentrator.

[0085] Furthermore, the modular design significantly enhances the scalability and adaptability of the oxygen concentrator. Users can select different specifications of compressor module 20, molecular sieve module 30, and battery module 40 according to their actual needs, thus flexibly adjusting the device's functionality based on environmental changes or usage scenarios. For example, in more static applications, users may require longer battery life and can choose a larger capacity battery module 40; while in situations requiring efficient oxygen supply, they may need to choose a more powerful compressor module 20 and / or a more efficient molecular sieve module 30. This highly flexible module selection allows the oxygen concentrator to be widely used in various fields such as homes, hospitals, wilderness areas, and emergency rescue.

[0086] In some embodiments of this application, as shown in FIG4, one side of the main bracket 11 is a side opening structure, and a second sliding groove structure is provided between the upper end and / or lower end of the side opening structure and the compressor module 20. The compressor module 20 can be disassembled and assembled in the horizontal direction through the second sliding groove structure.

[0087] The other side of the main support 11 is a semi-open structure, and the molecular sieve module 30 is located in the semi-open structure. A third sliding groove structure is provided between the side of the semi-open structure and the molecular sieve module 30. The molecular sieve module 30 can be disassembled and assembled in the vertical direction through the third sliding groove structure.

[0088] Specifically, the compressor module 20 and the molecular sieve module 30 are respectively horizontally disassembled from the main support 11 using a side-opening structure and vertically disassembled from the main support 11 using a semi-open structure, considering that:

[0089] The compressor is basically a horizontally placed structural component, which makes horizontal installation more convenient. At the same time, the compressor module 20 usually needs to be equipped with a corresponding fan assembly and air intake structure on top for heat dissipation and air intake. Therefore, there needs to be a certain amount of equipment structure installation space on top of it. Moreover, the compressor module 20 will vibrate during operation. Therefore, the side opening structure and horizontal placement can effectively ensure its stability after installation.

[0090] The performance of the molecular sieve module 30 is primarily related to the amount of molecular sieve it contains; the more molecular sieve, the better the treatment effect. Therefore, a semi-open structure can significantly extend the length of the molecular sieve module 30. Simultaneously, the semi-open structure facilitates the later assembly and disassembly of the molecular sieve module. Another point to consider is the accuracy and reliability of the molecular sieve module during gas path connection. Vertical installation, compared to other methods, avoids the impact of the molecular sieve's own weight on connection accuracy, thus improving airtightness.

[0091] Furthermore, based on the above-mentioned structural setup, the installation and disassembly method of the battery module 40 was designed, as shown in Figure 3. A first sliding groove structure is provided between the battery module 40 and the bottom surface of the main bracket 11, which allows the battery module 40 to be installed and disassembled in the horizontal direction.

[0092] The battery module 40 is installed on the bottom surface of the main bracket 11 for two reasons: firstly, it is relatively easy to install and can be quickly disassembled, and the disassembly process will not affect the compressor module 20 and the molecular sieve module 30; secondly, corresponding logic design has been carried out for the disassembly steps to reduce the occurrence of equipment risks.

[0093] Specifically, when the battery module 40 is not disassembled, the first disassembly structure C1 and the second disassembly structure C2 are locked to ensure a secure connection between the modules. After the battery module 40 is disassembled, the first disassembly structure C1 and the second disassembly structure C2 can be unlocked, allowing the user to freely disassemble and assemble the compressor module 20 and the molecular sieve module 30.

[0094] This avoids leakage of electricity or gas in principle. After the battery module 40 is removed, all components of the equipment are in a state of power failure and the equipment will not run. At this time, it is very safe and reliable to disassemble and assemble the compressor module 20 and the molecular sieve module 30.

[0095] Specifically, referring to Figure 6, the main support 11 is composed of a base part 111, a vertical frame part 112 and an upper frame part 113.

[0096] The base portion 111 is used to support the entire structure, the vertical frame portion 112 is vertically disposed above the base portion 111, and the upper frame portion 113 is connected to the top of the vertical frame portion 112 and located on one side thereto, so as to form the top structure of the oxygen concentrator.

[0097] To achieve modular installation of the compressor module 20 and the molecular sieve module 30, as shown in Figure 4, a first region A is formed between one side of the vertical frame 112, the bottom surface of the upper frame 113, and the base 111. Region A has a side-opening structure, and the compressor module 20 is installed within it. A second region B is formed between the other side of the vertical frame 112 and the base 111, forming a semi-open structure. The molecular sieve module 30 is installed within this semi-open structure. This semi-open structure allows for a larger volume of the molecular sieve module 30, increasing oxygen production efficiency.

[0098] The oxygen storage tank 14 is vertically installed in the vertical frame portion 112 of the main support 11, so that the oxygen storage tank 14 can be compactly arranged in the structure of the main support 11, saving the horizontal space of the equipment.

[0099] Further, referring to Figures 3 and 4, during the assembly of the oxygen concentrator, the compressor module 20 and the molecular sieve module 30 need to be assembled first, and then inserted into the main support 11. As shown in Figure 4, the compressor module 20 moves to the right and is horizontally inserted into the first region A of the main support 11, and is fixed to the main support 11 by the first disassembly structure C1; the molecular sieve module 30 is pressed into the second region B on the right side of the main support 11 from top to bottom, and is fixed to the main support 11 by the second disassembly structure C2; ​​finally, the battery module 40 is slid from the left to the right into the bottom of the main support 11 and is fixed to the main support 11 by the third disassembly mechanism.

[0100] Similarly, when disassembling the compressor module 20 and the molecular sieve module 30, the locking state of the third disassembly mechanism needs to be released. First, slide the battery module 40 to the left to disassemble it. Then, when disassembling the compressor module 20, release the locking state of the first disassembly structure C1 and drag the compressor module 20 horizontally to the left. When disassembling the molecular sieve module 30, release the locking state of the second disassembly structure C2 and move the molecular sieve module 30 vertically upward.

[0101] By designing the above-described disassembly and assembly logic, the battery module 40 must be disassembled before the compressor module 20 and the molecular sieve module 30 can be disassembled. This design prevents the battery module 40 from being accidentally operated or damaged during the disassembly of the compressor module 20 and the molecular sieve module 30, thereby improving operational safety.

[0102] The following sections will describe in detail the operating path of the oxygen flow of the modular oxygen generator of this application.

[0103] Referring to Figure 8, an air inlet 1131 is provided on the side of the upper frame portion 113 of the main support 11, and an air outlet 1132 is provided on the top surface of the side opening structure. Outside air enters through the air inlet 1131 and is discharged through the air outlet 1132, forming an oxygen-generating flow.

[0104] Referring to Figure 10, the top of the compressor housing assembly 21 is provided with an air inlet chamber 212 corresponding to the air outlet 1132.

[0119] The following sections will describe in detail the sliding and disassembly structure of the compressor module 20.

[0120] In some embodiments of this application, the compressor module 20 is horizontally slidably connected to the top surface of the base portion 111 via a second sliding groove structure. That is, the compressor module 20 is installed and removed in a horizontal direction.

[0121] Specifically, as shown in Figures 7 and 11, the second sliding groove structure includes at least two second slot limiting members 1113, which are respectively disposed on the top surface of the base portion 111, and the two second slot limiting members 1113 are arranged opposite to each other. The compressor module 20 has downwardly extending limiting edges 211 on two opposite sides of its bottom. The compressor module 20 can slide along the second slot limiting members 1113 via the limiting edges 211. The limiting edges 211 are preferably located on the outer side of the second slot limiting members 1113. The second sliding groove structure not only serves as a sliding guide for the compressor module 20, but also restricts other horizontal displacements of the compressor module 20. The vertical displacement of the compressor module 20 is limited by the structure of the main support 11.

[0122] In some embodiments of this application, the first disassembly structure C1 includes a filter chamber opening 215 at the bottom of the compressor module 20, a main frame opening 1118 at the main support 11, and a cover 1104.

[0123] The filter chamber opening 215 connects to a filter chamber located within the compressor module 20, which is used for filtering the intake air of the compressor 22. Filter cotton can be placed inside the filter chamber.

[0124] The cover 1104 is detachably disposed at the filter chamber opening 215 for opening or closing the filter chamber.

[0125] The main frame opening 1118 is formed on the main support 11, and its opening size is adapted to the cover 1104 so that the cover 1104 can be disassembled or installed through the main frame opening 1118.

[0126] The cover 1104 has a cover extension 11041 that extends at least partially into the main frame opening 1118 to restrict sliding movement between the compressor module 20 and the main support 11.

[0127] During installation, the compressor module 20 is inserted into the side opening structure of the main bracket 11 along the sliding direction. When installed in place, the filter chamber opening 215 corresponds to the main bracket opening 1118. Then, the cover 1104 is installed through the main bracket opening 1118, closing the filter chamber opening 215 and limiting the compressor housing assembly 21 and the main bracket 11. During disassembly, the cover 1104 is first removed through the main bracket opening 1118, releasing the cover 1104 from restricting the position of the compressor housing assembly 21 and the main bracket 11. Then, the compressor module 20 is removed from the side opening structure.

[0128] Furthermore, the first disassembly structure C1 also includes a limiting connector, which is disposed between the main support 11 and the compressor module 20 to connect the main support 11 and the compressor module 20. When only the cover 1104 needs to be removed for cleaning or replacement of the filter cotton, the limiting connector ensures a stable connection between the compressor module 20 and the main support 11. In some embodiments, the limiting connector is a quick-release bolt.

[0129] In some other embodiments of this application, as shown in FIG11, the limiting connector is a compressor button 23, which is disposed on the compressor module 20; the main bracket 11 is provided with a limiting through hole 1117, and the compressor button 23 is inserted into the limiting through hole 1117 for locking.

[0130] As shown in Figure 7, a limiting through hole 1117 is vertically disposed on the base portion 111 of the main bracket 11. The compressor button 23 is located at the bottom of the compressor module 20. The compressor button 23 is inserted into the limiting through hole 1117 to achieve locking. When pressed, the compressor button 23 moves upward and exits the limiting through hole 1117, thereby releasing the locked state between the compressor button 23 and the limiting through hole 1117.

[0131] Furthermore, the first disassembly structure C1 also includes a spring (not shown), which is connected to the compressor button 23 to keep the compressor button 23 in a locked state and to reset it after being pressed.

[0132] With the first disassembly structure C1, when disassembling the compressor module 20, the user only needs to remove the cover 1104 and then press the compressor button 23 to easily remove the compressor module 20.

[0133] Since the compressor button 23 is located inside the base 111, after the battery module 40 is disassembled, the cover 1104 can be removed first through the main frame opening 1118, and then the compressor button 23 can be pressed through the limiting through hole 1117 to achieve quick disassembly of the compressor module 20.

[0134] The following sections will describe in detail the sliding and disassembly structure of the molecular sieve module 30.

[0135] In some embodiments of this application, the molecular sieve module 30 is vertically slidably connected to the side of the vertical frame 112 via a third sliding groove structure. That is, the molecular sieve module 30 is installed and disassembled in the vertical direction.

[0136] Specifically, as shown in Figures 6 and 14, the third chute structure includes at least two third slot limiting members 1121, which are respectively disposed on the side of the vertical frame 112. The two third slot limiting members 1121 are arranged opposite to each other to form a chute. The side of the molecular sieve module 30 is provided with a third sliding part 31, which is slidably installed in the chute and engages with the third slot limiting members 1121 to limit the displacement of the molecular sieve module 30 in the direction perpendicular to the sliding direction (horizontal direction).

[0137] During installation, the operator simply slides the molecular sieve module 30 vertically along the third sliding groove structure, allowing it to quickly reach its approximate installation position, significantly reducing adjustment time and difficulty. The second disassembly structure C2, after the molecular sieve module 30 has slid into place, quickly and securely fixes it to the main support 11, completing the installation process. For disassembly, first release the locking mechanism of the second disassembly structure C2, then slide the molecular sieve module 30 out along the third sliding groove structure.

[0138] In some embodiments of this application, as shown in Figures 12 and 13, the second disassembly structure C2 includes a locking groove 32 on the bottom surface of the molecular sieve module 30, a locking member 15 on the base portion 111 of the main support 11, and a molecular sieve button 16.

[0139] The locking element 15 and the molecular sieve button 16 are movably mounted on the main support 11. Specifically, a molecular sieve button mounting hole 1115 for mounting the molecular sieve button 16 is provided on the bottom surface of the base portion 111, and the molecular sieve button 16 is slidably disposed within the molecular sieve button mounting hole 1115. The locking element 15 locks the molecular sieve module 30 after engaging with the locking groove 32 by moving, and unlocks it after exiting the locking groove 32. In this embodiment, the mounting and dismounting direction of the molecular sieve module 30 is perpendicular to the movable direction of the locking element 15.

[0140] With the second disassembly structure C2, the molecular sieve module 30 can be aligned with the main support 11 and moved into place along the loading and unloading direction. Then, the locking member 15 can be pushed to insert into the locking groove 32 to complete the locking. At the same time, the loading and unloading direction of the molecular sieve module 30 is set perpendicular to the movable direction of the locking member 15, which makes the locking fit between the locking member 15 and the locking groove 32 highly stable and reduces the shaking gap after the molecular sieve module 30 is installed.

[0141] Since the molecular sieve button 16 is located on the bottom surface of the base 111, the molecular sieve module 30 can be quickly disassembled by pressing the molecular sieve button 16 after the battery module 40 is disassembled.

[0142] In some other embodiments of this application, as shown in Figures 14-16, the second disassembly structure C2 includes a locking claw 33 disposed on the bottom surface of the molecular sieve module 30, a latch 1114 disposed on the base portion 111 and matching the locking claw 33, and a molecular sieve button 17 for releasing the locking claw 33 and the latch 1114 from the locked state.

[0143] The locking claw 33 extends along the installation direction of the molecular sieve module 30, that is, the locking claw 33 is set vertically. The loading and unloading direction of the molecular sieve module 30 is parallel to the movement direction of the molecular sieve button 17 when it is released from locking.

[0144] With the second disassembly structure C2, users can easily remove the molecular sieve module 30 by simply pressing the molecular sieve button 17. The entire process requires no complicated tools or professional maintenance skills, greatly reducing the difficulty of operation. Furthermore, this simple structure and clear movement method ensure the reliability of the locking and unlocking functions of the molecular sieve module 30 during the use of the oxygen concentrator, helping to reduce malfunctions.

[0145] In this embodiment, a molecular sieve button mounting hole 1116 for mounting the molecular sieve button 17 is provided on the base part 111. Since the molecular sieve button 17 is located on the bottom surface of the base part 111, the molecular sieve module 30 can be quickly disassembled by pressing the molecular sieve button 17 after the battery module 40 is disassembled.

[0146] In other embodiments of this application, as shown in Figures 17 and 18, the second disassembly structure C2 includes a molecular sieve fastener 18 located at the bottom of the main support 11 and a fastening hole 37 formed on the molecular sieve module 30. The fastening hole 37 is matched with the molecular sieve fastener 18. A rotation locking structure is adopted between the fastening hole 37 and the molecular sieve fastener 18. It can be configured such that the fastening hole 37 is a threaded hole, and the upper end of the molecular sieve fastener 18 has a matching external thread.

[0147] Molecular sieve fasteners 18 are positioned vertically, and a through hole is provided on the molecular sieve gas inlet seat 192 for the fasteners 18 to pass through. The fasteners 18 passing through the gas inlet seat improve the stability of the molecular sieve gas inlet port 34 and oxygen outlet port 35 after the molecular sieve module 30 is installed and fixed, preventing gas leakage and other problems that could affect the normal operation of the equipment due to an unstable connection between the molecular sieve gas inlet port 34 and oxygen outlet port 35.

[0148] The molecular sieve fastener 18 has a fastening post 181 and a handle 182 located at the lower end of the fastening post 181. A receiving groove 1119 for accommodating the handle 182 is provided at the lower end of the base portion 111. The receiving groove 1119 provides space for the handle 182, making the structure more compact and rational. A connecting hole is provided between the through hole and the receiving groove 1119, and the through hole and connecting hole are coaxially arranged. The molecular sieve fastener 18 passes through the receiving groove 1119, the connecting hole, and the through hole from bottom to top, and is then fastened into the fastening hole 37; this ensures a smooth insertion path for the molecular sieve fastener 18, facilitates installation in a reasonable sequence, and guarantees that the entire connection and fixing process can be completed efficiently and accurately.

[0149] The following sections will describe in detail the sliding and detachable structure of the battery module 40.

[0150] In some embodiments of this application, referring to Figures 6 and 19, the first sliding groove structure includes at least two first slot limiting members 1112, respectively disposed on the bottom surface of the base portion 111. The two first slot limiting members 1112 are arranged opposite to each other to form a sliding groove. The battery module 40 is provided with a sliding portion 411, which is slidably installed in the sliding groove and engages with the first slot limiting members 1112 to limit the displacement of the battery module 40 in the direction perpendicular to the sliding direction. This design of double limiting members and sliding groove structure effectively improves the stability of the sliding connection of the battery module 40, while avoiding tilting or shaking of the battery module 40 caused by external forces, making the installation of the battery module 40 more stable and reliable.

[0151] In some embodiments of this application, as shown in Figures 20-22, the third disassembly structure includes a limiting slot 1111 on the bottom surface of the main bracket 11 and a quick-release assembly 43 on the battery module 40.

[0152] The battery module 40 includes a battery module housing 41 and a battery assembly 42 disposed within the battery module housing 41. A quick-release assembly 43 is installed within the battery module housing 41.

[0153] As shown in Figure 22, the quick-release assembly 43 includes a battery button 431 and a latching member 432. As shown in Figure 21, the latching member 432 engages with the limiting slot 1111 to limit the displacement of the battery module 40 along the sliding direction. The battery button 431 is configured to drive the latching member 432 to move, causing the latching member 432 to disengage from the limiting slot 1111, thereby releasing the engagement between the latching member 432 and the limiting slot 1111.

[0154] Specifically, the latching member 432 slides in a direction perpendicular to the sliding direction of the battery module 40 and is disposed inside the battery module housing 41. A through hole 412 is formed on the battery module housing 41, opposite to the limiting slot 1111. The latching member 432 extends through the through hole 412 and engages with the limiting slot 1111. The battery button 431 is located on one side of the latching member 432. Pressing the battery button 431 drives the latching member 432 to exit the limiting slot 1111, thereby completing the quick-release operation of the battery module 40.

[0155] The battery module housing 41 has a battery button mounting hole 413, and the battery button 431 is installed in the battery button mounting hole 413. The pressing direction of the battery button 431 is perpendicular to the sliding direction of the latch 432. In this embodiment, the battery button 431 is installed on the side of the battery module housing 41, and the pressing direction of the battery button 431 is perpendicular to the side of the battery module housing 41, which facilitates the application of external force to the battery button 431.

[0156] Furthermore, the quick-release assembly 43 also includes an elastic element 433, which is connected to the latching element 432. The elastic element 433 is used to maintain the latching element 432 in engagement with the limiting slot 1111 when the battery button 431 is not pressed, and to automatically reset the latching element 432 after the battery button 431 is released. The introduction of the elastic element 433 significantly improves the operational safety and convenience of the quick-release assembly 43. After the user completes the operation, it can be restored to its initial state without any additional steps, thereby avoiding the problem of the battery module 40 failing to lock properly due to improper operation.

[0157] Referring to Figure 22, the battery button 431 is designed to include a battery button body 4311 and a force-applying part 4312 protruding from the battery button body 4311. The force-applying part 4312 has an inclined force-applying surface f. The latching member 432 has a receiving surface h that cooperates with the force-applying surface f. The battery button 431 drives the latching member 432 to move in a direction away from the limiting slot 1111 through the interaction between the force-applying surface f and the receiving surface h.

[0158] In some embodiments of this application, the quick-release assembly 43 further includes a mounting base 434, which is fixedly connected to the battery module housing 41. The latching member 432 and the battery button 431 are both slidably disposed on the mounting base 434. The mounting base 434 provides a stable working platform for the latching member 432 and the battery button 431. Furthermore, the latching member 432 and the battery button 431 can be assembled before the mounting base 434 and then installed as a whole on the battery module housing 41, improving assembly and disassembly efficiency.

[0159] The following sections will describe in detail the airflow path of the heat dissipation system in the modular oxygen generator of this application.

[0160] In some embodiments of this application, as shown in Figures 6 and 8, in order to dissipate heat from the compressor module 20, an air outlet 1133 is provided on the bottom surface of the upper frame portion 113 of the main bracket 11 and the top surface of the side opening structure. A fan 13 is provided inside the upper frame portion 113 inside the air outlet 1133. The fan 13 can drive air to enter through the air inlet 1131 and be discharged through the air outlet 1133.

[0161] The airflow entering through the air inlet 1131 and exiting through the air outlet 1133 forms a cooling airflow. The top of the compressor housing assembly 21 is provided with an air inlet area 214 corresponding to the air outlet 1133, as shown in Figure 10. The cooling airflow flows into the compressor housing assembly 21 through the air inlet area 214 to cool the internal compressor 22.

[0162] In this embodiment, part of the outside air entering through the air inlet 1131 is discharged through the air outlet 1132 to form an oxygen-generating flow, and part of the outside air is discharged through the air outlet 1133 to form a heat dissipation flow.

[0163] The cooling airflow entering the compressor module 20 cools the compressor 22, and the hot air can be output in two parts: one part is discharged to the outside, and the other part flows to the molecular sieve module 30 to heat the internal molecular sieve.

[0164] Specifically, as shown in Figures 10 and 11, the compressor housing assembly 21 is provided with an external heat dissipation port 216 and an internal heat dissipation port 217. Part of the heat dissipation airflow is output to the outside through the external heat dissipation port 216; part of the heat dissipation airflow flows to the molecular sieve module 30 through the internal heat dissipation port 217, and after heating the internal molecular sieve, it is discharged to the outside through the internal heat dissipation port 217 and the external heat dissipation port 216. The nitrogen gas discharged from the molecular sieve module 30 is also discharged through the external heat dissipation port 216 after being silenced.

[0165] When the ambient temperature of the oxygen concentrator is low, such as in winter when the outside temperature is low, part of the heat dissipation airflow discharged from the compressor module 20 heats the molecular sieve module 30, enabling the molecular sieve module 30 to work efficiently in low-temperature environments. When the outside temperature is high, it is not necessary to heat the molecular sieve module 30. A movable or removable cover plate (not shown) is provided at the internal heat dissipation port 217 to close the internal heat dissipation port 217.

[0166] Referring to Figure 7, a gap a is provided between the oxygen storage tank 14 and the inner wall of the vertical frame 112, and the first region A is connected to the second region B through the gap a. The heat dissipation airflow can flow to the molecular sieve module 30 through the internal heat dissipation port 217 and the gap a, so as to perform temperature compensation and preheating of the molecular sieve module 30, thereby improving the working efficiency of the molecular sieve module 30.

[0167] In some embodiments of this application, the control component 12 includes a main control board, which integrates a display and detection unit and an electronic control unit.

[0168] The display and detection unit is responsible for touch operation and data acquisition, enabling users to monitor the oxygen generator's status in real time. Specifically, in this embodiment, a display screen is provided on the top of the upper frame 113, located above the main control board. The display screen is a touch screen, allowing users to more conveniently view equipment status information, such as oxygen concentration, temperature, pressure, and other important parameters, and to perform simple equipment control via touch.

[0169] The electrical control unit controls the operating parameters of the oxygen generator, such as the fan 13, compressor module 20, and molecular sieve module 30, to ensure the stable operation of the system under different working conditions.

[0170] In addition, the main control board is located in the heat dissipation duct of the upper rack. The airflow in the duct can carry away the heat generated by the main control board, which can effectively reduce the operating temperature of the main control board, thereby extending its service life and improving the stability and reliability of the system.

[0171] Referring to Figure 23, the main frame module 10 further includes an auxiliary oxygen storage tank 141. The auxiliary oxygen storage tank 141 is located inside the base portion 111 and is connected in series with the oxygen storage tank 14. The connection between the two can be achieved through a sealing gasket. The auxiliary oxygen storage tank 141 serves two purposes: firstly, it fully utilizes the space of the existing equipment structure to increase the gas storage effect; secondly, it can provide additional oxygen reserves to maintain the stability of the oxygen supply when the equipment load is high or the oxygen demand increases.

[0172] This dual oxygen storage design, through the coordinated operation of the oxygen storage tank 14 and the auxiliary oxygen storage tank 141, greatly enhances the continuous oxygen supply capacity of the oxygen generator and effectively reduces the problem of insufficient oxygen supply under high demand conditions. At the same time, placing the auxiliary oxygen storage tank 141 in the base 111 makes the equipment structure more compact and reasonable, and further improves the space utilization of the main frame module 10.

[0173] As shown in Figure 23, one end of the main control board is located above the oxygen storage tank 14. Since electronic components need to be installed on the main control board, a certain gap b is left between the top of the gas storage tank and the main control board. At the same time, the upper part of the molecular sieve module 30 is provided with an auxiliary air inlet. An auxiliary air inlet 38 (as shown in Figure 2) is opened on the outer shell of the molecular sieve module 30 and is connected to the auxiliary air inlet. The auxiliary air inlet is connected to the gap b, and a certain heat dissipation effect is achieved by using the auxiliary air inlet.

[0174] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by the present invention.
