Description

Technical Field

[0001] The present invention relates to the technical field of oxygen production equipment, and in particular to a modular oxygen production machine. Background Art

[0002] At present, household oxygen concentrators mainly rely on air compressors to compress air, and separate and extract oxygen from the air through molecular sieves to provide relatively pure oxygen for household use. In the common product form of household oxygen concentrators, the molecular sieve tank and air compressor are core components, which are integrated inside the device. However, this integrated design has some shortcomings, especially the service life 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 the cost of use, but also limits the maintainability and sustainability of the equipment.

[0003] In the patent with publication number CN210656150U, an oxygen concentrator is disclosed, which has a detachable module that can be removed from the main body of the oxygen concentrator. This design integrates the compressor and the molecular sieve tank in the detachable module, so that when the molecular sieve tank or the compressor needs to be replaced or maintained, the detachable module can be removed from the main body of the oxygen concentrator to achieve separate replacement or maintenance. This design solves the problems of difficult maintenance and high cost of use of the oxygen concentrator to a certain extent. However, in the above scheme, since the molecular sieve tank and the compressor share a detachable module, when the molecular sieve tank or the compressor needs to be replaced separately, the entire module still needs to be disassembled, resulting in cumbersome disassembly and assembly operations, which is inconvenient for users to perform more sophisticated maintenance.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0032] Reference Figure 1-Figure 23 , which are some embodiments of the modular oxygen concentrator of the present invention. The modular oxygen concentrator of the present invention has the structural characteristics of high modularity and convenient assembly and disassembly design, which is not only convenient for maintenance and replacement of parts, but also greatly improves the flexibility and portability of the oxygen concentrator.

[0033] like Figure 1 and Figure 2 As shown, the oxygen concentrator of this embodiment is a modular oxygen concentrator, including a main frame module 10, and various functional modules that can be disassembled and assembled with the main frame module 10, and each functional module includes a compressor module 20, a molecular sieve module 30 and a battery module 40.

[0034] The main frame module 10 is the main part of the modular oxygen concentrator and is mainly used to connect and support various functional modules.

[0035] The compressor module 20 includes a compressor housing assembly 21 and a compressor 22 disposed in the compressor housing assembly 21. The compressor 22 sucks in external air and compresses it to a certain pressure, thereby providing necessary power and pressure conditions for the subsequent air separation process.

[0036] The molecular sieve module 30 is the core part of the oxygen generator for oxygen separation. It uses specific molecular sieve materials to separate oxygen and nitrogen from compressed air through the principle of adsorption and desorption.

[0037] The battery module 40 provides power support for the entire oxygen concentrator. High-performance lithium batteries or rechargeable battery packs are usually used to ensure that the oxygen concentrator can continue to operate in a power outage or mobile environment. The battery module 40 not only powers key components such as the compressor 22 and the molecular sieve tank, but also ensures the portability and endurance of the oxygen concentrator, making it suitable for a variety of scenarios and user needs.

[0038] Among them, Figure 6 As shown, the main frame module 10 includes a main frame 11, an oxygen storage tank 14 arranged in the main frame 11, and a control component 12. The main frame 11 is the main supporting structure. The oxygen storage tank 14 is connected to the molecular sieve module 30 for storing the produced oxygen. The control component 12 is used to electrically control the oxygen generator, and is responsible for controlling the entire oxygen generator workflow and the coordinated operation between the various modules.

[0039] See also Figure 5 The compressor module 20 is located on one side of the main support 11 and is slidably and detachably connected to the main support 11 via a first disassembly structure C1.

[0040] The molecular sieve module 30 is located on the other side of the main support 11 and is slidably and detachably connected to the main support 11 via a second disassembly structure C2.

[0041] The battery module 40 is located at the lower side of the main bracket 11 and is slidably and detachably connected to the main bracket 11 via a third disassembly structure.

[0042] The compressor module 20, the molecular sieve module 30 and the battery module 40 are electrically connected to the main frame module 10 through the electrical socket structure. The electrical socket structure is not only simple in design, but also has the function of quick connection and disconnection, ensuring that the electrical connection between each functional module and the main frame module 10 is quick and stable.

[0043] like Figure 7The main frame module 10 is provided with a compressor air receiving seat 191 that is connected to the air outlet of the compressor module 20, and a molecular sieve air receiving seat 192 that is connected to the air inlet and outlet of the molecular sieve module 30. The compressor air receiving seat 191, the molecular sieve air receiving seat 192, and the oxygen storage tank 14 are connected in sequence through pipelines to achieve gas communication. After the compressor module 20 and the molecular sieve module 30 are slidably installed, they can be quickly connected through the compressor air receiving seat 191 and the molecular sieve air receiving seat 192. The compressor air receiving seat 191 and the molecular sieve air receiving seat 192 are then connected to the oxygen storage tank 14 through pipelines, ensuring the smooth flow of gas and the efficient oxygen separation process.

[0044] The modular oxygen concentrator described above, through modular design, allows the compressor module 20, the molecular sieve module 30 and the battery module 40 to be independently installed and quickly disassembled, which 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 fails or needs to be replaced regularly, the user can replace the corresponding module separately according to needs without the need for complex disassembly or repair of the entire device, which not only reduces maintenance costs and downtime, but also improves the long-term stability of the oxygen concentrator.

[0045] In addition, the modular design has greatly improved the scalability and adaptability of the oxygen concentrator. Users can choose compressor modules 20, molecular sieve modules 30 and battery modules 40 of different specifications according to actual needs, so as to flexibly adjust the functions of the equipment according to environmental changes or different usage scenarios. For example, in a more static application scenario, the user may need a longer battery life and can choose a larger capacity battery module 40; in situations where efficient oxygen supply is required, it may be necessary to choose a higher power 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 different fields such as homes, hospitals, the wild, and emergency rescue.

[0046] In some embodiments of the present application, Figure 4 One side of the main bracket 11 is a side opening structure, and a second slide groove structure is provided between the upper end and / or the lower end of the side opening structure and the compressor module 20, so that the compressor module 20 can be disassembled and assembled in the horizontal direction through the second slide groove structure.

[0047] The other side of the main support 11 is a semi-open structure, and the molecular sieve module 30 is arranged in the semi-open structure. A third slide groove structure is provided between the side of the semi-open structure and the molecular sieve module 30, and the molecular sieve module 30 can be disassembled and assembled along the vertical direction through the third slide groove structure.

[0048] Specifically, the compressor module 20 and the molecular sieve module 30 are respectively disassembled horizontally with the main support 11 using a side opening structure and vertically with the main support 11 using a semi-open structure in consideration of: The compressor is basically a horizontally placed structural component, which is more convenient to install horizontally. At the same time, under normal circumstances, a corresponding fan assembly and air intake structure need to be configured above the compressor module 20 for heat dissipation and air intake of the compressor module 20. Therefore, a certain equipment structure installation space is required above it, and the compressor module 20 will vibrate during operation. Therefore, the embedding and horizontal placement of the side opening structure can effectively ensure its stability after installation.

[0049] The functional effect of the molecular sieve module 30 is mainly related to the amount of molecular sieve filled, that is, the more molecular sieve is filled, the better the treatment effect. Therefore, the length of the molecular sieve module 30 can be greatly extended by cooperating with the semi-open structure. At the same time, the semi-open structure is also convenient for the overall disassembly and assembly of the molecular sieve module at a later stage. Another point that needs to be considered is the accuracy and reliability of the molecular sieve module during gas path docking. Compared with other forms, the longitudinal installation method can avoid the influence of the decrease in docking accuracy due to the weight of the molecular sieve itself, thereby improving the airtight effect.

[0050] Furthermore, based on the above-mentioned structure, the installation and removal methods of the battery module 40 are designed, as shown in the following figure. Figure 3 As shown, a first slide groove structure is provided between the battery module 40 and the bottom surface of the main bracket 11, and the battery module 40 can be disassembled and assembled in a horizontal direction through the first slide groove structure.

[0051] The battery module 40 is installed on the bottom surface of the main bracket 11. Firstly, its installation is relatively convenient and can be quickly disassembled, and the compressor module 20 and the molecular sieve module 30 will not be affected during the disassembly process; secondly, corresponding logical design is carried out for the disassembly steps to reduce the occurrence of risks in the equipment.

[0052] Specifically, when the battery module 40 is not disassembled, the first disassembly structure C1 and the second disassembly structure C2 are in a locked state to ensure a stable 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 to allow the user to freely disassemble and assemble the compressor module 20 and the molecular sieve module 30.

[0053] This avoids the occurrence of leakage of electricity and gas in principle. After the battery module 40 is disassembled, the components of the entire device are in a power-off state and the device will not operate. At this time, it is very safe and reliable to disassemble and assemble the compressor module 20 and the molecular sieve module 30.

[0054] Specifically, see Figure 6The main support 11 is composed of a base portion 111 , a vertical frame portion 112 and an upper frame portion 113 .

[0055] The base portion 111 is used to support the entire structure, the vertical frame portion 112 is vertically disposed on the base portion 111, and the upper frame portion 113 is connected to the top of the vertical frame portion 112 and is located on one side thereof to form the top structure of the oxygen concentrator.

[0056] In order to realize the modular installation of the compressor module 20 and the molecular sieve module 30, as shown in FIG. Figure 4 As shown, a first area A is formed between one side of the vertical frame 112, the bottom surface of the upper frame 113 and the base 111, and the first area A forms a side opening structure, and the compressor module 20 is installed in the first area A. A second area B is formed between the other side of the vertical frame 112 and the base 111, and the second area B forms a semi-open structure, and the molecular sieve module 30 is installed in the second area B. The semi-open structure can make the molecular sieve module 30 larger in size and increase the oxygen production efficiency.

[0057] The oxygen storage tank 14 is vertically arranged in the vertical frame portion 112 of the main frame 11, so that the oxygen storage tank 14 can be compactly arranged in the structure of the main frame 11, saving the lateral space of the equipment.

[0058] Further, see Figure 3 and Figure 4 When assembling the oxygen concentrator, the compressor module 20 and the molecular sieve module 30 need to be assembled first, and then inserted into the main bracket 11. Figure 4 In the direction shown, the compressor module 20 moves to the right and is horizontally inserted into the first area A of the main bracket 11, and is fixed to the main bracket 11 by the first disassembly structure C1; the molecular sieve module 30 is pressed from top to bottom into the second area B on the right side of the main bracket 11, and is fixed to the main bracket 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 bracket 11 and is fixed to the main bracket 11 by the third disassembly mechanism.

[0059] Similarly, when disassembling the compressor module 20 and the molecular sieve module 30, it is necessary to release the locking state of the third disassembly mechanism, first slide to the left to disassemble the battery module 40, and 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.

[0060] By designing the above disassembly and assembly logic, the battery module 40 must be disassembled before disassembling the compressor module 20 and the molecular sieve module 30. This design prevents the battery module 40 from being misoperated or damaged when disassembling the compressor module 20 and the molecular sieve module 30, thereby improving the safety of operation.

[0061] In the following section, the operation path of the oxygen production air flow of the modular oxygen concentrator of the present application will be described in detail.

[0078] In the following section, the sliding and disassembly structure of the compressor module 20 will be described in detail.

[0079] In some embodiments of the present 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.

[0080] Specifically, Figure 7 and Fig.11 As shown, the second slide groove structure includes at least two second slot limiters 1113, which are respectively arranged on the top surface of the base portion 111, and the two second slot limiters 1113 are arranged opposite to each other. The two opposite sides of the bottom of the compressor module 20 are provided with limit edges 211 extending downward, and the compressor module 20 can slide along the second slot limiter 1113 through the limit edges 211. The limit edges 211 are preferably arranged on the outside of the second slot limiter 1113. The second slide groove structure not only plays a role in sliding guidance of the compressor module 20, but also limits other displacements of the compressor module 20 in the horizontal direction. As for the displacement of the compressor module 20 in the up and down directions, it is limited by the structure of the main bracket 11.

[0081] In some embodiments of the present application, the first disassembly structure C1 includes a filter cavity opening 215 opened at the bottom of the compressor module 20 , a main frame opening 1118 opened at the main frame 11 , and a cover body 1104 .

[0082] The filter cavity opening 215 is connected to a filter cavity located in the compressor module 20 and used for filtering the air intake of the compressor 22. Filter cotton can be placed in the filter cavity.

[0083] The cover 1104 is detachably disposed at the filter cavity opening 215 for opening or closing the filter cavity.

[0084] The main frame opening 1118 is opened on the main frame 11 , and the opening size thereof is adapted to the cover body 1104 , so that the cover body 1104 can be disassembled or installed through the main frame opening 1118 .

[0085] The cover 1104 has a cover extension portion 11041 , and the cover extension portion 11041 at least partially extends into the main frame opening 1118 to limit the sliding movement between the compressor module 20 and the main support 11 .

[0086] During installation, the compressor module 20 is installed into the side opening structure of the main support 11 along the sliding direction. When installed in place, the filter cavity opening 215 corresponds to the position of the main frame opening 1118, and then the cover body 1104 is installed through the main frame opening 1118. The filter cavity opening 215 is closed by the cover body 1104, and the compressor housing assembly 21 and the main support 11 are limited. During disassembly, the cover body 1104 is first disassembled through the main frame opening 1118 to release the position restriction of the cover body 1104 on the compressor housing assembly 21 and the main support 11, and then the compressor module 20 is removed from the side opening structure.

[0087] 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 disassembled to clean or replace the filter cotton, the limiting connector can ensure that the compressor module 20 and the main support 11 are stably connected. In some embodiments, the limiting connector is a quick-release bolt.

[0088] In other embodiments of the present application, Fig.11 As shown, the limiting connecting piece is a compressor button 23, and the compressor button 23 is arranged on the compressor module 20; a limiting through hole 1117 is provided on the main bracket 11, and the compressor button 23 is inserted into the limiting through hole 1117 to be locked.

[0089] like Figure 7 As shown, the limiting through hole 1117 is provided on the base portion 111 of the main bracket 11 so as to pass through from top to bottom. The compressor button 23 is provided 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 to exit the limiting through hole 1117, thereby releasing the locking state between the compressor button 23 and the limiting through hole 1117.

[0090] Furthermore, the first disassembly structure C1 further includes a spring (not shown), which is connected to the compressor button 23 and is used to keep the compressor button 23 in a locked state and reset after being pressed.

[0091] Through the first disassembly structure C1, when the user disassembles the compressor module 20, he only needs to remove the cover 1104 and then press the compressor button 23 to easily take out the compressor module 20.

[0092] Since the compressor button 23 is disposed in the base portion 111 , after the battery module 40 is disassembled, the cover body 1104 can be disassembled through the main frame opening 1118 , and then the compressor button 23 can be pressed through the limiting through hole 1117 to realize the quick disassembly of the compressor module 20 .

[0093] In the following section, the sliding and disassembly structure of the molecular sieve module 30 will be described in detail.

[0094] In some embodiments of the present application, the molecular sieve module 30 is vertically slidably connected to the side of the vertical frame portion 112 via a third slide groove structure, that is, the molecular sieve module 30 is installed and removed along the vertical direction.

[0095] Specifically, Figure 6 and Fig.14 As shown, the third chute structure includes at least two third slot stoppers 1121, which are respectively arranged on the side of the vertical frame portion 112, and the two third slot stoppers 1121 are arranged opposite to each other to form a chute. A third sliding portion 31 is provided on the side of the molecular sieve module 30, and the third sliding portion 31 is slidably installed in the chute and mutually engaged with the third slot stopper 1121 to limit the displacement of the molecular sieve module 30 in a direction perpendicular to the sliding direction (horizontal direction).

[0096] During installation, the operator only needs to slide the molecular sieve module 30 vertically along the third chute structure to quickly reach the approximate installation position of the molecular sieve module 30, greatly reducing the adjustment time and difficulty during the installation process. After the molecular sieve module 30 slides into place, the second disassembly structure C2 can quickly and firmly fix it on the main bracket 11 to complete the installation process. During disassembly, first release the locking state of the second disassembly structure C2, and then slide the molecular sieve module 30 out along the third chute structure.

[0097] In some embodiments of the present application, Fig.12 and Fig.13 As shown, the second disassembly structure C2 includes a locking groove 32 provided on the bottom surface of the molecular sieve module 30 , a locking piece 15 provided on the base portion 111 of the main support 11 , and a molecular sieve button 16 .

[0098] The locking member 15 and the molecular sieve button 16 are movably arranged on the main bracket 11. Specifically, a molecular sieve button installation hole 1115 for installing the molecular sieve button 16 is provided on the bottom surface of the base portion 111, and the molecular sieve button 16 is slidably arranged in the molecular sieve button installation hole 1115. The locking member 15 is moved to lock the molecular sieve module 30 after cooperating with the locking groove 32, and is unlocked after exiting the locking groove 32. In this embodiment, the loading and unloading direction of the molecular sieve module 30 is perpendicular to the movable direction of the locking member 15.

[0099] By setting the second disassembly structure C2, it is only necessary to align the molecular sieve module 30 with the main bracket 11 and move it into place along the loading and unloading direction, and then push the locking piece 15 to insert it 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 piece 15, so that the locking cooperation between the locking piece 15 and the locking groove 32 is highly stable, thereby reducing the shaking gap of the molecular sieve module 30 after installation.

[0100] Since the molecular sieve button 16 is disposed on the bottom surface of the base portion 111 , when the battery module 40 is disassembled, the molecular sieve module 30 can be quickly disassembled by pressing the molecular sieve button 16 .

[0101] In some other embodiments of the present application, Figure 14-16 As shown, the second disassembly structure C2 includes a locking claw 33 provided on the bottom surface of the molecular sieve module 30, a bayonet 1114 provided on the base portion 111 and matching the locking claw 33, and a molecular sieve button 17 for releasing the locking state of the locking claw 33 and the bayonet 1114.

[0102] The engaging claw 33 is extended along the installation direction of the molecular sieve module 30, that is, the engaging claw 33 is arranged up and down. The loading and unloading direction of the molecular sieve module 30 is arranged parallel to the moving direction of the molecular sieve button 17 when the engagement is released.

[0103] Through the second disassembly structure C2, when the user disassembles the molecular sieve module 30, he only needs to press the molecular sieve button 17 to easily remove the molecular sieve module 30. The whole process does not require complicated tools and professional maintenance skills, which greatly reduces the difficulty of operation. In addition, the structure is simple to set and the movement mode is clear, which ensures the reliability of the locking and unlocking functions of the molecular sieve module 30 during the use of the oxygen concentrator, which is conducive to reducing failures.

[0104] In this embodiment, a molecular sieve button installation hole 1116 for installing the molecular sieve button 17 is opened on the base portion 111. Since the molecular sieve button 17 is arranged on the bottom surface of the base portion 111, when the battery module 40 is disassembled, the molecular sieve module 30 can be quickly disassembled by pressing the molecular sieve button 17.

[0105] In some other embodiments of the present application, Fig.17 and Fig.18 As shown, the second disassembly structure C2 includes a molecular sieve fastener 18 provided at the bottom of the main support 11, and a fastening hole 37 provided on the molecular sieve module 30, and 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, and the fastening hole 37 can be set to be a threaded hole, and the upper end of the molecular sieve fastener 18 is matched with an external thread.

[0106] The molecular sieve fastener 18 is arranged up and down, and a through hole is provided on the molecular sieve air receiving seat 192, which is used for the molecular sieve fastener 18 to pass through. The molecular sieve fastener 18 passes through the air receiving seat, which is beneficial to the stability of the molecular sieve air inlet interface 34 and the molecular sieve oxygen outlet interface 35 after the molecular sieve module 30 is installed and fixed, and is inserted into the molecular sieve air receiving seat 192, thereby avoiding gas leakage caused by unstable connection between the molecular sieve air inlet interface 34 and the molecular sieve oxygen outlet interface 35, which affects the normal operation of the equipment.

[0107] The molecular sieve fastener 18 has a fastening column 181, a handle 182 located at the lower end of the fastening column 181, and a receiving groove 1119 for receiving the handle 182 is provided at the lower end of the base portion 111. The receiving groove 1119 is provided to provide a placement space for the handle 182, making the structure more compact and reasonable. A connecting hole is provided between the through hole and the receiving groove 1119, and the through hole and the 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 then is fastened to the fastening hole 37; so that the penetration path of the molecular sieve fastener 18 is smooth, which is conducive to the installation operation in a reasonable order, and ensures that the entire connection and fixing process can be completed efficiently and accurately.

[0108] In the following section, the sliding and disassembly structure of the battery module 40 will be described in detail.

[0109] In some embodiments of the present application, see Figure 6 and Fig.19 The first slide groove structure includes at least two first slot limiters 1112, which are respectively arranged on the bottom surface of the base portion 111. The two first slot limiters 1112 are arranged relative to each other to form a slide groove. The battery module 40 is provided with a sliding portion 411, which can be slidably installed in the slide groove and engage with the first slot limiter 1112 to limit the displacement of the battery module 40 in a direction perpendicular to the sliding direction. The design of this double limiter and slide groove structure effectively improves the stability of the sliding connection of the battery module 40, while avoiding the tilting or shaking of the battery module 40 caused by external force, so that the installation of the battery module 40 is more stable and reliable.

[0110] In some embodiments of the present application, Figure 20-22As shown, the third disassembly structure includes a limiting slot 1111 arranged on the bottom surface of the main bracket 11 and a quick release assembly 43 arranged on the battery module 40.

[0111] The battery module 40 includes a battery module housing 41 and a battery assembly 42 disposed in the battery module housing 41. A quick release assembly 43 is installed in the battery module housing 41.

[0112] like Fig. 22 As shown, the quick release assembly 43 includes a battery button 431 and a buckle 432. Fig.21 As shown, the latch 432 is engaged 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 latch 432 to move so that the latch 432 withdraws from the limiting slot 1111, thereby releasing the engagement state between the latch 432 and the limiting slot 1111.

[0113] Specifically, the buckle 432 slides in a direction perpendicular to the sliding direction of the battery module 40 and is disposed in the battery module housing 41. The battery module housing 41 is provided with a through hole 412 opposite to the limiting slot 1111, and the buckle 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 buckle 432, and the buckle 432 is driven to exit the limiting slot 1111 by pressing the battery button 431, thereby completing the quick release operation of the battery module 40.

[0114] The battery module housing 41 is provided with a battery button mounting hole 413, and the battery button 431 is mounted in the battery button mounting hole 413, and the pressing direction of the battery button 431 is perpendicular to the sliding direction of the buckle 432. In this embodiment, the battery button 431 is mounted 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, so that external force can be applied to the battery button 431.

[0115] Furthermore, the quick release assembly 43 also includes an elastic member 433, which is connected to the buckle member 432, and is used to maintain the buckle member 432 in the engaged state with the limit slot 1111 when the battery button 431 is not pressed, and to automatically reset the buckle member 432 after the battery button 431 is released. The introduction of the elastic member 433 greatly improves the operational safety and convenience of the quick release assembly 43, and can be restored to the initial state without additional steps after the user completes the operation, thereby avoiding the problem of the battery module 40 not being properly locked due to improper operation.

[0116] See also Fig. 22The battery button 431 is designed to include a battery button body 4311 and a force-applying portion 4312 protruding from the battery button body 4311. The force-applying portion 4312 has an inclined force-applying slope f. The buckle 432 has a receiving surface h that matches the force-applying slope f. The battery button 431 drives the buckle 432 to move in a direction away from the limiting slot 1111 through the interaction between the force-applying slope f and the receiving surface h.

[0117] In some embodiments of the present application, the quick-release assembly 43 further includes a mounting seat 434, which is fixedly connected to the battery module housing 41, and the buckle 432 and the battery button 431 are both slidably disposed on the mounting seat 434. The mounting seat 434 provides a stable working platform for the buckle 432 and the battery button 431. At the same time, the buckle 432 and the battery button 431 can be assembled before the mounting seat 434, and then integrally mounted on the battery module housing 41, thereby improving assembly and disassembly efficiency.

[0118] In the following section, the operation path of the heat dissipation airflow of the modular oxygen concentrator of the present application will be described in detail.

[0119] In some embodiments of the present application, Figure 6 and Figure 8 As shown, in order to dissipate the heat of the compressor module 20, an air outlet 1133 is provided on the bottom surface of the upper frame 113 of the main bracket 11 and the top surface of the side opening structure, and a fan 13 is provided in the upper frame 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.

[0120] The airflow entering through the air inlet 1131 and discharged through the air outlet 1133 forms a heat dissipation airflow. The top of the compressor housing assembly 21 is provided with an air inlet area 214 corresponding to the air outlet 1133. Fig.10 The heat dissipation air flows through the air inlet area 214 and flows into the compressor housing assembly 21 to dissipate heat for the internal compressor 22 .

[0121] That is, in this embodiment, part of the external air entering through the air inlet 1131 is discharged through the air outlet 1132 to form the oxygen-generating airflow, and part of the external air is discharged through the air outlet 1133 to form the heat-dissipating airflow.

[0122] The heat dissipation airflow entering the compressor module 20 dissipates heat for 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 for heating the internal molecular sieve.

[0123] Specifically, Fig.10 and Fig.11As shown, an external heat dissipation port 216 and an internal heat dissipation port 217 are provided on the compressor housing assembly 21. Part of the heat dissipation gas flows through the external heat dissipation port 216 and is output to the outside; part of the heat dissipation gas flows through the internal heat dissipation port 217 and flows to the molecular sieve module 30, heats the internal molecular sieve, and then is discharged to the outside through the internal heat dissipation port 217 and the external heat dissipation port 216. The nitrogen discharged from the molecular sieve module 30 is also discharged through the external heat dissipation port 216 after being silenced.

[0124] 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, so that the molecular sieve module 30 can work efficiently in a low temperature environment. When the outside temperature is high, the molecular sieve module 30 does not need to be heated, and a movable or detachable cover (not shown) is provided at the internal heat dissipation port 217 to close the internal heat dissipation port 217.

[0125] See also Figure 7 A gap a is provided between the oxygen storage tank 14 and the inner wall of the vertical frame portion 112, and the first area A is connected to the second area 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, and the molecular sieve module 30 is temperature compensated and preheated, thereby improving the working efficiency of the molecular sieve module 30.

[0126] In some embodiments of the present application, the control component 12 includes a main control board, which integrates a display and detection unit and an electronic control unit.

[0127] The display and detection unit is responsible for touch operation and data collection, so that the user can monitor the status of the oxygen concentrator in real time. Specifically, in this embodiment, a display screen is provided on the top of the upper shelf 113, and the display screen is located above the main control board. The display screen is a touch screen, and the user can more conveniently view the device status information, such as oxygen concentration, temperature, pressure and other important parameters through the display screen, and can realize simple device control through touch.

[0128] The electronic control unit controls the operating parameters of the oxygen generator, such as electrically controlling the fan 13, the compressor module 20, and the molecular sieve module 30, to ensure stable operation of the system under different working conditions.

[0129] In addition, the main control board is arranged in the heat dissipation duct of the upper frame, and the air flow in the duct can be used to take 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.

[0130] See also Fig.23The main frame module 10 is further provided with an auxiliary oxygen storage tank 141, which is arranged inside the base portion 111 and connected in series with the oxygen storage tank 14. The connection between the two can be connected through a sealing rubber pad. The auxiliary oxygen storage tank 141 firstly makes full use of the space of the existing structure of the equipment to increase the gas storage effect, and secondly, it can provide additional oxygen reserves to maintain the stability of oxygen supply when the equipment load is high or the oxygen demand increases.

[0131] This dual oxygen storage design greatly enhances the continuous oxygen supply capacity of the oxygen generator through the linkage of the oxygen storage tank 14 and the auxiliary oxygen storage tank 141, and effectively reduces the problem of insufficient oxygen supply of the equipment under high demand conditions. At the same time, the auxiliary oxygen storage tank 141 is arranged on the base portion 111, making the equipment structure more compact and reasonable, and further improving the space utilization rate of the main frame module 10.

[0132] like Fig.23 As shown, 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 oxygen storage tank and the main control board. At the same time, an auxiliary air inlet duct is provided on the upper part of the molecular sieve module 30, and an auxiliary air inlet 38 (such as Figure 2 ), which is connected to the auxiliary air inlet duct, and the auxiliary air inlet duct is connected to the gap b, so as to achieve a certain heat dissipation effect by utilizing the auxiliary air inlet duct.

[0133] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
