Description

TECHNICAL FIELD

[0001] The utility model relates to oxygen -making equipment technical field especially relates to a modular oxygen generator. BACKGROUND

[0002] At present, the household oxygen generator mainly relies on the air compressor to compress air, and separates and extracts oxygen from air through the molecular sieve to provide relatively pure oxygen for household use. In the common product form of household oxygen generator, the molecular sieve tank and the air compressor are integrated as core components in the equipment. However, this integrated design has some shortcomings, especially the service life of the molecular sieve is crucial to the performance of the oxygen generator, once it is aged or fails, the user often needs to replace the whole equipment, which not only increases the use cost, but also limits the maintainability and sustainability of the equipment.

[0003] In the patent with publication number CN210656150U, an oxygen generator is disclosed, which has a detachable module that can be detached from the main body of the oxygen generator. The 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 detached from the main body of the oxygen generator, realizing individual replacement or maintenance. This design solves the problems of difficult maintenance and high use cost of the oxygen generator to some extent. However, in the above-mentioned scheme, the molecular sieve tank and the compressor share one detachable module, when it is necessary to replace the molecular sieve tank or the compressor individually, the whole module still needs to be detached, resulting in complicated disassembly and assembly operation, which is not convenient for users to carry out more detailed maintenance.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0096] The terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features. In the description of the utility model, unless otherwise stated, the meaning of "multiple" is two or more.

[0097] Referring to Figures 1-23 , some embodiments of the modular oxygen generator of the utility model. The modular oxygen generator of the utility model, its structural characteristics lie in the high degree of modularization and the convenient disassembly design, not only facilitate maintenance and replacement parts, but also greatly improve the use flexibility and portability of the oxygen generator.

[0098] As Figure 1 and Figure 2 shown, the oxygen generator of the embodiment is a modular oxygen generator, which comprises a main frame module 10 and various functional modules which can be disassembled with the main frame module 10, and the various functional modules comprise a compressor module 20, a molecular sieve module 30 and a battery module 40.

[0099] The main frame module 10 is the main part of the modular oxygen generator, mainly used for connecting and supporting various functional modules.

[0100] The compressor module 20 comprises a compressor housing assembly 21 and a compressor 22 arranged in the compressor housing assembly 21, and the compressor 22 sucks in and compresses the air outside to a certain pressure, providing necessary power and pressure conditions for the subsequent air separation process.

[0101] The molecular sieve module 30 is the core part of the oxygen generator for separating oxygen. It uses specific molecular sieve material to separate oxygen and nitrogen from compressed air by adsorption and desorption principle.

[0102] The battery module 40 provides power support for the entire oxygen generator. Usually high-performance lithium battery or rechargeable battery pack is adopted to ensure that the oxygen generator can still run continuously under power failure or mobile environment. The battery module 40 not only supplies power for the compressor 22, molecular sieve tank and other key components, but also ensures the portability and endurance of the oxygen generator, so that it is suitable for various scenes and user needs.

[0103] As shown in Figure 6 , the main frame module 10 includes a main support 11, an oxygen storage tank 14 arranged in the main support 11, and a control assembly 12. The main support 11 is a main support structure. The oxygen storage tank 14 is connected with the molecular sieve module 30 and is used for storing the generated oxygen. The control assembly 12 is used for electrically controlling the oxygen generator and is responsible for controlling the working process of the entire oxygen generator and the coordinated operation between the modules.

[0104] As shown in Figure 5 , the compressor module 20 is located on one side of the main support 11 and is slidably detachably connected with the main support 11 through a first detachable structure C1.

[0105] The molecular sieve module 30 is located on the other side of the main support 11 and is slidably detachably connected with the main support 11 through a second detachable structure C2.

[0106] The battery module 40 is located on the lower side of the main support 11 and is slidably detachably connected with the main support 11 through a third detachable structure.

[0107] The compressor module 20, the molecular sieve module 30, and the battery module 40 are respectively electrically connected with the main frame module 10 through an electrical connection socket structure. The electrical connection socket structure is not only simple in design, but also has the functions of quick connection and disconnection, ensuring that the electrical connection between the functional modules and the main frame module 10 is quick and stable.

[0108] As shown in Figure 7 , the main frame module 10 is provided with a compressor gas seat 191 that is connected with the gas outlet of the compressor module 20, and is also provided with a molecular sieve gas seat 192 that is connected with the gas inlet and outlet of the molecular sieve module 30. The compressor gas seat 191, the molecular sieve gas seat 192, and the oxygen storage tank 14 are connected in sequence through pipelines to realize gas path communication. After the compressor module 20 and the molecular sieve module 30 are slidably installed, quick connection can be realized through the compressor gas seat 191 and the molecular sieve gas seat 192. The compressor gas seat 191 and the molecular sieve gas seat 192 are connected with the oxygen storage tank 14 through pipelines, ensuring smooth flow of gas and efficient performance of the oxygen separation process.

[0109] The above-mentioned modular oxygen generator, through modular design, enables the compressor module 20, the molecular sieve module 30, and the battery module 40 to be independently installed and quickly detached, not only improving the independence of each functional module, but also greatly simplifying the maintenance and replacement operation of the oxygen generator. In actual use, when a module fails or needs to be replaced regularly, the user can replace the corresponding module according to the needs without the need for complex disassembly or repair of the entire device, not only reducing maintenance costs and downtime, but also improving the long-term stability of the oxygen generator.

[0110] In addition, the modular design also greatly improves the scalability and adaptability of the oxygen generator. Users can select different specifications of compressor modules 20, molecular sieve modules 30 and battery modules 40 according to actual needs, so as to flexibly adjust the functions of the equipment according to environmental changes or different use scenarios. For example, in a relatively static application scenario, users may need longer endurance, and can choose a larger capacity battery module 40; while in a situation requiring efficient oxygen supply, a larger power compressor module 20 and / or a more efficient molecular sieve module 30 may be selected. This highly flexible module selection allows the oxygen generator to be widely used in different fields such as home, hospital, field and emergency rescue.

[0111] In some embodiments of the present application, as Figure 4 One side of the main support 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, so that the compressor module 20 can be disassembled along the horizontal direction through the second sliding groove structure.

[0112] 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 sliding groove structure is provided between the side surface of the semi-open structure and the molecular sieve module 30, so that the molecular sieve module 30 can be disassembled along the vertical direction through the third sliding groove structure.

[0113] Specifically, the horizontal disassembly of the compressor module 20 and the molecular sieve module 30 with the main support 11 using the side opening structure and the vertical disassembly of the compressor module 20 and the molecular sieve module 30 with the main support 11 using the semi-open structure are considered:

[0114] The compressor is basically a horizontally placed structural component, which is more convenient to install horizontally. In addition, the compressor module 20 usually needs to be configured with a corresponding fan assembly and air inlet structure above it for heat dissipation and air intake of the compressor module 20, so it needs to have a certain equipment structure installation space above it. In addition, the compressor module 20 will vibrate during operation, so the clamping and horizontal placement of the side opening structure can effectively ensure the stability after installation.

[0115] The function and effect of the molecular sieve module 30 are mainly related to the size of the filled molecular sieve, that is, the more the molecular sieve is filled, the better the processing effect is. Therefore, the semi-open structure can greatly extend the length of the molecular sieve module 30. At the same time, the semi-open structure also facilitates the disassembly of the molecular sieve module as a whole. In addition, the accuracy and reliability of the molecular sieve module during gas path docking also need to be considered. The vertical installation method can avoid the influence of the decline of the docking accuracy caused by the weight of the molecular sieve itself, thereby improving the airtight effect.

[0116] Further, the installation and disassembly mode of the battery module 40 is designed based on the above-mentioned structure setting, and specifically as shown in Figure 3 The first sliding groove structure is arranged between the battery module 40 and the bottom surface of the main support 11, so that the battery module 40 can be disassembled along the horizontal direction.

[0117] The battery module 40 is installed at the bottom surface of the main support 11, which is convenient to install and disassemble quickly, and does not affect the compressor module 20 and the molecular sieve module 30 during disassembly.

[0118] 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 the 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 the compressor module 20 and the molecular sieve module 30.

[0119] This principle avoids the occurrence of leakage and gas leakage. After the battery module 40 is disassembled, all device components are in a power-off state, and the device will not run. At this time, it is very safe and reliable to disassemble the compressor module 20 and the molecular sieve module 30.

[0120] Specifically, referring to Figure 6 The main support 11 is composed of a base portion 111, a vertical support portion 112 and an upper support portion 113.

[0121] The base portion 111 is used to support the entire structure, the vertical support portion 112 is vertically arranged on the base portion 111, and the upper support portion 113 is connected to the top end of the vertical support portion 112 and located on one side thereof to form the top structure of the oxygen generator.

[0122] In order to realize the modular installation of the compressor module 20 and the molecular sieve module 30, as shown in Figure 4 A first area A is formed between the vertical support portion 112, the bottom surface of the upper support portion 113 and the base portion 111, and the first area A forms a side opening structure. The compressor module 20 is installed in the first area A. A second area B is formed between the other side of the vertical support portion 112 and the base portion 111, and the second area B forms a semi-open structure. The molecular sieve module 30 is installed in the second area B. The semi-open structure allows the molecular sieve module 30 to have a large volume and increase the oxygen production efficiency.

[0123] The oxygen storage tank 14 is vertically arranged in the vertical support portion 112 of the main support 11, so that the oxygen storage tank 14 can be compactly arranged in the main support 11 structure, saving the horizontal space of the device.

[0124] Further, referring to Figure 3And Figure 4 When assembling the oxygen generator, the compressor module 20 and the molecular sieve module 30 need to be assembled first, and then inserted into the main support 11. Among them, as shown in the direction, Figure 4 , the compressor module 20 moves to the right and is horizontally inserted into the first area A of the main support 11, and is fixed with the main support 11 through 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 support 11, and is fixed with the main support 11 through 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 with the main support 11 through the third disassembly mechanism.

[0125] 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, and the battery module 40 is first disassembled by sliding to the left. Then, when disassembling the compressor module 20, the locking state of the first disassembly structure C1 is released, and the compressor module 20 is dragged horizontally to the left; when disassembling the molecular sieve module 30, the locking state of the second disassembly structure C2 is released, and the molecular sieve module 30 is moved vertically upward.

[0126] By designing the above disassembly logic, the battery module 40 must be disassembled before the compressor module 20 and the molecular sieve module 30 are disassembled. This design prevents the battery module 40 from being misoperated or damaged when the compressor module 20 and the molecular sieve module 30 are disassembled, thereby improving the safety of the operation.

[0127] In the following part, the running path of the oxygen generating flow of the modular oxygen generator of the present application will be specifically explained.

[0128] Referring to Figure 8 , the upper shelf part 113 side of the main support 11 is provided with an air inlet 1131, and the top surface of the side opening structure is provided with an air outlet hole 1132. The external air enters through the air inlet 1131 and is discharged through the air outlet hole 1132, forming an oxygen generating flow.

[0129] Referring to Figure 10 , the top of the compressor housing assembly 21 is provided with an air inlet cavity 212 corresponding to the air outlet hole 1132, and the compressor housing assembly 21 is provided with a gas guide pipe (not shown). The air inlet cavity 212 introduces the oxygen generating flow into the compressor 22 through the gas guide pipe.

[0130] The inner side bottom of the side opening structure is provided with a compressor air receiving seat 191, as Figure 7 , that is, the compressor air receiving seat 191 is arranged at the bottom end of the vertical shelf part 112 of the main support 11. The compressor module 20 is arranged on the side surface of the inner side of the side opening structure. The compressor air outlet interface 213 is in communication with the compressor air outlet, and the compressor air outlet interface 213 is protrudingly arranged.

[0131] After the compressor module 20 is assembled in place along the horizontal direction, the compressor gas outlet interface 213 is inserted into the compressor gas seat 191 to achieve airtight connection.

[0132] The gas outlet end of the compressor gas seat 191 is communicated with the molecular sieve gas seat 192 through a pipeline.

[0133] Referring to Figure 7 , the molecular sieve gas seat 192 is arranged on the bottom surface of the semi-open structure, that is, the molecular sieve gas seat 192 is arranged on the base portion 111 of the main support 11. The molecular sieve gas seat 192 has an air inlet channel and an oxygen outlet channel, wherein the air inlet channel is communicated with the gas outlet end of the compressor gas seat 191 through a pipeline, and the oxygen outlet channel is connected with the oxygen storage tank 14 through a pipeline.

[0134] Referring to Figure 14 , the bottom of the molecular sieve module 30 is provided with a molecular sieve air inlet interface 34 and a molecular sieve oxygen outlet interface 35, and the molecular sieve air inlet interface 34 and the molecular sieve oxygen outlet interface 35 are arranged protruding.

[0135] After the molecular sieve module 30 is assembled in place along the vertical direction downward, the molecular sieve air inlet interface 34 and the molecular sieve oxygen outlet interface 35 are inserted into the air inlet channel and the oxygen outlet channel in the molecular sieve gas seat 192 respectively to achieve airtight connection.

[0144] In the following part, the sliding and dismounting structure of the compressor module 20 will be described in detail.

[0145] In some embodiments of the present application, the compressor module 20 and the top surface of the base portion 111 are connected by a second sliding groove structure horizontally. That is, the compressor module 20 is installed and dismounted along the horizontal direction.

[0146] Specifically, as Figure 7 and Figure 11As shown, the second sliding groove structure includes at least two second clamping groove limit members 1113, which are respectively arranged on the top surface of the base portion 111, and the two second clamping groove limit members 1113 are oppositely arranged. The bottom two opposite sides of the compressor module 20 are provided with downward extending limit rails 211, and the compressor module 20 can slide along the second clamping groove limit members 1113 through the limit rails 211. The limit rails 211 are preferably arranged outside the second clamping groove limit members 1113. The second sliding groove structure not only plays a sliding guide role of the compressor module 20, but also limits other displacement of the compressor module 20 in the horizontal direction. As for the displacement of the compressor module 20 in the upward and downward directions, it is limited by the structure of the main support 11.

[0147] In some embodiments of the present application, the first dismounting structure C1 includes a filter cavity opening 215 arranged on the bottom of the compressor module 20, a main support opening 1118 arranged on the main support 11, and a cover 1104.

[0148] The filter cavity opening 215 is communicated with a filter cavity located in the compressor module 20 for filtering the air inlet of the compressor 22. The filter cavity can be provided with filter cotton.

[0149] The cover 1104 is arranged at the filter cavity opening 215 in a detachable manner, and is used to open or close the filter cavity.

[0150] The main support opening 1118 is arranged on the main support 11, and the opening size is matched with the cover 1104, so that the cover 1104 is dismounted or installed through the main support opening 1118.

[0151] The cover 1104 has a cover extension 11041, which at least partially extends into the main support opening 1118, so as to limit the sliding movement between the compressor module 20 and the main support 11.

[0152] During installation, the compressor module 20 is installed into the side opening structure of the main support 11 along the sliding direction, and when installed in place, the filter cavity opening 215 is positioned corresponding to the main support opening 1118, and then the cover 1104 is installed through the main support opening 1118, the filter cavity opening 215 is closed through the cover 1104, and the compressor shell assembly 21 and the main support 11 are limited. During dismounting, the cover 1104 is dismounted through the main support opening 1118, the position limitation of the cover 1104 on the compressor shell assembly 21 and the main support 11 is released, and then the compressor module 20 is dismounted from the side opening structure.

[0153] Further, the first dismounting structure C1 further comprises a limiting connecting piece, which is arranged 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 dismounted for cleaning or replacement of the filter cotton, the limiting connecting piece can ensure stable connection of the compressor module 20 and the main support 11. In some embodiments, the limiting connecting piece is a quick-release bolt.

[0154] In some other embodiments of the present application, as shown in Figure 11 the limiting connecting piece is a compressor button 23 arranged on the compressor module 20, and the main support 11 is provided with a limiting through hole 1117 into which the compressor button 23 is inserted to be locked.

[0155] As shown in Figure 7 the limiting through hole 1117 is arranged through the base portion 111 of the main support 11. The compressor button 23 is arranged on the bottom of the compressor module 20. The compressor button 23 is inserted into the limiting through hole 1117 to be locked. When pressed, the compressor button 23 moves upward to exit the limiting through hole 1117, thereby releasing the locking state of the compressor button 23 and the limiting through hole 1117.

[0156] Further, the first dismounting structure C1 further comprises a spring (not shown) connected with the compressor button 23 for keeping the compressor button 23 in the locked state and resetting after being pressed.

[0157] Through the first dismounting structure C1, when dismounting the compressor module 20, the user only needs to dismount the cover 1104 and then press the compressor button 23 to easily take out the compressor module 20.

[0158] Since the compressor button 23 is arranged in the base portion 111, when the battery module 40 is dismounted, the cover 1104 can be dismounted through the main support opening 1118 first, and then the compressor button 23 is pressed through the limiting through hole 1117 to realize quick dismounting of the compressor module 20.

[0159] In the following part, the sliding and dismounting structure of the molecular sieve module 30 will be described in detail.

[0160] In some embodiments of the present application, the molecular sieve module 30 and the side surface of the vertical support portion 112 are vertically slidably connected through a third sliding groove structure. That is, the molecular sieve module 30 is installed and dismounted in the vertical direction.

[0161] Specifically, as shown in Figure 6 and Figure 14As shown, the third sliding groove structure includes at least two third clamping groove limit members 1121, which are respectively arranged on the side surfaces of the vertical frame part 112, and the two third clamping groove limit members 1121 are oppositely arranged to form a sliding groove. The side surface of the molecular sieve module 30 is provided with a third sliding part 31, which is slidably installed in the sliding groove and is clamped with the third clamping groove limit member 1121, for limiting the displacement of the molecular sieve module 30 in the vertical direction (horizontal direction) perpendicular to the sliding direction.

[0162] During installation, the operator only needs to vertically slide the molecular sieve module 30 along the third sliding groove structure to quickly reach the approximate installation position, greatly reducing the adjustment time and difficulty during installation. The second dismounting structure C2 can quickly and firmly fix the molecular sieve module 30 on the main support 11 after the molecular sieve module 30 is slid into position, completing the installation process. During dismounting, the locking state of the second dismounting structure C2 is first released, and then the molecular sieve module 30 is slid out along the third sliding groove structure.

[0163] In some embodiments of the present application, as shown in Figure 12 and Figure 13 The second dismounting structure C2 includes a locking groove 32 arranged on the bottom surface of the molecular sieve module 30, a locking member 15 arranged on the base part 111 of the main support 11, and a molecular sieve key 16.

[0164] The locking member 15 and the molecular sieve key 16 are movably arranged on the main support 11. Specifically, a molecular sieve key mounting hole 1115 for mounting the molecular sieve key 16 is formed on the bottom surface of the base part 111, and the molecular sieve key 16 is slidably arranged in the molecular sieve key mounting hole 1115. The locking member 15 is locked with the molecular sieve module 30 after cooperating with the locking groove 32 by moving, and is unlocked after exiting the locking groove 32. In this embodiment, the mounting and dismounting direction of the molecular sieve module 30 is arranged vertically to the movable direction of the locking member 15.

[0165] Through the arrangement of the second dismounting structure C2, the molecular sieve module 30 only needs to be aligned with the main support 11 and moved to position along the mounting and dismounting direction, and then the locking member 15 is pushed to be inserted into the locking groove 32 to complete the locking. At the same time, the mounting and dismounting direction of the molecular sieve module 30 is arranged vertically to the movable direction of the locking member 15, so that the locking and cooperation stability of the locking member 15 and the locking groove 32 is high, and the shaking gap of the molecular sieve module 30 after installation is reduced.

[0166] Since the molecular sieve key 16 is arranged on the bottom surface of the base part 111, when the battery module 40 is dismounted, the molecular sieve module 30 can be quickly dismounted by pressing the molecular sieve key 16.

[0167] In some embodiments of the present application, as shown in Figures 14-16As shown, the second dismounting structure C2 includes the engaging claw 33 arranged on the bottom surface of the molecular sieve module 30, the card hole 1114 arranged on the base portion 111 and matched with the engaging claw 33, and the molecular sieve button 17 for releasing the engaging state of the engaging claw 33 and the card hole 1114.

[0168] The engaging claw 33 is arranged in the direction of the installation of the molecular sieve module 30, that is, the engaging claw 33 is arranged vertically. The dismounting direction of the molecular sieve module 30 is parallel to the moving direction of the molecular sieve button 17 when the molecular sieve button 17 is released.

[0169] Through the second dismounting structure C2, the user only needs to press the molecular sieve button 17 when dismounting the molecular sieve module 30, so as to easily take out the molecular sieve module 30, and the whole process does not need complex tools and professional maintenance skills, which greatly reduces the operation difficulty. In addition, the structure is simple 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 generator, and is conducive to reducing the failure.

[0170] In the embodiment, the base portion 111 is provided with a molecular sieve button mounting hole 1116 for mounting the molecular sieve button 17. Since the molecular sieve button 17 is arranged on the bottom surface of the base portion 111, when the battery module 40 is dismounted, the molecular sieve module 30 can be quickly dismounted by pressing the molecular sieve button 17.

[0171] In some other embodiments of the present application, as shown in Figure 17 and Figure 18 The second dismounting structure C2 includes the molecular sieve fastener 18 arranged on the bottom of the main support 11 and the fastening hole 37 arranged on the molecular sieve module 30, and the fastening hole 37 is matched with the molecular sieve fastener 18. The rotating locking structure is adopted between the fastening hole 37 and the molecular sieve fastener 18, which can be set as a threaded hole for the fastening hole 37 and a matched external thread on the upper end of the molecular sieve fastener 18.

[0172] The molecular sieve fastener 18 is arranged vertically, and the via hole is arranged vertically and is used for the molecular sieve fastener 18 to pass through the gas seat 192. The molecular sieve fastener 18 passes through the gas seat, which is conducive to the stability of the molecular sieve gas inlet interface 34 and the molecular sieve oxygen outlet interface 35 after the molecular sieve module 30 is installed and fixed to the molecular sieve gas seat 192, and avoids the problem of gas leakage and other problems affecting the normal operation of the equipment due to unstable connection of the molecular sieve gas inlet interface 34 and the molecular sieve oxygen outlet interface 35.

[0173] The molecular sieve fastener 18 has a fastening column 181 and a handle 182 at the lower end of the fastening column 181. The base portion 111 has a receiving groove 1119 at the lower end for accommodating the handle 182. The handle 182 is provided with a space for placement by the receiving groove 1119, so that the structure is 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 is then fastened into the fastening hole 37; so that the installation path of the molecular sieve fastener 18 is smooth, which facilitates the installation operation in a reasonable order and ensures that the entire connection and fixing process can be completed efficiently and accurately.

[0174] In the following part, the sliding and dismounting structure of the battery module 40 will be described in detail.

[0175] In some embodiments of the present application, referring to Figure 6 and Figures 19-22 , the first sliding groove structure includes at least two first clamping groove limiters 1112 arranged on the bottom surface of the base portion 111. The two first clamping groove limiters 1112 are oppositely arranged 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 is clamped with the first clamping groove limiters 1112 to limit the displacement of the battery module 40 in the direction perpendicular to the sliding direction. The design of the double-limiting piece and sliding groove structure effectively improves the stability of the sliding connection of the battery module 40, and avoids the inclination or shaking of the battery module 40 due to external force, so that the installation of the battery module 40 is more stable and reliable.

[0176] In some embodiments of the present application, as shown in Figure 22 , the third dismounting structure includes a limiting clamping groove 1111 arranged on the bottom surface of the main support 11 and a quick release assembly 43 arranged on the battery module 40.

[0177] The battery module 40 includes a battery module shell 41 and a battery assembly 42 arranged in the battery module shell 41. The quick release assembly 43 is installed in the battery module shell 41.

[0178] As shown in Figure 21 , the quick release assembly 43 includes a battery key 431 and a clamping piece 432. As shown in Figure 22 , the clamping piece 432 is clamped with the limiting clamping groove 1111 to limit the displacement of the battery module 40 in the sliding direction. The battery key 431 is configured to drive the clamping piece 432 to move, so that the clamping piece 432 is withdrawn from the limiting clamping groove 1111, thereby releasing the clamping state of the clamping piece 432 and the limiting clamping groove 1111.

[0179] 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.

[0180] 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.

[0181] 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.

[0182] See Figure 6 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 away from the limiting slot 1111 through the interaction between the force-applying surface f and the receiving surface h.

[0183] 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.

[0184] The following sections will describe in detail the airflow path of the heat dissipation system in the modular oxygen generator of this application.

[0185] In some embodiments of the present application, as shown in Figure 8 and Figure 10 To dissipate heat from the compressor module 20, the upper shelf portion 113 of the main support 11 is provided with an air outlet 1133 on the bottom surface and the top surface of the side opening structure. A fan 13 is arranged in the upper shelf 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.

[0186] The air flow entering through the air inlet 1131 and being discharged through the air outlet 1133 forms a heat dissipation air flow. The top portion 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 heat dissipation air flow flows into the compressor housing assembly 21 through the air inlet area 214 to dissipate heat from the internal compressor 22.

[0187] That is, in the present embodiment, the external air entering through the air inlet 1131 is partially discharged through the air outlet 1133 to form an oxygen production air flow and partially discharged through the air outlet 1133 to form a heat dissipation air flow.

[0188] The heat dissipation air flow entering the internal compressor module 20 dissipates heat from 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.

[0189] Specifically, as shown in Figure 11 and Figure 7 , the compressor housing assembly 21 is provided with an external heat dissipation opening 216 and an internal heat dissipation opening 217. Part of the heat dissipation air flow is output to the outside through the external heat dissipation opening 216. Part of the heat dissipation air flow flows to the molecular sieve module 30 through the internal heat dissipation opening 217, heats the internal molecular sieve, and is then discharged to the outside through the internal heat dissipation opening 217 and the external heat dissipation opening 216. The nitrogen gas discharged from the molecular sieve module 30 is also discharged through the external heat dissipation opening 216 after being subjected to noise reduction treatment.

[0190] When the oxygen generator is in an environment with a low temperature, such as in winter, the external temperature is low, and part of the heat dissipation air flow 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 external temperature is high, the molecular sieve module 30 does not need to be heated, and a movable or detachable cover plate (not shown) is arranged at the internal heat dissipation opening 217 to close the internal heat dissipation opening 217.

[0191] Referring to Figure 23The oxygen storage tank 14 and the inner wall of the vertical frame part 112 are provided with a gap a, and the first area A is communicated with 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, so as to compensate and preheat the molecular sieve module 30, and improve the working efficiency of the molecular sieve module 30.

[0192] In some embodiments of the present application, the control assembly 12 comprises a main control board which integrates a display and detection unit and an electric control unit.

[0193] The display and detection unit is responsible for touch operation and data acquisition, so that the user can monitor the state of the oxygen concentrator in real time. Specifically, in the present embodiment, a display screen is arranged at the top of the upper frame part 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 state information such as oxygen concentration, temperature, pressure and other important parameters through the display screen, and can realize simple device control through touch.

[0194] The electric control unit realizes control of the operating parameters of the oxygen concentrator, such as electrical control of the fan 13, the compressor module 20 and the molecular sieve module 30, to ensure stable operation of the system under different working conditions.

[0195] In addition, the main control board is arranged in the heat dissipation air duct of the upper frame part, and the heat generated by the main control board can be taken away by the air flow in the air duct, so that the working temperature of the main control board can be effectively reduced, thereby prolonging the service life of the main control board and improving the stability and reliability of the system.

[0196] Referring to Figure 23 The main frame module 10 is further provided with an auxiliary oxygen storage tank 141, which is arranged inside the base part 111 and is in series communication with the oxygen storage tank 14. The connection between the two can be communicated through a sealing rubber pad. The auxiliary oxygen storage tank 141 can not only make full use of the space of the existing structure of the device to increase the gas storage effect, but also can provide additional oxygen reserve under the condition of high load of the device or increased oxygen demand, so as to maintain the stability of oxygen supply.

[0197] This double oxygen storage design greatly enhances the continuous oxygen supply capacity of the oxygen concentrator through the linkage work of the oxygen storage tank 14 and the auxiliary oxygen storage tank 141, effectively reduces the problem of insufficient oxygen supply of the device under high demand. At the same time, the auxiliary oxygen storage tank 141 is arranged in the base part 111, so that the structure of the device is more compact and reasonable, and the space utilization rate of the main frame module 10 is further improved.

[0198] As Figure 2As shown, one end of the main control board is located above the oxygen storage tank 14, and since electronic components need to be installed on the main control board, a certain gap b is left between the top of the gas 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 channel, and an auxiliary air inlet 38 (as shown in ​ ) is opened on the outer shell of the molecular sieve module 30 and communicates with the auxiliary air inlet channel. The auxiliary air inlet channel communicates with the gap b, and a certain heat dissipation effect is achieved by using the auxiliary air inlet channel.

[0199] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it. Although the present application has been described in detail with reference to the foregoing examples, those skilled in the art can still modify the technical solutions recorded in the foregoing examples, or make equivalent substitutions for some of the technical features. These modifications or substitutions do not cause the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by the present application.
