[0016] This utility model relates to an oxygen concentrator housing assembly. Using a base assembly as a supporting foundation, most of the pipes and wiring can be distributed on and above the base assembly, thus reducing the need for piping on the front housing and base assemblies. Even when piping is installed on the front housing and base assemblies, it can be achieved using detachable pipe joints. The front housing assembly can be first connected and fixed to the corresponding position on the base assembly. Then, the rear housing assembly is inserted into the front housing assembly via a guide groove and connected and fixed to the base assembly.

Detailed Implementation

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0028] Figure 1 This is a schematic diagram of the structure of the oxygen generator housing assembly according to a preferred embodiment of the present invention; Figure 2 This is a structural schematic diagram of the left side plate (right side plate) of a preferred embodiment of this utility model; Figure 3 This is a schematic diagram of the structure of the first-stage base of a preferred embodiment of the present invention; Figure 4 This is a schematic diagram of the structure of the second-level base of a preferred embodiment of the present invention; Figure 5 This is a schematic diagram of the base assembly of a preferred embodiment of the present invention; Figure 6 This is a schematic diagram of the structure of a dual-bottle oxygen concentrator according to a preferred embodiment of the present invention.

[0029] like Figure 1As shown, the oxygen concentrator housing assembly of this embodiment includes: a base assembly 100, which serves as a bottom support base and covers the bottom of the oxygen concentrator; a front shell assembly 200, which is vertically fixedly positioned on the base assembly 100 and covers the front side of the oxygen concentrator; and a rear shell assembly 300, which is vertically guided and inserted into the front shell assembly 200 and fixedly positioned on the base assembly 100, and covers the upper, front, left, right and rear sides of the oxygen concentrator. This utility model relates to an oxygen concentrator housing assembly. Using a base assembly 100 as a supporting foundation, most of the pipes and wiring can be distributed on and above the base assembly 100, thereby reducing the need for piping on the front housing assembly 200 and the base assembly 100. Even if piping is laid on the front housing assembly 200 and the base assembly 100, it can be achieved by using detachable pipe joints. Therefore, the front housing assembly 200 can be first connected and fixed to the corresponding position on the base assembly 100, and then the rear housing assembly 300 can be inserted into the front housing assembly 200 via a guide groove and connected and fixed to the base. On component 100, the guide insertion of the front shell component 200 and the rear shell component 300, along with their respective positioning connections to the base component 100, ensures structural stability after assembly. Furthermore, the internal structure of the oxygen concentrator can be displayed by disassembling the rear shell component 300, facilitating targeted maintenance, repair, and replacement. The oxygen concentrator's shell components allow for quick assembly and disassembly; of course, the front shell component 200 can also be disassembled separately. This simplifies the maintenance process, reduces maintenance time and labor intensity, and improves equipment maintainability. The oxygen concentrator shell component uses the base component 100 as the supporting foundation for the layout and positioning connections of the shell and internal structure. A rational layout on the base component 100 not only meets the functional requirements of a dual-bottle oxygen concentrator but also effectively reduces the overall volume, improves space utilization, and facilitates simplified maintenance procedures. The shell component design effectively solves the technical problems of disassembly, assembly, and space optimization in existing oxygen concentrators, enhancing user experience and equipment performance.

[0030] like Figure 1As shown, in this embodiment, the front shell assembly 200 includes a front shell 201, and front shell guide plates 202 are provided on both sides of the front shell 201. The front shell guide plates 202 are used to guide and insert with the rear shell assembly 300 in the vertical direction. The front shell guide plates 202 provide precise assembly guidance for the rear shell assembly 300. Through the vertical guide and insertion engagement, the rear shell assembly 300 can be quickly and accurately positioned and inserted into the front shell assembly 202 along the front shell guide plates 202, ensuring high alignment accuracy between the two during assembly and avoiding problems such as structural loosening or poor sealing caused by assembly deviations. This improves the assembly stability and reliability of the overall shell assembly. The design of the front shell guide plates 202 makes the installation process of the rear shell assembly 300 more intuitive and convenient. Assembly personnel only need to insert the rear shell assembly 300 along the guide plate to complete the initial positioning, eliminating the need for complex alignment operations, which greatly simplifies the assembly process, reduces assembly difficulty and time costs, and improves production efficiency. Since the front shell guide plate 202 provides a clear disassembly direction, the rear shell assembly 300 can be quickly removed from the front shell assembly 200, which not only facilitates the maintenance and repair of the oxygen generator's interior, but also allows for quick replacement of the rear shell assembly 300 when needed, further improving the maintainability of the equipment. The insertion and engagement of the front shell guide plate 202 and the rear shell assembly 300 not only serves as a guide during assembly, but also forms a strong integrated shell structure through its fixed connection with the base assembly 100. This structural design effectively disperses external impact forces, enhances the overall strength and durability of the oxygen concentrator casing, and extends the equipment's service life. The design of the front shell guide plate 202 allows the rear shell assembly 300 to fit tightly against the front shell assembly 200, reducing assembly gaps between casing components and further optimizing the overall volume of the oxygen concentrator. This compact design not only meets the functional requirements of a dual-bottle oxygen concentrator but also effectively reduces the footprint of the oxygen concentrator, improving space utilization. The front shell guide plate 202 in the front shell assembly 200, through its vertical guide insertion with the rear shell assembly 300, not only ensures assembly accuracy and stability but also simplifies the assembly and disassembly process, enhances the overall structural integrity, and optimizes space utilization. This design significantly improves the performance of the oxygen concentrator casing components and solves the problems of complex assembly, inconvenient maintenance, and large size in existing technologies.

[0031] like Figure 1As shown, in this embodiment, the front shell guide plates 202 on both sides of the front shell 201 are arranged symmetrically from left to right, or the front shell guide plates 202 on both sides of the front shell 201 are arranged in a staggered manner from left to right. When the front shell guide plates 202 are arranged symmetrically from left to right, they can provide uniform support and guidance for the rear shell assembly 300. This symmetrical design makes the rear shell assembly 300 more evenly stressed during assembly, and can be inserted into the front shell assembly 200 more accurately along the guide plates, thereby improving the assembly accuracy and stability. The symmetrical arrangement of the front shell guide plates 202 can make the entire shell assembly more balanced when subjected to force, reducing shaking or deformation caused by structural asymmetry. This balance is particularly important for equipment such as oxygen concentrators that need to operate stably for a long time, and can effectively extend the service life of the equipment.

[0032] Symmetrical layouts are generally easier to implement because they allow the use of the same molds or processing techniques to manufacture the front shell guide plate 202, which not only reduces manufacturing costs but also improves production efficiency. Left-right symmetrical layouts are suitable for scenarios requiring high assembly precision and structural balance, improving assembly stability and simplifying design and manufacturing processes. When the front shell guide plate 202 is staggered left-right, it can be adjusted according to the specific layout and shape of the internal components of the oxygen concentrator. This staggered design better adapts to complex internal structures, optimizes space utilization, and further reduces the overall volume of the oxygen concentrator. The staggered front shell guide plate 202 provides a more flexible assembly path for the rear shell assembly 300. This flexibility allows the rear shell assembly 300 to avoid other internal components during assembly, reducing interference during the assembly process. The staggered front shell guide plate 202 can also provide a more reasonable layout for the internal heat dissipation channels of the oxygen concentrator. By adjusting the staggered position of the guide plate, the airflow path can be optimized, improving heat dissipation efficiency. Left-right staggered layout: Suitable for scenarios with complex internal structures or high space utilization requirements, it optimizes spatial layout, enhances structural flexibility, and improves heat dissipation efficiency. Regardless of the layout method, the design of the front shell guide plate 202 significantly improves the performance of the oxygen concentrator housing components, solving the problems of complex assembly, inconvenient maintenance, and large size in existing technologies. This flexible design provides a better solution for the diverse needs of oxygen concentrators.

[0033] like Figure 1As shown, in this embodiment, the front housing 201 is also equipped with a flow meter 203, a flow regulating component 204, and a humidification bottle mounting cavity 205. The humidification bottle mounting cavity 205 contains a humidification bottle adapter 206 for fixing and positioning the humidification bottle 400 and for connecting with the humidification bottle 400. The humidification bottle adapter 206 is sequentially connected to the flow meter 203 and the flow regulating component 204. The integration of the flow meter 203, flow regulating component 204, and humidification bottle mounting cavity 205 on the front housing 201 achieves a centralized layout of functional components, reduces the complexity of the internal piping arrangement of the oxygen concentrator, optimizes space utilization, and makes the entire oxygen concentrator structure more compact and smaller in size. The integrated design of the flow meter 203 and flow regulating component 204 allows users to intuitively observe the oxygen flow rate and conveniently adjust the flow rate, improving operational convenience. Users can quickly adjust the oxygen output flow rate without additional tools. The humidification bottle mounting cavity 205 contains a humidification bottle adapter 206 for fixing and positioning the humidification bottle 400 and for connecting with the humidification bottle 400. The 00 adapter connection not only ensures the stable installation of the humidification bottle, but also enables oxygen humidification through the humidification bottle adapter 206, avoiding the irritation of the respiratory tract by dry oxygen. The humidification bottle adapter 206 is sequentially connected to the flow meter 203 and the flow regulating component 204, forming a stable oxygen delivery and regulation system. This not only ensures precise control of the oxygen flow rate, but also improves the quality of oxygen through humidification, enhancing the stability and safety of the entire oxygen generator system. The integrated design makes the disassembly and installation of the flow meter, flow regulating component, and humidification bottle more convenient, facilitating daily maintenance and cleaning, and reducing equipment maintenance costs. Preferably, the humidification bottle installation cavity 205 is equipped with two sets of humidification bottle adapters 206 and two sets of humidification bottles 400, with each set of humidification bottles 400 connected to a flow meter 203 and a flow regulating component 204.

[0034] like Figure 1 As shown in this embodiment, the front shell 201 is also provided with a nebulizer port 207. The nebulizer port 207 allows connection to a nebulizer device, which atomizes the medication into fine particles through the airflow generated by the oxygen concentrator, allowing it to enter the respiratory tract and lungs in aerosol form, thereby achieving a local therapeutic effect. This nebulization inhalation therapy can be effectively used to treat respiratory diseases such as bronchial asthma, bronchiectasis, and lung infections. The design of the nebulizer port 207 enables the oxygen concentrator to have a nebulization function, allowing users to perform nebulization therapy at home without going to a hospital or clinic. This design is particularly suitable for the elderly and children because nebulization inhalation requires less inspiratory capacity from the patient. Integrating the nebulization function into the oxygen concentrator reduces the need to purchase an additional nebulizer, saving space and cost. This integrated design makes the device more compact and suitable for home use. The nebulizer port 207 enhances the versatility of the oxygen concentrator, enabling it to not only provide oxygen but also meet the user's needs in the treatment of respiratory diseases, improving the practicality and cost-effectiveness of the device.

[0035] like Figure 1 and Figure 2As shown, in this embodiment, the rear shell assembly 300 includes a left side panel 301, a top panel 302, a right side panel 303, and a rear side panel 304. At least one of the left side panel 301, the top panel 302, the right side panel 303, and the rear side panel 304 is provided with an air intake filter window 305. The left side panel 301 and the right side panel 303 are provided with guide grooves 306 for vertically guiding and inserting with the front shell assembly 200. The design of the guide groove 306 makes the installation process of the rear shell assembly 300 more intuitive and convenient. Assemblers only need to insert the rear shell assembly 300 along the guide groove into the front shell assembly 200 to complete the initial positioning, eliminating the need for complex alignment operations. This greatly simplifies the assembly process, reduces assembly difficulty and time costs, and improves production efficiency. Similar to the assembly process, the rear shell assembly 300 can be quickly disassembled via the guide groove 306, facilitating maintenance and repair of the oxygen concentrator's interior. This not only improves the maintainability of the equipment but also reduces maintenance costs. Air intake filter windows 305 are installed on the left side plate 301, top plate 302, right side plate 303, or rear side plate 304 to effectively filter the air entering the oxygen concentrator, reducing dust and impurities from contaminating internal components and extending the equipment's lifespan. Simultaneously, a reasonable air intake layout optimizes the airflow path and improves heat dissipation efficiency. By installing air intake filter windows 305 on multiple plates, the design can be optimized according to the oxygen concentrator's internal heat dissipation requirements and airflow characteristics. This design not only meets heat dissipation needs but also improves the quality of the equipment's operating environment through filtration. Optionally, the front shell guide plate 202 and the guide groove 306 are matched; specifically, the positions are matched and they are plugged in.The matching insertion design of the guide groove 306 and the front shell guide plate 202 provides a clear assembly path for the rear shell assembly 300. This precise guidance ensures that the rear shell assembly 300 can be quickly aligned and accurately inserted with the front shell assembly 200 in the vertical direction, avoiding assembly deviations and improving assembly accuracy. Through the matching insertion of the guide groove 306 and the front shell guide plate 202, a tight connection is formed between the rear shell assembly 300 and the front shell assembly 200, enhancing the structural stability of the overall shell assembly and effectively reducing loosening caused by vibration or external forces, thus extending the service life of the equipment. The matching position of the front shell guide plate 202 and the guide groove 306 allows the rear shell assembly 300 to be flexibly installed according to the specific layout inside the oxygen concentrator. The adjustable design allows it to adapt to different models or functions of oxygen concentrators, enhancing the product's versatility and adaptability. Through a matching plug-in design, a tight connection can be formed between the front shell guide plate 202 and the guide groove 306, ensuring that the equipment performance will not be affected by loosening or wear during long-term use. This reliability is especially important for equipment like oxygen concentrators that require long-term stable operation. The matching plug-in design between the guide groove 306 and the front shell guide plate 202 allows the rear shell assembly 300 to fit tightly against the front shell assembly 200, reducing assembly gaps and further optimizing the overall size of the oxygen concentrator. This compact design not only meets the functional requirements of a dual-bottle oxygen concentrator but also effectively reduces the footprint of the oxygen concentrator, improving space utilization.

[0036] like Figure 1 and Figure 2As shown, in this embodiment, the top panel 302 has a window 307 for exposing the display panel 500. The window 307 exposes the display panel 500, allowing users to directly access crucial information such as equipment operating status, oxygen flow rate, and operating time. Users can also perform operations and adjustments, such as flow rate adjustment and mode switching. This intuitive interface enhances the user experience and makes the equipment more user-friendly. The exposed display panel 500 provides users with a clear view of the equipment's real-time status, reducing misoperation due to unclear information and improving the safety and reliability of the equipment. By creating the window 307 on the top panel 302, the display panel 500 can be integrated into the rear housing component 300, rather than protruding or occupying external space. This results in a more compact overall structure for the oxygen concentrator, reducing its footprint while maintaining good functionality and aesthetics. The window 307 design integrates the display panel 500 with the rear housing component 300, improving the overall appearance and making it more suitable for home environments. While the display panel 500 is exposed through the window 307, its main body remains within the rear housing component. Inside the rear housing assembly 300, protected by the top panel 302, the display panel 500 is effectively protected from external physical impacts, dust contamination, or liquid splashes, extending its service life. The design of the window 307 allows for a sealing structure around the display panel 500, further enhancing the equipment's airtightness, preventing dust and moisture from entering, and improving the equipment's reliability in complex environments. Since the display panel 500 is integrated inside the rear housing assembly 300 and exposed through the window 307, maintenance or replacement of the display panel 500 can be quickly completed by simply disassembling the rear housing assembly 300, simplifying the maintenance process and reducing repair costs. The integrated design of the display panel 500 and the rear housing assembly 300 increases the modularity of the equipment, facilitating standardized assembly and quality control during production. The window 307 design allows the display panel 500 to work better with other functional components of the oxygen concentrator (such as flow regulation components and humidification bottles). This integrated design not only improves the overall performance of the equipment but also enhances its intelligence level.

[0037] like Figure 1 and Figure 2As shown, in this embodiment, the left side panel 301, top panel 302, right side panel 303, and rear side panel 304 adopt an integrally molded structure. The integral molding design eliminates structural weaknesses caused by connection points or seams, giving the rear shell assembly 300 higher overall strength and stability, effectively resisting external impacts and deformation during long-term use, and extending the service life of the equipment. It reduces potential problems caused by loose or aging connectors, further improving the reliability of the equipment. Reducing seams and connection points lowers the possibility of dust, impurities, and moisture entering the interior, better protecting internal components, and improving the sealing and protective performance of the equipment, especially suitable for scenarios with high environmental adaptability requirements. It makes the appearance of the rear shell assembly 300 simpler and smoother, without obvious seams or connectors, improving the overall aesthetics of the equipment, especially suitable for home environments, and better integrating into the user's home decoration. Since no additional connectors or complex assembly steps are required, the integral molding design can significantly reduce assembly time and costs in the production process, and improve production efficiency. The left side panel 301, top panel 302, right side panel 303, and rear side panel 304 are detachably connected and fixed. This detachable design allows each part of the rear housing assembly 300 to be individually disassembled and replaced, facilitating maintenance, cleaning, or upgrades of internal components, significantly improving maintainability and reducing maintenance costs and time. When a part is damaged, only the damaged part needs to be replaced, eliminating the need to replace the entire rear housing assembly, further improving the equipment's economic efficiency. The detachable design allows for adjustments to the rear housing assembly 300 according to different needs or functional expansions. For example, different side panels or top panels can be selected based on the specific model or functional requirements of the oxygen concentrator, enhancing the product's versatility and adaptability. This design also facilitates modular assembly during production, improving production flexibility and efficiency. The detachable design allows the rear housing assembly 300 to be disassembled into multiple parts for transportation and storage, reducing the equipment's size and weight, lowering transportation costs and storage space requirements. At the installation site, users can quickly assemble the equipment as needed, improving ease of use. Users can personalize or adjust the rear housing assembly 300 according to their needs or preferences, enhancing user satisfaction and experience. The unibody design is suitable for scenarios with high requirements for structural strength, sealing, and aesthetic design, significantly improving equipment stability and reliability while reducing assembly time and costs. The detachable connection design is suitable for scenarios with high requirements for ease of maintenance, flexibility, and convenient transportation and storage, improving maintainability and economy while enhancing the user experience. Both design approaches have their advantages, and the specific choice should be weighed and decided based on the actual usage needs and application scenarios of the oxygen concentrator.

[0038] like Figure 1 , Figure 3 , Figure 4and Figure 5As shown, in this embodiment, the base assembly 100 includes a first-stage base 101 and a second-stage base 102, with the first-stage base 101 connected and fixed to the second-stage base 102. The first-stage base 101 is provided with a clearance groove 1011, a rear shell guide groove 1012, a rear shell fixing post 1013, an adsorption tower positioning post 1014, a first heat dissipation port group 1015, a compressor mounting position 1016, and a fan holder 1017. The second-stage base 102 is provided with a filter mounting chamber 1021, a second heat dissipation structure 1022, and a reinforcing structure 1023. The clearance groove 1011 is correspondingly arranged with the filter mounting chamber 1021. The first heat dissipation port group 1015 is distributed around the fan holder 1017 and located in the area where the compressor mounting position 1016 is located. The first heat dissipation port group 1015 is correspondingly arranged with the second heat dissipation structure 1022. The rear shell guide groove 1012 and the rear shell fixing post 1013 are respectively correspondingly arranged with the rear shell assembly 300. The layered design and connection fixation, with the first-stage base 101 connected and fixed to the second-stage base 102, allows the base assembly 100 to withstand greater weight and pressure while providing higher structural stability. This design is particularly suitable for high-power, high-flow oxygen concentrators, effectively supporting the weight of internal components. The reinforcing structure 1023 on the second-stage base 102 further enhances the rigidity and deformation resistance of the base, ensuring that the equipment will not be damaged by vibration or external forces during long-term operation. The synergistic effect of the heat dissipation vents and the heat dissipation structure, with the first heat dissipation vents 1015 on the first-stage base 101 distributed around the fan holder 1017 and located in the area of ​​the compressor mounting position 1016, allows the fan to directly dissipate heat from the compressor area. Simultaneously, the first heat dissipation vents 1015 and the second heat dissipation structure 1022 on the second-stage base 102 are correspondingly arranged, further... The optimized heat dissipation path improves heat dissipation efficiency. Through a rational layout of the heat dissipation vents and structures, the base assembly 100 effectively and quickly dissipates heat generated by the compressor and fan, preventing heat accumulation and extending the equipment's lifespan while enhancing operational stability. The compact layout design, with the clearance slot 1011 on the first-stage base 101 corresponding to the filter mounting compartment 1021 on the second-stage base 102, allows for a compact filter installation inside the base, reducing space waste. Furthermore, the rational layout of structures such as the adsorption tower positioning column 1014, compressor mounting position 1016, and fan holder 1017 further optimizes the space utilization of the base assembly 100, resulting in a smaller overall size for the oxygen concentrator. The integrated functionality of the base assembly 100, incorporating multiple functional structures such as heat dissipation vents, mounting positions, and positioning columns, reduces the need for external connectors, making the equipment more compact and suitable for home use.The positioning and fixing of the rear shell assembly: The rear shell guide groove 1012 and the rear shell fixing post 1013 on the first-stage base 101 are respectively arranged corresponding to the rear shell assembly 300. This design provides a clear assembly path and fixing points for the rear shell assembly 300, making the installation and disassembly of the rear shell assembly more convenient and quick. It not only simplifies the assembly process but also facilitates the maintenance and replacement of internal components. Modular design: The layered base design allows the base assembly 100 to be assembled in modules, reducing production costs and facilitating the quick replacement of damaged modules during maintenance, thus improving the maintainability of the equipment. Clear functional zoning: The design of the base assembly 100 clearly categorizes functions such as heat dissipation, filtration, and installation, enabling each functional module to operate efficiently. For example, the filter installation chamber 1021 can effectively filter the air entering the oxygen generator, reducing dust and impurities from contaminating internal components, while the heat dissipation structure ensures that the equipment will not be damaged by overheating during high-load operation. Extended equipment lifespan: By optimizing heat dissipation and filtration functions, the base assembly 100 can effectively reduce the wear and failure rate of internal components, thereby extending the service life of the equipment and reducing user operating costs. The design of the base assembly 100, including the first-stage base 101 and the second-stage base 102, as well as various functional structures thereon, significantly enhances the structural stability, heat dissipation performance, and space utilization efficiency of the oxygen concentrator. Simultaneously, this design simplifies assembly and maintenance processes, improves the overall performance and service life of the equipment, and through rational layout and functional integration, the base assembly 100 provides a solid foundation for the efficient operation of the oxygen concentrator.
