Description

Technical Field

[0001] This application belongs to the field of oxygen generator technology, specifically relating to an air outlet module used in oxygen generator equipment. Background Technology

[0002] As people's demand for indoor air quality and health increases, the application scenarios of oxygen generators have gradually expanded from the traditional medical field to civilian spaces such as offices, conference rooms, and homes. In scenarios with relatively dense crowds, such as conference rooms and open-plan offices, the need to supplement oxygen with oxygen generators to improve air freshness and alleviate fatigue from prolonged sitting is particularly prominent. The core requirements for oxygen generators in these civilian scenarios are not only oxygen supply efficiency, but also the need for their air outlet structure to have good installation flexibility. The air outlet structure needs to be adaptable to the layout characteristics of different spaces, such as under desktops, in wall corners, or next to office partitions, while also allowing for concealed installation to avoid occupying limited space. Simultaneously, it needs to be easy for ordinary users to install or adjust without the need for professional tools.

[0003] However, existing oxygen generators generally suffer from insufficient installation flexibility and weak adaptability to various scenarios, making it difficult to meet the usage needs of the aforementioned civilian applications. Specifically, the air outlet structure of most existing oxygen generators is directly fixed to the main body of the device, extending only to a limited area around the device via a short-distance pipeline. This makes independent and flexible installation based on the layout of the actual usage scenario impossible. This not only makes operation cumbersome but may also damage the installation surface. Furthermore, some air outlet modules designed to improve installation stability suffer from structural redundancy and excessive size, easily occupying floor or wall space after installation, contradicting the compact, aesthetically pleasing, and practical requirements of scenarios such as conference rooms. Conversely, simplifying the structure to reduce size leads to decreased compatibility with different specifications of oxygen delivery pipes, further limiting its versatility in multiple scenarios. Utility Model Content

[0004] This application provides an air outlet module for oxygen generators to solve the technical problems of installation difficulties in civilian scenarios such as offices and conference rooms caused by the limited installation of the air outlet end of traditional oxygen generators.

[0005] The technical solution adopted in this application is as follows:

[0006] An air outlet module for use in an oxygen generator includes a housing. The housing has an air inlet connected to an oxygen delivery pipe of the oxygen generator, an air outlet for outputting oxygen, and a mounting part that can be connected to a mounting surface. The housing is provided with a transition structure. One end of the transition structure is connected to the air inlet to receive oxygen delivered by the oxygen delivery pipe, and the other end is connected to the air outlet to guide the oxygen to be output from the air outlet.

[0007] The air outlet module described in this application also includes the following additional technical features:

[0008] The adapter structure includes an outlet pipe and an adjusting component; one end of the outlet pipe is connected to the inlet to receive oxygen delivered by the oxygen delivery pipe, and the adjusting component is movably installed on the outlet pipe and can move relative to the outlet pipe to adjust the amount and angle of oxygen output from the adapter structure to the outlet.

[0009] The vent pipe is provided with a first vent hole facing the vent outlet, and the adjusting member is provided with a second vent hole. The adjusting member can rotate relative to the vent pipe to adjust the alignment area of ​​the first vent hole and the second vent hole. When the first vent hole and the second vent hole are completely misaligned, the adjusting member blocks the first vent hole.

[0010] The adjusting component is constructed as an adjusting tube sleeved on the air outlet pipe, with the inner wall of the adjusting tube fitting against the outer wall of the air outlet pipe. The adjusting tube rotates circumferentially around the air outlet pipe to adjust the relative position of the second air outlet and the first air outlet.

[0011] The regulating tube is provided with a toggle ring edge located on the periphery of the second air outlet, and the toggle ring edge is at least partially located inside the air outlet.

[0012] The outlet pipe includes a first section and a second section that are interconnected. The first section is connected to the oxygen supply pipe of the oxygen generating device. The outer diameter of the first section is larger than the outer diameter of the second section. The connection between the first section and the second section has an abutting boss. The regulating pipe abuts against the abutting boss.

[0013] The venting module further includes a sealing end located on the side of the second section away from the first section. The sealing end abuts against the side wall of the regulating pipe. The housing also includes a mounting platform located inside the housing. The mounting platform has a mounting groove, and the sealing end has a mounting protrusion located within the mounting groove.

[0014] The housing includes an upper housing and a lower housing, which are detachably connected by bolts. The adapter structure is detachably connected to the oxygen delivery pipe of the oxygen generator.

[0015] The lower housing is provided with a mounting boss located inside the housing, the mounting boss having a threaded hole, and the inner wall of the lower housing having a plurality of reinforcing ribs spaced apart.

[0016] The adapter structure is installed inside the housing along the length of the housing, and the air inlet and the air outlet are located on opposite sides of the width of the housing.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. The venting module of this application, by setting a mounting part on the shell, can be directly and stably connected to the mounting surface in different scenarios, greatly improving installation flexibility and scene adaptability. In actual use, users can fix the shell to any target location, such as under the desktop, in a corner of the wall, or next to an office partition, according to the specific spatial layout. Ordinary users can independently complete the installation and fixation, and can quickly adjust the installation position to adapt to changes in the scene. For example, in a conference room scenario, the shell can be fixed to the support structure under the conference table through the mounting part, realizing the concealed installation of the venting module. It will not occupy the desktop space, nor will the exposed module affect the aesthetics of the space, which meets the needs of a compact, beautiful and practical conference room layout. In a home scenario, the shell can be fixed to the living room wall or next to the bedroom cabinet through the mounting part, flexibly matching different home layouts, solving the problem that traditional venting structures are difficult to adapt to multiple installation scenarios.

[0019] Secondly, the adapter structure inside the housing, with one end connected to the air inlet and the other to the air outlet, ensures a stable connection between the oxygen delivery tube and the air outlet. This guarantees smooth oxygen delivery and simplifies the overall structure of the air outlet module. After the oxygen delivered by the oxygen delivery tube enters the adapter structure, it is smoothly guided to the air outlet and output. The entire oxygen delivery path is uniformly planned by the adapter structure, eliminating the need for complex pipe bends or connecting components. This makes the overall module structure more compact, effectively reducing the space occupied during installation. Even in limited spaces like under a desktop or in a narrow wall corner, the air outlet module can be easily accommodated. Furthermore, the adaptable design of the adapter structure and the air inlet allows for stable handling of oxygen delivered by different specifications of oxygen delivery tubes, avoiding compatibility issues caused by direct connection between the oxygen delivery tube and the air outlet. This ensures that the air outlet module maintains a stable oxygen supply even when changing different oxygen generators or oxygen delivery tubes, further enhancing the module's versatility.

[0020] Furthermore, the housing, as the load-bearing foundation of the entire module, integrates the air inlet, outlet, mounting section, and adapter structure into a unified whole. This ensures the positional stability of each component and provides a reliable protective space for oxygen delivery. During use, the housing can effectively block and isolate external dust, moisture, and other impurities, reducing the probability of impurity accumulation affecting oxygen delivery efficiency or causing component damage, thus helping to extend the service life of the outlet module.

[0021] 2. One end of the outlet tube connects to the inlet to stably receive oxygen from the oxygen delivery tube. An adjustable component, movable relative to the outlet tube, allows for flexible changes in oxygen output through movement such as rotation or sliding. In crowded environments like conference rooms, where the number of people and oxygen demand are high, users can increase the outlet volume using the adjustable component to ensure sufficient oxygen supply. Conversely, in single-use spaces like bedrooms, the outlet volume can be reduced to avoid oxygen waste, achieving on-demand oxygen supply. Furthermore, the adjustable outlet angle allows for more precise matching of oxygen output direction to user needs. For users of different heights, body types, and positions, the adjustable outlet angle can be adjusted to improve coverage of the mouth and nose area, enhancing the user experience. This structural design, which combines a support structure with adjustable components to control the flow and direction of oxygen, eliminates the need for additional complex oxygen control parts. Multifunctional adjustment can be achieved simply through the synergy of the two components. This maintains the compactness of the air outlet module and allows ordinary users to quickly adjust oxygen supply parameters without professional operation, meeting the needs of civilian scenarios for flexible adaptation to different numbers of people and different usage locations.

[0022] 3. The first air outlet of the air outlet pipe faces the air outlet, providing a fixed channel for oxygen output. The second air outlet of the adjusting component is aligned with the first air outlet. When the user rotates the adjusting component, the alignment area of ​​the two outlets changes accordingly. The larger the alignment area, the more oxygen passes through the two outlets, and the more oxygen is output from the air outlet. Conversely, the smaller the alignment area, the less oxygen is output, achieving continuous and stable adjustment of the air output and improving user convenience. Simultaneously, the change in the alignment area of ​​the first and second air outlets also adjusts the air outlet coverage angle. When the overlap area between the first and second air outlets is large, the air outlet coverage angle of the air outlet pipe is large; when the overlap area is small, the air outlet coverage angle is small.

[0023] Furthermore, when the two holes are completely misaligned, the adjusting component can directly block the first air outlet, achieving complete oxygen cutoff from the air outlet module. For example, when the meeting room is unoccupied or the oxygen generator is not in operation, there is no need to shut down the oxygen generator itself; simply rotating the adjusting component will cut off the oxygen output, saving energy and preventing unauthorized oxygen leakage. This enhances the intuitiveness of the air outlet module's operation and the user's convenience in adjustment. Users can determine the air outlet status by observing the alignment of the first and second air outlets. Simultaneously, the structure of the hole alignment is highly stable, maintaining precise adjustment even after long-term use and minimizing adjustment failure. Attached Figure Description

[0040] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0041] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0045] like Figures 1 to 4 As shown, an air outlet module for use in an oxygen generator includes a housing 1. The housing 1 has an air inlet 11 connected to an oxygen supply pipe 4 of the oxygen generator, an air outlet 12 for outputting oxygen, and a mounting part 8 that can be connected to a mounting surface. The housing 1 is provided with a transition structure 7. One end of the transition structure 7 is connected to the air inlet 11 to receive oxygen supplied by the oxygen supply pipe 4, and the other end is connected to the air outlet 12 to guide the oxygen to the air outlet 12 for output.

[0046] The venting module of this application, by setting the mounting part 8 on the housing 1, can be directly and stably connected to the mounting surface in different scenarios, greatly improving the installation flexibility and scenario adaptability. In actual use, users can fix the housing 1 to any target location, such as under the desktop, in a corner of the wall, or next to an office partition, according to the specific spatial layout. Ordinary users can complete the installation and fixation independently and can quickly adjust the installation position to adapt to changes in the scenario. For example, in a conference room scenario, the housing 1 can be fixed to the support structure under the conference table through the mounting part 8 to achieve a concealed installation of the venting module. This will not occupy the desktop space, nor will the exposed module affect the aesthetics of the space, which meets the needs of a compact, beautiful and practical conference room layout. In a home scenario, the housing 1 can be fixed to the living room wall or next to the bedroom cabinet through the mounting part 8, flexibly matching different home layouts and solving the problem that traditional venting structures are difficult to adapt to multiple installation scenarios.

[0047] Secondly, the adapter structure 7 inside the housing 1, with one end connected to the air inlet 11 and the other end connected to the air outlet 12, enables a stable connection between the oxygen delivery tube 4 and the air outlet 12. This ensures smooth oxygen delivery and effectively simplifies the overall structure of the air outlet module. After the oxygen delivered by the oxygen delivery tube 4 enters the adapter structure 7, it is smoothly guided to the air outlet 12 and output. The entire oxygen delivery path is uniformly planned by the adapter structure 7, eliminating the need for complex pipe bends or connecting components. This makes the overall structure of the air outlet module more compact, effectively reducing the space occupied during installation. Even in limited spaces such as under a desktop or in a narrow corner, the air outlet module can be easily accommodated. Furthermore, the adaptable design of the adapter structure 7 and the air inlet 11 allows for stable acceptance of oxygen delivered by oxygen delivery tubes 4 of different specifications, avoiding compatibility issues caused by direct connection between the oxygen delivery tube 4 and the air outlet 12. This ensures that the air outlet module maintains a stable oxygen supply even when replacing different oxygen generators or oxygen delivery tubes 4, further enhancing the module's versatility.

[0048] Furthermore, the housing 1, as the supporting foundation of the entire module, integrates the air inlet 11, air outlet 12, mounting part 8, and transition structure 7 into a unified whole. This ensures the positional stability of each component and provides a reliable protective space for oxygen delivery. During use, the housing 1 can effectively block and isolate external dust, moisture, and other impurities, reducing the probability of impurity accumulation affecting oxygen delivery efficiency or causing component damage, thus helping to extend the service life of the air outlet module.

[0049] Figure 2The middle arrow indicates the direction of oxygen flow in the air outlet module. The mounting surface mentioned in this application refers to the target surface on which the air outlet module needs to be installed. When the air outlet module is installed under the desk, the bottom surface of the desk is the mounting surface. When the air outlet module is installed outside the cabinet, the outer side of the cabinet is the mounting surface.

[0050] This application does not limit the connection method between the mounting part 8 and the mounting surface. In one example, the mounting part 8 is provided with a threaded hole, and the threaded hole needs to be aligned with the mounting surface. The mounting part 8 and the mounting surface are detachably connected by a screw that passes through the threaded hole in the mounting surface in sequence. In another example, if the mounting surface is made of a magnetically attractive metal product, the mounting part 8 can be constructed as a magnetic component, and the mounting part 8 is detachably connected to the mounting surface by magnetic attraction.

[0051] As a preferred embodiment of this application, such as Figure 2 , Figure 3 As shown, the adapter structure 7 includes an outlet pipe 2 and an adjusting member; one end of the outlet pipe 2 is connected to the inlet 11 to receive oxygen delivered by the oxygen supply pipe 4, and the adjusting member is movably installed on the outlet pipe 2, and the adjusting member can move relative to the outlet pipe 2 to adjust the amount and angle of oxygen output from the adapter structure 7 to the outlet 12.

[0052] One end of the outlet pipe 2 is connected to the inlet 11 to stably receive oxygen from the oxygen supply pipe 4. An adjustable component, movably installed on the outlet pipe 2, can flexibly change the oxygen output state through movement relative to the outlet pipe 2, such as rotation or sliding. When used in crowded environments such as conference rooms, where there are many people in the relatively enclosed space and the oxygen demand is high, users can increase the output volume using the adjustable component to ensure sufficient oxygen supply. If the scenario changes to a single-person space such as a bedroom, the output volume can be reduced to avoid oxygen waste, achieving on-demand oxygen supply. Simultaneously, the adjustable component's function of adjusting the outlet angle allows for a more precise match of the oxygen output direction to the user's needs. For users of different heights, body types, and positions, the outlet angle can be adjusted using the adjustable component to improve coverage of the user's mouth and nose area, enhancing the user experience. This structural design of the air outlet pipe 2, which combines load-bearing and adjustable components to control the flow and direction of oxygen, eliminates the need for additional complex oxygen control components. Multifunctional adjustment can be achieved simply through the synergy of the two components. This maintains the compactness of the air outlet module and allows ordinary users to quickly adjust oxygen supply parameters without professional operation, meeting the needs of flexible adaptation to different numbers of people and different usage locations in civilian scenarios.

[0053] Specifically, the interior of the air outlet pipe 2 is hollow to form an air outlet channel, which is connected to the air outlet 12 and the oxygen delivery pipe 4. Preferably, a sound-absorbing sponge 10 is provided inside the air outlet channel to reduce noise for the oxygen entering the air outlet pipe 2.

[0054] As a preferred embodiment of this implementation, such as Figure 3 As shown, the air outlet pipe 2 is provided with a first air outlet 21 facing the air outlet 12, and the adjusting member is provided with a second air outlet 31. The adjusting member can rotate relative to the air outlet pipe 2 to adjust the alignment area of ​​the first air outlet 21 and the second air outlet 31. When the first air outlet 21 and the second air outlet 31 are completely misaligned, the adjusting member blocks the first air outlet 21.

[0055] The first air outlet 21 of the air outlet pipe 2 faces the air outlet 12, providing a fixed channel for oxygen output. The second air outlet 31 of the adjusting component is aligned with the first air outlet 21. When the user rotates the adjusting component, the alignment area of ​​the two holes changes accordingly. The larger the alignment area, the more oxygen passes through the two holes, and the more oxygen is output from the air outlet 12. The smaller the alignment area, the less oxygen is output, thus achieving continuous and stable adjustment of the air output and improving user convenience. At the same time, the change in the alignment area of ​​the first air outlet 21 and the second air outlet 31 also adjusts the air coverage angle. When the overlap area of ​​the first air outlet 21 and the second air outlet 31 is large, the air coverage angle of the air outlet pipe 2 is large; when the overlap area of ​​the first air outlet 21 and the second air outlet 31 is small, the air coverage angle of the air outlet pipe 2 is small.

[0056] Furthermore, when the two holes are completely misaligned, the adjusting component can directly block the first air outlet 21, achieving complete oxygen cutoff of the air outlet module. For example, when the conference room is unoccupied or the oxygen generator is not in operation, there is no need to shut down the oxygen generator itself; simply rotating the adjusting component will cut off the oxygen output, saving energy and preventing unauthorized oxygen leakage. This enhances the intuitiveness of the air outlet module's operation and the user's convenience in adjustment. Users can determine the air outlet status by observing the alignment of the first air outlet 21 and the second air outlet 31. Simultaneously, the structure of the hole alignment is highly stable, maintaining precise adjustment even after long-term use and minimizing adjustment failure.

[0057] As a preferred example in this embodiment, such as Figure 3 As shown, the adjusting component is a regulating pipe 3 sleeved on the air outlet pipe 2. The inner wall of the regulating pipe 3 is in contact with the outer wall of the air outlet pipe 2. The regulating pipe 3 rotates around the air outlet pipe 2 to adjust the relative position of the second air outlet 31 and the first air outlet 21.

[0058] The regulating tube 3 is fitted over the outlet tube 2, and its inner wall fits tightly against the outer wall of the outlet tube 2. This effectively reduces the probability of oxygen leakage through the gap between the two, ensuring that the oxygen delivered by the oxygen supply tube 4 is only output through the first outlet hole 21 and the second outlet hole 31, thus reducing oxygen loss. Simultaneously, this fitted structure allows for smoother circumferential rotation of the regulating tube 3, reducing the likelihood of jamming or misalignment. When the user rotates the regulating tube 3, the fitted tube walls provide uniform friction, ensuring a comfortable adjustment process and allowing for more precise alignment of the second outlet hole 31 with the first outlet hole 21, preventing misalignment due to excessive gaps. For example, after installing the module under the desktop, the user can easily and smoothly adjust the regulating tube 3 by reaching in, and the fitted structure prevents dust and impurities from entering the gap, avoiding problems with smooth rotation caused by impurity accumulation after long-term use. In addition, the design of the regulating pipe 3 does not require changing the overall structure of the air outlet pipe 2. The regulating function can be achieved simply by external mounting, which simplifies the module assembly process and reduces production and maintenance costs.

[0059] Preferably, the inner diameter of the regulating pipe 3 is the same as the outer diameter of the air outlet pipe 2, so that the inner wall of the regulating pipe 3 fits against the outer wall of the air outlet pipe 2.

[0060] Specifically, the regulating pipe 3 rotates around the exhaust pipe 2. When the alignment area of ​​the second exhaust port 31 and the first exhaust port 21 changes, the exhaust volume changes with the change in their alignment area, and the coverage of the exhaust angle also changes with the change in their alignment area. In one specific embodiment, when the second exhaust port 31 and the first exhaust port 21 are fully aligned, the oxygen coverage angle ejected from the first exhaust port 21, the second exhaust port 31, and the exhaust port 12 can be 90°. When the second exhaust port 31 and the first exhaust port 21 are partially aligned, the oxygen coverage angle ejected from the first exhaust port 21, the second exhaust port 31, and the exhaust port 12 is 45°.

[0061] As a preferred method in this example, such as Figure 3 As shown, the regulating pipe 3 is provided with a toggle ring edge 32 located around the second air outlet 31, and the toggle ring edge 32 is at least partially located inside the air outlet 12.

[0062] When the air outlet module is installed in a concealed location such as under a desktop or in a wall corner, the adjustment tube 3 may be obscured by the housing 1 or the installation environment, making it difficult for the user to find the adjustment part. However, the actuating ring 32 extending into the air outlet 12 provides the user with a directly accessible adjustment handle. The user does not need to disassemble the housing 1 or reach into a confined space to find the adjustment tube 3; they can easily access the actuating ring 32 through the air outlet 12. A gentle rotation of the ring will cause the adjustment tube 3 to rotate synchronously, achieving alignment adjustment or blocking of the air outlet. For example, when installed under a conference room desktop, attendees do not need to bend over or crawl under the table; they can simply reach into the air outlet 12 and touch the actuating ring 32 to quickly adjust the air volume. Simultaneously, the design of the actuating ring 32 being located around the second air outlet 31 ensures that the rotation of the ring directly and synchronously drives the second air outlet 31, avoiding adjustment delays or misalignment and ensuring the immediacy and accuracy of the adjustment operation. This design, featuring a 32-inch toggle ring and 12 exposed air outlets, greatly enhances operational convenience in concealed installation scenarios without increasing the volume of the air outlet module, making the adjustment process easier and more efficient.

[0063] As another preferred method in this example, such as Figure 3 As shown, the outlet pipe 2 includes a first section 22 and a second section 23 that are interconnected. The first section 22 is connected to the oxygen supply pipe 4 of the oxygen generator. The outer diameter of the first section 22 is larger than the outer diameter of the second section 23. The connection between the first section 22 and the second section 23 has an abutting boss, and the regulating pipe 3 abuts against the abutting boss.

[0064] The outer diameter of the first section 22 of the outlet pipe 2 is larger than that of the second section 23. The abutment formed at the connection between the two can directly abut the end of the regulating pipe 3, restricting the axial movement of the regulating pipe 3 towards the first section 22. At the same time, the first section 22 is directly connected to the oxygen supply pipe 4 of the oxygen generator. Its larger outer diameter can improve the sealing and stability of the connection with the oxygen supply pipe 4, avoiding loosening of the connection or oxygen leakage due to insufficient pipe diameter. For example, during long-term use, when the user repeatedly rotates the regulating pipe 3 to adjust the air output, the regulating pipe 3 will be subjected to a certain axial thrust. However, the abutment can always prevent the regulating pipe 3 from shifting towards the first section 22, ensuring that the second air outlet 31 of the regulating pipe 3 is always at the same axial height as the first air outlet 21 of the outlet pipe 2. It will not cause misalignment of the holes due to displacement, thereby ensuring the accuracy of air output adjustment. In addition, this stepped air outlet pipe 2 structure does not require additional limiting components such as retaining rings or blocks. It only forms abutment bosses through the difference in pipe diameter, which simplifies the structural design, reduces the assembly difficulty, and at the same time improves the overall structural strength of the air outlet pipe 2 and extends its service life.

[0065] Preferably, such as Figure 3As shown, the first section 22 has a connecting end 221 extending toward the air inlet 11, and the connecting end 221 is connected to the oxygen delivery tube 4. An elastic sealing ring gasket 9 is provided between the regulating tube 3 and the first section 22, and the elastic sealing ring gasket 9 is used to seal the connection between the regulating tube 3 and the air outlet tube 2.

[0066] Preferably, such as Figure 3 As shown, the air outlet module also includes a sealing end 5 located on the side of the second section 23 away from the first section 22. The sealing end 5 abuts against the side wall of the regulating pipe 3. The housing 1 also includes a mounting platform 6 located inside the housing 1. The mounting platform 6 is provided with a mounting groove 61. The sealing end 5 is provided with a mounting protrusion 51, which is located in the mounting groove 61.

[0067] The sealing end 5 is located on the side of the second section 23 of the outlet pipe 2 away from the first section 22. Its abutment design with the side wall of the regulating pipe 3 can form an axial limit from the other end of the regulating pipe 3. With the abutment boss, the regulating pipe 3 is restricted between the abutment boss and the sealing end 5, effectively limiting the axial movement of the regulating pipe 3 and ensuring that the alignment accuracy of the second outlet hole 31 and the first outlet hole 21 is not affected after long-term rotational adjustment. At the same time, the sealing end 5 can seal the end of the second section 23 of the outlet pipe 2, preventing oxygen from leaking from the end of the outlet pipe 2, ensuring that all oxygen is guided to the outlet 12 through the first outlet hole 21 and the second outlet hole 31, improving oxygen utilization. In addition, the mounting platform 6 inside the housing 1 cooperates with the mounting protrusion 51 of the sealing end 5 through the mounting groove 61, which can accurately fix the sealing end 5 in a preset position inside the housing 1, thereby indirectly fixing the outlet pipe 2 through the sealing end 5 and preventing the outlet pipe 2 from shaking inside the housing 1. For example, during module transportation or installation, even if subjected to slight impact, the engaging structure of the mounting protrusion 51 and the mounting groove 61 can maintain the stability of the sealing end 5 and the air outlet pipe 2, preventing oxygen supply failure due to component displacement. This double-end limiting and precise positioning design allows the adapter structure 7 to form a stable assembly system within the housing 1, ensuring functional reliability and extending the overall service life of the module.

[0068] Preferably, the sealing end 5 is fixedly installed at the end of the air outlet pipe 2 by adhesive bonding to the regulating pipe 3. When the regulating pipe 3 rotates, the sealing end 5 rotates synchronously. The shape of the mounting protrusion 51 is adapted to the mounting groove 61 and the outer surface is arc-shaped to reduce the frictional resistance when the mounting protrusion 51 rotates.

[0069] As a preferred embodiment of this application, such as Figure 3 As shown, the housing 1 includes an upper housing 13 and a lower housing 14. The upper housing 13 and the lower housing 14 are detachably connected by bolts. The adapter structure 7 is detachably connected to the oxygen supply pipe 4 of the oxygen generator.

[0070] The housing 1 is configured to include an upper housing 13 and a lower housing 14, facilitating the assembly of the air outlet module and allowing for easy removal of the housing 1 for inspection and replacement of its internal components. Furthermore, the detachable connection between the adapter structure 7 and the oxygen delivery tube 4 allows users to flexibly replace the oxygen delivery tube 4 with different lengths or adapter structures 7 compatible with different models and sizes of oxygen delivery tubes 4, improving the adaptability of the air outlet module to oxygen generators. For example, in a large conference room, a longer oxygen delivery tube 4 can be used to place the oxygen generator in a corner, while the air outlet module is fixed under the table, avoiding installation limitations caused by an excessively short oxygen delivery tube 4. This dual detachable design lowers the operational threshold for installation and maintenance, and allows the air outlet module to be adapted to oxygen delivery tubes 4 of different lengths, further expanding its application range in various sizes of civilian spaces.

[0071] As a preferred embodiment of this implementation, such as Figure 3 As shown, the lower housing 14 is provided with a mounting boss 141 located inside the housing 1, the mounting boss 141 is provided with a threaded hole, and the inner wall of the lower housing 14 is provided with a plurality of reinforcing ribs 142 at intervals.

[0072] The mounting boss 141 inside the lower housing 14 is provided with threaded holes, providing preset threaded connection points for fixing components such as the adapter structure 7 and the air outlet pipe 2. Users do not need to drill holes in the inner wall of the housing 1; they only need to connect the components to the threaded holes with bolts to achieve precise positioning, avoiding hole position deviations or damage to the housing 1 caused by drilling, while ensuring the positional stability of the components after assembly. On the other hand, the multiple reinforcing ribs 142 on the inner wall of the lower housing 14 can significantly improve the structural strength of the housing 1. Especially when the lower housing 14 is fixed to the table or wall under the mounting part 8, the reinforcing ribs 142 can resist the stress generated by the weight of the housing 1 itself and minor external collisions, preventing the housing 1 from deforming or cracking.

[0073] As a preferred embodiment of this application, such as Figures 1 to 4 As shown, the adapter structure 7 is installed inside the housing 1 along the length of the housing 1, and the air inlet 11 and the air outlet 12 are located on both sides of the width of the housing 1.

[0074] The adapter structure 7 is installed along the length of the housing 1, which can fully adapt to the long and narrow space of the housing 1, making the layout of the components inside the housing 1 more compact. Especially in narrow installation spaces such as under a desktop, the compact layout can reduce the space occupied by the module. In terms of oxygen delivery efficiency, the air inlet 11 and the air outlet 12 are located on both sides of the width direction of the housing 1, so that the oxygen delivery path forms a straight channel in the width direction. Compared with the design where the air inlet and outlet 12 are on the same side, the delivery distance of oxygen in the housing 1 is significantly shortened, the frictional resistance between oxygen and the inner wall of the housing 1 is reduced, the pressure loss during the oxygen delivery process is reduced, and the air outlet 12 can stably output oxygen at a sufficient pressure.

[0075] Specifically, the air outlet module of this application can also interrupt oxygen production by rotating the regulating pipe 3. When the second air outlet 31 is misaligned with the first air outlet 21, oxygen output stops. After the oxygen concentration in the oxygen delivery pipe 4 of the oxygen generator rises to a certain value, the detector of the oxygen generator detects the oxygen concentration signal and stops oxygen production. Furthermore, this application does not limit the connection method of the oxygen delivery pipe 4, the air inlet 11, and the adapter structure 7 of the oxygen generator. In one specific embodiment, the oxygen delivery pipe 4 extends into the housing 1 through the air inlet 11 and connects to the adapter structure 7, specifically, it connects to the inlet of the air outlet pipe 2 in the adapter structure 7. In another embodiment, the outlet of the oxygen delivery pipe 4 can also be set to be the same size as the air inlet 11 and connect to the air inlet 11, and the adapter structure 7 connects to the air inlet 11, thereby achieving the connection between the oxygen delivery pipe 4 and the adapter structure 7.
