[0047] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0048] Reference Figure 1 , Figure 2 and Figure 8 This application provides a gas storage assembly 200 for a portable oxygen concentrator, the gas storage assembly 200 comprising:

[0049] Gas storage substrate 201 can be a flat plate or a plate-like structure similar to a flat plate. The gas storage substrate 201 is divided into an installation area and a gas passage area. An oxygen inlet pipe 2011 and an oxygen outlet pipe 2012 are formed in the gas passage area.

[0050] A bearing surface is formed on the gas path area, and a first oxygen outlet 20121 and a second oxygen outlet 20122 are provided on the bearing surface. The first oxygen outlet 20121 is connected to the oxygen inlet pipe 2011, and the second oxygen outlet 20122 is connected to the oxygen outlet pipe 2012.

[0051] Gas storage tank 202 is fixedly installed on the installation area and connected to oxygen inlet pipe 2011. Gas storage tank 202 and gas storage base plate 201 together define the accommodating space on the bearing surface.

[0052] Control valve 205 is disposed in the accommodating space and has multiple gas passage interfaces. One gas passage interface of control valve 205 is connected to the first oxygen outlet port 20121, and the other gas passage interface of control valve 205 is connected to the second oxygen outlet port 20122.

[0053] By controlling the control valve 205, the first oxygen outlet 20121 and the second oxygen outlet 20122 are connected, so that the oxygen outlet line 2012 is connected to the oxygen inlet line 2011.

[0054] In the above embodiment, the gas storage base plate 201 is divided into an installation area and a gas passage area, realizing the modular design of the gas storage component 200. The gas storage tank 202 is fixedly installed in the installation area, for example, by welding, bonding, or snapping the gas storage tank 202 to the upper part of the installation area of ​​the gas storage base plate 201, ensuring the overall stability of the gas storage component 200. At the same time, the connection between the gas storage tank 202 and the oxygen inlet pipeline 2011 allows oxygen to smoothly enter the gas storage tank 202 for storage, providing a guarantee for subsequent oxygen supply.

[0055] See Figure 1 and Figure 2 The gas storage substrate 201 provides a dedicated channel for oxygen to enter and exit the gas storage tank 202, clearly defining the flow path of oxygen within the gas storage assembly 200, enabling oxygen to enter and exit the gas storage tank 202 in a predetermined direction. See also Figure 1 The oxygen inlet pipe 2011 and the oxygen outlet pipe 2012 are integrated on the gas storage base plate 201, making the portable oxygen generator more compact, reducing the complexity of the pipes and the space occupied, and helping to optimize the internal space layout of the portable oxygen generator.

[0056] See Figure 2When the gas storage tank 202 is fixedly installed in the mounting area of ​​the gas storage base plate 201, the L-shaped structure formed by the gas storage tank 202 and the gas storage base plate 201 defines the accommodating space. The bearing surfaces on the first oxygen outlet 20121 and the second oxygen outlet 20122 are located in the accommodating space. The bearing surfaces can provide a stable mounting base for the control valve 205, improving the space utilization and structural compactness of the gas storage assembly 200. Moreover, the first oxygen outlet 20121 is connected to the oxygen inlet pipe 2011, used to draw oxygen from the gas storage tank 202 and the oxygen inlet pipe 2011. The second oxygen outlet 20122 is connected to the oxygen outlet pipe 2012. When the second oxygen outlet 20122 is connected to the first oxygen outlet 20121, the oxygen outlet pipe 2012 can deliver oxygen to the oxygen nozzle, making the oxygen intake and exhaust smoother and improving the oxygen supply efficiency.

[0057] See Figure 1 and Figure 3 The oxygen inlet pipe 2011 unidirectionally transmits oxygen from the oxygen supply valve 300 to the storage tank 202, completing the oxygen transfer from the oxygen generating component to the storage component. This ensures that the oxygen flows along the predetermined path, guaranteeing the normal oxygen generation and storage functions of the portable oxygen concentrator. The oxygen outlet pipe 2012 delivers the oxygen stored in the storage tank 202 to the outlet assembly 500 for user use, allowing users to conveniently obtain oxygen generated by the portable oxygen concentrator and realizing its oxygen supply function. Furthermore, through the design and adjustment of the oxygen outlet pipe 2012, a stable pressure of oxygen output from the storage tank 202 can be ensured, meeting the user's needs in different usage scenarios.

[0058] The gas storage assembly 200 provided in this embodiment integrates the gas storage substrate 201 onto the gas storage tank 202. This reduces the need for piping. Simultaneously, the control valve 205 is positioned within the space formed by the gas storage tank 202 and the gas storage substrate 201. While ensuring precise control of oxygen intake and output from the gas storage tank 202, this improves the compactness and space utilization of the gas storage assembly 200, reducing its size and facilitating a portable design for the oxygen generator. Furthermore, the gas storage substrate 201 ensures both precise control of oxygen intake and output from the gas storage tank 202 and maintains a tight seal between the oxygen inlet and outlet.

[0059] In some embodiments, see Figure 2 and Figure 4 The bearing surface is provided with a pressure detection port 2031, and the third air passage interface of the control valve 205 is connected to the pressure detection port 2031;

[0060] A respiratory pressure sensing and detection line 203 is formed in the airway area. One end of the respiratory pressure sensing and detection line 203 is connected to the pressure detection port 2031, and the other end of the respiratory pressure sensing and detection line 203 is an external sensing interface 2032, which is used to connect an external respiratory pressure sensor (not shown in the figure).

[0061] The control valve 205 is configured to switch the regulation to connect the first oxygen outlet 20121 and the second oxygen outlet 20122, or to connect the second oxygen outlet 20122 and the pressure detection port 2031.

[0062] In the above embodiment, the first oxygen outlet 20121 and the second oxygen outlet 20122 can face upward toward the accommodating space. When the control valve 205 is installed in the upper part of the gas path area, it can be opposite to the first oxygen outlet 20121 and the second oxygen outlet 20122, which facilitates the control valve 205 to control the on / off connection between the first oxygen outlet 20121 and the second oxygen outlet 20122.

[0063] In the above embodiments, the control valve 205 can be a two-position three-way valve, such as a solenoid valve or an electric valve. The control valve 205 is used to control the opening and closing of the first oxygen outlet 20121 and the second oxygen outlet 20122, as well as the oxygen flow rate.

[0064] In the above embodiments, the breathing pressure sensor can monitor the oxygen output flow rate inside the portable oxygen concentrator in real time. By monitoring the gas flow, the oxygen supply status of the portable oxygen concentrator can be understood in a timely manner, and it can be determined whether the oxygen supply is on or off and whether the flow rate meets the requirements. Specifically, when the pressure detection port 2031 is connected to the second oxygen outlet port 20122, the breathing pressure sensor detection line 203 can monitor the oxygen flow rate output from the second oxygen outlet port 20122, thereby realizing comprehensive monitoring of the oxygen output of the portable oxygen concentrator, understanding the distribution of oxygen in each output channel, and timely detecting problems such as insufficient or uneven oxygen output.

[0065] See Figure 2The respiratory pressure sensor, used in conjunction with the pressure detection port 2031, allows the sensor to be mounted on the oxygen concentrator's circuit board. The sensor accurately measures the gas flow rate through the port. Simultaneously, the sensor is connected to the oxygen supply control valve 205, enabling precise measurement of the oxygen supply flow rate. The pressure detection port 2031 guides and buffers the gas flow, reducing the impact of turbulence and instability on the sensor, thus improving its reliability and stability. The respiratory pressure sensor detection line 203 connects the sensor and the port 2031, acting as a gas transmission channel. This ensures gas flows smoothly from the port into the sensor, allowing for timely detection of changes in gas flow rate. It also facilitates the arrangement and connection of the detection line, optimizing the overall structure.

[0066] In the initial state, that is, when the oxygen generator is in standby mode and not in use, the control valve 205 can be de-energized, the first oxygen outlet 20121 and the second oxygen outlet 20122 are disconnected, while the second oxygen outlet 20122 is connected to the pressure detection port 2031.

[0067] When a user begins to inhale through the oxygen concentrator's inhalation port, the second oxygen outlet port 20122 and pressure detection port 2031 sense negative pressure. Control valve 205 disconnects the second oxygen outlet port 20122 from the pressure detection port 2031 and connects the first oxygen outlet port 20121 and the second oxygen outlet port 20122, thus ensuring oxygen supply to the user. After a set oxygen supply time (which can be fixed or adjusted according to the user's breathing rate), the first and second oxygen outlet ports 20121 disconnect, and the second oxygen outlet port 20122 connects to the pressure detection port 2031. This process repeats when the user inhales again, and the cycle continues, ensuring continuous oxygen supply to the user.

[0068] In some embodiments, see Figure 2 The first oxygen outlet 20121, the second oxygen outlet 20122 and the pressure detection port 2031 are arranged on the same baseline, and mounting holes 2051 for connecting and fixing control valve 205 are symmetrically provided on the bearing surfaces on both sides of the baseline.

[0069] In the above embodiment, the line connecting the first oxygen outlet 20121, the second oxygen outlet 20122, and the pressure detection port 2031 forms the aforementioned baseline. The collinear arrangement of the first oxygen outlet 20121, the second oxygen outlet 20122, and the pressure detection port 2031 eliminates the problem of pipe crossings in traditional structures and shortens the connection distance between the control valve 205 and each interface. Furthermore, the collinear arrangement of the pressure detection port 2031 and the oxygen outlet improves the accuracy of the detection data.

[0070] See Figure 2 The symmetrically arranged mounting holes 2051 on both sides of the baseline create a mechanical balance for the control valve 205, effectively suppressing vibration or displacement caused by airflow impact or mechanical vibration when the control valve 205 operates. Furthermore, the symmetrical fixing design makes the installation and removal of the control valve 205 more convenient. When installing the control valve 205, it is easier to align the control valve 205 with the mounting holes 2051 and secure it with bolts or other fasteners.

[0071] In some embodiments, see Figure 1 and Figure 2 Both the oxygen inlet pipe 2011 and the oxygen outlet pipe 2012 are arranged parallel to the gas storage base plate 201.

[0072] The first oxygen outlet 20121 and the second oxygen outlet 20122 are arranged radially perpendicular to the gas storage substrate 201.

[0073] In the above embodiment, the oxygen inlet pipe 2011 and the oxygen outlet pipe 2012 are arranged parallel to the gas storage substrate 201. This fully utilizes the planar space of the gas storage substrate 201, resulting in a more compact pipe layout and reducing unnecessary space occupation. The radial direction of the first oxygen outlet 20121 can be the extension direction of the first oxygen outlet 20121, which is the direction of oxygen flow in the first oxygen outlet 20121. Similarly, the radial direction of the second oxygen outlet 20122 can be the extension direction of the second oxygen outlet 20122, which is the direction of oxygen flow in the second oxygen outlet 20122. The first and second oxygen outlets, perpendicular to the gas storage substrate 201, facilitate the control valve's on / off control of the first and second oxygen outlets, improving oxygen flow efficiency. Furthermore, it facilitates a better sealing effect at the connection between the control valve and the oxygen outlet, reducing the risk of oxygen leakage.

[0074] In some embodiments, see Figure 2 The gas storage assembly 200 also includes a pressure relief component 204. An installation groove is provided on the gas passage area. The pressure relief component 204 is disposed in the installation groove and connected to the breathing pressure sensing and detection pipeline 203 through the gas storage base plate 201.

[0075] In the above embodiments, the design of the mounting groove provides a dedicated mounting position for the pressure relief component 204, enabling the pressure relief component 204 to be securely installed in the gas passage area, ensuring the sealing between the pressure relief component 204 and the gas passage area, and preventing oxygen leakage.

[0076] See Figure 2 During the operation of the oxygen concentrator, the pressure in the breathing pressure sensing and detection line 203 may rise abnormally due to a malfunction of the breathing pressure sensor or abnormal airflow fluctuations. After the pressure relief component 204 is connected to the breathing pressure sensing and detection line 203, when the pressure in the breathing pressure sensing and detection line 203 exceeds the set safety threshold, the pressure relief component 204 can open in time to discharge excess gas, thereby reducing the pressure in the breathing pressure sensing and detection line 203, maintaining the pressure balance and stability inside the entire gas storage assembly 200, and preventing safety accidents such as pipe rupture and component damage caused by excessive pressure, thus ensuring the safe operation of the entire gas storage assembly 200 and the oxygen concentrator.

[0077] In some embodiments, see Figure 2 and Figure 4 At least a portion of the mounting groove is located below the control valve 205, and the top surface of the mounting groove is lower than the height of the bearing surface to create a pressure relief space between the mounting groove and the control valve 205.

[0078] In the above embodiment, since at least a portion of the mounting groove is vertically aligned with the control valve 205, when the control valve 205 is adjusting the oxygen flow or performing other operations, if the gas pressure abnormally increases due to improper operation or malfunction, the pressure relief component 204 can respond quickly and release excess pressure in a timely manner, avoiding damage to the control valve 205 and the entire gas system. Furthermore, by reducing the height of the mounting groove, a vertical space difference can be created between the top surface of the mounting groove and the control valve 205. This provides space for the pressure relief airflow and also helps reduce the impact and influence of the pressure relief component 204 on surrounding components when it is opened, protecting other components from damage.

[0079] In some embodiments, see Figure 3 The inlet of the oxygen inlet pipeline 2011 is fitted with a sealing sleeve 2013. The interface of the sealing sleeve 2013 faces the side of the gas storage base plate 201 away from the gas storage tank 202 and is used to connect with the outlet of the oxygen supply valve body 300. This allows oxygen to enter the oxygen inlet pipeline 2011 smoothly and efficiently from the oxygen supply valve body 300, improving the accuracy and stability of oxygen delivery and ensuring the sealing between the inlet of the oxygen inlet pipeline 2011 and the outlet of the oxygen supply valve body 300, thus preventing oxygen leakage from the connection gap.

[0080] In some embodiments, see Figure 5The gas storage base plate 201 is provided with a compressor inlet interface 2016. The inlet of the compressor inlet interface 2016 is used to connect with the outlet of the inlet assembly 900, and the outlet of the compressor inlet interface 2016 is used to supply gas to the compressor assembly 800.

[0081] In the above embodiments, the compressor air inlet interface 2016 can be a section of pipe or a through hole on the gas storage base plate 201. Integrating the compressor air inlet interface 2016 on the edge of the gas storage base plate 201 makes the structure of the gas storage component 200 more compact and integrated, reduces the use of additional connecting parts, facilitates the layout and installation of oxygen generator equipment, and saves space.

[0082] See Figure 5 By connecting the compressor inlet port 2016 to the outlet of the inlet assembly 900, the gas generated from the inlet assembly 900 can smoothly and stably enter the compressor assembly 800, ensuring the continuity and reliability of gas delivery, avoiding gas leakage or poor delivery, and improving the overall performance and working efficiency of the oxygen generator.

[0083] In some embodiments, see Figure 5 and Figure 6 The compressor intake interface 2016 has an internal air inlet 20161. The air inlet 20161 has a stepped surface 20162. The air inlet 20161 is used to insert and cooperate with the outlet end of the intake assembly 900 so that the stepped surface 20162 limits the stepped structure 902 of the outlet end of the intake assembly 900.

[0084] In the above embodiment, a stepped surface 20162 with a certain height difference is formed inside the gas inlet 20161. This can serve as a positioning reference for inserting the outlet end of the air intake assembly 900, ensuring that the outlet end of the air intake assembly 900 can be accurately inserted into the designated position of the gas inlet 20161, guaranteeing the connection accuracy between the two and reducing gas leakage caused by positional deviation. Furthermore, the limiting fit between the stepped surface 20162 and the stepped structure 902 of the outlet end of the air intake assembly 900 ensures the stability and reliability of the connection between the air intake assembly 900 and the gas storage assembly 200.

[0085] Meanwhile, the simple operation of plugging and connecting the air inlet 20161 with the air intake assembly 900 improves the installation efficiency of the air intake assembly 900 and reduces the installation difficulty and cost of the air intake assembly 900.

[0086] In some embodiments, see Figure 7The gas tank 202 is provided with a snap-fit ​​part 2021, which is used to fix and engage with the air intake end of the air intake assembly 900. Through the connection between the snap-fit ​​part 2021 and the air intake end of the air intake assembly 900, a stable fixed position is formed at the air intake end of the air intake assembly 900, ensuring the stability of the connection between the air intake assembly 900 and the gas tank 202.

[0087] In some embodiments, see Figure 7 The snap-fit ​​part 2021 includes a first snap-fit ​​plate 20211 and a second snap-fit ​​plate 20212. The first snap-fit ​​plate 20211 and the second snap-fit ​​plate 20212 are integrally formed on the gas storage tank 202. The first snap-fit ​​plate 20211 and the second snap-fit ​​plate 20212 are used to snap-fit ​​the snap-fit ​​protrusion 901 at the air intake end of the air intake assembly 900.

[0088] In the above embodiments, the one-piece molding process makes the first snap-fit ​​plate 20211, the second snap-fit ​​plate 20212 and the gas storage tank 202 form a continuous whole, which improves the structural strength between the snap-fit ​​part 2021 and the gas storage tank 202 and ensures the reliability of the snap-fit.

[0089] See Figure 7 The snap-fitting plates formed by the first snap-fit ​​plate 20211 and the second snap-fit ​​plate 20212, along with the snap-fitting protrusion 901, allow for quick and convenient connection of the intake assembly 900 to the air tank 202, improving installation efficiency and ensuring the stability of the intake assembly 900. Furthermore, the engagement between the compressor intake port 2016 and the snap-fitting part 2021 positions both ends of the intake assembly 900, ensuring its stability during the intake process.

[0090] See Figure 8 This application provides a portable oxygen generator, which includes the aforementioned gas storage component 200.

[0091] In one embodiment, the portable oxygen concentrator includes a housing, an air intake assembly 900, and the aforementioned air storage assembly 200;

[0092] An air intake hood is provided on the housing, the air intake end of the air intake assembly 900 faces the air intake hood, and the air outlet end of the air intake assembly 900 is connected to the air storage base plate 201 of the air storage assembly 200.

[0093] In the above embodiment, the oxygen generator's air intake area is equipped with an air intake hood, which can have multiple air intake holes to allow air to flow more smoothly to the air intake assembly 900, improving air intake efficiency. Simultaneously, the shape and size of the air intake hood can be designed according to the air intake requirements of the air intake assembly 900, ensuring that air is evenly distributed at the air intake end of the air intake assembly 900. Furthermore, the air intake end of the air intake assembly 900 faces the air intake hood, which shortens the path of air entering the air intake assembly 900, reduces air resistance during the air intake process, and improves air intake efficiency.

[0094] See Figure 8 After the air intake assembly 900 filters the air, it delivers the treated air to the air storage base plate 201 of the air storage assembly 200 through the air outlet, so that the airflow can be input to the compressor assembly 800 through the compressor intake interface of the air storage base plate 201, thus ensuring the efficiency of air compression.

[0095] In some embodiments, see Figure 8 The portable oxygen concentrator also includes an air intake assembly 900 and a fan 810. The air intake assembly 900 is located above the control valve 205, and the fan 810 is located above the air intake assembly 900.

[0096] In the above embodiment, the control valve 205, the air intake assembly 900, and the fan 810 are arranged sequentially from bottom to top, forming a sandwich-like stacked structure. This vertical layered design reduces space occupancy and is suitable for the compact structure requirements of portable oxygen concentrators. Furthermore, the fan 810 not only assists in heat dissipation but also enhances the air intake of the compressor, achieving a balance between efficient oxygen production and low energy consumption.

[0097] In some embodiments, see Figure 7 and Figure 8 The intake assembly 900 and the fan 810 occupy the aforementioned accommodating space, so that the air storage assembly 200, together with the intake assembly 900 and the fan 810, occupy a cuboid-like space.

[0098] In the above embodiments, the combination of the gas storage component 200, the air intake component 900 and the fan 810 forms a structure with an approximately rectangular cross-section, realizing a regular layout of the gas storage component 200, the air intake component 900 and the fan 810, providing a space basis for the miniaturization design of the portable oxygen concentrator, reducing the overall size of the device and improving the integration of the internal components of the portable oxygen concentrator.

[0099] In some embodiments, see Figure 8The portable oxygen concentrator also includes a compressor assembly 800 and a molecular sieve cylinder 400, which are spaced apart on the upper and lower parts of the housing. A fan 810 is located inside the housing on the side near the air intake hood and faces the compressor assembly 800.

[0100] In the above embodiments, the compressor assembly 800 and the molecular sieve cylinder 400 are arranged vertically and alternately within the housing, which makes full use of the vertical space of the housing, allowing the oxygen generator to accommodate more components within a limited volume, improving space utilization, and facilitating the miniaturization and portability of the oxygen generator. Furthermore, the vertical spacing between the compressor assembly 800 and the molecular sieve cylinder 400 reduces mutual interference between them, ensuring the normal operation of the molecular sieve cylinder 400.

[0101] See Figure 8 The fan 810 is positioned close to the air intake shroud, which enhances heat dissipation by utilizing the airflow around the shroud. Simultaneously, its orientation towards the compressor assembly 800 allows the fan 810 to more directly dissipate the heat generated by the compressor assembly 800. Furthermore, the fan 810's adjacent placement to the air intake assembly 900 facilitates the guidance of airflow through the fan 810. Outside air is then delivered through the air intake assembly 900 to the interior of the compressor assembly 800 for compression, ensuring adequate gas compression.

[0102] In some embodiments, see Figure 8 The portable oxygen concentrator includes an inner cavity support 600, which is spaced apart from the mounting support 100. The inner cavity support 600 is provided with a third through-channel 601. The molecular sieve cylinder 400 can be installed and cooperated with the mounting support 100 and the third through-channel 601 to limit the two ends of the molecular sieve cylinder 400. The molecular sieve cylinder 400 and the inner cavity support 600 can be fixed with screws to ensure the stability of the molecular sieve cylinder 400.

[0103] See Figure 8 The gas, pressurized by the compressor assembly 800, is output from the outlet of the compressor assembly 800 and then distributed by the gas distribution valve to the interior of the molecular sieve cylinder 400. After entering the molecular sieve cylinder 400, the gas undergoes pressure swing adsorption, and oxygen is delivered from the outlet of the molecular sieve cylinder 400 to the gas storage tank 202 via the oxygen supply valve body 300, ensuring the oxygen storage capacity of the portable oxygen generator.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
