Description

Technical Field

[0001] This application relates to the field of medical and health equipment technology, specifically to a portable oxygen supply device, and more particularly to a wearable oxygen generator that deeply integrates a modular pressure swing adsorption oxygen generation system with wearable clothing. Background Technology

[0002] With the aging population and rising incidence of chronic respiratory diseases, long-term home oxygen therapy has become an important treatment for maintaining patients' vital signs and improving their quality of life. For those who need continuous or intermittent oxygen inhalation, portable oxygen concentrators offer the possibility of leaving their homes and participating in social activities, making them key equipment for achieving "oxygen-rich living." Currently, most portable oxygen concentrators on the market use pressure swing adsorption (PSA) technology. Its core principle is to use a compressor to pressurize air, forcing it through an adsorption bed filled with special molecular sieves. Based on the difference in the molecular sieves' adsorption capacity for nitrogen and oxygen, nitrogen and oxygen are separated, thereby producing high-concentration medical oxygen.

[0003] However, although existing technologies have achieved portability of oxygen concentrators to some extent, a series of deep-seated technical bottlenecks still exist in practical applications, especially in the pursuit of "unobtrusive wearability" and coping with complex environments. These bottlenecks are specifically reflected in the following aspects: First, the lack of ergonomic design results in poor carrying burden and comfort. Most existing portable devices are backpack-style or crossbody-style, typically weighing 2-5 kg, requiring single-point weight support from the shoulder or torso. For elderly or frail patients, carrying these devices for extended periods causes significant physical strain and fatigue, limiting their mobility and range of motion. Furthermore, as external attachments, these devices are prone to swaying and bumping during walking, sitting, or lying down, resulting in poor comfort and falling far short of the "wearable" standard that integrates seamlessly with the human body.

[0004] Second, the integration level is low, and the system layout is scattered. Some so-called "wearable" solutions are essentially still just laying out and fixing the various separate components of the oxygen concentrator (such as the compressor, molecular sieve, and gas storage tank) in different positions on clothing, for example, with the oxygen generation system in the back and the oxygen storage system in the front. This "planar and scattered" layout not only leads to lengthy and complex internal gas and electrical connections, increasing potential failure risks and energy losses, but also fails to achieve true structural integration and compactness, falling far short of the modular and easy-to-maintain design concept.

[0005] Third, heat dissipation becomes a fundamental constraint on integration. The compressor, the core heat source of the oxygen concentrator, generates a large amount of heat when operating in a compact, enclosed wearable environment. The pursuit of high integration and miniaturization inevitably leads to a drastic reduction in heat dissipation space, making the problem of heat accumulation increasingly prominent. Existing technologies generally lack active, directional heat dissipation designs for wearable environments, resulting in excessively high local temperatures in the device. This not only seriously affects the performance of the compressor and the lifespan of the entire device, but may also cause burning discomfort due to direct heat transfer to the human body, severely impacting the user experience and constituting a core technological obstacle to achieving highly integrated wearable devices.

[0006] Fourth, in special application scenarios such as high-altitude outdoor activities, the aforementioned shortcomings are further amplified. High-altitude participants not only need to cope with low pressure and hypoxia, but also face environmental challenges such as low temperatures, strong winds, and complex terrain. Traditional backpack-style oxygen concentrators, with their bulky structure, severely affect the flexibility and safety of movement; battery performance deteriorates sharply in low-temperature environments, resulting in questionable battery life; and fixed oxygen supply modes cannot match the drastically changing oxygen demands during activities, leading to significant energy waste. Therefore, existing technologies fall far short of meeting the urgent needs of high-altitude outdoor activities for lightweight, integrated, weather-resistant, efficient, and intelligent portable oxygen supply devices.

[0007] In summary, there is an urgent need in this field for a novel technical solution that provides a truly compact, well-ventilated, safe, comfortable, and adaptable wearable oxygen generation system that can adapt to complex environments. Summary of the Invention

[0008] To address the technical problems existing in the prior art, this application provides a wearable oxygen generation system. Through an innovative front and rear modular layout, a hidden wiring system, and an intelligent control scheme, it achieves deep integration of the oxygen generation device with wearable clothing, thereby improving the portability, comfort, and safety of the device, and providing a brand-new technical solution for mobile oxygen generation applications.

[0009] To achieve the above objectives, this application provides the following technical solution: On one hand, this application provides a wearable oxygen generation system, including: A garment having multiple internal pockets and a back area and a front area; An oxygen-generating core module is detachably housed in an internal pocket in the back area of ​​the garment, the oxygen-generating core module including at least one compressor; At least one molecular sieve adsorption unit is detachably housed in an internal pocket in the front area of ​​the garment; A wiring channel pre-embedded in the interlayer structure of the wearable clothing, the wiring channel extending from the back area to the front area; and a connecting pipeline, the connecting pipeline being housed in the wiring channel and connecting the oxygen generation core module and the molecular sieve adsorption unit.

[0010] By placing the oxygen-generating core module in the back area and the molecular sieve adsorption unit in the front area, a front-to-back weight balance and multi-point distributed load are achieved, avoiding the single-point concentrated load problem of traditional backpack-style devices and reducing pressure on the shoulders, neck, and spine. At the same time, the airway tubing and electrical signal cables are concealed inside clothing through channels, eliminating safety hazards and aesthetic issues caused by exposed tubing, allowing the device to truly integrate into everyday clothing.

[0011] In some embodiments, the oxygen generation core module further includes a gas path integration unit and a gas storage box.

[0012] In some embodiments, within the oxygen generation core module, the compressor, the gas path integration unit, and the gas storage box are stacked vertically.

[0013] By using a vertically stacked, three-dimensional spatial layout, the thickness of the equipment is greatly reduced in the direction perpendicular to the back, thus reducing the area it occupies, making the equipment more compact, and minimizing interference with human activities.

[0014] In some embodiments, the oxygen generation core module further includes a cooling fan, which is disposed on the side of the gas storage box away from the gas path integration unit, and the air outlet direction of the cooling fan passes through the gas storage box and the gas path integration unit and points towards the compressor, so as to form a directional cooling airflow.

[0015] Through directional heat dissipation design, the airflow of the cooling fan can be directed to heat-generating components such as the compressor, achieving efficient active heat dissipation, effectively controlling the operating temperature of core components, extending the service life of the equipment, and reducing the transfer of heat to the human body in conjunction with heat insulation measures.

[0016] In some embodiments, the gas path integration unit includes an integrated gas path board, which has a built-in gas path connecting the compressor, the gas storage box, and the molecular sieve adsorption unit connected through the wiring channel.

[0017] By using an injection-molded integrated gas circuit board, the complex gas circuit system that requires multiple independent pipes and multiple connectors in the traditional solution is integrated into a single plate structure with gas channels inside. This significantly reduces the number of connection points, lowers the potential risk of leakage and failure rate, and improves the reliability and airtightness of the system.

[0018] In some embodiments, the molecular sieve adsorption unit includes at least two molecular sieve barrels, and the built-in gas channel of the integrated gas circuit board includes a channel for alternately supplying compressed air to the two molecular sieve barrels.

[0019] By alternately supplying compressed air to the two molecular sieve chambers, the alternating adsorption-desorption cycle of the molecular sieve is achieved, ensuring a continuous output of oxygen.

[0020] In some embodiments, the molecular sieve adsorption unit includes two molecular sieve barrels symmetrically arranged on the left and right sides of the front of the clothing to form a front-to-back weight balance with the oxygen-generating core module arranged in the back area.

[0021] By symmetrically placing molecular sieve barrels on the left and right sides of the chest, a front-to-back weight balance is achieved with the oxygen-generating core module on the back, ensuring that the body's center of gravity does not shift significantly due to the loading of the device, thus significantly improving the comfort of wearing it for extended periods.

[0022] In some embodiments, the wiring channel is provided with: a compressed air supply pipeline and an oxygen-enriched gas return pipeline arranged along the waist area of ​​the clothing; and a product oxygen output pipeline.

[0023] By routing the tubing along the waist area, the core oxygen-generating module on the back is connected to the molecular sieve adsorption unit on the front, allowing for reasonable control of the tubing length. This avoids the excessive length and pressure loss that would result from the tubing passing through the shoulders or other areas, while ensuring both comfort and flexibility of movement.

[0024] In some embodiments, the system further includes an interaction and output unit disposed in the upper front area of ​​the wearable garment, the unit including a power switch and an oxygen output interface; the product oxygen output pipeline is used to deliver finished oxygen from the oxygen generation core module to the oxygen output interface.

[0025] By integrating the power switch and oxygen output interface into the upper front area, users can easily operate the device, observe its status, and connect the nasal oxygen cannula without removing their clothing while wearing it. This fully considers users' usage habits and convenience needs, achieving the goal of "ready to use as soon as you put it on".

[0026] In some embodiments, a heat-insulating material layer is provided between the oxygen-generating core module and the inner layer of the wearable clothing. By providing the heat-insulating material layer, a heat insulation barrier is formed between the oxygen-generating core module and the human body, blocking the path of heat transfer to the human body. Even if the temperature of the core component reaches a high temperature, the user's perceived temperature can be controlled within a comfortable range, ensuring wearing comfort.

[0027] Compared with the prior art, this application has one or more of the following beneficial effects and technological advancements: Compared with existing technologies, the wearable oxygen generation system of this application has the following advantages: First, the modular layout with separate front and back sections achieves a balanced weight distribution. The core oxygen-generating module is located on the back, while molecular sieve barrels are symmetrically placed on the left and right sides of the chest. This avoids the problem of concentrated weight on a single point, which is common in traditional backpack-style devices. This significantly reduces the peak stress on the shoulders, neck, and spine, improving comfort during extended wear.

[0028] Secondly, by concealing all air pipes and electrical signal cables inside clothing through the wiring channels, the safety hazards such as tangling and snagging caused by exposed pipes are eliminated, allowing the equipment to truly integrate into everyday clothing and reducing the psychological burden on users.

[0029] Third, by using a vertical stacking design for the internal components of the core oxygen generation module, the thickness of the device is greatly reduced in the direction perpendicular to the back, thus reducing the occupied area and minimizing interference with human activities. At the same time, it shortens the gas path connection distance, reducing the number of connection points and potential leakage risks.

[0030] Fourth, by using an injection-molded integrated gas circuit board, the complex gas circuit system that requires multiple independent pipes and multiple connectors in the traditional solution is integrated into a single plate structure with gas channels inside, which greatly reduces the number of gas connection points and improves the reliability and airtightness of the system.

[0031] Fifth, the active cooling airflow generated by the directional cooling fan precisely cools the core heat source compressor. Combined with the air duct structure and ventilation network, it expels hot air, effectively controlling the compressor's steady-state operating temperature and extending the equipment's lifespan. Simultaneously, the dual insulation effect of the insulation material layer and insulation pad blocks the path of heat transfer to the human body, ensuring wearing comfort.

[0032] Sixth, by integrating the power switch and oxygen output interface into the upper front area, users can conveniently operate the device, observe its status, and connect the nasal oxygen cannula without removing their clothing while wearing the device, achieving the goal of "ready to use as soon as you put it on" and significantly improving ease of use.

[0033] Seventh, through modular design, each functional module can be independently removed from the clothing pocket for maintenance, replacement and upgrade, reducing maintenance difficulty and usage costs.

[0034] In summary, the wearable oxygen generation system of this application has the characteristics of compact structure, good heat dissipation, comfortable wear and concealed appearance. It is particularly suitable for scenarios that require long-term movement and continuous oxygen inhalation in complex environments, such as high-altitude hiking, mountain work and outdoor exploration.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings showing multiple embodiments according to this application.

[0045] In this embodiment, to facilitate the description of the spatial relationships between the components of the wearable oxygen generation system, the following orientation conventions are made: (1) Front area / front part: refers to the area of ​​the human body covered by clothing, including the left and right sides and the central part of the chest; (2) Back area / back: refers to the area of ​​the human back covered by clothing, including the upper, middle and lower parts of the back; (3) Above / Upper part: refers to the vertical upward direction relative to the human body's standing posture; (4) Below / Lower part / Bottom: refers to the direction that is vertically downward relative to the human body when standing; (5) Left / Right side: Based on the left and right sides when the wearer is facing forward; (6) Vertical direction: refers to the direction parallel to the extension of the spine when the human body is standing; (7) Horizontal direction: refers to the plane direction that is perpendicular to the above vertical direction.

[0046] This application provides a wearable oxygen generation system designed to solve the technical problems of traditional portable oxygen concentrators, such as inconvenience in carrying, discomfort in wearing, exposed tubing, and poor heat dissipation. By highly integrating a molecular sieve pressure swing adsorption oxygen generation system into everyday clothing, an intelligent and user-friendly oxygen inhalation experience is achieved.

[0047] like Figure 1 and Figure 2As shown, this application provides a wearable oxygen generation system. The core design concept of this wearable oxygen generation system lies in achieving a balance between weight and functional integration through a modular layout with separate front and rear sections. The wearable oxygen generation system includes a garment 611, an oxygen generation core module 10, a molecular sieve adsorption unit 11, and a wiring channel 613. In this embodiment, the garment 611 is a vest, employing a three-layer composite fabric structure: an outer layer of abrasion-resistant and water-repellent fabric, a middle layer of high-elasticity and breathable mesh fabric, and an inner layer of skin-friendly and moisture-wicking functional textile. The garment 611 has multiple internal pockets 612. The position and size of these pockets are specifically designed according to the shape and weight of each functional module. In some optional embodiments, the back area of ​​the garment 611 has a first pocket along the central axis for accommodating the oxygen generation core module 10; the left and right sides of the front area have symmetrically arranged second and third pockets for accommodating the molecular sieve adsorption unit 11; and the waist side has a fourth pocket for accommodating the power supply module 40. Each pocket has Velcro or quick-release buckles on its edge, which not only keeps the components in place during movement, but also makes it easy for users to quickly remove the components for charging or maintenance.

[0048] The middle layer of the wearable garment 611 contains a pre-embedded wiring channel 613. This wiring channel 613 is made of flexible fabric tubing or a plastic sheath and is laid along the sewing lines of the garment. It is used to accommodate and guide the air connection pipe 123, as well as power cables and signal cables. In this embodiment, the wiring channel 613 extends from the back to the front along the waist area of ​​the wearable garment 611. It mainly houses compressed air supply pipes, oxygen-enriched gas return pipes, and product oxygen output pipes. These pipes are not visible from the outside, eliminating the risk of tangling and snagging caused by exposed pipes in traditional portable devices.

[0049] like Figure 2 and Figure 3As shown, the oxygen-generating core module 10 is located on the central axis of the back area of ​​the clothing 611. The internal components of the oxygen-generating core module 10 adopt a vertically stacked three-dimensional spatial layout, which greatly reduces the thickness of the device in the direction perpendicular to the back. The internal components, from bottom to top, are an air intake purification unit 22, a compression power unit 21, an air path integration unit 12, and an oxygen storage unit 13. The air intake purification unit 22 includes a base 221, an air filter 222, and a dustproof and breathable membrane 223. The base 221 is a rectangular plastic base plate with a plurality of evenly distributed base air intake holes 2211 on the bottom surface. The hole diameter is 10 to 20 mm, and the number is 2 to 4. Above the air inlet 2211 of the base, an air filter 222 and a dustproof and breathable membrane 223 are stacked in sequence. The air filter 222 can be implemented as a multi-layer gradient density non-woven fabric, capable of intercepting particles larger than 5 micrometers. The dustproof and breathable membrane 223 can be implemented as a polytetrafluoroethylene microporous membrane with a pore size of 0.2 to 0.5 micrometers, allowing air to pass through while blocking dust and moisture. The air filter 222 and the dustproof and breathable membrane 223 are fixed in the base 221 by a slot or adhesive, and can be removed for cleaning or replacement by the user periodically. The filtered clean air enters the inner cavity of the base 221 through the air inlet 2211 and flows upward to the air inlet of the compressor 211. In the gas path connection between the oxygen generation core module 10 and the molecular sieve adsorption unit 11, the wiring channel 613 plays a key bridging role. Specifically, the compressed air supply line starts from the quick-connect air head 1211 on the bottom of the gas path integration unit 12, passes through the pre-reserved opening in the side wall of the first back pocket, enters the wiring channel 613, extends horizontally along the waist area, and then splits into two paths in the front area. These paths lead out from the pre-reserved openings in the inner walls of the second and third pockets, respectively, and connect to the air inlets of the first molecular sieve barrel 1111 and the second molecular sieve barrel 1112 via quick connectors. The oxygen-enriched gas return line follows the opposite direction, starting from the air outlets of the two molecular sieve barrels 111, converging through the wiring channel 613, and returning to the oxygen collection interface of the gas path integration unit 12. The product oxygen output line starts from the side air outlet of the gas storage box 131, extends upward along the wiring channel 613 to the oxygen output interface 621 in the upper front area. With this wiring scheme, the total length of the gas path is shortened compared to traditional external piping schemes, and the number of pipe connection points is reduced from more than 12 to 6, significantly improving the airtightness and reliability of the system.

[0050] The compression power unit 21 includes a compressor 211 and a shock-absorbing pad 212. In some optional embodiments, the compressor 211 is a miniature oil-free piston or scroll compressor with dimensions of approximately 60×50×40 mm and a weight of approximately 200 to 300 grams. The air intake purification unit 22 is located on the side of the compressor 211 opposite to the air circuit integration unit 12. Furthermore, the bottom of the compressor 211 has four screw holes, through which the shock-absorbing pad 212 is mounted on the top surface of the air intake purification unit 22. The shock-absorbing pad 212 can absorb the high-frequency mechanical vibration generated by the compressor 211 during operation, thereby reducing the amplitude of vibration transmitted to the clothing and significantly improving wearing comfort. To ensure the long-term reliable operation of the tubing within the wiring channel 613, the clothing 611 is provided with flexible support structures at key locations along the wiring channel 613.

[0051] like Figure 3 As shown, at least one gas path integration unit 12 is located directly above the compressor 211. In an optional embodiment, the gas path integration unit 12 is located on one side of the compressor 211, and the gas storage box 131 is located on the side of the gas path integration unit 12 opposite to the compressor 211. Structurally, the gas path integration unit 12 can be divided into an upper gas path assembly 121 and a lower gas path assembly 122 that are fixed to each other, which together constitute a highly integrated gas path control core. In some optional embodiments, the upper gas path assembly 121 is an integrated gas path plate body, which is made of reinforced nylon or ABS engineering plastic through precision injection molding. Its core function is to provide a stable base plate containing a preset gas channel 1212, and to integrate all external gas path connection points, such as quick-connect gas heads 1211 for connecting the compressor 211, molecular sieve barrel 111 and gas storage box 131, on its surface. This design internalizes the originally complex pipeline network into a single component, ensuring the integrity, sealing and low flow resistance of the gas path. The lower gas path assembly 122, serving as a dynamic control module, is fixedly connected to the bottom surface of the upper gas path assembly 121. The lower gas path assembly 122 integrates a valve body for controlling gas path switching, responsible for precise timing control of the alternating adsorption-desorption cycle between molecular sieve barrels, as well as the emission of nitrogen during the desorption phase. In some optional embodiments, the upper gas path assembly 121 and the lower gas path assembly 122 are fastened together, with a sealing ring between them to ensure airtightness. This separate design, combining the upper main board with the lower valve assembly, not only significantly reduces the number of gas path connection points, improving system reliability, but also enhances the maintainability of the control components.

[0052] The oxygen storage unit 13 includes a gas storage box 131, located directly above the integrated gas circuit board. The gas storage box 131 is a sealed rectangular cavity, approximately 100 to 150 mm long, 60 to 80 mm wide, and 30 to 50 mm high, with a volume of approximately 200 to 500 ml. The bottom surface of the gas storage box 131 has an air inlet, which connects directly to the oxygen outlet on the top surface of the integrated gas circuit board via a quick-connect fitting 1211. Preferably, the distance between the air inlet and outlet is no more than 5 mm, forming a zero-pipe connection, thereby significantly shortening the gas path length and reducing gas path resistance. The side of the gas storage box 131 has an air outlet, connected to an oxygen output pipeline laid through a wiring channel 613. This oxygen output pipeline delivers finished oxygen to an oxygen supply output unit located in the upper front area of ​​the clothing.

[0053] Through the aforementioned vertical stacking structure, the three core components of the oxygen-generating core module 10 are stacked sequentially in the vertical direction. The vertical height of the oxygen-generating core module 10 is approximately 150 to 220 millimeters, occupying a two-dimensional plane area of ​​approximately 100 × 80 millimeters, forming a compact cubic structure. This layout minimizes the airway connection distance between components, significantly shortening the total airway length of the entire wearable oxygen-generating system compared to a distributed layout. This reduces the amount of tubing used, the number of connection points, and improves the system's airtightness and reliability, while also reducing interference with human activity.

[0054] like Figure 3 As shown, in a preferred embodiment, the oxygen generation core module 10 further includes an active heat dissipation unit 51, which includes a cooling fan 511. The cooling fan 511 is positioned above the oxygen generation core module 10. Specifically, it is fixed to the top or side of the gas storage box 131 using screws or clips through the mounting holes at the four corners of the cooling fan 511. The cooling fan 511 is a miniature axial or centrifugal fan. After being fixed, the cooling fan 511 directs its airflow towards the compressor 211. Specifically, the cooling fan 511 is positioned on the side of the gas storage box 131 away from the air path integration unit 12, forming a directional cooling airflow. Specifically, after the cooling airflow is blown out from the cooling fan 511, it flows downwards vertically, passing sequentially through the outer shell of the gas storage box 131 and the surface of the air path integration unit 12, finally reaching the outer shell surface of the compressor 211 located at the bottom. As the compressor 211 is the main heat source of the system, its outer casing surface temperature can reach 50 to 70 degrees Celsius during operation. When a high-speed airflow passes over its surface, the heat can be quickly carried away through forced convection heat exchange, thereby effectively controlling the operating temperature of the core components and extending the service life of the equipment.

[0055] like Figure 2As shown, the inner layer of the wearable garment 611 is equipped with an air duct structure 512, which includes several flexible air guide vanes arranged along the airflow direction to guide and converge the airflow, preventing the airflow from dispersing to unrelated areas. Along the hot air exhaust path, the upper back area of ​​the wearable garment 611 uses breathable mesh fabric or has ventilation holes to form a breathable network, allowing the heat-carrying airflow to be smoothly exhausted to the external environment after passing through the oxygen-generating core module 10 and the compressor 211, preventing heat accumulation inside the garment.

[0056] The start and stop of the cooling fan 511 are automatically controlled by the circuit control board 311 based on the feedback signal from the temperature sensor 322. In some optional embodiments, the temperature sensor 322 is an NTC thermistor or a digital temperature chip, attached to the compressor 211 housing near the cylinder via thermal grease, and its leads are connected to the circuit control board 311 via wiring channel 613. When the temperature sensor 322 detects that the compressor 211 housing temperature exceeds the upper threshold temperature, for example, 55 degrees Celsius, the microprocessor 312 sends a start signal to the drive circuit of the cooling fan 511, and the cooling fan 511 starts running; when the temperature drops to the lower threshold temperature, for example, below 45 degrees Celsius, a stop signal is sent, and the cooling fan 511 stops. This temperature-controlled start-stop strategy ensures timely heat dissipation while avoiding unnecessary energy consumption and noise, allowing the steady-state operating temperature of the compressor to be controlled between 50 and 55 degrees Celsius, a significant reduction compared to the temperature without an active cooling solution.

[0057] In some optional embodiments, a heat insulation unit 52 is provided between the oxygen-generating core module 10 and the inner layer of the wearable clothing 611. This heat insulation unit includes a heat insulation material layer 522. The heat insulation material layer 522 is a piece of heat-insulating fabric or composite heat-insulating film, slightly larger than the projected area of ​​the oxygen-generating core module 10, and about 3 to 5 millimeters thick. In some optional embodiments, the heat insulation unit 52 uses a functional fabric containing aerogel particles or a multi-layer aluminum foil composite heat-insulating film. The heat insulation material layer 522 is fixed to the position between the inner layer of the wearable clothing 611 and the oxygen-generating core module 10 by sewing or bonding. In some optional embodiments, a heat insulation pad 521 is also attached to the outer shell of the compressor 211. The heat insulation pad 521 is a pad that matches the size of the contact surface of the compressor 211 outer shell and is made of a material with low thermal conductivity, such as silicone sponge or aerogel pad. The heat insulation pad 521 is attached to the side of the compressor 211 outer shell facing the human body, i.e., the back side, by adhesive or clips. Through the dual insulation effect of the heat insulation pad 521 and the heat insulation material layer 522, a heat insulation barrier is formed between the compressor and the human body, blocking the path of heat transfer to the human body. Even if the temperature of the core components reaches a high temperature, the user's perceived temperature can be controlled within a comfortable range, ensuring wearing comfort.

[0058] like Figure 1As shown, the molecular sieve adsorption unit 11 is located in the front area of ​​the garment 611, and includes two molecular sieve barrels 111. In a specific implementation, it includes a first molecular sieve barrel 1111 and a second molecular sieve barrel 1112. The two molecular sieve barrels 111 are symmetrically arranged on the left and right sides of the front of the garment, respectively housed in the aforementioned second and third pockets, to achieve front-to-back weight balance with the oxygen-generating core module 10 located in the back area. Each molecular sieve barrel 111 is a sealed cylindrical container with an outer shell made of aluminum alloy, approximately 80 to 120 mm in height and approximately 40 to 60 mm in diameter, filled with molecular sieve material 112. The molecular sieve material 112 can be a lithium-type zeolite molecular sieve, which has selective adsorption capacity for nitrogen and can adsorb nitrogen from the air under pressure, thus separating oxygen. In the gas path connection between the molecular sieve adsorption unit 11 and the oxygen-generating core module 10, the pipeline arrangement in the wiring channel 613 follows the principles of shortest path and symmetrical balance. The compressed air supply pipeline originates from the gas path integration unit 12 at the back and extends horizontally within the wiring channel 613. Near the front area, it adopts a Y-shaped branch structure, with the lengths of the two branch pipelines strictly controlled within an error range of no more than 10 mm to ensure consistent inlet pressure and flow rate for the two molecular sieve barrels 111. The oxygen-enriched gas return pipeline also adopts a symmetrical layout, with the two pipelines converging into a single main pipeline within the wiring channel 613 before returning to the back.

[0059] The first molecular sieve barrel 1111 and the second molecular sieve barrel 1112 are respectively provided with interfaces at the top and bottom. These interfaces are connected to the gas path integration unit 12 located on the back through compressed air supply pipelines and oxygen-enriched gas return pipelines arranged in the wiring channel 613. Specifically, the compressed air supply pipeline starts from the integrated gas path plate of the gas path integration unit 12 on the back, extends along the wiring channel 613 in the waist area to the left and right sides of the front chest, and connects to the air inlets of the two molecular sieve barrels 111; the oxygen-enriched gas return pipeline starts from the air outlets of the two molecular sieve barrels 111, and also returns along the waist area to the oxygen collection interface of the integrated gas path plate of the gas path integration unit 12 on the back. Furthermore, by controlling the solenoid valve in the gas channel built into the integrated gas path plate, compressed air can be alternately supplied to the two molecular sieve barrels 111, so that they alternately perform adsorption and desorption cycles, thereby ensuring a continuous oxygen output. This symmetrical layout of molecular sieve barrels on both sides of the chest, together with the oxygen-generating core module 10 on the back, creates a front-to-back weight balance, preventing the body's center of gravity from shifting significantly due to device loading, thus significantly improving comfort during long-term wear.

[0060] like Figure 1 and Figure 3As shown, the wearable oxygen generation system also includes a control and circuit module 30, which comprises a main control processing unit 31, a sensing and detection unit 32, and a human-machine interaction unit 33. The main control processing unit 31 includes a circuit control board 311, which is a rectangular printed circuit board integrating a microprocessor 312 and a power management chip 313. The microprocessor 312 is pre-installed with an oxygen generation control program, capable of controlling the start and stop of the compressor 211, the opening and closing sequence of the solenoid valves in the lower air path assembly 122, and the start and stop of the cooling fan 511 according to a preset working mode. The power management chip 313 is responsible for stabilizing, distributing, and protecting the DC power from the power supply module 40. The circuit control board 311 is fixed inside the oxygen generation core module 10. In terms of spatial layout, the circuit control board 311 and the gas storage box 131 are arranged side by side in the horizontal direction. Both are located on the top plane of the oxygen generation core module 10. The gas storage box 131 is located in the central area, and the circuit control board 311 is located on the side of the oxygen generation core module 10, which facilitates the connection and maintenance of signal cables.

[0061] The sensing unit 32 further includes an oxygen concentration sensor 321, a temperature sensor 322, and a pressure sensor 323. In some optional embodiments, the oxygen concentration sensor 321 can be implemented as a miniature electrochemical sensor, electrically connected to the analog input port of the circuit control board 311. The probe end of the oxygen concentration sensor 321 is installed near the outlet of the gas storage box 131 to detect the concentration of output oxygen in real time. When the detected oxygen concentration is lower than a preset threshold, such as 85%, the microprocessor 312 triggers an alarm, thereby ensuring that the output oxygen quality meets the usage requirements. In some optional embodiments, the pressure sensor 323 is a miniature piezoresistive pressure sensor, directly exposed inside the gas storage box 131, detecting the oxygen pressure inside the gas storage box. Its leads are also connected to the circuit control board 311 to monitor the pressure inside the gas storage box in real time and adjust the compressor's operating intensity accordingly.

[0062] like Figure 1As shown, the human-machine interface unit 33 includes an LED status indicator 331, a buzzer 332, and an operation button 333. In this embodiment, the wearable oxygen generator system also includes an integrated interaction and output unit located on the upper front side of the wearable garment 611. This interaction and output unit integrates human-machine interaction functions and gas output functions. Specifically, the integrated interaction and output unit includes a power switch and an oxygen output interface 621. The power switch can be activated by the operation button 333, which is located on the panel of the integrated unit and electrically connected to the input port of the circuit control board 311. Users can turn the device on or off by short pressing and switch the working mode by long pressing. The LED status indicator 331 is a multi-color LED, also located on the panel of the integrated unit, and connected to the output port of the circuit control board 311 via a wire. It can display green for normal operation, yellow for low battery, and red for fault alarm. The buzzer 332 is fixed near the circuit control board 311 or the inner layer of the wearable garment 611 and emits an audible alarm when the system detects an abnormality.

[0063] The oxygen output interface 621 is located on the interaction and output unit, using a standard medical quick connector. It is connected to the outlet of the gas storage box 131 via a product oxygen output pipeline laid out in the wiring channel 613. The product oxygen output pipeline is used to deliver finished oxygen from the self-made oxygen core module 10 to the oxygen output interface 621. The oxygen output interface 621 integrates a one-way valve 623 to prevent backflow of exhaled gas or external contaminants. Users can connect the nasal cannula 622 to the oxygen output interface 621 for oxygen inhalation. Because the interaction and output unit is located in the upper front area of ​​clothing, such as the chest or shoulder, users can easily operate the power switch, observe the device's operating status indicators, and connect or disconnect the nasal cannula without removing their clothing while wearing the device. This greatly improves the convenience of use and the user-friendliness of the human-computer interaction, achieving the goal of "ready to use after wearing".

[0064] In some optional embodiments, the power supply module 40 includes an energy storage unit 41 and a power management unit 42. The energy storage unit 41 includes a battery 411 and a charging interface 412. The battery 411 is encapsulated in a protective hard shell and secured to a fourth internal pocket 612 on the side of the waist or below the back using Velcro or elastic straps. The charging interface 412 is located at the outer hem or side waist of the clothing 611 and is connected to the charging management circuit of the battery 411 via a power cable, supporting external power charging. In some embodiments, it supports simultaneous charging and use.

[0065] The power management unit 42 includes a battery protection board 421, which integrates overcharge protection, over-discharge protection, overcurrent protection, short circuit protection, and temperature protection circuits. It is connected in series with the output of the battery 411. The output of the battery protection board 421 is electrically connected to the power input of the circuit control board 311, where the power management chip 313 regulates and distributes the voltage, supplying power to the compressor 211, cooling fan 511, the circuit control board 311 itself, and various sensors. The battery protection board 421 also integrates a power detection circuit, which can calculate the remaining power percentage in real time and transmit the data to the microprocessor 312 via signal lines. The data is then displayed in different colors by LED status indicator lights 331, providing the user with an intuitive power level indication.

[0066] like Figure 1 As shown, the garment 611 also includes a structural support unit 63, which includes flexible support strips disposed at key parts of the garment 611. These support strips are used to prevent excessive deformation of the garment after it is installed in the module, maintain its crisp appearance, and provide cushioning protection for the internal components. These flexible support strips are arranged along the shoulders, back center line, and waist of the garment, which are areas subject to greater stress, thereby enhancing the overall structural stability.

[0067] During system operation, after the user puts on the clothing 611, they press the power switch located on the interaction and output unit in the upper front area, and the circuit control board 311 powers on and performs a self-test. The microprocessor 312 first checks the battery 411's charge level. If the charge is sufficient, for example, greater than or equal to 20%, it then checks the feedback data from the pressure sensor 323, temperature sensor 322, and oxygen concentration sensor 321. If all are within the normal range, the LED status indicator 331 displays green, and the system enters the operating state.

[0068] The microprocessor 312 sends a start signal to the drive circuit of the compressor 211, and the compressor 211 begins to operate. Outside air enters through the air inlet 2211 at the bottom of the garment 611, passes through the air filter 222 and the dustproof and breathable membrane 223 in sequence, and enters the air inlet of the compressor 211. The compressor 211 compresses the air and delivers it from the air outlet through the air connection pipe 123 to the air inlet of the air circuit integration unit 12.

[0069] When compressed air enters the gas channel 1212 inside the gas path integration unit 12, according to the control signal of the microprocessor 312, the solenoid valve in the lower gas path assembly 122 opens the gas path leading to the first molecular sieve barrel 1111 located in the front area. The compressed air is delivered from the back to the left side of the chest along the waist area through the compressed air supply pipeline laid in the wiring channel 613, and enters the first molecular sieve barrel 1111. Under pressurization, nitrogen in the air is adsorbed by the molecular sieve material 112, while oxygen passes through the molecular sieve bed and flows out from the outlet of the first molecular sieve barrel 1111. It then returns to the gas path integration unit 12 on the back along the waist area through the oxygen-enriched gas return pipeline laid in the wiring channel 613, and enters the gas storage box 131 through the oxygen collection channel inside. At this time, the second molecular sieve barrel 1112 is in a desorption and regeneration state. The corresponding exhaust valve in the lower air passage assembly 122 opens, the internal pressure of the second molecular sieve barrel 1112 decreases, and the previously adsorbed nitrogen gas desorbs from the molecular sieve and returns to the lower air passage assembly 122 on the back through the pipeline in the wiring channel 613. It is then discharged through the exhaust channel and finally discharged to the external environment through the exhaust port reserved in the clothing 611. In an optional embodiment, the wiring channel 613 is laid out from the reserved opening on the side wall of the first pocket in the back area, extends horizontally along the waist side seam of the clothing 611 to the front area, and has branch interfaces at the second and third pockets on the left and right sides of the chest, with a total length of approximately 400 to 600 mm. At the connection between the wiring channel 613 and each pocket, the channel opening is fixed to the inner wall of the pocket by heat fusion bonding or stitching reinforcement to form a sealed transition structure and prevent the pipeline from shifting or falling off during wearing activities. The wiring channel 613 contains three types of pipelines: from bottom to top, they are compressed air supply pipeline, oxygen-enriched gas return pipeline, and product oxygen output pipeline. The three types of pipelines are fixed in layers inside the channel to avoid mutual interference and wear. This achieves complete concealment of the gas circuit connection, eliminates the risk of entanglement and snagging caused by exposed pipelines in traditional portable oxygen concentrators, and significantly improves the safety and aesthetics of wearing the device.

[0070] After a preset time period, typically 2 to 6 seconds, the microprocessor 312 controls the solenoid valves within the gas path assembly 122 to switch, closing the inlet valve to the first molecular sieve barrel 1111 and opening the inlet valve to the second molecular sieve barrel 1112, while simultaneously switching the first molecular sieve barrel 1111 to the desorption state. At this time, compressed air is delivered to the second molecular sieve barrel 1112 on the right side of the chest through the compressed air supply pipeline in the wiring channel 613. The second molecular sieve barrel 1112 begins to adsorb and produce oxygen, while the first molecular sieve barrel 1111 undergoes regeneration. The two molecular sieve barrels 111 alternate in this cycle, achieving continuous oxygen output and ensuring a stable oxygen supply for the user.

[0071] The generated oxygen-enriched gas continuously flows through the oxygen-enriched gas return pipeline in the wiring channel 613 and converges into the gas storage box 131 located at the back. The gas storage box 131 buffers the airflow through its internal volume, smoothing out the pressure fluctuations and flow pulsations caused by the instantaneous switching of the molecular sieve. The pressure sensor 323 monitors the pressure inside the gas storage box 131 in real time. When the pressure reaches a preset upper limit, such as 8,000 to 10,000 kPa gauge pressure, the microprocessor 312 can briefly reduce the operating frequency of the compressor 211 or stop the gas intake to prevent overpressure; when the pressure drops to a lower limit, such as 2,000 to 3,000 kPa gauge pressure, the operating intensity of the compressor 211 is restored or increased to ensure stable output pressure, thereby achieving precise control of the output oxygen pressure.

[0072] The finished oxygen stored in the gas storage box 131 is delivered through the gas outlet on the side of the gas storage box 131, through the finished oxygen output pipeline laid in the wiring channel 613, and upwards along the inside of the clothing 611 to the oxygen output interface 621 on the front upper area of ​​the interaction and output unit. The user inhales oxygen through the nasal cannula 622 from the oxygen output interface 621. The one-way valve 623 ensures that the user's exhaled gas does not flow back into the gas storage box 131, thereby ensuring the hygiene and safety of the system.

[0073] The oxygen concentration sensor 321 continuously monitors the output oxygen concentration. In this embodiment, when the molecular sieve material 112 is in good condition and the system is working normally, the output oxygen concentration should remain stable at a high level. If the oxygen concentration sensor 321 detects a concentration lower than a preset threshold, such as 85%, it indicates that there may be problems such as aging of the molecular sieve material 112, blockage of the air filter 222, or gas leakage. The microprocessor 312 immediately triggers an alarm, the LED status indicator 331 flashes red, and the buzzer 332 emits an intermittent beeping sound, reminding the user to stop using the device and perform an inspection, thereby ensuring user safety.

[0074] During system operation, temperature sensor 322 continuously monitors the casing temperature of compressor 211. When the temperature exceeds an upper threshold temperature, such as 55 degrees Celsius, microprocessor 312 sends a start signal to cooling fan 511. Cooling fan 511 begins to rotate, blowing airflow from a position above the oxygen generation core module 10. The airflow is directed towards compressor 211, flowing vertically downwards over the casing of air storage box 131 and the surface of air path integration unit 12, finally reaching the surface of compressor 211's casing, where forced convection removes heat. The heated air continues to be guided upwards along air duct structure 512, and is exhausted to the outside through a breathable network in the area above the back of the clothing 611. When temperature sensor 322 detects that the temperature has dropped below a lower threshold temperature, such as 45 degrees Celsius, cooling fan 511 automatically stops and enters standby mode. This temperature control cycle is performed automatically throughout the entire operation without user intervention, thus achieving intelligent management of system temperature.

[0075] The battery protection board 421 monitors the voltage and current of the battery 411 in real time and calculates the remaining power. For example, when the power drops to 30%, the LED status indicator 331 changes from green to yellow to remind the user to pay attention to the power level; when the power drops to 10%, the yellow indicator flashes and is accompanied by a short beep; when the power drops to 5% or the voltage is below the protection threshold, the battery protection board 421 automatically cuts off the output, and the system stops working to prevent the battery from being damaged by over-discharge. The user can connect an external charger through the charging interface 412 for charging. In some embodiments, it supports continuing to use the device while charging, thereby ensuring the continuous availability of the device.

[0076] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
