Description

Technical Field

[0001] This invention relates to the field of pressurized oxygen supply equipment technology, specifically to a portable intelligent integrated pressurized oxygen supply device that is resistant to altitude sickness. Background Technology

[0002] With the increase in high-altitude tourism, mountaineering and exploration, and high-altitude work activities, altitude sickness has become a key concern affecting human health, mood, and the safety and comfort of activities. The core characteristics of the high-altitude environment are high altitude, low atmospheric pressure, and low oxygen content. When a person enters this environment, their lungs can only expand to about 70% of the normal range, resulting in insufficient lung compression during inhalation. The inhaled air volume is only about 70% of that at sea level. At the same time, the oxygen content at an altitude of about 3,400 meters is only 62.8% of that at sea level, and even drops to 42% at higher altitudes. This results in low oxygen partial pressure and low blood oxygen levels, making people prone to altitude sickness symptoms such as headache, nausea, dizziness, and high-altitude pulmonary / cerebral edema.

[0003] Current solutions for high-altitude hypoxia primarily focus on simply increasing the concentration of inhaled oxygen, such as various portable oxygen cylinders, chemical oxygen generators, and nasal mask oxygen supply devices. These devices merely introduce oxygen into the inhalation pathway and cannot alter the environmental pressure within the mask or respiratory tract. Therefore, they are ineffective in addressing the inherent physiological disorders caused by low air pressure, such as insufficient lung expansion and fluid imbalances that impair oxygenation. On the other hand, while hyperbaric oxygen chambers can provide both high pressure and high oxygen levels, their large size and fixed usage scenarios make their implementation in mobile applications such as mountaineering, patrolling, disaster relief, engineering construction, and transportation virtually impossible. Furthermore, most existing wearable oxygen supply devices only cover the mouth and nose, leaving the ears exposed to the low air pressure. This makes it difficult to balance the pressure difference between the middle ear and the outside, often resulting in accompanying symptoms such as ear pain, hearing loss, and eardrum perforation. Additionally, they lack overall pressure protection for the head area.

[0004] The structure of a fully enclosed, sealed headgear / helmet covering the mouth, nose, and ears has long been a mature application in the aerospace and diving fields. High-altitude compensatory helmets (such as the sealed helmets used by some fighter pilots) achieve airtight sealing of the head space through an inflatable sealing ring at the neck and an inflatable bladder-type face window, and work with the compensatory suit to maintain a pressurized environment around the body. Diving full-face masks or helmets completely isolate the breathing space from water through a neck seal or a one-piece drysuit structure. However, the design starting point of these two types of equipment is different from that of this invention: the sealing calculation of aerospace sealed helmets is based on millisecond-level cockpit depressurization backup, often at the cost of extremely high neck tightening force and overall linkage with the torso compensatory suit. Pilots wearing them have severely restricted their movement and require a continuous external compressed air supply system, making them unportable; diving helmets, on the other hand, do not need to cope with "low-pressure" environments at all. Their structural focus is on watertightness and pressure resistance, and they also rely on an external air supply umbilical cord or heavy-duty gas cylinder system. Their control strategy does not involve pressurization adjustment for high-altitude low-pressure environments. Summary of the Invention

[0005] The purpose of this invention is to provide a portable intelligent pressurized oxygen supply device for altitude sickness, which achieves dynamic adjustment of oxygen and pressure supply through a fully enclosed system to overcome the shortcomings of existing altitude sickness equipment.

[0006] This invention provides a portable intelligent pressurized oxygen supply device for altitude sickness, including a storage backpack and a breathing module. The storage backpack contains an electrically connected power module and a control module. The breathing module includes a sealed cavity, a pressurized air intake pipe connected to the sealed cavity, an air outlet pipe on the sealed cavity, and an airbag-type seal on the inner side of the sealed cavity. The storage backpack also contains an oxygen generation module and a buffer chamber. The oxygen generation module is connected to the buffer chamber via a second one-way valve. The buffer chamber is connected to the booster intake pipe through a third pressure control valve, and a booster pump is installed on the buffer chamber to increase the internal pressure of the buffer chamber. The buffer chamber is connected to a sealed air inlet pipe via a first pressure control valve for providing air pressure compensation for the airbag-type seal; One output end of the oxygen storage cylinder is connected to the buffer chamber through the first one-way valve, and the other output end of the oxygen storage cylinder is connected to the oxygen supply pipe through the adjustable solenoid valve. The oxygen supply pipe is connected to the inside of the sealed cavity. The sealed cavity is equipped with an environmental monitoring unit and a physiological sign monitoring unit. The environmental monitoring unit is configured to collect at least one of the O2 concentration, CO2 concentration and air pressure in the sealed cavity, and the physiological sign monitoring unit is configured to collect the wearer's vital signs. The control module is electrically connected to the oxygen generation module, the booster pump and the power module, and is configured to adjust the gas supply parameters of the booster pump and the oxygen generation module in a coordinated manner based on the feedback signals of the collected data, so as to achieve dynamic adjustment of the target pressure and oxygen concentration level in the sealed environment.

[0007] Existing high-pressure anti-rebound masks mostly use a single-layer airbag or silicone lip to fit the face. This type of single-stage seal is prone to partial detachment when the user moves, speaks, or changes facial expressions, resulting in insufficient seal redundancy. Some solutions increase pre-pressure to improve the sealing effect, which exacerbates facial indentation and discomfort. Therefore, this invention provides an intelligent integrated device that can provide zoned pressure sealing for areas including the mouth, nose, and ears while being portable and wearable, and can coordinately adjust the pressure and oxygen supply according to vital signs and internal environmental parameters to solve the defects of the existing technology.

[0008] Specifically: The breathing module in this technical solution provides pressurized oxygen to the wearer while ensuring a tight seal, and provides matching air pressure and oxygen supply according to the wearer's movements and altitude changes; the multiple air paths, booster pump, oxygen generation module, power supply module, oxygen storage cylinder, and control module in the storage backpack provide support for dynamic adjustment of oxygen and pressure supply in a relatively closed environment; the booster pump is used to control the pressure of the booster intake pipe, enabling the air supply system to provide gas with an equivalent air pressure of no less than 1800 meters altitude to the sealed breathing module in the low-pressure environment of high altitude, thereby increasing the wearer's blood oxygen concentration and ensuring fluid balance and normal oxygen partial pressure; The oxygen storage cylinder has two output terminals, each equipped with a first one-way valve and an adjustable solenoid valve. When the oxygen generation module and the entire system fail simultaneously, the oxygen storage cylinder can serve as a backup gas source, ensuring unobstructed gas supply to the breathing module via the adjustable solenoid valve and oxygen supply tube. When the power of the oxygen generation module decreases and the airflow in the buffer chamber is insufficient to support the supply of inflatable components such as the sealing airbag, the oxygen storage cylinder can inject new gas into the buffer chamber through the first one-way valve. In particular, when the inhalation volume exceeds the maximum output threshold of the booster pump and oxygen generation module during strenuous exercise, the oxygen cylinder can also provide gas source compensation to the buffer chamber, enabling the device to flexibly switch between pressurization and oxygen supply modes in different usage scenarios, and to continuously pressurize and supply gas. Preferably, both output ends of the oxygen storage cylinder in this technical solution are equipped with corresponding one-way flow and pressure regulating valves to ensure that the gas source output to the oxygen supply pipe or buffer chamber can be directly used by the wearer; wherein, the adjustable solenoid valve refers to a valve that can automatically open when the power is off, so that the oxygen storage cylinder can directly ensure oxygen supply through the oxygen supply pipe after the failure of the entire system, further increasing the safety redundancy of the system.

[0009] Furthermore, the airbag seal on the breathing module features a two-stage sealing structure, effectively isolating the wearer from the outside environment. Corresponding environmental and physiological monitoring units monitor various data points related to the wearer's zoned pressure seal (such as oxygen content, carbon dioxide content, and air pressure), transmitting these data in real-time to a control module located within the storage backpack. The control module analyzes and compares the real-time data with preset thresholds, then issues corresponding adjustment commands, such as adjusting air pressure or oxygen supply. To ensure flexibility in adjusting each air intake line, this technical solution includes a buffer chamber with a corresponding oxygen generation module. The oxygen generated in the oxygen generation module first accumulates in the buffer chamber through a second one-way valve. When the oxygen supply inside the sealed chamber decreases and the air pressure changes, a third pressure control valve is used to increase the oxygen supply and pressure within the sealed chamber. The first pressure control valve adjusts the airflow from the buffer chamber to the sealed air intake line, thereby adjusting the sealing strength of the two-stage seal within the airbag seal in real-time.

[0010] The airbag-type sealing component includes a T-shaped partition plate and a U-shaped fixing frame. The fixing frame has a through hole in the middle. The horizontal section of the partition plate is placed on the outer wall of the fixing frame, and the vertical section of the partition plate moves through the through hole and connects to the silicone pad used to wrap the area to be sealed for the wearer. A sealing airbag is provided in the gap between the partition plate and the fixing frame, and the output end of the sealing air inlet pipe is connected to the sealing airbag. Furthermore, as a key component for the independent partition sealing of the sealing cavity in this technical solution, the airbag-type seal includes a U-shaped fixing frame fixed on the sealing cavity. The U-shaped space inside the fixing frame is divided into two by a partition plate, providing expansion and contraction space for the two sealing airbags. In the initial state, there is a certain gap between the horizontal section of the partition plate and the outer wall of the fixing frame. That is, when the sealing airbag is not inflated, the silicone pad has a certain amount of movement. When the sealing airbag is inflated, it expands in the U-shaped space and then pushes against the outer wall of the silicone pad until the silicone pad adheres to the surface to be sealed on the wearer. The two sealing airbags adjust the air intake through the first air intake control valve and the second air intake control valve, respectively, to meet the dual redundancy sealing requirements when the wearer walks or performs actions, effectively preventing gaps from forming between the sealing area of ​​the sealing cavity and the coverage area of ​​the wearer.

[0011] The sealed cavity includes a shell for wrapping the wearer’s entire head and having a neck opening, and a face window on the shell; the airbag-type seal is located at the neck opening to form an airtight seal around the wearer’s neck when worn, and a fastening airbag is provided inside the shell, with an airbag inlet pipe on the fastening airbag, which is connected to the buffer chamber through a second pressure control valve. Furthermore, the sealed cavity in this technical solution adopts a helmet-style full-coverage structure. By setting a face window on the shell to ensure the wearer's normal field of vision, multiple securing airbags can be set inside the shell, corresponding to the top and back of the wearer's head respectively. That is, by controlling the amount of air injected into the securing airbags through the airbag inlet tube, the inner wall of the shell can be matched with wearers of different head sizes. Under the premise of achieving a fit between the entire sealed cavity and the wearer, the securing airbags can also provide a corresponding cushioning effect, avoiding gaps between the silicone pad and the wearer's contact surface. The airbag seal is set at the neck opening. The two sealing airbags in the airbag seal have a real-time pressure detection function, and effectively coordinate with the air intake of the pressurized air inlet tube, the pressure inside the shell, and the oxygen concentration inside the shell. That is, while ensuring the wearer's neck comfort (the pressure range generated by the expansion of the sealing airbag is 0.41~1kPa, and this pressure value increases with the increase of altitude), effective isolation between the inside of the shell and the outside world is ensured. Specifically, when the pressure data inside the two sealed airbags is fed back to the control module, the control module issues a command to drive the oxygen generation module, the booster pump and the oxygen storage cylinder to make dynamic adjustments. At the same time, the exhaust control valve on the sealed airbag works in sync with the second pressure control valve to make corresponding intake and exhaust adjustments until the sealing effect of the sealed airbag and the silicone gasket together reaches a leakage value of ≤0.5%.

[0012] The sealed cavity includes a mouth and nose mask, an adjustable connector, and two earmuffs. The mouth and nose mask is used to cover the wearer's mouth and nose; the two earmuffs are used to cover the wearer's ears respectively; the adjustable connector is used to connect the mouth and nose mask and the two earmuffs and can adjust the relative positions of the three; wherein, there are 3 airbag-type sealing elements, which are respectively set at the wearing contact edges of the mouth and nose mask and the wearing contact edges of the two earmuffs. Furthermore, in this technical solution, the sealing cavity adopts a cover-type structure, corresponding to the wearer's mouth and nose and two ears respectively. Adjustable connectors are used to detachably fix the mouth and nose mask and two earmuffs to the wearer's head. Three airbag-type sealing elements are set on the sealing cavity, covering the wearer's mouth and nose and two ears respectively. The airbag-type sealing elements of the two ears and the mouth and nose are provided with the same air intake pipe, and the air intake volume is adjusted by the air intake control valve to achieve independent sealing of the zones. Specifically, the sealing air intake pipe is divided into three bypasses, each corresponding to three independent zone sealing areas. Each bypass is further subdivided into two groups of branches, and the air intake volume of the two sealing airbags is controlled by the first air intake control valve and the second air intake control valve at the end of the two groups of branches respectively.

[0013] The sealed cavity includes a mask body and an adjustable connector. Earmuffs are located on both sides of the mask body, and a face window is located on the front of the mask body. The mask body has an outer peripheral edge that matches the wearer's facial contours. Three airbag-type sealing elements are located at the outer peripheral edge and the wearing contact edges of the two earmuffs, respectively. The adjustable connector connects the mask body to the two earmuffs and allows adjustment of their relative positions. Furthermore, in this technical solution, the sealed cavity adopts a mask-style structure, corresponding to the wearer's face and ears respectively. The adjustable connector detachably fixes the mask body and the two earmuffs to the wearer's desired positions. In this technical solution, the airbag seals at the outer peripheral edge ensure a tight seal between the mask body and the face, while the airbag seals at the two earmuffs ensure independent airtightness in the ear areas. The adjustable connector allows wearers with different head shapes to adjust the mask body and earmuffs to the optimal fit, reducing uneven sealing caused by individual differences.

[0014] The environmental monitoring unit includes an O2 concentration sensor, a CO2 concentration sensor, and a pressure sensor; the physiological sign monitoring unit includes a vital sign sensor. Preferably, the O2 concentration sensor, CO2 concentration sensor, and pressure sensor can transmit environmental parameters within the sealed cavity to the control module in real time, while the vital sign sensor can transmit the wearer's vital sign parameters to the control module in real time. The collected data is fused and processed by the control module and used as the basis for the coordinated adjustment of the booster pump power, oxygen generation module, oxygen output from the oxygen storage cylinder, and the opening degree of each control valve, thus forming a complete environmental-physiological closed-loop system.

[0015] An automatic pressure relief valve connected to the airbag is also provided on the outside of the sealed cavity. Preferably, to facilitate user flexibility, an automatic pressure relief valve for controlling the automatic decompression of the airbag is provided on the outside of the sealed cavity, and a slow-release pressure relief button that works in conjunction with the automatic pressure relief valve is provided on the outer wall of the sealed cavity. A single press allows for continuous pressure relief of the airbag. Furthermore, a manual slow-release pressure relief valve connected to the airbag can also be provided on the outside of the sealed cavity for manual pressure relief in emergency situations.

[0016] A pressure sensor is installed inside the sealed airbag, and the pressure sensor is electrically connected to the control module. Preferably, the two sealed airbags in the same sealed area are a first sealed airbag and a second sealed airbag, respectively. A first pressure sensor is installed in the first sealed airbag, and a second pressure sensor is installed in the second sealed airbag. The two pressure sensors can transmit their internal pressure values ​​to the control module in real time. In extreme cases, if one of the two sealed airbags in the independent sealed area ruptures or leaks, the control module will promptly control the booster pump to increase the air intake into the sealed cavity to temporarily maintain the relative air pressure balance inside the sealed cavity. At the same time, it will also issue a warning to the wearer so that the wearer can take emergency measures in time.

[0017] The adjustable connector includes a cover plate and multiple adjustable webbing straps. A fastening airbag is located on the inner wall of the cover plate. The multiple adjustable webbing straps are connected to the sealed cavity, and multiple buckles that mate with the adjustable webbing straps are located on the outer edge of the cover plate. The fastening airbag has an airbag inlet tube, which is connected to the buffer chamber via a second pressure control valve. Furthermore, in this technical solution, the wearer's top of the head and the back of the head are exposed. One function of the adjustable connector is to ensure the stability of the breathing module when worn. Simultaneously, by injecting air into the fastening airbag through the airbag inlet tube, it ensures the fit and comfort between the cover plate and the exposed area of ​​the wearer's head. Together with the matching buckles and adjustable webbing straps, it facilitates compatibility with wearers of different head shapes or sizes.

[0018] The cover plate includes an upper cover that matches the wearer's skull top region and a lower cover that matches the wearer's back head region. The upper and lower covers are connected to each other, and both upper and lower covers have securing airbags on their inner sidewalls. The airbag inlet pipes have two branches, each connected to one of the two securing airbags. Preferably, the purpose of the segmented cover plate design is to increase the pressure points of the breathing module, which can greatly improve the wearer's comfort. At the same time, the upper and lower covers are made of carbon fiber, which reduces the weight of the entire breathing module while ensuring its damage resistance. The securing airbags on the upper and lower covers are supplied with air through the two branches of the airbag inlet pipes, ensuring the independence of the two securing airbags. Furthermore, the two securing airbags are equipped with exhaust solenoid valves electrically connected to the control module, which can realize depressurization when the wearer removes the breathing module.

[0019] The sealed cavity is also equipped with a communication module and a positioning module. Preferably, the communication module includes Bluetooth, which enables interconnection and group communication with the wearer's mobile terminal; the positioning module enables real-time location tracking of the wearer.

[0020] The storage backpack is also equipped with an integrated tube, within which the exhaust pipe, pressurized intake pipe, oxygen supply pipe, and sealed intake pipe are housed. An exhalation valve is provided on the exhaust pipe. Preferably, the exhaust pipe, pressurized intake pipe, oxygen supply pipe, sealed intake pipe, and matching detection and data transmission cables are bundled together via the integrated tube to simplify wiring, reduce exposed pipe area, and extend their service life. Furthermore, the exhaust pipe utilizes an exhalation valve to discharge exhaled gas, preventing backflow. An inhalation valve is provided at the end of the pressurized intake pipe and oxygen supply pipe. Both the exhalation and inhalation valves are adjustable, meaning they can adjust their unit flow rate in real time according to different altitudes and varying inhalation and exhalation pressures.

[0021] The storage backpack is also equipped with a solar panel, which is used to charge the power module. Preferably, the solar panel is used to supplement the power module with electricity, etc., which can be flexibly selected according to the usage scenario to improve the device's endurance in outdoor, high-altitude, and other environments without external power sources.

[0022] Compared with the prior art, the present invention has the following advantages and beneficial effects: (1) The airbag sealing component set on the breathing module of the present invention is a two-level sealing structure, which can effectively isolate the wearer from the outside world. The corresponding environmental monitoring unit and physiological sign monitoring unit monitor the various data of the wearer's partition pressure sealing and send them to the control module located in the storage backpack in real time. The control module analyzes and compares the differences between each real-time data and its preset threshold, and then makes corresponding adjustment commands, such as whether to adjust the air pressure value or oxygen supply. (2) In this invention, the U-shaped fixed frame is divided into two by a retractable partition plate, and sealing airbags are set in the two separated areas respectively. The silicone pad connected to the end of the partition plate is extended and retracted by the air intake and exhaust of the two sealing airbags. The air intake of the two sealing airbags is adjusted by the first air intake control valve and the second air intake control valve respectively, so as to meet the double redundancy sealing requirements when the wearer walks normally or performs actions, and effectively prevent gaps from being generated between the sealing area of ​​the sealing cavity and the coverage area of ​​the wearer. (3) In this invention, the buffer chamber can buffer the volume and balance the pressure of the gas supplied from the booster pump and the oxygen generation module, regulate the oxygen concentration of the mixed gas, reduce the pressure and mixed gas volume fluctuations generated during the gas supply process, reduce the breathing resistance at the moment of inhalation and the compensation when the breathing frequency and breathing volume increase during strenuous exercise, and improve safety redundancy and wearing comfort.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments and accompanying drawings. The illustrative embodiments and descriptions of this invention are for illustrative purposes only and are not intended to limit the invention. It should be noted that the product of this invention is already in the actual research and development stage.

[0025] Example 1: like Figures 1 to 9 As shown, this embodiment includes: The system includes a storage backpack 1 and a breathing module 2. The storage backpack 1 contains an oxygen storage cylinder 102, a power module 104, and a control module 106, which are electrically connected. The breathing module 2 includes a sealed cavity 32, a pressurized air inlet pipe 26 connected to the sealed cavity 32, an air outlet pipe 6 on the sealed cavity 32, and an airbag-type seal 25 on the inner side of the sealed cavity 32. The storage backpack 1 is also equipped with an oxygen generation module 101 and a buffer chamber 5. The oxygen generation module 101 is connected to the buffer chamber 5 through a second one-way valve 108. The buffer chamber 5 is connected to the booster intake pipe 26 through the third pressure control valve 111, and the buffer chamber 5 is equipped with a booster pump 103 for increasing the internal pressure of the buffer chamber 5. The buffer chamber 5 is connected to the sealed air inlet pipe 29, which provides air pressure compensation for the airbag seal 25, via the first pressure control valve 109. One output end of the oxygen storage cylinder 102 is connected to the buffer chamber 5 through the first one-way valve 107, and the other output end of the oxygen storage cylinder 102 is connected to the oxygen supply pipe 36 through the adjustable solenoid valve 105. The oxygen supply pipe 36 is connected to the inside of the sealed cavity 32. The sealed cavity 32 is equipped with an environmental monitoring unit 7 and a physiological sign monitoring unit. The environmental monitoring unit 7 is configured to collect at least one of the O2 concentration, CO2 concentration and air pressure inside the sealed cavity 32, and the physiological sign monitoring unit is configured to collect the wearer's vital signs. The control module 106 is electrically connected to the oxygen generation module 101, the booster pump 103 and the power module 104, and is configured to adjust the gas supply parameters of the booster pump 103 and the oxygen generation module 101 in a coordinated manner based on the feedback signal of the collected data, so as to achieve dynamic adjustment of the target pressure and oxygen concentration level in the sealed environment.

[0026] In this embodiment, the airbag seal 25 set on the breathing module 2 is a two-stage sealing structure, which can effectively isolate the wearer from the outside world. The corresponding environmental monitoring unit 7 and physiological sign monitoring unit monitor various data of the wearer's zoned pressure seal and send them to the control module 106 located in the storage backpack 1 in real time. The control module 106 analyzes and compares the differences between each real-time data and its preset threshold, and then makes corresponding adjustment commands, such as whether to adjust the air pressure value or oxygen supply.

[0027] To achieve flexibility in adjusting each air intake pipe, this embodiment includes a buffer chamber 5, with a corresponding oxygen generation module 101. The oxygen generated in the oxygen generation module 101 first accumulates in the buffer chamber 5 through the second one-way valve 108. When the oxygen supply inside the sealed cavity 32 decreases and the air pressure changes, the third pressure control valve 111 is used to increase the oxygen and pressure in the sealed cavity 32. The first pressure control valve 109 can adjust the air intake volume from the buffer chamber 5 to the sealed air intake pipe 29, and adjust the sealing strength of the two-stage seal within the airbag seal 25 in real time. The buffer chamber 5 can buffer the volume and balance the pressure of the air supplied from the booster pump 103 and the oxygen generation module 101, and regulate the oxygen concentration of the mixed gas. This reduces pressure and mixed gas volume fluctuations during the air supply process, reduces breathing resistance at the moment of inhalation and compensation during increased breathing frequency and volume during strenuous exercise, and improves safety redundancy and wearing comfort.

[0028] As a key component for the zoned sealing of the sealing cavity 32 in this embodiment, the airbag-type sealing element 25 includes a T-shaped partition plate 27 and a U-shaped fixing frame 28. The fixing frame 28 has a through hole in the middle. The horizontal section of the partition plate 27 is placed on the outer wall of the fixing frame 28, and the vertical section of the partition plate 27 moves through the through hole and connects to the silicone pad 14 used to wrap the area to be sealed for the wearer. A sealing airbag 8 is provided in the gap between the partition plate 27 and the fixing frame 28, and the output end of the sealing air inlet pipe 29 is connected to the sealing airbag 8. The fixed frame 28 is divided into two by a partition plate 27, and sealing airbags 8 are set in the two separated areas. The silicone pad 14 connected to the end of the partition plate 27 expands and contracts through the air intake and exhaust of the two sealing airbags 8. The air intake of the two sealing airbags 8 is adjusted by a first air intake control valve 203 and a second air intake control valve 204, respectively, to meet the double redundancy sealing requirements when the wearer walks or performs actions, effectively preventing gaps between the sealing area of ​​the sealing cavity 32 and the wearer's coverage area. It should be noted that the airbag-type seal 25 in this embodiment is placed inside the sealing cavity 32 and is not directly exposed to the outside. The gap between the two sealing airbags 8 and the silicone pad 14 is filled after the sealing airbags 8 are inflated. Figure 7 The image shows the state of the airbag 8 when it is inflated. Figure 8 and Figure 9 This is the state when the airbag is deflating.

[0029] Preferably, the environmental monitoring unit 7 includes an O2 concentration sensor, a CO2 concentration sensor 13, and a pressure sensor 21; the physiological sign monitoring unit includes a vital sign sensor 20; the O2 concentration sensor, CO2 concentration sensor 13, and pressure sensor 21 can transmit environmental parameters within the sealed cavity 32 to the control module 106 in real time, while the vital sign sensor 20 can transmit the wearer's vital sign parameters to the control module 106 in real time. The collected data is fused and processed by the control module 106 and used as the basis for the coordinated adjustment of the power of the booster pump 103, the oxygen generation module 101, the oxygen output of the oxygen storage cylinder 102, and the opening degree of each control valve, thus forming a complete environmental-physiological closed-loop system.

[0030] As a preferred option, to facilitate the wearer's flexibility of use, an automatic pressure relief valve 18 is provided on the outside of the sealed cavity 32 to control the automatic decompression of the sealed airbag 8, and a slow-release pressure relief button that cooperates with the automatic pressure relief valve 18 is provided on the outer wall of the sealed cavity 32. By pressing the button, the continuous pressure relief of the sealed airbag 8 can be achieved.

[0031] Preferably, the two sealing airbags 8 within the same sealed area are a first sealing airbag 201 and a second sealing airbag 202, respectively. A first pressure sensor 205 is installed in the first sealing airbag 201, and a second pressure sensor 206 is installed in the second sealing airbag 202. The two pressure sensors can transmit their internal pressure values ​​to the control module 106 in real time. In extreme cases, if one of the two sealing airbags 8 in the sealed area ruptures or leaks, the control module 106 will promptly control the booster pump 103 to increase the air intake into the sealed cavity 32 to temporarily maintain the relative balance of air pressure inside the sealed cavity 32. At the same time, it will also issue a warning to the wearer so that the wearer can take emergency measures in time.

[0032] This embodiment includes three different types of breathing modules 2, the specific difference being the choice of sealing cavity 32. One is a partial wrapping structure for the mouth, nose and ears, the second is a partial wrapping structure for the face mask, and the third is a full wrapping structure for the helmet. The airbag-type sealing element 25 in the three types has the same specific structure, only the setting position is different. Except for the full wrapping type, the remaining two types of sealing cavities 32 are equipped with adjustable connectors with the same structure for fitting and fastening between the sealing cavity 32 and the wearer's head. The adjustable connector includes a cover plate and multiple adjustable webbing 22. A fastening airbag 30 is provided on the inner wall of the cover plate. The multiple adjustable webbing 22 are respectively connected to the sealed cavity 32. Multiple buckles 23 that cooperate with the adjustable webbing 22 are provided on the outer edge of the cover plate. The fastening airbag 30 is provided with an airbag inlet pipe 31, which is connected to the buffer chamber 5 through a second pressure control valve 110. The wearer's skull and back of head are exposed. One of the functions of the adjustable connector is to ensure the stability of the breathing module 2 when worn. At the same time, air is injected into the fastening airbag 30 through the airbag inlet tube 31 to ensure the fit and comfort between the cover and the exposed area of ​​the wearer's head. Together with the matching plug and adjustable webbing 22, it is easy to match wearers with different head shapes or sizes. The second pressure control valve 110 can effectively control the air intake of the fastening airbag 30. This air intake is the normal air volume for ordinary wearers. If special people (head size is too large or too small) are encountered, the length of the adjustable webbing 22 can be adjusted directly.

[0033] To better meet the diverse needs of the adjustable connector, further limitations are made, namely, the cover includes an upper cover 9 that matches the top of the wearer's head and a back cover 16 that matches the back of the wearer's head; the upper cover 9 and the back cover 16 are connected to each other, and a fastening airbag 30 is provided on the inner sidewall of both the upper cover 9 and the back cover 16, and the airbag inlet pipe 31 has two branches and is connected to the two fastening airbags 30 respectively.

[0034] As a preferred design, the purpose of dividing the cover into sections is to increase the pressure points of the breathing module 2, which can greatly improve the wearer's comfort and form a stable seal between the breathing module 2 and the wearing area. At the same time, the upper cover 9 and the rear cover 16 are made of carbon fiber, which reduces the weight of the entire breathing module 2 while ensuring its damage resistance. The fastening airbags 30 on the upper cover 9 and the rear cover 16 are supplied with air through two branches of the airbag inlet pipe 31, and the two fastening airbags 30 are equipped with exhaust solenoid valves 105 electrically connected to the control module 106, which can realize the depressurization when the wearer removes the breathing module 2.

[0035] When the wearer walks, speaks, or changes facial expressions, a momentary gap occurs between the face and the sealing airbag 8, causing a sudden drop in the internal pressure of the sealing airbag 8. If the pressurized air intake pipe 26 is still filling the cover with air at atmospheric flow at this time, the leakage at the seal will continue to expand, and both blood oxygen and pressure control targets will be lost. To solve the above problems, the control module 106 in this embodiment is configured as follows: when the pressure sensor detects that the internal pressure of the sealing airbag 8 has dropped below a preset first threshold, the control module 106 generates a first control signal to restrict or cut off the flow of the pressurized air intake pipe 26, and at the same time, prioritizes the output flow of the booster pump 103 to the sealing air intake pipe 29 to restore the pressure of the sealing airbag 8 to the target value within a preset time. After the pressure sensor reports that the pressure of the sealing airbag 8 has recovered to the target value, the control module 106 generates a second control signal to release the flow restriction on the pressurized air intake pipe 26 and restore the normal air supply distribution of each pipeline.

[0036] Furthermore, once the control module 106 detects that the sealing airbag 8 is showing a tendency to collapse under pressure, it determines that the sealing performance has endangered the system function and promptly concentrates all the limited air source power for emergency reconstruction of the seal. Even if the pressurization inside the hood is suspended for a very short time, the sealing level must be stabilized first.

[0037] To avoid pain or even pressure injury caused by excessive airbag pressure, this embodiment has a first pressure upper limit threshold for the sealing airbag 8 covering the wearer's face and a second pressure upper limit threshold for the sealing airbag 8 covering the ear area. The second pressure upper limit threshold is set lower than the first pressure upper limit threshold. The control module 106 is configured to prioritize ensuring that the internal pressure of the sealing airbag 8 in the ear area does not exceed the second pressure upper limit threshold when adjusting the output pressure of the sealing air inlet pipe 29. By configuring a lower safety pressure threshold separately for the ear area in the control module 106, even if the sealing air inlet pipe 29 supplies air to both the face and ear airbags simultaneously in the physical pipeline, the software can still limit the actual pressure in the ear to a level far below the face's tolerance threshold through pressure relief valve linkage or pulse air supply duty cycle adjustment. Under the premise of supplying air through the same air path, differentiated pressure management for different anatomical areas is achieved, making ear physiological data the boundary condition for control decisions.

[0038] In this embodiment, the oxygen generating module 101 and the oxygen storage cylinder 102 are mutually auxiliary or coordinated components. The oxygen storage cylinder 102 is installed inside the storage backpack 1. One output end of the oxygen storage cylinder 102 is connected to the buffer chamber 5 through a first one-way valve 107, and the other output end of the oxygen storage cylinder 102 is connected to the oxygen supply pipe 36 through a solenoid valve 105. The oxygen supply pipe 36 is connected to the inside of the sealed cavity 32. To increase the flexibility of use, the oxygen storage cylinder 102 is installed in the storage backpack 1, and the oxygen storage cylinder 102 has two output ends (i.e., output ends), and the first one-way valve 107 and the solenoid valve 105 are respectively installed on the two output ends. When the oxygen generating module 101 and the entire system fail, the oxygen storage cylinder 102 can serve as a backup gas source. The adjustable solenoid valve 105 and the oxygen supply pipe 36 ensure the smooth flow of air to the breathing module 2. When the power of the oxygen generating module 101 decreases and the air flow in the buffer chamber 5 is insufficient to support the supply of air to the inflatable components such as the sealing airbag 8, the oxygen storage cylinder 102 can inject new air into the buffer chamber 5 through the first one-way valve 107, and at the same time provide a pressurized air source for the sealing airbag.

[0039] In particular, when the inhalation volume exceeds the maximum output threshold of the booster pump 103 and the oxygen generation module 101 during strenuous exercise, the oxygen cylinder can also provide gas source compensation to the buffer chamber 5, enabling the device to flexibly switch between pressurization and oxygen supply modes in different usage scenarios, and to continuously pressurize and supply gas. Preferably, in this embodiment, both output ends of the oxygen storage cylinder 102 are equipped with corresponding one-way flow and pressure regulating valves to ensure that the gas source output to the oxygen supply pipe 36 or the buffer chamber 5 can be directly used by the wearer.

[0040] Preferably, in this embodiment, the sealed cavity 32 is provided with two air inlets 37, which are used to connect with the pressurized air inlet pipe 26 and the oxygen supply pipe 36 respectively, and each of the two air inlets 37 is provided with an air intake valve.

[0041] Preferably, the communication module 4 includes Bluetooth, which enables interconnection with the wearer's mobile terminal; the positioning module 12 enables real-time location locking of the wearer.

[0042] As a preferred option, the exhaust pipe 6, the booster intake pipe 26, the oxygen supply pipe 36, the sealed intake pipe 29, and the matching detection data transmission cable are bundled together through the integrated pipe 3 to simplify the wiring, reduce the exposed area of ​​the pipes, and extend their service life; and an exhaust port 38 connected to the exhaust pipe 6 is provided in the sealed cavity 32, and an exhalation valve is installed in the exhaust port 38 to prevent airflow backflow.

[0043] Example 2 like Figures 1 to 9As shown, this embodiment is the first type of breathing module 2, which achieves separate sealing of the wearer's face and ears, and achieves detachable connection and fixation between the face and ears and the wearer's head through adjustable connectors, and airbag seals 25 are provided on the face and ears.

[0044] Specifically, the sealed cavity 32 includes a mask body and an adjustable connector. Earmuffs 33 are located on both sides of the mask body, and a face window 24 is located on the front of the mask body. The mask body has an outer peripheral edge that matches the wearer's facial contours. Three airbag-type sealing elements 25 are located at the outer peripheral edge and the wearing contact edges of the two earmuffs 33, respectively. The adjustable connector connects the mask body to the two earmuffs 33 and allows adjustment of their relative positions. In this embodiment, the airbag sealing elements 25 at the outer peripheral edge ensure a tight seal between the mask body and the face, while the airbag sealing elements 25 at the two earmuffs 33 ensure airtightness in both ear areas. The adjustable connector allows wearers with different head shapes to adjust the mask body and earmuffs 33 to the optimal fit, reducing uneven sealing caused by individual differences.

[0045] Furthermore, the air intake and depressurization control methods of the three sealing areas are the same as those of the mouth, nose and ear type sealing cavity 32, that is, the same air source is used in combination with the zone control structure. The two sealing airbags 8 in each area are also equipped with slow-release manual depressurization valves 17. The control button is located on the outer wall of the mask body in an easy-to-operate position. Under the premise of ensuring sealing and comfort, the structure is more compact and suitable for typical usage scenarios where the head does not need to be fully covered.

[0046] Example 3 like Figure 10 As shown, this embodiment is the second type of breathing module 2, which achieves separate sealing of the wearer's mouth and nose and both ears, and achieves detachable connection and fixation between the mouth and nose and both ears and the wearer's head through adjustable connectors, and airbag seals 25 are provided in both the mouth and nose and both ears.

[0047] Specifically, the sealed cavity 32 includes a nose and mouth mask 19, an adjustable connector, and two earmuffs 33. The nose and mouth mask 19 covers the wearer's mouth and nose; the two earmuffs 33 cover the wearer's ears respectively; the adjustable connector connects the nose and mouth mask 19 to the two earmuffs 33 and can adjust the relative positions of the three components; wherein, there are three airbag-type sealing elements 25, which are respectively located at the wearing contact edges of the nose and mouth mask 19 and the wearing contact edges of the two earmuffs 33. In this embodiment, the airbag-type sealing elements 25 for the ears and nose and mouth are provided with the same air inlet pipe, and the air intake is regulated by an air intake control valve to achieve zoned sealing; The sealed air intake pipe 29 is divided into three bypasses, each corresponding to one of the three sealed zones. Each bypass is further subdivided into two branches, and the air intake of the two sealed airbags 8 is controlled by the first air intake control valve 203 and the second air intake control valve 204 at the end of the two branches, respectively. Similarly, the two sealed airbags 8 are equipped with manual pressure relief valves 17, and the pressure relief button for controlling the manual pressure relief valves 17 is embedded in the outer surface of the sealed cavity 32, so that the wearer can manually press it in real time to remove the breathing module 2. Specifically, a slow-release first pressure relief valve 207 is set on the first sealed airbag 201 located in the same sealed zone, and a slow-release second pressure relief valve 208 is set on the second sealed airbag 202. Two manual pressure relief valve buttons 34 are set on the outer wall of the sealed cavity 32, which are used to control the exhaust treatment of the first pressure relief valve 207 and the second pressure relief valve 208, respectively.

[0048] Example 4 like Figure 11 As shown, this embodiment is the third type of breathing module 2, which fully covers the wearer's head. The airbag seal 25 is located at the neck opening, and the airbag seal 25 also adopts a double-layer seal. Under the premise of isolating the breathing module 2 from the outside world, the fully covered breathing module 2 can effectively prevent the wearer's head from falling and impacting.

[0049] Specifically, the sealed cavity 32 includes a shell 35, which is used to wrap around the wearer's entire head and has a neck opening. The shell 35 also has a face window 24. The airbag-type seal 25 is located at the neck opening to form an airtight seal around the wearer's neck during wear. In this embodiment, the face window 24 on the shell 35 ensures the wearer's normal field of vision, and the airbag seal 25 is located at the neck opening. The two sealing airbags 8 in the airbag seal 25 have a real-time pressure detection function, and effectively coordinate with the air intake volume of the pressurized air intake pipe 26, the pressure inside the shell 35, and the oxygen concentration inside the shell 35. This ensures both the wearer's neck comfort and effective isolation between the inside of the shell 35 and the outside environment. It is particularly important to note that when one or both of the sealing airbags 8 rupture, resulting in insufficient sealing pressure, the control module 106 will intervene in a timely manner, controlling the booster pump 103, oxygen generation module 101, and first pressure control valve 109 to supplement the air intake of the booster intake pipe 26 in real time. At the same time, corresponding communication and warning devices can be set on the outer wall of the housing 35 to simultaneously send the wearer's status to the control terminal in the background, enabling the timely formulation of emergency response measures and effective warning to the wearer.

[0050] Example 5 In this embodiment, the solar panel supplements the power module 104 with electricity, and can be flexibly selected according to the usage scenario to improve the device's endurance in outdoor, high-altitude, and other environments without external power sources. Specifically, the solar panel receives solar energy and converts it into electrical energy stored in the lithium battery; it can also be equipped with a Bluetooth 5.2 module and a WiFi module to achieve communication; the breathing module 2 is equipped with a communication module 4, which enables the device to connect with mobile phones and communicate with other devices, realizing device positioning, remote data transmission, monitoring, and emergency handling.

[0051] In this embodiment, the outer shell of the storage backpack 1 is made of lightweight and pressure-resistant material, the power module 104 is a lithium polymer battery with an energy density of 450-500Wh / kg, a weight of ≤500g, supports fast charging and has a battery life of ≥4 hours; the oxygen generation module 101 adopts molecular sieve oxygen generation technology, with an oxygen concentration of 50-93%±3% and an oxygen production rate adjustable in the range of 1-4L / min; the ultra-lightweight carbon fiber gas cylinder has a capacity of ≥1L, a working pressure of 15MPa, and a battery life of ≥4 hours in a mixed mode of oxygen storage and pressurized gas at a concentration of 30-50%.
