Description

Technical Field

[0001] This invention belongs to the field of emergency rescue equipment technology and relates to a positioning escape emergency breathing device, which is used to provide breathing gas to users in oxygen-deficient situations such as emergency refuge or mine environments, and can also transmit positioning signals for rescue.

[0002] Background Technology: Currently, in certain situations such as fires, earthquakes, and mining accidents, large amounts of toxic fumes, dust, or harmful gases are often generated at the scene, causing a sharp drop in the oxygen content of the air. Trapped personnel are highly susceptible to unconsciousness or even suffocation due to inhalation of toxic gases or lack of oxygen. Therefore, providing users with a short-term clean breathing air source during escape is one of the key means to ensure life safety. At the same time, in complex building structures or large disaster areas, rescuers find it difficult to quickly determine the exact location of trapped personnel, which seriously affects rescue efficiency and the survival rate of trapped personnel. If the location information of users could be automatically and promptly transmitted to external rescue forces while providing emergency oxygen supply, the probability of rescue would be greatly improved.

[0003] Some portable escape oxygen supply devices are already available on the market, such as small compressed oxygen cylinders paired with breathing masks, which can provide users with oxygen for several minutes to over ten minutes. However, these products have relatively limited functionality, only addressing breathing issues and unable to actively send out distress signals or provide location information. In environments with dense smoke, obstructed visibility, and poor communication, even if an escapee successfully leaves the initial danger zone, they may not be found by rescuers in time due to exhaustion, disorientation, or unconsciousness. To solve the problem of location and distress signaling, existing technologies have integrated positioning modules into escape masks or oxygen cylinders. These solutions typically use electronic switches to control the positioning module's activation and deactivation, such as a separate button on the mask that the user must manually press to trigger positioning and distress signal transmission. This design has significant drawbacks: in extreme emergency and highly panicked escape scenarios such as fires and earthquakes, users are in a state of high psychological and physiological stress, making them prone to errors or forgetting their actions. If a survivor fails to press the distress button due to panic or injury, the entire location-based distress signal function becomes useless, as the device cannot actively send any effective distress signal, missing the best rescue opportunity. More importantly, if the positioning module is kept in standby mode for extended periods to ensure the device is always available, the battery will continuously drain. Escape emergency devices often need to be stored in building corners, cabinets, or fire extinguisher boxes for long periods, possibly for years without being used. The continuous standby power consumption may cause the battery to run out of power when it is truly needed, rendering the device completely ineffective. If the battery is removed or the power is disconnected during storage to avoid standby power consumption, an additional step of connecting the power is added during emergency use, reducing the chance of gaining more time for self-rescue. Furthermore, in terms of the device's structural layout, existing products often simply stack or haphazardly place oxygen cylinders, masks, and electronic components in a backpack or box. This not only makes it easy for parts to become tangled or fall off during emergency access, but also increases the risk of compressing the tubing, corroding electronic contacts, or accidentally damaging the oxygen tubing due to the mixing of electronic components and oxygen supply lines. The lack of reasonable internal space zoning and fixed structure makes it difficult to guarantee the reliability of the device in both long-term storage and emergency use.

[0004] In existing technology, Chinese patent CN203043366U discloses a car self-rescue device with location communication alarm, which consists of a self-rescue device shell, an oxygen cylinder, an oxygen mask, a window breaker, a snap-fit ​​connection device, a partition plate, a location communication alarm, a power supply, a power switch, and wires. The self-rescue device shell is divided into two parts: a self-rescue device shell cover and a self-rescue device shell body. The self-rescue device shell cover is separated from the self-rescue device shell body. The oxygen cylinder, oxygen mask partition plate, location communication alarm, power supply, and wires are located inside the self-rescue device shell body. The oxygen mask is connected to the oxygen cylinder. The location communication alarm is connected to the power supply and power switch via wires. The power switch is fixed to the surface of the self-rescue device shell body. However, the location communication alarm of this device is controlled by a power switch fixed to the surface of the shell body, requiring the user to manually press the switch in an emergency to activate the location and distress call function. In highly panicked escape scenarios such as car drowning or fire, users are very likely to forget or fail to press the switch due to tension, causing the distress call function to fail. Furthermore, the patent does not involve any magnetic or mechanical zero-power standby solution, and there is a risk of battery depletion if the positioning module is left on standby for a long time.

[0005] In the prior art, Chinese patent CN111184954B discloses a portable self-rescue respirator, including a mouth and nose mask, a breathing tube, an oxygen generation module, an air bag, an alarm positioning unit, a shell, and an oxygen-generating agent; the mouth and nose mask, breathing tube, and oxygen generation module are connected in sequence; the oxygen generation module includes an oxygen generation tank and a four-way unit, the oxygen generation tank is connected to the four-way unit, the air bag is connected to the oxygen generation tank, and the oxygen-generating agent is placed inside the oxygen generation tank; the alarm positioning unit is placed on the air bag, and the shell covers the oxygen generation module. However, although this patent mentions the alarm positioning unit, it does not explain in detail how the unit is triggered. It is impossible to determine from the published information whether it has an automatic triggering function, nor is there any evidence that it solves the standby power consumption problem during long-term storage. If it relies on manual triggering, there is also a risk of forgetting or making mistakes during operation. Furthermore, although the alarm positioning unit is placed on the air bag, the internal design of the device lacks a functional partitioning and fixation design similar to that of this invention, which uses an insulating liner. During long-term storage, the mixing of electronic components and the breathing tube may increase the risk of damage. This device uses chemical oxygen-generating agents, but the oxygen supply is not as continuous and controllable as the compressed oxygen cylinder solution, and the oxygen production process may be accompanied by problems such as heat release.

[0006] In existing technology, Chinese patent CN204723624U discloses an IoT-based intelligent escape device, including a base and a mask. The base has a mask slot, and the mask is detachably fixed to the mask slot. The mask has a microprocessor, a filter surface, a directional projection module, and a GPS transmitter module. The directional projection module includes a projection light on the mask, a handheld terminal, and a GPS network. The handheld terminal has a microprocessor, a GPS receiver module, and a display screen. The microprocessor controls the GPS transmitter module to transmit location information through the GPS network. However, this device is only a filter-type smoke mask and does not have an independent emergency oxygen supply. In an environment where the oxygen content drops sharply, filtration alone cannot solve the problem of oxygen deficiency and suffocation. Furthermore, since the mask integrates a microprocessor and a GPS transmitter module, it requires continuous battery power to operate and does not involve any zero-power standby design, posing a risk of battery depletion after long-term storage.

[0007] The aforementioned existing emergency breathing devices and escape breathing devices suffer from problems such as inconvenience in carrying, inability to automatically transmit signals, and high power consumption during standby of the positioning device. Through research and analysis, the inventors have found that no existing technology discloses a positioning and escape emergency breathing device that can achieve zero power consumption during long-term storage, automatically trigger a positioning and distress signal without any additional operation during emergency use, and possesses a reasonable internal structure, convenient access, and reliable fixation. Therefore, inventing a positioning and escape emergency breathing device can overcome the shortcomings of existing technologies. It is convenient to carry, can automatically and synchronously transmit usage signals and location information while wearing an oxygen supply cylinder, and consumes no power during long-term standby, eliminating the need for battery replacements, reducing rescue difficulty and the frequency of routine maintenance, increasing the user's escape success rate, and enhancing safety and practicality. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and to design a positioning escape emergency breathing device that can achieve zero power consumption standby during long-term storage, automatically trigger a positioning distress signal without any additional operation during emergency use, and has a reasonable internal structure, is easy to access, and is fixed and reliable. This solves the problems of existing devices being inconvenient to carry, unable to automatically send signals, and having high power consumption during standby.

[0009] To achieve the above objectives, the present invention provides a positioning escape emergency breathing device, the main structure of which includes a support bag, an oxygen cylinder, an oxygen mask, and a magnetically controlled positioning triggering component. The support bag is an openable and closable zippered soft-pack container, including a lid and a body. A ring-shaped zipper assembly is provided along the outer edge of the lid and the body, and the lid and body are closed by the zipper assembly. The support bag has an insulating liner inside, which divides the body into an oxygen cylinder fixing area, an accessory storage area, and a positioning and installation area. The oxygen cylinder fixing area has at least one horizontal elastic fixing strap for securing the oxygen cylinder body. The accessory storage area has a horizontal storage strap for coiling and fixing the oxygen mask and its attached breathing tube to the inner wall of the body. The positioning and installation area is fixedly equipped with the magnetically controlled positioning triggering component. An arched portable handle is fixedly connected to the top of the body, and an adjustable length handle is fixedly connected to the bottom of the body. The bag strap, especially the long strap, can be adjusted in length via a D-ring buckle and features a snap fastener for securing the bag to the user's back or waist. A magnetic positioning trigger assembly is fixed inside the bag, comprising a main control module, power supply, rocker arm, micro switch, internal magnet, and external magnet. These components are encapsulated in an insulating box, which is fixed within the bag via a positioning mounting area. One end of the rocker arm is fixed with the internal magnet, while the other end abuts against the trigger button of the micro switch. In its natural state, the rocker arm has a tendency to reset, switching the micro switch to the ON state. The micro switch is connected in series in the power supply circuit of the power supply and the main control module, and is of the type with normally closed contacts and a common contact. Its normally closed terminal is connected in series between the power supply output and the main control module's power input. The external magnet is positioned to align with the internal magnet when the bag lid is closed. The external magnet and the internal magnet have opposite polarities to generate an attractive force. When the external magnet is attracted, the rocker arm is pulled and presses the micro switch to disconnect the circuit. When the external magnet is released, the rocker arm returns to its original position and the micro switch closes the circuit. The external magnet is located at the opening of the package.

[0010] The oxygen cylinder fixing area of ​​the present invention has quick-release buckles at both ends of the transverse elastic fixing strap, which can be quickly unbuckled and removed in an emergency; the storage strap of the accessory storage area is an elastic webbing with Velcro, which can be pulled open and the mask can be removed with one hand.

[0011] The outer layer of the carrier bag involved in this invention is made of flame-retardant coated fabric, and the inner lining is made of heat-insulating and cushioning material, so as to protect the internal equipment and oxygen supply cylinders in a certain degree of high temperature or dust environment.

[0012] When the flexible bag is in the closed state, the external magnet attracts the internal magnet through magnetic attraction, causing the rocker arm to overcome its reset tendency and forcing the microswitch to switch to the power-off state. At this time, the power supply circuit between the power supply and the main control module is cut off, and the main control module is in a completely power-off, zero-power standby state. Since there is no standby current consumption, the battery inside the device can be stored for several years. When the flexible bag is in the open state, the bag body separates from the cover, the external magnet separates from the rocker arm as the opening opens, and the rocker arm resets under its own elasticity or gravity, forcing the microswitch to switch to the conduction state. The main control module then powers on and starts, acquires positioning data, and sends positioning signals outward.

[0013] In an emergency, the positioning escape emergency breathing device of this invention allows the user to quickly unzip the bag and open the flap. As the flap opens, the external magnet fixed to it moves away from the bag body, separating from the internal magnet, and the magnetic attraction disappears. Under the pushing force of the elastic reset component, the rocker arm slides back towards the microswitch along the guide structure, and its end presses against the trigger button of the microswitch again, forcing the normally closed contact of the microswitch to close again. The power supply circuit is connected, and the main control module immediately powers on and starts. The microcontroller built into the main control module executes an initialization program after power-on, automatically acquiring the location coordinate data collected by the built-in GNSS positioning module. This location information, along with the pre-stored device identification code, is sent via the built-in mobile communication module in the form of data packets or SMS messages to a preset emergency monitoring platform or designated mobile terminal, completing an automatic distress call. Simultaneously, the main control module can also illuminate a high-brightness LED indicator or drive a buzzer to emit intermittent alert sounds to assist rescuers in locating the device.

[0014] This invention also relates to a method of using a positioning escape emergency breathing device:

[0015] S1: Secure the carrying bag to the user's back or waist with a long strap and buckle, or carry it to the usage location with an arched portable handle;

[0016] S2: Pull open the ring zipper assembly to separate the bag cover from the bag body. The external magnet inside the bag cover will then separate from the internal magnet inside the bag body. The magnetic attraction will disappear, and the trigger button of the micro switch will pop outward by its own internal reset force, pushing the rocker arm and internal magnet to reset. The normally closed contact of the micro switch will close, the power supply circuit will be connected, the main control module will automatically power on and start, and send out a distress signal containing location data.

[0017] S3: Untie the horizontal storage straps in the accessory storage area, take out the oxygen mask and its connected breathing tube, and connect the breathing tube to the outlet of the oxygen supply cylinder.

[0018] S4: Put the oxygen mask on the user's face, making sure it fits snugly against the face, open the valve of the oxygen cylinder, and start emergency breathing.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] (1) Achieving a perfect combination of true zero-power standby and instant automatic triggering, the power supply circuit is switched on and off using the action of opening and closing the bag cover when retrieving escape equipment through a cleverly designed magnetic positioning trigger component. During storage, when the bag cover is closed, the external magnet attracts the internal magnet and drives the rocker arm to press the micro switch, the power supply circuit is physically cut off, the main control module is in a completely de-energized state, there is no standby current consumption, and the battery energy can be fully preserved for several years, fundamentally solving the problem of traditional electronic emergency equipment failing due to battery depletion caused by long-term standby. In the instant of emergency use and opening the bag cover to retrieve the oxygen mask, the magnetic attraction disappears as the bag cover separates, and the power supply circuit is automatically connected. No additional power-on operation or button triggering action is required from the user, and a distress signal can be sent out immediately. The opening action is both the operation of retrieving the oxygen supply equipment and the triggering action of activating the positioning distress signal. In the highly tense and chaotic escape scenario, the complexity of operation is greatly reduced, and the risk of the distress signal function failing to be activated due to operation omission or error is avoided.

[0021] (2) Its internal space layout is reasonable, convenient to use, and highly reliable. The oxygen supply cylinder, mask, and electronic triggering component are independently fixed in separate areas by an insulating liner. The positions of each component are clear and do not interfere with each other. The oxygen supply cylinder is secured with elastic straps, the mask and air tube are secured by coiled storage straps, and the magnetic positioning triggering component is encapsulated in an independent box and fixed in the positioning installation area. This partitioned design allows the user to quickly and orderly remove and put on the mask in an emergency, without problems such as component entanglement, tubing knots, or electronic components falling off, thus buying valuable time for escape.

[0022] (3) The trigger structure used is ingeniously designed, reliable in operation, and easy to maintain. The magnetic positioning trigger component is encapsulated in a transparent insulating box, which not only protects the internal precision electronic components and mechanical structure from external dust, moisture, and accidental impacts, but also allows quality inspectors and users to directly observe the engagement status of the rocker arm and the micro switch without disassembling the box, facilitating factory inspection and periodic patrols to confirm that the device is in normal standby condition. The micro switch adopts a self-resetting normally closed type, using its internal reset force as the power for rocker arm reset. The structure is extremely simple and compact, reducing the setting of additional elastic elements, reducing the number of parts and potential failure points.

[0023] (4) It possesses excellent environmental adaptability and scalability. The outer layer of the carrier bag is made of flame-retardant coated fabric, and the inner lining is made of heat-insulating and cushioning material, which can protect the internal equipment and gas cylinders to a certain extent in the high temperature and smoke environment of a fire. The main control module supports cyclic transmission of positioning and retransmission of interrupted data to ensure accurate delivery of location information. The overall design takes into account both the static reliability of long-term storage and the dynamic efficiency of emergency use, and can be widely used in emergency escape configurations in high-rise buildings, underground spaces, transportation vehicles, mine operations and other places.

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1:

[0031] This embodiment relates to a positioning escape emergency breathing device, the main structure of which includes a carrier bag 1, an oxygen cylinder 2, an oxygen mask 3, and a magnetically controlled positioning triggering component 4. The carrier bag 1 is a flexible, zippered soft-pack container made of flexible material, including a cover 7 and a body 8. A ring-shaped zipper assembly is provided along the outer edge of the cover 7 and the body 8, and the cover 7 and the body 8 are closed by the zipper assembly. The carrier bag 1 has an insulating liner inside, which divides the body 8 into an oxygen cylinder 2 fixing area, an accessory storage area, and a positioning and installation area. The oxygen cylinder 2 fixing area has at least one horizontal elastic fixing strap for tightening the body of the oxygen cylinder 2. The accessory storage area has a horizontal storage strap for coiling and fixing the oxygen mask 3 and its attached breathing tube to the inner wall of the body 8. The positioning and installation area is fixedly provided with the magnetically controlled positioning triggering component 4. An arched portable handle 5 is fixedly connected to the top of the body 8, and an adjustable long strap 6 is fixedly connected to the bottom of the body 8. The long strap 6 can be adjusted by a D-ring buckle. The length is provided with a buckle so that the user can fix the bag body 8 to the back or waist; the magnetic positioning trigger assembly 4 is fixed inside the bag body 8, including the main control module 9, power supply 10, rocker arm 11, micro switch 12, internal magnet 13 and external magnet 14. The main control module 9, power supply 10, rocker arm 11, micro switch 12 and internal magnet 13 are encapsulated in a transparent insulating box, which is fixed inside the bag body 8 through the positioning installation area; one end of the rocker arm 11 is fixed with the internal magnet 13, and the other end abuts against the trigger button of the micro switch 12. In its natural state, the rocker arm 11 has a reset tendency to switch the micro switch 12 to the conducting state. The micro switch 12 is connected in series in the power supply circuit of the power supply 10 and the main control module 9. It is selected to have a type with normally closed contacts and common contacts. Its normally closed terminal is connected in series between the output terminal of the power supply 10 and the power supply input terminal of the main control module 9. The installation position of the external magnet 14 corresponds to the position that coincides with the internal magnet 13 when the bag cover 7 is closed. The external magnet 14 and the internal magnet 13 have opposite polarities to generate an attractive force. When the external magnet 14 is attracted, the rocker arm 11 is pulled and presses the micro switch 12 to disconnect the circuit. When the external magnet 14 is released, the rocker arm 11 returns to its original position, and the micro switch 12 closes the circuit. The external magnet 14 is located at the opening of the flexible casing 8. The pressing state of the micro switch 12 and the rocker arm 11 can be directly observed through the transparent casing, which is convenient for factory quality inspection and user confirmation of the state before use.

[0032] The transverse elastic fixing strap of the oxygen supply cylinder 2 fixing area involved in this embodiment is equipped with quick-release buckles at both ends, so that the oxygen supply cylinder 2 can be quickly unbuckled and taken out in an emergency; the storage strap of the accessory storage area is an elastic webbing with Velcro, which can be pulled open and the mask can be taken out with one hand.

[0033] The outer material of the carrier bag 1 involved in this embodiment is a flame-retardant coated fabric, and the inner lining is a heat-insulating and cushioning material, so as to protect the safety of the internal equipment and oxygen supply cylinder 2 in a certain high temperature or dust environment.

[0034] In this embodiment, when the carrying bag 1 is in the closed state, the external magnet 14 attracts the internal magnet 13 through magnetic attraction, causing the rocker arm 11 to overcome its reset tendency and forcing the micro switch 12 to switch to the power-off state. At this time, the power supply circuit between the power supply 10 and the main control module 9 is cut off, and the main control module 9 is in a completely power-off, zero-power standby state. Since there is no standby current consumption, the battery in the device can be stored for several years. When the flexible bag is in the open state, the bag body 8 separates from the bag cover 7, and the external magnet 14 separates from the rocker arm 11 as the opening opens. The rocker arm 11 resets under its own elasticity or gravity, forcing the micro switch 12 to switch to the conduction state. The main control module 9 then powers on and starts, acquires positioning data, and sends positioning signals outward.

[0035] In this embodiment, the positioning escape emergency breathing device, when encountering an emergency such as a fire, allows the user to quickly pull open the ring zipper and open the cover 7. As the cover 7 opens, the external magnet 14 fixed thereon moves away from the body 8 and separates from the internal magnet 13, instantly eliminating the magnetic attraction. Under the pushing force of the elastic reset component, the rocker arm 11 slides back towards the micro switch 12 along the guide structure, its end pressing against the trigger button of the micro switch 12, forcing the normally closed contact of the micro switch 12 to close again. The power supply circuit is connected, and the main control module 9 immediately powers on and starts. The microcontroller built into the main control module 9 executes an initialization program after power-on, automatically acquiring the location coordinate data collected by the built-in GNSS positioning module. This location information, along with the pre-stored device identification code, is sent via the built-in mobile communication module in the form of data packets or SMS messages to a preset emergency monitoring platform or designated mobile terminal, completing an automatic distress call. Simultaneously, the main control module 9 can also illuminate a high-brightness LED indicator or drive a buzzer to emit intermittent alert sounds to assist rescuers in locating the device.

[0036] The positioning escape emergency breathing device involved in this embodiment allows the user to quickly untie the storage straps in the accessory storage area, take out the oxygen mask 3, connect the breathing tube to the outlet of the oxygen supply cylinder 2, and open the valve of the oxygen supply cylinder 2 for emergency breathing when the cover 7 is opened to trigger positioning. When in use, the oxygen cylinder can still be placed in the carrying bag 1, and the carrying bag 1 can be carried on the body by the bag strap 6 without affecting movement.

[0037] The oxygen supply cylinder 2 involved in this embodiment is a small, portable compressed oxygen tank, with anti-slip textures on the surface of the cylinder to cooperate with the horizontal elastic fixing strap. A silica gel desiccant pack can be added inside the transparent insulating box to maintain the insulation reliability of the internal components during long-term storage. As an optional enhancement, an auxiliary elastic reset component, such as a compression spring or sheet, can be added between the rocker arm 11 and the inner wall of the box to work in conjunction with the internal reset force of the microswitch 12. The power supply 10 uses a high-capacity, low-self-discharge lithium thionyl chloride battery to ensure long-term energy reserves. The main control module 9 can be set to send a cyclic positioning mechanism, sending an updated position every certain period after power-on until manual intervention to shut down or the battery is depleted.

[0038] In this embodiment, after power-on, the microcontroller of the main control module 9 first delays and waits for the positioning module to complete satellite search and positioning calculation. After obtaining valid location coordinates, it encapsulates the device identification code, location coordinates, and timestamp into a data packet according to a preset protocol and sends it to the emergency monitoring platform via the mobile communication network. If the first transmission fails, it automatically retryes according to the exponential backoff strategy until the transmission is successful or the maximum number of retries is reached.

[0039] The method of using the positioning escape emergency breathing device involved in this embodiment is as follows:

[0040] S1: Secure the carrying bag 1 to the user's back or waist via the long bag strap 6 and buckle, or carry it to the usage position via the arched portable handle 5;

[0041] S2: Pull open the ring zipper assembly to separate the bag cover 7 from the bag body 8. The external magnet 14 inside the bag cover 7 will then disengage from the internal magnet 13 inside the bag body 8. The magnetic attraction will disappear, and the trigger button of the micro switch 12 will pop outward by its own internal reset force, pushing the rocker arm 11 and the internal magnet 13 to reset. The normally closed contact of the micro switch 12 will close, the power supply circuit will be connected, the main control module 9 will automatically power on and start, and send out a distress signal containing positioning data.

[0042] S3: Untie the horizontal storage straps in the accessory storage area, take out the oxygen mask 3 and its connected breathing tube, and connect the breathing tube to the outlet of the oxygen supply bottle 2.

[0043] S4: Put the oxygen mask 3 on the user's face, making sure it fits snugly against the face, and open the valve of the oxygen cylinder 2 to start emergency breathing.

[0044] Example 2:

[0045] This embodiment involves a comparative test of the standby power consumption and battery life of the magnetic positioning trigger component of the positioning escape emergency breathing device described in Embodiment 1 with other existing technologies. To verify the power consumption advantage of the magnetic positioning trigger component 4 of this device during long-term storage, three typical positioning modules—Zhongke Micro ATGM332D-6N, SIMCom SIM65M-CB, and Quectel L76K—and one NB-IoT communication module were selected, and their power consumption performance in the traditional standby mode and the physical power-off mode of this solution were tested respectively.

[0046] Test conditions: Ambient temperature 25℃±2℃, power supply voltage 3.3V, the average current of each module in standby mode was measured using a Keysight N6705B DC power consumption analyzer.

[0047]

[0048] Based on a standby current of 40 μA and a supply voltage of 3.3V: the daily power consumption of a traditional standby solution is 960 μAh, and the annual power consumption is 350 mAh, while the annual power consumption of this device is 0 μAh. The device is equipped with a single ER34615 lithium thionyl chloride battery with a nominal capacity of 19000 mAh and a rated voltage of 3.6V. Traditional standby solutions suffer from severe negative electrode passivation and premature capacity depletion due to continuous micro-current discharge, typically reducing the actual effective service life to 3 to 5 years. After 3 years, the ability to drive high-current loads decreases significantly, and after 5 years, the communication module often fails to start normally due to voltage lag, rendering the device practically unusable. In contrast, this device achieves a standby life of over 10 years due to zero power consumption.

[0049] The comparative experimental data presented in this embodiment clearly demonstrate that even with low-power devices, traditional standby solutions inevitably consume hundreds of milliampere-hours of battery capacity annually. Combined with the battery's self-discharge effect, this can lead to severe battery depletion or even complete exhaustion after 3 to 5 years of storage. In contrast, the magnetically controlled positioning trigger component in this embodiment achieves zero standby current through magnetic physical power-off. The only way the battery capacity is consumed is through electrochemical self-discharge, and it retains over 90% of its initial capacity even after 10 years of storage. This embodiment fundamentally solves the technical problem of traditional electronic emergency equipment failing due to battery depletion from prolonged standby.

[0050] Example 3:

[0051] This embodiment involves a reliability verification test of the positioning escape emergency breathing device described in Embodiment 1, in accordance with the GB / T 2423 series standards and the IEC 60068-2 series standards, to ensure that the device maintains reliable triggering performance during long-term storage.

[0052] According to GB / T 2423.22 standard, the complete positioning escape emergency breathing device was placed in a high and low temperature test chamber and subjected to temperature cycling tests within the range of -40℃ to +85℃. Each cycle included: heating, high temperature constant temperature, cooling, and low temperature constant temperature, for a total of 10 cycles, with a total duration of not less than 24 hours. After the test, it was left to stand at room temperature for 2 hours, and then the trigger function was tested. After 10 temperature cycles, the magnetic positioning trigger component 4 of all test samples could operate reliably, and the microswitch contacts opened and closed normally without jamming or failure.

[0053] According to GB / T 2423.4 standard, the device was placed in a constant temperature and humidity chamber at 40℃ and 93% relative humidity for 72 hours. After the test, it was removed and allowed to recover under normal temperature and humidity conditions for 2 hours before testing. After the 72-hour damp heat test, there was no visible condensation on the inner wall of the transparent insulating box, and the internal electronic components and mechanical structures showed no rust or corrosion, and the triggering function was normal.

[0054] The ring zipper assembly and magnetic positioning trigger assembly 4 of the carrier bag were subjected to repeated opening and closing tests using an automatic opening and closing test equipment. The opening and closing frequency was 10 times / minute, for a total of 1000 repeated opening and closing cycles. During the test, the trigger function was tested after every 100 opening and closing cycles.

Claims

1. A positioning escape emergency breathing device, characterized in that, The package includes a carrier bag, oxygen cylinder, oxygen mask, and magnetic positioning trigger assembly. The carrier bag is an openable, zippered soft-pack container, comprising a lid and a body. A ring-shaped zipper assembly is provided along the outer edge of both the lid and body, allowing the lid and body to close together. A strap is fixedly connected to the outside of the carrier bag. An internal insulating liner divides the package into an oxygen cylinder securing area, an accessory storage area, and a positioning and mounting area. The oxygen cylinder securing area has at least one horizontal elastic strap to secure the oxygen cylinder. The accessory storage area has a horizontal storage strap to hold the oxygen cylinder in place. The mask and its attached breathing tube are coiled and fixed to the inner wall of the pack. A magnetically controlled positioning trigger assembly is fixedly installed in the positioning and mounting area. The magnetically controlled positioning trigger assembly, fixed inside the pack, includes a main control module, power supply, rocker arm, micro switch, internal magnet, and external magnet. The main control module, power supply, rocker arm, micro switch, and internal magnet are encapsulated in an insulating container, which is fixedly installed inside the pack through the positioning and mounting area. One end of the rocker arm is fixed with an internal magnet, and the other end abuts against the trigger button of the micro switch. In its natural state, the rocker arm has the function of switching the micro switch to the conducting state. In this configuration, a microswitch is connected in series in the power supply circuit between the power supply and the main control module. It is a type with normally closed contacts and a common contact. The normally closed terminal is connected in series between the power supply output and the main control module's power input. The external magnet is positioned so that it coincides with the internal magnet when the bag lid is closed. The external magnet is located at the opening of the bag. In an emergency, the user quickly pulls the ring zipper to open the bag lid. When the lid is opened, the external magnet, fixed to it, moves away from the bag as the lid moves away from the bag, separating from the internal magnet, and the magnetic attraction disappears. Under the pushing force of the elastic reset component... The rocker arm slides back towards the micro switch along the guide structure, and its end presses against the trigger button of the micro switch again, forcing the normally closed contact of the micro switch to close again. The power supply circuit is connected, and the main control module is immediately powered on and started. After power-on, the microcontroller built into the main control module executes the initialization program, automatically obtains the location coordinate data collected by the built-in GNSS positioning module, and sends the location information together with the pre-stored device identification code to the preset emergency monitoring platform or designated mobile terminal in the form of data packets or SMS through the built-in mobile communication module to complete the automatic distress call.

2. The positioning escape emergency breathing device according to claim 1, characterized in that: The transverse elastic fixing straps in the oxygen supply cylinder fixing area are equipped with quick-release buckles at both ends, and the storage straps in the accessory storage area are elastic webbing with Velcro.

3. The positioning escape emergency breathing device according to claim 1, characterized in that: The top of the bag is fixedly connected to an arched portable handle, and the bottom of the bag is fixedly connected to an adjustable long bag strap. The long bag strap can be adjusted in length by a D-ring buckle and is equipped with a snap buckle.

4. The positioning escape emergency breathing device according to claim 1, characterized in that: The outer layer of the carrier is made of flame-retardant coated fabric, and the inner lining is made of heat-insulating and cushioning material.

The external magnet inside the bag cover will then separate from the internal magnet inside the bag body. The magnetic attraction will disappear, and the trigger button of the micro switch will pop outward by its own internal reset force, pushing the rocker arm and internal magnet to reset. The normally closed contact of the micro switch will close, the power supply circuit will be connected, the main control module will automatically power on and start, and send out a distress signal containing location data. S3: Untie the horizontal storage straps in the accessory storage area, take out the oxygen mask and its connected breathing tube, and connect the breathing tube to the outlet of the oxygen supply cylinder. S4: Put the oxygen mask on the user's face, making sure it fits snugly against the face, open the valve of the oxygen cylinder, and start emergency breathing.
