Description

Technical Field

[0001] This utility model relates to the field of rescue equipment technology, and in particular to a breathing control device for snow rescue. Background Technology

[0002] In extremely cold snow environments, breathing aids play a crucial role in rescue operations, especially in snow rescue scenarios with low oxygen or high humidity, where the user's respiratory support and life safety depend on the stable operation of the oxygen supply device.

[0003] Existing snow rescue breathing control devices deliver oxygen via oxygen cylinders, which are then piped to oxygen masks. The oxygen supply within the masks relies on a single airflow regulation system. Exhaled moisture easily condenses at low temperatures, causing the masks to frost or moisture to flow back into the pipes, affecting oxygen supply efficiency. Furthermore, these devices are mostly powered by traditional batteries, supporting only short-term operation. Some positioning functions depend on external equipment, resulting in poor independence and stability, making them unsuitable for complex snow rescue environments.

[0004] In low-temperature environments, snow breathing aids suffer from the problem of moisture freezing in oxygen pipelines and masks, leading to unstable oxygen supply and insufficient equipment reliability. This is usually solved by local heating, but the effect is limited and the energy consumption is high. The positioning function usually relies on independent equipment, which has low integration and increases the complexity of the equipment. Insufficient independent power supply also affects the positioning efficiency and cannot meet the actual needs of complex snow rescue scenarios. Therefore, a snow rescue breathing control device is proposed to solve the above problems. Utility Model Content

[0009] As a further description of the above technical solution: the oxygen cylinder is set inside the circular backpack, and the outer shell of the circular backpack is connected by a zipper. A flexible solar panel is set on the outside of the circular backpack. A battery and a second controller are respectively set on the bottom inside the flexible solar panel. The battery is electrically connected to the flexible solar panel, the micro fan, the flexible heating film, the first controller, the GPS positioning module, the second controller, and the heating wire.

Combined with the heat insulation tube to reduce heat loss, it achieves the technical effect of stable oxygen delivery and normal equipment operation in extreme low temperature environment. Compared with the existing technology, the oxygen delivery is blocked or the equipment freezes and fails due to low temperature environment. This solves the problem of insufficient reliability of oxygen supply system in extreme low temperature environment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3 This utility model provides an embodiment of a snow rescue breathing control device, comprising an oxygen mask 1, an oxygen tube 2, and an oxygen cylinder 4. The device is characterized in that: a flexible heating film 13 is provided on the inner surface of the oxygen mask 1. The flexible heating film 13 heats the interior of the oxygen mask 1 in low-temperature environments, preventing moisture generated by the user's breathing from condensing into ice at low temperatures, thus ensuring the normal use of the oxygen mask 1 and providing a warm, dry breathing environment, improving user comfort and safety. The oxygen mask 1 is internally equipped with a controller 16 and a GPS positioning module 17. The controller 16 is used to individually control key components inside the oxygen mask 1, including the flexible heating film 13, a miniature fan 11, and the GPS positioning module 17, thereby achieving independent adjustment of each function. The GPS positioning module 17 provides real-time... The positioning function transmits the user's location information to the outside, enabling rescuers to quickly locate the trapped person and improve the efficiency and accuracy of snow rescue. The bottom of the oxygen mask 1 is also equipped with a collection shell 14, and the inside of the collection shell 14 is equipped with absorbent cotton 15, which is used to collect excess moisture generated during the user's breathing, thereby preventing moisture accumulation and increasing the humidity inside the oxygen mask 1, which would affect the performance. There are two elastic bands 3 on the back of the oxygen mask 1. The function of the elastic bands 3 is to fix the position of the oxygen mask 1 on the user's head, and the tightness can be adjusted to adapt to different head shapes and sizes, thereby improving the comfort and stability of wearing it. The outside of the oxygen mask 1 is also equipped with an oxygen spray nozzle 12. The function of the oxygen spray nozzle 12 is to quickly release oxygen for the user to inhale directly in an emergency, thereby ensuring the user's oxygen supply safety and improving the rescue effect.

[0027] The outer surface of the oxygen mask 1 is also equipped with two miniature fans 11. The functions of the two miniature fans 11 are air intake and air exhaust, respectively. One miniature fan 11 draws in fresh air from the outside and replenishes the oxygen mask 1, while the other miniature fan 11 exhausts the waste gas exhaled by the user. The cooperation of these two fans optimizes the air circulation inside the oxygen mask 1, avoids moisture accumulation, and improves the user's breathing comfort and the reliability of the device operation.

[0028] The outlet valve 10 has an automatic adjustment function, which can dynamically control the oxygen flow according to the pressure inside the oxygen cylinder 4 and the user's breathing needs, thereby achieving precise oxygen supply, which saves oxygen resources and ensures the user's breathing needs, and is especially suitable for long-term rescue or extreme environments with limited resources.

[0029] The outer side of the circular backpack 5 is equipped with hand straps 6 and two shoulder straps 8. The hand straps 6 are used to make it easy for the user to carry the circular backpack 5 with one hand, while the two shoulder straps 8 are used to carry the circular backpack 5 on the shoulder, thus providing multiple carrying methods to meet the needs of different rescue missions and improve the portability and applicability of the device.

[0030] Reference Figure 4 and Figure 6 The oxygen tube 2 is equipped with quick-release heads 18 at both ends. One quick-release head 18 is threaded to the oxygen injection port 12, and the other quick-release head 18 is threaded to the air outlet valve 10. The function of the quick-release head 18 is to enable quick connection and disconnection of the oxygen tube 2 with the oxygen injection port 12 and the air outlet valve 10, which facilitates the quick assembly and maintenance of the equipment, improves the efficiency of use, and plays an important role, especially in emergency rescue scenarios.

[0031] The oxygen tube 2 is equipped with an oxygen inner tube 22, a heating wire 21, and an insulation tube 23. The heating wire 21 ensures that the oxygen in the oxygen tube 2 will not freeze due to low temperature, and the insulation tube 23 reduces heat loss to improve the oxygen delivery performance in low temperature environments, thereby ensuring the smooth delivery of oxygen and the reliable operation of the equipment in extreme low temperature environments.

[0032] Reference Figure 5 Oxygen cylinder 4 is installed inside a circular backpack 5, and the outer shell of the circular backpack 5 is connected by a zipper 9. The zipper 9 facilitates the opening and closing of the backpack, making it easier to install, remove, and replace oxygen cylinder 4. A flexible solar panel 7 is installed on the outside of the circular backpack 5. The flexible solar panel 7 uses sunlight to provide additional power to the equipment, especially in environments with good sunlight in snowy areas. A battery 19 and a controller 20 are respectively installed on the bottom inside the flexible solar panel 7. The battery 19 is electrically connected to the flexible solar panel 7, the micro fan 11, the flexible heating film 13, the controller 16, the GPS positioning module 17, the controller 20, and the heating wire 21. The controller 20 is used to intelligently manage the charging and discharging status of the battery 19, improve the efficiency of power utilization, and thus ensure the reliable operation of the device during rescue operations.

[0033] Working principle: During use, oxygen cylinder 4 outputs oxygen through outlet valve 10. Outlet valve 10 dynamically adjusts the oxygen flow rate according to the internal pressure of oxygen cylinder 4 and the user's breathing needs. The oxygen is delivered to oxygen mask 1 through oxygen tube 2. The inside of oxygen tube 2 is heated by heating wire 21 to prevent oxygen from freezing in low temperature environment, and heat loss is reduced by heat insulation tube 23 to ensure smooth delivery of oxygen in extreme low temperature environment.

[0034] Inside the oxygen mask 1, the flexible heating film 13 heats the inside of the mask to prevent water vapor generated by breathing from freezing at low temperatures, while keeping the inside of the mask warm and dry. The collecting shell 14 and the absorbent cotton 15 work together to collect and absorb the moisture generated during breathing, preventing moisture from flowing back to the oxygen tube 2 or condensing inside the mask.

[0035] The micro fan 11 installed on the outside of the oxygen mask 1 is regulated by the controller 16. One micro fan 11 is responsible for drawing in fresh air, and the other micro fan 11 is used to expel the exhaust gas in the mask, thereby optimizing gas circulation, reducing moisture accumulation, and further improving the user's breathing experience. The oxygen spray port 12 can quickly release oxygen in an emergency for the user to inhale directly to improve oxygen supply efficiency and safety.

[0036] The controller 16 independently controls the flexible heating film 13, the miniature fan 11, and the GPS positioning module 17. The GPS positioning module 17 transmits the user's location information in real time via wireless signals, which facilitates rescuers to quickly locate and take action. The external flexible solar panel 7 of the circular backpack 5 charges the battery 19 under sunlight. The battery 19 supplies power to the heating wire 21, the flexible heating film 13, the miniature fan 11, the GPS positioning module 17, etc., through electrical connection, thereby ensuring that the device can operate continuously for a long time in a low-temperature environment.

[0037] In addition, the outer side of the circular backpack 5 is equipped with hand straps 6 and shoulder straps 8, which makes it easy for rescuers to carry and use the device, improving portability and efficiency during the rescue process.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
