Description

Technical Field

[0001] The invention belongs to the field of fire-fighting equipment, in particular to a portable self-oxygen-supplying long-acting fire-fighting breathing device. Background Art

[0002] When a fire occurs or dangerous goods leak, it is our firefighters who have to complete such emergency rescue missions. In this process, the rescue workers' physical strength is often greatly consumed. For example, when a fire occurs in a high-rise building, firefighters need to carry a compressed air breathing device weighing nearly 20 kilograms and go up and down the stairs many times. However, due to the heavy weight of existing compressed air breathing devices, when firefighters walk to more than ten or even twenty floors, they often become physically exhausted, which not only reduces the rescue capability, but also greatly affects the safety of firefighters. At the same time, the oxygen generators in existing compressed air breathing devices are all in powder form and are placed directly in the breathing device. After a short period of use, the water vapor in the user's breath causes the surface to become gelatinized, which greatly reduces the oxygen production effect of the oxygen generator, further affecting the safety of firefighters. Summary of the invention

[0003] In view of the defects of the existing compressed air breathing apparatus, the technical problem to be solved by the present invention is to provide a portable self-oxygen-supplying long-acting fire-fighting breathing apparatus which is light in weight, has good oxygen production effect and long-term continuous oxygen production.

[0004] In order to achieve the above object, according to one aspect of the present invention, the present invention is implemented by the following technical measures: a portable self-oxygen long-acting fire-fighting breathing apparatus, comprising:

[0005] A shell, wherein the top of the shell is open and the inside is hollow to form a storage cavity;

[0006] An oxygen production module, wherein the oxygen production module is stuck at the opening of the shell, and the interior of the oxygen production module is hollow, a granular oxygen producing agent is arranged in the oxygen production module, and air outlets are arranged on the upper and lower end surfaces of the oxygen production module, and an elastic air bag connected to the interior of the oxygen production module is also arranged on the lower end surface of the oxygen production module;

[0007] A cover, the cover is used to seal the open side of the housing, and the cover is provided with a hollow connecting column for connecting a breathing hose or a mask;

[0008] The shell and the cover are both made of waterproof and fireproof materials.

[0009] The portable self-oxygen-supply long-acting fire-fighting breathing device has a hollow shell and only has an oxygen-producing module installed inside, so the overall weight is very light, which is convenient for firefighters to carry and greatly saves physical strength. At the same time, the granular oxygen-producing agent not only forms a gap space inside, but also is not easy to gelatinize. Under the condition of the same weight of oxygen-producing agent, the rescue time can be increased tenfold. The shell and the cover are made of waterproof and fireproof materials, which can also effectively protect and increase the service life. Together with the professional fire-fighting mask and hose, the service life can be effectively guaranteed. At the same time, the elastic airbag isolates the internal air from the outside to prevent the inhalation of toxic and harmful gases.

[0010] Furthermore, the oxygen production module is provided with an oxygen production module tray outside, the top of the oxygen production module tray is open and the inside is hollow for placing the oxygen production module, the bottom of the oxygen production module tray is fixed with an elastic airbag, the two ends of the oxygen production module tray are provided with clamps, the clamps are used to abut against the upper end of the shell, the bottom of the oxygen production module is provided with feet, the two sides of the oxygen production module and the oxygen production module tray have gaps, and the cover is tightly and movably fixed to the shell. The above design facilitates the circulation of air and can improve the oxygen production effect. At the same time, as long as more small oxygen production module trays are carried, they can be quickly replaced during rescue, thereby improving the survival rate of rescue.

[0011] Furthermore, the air outlet at the upper end of the oxygen production module is the exhaled gas inlet, and the air outlet at the lower end of the oxygen production module is the oxygen outlet. The exhaled gas inlet and the oxygen outlet are both in two rows or two, and the oxygen outlet is closer to the center of the oxygen production module than the exhaled gas inlet. The hollow connecting column of the cover is located in the center of the oxygen production module. The above is to further improve the oxygen production effect. When the user exhales inward, the gas will impact on the surface of the oxygen production module between the two exhaled gas inlets and disperse, which is convenient for fan-shaped diffusion and enters the oxygen production module through the exhaled gas inlet to contact the granular oxygen generator.

[0012] Furthermore, an exhaust hole is provided on the lower end surface of the shell. The above design is to cool the oxygen generator quickly without adding ice cubes for cooling. The structure achieves the function of a "bellows". Through the exhaust hole at the bottom of the shell, the air in the shell is always in convection and cooling with the outside air, effectively reducing the heat generated by the reaction of the oxygen generator in the airbag, and maintaining the temperature at a level close to human body temperature, so that the human body will not feel uncomfortable due to the increase in gas temperature during breathing.

[0013] Furthermore, a filter element is provided in the hollow connecting column.

[0014] Compared with the prior art, the advantages of the present invention are: light overall weight, good oxygen production effect, good oxygen production sustainability, which can not only well ensure the user's physical strength, but also improve the rescue time, rescue success rate and rescue safety.

[0020] Example 1

[0021] Please refer to Figure 1A portable self-oxygen-supply long-acting fire-fighting breathing device provided in this embodiment includes an outer shell 1, an oxygen-producing module 2, an elastic airbag 3, a cover 6 and an oxygen-producing module tray 8. The outer shell 1 is preferably a quadrilateral with an open top and a hollow interior to form a storage cavity. The oxygen-producing module tray 8 and the oxygen-producing module 2 are also preferably quadrilaterals. The oxygen-producing module tray 8 is also open at the top and hollow inside. Horizontal clamps 9 extend outward on both sides of the upper end of the oxygen-producing module tray 8. The oxygen-producing module tray 8 is slightly smaller than the inner diameter of the outer shell 1. When the oxygen-producing module tray 8 is placed in the outer shell 1, the clamps 9 on both sides just abut against the upper ends of both sides of the outer shell 1. The oxygen-producing module 2 is hollow inside. A granular oxygen-producing agent is placed in the oxygen-producing module 2. The oxygen-producing agent is potassium superoxide. The upper end surface of the oxygen-producing module 2 is provided with two or two rows of exhaled air outlets. The oxygen production module 2 has an inlet 4, and the lower end surface of the oxygen production module 2 has two or two rows of oxygen output ports 5. At the same time, the oxygen output port 5 is closer to the center of the oxygen production module 2 than the exhaled gas inlet 4. The above-mentioned oxygen production module 2 is slightly smaller than the oxygen production module tray 8, so that there is a gap after it is placed in the oxygen production module tray 8. In order to ensure the gap at the lower end of the oxygen production module 2, the lower ends of the above-mentioned oxygen production module 2 are also fixed with feet 10 on both sides. The above-mentioned cover 6 is tightly and movably sleeved on the upper end of the shell 1 to close the shell 1. A hollow connecting column 7 is fixed at the center of the shell 1 and the center of the oxygen production module tray 8. The hollow connecting column 7 on the above-mentioned shell 1 is used for connecting a breathing hose or a mask. At the same time, a filter element is arranged in the hollow connecting column 7. The hollow connecting column 7 on the above-mentioned oxygen production module tray 8 is used for fixing the elastic airbag 3.

[0022] When in use, the user wears a mask, and when exhaling, the gas filter element directly impacts the oxygen producing module 2 and disperses, and the dispersed gas passes through the exhaled gas inlet 4 to the oxygen producing module 2 to more evenly contact with the oxygen producing agent to produce oxygen, and the produced oxygen passes through the oxygen output port 5 to the elastic airbag 3. When inhaling, the oxygen in the elastic airbag 3 will pass through the oxygen producing module tray 8 and the oxygen producing module 2 and be discharged from the filter element for people to breathe. In this process, oxygen and carbon dioxide are not connected to the outside, and internal circulation is realized. At the same time, the portable self-oxygen-supplying long-acting fire-fighting breathing device designed in this way has a hollow shell 1, and only the oxygen producing module 2 and the oxygen producing module tray 8 are installed inside, so the overall weight will be very light, which is convenient for firefighters to carry and greatly saves physical strength. At the same time, the granular oxygen producing agent not only forms a gap space inside, but also is not easy to produce gelatinization. Under the condition of the same weight of oxygen producing agent, the rescue time can be increased tenfold.

[0023] In order to facilitate the cooling of the oxygen generating agent, a plurality of exhaust holes 11 are opened on the lower end surface of the shell 1. The shell 1 with such a structure achieves the function of a "bellows". Through the exhaust holes 11 at the bottom of the shell, the air in the shell 1 is always in convection and cooling with the outside air, which effectively reduces the heat generated by the reaction of the oxygen generating agent in the elastic airbag 3, and maintains the temperature at a level close to the human body temperature, so that the human body will not feel discomfort due to the increase in gas temperature during breathing. In addition, the design of such a structure also eliminates the use of ice cubes for cooling, reducing the overall weight.

[0024] To sum up, the portable self-oxygen-supply long-acting fire-fighting breathing device provided in this embodiment has a light overall weight, good oxygen production effect, and good oxygen production sustainability. It can not only well ensure the physical strength of the user, but also improve the rescue time, rescue success rate and rescue safety. At the same time, the portable self-oxygen-supply long-acting fire-fighting breathing device provided in this embodiment can also be used in high-altitude and oxygen-deficient environments, plateau tourism, emergency escape from high-rise disasters, mine emergency assistance, and urban underground pipeline maintenance operations.

[0025] Of course, in the above structure, the outer shell 1 and the cover 6 are made of waterproof and fireproof materials, and of course the materials can be selected according to the use requirements.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
