[0002] In the field of firefighting, fire-fighting protective clothing is an essential personal protective equipment for firefighters when performing fire-fighting and rescue tasks, which needs to have good fireproof, heat-insulating, wear-resistant, and breathable properties at the same time to protect firefighters from harm in high-temperature, dangerous, and complex fire environment. With the continuous expansion of fire-fighting scenes, firefighters not only have to face the threat of high temperature in fire scenes, but also have to cope with the challenges of cold environment when performing fire-fighting and rescue in cold regions or low-temperature seasons, which puts higher requirements on the cold resistance of fire-fighting protective clothing.
[0003] In order to enhance the heat preservation effect, some protective clothing tries to use some new warm-keeping technology or material, but these measures often have adverse effects on the original fireproof performance of the protective clothing, making it difficult to achieve cold resistance while ensuring good fireproof performance. For example, some electric heating type warm-keeping designs may have safety hazards in high-temperature environment due to wiring problems, or some heavy warm-keeping materials may affect the overall lightness and flexibility of the protective clothing, thereby interfering with the normal action of firefighters in the fire scene and reducing the efficiency of fire-fighting and rescue.

[0026] Referring to the accompanying Figs. 1-3 The utility model provides a fire service cold resistance fire extinguishing clothes, the fire service cold resistance fire extinguishing clothes provided by the utility model, including the protective clothing body 1000, the protective clothing body 1000 is provided with cold protection layer 100, breathable layer 200, heat insulation layer 300 and flame -retardant layer 400 in proper order from inside to outside,
[0027] Cold protection layer 100 includes a plurality of parallel arrangement and intercommunication heat insulation cavities 110, and the one end of heat insulation cavity 110 is provided with the air hole 111 communicated with the outside of protective clothing body 1000, and the air hole 111 is detachably connected with one-way air valve 120, and the one-way air valve 120 only allows gas to enter heat insulation cavity 110 inside from the outside of protective clothing body 1000 via air hole 111,
[0028] The protective clothing body 1000 is provided with pocket member 500, and the air hole 111 is located on the inner side of the pocket member 500, and the pocket member 500 can be elastically active in opening and closing.
[0029] Based on the above technical features, the temperature insulation cavity 110 in the cold protection layer 100 uses air as a heat insulation medium, effectively blocks the loss of human body heat to the outside, and builds a good warm barrier. The one-way valve strictly controls the gas flow direction, and the air pressure deflation treatment of the temperature insulation cavity 110 is realized by disassembling the one-way valve; the pocket component 500 realizes the introduction of air flow from the air port 111 to the one-way valve through the elastic activity of opening and closing, providing a convenient adjustment means for firefighters. According to the actual cold degree and personal body feeling needs, the state of the pocket component 500 can be simply controlled by opening and loosening operation, so that the air quantity in the temperature insulation cavity 110 can be flexibly adjusted, and the warm-keeping effect can be enhanced or maintained as needed, effectively meeting the warm-keeping requirements in different environments, greatly improving the applicability of the fire suit; not only avoids the leakage of warm air in the temperature insulation cavity 110, but also in the process of inflating by opening the pocket component 500, introduces the outside cold air and makes it warm in the temperature insulation cavity 110 by the human body heat, which significantly improves the warm-keeping effect; The cold protection layer 100, the air permeable layer 200, the heat insulation layer 300 and the flame retardant layer 400 are arranged in the protective clothing body 1000 from inside to outside, which not only ensures the warm-keeping effect, but also has good air permeability, heat insulation and flame retardant performance, which can effectively protect firefighters from high temperature, flame and hot gas in the fire scene.
[0030] It should be noted that the cold protection layer 100 uses inflatable film materials, rubber or silicone elastic inflatable inner container, and other material combinations that can achieve inflatable effect, the air permeable layer 200 selects polytetrafluoroethylene microporous membrane composite fabric and other common air permeable fabrics, the heat insulation layer 300 uses ceramic fiber, rock wool and other conventional heat insulation materials, and the flame retardant layer 400 is made of aramid, flame-retardant polyester fiber and other general high-performance flame-retardant fabrics, which are not limited in detail, and each layer cooperates to protect firefighters comprehensively.
[0031] Further, the inlet end of the one-way valve of the embodiment presents a gradually expanding trumpet-shaped opening, which can effectively increase the contact area of the inlet air. When the external air is under the action of a certain air pressure difference (such as the internal and external air pressure difference generated when the firefighter opens the pocket component 500), the air can flow into the one-way valve inlet in a large area, be easily gathered and guided into the one-way valve, and then smoothly enter the temperature insulation cavity 110, further improving the efficiency of the inlet air.
[0032] Among them, the outer surface of the temperature insulation cavity 110 is provided in a corrugated structure, which can significantly increase the contact area of the temperature insulation cavity 110 with the external environment, optimize the heat exchange process, and further enhance the warm-keeping effect.
[0033] Further, the inner side of the temperature insulation cavity 110 is staggered with a plurality of limiting strips 112, which can be made of fiber material. These limiting strips 112 can effectively regulate the flow and distribution of air in the temperature insulation cavity 110, and divide the originally freely flowing and easily convection gas into relatively small and relatively stable areas, effectively reducing the rapid heat loss caused by gas convection. By limiting the disordered flow of gas, heat can be more stably retained on the side close to the human body, further enhancing the warming effect of the temperature insulation cavity 110.
