Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting suits, in particular to a fire-fighting suit with a self-fire extinguishing structure. Background Art

[0002] Fire suits are special clothing worn by firefighters when performing firefighting and rescue missions. They are designed to protect firefighters from harm caused by fire, heat, harmful gases and other dangerous factors. The jackets and pants of fire suits are usually made of flame retardant materials with good fire resistance and heat insulation, which can effectively protect firefighters from harm caused by flames and high temperatures.

[0003] For example, the fire-fighting heat-insulating suit with publication number CN215995339U includes a constricting and fixing mechanism, an adjusting and tightening mechanism, a head-mounted protection mechanism and an internal heat-insulating mechanism. The outer walls of the constricting and fixing mechanism are provided with an adjusting and tightening mechanism, the top of the constricting and fixing mechanism is provided with a head-mounted protection mechanism, and the inner walls of the constricting and fixing mechanism are provided with an internal heat-insulating mechanism. The fire-fighting heat-insulating suit has a fixed strap that fits well with the protective outer suit, which can facilitate the mounting of oxygen cylinders on the back and the support of injured teammates on the back in dangerous situations. The adjusting and tightening mechanism makes it more convenient for firefighters to move after putting on the suit, avoiding the inconvenience of movement caused by the fire suit being too large. The convenience of use and wearing is improved through the head-mounted protection mechanism. The internal heat-insulating mechanism penetrates into the absorbent cotton interior through the filter net for storage, and achieves better heat-insulating and flame-retardant effects through cooperation with the glass fiber inside and outside, completing the entire process of putting on and using the fire suit.

[0004] The fire suits described in the aforementioned comparative documents are generally optimized for their wearing or installation methods. Actual operations have verified that the main function of fire suits is to effectively isolate heat sources from firefighters, thereby ensuring their safety. However, in certain situations, if liquids or sticky substances burn, adhesion may occur, causing the fire to continue to spread on the fire suit, thereby posing a potential risk to firefighters. Utility Model Content

[0005] The purpose of the present invention is to provide a fire suit with a self-extinguishing structure to solve the problem in the above-mentioned background technology that when liquid or sticky substances burn, adhesion may occur, causing the fire to continue to spread on the fire suit, thereby posing a potential harm to firefighters.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a fire-fighting suit with a self-extinguishing structure, comprising a jacket, sleeves, and trouser legs, wherein the sleeves are provided with two sleeves and are symmetrically distributed on both sides of the jacket, and the trouser legs are provided with two sleeves and are symmetrically distributed on the bottom of the jacket;

[0007] The outer side of the jacket and sleeves is provided with a fire extinguishing structure, and the fire extinguishing structure is provided with a first air supply ring, and the first air supply ring is provided with two groups, and each group of the first air supply rings consists of three equally spaced ones distributed on the outer side of the trouser legs, and the three first air supply rings are equally spaced ones distributed on the outer side of the trouser legs. Two second air supply rings are fixedly connected to the outer side of the jacket, and the second air supply rings and the first air supply rings are connected to each other through a connecting pipe, and an air guide pipe is fixedly connected to the middle of the top of the second air supply ring, and the bottom of the first air supply ring and the second air supply ring are fixedly connected to a plurality of equally spaced air outlets;

[0008] The rear side of the outer sleeve is provided with an air supply structure for supplying air to the first air supply ring and the second air supply ring.

[0009] Furthermore, the air supply structure is provided with a back plate, and two symmetrically distributed shoulder straps are fixedly connected to the inner side of the back plate, and the two shoulder straps are sleeved on the outer side of the jacket.

[0010] Furthermore, a fixing plate is fixedly connected to the bottom inner side of the back plate, and fixing holes are provided at both ends of the inner side of the fixing plate, and the insides of the two fixing holes are fixedly connected to the two connecting pipes respectively.

[0011] Furthermore, a mounting plate is fixedly connected to the top inner side of the back plate, and two symmetrically distributed mounting holes are provided inside the mounting plate, and a connecting hole is provided in the middle of the inner side of the mounting plate, and the inside of the connecting hole is fixedly connected to the air guide tube.

[0012] Furthermore, a carbon dioxide bottle and an oxygen bottle are fixedly connected to the inside of the two mounting holes respectively, and the bottoms of the carbon dioxide bottle and the oxygen bottle are fixedly connected to the top of the shoulder strap.

[0013] Furthermore, a vaporizer is fixedly connected to the middle of the top of the mounting plate, and an output end of the vaporizer is fixedly connected to a gas pipe, and two gas pipes are provided.

[0014] Furthermore, the two gas pipes are fixedly connected to an independent gas ring and the top of the carbon dioxide bottle respectively, and the air guide pipe is fixedly connected to the output end of the gas pipe. At the same time, the bottom of the independent gas ring is fixedly connected to a plurality of equally distributed gas outlets.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This fire suit with a self-extinguishing structure is equipped with a fire extinguishing mechanism. The connecting pipe guides the carbon dioxide in the second air supply ring into the first air supply ring. Then, the carbon dioxide inside the first and second air supply rings is discharged through multiple air outlets configured at the bottom. The carbon dioxide discharged through the air outlets is evenly distributed on the outside of the jacket and trouser legs, effectively reducing the temperature in these two areas. At the same time, the discharged carbon dioxide forms a uniform film on the outer surface of the jacket and trouser legs, significantly reducing the oxygen concentration in the surrounding environment, thereby achieving the purpose of suppressing flame combustion.

[0017] Furthermore, a gas supply structure is provided to transfer the liquid carbon dioxide inside the carbon dioxide bottle to the inside of the airway through the vaporizer. The liquid carbon dioxide absorbs a large amount of heat during the vaporization process. Therefore, when the carbon dioxide is distributed on the outside of the jacket and trouser legs, it will effectively achieve a cooling effect. However, it should be noted that the emission of carbon dioxide will reduce the oxygen content in the external environment. Therefore, this operation must be carried out in conjunction with the carbon dioxide bottle to ensure the safety of the user.

[0018] Furthermore, the independent gas ring is consistent in structure with the second gas ring and the first gas ring. When the operator is wearing a fire suit, the independent gas ring is located at the neck of the operator. In addition, through an independent gas pipe, the independent gas ring can obtain a continuous gas supply. Even if the device is damaged, thanks to the separately configured gas pipe, the vaporizer can still deliver carbon dioxide to the independent gas ring, thereby ensuring the safety of the operator's life, especially the effective protection of his or her critical organs.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In a further preferred embodiment of the present invention, Figure 1 - Figure 4 As shown, a fire extinguishing structure is provided on the outside of the jacket 1 and the sleeves 2. The fire extinguishing structure is provided with a first air supply ring 4, and the first air supply ring 4 is provided with two groups, and each group of first air supply rings 4 consists of three equally distributed on the outside of the trouser legs 3. At the same time, the three first air supply rings 4 are equally distributed on the outside of the trouser legs 3. Two second air supply rings 5 are fixedly connected to the outside of the jacket 1, and the second air supply rings 5 and the first air supply rings 4 are connected to each other through a connecting pipe 7. An air guide pipe 6 is fixedly connected to the middle of the top of the second air supply ring 5, and a plurality of equally distributed air outlets 8 are fixedly connected to the bottom of the first air supply ring 4 and the second air supply ring 5. An air supply structure for supplying air to the first air supply ring 4 and the second air supply ring 5 is provided on the rear side of the jacket 1.

[0028] Carbon dioxide enters the second gas ring 5 from the air guide pipe 6, and then the second gas ring 5 and the first gas ring 4 are connected through the connection of the connecting pipe 7. During this process, the connecting pipe 7 guides the carbon dioxide in the second gas ring 5 to the first gas ring 4. Then, the carbon dioxide inside the first gas ring 4 and the second gas ring 5 is discharged through multiple gas outlets 8 configured at the bottom. The carbon dioxide discharged through the gas outlets 8 is evenly distributed on the outside of the jacket 1 and the trouser legs 3, effectively reducing the temperature of these two areas. At the same time, the discharged carbon dioxide forms a uniform thin film on the outer surface of the jacket 1 and the trouser legs 3, significantly reducing the oxygen concentration in the surrounding environment, thereby achieving the purpose of suppressing flame combustion.

[0029] In a further preferred embodiment of the present invention, Figure 5 - Figure 6As shown, the air supply structure is provided with a back plate 9, and two symmetrically distributed shoulder straps 10 are fixedly connected to the inner side of the back plate 9, and the two shoulder straps 10 are sleeved on the outer side of the jacket 1, and a fixing plate 11 is fixedly connected to the bottom inside the back plate 9, and fixing holes 12 are provided at both ends of the inner side of the fixing plate 11, and the two fixing holes 12 are respectively fixedly connected to the two connecting pipes 7, and a mounting plate 13 is fixedly connected to the top inside the back plate 9, and two symmetrically distributed mounting holes 14 are provided inside the mounting plate 13, and a connecting hole 15 is provided in the middle of the inner side of the mounting plate 13, and the inside of the connecting hole 15 is fixedly connected to the air guide tube 6, and a carbon dioxide cylinder 16 and an oxygen cylinder 17 are respectively fixedly connected to the inside of the two mounting holes 14, and the bottoms of the carbon dioxide cylinder 16 and the oxygen cylinder 17 are fixedly connected to the top of the shoulder strap 10, a vaporizer 18 is fixedly connected to the middle of the top of the mounting plate 13, and the output end of the vaporizer 18 is fixedly connected to the gas pipe 19, and there are two gas pipes 19;

[0030] The liquid carbon dioxide inside the carbon dioxide bottle 16 is transferred to the inside of the air duct 6 through the vaporizer 18. During this process, the vaporizer 18 will be responsible for vaporizing the liquid carbon dioxide and passing it into the air duct 6. Since liquid carbon dioxide absorbs a large amount of heat during the vaporization process, when the carbon dioxide is distributed on the outside of the jacket 1 and the trouser legs 3, it will effectively achieve a cooling effect. However, it should be noted that the emission of carbon dioxide will reduce the oxygen content of the external environment, so this operation must be carried out in conjunction with the carbon dioxide bottle 16 to ensure the safety of the user.

[0031] In a further preferred embodiment of the present invention, Figure 5 - Figure 6 and Figure 1 As shown, the two gas pipes 19 are fixedly connected to the independent gas ring 20 and the top of the carbon dioxide bottle 16, and the air guide pipe 6 is fixedly connected to the output end of the gas pipe 19. At the same time, the bottom of the independent gas ring 20 is fixedly connected to a plurality of equally distributed gas outlets 8;

[0032] The independent gas supply ring 20 is consistent in structure with the second gas supply ring 5 and the first gas supply ring 4. When the operator is wearing a fire suit, the independent gas supply ring 20 is located at the neck of the operator. In addition, through an independent gas supply pipe 19, the independent gas supply ring 20 can obtain a continuous gas supply. Even if the device is damaged, thanks to the separately configured gas supply pipe 19, the vaporizer 18 can still deliver carbon dioxide to the independent gas supply ring 20, thereby ensuring the safety of the operator's life, especially the effective protection of his or her critical organs.
