[0002] When building fire occurs, building structure and form are various, internal partition is complex, and after fire, large area smoke filling is easy to cause, which brings difficulty to rescue and fire extinguishing, especially combustible material produces a large amount of heat and smoke gas in the combustion process. Heat can spread outward in the mode of heat conduction, heat radiation and heat convection, fire smoke gas as the carrier of material transfer in combustion, temperature can reach 300~800 DEG C, can carry a large amount of heat and leave the combustion zone, along the door, window, corridor, stair, pipeline, hole of building and spread to other parts of building, which poses a serious threat to the trapped people and firefighters entering the building interior. And in high-rise building, high-temperature smoke gas produced by fire spreads rapidly to the upper layer along the building interior under the dual action of buoyancy and chimney effect, which makes the difficulty of blocking and controlling fire gradually increase, and three-dimensional fire is easily formed.

[0003] Experiments show that people have a death risk when contacting dense smoke for 4~5min, which is due to the scattering and absorption of solid and liquid particles in smoke gas to light, so that only part of light can penetrate the smoke gas, which greatly reduces the visibility of fire scene. Due to the light reduction of smoke gas, the ability of people to identify targets is greatly reduced, and the effect of accident lighting and evacuation signs is weakened. The smoke cannot be quickly exhausted in the fire scene, which increases the difficulty of rescue for firefighters, and the efficiency of fire extinguishing and rescue is greatly reduced.

[0004] The existing water-driven smoke exhaust mode has been applied for decades, but there are still problems as follows: firefighters must operate indoors, first extinguish the fire source in the room, and then spray a large amount of water mist from the nearby window to exhaust the dense smoke and a large amount of toxic gas generated by combustion in the room outside the window.

DETAILED DESCRIPTION

[0023] The embodiments of the present application will be described in detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application. All other examples obtained by those skilled in the art without making creative efforts fall within the scope of the present application.

[0024] In combination with Figure 1 , Figure 2 , Figure 3 and Figure 4 , a smoke exhaust water gun comprises a water gun body 1, one end of the water gun body 1 is connected with a water gun connecting head 2, the other end of the water gun body 1 is connected with a water delivery pipe 3, the top end of the water delivery pipe 3 is connected with a first U-shaped water pipe 4, the U-shaped bottom of the first U-shaped water pipe 4 is cross-connected with a second U-shaped water pipe 5, water outlet nozzles 6 are arranged at the outlets of the first U-shaped water pipe 4 and the second U-shaped water pipe 5, a water pipe hook 7 is arranged outside the connection between the first U-shaped water pipe 4 and the water delivery pipe 3, and a crushing end head 8 is arranged outside the cross of the first U-shaped water pipe 4 and the second U-shaped water pipe 5.

[0025] Specifically, a smoke evacuation water gun can efficiently carry out smoke dispersing and fire extinguishing operations. The water gun body 1 is the core support structure of the entire smoke evacuation water gun, made of high-strength lightweight material to ensure stability and durability during operation. Its shape design conforms to the principle of ergonomics, making it easy for firefighters to hold for a long time without feeling tired. The water gun connector 2 is installed at one end of the water gun body 1, using a standard threaded interface to facilitate quick connection with the fire water source, and also to replace different specifications or types of water gun heads to adapt to different scene requirements. On the other end, the water delivery pipe 3 is connected to the water gun body 1 through a high-strength flexible hose or rigid pipe, responsible for delivering water to the front end of the water gun.

[0026] The top end of the water delivery pipe 3 is connected to the first U-shaped water pipe 4, which not only optimizes water distribution but also increases the spraying range. The U-shaped bottom of the first U-shaped water pipe 4 is designed in a cross-shaped structure, with four-way communication with the second U-shaped water pipe 5. This layout allows water to be evenly distributed in multiple directions, improving the efficiency of smoke evacuation and fire extinguishing. At the outlet of each of the first U-shaped water pipe 4 and the second U-shaped water pipe 5, a water outlet nozzle 6 is configured. The water outlet nozzle 6 is equipped with a small nozzle inside, which can produce high-pressure fine mist, effectively dispersing smoke and reducing water waste, and protecting on-site equipment.

[0027] To enhance the functionality and practicality of the water gun, a water pipe hook 7 is cleverly arranged outside the connection between the first U-shaped water pipe 4 and the water delivery pipe 3. This hook can serve as a temporary hanging point, allowing firefighters to operate the water gun flexibly in complex environments, and also as a breaking tool to assist in clearing obstacles and opening up paths for rescue operations.

[0028] Outside the cross intersection of the first U-shaped water pipe 4 and the second U-shaped water pipe 5, a breaking end 8 is installed. The breaking end 8 is made of hard alloy material, sharp and strong, capable of easily penetrating thick smoke layers or breaking obstacles, opening a direct path for water flow to the fire source, greatly improving the efficiency of smoke evacuation and fire extinguishing.

[0029] When encountering a fire, the firefighter holds the water gun body 1, connects the water delivery pipe 3 and the first U-shaped water pipe 4 according to the actual situation, and extends them to the window. The breaking end 8 is used to break the window, and the first U-shaped water pipe 4 and the water delivery pipe 3 are fixed by hanging on the windowsill through the bending part. Starting the water gun makes the water outlet nozzle 6 form a large amount of water mist sprayed outward, forming a negative pressure to expel the indoor burning smoke and a large amount of toxic gas outside the window. Firefighters can achieve smoke evacuation and fire extinguishing effects without entering the room.

[0030] This smoke evacuation water gun, through its unique design and clever layout, achieves efficient, flexible, and multi-functional smoke evacuation and fire extinguishing effects, making it an indispensable tool in firefighting work.

[0031] In combinationFigure 4 、 Figure 5 、 Figure 6 As shown in

[0032] Specifically, the outlet end of the water delivery pipe 3 is designed with a connector 31, which not only enhances the stability of the connection between the water delivery pipe and the subsequent pipeline, but also ensures the smoothness of the water flow during transmission. The inner wall of the connector 31 is provided with internal threads, which are processed according to strict tolerance standards to ensure that the bottom of the first U-shaped water pipe 4 can be tightly and firmly connected together. The bottom of the first U-shaped water pipe 4 is also designed with matching external threads, which can form a tight waterproof barrier when tightened by rotating, effectively preventing high-pressure water flow from leaking at the connection and ensuring continuous and stable supply of water flow.

[0033] At the other end of the water delivery pipe 3, i.e. the inlet end, an external thread is provided to achieve seamless connection with the water gun connector 2. The water gun connector 2 is also designed with internal threads matching the external threads of the inlet end of the water delivery pipe 3, which can be tightly connected together by simple rotating operation. Not only is the operation simple and fast, but also the connection is reliable and can withstand high-pressure water flow from the water source, ensuring the normal operation of the entire smoke exhaust water gun system.

[0034] It is worth noting that whether it is the connection between the connector 31 and the first U-shaped water pipe 4, or the connection between the inlet end of the water delivery pipe 3 and the water gun connector 2, standardized thread specifications are adopted. Not only does it improve the interchangeability between the components of the smoke exhaust water gun, allowing firefighters to quickly replace damaged components in emergency situations, but it also facilitates daily maintenance and maintenance work, reducing the cost of use.

[0035] In order to ensure the sealing and durability of the connection, the connector 31 and the inlet end of the water delivery pipe 3 also adopt special anti-corrosion treatment technology during processing to enhance their corrosion resistance and prolong their service life.

[0036] In combination with Figure 2 、 Figure 3 and Figure 4 , the water delivery pipe 3 is spliced by multiple water pipes.

[0037] Specifically, the water delivery pipe 3, as an important component of the smoke evacuation water gun, fully considers the flexibility and convenience in actual use. To achieve this purpose, the water delivery pipe 3 is designed to be composed of multiple sections of water pipes. Each section of water pipe is made of high-strength, corrosion-resistant materials to ensure stable performance under high-pressure water flow and complex environments. These water pipes not only have sufficient strength and toughness to withstand the impact of water flow, but also have good wear resistance to extend the service life of the water delivery pipe.

[0038] In terms of splicing, both ends of each section of water pipe are designed with standardized connection interfaces. These interfaces can be threaded interfaces or quick plug-in interfaces, depending on the needs of the actual application scenario. Threaded interfaces achieve connection through rotating tightening, with the advantages of firm connection and less prone to loosening; while quick plug-in interfaces facilitate quick replacement or adjustment of the water delivery pipe in emergency situations, improving the convenience of operation.

[0039] The design of multiple sections of water pipes not only improves the flexibility of the water delivery pipe, allowing it to adjust its length and shape as needed to adapt to different working environments and spatial limitations. At the same time, this design also facilitates the transportation and storage of the water delivery pipe. During transportation, the water delivery pipe can be disassembled into multiple sections, reducing the volume and weight for easy carrying and handling; when stored, the multiple sections of water pipes can be neatly stacked or hung, saving space.

[0040] In combination with Figure 4 , Figure 5 , Figure 6 , the water pipe hook 7 is in a semicircular structure, one side of the water pipe hook 7 is parallel to the water delivery pipe 3 and forms a placing groove 9 that can hang on the window sill, and the other side of the water pipe hook 7 is provided with auxiliary support rods 13 between the outer walls of the two pipes of the second U-shaped water pipe 5.

[0041] Further, the water pipe hook 7 not only enhances the functionality of the water gun, but also greatly improves its practical value. The water pipe hook 7 is in a semicircular structure, not only making its appearance more smooth, but also conforming to the principles of ergonomics, ensuring its stability and reliability when hanging on supports such as window sills. One side of the water pipe hook 7 is parallel to the water delivery pipe 3 and cleverly forms a placing groove 9 that can hang on the window sill.

[0042] The other side of the water pipe hook 7 is provided with auxiliary support rods 13 between the outer walls of the two pipes of the second U-shaped water pipe 5. These auxiliary support rods 13 not only reinforce the hook structure, making it more durable, but also improve the stability of the hook during use. The connection parts of the auxiliary support rods 13 with the hook and the pipe are made of high-strength materials and are subjected to precise machining and welding treatment, ensuring the firmness and reliability of the connection.

[0043] Combining Figure 4 , Figure 5 , Figure 6 As shown in

[0044] Specifically, the back of each water outlet nozzle 6 is ingeniously designed with a cooling tip 10, effectively dispersing and reducing the heat generated during the operation of the nozzle, ensuring that the equipment can continue to operate efficiently and stably. These cooling tips 10 not only use high thermal conductivity materials in terms of material selection to accelerate heat conduction and dissipation, but also have their shape and layout carefully calculated to maximize the heat dissipation area and improve the heat dissipation efficiency.

[0045] To ensure that the cooling tips 10 are not contaminated by the external environment and physically damaged during non-use or maintenance, all cooling tips 10 are equipped with protective covers 14. These protective covers 14 not only have the basic protective functions of dust and water prevention, but also can to some extent isolate the influence of temperature changes on the internal precise structure of the cooling tips, prolonging their service life.

[0046] The connection between the cooling tips 10 and the protective covers 14 adopts an innovative plug-in structure, greatly simplifying the installation and disassembly process, so that users can quickly and easily complete the operation when they need to clean, inspect or replace the cooling tips, without the need for complex tools or additional auxiliary equipment. The plug-in structure also ensures the tightness and stability of the connection part, preventing loosening or falling off due to vibration or external force during use, further improving the overall safety and reliability of the system.

[0047] In addition, the design of the plug-in connection structure also takes into account the details of easy identification and operation, such as the protective cover may be provided with eye-catching markings or color coding, so that users can quickly and accurately find and operate the corresponding protective cover. At the same time, the plug-in interface may adopt anti-slip, self-locking and other designs to ensure that it will not be easily separated due to misoperation in the connected state, providing great convenience for users.

[0048] Combining Figure 2 , Figure 3 and Figure 4 As shown, all water outlet nozzles 6 use atomizing nozzles.

[0049] Further, all the water outlets 6 adopt atomizing nozzles, which not only greatly improve the functionality and efficiency of the smoke evacuation water gun, but also reflect the efficient use of water resources and in-depth consideration of environmental impact. The atomizing nozzles, through their internal precise atomizing structure, can disperse the water flow into countless tiny water mist particles. These tiny particles not only have a larger surface area, which can more effectively contact and adsorb smoke particles in the air, thereby accelerating the dilution and dispersion of smoke and improving the smoke evacuation effect. At the same time, since the water mist particles are extremely small, they can evaporate quickly, reducing the humidity impact on the site environment and avoiding secondary damage caused by large amounts of water flow.

[0050] The use of atomizing nozzles also means that a wider area can be covered under the same water flow, improving the efficiency of water resource utilization. Compared with traditional water spraying methods, atomizing nozzles can achieve the same smoke evacuation effect with less water, which is undoubtedly a more environmentally friendly and sustainable choice in the face of the current situation of water resource shortage.

[0051] As shown in Figure 1 , Figure 2 and Figure 3 , the water gun body 1 is provided with a water gun handle 11 on one side for easy holding, and a water gun control valve 12 on the other side for controlling the water flow.

[0052] Further, the water gun body 1, as the core component of the smoke evacuation water gun, fully integrates the principles of ergonomics and actual operation needs, aiming to provide the most convenient and efficient use experience for firefighters in emergency situations. On one side of the water gun body 1, a water gun handle 11 is provided for easy holding. On the other side opposite to the water gun handle 11, a water gun control valve 12 is provided for controlling the water flow. This control valve is a key component in the operation of the smoke evacuation water gun, allowing firefighters to accurately adjust the on-off, flow rate and spraying mode of the water flow according to the fire scene conditions and smoke evacuation needs.

[0053] It is worth noting that high-strength connection methods and sealing designs are adopted between the water gun body 1, the water gun handle 11 and the water gun control valve 12 to ensure that the entire water gun system can maintain a tight and stable connection under high-pressure water flow, preventing water leakage or component loosening, thereby ensuring the efficient and safe use of the smoke evacuation water gun.

[0054] As shown in Figure 1 , Figure 2 and Figure 3 , the surface of the water gun handle 11 is provided with anti-slip patterns.

[0055] Specifically, the water gun handle 11 not only concerns the comfort and stability of the firefighter when operating, but also directly relates to the safety and efficiency of the operation. The anti-slip pattern is ingeniously arranged on the surface of the water gun handle 11, which not only improves the stability of holding, but also further enhances the operation confidence of the firefighter in emergency situations. The design of the anti-slip pattern has been carefully calculated and tested, and its shape, depth and distribution have been optimized to ensure the best anti-slip effect in various environments. These patterns usually present a concave-convex form, which not only helps to increase the friction between the hand and the handle to prevent slipping in wet or greasy conditions, but also allows the firefighter to feel a clear tactile feedback when holding, thereby more accurately controlling the water gun.

[0056] When encountering a fire, the firefighter holds the water gun handle 11 on the water gun main body 1, connects the water delivery pipe and the first U-shaped water pipe 4 according to the actual situation, and then extends it to the window. The breaking end 8 is used to break the window, and the placing groove 9 formed by the water pipe hook 7 and the water delivery pipe 3 is hung on the window sill to fix it. The water gun control valve 12 is started, and a large amount of water mist is sprayed out of the window by the water outlet nozzle 6, forming a negative pressure to discharge the indoor burning smoke and a large amount of toxic gas out of the window. The firefighter does not need to enter the room to achieve the effect of smoke exhaust and fire extinguishing.

[0057] The anti-slip pattern also has certain aesthetic and recognition. Not only does it improve the overall visual effect of the water gun handle, but also allows the firefighter to quickly identify and accurately hold the handle in an emergency situation, reducing the time wasted in searching for the holding position. It is usually made of wear-resistant and corrosion-resistant materials to ensure that the clear pattern and good anti-slip performance can be maintained after long-term use and frequent operation. At the same time, the processing process of these patterns has also been finely polished and treated to avoid causing harm to the firefighter's hands due to too sharp edges or uneven surfaces.

[0058] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the technical field according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application can make equivalent replacement or change, which should be covered within the protection scope of the present application.
