[0002] Kitchens, frequently using open flames and containing large amounts of flammable materials, are high-risk locations for fires. For fire safety reasons, hotels, restaurants, and other similar establishments often install fire-fighting equipment to respond promptly in the early stages of a fire. Fire extinguisher boxes, as safety devices integrating fire extinguishing equipment and materials, are primarily used for emergency fire suppression in the initial stages of a fire, ensuring the safety of personnel and property.

[0003] In existing fire extinguishing systems, only one extinguishing agent bottle is typically installed. However, the extinguishing agent capacity of a single bottle is limited, making it difficult to meet the fire extinguishing needs of large or complex fire scenarios, and the fire extinguishing effect may be insufficient. Secondly, if the extinguishing agent bottle of the fire extinguishing system malfunctions or the extinguishing agent leaks, the entire fire extinguishing system will become ineffective, seriously affecting safety.

[0004] Therefore, the structure of existing fire extinguishing devices has room for further improvement. Utility Model Content

[0053] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0054] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0055] Those skilled in the art should understand that in the disclosure of this application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0056] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 4 illustrate.

[0057] Please see Figure 1-4This application provides a technical solution: a fire extinguishing device, applied in the field of fire extinguishing device technology, including a control box 1. The control box 1 contains a high-pressure steel cylinder 11, and agent bottles 12 disposed on both sides of the high-pressure steel cylinder 11, and a liquid one-way valve 13 located between the high-pressure steel cylinder 11 and the agent bottles 12; the control box 1 also contains a water flow linkage valve 14, which is connected to an external water source, and the water flow linkage valve 14 and the two agent bottles 12 are connected through the liquid one-way valve 13; the high-pressure steel cylinder 11 is provided with a gas-liquid pipeline 111 and a high-pressure hose 112 communicating with its interior, the gas-liquid pipeline 111 being connected to one of the agent bottles 12 and in the gas... A pressure reducing valve 15 is installed on the liquid pipeline 111. The other end of the pressure reducing valve 15 is connected to another agent bottle 12. The pressure reducing valve 15 can adjust the spray pressure of the extinguishing agent, so that the extinguishing mixture can be sprayed more evenly on the fire area and enhance the extinguishing effect. The high-pressure steel cylinder 11 is also equipped with a release mechanism 16. One end of the release mechanism 16 is connected to the high-pressure hose 112, and the other end of the release mechanism 16 is connected to the pressure reducing valve 15. The release mechanism 16 is a mechanical or electronic device used to trigger and activate the extinguishing device to release the extinguishing agent. Its main function is to release the extinguishing agent quickly and reliably in emergency situations, thereby effectively extinguishing the fire and preventing the fire from spreading. Both extinguishing agent bottles 12 are equipped with container valves 17, which are located on the top of the bottles. The bottles 12 are connected to a water flow linkage valve 14 via the container valves 17 and a liquid check valve 13. The container valves 17 are devices used to control the flow and shut-off of the extinguishing agent in the bottles 12. They typically work closely with the bottles 12 to ensure rapid and accurate release of the extinguishing agent when needed. In the event of a fire, the water flow linkage valve 14 responds quickly, opening the water supply and connecting to the bottles 12 via the liquid check valve 13. This allows the water to mix with the extinguishing agent before being sprayed out, achieving the fire extinguishing effect.

[0058] The fire extinguishing device of this application, by setting two agent bottles 12, can improve the reliability of the fire extinguishing system, expand the fire extinguishing coverage and enhance the fire extinguishing effect compared with a single agent bottle 12, thus meeting the fire extinguishing needs of large or complex fire scenarios. Moreover, when one agent bottle 12 malfunctions or the extinguishing agent leaks, the other agent bottle 12 can still work normally, which greatly improves the reliability and safety of the fire extinguishing system.

[0059] Furthermore, such as Figure 2As shown, the two extinguishing agent bottles 12 are designated as a first extinguishing agent bottle 121 and a second extinguishing agent bottle 122. A high-pressure steel cylinder 11 is positioned at the center of the control box 1. The first extinguishing agent bottle 121 and the second extinguishing agent bottle 122 are symmetrically arranged on the left and right sides of the high-pressure steel cylinder 11. The first extinguishing agent bottle 121 and the second extinguishing agent bottle 122 are of equal size. Their central placement ensures the stability of the fire extinguishing device's center of gravity, reduces the risk of damage due to vibration or impact, and enhances overall safety performance. Both the first extinguishing agent bottle 121 and the second extinguishing agent bottle 122 are equipped with extinguishing agent tubing, which connects to a container valve 17 to facilitate the delivery of the extinguishing agent. The independent tubing connecting the first extinguishing agent bottle 121 and the second extinguishing agent bottle 122 to the container valve 17 allows for phased or area-specific release of the extinguishing agent, improving extinguishing efficiency and targeting.

[0060] Furthermore, such as Figure 2 As shown, the control box 1 also includes two water connection hoses 19. The water flow linkage valve 14 is located in the middle of the first agent bottle 121 and the high-pressure steel cylinder 11. The side of the water flow linkage valve 14 is provided with at least two water outlets. The first agent bottle 121 and the second agent bottle 122 are respectively connected to the water outlets of the water flow linkage valve 14 through the two water connection hoses 19. By setting multiple water outlets, multiple agent bottles 12 can be connected simultaneously or separately, supporting independent or linkage control of multiple bottles, which facilitates flexible adjustment of the system configuration according to different fire extinguishing needs.

[0061] The working principle of the fire extinguishing device is as follows: When a fire occurs, the high-pressure gas in the high-pressure cylinder 11 is activated by releasing the release mechanism 16, which quickly squeezes out the extinguishing agent in the agent bottle 12 and enters the water flow linkage valve 14 through the liquid one-way valve 13. At the same time, the water flow linkage valve 14 opens the external water source. The extinguishing agent and water mix to form an extinguishing mixture, which is delivered to the corresponding spraying positions of the first agent bottle 121 and the second agent bottle 122 through the water connection hose 19 to achieve rapid fire extinguishing.

[0062] Furthermore, such as Figure 4As shown, the container valve 17 includes a valve body 171, a valve cover 172, and a nut 173. The valve body 171 is connected to the valve cover 172. The nut 173 is at least partially fitted onto the valve cover 172 and at least partially fitted onto the valve body 171. The valve body 171 has a cavity for accommodating the agent tube, which is at least partially housed within the valve body 171, ensuring that the extinguishing agent can flow smoothly from the agent bottle 12 through the valve body 171 into the agent tube. The valve cover 172 is positioned above the valve body 171 and has an external connection port. The valve cover 172 cooperates with the valve body 171 to provide a seal and protection, preventing leakage of the extinguishing agent. A protective film 175 is provided between the valve cover 172 and the valve body 171. The protective film 175 serves as a sealing layer to prevent external dust, moisture, and impurities from entering the connection between the valve body 171 and the valve cover 172, avoiding corrosion or contamination. The valve cover 172 is provided with an annular protrusion 1721, and the nut 173 is provided with a mating part. The annular protrusion 1721 and the mating part are mated to realize the connection between the valve cover 172 and the nut 173.

[0063] The valve body 171 has a threaded end facing the medicine bottle 12, and the medicine bottle 12 has a threaded hole; or the valve body 171 has a threaded hole facing the medicine bottle 12, and the medicine bottle 12 has a thread, and the valve body 171 and the medicine bottle 12 are threadedly connected. The threaded connection can facilitate the disassembly and installation of the container valve 17 and the medicine bottle 12, improve maintenance efficiency, and at the same time, under the action of high pressure gas, the threaded connection can also prevent the container valve 17 and the medicine bottle 12 from loosening or leaking, ensuring the normal operation and safety of the fire extinguishing device.

[0064] The valve cover 172 is provided with threads, and the nut 173 is provided with threaded holes; or the valve cover 172 is provided with threaded holes, and the nut 173 is provided with threads; the valve cover 172 and the nut 173 are threadedly connected, and the threaded connection enables the valve cover 172 and the nut 173 to fit tightly together, enhance the sealing performance of the valve body 171, and prevent the extinguishing agent from leaking in an uncontrolled manner.

[0065] A sealing ring 174 is provided between the valve body 171 and the agent bottle 12. The sealing ring 174 can further enhance the sealing performance between the valve body 171 and the agent bottle 12, prevent leakage of extinguishing agent during storage and release, and enhance the reliability of the seal.

[0066] The valve body 171 has a connecting hole on the side facing the liquid check valve 13, and the valve body 171 is connected to the liquid check valve 13 through the connecting hole; the connecting hole has a threaded hole, and the liquid check valve 13 has threads, and at least part of the liquid check valve 13 is threadedly connected to the valve body 171. The threaded connection can facilitate the replacement and maintenance of the liquid check valve 13, save costs and maintenance time, and improve maintenance efficiency.

[0067] Furthermore, such as Figure 3As shown, the release mechanism 16 includes a base 161, which is cylindrical in shape. Compared to the traditional square base 161, the cylindrical base 161 saves materials and reduces costs. A first protrusion 1611 is provided on the side of the base 161 facing the first medicine bottle 121, and a second protrusion 1612 is provided on the side facing the second medicine bottle 122. The first protrusion 1611 and the second protrusion 1612 are symmetrical about the center of the base 161. The first protrusion 1611 and the second protrusion 1612 are located at the end of the base 161 near the high-pressure cylinder 11. The first protrusion 1611 and the second protrusion 1612 protrude in a direction away from the center of the base 161. A first connecting rod is provided inside the first protrusion 1611. The second boss 1612 has a second connecting hole, and the first connecting hole and the second connecting hole communicate with the inner cavity of the base 161. The first connecting hole and the second connecting hole are threaded holes. By setting the protruding first boss 1611 and second boss 1612, the number of joints can be reduced, water leakage can be avoided, and costs can be saved. Furthermore, by setting the threaded holes, as long as the depth of the first boss 1611 and the second boss 1612 is sufficient, the pressure reducing valve 15 or the high-pressure hose 112 can be directly screwed in without joints.

[0068] Furthermore, such as Figure 2 As shown, the first connection hole of the base 161 is connected to the first agent bottle 121 and the second agent bottle 122 respectively through the pressure reducing valve 15; the second connection hole of the base 161 is connected to the water flow linkage valve 14 through the high pressure hose 112; the control box 1 also includes a connecting hose 18, one end of the pressure reducing valve 15 is connected to the liquid check valve 13 on the first agent bottle 121 through the gas-liquid pipeline 111, and the other end of the pressure reducing valve 15 is connected to the liquid check valve 13 on the second agent bottle 122 through the connecting hose 18. The connecting hose 18 is used to transmit the gas regulated by the pressure reducing valve 15 to the second agent bottle 122 to drive the extinguishing agent in the second agent bottle 122 to flow out, so that the two agent bottles 12 can work in coordination to jointly provide the extinguishing agent required for fire extinguishing.

[0069] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas.
