The end of the fire detection tube away from the binary fire extinguisher structure is a sealed end. The binary fire extinguisher structure includes a tank, a bag, a valve assembly, and pressurized gas. The tank is installed inside the shell, and a bag is installed inside the tank. The output end of the bag is detachably connected to the fire detection tube through the valve assembly.

[0004] However, existing binary fire extinguishing devices also have certain shortcomings. Most existing binary fire extinguishing devices use traditional bolt fixing or adhesive connection methods, which not only results in a large amount of work required for equipment installation, but also leads to weak sealing performance and poor structural strength. Utility Model Content

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A binary fire extinguishing device includes a housing 1. An extinguishing agent bottle 2 is disposed on the inner wall of the housing 1. The extinguishing agent bottle 2 is a binary packaged perfluorohexanone, used for subsequent mixing and reaction for fire extinguishing. A plastic connector 3 is disposed on the upper part of the inner wall of the housing 1, contacting the extinguishing agent bottle 2. A conductive connector 4 is disposed on the inner wall of the plastic connector 3. The conductive connector 4 is made of stainless steel, which has good durability. A ball valve 5 is disposed on the upper part of the conductive connector 4, contacting the housing 1. A ball valve switch 6 is disposed on the right side of the ball valve 5, contacting the housing 1. The ball valve switch 6 allows for manual opening and closing control of the ball valve 5. A sealing gasket 7 is disposed between the conductive connector 4 and the extinguishing agent bottle 2.

[0023] Please see Figure 1 , Figure 2An O-ring 8 is provided between the conductive connector 4 and the plastic connector 3. The O-ring 8 can be used to seal the conductive connector 4 and the plastic connector 3. An O-ring 81 is provided between the fire extinguishing agent bottle 2 and the conductive connector 4. The O-ring 8 can be used to seal the fire extinguishing agent bottle 2 and the conductive connector 4.

[0024] Please see Figure 1 , Figure 2 The ball valve 5 is equipped with a fire detection tube inside, which is in contact with the fire extinguishing agent bottle 2 and the sealing gasket 7. The fire detection tube can detect the fire. The upper end of the outer shell 1 is equipped with an upper mounting plate by screw one, and the lower end of the outer shell 1 is equipped with a lower mounting plate by screw two. The upper and lower mounting plates can fix and protect the outer shell 1 and the supporting components.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The protective mechanism 9 includes connecting springs 91. Two evenly distributed connecting springs 91 are welded to the right side of the outer shell 1. A protective panel 92 is welded to the right end of the two connecting springs 91. Five evenly distributed rubber sheets are fixedly connected to the right end of the protective panel 92. A guide block 93 is fixedly connected to the right side of the outer shell 1. A guide shell 94 is slidably sleeved on the outer side of the guide block 93. The guide shell 94 is fixedly connected to the protective panel 92. A damping hole 95 is opened on the surface of the guide block 93. A damping ball is slidably connected to the inner wall of the guide shell 94. 96. The damping ball 96 is slidably connected to the damping hole 95. A connecting frame 97 is fixedly connected to the surface of the damping ball 96. The connecting frame 97 is slidably connected to the guide shell 94. An elastic element 98 is bonded to the horizontal part of the connecting frame 97. The other end of the elastic element 98 is bonded to the guide shell 94. Through the cooperation of the protective panel 92 and the connecting spring 91, the binary fire extinguishing device can be impact protected. Under the structure of the damping hole 95, the damping ball 96, etc., the excess deformation stress generated by the connecting spring 91 can be worn away.

[0026] The specific implementation process of this utility model is as follows: In use, the sealing gasket 7, O-ring 8, and O-ring 8 work together to ensure the sealing of the internal assembly of the binary fire extinguishing device. Under the action of the fire detection tube, the external fire situation can be detected and processed. Through the cooperation of the ball valve 5, fire extinguishing agent bottle 2, outer shell 1, plastic connector 3 and other structures, the connection between the fire extinguishing agent storage container and the valve fitting adopts an integrated snap-fit ​​fixing technology. This technology abandons the traditional bolt fixing or adhesive connection method, effectively reduces the workload required for equipment installation, and ensures the structural strength while ensuring the sealing performance.

[0027] The lower and upper mounting plates allow for the fixation of the binary fire extinguishing device to the supporting components. The protective panel 92 and connecting spring 91, among other structures, release the impact force from contact with the binary fire extinguishing device, providing effective protection. When the protective panel 92 drives the guide shell 94 to slide along the surface of the guide block 93, the damping ball 96 moves under the pressure of the inner wall of the damping hole 95, causing the connecting frame 97 to move. The elastic element 98 deforms, ultimately causing the damping ball 96 to detach from the damping hole 95. Under the action of force, the damping ball 96 slides along the surface of the guide block 93. When the damping ball 96 slides into the next damping hole 95, the elastic element 98 recovers its deformation, pulling the damping ball 96 into the damping hole 95. The structure of the damping ball 96 and damping hole 95 helps to wear down the excess deformation stress generated by the connecting spring 91, preventing excessive vibration of the connecting spring 91.
