[0002] Chinese utility model patent CN220070638U discloses a hot-start structure for a fire extinguishing device based on temperature-sensing closure. The structure includes a housing containing a battery. The battery's circuitry is connected to the ignition head starting wire of the fire extinguishing device. The battery's circuitry is also connected to a temperature-sensing cable or a thermistor. Each end of the ignition head of the fire extinguishing device is connected to an ignition head starting wire.

[0003] The above technical solution achieves the purpose of quickly activating the fire extinguishing device after a fire is heated without using a thermal wire by using the temperature sensing and closing function of the temperature sensing cable or thermistor. However, in some places with high operating temperatures, the temperature sensing cable or thermistor may directly activate the fire extinguisher after detecting the high temperature, causing accidental activation and reducing the practicality of this structure.

[0004] Therefore, this utility model provides a temperature-sensitive fire extinguishing activation structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a temperature-sensitive fire extinguishing activation structure to solve the problems mentioned in the background. This invention can seal the fire extinguisher container through a fixed box and a sealing mechanism. By simultaneously detecting high-temperature environments through a fire detection tube and a temperature sensor, the accuracy of the detection can be improved, avoiding accidental activation and making it highly practical.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temperature-sensitive fire extinguishing activation structure, comprising a fire extinguisher canister, a container valve screwed to the top of the fire extinguisher canister, a fixed box screwed to the discharge port of the container valve, a sealing mechanism inside the fixed box, the sealing mechanism comprising a first fixed block and a second fixed block, the first fixed block and the second fixed block being fixedly installed inside the two ends of the fixed box, a plug being provided between the first fixed block and the second fixed block via a pushing mechanism, one end of the plug being inserted into the interior of the first fixed block, a spray pipe and a fire detection pipe being symmetrically fixed at the top and bottom of the fixed box, a temperature detection mechanism being provided at the top of the spray pipe, and flow channels being symmetrically opened between the top and bottom of the first fixed block and the second fixed block.

[0007] Furthermore, the first fixing block has a first through hole inside, and a rubber ring is fixedly installed on the inner wall of the first through hole, with one end of the plug inserted into the inside of the rubber ring.

[0008] Furthermore, the second fixing block has a second through hole inside, and the other end of the plug is slidably installed inside the second through hole, and a T-shaped bracket is fixedly installed on the other end of the plug.

[0009] Furthermore, a fixing plate is fixedly installed inside the second through hole on one side corresponding to the plug, and one end of the T-shaped frame is slidably installed inside the fixing plate. A spring is fixedly installed on one side of the T-shaped frame and the fixing plate on the outer side of one end of the T-shaped frame.

[0010] Furthermore, a magnet is fixedly installed inside the other end of the T-shaped frame, and an electromagnet is fixedly installed inside the second through hole corresponding to one side of the T-shaped frame.

[0011] Furthermore, a storage compartment is provided inside the other end of the fixed box. The storage compartment contains a spare battery and a control microcontroller. The electromagnet is electrically connected to the control microcontroller via wires. A sealing plate is fixedly installed at the front end of the storage compartment with screws.

[0012] Furthermore, a pressure check valve is fixedly installed at one end of the fire detection tube, the fire detection tube is located below the spray pipe, and spray nozzles are fixedly installed at equal intervals at the bottom of the spray pipe.

[0013] Furthermore, the temperature detection mechanism includes a fixing ring, which is fixedly installed on the outside of the spray pipe, and a temperature sensor is fixedly installed on the top of the fixing ring.

[0014] The beneficial effects of this utility model are as follows: This utility model's temperature-sensitive fire extinguishing activation structure can control an electromagnet through a backup battery, external power supply, and a control microcontroller. The mutual repulsion between the electromagnet and the magnet drives the T-shaped frame and the plug to move, facilitating the sealing of the fire extinguisher canister through the plug and rubber ring. Simultaneous detection of high-temperature environments via a fire detector and temperature sensor improves the accuracy of the detection, preventing accidental activation and enhancing its practicality. When the electromagnet is de-energized, the plug moves out of the first through-hole under the spring force, allowing the fire extinguisher to be sprayed simultaneously through the fire detector and the spray nozzle, thereby improving fire extinguishing efficiency.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a temperature-sensitive fire extinguishing activation structure, including a fire extinguisher canister 1. A container valve 2 is screwed onto the top of the fire extinguisher canister 1, and a fixed box 3 is screwed onto the discharge port of the container valve 2. A sealing mechanism is provided inside the fixed box 3. The sealing mechanism includes a first fixing block 12 and a second fixing block 15, which are fixedly installed inside the two ends of the fixed box 3. A plug 14 is provided between the first fixing block 12 and the second fixing block 15 through a pushing mechanism. One end of the plug 14 is inserted into the inside of the first fixing block 12. A spray pipe 5 and a fire detection pipe 9 are symmetrically fixed at the top and bottom of the fixed box 3. A temperature detection mechanism is provided at the top of the spray pipe 5. Flow channels 16 are symmetrically opened between the top and bottom of the first fixing block 12 and the second fixing block 15. The fire detection pipe 9 and the temperature detection mechanism simultaneously detect the high temperature of the fire, and control the sealing mechanism according to the detection results, thereby avoiding accidental activation of the fire extinguisher canister 1, improving the accuracy of the structure, and making it highly practical.

[0022] In this embodiment, the first fixing block 12 has a first through hole inside, and a rubber ring 13 is fixedly installed on the inner wall of the first through hole. One end of the plug 14 is inserted into the rubber ring 13. The second fixing block 15 has a second through hole inside, and the other end of the plug 14 is slidably installed inside the second through hole. A T-shaped bracket 18 is fixedly installed on the other end of the plug 14. A fixing plate 17 is fixedly installed inside the second through hole on one side corresponding to the plug 14. One end of the T-shaped bracket 18 is slidably installed inside the fixing plate 17, and one side of the T-shaped bracket 18 corresponds to the fixing plate 17. A spring is fixedly installed on the outer side of one end of the T-shaped frame 18, and a magnet is fixedly installed inside the other end of the T-shaped frame 18. An electromagnet 19 is fixedly installed inside the second through hole corresponding to one side of the T-shaped frame 18. When the electromagnet 19 is energized, a repulsive force is generated between it and the magnet, which facilitates the movement of the plug 14 through the T-shaped frame 18, so that one end of the plug 14 is inserted into the first through hole, and the discharge port of the container valve 2 is sealed by the action of the plug 14 and the rubber ring 13. The second through hole is designed to house the electromagnet 19, the fixed plate 17 and the plug 14, which facilitates the subsequent sliding of the plug 14 inside the second through hole.

[0023] In this embodiment, a storage compartment 11 is provided inside the other end of the fixed box 3. The storage compartment 11 is equipped with a spare battery and a control microcontroller. The electromagnet 19 is electrically connected to the control microcontroller via wires. A sealing plate 4 is fixedly installed at the front end of the storage compartment 11 with screws. The control microcontroller facilitates the control of the electromagnet 19 and other components, and facilitates the detection of high temperatures and fires. The sealing plate 4 facilitates the maintenance of the control microcontroller.

[0024] In this embodiment, a pressure check valve 10 is fixedly installed at one end of the fire detection tube 9. The fire detection tube 9 is located below the spray pipe 5. Spray nozzles 6 are fixedly installed at equal intervals at the bottom of the spray pipe 5. The temperature detection mechanism includes a fixing ring 7, which is fixedly installed on the outside of the spray pipe 5. A temperature sensor 8 is fixedly installed on the top of the fixing ring 7. The high temperature of the fire is detected simultaneously by the temperature sensor 8 and the fire detection tube 9, which can improve the accuracy of the detection of the structure and avoid the situation of the fire extinguisher canister 1 being opened by mistake. Fire extinguishing can be carried out conveniently through the fire detection tube 9 and the spray nozzles 6.

[0025] When using this temperature-sensing fire extinguishing activation structure, the spray pipe 5 is installed on top of locations such as cabinets and power supply rooms. The fire detection pipe 9 is installed above the equipment, close to it, and below the spray pipe 5. The temperature sensor 8 is electrically connected to the control microcontroller via a cable. The control microcontroller is also electrically connected to an external power supply via a cable. During normal use, the external power supply powers the structure, energizing the electromagnet 19 to activate it. The electromagnet 19 and the magnet generate a repulsive force, which pushes the magnet and the T-shaped bracket 18 to move the plug 14 to the left. One end of the plug 14 is inserted into the rubber ring 13 and the first through hole, facilitating the operation of the rubber ring 13. The first through hole is sealed to facilitate the sealing of the fire extinguisher canister 1. The temperature of the cabinet, power equipment, and other locations is simultaneously detected by the fire detection tube 9 and the temperature sensor 8, which can improve the detection accuracy of the structure and avoid accidental opening, making it highly practical. When a fire occurs, the fire detection tube 9 burns at the fire location, and the electromagnet 19 is de-energized according to the temperature detected by the temperature sensor 8. The plug 14 is moved out of the first through hole under the elastic force of the spring and the action of the T-shaped bracket 18. The extinguishing agent inside the fire extinguisher canister 1 is discharged into the fixed box 3 through the container valve 2, and then discharged into the spray pipe 5 and the fire detection tube 9 through the first through hole and the flow channel 16, which facilitates fire extinguishing and improves fire extinguishing efficiency.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
