[0033] Please see Figures 1 to 4 This application provides a particulate cylinder fire extinguisher, including an extinguishing agent storage container 1, a lower end cap 2, an upper end cap 3, a slider 4, a pressurization tube 5, and a lead wire control unit 6. The fire extinguishing agent storage container 1 has a chamber 11 for storing the fire extinguishing agent. The edge of the lower end cover 2 is tightly connected to one end of the fire extinguishing agent storage container 1, and the lower end cover 2 has an air inlet that communicates with the chamber 11. The upper end cover 3 is located at the other end of the fire extinguishing agent storage container 1, and the upper end cover 3 has a nozzle 31 and a rupture disc 32. The rupture disc 32 seals the air passage that communicates between the nozzle 31 and the chamber 11. The slider 4 is slidably fitted inside the chamber 11, and the edge of the slider 4 is tightly fitted to the inner wall of the chamber 11. The fire extinguishing agent is stored in the chamber 11 between the slider 4 and the upper end cover 3. The pressurizing pipe 5 is connected to the air inlet through a connector 51, and the other end of the pressurizing pipe 5 is connected to a high-pressure source. An electrically controlled valve is installed inside the connector 51. The lead wire control unit 6 is electrically connected to the electrically controlled valve and is used to automatically control the opening and closing of the electrically controlled valve according to the fire situation.

[0034] The extinguishing principle of the particulate cylinder fire extinguisher of this application is as follows: When a fire occurs, the lead control unit 6 (which can be activated automatically via a temperature sensor, a thermal wire 61, etc., or manually) detects the fire and controls the opening of the electronically controlled valve. This allows high-pressure gas from a high-pressure source (such as a high-pressure cylinder) to enter the chamber 11 through the pressurization pipe 5, thereby pushing the slider 4 towards the upper end cover 3. The slider 4 pushes and squeezes the extinguishing agent, causing the pressure in the chamber 11 to increase rapidly until it ruptures the rupture disc 32 (Figure 3). Figure 4 As shown in the figure, the extinguishing agent is sprayed from the nozzle 31 through the upper end cover 3. The nozzle 31 can be pre-aimed at the fire prevention zone, so that the extinguishing agent sprayed from the nozzle 31 can extinguish the fire.

[0035] In one embodiment, the lead control unit 6 includes a thermal wire 61 and a start wire 62. The other end of the thermal wire 61 is laid in the fire protection zone, and the other end of the start wire 62 is connected to a manual start button.

[0036] The thermally sensitive wire 61 is laid in the fire protection zone. When a fire occurs, the thermally sensitive wire 61 senses the high temperature generated by the fire source and responds quickly, transmitting a signal to the lead control unit 6, which in turn controls the opening of the electrically controlled valve and initiates the fire extinguishing procedure. Simultaneously, the activation wire 62 connects to a manual activation button, allowing personnel to manually press the button after discovering a fire, which also triggers the opening of the electrically controlled valve, activating the fire extinguisher. This design combines automatic and manual activation methods, ensuring that the fire extinguisher can be quickly and effectively deployed in various situations.

[0037] By setting up a thermal wire 61 and an activation wire 62, a dual activation mechanism for the fire extinguisher is realized. It can automatically detect and activate the fire extinguisher when a fire occurs through the thermal wire 61, and can also be activated by pressing the manual activation button after a fire is discovered by a person, which greatly improves the flexibility and response speed of the fire extinguisher.

[0038] In one embodiment, the lead control unit 6 further includes a feedback line 63, one end of which is connected to the electrically controlled valve, and the other end of which is connected to the background monitoring system.

[0039] Feedback line 63 is connected at one end to the electrically controlled valve and at the other end to the back-end monitoring system. When the electrically controlled valve opens or closes, feedback line 63 transmits a corresponding signal to the back-end monitoring system, indicating the working status of the fire extinguisher. At the same time, if the thermal line 61 detects a fire, this information will also be transmitted to the back-end system via feedback line 63, enabling supervisory personnel to quickly understand the fire situation and respond in a timely manner.

[0040] By adding feedback line 63, this claim enables real-time feedback of the working status of the electrically controlled valve and the fire status, allowing the background monitoring system to promptly learn about the operation of the fire extinguisher and the situation at the fire scene, providing important decision-making basis for supervisors and helping to take further fire extinguishing or evacuation measures in a timely manner.

[0041] In one embodiment, the device further includes a support assembly 7, which is installed at both ends of the extinguishing agent storage container 1. The support assembly 7 is specifically made of a high-strength metal material (such as aluminum alloy) to support the weight of the fire extinguisher and maintain its stability. During installation, simply fixing the support assembly 7 in the predetermined position securely installs the fire extinguisher in the fire prevention area for easy access.

[0042] The addition of bracket assembly 7 facilitates the installation and fixation of fire extinguishers, enabling them to be stably installed in fire prevention and control areas and ensuring that they can be used quickly and accurately in the event of a fire.

[0043] In one embodiment, the extinguishing agent is perfluorohexanone (PFH). PFH is a highly efficient and clean extinguishing agent with excellent fire extinguishing performance and environmentally friendly characteristics. When the fire extinguisher is activated, PFH is rapidly sprayed onto the fire scene, extinguishing the fire through a combination of physical cooling and chemical inhibition. For specific types of fire sources, such as lithium battery fires, PFH can rapidly reduce the temperature of the fire source and inhibit its spread without polluting the surrounding environment.

[0044] In one embodiment, the extinguishing agent storage container 1 is made of aluminum alloy. Aluminum alloy has excellent properties such as low density, high strength, and good corrosion resistance. Making the extinguishing agent storage container 1 of aluminum alloy can significantly reduce the weight of the fire extinguisher, making it easier for personnel to carry and move. At the same time, the high strength and corrosion resistance of aluminum alloy also ensure the structural stability and service life of the extinguishing agent storage container 1, improving the overall performance of the fire extinguisher.

[0045] In one embodiment, the upper cover 3 is provided with a punching port, and the inner wall of the punching port is provided with a sealing connection thread. The nozzle 31 is threadedly connected to the punching port. The punching port is provided with a stepped surface, and a PTFE gasket is provided on the stepped surface. When the nozzle 31 is installed on the punching port, the end of the nozzle 31 abuts against the PTFE gasket.

[0046] The filling port is located on the upper end cover 3, and its inner wall has a sealing thread. The nozzle 31 is threadedly connected to the filling port. After the fire extinguisher is used, the nozzle 31 can be unscrewed, and the extinguishing agent storage container 1 can be refilled through the filling port (while simultaneously replacing the rupture disc 32). Then, the nozzle 31 can be reinstalled for reuse. The stepped surface and PTFE gasket design inside the filling port ensure a tight installation and sealing performance of the nozzle 31, preventing leakage of the extinguishing agent. This design allows the fire extinguisher to be reused, reducing waste and environmental pollution.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
