Its principle is to use the fire-detecting tube and the pressurized fire-extinguishing agent stored in the fire-extinguishing agent container connected to the fire-detecting tube to extinguish the fire. When the flame bakes the fire-detecting tube with internal storage pressure, the softening strength of the fire-detecting tube decreases, and the high-pressure fire-extinguishing agent in the fire-detecting tube breaks through the softened fire-detecting tube to release the fire-extinguishing agent to extinguish the fire. The advantage of the fire-detecting tube fire-extinguishing device is that it can accurately place the fire-extinguishing agent at the location where the fire occurs for precise fire extinguishing; the non-pressure storage piston structure fire extinguishing device with application number CN202222010913.4 The device comprises a main body, a piston and a gas generator; the main body has a cavity and a channel connected to the cavity; the piston is slidably arranged in the cavity along the axis of the main body, and the piston divides the cavity into a first chamber and a second chamber, the second chamber is used to accommodate a fire extinguishing agent, and the second chamber is connected to the channel. It solves the problems of high safety, high fire extinguishing efficiency, compact structure, short response time, and long maintenance-free cycle. However, the above patent still has some problems in actual use, such as the defect of easy pressure release and gas leakage, and the situation that accurate fire extinguishing cannot be achieved.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0018] The non-pressure storage fire detection tube type fire extinguishing device of the utility model embodiment is described below in conjunction with the accompanying drawings.

[0019] like Figure 1 and Figure 2 As shown, in the non-pressure storage fire detection tube type fire extinguishing device of the utility model embodiment, the fire extinguishing agent container 2 is the main body of the device. When in use, the volume of the fire extinguishing agent container 2 can be changed according to the actual use space, and auxiliary tools can be used to install it around the fire extinguishing agent container 2, and it can be fixed on the wall or wooden board, etc., so that it will not be restricted by the use space and can also save space; the top of the driving device 4 is connected to one end of the starting circuit 6 through the valve group 1, and the other end of the starting circuit 6 is fixedly connected to the detector 9, and the top of the siphon tube 5 is connected to one end of the fire detection tube 7 through the valve group 1, and the other end of the fire detection tube 7 is fixedly connected to the detector 9. The pressure sensor 8 is fixedly connected to the end, and the starting line 6 and the fire detection tube 7 can be fixed in position according to actual use, and can be fixed with a wire clip, so as to ensure that the starting line 6 and the fire detection tube 7 will not shake. The pressure sensor 8 and the detector 9 are fixed at the ends of the starting line 6 and the fire detection tube 7. After determining the use position of the pressure sensor 8 and the detector 9, the pressure sensor 8 and the detector 9 are fixed with a coil. If the position needs to be changed, the coil can be easily removed without damaging the pressure sensor 8 and the detector 9, thereby ensuring the use effect of the pressure sensor 8 and the detector 9.

[0020] A fire detection tube bursting hole 11 is opened on the surface of the fire detection tube 7, and the outer wall of the surface of the fire detection tube bursting hole 11 is densely covered with a plurality of circular holes. After the fire detection tube 7 is ruptured, the circular holes of the fire detection tube bursting hole 11 will spray the liquid in the fire extinguishing agent container 2 to a large area around the fire point, and the fire extinguishing effect is better.

[0021] After a fire occurs, the detector 9 first detects a fire signal, and the signal passes through the starting circuit 6 and the valve group 1. The drive line 44 in the drive device 4 is ignited by the open flame to ignite the driver 41. The piercing nail inside the driver 41 is used to pierce the sealing sheet 45, and the solution 46 is sprayed out from the bottle mouth of the pressure storage bottle 47 and flows into the fire extinguishing agent container 2. At the same time, pressure is generated in the fire extinguishing agent container 2 and the fire detection tube 7. The end pressure sensor 8 detects the starting signal and sends an alarm signal. The fire continues to spread. After the flame bakes the fire detection tube 7, the bursting hole 11 of the fire detection tube ruptures after the pressure is generated. Under the action of the internal pressure of the fire extinguishing agent container 2, the fire extinguishing agent 3 is released through the siphon 5, the fire detection tube 7 and the bursting hole 11 of the fire detection tube to extinguish the flame 10.
