A connecting rod is extended to the left from the center of the left end of the silicone sealing plug 106 and passes through the left plug 105. The end of the connecting rod is connected to a waterproof connector 104. The electric ignition head 101 and the thermistor 102 are passed through the waterproof connector 104. An annular groove is provided at the edge of the left end opening of the shell 108. An annular boss embedded in the annular groove is provided at the edge of the left end face of the left plug 105, and a sealing ring 113 is provided between the left plug 105 and the inner wall of the shell 108. A through hole I is opened in the right plug 109 at the center of the left side of the left end opening of the right-angle elbow 111, and the inner diameter of through hole I is smaller than the inner diameter of the left end opening of the right-angle elbow 111.

[0017] There is a circle of mounting annular boss 401 on the right side of the right plug 109, and two pits 402 for adjusting the nozzle position at the right end. When adjustment is needed, the pit 402 can be clamped with the convex handle of the angle grinder wrench, and the right plug 109 can be rotated to make the nozzle direction face the desired position.

[0018] Specific working principle: when a fire occurs in the control cabinet, the flame or high temperature ignites the thermistor 102, or the electric ignition head 101 is energized to ignite the solid gas-generating agent 117. The solid gas-generating agent 117 burns and undergoes a phase change, generating a large amount of gas, which pushes the piston 107 to move toward the cavity of the perfluorohexanone fire extinguishing agent 116, thereby increasing the pressure in the cavity of the perfluorohexanone fire extinguishing agent 116. When the pressure reaches the breaking strength of the aluminum baffle diaphragm 114, the aluminum baffle diaphragm 114 is broken, and the perfluorohexanone fire extinguishing agent 116 is ejected through the right plug 109, the right-angle elbow 111, and the atomizing nozzle 112 in sequence, and after gasification, the fire is extinguished in a fully flooded form.

[0019] Since the fire extinguishing device adopts the piston 107 propulsion structure, the fire extinguishing device can be installed in any installation orientation without affecting the spraying of the perfluorohexanone fire extinguishing agent 116; the sealing ring 113 at the radial position of the piston 107 is set close to the left plug 105 side, which ensures the stability of the piston 107 during operation. When the device is triggered, the gap generated by the combustion of the thermistor 102 is automatically closed by the silicone sealing plug 106, and when the solid gas generating agent 117 generates pressure, the silicone sealing plug 106 can play a sealing role without causing leakage, thereby affecting the pressure of the piston 107.

[0020] The above is only a preferred implementation of this patent. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of this patent. These improvements and substitutions should also be regarded as the scope of protection of this patent.
