When a fire breaks, the glass ball 21 is heated and broken, the blocking inclined plane b11 of the blocking slider 2221 is subjected to the pressure of water flowing downwards, the pressure generates a pushing force on the blocking inclined plane b11 in the direction towards the through hole 252, so that the blocking slider 2221 is pushed to slide backwards by the matching of the sliding guide part b3 and the guide channel 2211 until the clamping step b31 abuts against the upper edge of the through hole 252, at the moment, the blocking part b1 retreats into the guide channel 2211, the blocking part b1 does not block the water spraying channel 222, water flows through the water spraying channel 222 to impact the water splashing disc 23, the pressure of the downward water spraying pushes the water disc 23 to drive the vertical leg single body 242 and the support ring 241 to overcome the pulling force of the tension spring to pull the tension spring 243 to extend downwards, so that the water splashing disc 23 slides downwards to the normal working height, and the water flows through the water splashing disc 23 to spray around until the fire is extinguished.

The third gap provides a certain space for the plugging slider 2221 to slide in the guide channel 2211, and since the sliding guide part b3 is formed with the clamping step b31 which is higher than the abutting part b2 and corresponds to the upper edge of the through hole 252, the sliding guide part b3 is clamped at the clamping step b31, the whole plugging slider 2221 plugs the guide channel 2211, so that the plugging slider 2221 cannot fall off or be lost while water flow is prevented from flowing out through the guide channel 2211, thereby facilitating repeated use and reducing cost. Because the glass ball 21 is horizontally hidden in the through opening, the glass ball is not easy to be damaged by collision, particularly the collision of transversely swinging objects, and the cost is reduced. And the second gap provides space for the extension and contraction of the tension spring 243 to drive the support ring 241 and the vertical foot single body 242 to pull the splash pan 23 to descend and ascend. According to the fire-fighting fire extinguishing system, the support ring 241 and the vertical foot single body 242 are driven to pull the splash pan 23 to descend and ascend through the extension of the tension spring 243, so that the telescopic function is achieved, the splash pan 23 and the supporting feet 24, exposed on the ceiling, of the fire-fighting nozzle 2 are prevented from being damaged due to horizontal collision easily, the splash pan 23 and the supporting feet 24 are prevented from being damaged, resources are saved, the cost is low, the system is neat and attractive, and the practicability is high.
