by arranging the storage cavity 19 and the connecting hole 20, when the box body 1 is impacted and punctured by an external hard object, in order to avoid spontaneous combustion of the battery, the connecting hole 20 can be opened through the trigger unit, and then the fire extinguishing agent in the storage cavity 19 is scattered through the connecting hole 20 to extinguish the flame in the box body 1, so that the use safety of the new energy automobile battery is further improved; when the box body 1 is impacted and punctured by an external hard object, the foaming adhesive can automatically flow into the circular sealing shell 13 and drive the elastic shifting piece 17 to rotate, then the elastic shifting piece 17 can extrude the second air bag 24 when knocking the elastic pressing piece 18, compressed gas in the second air bag 24 enters the sliding groove 21 through the guide pipe 25 and pushes the baffle plate 22 to slide, further the through hole 23 is aligned with the connecting hole 20, and the fire extinguishing agent in the storage cavity 19 is scattered, so that the automatic detection function of the device can be realized, the fire extinguishing agent can be automatically scattered when the box body 1 is impacted and punctured, and the intelligence and automation degree of the device are further improved; when the gas in the second airbag 24 enters the chute 21 through the conduit 25, the movable piece 26 is directly pushed open, and then the gas flows through the larger conduit 25, so that the sliding speed of the baffle 22 is high, when the gas in the chute 21 returns to the second airbag 24 through the conduit 25, the movable piece 26 is pushed and pressed on the surface of the conduit 25, and then the gas can only flow through the smaller damping hole 27, so that the sliding speed of the baffle 22 is low, the operation can make the speed of the baffle 22 reset to be low, thereby prolonging the alignment time of the through hole 23 and the connecting hole 20, improving the sprinkling efficiency of the fire extinguishing agent, and making the fire extinguishing agent fully sprinkled; when the side wall of the box body 1 is impacted and punctured by a hard object, the first air bag 9 is extruded by the side wall of the box body 1, and then the pair of pressing blocks 29 are contacted with each other and press the storage films 28 on the two sides, so that the storage films 28 are broken, and the lubricating oil in the storage films 28 flows out and is dispersed to the inner surface of the side wall of the box body 1, so that the flowing effect of the foaming adhesive in the side wall of the box body 1 is further promoted, and the filling process of the foaming adhesive on the side wall of the box body 1 is accelerated; the cambered surfaces of the pair of pressing blocks 29 are matched with each other, so that the pair of pressing blocks 29 can be quickly aligned when being contacted with each other, and the problem that the pressing effect of the storage film 28 is poor due to mutual deviation between the pair of pressing blocks 29 is avoided.
