When a fire occurs or a large amount of smoke is generated, the actuator 2 is provided with an actuator 2, and a connecting rod is provided at the lower part of the actuator 2, and the actuator 2 is provided with a connecting rod, and the actuator 2 is provided with a rotating shaft and the valve body 1, and a blocking cover 3 is arranged on the connecting rod, and a smoke sensor 12 is arranged at one end of the blocking cover 3. A metal melting piece 13 is arranged at one end of the valve body 1. When fog occurs, flames and smoke invade the air duct, and the high temperature causes the metal melting sheet 13 on the valve body 1 to melt. When the temperature reaches a certain level, the actuator 2 drives the connecting rod to rotate, and then drives the baffle 3 to rotate, so that the valve body 1 can be closed. A slide groove 4 is arranged on the left side of the valve body 1, and a baffle 5 is slidably connected thereto. A sealing gasket 6 is arranged on the right side of the baffle 5. The sealing gasket 6 is made of a material with good sealing performance and high temperature resistance. When the baffle 3 is in a closed state, one end of the sealing gasket 6 moves to the right side of the slide groove 4. At this time, one side end face of the sealing gasket 6 is tightly attached to the side wall of the slide groove 4 and the side wall of the baffle 5, so as to seal the gap between the slide groove 4 and the baffle 5, thereby preventing smoke from passing through the gap, improving the sealing effect, and not being affected by high temperature. Temperature influence, moving blocks 7 are respectively provided on the front and rear sides of the baffle 5, through grooves 8 are respectively provided on the front and rear sides of the valve body 1, and are all arranged through the moving blocks 7, and multi-section electric telescopic rods 9 are installed on the right parts of several moving blocks 7, and fixed plates are provided on the right parts of several multi-section electric telescopic rods 9, and are all connected to the valve body 1, and intervals are provided between several multi-section electric telescopic rods 9 and the valve body 1, and a control device 10 is provided on the upper part of the valve body 1, and a time relay 11 is provided on the upper part of the valve body 1, and is electrically connected to the multi-section electric telescopic rod 9 through wires and the control device 10. When the baffle cover 3 is closed, the control device 10 supplies power to the time relay 11, and the time relay 11 supplies power to the multi-section electric telescopic rod 9. The retracting rod 9 contracts, and the baffle 5 and the sealing gasket 6 are driven to approach the baffle cover 3 through the moving block 7, and when the retracting limit is finally reached, the time set by the time relay 11 is reached, and the multi-section electric telescopic rod 9 stops working. At this time, one end of the sealing gasket 6 is tightly attached to one side of the baffle cover 3. The control device 10, the time relay 11, the multi-section electric telescopic rod 9 and the actuator 2 in this embodiment are all conventional equipment purchased on the market and well known to technicians in this field. In this patent, we only use them and have not improved their structure and function. For technicians in this field, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of their instruction manual, and they will not be described in detail here.

[0025] To sum up, when the air-conditioning terminal fire damper with early warning function is in use, when a fire occurs or a large amount of smoke is generated, flames and smoke invade the air duct, and the high temperature causes the metal melting piece 13 on the valve body 1 to melt. When the temperature reaches a certain level, the actuator 2 drives the connecting rod to rotate, and then drives the baffle 3 to rotate, so that the valve body 1 can be closed. At this time, the control device 10 supplies power to the time relay 11, and the time relay 11 supplies power to the multi-section electric telescopic rod 9. The multi-section electric telescopic rod 9 contracts and drives the baffle 5 and the sealing gasket 6 to approach the baffle 3 through the moving block 7. When the contraction limit is finally reached, the time set by the time relay 11 is reached, and the multi-section electric telescopic rod 9 stops working. At this time, one end of the sealing gasket 6 is tightly attached to one side of the baffle 3 to seal the baffle 3.
