Example 1:

as shown in fig. 1, 7 and 8, before an emergency fire occurs, the temperature control element 18 is normal, the glass outer shell is not broken, the outer shell 18.1 abuts against the movable block 18.2, the horizontal convex part 18.21 of the movable block 18.2 is embedded into the groove 18.31 of the movable pull tab 18.3, the movable pull tab 18.3 cannot move up and down under the action of the movable block 18.2, and the elastic element 18.5 is stressed to shrink and store elastic potential energy. Because the movable pull tab 18.3 cannot move up and down, the control bus 6 is tightened under the action of gravity of the first balancing weight 7, when an emergency fire occurs, the indoor temperature rises rapidly, the alcohol in the glass shell 18.47 expands due to heating, the glass shell 18.47 is burst, the glass shell 18.47 no longer supports against the movable block 18.3, the movable block 18.2 moves rightwards under the action of the elastic force of the elastic piece 18.5, the horizontal bulge 18.21 is no longer embedded into the first groove 18.31, the vertical displacement of the movable pull tab 18.3 is no longer restricted by the movable block 18.2, under the action of the gravity of the first balancing weight 7, the control bus 6 moves towards the first balancing weight 7, the movable pull tab 18.3 is pulled upwards, and due to the existence of the limiting piece 18.32, the first balancing weight 7 cannot pull the control bus 6 for an excessively long distance, as shown in fig. 8, when the limiting piece 18.32 touches the bottom of the outer shell 18.1, the movable pull tab 18.3 cannot be pulled continuously, preventing the control bus 6 from being pulled out. With the control bus 6 being pulled, the connecting line 5 is pulled to move leftwards, as shown in fig. 5 and 6, the connecting line 5 pulls the plug connecting rod 4.1 to drive the plug tongue 4.5 to retract into the plug seat 4.3 from the jack 4.6, at this time, the plug tongue 4.5 retracts into the plug seat 4.3, and under the action of the first spring 4.4, there is a tendency of outward ejection, the window sash 3 and the window frame 2 are no longer constrained by the closing mechanism 4, as shown in fig. 3, the window sash 3 is driven by the window opening counterweight mechanism 17 to open outwards, in order to prevent the smoke exhaust window from being impacted due to the excessively fast opening of the smoke exhaust window, the damping connecting piece 15 is arranged, so that the smoke exhaust window is subjected to a damping force in the opening process, the opening speed is not too fast, the impact force is not generated, and the damping spring 17.3 also serves to prevent the second counterweight 17.2 from generating excessive impact force. The first balancing weight 7 is limited by the limiting sleeves 13, the falling stroke of the first balancing weight 7 depends on the distance between the two limiting sleeves 13, and the positioning block 14 can prevent the first balancing weight 7 from infinitely falling to break the whole system. In principle, this makes it possible to open all the smoke windows connected to the control bus 6 quickly. After the fire is over, the handle 18.2 is pulled back downwards, the control bus 6 moves rightwards, the control bus is reset, and the bolt tongue 4.5 in the bolt seat 4.3 is ejected out of the bolt seat 4.3 under the action of the first spring 4.4.

In this embodiment, as shown in fig. 1, the window sash 3 is disposed in the middle of the window frame 2, the window sash 3 is thinner, the window frame 2 is thicker, and therefore the closing mechanism 4 is disposed inside the window frame 2, and the closing mechanism 4 is not parallel to the outer surface of the window frame 2, and therefore, a bolt extension fixing plate 4.7 is installed on the outer surface of the window frame 2, and the bolt extension fixing plate 4.7 is "L" shaped, so that the bolt can be installed conveniently, the connecting wire 5 does not need to be wound out of the window frame 2, and friction between the connecting wire 5 and the window frame 2 is avoided.
