[0029] Preferably, first temperature sensing trigger assembly 4 includes piston block 401 and rack 402, swing arm 3 is provided with gear structure 301 meshed with rack 402, which can convert the moving action of piston block 401 and rack 402 in frame connecting part 1 into the swinging action of swing arm 3, realizing the opening and closing of the fan body.

[0030] Preferably, piston block 401 is provided with turnover block 8 and first temperature sensing element 9, turnover block 8 is hinged to piston block 401, and first temperature sensing element 9 is abutted with turnover block 8 at one end and piston block 401 at the other end.

[0031] Preferably, the frame connecting part 1 has a trigger slot 101 corresponding to the piston block 401. When the first temperature sensing element 9 and the flip block 8 are in contact, the end of the flip block 8 away from the hinge axis abuts against the trigger slot 101, so that the piston block 401 remains fixed in position within the frame connecting part 1.

When the window sash is opened, the swing arm 3 swings away from the frame connecting part 1. The gear structure 301 on the swing arm 3 drives the rack 402 and the piston block 401 to move within the frame connecting part 1, thereby compressing the elastic reset mechanism 5. When the piston block 401 moves to the trigger slot 101, the first temperature sensing element 9 is placed between the flip block 8 and the piston block 401. One end of the first temperature sensing element 9 abuts against the flip block 8, and the other end abuts against the piston block 401.

When exposed to high temperatures, the first temperature sensing element 9 breaks, the flip block 8 loses its support force and rotates towards the side closer to the first temperature sensing element 9, releasing the abutment state with the trigger slot 101. The elastic reset mechanism 5 releases its elastic potential energy, pushing the piston block 401 and the rack 402 towards the direction closer to the pivot of the swing arm 3, thereby causing the swing arm 3 to swing towards the direction closer to the frame connection part 1.
