[0002] With the development of urban construction and the increase in high-rise buildings, the fire safety issues of buildings have received more and more attention. Traditional smoke exhaust skylights are usually opened manually, but when a fire occurs, it may be impossible to open them manually in time, resulting in poor smoke exhaust effect. After searching, it was found that the Chinese patent with the announcement number CN216156981U discloses a skylight for a sloping roof. In this patent, by pulling the handle, the sliding compartments at the front and rear ends of the window frame slide. Since the gravity of the sinker pulls the window frame through the steel belt, the window frame will not move downward due to its own gravity. It is necessary to manually push the handle downward gently, and the sliding rod on the window frame is stuck in the slots at different positions as needed to open the skylight. However, this patent requires manual operation to open and close the skylight, and it cannot be handled quickly in an emergency. Summary of the Invention

[0022] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0023] like Figure 1-4 As shown, a smoke exhaust skylight structure for a building comprises:

[0024] A base 1 is provided with an opening 11 suitable for exhausting smoke and a mounting frame 12;

[0025] The window frame assembly includes a window frame 21 and a window pusher 22. The window pusher 22 is hinged on the base 1, and the movable end of the window pusher 22 is hinged to the window frame 21;

[0026] A smoke detector 3 is mounted on the base 1 and faces the interior of the room. The smoke detector 3 is suitable for detecting the smoke concentration in the room.

[0027] The control device is connected to the smoke detector 3 and the window pusher 22. When the smoke detector 3 detects that the indoor smoke concentration reaches a preset value, the control device is suitable for driving the window pusher 22 to push the window frame 21 open to allow the smoke to be discharged.

[0028] In this embodiment, the window pusher 22 may be an electric push rod, the window frame 21 may be a tempered glass cover with a steel frame, the window pusher 22 is hinged to the base 1 via a hinge seat, and the window frame 21 may be transparent tempered glass.

[0029] Specifically, a sealing strip is installed on the mounting frame 12, and the sealing strip is suitable for forming a seal with the mounting frame 12 when the window pushing member 22 is moved into place and covers the mounting frame 12. In this embodiment, when the window pushing member 22 pushes the window frame 21 into place, the window frame 21 will cover the mounting frame 12, and the sealing strip is between the window frame 21 and the mounting frame 12. The setting of the sealing strip can prevent rainwater, dust, etc. from entering the room, and can also prevent noise from entering.

[0030] Specifically, if Figure 4 As shown, the smoke exhaust skylight structure of the building further includes two movable brackets 4 , one end of the movable bracket 4 is hinged to the mounting frame 12 , and the other end of the movable bracket 4 is provided with a roller.

[0031] Specifically, if Figure 4 As shown, a sliding groove 211 is further provided on the inner side of the window frame 21 , and the roller slides in the sliding groove 211 .

[0032] Specifically, if Figure 4 As shown, the smoke exhaust skylight structure of the building also includes two displacement brackets, which include a first arm 51 and a second arm 52. The first arm 51 is hinged to the mounting frame 12 through a hinge seat, and the second arm 52 is hinged to the inner side of the window frame 21 through a hinge seat. The first arm 51 and the second arm 52 are hinged.

[0033] Specifically, if Figure 4 As shown, the displacement bracket also includes a connecting member 53, one end of the connecting member 53 is connected to the hinge of one of the first arm 51 and the second arm 52, and the other end of the connecting member 53 is connected to the hinge of the other first arm 51 and the second arm 52. The connection member 53 is provided to ensure the stability and smooth sliding of the displacement bracket during the movement process, to avoid the two movable brackets from moving out of sync, causing the window frame 21 to be stuck and unable to open.

[0034] In this embodiment, when the window pusher 22 pushes the window frame 21 to move, the window frame 21 first opens upward and moves in the moving direction of the window pusher 22 through the hinged connection between the first arm 51 and the second arm 52, so that a portion of the opening 11 is exposed. The cooperation between the first arm 51 and the second arm 52 enables the window frame 21 to slide smoothly, reducing sliding resistance. When the window pusher 22 is pushed to a certain extent, the roller is exactly at the top of the sliding groove 211, limiting the movement of the window frame 21, so that the window frame 21 can be opened to a certain extent to discharge smoke, but not fully opened to prevent foreign objects from falling into the room to a certain extent.

[0035] When the smoke level drops to the preset value of the smoke detector 3 or when it rains, the window pusher 22 retracts, driving the window frame 21 to move into place, and then covers the mounting frame 12 and forms a seal with the sealing strip. This arrangement can effectively prevent rain, dust, etc. from entering the room.

[0036] Specifically, if Figure 4 As shown, a handle 212 is further provided on the inner side of the window frame 21 .

[0037] In this embodiment, when encountering special circumstances and the window pusher 22 cannot work normally, the handle 212 can be used to open and close the window frame 21.

[0038] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
