Therefore, when it is used in a building, the electric telescopic drive device 200 will not protrude or extend to the indoor side I due to the window opening or in any state, thereby interfering with the facilities to be installed (electric roller blinds) on the indoor side I. The electric smoke exhaust window will not occupy the indoor space, or will reduce the occupation of the indoor space as much as possible and increase the use area of ​​the indoor space.

[0041] See also Figure 4 According to one embodiment of the utility model, in the window closing position, the electric telescopic drive device 200 is hidden in the installation cavity 3 formed between the window frame 1 and the window sash 100, avoiding the unsightly situation caused by the electric telescopic drive device 200 being exposed when the window is closed.

[0042] See also Figure 1 In the window opening position, the angle between the window sash 100 and the window frame 1 is 90°. Compared with the traditional smoke exhaust window that can only be opened to 70°, the window opening area is increased, which can improve the smoke exhaust effect and the indoor and outdoor air exchange effect.

[0043] See also Figure 5 According to one embodiment of the utility model, the electric smoke exhaust window includes a buckle cover 2 connected to the side of the window frame 1 away from the window sash 100. The buckle cover 2 can be specifically snapped onto the window frame 1. In the window closing position, the buckle cover 2 is in sealing contact with the window sash 100 to close the installation cavity 3, thereby achieving an effect of completely hiding components such as the electric telescopic drive device 200 in the installation cavity 3.

[0044] See also Figure 4 According to an embodiment of the utility model, the power supply cable 4 of the electric telescopic drive device 200 passes through the installation cavity 3, thereby avoiding the unsightly phenomenon caused by the power supply cable 4 being exposed, and also storing the power supply cable 4 well.

[0045] See also Figures 1 to 4According to a specific embodiment of the utility model, the window sash 100 includes a window sash body 101 for closing the window frame 1 or opening the window frame 1, and a connecting plate 102 connected to the window sash body 101 on the side away from the opening direction of the window sash body 101. The fixed part is hinged to the inner side of the window frame 1, and the telescopic part is hinged to the connecting plate 102. In order to ensure that the electric telescopic drive device 200 does not always protrude to the side of the window frame 1 away from the window sash 100, it is particularly necessary to ensure that the fixed part and the inner side hinge point of the window frame 1 and the part of the electric telescopic drive device 200 around the hinge point are The electric telescopic drive device 200 never protrudes to the side of the window frame 1 away from the window sash 100, and in the window closing position, the entire electric telescopic drive device 200 does not protrude to the side of the window frame 1 away from the window sash 100. As the telescopic portion of the electric telescopic drive device 200 extends relative to the fixed portion, the window sash 100 gradually opens. During the extension process, the entire electric telescopic drive device 200 rotates around the inner hinge point between the fixed portion and the window frame 1 and swings toward the opening direction of the window sash body 101. In this way, the entire electric telescopic drive device 200 never protrudes to the side of the window frame 1 away from the window sash 100.

The first hinge 301 is connected to the first end of the first half tube 206 in the circumferential direction and the second hinge 302 is connected to the first end of the second half tube 207 in the circumferential direction. 01 and the second hinge 302 are detachably connected by a first pin 305 passing through the first through-hole and the second through-hole; the second hinge 400 includes a third hinge 401 connected to the second circumferential end of the first half tube 206 and a fourth hinge 402 connected to the second circumferential end of the second half tube 207, the third hinge 401 includes a third hole seat with a third through-hole, the fourth hinge 402 has a fourth hole seat with a fourth through-hole, the third hole seat and the fourth hole seat can be designed with reference to the first hole seat 303 and the second hole seat 304, the third through-hole and the fourth through-hole are coaxially arranged with each other and their axes are parallel to the axis of the mounting tube 205, the third hinge 401 and the fourth hinge 402 are detachably connected by a second pin 403 passing through the third through-hole and the fourth through-hole.

[0049] Of course, the first half tube 206 and the second half tube 207 can also be connected by other detachable connection methods, such as snap connection, buckle connection, etc. In addition, the mounting tube 205 is not limited to only including the first half tube 206 and the second half tube 207, but can also be composed of more parts that are detachably connected.

[0050] As a preferred embodiment, the electric telescopic drive device 200 also includes an outer sleeve 211 arranged on the outside of the mounting tube 205. When the outer sleeve 211 is provided, the outer sleeve 211 serves as a fixing part of the electric telescopic drive device 200. The outer sleeve 211 protects the mounting tube 205. The inner side of the outer sleeve 211 has a groove 212 adapted to the outer side of the first hinge 300 and the outer side profile of the second hinge 400, so that the outer sleeve 211 can be directly slid to the outside of the mounting tube 205 through the limiting adaptation of the groove 212 and the outer side of the first hinge 300 and the outer side profile of the second hinge 400. Specifically, the adaptive groove 212 on the inner side of the outer sleeve 211 can be designed based on the appearance of the first hole seat 303, the second hole seat 304, the third hole seat and the fourth hole seat. For example, when the cross-sections of the first hole seat 303, the second hole seat 304, the third hole seat and the fourth hole seat are circular, the groove 212 can be formed into a corresponding arc shape.

[0051] In addition, a first hinge seat 7 can be installed on the inner side of the window frame 1 by bolt fasteners, a second hinge seat 8 can be installed on the connecting plate 102 by bolt fasteners, the fixed part (for example, the outer sleeve 211) is hinged to the first hinge seat 7 by the first hinge shaft 9, and the telescopic part (for example, the push rod 203) is hinged to the second hinge seat 8 by the second hinge shaft 10.

Feedback signal connection: The specific connection is the fault detection sensor 213, which is installed on the transmission member 204 and is used to monitor the state of the transmission member 204. When the fault detection sensor 213 detects a fault in the transmission member 204, a corresponding signal will be generated. The signal generated by the fault detection sensor 213 is transmitted to the controller 6 through a cable. After receiving the signal from the sensor, the controller 6 will perform corresponding processing. After receiving the signal from the fault detection sensor 213, the controller 6 determines whether the transmission member 204 has a fault according to the preset logic. If the fault is confirmed, the controller 6 will trigger the alarm logic. Specifically, the alarm information can be transmitted to the mobile phone APP: the controller 6 sends the alarm information to the mobile phone APP through the communication module connected to the mobile phone APP. After receiving the alarm information, the mobile phone APP will display a corresponding warning prompt to remind the user that there is a fault in the transmission member 204. After receiving the alarm information from the mobile phone APP, the user can promptly handle the fault of the transmission member 204 to avoid further damage to the equipment or affect production.
