The flexible sealing plate has a third end and a fourth end that are relatively arranged. The third end is sealed and fixed to the window sash assembly, and the fourth end extends to the side of the building counter-sill away from the skylight window.

[0011] Optionally, the first waterproof sealing assembly includes the rigid sealing plate and the flexible sealing plate, and the flexible sealing plate is located between the rigid sealing plate and the rotating connection portion.

[0012] Optionally, a water guide portion is provided at the second end of the rigid sealing plate, and the rigid sealing plate has a first surface located on one side of the skylight and a second surface opposite to the first surface, and the water guide portion is used to prevent water on the second surface from flowing back to the first surface.

[0013] Optionally, the water guide portion includes:

[0014] an arc portion, one end of the arc portion being connected to the second end, the other end of the arc portion opposite to the one end of the arc portion extending in a direction away from the second end, the axial direction of the arc portion being parallel to an end surface of the second end, the arc portion having an inner arc surface and an outer arc surface opposite to the inner arc surface, the inner arc surface facing the side where the first surface is located;

[0015] A bending portion is connected to the other end of the arc portion, and the bending portion is bent in a direction away from the first surface.

[0016] Optionally, the rotating assembly includes:

[0017] a first connecting member, wherein a first end of the first connecting member is fixed to the building countersill;

[0018] A second connecting member, wherein the first end of the second connecting member is rotatably connected to the second end of the first connecting member, and the second end of the second connecting member is fixed to the rotating connecting portion.

[0019] Optionally, the window sash assembly has a first window sash, one side of the first window sash has the rotating connection part, the side of the first window sash on which the rotating connection part is not provided is provided with a second waterproof sealing assembly, and the second waterproof sealing assembly extends to the side of the building counter-sill away from the skylight window to guide water on the first window sash to the side of the building counter-sill away from the skylight window.

[0020] Optionally, the window sash assembly comprises:

[0021] There are multiple second window sashes, each of which has the rotating connection part, and a gap is formed between adjacent second window sashes. The gap is covered with a third waterproof sealing component, and the third waterproof sealing component is fixed on any second window sash among the adjacent second window sashes.

[0022] Optionally, the plurality of second window sashes are two second window sashes arranged opposite to each other, the two second window sashes abut against each other to form a "triangle" structure, and the gap is formed at the abutting position of the two second window sashes;

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] In the embodiment of the present application, when the window sash assembly needs to be opened, the user can push the window sash assembly manually or through a power mechanism such as a motor in a first direction. Since the window sash assembly has a rotating connection portion, one end of the rotating assembly is fixed to the building's anti-sill, and the other end of the rotating assembly is fixed to the rotating connection portion, the window sash assembly can rotate around the rotating assembly in the first direction and move away from the skylight window. In this way, the window sash assembly can be opened relative to the skylight window. After the window sash assembly is opened relative to the skylight window, smoke exhaust can be performed. In other words, the smoke exhaust function of the smoke exhaust skylight is realized.

[0027] When the window sash assembly needs to be closed, the user can push the window sash assembly manually or through a power mechanism such as a motor in a second direction opposite to the first direction mentioned above. At this time, the window sash assembly can rotate around the rotating assembly in the second direction and re-cover the skylight window. In this way, the window sash assembly can be closed relative to the skylight window.

[0028] It can be seen from the above description that in the process of opening or closing the window sash assembly, the window sash assembly is achieved by rotating around the rotating assembly in the first direction or the second direction, and one end of the rotating assembly is fixed on the rotating connection part of the window sash assembly. Under normal circumstances, water on the window sash assembly will flow to the rotating connection part, causing the rotating connection part to often leak, and then cause the roof to leak. The embodiment of the present application covers the rotating connection part with a first waterproof sealing assembly and extends the first waterproof sealing assembly to the side of the building's anti-sill away from the skylight window, so as to achieve the purpose of guiding the water on the window sash assembly to the side of the building's anti-sill away from the skylight window. In this way, the water on the window sash assembly can be prevented from flowing to the rotating connection part, thereby preventing the roof from leaking.

[0029] As can be seen, the smoke exhaust skylight provided in the embodiment of the present application can effectively achieve the smoke exhaust function when the window sash assembly is opened relative to the skylight opening. When the window sash assembly is closed relative to the skylight opening, it can effectively prevent roof leaks while also providing ventilation. In other words, the smoke exhaust skylight simultaneously performs the functions of smoke exhaust, water leakage prevention, and ventilation, thus resolving the problem that smoke exhaust skylights cannot achieve both smoke exhaust and water leakage prevention.

[0049] Before explaining the technical solution of this application in detail, a brief description of the technical background involved in this application is first given.

[0050] A skylight is a window installed on the roof that provides natural light to the interior. Existing skylights are typically fixed directly to the roof. Since they are fixed and don't need to be opened, waterproofing them is relatively easy. Simply using some sealant to seal the perimeter of the skylight will meet the waterproofing requirements and prevent leaks. However, during construction, the inventors discovered that while fixed, enclosed skylights offer good lighting and waterproofing, they are unable to exhaust smoke in the event of a fire, hindering escape and avoidance. Therefore, it is necessary to improve the original fixed skylights into smoke exhaust skylights that can be opened or closed at any time. However, precisely because smoke exhaust skylights need to be able to be opened or closed at any time, waterproofing them is much more difficult than fixed skylights. Leaks are common at the rotating connection where the smoke exhaust skylight rotates relative to the roof. The related art does not provide a solution that can both exhaust smoke and effectively prevent leaks. Therefore, the present application provides a smoke exhaust skylight to address this problem.

[0051] The technical solution of the present application will be further described below with reference to specific embodiments and drawings.

[0052] Figure 1 This is a structural diagram of a smoke exhaust skylight provided in an embodiment of the present application when it is installed on a building's anti-slope. Figure 2 yes Figure 1 The cross-sectional view of the smoke exhaust skylight at position AA (the smoke exhaust skylight is installed on the anti-slope of the building).

[0053] See also Figure 1 and Figure 2 The smoke exhaust skylight is installed on the building counter-sill 100. The building counter-sill 100 is set on the roof 200 and protrudes from the upper surface of the roof 200. The building counter-sill 100 encloses a skylight window 300, which passes through the roof 200 to connect the indoor space and the outdoor space.

[0054] The smoke exhaust skylight comprises: a window sash assembly 1 , a rotating assembly 2 and a first waterproof sealing assembly 3 .

[0055] The window sash assembly 1 has a rotating connection 11. One end of a rotating assembly 2 is fixed to the building countersill 100, and the other end is fixed to the rotating connection 11. The rotating assembly 2 is used to open or close the window sash assembly 1 relative to the skylight opening 300. A first waterproof seal assembly 3 covers the rotating connection 11 and extends beyond the side of the building countersill 100 away from the skylight opening 300 to guide water on the window sash assembly 1 away from the side of the building countersill 100 away from the skylight opening 300.

[0056] In the embodiment of the present application, when the window sash assembly 1 needs to be opened, the user can manually or through a power mechanism such as a motor along the first direction ( Figure 2 The window sash assembly 1 is pushed in an upward direction (in a middle direction). Since the window sash assembly 1 has a rotating connection portion 11, one end of the rotating assembly 2 is fixed to the building countersill 100, and the other end of the rotating assembly 2 is fixed to the rotating connection portion 11, the window sash assembly 1 can rotate about the rotating assembly 2 in a first direction and move away from the skylight 300. In this way, the window sash assembly 1 can be opened relative to the skylight 300. After the window sash assembly 1 is opened relative to the skylight 300, smoke exhaust can be performed. In other words, the smoke exhaust function of the smoke exhaust skylight is realized.

[0057] When the window sash assembly 1 needs to be closed, the user can manually or through a power mechanism such as a motor along a second direction opposite to the first direction ( Figure 2 At this time, the window sash assembly 1 can be rotated around the rotating assembly 2 in the second direction and re-covered on the skylight window 300, so that the window sash assembly 1 can be closed relative to the skylight window 300.

[0058] It can be seen from the above description that in the process of opening or closing the window sash assembly 1, the window sash assembly 1 is achieved by rotating around the rotating assembly 2 in the first direction or the second direction, and one end of the rotating assembly 2 is fixed on the rotating connection part 11 of the window sash assembly 1. Under normal circumstances, water on the window sash assembly 1 will flow to the rotating connection part 11, causing the rotating connection part 11 to often leak, thereby causing the roof to leak. The embodiment of the present application covers the first waterproof sealing assembly 3 on the rotating connection part 11 and extends the first waterproof sealing assembly 3 to the side of the building counter-sill 100 away from the skylight window 300, thereby achieving the purpose of guiding the water on the window sash assembly 1 to the side of the building counter-sill 100 away from the skylight window 300. In this way, the water on the window sash assembly 1 can be prevented from flowing to the rotating connection part 11, thereby preventing the roof from leaking.

[0059] In fact, the reason why conventional fixed skylights are easy to waterproof and have good waterproofing effects is that when the skylight is fixed, it does not need to be opened or closed frequently, and the skylight is in a static setting all year round. For this structure, it only needs to be reliably sealed to basically meet the waterproofing requirements. However, for the needs of fire smoke exhaust, this application sets the skylight as a smoke exhaust skylight, that is, the skylight can be opened or closed at any time, which can be understood as the need for the skylight to have a dynamic setting. For skylights with such structural characteristics, if only ordinary sealing and waterproofing are used, the stability of the waterproof performance cannot be guaranteed, especially for the structure where the smoke exhaust skylight often needs to be opened and closed (that is, the rotating connection part 11), even if sealing and waterproofing are performed, it is easy to fail.

[0060] Therefore, one of the important invention points of the technical solution of the present application is to propose a new waterproofing idea for skylights that need to meet the smoke exhaust function. Specifically, the smoke exhaust skylight provided in the embodiment of the present application is achieved by covering the first waterproof sealing component 3 on the rotating connection part 11, and extending the first waterproof seal to the side of the building anti-slope 100 away from the skylight window 300 to avoid water leakage at the rotating connection part 11. In layman's terms, by building a "rain shelter" at the rotating connection part 11 and using a drainage waterproofing idea to avoid water leakage at the rotating connection part 11, compared to the method of avoiding water leakage at the rotating connection part 11 by sealing, the smoke exhaust skylight provided in the embodiment of the present application can achieve a water-proof function while meeting the smoke exhaust function requirements, ensuring a good and stable waterproof effect. Not only that, in daily use, the smoke exhaust skylight of the present application can also make the air circulation in the indoor space more unobstructed.

[0061] Among them, the above-mentioned building anti-ridge 100 refers to a building structure that protrudes from the upper surface of the roof 200 and is used to prevent water from flowing into the room. In the embodiment of the present application, the building anti-ridge 100 can be understood in a broad sense. For example, the building anti-ridge 100 can also be a mechanical structure that protrudes from the upper surface of the roof 200 and is used to prevent water from flowing into the room, etc. The embodiment of the present application does not limit the building anti-ridge 100 in a narrow sense.

[0062] The aforementioned rotating connection portion 11 refers to a portion of the structure on the window sash assembly 1, which can be understood as the structure on the window sash assembly 1 used to connect to the rotating assembly 2. In some exemplary embodiments, when the window sash assembly 1 is a window, the rotating connection portion 11 can refer to the window frame connecting the window sash and the rotating assembly 2. Of course, depending on the type of window sash assembly 1, the rotating connection portion 11 can also be understood as other structures on the window sash assembly 1, and this embodiment of the present application is not limited to this.

[0063] In addition, the above-mentioned rotating component 2 can refer to a hinge or any component that can enable the window sash component 1 to rotate around itself. The embodiment of the present application does not limit the rotating component 2.

[0064] Among them, when the rotating component 2 is a hinge, the principle of making the window sash component 1 rotate around the rotating component 2 is very simple, which can simplify the structure of the smoke exhaust skylight to a certain extent, making the structural design of the smoke exhaust skylight more concise and reasonable, and thus can simplify the manufacturing process of the smoke exhaust skylight to a certain extent and reduce the manufacturing cost.

[0065] There are many possible implementations of the first waterproof sealing component 3. In one of the possible implementations, see Figure 3 The first waterproof sealing assembly 3 includes a rigid sealing plate 31, which covers the rotating connection part 11. The rigid sealing plate 31 has a first end 311 and a second end 312 that are relatively arranged. The first end 311 is sealed and fixed on the window sash assembly 1, and the second end 312 extends to the side of the building anti-sill 100 away from the skylight 300. In this implementation, since the rigid sealing plate 31 covers the rotating connection part 11, and the first end 311 of the rigid sealing plate 31 is sealed and fixed on the window sash assembly 1, the water on the window sash assembly 1 will flow to the rigid sealing plate 31 through the first end 311. After the water reaches the rigid sealing plate 31, it can continue to flow along the surface of the rigid sealing plate 31 toward the second end 312 of the rigid sealing plate 31. Since the second end 312 extends to the side of the building counter-sill 100 away from the skylight window 300, the water at the rotating connection part 11 can be guided to the side of the building counter-sill 100 away from the skylight window 300 through the rigid sealing plate 31. In this way, the water on the window sash assembly 1 can be prevented from flowing to the rotating connection part 11, thereby preventing the roof from leaking.

[0066] The rigid sealing plate 31 may be a stainless steel sealing plate, a steel sealing plate, an iron sealing plate, or the like, and the present embodiment does not limit the rigid sealing plate 31. When the rigid sealing plate 31 is a stainless steel sealing plate, since the stainless steel sealing plate can avoid rusting, the service life of the smoke exhaust skylight can be increased.

[0067] It should be noted that the first end 311 of the rigid sealing plate 31 can be sealed and fixed to the window sash assembly 1 by silicone sealant, or can be sealed and fixed to the window sash assembly 1 by other means, which is not limited in the embodiment of the present application.

[0068] In some embodiments, see Figure 3Along the extension direction of the rigid sealing plate 31, the distance between the first end 311 of the rigid sealing plate 31 and the rotating component 2 can be within the range of 10cm-20cm. The applicant has found that when the distance between the first end 311 of the rigid sealing plate 31 and the rotating component 2 is within the range of 10cm-20cm, on the one hand, it can ensure that the first end 311 of the rigid sealing plate 31 is more securely fixed on the window sash assembly 1, and on the other hand, it can also avoid the rigid sealing plate 31 from being too large, thereby saving the material of the rigid sealing plate 31.

[0069] In another possible implementation, see Figure 3 The first waterproof sealing assembly 3 includes a flexible sealing plate 32, which covers the rotating connection part 11. The flexible sealing plate 32 has a third end 321 and a fourth end 322 that are relatively arranged. The third end 321 is sealed and fixed on the window sash assembly 1, and the fourth end 322 extends to the side of the building anti-sill 100 away from the skylight 300. In this implementation, since the flexible sealing plate 32 covers the rotating connection part 11 and the third end 321 of the flexible sealing plate 32 is sealed and fixed on the window sash assembly 1, the water on the window sash assembly 1 will flow to the flexible sealing plate 32 through the third end 321. After the water reaches the flexible sealing plate 32, it can continue to flow along the surface of the flexible sealing plate 32 to the fourth end 322 of the flexible sealing plate 32. Since the fourth end 322 extends to the side of the building counter-sill 100 away from the skylight window 300, the water at the rotating connection part 11 can be guided to the side of the building counter-sill 100 away from the skylight window 300 through the flexible sealing plate 32. In this way, the water on the window sash assembly 1 can be prevented from flowing to the rotating connection part 11, thereby preventing the roof from leaking.

[0070] The third end 321 of the flexible sealing plate 32 may be sealed and fixed to the window sash assembly 1 by silicone sealant, or may be sealed and fixed to the window sash assembly 1 by other means, which is not limited in this embodiment of the present application.

[0071] In yet another possible implementation, see Figure 3 The first waterproof sealing assembly 3 includes a rigid sealing plate 31 and a flexible sealing plate 32. The rigid sealing plate 31 covers the rotating connection portion 11, has a first end 311 sealed and fixed to the window sash assembly 1, and a second end 312 extending beyond the side of the building countersill 100 away from the skylight opening 300. The flexible sealing plate 32 covers the rotating connection portion 11, has a third end 321 sealed and fixed to the window sash assembly 1, and a fourth end 322 extending beyond the side of the building countersill 100 away from the skylight opening 300.

[0072] By simultaneously providing a rigid sealing plate 31 and a flexible sealing plate 32, in addition to preventing water on the window sash assembly 1 from flowing to the rotating connection part 11 through the rigid sealing plate 31, the flexible sealing plate 32 can further prevent water from flowing to the rotating connection part 11, thereby achieving a double anti-leakage effect, thereby making the anti-leakage function of the smoke exhaust skylight better.

[0073] Wherein, when the first waterproof sealing component 3 includes a rigid sealing plate 31 and a flexible sealing plate 32, in some embodiments, see Figure 3 The flexible sealing plate 32 is located between the rigid sealing plate 31 and the rotating connecting portion 11. By arranging the flexible sealing plate 32 between the rigid sealing plate 31 and the rotating connecting portion 11, the rigid sealing plate 31 can protect the flexible sealing plate 32, thereby extending the service life of the flexible sealing plate 32.

[0074] The flexible sealing plate 32 may be a butyl rubber sealing plate or the like, and the embodiment of the present application does not limit the material of the flexible sealing plate 32 .

[0075] In some embodiments, see Figure 3 The flexible sealing plate 32 can be arranged roughly in a stepped manner between the rigid sealing plate 31 and the rotating connection portion 11. Specifically, first, the flexible sealing plate 32 can be roughly downward along the end surface D1 of the rotating connection portion 11 close to the building anti-ridge 100 (i.e. Figure 3 The flexible sealing plate 32 extends a certain distance (in a downward direction) to form a first water guide surface S1. Then, it extends toward an edge L1 of the building counter-sill 100 away from the skylight opening 300 until it reaches the edge L1 to form a second water guide surface S2. After the flexible sealing plate 32 extends to the edge L1, it can be extended approximately downward again for a certain distance to form a third water guide surface S3. In this way, the flexible sealing plate 32 can form a generally stepped structure. The flexible sealing plate 32 with a stepped structure can have a downward trend from the rotating connection portion 11 to the edge L1. In this way, the flexible sealing plate 32 can guide water on the window sash assembly 1 to the side of the building counter-sill 100 away from the skylight opening 300.

[0076] Among them, in order to enable the flexible sealing plate 32 to guide the water on the window sash assembly 1 to the side of the building counter-sill 100 away from the skylight window 300 more quickly, the applicant has found through research that when the angle a1 between the first water guide surface S1 and the end surface D1 is within the range of 5°-6°, and / or the angle a2 between the second water guide surface S2 and the upper surface of the building counter-sill 100 is within the range of 5°-6°, and / or the angle a3 between the third water guide surface S3 and the side wall of the building counter-sill 100 away from the skylight window 300 is within the range of 5°-6°, the drainage speed of the flexible sealing plate 32 is faster, so that the flexible sealing plate 32 can guide the water on the window sash assembly 1 to the side of the building counter-sill 100 away from the skylight window 300 more quickly.

[0077] In some embodiments, see Figure 4 The second end 312 of the rigid sealing plate 31 is provided with a water guide portion 313, and the rigid sealing plate 31 has a first surface ( Figure 4 The lower surface of the rigid sealing plate 31 in the bottom surface) and the second surface opposite to the first surface, the water guide portion 313 is used to prevent water on the second surface from flowing back to the first surface.

[0078] Since the first surface is located on one side of the skylight window 300, that is, the first surface is the side facing the indoor space, and correspondingly, the second surface is the side facing the outdoor space, by providing the water guide portion 313, it is possible to prevent water on the second surface of the rigid sealing plate 31 from flowing back to the first surface, that is, it is possible to prevent water in the outdoor space from flowing back to the indoor space, thereby better preventing roof leaks.

[0079] In some embodiments, see Figure 4 The water guide portion 313 includes an arc portion 313a and a bent portion 313b. One end of the arc portion 313a is connected to the second end 312, and the other end of the arc portion 313a, which is opposite to the one end of the arc portion 313a, extends away from the second end 312. The axial direction of the arc portion 313a is parallel to the end surface of the second end 312. The arc portion 313a has an inner arc surface and an outer arc surface opposite the inner arc surface, with the inner arc surface facing the first surface. The bent portion 313b is connected to the other end of the arc portion 313a and bends away from the first surface.

[0080] In this way, the water on the second surface of the rigid sealing plate 31 can reach the second end 312 along the second surface in sequence, and then continue to flow along the outer arc surface of the arc portion 313a, and quickly reach the bent portion 313b under the guiding action of the arc portion 313a. After the water flows to the bent portion 313b, since the bent portion 313b is bent in the direction away from the first surface, the water can be quickly dripped from the bent portion 313b under the action of the bent portion 313b without the phenomenon of "back hook" water, thereby preventing the water on the second surface of the rigid sealing plate 31 from flowing back to the first surface, thereby better preventing the occurrence of roof leaks.

[0081] Among them, in some embodiments, the applicant has found through research that when the radius of the arc portion 313a is in the range of 25cm-30cm, on the one hand, the water-conducting performance of the arc portion 313a is better, and on the other hand, it can also avoid the rigid sealing plate 31 from interfering with the building counter-ridge 100 during the rotation of the window sash assembly 1.

[0082] In some embodiments, see Figure 3 The rotating assembly 2 includes a first connecting member 21 and a second connecting member 22. The first end of the first connecting member 21 is fixed to the building counter-sill 100. The first end of the second connecting member 22 is rotatably connected to the second end of the first connecting member 21, and the second end of the second connecting member 22 is fixed to the rotating connection portion 11.

[0083] In this way, when the window sash assembly 1 needs to be opened, the user can push the window sash assembly 1 along the first direction manually or through a power mechanism such as a motor. At this time, the first end of the second connecting member 22 can be rotated along the first direction relative to the second end of the first connecting member 21, so that the window sash assembly 1 is moved away from the skylight 300 to open the window sash assembly 1.

[0084] Similarly, when the window sash assembly 1 needs to be closed, the user can push the window sash assembly 1 along the second direction manually or through a power mechanism such as a motor. At this time, the first end of the second connecting member 22 can be rotated along the second direction relative to the second end of the first connecting member 21, so that the window sash assembly 1 is re-covered on the skylight window 300 to close the window sash assembly 1.

[0085] Among them, the first end of the second connecting member 22 can be rotatably connected to the second end of the first connecting member 21 in a variety of possible ways. In one possible implementation, the first end of the second connecting member 22 can be provided with a rotating shaft, and the second end of the first connecting member 21 can be provided with a hole, and the rotating shaft is inserted into the hole. In this way, the first end of the second connecting member 22 can be rotatably connected to the second end of the first connecting member 21.

[0086] In another possible implementation, the first end of the second connecting member 22 can be provided with a hole, and the second end of the first connecting member 21 can be provided with a rotating shaft, which is inserted into the hole. In this way, the first end of the second connecting member 22 can also be rotatably connected to the second end of the first connecting member 21.

[0087] Of course, the first end of the second connecting member 22 can also be rotatably connected to the second end of the first connecting member 21 in other possible ways. It is only necessary to satisfy that the first end of the second connecting member 22 is rotatably connected to the second end of the first connecting member 21. The embodiments of the present application will not be listed one by one here.

[0088] The first end of the first connector 21 can be fixed to the building counter-sill 100 by a threaded connection. Of course, it can also be fixed to the building counter-sill 100 by other means, which is not limited in the present embodiment. When the first end of the first connector 21 is fixed to the building counter-sill 100 by a threaded connection, in order to prevent water leakage at the connection between the first end of the first connector 21 and the building counter-sill 100, in some embodiments, a waterproof gasket can be provided on the first end of the first connector 21. The waterproof gasket is used to prevent water leakage at the connection between the first end of the first connector 21 and the building counter-sill 100. In this way, water leakage at the connection between the first end of the first connector 21 and the building counter-sill 100 can be avoided.

[0089] Similarly, the second end of the second connecting member 22 can also be fixed to the rotating connecting part 11 by means of a threaded connection. When the second end of the second connecting member 22 is fixed to the rotating connecting part 11 by means of a threaded connection, in order to avoid water leakage at the connection between the second end of the second connecting member 22 and the rotating connecting part 11, the second end of the second connecting member 22 can also be provided with a waterproof gasket. In this way, water leakage at the connection between the second end of the second connecting member 22 and the rotating connecting part 11 can be avoided.

[0090] In some embodiments, see Figure 5 The window sash assembly 1 has a first window sash 12, and one side of the first window sash 12 has a rotating connection part 11. The side of the first window sash 12 where the rotating connection part 11 is not provided is provided with a second waterproof sealing assembly 13. The second waterproof sealing assembly 13 extends to the side of the building anti-sill 100 away from the skylight window 300 to guide water on the first window sash 12 to the side of the building anti-sill 100 away from the skylight window 300.

[0091] Since the first window sash 12 is covered with the first waterproof sealing assembly 3 on one side with the rotating connection portion 11, and the second waterproof sealing assembly 13 is provided on the side of the first window sash 12 not provided with the rotating connection portion 11, and both the first waterproof sealing assembly 3 and the second waterproof sealing assembly 13 extend to the side of the building anti-sill 100 away from the skylight 300, therefore, when the window sash assembly 1 has a first window sash 12, it is possible to avoid roof leakage.

[0092] When the window sash assembly 1 has only one first window sash 12, when the first window sash 12 needs to be opened, the first window sash 12 can be opened by simply rotating it in the first direction. This is a simple implementation method and a simple structure. In addition, when the window sash assembly 1 has only one first window sash 12, the integrity of the window sash assembly 1 is also higher, thereby reducing the probability of water leakage to a certain extent.

[0093] In some embodiments, the first window sash 12 may include a window frame and a light-transmitting member disposed on the window frame. The light-transmitting member may be glass. Specifically, the light-transmitting member may be 1.52 PVB transparent tempered laminated glass. Laminated glass is relatively strong and does not produce sharp glass shards when broken, thus preventing injuries from the light-transmitting member breaking.

[0094] In some embodiments, see Figure 2 The window sash assembly 1 includes: a plurality of second window sashes 14, each second window sash 14 has a rotating connection portion 11, a gap 15 is formed between adjacent second window sashes 14, the gap 15 is covered with a third waterproof sealing assembly 16, and the third waterproof sealing assembly 16 is fixed on any second window sash 14 of the adjacent second window sashes 14.

[0095] When the window sash assembly 1 includes multiple second window sashes 14, for example, two second window sashes 14 arranged opposite each other can be opened or closed to achieve a faster and more effective smoke exhaust effect. However, at the same time, the gap 15 formed when the two second window sashes 14 are aligned will also require waterproofing. In other words, when multiple second window sashes 14 are provided, higher requirements are placed on the waterproofing of the smoke exhaust skylight. Therefore, in addition to waterproofing the position of the rotating connection portion 11, the present application further waterproofs the gap 15 between the second window sashes 14, which is another important inventive point of the present application.

[0096] Specifically, in addition to covering the first waterproof sealing component 3 on one side of the rotating connection part 11 and extending the first waterproof sealing component 3 to the side of the building anti-sill 100 away from the skylight 300, this embodiment also covers the gap 15 formed between adjacent second window sashes 14 with a third waterproof sealing component 16. The first waterproof sealing component 3 and the third waterproof sealing component 16 can prevent the roof from leaking. That is, while making the smoke exhaust speed of the smoke exhaust skylight faster, it can also prevent the roof from leaking.

[0097] In some embodiments, see Figure 2 The plurality of second window sashes 14 are two second window sashes 14 disposed opposite each other, and the two second window sashes 14 abut against each other to form a "triangle" structure. A gap 15 is formed at the abutting point of the two second window sashes 14. The third waterproof sealing component 16 is a waterproof board, which covers the gap 15, and one end of the waterproof board is fixed to either of the two second window sashes 14.

[0098] In this embodiment, since one end of the waterproof board is fixed to either of the two second window sashes 14 and the waterproof board covers the upper plate of the gap 15 formed at the abutment point of the two second window sashes 14, water leakage at the gap 15 can be avoided.

[0099] In addition, by making the two second window sashes 14 press against each other to form a "triangle" structure, the water on the second window sash 14 can quickly leave the surface of the second window sash 14, so that the water can be prevented from staying on the second window sash 14, thereby better preventing the roof from leaking.

[0100] Among them, when the two second window sashes 14 are pressed against each other to form a "triangle" structure, the slope of each second window sash 14 can be within the range of 3%-5%. When the slope of each second window sash 14 is within the range of 3%-5%, the applicant has found that the water on the second window sash 14 can be separated from the surface of the second window sash 14 more quickly, thereby better avoiding the occurrence of roof leaks.

[0101] Furthermore, when the two second window sashes 14 abut against each other to form a "triangle" structure, in order to make the waterproof board better match the "triangle" structure, in some embodiments, see Figure 6 The waterproofing board can be a "V"-shaped waterproofing board, which is inverted at the top of the "triangle" structure. This, on the one hand, can make the waterproofing board better match the "triangle" structure formed by the two second window sashes 14, thereby improving the integrity of the smoke exhaust skylight. On the other hand, due to the better water-conducting performance of the "V"-shaped waterproofing board, it can better prevent roof leaks.

[0102] In order to better avoid water leakage at the gap 15, see Figure 6 In some embodiments, a sealing strip 17 is sandwiched in the gap 15. The sealing strip 17 is fixed to one of the adjacent second window sashes 14 and abuts against the other of the adjacent second window sashes 14. Since the sealing strip 17 is fixed to one of the adjacent second window sashes 14 and abuts against the other of the adjacent second window sashes 14, the sealing strip 17 can seal the gap 15, thereby better preventing water leakage from occurring at the gap 15.

[0103] Among them, see Figure 6 The sealing strip 17 can be fixed to one of the adjacent second window sashes 14 by screws ( Figure 6 The second window sash 14 may be fixed to one of the adjacent second window sashes 14 by screws), or may be fixed to one of the adjacent second window sashes 14 by glue bonding, which is not limited in the embodiment of the present application.

[0104] In summary, the smoke exhaust skylight provided in the embodiment of the present application effectively performs its smoke exhaust function when the window sash assembly 1 is opened relative to the skylight opening 300. When the window sash assembly 1 is closed relative to the skylight opening 300, it effectively prevents roof leaks while also providing ventilation. In other words, the smoke exhaust skylight simultaneously performs smoke exhaust, water leakage prevention, and ventilation functions, thus resolving the problem that smoke exhaust skylights cannot simultaneously achieve both smoke exhaust and water leakage prevention.

[0105] The above is a detailed introduction to a smoke exhaust skylight disclosed in an embodiment of the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the smoke exhaust skylight of the present invention and its core idea; at the same time, for general technical personnel in this field, based on the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
