Description

Technical Field

[0001] The utility model relates to the technical field of skylights, in particular to a skylight ventilation device. Background Art

[0002] Traditional curtain walls are generally used as walls. In some buildings with specialized lighting requirements, curtain walls can also serve as skylights. In addition to sealing between adjacent panes of glass with sealant strips, current curtain wall skylights often incorporate shielding, such as snap-on covers. This effectively prevents rainwater from directly entering the joint between the two panes. It also shields the sealant from direct sunlight, slowing its aging process and ensuring the overall seal of the skylight. It also compresses the glass ends to prevent loosening. However, some skylights also include ventilation openings between the two panes to ensure consistent air pressure inside and outside while also allowing for ventilation. However, due to the shielding design, which is typically sealed with sealant strips, long-term use can allow rainwater to seep through the gaps between the aged sealant strips and the glass, causing it to accumulate on the glass. This accumulated water can easily seep into the interior through the joints between the two panes, potentially causing leaks throughout the skylight. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the following, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, unless otherwise specified, "multiple" means two or more.

[0020] Reference Figures 1 to 3 A skylight ventilation device is shown, which is installed in the gap between two adjacent pieces of glass 11 on a curtain wall skylight 10. The curtain wall skylight 10 is provided with a mounting frame 12 between the two adjacent pieces of glass 11, including: a ventilation structure 20 and a ventilation buckle cover 40. The ventilation structure 20 is installed on the mounting frame 12, and the two sides of the ventilation structure 20 are respectively abutted against the two pieces of glass 11 through sealing members 30; the ventilation buckle cover 40 is buckled on the outward side of the ventilation structure 20, and at least one air inlet 41 is provided on one end of the ventilation buckle cover 40, and a folded ventilation groove 42 is provided in the ventilation buckle cover 40, and the ventilation groove 42 is connected to the air inlet 41, and the end of the ventilation groove 42 away from the air inlet 41 is connected to the ventilation structure 20.

[0021] Among them, in the present application, the curtain wall skylight 10 is installed on the installation main beam, and two decorative outer frames are arranged outside the installation main beam. The two decorative outer frames are interlocked and covered on the installation main beam, and the two decorative outer frames can be fixed by screws. In the present application, the installation frame 12 is set on the upper decorative outer frame, and the two pieces of glass 11 are respectively placed on the decorative outer frame on both sides of the installation frame 12, and the glass 11 and the decorative outer frame are contact-sealed by a sealing strip. The end of the glass 11 is connected to the side of the installation frame 12 by a sealing strip and a sealant, which can achieve sealing to a certain extent. In addition, in the above structure, the ventilation structure 20 is mainly used to achieve air circulation between its bottom and the glass 11, driving the water vapor accumulated inside to evaporate outward. At the same time, during the actual installation process, the ventilation structure 20 can also cooperate with the decorative outer frame to press the end of the glass 11 to prevent the glass 11 from loosening.

[0022] It should be noted that since the ventilation structure 20 is extended along the joints of the two pieces of glass 11, the ventilation structure 20 will completely cover all the joints on the entire curtain wall skylight 10, and the ventilation buckle cover 40 can also completely extend and cover the ventilation structure 20, or it can be arranged only on a part of the ventilation structure 20. This is set according to actual needs, as long as the space inside the ventilation structure 20 can be connected to the ventilation buckle cover 40.

[0023] See also Figures 1 to 3 To facilitate installation and fixation, the ventilation structure 20 includes a curtain wall base 21 and a curtain wall cover 22. The curtain wall base 21 is installed on the outward side of the installation frame 12, and its two sides abut against the two glass panes 11 via the sealing member 30. The curtain wall cover 22 is snapped onto the curtain wall base 21, and the ventilation cover 40 is snapped onto the curtain wall cover 22. The curtain wall cover 22 is provided with ventilation holes 23, which are connected to ventilation slots 42. The purpose of the curtain wall base 21 in this application is to press the ends of the glass panes 11 against the decorative outer frame, and a snap-fit ​​structure can be designed between the curtain wall cover 22 and the curtain wall base 21 to achieve a fastening. In the above embodiment, the ventilation holes 23 are connected to the ventilation slots 42. This design allows external wind pressure to drive airflow through the ventilation slots 42 and the ventilation holes 23 into the gap between the curtain wall base 21 and the glass panes 11, thereby driving the evaporation of water vapor in this area.

[0024] See also Figure 1 and Figure 3 In order to facilitate the stable installation of the ventilation buckle cover 40 on the curtain wall buckle cover 22, in one embodiment of the present application, a buckle head 43 is extended from the end of the ventilation slot 42 on the ventilation buckle cover 40, and the ventilation buckle cover 40 is fastened to the curtain wall buckle cover 22 by cooperating with the ventilation hole 23 through the buckle head 43.

[0025] See also Figure 2 To facilitate ventilation, a ventilation channel 24 is formed between the curtain wall base 21 and the curtain wall cover 22. The ventilation channel 24 connects to the ventilation slots 42 through the ventilation holes 23. A ventilation evaporation chamber 25 is formed between the curtain wall base 21 and the glass 11. Evaporation holes 26 are provided on the bottom of the curtain wall base 21. The two ends of the evaporation holes 26 connect the ventilation evaporation chamber 25 and the ventilation channel 24, respectively. The design of the ventilation channel 24 allows the entire ventilation structure 20 to be interconnected, and the ventilation cover 40 does not need to completely cover the ventilation structure 20. This ensures ventilation and removes moisture while saving costs and reducing installation difficulty.

[0026] In order to prevent rainwater from directly entering the ventilation channel 24 through the air inlet 41, in one embodiment of the present application, the end of the ventilation slot 42 is placed in the middle of the ventilation buckle cover 40, and the air inlet 41 is not in the same straight line as the end of the ventilation slot 42.

[0027] In the above-mentioned improved solution, to prevent rainwater from directly entering the ventilation channel 24 through the air inlet 41 and to enhance the strength of the entire ventilation buckle cover 40, a plurality of blocking plates 44 are provided within the ventilation buckle cover 40. The blocking plates 44 are staggered to form the ventilation slots 42. It should be noted that in this application, the ventilation slots 42 do not need to completely connect both ends of the ventilation buckle cover 40. The end of the ventilation slot 42 that connects to the ventilation structure 20 only needs to be located in the middle of the ventilation buckle cover 40.

[0028] To enhance ventilation, two air inlets 41 are provided, one on each side of one end of the vent buckle cover 40. Furthermore, in some embodiments, to increase the wind-receiving surface, the side of the vent buckle cover 40 closer to the air inlet 41 is higher than the side at the end of the ventilation slot 42. This design allows the end located at the air inlet 41 to receive greater wind pressure, thereby driving the airflow inside the vent buckle cover 40.

[0029] The present skylight ventilation device installs a ventilation structure 20 on the existing curtain wall skylight 10. The ventilation structure 20 is used to abut the two glass panels 11 through the sealing member 30, thereby achieving a second seal between the two glass panels 11. At the same time, the ventilation structure 20 itself has a ventilation function. To this end, after being connected to the ventilation buckle cover 40, the ventilation structure 20 is connected to the ventilation slot 42 by utilizing the wind pressure and the air flow in the ventilation slot 42 to achieve the internal air circulation of the ventilation structure 20. This can evaporate a small amount of accumulated water remaining at the glass panel 11, prevent the accumulated water from being in the sealant position for a long time, and prevent the sealant between the two glass panels 11 from failing. This solves the current problem of water leakage at the seam of the skylight. At the same time, the design of the folded ventilation slot 42 ensures ventilation while preventing rainwater from directly entering the room through the air inlet 41, thus meeting the waterproof requirements.

[0030] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention shall be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
