[0002] Ventilation skylight refers to ventilation equipment used on steel structure roofs or roofs made of other materials. It can maintain indoor and outdoor air circulation to keep the indoor air fresh and adjust the indoor temperature and brightness.
[0003] Existing ventilation skylights usually adopt a multi-layer structure distributed up and down, each layer of the structure includes a number of spaced plates, the multi-layer structure is staggered to form an air flow channel, and drainage ditches are set on some plates to drain rainwater to a designated location. Ventilation skylights can prevent rain and snow, and keep indoor and outdoor air flowing.
[0004] When it rains, there are torrential rain, heavy rain, moderate rain, light rain and other forms. The heavier the rain, the bigger the raindrops. As we all know, when the raindrops are large, they will splash everywhere when hitting the ventilation skylight, causing rainwater to enter the room. Therefore, it is necessary to increase the number of panels in the ventilation skylight to avoid this situation, which leads to a larger thickness of the ventilation skylight.

[0024] Please refer to Figure 1As shown, an embodiment of the present invention provides a rain and snow proof ventilation skylight 10, which can be installed on a steel roof, a wooden roof, a tile roof, etc. The rain and snow proof ventilation skylight 10 can not only maintain indoor and outdoor air circulation, but also prevent rain, snow, mosquitoes, debris, etc. from entering the room.
[0025] The specific structure of the rain and snow proof ventilation skylight 10 is as follows: the rain and snow proof ventilation skylight 10 is mainly composed of a frame 11, a rain and snow proof layer 12 and a drainage layer 13. The rain and snow proof layer 12 and the drainage layer 13 are installed in the frame 11. The rain and snow proof layer 12 and the drainage layer 13 are distributed in the up and down direction. Specifically, the rain and snow proof layer 12 is located above the drainage layer 13. The following is a detailed discussion of each component of the rain and snow proof ventilation skylight 10.
[0026] The structure of the frame 11 is not limited, and can be roughly a rectangular frame structure, with the middle portion of the frame 11 exposed. Of course, in other embodiments, the frame 11 can also be a circular frame structure, a polygonal frame structure, an irregular frame structure, and the like.
[0027] The four sides of the frame 11 can be fixed to the roof or other parts, and the connection method between the two is not limited, for example, connection through threaded fasteners, welding, connection through rivets and other methods.
[0028] The material of the frame 11 is not limited, and can be stainless steel, aluminum, plastic, etc. The size of the frame 11 can be set as needed, which will not be repeated here. The size and thickness of the frame 11 are not limited and can be set as needed. In this embodiment, due to structural changes, the thickness can be reduced to 450mm.
[0029] The rain and snow protection layer 12 is distributed inside the frame 11 and covers or substantially covers the middle part of the frame 11. Specifically, the rain and snow protection layer 12 includes a plurality of waterproof boards 120 and a plurality of dense mesh boards 121, wherein the waterproof boards 120 and the dense mesh boards 121 can be flat plate structures or corrugated plate structures.
[0030] The number and length of the waterproof board 120 and the dense mesh board 121 can be set as needed, as long as it is ensured that the laid rain and snow protection layer 12 can cover the hollow part of the frame 11.
[0031] The two ends of the waterproof plate 120 and the dense mesh plate 121 are respectively connected and fixed to the two inner walls of the frame 11, and the connection method is not limited, such as plug-in, connection through threaded fasteners, welding, integral molding, etc.
[0032] In this embodiment, the waterproof board 120 adopts a flat plate structure, which can completely block the passage of rainwater. The multiple waterproof boards 120 can be parallel to each other or arranged at an angle, which can be 5°, 10°, etc. A channel is formed between two adjacent waterproof boards 120, and the channel allows air to flow. Of course, in other embodiments, the waterproof board 120 can also be made of a plate with a bent cross-section.
[0033] The dense mesh plate 121 is provided with a plurality of mesh holes, and the number of mesh holes can be set as needed, ranging from a dozen mesh holes to a mesh structure. When raindrops fall on the dense mesh plate 121, the raindrops can be broken up by the mesh edges of the dense mesh plate 121 to form smaller water droplets, which are difficult to splash even if they fall on other planes. In addition, the dense mesh plate 121 can completely seal the passage between two adjacent waterproof plates 120 while maintaining normal air circulation, which can effectively prevent mosquitoes, debris, etc. from entering the passage.
[0034] The waterproof boards 120 and the dense mesh boards 121 are alternately distributed and form a serrated shape, that is, the two ends of the waterproof board 120 are respectively connected to two dense mesh boards 121, and the two ends of the dense mesh board 121 are respectively connected to two waterproof boards 120. In this embodiment, adjacent waterproof boards 120 and dense mesh boards 121 are connected end to end and are distributed in a V shape or an inverted V shape.
[0035] Generally speaking, the top of the waterproof board 120 is connected to the top of the dense mesh board 121. Of course, it is also possible to slightly offset the position. In some embodiments, the bottom of the waterproof board 120 is connected to the middle part or the lower part of the dense mesh board 121, or the bottom of the dense mesh board 121 is connected to the middle part or the lower part of the waterproof board 120.
[0036] The angle between the waterproof plate 120 and the dense mesh plate 121 is not limited, for example, it can be 30°, 60°, 90°, etc. In this embodiment, the angle between the two is 90°, that is, the waterproof plate 120 and the dense mesh plate 121 are perpendicular. Such an arrangement makes the rain and snow proof ventilation skylight 10 have a better rain and snow proof effect.
[0037] After passing through the dense mesh plate 121 , rainwater will fall below the rain and snow protection layer 12 , and then be blocked, collected, and discharged through the drainage layer 13 .
[0038] Specifically, the drainage layer 13 includes a plurality of drainage boards 130. The number of the drainage boards 130 can be set as needed, and can be more or less. In the present embodiment, the number of the drainage boards 130 can be the same as or similar to the number of the dense mesh boards 121, and the plurality of drainage boards 130 are distributed at intervals.
[0039] Generally speaking, the projections of two adjacent drain boards 130 on the horizontal plane partially overlap, so as to ensure that the water droplets dispersed by the dense mesh plate 121 will not fall into the room through the channel between the two drain boards 130 .
[0040] The drain board 130 can block water droplets. Since the volume of water droplets is small enough, when water droplets fall onto the drain board 130, they will not splash, but will only flow down along the inclined direction of the drain board 130. Specifically, the drain board 130 is provided with an inclined downstream surface 131, and a drainage ditch 132 is provided at the bottom of the drain board 130. The drainage ditch 132 is located at the bottom of the downstream surface 131. The water droplets collected by the downstream surface 131 can flow into the drainage ditch 132 under the action of their own gravity. The drainage ditch 132 will flow the collected water along the length direction of the drain board 130 to the collection channel at the side wall of the frame 11 or directly discharge it to the outside of the frame 11.
[0041] If the waterproof plate 120 and the dense mesh plate 121 are integrally formed or welded, there is no gap between the two, and no further processing is required. However, generally speaking, the waterproof plate 120 and the dense mesh plate 121 are independently produced and processed, and then installed in the frame 11, which will cause a gap to exist in the connection part between the waterproof plate 120 and the dense mesh plate 121, and rainwater will enter the rain and snow proof ventilation skylight 10 through the gap. Therefore, in this embodiment, the following technical solution can be adopted to improve this situation: the rain and snow proof layer 12 includes a first connecting member 122.
[0042] The cross section of the first connecting member 122 is inverted V-shaped, and the first connecting member 122 is connected and covered on the top of the waterproof plate 120 and the top of the dense mesh plate 121, so that the gap between the top of the waterproof plate 120 and the top of the dense mesh plate 121 is blocked, and rainwater does not enter the gap. The connection method of the first connecting member 122 and the waterproof plate 120 or the dense mesh plate 121 is not limited, for example, by bolt connection, welding, etc.
[0043] In addition, the rain and snow protection layer 12 includes a second connecting member 123, and the bottom end of the waterproof plate 120 and the bottom end of the dense mesh plate 121 are connected by the second connecting member 123. The second connecting member 123 includes a first part with a "<"-shaped cross section and a vertical second part, and the top of the second part is connected to the bottom end of the first part. The two parts of the first part are respectively connected and fixed to the bottom end of the waterproof plate 120 and the bottom end of the dense mesh plate 121, and the connection method is not limited, such as bolt connection, welding, etc.
[0044] When it rains, the falling direction of raindrops will be tilted due to the effect of wind direction. After the raindrops pass through the dense mesh plate 121, the scattered water droplets will also be affected by this. If the dense mesh plate 121 and the downstream surface 131 are not oriented in the right direction, some water droplets may fall into the room through the channel between two adjacent drainage plates 130. Therefore, in some embodiments, the following scheme may be adopted but is not limited to: the dense mesh plate 121 and the downstream surface 131 are arranged opposite to each other. In this way, the water droplets scattered by the dense mesh plate 121 can only fall on the downstream surface 131, and flow along the downstream surface 131 to the drainage ditch 132 to be discharged.
[0045] Of course, in other embodiments, the rain and snow protection layer 12 and the downstream surface 131 may be arranged opposite to each other, and the dense mesh plate 121 may be parallel or approximately parallel to the downstream surface 131. However, in this case, the density, angle, size, etc. of the drainage board 130 need to be adjusted.
[0046] The structure of the downstream surface 131 is not limited, and it can be a plane, or the following scheme can be adopted: the downstream surface 131 includes at least two slopes connected in sequence, and the slopes of at least two slopes gradually increase from top to bottom.
[0047] The structure of the downstream surface 131 is not limited. In this embodiment, the drainage ditch 132 includes a bottom surface and at least two sequentially connected side surfaces, and the slopes of the at least two slopes gradually decrease from bottom to top. In other embodiments, the drainage ditch 132 may include only one inclined side surface.
[0048] As for the product that has been molded and is ready for production, the specific parameters of the product are as follows: the downstream surface 131 includes a first slope surface, a second slope surface and a third slope surface, the angle between the first slope surface and the second slope surface is 210°, the angle between the second slope surface and the third slope surface is 205°, the width of the first slope surface is 20mm, the width of the second slope surface is 115mm, and the length of the third slope surface is 170mm. The spacing between the third slope surface of one downstream surface 131 and the first downstream surface of another adjacent downstream surface 131 can be 151mm.
[0049] The distance between the bottom end of the drainage ditch 132 and the bottom end of the frame 11 can be 20mm. The drainage ditch 132 includes a bottom surface, a first side surface and a second side surface. The bottom surface is arranged in the horizontal direction and is connected to the bottom ends of the third slope surface and the first side surface respectively. The angle between the third slope surface and the bottom surface is 120°, the angle between the bottom surface and the first side surface is 110°, and the angle between the second side surface and the first side surface is 190°. The width of the bottom surface is 40mm, the width of the first side surface is 70mm, and the width of the second side surface is 15mm. It should be noted that the above angles are all top surface angles. The distance between the second side surface of one drainage board 130 and the second downstream surface of another adjacent drainage board 130 can be 153mm, and the distance between the second side surface of one drainage board 130 and the third downstream surface of another adjacent drainage board 130 can be 150mm.
[0050] After repeated verification by technical personnel, this size and angle can provide maximum protection against rain and snow, and the test effect is better.
[0051] The working principle of the rain and snow proof ventilation skylight 10 provided by the present invention is as follows: when rainwater falls, it must first pass through the rain and snow proof layer 12, and the rainwater cannot pass through the waterproof board 120. The rainwater falling on the waterproof board 120 can only flow downward along the waterproof board 120, and the rainwater falling on the dense mesh board 121 will be scattered and fall into the drainage layer 13 through the mesh holes; the scattered rainwater flows downward along the downstream surface 131 of the drainage board 130 until it flows into the drainage ditch 132 and is discharged to both ends.
[0052] The above steps can be increased, decreased, modified, or the order can be adjusted as needed.
[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
