Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation skylights, and in particular relates to a rain and snow proof ventilation skylight. Background Art

[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 typically feature a multi-layered structure, with each layer consisting of several spaced-apart panels. These staggered layers create airflow channels, and some panels are equipped with drainage channels to direct rainwater to designated locations. These skylights provide protection from rain and snow while maintaining indoor and outdoor air flow.

[0004] Rain can occur in various forms, including torrential downpours, heavy rain, moderate rain, and light rain. The heavier the rain, the larger the raindrops. As we all know, large raindrops can splash onto ventilation skylights, allowing rainwater to enter the room. Therefore, the number of panels within ventilation skylights needs to be increased to prevent this, resulting in thicker ventilation skylights. Furthermore, unobstructed airflow can allow mosquitoes, debris, and other items to enter the room. Utility Model Content

[0005] In view of this, the present invention aims to provide a rain and snow proof ventilated skylight. The dense mesh panels can break up raindrops into smaller droplets, which are less likely to splash when they land on the drain panels. Furthermore, the mesh panels can effectively prevent mosquitoes, debris, rain and snow from entering the room. Furthermore, because the waterproof panels and dense mesh panels are alternately arranged in a zigzag pattern, the number of layers can be reduced, thus reducing the overall thickness of the rain and snow proof ventilated skylight, thereby achieving better rain and snow protection.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0026] Furthermore, the terms “first”, “second”, etc. are merely used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0027] Please refer to Figure 1 As shown, an embodiment of the present invention provides a rain and snow proof ventilation skylight 10, which can be installed on steel roofs, wooden roofs, tile roofs, and other occasions. The rain and snow proof ventilation skylight 10 can maintain indoor and outdoor air circulation while preventing rain, snow, mosquitoes, debris, etc. from entering the room.

[0028] The specific structure of the rain and snow proof ventilation skylight 10 is as follows: the rain and snow proof ventilation skylight 10 mainly consists 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 and are arranged in the vertical direction. Specifically, the rain and snow proof layer 12 is located above the drainage layer 13. The following is a detailed discussion of the various components of the rain and snow proof ventilation skylight 10.

[0029] The structure of the frame 11 is not limited, and can be a substantially 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, etc.

[0030] 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.

[0031] 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 and will not be described in detail 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 450 mm.

[0032] The rain and snow protection layer 12 is distributed inside the frame 11 and covers or substantially covers the middle portion of the frame 11. Specifically, the rain and snow protection layer 12 includes a plurality of waterproof panels 120 and a plurality of dense mesh panels 121, wherein the waterproof panels 120 and the dense mesh panels 121 can be flat plate structures or wavy plate structures.

[0033] The number and length of the waterproof panels 120 and the dense mesh panels 121 can be set as needed, as long as the laid rain and snow proof layer 12 can cover the hollow part of the frame 11 .

[0034] 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 plugging, connection through threaded fasteners, welding, integral molding, etc.

[0035] In this embodiment, the waterproofing panels 120 are planar, completely blocking rainwater. Multiple waterproofing panels 120 can be parallel to each other or arranged at an angle, such as 5° or 10°. A channel is formed between adjacent waterproofing panels 120, allowing air to flow. In other embodiments, the waterproofing panels 120 can also be made of a panel with a curved cross-section.

[0036] The dense mesh panel 121 is provided with a number of mesh holes. The number of mesh holes can be set as needed, ranging from a dozen to a large mesh structure. When raindrops fall on the dense mesh panel 121, they are broken up by the mesh edges of the panel 121, forming smaller droplets. Even if these droplets fall on other surfaces, they are unlikely to splash. Furthermore, the dense mesh panel 121 completely seals the passage between two adjacent waterproof panels 120 while maintaining normal air circulation, effectively preventing mosquitoes, debris, and the like from entering the passage.

[0037] 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 the two dense mesh boards 121, and the two ends of the dense mesh board 121 are respectively connected to the two waterproof boards 120. In this embodiment, the 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.

[0038] Generally speaking, the top of waterproofing board 120 is connected to the top of dense mesh board 121. Of course, it is also possible to slightly offset the position. In some embodiments, the bottom of waterproofing board 120 is connected to the middle or lower portion of dense mesh board 121, or the bottom of dense mesh board 121 is connected to the middle or lower portion of waterproofing board 120.

[0039] 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. This arrangement makes the rain and snow proof ventilation skylight 10 more effective in preventing rain and snow.

[0040] 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 .

[0041] Specifically, the drainage layer 13 includes several drainage boards 130. The number of drainage boards 130 can be set as needed, more or less. In this embodiment, the number of drainage boards 130 can be the same as or similar to the number of dense mesh boards 121, and multiple drainage boards 130 are distributed at intervals.

[0042] 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.

[0043] The drain board 130 can block water droplets. Since the volume of the water droplets is small enough, when the water droplets fall on 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 end 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.

[0044] If the waterproof sheet 120 and the dense mesh sheet 121 are integrally formed or welded, there will be no gap between them, and no further processing is required. However, generally speaking, the waterproof sheet 120 and the dense mesh sheet 121 are independently produced and processed, and then installed in the frame 11. This will result in a gap at the connection between the waterproof sheet 120 and the dense mesh sheet 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.

[0045] The first connector 122 has an inverted V-shaped cross-section and is connected to and covers the top of the waterproof sheet 120 and the top of the dense mesh sheet 121. This blocks the gap between the top of the waterproof sheet 120 and the top of the dense mesh sheet 121, preventing rainwater from entering the gap. The first connector 122 can be connected to the waterproof sheet 120 or the dense mesh sheet 121 in any manner, such as by bolting or welding.

[0046] In addition, the rain and snow protection layer 12 includes a second connector 123, which connects the bottom end of the waterproof sheet 120 to the bottom end of the dense mesh sheet 121. The second connector 123 includes a first portion with a "<" cross-section and a second vertical portion, with the top end of the second portion connected to the bottom end of the first portion. The two portions of the first portion are respectively connected and fixed to the bottom end of the waterproof sheet 120 and the bottom end of the dense mesh sheet 121. The connection method is not limited, for example, by bolting, welding, etc.

[0047] When it rains, the wind direction causes the falling direction of raindrops to tilt. This also affects the water droplets that are dispersed after passing through the dense mesh plate 121. If the dense mesh plate 121 and the downstream surface 131 are not oriented correctly, some water droplets may fall into the room through the channel between two adjacent drainage plates 130. Therefore, in some embodiments, the following solution can be adopted, but is not limited to: the dense mesh plate 121 and the downstream surface 131 are arranged opposite each other. In this arrangement, the water droplets dispersed 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 for discharge.

[0048] 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 plate 130 need to be adjusted.

[0049] The structure of the downstream surface 131 is not limited. 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.

[0050] 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.

[0051] For a product that has been molded and is ready for production, the specific parameters are as follows: Downstream surface 131 includes a first slope, a second slope, and a third slope. The angle between the first and second slopes is 210°, and the angle between the second and third slopes is 205°. The width of the first slope is 20mm, the width of the second slope is 115mm, and the length of the third slope is 170mm. The distance between the third slope of one downstream surface 131 and the first downstream surface of another adjacent downstream surface 131 can be 151mm.

[0052] The distance between the bottom end of the drain ditch 132 and the bottom end of the frame 11 can be 20 mm. The drain 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 end 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 40 mm, the width of the first side surface is 70 mm, and the width of the second side surface is 15 mm. It should be noted that the above angles are all top surface angles. The distance between the second side surface of one drain board 130 and the second downstream surface of another adjacent drain board 130 can be 153 mm, and the distance between the second side surface of one drain board 130 and the third downstream surface of another adjacent drain board 130 can be 150 mm.

[0053] After repeated verification by technical personnel, this size and angle can provide maximum protection against rain and snow, and the test results are better.

[0054] 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 plate 120. The rainwater falling on the waterproof plate 120 can only flow downward along the waterproof plate 120, and the rainwater falling on the dense mesh plate 121 will be broken up and fall into the drainage layer 13 through the mesh; the broken up rainwater flows downward along the downstream surface 131 of the drainage plate 130 until it flows into the drainage ditch 132 and is discharged to both ends.

[0055] The above steps can be increased, decreased, modified, or the order can be adjusted as needed.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
