Description

Technical Field

[0001] This application relates to the technical field of blinds, and particularly to a blind, a building, a box body, and an electronic device. Background Art

[0002] As a ventilation device, the blind is widely used in the fields of buildings, outdoor electronic devices, etc. due to its simple structure and flexible layout. However, although the blinds in the related art can achieve the ventilation effect, they still have deficiencies in rain protection and water ingress prevention. Summary of the Utility Model

[0003] The main technical problem to be solved by this application is to provide a blind, a building, a box body, and an electronic device with better rain protection effect.

[0004] To solve the above technical problem, in a first aspect, a technical solution adopted by this application is to provide a blind, including:

[0005] A frame having a top wall and a bottom wall along a first direction, and a first side wall and a second side wall spaced apart along a second direction;

[0006] A plurality of first blades and a plurality of second blades, clamped between the top wall and the bottom wall; the lengths of the first blades and the second blades extend along the first direction;

[0007] Wherein, the plurality of first blades and the plurality of second blades are alternately and spaced apart in sequence along the second direction, adjacent first blades and second blades partially overlap in a third direction, and the first blades are bent towards the second blades, and the second blades are bent towards the first blades, so as to form a swirl area in the overlapping area; the first direction and the second direction intersect, and the third direction is perpendicular to the first direction and the second direction;

[0008] Both ends of the first blade are bent towards the second blade to form an arc or a part of a regular polygon, and the second blade is bent towards the first blade to form an arc or a part of a regular polygon, wherein the number of sides of the regular polygon is greater than or equal to 6.

[0009] In the above technical solution, by using the structure in which the first blade and the second blade are bent towards the opposite side, and the arrangement in which the plurality of first blades and the plurality of second blades are alternately and spaced apart in sequence along the second direction and adjacent first blades and second blades partially overlap in the third direction, the airflow can be guided to form a swirl when passing through the first blade and the second blade. By using the effect of the swirl, the water droplets in the airflow can be discharged. Therefore, the blind provided by this application can have a better rain protection effect while achieving the ventilation effect.

[0010] In some of these embodiments, both ends of the first blade are bent towards the second blade to form half of a regular polygon, and the second blade is bent towards the first blade to form half of a regular polygon.

[0011] In the above technical solution, by bending both ends of the first blade towards the second blade to form half of a regular polygon, and bending the second blade towards the first blade to form half of a regular polygon, the overlapping area of the first blade and the second blade can be defined by a surface similar to a semi-circle, which is beneficial to the formation of a swirling flow area.

[0012] In some of these embodiments, the bottom wall has a plurality of drain holes.

[0013] In the above technical solution, by providing a plurality of drain holes in the bottom wall, it is beneficial to smoothly drain the separated water droplets / water flow, reduce the accumulation of water droplets / water flow on the bottom wall, and also reduce the entry of water droplets / water flow into the window.

[0014] In some of these embodiments, along the first direction, the drain holes are provided corresponding to the swirling flow area, and the ratio of the area of the drain holes to the area of the swirling flow area is greater than or equal to 50% and less than 100%.

[0015] In the above technical solution, by arranging the drain holes corresponding to the swirling flow area, that is, the drain holes are provided directly below the swirling flow area, it can just dock the falling water droplets / water flow, reducing the impact of the water droplets / water flow on the bottom wall; since the ratio of the area of the drain holes to the area of the swirling flow area is greater than or equal to 50% and less than 100%, the outflow speed of the water droplets / water flow through the drain holes can be further increased, thereby reducing the situation of water accumulation.

[0016] In some of these embodiments, the ratio of the area of the drain holes to the area of the swirling flow area is 70%-80%.

[0017] In the above technical solution, since the ratio of the area of the drain holes to the area of the swirling flow area is 70%-80%, within this range, it can drain water quickly and will not affect the strength of the bottom wall due to the overly large drain holes.

[0018] In some of these embodiments, the shutter further includes:

[0019] A seat body, disposed on the side of the bottom wall away from the top wall; a first surface of the seat body close to the bottom wall is connected to the bottom wall to form a drainage groove, and the angle between the first surface and the bottom wall is an acute angle.

[0020] In the above technical solution, the seat body can direct the water droplets discharged from the drain holes to a predetermined discharge path. The first surface can utilize gravity to guide the water flow so that it can be quickly discharged instead of accumulating on the seat body, which can reduce the situation where the already successfully separated moisture re-mixes into the processed air, improving the dryness of the gas finally delivered indoors. At the same time, the cooperation between the seat body and the drain holes can also help maintain the cleanliness inside the device, reducing corrosion or other potential problems caused by water accumulation.

[0021] In some of the embodiments, the seat body is a wedge-shaped structure, and a second surface of the seat body away from the bottom wall is parallel to the bottom wall.

[0022] In the above technical solution, since the seat body is a wedge-shaped structure and the second surface of the seat body away from the bottom wall is parallel to the bottom wall, on the one hand, it is beneficial to the installation and fixation of the louvers, and on the other hand, it is beneficial to install the top wall and the bottom wall on a building or device that requires ventilation and rain protection in a predetermined direction.

[0023] In some of the embodiments, the seat body has a plurality of grooves, and the plurality of grooves are formed on the first surface; the plurality of grooves are arranged in one-to-one correspondence with the plurality of drain holes; a projection of the drain holes along the first direction is located within the corresponding grooves.

[0024] In the above technical solution, since the plurality of grooves and the plurality of drain holes are arranged in one-to-one correspondence, the water droplets / water flow flowing out of the drain holes can enter the corresponding grooves. Therefore, the grooves provide a more definite flow path, which can guide the water droplets / water flow to flow along the grooves and the direction of the first surface, and can guide the water droplets / water flow to a specific position for discharge or collection, reducing the accumulation of water droplets / water flow flowing around and causing other adverse effects.

[0025] In some of the embodiments, the drain holes are located in a central region of a projection of the swirl region along the first direction to the bottom wall.

[0026] In the above technical solution, the drain holes are located in the central region of the projection of the swirl region along the first direction to the bottom wall, which can combine water efficiency and the stability of the overall structure.

[0027] In some of the embodiments, the drain holes include a first sub-drain hole and a second sub-drain hole; the first sub-drain hole is arranged close to the first blade, and the second sub-drain hole is arranged close to the second blade; the position of the second sub-drain hole is higher than the position of the first sub-drain hole, or, the bottom wall has a plurality of stoppers, and each stopper is arranged on a side of the second sub-drain hole away from the second blade.

[0028] In the above technical solution, when the water volume is too large, since the position of the second sub-drainage hole is higher than that of the first sub-drainage hole, or the stopper is arranged on the side of the second sub-drainage hole away from the second blade, the possibility of rainwater flowing into the window can be reduced.

[0029] To solve the above technical problem, in a second aspect, another technical solution adopted by the present application is to provide a building, including:

[0030] a wall; and

[0031] a shutter, arranged on the wall;

[0032] wherein, the shutter is the shutter provided in any of the above embodiments, and the first direction is the vertical direction of the wall.

[0033] In the above technical solution, by using the structure in which the first blade and the second blade are bent towards the opposite side, and the arrangement in which a plurality of first blades and a plurality of second blades are sequentially staggered and spaced along the second direction and adjacent first blades and second blades partially overlap in the third direction, a swirling flow can be formed when the air flow passes through the first blade and the second blade. By using the effect of the swirling flow, the water droplets in the air flow can be discharged. Therefore, the shutter provided by the present application can have a better rain-proof effect while achieving the ventilation effect.

[0034] In some of the embodiments, the first surface slopes downward towards the side away from the wall.

[0035] In the above technical solution, since the first surface slopes downward towards the side away from the wall, the water flow discharged through the first surface will flow outside the building.

[0036] To solve the above technical problem, in a third aspect, another technical solution adopted by the present application is to provide a box body, including:

[0037] a side wall; and

[0038] a shutter, arranged on the side wall;

[0039] wherein, the shutter is the shutter provided in any of the above embodiments, and the first direction is the vertical direction of the side wall.

[0040] In the above technical solution, by using the structure in which the first blade and the second blade are bent towards the opposite side, and the arrangement in which a plurality of first blades and a plurality of second blades are sequentially staggered and spaced along the second direction and adjacent first blades and second blades partially overlap in the third direction, a swirling flow can be formed when the air flow passes through the first blade and the second blade. By using the effect of the swirling flow, the water droplets in the air flow can be discharged. Therefore, the shutter provided by the present application can have a better rain-proof effect while achieving the ventilation effect.

[0041] In some of these embodiments, the first surface slopes downward toward the side away from the side wall.

[0042] In the above technical solution, since the first surface slopes downward toward the side away from the side wall, the water flow discharged through the first surface will flow outside the box.

[0043] To solve the above technical problems, in a fourth aspect, another technical solution adopted by this application is to provide an electronic device, including:

[0044] Electrical components and the box body provided in the third aspect of the above embodiments, and the electrical components are arranged inside the box body.

[0045] In the above embodiments, by using the structure in which the first blade and the second blade are bent toward the opposite side, and the arrangement in which a plurality of first blades and a plurality of second blades are alternately arranged in sequence along the second direction with intervals and adjacent first blades and second blades partially overlap in the third direction, the airflow can be guided to form a swirl when passing through the first blade and the second blade. By using the effect of the swirl, the water droplets in the airflow can be discharged. Therefore, the louver provided by this application can have a better rainproof effect while achieving the ventilation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] As a ventilation device, the shutter is widely used in the fields of architecture, outdoor electronic devices, such as billboards, etc. due to its advantages of simple structure and flexible layout. However, although the existing shutters can achieve the ventilation effect, they still have deficiencies in rain shielding and water ingress prevention.

[0069] For example, in heavy rain weather, the gaps between adjacent louver blades make it difficult for the shutter to effectively block rainwater, and still some rainwater will enter the internal space through the gaps between the louver blades, resulting in the dampness, mildew and even damage of the side walls, and increasing the working load of the dehumidification equipment.

[0070] To solve the problem of insufficient rain shielding and water ingress prevention described above, an embodiment of the present application provides a louver, which includes a frame, a plurality of first blades, and a plurality of second blades; the frame has a top wall and a bottom wall along a first direction, and a first side wall and a second side wall spaced apart along a second direction; the plurality of first blades and the plurality of second blades are clamped between the top wall and the bottom wall; the lengths of the first blades and the second blades extend along the first direction; wherein, the plurality of first blades and the plurality of second blades are alternately and spaced apart in sequence along the second direction, adjacent first blades and second blades partially overlap in a third direction, and the first blades are bent towards the second blades, and the second blades are bent towards the first blades, thereby forming a swirling flow area in the overlapping area; the first direction and the second direction intersect, and the third direction is perpendicular to the first direction and the second direction; both ends of the first blade are bent towards the second blade to form an arc or a part of a regular polygon, and the second blade is bent towards the first blade to form an arc or a part of a regular polygon, wherein the number of sides of the regular polygon is greater than or equal to 6.

[0071] In this embodiment, by using the structure in which the first blades and the second blades are bent towards the opposite sides, and the arrangement in which the plurality of first blades and the plurality of second blades are alternately and spaced apart in sequence along the second direction and adjacent first blades and second blades partially overlap in the third direction, the airflow can be guided to form a swirling flow when passing through the first blades and the second blades. By using the effect of the swirling flow, the water droplets in the airflow can be discharged. Therefore, the louver provided by the present application can have a better rain shielding effect while achieving the ventilation effect.

[0072] The present application will be described in detail below with reference to the drawings and embodiments.

[0073] Please refer to Figures 1 - 3 , Figure 1 which is a perspective structural view of a louver 100 provided by some embodiments of the present application; Figure 2 is Figure 1 a front view of the louver 100 in Figure 3 and is a schematic diagram of a swirling flow formed between the first blade 20 and the second blade 30.

[0074] The louver 100 in the embodiments of the present application includes a frame 10, a plurality of first blades 20 and a plurality of second blades 30; the frame 10 has a top wall 11 and a bottom wall 12 along a first direction, and a first side wall 13 and a second side wall 14 spaced apart along a second direction; the plurality of first blades 20 and the plurality of second blades 30 are clamped between the top wall 11 and the bottom wall 12; the lengths of the first blades 20 and the second blades 30 extend along the first direction; wherein, the plurality of first blades 20 and the plurality of second blades 30 are sequentially staggered and spaced along the second direction, adjacent first blades 20 and second blades 30 partially overlap in a third direction, and the first blades 20 are bent towards the second blades 30, and the second blades 30 are bent towards the first blades 20, so as to form a vortex region 40 in the overlapping region; the first direction and the second direction intersect, and the third direction is perpendicular to the first direction and the second direction. Both ends of the first blade 20 are bent towards the second blade 30 to form an arc or a part of a regular polygon, and the second blade 30 is bent towards the first blade 20 to form an arc or a part of a regular polygon, wherein the number of sides of the regular polygon is greater than or equal to 6.

[0075] Wherein, the frame 10 is a supporting structure of the louver 100, which is used to fix the first blades 20 and the second blades 30 and play a role in connecting external components (such as the wall of a building). In some embodiments, the material of the frame 10 can be metal, wood or plastic. Among them, the metal frame 10 is durable and not easy to deform; the wooden frame 10 is more decorative; the plastic frame 10 has good weather resistance and wear resistance, is not easy to get damp, and has a lower cost.

[0076] Furthermore, the frame 10 has a top wall 11 and a bottom wall 12 along the first direction, and a first side wall 13 and a second side wall 14 spaced apart along the second direction. Among them, the first direction is the vertical direction when the louver 100 is in normal use, that is Figure 1 the Z direction in Figure 1 and the second direction is the horizontal direction when the louver 100 is in normal use, that is

[0077] The first blade 20 and the second blade 30 are sheet-like bodies with a certain strength, which are used to realize the ventilation function and also have the function of blocking sunlight or rain. A plurality of first blades 20 and a plurality of second blades 30 are clamped between the top wall 11 and the bottom wall 12. The lengths of the first blades 20 and the second blades 30 extend along the first direction. The two ends of the blades (including the first blades 20 and the second blades 30) are respectively installed on the top wall 11 and the bottom wall 12. Therefore, the first blades 20 and the second blades 30 are installed vertically. For example, a plurality of installation grooves (not shown in the figure) are provided on the bottom surface of the top wall 11 and the top surface of the bottom wall 12, and the two ends of the blades are inserted into the installation grooves. Alternatively, the two ends of the blades can also be fixed to the top wall 11 and the bottom wall 12 by bonding or welding.

[0078] Further, in some embodiments, a plurality of first blades 20 and a plurality of second blades 30 are arranged alternately and at intervals along the second direction. A gap 60 is formed between adjacent first blades 20, and a gap 60 is also formed between adjacent second blades 30, which facilitates the ventilation inside and outside the shutter 100. In addition, adjacent first blades 20 and second blades 30 partially overlap in the third direction, and the first blade 20 bends towards the second blade 30, and the second blade 30 bends towards the first blade 20, so as to form a swirl region 40 in the overlapping region. Wherein, the third direction is perpendicular to the first direction and the second direction, that is Figure 1 the Y direction in. The swirl region 40 is a fluid channel, which is respectively communicated with the gaps 60 on both sides, and can guide the air flow to form a swirl in the overlapping region. As Figure 3 shown, the external air flow enters from the gap 60 between adjacent second blades 30, and enters the interior from the gap 60 between adjacent first blades 20 after passing through the swirl region 40. Figure 3 As shown by the hollow arrow in, when the shutter 100 is actually applied, for example, applied to the building field, the direction of the air flow from the outside to the inside of the building.

[0079] Among them, swirl is a rotational motion, which can increase the turbulence in the air flow, thereby helping to separate water droplets from the air flow. Under the action of the swirl, larger water droplets are more likely to deviate from the original air flow path due to inertia and move towards the periphery, and finally fall onto the bottom wall 12 of the shutter 100 due to gravity. At the same time, smaller water droplets may also aggregate into larger water droplets due to collision, and then are also easily affected by gravity and sink. Therefore, the embodiments of the present application can greatly reduce the raindrops from entering the room or other devices where the shutter 100 is installed.

[0080] In this embodiment, a swirling flow region 40 is formed by using the structure in which the first blades 20 and the second blades 30 are bent toward the opposite side, and the arrangement in which a plurality of first blades 20 and a plurality of second blades 30 are alternately arranged in sequence along the second direction with intervals therebetween and the adjacent first blades 20 and second blades 30 partially overlap in the third direction. The swirling flow region 40 can guide the air flow to form a swirl when passing through the first blades 20 and the second blades 30. By using the effect of the swirl, the water droplets in the air flow are discharged. Therefore, the louver 100 provided in the present application can have a better rain-proof effect while achieving the ventilation effect. By bending both ends of the first blade 20 toward the second blade 30 to form an arc or a part of a regular polygon, and bending the second blade 30 toward the first blade 20 to form an arc or a part of a regular polygon, and the number of sides of the regular polygon is greater than or equal to 6, the overlapping region of the first blade 20 and the second blade 30 can be defined by two arc-shaped or similar arc-shaped surfaces, which is beneficial to the formation of the swirling flow region 40.

[0081] Optionally, in some embodiments, both ends of the first blade 20 are bent toward the second blade 30 to form an arc or a part of a regular polygon, and the second blade 30 is bent toward the first blade 20 to form an arc or a part of a regular polygon.

[0082] Please refer to Figure 4 and Figure 5 , wherein, Figure 4 is a top view of the louver 100 provided in some embodiments of the present application; Figure 5 is a top view of the louver 100 provided in some other embodiments of the present application.

[0083] Both ends of the first blade 20 are bent toward the second blade 30 to form an arc (as shown in Figure 4 ) or a part of a regular polygon (as shown in Figure 5 ). The arc or the part of the regular polygon can make the line smoother. The regular polygon can be a regular hexagon, a regular heptagon, a regular octagon, a regular nonagon, a regular decagon, a regular hendecagon or a regular dodecagon. The part of the regular polygon can be half or more than half of the regular polygon, but cannot be closed. For example, when the regular polygon is an hendecagon, the part of the regular polygon can be the part composed of six consecutive sides. The more sides the regular polygon has, the closer the part of the regular polygon is to a semi-circle. When the air flow encounters an inclined or curved surface, due to the hydrodynamic effect, the air flow will be forced to change direction and flow along the surface of the blades (including the first blades 20 and the second blades 30). Since the blades are designed as an arc or a part of a regular polygon, and there is a gap 60 between adjacent blades, then when the air flow passes through the gap 60, a lateral force will be generated, prompting the air flow to deflect in a specific direction. As more air flow joins this circular path, a swirl is formed.

[0084] The principle of this application using swirl to improve the dehydration efficiency of the system is as follows: The swirl increases the turbulence intensity inside the air flow, causing the water droplets that were originally evenly distributed in the air flow to start experiencing complex changes in their movement trajectories, promoting the separation of water droplets from the air. For larger water droplets, they have a higher inertial mass, so it is more difficult for them to change their movement directions following the rapid turning of the air flow. In a swirling environment, larger water droplets tend to maintain their original paths, gradually deviate from the main flow channel, and move towards the periphery of the swirl. As the distance from the center increases, these large water droplets will eventually fall to the bottom due to gravity. For smaller water droplets, although they are also affected by the swirl, due to their smaller volume and lighter mass, they are more likely to rotate with the air flow. However, in the swirl, even the smallest water droplets are difficult to completely avoid colliding with other particles. When two or more small water droplets collide, they may merge into a larger water droplet. This aggregation effect helps to accelerate the growth process of water droplets, enabling even the initially very tiny droplets to quickly grow to a size large enough to be captured by gravity. In addition, as the swirl continues to act, more and more small water droplets continuously gather and grow, further enhancing the dehydration efficiency of the entire system.

[0085] Optionally, both ends of the first blade 20 are bent towards the second blade 30 to form half of a regular polygon, and both ends of the second blade 30 are bent towards the first blade 20 to form half of a regular polygon. In this embodiment, by bending both ends of the first blade 20 towards the second blade 30 to form half of a regular polygon, and bending the second blade 30 towards the first blade 20 to form half of a regular polygon, the overlapping area of the first blade 20 and the second blade 30 can be defined by a surface similar to a semi - circle, which is beneficial for forming the swirl region 40.

[0086] Furthermore, in some embodiments, the bottom wall 12 has a plurality of drain holes 120.

[0087] The drain holes 120 are used to drain the water droplets / water flows that drip due to gravity. The shape of the drain holes 120 can be circular, oval, or strip - shaped. In this embodiment of the application, the case where the shape of the drain holes 120 is circular is taken as an example for introduction. In this embodiment, by providing a plurality of drain holes 120 on the bottom wall 12, it is beneficial to smoothly drain the separated water droplets / water flows, reduce the accumulation of water droplets / water flows on the bottom wall 12, and also reduce the entry of water droplets / water flows into the window.

[0088] It can be understood that by providing an inclined surface or a drain groove on the top surface of the bottom wall 12, the water droplets / water flows on the bottom wall 12 can also be drained. By providing the drain holes 120, the water droplets / water flows on the bottom wall 12 can be drained to the bottom first and then discharged to the outside.

[0089] Optionally, in some embodiments, along the first direction, the drain hole 120 is disposed corresponding to the swirl region 40, and the ratio of the area of the drain hole 120 to the area of the swirl region 40 is greater than or equal to 50% and less than 100%.

[0090] The area of the drain hole 120 affects the discharge speed of water droplets / water flow. Especially for heavy rain weather, a higher discharge speed of water droplets / water flow is very important. Specifically, along the first direction, the drain hole 120 is disposed corresponding to the swirl region 40. Therefore, the drain hole 120 is disposed directly below the swirl region 40, exactly docking the falling water droplets / water flow, and reducing the impact of the water droplets / water flow on the bottom wall 12. The area of the drain hole 120 refers to the cross-sectional area of the hole of the drain hole 120, and the area of the swirl region 40 refers to the projected area in the first direction of the region where the air flow forms a rotational flow in the overlapping region between a first blade 20 and an adjacent second blade 30. The ratio of the area of the drain hole 120 to the area of the swirl region 40 is greater than or equal to 50% and less than 100%, and can be, for example, 50%, 60%, 70%, 80% or 90%, etc.

[0091] In this embodiment, by disposing the drain hole 120 corresponding to the swirl region 40, that is, the drain hole 120 is disposed directly below the swirl region 40, exactly docking the falling water droplets / water flow, and reducing the impact of the water droplets / water flow on the bottom wall 12; since the ratio of the area of the drain hole 120 to the area of the swirl region 40 is greater than or equal to 50% and less than 100%, the outflow speed of the water droplets / water flow through the drain hole 120 can be further increased, thereby reducing the accumulation of water.

[0092] Further, in some embodiments, the ratio of the area of the drain hole 120 to the area of the swirl region 40 is 70% - 80%.

[0093] Specifically, in some specific embodiments, the ratio of the area of the drain hole 120 to the area of the swirl region 40 can be 70%, 72%, 75%, 77% or 80%, etc.

[0094] In this embodiment, since the ratio of the area of the drain hole 120 to the area of the swirl region 40 is 70% - 80%, within this range, it can drain water quickly and will not affect the strength of the bottom wall 12 due to the overly large drain hole 120.

[0095] Further, please continue to refer to Figure 1 and Figure 2 , in some embodiments, the shutter 100 further includes a seat body 50; the seat body 50 is disposed on the side of the bottom wall 12 away from the top wall 11; the first surface 51 of the seat body 50 close to the bottom wall 12 is connected to the bottom wall 12 to form a drainage groove, and the included angle between the first surface 51 and the bottom wall 12 is an acute angle.

[0096] The seat body 50 is a structure that can receive the water droplets / water flow discharged from the drain holes 120 and guide the water droplets / water flow to be discharged in a predetermined direction. The seat body 50 is arranged on the side of the bottom wall 12 away from the top wall 11 (i.e., when the louver 100 is in use, the seat body 50 is arranged below the bottom wall 12), so as to be able to receive the water droplets / water flow discharged from the drain holes 120. Further, the seat body 50 has a first surface 51, and the included angle between the first surface 51 and the bottom wall 12 can be an acute angle. The first surface 51 is connected to the bottom wall 12 to form a drain groove. The setting of the acute angle can accelerate the drainage speed and guide the water flow to the specified drainage direction (such as draining to the outdoor side), improving the drainage efficiency. The material of the seat body 50 can be plastic, rubber or metal material.

[0097] In this embodiment, the setting of the seat body 50 can direct the water droplets discharged from the drain holes 120 to a predetermined discharge path. The first surface 51 can utilize gravity to guide the water flow so that it can be quickly discharged instead of accumulating on the seat body 50, which can reduce the situation that the successfully separated moisture re-mixes into the processed air, improving the dryness of the gas finally delivered indoors; at the same time, the cooperation between the seat body 50 and the drain holes 120 can also help maintain the cleanliness inside the device and reduce corrosion or other potential problems caused by water accumulation.

[0098] Optionally, in some embodiments, the seat body 50 is a wedge-shaped structure, and the second surface 52 of the seat body 50 away from the bottom wall 12 is parallel to the bottom wall 12.

[0099] The seat body 50 is a wedge-shaped structure, and the second surface 52 of the seat body 50 away from the bottom wall 12 is parallel to the bottom wall 12. Therefore, when installing the louver 100, on the one hand, it is beneficial to the installation and fixation of the louver 100, and on the other hand, it is beneficial to install the top wall 11 and the bottom wall 12 in a predetermined direction on a building or device that requires ventilation and has a rain protection requirement.

[0100] Optionally, please refer to Figure 6 , Figure 6 which is a schematic structural diagram of the seat body 50 provided in some other embodiments of the present application.

[0101] In some embodiments, the seat body 50 has a plurality of grooves 53, and the plurality of grooves 53 are opened on the first surface 51; the plurality of grooves 53 are arranged in one-to-one correspondence with the plurality of drain holes 120; the projection of the drain holes 120 along the first direction is located in the corresponding grooves 53.

[0102] The depth direction of the groove 53 is perpendicular to the first surface 51, and the groove 53 is recessed into the interior of the seat body 50. The groove 53 can make the water droplets / water flow that fall onto the seat body 50 through the drain hole 120 flow away in a regular predetermined direction. The predetermined direction is the extending direction of the length of the groove 53. The number of the grooves 53 is multiple. In some embodiments, the number of the grooves 53 is the same as the number of the drain holes 120. The multiple grooves 53 and the multiple drain holes 120 are arranged in one-to-one correspondence. The projection of the drain hole 120 along the first direction is located within the corresponding groove 53, so that each groove 53 correspondingly receives the water droplets / water flow flowing out of one drain hole 120.

[0103] In this embodiment, since the multiple grooves 53 and the multiple drain holes 120 are arranged in one-to-one correspondence, the water droplets / water flow flowing out of the drain hole 120 can enter the corresponding groove 53. Therefore, the groove 53 provides a more definite flow path to guide the water droplets / water flow to flow along the direction of the groove 53 and the first surface 51, and can guide the water droplets / water flow to a specific position for discharge or collection, reducing the accumulation of water or other adverse effects caused by the water droplets / water flow flowing around.

[0104] Further, please continue to refer to Figure 1 and Figure 3 , in some embodiments, the drain hole 120 is located in the central region of the projection of the swirl area 40 along the first direction onto the bottom wall 12.

[0105] The position of the drain hole 120 is also an important factor affecting the discharge speed of the water droplets / water flow. When the water-containing air enters the swirl state, the water droplets gather towards the center of the swirl under the action of the air swirl and then fall under the action of gravity. Therefore, the drain hole 120 is located in the central region of the projection of the swirl area 40 along the first direction ( Figure 1 and Figure 3 the Z direction in

[0106] onto the bottom wall 12), that is, the drain hole 120 is arranged directly below the middle of the corresponding swirl area 40, which can improve the drainage efficiency. In addition, the central region is a position where the structure is more uniformly stressed. Arranging the drain hole 120 here can reduce the problem of structural stress concentration caused by the improper position of the drain hole 120, thereby improving the stability of the overall structure.

[0107] In this embodiment, the drain hole 120 is located in the central region of the projection of the swirl area 40 along the first direction onto the bottom wall 12, which can achieve both water efficiency and the stability of the overall structure.

[0107] Optionally, please refer to Figure 7 and Figure 8 , Figure 7 is a top view of the louver 100 provided in some other embodiments of the present application; Figure 8 is Figure 7Cross-sectional view of the louver 100 along line VIII-VIII in [].

[0108] In some other embodiments, the drain hole 120 includes a first sub-drain hole 121 and a second sub-drain hole 122; the first sub-drain hole 121 is disposed close to the first blade 20, and the second sub-drain hole 122 is disposed close to the second blade 30; the position of the second sub-drain hole 122 is higher than the position of the first sub-drain hole 121, or the bottom wall 12 has a plurality of stoppers 123, and each stopper 123 is disposed on the side of the second sub-drain hole 122 away from the second blade 30.

[0109] Wherein, a plurality of first sub-drain holes 121 are arranged along the second direction ( Figure 7 X direction in []), and the centers of the plurality of first sub-drain holes 121 are arranged approximately in a straight line; a plurality of second sub-drain holes 122 are arranged along the second direction, and the centers of the plurality of second sub-drain holes 122 are arranged approximately in a straight line. The water droplets / water flow falling from the swirling region 40 flow towards the first sub-drain hole 121 and the second sub-drain hole 122. The first sub-drain hole 121 may be located at the position of the gap 60 between adjacent second blades 30, and the second sub-drain hole 122 may be located at the position of the gap 60 between adjacent first blades 20.

[0110] In some embodiments, when the louver 100 is installed and used, the first blade 20 is close to the interior, and the second blade 30 is located on the side of the first blade 20 away from the interior. At this time, when the water droplets / water flow flow towards the second sub-drain hole 122, it may further flow into the gap 60 between the adjacent first blades 20, and then there is a risk of flowing into the interior. Therefore, in this embodiment, the position of the second sub-drain hole 122 is higher than the position of the first sub-drain hole 121, or the bottom wall 12 has a plurality of stoppers 123, and each stopper 123 is disposed on the side of the second sub-drain hole 122 away from the second blade 30. Wherein, the position of the second sub-drain hole 122 being higher than the position of the first sub-drain hole 121 means that the port of the second sub-drain hole 122 located on the top surface of the bottom wall 12 is higher than the port of the first sub-drain hole 121 located on the top surface of the bottom wall 12, that is, the top surface of the bottom wall 12 in the region between the second sub-drain hole 122 and the first sub-drain hole 121 (including the swirling region 40) is an inclined surface. On the one hand, it makes the water droplets falling from the swirling region 40 easier to flow towards the first sub-drain hole 121; on the other hand, when the rainfall is too large, during the process of the water droplets falling from the swirling region 40 flowing towards the first sub-drain hole 121, they will also be discharged through the first sub-drain hole 121 and are not easily introduced into the window. The length of the stopper 123 is greater than or equal to the distance between two adjacent first blades 20, that is, the length of the stopper 123 is greater than or equal to the width of the gap 60; the height of the stopper 123 is less than the height of the blades (including the first blade 20 and the second blade 30), so that it will neither affect ventilation and air exchange nor reduce the inflow of rainwater.

[0111] In this embodiment, when the water volume is too large, since the position of the second sub-drainage hole 122 is higher than that of the first sub-drainage hole 121, or the stopper 123 is arranged on the side of the second sub-drainage hole 122 away from the second blade 30, the possibility of rainwater flowing into the window can be reduced.

[0112] The louver 100 disclosed in the embodiment of the present application can be used in fields that require frequent ventilation and have requirements for rain prevention and waterproofing, such as buildings, vehicles, billboards, air conditioners, electric cabinets, greenhouse sheds, or industrial machinery, etc. The building can be, but is not limited to, the outer walls of residential houses, offices / conference rooms, store windows / show areas, etc. The vehicle can include, but is not limited to, cars, ships, etc.

[0113] Please refer to Figure 9 and Figure 10 For this, some embodiments of the present application provide a building 1000, including a wall body 200 and a louver 100; the louver 100 is arranged on the wall body 200; wherein, the louver 100 is the louver 100 provided in any of the above embodiments, and the first direction is the vertical direction of the wall body 200.

[0114] The wall body 200 is an enclosure structure of the building, which plays a role in supporting and separating spaces, and at the same time provides a fixed foundation for the installation of the louver 100. The vertical direction of the wall body 200 serves as the first direction of the louver 100, providing a positioning and direction reference for the installation and use of the louver 100. Further, since the lengths of the first blade 20 and the second blade 30 extend along the first direction, the first blade 20 and the second blade 30 are vertically arranged. Figure 10 The direction of the hollow arrow in the figure is the direction of the air flow from the outside to the inside of the room.

[0115] Further, in some embodiments, the first surface 51 is inclined downward toward the side away from the wall body 200.

[0116] The first surface 51 is inclined downward toward the side away from the wall body 200. Therefore, there is a certain inclination angle between the first surface 51 and the wall body 200, and the first surface 51 gradually descends from the side close to the wall body 200 to the side away from the wall body 200.

[0117] In this embodiment, since the first surface 51 is inclined toward the side away from the wall body 200, the water flow discharged through the first surface 51 will flow outside the building.

[0118] Please refer to Figure 11, some embodiments of the present application provide a box body 2000, including a side wall 300 and a louver 100, and the louver 100 is arranged on the side wall 300; wherein, the louver 100 is the louver 100 provided by any of the above embodiments, and the first direction is the vertical direction of the side wall 300.

[0119] Among them, the box body 2000 is a structure with a certain space. In different application scenarios, the shape, size, and material of the box body 2000 will be designed and selected according to specific requirements. In some embodiments, the box body 2000 can be the box body 2000 of an advertising board or the box body 2000 of an electrical cabinet. The side wall 300 is an important part of the box body 2000, forming the side boundary of the box body 2000, which can play a supporting role and jointly form a complete enclosed space with other parts of the box body 2000 (such as the top plate, bottom plate, etc.). The side wall 300 of the box body 2000 is the installation foundation of the louver 100, providing a fixed support surface for the louver 100. Figure 11 The direction of the hollow arrow is the direction of the airflow from outside the box to inside the box.

[0120] In some embodiments, the first surface 51 slopes downward toward the side away from the side wall 300.

[0121] The first surface 51 slopes downward toward the side away from the side wall 300. Therefore, there is a certain inclination angle between the first surface 51 and the side wall 300, and the first surface 51 gradually descends from the side close to the side wall 300 to the side away from the side wall 300.

[0122] In the above embodiment, in this embodiment, since the first surface 51 slopes downward toward the side away from the side wall 300, the water flow discharged through the first surface 51 will flow outside the box body 2000.

[0123] Further, please refer to Figure 12 , some embodiments of the present application provide an electronic device 1, including electrical components 3000 and the box body 2000 provided by the above embodiment, and the electrical components 3000 are arranged inside the box body 2000.

[0124] Among them, the electronic device 1 can be an electronic device that requires ventilation and heat dissipation and has requirements for rain and waterproofing, such as an advertising board, an electrical cabinet, etc. The electrical components will be different for different electronic devices. For example, in an advertising board, the electrical components can include: lamp tubes, power modules, switches, etc.; in an electrical cabinet, the electrical components can include: circuit breakers, relays, indicator lights, current transformers, and voltage transformers, etc. There are usually multiple battery units in the electrical cabinet.
