[0031] See also Figures 1 to 4 The embodiment of the utility model provides a drainage structure of a system louver, which includes: a frame 1, the frame 1 has two first openings 3 and a second opening 4 in opposite directions; louvers 2, a plurality of louvers 2 are vertically arranged in the frame 1, the top and bottom edges of the louvers 2 are respectively connected to the upper and lower sides of the frame 1, the plurality of louvers 2 are parallel, and a diversion cavity 5 is formed between adjacent louvers 2, and the openings at both ends of the diversion cavity 5 are respectively connected to the first opening 3 and the second opening 4; wherein the louvers 2 include: a first louver 21 and a second louver 22, one side of the first louver 21 faces the first opening 3, the other side of the first louver 21 is connected to one side of the second louver 22, one side of the second louver 22 faces the second opening 4, the other side of the second louver 22 faces the first opening 3, and a water retaining groove 6 with a notch facing the first opening 3 is formed between the other side of the first louver 21 and the other side of the second louver 22. Optionally, in other embodiments, the louver 2 can also be horizontally arranged in the frame 1, and the two ends of the louver 2 are respectively connected to the left and right sides of the frame 1.

[0032] It is understandable that when the shutter system of this embodiment is assembled, the first opening 3 is generally oriented toward the outdoors and the second opening 4 is oriented toward the indoors. The air communication between the first opening 3 and the second opening 4 can be achieved through the guide cavity 5 formed between the plurality of shutter blades 2, that is, the air communication between the indoor and outdoor areas. When it rains outside the first opening 3, the rainwater will first be blocked by the first shutter blade 21 after entering the first opening 3, and after being blocked by the first shutter blade 21, it will slide down along the first shutter blade 21 to the lower frame 12 of the frame 1 and then flow to the outdoors through the first opening 3; or, it will flow along the wall surface of the first shutter blade 21 toward the second opening 4, flow to the connection between the first shutter blade 21 and the second shutter blade 22, that is, the water retaining groove 6, and after being blocked by the water retaining groove 6, it will slide down to the lower frame 12 of the frame 1 and then flow to the outdoors through the first opening 3.

[0033] Furthermore, the first louver 21 includes: a first louver 21 body, and a first curved portion 211 and a second curved portion 212 arranged on the first louver 21 body, the first curved portion 211 is close to the first opening 3, the second curved portion 212 is close to the second opening 4, the cross-sections of the first curved portion 211 and the second curved portion 212 are both arc-shaped, the first louver 21 body has a front and back side, the arc centers of the first curved portion 211 and the second curved portion 212 are respectively located on both sides of the front and back sides of the first louver 21 body, so that the first louver 21 body has a change of direction at the connection between the first curved portion 211 and the second curved portion 212.

[0034] It should be emphasized that all the louvers 2 installed in the frame 1 are parallel and have the same posture. In this embodiment, the first louver 21 is a rainwater blocking structure, and the design of the first curved portion 211 and the second curved portion 212 makes the first louver 21 more resistant to pressure and makes the louver system more stable. It is also a supporting structure for the frame 1. In this embodiment, the design of the first curved portion 211 and the second curved portion 212 has the function of blocking rainwater from entering and supporting the frame 1. The cross-sections of the first curved portion 211 and the second curved portion 212 are both arc-shaped. This design prevents rainwater from directly passing through the guide cavity 5 between the louvers 2, but instead produces water droplets on the curved surface, thereby reducing the possibility of rainwater entering the room. Furthermore, the arc centers of the first curved portion 211 and the second curved portion 212 are respectively located on the front and back sides of the first louver 21 body. This design allows rainwater to form a vortex effect on the surface of the blades, thereby increasing the time that rainwater stays on the surface of the blades and slowing down the speed at which rainwater flows into the room. In addition, there is a change of direction at the connection between the first curved portion 211 and the second curved portion 212, which also increases the difficulty of rainwater entering the room through the blades, effectively preventing the penetration of rainwater. Preferably, the center of the first curved portion 211 is toward the right frame 14 of the frame 1, and the center of the second curved portion 212 is toward the left frame 13 of the frame 1. At the same time, from the first opening 3 toward the second opening 4, the first louver 21 is inclined toward the right frame 14 of the frame 1, that is, the other side of the first louver 21 is closer to the right frame 14 of the frame 1 than the one side of the first louver 21.

[0035] Preferably, the projection of the other side of the first louver 21 toward the surface where the first opening 3 is located overlaps with the projection of the adjacent first louver 21 toward the surface where the first opening 3 is located. Preferably, the projection of the other side of the first louver 21 toward the surface where the first opening 3 is located overlaps with the projection of the adjacent first louver 21 near the right frame 14 of the frame 1. This design can form a tighter shielding structure through the overlapping projections of adjacent first louvers 21, reducing the direct entry of rainwater, and due to the overlapping projections of adjacent first louvers 21, the coverage area of ​​the blades for rainwater is actually increased, making it more difficult for rainwater to directly pass through the blades into the room, thereby improving the waterproof effect.

[0036] Further, the second louver blade 22 includes: a second louver blade 22 body, and a third curved portion 221 and a fourth curved portion 222 arranged on the second louver blade 22 body, the third curved portion 221 is close to the first opening 3, the fourth curved portion 222 is close to the second opening 4, the cross-sections of the third curved portion 221 and the fourth curved portion 222 are both arc-shaped, the louver blade 2 has a front and a back side, and the arc centers of the fourth curved portion 222 and the first curved portion 211 are both located on the front side or the back side of the louver blade 2. Among them, the second curved portion 212 guides the incoming rainwater, and the water retaining groove 6 formed between the third curved portion 221 and the second curved portion 212 blocks the rainwater. Furthermore, the arc centers of the fourth arc portion 222 and the first arc portion 211 are located on the same side of the louver 2, and the first arc portion 211, the second arc portion 212 and the fourth arc portion 222 are connected to form a roughly S-shape, which not only improves the water-blocking performance, but also improves the supporting capacity of the louver 2 for the frame 1.

[0037] Specifically, the arc centers of the fourth curved portion 222 and the third curved portion 221 are respectively located on both sides of the front and back sides of the louver 2, and the arc centers of the third curved portion 221 and the second curved portion 212 are both located on the front side or the back side of the louver 2. Preferably, the arc center of the first curved portion 211 faces the right frame 14 of the frame 1, the arc center of the second curved portion 212 faces the left frame 13 of the frame 1, the arc center of the third curved portion 221 faces the left frame 13 of the frame 1, and the arc center of the fourth curved portion 222 faces the right frame 14 of the frame 1. At the same time, from the first opening 3 to the second opening 4, the second louver 22 is inclined toward the left frame 13 of the frame 1, that is, one side of the second louver 22 is closer to the left frame 13 of the frame 1 than the other side of the second louver 22.

[0038] Specifically, the frame 1 includes: an upper frame 11, a lower frame 12, a left frame 13, and a right frame 14. The edge height of the lower frame 12 near the second opening 4 is higher than the edge height of the lower frame 12 near the first opening 3, so that rainwater entering through the first opening 3 and blocked by the louver 2 cannot enter the room through the second opening 4 after falling on the lower frame 12, thereby ensuring the waterproof performance of the louver system. Optionally, the edge of the lower frame 12 near the second opening 4 is provided with a lower baffle 121 facing the upper frame 11, and when rainwater tries to pass through the second opening 4, it will be blocked by the first baffle and cannot pass through. Optionally, an upper baffle 111 is provided on the edge of the upper frame 11 near the second opening 4 and faces the lower frame 12, a left baffle 131 is provided on the edge of the left frame 13 near the second opening 4 and faces the right frame 14, and a right baffle 141 is provided on the edge of the right frame 14 near the second opening 4 and faces the left frame 13. The upper baffle 111, the lower baffle 121, the left baffle 131 and the right baffle 141 prevent rainwater entering the frame 1 through the first opening 3 from flowing into the room through the second opening 4 via the walls of the upper frame 11, the lower frame 12, the left frame 13 and the right frame 14.

[0039] Furthermore, a first extension plate 213 is provided on one side of the first louver 21, facing the left frame 13 or the right frame 14 of the frame 1, and a first inner hook 214 is provided on one side of the first extension plate 213 away from the first louver 21, facing the second opening 4. Preferably, the first extension plates 213 on all first louvers 21 are arranged facing the left frame 13. The presence of the first extension plate 213 and the first inner hook 214 strengthens the strength of the louver 2, reduces the shaking and deformation of the louver 2 in windy and rainy weather, maintains a good protective effect, and forms a stable louver 2 system, so that it can better withstand the influence of adverse weather conditions such as external wind and rain, and prolongs its service life.

[0040] Furthermore, one side edge of the second louver 22 is provided with a second extension plate 223 facing the left frame 13 and the right frame 14 of the frame 1 respectively, and the second extension plate 223 is also provided with a second inner hook 224 facing the first opening 3 on one side edge away from the second louver 22. The second extension plate 223 also strengthens the strength of the louver 2, reduces the shaking and deformation of the louver 2 in windy and rainy weather, and maintains a good protective effect. At the same time, a water-blocking groove is formed by the second louver 22, the second extension plate 223, and the second inner hook 224, which can once again block the rainwater entering the guide cavity 5 and about to pass through the guide cavity 5, thereby enhancing the rainproof and water-proof performance of the louver system.

[0041] Further, the louver blades 2 are connected to the upper frame 11 and the lower frame 12 of the frame 1 by screws. Further, the upper frame 11 is connected to the left frame 13 and the right frame 14 by screws, and the lower frame 12 is connected to the left frame 13 and the right frame 14 by screws.

[0042] Specifically, the louver 2 is provided with at least two connecting grooves 7 for screws to pass through, one of the connecting grooves 7 is provided on the first louver 21, and the other is provided on the second louver 22 and is located at the connection between the first louver 21 and the second louver 22. Optionally, the connection between the first louver 21 and the second louver 22 is the intersection of the third curved portion 221 and the fourth curved portion 222.

[0043] Specifically, the left frame 13 is provided with at least two left connecting grooves 7 for screws to pass through, and the right frame 14 is provided with at least two right connecting grooves 7 for screws to pass through. The screws are upwardly connected to the left connecting groove 7 of the left frame 13 through the lower frame 12, upwardly connected to the right connecting groove 7 of the right frame 14 through the lower frame 12, and upwardly connected to the connecting groove 7 of the louver 2 through the lower frame 12; the screws are also downwardly connected to the left connecting groove 7 of the left frame 13 through the upper frame 11, downwardly connected to the right connecting groove 7 of the right frame 14 through the upper frame 11, and downwardly connected to the connecting groove 7 of the louver 2 through the upper frame 11.

[0044] Compared with the prior art, the drainage structure of the system louvers of the utility model can smoothly realize the interconnection between the first opening and the second opening to achieve ventilation through the guide cavity formed between a number of louver blades, and can smoothly block the fluid entering from the first opening through the water retaining groove formed between the first louver blades and the second louver blades, thereby improving the rainproof and water-proof performance of the louver system.

[0045] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto.
