[0041] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. In addition, the technical features involved in the different embodiments of the present application described below may be combined with each other as long as they do not conflict with each other.

[0042] In the first aspect, the present application embodiment provides a shutter device 100, please refer to Figure 1 The device includes a box body 10 and a shutter module 20.

[0043] For the above-mentioned box 10, please refer to Figure 2 and Figure 3 The box 10 is a container or shell for containing, protecting and fixing other objects. The box 10 encloses an installation space 11. The box 10 can provide physical protection for objects in the installation space 11 and reduce collision, damage or erosion with external objects. In addition, the box 10 can effectively prevent dust, rain or other debris from entering the installation space 11, and keep the installation space 11 clean. The box 10 is provided with a first opening 111 and a second opening 112 that are in communication with the installation space 11. The first opening 111 and the second opening 112 are arranged relatively along the first direction X. The first opening 111 is slightly larger than the second opening 112. The more wind enters from the first opening 111, the faster it flows out from the second opening 112, which can speed up the airflow inside the box 10 to achieve a good ventilation effect.

[0044] For further information, please refer to Figure 2 and Figure 3 Along the second direction Y, the box body 10 includes a first side portion 12 and a second side portion 13 that are oppositely disposed. Along the third direction Z, the box body 10 includes a first wall portion 14 and a second wall portion 15 that are oppositely disposed. The first side portion 12 and the second side portion 13 are respectively disposed between the first wall portion 14 and the second wall portion 15. The first wall portion 14, the first side portion 12, the second wall portion 15 and the second side portion 13 are jointly enclosed to form the box body 10. Among them, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0045] For the above-mentioned shutter module 20, please refer to Figure 4 and Figure 5 , multiple louver modules 20 are arranged in the installation space 11 along the second direction Y, and the number of louver modules 20 can be determined according to the size of the installation space 11, so that the louver modules 20 can fill the installation space 11 as much as possible. Each louver module 20 can be disassembled, taken out or installed separately, so that the louver module 20 is convenient for maintenance, replacement or cleaning, and the flexibility and convenience of the use of the louver device 100 are improved. In addition, the louver module 20 is modularized to facilitate the expansion and reconfiguration of the louver device 100. During the manufacturing and transportation process, each louver module 20 can be manufactured and transported separately, which shortens the manufacturing time and reduces the production cost. Among them, a gap is preset between two adjacent louver modules 20 to form a ventilation duct 30, and the ventilation duct 30 is arranged between the first opening 111 and the second opening 112. As the number of louver modules 20 increases, the number of ventilation ducts 30 formed increases, and multiple ventilation ducts 30 facilitate air circulation between the first opening 111 and the second opening 112, thereby enhancing the ventilation effect of the louver device 100.

[0046] For further information, please refer to Figure 4 and Figure 5 The louver module 20 includes a first louver assembly 21 and a second louver assembly 22. The first louver assembly 21 is arranged near the first opening 111, and the second louver assembly 22 is arranged near the second opening 112. A plurality of first louver assemblies 21 and second louver assemblies 22 can be arranged at intervals along the second direction Y. A gap is preset between two adjacent first louver assemblies 21 to form a first ventilation duct 31, and a gap is preset between two adjacent second louver assemblies 22 to form a second ventilation duct 32. The ventilation duct 30 includes a first ventilation duct 31 and a second ventilation duct 32 that are connected. The first louver assembly 21 and the second louver assembly 22 can be removed or installed separately, making the louver module 20 more convenient to repair, replace or clean, further improving the flexibility and convenience of the louver device 100.

[0047] The embodiment of the present application provides a shutter device 100, including a box body 10 and a shutter module 20. A plurality of shutter modules 20 are arranged in the installation space 11 along the second direction Y. Each shutter module 20 can be individually disassembled, taken out or installed, so that the shutter module 20 is convenient for maintenance, replacement or cleaning, and the flexibility and convenience of the use of the shutter device 100 are improved. In addition, the shutter module 20 is modularized to facilitate the expansion and reconfiguration of the shutter device 100. During the manufacturing and transportation process, each shutter module 20 can be manufactured and transported separately, which shortens the manufacturing time and reduces the production cost. Among them, a gap is preset between two adjacent shutter modules 20 to form a ventilation duct 30, and the ventilation duct 30 is arranged between the first opening 111 and the second opening 112. As the number of shutter modules 20 increases, the number of ventilation ducts 30 formed increases, and multiple ventilation ducts 30 facilitate air circulation between the first opening 111 and the second opening 112, thereby enhancing the ventilation effect of the shutter device 100.

[0048] In some embodiments, please refer to Figures 4 to 6 The first louver assembly 21 includes a first blade 211, a second blade 212 and a first connecting member 213, and the first connecting member 213 is connected between the first blade 211 and the second blade 212. The first blade 211 is close to the first opening 111 and is bent downward, and the second blade 212 is away from the first opening 111 and is bent upward. A gap is preset between two adjacent first louver assemblies 21 to form a first ventilation channel 31. Along the second direction Y, the first blade 211 can partially block the portion of the first ventilation channel 31 facing the first opening 111. When rainwater or water column contacts the first blade 211, it can reduce the water flow entering the first ventilation channel 31. The second blade 212 can partially block the portion of the first ventilation channel 31 that is connected to the second ventilation channel 32, reduce rainwater from entering the second ventilation channel 32, and improve the overall waterproof performance of the louver device 100.

[0049] For further information, please refer to Figures 4 to 6 The second louver assembly 22 includes a third blade 221, a fourth blade 222 and a second connecting member 223, and the second connecting member 223 is connected between the third blade 221 and the fourth blade 222. The third blade 221 is away from the second opening 112 and is bent downward, and the fourth blade 222 is close to the second opening 112 and is bent upward. Along the second direction Y, the fourth blade 222 can partially block the portion of the second ventilation passage 32 facing the second opening 112, and when rainwater or water column contacts the fourth blade 222, it can reduce the flow of water into the second ventilation passage 32. The third blade 221 can partially block the portion of the first ventilation passage 31 that is connected to the second ventilation passage 32, reduce rainwater from entering the second ventilation passage 32, and improve the overall waterproof performance of the louver device 100.

[0050] In some embodiments, please refer to Figures 4 to 6, when observed along the first direction X, in two adjacent first louver assemblies 21, the projection of the first blade 211 of one first louver assembly 21 partially overlaps with the projection of the second blade 212 of the other first louver assembly 21. Or, the projection of the first blade 211 of one first louver assembly 21 does not overlap with the projection of the second blade 212 of the other first louver assembly 21. The first blade 211, the first connecting member 213 and the second blade 212 form the structure of the first ventilation duct 31 into a labyrinth duct similar to an "S" shape. Compared with the linear duct of the traditional design, the first ventilation duct 31 of the embodiment of the present application can effectively reduce the dust, impurities, water, etc. from entering the first ventilation duct 31, which can not only improve the waterproof level of the louver device 100, but also reduce the transmission of airflow noise.

[0051] Please refer to Figure 7 The figure shows a structure of two adjacent first louver assemblies 21 arranged along the second direction Y. The two first louver assemblies 21 are respectively recorded as the first louver assembly 21a and the first louver assembly 21b. The figure also shows the flow direction of wind in the first ventilation duct 31. One of the first louver assemblies 21a includes a first blade 211a, a second blade 212a and a first connecting member 213a, and the other first louver assembly 21b includes a first blade 211b, a second blade 212b and a first connecting member 213b. A first air duct space 311 is formed between the second blade 212a and the first blade 211b.

[0052] The figure also shows a structure of two adjacent second louver assemblies 22 arranged along the second direction Y. The two second louver assemblies 22 are respectively recorded as the second louver assembly 22a and the second louver assembly 22b. The figure also shows the flow direction of wind in the second ventilation duct 32. One of the second louver assemblies 22a includes a third blade 221a, a fourth blade 222a and a second connecting member 223a, and the other second louver assembly 22b includes a third blade 221b, a fourth blade 222b and a second connecting member 223b. A second air duct space 321 is formed between the fourth blade 222b and the third blade 221a.

[0053] The wind enters the first ventilation duct 31 through the first opening 111, flows upward along the first connecting piece 213a, and then enters the first air duct space 311 after being blocked by the second blade 212a. The wind continues to flow upward and enters the second ventilation duct 32 along the first connecting piece 213b, flows upward along the second connecting piece 223a, and then enters the second air duct space 321 after being blocked by the fourth blade 222a. The wind continues to flow upward and flows out from the second opening 112 along the second connecting piece 223b, thus forming a double "S"-shaped labyrinth air duct.

[0054] In some embodiments, the first louver assembly 21 and the second louver assembly 22 may be staggered in the first direction X. Figure 8 The second blade 212 and the third blade 221 are detachably connected. For example, the second blade 212 and the third blade 221 are fixed by screws, so that the first ventilation duct 31 and the second ventilation duct 32 are directly connected, which shortens the size of the installation space 11 and speeds up the airflow. In addition, the second blade 212 and the third blade 221 are detachably connected, which enhances the installation flexibility between the first louver assembly 21 and the second louver assembly 22, making the louver module 20 more stable and reducing looseness caused by collision and vibration.

[0055] In some embodiments, please refer to Fig. 9 There is a first gap space 113 between the second blade 212 and the third blade 221. Along the second direction Y, the airflow entering the first ventilation channel 31 can flow out through at least one second ventilation channel 32. The provision of the first gap space 113 increases the flow path of the airflow, speeds up the outflow of the gas, and makes the ventilation effect of the shutter device 100 better.

[0056] In some embodiments, please refer to Figure 4 , Figure 7 and Fig.10 The first blade 211 includes a first main body 2111 and a first extension 2112, and the first main body 2111 is connected between the first connecting member 213 and the first extension 2112. Along the first direction X, the first main body 2111 is arranged close to the first opening 111, and the first extension 2112 is bent in a direction away from the first opening 111. When the first blade 211 contacts rainwater or a water column, the first main body 2111 and the first extension 2112 can block the water flow entering the first ventilation passage 31 from the first opening 111, and the first extension 2112 can guide the water flow to fall into the first connecting member 213 of the adjacent first louver assembly 21, so that the water flow flows out of the first opening 111 along the first connecting member 213, so as to reduce the water flow entering the installation space 11.

[0057] For further information, please refer to Figure 4 , Figure 7 and Fig.10The second blade 212 includes a second main body 2121 and a second extension 2122, and the second main body 2121 is connected between the first connecting member 213 and the second extension 2122. Along the first direction X, the second main body 2121 is arranged away from the first opening 111, and the second extension 2122 is bent toward the first opening 111. The second blade 212 is arranged between the first ventilation channel 31 and the second ventilation channel 32. The second main body 2121 and the second extension 2122 can perform secondary shielding on the water flow entering from the first opening 111, reduce the water flow entering the installation space 11, and further improve the waterproof performance of the shutter device 100.

[0058] In some embodiments, please refer to Figure 4 , Figure 7 and Fig.11 The third blade 221 includes a third main body 2211 and a third extension 2212, and the third main body 2211 is connected between the second connecting member 223 and the third extension 2212. Along the first direction X, the third main body 2211 is arranged away from the second opening 112, and the third extension 2212 is bent toward the second opening 112. The third main body 2211 and the third extension 2212 are also arranged between the first ventilation channel 31 and the second ventilation channel 32, and the third extension 2212 is bent toward the second opening 112 to block the water entering from the first ventilation channel 31, and the third extension 2212 can guide the water flow to fall into the adjacent second connecting member 223, and the water can flow out of the first opening 111 through the guidance of the second connecting member 223.

[0059] For further information, please refer to Figure 4 , Figure 7 and Fig.11 The fourth blade 222 includes a fourth main body 2221 and a fourth extension 2222. The fourth main body 2221 is connected between the second connecting member 223 and the fourth extension 2222. Along the first direction X, the fourth main body 2221 is arranged close to the second opening 112, and the fourth extension 2222 is bent in a direction away from the second opening 112. The fourth main body 2221 and the fourth extension 2222 are arranged at the air outlet of the second ventilation passage 32, which can block the moisture entering the second ventilation passage 32 from the first ventilation passage 31. The moisture can flow out of the first opening 111 along the fourth extension 2222 and the second connecting member 223, thereby improving the overall waterproof performance of the shutter device 100.

[0060] In some embodiments, please refer to Figure 8 , Fig.10 and Fig.11, the second main body 2121 of the second blade 212 is detachably connected to the third main body 2211 of the third blade 221. For example, the second main body 2121 and the third main body 2211 are fixed by screws. Along the first direction X, the first ventilation duct 31 and the second ventilation duct 32 are directly connected, which shortens the size of the installation space 11 and speeds up the airflow. In addition, the second main body 2121 and the third main body 2211 are closely connected, which enhances the stability of the first louver assembly 21 and the second louver assembly 22 and reduces the looseness caused by collision and vibration.

[0061] In some embodiments, please refer to Fig. 9 , Fig.10 and Fig.11 The second main body 2121 of the second blade 212 and the third main body 2211 of the third blade 221 are provided with a first gap space 113. Along the second direction Y, the airflow entering the first ventilation channel 31 can flow out through at least one second ventilation channel 32. The provision of the first gap space 113 increases the flow path of the airflow, speeds up the outflow of the gas, and makes the ventilation effect of the shutter device 100 better.

[0062] In some embodiments, please refer to Fig.12 The louver device 100 also includes a filter assembly 40, which is mainly used to filter dust, particulate matter and impurities in the outside air to reduce these substances from entering the louver device 100, thereby protecting the normal operation of the louver device 100 and extending its service life. Further, the filter assembly 40 includes filter cotton 41 and a mounting member 42. The filter cotton 41 is a material used to filter air or liquid, usually made of fiber or non-woven fabric. The main function is to reduce dust, particulate matter and other impurities from entering the louver device 100, thereby ensuring the normal operation of the system and improving its work efficiency.

[0063] The mounting member 42 is a frame or structure for fixing, supporting or protecting the filter cotton 41. The mounting member 42 can be made of metal, plastic or the like. The mounting member 42 is arranged at the second opening 112 and connected to the housing 10, and the filter cotton 41 is mounted on the mounting member 42 at the second opening 112. The mounting member 42 can provide a stable foundation for the filter cotton 41, so that the filter assembly 40 can be firmly fixed on the housing 10, and can reduce the damage to the filter cotton 41 caused by external factors. Captive screws are also arranged on the mounting member 42. In particular, if the filter cotton 41 needs to be replaced, it is only necessary to loosen the captive screws, remove the filter assembly 40 and replace the filter cotton 41, and then fix the replaced filter assembly 40 to the housing 10 through the captive screws.

[0064] In some embodiments, please refer to Figure 4 and Fig.12The shutter device 100 further includes a waterproof member 50, which is disposed on a side of the housing 10 away from the filter assembly 40, and is disposed around the first opening 111.
