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.

[0040] In the first aspect, the present application embodiment provides a shutter device 100, please refer to Figure 1 The shutter device 100 includes a box body 10 and a shutter assembly 20.

[0041] For the above-mentioned box 10, please refer to Figures 1 to 3The box 10 is a container or shell for containing, protecting and fixing other objects. The box 10 encloses an installation space 11, and the box 10 can provide physical protection for objects in the installation space 11 to 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 installation space 11 is an area or space for installation and operation of a specific system, component or structure to ensure that the specific system, component or structure can operate normally. The box 10 is provided with a first opening 111 and a second opening 112 that are connected to the installation space 11. The sizes of the first opening 111 and the second opening 112 are approximately the same. The first opening 111 and the second opening 112 are relatively arranged along the first direction X, which can be used for air intake and exhaust, so as to facilitate the flow of air inside the box 10 to achieve a good ventilation effect.

[0042] 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 enclose the box body 10. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0043] For the above shutter assembly 20, please refer to Figures 4 to 6 The shutter assembly 20 is arranged in the installation space 11. The shutter assembly 20 includes a plurality of shutter units 21 arranged in a second direction Y. The number of the shutter units 21 is determined according to the size of the installation space 11, and the installation space 11 is filled as much as possible. A gap is preset between two adjacent shutter units 21 to form a ventilation duct 22, and the ventilation duct 22 connects the first opening 111 and the second opening 112. As the number of shutter units 21 increases, the number of ventilation ducts 22 formed increases, and the plurality of ventilation ducts 22 facilitates the air to flow between the first opening 111, the ventilation duct 22 and the second opening 112, thereby enhancing the ventilation effect of the shutter device 100.

[0044] For further information, please refer to Figure 5 and Figure 6The louver unit 21 includes a first blade 211, a second blade 212 and a connecting member 213. The first blade 211 and the second blade 212 are respectively arranged at positions close to the first opening 111 and the second opening 112. The first blade 211 and the second blade 212 are distributed in different planes and connected by the connecting member 213. Specifically, the first blade 211 is arranged at a position close to the first opening 111. Along the second direction Y, the first blade 211 can form a certain inclination angle with the first opening 111. A plurality of first blades 211 are arranged in an array at the first opening 111. When rainwater or a water column contacts the first blade 211, water flow entering the installation space 11 can be reduced, thereby improving the waterproof performance of the louver device 100. The second blade 212 is arranged at a position close to the second opening 112. Along the second direction Y, the second blade 212 can form a certain inclination angle with the second opening 112. Multiple second blades 212 are arranged in the second opening 112. When rainwater or water columns come into contact with the second blades 212, the water flow entering the installation space 11 can be reduced, thereby improving the waterproof performance of the shutter device 100.

[0045] Observe along the first direction X, please refer to Figure 5 and Figure 6 The first blade 211 and the second blade 212 are distributed in different planes and are connected by a connecting piece 213. The first blade 211, the connecting piece 213 and the second blade 212 assemble the ventilation duct 22 structure into a labyrinth air duct. Compared with the straight air duct of the traditional design, the ventilation duct 22 of the embodiment of the present application can effectively reduce the entry of dust, impurities, water, etc. into the ventilation duct 22, further improve the waterproof level of the shutter device 100, and can also reduce the transmission of airflow noise.

[0046] In some embodiments, please refer to Figure 6 The first blade 211 includes a first end 2111 close to the first opening 111 and a second end 2112 far from the first opening 111, and the second blade 212 includes a third end 2121 close to the first opening 111 and a fourth end 2122 far from the first opening 111. The first end 2111 and the third end 2121 are far from the arrangement start end 23 of the plurality of louver units 21, the second end 2112 and the fourth end 2122 are close to the arrangement start end 23, and the connecting member 213 is connected between the second end 2112 and the third end 2121.

[0047] In the embodiment of the present application, the shutter device 100 can be installed on the ventilation device, and the direction of the wind discharged by the ventilation device 100 in the shutter device 100 is as follows: Figure 4 and Figure 5The wind discharged from the ventilation device first passes through the first opening 111 and enters the ventilation passage 22 in the plurality of louver units 21, then enters the second opening 112 from the ventilation passage 22, and is discharged from the second opening 112. Figure 6 and Figure 7 The wind passes through the first opening 111, flows along the first blade 211 to the second end 2112, flows along the connecting piece 213 to the third end 2121, flows along the second blade 212 to the fourth end 2122, and finally is discharged from the second opening 112. The ventilation duct 22 formed above is shaped like a labyrinth duct, which not only has a good ventilation effect, but also improves the waterproof level of the shutter device 100.

[0048] The embodiment of the present application provides a shutter device 100, comprising a housing 10 and a shutter assembly 20. The shutter assembly 20 comprises a plurality of shutter units 21 arranged along a second direction Y, a gap is preset between two adjacent shutter units 21 to form a ventilation duct 22, and the ventilation duct 22 connects the first opening 111 and the second opening 112, so as to facilitate the airflow to flow between the first opening 111, the ventilation duct 22 and the second opening 112. As the number of shutter units 21 increases, the number of ventilation ducts 22 formed increases, and while ensuring the waterproof performance of the shutter device 100, the ventilation effect of the shutter device 100 is improved. The second blade 212 is arranged at a position close to the second opening 112, and along the second direction Y, the first blade 211 can form a certain inclination angle with the first opening 111, and the plurality of first blades 211 are arranged in an array at the first opening 111, and when rainwater or water column contacts the first blade 211, it can reduce the water flow entering the installation space 11, thereby improving the waterproof performance of the shutter device 100. The first blade 211 and the second blade 212 are distributed in different planes and are connected by a connecting piece 213. The first blade 211, the connecting piece 213 and the second blade 212 assemble the ventilation duct 22 structure into a maze air duct. Compared with the straight air duct of the traditional design, the ventilation duct 22 of the embodiment of the present application can effectively reduce the entry of dust, impurities, water, etc. into the ventilation duct 22, further improve the waterproof level of the shutter device 100, and can also reduce the transmission of airflow noise.

[0049] In some embodiments, please refer to Figure 5 and Figure 7 The ventilation duct 22 includes an air inlet 211 and an air outlet 222, wherein the air inlet 221 is close to the first opening 111 and is tilted downwardly distributed, and the air outlet 222 is close to the second opening 112 and is tilted upwardly distributed. The first opening 111 is connected to the air inlet 221, and the second opening 112 is connected to the air outlet. The air inlet 221 is close to the first opening 111 and is tilted downwardly distributed, and the air outlet 222 is close to the second opening 112 and is tilted upwardly distributed, which can reduce dust, dirt and other impurities from entering the ventilation duct 22 and keep the ventilation duct 22 clean.

[0050] In some embodiments, please refer to Figures 5 to 7 , the connecting member 213 is connected between the first blade 211 and the second blade 212, the first blade 211 and the second blade 212 are arranged parallel to each other, and the angles between the connecting member 213 and the first blade 211 and the second blade 212 are acute angles, so that the flow path of air in the ventilation duct 22 is increased, and the short circuit between the air inlet 221 and the air outlet 222 is reduced, which is conducive to better guiding the air flow and reducing the problem of uneven air flow or local poor air flow. Further, when observed along the first direction X, the projections of the two adjacent first blades 211 partially overlap, and the projection of the second end 2112 falls on the projection of the second blade 212. When observed in the opposite direction of the first direction X, the projection of the third end 2121 falls on the projection of the first blade 211, so that the contact between the adjacent louver units 21 is closer. In particular, an effective shielding can be formed between the adjacent first blades 211, which can prevent moisture, dust, impurities, etc. from entering the ventilation duct 22. The function between adjacent second blades 212 is equivalent to that between adjacent first blades 211 .

[0051] In some embodiments, please refer to Figure 2 and Figure 8 The shutter device 100 further includes a first baffle 50, which is fixedly connected to the box body 10 at the first opening 111 along the second direction Y. The first baffle 50 blocks the first blade 211 of the shutter unit 21 at the arrangement start end 23 along the second direction Y. When the shutter assembly 20 is placed in the installation space 11, since the first blade 211 at the arrangement start end 23 is far away from the first side portion 12 of the box body 10 and the gap is large, water, impurities, etc. can easily enter the shutter assembly 20 through the first opening 111, or enter other equipment through the first opening 111. The first baffle 50 effectively blocks the gap between the first blade 211 and the first side portion 12, thereby enhancing the dustproof and waterproof effects of the shutter device 100.

[0052] In some embodiments, please refer to Figure 3 , Figure 8 and Fig. 9, the shutter device 100 also includes a dustproof component 30, which is arranged at the second opening 112. The dustproof component 30 is mainly used to protect the shutter component 20, reduce dust, particulate matter, impurities, etc. from entering the shutter device 100, thereby protecting the normal operation of the shutter device 100 and extending the service life. Further, the dustproof component 30 includes a dustproof net 31 and a mounting frame 32. The dustproof net 31 is a mesh used to control the diffusion of dust and particulate matter. The material of the dustproof net 31 can be a metal steel wire, or it can be a sponge mesh structure made of polyethylene, polyurethane or polyester. The mounting frame 32 is a frame or structure used to fix, support or protect the dustproof net 31. The mounting frame 32 can be made of metal, plastic, etc. The mounting frame 32 is arranged at the second opening 112 and connected to the box body 10, and the dustproof net 31 is installed on the mounting frame 32 at the second opening 112. The mounting frame 32 can provide a stable foundation for the dustproof net 31 , so that the dustproof net 31 can be firmly fixed on the box body 10 , and can reduce the damage to the dustproof net 31 caused by external factors.

[0053] In some embodiments, please refer to Figure 8 and Fig. 9 The mounting frame 32 includes a first mounting member 321 and a second mounting member 322 that are relatively arranged along the second direction Y, and the mounting frame 32 also includes a first support member 323, and the first support member 323 is connected between the first mounting member 321 and the second mounting member 322. Further, the mounting frame 32 also includes a third mounting member 324 and a fourth mounting member 325 that are relatively arranged along the third direction Z, and the third mounting member 324 and the fourth mounting member 325 are respectively connected between the first mounting member 321 and the second mounting member 322, and the mounting frame 32 also includes a second support member 326, and the second support member 326 is connected between the third mounting member 324 and the fourth mounting member 325. The first support member 323 and the second support member 326 can provide additional support and fixation to the mounting frame 32, reduce deformation or loosening of the mounting frame 32 during use, and shake when subjected to external force or vibration, and improve the stability and safety of the structure.

[0054] In some embodiments, please refer to Figure 2 and Figure 8 The shutter device 100 further includes a waterproof member 40, which is disposed on the end surface of the box body 10 away from the second opening 112, and the waterproof member 40 is disposed around the first opening 111. For example, when the shutter device 100 is installed on a ventilation device, the waterproof member 40 can effectively reduce the amount of liquid such as water entering the ventilation device from the gap between the first opening 111 and the ventilation device, and also improve the air tightness between the shutter device 100 and the ventilation device. For example, the waterproof member 40 can be a waterproof rubber strip.

[0055] In some embodiments, please refer to Figure 2 and Figure 6 , along the third direction Z, the two ends of the first blade 211 are respectively connected with a first fixing portion 214 and a second fixing portion (not shown in the figure), the first fixing portion 214 is fixedly connected to the first wall portion 14, and the second fixing portion is fixedly connected to the second wall portion 15, so that the first blade 211 is fixed to the box body 10.
