[0002] In areas with more dust and sand, the air is mixed with a large amount of solid or non-aqueous particles such as dust, sand grains, and grit, that is, the air is mixed with angular atmospheric dust particles. In the prior art, when outdoor fresh air is supplemented indoors through a window structure (when indoor and outdoor air convection occurs), atmospheric dust particles often enter the room along with the air flow.

[0054] In areas with a lot of sand and dust, the air is mixed with a large amount of dust, sand, gravel and other solid or non-aqueous particles, that is, the air is mixed with atmospheric dust particles with angles; currently, when the outdoor fresh air is added to the room through the window structure (when the indoor and outdoor air are convective), the atmospheric dust particles tend to enter the room with the airflow, and when the airflow speed decreases, the atmospheric dust particles will separate from the air and settle down, and then accumulate and pollute the indoor space. Based on the technical problem that when the window structure is used to add outdoor fresh air to the room in areas with a lot of sand and dust, the present invention provides a shutter structure and a shutter system, the shutter structure includes a frame, a first sand baffle mechanism and a second sand baffle mechanism; the frame is connected to the outer peripheral surface and connected to the wall, the first sand baffle mechanism and the second sand baffle mechanism are installed on the inner peripheral surface of the frame, the first sand baffle mechanism is arranged at the air inlet end face, the second sand baffle mechanism is arranged at the air outlet end face, and a plurality of first sand baffles are arranged at equal intervals on the first sand baffle mechanism, and a plurality of first sand baffles are arranged at equal intervals on the second sand baffle mechanism. The sand barrier mechanism is provided with a plurality of second sand barriers at equal intervals, and at the same time controls the first sand barriers and the second sand barriers to be staggered and alternately arranged; thereby, when the air enters the room through the louver structure, it first passes between the second sand barriers, and then is blocked by the first sand barriers, passes between the first sand barriers and the second sand barriers, and finally enters the room through the gap between two adjacent first sand barriers. In this process, the air flow velocity is blocked and reduced, thereby causing the atmospheric dust particles and water droplets therein to settle and separate from the air, thereby effectively preventing the atmospheric dust particles and water droplets from entering the room. For details, please refer to the following embodiments.

[0055] Please refer to Figures 1 to 9 In a first embodiment of the present invention, a shutter structure 10 is provided, which includes a frame 11, a first sand shield mechanism 12, and a second sand shield mechanism 13; the frame 11 includes an air inlet end face 111 and an air outlet end face 112 at both ends along the thickness direction. It can be understood that the thickness direction is the thickness direction of the frame 11 and is the same as the air inlet direction. When the shutter structure 10 is used to supplement outdoor fresh air to the room, the air first enters the first and second sand shield mechanisms 12 and 13 through the air inlet end face 111, and then enters the room through the air outlet end face 112; the first sand shield mechanism 12 is arranged at the air inlet end face 111, including a plurality of first sand shields 14 arranged at equal intervals; the second sand shield mechanism 13 is arranged at the air outlet end face 112, including a plurality of second sand shields 15 arranged at equal intervals; the first sand shield 14 and the second sand shield 15 are staggered and alternately arranged to block atmospheric dust particles and water droplets.

[0056] It can be understood that the frame 11 is connected to the wall on the outer peripheral surface, and the first sand baffle mechanism 12 and the second sand baffle mechanism 13 are installed on the inner peripheral surface of the frame 11. The first sand baffle mechanism 12 is arranged at the air inlet end face 111, and the second sand baffle mechanism 13 is arranged at the air outlet end face 112. A plurality of first sand baffles 14 are arranged at equal intervals in the first sand baffle mechanism 12, and a plurality of second sand baffles 15 are arranged at equal intervals in the second sand baffle mechanism 13. At the same time, the first sand baffles 14 and the second sand baffles 15 are controlled to be arranged in a staggered and alternating manner. Thus, when the air enters the room through the louver structure 10, it first passes through between the second sand baffles 15, then is blocked by the first sand baffles 14 and passes through between the first sand baffles 14 and the second sand baffles 15, and finally enters the room through the gap between two adjacent first sand baffles 14. During this process, the air flow velocity is blocked and reduced, so that the atmospheric dust particles and water droplets in it settle and separate from the air, thus effectively preventing the atmospheric dust particles and water droplets from entering the room.

[0057] In some preferred embodiments, the interval between adjacent first sand baffles 14 is set as the air inlet 16, and the interval between adjacent second sand baffles 15 is set as the air outlet 17. The air inlets 16 and the air outlets 17 are arranged in a staggered and alternating manner. It can be seen that when the air enters the room through the louver structure 10, it first enters through the air inlets 16 between the second sand baffles 15, then is blocked by the first sand baffles 14 and passes through between the first sand baffles 14 and the second sand baffles 15, and finally enters the room through the air outlets 17 between two adjacent first sand baffles 14. During this process, the air flow velocity is blocked and reduced, so that the atmospheric dust particles and water droplets in it settle and separate from the air, thus effectively preventing the atmospheric dust particles and water droplets from entering the room.

[0058] Furthermore, the first sand baffle 14 and two adjacent second sand baffles 15 are arranged in a triangular shape, and the second sand baffle 15 and two adjacent first sand baffles 14 are arranged in a triangular shape. It can be understood that the first sand baffle 14 is arranged on the perpendicular bisector of two adjacent second sand baffles 15, and the second sand baffle 15 is arranged on the perpendicular bisector of two adjacent first sand baffles 14. Thus, the air flow entering the room is effectively blocked and diverted, and the flow velocity of the air flow is effectively reduced, ensuring that the atmospheric dust particles and water droplets settle and separate from the air, thus effectively preventing the atmospheric dust particles and water droplets from entering the room.

[0059] In some other preferred embodiments, the first sand guard plate 14 and the second sand guard plate 15 are arranged in a U shape, and the first sand guard plate 14 is provided with a first opening 141, and the second sand guard plate 15 is provided with a second opening 151; the first opening 141 faces the air outlet end face 112, and the second opening 151 faces the air inlet end face 111. It can be understood that the second opening 151 of the second sand guard plate 15 faces the air inlet direction. That is to say, after the outdoor air enters through the air inlet 16, it enters the second opening 151, is blocked and decelerated by the second opening 151, so that the atmospheric dust particles and water droplets settle and separate from the air, and thus effectively prevent the atmospheric dust particles and water droplets from entering the room.

[0060] In some other preferred embodiments, the first sand guard plate 14 includes an integrally formed first tooth plate 142, a first transverse plate 143 and a second tooth plate 144, and the first tooth plate 142 and the second tooth plate 144 are perpendicularly connected to both ends of the first transverse plate 143 in the width direction; the second sand guard plate 15 includes an integrally formed third tooth plate 152, a second transverse plate 153 and a fourth tooth plate 154, and the third tooth plate 152 and the fourth tooth plate 154 are perpendicularly connected to both ends of the second transverse plate 153 in the width direction; the orthographic projection of the first tooth plate 142 of the first sand guard plate 14 in the thickness direction overlaps with the second transverse plate 153 of an adjacent second sand guard plate 15; the orthographic projection of the second tooth plate 144 of the first sand guard plate 14 in the thickness direction overlaps with the second transverse plate 153 of another adjacent second sand guard plate 15.

[0061] It can be understood that in the thickness direction (air inlet direction), the orthographic projection of the first tooth plate 142 of the first sand guard plate 14 falls on the second transverse plate 153 between the third tooth plate 152 and the fourth tooth plate 154 of an adjacent second sand guard plate 15; the orthographic projection of the second tooth plate 144 of the first sand guard plate 14 falls on the second transverse plate 153 between the third tooth plate 152 and the fourth tooth plate 154 of another adjacent second sand guard plate 15. Thus, when the outdoor air enters the room, when passing through the louver structure 10, it has to make four turns before entering the room, effectively ensuring a reduction in the flow rate, so that the atmospheric dust particles and water droplets settle and separate from the air, and thus effectively prevent the atmospheric dust particles and water droplets from entering the room.

[0062] In some other preferred embodiments, L-shaped sand baffles 18 are further provided at both ends in the width direction of the first sand baffle mechanism 12 and the second sand baffle mechanism 13; it can be understood that when assembling the first sand baffle mechanism 12 and the second sand baffle mechanism 13, the width of the frame 11 may not necessarily be exactly such that an integer number of first sand baffles 14 and second sand baffles 15 can be assembled. By providing the L-shaped sand baffles 18 and arranging the L-shaped sand baffles 18 at both ends in the width direction, it is possible to avoid the two ends in the width direction of the louver structure 10, effectively reduce the flow rate of the intake air flow, and further cause atmospheric dust particles and water droplets to settle and separate from the air, thereby effectively preventing the atmospheric dust particles and water droplets from entering the room.

[0063] In some other preferred embodiments, the louver structure 10 is further provided with a wire mesh; the wire mesh is arranged between the second sand baffle mechanism 13 and the frame 11, or the wire mesh is arranged between the first sand baffle mechanism 12 and the frame 11. Preferably, in the present invention, the wire mesh is arranged between the second sand baffle mechanism 13 and the frame 11; that is to say, the wire mesh is installed between the air outlet end face 112 of the frame 11 and the second sand baffle mechanism 13 for preventing birds and insects from entering the room through the air inlet 16 and the air outlet 17; further, the wire mesh is made of 304 stainless steel wire mesh and can be set to 2 mesh, 5 mesh or 10 mesh.

[0064] In some other preferred embodiments, the frame 11 includes a first side frame 113, a second side frame 114, a top frame 115 and a bottom frame 116; the first side frame 113, the second side frame 114, the top frame 115 and the bottom frame 116 include an integrally formed sand baffle fixing part 117 and a window body fixing part 118; the sand baffle fixing part 117 is arranged in a U-shaped, and the window body fixing part 118 is arranged in an L-shaped. The fixing part is used to fix the first sand baffle mechanism 12 and the second sand baffle mechanism 13, and the window body fixing part 118 is used to connect to the wall.

[0065] It can be understood that by providing the window body fixing part 118, the louver structure 10 is installed in the wall; by providing the sand baffle fixing part 117, the first sand baffle mechanism 12 and the second sand baffle mechanism 13 are effectively fixed and installed, so as to effectively block the atmospheric dust particles and water droplets from entering the room.

[0066] In some other preferred embodiments, the louver structure 10 further includes a first connecting member 192 and a second connecting member 193. The first connecting member 192 is used to connect the top frame 115, the first side frame 113, the first dust baffle mechanism 12 and the second dust baffle mechanism 13; the second connecting member 193 is used to connect the top frame 115, the second side frame 114, the first dust baffle mechanism 12 and the second dust baffle mechanism 13. Further, the first connecting member 192 and the second connecting member 193 include a first connecting plate 194, a second connecting plate 195 and a third connecting plate 196, and the first connecting plate 194, the second connecting plate 195 and the third connecting plate 196 are integrally formed perpendicular to each other, thereby effectively improving the connection stability of the louver structure 10.

[0067] In some other preferred embodiments, through holes 119 are formed in the bottom frame 116, and the through holes 119 are used to discharge the atmospheric dust particles and water blocked by the first dust baffle mechanism 12 and the second dust baffle mechanism 13.

[0068] Further, the through holes 119 are formed between the first tooth plate 142 and the second tooth plate 144, and between the third tooth plate 152 and the fourth tooth plate 154; furthermore, 2 through holes 119 are formed between each group of the first tooth plate 142 and the second tooth plate 144, and 2 through holes 119 are formed between each group of the third tooth plate 152 and the fourth tooth plate 154; it can be understood that by forming the through holes 119, the dust particles and water can be quickly discharged, avoiding the accumulation of deposited dust particles and water in the louver structure 10, and ensuring the self-cleaning and maintenance-free of the louver structure 10.

[0069] It should be noted that the first dust baffle mechanism 12, the second dust baffle mechanism 13 and the frame 11 in the louver structure 10 provided in the present invention, as well as the wire mesh, are fixedly connected by riveting, or screwing, or by snap connection. As for the specific riveting structure, screwing structure and snap connection structure, they are prior arts and will not be described in detail in the present invention.

[0070] Please refer to Figures 10 to 14 , a louver system 1 is further provided in the second embodiment of the present invention, which includes the louver structure 10 as described in the above embodiment of the present invention. It can be understood that by adopting the louver structure 10 in the above embodiment in the louver system 1 provided in the present invention, when the louver system 1 supplements outdoor air into the room, it effectively avoids the collection of solid or non-aqueous particles such as dust, sand grains, and grit mixed in the outdoor air, as well as water droplets, etc. from entering the room and polluting the indoor environment; it also effectively avoids the accumulation of settled dust particles and water in the louver system 1, and ensures the self-cleaning of the louver system 1.

[0071] In some other preferred embodiments, the louver system 1 includes two or more louver structures 10 and a hourglass connector 20; the hourglass connector 20 is used to connect adjacent louver structures 10; at the same time, the hourglass connector 20 can also be used to guide the dust particles and water discharged from the through hole 119, which not only avoids the accumulation of dust particles and water in the louver structure 10, but also avoids the mutual contamination of the dust particles and water blocked between different louver structures 10. Further, adjacent louver structures 10 are connected in the height direction by the hourglass connector 20; it can be understood that by connecting multiple louver structures 10 through the hourglass connector 20, the louver system 1 can be adapted to the installation structure in walls of different sizes.

[0072] In some other preferred embodiments, the hourglass connector 20 includes a first connecting portion 21, a sand guiding plate 22 and a second connecting portion 23 which are integrally formed in a Z-shaped plate; the first connecting portion 21 is parallel to the outer surface of the relatively upper louver structure 10 and is adhesively connected to the outer surface of the louver structure 10, and cooperates with the sand guiding plate 22 and the second connecting portion 23 to carry the relatively upper louver structure 10; the sand guiding plate 22 is used to guide the dust particles and water flowing out of the relatively upper louver structure 10; the second connecting portion 23 is parallel to the outer surface of the relatively lower louver structure 10 and is adhesively connected to the inner surface of the louver structure 10, and cooperates with the sand guiding plate 22 and the first connecting portion 21 to carry the relatively upper louver structure 10. Specifically, the first connecting portion 21 of the hourglass connector 20 is connected to the sand baffle fixing portion 117 of the bottom frame 116 of the relatively upper end; the second connecting portion 23 of the hourglass connector 20 is connected to the sand baffle fixing portion 117 of the top frame 115 of the relatively lower end. Thereby effectively improving the stability of the hourglass connector 20 connecting the louver structure 10.

[0073] In summary, the present invention provides a louver structure and a louver system. The louver structure includes: a frame, the frame including an air inlet end face and an air outlet end face at both ends along the thickness direction; a first dust-proof plate mechanism disposed at the air inlet end face, including a plurality of first dust-proof plates arranged at equal intervals; a second dust-proof plate mechanism disposed at the air outlet end face, including a plurality of second dust-proof plates arranged at equal intervals; the first dust-proof plates and the second dust-proof plates are arranged in a staggered and alternating manner to block atmospheric dust particles and water droplets. It can be understood that the first dust-proof plate mechanism and the second dust-proof plate mechanism are installed on the inner circumferential surface of the frame. The first dust-proof plate mechanism is disposed at the air inlet end face, the second dust-proof plate mechanism is disposed at the air outlet end face, a plurality of first dust-proof plates are arranged at equal intervals in the first dust-proof plate mechanism, a plurality of second dust-proof plates are arranged at equal intervals in the second dust-proof plate mechanism, and at the same time, the first dust-proof plates and the second dust-proof plates are controlled to be arranged in a staggered and alternating manner; so that when the air enters the room through the louver structure, it first passes through between the second dust-proof plates, and then is blocked by the first dust-proof plates and passes through between the first dust-proof plates and the second dust-proof plates, and finally enters the room through the gap between two adjacent first dust-proof plates. During this process, the air flow velocity is blocked and reduced, so that the atmospheric dust particles and water droplets therein settle and separate from the air, thereby effectively preventing the atmospheric dust particles and water droplets from entering the room.

[0074] It should be understood that the application of the present invention is not limited to the above examples. For those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of the present invention.
