[0002] Green buildings generally refer to high-quality buildings that save resources, protect the environment, reduce pollution, provide people with healthy, applicable and efficient use space, and maximize the harmonious coexistence of man and nature throughout their entire life cycle. The ventilation structure is the most important component of a green building.

[0003] Currently available ventilation structures generally only have ventilation effects, and do not consider sealing the ventilation structures when ventilation is not needed. Especially in winter, cold air will enter the room through the ventilation structures, causing the indoor temperature to be too low, thus affecting daily living. Utility Model Content

[0024] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0025] See also Figure 1-6 A green building energy-saving ventilation structure includes a ventilation box, wherein one end of the ventilation box 1 is open, and the open setting facilitates air circulation. A first filter plate 2 is detachably provided at the open end of the ventilation box 1. The first filter plate 2 can reduce dust in the air and debris outside from entering the ventilation box 1, thereby avoiding blockage inside the ventilation structure and affecting the ventilation of the device. A fan 3 is provided inside the ventilation box 1, and the fan 3 is a necessary mechanism for achieving ventilation; a fixed ring 4 is fixedly connected to the other end of the ventilation box 1, and a rotating ring 5 is rotatably connected to the ventilation box 1 inside the fixed ring 4. Three fan-shaped closed leaves 6 are fixedly connected to the outer ring of the rotating ring 5 in a circular array, and fan-shaped vents 7 corresponding to each fan-shaped closed leaf 6 are provided on the ventilation box 1. The fan-shaped vents 7 cooperate with the fan-shaped closed leaves 6 to control the circulation of air.

[0026] Furthermore, the open end of the ventilation box 1 is fixedly connected to a first square fixing ring 8, and a number of matching bolt holes 9 are provided on the first square fixing ring 8 and the first filter plate 2, and a fixing bolt 10 is passed through each bolt hole 9. The first filter plate 2 is detachably connected to the ventilation box 1 through the cooperation among the fixing bolts 10, the bolt holes 9 and the first square fixing ring 8. The first filter plate 2 is detachably connected to the ventilation box 1, which makes it convenient to disassemble the first filter plate 2 for cleaning, and ensures that the filter holes on the first filter plate 2 will not be blocked, thereby affecting the air circulation.

[0027] Furthermore, the middle outer ring of the ventilation box 1 is fixedly connected to a second square fixing ring 11, and a plurality of fixing holes 12 are passed through the second square fixing ring 11. The fixing holes 12 can be opened to install the ventilation box 1 on the wall using screws.

[0028] Furthermore, a slot 13 is provided on the top of the ventilation box 1, and a second filter plate 14 is inserted in the slot 13. The second filter plate 14 can move in the slot 13. The second filter plate 14 can prevent indoor insects and other organisms from entering the ventilation box 1, and can further prevent dust in the outdoor air from entering the room. The second filter plate 14 fits with the fan-shaped vent 7. The provision of the slot 13 can facilitate the disassembly and assembly of the second filter plate 14, and facilitate the cleaning of the second filter plate 14.

[0029] Furthermore, a first limiting hole 15 and a second limiting hole 16 are provided on the fixing ring 4, and a limiting column 17 is fixedly connected to one of the fan-shaped closing leaves 6, and a limiting bolt 18 is passed through the limiting column 17; the limiting bolt 18 is movable relative to the limiting column 17, and when the limiting bolt 18 passes through the limiting column 17 and the first limiting hole 15, the fan-shaped closing leaf 6 is aligned with the fan-shaped vent 7; when the limiting bolt 18 passes through the limiting column 17 and the second limiting hole 16, the fan-shaped closing leaf 6 is staggered with the fan-shaped vent 7. The arrangement of the first limiting hole 15, the second limiting hole 16, the limiting column 17 and the limiting bolt 18 can limit the fan-shaped closing leaf 6 when it rotates, so that the fan-shaped closing leaf 6 and the fan-shaped vent 7 can be precisely staggered to achieve ventilation; or precisely aligned to achieve closure and block air circulation; the position of the fan-shaped closing leaf 6 can also be fixed so that it will not be affected by the wind in the air and will not be offset.

[0030] Furthermore, the ventilation box 1 is fixedly connected to a positioning column 19 that passes through the rotating ring 5, and a nut 20 is threadedly connected to the outer end of the positioning column 19. The setting of the nut 20 can disassemble and assemble the rotating ring 5 mounted on the positioning column 19 and the fan-shaped closing leaf 6 fixedly connected to the rotating ring 5; the rotating ring 5 is rotatably connected to the ventilation box 1 through the cooperation of the positioning column 19 and the nut 20.

[0031] When in use, first start the fan 3, then rotate the fan-shaped closing leaf 6 to align the limit column 17 with the second limit hole 16. At this time, the fan-shaped closing leaf 6 will be staggered with the fan-shaped vent 7, and then the limit bolt 18 is inserted into the limit column 17 and the second limit hole 16 to fix it. The air circulates through the first filter plate 2, the ventilation box 1, the second filter plate 14 and the fan-shaped vent 7, thereby achieving ventilation; when ventilation is not required, rotate the fan-shaped closing leaf 6 to align the limit column 17 with the first limit hole 15, and then insert the limit bolt 18 into the limit column 17 and the first limit hole 15 to fix it, achieving sealing, thereby blocking the air circulation.
