[0001] This utility model relates to the field of building ventilation technology, and in particular to a green building ventilation structure. Background Technology
[0002] Green building refers to high-quality buildings that maximize resource conservation, environmental protection, and pollution reduction throughout the entire life cycle of a building, providing people with healthy, suitable, and efficient living spaces, and coexisting harmoniously with nature. In order to save resources, protect the environment, improve indoor air quality, promote human health and comfort, and drive the development of green buildings, a green building ventilation structure is needed.
[0003] A green building ventilation structure is a building structure component used in green buildings to achieve indoor and outdoor air exchange while taking into account multiple functions such as environmental protection, energy saving, and comfort. In the past, in green building ventilation structures, the filter screen was usually placed inside the ventilation structure shell. Such a design may cause the filter screen to be installed in a hard-to-reach location, or the replacement process may require the disassembly of a large number of parts, making filter screen replacement time-consuming and laborious, thus leading to increased maintenance costs. Therefore, the previous green building ventilation structures could not achieve the effect of quick filter screen replacement. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a green building ventilation structure, which aims to improve the problem that previous green building ventilation structures could not achieve rapid filter replacement.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A green building ventilation structure includes a first ventilation duct. A support plate is fixedly connected to the outer wall of the first ventilation duct. A handle is rotatably connected to the inside of the support plate. A first gear is fixedly connected to the outer wall of the handle. The outer wall of the first gear is rotatably connected to the inside of the support plate. A rack is meshed with the tooth end of the first gear. A spring is fixedly connected to the outer wall of the rack. The outer walls of the rack and the spring are slidably connected to the inside of the support plate. A locking rod is fixedly connected to the outer wall of the rack. A connecting block is slidably connected to the outer wall of the locking rod. A locking groove is formed inside the connecting block. The outer wall of the locking rod is slidably connected to the inner wall of the locking groove. A filter screen is fixedly connected to the outer wall of the connecting block. A connecting frame is fixedly connected to the outer wall of the first ventilation duct. The outer wall of the filter screen is slidably connected to the inside of the connecting frame. A ventilation component is provided on the outer wall of the first ventilation duct for auxiliary ventilation.
[0007] Preferably, the ventilation assembly includes a support frame, the interior of which is fixedly connected to the outer wall of the first ventilation duct, and the outer wall of the support frame is fixedly connected to the second ventilation duct.
[0008] Preferably, a motor is fixedly connected to the outer wall of the support frame, and a second gear is fixedly provided at the output end of the motor.
[0009] Preferably, the tooth end of the second gear is meshed with a toothed ring, and a locking block is fixedly connected to the outer wall of the toothed ring.
[0010] Preferably, a limiting groove is provided inside the support frame, and the outer wall of the card block is rotatably connected to the inner wall of the limiting groove.
[0011] Preferably, the tooth ends of the toothed ring are engaged with sector gears.
[0012] Preferably, the sector gear is internally fixedly connected to a fixed shaft, and the outer wall of the fixed shaft is rotatably connected to the inside of the support frame.
[0013] Preferably, a connecting plate is fixedly connected to the outer wall of the sector gear, and the outer wall of the connecting plate is slidably connected to the inside of the support frame.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, turning the handle drives the first gear to rotate, which in turn drives the rack to slide in the support plate.

[0016] 2. In this utility model, the motor drives the second gear to rotate, which in turn drives the gear ring to rotate. Then, the gear ring drives the locking block to slide in the limiting groove. In addition, the gear ring drives the sector gear to rotate while controlling the closing of the connecting plate, thus achieving the effect of adjusting the ventilation size as needed. This allows the ventilation system to flexibly control the ventilation volume according to the actual indoor and outdoor conditions. Attached Figure Description

Detailed Implementation
[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a green building ventilation structure, including a first ventilation pipe 1. A support plate 2 is fixedly connected to the outer wall of the first ventilation pipe 1. A handle 3 is rotatably connected to the inside of the support plate 2. A first gear 4 is fixedly connected to the outer wall of the handle 3. The outer wall of the first gear 4 is rotatably connected to the inside of the support plate 2. A rack 5 is meshed with the tooth end of the first gear 4. A spring 6 is fixedly connected to the outer wall of the rack 5. The outer walls of the rack 5 and the spring 6 are slidably connected to the inside of the support plate 2. A locking rod 7 is fixedly connected to the outer wall of the rack 5. A connecting block 8 is slidably connected to the outer wall of the locking rod 7. A slot 9 is opened inside the connecting block 8. The outer wall of the locking rod 7 is slidably connected to the inner wall of the slot 9. A filter screen 10 is fixedly connected to the outer wall of the connecting block 8. A connecting frame 11 is fixedly connected to the outer wall of the first ventilation pipe 1. The outer wall of the filter screen 10 is slidably connected to the inside of the connecting frame 11. A ventilation component is provided on the outer wall of the first ventilation pipe 1 for auxiliary ventilation.
[0026] Specifically, turning the handle 3 drives the first gear 4 to rotate, which in turn drives the rack 5 to slide in the support plate 2. At the same time, it compresses the spring 6, which in turn drives the locking rod 7 to slide in the slot 9 on the connecting block 8. When the locking rod 7 slides out, it loses its engagement with the connecting block 8. By pulling the connecting block 8, the connecting frame 11 in the filter screen 10 can be removed. When the filter screen 10 is installed, the spring 6 keeps the locking rod 7 firmly locked in the connecting block 8.
[0027] Reference Figure 1 The ventilation assembly includes a support frame 12, the inside of which is fixedly connected to the outer wall of the first ventilation duct 1, and the outer wall of the support frame 12 is fixedly connected to a second ventilation duct 13.
[0028] Specifically, the support frame 12 serves to support and fix the first ventilation pipe 1 and the second ventilation pipe 13, both of which serve the function of ventilation.
[0029] Reference Figure 1 , Figure 4 and Figure 5 A motor 14 is fixedly connected to the outer wall of the support frame 12, and a second gear 15 is fixedly installed at the output end of the motor 14; a gear ring 16 is meshed with the tooth end of the second gear 15, and a locking block 20 is fixedly connected to the outer wall of the gear ring 16; a limiting groove 21 is opened inside the support frame 12, and the outer wall of the locking block 20 is rotatably connected to the inner wall of the limiting groove 21; a sector gear 17 is meshed with the tooth end of the gear ring 16; a fixed shaft 18 is fixedly connected inside the sector gear 17, and the outer wall of the fixed shaft 18 is rotatably connected to the inside of the support frame 12; a connecting plate 19 is fixedly connected to the outer wall of the sector gear 17, and the outer wall of the connecting plate 19 is slidably connected to the inside of the support frame 12.
[0030] Specifically, the motor 14 first drives the second gear 15 to rotate, the support frame 12 limits the second gear 15, the second gear 15 drives the gear ring 16 to rotate, the gear ring 16 drives the locking block 20 to slide in the limiting groove 21, and then the gear ring 16 drives the sector gear 17 to rotate on the fixed shaft 18, thereby controlling the closing of the connecting plate 19, thus achieving the effect of adjusting the ventilation size as needed, and enabling the ventilation system to flexibly control the ventilation volume according to the actual indoor and outdoor conditions.
[0031] Working principle: When this structure is needed, the motor 14 first drives the second gear 15 to rotate inside the support frame 12. The second gear 15 drives the gear ring 16 to rotate, which in turn drives the locking block 20 to slide in the limiting groove 21. The gear ring 16 then drives the sector gear 17 to rotate on the fixed shaft 18, simultaneously controlling the closing of the connecting plate 19. When the filter screen 10 needs to be replaced, turning the handle 3 drives the first gear 4 to rotate. The first gear 4 drives the rack 5 to slide in the support plate 2, simultaneously compressing the spring 6. The rack 5 then drives the locking rod 7 to slide in the slot 9 on the connecting block 8, thus allowing the locking rod 7 to... With the connecting block 8 released from its engagement, the filter 10 can be removed from the connecting frame 11 by pulling the connecting block 8. This structure not only achieves the effect of quick and on-demand replacement of the filter 10, but also ensures that the filtration effect of the ventilation system remains at a high level. During use, the filter 10 will gradually accumulate pollutants such as dust, pollen, and particulate matter. As the amount of pollutants increases, the filtration efficiency of the filter 10 will decrease. Timely replacement of the filter 10 can effectively prevent these pollutants from entering the room, thus providing cleaner indoor air. It also achieves the effect of adjusting the ventilation volume as needed, allowing the ventilation system to flexibly control the ventilation volume according to the actual indoor and outdoor conditions. When the indoor air quality is good, or the outdoor air quality is poor, the ventilation volume can be appropriately reduced to avoid unnecessary energy loss.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
