[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0004] However, existing patents have the following drawbacks:

[0005] (1) When the ventilation structure is not working, dust or even small animals may enter the room through the air duct, polluting the indoor environment.

[0006] (2) The filter screen and fan blades are not easy to clean. After a long period of use, a lot of dust will be attached to the filter screen and fan blades, which will affect ventilation. Utility Model Content

[0007] The purpose of this utility model is to provide a ventilation structure for green buildings, which solves the problems of existing technology being unable to seal the air duct and being inconvenient to clean by setting a closable baffle and a detachable filter frame.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A ventilation structure for a green building includes:

[0010] The air duct has a protective box fixedly connected to the inner wall of the front part, and an insertion hole is opened on the rear side surface of the upper end of the air duct.

[0011] The first motor is located inside the air duct. Several fan blades are fixedly connected to the front end of the first motor. A fixed frame is fixedly connected to the surface of the first motor. The air duct is fixedly connected to both the left and right ends of the fixed frame.

[0012] A rotating shaft, several of which are equally spaced inside the front end of the air duct, the left and right ends of the rotating shaft are rotatably connected to the protective box and the air duct respectively, a baffle is fixedly connected to the surface of the rotating shaft, and a first bevel gear is fixedly connected to the left end of the rotating shaft, the first bevel gear being located inside the protective box;

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-7 A ventilation structure for a green building includes a duct 1. A protective box 101 is fixedly connected to the inner wall of the front part of the duct 1. An insertion hole 102 is opened on the rear surface of the upper end of the duct 1. A first motor 2 is located inside the duct 1. Several fan blades 201 are fixedly connected to the front end of the first motor 2. A fixing frame 202 is fixedly connected to the surface of the first motor 2. The duct 1 is fixedly connected to both ends of the fixing frame 202, which can fix the first motor 2. The first motor 2 can drive the fan blades 201 to rotate, thereby ventilating. Several equally spaced rotating shafts 3 are located inside the front end of the duct 1. The left and right ends of the rotating shafts 3 are rotatably connected to the protective box 101 and the protective box 101 respectively. A baffle 301 is fixedly connected to the surface of the duct 1 and the rotating shaft 3. The baffle 301 can rotate with the rotating shaft 3, thereby changing the closed state. A first bevel gear 302 is fixedly connected to the left end of the rotating shaft 3. The first bevel gear 302 is located inside the protective box 101. A filter frame 4 is movably connected inside the duct 1. A filter screen 402 is fixedly connected inside the filter frame 4 to filter dust in the air. A protruding plate 401 is fixedly connected to the upper part of the filter frame 4. A locking component 5 is inside the protruding plate 401 to fix the filter frame 4 inside the duct 1. An adjustment component 6 is inside the protective box 101 to adjust the angle of the baffle 301.

[0035] Specifically, the locking component 5 includes a fixing cylinder 501, which is fixedly connected to a protruding plate 401. A pin 502 is slidably connected inside the fixing cylinder 501. The pin 502 is slidably connected to the protruding plate 401. A pull ring 503 is fixedly connected to the lower end of the pin 502 for easy pulling. A limit ring 504 is fixedly connected to the surface of the pin 502. A spring 505 is located at the bottom of the limit ring 504. The spring 505 is sleeved on the pin 502. The spring 505 will use its elasticity to push the pin 502 into the insertion hole 102, thereby fixing the filter frame 4.

[0036] Using the above technical solution, by pulling the pull ring 503 to disengage the pin 502 from the insertion hole 102, the filter frame 4 can be removed.

[0037] Specifically, the adjustment component 6 includes a micro motor 601, which is fixedly connected to the upper part of the protective box 101. A drive shaft 602 is fixedly connected to the bottom of the micro motor 601. The micro motor 601 can control the rotation of the drive shaft 602. The bottom of the drive shaft 602 is rotatably connected to the protective box 101. Several equally spaced second bevel gears 603 are fixedly connected to the surface of the drive shaft 602. The second bevel gears 603 correspond one-to-one with the first bevel gears 302. The second bevel gears 603 mesh with the first bevel gears 302. The second bevel gears 603 can drive multiple rotating shafts 3 to rotate simultaneously through the first bevel gears 302.

[0038] Through the above technical solution, the micro motor 601 can drive the transmission shaft 602 to rotate. The transmission shaft 602 drives the rotating shaft 3 to rotate through the first bevel gear 302 and the second bevel gear 603. When the baffle 301 is erected, it can seal the air duct 1 to prevent debris from entering.

[0039] When in use, install the duct 1 inside the wall, start the first motor 2 to rotate the fan blade 201 for ventilation. When ventilation is not needed, turn off the first motor 2 and start the micro motor 601. The micro motor 601 drives the transmission shaft 602 to rotate. The transmission shaft 602 drives the rotating shaft 3 to rotate through the first bevel gear 302 and the second bevel gear 603. The baffle 301 is raised to seal the duct 1 and prevent debris from entering. When dust needs to be cleaned, pull the pull ring 503 to disengage the pin 502 from the socket 102, and the filter frame 4 can be removed for cleaning of the filter 402 and the fan blade 201.
