However, the building environment-friendly ventilation structure in reality will use bolts to fix and install filter screens inside the ventilation structure to improve air quality. When the accumulated dust is too much or the filter screen is saturated, the fresh air entering the indoor will be blocked, which not only causes the attenuation of fresh air volume, but also may bring some particulate matters into the indoor. At the same time, the existing ventilation structure is difficult to control the air volume and cannot be adjusted.
