[0002] Building ventilation refers to the circulation of air between the indoor and outdoor areas of a building. Through ventilation, indoor pollutants can be removed, the thermal comfort of indoor occupants can be ensured, and the need for fresh air can be met. It includes natural ventilation and mechanical ventilation. The ventilation method to be used is one of the important contents that need to be considered in the architectural design process. For example, windows are installed on the walls of a house, and natural ventilation can be achieved by opening the windows. Buildings such as factories and shopping malls are usually equipped with ventilation fans, ventilators or fresh air systems, etc., and mechanical ventilation methods with larger ventilation volume are used.

[0003] Drilling holes in the walls of buildings and installing suction fans is a common way of mechanical ventilation in buildings. Suction fans are usually fixed to the walls at the ventilation ducts with screws. After long-term use, a large amount of dust will adhere to the outer shell surface and the blade surface of the suction fan, which not only affects the heat dissipation of the outer shell of the suction fan, but also easily brings dust into the room during ventilation, affecting the cleanliness of the air.
