The performance of air vents, as one of the terminal devices of the ventilation system, directly affects the effect of the entire system. Currently, most air vent types are louver vents.

[0003] However, louvered air vents often lack dust prevention and automatic cleaning functions. Since the air vents are exposed to the external environment for a long time, dust is easily accumulated on the louvers regardless of whether they are in use or not. As a result, dust may be brought into the room when the louvered air vents are in use, affecting the air quality. When not in use, the accumulation of dust will affect the appearance of the air vents, and when they are activated again, the dust may be suddenly blown away, seriously affecting the air supply quality and the indoor environment, and may even cause health problems. Therefore, the air vents need to be cleaned. Currently, manual intervention is usually required when cleaning the air vents, which not only increases maintenance costs, but also reduces work efficiency.
