Xiaomi has launched a new product under the Youpin platform. The product is the Daewoo F9 Bladeless fan. A bladeless fan is also called an air multiplier and is a fan which blows air from a ring with no external blades. Its vanes are hidden in its base and direct the collected airflow through a hollow tube or toroid, blowing a thin high-velocity smooth airflow from holes or a continuous slot across the surface of the tube or toroid. 
Due to the absence of physical blades, the fan will not generate dust or hurt children’s fingers. What is even more amazing is that it has a strange shape and a streamlined appearance. Daewoo’s F9 Bladeless Fan adopts a working mechanism similar to other known brands like Dyson. The air is drawn in by a compressor in the base and then directed up into a ring. It comes out of a slit around the ring and passes over a shape like that of an aircraft wing (Coanda effect).
