Patent abstract
A bladeless fan includes a wind supply device and a first wind guide device disposed on the wind supply device and having a loop-shaped space. Airflow is created by the wind supply device, and enters the loop-shaped space. When the airflow exits the loop-shaped space through an air outlet, surrounding air is forced to flow through a flow guide channel in the first wind guide device to combine with the air flowing from the air outlet, so as to increase the amount and speed of the airflow.
