Abstract: A bladeless air fan includes a host and an airflow guiding frame. The host divides into a housing section to hold an airflow generator and a pivoting section to include two first pivoting portions. The airflow generator is connected to an airflow guiding manifold extended from the housing section to the pivoting section. The airflow guiding frame includes an air discharging portion and an airflow guiding passage and two second pivoting portions being annular to form two air intake ports communicating with the airflow guiding passage. The second pivoting portions are rotatably coupled with the first pivoting portions such that the airflow guiding passage communicates with the airflow guiding manifold. The air discharging portion encircles an airflow passage being formed at an inner diameter allowing the housing section to pass through to enlarge the range of the second pivoting portions rotating against the first pivoting portions.
