Patent ID: 8529226

Claim:
A bladeless air fan, comprising: a host divided into a housing section and a pivoting section extending from the housing section to hold an airflow guiding manifold, the housing section holding an airflow generator, the pivoting section including two first pivoting portions, the airflow generator being connected to the airflow guiding manifold, the airflow guiding manifold being extended from the housing section to the pivoting section and communicating with the first pivoting portions; and an airflow guiding frame which includes an air discharging portion, two second pivoting portions, and an airflow guiding passage formed in the air discharging portion, the second pivoting portions being annular to form two air intake ports communicating with the airflow guiding passage, the air discharging portion encircling an airflow passage to allow air to pass through axially, the second pivoting portions being rotatably coupled to the first pivoting portions such that the airflow guiding passage communicates with the airflow guiding manifold, the air flow passage being formed at an inner diameter of the airflow guiding frame such that the housing section is allowed to pass through the air flow passage in order to increase the pivotable range of the first pivoting portions with respect to the second pivoting portions.
