Abstract

The present invention relates to a fan device, in particular to a bladeless fan assembly. The fan assembly includes a nozzle mounted on a base, the base further includes a base and a column, and a swing mechanism is arranged between the base and the column. The present invention provides a bladeless fan assembly whose air flow area can be automatically adjusted, and is more comfortable to use.

Description

technical field [0001] The invention relates to a fan device, in particular to a bladeless fan assembly. Background technique [0002] The usual fan is blade-type, and the blades rely on their lift angles during the rotation process to form forward wind force. The wind of this traditional fan is intermittent, and the impact of the wind pulsatingly on the human body will cause discomfort. [0003] Later, people used the principle of continuous wind and the amplification effect of the Coanda surface to produce a bladeless fan, which solved the above problems. For example, the "Fan" disclosed in the Chinese patent document CN101424279A on May 6, 2009 belongs to the bladeless fan, and the invention discloses a fan device for generating air flow. A bladeless fan assembly is provided that includes a nozzle and means for generating air flow through the nozzle. The nozzle includes an internal passage, an exhaust port for receiving airflow from the internal passage, and a Coanda s...
