Abstract

The invention discloses a bladeless fan, aiming at providing a bladeless fan with double air outlets. The bladeless fan is characterized by comprising a nozzle with an opening and an airflow device, wherein the airflow device is used for generating airflow passing through the nozzle; the nozzle comprises a first shell and a second shell; a first shell opening and a second shell opening are formed on the first shell and the second shell respectively, and are oppositely arranged; the end of the first shell opening at the opposite position is smaller than that of the second shell opening, and is positioned in the end of the second shell opening at the opposite position; the first shell opening and the second shell opening form overlapping parts at the opposite position; gaps are formed on the overlapping positions; and air outlets are formed on the gaps. Compared with the prior art, one more air outlet is formed on the bladeless fan, so that the wind blowing range is enlarged, and people feel cooler.

Description

technical field [0001] The present invention relates to a bladeless fan, more specifically, it relates to a bladeless fan with double outlets. Background technique [0002] At present, most of the fans on the market are still ordinary fans, that is, fans with blades, which are easy to carry dust and are not easy to disassemble and wash, and the setting of the blades also has certain dangers. In 2009, the UK launched the bladeless fan for the first time. Because this bladeless fan has no blades, it is more energy-saving, environmentally friendly and safer. Chinese patent application number 200910253241 discloses a bladeless fan, which includes a nozzle and means for forming an airflow through the nozzle, the nozzle includes an internal channel for receiving the airflow, a mouth and a spacer, wherein the airflow passes through a mouth defined by opposing surfaces of the nozzle, and spacer means for separating the opposing surfaces of the nozzle, the nozzle defining an opening...
