Abstract

A bladeless fan for producing air flows is characterized by comprising a base and a spray nozzle arranged on the base, wherein the spray nozzle comprises a first branch spray nozzle and a second branch spray nozzle and defines an opening, the first branch spray nozzle is connected with base, the second spray nozzle can rotate relative to the first branch spray nozzle from a non-inclined position to an inclined position, the first branch spray nozzle and the second branch spray nozzle are provided with internal cavities, the internal cavity of the first branch spray nozzle is communicated with the internal cavity of the second branch spray nozzle, and the length of the internal cavity of second branch spray nozzle is more than three times of the length of the internal cavity of the first branch spray nozzle. The invention further provides the spray nozzle for the bladeless fan.

Description

[0001] This application is a divisional application of a patent application with an application date of January 28, 2012, an application number of 201210019668.1, and an invention title of "Bladeless Fan and Nozzle for a Bladeless Fan". technical field [0002] The present invention relates to a bladeless fan for generating air flow and a nozzle for the bladeless fan. Background technique [0003] Bladeless fans are popular because they produce a smooth airflow without exposed rotating blades. The Chinese patent application (application number: 201010129999.1) published on September 8, 2010 with the announcement number CN101825104A discloses a bladeless fan for generating air flow. The fan includes: a base and a nozzle mounted on the base. The base A main body and a base are included, the main body is movable from an unreclined position to an inclined position relative to the base, each of the main body and the base having an outer surface, the joint portion of which is subs...
