Abstract

The invention provides a bladeless fan used for generating air flow, and is characterized by comprising an airflow generation device, a nozzle, and an adjustment device arranged on the base and connected with the airflow generation device, wherein the adjustment device comprises a swing device connected with the base, a first component connected with the swing device, and a second component connected with the airflow generation device, the second component is rotatably connected with the first component, the nozzle comprises an inner channel and an exhaust port, at least one opening is limited, and air from exterior of the bladeless fan is entrained by airflow ejected from the exhaust port to pass through the opening. According to the device provided by the invention, a flow direction of the airflow can be adjusted in a large range according to requirements so as to meet different requirements of different users.

Description

technical field [0001] The invention relates to a bladeless fan for generating air flow. Background technique [0002] Bladeless fans are popular because they produce a smooth airflow without exposed rotating blades. The Chinese authorized patent (application number: 201020552115.9) with the authorized announcement number CN 201786779U on April 6, 2011 discloses a bladeless fan for generating air flow. The bladeless fan includes: an airflow generating device, a nozzle and a connection pipe, the nozzle includes an internal channel and an exhaust port and has a closed loop, the airflow generating device is used to generate high-pressure airflow and is at least partially located in the closed loop of the nozzle, the connecting pipe is connected to the Between the airflow generating device and the nozzle, a channel for the high-pressure airflow to flow from the airflow generating device to the nozzle is provided. [0003] This kind of bladeless fan is supported by a bracket, t...
