Description

Technical Field

[0001] The utility model relates to the technical field of bladeless fans, in particular to a bladeless fan with spray humidification and heating functions. Background Art

[0002] Unlike traditional fans, bladeless fans do not have obvious blades. The working principle is that air is sucked in through a small motor and blade device in the base or body, and then the air is accelerated through the channel inside the fan and ejected through a narrow annular opening. The ejected high-speed air uses the induced effect to drive the surrounding still air together, forming a strong and stable airflow.
