Abstract

The invention provides an air duct structure of a bladeless fan and the bladeless fan. The air duct structure comprises an air outlet part and an air inlet part, an air outlet duct is formed in the air outlet part, a plurality of air outlets are formed in the side, in the length direction, of the air duct wall of the air outlet duct, an air guide structure is formed on the other side, deviating from the air outlets, of the air duct wall of the air outlet duct, the air guide structure comprises a first air guide section and a second air guide section which are arranged in the airflow direction, the first air guide section is located on the upstream of the second air guide section, the air outlet end of the second air guide section extends to the top of the air outlet duct, the first air guide section forms a cambered surface which is gradually shrunk towards the central axis of the air outlet duct, the second air guide section forms a cambered surface which is gradually expanded towards the central axis of the air outlet duct, an air inlet is formed in the air inlet part and communicates with the air outlet duct, and the air inlet end of the first air guide section extends to be connected to the air inlet part. According to the air duct structure, the aerodynamic noise of the bladeless fan can be effectively reduced, and the air outlet volume can be increased.

Description

technical field [0001] The invention belongs to the field of bladeless fans, and in particular relates to an air passage structure of a bladeless fan and the bladeless fan. Background technique [0002] Compared with the traditional axial fan, the bladeless fan on the market today has a more stable airflow without the impact of the airflow and wave-shaped stimulation, and the energy consumption of the bladeless fan is lower. Through the unique The air duct is designed to increase the speed of the outlet airflow, and under the action of the gas viscous force, the outlet airflow drives the airflow in the annular ring to realize the multiplication of the airflow. [0003] In terms of appearance, since the blades of the bladeless fan are hidden in the fan base, users cannot directly touch the blades, which is safer than traditional fans, and has a unique appearance, which is more technologically aesthetic and innovative. [0004] However, bladeless fans are noisier than traditi...
