Abstract (en)
[origin: EP3726066A1] A fan head assembly for a bladeless air-blowing apparatus, a bladeless air-blowing apparatus, a head (100) for a bladeless fan (1000), and a bladeless fan (1000). The fan head assembly comprises an air outlet portion (10). The air outlet portion (10) comprises an air inlet (13), a nozzle (12), and an air duct (11). Both the air inlet (13) and the nozzle (12) communicate with the air duct (11). The air duct (11) has a variable cross-section part. An airflow passage area of the variable cross-section part continuously switches from bottom to top, and the airflow passage area at the lower end of the variable cross-section part is larger than the airflow passage area at the upper end. The configuration allows a flow rate of an inlet airflow to increase when the inlet airflow passes through the variable cross-section part, such that the flow rate of the airflow output from an upward nozzle and a downward nozzle at the variable cross-section part is uniform, thereby improving the user experience.
