摘要： An axial flow fan blade, a blade assembly for axial flow fan, and an air duct assembly for axial flow fan. Wherein, an air guide section is formed on an end of an windward edge of the axial flow fan blade (1) proximal to a blade tip, a plurality of air guide grooves (2) are disposed on the air guide section; the air guide section satisfies that the condition of (r 2 -r 1 ):r =1/3-1/2, and a depth of the air guide grooves (2) is gradually reduced along a direction running toward the rotation center. The air guide section of the axial flow fan blade can divide an airflow into small airflows so as to achieve the noise reduction effect. Moreover, the air guide groove has gradually reduced depth, thereby ensuring uniform air speed.

摘要： 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.
