Abstract (en)
[origin: WO2020034099A1] Provided is a spray head structure (1), comprising an airflow pipe (10), a rotary member (30), a load member (70), a fan component (100), a spoiler pipe (41) and a liquid flow pipe (50), wherein the rotary member (30) is rotatably sleeved on the airflow pipe (10), the load member (70) is mounted at the rotary member (30) to increase the load so as to improve the torsion of the rotary member, the fan component (100) is mounted at the rotary member (30), the spoiler pipe (41) is fixedly arranged on the rotary member (30) and is provided with a spoiler channel (41) in communication with the airflow pipe (10), and the spoiler channel (41) is provided with an outlet end (411), and an injection path forming an acute angle θ with the axis of the airflow pipe (10). Gas at a high flow rate enables the spoiler pipe to drive the rotary member to rotate relative to the airflow pipe, such that the fan component is driven to rotate to form an airflow, so that the air flow can flow from the fan component to the outlet end to improve the atomization effect thereof, or can flow from the outlet end to the fan component to perform the suction of impurities.
