The utility model provides a nozzle assembly, a spraying device and an unmanned aerial vehicle. The spray head assembly comprises a spray head, the main pipe, the at least two branch pipes and the atleast two nozzles are controlled to be opened and closed by impacting the pressure release valve through liquid pressure, different numbers of nozzles are opened, and the number of nozzles working atthe same time is changed, so that the spraying flow is changed, the nozzles are replaced without shutdown, the time for replacing the nozzles is saved, and the operation efficiency is improved. And onthe other hand, the user does not need to manually replace the nozzle to adjust the flow, so that the user is prevented from touching toxic liquid, and the user experience is improved. 本实用新型提供了一种喷头组件、喷洒装置与无人飞行器，其中喷头组件包括：主管、至少两个支管以及至少两个喷头，利用液体压力冲击泄压阀控制泄压阀的开启与闭合，实现开启不同数量的喷头，改变同时工作的喷头数量，从而实现改变喷洒流量，无需停机更换喷头，节省了更换喷头的时间，提高作业效率。另一方面，由于无需用户手动更换喷头以调节流量，避免用户触碰到有毒液体的情况发生，提高用户的使用体验。
