The invention relates to a fire extinguishing nozzle of an unmanned aerial vehicle. A rotating shaft is coaxially and rotatably connected to a cylinder seat; the nozzle is mounted at one end, far away from the barrel seat, of the rotating shaft, and a spray nozzle and a water spray nozzle are arranged in the nozzle; the plugs are connected with aqueducts; the first driving assembly is arranged on the barrel base and connected with the plug so as to drive the plug to move in the length direction of the rotating shaft, and connection and separation of the plug and the spray head are completed; the second driving assembly is arranged on the barrel base and connected with the rotating shaft, and the second driving assembly is used for rotating the spray head when the plug is separated from the spray head so as to switch the mist spray nozzle or the water spray nozzle. When the spray nozzle and the water spray nozzle need to be switched, the first driving assembly enables the plug to be separated from the spray head, then the second driving assembly rotates the spray head, after the second driving assembly rotates in place, the first driving assembly returns to the initial position, the plug is connected with the spray head again, different modes can be replaced, and the water spray requirement can be better met; and different fire conditions can be handled.

    本申请涉及一种无人机灭火喷头其包括:筒座上同轴转动连接有一转轴;喷头安装在所述转轴远离筒座的一端,并且其内设有喷雾喷嘴和喷水喷嘴;插头连接有导水管;第一驱动组件,其设置在所述筒座上,并与插头连接,以驱动插头沿转轴长度方向移动,完成与喷头的连接和分离;第二驱动组件设置在所述筒座上,并与所述转轴连接,第二驱动件用于在插头和喷头分离时,转动喷头,以进行切换喷雾喷嘴或喷水喷嘴。需要在喷雾喷嘴和喷水喷嘴之间进行切换时,第一驱动组件先使插头与喷头分离,然后第二驱动组件转动喷头,转动到位后,第一驱动组件回到初始位置,插头与喷头重新连接,可实现不同模式的更换,以更好的适应喷水需求,应对不同火灾情况。
