The invention provides a pressure spray head and a plant protection unmanned aerial vehicle, and relates to the technical field of plant protection unmanned aerial vehicles, the pressure spray head comprises a spray head body, a reversing valve element and a motor rotor, the spray head body comprises a flow dividing cavity, a reversing valve shell and a nozzle, and the reversing valve shell is a cylindrical shell; the reversing valve shell comprises a first inlet, a second inlet, a first outlet, a second outlet, a third outlet and a fourth outlet, the first inlet and the second inlet are communicated with the flow dividing cavity, and the first outlet, the second outlet, the third outlet and the fourth outlet are communicated with the nozzle. Wherein one channel opening is communicated with one inlet, and the other channel opening communicated with the channel opening is communicated with one outlet, so that liquid medicine can be sprayed through different outlets by driving the reversing valve element to rotate, and the spraying efficiency can be improved while the situation that spraying work is stopped due to the fact that a spray head is damaged can be avoided.

    本申请提供了一种压力喷头及植保无人机,涉及植保无人机技术领域,该压力喷头包括喷头主体、换向阀芯和电机转子,喷头主体包括分流腔体、换向阀壳体和喷嘴,换向阀壳体为圆柱壳体,换向阀壳体包括第一入口、第二入口、第一出口、第二出口、第三出口以及第四出口,第一入口和第二入口分别与分流腔体连通,第一出口、第二出口、第三出口以及第四出口分别与喷嘴连通,当电机转子驱动换向阀芯旋转至第一状态或第二状态,其中一个通道口与其中一个入口连通,与其连通的另一通道口与其中一个出口连通,旨在通过驱动换向阀芯的转动,使得药液可以通过不同出口进行喷洒,可以避免喷头损坏导致喷洒工作停止的同时提高喷洒效率。
