The invention discloses a spraying device assembly, a spraying system and unmanned equipment. The spraying device assembly comprises a spraying device, a flow guide pipe and an end opening pressure valve, wherein the spraying device is internally provided with a material cavity; the inlet end of the flow guide pipe is located outside the spraying device, and the outlet end of the flow guide pipe extends into the material cavity; and the end opening pressure valve is located in the material cavity and arranged at the outlet end of the flow guide pipe, the end opening pressure valve is configured to be opened when the material pressure in the flow guide pipe is larger than a preset value so that fluid in the flow guide pipe can flow into the material cavity, and the end opening pressure valve is closed when the material pressure in the flow guide pipe is smaller than the preset value, so that the fluid in the flow guide pipe is intercepted in the flow guide pipe. According to the spraying device assembly, the end opening pressure valve is arranged at the outlet end of the flow guide pipe, and accurate control over spraying is facilitated.
本发明公开了一种喷洒装置组件、喷洒系统及无人设备,所述喷洒装置组件包括:喷洒装置,所述喷洒装置内具有物料腔;导流管,所述导流管的入口端位于所述喷洒装置外,且所述导流管的出口端伸入所述物料腔内;端口压力阀,所述端口压力阀位于所述物料腔内,且安装至所述导流管的所述出口端,所述端口压力阀构造成在所述导流管内的物料压力大于预设值时打开,以使所述导流管内的流体流入所述物料腔,在所述导流管内的物料压力小于所述预设值时关闭,以将所述导流管内的流体截留在所述导流管内。根据本发明的喷洒装置组件,通过在导流管的出口端设置端口压力阀,有利于喷洒的精准控制。
