This creates a kind of unmanned flight's machine liquid spray structure improvement,Include: unmanned flight's machine and plural flusher,Unmanned flight's machine is equipped with a fuselage,The fuselage is equipped with a liquid storage tank and an at least power mechanism,The fuselage extends outward is equipped with plural cantilever,The plural number flusher averagely group sets the cantilevered distal end of what unmanned flight's machine two sides,Respectively the flusher separately included a bracket,Two spray lines,One conduit group and two sprinkler heads,The branch is provided with bifurcated bar,The two spray lines group is set on the what bifurcated bar,The conduit group to be connected to the liquid storage tank and two spray line,The two sprinkler heads group sets the what two spray lines lower end； Thereby,In order to reaching, spray area is big,It is small to spray spacing,Spraying efficiency is good.本創作一種無人飛行機液體噴灑結構改良，包含：一無人飛行機及複數噴灑裝置，該無人飛行機設有一機身，該機身上設有一液體儲存箱及至少一動力機構，該機身往外延伸設有複數懸臂，該複數噴灑裝置平均組設於該無人飛行機兩側之懸臂末端，各該噴灑裝置分別包含有一支架、二噴灑管、一導管組及二噴灑頭，該支架設有二分叉桿，該二噴灑管組設於該二分叉桿上，該導管組用以連通該液體儲存箱與該二噴灑管，該二噴灑頭組設於該二噴灑管下端；藉此，俾達噴灑面積大，噴灑間距小，噴灑效率佳。
