The invention provides an unmanned aerial vehicle for water paint spraying, and belongs to the technical field of unmanned aerial vehicle spraying construction. Comprising an unmanned aerial vehicle body, two extension pipes, a storage barrel fixed below the unmanned aerial vehicle body and an air pump, the two air pipes are coaxial, the unmanned aerial vehicle body is located between the two extension pipes, the inner ends of the extension pipes are fixedly connected with the unmanned aerial vehicle body, and the air outlet end of the air pump is connected with a first air outlet pipe and a second air outlet pipe in parallel; the outer ends of the first air outlet pipe and the second air outlet pipe are each connected with a nozzle. A piston longitudinally slides in the material storage barrel, the piston divides the material storage barrel into an upper cavity and a lower cavity, water paint is stored in the lower cavity, the first air outlet pipe is connected with the air receiving end of a spray nozzle for spraying, the bottom of the lower cavity is connected with the material receiving end of the spray nozzle for spraying, and the second air outlet pipe is connected with the upper cavity. The upper cavity is connected with the gas receiving end of a nozzle used for spraying gas reversely, and a pressure limiting valve is arranged in the exhaust pipe. The device has the advantages that the spraying quality can be improved, and the like.
