NOVELTY - The utility model claims a graphene powder spraying device, comprising a hollow shell, an electric telescopic rod, a piston and a controller; the top end of the shell is provided with a through hole; the telescopic rod of the outer diameter of the inner diameter of the through hole is slightly greater than the electric telescopic rod; the piston is set in the shell, the telescopic rod passes through said through hole and extends into the shell and is connected with the piston; one side of the shell is equipped with graphene powder supplying port is set on the bottom of the graphene powder spraying outlet; the electric telescopic rod is electrically connected with the controller; the controller is electrically connected with a control button. The utility model creates a high-pressure jet is alkene powder by adopting the piston pressurized condition, and the electric telescopic rod controlled by the controller for driving the piston operation can improve the automatic performance and the controllability of the graphene powder injection, and finally improve the precision of the graphene powder injection.
