NOVELTY - The utility model claims a graphene heating device, comprising a shell, the middle part of the inner side of the shell is symmetrically equipped with two groups of graphene heating plate, two groups of opposite surfaces of the graphene heating plate are respectively extended with two groups of main guide sheet, two groups of the main guide sheet are staggered, the upper end face of the shell two groups of graphene heating plate is embedded with a shell, the inner side of the inner side of the shell of the shell is extended with multiple groups of dispersing plates outwards sequentially the lower end of the dispersing plate is extended with an extending piece, the upper end of the main guide sheet is embedded with multi-component clapboard, the separating plate is jointed between two groups of graphene heating plate, the extending piece is jointed with the separating plate. The utility model can improve the preheating quality, and can ensure the wind fully dispersed between two groups of graphene heating plate.
