▎ 摘　　要

NOVELTY - The mask has an inner cover (2) connected with a cover body (1). A glasses frame (3) is provided with a heating device i.e. graphite heating sheet, that is placed between the cover body and the inner cover. The graphite heating sheet is provided with a positive electrode, a negative electrode and a heating film. The heating film is divided into a set of filling cavities. Each filling cavity is filled with graphite alkene powder. A conductive wire is provided with multiple positive electrode branches. The negative electrode is provided with multiple conductive lines. USE - Graphene mask. ADVANTAGE - The mask is sanitary to use, and avoids need of directly contacting with a face of a user, and ensures uniform heating effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a graphene mask. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene mask.
