▎ 摘　　要

NOVELTY - The heating structure (10) has a successively stacked wooden protective layer, a graphene warm core layer, a plastic insulating layer and a bottom connection layer. The wooden protective layer is configured to cover one side of the graphene warm core layer, and the plastic insulating layer and the bottom connection layer are stacked and cover the other side of the graphene warm core layer. One end of the wooden protective layer is configured to protrude from one end of the plastic insulating layer to form a first step, and the other end of the plastic insulating layer protrude from the other end of the wooden protective layer to form a second step. The lateral length of the first step is the same as the lateral length of the second step. USE - Modular graphene floor heating structure of graphene floor heating system (claimed). ADVANTAGE - The modular graphene floor heating structure and floor heating system are provided with convenient installation and stable connection. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the modular graphene floor heating structure. Modular graphene floor heating structure (10)
