Graphene heating floor with good heat retaining property

The graphene heating floor with the good heat preservation performance comprises a floor body, a fixing shell is fixedly connected to the bottom of the floor body and used for installing and fixing graphene strips in the floor body, and a plurality of graphene strips are evenly and fixedly connected to the inner bottom of the fixing shell and used for installing and fixing the graphene strips in the fixing shell. A first connecting block is fixedly connected to the middle of the side wall of the fixing shell, a connecting inserting rod is fixedly connected to the end face of the first connecting block, and a second connecting block is fixedly connected to the middle of the side wall, away from the first connecting block, of the fixing shell. And a connecting socket is formed in the end surface of the second connecting block. The graphene heating assembly is arranged at the bottom of the floor, so that the used floor can be heated, meanwhile, the clamping assembly is arranged at the joint of the floor, the flo
