▎ 摘　　要

NOVELTY - The floor heating device has a heating cable (2) that is laid on the upper surface of an aluminum film (1). A sliding sleeve is clamped on the upper surface of a support plate. The support plate is fixedly connected to the bottom of a floor (7). The surface of a sliding rod is sleeved with a first spring. The top and bottom ends of the first spring are fixedly connected to the lower surface of the support plate and the lower surface of the inner wall of the groove. The left and right sides of the lower surface of the support plate are fixedly connected to the upper surface of a reinforcing plate (4) through a second spring. The heating cable includes a wire sleeve (201) that is made of silicone rubber. The wire sleeve is provided with two electrodes (202). The outer surfaces of the electrodes are provided with a graphene and polyethylene mixed filling layer (203). The graphene and polyethylene mixed filling layer are located in a wire sleeve. USE - Floor heating device with built-in heating cable protection function. ADVANTAGE - The effect of the aluminum film prevents the heat transferred by the graphene and polyethylene mixed filling layer from being transmitted below the aluminum film, and improves the heat transfer. The heat conduction effect is achieved. The heat conduction effect effectively plays a role of high efficiency and energy saving when the heating temperature of the device is higher, and the energy consumption is lower. The impact force of the electrode is reduced. The floor heating with built-in heating cable protection function increases the strength of the expanded polyethylene foam (EPE) floor heating reflective film by providing a reinforcing plate, and avoids the EPE floor heating reflective film from easily deforming, thus, protects the floor heating and provides a stable support for the floor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural view of floor heating device.
