Description

Technical Field

[0001] The utility model relates to the technical field of graphene electric heating, in particular to a graphene electric heating device. Background Art

[0002] Graphene is one of the derivatives of graphite. The thickness of traditional graphite sheets is thicker than that of graphene. When the graphite sheets are peeled into single layers, this single layer with a thickness of only one carbon atom is graphene. Graphene is a single layer of graphite, and graphite can be regarded as a layer of multiple layers of graphene stacked up one by one. Graphite oxide is graphite oxidized by a strong oxidant to generate functional groups such as hydroxyl and carboxyl on the surface. After the graphite oxide is ultrasonically dispersed, due to the oscillation of ultrasound, the dispersion effect can easily disperse the graphite oxide into a lamellar structure, namely graphene oxide. Graphene oxide can be reduced by a reducing agent to obtain graphene.

[0003] Ordinary electric heating is the process of converting electrical energy into thermal energy by passing electricity through heating wires, resistance wires, etc. Graphene electric heating uses the conductivity of graphene materials for heating. The current is transmitted to the graphene, and the objects above it will be heated by thermal radiation. Since ordinary electric heating takes a certain amount of time to heat the heating wires, resistance wires and other heating bodies to a sufficient temperature, its heating speed is relatively slow, and there is a certain amount of energy waste. For some occasions that require rapid heating (such as floor heating systems, etc.), the traditional electric heating structure cannot meet people's needs for rapid heating. Therefore, a graphene electric heating device is urgently needed to solve the above problems. Utility Model Content

[0019] 3. In the utility model, by providing the groove, spring, first connecting block, second connecting block and anti-error block, when the staff needs to inspect and repair the electric heating device, they need to first remove the multiple sets of fixing bolts.
