At present, in the market, the heating elements in water are made of stainless steel materials, the phenomena of scaling on the surface of the heating pipe, corrosion and the like are easy to occur, particularly, in some areas, the water quality is poor and contains a large amount of salts such as calcium, magnesium and the like, the physical and chemical reactions are generated in the heating process to form scale, and the scale is attached to the surface of the heating pipe, so that the heat generated inside cannot be rapidly dissipated. The phenomenon of electric leakage after the pipe is directly corroded and perforated due to poor water quality is easy to occur, the service life of a heating element is greatly shortened, most of common anti-corrosion and scale coatings in the market are subjected to enamel treatment or Teflon treatment on the surface of the heating pipe, due to the characteristics of enamel materials, the coatings are easy to spray unevenly, the surface coatings of the enamel heating pipes in the production and transportation processes are easy to damage, the heat dissipation of the pipe surface is uneven, the attractiveness is affected, and the product service life cost is higher. The teflon-coated heating tube has excellent aging resistance, but its maximum temperature resistance does not exceed 300 ℃. Although the traditional coating has a certain function of corrosion resistance, the effect is not ideal enough, and the investment return ratio is not high. Compared with the two coatings, the graphene coating has the advantages of obvious mechanical property, thermal property, corrosion resistance and scale prevention, and the service life and the heat transfer efficiency of the heating element are greatly improved.
SUMMERY OF THE UTILITY MODEL
The heating element provided with the graphene coating on the surface is provided to overcome the defects in the prior art.
In order to solve the technical problems, the invention adopts the following solution:
providing a graphene-coated heating element, comprising a heating tube; the heating tube is internally provided with a heating wire, two ends of the heating wire are provided with leading rods, the heating tube is internally filled with insulating fillers, and the outer wall of the heating tube is provided with a graphene coating.

As an improvement, the heating pipe is a straight pipe or a bent pipe.
As a refinement, the graphene coating has a thickness of not less than 20 μm. The graphene coating is prepared from special resin, graphene, auxiliary materials and the like.
The principle of the utility model is that: the heating pipe is provided with a graphene spraying or immersion treatment on the surface of the heating pipe after being conventionally wound, welded by a pin, filled with an insulating medium and bent into a required shape through a series of processes, so that an even graphene coating is formed on the surface of the heating pipe, the scale on the surface of the heating pipe is prevented from accumulating, and heat in the heating pipe is prevented from being incapable of being transferred into water due to the blocking of the scale. The graphene has good anti-corrosion performance and thermodynamic performance, the heat conductivity coefficient of the graphene is as high as 5300W/m.K, the coating thickness is micron-level, the weight is light, and the corrosion resistance and the heat conduction efficiency of the heating pipe are improved.
Compared with the prior art, the beneficial effects of the utility model are that: the heating element with the graphene coating has the advantages that the scale prevention and corrosion prevention performance is better than that of a product without the coating; compared with other coated products, the product with the coating is not easy to damage in the production and transportation processes; the product with the graphene coating has higher heat conduction efficiency than products with other coatings.
