Wherein:

[0019] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the following detailed description of the specific implementation of the utility model is combined with the drawing of the specification.
[0020] Refer to Figure 1 For an embodiment of the utility model, a kind of armor carbon fiber heating wire is provided, this armor carbon fiber heating wire includes line body 1, line body 1 outside is provided with flame-retardant layer 2, flame-retardant layer 2 outside is provided with insulating layer 3, insulating layer 3 outside is provided with fastening layer 4, fastening layer 4 outside is provided with outer layer 5, outer layer 5 outside is provided with armor layer 6.
[0021] Specifically, line body 1 adopts carbon fiber heating wire, carbon fiber heating wire has the characteristics of fast heat conduction speed, energy saving, further, the number of line body 1 is multiple, so it has higher heat, further, multiple line body 1 is spirally wound together, so it can increase the firmness of line body 1, and simultaneously can make the heat of line body 1 more concentrated.
[0022] Specifically, flame-retardant layer 2 adopts inorganic flame-retardant material, organic flame-retardant material or environment-friendly flame-retardant material;Inorganic flame-retardant material is like: diantimony trioxide, aluminium hydroxide and silica gel etc.;Organic flame-retardant material is like: organic halide, organic phosphide and triazo etc.;Environment-friendly flame-retardant material is like: unsaturated resin flame retardant, silica gel flame retardant, rubber flame retardant, polyamide flame retardant, PE flame retardant, PP flame retardant, PVC flame retardant etc.
[0023] Note that the antimony trioxide needs to be used in cooperation with organic flame retardant materials; the aluminum hydroxide needs to be used in large amounts; and melamine is often used in PA and PU.
[0024] Specifically, a plurality of circumferentially distributed line grooves are formed in the flame-retardant layer 2, and one or more line bodies 1 are arranged in each line groove. It should be noted that the line grooves do not penetrate the flame-retardant layer 2. The main function of the flame-retardant layer 2 is to prevent the fire source from leaking out when the line body short-circuits and catches fire, thereby improving the safety of the armored carbon fiber heating wire. Further, a protrusion higher than the line body 1 is arranged between adjacent line grooves. The protrusion also has flame-retardant properties. The line body 1 arranged in the line groove is separately isolated. When the line body 1 in a line groove short-circuits and catches fire, the protrusions on both sides of the line groove can block the line body 1 that short-circuits and catches fire in the line groove, thereby preventing the spread of sparks and further improving the safety of the armored carbon fiber heating wire. The flame-retardant layer 2 has good toughness, which ensures that the armored carbon fiber heating wire can be bent as needed during use.
[0025] Specifically, the insulating layer 3 is made of a high-temperature-resistant insulating material, such as high-temperature-resistant nylon, polytetrafluoroethylene, polyether ether ketone, general plastic (PP and PVC, etc.). Further, the inner side of the insulating layer 3 is painted with a flame-retardant material to form an outer flame-retardant layer, achieving a double flame-retardant effect. The insulating layer 3 has good toughness, which ensures that the armored carbon fiber heating wire can be bent as needed during use.
[0026] Specifically, the fastening layer 4 is made of a plastic material, and at the same time, the fastening layer 4 has insulating properties. Preferably, the fastening layer 4 is made of nylon or plastic. The fastening layer 4 is arranged as a fastening coil tightly wound on the outer surface of the insulating layer 3. Further, the fastening coil is wound in parallel with the circular cross-section of the insulating layer 3 or spirally wound on the outer surface of the insulating layer 3. Further, the outer surface of the insulating layer 3 is provided with a shallow groove for accommodating the fastening coil, and the inner surface of the outer layer 5 is provided with a groove for clamping the fastening coil. This structure not only makes the fastening layer 4 more tightly arranged, but also further improves the insulating performance of the armored carbon fiber heating wire.
[0027] Specifically, the outer layer 5 is made of a silica gel tube or a rubber tube. Silica gel and rubber materials have good insulating and thermal conductivity properties. The thickness of the outer layer 5 needs to be greater than the diameters of the other layers. Further, the thickness of the outer layer 5 needs to be greater than the sum of the diameters of the other layers. This can improve the overall strength of the armored carbon fiber heating wire. However, at the same time, the outer layer 5 needs to have good toughness and plasticity to ensure that the armored carbon fiber heating wire can be bent as needed during use. The outer layer 5 tightly presses the layers inside it, thereby tightly connecting the adjacent layers.
[0028] Specifically, the armor layer 6 adopts a metal material, the armor layer 6 needs to have good wear resistance and corrosion resistance, and a metal material after electroplating process can be selected, further, the armor layer 6 selects an armored steel wire mesh, that is, the armor layer 6 is composed of two interlaced metal wires, the two metal wires are alternately woven one above the other, forming a mesh structure, the armor layer 6 uses a metal material with good toughness and high strength, so that the armor carbon fiber heating wire can be bent as required during use, but the armor layer 6 will not be damaged or broken.
[0029] Specifically, each layer needs to have good toughness to ensure that the heating wire can be bent.
[0030] During use, the wire body 1 is installed in the flame-retardant layer 2, and then the insulating layer 3 is tightly sleeved outside the flame-retardant layer 2 to achieve heat conduction and insulation of the wire body 1, then the fastening material is wound on the insulating layer 3 to form the fastening layer 4 to achieve sealing and secondary insulation, then the outer layer 5 is sleeved outside the fastening layer 4 to achieve further insulation, and finally the armor layer 6 is connected on the outer layer 5, so that the whole heating wire has good heat conductivity and safety.

Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced without departing from the spirit and scope of the present application, and all should be covered in the scope of the claims of the present application.
