[0040] As attached Figure 1-3 As shown, the utility model also provides a graphene heating unit, which can be used alone as a heating pad, and can be used for heating in the fields of indoor / outdoor heating, functional fabrics, agricultural insulation, industrial equipment, etc., including a graphene heating layer 1 and a fabric layer 2 covering both sides of the graphene heating layer 1, and the fabric layer 2 is used to physically protect the graphene heating layer 1 and isolate the graphene heating layer 1 from the bonding part to be heated;

[0041] The graphene heating layer 1 includes a graphene fabric layer 11 and a cable heating element 12, wherein the cable heating element 12 includes a resistance wire 121 and a graphene cable sheath 122 wrapped outside the resistance wire 121.

[0042] The graphene heating unit provided by the utility model has the effects of being flat and comfortable, having a fast heating speed, having a uniform temperature and having a high heat conversion efficiency, and can provide a better heating effect under the same energy consumption.

[0043] In one of the embodiments, the cable heating element 12 is any one of a U-shaped, serpentine or disc-shaped shape or a combination of more than two. Such a configuration can improve the temperature uniformity effect. Specifically, the cable heating element 12 can be laid out in one piece, or it can be composed of multiple pieces connected in series or in parallel. The specific connection method is the existing technology and is not limited here. In this embodiment, the interlocking groove 111 is a groove body of a corresponding U-shaped, serpentine or disc-shaped shape or a combination of more than two, that is, the cable heating element 12 and the interlocking groove 111 are interlocked with each other to form a flat plane, so that the entire plane of the graphene heating layer 1 has a uniform heating effect.

[0044] In one embodiment, the embedding groove 111 is a through groove or a groove. Preferably, the graphene fabric layer 11 is composed of multiple layers of graphene fabric stacked together, and each layer of graphene fabric is provided with slot holes, and multiple slot holes are stacked to form the embedding groove 111.

[0045] In one of the embodiments, a breathable inner layer 3 is provided between at least one of the graphene heating layers 1 and the fabric layer 2, thereby improving the breathability and heat permeability effects.

[0046] In one of the embodiments, the fabric layer 2 and the graphene fabric layer 11 are edge-sealed at the periphery, thereby improving the overall structural stability of the graphene heating unit.

[0047] Reference Figure 4-Attached Fig.11 The utility model also provides a graphene heating combination pad, including a male unit 4 and a female unit 5, the male unit 4 and the female unit 5 can be detachably connected, and the heating area of ​​the heating unit can be customized, which greatly improves the applicability of the graphene heating unit;

Thus, there is no need for each graphene heating unit to be electrically connected to a power source, thereby simplifying the circuit connection structure.

[0051] In one embodiment, the male connection structure 41 includes a first convex fabric layer 411 protruding from the side of the graphene heating unit. Preferably, the first convex fabric layer 411 is formed by extending two fabric layers 2 after edge sealing, and the extended parts are sewn together to form a whole. One side of the first convex fabric layer 411 is provided with a first Velcro mother patch 412, and the other side is provided with a first Velcro sub-patch 413;

[0052] The female connection structure 51 includes a second outer convex fabric layer 511 protruding from the upper and lower ends of the side of the graphene heating unit. Preferably, the second outer convex fabric layer 511 is also formed by extending the two fabric surface layers 2 after edge sealing. A receiving cavity 514 is formed between the two second outer convex fabric layers 511. A second Velcro mother patch 512 is arranged on the inner side of one of the second outer convex fabric layers 511, and a second Velcro sub-patch 513 is arranged on the inner side of the other second outer convex fabric layer 511.

[0053] When the male unit 4 and the female unit 5 cooperate, the first outer convex fabric layer 411 is embedded in the accommodating cavity 514, and the first Velcro mother patch 412 cooperates with the second Velcro sub-patch 513, and the first Velcro sub-patch 413 cooperates with the second Velcro mother patch 512. In this embodiment, the male unit 4 and the female unit 5 can be easily connected to each other flexibly, and the connection stability is high. After the connection, the male unit 4 and the female unit 5 can both be deformed to adapt to the curved surface or the heterogeneous surface to be heated. In addition, when the female unit 5 is used, transported or stored alone, the second Velcro mother patch 512 and the second Velcro sub-patch 513 can fit each other. On the one hand, the two second outer convex fabric layers 511 can be avoided from flanging, and on the other hand, the second connecting plug 52 can be protected.

[0054] In one of the embodiments, when the male unit 4 and the female unit 5 are matched, the outer sides of the two second convex fabric layers 511 are flush with the end faces of the graphene heating units of the male unit 4 and the female unit 5, that is, when the male unit 4 and the female unit 5 are matched, the front and back end faces of the male unit 4 and the female unit 5 are flat, without any protrusions or groove structures, thereby ensuring flatness and comfort for use by humans or animals.

[0055] In one of the embodiments, the first connecting plug 42 and the second connecting plug 52 are connected in the accommodating cavity 514. Such a configuration allows the first connecting plug 42 and the second connecting plug 52 to be protected in the closed accommodating cavity 514. On the one hand, loosening of the connection between the first connecting plug 42 and the second connecting plug 52 can be avoided, and on the other hand, the connection structure can be physically protected.

[0056] In one embodiment, the male unit 4 and the female unit 5 are both rectangular structures; the male unit 4 is provided with the male connection structure 41 and the first connection plug 42 around it; the female unit 5 is provided with the female connection structure 51 and the second connection plug 52 around it.

Specifically, one male unit 4 is connected to four female units 5 on all sides, and one female unit 5 is connected to four male units 4 on all sides. In this embodiment, the length direction dimension of the first convex fabric layer 411 of the male unit 4 is smaller than the end face dimension of the graphene heating unit, so that the first convex fabric layers 411 of the male unit 4 on the adjacent two side walls of the female unit 5 will not interfere with each other, ensuring the overall flatness.
