[0021] The following detailed description of the application in conjunction with the drawings, it is necessary to point out here that the following detailed description is only used to further illustrate the application, and cannot be understood as limiting the scope of the application, and those skilled in the art can make some non-essential improvements and adjustments to the application according to the above application content.
[0022] Example 1
[0023] As Figure 1 - Figure 3As shown, the modular cuttable graphene defogging film comprises a base layer 1 and a graphene heating layer 11 arranged on the base layer 1, the base layer 1 has a plurality of quantities, a second protective layer 13 is arranged between the graphene heating layer 11 and the base layer 1, and a first protective layer 12 is arranged on the upper surface of the graphene heating layer 11, the first protective layer 12 and the second protective layer 13 are both transparent and heat-conducting materials; further comprising a connecting edge 4 fixedly arranged between adjacent base layers 1, and a rubber edge 3 fixedly arranged at the edge of the base layer 1, each base layer 1 cooperates with the graphene heating layer 11, the first protective layer 12 and the second protective layer 13 and the rubber edge 3 to form a graphene defogging film module, and adjacent graphene defogging film modules are connected through the connecting edge 4.
[0024] As shown in Figure 1 , the first wire 2 is arranged on one side of the base layer 1, and the second wire 21 is arranged on one side of the adjacent base layer 1, the second wire 21 and the first wire 2 are located on the same side of the base layer 1, and the second wire 21 and the first wire 2 are respectively provided with a matching male connector and a female connector, by arranging the first wire 2 and the second wire 21 on the same side of the base layer 1, the connection between the first wire 2 and the second wire 21 between different base layers 1 is facilitated, by arranging the male connector and the female connector, a plurality of graphene defogging film modules are connected in series, the connection stability of the first wire 2 and the second wire 21 is improved, and separation is facilitated.
[0025] As shown in Figure 1 , a plurality of graphene coating strips are arranged in the graphene heating layer 11, and the two ends of the graphene coating strips are connected with the first wire 2 and the second wire 21 through wires, and the graphene coating strips are arranged in a meandering and winding manner, which makes the heating more uniform.
[0026] As shown in Figure 1 - Figure 2 , the connecting edge 4 is in the shape of an elongated strip, a plurality of holes penetrating the surface of the connecting edge 4 are uniformly arranged on the connecting edge 4, and the holes make it more convenient and labor-saving when cutting.
[0027] As shown in Figure 3 , the highest end of the rubber edge 3 is parallel to the highest end of the first protective layer 12, and the lowest end of the rubber edge 3 is parallel to the lowest end of the base layer 1, so as to form a flat surface as a whole, and the rubber edge 3 can tightly fit the surface of the installation position when in use.
[0028] It should be noted that before use, this modular cutable graphene defogging film is connected to a power source via the first wire 2, and connected to another first wire 2 via a male and female connector via the second wire 21 for electrical transmission. When cutting is required, a cutting device is used to cut along the dotted line formed by the holes on the connecting edge 4. By setting a rubber edge 3, if the cut is accidentally made crooked, the rubber edge 3 will form a certain resistance, making it difficult to cut, thereby avoiding damage to the graphene heating layer 11 during cutting.
[0029] In use, by attaching the first protective layer 12 tightly to the mirror surface that needs to be defogging, the graphene coating strip is heated through electrical transmission, thereby heating the mirror surface and defogging it.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
