Figure 2 As shown, Figure 2 The circle indicated by the number 4 in the figure indicates the sewing line, so that the connection method of the heating wire 2 is very simple, convenient, and firmly connected. However, the connection method of the heating wire 2 and the elastic cloth 1 is not limited to this. For example, the heating wire 2 can also be set on the elastic cloth 1 in an encapsulated manner: Figure 3 As shown, the elastic fabric 1 has a multi-layer structure, and the heating wire 2 is encapsulated between two adjacent layers of the elastic fabric 1. Furthermore, the two adjacent layers of the elastic fabric 1 are bonded together using an elastic hot-melt adhesive film 5 to position the heating wire 2. Alternatively, the two adjacent layers of the elastic fabric 1 can be sewn together.

[0037] The heating wire 2 may or may not be insulated, and may be one or more. This embodiment uses one heating wire as an example. The heating wire 2 is fixed to the elastic fabric 1 in a convoluted configuration, with both ends of the heating wire 2 extending from the same edge of the elastic fabric 1. Alternatively, the heating wire 2 may be fixed to the elastic fabric 1 in a non-convoluted configuration, in which case the ends of the heating wire 2 may extend from different edges of the elastic fabric.

[0038] The non-elastic member 3 can be attached to the elastic fabric 1 by at least one of sewing, gluing, snap fastening, and screwing. Specifically, the non-elastic member 3 is sheet-shaped and can be made of, but is not limited to, non-elastic fabric or non-elastic decorative film. The non-elastic member 3 can be a single-layer structure or a multi-layer structure.

[0039] In this embodiment, the non-elastic member 3 is connected to the edge of the elastic fabric 1. There are multiple non-elastic members 3, and the multiple non-elastic members 3 are distributed along the periphery of the elastic fabric 1. However, this is not limiting. In other embodiments, there is only one non-elastic member 3, and it is disposed along the periphery of the elastic fabric 1. The non-elastic member 3 has a circular outline, but this is not limiting. In other embodiments, the non-elastic member 3 may also have a polygonal or elliptical outline.

[0040] In this embodiment, the non-elastic member 3 includes an upper structure and a lower structure, and the upper structure and the lower structure are respectively bonded to the upper and lower surfaces of the elastic fabric 1. Figure 3 In addition, a positioning hole 31 is provided on the non-elastic member 3, and the positioning hole 31 is through-through from top to bottom and passes through the elastic cloth 1, as shown in FIG. Figure 3 When the portion of the non-elastic member 3 where the positioning hole 31 is provided does not overlap with the elastic fabric 1 , the positioning hole 31 may not penetrate the elastic fabric 1 .

[0041] In this embodiment, the four sides of the elastic cloth 1 are rectangular, and the non-elastic parts 3 are respectively provided at the four corners. The shape of the four sides of the elastic cloth 1 is not limited to a rectangle. In other embodiments, the four sides of the elastic cloth 1 are in other shapes, such as a circle, an ellipse, a trapezoid, etc. Figure 4 As shown, the elastic cloth 1 has a circular outline, and a plurality of non-elastic parts 3 are evenly distributed on its edges. Figure 5 As shown, the four sides of the elastic cloth 1 are in the shape of a pattern, and non-elastic parts 3 are respectively provided at the four corners.

In addition, the utility model can also be applied to massage products, such as massage machines with kneading functions, such as Figure 7As shown, the massage movement includes a fixing unit 7, a driving unit, and two left and right massage heads 6. The driving unit is installed on the fixing unit 7, and the driving unit is connected to the two massage heads 6 to drive the two massage heads 6 to move and realize the kneading button. The two massage heads 6 are connected together using the elastic heating sheet of the utility model. Specifically, each massage head has a massage head body 61 and two massage parts 62 distributed front and back. The two massage parts 62 are respectively connected to the massage head body 61. The elastic heating sheet of the utility model has four non-elastic parts 3, corresponding to the four massage parts 62. The connection between the massage parts 62 and the massage head body 61 is avoided by the positioning holes 31 provided on the corresponding non-elastic parts 3. At the same time, the massage parts 7 and the massage head body 6 clamp the non-elastic parts 3 on the elastic cloth 1 from top to bottom. This massage movement with the elastic heating sheet of the utility model can use the elastic cloth 1 to support the human body parts, improving the human body massage experience. At the same time, it can use the heat generated by the heating wires 2 on the elastic cloth 1 to provide a hot compress to the human body parts, thereby improving the massage effect of the massage movement.
