[0028] Example 1

[0029] like Figure 1-3 As shown, this embodiment provides a heat therapy patch with temperature regulation function, including a heating pack 1, the upper surface of the heating pack 1 is covered with a plastic film, the lower surface of the heating pack 1 is covered with release paper, a ventilation valve is provided through the plastic film, and the ventilation valve includes an upper cover 3 and a lower cover 4.

[0030] The heating pack 1 includes a breathable film and a heating material, and the heating material is wrapped inside the breathable film. The upper breathable film is covered with a plastic film, and the release paper is attached to the lower breathable film by gluing. The plastic film is made of flexible materials such as nylon, polyethylene, and polyvinyl chloride, so that the thermal therapy patch can be flatly fixed on the surface of the human body or human clothing, and the user's movement during use does not affect the opening and closing of the ventilation valve.

[0031] The plastic film has a hole in the middle, and the hole in the plastic film is bonded to the edge of the lower cover 4.
