Description

Technical Field

[0001] This utility model relates to the field of heat patch technology, specifically to a heat patch with controllable temperature. Background Technology

[0002] Traditional heat packs consist of two parts: an outer vacuum-sealed bag and the heat pack itself containing the heating material. The heat pack is sealed inside the vacuum-sealed bag, effectively isolating it from external oxygen and ensuring safe storage. Once the outer bag is opened, the heating material inside releases warmth steadily and continuously for 12 to 20 hours, catalyzed by oxygen and moisture in the air, creating a comfortable heating experience. However, traditional heat packs have the following problems: after being removed from the outer bag, the heat pack is completely exposed to the air, making it difficult to control the amount of contact with air. Users can only passively receive the heat provided by the heat pack, and when the temperature rises to a high level, it may cause a burning sensation on the user's skin, leading to strong discomfort and greatly affecting the comfort and safety of use. Utility Model Content

[0003] This invention addresses the problem that when the main body of a heat patch is completely exposed to the air during use, making it difficult to control the heat generated by the heat patch itself. It provides a heat patch with controllable temperature, which improves the comfort and safety of the heat patch.

[0004] To solve the above problems, the technical solution of this utility model is:

[0005] A temperature-controllable heat patch includes a heat patch body, a release paper on the rear side of the heat patch body, the release paper being connected to the heat patch body via an adhesive layer, and a control component. The control component includes a barrier sheet and a sealing zipper. The edge of the barrier sheet is fixedly connected to the front side of the heat patch body. The space between the barrier sheet and the heat patch body is an air intake chamber. A connecting bag is provided on the barrier sheet. The connecting bag is a rectangular bag with openings at both the front and rear ends. The rear opening of the connecting bag passes through the fixed barrier sheet and communicates with the air intake chamber. A sealing zipper is provided at the front opening of the connecting bag, and the sealing zipper has a pull tab for closing or opening the sealing zipper.

[0006] Furthermore, the barrier sheet is a sheet made of PVC material, and the connecting bag is a rectangular bag made of PVC material.

[0007] Furthermore, the barrier sheet is provided with multiple control elements spaced apart from left to right.

[0008] Furthermore, the barrier sheet is provided with an air inlet corresponding to the rear end of each connecting bag. The air inlet is opened along the height direction of the barrier sheet and penetrates the front and rear sides of the barrier sheet.

[0009] Furthermore, the rear end of the outer side of each of the connecting bags is fixedly connected to the sidewall of the air inlet.

[0010] Furthermore, the heat patch body includes a non-woven fabric layer and a heating element. There are two non-woven fabric layers, and the edges of the two non-woven fabric layers are fixedly connected. The heating element is filled in the cavity between the two non-woven fabric layers. The barrier sheet is connected to the non-woven fabric layer on the front side of the heat patch body, and the connection point between the edge of the barrier sheet and the heat patch body is located on the outer periphery of the heating element.

[0011] The beneficial effects of this utility model through the above technical solution are as follows:

[0012] In the process of using the heat patch, this utility model controls the size of the opening of the sealing zipper on one or more control components, controls the size of the front opening of the connecting bag connected by the sealing zipper, and thus controls the air intake of the air intake chamber. By controlling the amount of air intake, the amount of contact between the heating element and the air can be controlled, thereby controlling the temperature of the heating element and improving the comfort and safety of the heat patch.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1-5As shown, a temperature-controllable heat patch includes a heat patch body 1. A release paper 3 is provided on the rear side of the heat patch body 1. The release paper 3 is connected to the heat patch body 1 via an adhesive layer 2. The rear side of the heat patch body 1 faces the human skin. The heat patch body 1 also includes a control component, which includes a barrier sheet 4 and a sealing zipper 5. The barrier sheet 4 is a rectangular sheet. The edge of the barrier sheet 4 is fixedly connected to the front side of the heat patch body 1. The outer side of the heat patch body 1 is the side opposite to the rear side of the heat patch body 1. The space between the barrier sheet 4 and the heat patch body 1 is an air intake chamber 9. A connecting bag 6 is provided on the barrier sheet 4. The connecting bag 6 is a rectangular bag with openings at both the front and rear ends. The rear opening of the connecting bag 6 passes through and fixes the barrier sheet 4, and communicates with the air intake chamber 9. A sealing zipper 5 is provided at the front opening of the connecting bag 6. The sealing zipper 5 has a pull tab 7 for closing or opening the sealing zipper 5.

[0021] The barrier sheet 4 is a sheet made of PVC material, and the connecting bag 6 is a rectangular bag made of PVC material.

[0022] The barrier plate 4 is provided with multiple control elements spaced apart from left to right.

[0023] The barrier plate 4 is provided with an air inlet 8 that corresponds to the rear end of each connecting bag 6. The air inlet 8 is opened along the height direction of the barrier plate 4 and penetrates the front and rear sides of the barrier plate 4. The air inlet 8 is an elongated hole.

[0024] The rear end of the outer side of each of the connecting bags 6 is fixedly connected to the side wall of the air inlet 8.

[0025] The heat patch body 1 includes a non-woven fabric layer 1b and a heating element 1a. There are two non-woven fabric layers 1b, and their edges are fixedly connected. The heating element 1a is filled in the cavity between the two non-woven fabric layers 1b. The barrier sheet 4 is connected to the non-woven fabric layer 1b on the front side of the heat patch body 1, and the edge of the barrier sheet 4 is connected to the heat patch body 1 at the outer periphery of the heating element 1a.

[0026] In the initial state, the sealing zipper 5 on each control component is in a closed and sealed state, and no air enters the air intake chamber 9;

[0027] In use, remove the release paper 3, and attach the heat patch body 1 to clothing via the adhesive layer 2. Pull the zipper 7 on one or more control components to open the sealing zipper 5. The front opening of the connecting bag 6 connected to the sealing zipper 5 will open. By controlling the distance the zipper 7 moves, the size of the opening of the sealing zipper 5 can be controlled, thereby controlling the size of the opening of the front opening of the connecting bag 6 connected to the sealing zipper 5, and thus controlling the air intake of the air intake chamber 9. The air in the air intake chamber 9 comes into contact with the heating element 1a through the non-woven fabric layer 1b on the front side of the heat patch body 1. The heating element 1a generates heat, and the heat is used to warm the human body through the non-woven fabric layer 1b on the rear side. When it is necessary to lower the temperature of the heating element 1a, pull the zipper 7 to control the front opening of the connecting bag 6 to become smaller or close the front opening of the connecting bag 6, thereby reducing or closing the air intake of the air intake chamber 9. Therefore, this utility model can control the amount of air entering the air intake chamber 9 through the control components, and control the temperature of the heating element 1a.
