Description

Technical Field

[0001] This utility model relates to the field of heating patch technology, specifically to a heating patch for a fall prevention bag. Background Technology

[0002] Heating patches are topical medications that relieve physical discomfort through physical heating. They are primarily used to alleviate pain caused by various cold-related ailments, such as arthritis and frozen shoulder. Additionally, they are widely used for menstrual cramps and lower back pain in women.

[0003] Currently used heating pads are filled with heating powder, which generates heat when it comes into contact with air and moisture. However, because the heating powder is in powder or granular form, it may accumulate after being filled into the heating pad. The accumulated heating powder generates a lot of heat, which may pose a risk of burns to the user. Summary of the Invention

[0004] This invention addresses the problem of uneven heat generation caused by the accumulation of powdered heating material in heating pads by providing a fall-proof heating pad that prevents the accumulation of heating material, avoids concentrated heating, and improves safety during use.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A heating patch for preventing falls includes a non-woven fabric layer one, a non-woven fabric layer two, and a breathable insulating layer. The rear edge of the non-woven fabric layer one is fixedly connected to the front edge of the non-woven fabric layer two. The cavity between the non-woven fabric layer one and the non-woven fabric layer two is a receiving cavity. The breathable insulating layer is disposed in the receiving cavity and is corrugated. The upper and lower ends of the breathable insulating layer are respectively connected to the upper and lower ends of the rear side of the receiving cavity. The troughs of the breathable insulating layer are fixedly connected to the rear side of the receiving cavity, and the crests of the breathable insulating layer are fixedly connected to the front side of the receiving cavity. The breathable insulating layer and the non-woven fabric layer one constituting the receiving cavity form multiple filling cavities one, and the breathable insulating layer and the non-woven fabric layer two constituting the receiving cavity form multiple filling cavities two. Both the filling cavities one and the filling cavities two are filled with heating material.

[0007] Furthermore, the front edge of the nonwoven fabric layer is provided with release paper, which is connected to the front edge of the nonwoven fabric layer by an adhesive layer. The release paper is □-shaped and located outside the receiving cavity.

[0008] Furthermore, the side edge of the first nonwoven fabric layer is flush with the side edge of the second nonwoven fabric layer; when the first and second nonwoven fabric layers are in their natural state, the projected area of ​​the first nonwoven fabric layer on the vertical plane is greater than the projected area of ​​the second nonwoven fabric layer on the vertical plane.

[0009] Furthermore, the distance between the left and right ends of the breathable partition corresponds to the distance between the left and right ends of the receiving cavity.

[0010] Furthermore, the breathable interlayer is a sheet made of polyester fiber material.

[0011] Furthermore, the peaks of the breathable barrier face the front side of the receiving cavity, the troughs of the breathable barrier face the rear side of the receiving cavity, and both the upper and lower ends of the breathable barrier are troughs of the breathable barrier.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] When this utility model is used, because the receiving cavity is provided with a breathable partition, the breathable partition divides the receiving cavity into a non-connected filling cavity one and a filling cavity two. The heating material is placed in the filling cavity one and the filling cavity two, which can ensure that the heating material is evenly distributed in the receiving cavity, thereby ensuring uniform heating and improving the safety of use.

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

[0020] like Figures 1-4As shown, a fall-prevention bag heating patch includes a non-woven fabric layer 1, a non-woven fabric layer 2, and a breathable insulating layer 3. The non-woven fabric layer 1 and the non-woven fabric layer 2 are rectangular sheets of the same shape. The rear edge of the non-woven fabric layer 1 is fixedly connected to the front edge of the non-woven fabric layer 2. The cavity between the non-woven fabric layer 1 and the non-woven fabric layer 2 is a receiving cavity. The breathable insulating layer 3 is disposed within the receiving cavity and is corrugated. The upper and lower ends of the breathable insulating layer 3 are respectively connected to the upper and lower ends of the rear side of the receiving cavity. The corrugation of the breathable insulating layer 3... The valleys of the breathable partition 3 are fixedly connected to form the rear side of the receiving cavity. The connection between the valleys of the breathable partition 3 and the rear side of the receiving cavity is a heat-fused connection. The peaks of the breathable partition 3 are fixedly connected to the front side of the receiving cavity. The connection between the peaks of the breathable partition 3 and the front side of the receiving cavity is a heat-fused connection. The breathable partition 3 and the non-woven fabric layer 1 forming the receiving cavity form multiple filling cavities 4. The breathable partition 3 and the non-woven fabric layer 2 forming the receiving cavity form multiple filling cavities 5. The filling cavities 4 and 5 are filled with heating material 6.

[0021] The front edge of the nonwoven fabric layer 1 is provided with release paper 7, which is connected to the front edge of the nonwoven fabric layer 1 by adhesive layer 8. The release paper 7 is □-shaped and located outside the receiving cavity.

[0022] The side edge of the nonwoven fabric layer 1 is flush with the side edge of the nonwoven fabric layer 2; when the nonwoven fabric layer 1 and the nonwoven fabric layer 2 are in their natural state, the projected area of ​​the nonwoven fabric layer 1 on the vertical plane is greater than the projected area of ​​the nonwoven fabric layer 2 on the vertical plane.

[0023] The distance between the left and right ends of the breathable partition 3 corresponds to the distance between the left and right ends of the receiving cavity.

[0024] The breathable interlayer 3 is a sheet made of polyester fiber material.

[0025] The peaks of the breathable barrier 3 face the front side of the receiving cavity, and the troughs of the breathable barrier 3 face the rear side of the receiving cavity. Both the upper and lower ends of the breathable barrier 3 are troughs of the breathable barrier.

[0026] In use, multiple filling cavities 4 are formed between the breathable partition 3 and the non-woven fabric layer 1 that constitutes the receiving cavity, and multiple filling cavities 5 are formed between the breathable partition 3 and the non-woven fabric layer 2 that constitutes the receiving cavity. Both filling cavities 4 and 5 are filled with heating material 6. The heating material 6 is supported by the breathable partition 3 and separated in the non-connected filling cavities 4 and 5. Therefore, the heating material 6 in the upper part will not move downward during transportation or use, avoiding accumulation of heating material and ensuring that the heating material 6 is evenly distributed in the receiving cavity, thereby ensuring uniform heating and improving the safety of the heating patch.
