This creative department provides a heart-shaped heating patch, which includes a non-woven fabric layer, and a breathable layer is bonded and fixed on the inner side of the non-woven fabric layer. A raw material layer is adhered and fixed on the inner side of the breathable layer, and a heating layer is provided inside the raw material layer. The utility model is novel in use, novel in design and simple in structure. It brings the gospel to the majority of users in winter, and it is adhered to the socks. It is fixed by the magic tape, which increases the stability effect and prevents the heart-shaped heating paste from sticking due to walking. The problem of running around everywhere effectively improves the comfort of use. After the air enters, it will oxidize with iron powder to generate iron oxide. When iron powder is corroded, it will release heat, thereby achieving self-heating effect. Slow heat dissipation, used for thermal insulation, can extend the heating time of the heart-shaped heating paste, which increases the practicality. The raw material layer can be placed in different medicine bags according to the needs, so that it can add additional effects when used in different parts.本創作係提供一種心型發熱貼，包括無紡布層，所述無紡布層的內側黏合固定有透氣層，且無紡布層的外表面位於兩個端部位置處縫合有魔術貼，所述透氣層的內側黏合固定有原料層，所述原料層的內部設置有加熱層。本使用新型，設計新穎，結構簡單，在冬天為廣大使用者帶來福音，將其粘附在襪子上，通過魔術貼進行固定，增加了穩固效果，避免因走動導致心型加熱貼粘附不牢到處亂跑的問題，有效的提高了使用舒適度，空氣進入後與鐵粉產生氧化反應生成氧化鐵，鐵粉被腐蝕時會釋放熱量，從而起到自加熱的效果，鵝暖石吸熱快，散熱慢，用於保溫，可以延長心型加熱貼的發熱時間，增加了實用性，原料層可視需求再放入不同的藥包，這樣使用於不同部位時，可以增加額外的功效。
