[0020] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] As Figures 1 to 6As shown in the figure, the present utility model provides a heating pack for a self-heating pot and a packaging box using the heating pack. The heating pack includes a heating tray 3, a heating module 4, and a water bag 5. A water bag incision 51 is provided on the left side of the water bag 5, and a tray incision 31 is provided on the right side of the heating tray 3. The front end of the drawstring 8 is located outside the right side of the top surface of the water bag 5. After extending leftward, the drawstring 8 passes downward through the water bag incision 51, then extends rightward to the tray incision 31 and passes downward, and is knotted at the end of the drawstring 8 to fix the heating tray 3. The bottom surface of the water bag 5 and the top surface of the heating tray 3 are connected and fixed. The packaging box includes a bowl body 1 and a bowl cover 2. Above the heating pack, there are a rice bowl 6 and a side dish bowl 7. Pulling the top end of the drawstring 8 outward by hand, the middle area on the left side of the drawstring 8 moves rightward to cut and break the water bag incision 51, causing the water inside to flow out and contact the heating module 4, quickly releasing heat and water vapor to heat the rice bowl 6 and the side dish bowl 7 above.

[0022] In the above solution, the water bag 5 is connected to the top surface of the heating tray 3 by ultrasonic welding.

[0023] Among them, a lifting ear 9 is connected to the top end of the drawstring 8.

[0024] In addition, the water bag 5 is formed by thermally fusing two upper and lower plastic bags, and the water is sealed inside.

[0025] Specifically, the outer contour shape of the combined rice bowl 6 and side dish bowl 7 is adapted to the inner cavity contour of the bowl body 1.

[0026] Furthermore, a fresh-keeping film is hermetically connected to the top surfaces of the rice bowl 6 and the side dish bowl 7.

[0027] In the present utility model, the product is composed of a main bowl (bowl body 1, bowl cover 2); an edible module (rice bowl 6, side dish bowl 7); a heating module (heating tray 3, heating module 4, water bag 5, drawstring 8 with a lifting ear 9).

[0028] The bowl body 1 and the bowl cover 2 are combined in an inward buckling manner; the combined whole of the edible module (rice bowl 6, side dish bowl 7) fits the size of the bowl body 1 and is placed on the protruding platform of the bowl body 1; the heating module is placed at the bottom of the main bowl 1; the heating plate 4 in the heating module is placed in the heating tray 3, and the water bag 5 and the heating tray 3 are fixed by ultrasonic welding.

[0029] A punching incision is made on one side of the heating tray 3, the drawstring 8 is fixed by tying a knot, and then the drawstring 8 is wound back above the water bag through the bottom of the water bag 5; a lifting ear 9 is connected to the end of the drawstring 8 to facilitate pulling the drawstring 8.

[0030] The present utility model integrates the heating module, and the heating module 4 and the water bag 5 are integrally arranged inside the heating tray 3.

[0031] Pull the drawstring 8 to cut open the water bag 5, so that the water contacts the heating material, and the heating operation is completed in one step.

[0032] Integrate the food heating module with the food; the food can be heated through the heating module; the container for holding the food is sealed to prevent the steam generated during heating from directly contacting the food, making it safer and healthier.

[0033] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the invention. Any simple modification, equivalent change or modification made to the above embodiments based on the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
