The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] Please refer to Figures 1 to 3. Figure 1 is a schematic diagram of the overall structure of this utility model, Figure 2 is a top view of the overall utility model, and Figure 3 is a cross-sectional view of the structure of this utility model along line AA in Figure 2.

[0018] This utility model provides a self-heating hot pot box with a trigger-activated membrane breaking structure, including a base 101 and a trigger-activated membrane breaking assembly. The trigger-activated membrane breaking assembly includes a shell 104, a water storage tank 105, a locking block 106, a locking ring 107, a raised spike ring 108, a placement groove 102, a mounting protrusion 114, a fixing fin 103, a disassembly groove 109, a top cover 111, a sealing strip 110, an inner ring cavity 112, and an exhaust port 113. This solution solves the problems of cumbersome operation and safety hazards of traditional self-heating hot pots, as well as the tendency for water bags to rupture in existing improved packaging. It is understood that, before use, users can first check that all components are intact, then place the heating pack into the placement groove 102, ensuring the heating pack is placed flat without wrinkles, and then place the sealing foil film in the placement groove 102. Above, the heating pack is separated from the food and seasonings. The food and seasonings are then placed inside the outer casing 104 in the space surrounding the water tank 105, taking care not to block the steam flow channel. Next, the top cover 111 is closed, ensuring its lower end is fully embedded in the disassembly groove 109, and that the sealing strip 110 is tightly fitted to the outer casing 104 for a good seal. At this point, the locking block 106 is located in the shallow groove on the inner wall of the locking ring 107. When heating is required, hold the outer casing 104 and the base 101 with both hands and press the outer casing 104 firmly, causing the locking block 106 to slide downwards in the deep groove on the inner wall of the locking ring 107. At this time, the outer casing 104 moves downwards relative to the base 101, and the protruding spike ring 108 moves downwards accordingly, piercing the foil film between the water tank 105 and the placement groove 102. The water tank 105... Water flows into the placement slot 102 under gravity, making full contact with the heating pack and triggering a chemical reaction that generates a large amount of heat and steam. The heat generated is transferred upward through the vent holes on the placement slot 102 to heat the food. The steam circulates within the outer shell 104, ensuring even heating of the food. Excess steam generated during heating is discharged through the one-way exhaust valve on the exhaust port 113. The inner ring cavity 112 acts as a pressure buffer to prevent a sudden large release of steam that could cause danger. After heating is complete, wait a moment for the temperature of the box to drop slightly, then lift the top cover 111 to enjoy the steaming hot pot.

[0019] In this specific embodiment, the outer shell 104 is detachably connected to the base 101 and is located above the base 101; the water storage tank 105 is fixedly connected to the outer shell 104 and is located inside the outer shell 104; the retaining ring 107 is fixedly connected to the base 101 and is located on the upper outer surface of the base 101, and the retaining ring 107 is disposed on the lower outer surface of the outer shell 104; the retaining block 106 is fixedly connected to the outer shell 104 and is located on the lower outer surface of the outer shell 104, and the retaining block 106 is disposed inside the retaining ring 107; the protruding spike ring 108 is fixedly connected to the outer shell 104 and is located below the inner wall of the outer shell 104, and the protruding spike ring 108 is also disposed on the inner wall of the base 101.

[0020] The placement groove 102 is fixedly connected to the base 101 and is located inside the upper part of the base 101. The placement groove 102 is located below the protruding barbed ring 108. The mounting protrusion 114 is detachably connected to the protruding barbed ring 108 and is located below the protruding barbed ring 108. The mounting protrusion 114 is also located above the placement groove 102.

[0021] Secondly, the fixed fin 103 is fixedly connected to the base 101 and is located on the lower outer surface of the base 101.

[0022] Meanwhile, the disassembly groove 109 is fixedly connected to the outer shell 104 and located inside the upper part of the outer shell 104. The top cover 111 is fixedly connected to the outer shell 104 and located above the outer shell 104. The lower end of the top cover 111 is disposed inside the disassembly groove 109. The sealing strip 110 is disposed between the top cover 111 and the outer shell 104, and the sealing strip 110 is also disposed above the disassembly groove 109.

[0023] The inner annular cavity 112 is fixedly connected to the top cover 111 and is located inside and above the top cover 111. The inner annular cavity 112 is located above the sealing strip 110. The exhaust port 113 is fixedly connected to the top cover 111 and is located on the lower outer surface of the top cover 111.

[0024] When using this invention, first check that all components are intact. Then, place the heating pack into the placement slot 102, ensuring it is placed flat without wrinkles. Next, place the sealing foil film on the placement slot 102 to separate the heating pack from the food and seasonings. Then, place the food and seasonings into the space around the water tank 105 inside the outer shell 104, taking care not to block the steam flow channel. After that, close the top cover 111, ensuring the lower end of the top cover 111 is fully embedded in the disassembly slot 109, and ensure the sealing strip 110 is tightly fitted to the outer shell 104 for a good seal. At this time, the locking block 106 is located in the shallow groove on the inner wall of the locking ring 107. When heating is required, hold the outer shell 104 and the base 101 with both hands and press the outer shell 104 firmly, so that the locking block 106 is in the locking ring 107. The heating element slides downwards into the deep groove on the inner wall. At this time, the outer shell 104 moves downwards relative to the base 101, and the protruding spike ring 108 moves downwards accordingly, piercing the foil film between the water storage tank 105 and the placement slot 102. Simultaneously, the mounting protrusion 114 presses down on the foil film, causing it to indent in the middle and increase the rupture area. The water in the water storage tank 105 flows into the placement slot 102 under gravity, making full contact with the heating pack and triggering a chemical reaction that generates a large amount of heat and steam. The generated heat is transferred upwards through the vent holes on the placement slot 102 to heat the food. The steam circulates within the outer shell 104, ensuring even heating of the food. Excess steam generated during heating is discharged through the one-way exhaust valve on the exhaust port 113. The inner ring cavity 112 acts as a pressure buffer to prevent a sudden large-scale release of steam that could cause danger. After heating is complete, wait a moment for the box temperature to drop slightly, then lift the top cover 111 upwards. You can then enjoy a steaming hot pot.

[0025] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
