[0002] Hot pot and spicy hotpot are a popular Chinese dish enjoyed by people across my country. However, because hot pot and spicy hotpot require fire and a hot pot, it is only suitable for dine-in dining. However, with the changes in modern lifestyles, people have developed a demand for hot pot and spicy hotpot meals as fast food, which has led to the emergence of self-heating hot pots in the existing technology. However, due to limited energy consumption, existing self-heating hot pots cannot cook a large amount of ingredients in one pot through self-heating. Therefore, they are usually large in size and the amount of ingredients packaged is small, which cannot meet the appetite requirements of most people. Therefore, existing self-heating hot pots need to be structurally improved to increase thermal energy utilization or to achieve the demand for prefabricated and fast food hot pot by changing the bowls, buckets, pots, tableware, and the preparation, packaging, and consumption methods of ingredients. In order to overcome the shortcomings of the existing technology, the utility model proposes a technical solution of an auxiliary heating device for preparing cooked soups, dishes and pre-prepared ingredients for boiling and eating. The utility model changes the cooked pre-prepared ingredients represented by cooked hot pot and spicy hot pot into convenient fast food pre-prepared products that can be boiled and eaten with boiling water, and can be heated thoroughly and meet sufficient hot food needs without the intervention of electric fire. By changing the bowls, buckets, pots, tableware and the production, packaging and eating methods of ingredients, the hot pot and spicy hot pot cooked ingredients can be quickly eaten as hot soups, and the cooked dumplings and wontons wrapped in dough can be eaten as soups. The tableware with an auxiliary heater and the cooked hot pot and spicy hot pot or the cooked dumplings and wontons wrapped in dough are packaged together to form a fast food product that can be circulated in the market and eaten in sufficient quantities.
