Description

Technical Field

[0001] This utility model relates to the field of baby tableware technology, and more specifically, to a thermos bowl. Background Technology

[0002] When food is placed in existing bowls, it is easy for the food to cool down due to the ambient temperature, which affects the eating experience, especially for infants. Since infants and young children eat for a long time, they need to have good heat preservation. Some existing heating bowls have problems such as uneven heating, low efficiency, and complex structure. For example, some electric bowls use direct heating, which may cause local overheating of the bowl, resulting in food gelatinization or nutrient loss. At the same time, existing constant temperature bowls are often inconvenient to disassemble and clean, which can easily lead to electric leakage. Therefore, based on the existing problems, a constant temperature bowl with uniform heating, simple structure, and easy-to-use design was developed. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a thermal bowl to solve the problems existing in the above-mentioned background technology.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a heat-insulating bowl, comprising a bowl body and a heating device for heating to keep the bowl body at a constant temperature; the heating device is provided with a receiving groove adapted to the bowl body for accommodating the bowl body; the bowl body can be accommodated in the receiving groove; The heating device has an opening; the heating device is detachably equipped with a heating cover adapted to the opening for covering the receiving groove; the opening is connected to the receiving groove. The heating device is equipped with a heating component for heating; the heating component is located in the receiving groove and can abut against the bowl body.

[0005] Optionally, the heating assembly includes: a flexible electromagnetic component for electromagnetic interaction with the bowl body to heat it, and an electromagnetic drive component for electromagnetically driving the flexible electromagnetic component. The flexible electromagnetic component is located at the bottom of the receiving groove and can abut against the bowl body; the output end of the electromagnetic drive component abuts against the flexible electromagnetic component; the electromagnetic drive component can be electrically connected to the flexible electromagnetic component so that the flexible electromagnetic component generates an electromagnetic field.

[0006] Optionally, the flexible electromagnetic component has a wavy pattern on the side near the bowl body to increase the contact area with the bowl body.

[0007] Optionally, the heating device may also include a power supply module for supplying power; the power supply module may be electrically connected to the electromagnetic drive component.

[0008] Optionally, the bowl body includes an inner shell and an outer shell; The inner shell is fixedly connected to the outer shell; a cavity is provided between the inner shell and the outer shell, and the cavity is in a vacuum state.

[0009] Optionally, the heating device is provided with a snap-fit ​​part in a ring shape; the edge of the bowl is provided with a snap-fit ​​groove that matches the snap-fit ​​part; the snap-fit ​​groove can snap into the snap-fit ​​part so that the bowl and the heating device remain relatively stationary.

[0010] Optionally, the heating device may also include a control module; the control module is electrically connected to the heating component.

[0011] Optionally, the heating device is provided with a heat-insulated handle on the outside for easy carrying.

[0012] Optionally, the top of the heating cover is provided with a cover handle for gripping.

[0013] In summary, this utility model has the following beneficial effects: 1. The heating element is located within the receiving slot of the heating device and is designed to contact the bowl, allowing heat to be transferred directly from the heating device to most of the outer wall of the bowl, rather than just from the bottom, thus laying the foundation for uniform heating. Secondly, the electromagnetic interactive heating method generates heat within the bowl itself, resulting in a short heat conduction path and high efficiency, avoiding the localized hot spots found in traditional resistance heaters. Simultaneously, the flexible electromagnetic components and their corrugated surface design significantly increase the effective contact area with the bowl, ensuring that heat is evenly and densely transferred to the entire bottom of the bowl, eliminating heating dead zones. This achieves uniform and gentle heating of the food inside the bowl, effectively preventing gelatinization or nutrient loss due to localized overheating.

[0014] 2. The inner and outer shells of the bowl are separated by a vacuum cavity structure, forming a highly efficient heat insulation layer. This structure reduces the loss of heat from the inside of the bowl to the environment, so that after the target temperature is reached, the heating device only needs to work intermittently to maintain the temperature, thereby reducing overall energy consumption and achieving a highly efficient and energy-saving constant temperature effect.
