The above-mentioned heating device may preferably include a heating element and a metal heat transfer plate, the metal heat transfer plate may be welded on the bottom surface of the bottom of the pot body, and the heating element is fixed on the upper end surface of the pot body support, And it is located in the middle below the metal heat transfer plate, and the bottom of the pot body is fixed together with the bosses arranged in the pot body bracket through screws;

The above-mentioned heat transfer metal block can be selected as an aluminum plate.

The rotation structure of the pot support and the chassis can be selected as follows: a circular convex portion is provided at the center of the upper surface of the chassis, and an indentation is provided at the center of the bottom surface of the pot support and is suitable for the convex portion. The circular concave hole in the pot body bracket is rotatably placed on the convex part of the chassis, and the rotation connection between the chassis and the pot body bracket is electrically connected together .

Compared with the prior art, the utility model adopts the pot body to be arranged on the pot body support, and the pot body support is rotatably arranged on the chassis, and the heating device is located between the bottom of the pot body and the pot body support, and The heating device is electrically connected to the switch in the chassis through the rotating part of the pot body support and the chassis through the circuit, and the switch on the chassis is electrically connected to the power supply through the wire. The advantage of this structure is that the pot body is heated by the heating element through the metal heat transfer plate, and the heating element is made of PTC thermistor made of ceramic material. Because the PTC thermistor has the characteristics of automatic constant temperature, no temperature control system is required. For example, when a PTC thermistor is used to heat a liquid, even if the liquid is dried out, the PTC thermistor will not be damaged. Under normal circumstances, its service life can reach more than ten years, so it has a long service life, and the heating of the pot is stable and flexible. Evenly and effectively prevent hidden dangers such as fire, so it is very safe to use, and the pot body and the pot body support can be rotated 360° arbitrarily, so it is very convenient to move or extract food from the pot body; The temperature of the pot body can change regularly with the change of temperature through the thermistor, so the heat balance can be automatically generated at a certain temperature, as long as the switch on the chassis is turned on, the required constant temperature can be maintained, and the operation is very easy , and heated by a thermistor, due to its physical properties, it can effectively reduce its power consumption. Therefore, based on the above, the utility model not only has a reasonable design structure, is convenient to use, is safe, and consumes less power, but also has stable heat preservation and better effects. Therefore, the utility model is a very practical product and is worthy of popularization and application.
