After covering the positions of the bottom wall and / or the side wall of the pot liner 11, the heating effect is better, and when heat preservation is required after cooling, the effect can also be better achieved; on the body 1, there is a power supply socket 22 outside the accommodating cavity 12 where the heating component is arranged. This power supply socket 22 is electrically connected to the housing of an external power supply device through a power cord, so as to supply power to the heating component and provide energy for the heating component. Further, in heating, the heating means of a microwave oven can be adopted. Through the rapid rotation of water molecules in the electromagnetic field of the microwave oven, frictional heat is generated.
