The support frame 21 is used to carry the heating plate 23 and the heating tube 22 to facilitate the installation of the heating plate 23 and the heating tube 22. The heating tube 22 is connected to the internal circuit of the base body 1. When the heating base is powered on, the heating plate 23 can be heated based on the heating tube 22.

[0030] Specifically, one end of the temperature sensor 3 is set as a detection end, and the other end extends a signal connection line based on the temperature sensor 3.

[0031] Furthermore, a display screen assembly can be provided on the outer wall of the base body 1, and the display screen assembly is electrically connected to a main control component inside the base body 1.

[0032] Furthermore, the through hole on the support frame 21 is correspondingly arranged below the temperature sensor 3 so that the signal connection line of the temperature sensor 3 extends to the inside of the base body 1 and the simplicity of the line routing in the heating base can be improved.

[0033] Specifically, the support frame 21 is provided with a first step surface 211 for supporting the heating plate 23 and a second step surface 212 for supporting the cookware. The support frame 21 is embedded in the base body 1, and the first step surface 211 and the second step surface 212 are provided at the position where the support frame 21 cooperates with the base body 1. The second step surface 212 is arranged on the periphery of the first step surface 211. The heating plate 23 is matched on the first step surface 211, so that the cookware can be located above the heating plate 23 when it is matched on the second step surface 212, so that the heating plate 23 can heat the cookware.

[0034] Furthermore, the first stepped surface 211 is provided with a slot, and the heating plate 23 is snap-fitted into the slot of the first stepped surface 211, and the slot structure improves the tightness of the heating plate 23 and the base body. The heating plate 23 can also be fixed to the first stepped surface 211 by adhesive bonding, and the adhesive is a heat-insulating adhesive, which improves the thermal conductivity between the heating plate 23 and the support frame 21 and reduces the heat loss of the heating plate 23.

[0038] Specifically, any of the grooves maintains a preset distance from the heating tube 22, that is, the temperature sensor 3 in the groove can be distributed at different positions around the heating tube 22, so as to improve the temperature detection of different positions of the heating plate 23 by the temperature sensor 3, and improve the reliability of the temperature detection of the heating plate 23 by the temperature sensor 3.

The main control component 11 sets the heating time of the food in the cookware and the heating power of the heating plate 23 according to the temperature of the heating plate 23 obtained by the temperature sensor 3 and the heat conversion efficiency between the heating plate 23 and the cookware. The main control component 11 generates an adjustment instruction based on the working temperature of the heating plate 23 fed back by the temperature sensor 3, and controls the heating efficiency and working time of the heating component 2 based on the adjustment instruction, so as to ensure that the working temperature of the heating plate 23 in the heating component 2 is maintained within a preset range, thereby extending the working life of the heating component 2.

[0046] The embodiment of the utility model provides a heating base. By arranging a temperature sensor 3 in the heating plate 23 of the heating base, the working temperature of the heating plate 23 is obtained based on the temperature sensor 3. The working state of the heating base can be adjusted in real time according to the working temperature of the heating plate 23, thereby improving the working reliability of the heating base and ensuring the cooking taste of the food.
