The sealing member is tightly fitted between heat conduction assembly 30 and pan body 20 to seal the gap between heat conduction assembly 30 and pan body 20. The direction of the heat conduction assembly 30 and the pot body 20 pressing the sealing member is defined as the pressure direction, and the dimension of the sealing member between the heat conduction assembly 30 and the pot body 20 along the pressure direction in the non-pressed state is H1, and H1 is more than or equal to 0.5 mm.

The gap between the heat conducting assembly 30 and the pot body 20 is sealed by a sealing element, the sealing effect is related to the dimension H1 of the sealing element in the pressure direction, and when the dimension H1 reaches a certain value, namely H1 is more than or equal to 0.5mm, the sealing element can form good sealing effect, so that liquid can be prevented from leaking at the through hole 201.

Referring to fig. 1, the cooking device of the present invention further includes a base 10, wherein the base 10 has a cavity 101, and the cavity 101 is used for accommodating the pot body 20. A temperature sensor 40 is arranged in the base 10, and specifically, the temperature sensor 40 is located at the bottom of the cavity 101. When the pot body 20 is put into the receiving cavity 101, the temperature sensor 40 contacts the second heat transfer member 32, so that the temperature sensor 40 can detect the temperature of the second heat transfer member 32. Since the second heat-conducting member 32 is connected to the first heat-conducting member 31, and the first heat-conducting member 31 faces the inside of the pot body 20, the heat of the food material can be timely conducted to the second heat-conducting member 32 through the first heat-conducting member 31, and thus the temperature of the food material can be accurately detected by detecting the temperature of the second heat-conducting member 32.

Specifically, the second lever portion 322 is connected to the first lever portion 312. The sealing member comprises a second sealing member 60 tightly fitted between the second head 321 and the outer wall of the pot body 20. Thus, a good seal can be formed between the second head 321 and the outer wall of the pot body 20, which can effectively prevent the liquid in the pot body 20 from leaking from the through hole 201 on one hand, and can prevent the external liquid from entering the through hole 201 when the pot body 20 is cleaned on the other hand. It can be understood that, since the second sealing member 60 is tightly fitted between the second head 321 and the outer wall of the pot body 20, the pressure direction refers to the thickness direction of the second sealing member 60, i.e. the up-down direction in fig. 3, and therefore, H1 refers to the thickness of the second sealing member 60 when not pressurized.

Referring to fig. 3, in one embodiment, the second sealing element 60 is disposed near the outer periphery of the second head portion 321. In this way, the formation of a gap on the outer peripheral side of the second seal 60 can be avoided, and a better sealing effect can be obtained.
