In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

As shown in fig. 1 to 4, the pot body assembly of the present embodiment includes: base 10, heating device 20 and pan body 30. The heating device 20 is disposed in the base 10. The bottom of pan body 30 is located in base 10, and pan body 30 is located above heating device 20. In this embodiment, the base 10 includes a docking platform 11 that mates with the pot in an up-and-down docking manner. The docking platform 11 has a receiving space therein for receiving the bottom of the pot 30, and the top surface of the docking platform 11 is provided with a first enclosure protrusion 12.

By applying the technical scheme of the embodiment, the heating device 20 heats the bottom of the pot body 30, and if the liquid in the pot body 30 boils and overflows to the outside of the pot body 30, the first enclosing and blocking protrusion 12 positioned on the docking platform 11 can block the liquid, so that the liquid is prevented from flowing into the docking platform 11, the liquid is prevented from damaging the heating device or electrical elements (such as a temperature controller) in the base 10, and the safety of using the cooking utensil is improved. Therefore, the technical scheme of the embodiment can solve the problem that the heating device or electrical elements in the base are easily damaged when liquid overflowing from the pot body flows into the base in the related art.

The heating device 20 may be a heating plate, a heating pipe, or a heating film, and the accommodating space is a space below the plane of the docking platform 11 and above the heating device 20.

As shown in fig. 3 and 4, when the liquid overflowing to the outside of the pot 30 is about to enter the inside of the docking platform 11, the first fencing protrusion 12 is disposed at the inner edge of the docking platform 11. The first baffle projection 12 directly provides a better barrier to liquid, effectively preventing liquid from entering the interior of the docking platform 11.

As shown in fig. 5, 6 and 8, in the present embodiment, the pot body assembly further includes a stirring structure provided at the bottom of the pot body 30, and a stirring blade of the stirring structure is used to stir the food inside the pot body 30. The docking platform 11 is provided with a detent recess 111 on its top surface. The pot body 30 is provided with a rotation stopping protrusion 33 extending into the rotation stopping concave part 111. Thus, in the process of stirring the food in the pot body 30 by the stirring blade, the rotation stopping protrusion 33 is matched with the rotation stopping concave part 111 in a rotation stopping way, so that the pot body 30 is prevented from rotating along with the stirring blade, and the stirring blade is favorable for stirring the food in the pot body 30. In order to prevent the rotation stopping recess 111 on the top surface of the docking platform 11 from interfering with the first surrounding protrusion 12, the first surrounding protrusion 12 is disposed to escape from the rotation stopping recess 111.

Note that "escape" in the setting of the first surrounding barrier projection 12 escaping from the rotation stop recess 111 means that the first surrounding barrier projection 12 is not provided at a position corresponding to the rotation stop recess 111 on the top surface of the docking platform 11. Thus, the first containment projection 12 may be of one, two, or more pieces.

Specifically, in order to provide a modified detent effect between the detent projection 33 and the detent recess 111, a pair of detent recesses 111 and a pair of detent projections 33 are provided.

In this way, a small amount of liquid that is not blocked by the first containment projection 12 will flow into the annular sump. The second containment projection 15 can block liquid that may flow to the bottom of the heat retaining cover 14, further reducing the likelihood of liquid flowing to the bottom of the heat retaining cover 14. The liquid remaining in the annular water collection tank can be directly evaporated or wiped off after use by a user. In this embodiment, the thermostat is disposed at the bottom of the heat-retaining cover 14. The second baffle protrusion 15 of the present embodiment is preferably a bent structure bent upward.
