The pot frame 84 is arranged in the second cavity 72 and is framed on the periphery of the combustion part 41, the heat gathered by the heat retaining body 73 can be partially absorbed by the pot frame 84 and the combustion part 41, the heat loss rate of the combustion part 41 and the pot frame 84 can be reduced, the heat exchange between the combustion part 41 and a pot arranged on the pot frame 84 is more facilitated, the heat gathered by the heat retaining body 73 can also be exchanged with the pot, the heating efficiency and the energy utilization rate are effectively improved, and the heat loss of the burner 40 in the working process is reduced.

Specifically, the pot holder 84 includes a frame body 841 and a plurality of supporting arms 843 spaced apart from the frame body 841, the frame body 841 is located in the second cavity 72 and frames the periphery of the burning portion 41, and the plurality of supporting arms 843 extend out of the heat insulator 73 and support the pot disposed on the burner 40.

In some embodiments, the burner 40 is surrounded by the heat retaining body 73, for example, the heat retaining body 73 is cylindrical, and both ends of the heat retaining body 73 are open, so that the heat retaining body 73 is disposed on the bearing surface 21 and cooperates with the bearing surface 21 to form the first cavity 71 for accommodating the burner 40, or the retaining member 75 covers one end of the heat retaining body 73 to form the first cavity 71, i.e., the heat retaining body 73 only collects heat from the periphery of the burner 40.

In this embodiment, the heat insulator 73 is box-shaped, and the bottom and the periphery of the burner 40 are both wrapped by the heat insulator 73, that is, the heat insulator 73 gathers heat from the bottom and the periphery of the burner 40, so that the heat dissipation loss can be further reduced.

Specifically, the heat insulator 73 includes a bottom wall 731 and a side wall 732 surrounding the bottom wall 731, wherein the bottom wall 731 and the side wall 732 are heat insulating walls, the side wall 732 and the bottom wall 731 form a first cavity 71 and a second cavity 72, the bottom wall 731 supports a bottom surface of the burner 40, the side wall 732 surrounds the burner 40, and a height of the side wall 732 in a direction perpendicular to the bottom wall 731 is greater than or equal to a height of the burner 40.
