In some embodiments, as shown in fig. 2 and 5, the upper surface of the annular base 21 is formed by an outer flat surface and an inner curved surface connected to the inside of the outer surface. It can be understood that the arrangement of the outer plane can increase the contact area between the annular base 21 and the supporting portion 22, and increase the rigidity of the supporting member, so that the supporting member can stably support the utensil such as a pot. The setting of intrados can be used for guiding the flow of air, reduces the annular base 21 and to the hindrance of air, reduces the loss of air current, improves secondary air's flux to make the burning more abundant.

Optionally, as shown in fig. 2 and fig. 6, a limiting ring 211 is disposed on the lower surface of the annular base 21, and the limiting ring 211 can limit and fix the annular base 21, so as to improve the installation stability of the annular base 21.

In some embodiments, as shown in fig. 2, the inner edge of the annular base 21 is lower than the top surface of the outer ring fire cover and higher than the bottom wall of the outer ring fire cover. Therefore, after the air flows into the preset gap through the inner edge, the air tends to flow towards the outer wall surface of the outer ring fire cover, and the air reaches the outer wall surface of the outer ring fire cover in a large amount, so that the secondary air is fully supplemented. For example, if the inner edge of the annular base 21 is higher than the top surface of the outer fire cover, the airflow flows more on the top surface of the outer fire cover, and the amount of the airflow flowing to the outer wall surface is small, and if the inner edge of the annular base 21 is lower than the bottom wall of the outer fire cover, the airflow flows more on the lower portion of the bottom wall of the outer fire cover, and the amount of the airflow reaching the outer wall surface is small.

In some alternative embodiments, as shown in fig. 2, the bottom wall of the fire exit holes 111 is not lower than the lowest position of the inner edge of the ring base 21. Therefore, when the airflow flows from outside to inside, the airflow is easy to concentrate at a position lower than the bottom wall of the outgoing fire hole 111, so that the air can enter a combustion space at the root of the flame sprayed by the outgoing fire hole 111, and the supplemented secondary air can be sucked to participate in combustion, thereby effectively improving the combustion efficiency. It should be noted here that if the supplementary secondary air enters the combustion space at a distance from the base of the flame, this air is largely discharged directly without participating in the combustion.
