It should be understood that all the first connection structures 30 in the first portion are disposed at intervals (in the embodiment of the present invention, the intervals are disposed at equal intervals), and meanwhile, the first connection structures 30 in the second portion are also disposed at intervals (in the embodiment of the present invention, the intervals are disposed at equal intervals), so that the first connection structures 30 are disposed on the burner 100 in a dispersed manner, the connection position between the first body 10 and the second body 20 is increased, the connection strength between the first body 10 and the second body 20 is further enhanced, and the problem of deformation caused by stress concentration is reduced.

Further, as shown in fig. 1, the number of the first connection structures 30 is plural, the first connection structures 30 are divided into equal numbers of first portions and second portions, the first portions are disposed corresponding to the first fire hole sides of the fire holes 40, and the second portions are disposed corresponding to the second fire hole sides of the fire holes 40, wherein the first connection structures 30 located in the first portions and the first connection structures 30 located in the second portions are disposed in one-to-one correspondence.

Specifically, in the embodiment of the present invention, the burner 100 has an approximately cylindrical structure, the first fire hole side and the second fire hole side of the fire hole 40 extend along the axial direction of the cylindrical structure, and the first fire hole side and the second fire hole side are symmetrically disposed with respect to the axial direction of the cylindrical structure, the first portions of the plurality of first connection structures 30 are disposed corresponding to the first fire hole side, and the second portions of the plurality of first connection structures 30 are disposed corresponding to the second fire hole side, and by disposing the number of first connection structures 30 in the first portion and the number of first connection structures 30 in the second portion to be identical and in one-to-one correspondence, the strength of the connection structures on opposite sides of the burner 100 can be made identical, and the strength and stability of the overall structure of the burner 100 can be further ensured.

Further, as shown in fig. 6, the plurality of fire holes 40 are arranged in two fire hole sides, namely, a first fire hole side and a second fire hole side, and the first fire hole side and the second fire hole side are each disposed along the axial direction of the burner 100 of the approximately columnar structure, and the first fire hole side and the second fire hole side are in an axisymmetric structure with respect to the columnar structure, the first portions of the plurality of first connection structures 30 are disposed corresponding to the first fire hole side, and the second portions of the plurality of first connection structures 30 are disposed corresponding to the second fire hole side.

Wherein, the fire holes 40 that first fire hole side includes are the same with the fire holes 40 that the second fire hole side includes in quantity to the one-to-one sets up, thereby makes the flame volume that the opposite both sides of combustor 100 produced the same, makes combustor 100 can evenly release heat to the outside, when combustor 100 is used for cooking utensil, has guaranteed the cooking effect of combustor 100 to food.

Further, as shown in fig. 1 and 6, the first connection structure 30 is disposed at a position on the burner 100 spaced apart from the edge of the burner 100.
