[0079] like Figure 6 and Figure 7As shown, the inner ring transmission part 24 is arranged on the radial inner side of the mixing chamber body 23. Since the mixing chamber body 23 is an annular structure, the radial inner area of ​​the mixing chamber body 23 forms a space for accommodating the inner ring transmission part 24.

The inner ring gas pipeline runs through both ends of each transmission pipe 2421, so that each circumferential position of the inner ring gas mixing chamber can have sufficient gas, thereby improving the uniformity of flame combustion.

[0082] In other alternative embodiments, the number of the transmission pipes 2421 in the second transmission unit 242 may be one or more, and may be specifically designed according to actual needs.

[0083] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the base 25 in this embodiment is a circular flat plate structure, which is fixed to the lower end of the mixing chamber body 23 and covers the central area of ​​the mixing chamber body 23.
