[0046] By providing a protrusion 111 on the outer side wall of the inner fire ring 11 in the fire distributor 1, a slide groove 22 is provided on the side wall of the inner fire cover 2, which cooperates with the protrusion 111 and allows the protrusion to slide therein. In this way, when installing or disassembling, it is only necessary to align the position of the protrusion 111 on the inner fire ring 11 with the position of the slide groove 22 on the inner fire cover 2 and allow the protrusion 111 to slide in the slide groove 22 on the inner fire cover 2, thereby achieving the purpose of rotational connection between the inner fire cover 2 and the inner fire ring 11 in the fire distributor 1.

[0047] Furthermore, if Figure 5 and Figure 6 As shown, the slide groove 22 is L-shaped.

[0048] By setting the slide groove 22 to be L-shaped, not only the connection between the inner fire cover 2 and the inner fire ring 11 in the fire divider 1 is made more stable, but also when disassembly and assembly are required, it is convenient for the disassembly personnel to separate the inner fire cover 2 from the inner fire ring 11 in the fire divider 1, avoiding the problem of the disassembly personnel having to rotate back and forth to separate the two, thereby achieving the purpose of convenient and simple disassembly and assembly.

[0051] By setting a fixing block 14 in the air inlet channel formed between the air isolation ring 12 and the inner fire ring 11, and passing the lower end of the ignition needle assembly 4 through the fixing part and the fixing block 14 at the same time, the stability of the ignition needle assembly 4 is improved and the shaking of the ignition needle assembly 4 is avoided.

[0052] Furthermore, if Figure 1 、 Figure 2 and Figure 8 As shown, the ignition needle assembly 4 includes an ignition needle body 41 and an elastic member 42. A positioning protrusion 411 that can be detached from the fixing block 14 is horizontally extended outward on the side wall of the ignition needle body 41. A gap is formed between the fixing block 14 and the fixing portion. The positioning protrusion 411 is located above the fixing block 14. The elastic member 42 is passed through the ignition needle body 41 and is located in the gap formed by the fixing block 14 and the fixing portion.
