[0032] Embodiment 3: The rest of the embodiment is the same as that of embodiment 2, except that two partition bars 18 are provided, and the two partition bars 18 are distributed in the transverse direction.

[0033] By setting the dividing strips 18, the combustion-supporting mixed gas flowing through is divided and flows obliquely upward to both sides, so as to reduce the amount of gas just above the outlet end of the secondary air hole 15, which helps to further improve the uniformity of the distribution of the combustion-supporting mixed gas. The number and position of the dividing strips 18 depend on the actual situation.

[0034] Embodiment 4: Figure 1 and Figure 2 As shown, the rest of the parts are the same as those in the first embodiment, except that two auxiliary air holes 15 are provided, and the axes of the two auxiliary air holes 15 are located on the same straight line.

At the position where the cut surface 19 is located, the valve 1 is connected to the insulation cup 2 (see Figure 4 ) is wider, more combustion-supporting mixed gas can flow upward from there into the insulating cup 2, which helps to further improve the uniformity of the distribution of the combustion-supporting mixed gas.

[0036] Embodiment 5: Figure 4 and Figure 5 As shown, an air outlet mechanism includes an insulation cup 2, an air mixing pipe 3, an iron cup 4 and any one of the air outlet parts of the first to fourth embodiments, the bottom of the insulation cup 2 is provided with a mounting hole 21, the lower section 11 of the valve 1 is provided with the mounting hole 21, the middle section 12 and the upper section 13 of the valve 1 are both located in the insulation cup 2, the middle part of the air mixing pipe 3 is provided with an air inlet 31, the lower part of the air mixing pipe 3 is provided with a boosting cavity 32, the boosting cavity 32 is provided with a boosting sheet 33, a sealing ring 34, a filter 35 and a rubber tail cap 36 from top to bottom, and the iron cup 4 is sleeved on the insulation cup 2. Among them, the insulation cup 2 is a ceramic cup, and the area above the valve 1 in the insulation cup 2 is a combustion chamber, and after the mixed gas is ignited, flames will be formed in the combustion chamber and the area above the insulation cup 2.

[0037] In this embodiment, the inner wall of the heat-insulating cup 2 is provided with a first inner ring 22, a second inner ring 23, and a third inner ring 24, which are distributed from bottom to top. The inner diameters of the first inner ring 22, the second inner ring 23, and the third inner ring 24 increase in sequence.

The drainage groove 16 is connected to the air storage chamber 5. The air storage chamber 5 helps to distribute the combustion-supporting mixed gas more evenly. Preferably, the positioning ring 111 is integrally formed with the lower section 11 of the valve 1.

[0038] Example 6: Figure 4 and Figure 5 As shown, the rest of the parts are the same as those of the fifth embodiment, the difference being that the height of the lower end surface of the stopper 17 is lower than the height of the upper end surface of the second inner ring 23, ensuring that most of the combustion-supporting mixed gas that flows out of the auxiliary air hole 15 and directly flows upward hits the stopper 17.

[0039] It should be noted that the insulation cup 2 is generally a ceramic cup, which may break if it comes into contact with the block 17 or the separator 18. In this solution, a small distance needs to be maintained between the block 17, the separator 18 and the second inner ring 23 to prevent the insulation cup 2 from breaking.
