The first air outlet 1132 is arranged on the part of the first air inducing cover 140 covered on the inner fire cover 120, and the first air outlet 1132 is positioned between the first air inducing cover 140 and the inner fire cover 120, so that the first air outlet 1132 does not need to be additionally and independently arranged on the first air inducing cover 140. The air discharged through the first air outlet 1132 may flow along the outer sidewall of the inner cap 120 under the effect of the coanda effect, and because the inner fire holes 121 of the inner cap 120 are opened on the surface of the inner cap 120, the air flowing along the outer wall of the inner cap 120 may more easily flow to the positions of the inner fire holes 121 of the inner cap 120, so that the air discharged through the first air outlet 1132 may be better supplemented to the inner cap 120, and the fire of the flame generated at the inner cap 120 may be more sufficient.

In addition, it should be understood that, after the gap between the first air inducing cover 140 and the inner fire cover 120 forms the first air outlet 1132, in order to make the opening of the first air outlet 1132 larger, a gap may be formed between the circumferential bottom wall of the first air inducing cover 140 and the circumferential top wall of the inner fire cover 120, and the distance between the gaps is kept consistent, so that the first air outlet 1132 may be distributed along the circumferential direction of the first air inducing cover 140, and the size of the opening of each part of the first air outlet 1132 is consistent in the circumferential direction of the first air inducing cover 140, thereby achieving the purpose of uniformly supplying secondary air to each part of the circumferential direction of the inner fire cover 120.

In some embodiments, in order to enable the first air channel 113 of the present application to communicate with the second air mixing cavity 112, a second air outlet 1133 may be opened on a side wall of the first air inducing cover 140 facing the outer fire cover 130 under the condition that the first air inducing cover 140 encloses the inner fire cover 120 and the first air inducing cover 140 is enclosed by the outer fire cover 130, so that an opening of the second air outlet 1133 may face the outer fire cover 130, and since the outer fire cover 130 encloses the first air inducing cover 140 at intervals, secondary air in the first air channel 113 of the combustion portion 100 may flow to the outer fire cover 130 through the second air outlet 1133 on the first air inducing cover 140. Since the outer fire holes 131 are formed in the outer fire cover 130, the secondary air flowing toward the outer fire cover 130 through the first air passage 113 of the combustion part 100 may supplement air to the flame generated in the outer fire cover 130, thereby making the flame force of the flame at the outer fire cover 130 stronger.

It should be understood that the mixed gas in the second gas mixing chamber 112 of the combustion part 100 of the present application can be injected through the fire holes of the outer fire cover 130, so that the gas in the second gas mixing chamber 112 of the combustion part 100 can be more fully combusted when the secondary air in the first air channel 113 can directly supplement the secondary air to the outer fire holes 131 of the outer fire cover 130. Specifically, the outer fire hole 131 of the outer fire cover 130 may be disposed on the sidewall of the outer fire cover 130 facing the first induced air cover 140, such that the second air outlet 1133 of the first induced air cover 140 is disposed opposite to the outer fire hole 131 of the outer fire cover 130, thereby achieving the purpose of reducing the distance between the second air outlet 1133 of the first induced air cover 140 and the outer fire hole 131 of the outer fire cover 130, and further enabling the secondary air exhausted through the second air outlet 1133 of the first induced air cover 140 to reach the outer fire hole 131 of the outer fire cover 130 more rapidly. The number of the second air outlets 1133 on the first air guiding cover 140 may be multiple, and the multiple second air outlets 1133 may be arranged at intervals along the circumferential direction of the first air guiding cover 140.

In addition, it should be noted that the gas in the second gas mixing chamber 112 of the combustion part 100 is ignited after being discharged through the outer fire holes 131 of the outer fire cover 130, so in order to make the secondary air have a better combustion supporting effect on the flame at the outer fire cover 130, the secondary air can be supplemented to the root of the flame at the outer fire cover 130, and the position of the outer fire hole 131 of the outer fire cover 130 is the position of the root of the flame at the outer fire cover 130.

In this application, the height of the second air outlet 1133 of the first guiding cover 140 may be set to be not higher than the outer fire hole 131 of the outer fire cover 130, so that the secondary air exhausted through the second air outlet 1133 of the first guiding cover 140 may be supplemented to the outer fire hole 131 of the outer fire cover 130, and then the secondary air is supplemented to the flame root of the outer fire cover 130.

Specifically, the second air outlet 1133 of the first air inducing cover 140 of the present application may form a projection area on the outer fire cover 130 in a direction toward the outer fire cover 130, and the projection area located on the outer fire cover 130 is closer to the burner 110 than the outer fire hole 131 on the outer fire cover 130, so that the height of the second air outlet 1133 of the first air inducing cover 140 is lower than the outer fire hole 131 of the outer fire cover 130. When the second air outlet 1133 of the first induced air cap 140 discharges the secondary air, the initial position of the secondary air flow is lower than the outer fire hole 131 of the outer fire cap 130, and the secondary air flow can naturally rise due to the high temperature of the gas stove during operation, which correspondingly increases the temperature of the secondary air. In addition, since the air outlet of the first drafting cover 140 faces the outer fire cover 130, the secondary air discharged through the second air outlet 1133 of the first drafting cover 140 has a speed of flowing toward the outer fire cover 130 and a naturally rising speed, so that the secondary air discharged through the second air outlet 1133 of the first drafting cover 140 can flow toward the outer fire hole 131 of the outer fire cover 130, thereby supplementing the secondary air to the root of the flame generated by the outer fire cover 130.

In some embodiments, the combustion section 100 of the present application may further include a second air inducing cover 150, the second air inducing cover 150 is also disposed on the burner 110, and the second air inducing cover 150 and the burner 110 enclose to form the second air channel 114.

In addition, in order to reduce the difficulty in manufacturing the second air inducing cover 150 and save the material of the second air inducing cover 150, after the second air inducing cover 150 is disposed on the burner 110, the second air inducing cover 150, the burner 110 and the side wall of the outer fire cover 130 jointly enclose to form the second air channel 114, specifically, a cover structure is not required to be additionally disposed on the side of the second air inducing cover 150 facing the outer fire cover 130, so that the outer side wall of the outer fire cover 130 can be used as the inner wall of the second air channel 114, and the purpose of saving the material of the second air inducing cover 150 can be achieved. Of course, it should be noted that, under the above-mentioned arrangement structure of the second induced draft cover 150, the outer fire holes 131 of the outer fire cover 130 should be arranged outside the second air channel 114, so that when the outer side wall of the outer fire cover 130 is used as the inner wall of the second air channel 114, the second induced draft cover 150 does not enclose the outer fire holes 131 of the outer fire cover 130 inside, so that the mixed gas discharged from the outer fire holes 131 of the outer fire cover 130 can be smoothly combusted. Specifically, the outer fire holes 131 may be disposed at a sidewall of the outer fire cover 130 facing away from the second induced air cover 150.
