In a specific example, the second gas separation channel 120 is used to convey the mixed gas to the second gas mixing chamber 2231, and the second gas mixing chamber 2231 conveys the gas to the second gas outlet 221, so as to convey the gas toward the second gas outlet 221 by using the second gas separation channel 120.

Here, when the cover plate 224 is connected to the top opening of the fire stabilizing cavity 2232, the cover plate 224 and the fire cover seat 223 cooperate to define the fire stabilizing groove 226 which communicates the fire stabilizing cavity 2232 with the external space of the second fire cover 220, and at this time, the gas in the fire stabilizing cavity 2232 can be ignited by the fire stabilizing groove 226, so that a flame is formed in the fire stabilizing cavity 2232, and at the same time, the flame in the fire stabilizing cavity 2232 can be ensured to ignite the gas in the external space of the second fire cover 220, so as to achieve the purpose of flame stabilizing.

It should be noted that, because the fire stabilizing groove 226 is located above the second air outlet 221, the flame in the fire stabilizing cavity 2232 can ignite the air led out from the second air outlet 221 through the fire stabilizing groove 226, so as to realize stable combustion of the air, thereby improving the heating stability of the second fire cover 220 and ensuring the heating quality of the burner 1000.

In some examples, a portion of the fire cover seat 223 above the second air outlet 221 is recessed away from the cover plate 224, so as to form a fire stabilizing groove 226 between the cover plate 224 and the fire cover seat 223, thereby facilitating communication between the fire stabilizing cavity 2232 and the space outside the second fire cover 220, ensuring that the flame can be effectively formed in the fire stabilizing cavity 2232, and simultaneously enabling the flame in the fire stabilizing cavity 2232 to ignite the gas guided out by the second air outlet 221, thereby improving the combustion stability of the gas guided out by the second air outlet 221 and achieving the purpose of flame stabilizing.
