The main body portion 152 is provided with an opening, and the first portion of the outlet portion includes the first outlet 142, and the opening is capable of communicating the first outlet 142 and the first area, that is, the mixed gas ejected from the first outlet 142 flows toward the first area through the opening. The second portion of the outlet portion includes a second outlet 144, i.e., the mixed gas ejected from second outlet 144 flows toward second region 134. The flow guide part 154 extends from the main body part 152 to the second area 134, the second outlet 144 is located between the flow guide part 154 and the inlet part of the ejector 140, and the flow guide part 154 has the function of guiding the gas, so that the mixed gas ejected from the second outlet 144 can be effectively guided to the second area 134, and effective and reliable structural support is provided for each position of the second area 134 where the mixed gas can be effectively filled.

The first sub-plate is provided with a metal sheet, two mounting holes are formed in the metal sheet, one mounting hole is used for fixing the thermocouple, the other mounting hole is used for fixing the ignition needle, the ignition needle discharges towards the thermocouple transversely, and mixed gas of gas and air is ignited when passing through a discharge arc.

The first expanded metal 160 is disposed on the porous ceramic plate to play a role of stabilizing flames, and when the combustion state in the porous ceramic plate is affected, the first expanded metal 160 can support the stabilization of flames, increasing the radiation effect. The first metal mesh 160 is an iron-chromium-aluminum alloy piece, and has high temperature resistance. The first wire mesh 160 may also be disposed under the porous ceramic plate to act as a flame holder.

The size of the first area in the thickness direction of the shell 110 is larger than the size of the second area 134 in the thickness direction of the shell 110, so that the mixed gas ejected from the first part of the outlet part flows from the large space to the small space, and the mixed gas ejected from the second part of the outlet part also flows from the large space to the small space, thereby being more beneficial to mixing and flowing of the mixed gas, enabling the mixed gas to be effectively filled in each position of the second area 134, enabling the mixed gas to be distributed more uniformly, further ensuring the balance and consistency of the gas amount of the mixed gas ejected from different positions of the porous carrier plate 120, enabling the flame temperature to be distributed uniformly and the combustion to be sufficient when the burner 100 works, and ensuring the cooking taste and color of food materials.

It will be appreciated that the second region 134 is located on a peripheral side of the first region, that is, the flame is emitted through the porous carrier plate 120 of the second region 134 located on the peripheral side of the first region. This be provided with and do benefit to the area of putting out a fire that increases porous carrier board 120, and then can guarantee the heating area and the heating angle of flame and edible material, can guarantee to cook the taste.
