In this way, the protrusions can reduce the distance between the detection device and the detection through hole 16 and between the ignition device and the ignition through hole 1431, which can improve the ignition success rate of the ignition device and the detection accuracy of the detection device.

Specifically, the whole gas distribution plate 100 can be made of aluminum or copper, and the aluminum has good hot-working performance and low cost. And the copper has high temperature resistance, so that the service life of the gas distribution plate 100 can be ensured.

Through setting up and passing fire groove 162 and two and pass fire hole 161 for detect through-hole 16 and form multichannel flame, promote the steady flame effect that detects through-hole 16 self further.

Specifically, referring to fig. 2, the detecting through hole 16 is formed at the first protrusion 142 of the outer sidewall 1411 of the inner cavity 141, and the fire transmitting hole 161 may be a cylindrical hole having a diameter in the range of [1.4, 3] mm, such as 1.4mm, 3mm, or other values between 1.4mm and 3 mm. Preferably, in this embodiment, the diameter may be in the range of [1.6, 2.8] mm, such as 1.6mm, 2.8mm, or other values between 1.6mm and 2.8 mm. The fire transfer groove 162 is located between the two fire transfer holes 161, may be located at the center of the two fire transfer holes 161, or may be located closer to one of the fire transfer holes 161, and is not particularly limited herein.

In addition, during ventilation, when the gas flows from the inner cavity 141 to the fire transfer groove 162 and the fire transfer hole 161, the gas in the fire transfer groove 162 is divided and decelerated through the dividing hole 15 because the fire transfer groove 162 and the fire transfer hole 161 are connected through the dividing hole 15, and the gas in the fire transfer hole 161 is divided and decelerated through the dividing hole 15, so that the gas flowing to the fire transfer hole 161 and the fire transfer groove 162 is effectively decelerated, the flame stabilizing effect is good, and the burner can have a stable working state under the small-flame work.

In the present embodiment, the ignition through hole 1431 has the same structure as the detection through hole 16.

In some embodiments, referring to fig. 1, 5 and 6, the fire transfer hole 161 includes a first section 1611 and a second section 1612, the first section 1611 and the second section 1612 are sequentially distributed in a direction away from the inner cavity 141, and the first section 1611 has a smaller pore size than the second section 1612.
