In the utility model, the splitter vane 30 is arranged at the position of the gas inlet 22, the splitter orifice 31 is arranged, and the splitter vane 30 and the gas inlet 22 are provided with a spacing space. When the fuel gas is ejected and diffused from the ejector pipe 10 to the fuel gas diffusion pipe 20, the fuel gas cannot be directly ejected to the combustion holes 21 near the fuel gas inlet 22 due to the blocking of the splitter plate 30, but most of the air flow of the fuel gas diffuses to two sides in the interval space, and the local fuel gas flows to the other side of the splitter plate 30 from the splitter hole 31, so that the fuel gas is supplied to the combustion holes 21 near the fuel gas inlet 22; the arrangement structure ensures that the gas flow of the gas in the gas diffusion pipe 20 can be mostly diffused towards the two sides of the gas diffusion pipe 20, but not accumulated on the combustion holes 21 at the position of the gas inlet 22, so that the gas is uniformly supplied at the positions of the burner close to the injection pipe 10 and far from the injection pipe 10, and the gas combustion in each area of the burner is more uniform; moreover, under the blocking of the splitter plates 30, the gas flow can collide to form disturbance, so that the fuel and the air are mixed more fully, the mixing degree of the gas is improved, the gas combustion is ensured to be full, and the carbon monoxide emission reaches the standard.

The arrangement of the splitter plates 30 ensures that the utility model does not need to form a venturi tube structure by a stamping process at the position of the injection pipe 10, can ensure higher combustion efficiency of fuel gas and ensure that the emission of carbon monoxide reaches the standard. Therefore, the structure of the burner can be simplified, the injection pipe 10 is provided with a complete through pipe structure, a plurality of procedures and dies are not required to be arranged, the process can be effectively simplified, the production cost is reduced, and the defective rate is reduced.
