[0008] As a further improvement to the above technical solution, the bottom of the outer flame cover is provided with a gas groove, and the inner and outer sides of the gas groove are provided with a plurality of first through holes arranged in a ring array.

[0009] As a further improvement to the above technical solution, the inner wall of the outer fire cover is provided with an upwardly inclined slope, and the first through hole is opened on the inclined slope.

[0024] Reference Figures 1 to 3 A burner includes: a gas distribution base 1, which includes an inlet pipe 11, a first gas passage 12 inside the inlet pipe 11, and an outer ring 15. The outer ring 15 is fixedly connected to the inlet pipe 11 by a connecting rod 13, and a second gas passage 14 inside the connecting rod 13. An outer flame cap 2 is provided on the outer ring 15, and an inner flame cap 3 is provided on the top of the first gas passage 12. The inlet pipe 11, the first gas passage 12, the connecting rod 13, and the second gas passage 14 are integrally formed. The integrally formed gas distribution base 1 simplifies the overall structure of the burner. After processing, only the outer flame cap 2 and the inner flame cap 3 need to be placed on the gas distribution base 1. The gas enters through the inlet pipe 11, part of the gas flows to the inner flame cap 3 through the first gas passage 12, and the other part of the gas flows to the outer flame cap 2 through the second gas passage 14.
