Description

Technical Field

[0001] The invention relates to the technical field of burners, and in particular to a gas mixing burner with complete combustion. Background Art

[0002] As a kind of daily necessities, gas burners are gradually integrated into people's lives. The air outlet of traditional gas burners is generally set at the upper end of the burner or on the side of the burner. Since the gas is directly ejected from the air outlet, flashback and buzzing are inevitable. The gas burns unevenly, which easily leads to uneven heat distribution of the burner. Moreover, the flame is unstable during combustion and is easily affected by the external environment, thereby affecting the heating effect of the burner on the pot, resulting in low thermal efficiency of the burner, affecting the user's experience. The invention patent with the authorization announcement number CN201910442516.4 discloses a gas mixing burner, which forms an arc-shaped fire hole rotating outward between the annular fire-dividing plate and the annular gasket to avoid flashback and buzzing of the burner, ensure the stable combustion of the gas, and solve the problems of unstable gas combustion and low thermal efficiency. However, with only an arc-shaped fire hole, it is difficult to control the concentration and dispersion of the flame, resulting in insufficient and uneven combustion and poor use effect. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to improve the prior art. Summary of the invention
