Its core function is to provide heat for cookware by burning gas, thereby achieving the purpose of cooking, heating, etc. The traditional gas burner usually sets the gas outlet hole at the upper end or side of the burner, and the gas is directly sprayed out of the gas outlet hole and burns after mixing with air. Patent No. ZL201910442516.4 discloses a gas mixed combustor. The combustor forms an arc-shaped fire hole that rotates outward between the annular fire splitter and the annular gasket, effectively avoiding backfire and bee sound phenomenon, ensuring stable combustion of gas, thereby solving the problems of unstable gas combustion and low thermal efficiency. However, this design still has some shortcomings in actual use: first, because the top plate of the secondary air chamber is close to the fire cover assembly, the sprayed flame will directly hit the top plate of the secondary air chamber, which can easily burn out the top plate after long-term use, affecting the service life of the burner; second, there is a gap between the fire-retardant ring and the top plate of the secondary air chamber, which can easily cause the phenomenon of fire leakage, not only reducing the combustion efficiency, but also possibly causing safety hazards; third, the mixing effect of the mixing pipe is not ideal, resulting in uneven mixing of gas and air, uneven combustion, further affecting the thermal efficiency and stability of the burner.

[0003] In summary, although the existing gas burner has been improved in structure, it still has problems such as uneven combustion, low thermal efficiency, easy burning and fire leakage. Therefore, a new type of gas burner design is needed to solve the above problems, improve the thermal efficiency and stability of the burner, and improve the user experience. UTILITY MODEL CONTENTS
