Description

Technical Field

[0002] The burner head is composed of an inner shell and an outer shell, with an air cavity between the inner shell and the outer shell. Air holes are evenly arranged on the surface of the inner shell, and high-pressure gas enters the combustion chamber in the middle of the inner shell through the air holes. Figure 1 As shown, the ignition device includes an ignition needle and an insulator, the ignition needle is surrounded by the insulator, and the insulator directly passes through the mounting holes on the outer shell and the inner shell and extends into the combustion chamber. In this installation method, a gap will inevitably appear between the insulator and the mounting hole. When high-pressure gas is introduced into the air cavity, part of the gas will be blown into the combustion chamber through the gap, making the gas in the combustion chamber unbalanced, resulting in the problem of uneven combustion of the burner head, and ultimately causing uneven heating of the wok during cooking, and even affecting the taste of the food.
