[0002] Gas stoves supply natural air to the gap between the stove body and the upper cover to supplement the lack of air during combustion, thereby promoting combustion and reducing the generation of carbon monoxide and nitrogen oxides. The air intake methods of gas stoves are divided into upper air intake, lower air intake, full air intake, etc., and they can be divided into multiple types according to different classification standards. The ignition methods of gas stoves are mainly divided into piezoelectric ceramic ignition and electric pulse ignition, and the ignition is mainly achieved by turning the knob to drive the switch shaft to rotate.

The existing gas stove switch shaft is an integral structure and needs to be replaced as a whole. The replacement is too complicated and requires professional personnel to operate. In addition, the gas stove switch shaft and the knob are only installed by plugging. After long-term use, the knob and the switch shaft will become loose, thereby affecting the rotation, operation and ignition of the gas stove switch shaft. For this reason, we propose a gas stove switch shaft. Utility Model Content
