Description

Switch structure of gas valve

Technical Field

The utility model belongs to the technical field of gas equipment, concretely relates to switch structure of gas valve.

Background

When using an ignition switch of a gas stove, people generally press and rotate a torsion bar of a pressure ignition switch to trigger an ignition device to realize ignition, but the ignition of a gas valve is often unsuccessful because a firing pin is too fast and gas does not reach, and the ignition is unsuccessful because a transition step of a switch structure cannot push a valve core open in time, so that the ignition is unsuccessful. The user is pressing and the in-process of selecting the torsion bar, and the preforming on the torsion bar can directly compress the valve core device, because the location of preforming is not enough, appears becoming flexible the aversion easily.

Therefore, further improvements are needed.
