[0002] The existing gas stove has more and more functions, and each function needs a corresponding control switch, so more and more switches need to be installed on the valve body, such as an ignition switch.

[0003] For example, the patent application with publication number CN117308150A discloses a double micro-motion structure gas valve, which "includes a valve body and a valve cover installed at one end of the valve body, a valve rod is arranged in the valve hole of the valve cover, a spring and a rotating disc are sleeved on the middle part of the valve rod, the two ends of the spring are in contact with the rotating disc and the valve cover respectively, and the rotating disc is fixed between the middle part of the valve rod, the rotating disc is provided with a first micro-motion switch for controlling an ignition needle and a second micro-motion switch for controlling an electrical device on the circumferential side, the switch part of the first micro-motion switch and the switch part of the second micro-motion switch are both arranged towards the rotating disc, and an avoiding recess and a triggering part are formed on the rotating disc; the two micro-motion switches can be independently controlled or simultaneously controlled by using one rotating disc, so that the gas appliance can be independently controlled or simultaneously controlled by using only one gas valve to control the ignition needle and the electrical device." This is a commonly used way of arranging two micro-motion switches on the circumferential side of the rotating disc.

[0004] For example, the patent with authorization announcement number CN102966761B discloses "two micro-motion switches are arranged in a stacked manner on the valve body, the first micro-motion switch is located in the rotation track range of the first triggering block, and the second micro-motion switch is located in the rotation track range of the second triggering block." This stacked arrangement can achieve simultaneous control or separate control of the micro-motion switches.

[0005] The existing technology has the problem that different gas stoves have different functions and different requirements for switches, and manufacturers need to design gas valves according to the conditions of the gas stoves, especially the installation positions of the switches, so the gas valves cannot be widely used for various gas stoves.
