The present invention provides a gas safety ignition switch, comprising components of a gas switch body, a closer unit, a rotary knob unit, a presser, a micro switch and an electronic ignition device, characterized in that: one side of the gas switch body is configured with an opening, the opening being corresponding to an actuation point of the micro switch and the spindle, an actuator, configured inside the opening in a movable manner, including an contacting end and a pushing end, the pushing end being corresponding to the actuation point of the micro switch; the edge of the driving diaphragm is also configured with an indentation corresponding to one end of the actuator; thus, when pressing the spindle of the rotary knob unit, the driving diaphragm can move so that the contacting end of the actuator will be right inside the indentation, and when turning the spindle, the driving diaphragm will turn synchronously to tightly push against the contacting end, and will push the actuator to further drive the micro switch, so that the electronic ignition device can ignite the gas. |

1. A gas safety ignition switch, comprising components of a gas switch body, a closer unit, provided inside the gas switch body, a rotary knob unit, provided on one end of the gas switch body and connected with the closer unit, including a spindle that can be turned to drive the closer unit, a driving diaphragm, provided on the spindle of the rotary knob unit, a micro switch, provided on one side of the gas switch body, and an electronic ignition device electrically connected with the micro switch; its characteristics lie in that:
one side of the gas switch body is configured with an opening, the opening being corresponding to an actuation point of the micro switch and the spindle; an actuator, configured inside the opening in a movable manner, including an contacting end and a pushing end, the contacting end being corresponding to the spindle, and the pushing end being corresponding to the actuation point of the micro switch; the edge of the driving diaphragm is also configured with an indentation corresponding to one end of the actuator; thus, when pressing the spindle of the rotary knob unit, the driving diaphragm can move downward so that the contacting end of the actuator will be right inside the indentation, and will not push the actuator; and when turning the spindle, the driving diaphragm will turn synchronously to tightly push against the contacting end, and will push the actuator to further drive the micro switch, so that the electronic ignition device can ignite the gas; when ignition is completed and the spindle is no longer pressed, the driving diaphragm will move upward, the shifting bar will be reset through elasticity, and the contacting end can protrude to the bottom side of the driving diaphragm, to block the driving diaphragm moving downward, so as to avoid repetitive ignitions caused by mistake pressing on the spindle. |
