The device is implemented by aligning the axes of a steering gear 21 and a circulator 11 of a control box 1, directly sticking the lower parts of the control box 1 and a steering gear 2 on a gas stove table-board 7, directly nesting the driving gear 3 on the steering gear 21 at the top of the steering gear 2, coupling the driving gear 3 with a sleeve gear 4 through a gear, tightly sleeving the sleeve gear 4 on the outer side of a gas switch knob 5, driving the sleeve gear 4 to rotate through the driving gear 3 when the steering gear 2 rotates, thereby driving the gas switch knob 5 to rotate, realizing the adjustment of firepower and flameout operation, and when the sleeve gear 4 is pressed downwards by ignition, the driving gear 3 and the sleeve gear 4 are still in a coupling state, make driving gear 3 and set tooth 4 all be in the coupled state when the user presses and releases gas switch knob 5, guarantee user's touch signal's correct transmission and steering wheel 2 can pass through driving gear 3 drive gas switch knob 5.

After the user finishes ignition and releases the gas switch knob 5, the processor 81 recognizes the release of the user through the touch signal conversion circuit 85, at this time, counting down of default time is started, in the counting down process, whether the touch signal conversion circuit 85 has a user effective touch signal or not is periodically detected, if yes, the counting down time is reset to a default value, and counting down is restarted; the user can also adjust the countdown time through the input device 83 to prolong or shorten the time for closing the gas, and the adjustment operation of the user can be displayed through the display device 82, so that the user can confirm whether the adjustment is effective or not; before the countdown is finished, the Bluetooth transceiver 86 which is used for being connected to the device through an external Bluetooth device is successfully connected, different firepower and gas-off time in different periods can be set, and after the parameter setting is finished, the parameters are transmitted to the processor 81 through the Bluetooth transceiver 86 for execution.

After the operation that the user did not touch gas switch knob 5 or the count-down time of settlement arrived in acquiescent count-down time, this device can drive steering wheel 2 and promote the rotatory gas that closes of gas switch knob 5, and the gas is closed the back, accomplishes the primary cycle task of this device, and after the manual ignition once more of user, this device restarts a periodic task.

Because this device does not have the sensor that real-time detection gas switch knob 5 rotation angle is connected to treater 81, if in the count down time, the manual gas switch knob 5 of rotatory of user closes the gas, treater 81 does not know such user operation, so when the count down end, still can drive steering wheel 2 and rotate to the position of closing the gas, but this execution effect and the security that does not influence the system, this device is safe and reliable.

The device is characterized in that the height of a gas switch knob is not increased, and the operation of a user is facilitated by transversely expanding a control device and a power transmission mechanism.
