[0040] Please refer to Figures 1-3 , the embodiment of the present application provides a cock valve electric switch device, which is applied to a gas stove, and the switch device includes:

[0041] A valve stem driving motor 1;

[0042] A reduction gearbox 2, the reduction gearbox is connected to the output shaft of the valve stem driving motor 2, and the axial center position of the reduction gearbox 2 is set as a first valve stem limiting hole 21 that can be sleeved on the valve stem 61 of the cock valve 6.

[0043] The working principle of the embodiment of the present application is as follows:

[0044] The rotation of the valve stem driving motor 1 drives the reduction gearbox 2 and the valve stem 61 of the cock valve 6 to rotate, thereby changing the angular position of the valve stem 61. Since the gas output is different at different angles of the valve stem 61, the firepower is controlled, and the cooking effect of different firepowers is achieved. That is, the embodiment of the present application does not need to pass through a knob, but directly adjusts and controls the firepower through the valve stem driving motor 1.

[0045] For example, the rotation range of the valve stem 61 is 0 - 170 degrees, or 0 - 230 degrees. Rotating to 0 degrees indicates turning off the fire, and 170 / 230 degrees indicates the minimum fire. Additionally, on the premise that the fire outlet holes are designed on the valve core of the cock valve 6, various fire control effects such as the simultaneous reduction of the "pancake" - sized fire can be achieved at specific angles. Moreover, it can cooperate with a timer to achieve automatic fire extinguishing at a set time, and cooperate with a remote controller to achieve remote control of adjusting the firepower and one - key automatic cooking and other functions.

[0046] In some possible embodiments, the speed reducer 2 includes a first mounting seat 21 that is shaped to fit the upper surface of the valve body seat 62 of the cock valve 6 and a first mounting hole 23 provided on the first mounting seat 22.

[0047] In some possible embodiments, the switch device further includes a position sensor 3 that is rotatably connected in synchronization with the valve stem 2. The position sensor 3 can monitor the real - time position and rotation angle of the valve stem 61 of the cock valve 6 in real time and feed it back to the controller, so that the controller can control the valve stem drive motor 2 in real time and flexibly.

[0049] In some possible embodiments, the axis position of the position sensor 3 is set as a second valve stem limiting hole 30 that can be sleeved on the valve stem 61 of the cock valve 6. During operation, since the valve stem 61 is directly sleeved on the second valve stem limiting hole 30 to form the central axis of the position sensor 3, thus, the central axis of the position sensor 3 rotates completely synchronously with the valve stem 61 and can accurately reflect the position and rotation angle of the valve stem 30 in real time.

[0050] In some possible embodiments, the potentiometer or encoder 3 includes:

[0051] An annular body 31, the inner side of the annular body 31 forms the second valve stem limiting hole 30, and an angle detection circuit (not shown in the figure) is provided inside the annular body 32;

[0053] An electrically controlled connection seat 33, the electrically controlled connection seat is provided on the outer side surface of the annular body, and a position signal output port 330 is provided on the electrically controlled connection seat.

[0054] Among them, the angle detection circuit can be implemented by using any existing potentiometer circuit or encoder circuit. Therefore, the present application does not limit the specific implementation manner of the angle detection circuit.

[0055] In some possible embodiments, the number of the second mounting seats 32 is set to two, and each second mounting seat 32 is provided with a second mounting hole 320 corresponding to the valve body seat 621 of the plug valve 6.

[0056] In some possible embodiments, the electric control connection seat 33 is provided with three lead-out terminals led out from the angle detection circuit through the annular body 31, and at least one lead-out terminal is set as the position signal output port 330.

[0057] In some possible embodiments, the speed reducer 2 is set as a multi-stage gear speed reducer.

[0058] In some possible embodiments, both the first valve stem limiting hole 21 and the second valve stem limiting hole 31 are D-shaped holes, which are matched with the D-shaped structure of the head of the valve stem 61 of the plug valve 6 to play a limiting role, so as to achieve the effect of synchronous rotation connection between the angle sensor or encoder and the valve stem 61.

[0059] Please refer to Figure 4 , the embodiment of the present application also provides a gas stove timing switch, including:

[0060] A timer 4, a controller 5 connected to the timer 4, and a plug valve electric switch device connected to the controller 5. Among them, the plug valve electric switch device can adopt any one or more of the plug valve electric switch devices described in the foregoing embodiments.
