[0029] To make the objectives, technical solutions and advantages of this application clearer, the following will describe the technical solutions of this application in detail through implementation manners with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. Without conflict, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0030] It should be noted that: in the accompanying drawings, the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions; in the description of this application, the terms "center", "longitudinal", "lateral", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation on the scope of protection of this application; in the description of this application, "first", "second", etc. are only used for distinction from each other, rather than indicating their importance and sequence, etc.

[0031] In the description of this application, unless otherwise clearly specified and limited, the terms "mounted", "connected", "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a movable connection, or a detachable connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements, etc. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0032] Referring to Figures 1 - 3 , an embodiment of this application provides a plug valve fire control device applied to a gas stove, and the fire control device includes:

[0033] A controller 1, the controller 1 having a control signal input port and a control signal output end electrically connectable to a flow regulating valve 31 of a plug valve 33;

[0034] An angle sensor 2, the axis position of the angle sensor 2 being set to a valve stem limiting hole 20 sleevable on a valve stem 30 of a plug valve 3, and the angle sensor 2 further having a position signal output port 21 electrically connected to the controller 1.

[0035] In the embodiment of the present application, by providing the valve stem limiting hole 20 at the axis position of the angle sensor 2, the angle sensor can be sleeved on the valve stem 30, and the valve stem 30 is used as the central axis of the angle sensor 2 to rotate synchronously therewith, so as to accurately and real-time obtain the position angle of the valve stem 30, and feed back the real-time angle position of the valve stem 30 to the controller 1, and the controller 1 sends a control signal to the flow regulating valve 31 according to the real-time angle position, for example:

[0036] Exemplarily, when the valve stem 30 rotates from 0 degrees to 230 degrees, an opening signal is sent to the flow regulating valve 31 at the 90-degree position, and at the same time, the inner-ring firepower and the outer-ring firepower of the gas stove are increased; a closing signal is sent to the flow regulating valve 31 at the 180-degree position, then the inner-ring firepower becomes smaller and the outer-ring firepower is closed; and a signal is sent to the flow regulating valve 31 at the 230-degree position, then the inner-ring firepower becomes smaller and the outer-ring firepower becomes larger, etc.

[0037] The whole process achieves the technical effects of flexible adjustment, precise control of the firepower of the gas stove, and significant improvement in the degree of intelligence. It is particularly suitable for relatively complex cooking scenarios such as automatic cooking, soup making, and stir-frying.

[0038] In some possible implementation manners, the angle sensor 2 is set as a potentiometer or an encoder.

[0039] In some possible implementation manners, the potentiometer or encoder 2 includes:

[0040] A ring-shaped main body 22, the inner side of the ring-shaped main body 23 forms the valve stem limiting hole 20, and an angle detection circuit is arranged inside the ring-shaped main body 22;

[0041] At least two mounting seats 23, the at least two mounting seats 23 being evenly distributed on the outer side surface of the ring-shaped main body 22;

[0042] A connecting seat 24, the connecting seat 24 being arranged on the outer side surface of the ring-shaped main body 22, and the position signal output port 21 being arranged on the connecting seat 24.

[0043] Among them, the angle detection circuit can be implemented by using any existing potentiometer circuit or encoder circuit. Therefore, this application does not limit the specific implementation manner of the angle detection circuit.

[0044] In some possible implementation manners, the valve stem limiting hole 20 is set as a D-shaped hole to cooperate with the D-shaped structure at the head of the valve stem 30 of the plug valve 3 to play a limiting role, achieving the effect of synchronously rotating and connecting the angle sensor or encoder with the valve stem 30.

[0045] In some possible implementation manners, at least one mounting hole 240 is provided on each mounting seat 24.

[0046] In some possible implementation manners, in order to be as consistent as possible with the structure of the valve body seat 32 of the plug valve 3 and make the mounting structure as simple and compact as possible, the number of the mounting seats 23 is set to two, and each mounting seat 23 is provided with a mounting hole 230 corresponding to the valve body mounting hole 321 on the valve body seat 32 of the plug valve 3.

[0047] In some possible implementation manners, three lead-out ends are provided on the connection seat and lead outwards from the angle detection circuit through the annular main body, and at least one lead-out end is set as the position signal output port 21, and the other two lead-out ends can be used as control signal transmission ports connected to the controller 2.

[0048] In some possible implementation manners, the fire control device further includes the flow regulating valve 31.

[0049] In some possible implementation manners, the flow regulating valve 31 is a self-priming valve, a pressure stabilizing valve or a blower.

[0050] In some possible implementation manners, the controller 1 is set as a timing controller, so that the effect of triggering the controller 1 to automatically close the plug valve 3 can be achieved through simple timing processing, which is very convenient and practical. Of course, the controller 1 can also be combined with other control functions, such as being combined with an ignition controller to implement, or being independently implemented as a controller, etc.

[0051] Please refer to Figure 3 , this application embodiment also provides a plug valve 3, which is applied to a gas stove. The plug valve 3 includes a valve stem 30 and a flow regulating valve 31, and also includes the plug valve fire control device or the gas stove timing switch described in any one or more of the foregoing embodiments. Among them, the angle sensor 2 is sleeved on the valve stem 30 through the valve stem limiting hole 20. Correspondingly, the technical effects of any one or more of the foregoing embodiments can also be fully extended to the plug valve of this embodiment, and will not be elaborated one by one.
