[0043] Figure 1 A schematic structural diagram of a gas stove switch device provided in this embodiment is shown. Figure 2 The exploded schematic diagram of the gas stove switch device provided in this embodiment is shown. Figure 3 FIG. 2 shows a cross-sectional schematic diagram of the gas stove switch device provided in this embodiment. Figure 1-Figure 3 As shown, this embodiment provides a gas stove switch device, which includes a control valve 1, a firing knob 2 and a timing module 3. The control valve 1 includes a valve body 11 and a valve stem 12 rotatably arranged on the valve body 11; the firing knob 2 is connected to the top of the valve stem 12 and can drive the valve stem 12 to rotate; the timing module 3 includes a timing dial assembly 31 and a timing paddle switch 32, the timing dial assembly 31 is sleeved on the valve stem 12 and is located between the valve body 11 and the firing knob 2, and the timing paddle switch 32 is located on one side of the valve stem 12; the timing paddle switch 32 includes a first fixed end 321 arranged on the valve body 11 and a timing paddle 322 movably arranged on the first fixed end 321, and rotating the timing dial assembly 31 can drive the timing paddle 322 to move to transmit a timing signal.

[0044] The gas stove switch device provided in this embodiment can drive the valve stem 12 to rotate by turning the fire knob 2 to realize the ignition operation of the stove; rotating the timing dial assembly 31 can drive the timing paddle 322 to move, which can transmit the timing signal, effectively avoiding accidents such as overburning and gas leakage caused by the user forgetting to turn off the fire, and ensuring the safety of the gas stove; when the user uses the gas stove switch device, the timing control of the stove can be realized through a simple twisting action, which is convenient and quick to operate, and can also omit unnecessary wiring harnesses for easy assembly.

[0045] In this embodiment, the timing paddle 322 is swingably disposed on the first fixed end 321, and the action of the timing paddle 322 is to specify that the paddle 322 swings relative to the first fixed end 321, and the timing paddle 322 can automatically reset after swinging a first preset angle relative to the first fixed end 321. At this time, the timing paddle 322 swings the first preset angle relative to the first fixed end 321 and resets, which is defined as one action. The controller of the gas stove records the unit time length of the timing paddle 322 action once as t. Of course, in other embodiments, the timing paddle 322 can also be slidably disposed on the first fixed end 321, and the action of the timing paddle 322 is to specify that the paddle 322 slides relative to the first fixed end 321. At this time, the timing paddle 322 slides the first preset distance relative to the first fixed end 321 and resets, which is defined as one action. The controller of the gas stove records the unit time length of the timing paddle 322 action once as t. For the convenience of description, this embodiment is described by taking the timing paddle 322 swingably disposed on the first fixed end 321 as an example.

[0046] Figure 4 A schematic structural diagram of the control valve 1 provided in this embodiment is shown. Figure 5 FIG. 2 shows a schematic diagram of the structure of the firing knob 2 provided in this embodiment. Figure 4-Figure 5 As shown, the valve stem 12 is engaged with the firing knob 2 to ensure that the firing knob 2 can drive the valve stem 12 to rotate, thereby realizing the ignition operation of the stove. Optionally, a plug hole 21 is provided on the firing knob 2, and the valve stem 12 can be plugged into the plug hole 21 to realize the engagement between the firing knob 2 and the valve stem 12. It should be noted that the shape of the plug hole 21 is not circular, and the cross-sectional shape of the top of the valve stem 12 is the same as the shape of the plug hole 21, so as to prevent the firing knob 2 and the valve stem 12 from rotating relative to each other, thereby affecting the firing efficiency.

[0047] Exemplarily, the shape of the plug hole 21 can be a regular polygon, an irregular polygon, or an irregular shape composed of connected straight lines and curves. In this embodiment, the cross-sectional shape of the top of the valve stem 12 is D-shaped, and a limiting plate is also provided on the top of the valve stem 12. The plug hole 21 is D-shaped, and a limiting hole connected to the plug hole 21 is also provided on the firing knob 2. The valve stem 12 can be plugged into the plug hole 21, and the limiting plate can be plugged into the limiting hole of the firing knob 2, thereby further ensuring the fixing effect between the firing knob 2 and the valve stem 12.

[0048] Figure 6 A schematic structural diagram of the manual dial 311 provided in this embodiment is shown. Figure 7 FIG. 3 shows a schematic diagram of the structure of the transmission dial 312 provided in this embodiment. Figure 6-Figure 7 Combined with Figure 2 As shown, the timing dial assembly 31 includes a manual dial 311 and a transmission dial 312 arranged and connected in the upper and lower parts, and the transmission dial 312 is provided with a plurality of timing toggle teeth spaced along its circumferential direction; when the timing paddle 322 is located at the middle position of the first fixed end 321, it can extend between two adjacent timing toggle teeth, and when the timing paddle 322 swings a first preset angle, it can be disengaged from between two adjacent timing toggle teeth and reset. By setting the connected manual dial 311 and the transmission dial 312, the manual dial 311 can be set above the stove panel 100 to facilitate the user to rotate, and the transmission dial 312 and the timing paddle switch 32 are set below the stove panel 100 to prevent the user from accidentally touching and ensure the user's safety. In addition, in this embodiment, when the user rotates the timing dial assembly 31, the timing paddle 322 swings a first preset angle and can be disengaged from between two adjacent timing toggle teeth of the transmission dial 312 and reset, at which time, the controller of the gas stove records the unit time length as t. With this setting, each time the user turns on the stove for use, the timing paddle 322 is in the middle position of the first fixed end 321, that is, there is no timing duration in the initial state of the gas stove. This can avoid the situation where the user forgets to reset the timing module 3 after using the gas stove, resulting in an initial timing duration when the gas stove is restarted, and the initial timing duration cannot meet the current cooking needs, resulting in the flameout in the middle of cooking.

[0049] Preferably, the timing paddle switch 32 is a two-way paddle switch. When the user turns the manual dial 311 clockwise, the timing duration increases, and when the user turns the manual dial 311 counterclockwise, the timing duration decreases, so as to meet the cooking time requirement, improve the taste of cooked food, and enhance the user experience. It should be noted that the two-way paddle switch is a prior art, and the specific structure of the two-way paddle switch is not described in detail in this embodiment.

[0050] It should be noted that the middle position of the first fixed end 321 refers to the timing paddle 322 being located at the "0 gear" of the first fixed end 321. When the timing paddle 322 swings clockwise at a first preset angle, the timing paddle 322 is located at the "1 gear" of the first fixed end 321. When the timing paddle 322 swings counterclockwise at a first preset angle, the timing paddle 322 is located at the "-1 gear" of the first fixed end 321. In this embodiment, when the timing paddle 322 is set to be located at the "1 gear" of the first fixed end 321, the controller adjusts the timing duration to increase; when the timing paddle 322 is set to be located at the "-1 gear" of the first fixed end 321, the controller adjusts the timing duration to decrease. Of course, in other embodiments, the corresponding relationship between the increase or decrease of the timing duration and the position of the timing paddle 322 can also be adjusted according to the installation position of the timing paddle switch 32, and this embodiment is not limited to this. In addition, the first preset angle is the angle at which the timing paddle 322 swings from the "0 gear" of the first fixed end 321 to the "1 gear" or from the "0 gear" of the first fixed end 321 to the "-1 gear". This embodiment does not limit the specific value of the first preset angle, and designers can make adjustments based on the model of the timing paddle switch 32 they choose.

[0051] It should be noted that the manual dial 311 and the transmission dial 312 are both sleeved on the valve stem 12, but the timing paddle 322 can extend between two adjacent timing dial teeth of the transmission dial 312, and the force exerted by the timing paddle 322 on the transmission dial 312 is greater than the friction between the transmission dial 312 and the valve stem 12. Therefore, the manual dial 311 and the transmission dial 312 can both rotate relative to the valve stem 12, but cannot rotate with the valve stem 12.

[0052] like Figure 6-Figure 7 As shown, one of the manual dial 311 and the transmission dial 312 is provided with a connection slot, and the other is provided with a connection convex, which is engaged with the connection slot to achieve the connection between the manual dial 311 and the transmission dial 312, so that when the user turns the manual dial 311, the transmission dial 312 can be driven to rotate synchronously. Specifically, the manual dial 311 includes a first dial 3111 and a first connecting portion 3112 connected to each other, and the transmission dial 312 includes a second dial 3121 and a second connecting portion 3122 connected to each other, the first dial 3111 is located above the first connecting portion 3112, the second dial 3121 is located below the second connecting portion 3122, and the first connecting portion 3112 and the second connecting portion 3122 are engaged with each other. In this embodiment, the first connection part 3112 and the second connection part 3122 are both cylindrical structures, and the first connection part 3112 is sleeved outside the second connection part 3122 to increase the contact area between the first connection part 3112 and the second connection part 3122 and improve the stability of the connection between the two.

[0053] In this embodiment, a connection protrusion is provided on the inner wall of the first connection part 3112, and a connection slot is provided on the outer wall of the second connection part 3122. Optionally, there are multiple connection protrusions, and the multiple connection protrusions are arranged at intervals along the circumference of the first connection part 3112, and each connection protrusion can correspond to a connection slot. Of course, in other embodiments, the connection protrusion can also be arranged on the outer wall of the second connection part 3122, and the connection slot can be arranged on the inner wall of the first connection part 3112, which can also achieve the above effect.

[0054] like Figure 6-Figure 7 Combined with Figure 3 As shown, an elastic member 313 is provided between the manual dial 311 and the transmission dial 312. By providing the elastic member 313, on the one hand, when the user turns the firing knob 2 to perform the ignition operation, the firing knob 2 needs to be pressed downward at the same time. The provision of the elastic member 313 can provide a certain travel space for the manual dial 311 to ensure the normal pressing and ignition operation of the firing knob 2; on the other hand, the elastic member 313 can also limit the transmission dial 312 to prevent the transmission dial 312 from moving along the axis direction of the valve stem 12, causing the timing paddle 322 to disengage from the two adjacent timing toggle teeth of the transmission dial 312, thereby affecting the timing operation. In this embodiment, the elastic member 313 is a spring, which has a simple structure, is easy to assemble, and is easy to obtain materials, which can reduce production costs.

[0055] In order to ensure the smooth movement of the manual dial 311 along the axial direction of the valve stem 12, in the present embodiment, the connecting protrusion and the connecting groove are both long strips and extend along the axial direction of the valve stem 12, so as to achieve the effect that the manual dial 311 and the transmission dial 312 can move relative to each other along the axial direction of the valve stem 12, and the manual dial 311 can drive the transmission dial 312 to rotate synchronously when it rotates.

[0056] To facilitate the user to rotate the manual dial 311 , the outer surface of the manual dial 311 is provided with a plurality of anti-slip edges at intervals along its circumference to prevent the user's fingers from sliding relative to the manual dial 311 and affecting the timing operation.

[0057] In the prior art, the control valve 1 is usually not set with a fixed gear. The firepower is freely adjusted by the user by turning the firing knob 2 to drive the valve stem 12 to rotate. When using, the user needs to observe the size of the flame to determine whether it is in the corresponding gear, and cannot know for sure whether the firing knob 2 is screwed in place. If the position of the firing knob 2 is adjusted improperly, flameout noise, backfire and other phenomena may occur, and harmful gases such as CO may also be generated, affecting the health of the user. Figure 1-Figure 3In order to solve this problem, the gas stove switch device also includes a firepower adjustment module 4, which includes a firepower adjustment dial 41 and a firepower paddle switch 42. The firepower adjustment dial 41 is sleeved on the valve stem 12, and the firepower paddle switch 42 is located on one side of the valve stem 12. The firepower paddle switch 42 includes a second fixed end 421 arranged on the valve body 11 and a firepower adjustment paddle 422 movably arranged on the second fixed end 421. Turning the ignition knob 2 can drive the firepower adjustment paddle 422 to move through the valve stem 12 to transmit a firepower gear position signal.

[0058] In this embodiment, the fire power adjustment paddle 422 is swingably arranged on the second fixed end 421, and the action of the fire power adjustment paddle 422 refers to the swing of the fire power adjustment paddle 422 relative to the second fixed end 421, and the fire power adjustment paddle 422 can automatically reset after swinging the second preset angle relative to the second fixed end 421. At this time, the swing of the fire power adjustment paddle 422 relative to the second fixed end 421 by the second preset angle and reset is defined as one action, and the action of the fire power adjustment paddle 422 once controls the gas stove controller to adjust the fire power of the gas stove by one gear. Of course, in other embodiments, the fire power adjustment paddle 422 can also be slidably arranged on the second fixed end 421, and the action of the fire power adjustment paddle 422 refers to the sliding of the fire power adjustment paddle 422 relative to the second fixed end 421. At this time, the sliding of the fire power adjustment paddle 422 relative to the second fixed end 421 by the second preset distance and reset is defined as one action, and the action of the fire power adjustment paddle 422 once controls the gas stove controller to adjust the fire power of the gas stove by one gear. For the convenience of description, this embodiment is described by taking the example that the fire power adjustment paddle 422 is swingably disposed on the second fixed end 421 .

[0059] Figure 8 FIG. 4 shows a schematic diagram of the structure of the fire power adjustment dial 41 provided in this embodiment. Figure 8 Combined with Figure 2As shown, the fire power adjustment dial 41 is provided with a plurality of adjustment teeth spaced along its circumference; when the fire power adjustment paddle 422 is located at the middle position of the second fixed end 421, it can extend between two adjacent adjustment teeth, and when the fire power adjustment paddle 422 rotates the second preset angle, it can be disengaged from between the two adjacent adjustment teeth and reset. When the user rotates the firing knob 2, the valve stem 12 can drive the fire power adjustment dial 41 to rotate, so that the fire power adjustment paddle 422 can be disengaged from between the two adjacent adjustment teeth of the fire power adjustment dial 41 and reset after rotating the second preset angle. At this time, the controller of the gas stove adjusts the fire power of the gas stove to increase or decrease one gear. Preferably, the fire power paddle switch 42 is a two-way paddle switch. When the user rotates the firing knob 2 clockwise, the fire power gear increases, and when the user rotates the firing knob 2 counterclockwise, the fire power gear decreases, so as to meet cooking needs, improve the taste of cooked food, and enhance the user experience. It should be noted that the two-way paddle switch is a prior art, and the specific structure of the two-way paddle switch is not described in detail in this embodiment.

[0060] It should be noted that the middle position of the second fixed end 421 refers to the firepower adjustment paddle 422 being located at the "0 gear" of the second fixed end 421. When the firepower adjustment paddle 422 swings clockwise at the second preset angle, the firepower adjustment paddle 422 is located at the "1 gear" of the second fixed end 421. When the firepower adjustment paddle 422 swings counterclockwise at the second preset angle, the firepower adjustment paddle 422 is located at the "-1 gear" of the second fixed end 421. In this embodiment, when the firepower adjustment paddle 422 is set to be located at the "1 gear" of the second fixed end 421, the controller adjusts the firepower gear to increase; when the firepower adjustment paddle 422 is set to be located at the "-1 gear" of the second fixed end 421, the controller adjusts the firepower gear to decrease. Of course, in other embodiments, the corresponding relationship between the increase and decrease of the firepower gear and the position of the firepower adjustment paddle 422 can also be adjusted according to the installation position of the firepower paddle switch 42, and this embodiment does not limit this. In addition, the second preset angle is the angle at which the firepower adjustment paddle 422 swings from the "0 gear" of the second fixed end 421 to the "1 gear" or from the "0 gear" of the second fixed end 421 to the "-1 gear". This embodiment does not limit the specific value of the second preset angle, and designers can make adjustments based on the model of the firepower paddle switch 42 they choose.

[0061] like Figure 4 and Figure 8As shown, the cross section of the valve stem 12 is D-shaped, and a D-shaped hole 411 is provided on the fire power adjustment dial 41. The D-shaped hole 411 on the fire power adjustment dial 41 can cooperate with the valve stem 12 to achieve the connection between the fire power adjustment dial 41 and the valve stem 12, so that when the user turns the firing knob 2, the fire power adjustment dial 41 can be driven to rotate synchronously through the valve stem 12 to achieve precise adjustment of the fire power gear. It should be noted that the elastic member 313 can also play a role in limiting the fire power adjustment dial 41 to prevent the fire power adjustment dial 41 from moving along the axis direction of the valve stem 12, causing the fire power adjustment paddle 422 to disengage from the two adjacent adjustment teeth of the fire power adjustment dial 41, affecting the fire power gear adjustment.

[0062] The gas stove switch device provided in this embodiment has a simple structure design of the entire device, and the rotational force is transmitted by the mechanical structure. The electrical signal obtained in this process is accurate and reliable, and is easy to install. When the user presses and turns the ignition knob 2, the valve stem 12 can drive the firepower adjustment dial 41 to rotate, and at the same time drive the firepower adjustment paddle 422 to swing, so as to output an electrical signal to the controller to achieve firepower gear adjustment. When the user turns the ignition knob 2, the firepower adjustment dial 41 can move the firepower adjustment paddle 422, which can present a damping feeling and improve the user experience.
