Description

Technical Field

[0001] This utility model relates to the field of stoves, and in particular to a gas valve and a stove burner. Background Technology

[0002] Most existing stir-fry modes rely on a strong suction valve and buttons to control the opening and closing of the stir-fry channel. However, this mode has two major drawbacks: firstly, it has high energy consumption because the strong suction valve needs mains power, and the bistable valve increases battery power consumption; secondly, the user experience of the panel buttons is poor, for example, if the panel gets dirty, the buttons are prone to malfunction.

[0003] In light of this, engineers designed a new gas valve structure that allows the user to manually press a valve stem to open the high-power valve. Specifically, a control rod extending above the cooktop panel is connected to the upper end of the valve core of the high-power valve. Pressing down the control rod moves the valve core downwards, thus opening or closing the high-power valve. The high-power valve can be held in an engaged state by magnetic force or a thermocouple, thereby maintaining its open state.

[0004] However, in early designs, the cooktop panel required an exposed control lever for the high-powered valve, in addition to the standard rotary valve control knob. This design not only affected the aesthetics but also made it easier for external impurities to penetrate the cooktop due to the through-hole for the high-powered valve control lever. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a gas valve and a stove burner.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] A gas valve,

[0008] The gas valve includes a plug valve, a stir-fry valve, and a linkage assembly;

[0009] The stopcock valve includes a first valve stem, a first valve core, and a control knob. The first valve stem extends vertically, with its lower end extending below the cooktop panel and connected to the first valve core, and its upper end extending above the cooktop panel and connected to the control knob.

[0010] The stir-fry valve includes a second valve stem and a second valve core. The second valve stem extends vertically and is located below the cooktop panel. The lower end of the second valve stem is connected to the second valve core.

[0011] The cooktop panel has a first through hole for the first valve stem to pass through. The upper end of the linkage component extends above the cooktop panel, and the lower end of the linkage component extends below the cooktop panel through the first through hole. The linkage component includes a first pressure plate and a connecting part. The first pressure plate is located below the control knob and above the cooktop panel. The first pressure plate has a gap with the cooktop panel in the vertical direction. The projection of the control knob on the first pressure plate in the vertical direction at least partially overlaps with the first pressure plate. The connecting part is fixedly connected to the first pressure plate. The lower end of the connecting part extends below the cooktop panel. The connecting part acts on the upper end of the second valve stem. The connecting part can move with the first pressure plate in the vertical direction to press the second valve stem.

[0012] In this design, the control of the stopcock valve and the stir-fry valve is integrated into the control knob. A linkage component allows the control knob, which originally only controlled the opening and closing of the stopcock valve, to simultaneously open the stir-fry valve. When the control knob is pressed down, it presses the first pressure plate located below it, causing the first pressure plate to move the connecting part downwards. The gap between the first pressure plate and the cooktop panel provides space for the first pressure plate to move. After the connecting part moves downwards, it presses the second valve stem, thus opening the stir-fry valve. The linkage component and the first valve stem share the same first through hole on the cooktop panel. The second valve stem is located below the cooktop panel, eliminating the need for a separate through hole for the second valve stem to pass through, reducing the risk of external impurities falling into the cooktop, and also making the cooktop more aesthetically pleasing.

[0013] Preferably, the first pressure plate is an annular plate, and the first pressure plate is sleeved on the outer periphery of the first valve stem.

[0014] In this design, the annular plate increases the contact area between the first pressure plate and the control knob, enabling the control knob to press the first pressure plate stably and improving the reliability of opening the stir-fry valve via the control knob.

[0015] Preferably, the connecting portion further includes a first protrusion and a connecting rod;

[0016] The first pressure plate is connected to the upper end of the first protrusion and extends radially toward the outside of the first protrusion along the first valve stem. The lower end of the first protrusion extends into the first through hole, and a second through hole is formed inside the first protrusion for the first valve stem to pass through.

[0017] The two ends of the connecting rod are fixedly connected to the first protrusion and the second valve stem, respectively, and the lower end face of the control knob has a gap in the vertical direction with the upper end face of the first pressure plate.

[0018] In this design, the first protrusion facilitates the connection between the first pressure plate and the connecting rod, and also partially blocks the first through hole, reducing the exposed area of ​​the first through hole and further reducing the risk of external impurities falling into the stove. The control knob and the first pressure plate are vertically spaced to prevent accidental activation of the first pressure plate when the control knob is pressed down to open the gas passage of the stopcock valve, thus preventing the stir-fry valve from opening unexpectedly.

[0019] Preferably, the end of the connecting rod connected to the first protrusion is provided with a third through hole, the first protrusion extends into the third through hole, and the outer peripheral wall of the first protrusion abuts against the inner peripheral wall of the third through hole.

[0020] In this solution, the above-mentioned configuration allows the outer diameter of the first protrusion to be designed to be smaller, thereby allowing the diameter of the first through hole on the cooktop panel to be designed to be smaller, or the area of ​​the first pressure plate to be designed to be larger, thereby better blocking the first through hole and reducing the risk of external impurities falling into the cooktop.

[0021] Preferably, the connecting rod includes a connecting rod body and a second protrusion. The second protrusion is disposed at one end of the connecting rod body near the first protrusion. The lower end of the second protrusion is connected to the connecting rod. The third through hole is formed in the second protrusion. The upper end of the second protrusion extends into the interior of the first through hole and is connected to the first protrusion.

[0022] And / or, the connecting rod includes a connecting rod body and a third protrusion, the third protrusion being disposed at one end of the connecting rod body near the second valve rod, the interior of the third protrusion forming a connecting hole, the lower end of the connecting hole being through, the second valve rod extending into the connecting hole, and the outer peripheral wall of the second valve rod abutting against the inner peripheral wall of the connecting hole.

[0023] In this design, the second protrusion extends into the first through hole. On one hand, it partially blocks the first through hole, reducing the exposed area and lowering the risk of external impurities falling into the cooktop. On the other hand, the second protrusion reduces the gap between the first protrusion and the wall of the first through hole, minimizing the amount of movement the first protrusion can make within the through hole and ensuring the stability of the linkage assembly on the cooktop panel.

[0024] Preferably, the vertical distance between the lower end face of the control knob and the upper end face of the first pressure plate is greater than or equal to 4 mm.

[0025] In this design, since the control knob also needs to be pressed down during the ignition phase to open the gas passage in the stopcock valve, the distance between the control knob and the first pressure plate is designed to be greater than or equal to a certain value to prevent the first pressure plate from being accidentally touched when the control knob is pressed down for ignition, thus avoiding the accidental opening of the ignition valve.

[0026] Preferably, the connecting part includes a support rod and a second pressure plate. The second pressure plate is located below the cooktop panel and above the second valve stem. The upper end of the support rod passes through the first through hole and is connected to the first pressure plate. The lower end of the support rod is connected to the second pressure plate. The support rod has a fourth through hole through which the first valve stem passes. The lower end face of the second pressure plate and the upper end face of the second valve stem have a gap in the vertical direction. The projection of the second valve stem onto the second pressure plate in the vertical direction at least partially coincides with the second pressure plate.

[0027] In this design, the second pressure plate is fixedly connected to the first pressure plate via a support rod. When the first pressure plate moves downward, it will cause the second pressure plate connected to it to move downward, thereby pressing the second valve rod located below the second pressure plate and opening the stir-fry valve.

[0028] Preferably, the gas valve further includes a sealing ring, which is sleeved on the outer periphery of the support rod and located in the vertical direction between the first pressure plate and the second pressure plate, and the sealing ring extends at least partially into the first through hole;

[0029] And / or, the lower end face of the control knob and the upper end face of the first pressure plate have a gap in the vertical direction;

[0030] And / or, the second pressure plate is an annular plate, and the second pressure plate is sleeved on the outer periphery of the support rod.

[0031] In this design, a sealing ring is used to further seal the gap between the support rod and the wall of the first through hole. This reduces the exposed area of ​​the first through hole, lowering the risk of external impurities falling into the cooktop. Furthermore, the sealing ring reduces the gap between the support rod and the wall of the first through hole, minimizing the range of motion of the support rod within the first through hole and ensuring the stability of the linkage assembly on the cooktop panel. The control knob and the first pressure plate are vertically spaced to prevent accidental activation of the first pressure plate when the control knob is pressed down to open the gas passage of the stopcock valve, thus preventing the stir-fry valve from opening unintentionally. The annular second pressure plate has a simple structure, requires low precision in its fit with the second valve stem, is easy to install, and has a high success rate in pressing the second valve stem, improving the reliability of opening the stir-fry valve via the control knob.

[0032] Preferably, the linkage assembly further includes a reset member, which is located below the second pressure plate. The reset member has two ends in the vertical direction that abut against the second pressure plate and the first valve body of the plug valve, respectively. The reset member is used to apply a vertically upward force to the second pressure plate.

[0033] In this solution, the reset component is used to automatically reset the linkage component, eliminating the need for the user to pull the linkage component upwards, making operation more convenient, and also preventing the stir-fry valve from remaining in the open state due to the user forgetting to pull the linkage component upwards.

[0034] A stove burner, the stove burner including the gas valve as described above.

[0035] The significant advantages of this invention are as follows: It integrates the control of the stopcock valve and the high-power valve onto a single control knob. Through a linkage component, the control knob, which previously only controlled the opening and closing of the stopcock valve, can now simultaneously control the opening of the high-power valve. When the control knob is pressed down, it presses the first pressure plate located below it, causing the connecting part to move downwards. The gap between the first pressure plate and the cooktop panel provides space for the first pressure plate to move. After the connecting part moves downwards, it presses the second valve stem, thus opening the high-power valve. The linkage component and the first valve stem share the same first through hole on the cooktop panel. The second valve stem is located below the cooktop panel, eliminating the need for a separate through hole for the second valve stem to pass through, reducing the risk of external impurities falling into the cooktop, and also making the cooktop more aesthetically pleasing.

[0076] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0077] Example 1

[0078] like Figures 1-3 As shown, this embodiment discloses a stove, including a stove burner 11, a stove panel 12 and a base 13. The stove burner 11 is fixed on the base 13, and the stove panel 12 covers the opening at the upper end of the base 13 to seal the space inside the base 13, thereby protecting the stove burner 11 structure set inside the base 13.

[0079] like Figure 2 and Figure 3 As shown, the stove burner 11 includes a gas valve, which includes a stop valve 2, a stir-fry valve 3, and a linkage component 4. The stop valve 2 is used to open the flame of the stove burner 11 and can adjust the flame intensity of the burner cap. The stir-fry valve 3 is used to open and close the stir-fry mode for cooking. The linkage component 4 is used to achieve linkage control between the stop valve 2 and the stir-fry valve 3.

[0080] like Figure 3 and Figure 4 As shown, the stopcock valve 2 includes a first valve body 21, a first valve stem 22, a first valve core 23, and a control knob 24. The first valve core 23 is located inside the first valve body 21. The first valve stem 22 extends vertically, and the cooktop panel 12 has a first through hole 121 through which the first valve stem 22 passes. The lower end of the first valve stem 22 passes through the first through hole 121, extends to the bottom of the cooktop panel 12, and connects to the first valve core 23. The upper end of the first valve stem 22 passes through the first through hole 121, extends to the top of the cooktop panel 12, and connects to the control knob 24. The user can press down the control knob 24 to press down the first valve stem 22 connected to the control knob 24, thereby opening the gas passage in the stopcock valve 2, allowing gas to flow and ignite the flame. The user can rotate the control knob 24 to rotate the first valve stem 22 connected to the control knob 24, thereby rotating the first valve core 23 connected to the first valve stem 22 to adjust the flame intensity.

[0081] The specific method by which the first valve stem 22 is pressed down to open the gas passage in the plug valve 2 is existing technology and will not be described in detail here.

[0082] like Figure 3 and Figure 4As shown, in this embodiment, the stir-fry valve 3 is located entirely below the cooktop panel 12. The stir-fry valve 3 includes a second valve body 31, a second valve stem 32, and a second valve core 33. The second valve core 33 is located inside the second valve body 31. The second valve stem 32 extends vertically, with its lower end extending into the interior of the second valve body 31 and connecting to the second valve core 33. The upper end of the second valve stem 32 extends upward to the outside of the second valve body 31 but does not exceed the cooktop panel 12. The user can open the stir-fry valve 3 by pressing down on the second valve stem 32.

[0083] In this embodiment, the stir-fry valve 3 is opened by the user manually pressing the mechanical structure. After the stir-fry valve 3 is opened, it can be maintained in the open state by magnetic adsorption or thermocouple adsorption.

[0084] like Figures 2-6 As shown, the upper end of the linkage component 4 extends above the cooktop panel 12, and the lower end of the linkage component 4 extends below the cooktop panel 12 through the first through hole 121. The linkage component 4 includes a first pressure plate 41 and a connecting portion 42.

[0085] like Figures 2-5 As shown, the first pressure plate 41 is located below the control knob 24 and above the cooktop panel 12. The first pressure plate 41 has a gap with the cooktop panel 12 in the vertical direction. The projection of the control knob 24 on the first pressure plate 41 in the vertical direction at least partially overlaps with the first pressure plate 41, so that the control knob 24 can abut against the first pressure plate 41 during the pressing process, thereby driving the first pressure plate 41 to move downward. The gap between the first pressure plate 41 and the cooktop panel 12 in the vertical direction provides space for the first pressure plate 41 to move in the vertical direction.

[0086] In this embodiment, the specific value of the distance between the first pressure plate 41 and the stove panel 12 in the vertical direction is not limited. It can be designed according to the actual situation, at least ensuring that the stir-fry valve 3 can be fully opened when the first pressure plate 41 moves downward to the extreme position.

[0087] Specifically, such as Figures 3-5 As shown, in this embodiment, the first pressure plate 41 is an annular plate, which is sleeved on the outer periphery of the first valve stem 22. The control knob 24 is a hollow structure with an open lower end. The projection of the lower end surface of the peripheral sidewall of the control knob 24 onto the first pressure plate 41 in the vertical direction completely overlaps with the first pressure plate 41. The annular plate design increases the contact area between the first pressure plate 41 and the control knob 24, allowing the control knob 24 to stably press the first pressure plate 41 and improving the reliability of opening the stir-fry valve 3 via the control knob 24.

[0088] In other alternative embodiments, the projection of the lower end face of the peripheral sidewall of the control knob 24 onto the first pressure plate 41 in the vertical direction may only partially overlap with the first pressure plate 41, so as to achieve contact between the control knob 24 and the first pressure plate 41.

[0089] Furthermore, such as Figure 3 As shown, the diameter of the first pressure plate 41 is larger than the diameter of the control knob 24, which effectively ensures that the projection of the lower end face of the peripheral sidewall of the control knob 24 onto the first pressure plate 41 in the vertical direction completely overlaps with the first pressure plate 41.

[0090] like Figures 2-6 As shown, the connecting part 42 is fixedly connected to the first pressure plate 41. The lower end of the connecting part 42 extends to the bottom of the cooktop panel 12. The connecting part 42 acts on the upper end of the second valve stem 32. The connecting part 42 can move vertically along with the first pressure plate 41 to press the second valve stem 32. The connecting part 42 includes a first protrusion 421 and a connecting rod 422.

[0091] like Figure 3 and Figure 5 As shown, the first protrusion 421 is also an annular structure. The first pressure plate 41 is connected to the upper end of the first protrusion 421. The first protrusion 421 is located at the center of the first pressure plate 41. The first pressure plate 41 extends radially outward from the first protrusion 421 along the first valve stem 22. The lower end of the first protrusion 421 extends into the first through hole 121. A second through hole 4211 is formed inside the first protrusion 421 for the first valve stem 22 to pass through. In this embodiment, the first pressure plate 41 and the first protrusion 421 are integrally formed. The second through hole 4211 penetrates both the first pressure plate 41 and the first protrusion 421 in the vertical direction, so that the first valve stem 22 can pass through.

[0092] In this embodiment, the first protrusion 421 facilitates the connection between the first pressure plate 41 and the connecting rod 422, and also blocks part of the first through hole 121, reducing the exposed area of ​​the first through hole 121 and further reducing the risk of external impurities falling into the stove.

[0093] In other alternative embodiments, the first pressure plate 41 and the first protrusion 421 may not be annular, in which case the first pressure plate 41 and the first protrusion 421 are not designed with through holes for the first valve stem 22 to pass through.

[0094] like Figure 3 , Figure 4 and Figure 6As shown, the two ends of the connecting rod 422 are fixedly connected to the first protrusion 421 and the second valve stem 32, respectively. The connecting rod 422 includes a connecting rod body 4221, a second protrusion 4222, and a third protrusion 4224. The second protrusion 4222 is located at the end of the connecting rod body 4221 near the first protrusion 421, and its lower end is connected to the connecting rod 422. The third protrusion 4224 is located at the end of the connecting rod body 4221 near the second valve stem 32. The second protrusion 4222 has a third through hole 4223, into which the first protrusion 421 extends, with its outer peripheral wall abutting against the inner peripheral wall of the third through hole 4223. The third protrusion 4224 has a connecting hole 4225 inside, into which the second valve stem 32 extends, with its outer peripheral wall abutting against the inner peripheral wall of the connecting hole 4225.

[0095] Among them, such as Figure 3 As shown, in this embodiment, the connecting hole 4225 is a through hole structure with both the upper and lower ends connected. In other alternative embodiments, the connecting hole 4225 may also be a blind hole structure with only the lower end connected.

[0096] In this embodiment, the diameter of the first protrusion 421 is designed to be smaller than the diameter of the second protrusion 4222, so that the outer diameter of the first protrusion 421 can be designed to be smaller, thereby allowing the diameter of the first through hole 121 on the cooktop panel 12 to be designed to be smaller, or the area of ​​the first pressure plate 41 can be designed to be larger, thereby better blocking the first through hole 121 and reducing the risk of external impurities falling into the cooktop.

[0097] In this embodiment, the outer peripheral wall of the first protrusion 421 and the inner peripheral wall of the third through hole 4223, as well as the outer peripheral wall of the second valve stem 32 and the inner peripheral wall of the connecting hole 4225, can be fixed by means of threaded connection, adhesive, etc., so as to realize the connection between the connecting rod 422 and the first protrusion 421 and the connection between the connecting rod 422 and the second valve stem 32.

[0098] In other alternative embodiments, the connecting rod 422 may not include the second protrusion 4222 and / or the third protrusion 4224, that is, the connecting rod 422 may only include the connecting rod body 4221 or the connecting rod body 4221 may only have the second protrusion 4222 or the third protrusion 4224 at one end. In this embodiment, providing the second protrusion 4222 and the third protrusion 4224 at both ends of the connecting rod body 4221 can increase the contact area between the connecting rod 422 and the first protrusion 421 and the contact area between the connecting rod 422 and the second valve stem 32, thereby increasing the connection strength. However, when the second protrusion 4222 or the third protrusion 4224 is not provided on one side of the connecting rod body 4221, the third through hole 4223 or the connecting hole 4225 is directly formed on the connecting rod body 4221.

[0099] Furthermore, such as Figure 3 As shown, the upper end of the second protrusion 4222 extends into the interior of the first through hole 121. On one hand, the second protrusion 4222 can partially block the first through hole 121, reducing the exposed area of ​​the first through hole 121 and lowering the risk of external impurities falling into the stove. On the other hand, the second protrusion 4222 can reduce the gap between the first protrusion 421 and the wall of the first through hole 121, reducing the amplitude of the first protrusion 421's movement within the first through hole 121 and ensuring the stability of the linkage assembly 4 installed on the stove panel 12.

[0100] During the ignition phase, the control knob 24 also needs to be pressed down to open the gas passage in the stopcock valve 2. Therefore, to prevent the first pressure plate 41 from being accidentally touched when the control knob 24 is pressed down for ignition, and to avoid the accidental opening of the ignition valve 3, as follows: Figure 3 As shown, the lower end face of the control knob 24 and the upper end face of the first pressure plate 41 have a gap in the vertical direction to reserve the movement space required for the control knob 24 to open the gas passage in the plug valve 2.

[0101] Among them, such as Figure 2 As shown, in this embodiment, the vertical distance 'a' between the lower end face of the control knob 24 and the upper end face of the first pressure plate 41 is greater than or equal to 4 mm. In other alternative embodiments, the vertical distance between the lower end face of the control knob 24 and the upper end face of the first pressure plate 41 can also be designed to be other vertical distances, depending on actual needs.

[0102] In this embodiment, the control of the stopcock valve 2 and the stir-fry valve 3 is integrated into the control knob 24. Through the linkage component 4, the control knob 24, which originally only controls the opening and closing of the stopcock valve 2, can simultaneously open the stir-fry valve 3. When the control knob 24 is pressed down, it presses the first pressure plate 41 located below it, causing the first pressure plate 41 to move the connecting part 42 downwards. The gap between the first pressure plate 41 and the cooktop panel 12 provides space for the first pressure plate 41 to move. After the connecting part 42 moves downwards, it presses the second valve stem 32, thereby opening the stir-fry valve 3. The linkage component 4 and the first valve stem 22 share the same first through hole 121 on the cooktop panel 12. The second valve stem 32 is located below the cooktop panel 12, eliminating the need for a separate through hole on the cooktop panel 12 for the second valve stem 32 to pass through, reducing the risk of external impurities falling into the cooktop and making the cooktop more aesthetically pleasing overall.

[0103] Furthermore, in this embodiment, when it is necessary to reset the stir-fry valve 3 from the open state to the closed state, the user can directly and manually pull the first pressure plate 41 upward. The first pressure plate 41 moves upward, driving the connecting part 42 connected to it and the second valve stem 32 connected to the connecting part 42 to move upward, so that the second valve core 33 is reset, and the stir-fry valve 3 can be reset from the open state to the closed state. In addition, as Figure 3 As shown, the second valve body 31 of the stir-fry valve 3 is usually also provided with a reset structure 34 for realizing the upward reset of the second valve core 33. The reset structure 34 pushes the second valve core 33 upward, which in turn drives the second valve rod 32 connected to the second valve core 33 to move upward. The second valve rod 32 can then drive the linkage component 4 connected to it to move upward, thereby realizing the reset of the first pressure plate 41.

[0104] The reset structure 34 of the stir-fry valve 3 is existing technology and will not be described in detail here.

[0105] Example 2

[0106] The stove in this embodiment is basically the same as the stove in embodiment 1, except that the structure of the connecting part 42 is different.

[0107] Specifically, such as Figures 7-9 As shown, the connecting part 42 includes a support rod 423 and a second pressure plate 424. The second pressure plate 424 is located below the cooktop panel 12 and above the second valve stem 32. The upper end of the support rod 423 passes through the first through hole 121 and connects to the first pressure plate 41, while the lower end of the support rod 423 connects to the second pressure plate 424. In this embodiment, the support rod 423 is sleeved on the outer periphery of the first valve stem 22, and the interior of the support rod 423 has a fourth through hole 4231 through which the first valve stem 22 passes. The lower end face of the second pressure plate 424 and the upper end face of the second valve stem 32 have a gap in the vertical direction, and the projection of the second valve stem 32 onto the second pressure plate 424 in the vertical direction at least partially coincides with the second pressure plate 424.

[0108] In this embodiment, the second pressure plate 424 is fixedly connected to the first pressure plate 41 via a support rod 423. When the first pressure plate 41 moves downward, it will drive the second pressure plate 424 connected to it to move downward, thereby pressing the second valve rod 32 located below the second pressure plate 424 and opening the stir-fry valve 3.

[0109] In this embodiment, the second pressure plate 424 is an annular plate, which is sleeved on the outer periphery of the support rod 423. The annular second pressure plate 424 has a simple structure, low precision requirements for fitting with the second valve rod 32, low installation difficulty, and a high success rate in pressing the second valve rod 32 with the second pressure plate 424, thereby improving the reliability of opening the stir-fry valve 3 by operating the knob 24.

[0110] In other alternative embodiments, the second pressure plate 424 may also be of other shapes, for example, fixed to one side of the support rod 423.

[0111] Furthermore, such as Figure 7 and Figure 8 As shown, the lower end face of the control knob 24 and the upper end face of the first pressure plate 41 have a gap in the vertical direction, so that the control knob 24 will not accidentally touch the first pressure plate 41 when it is pressed down to open the gas passage of the plug valve 2, thus preventing the stir-fry valve 3 from being opened accidentally.

[0112] Because there is a gap between the second pressure plate 424 and the second valve stem 32 in the vertical direction in this embodiment, the control knob 24 needs to push the first pressure plate 41 down a certain distance before the second pressure plate 424 will act on the second valve stem 32. Therefore, in this embodiment, the vertical distance between the lower end face of the control knob 24 and the upper end face of the first pressure plate 41 can be smaller than the vertical distance between the lower end face of the control knob 24 and the upper end face of the first pressure plate 41 in Embodiment 1.

[0113] In other alternative embodiments, the lower end face of the control knob 24 and the upper end face of the first pressure plate 41 may not be spaced apart in the vertical direction.

[0114] like Figure 7 and Figure 8 As shown, the linkage assembly 4 also includes a reset member 425, which is located below the second pressure plate 424. The reset member 425 has two ends in the vertical direction that abut against the second pressure plate 424 and the first valve body 21 of the plug valve 2, respectively. The reset member 425 applies a vertically upward force to the second pressure plate 424, causing the second pressure plate 424 to move upward, thereby driving the connected first pressure plate 41 to move upward and resetting the first pressure plate 41. Specifically, in this embodiment, the reset member 425 is a spring, relying on the spring force to reset the first pressure plate 41.

[0115] In this embodiment, the reset component 425 is used to realize the automatic reset of the linkage component 4, so that the user does not need to pull the linkage component 4 upward, making the operation more convenient, and also avoiding the situation where the user forgets to pull the linkage component 4 upward, causing the stir-fry valve 3 to always be in the open state.

[0116] In other alternative implementations, the user can also manually lift the first pressure plate 41 upwards to reset the first pressure plate 41.

[0117] Furthermore, such as Figure 7As shown, the gas valve also includes a sealing ring 5, which is sleeved on the outer periphery of the support rod 423 and located vertically between the first pressure plate 41 and the second pressure plate 424. The sealing ring 5 extends at least partially into the first through hole 121. The sealing ring 5 is used to further seal the gap between the support rod 423 and the hole wall of the first through hole 121, thereby reducing the exposed area of ​​the first through hole 121 and lowering the risk of external impurities falling into the stove. On the other hand, the sealing ring 5 can reduce the gap between the support rod 423 and the hole wall of the first through hole 121, reducing the amplitude of the support rod 423's movement within the first through hole 121 and ensuring the stability of the linkage assembly 4 on the stove panel 12.

[0118] In other alternative embodiments, the sealing ring 5 may be omitted, and the diameter of the support rod 423 may be designed to be larger. In this embodiment, the design of the sealing ring 5 also allows for a smaller size for the support rod 423, reducing its weight and facilitating the automatic reset of the first pressure plate 41 by the reset component 425.
