[0002] The burner of a gas stove usually includes two air inlets, each of which is provided with a damper plate. Rotating the damper plate can change the ventilation area between the burner's air inlet and the external environment. In order to ensure the flexibility of adjustment, two sets of damper adjustment mechanisms are required to perform adjustment operations separately: one damper plate uses one set of damper adjustment mechanisms to realize the rotation of the corresponding damper plate, thereby realizing the adjustment of the ventilation area between the corresponding air inlet and the external environment; the other damper plate uses another set of damper adjustment mechanisms to realize the rotation of the corresponding damper plate, thereby realizing the adjustment of the ventilation area between the corresponding air inlet and the external environment.

[0016] In one embodiment, orthographic projections of the connection holes on at least two of the adjusting dials on the fixing plate do not overlap with each other.

[0017] In one embodiment, a limiting portion is provided on the adjusting dial, and the limiting portion is used to limit the transmission member to constrain the corresponding transmission member to rotate within a preset angle range.

[0043] Figure 1 FIG2 shows a schematic structural diagram of a burner, a damper regulator and a damper regulating mechanism 200 in an embodiment of the present application. Figure 2 A side view of a burner, a damper regulator, and a damper adjustment mechanism 200 in one embodiment of the present application is shown.

[0044] See Figure 1 and Figure 2 A gas stove 10 provided in one embodiment of the present application includes a burner and a valve body 130. The burner includes a burner head 110 and a valve body 130 connected to the burner head 110. The burner head 110 is supplied with gas via the valve body 130, and the amount of gas entering the burner head 110 is adjusted or changed via the valve body 130.

[0045] Please refer again Figure 1 , and refer to Figure 3The burner head 110 has two air inlets 1101 and an air flap 120 located at each air inlet 1101. The air flap 120 has an air inlet opening 1201. The air flap 120 can rotate relative to the corresponding air inlet 1101 to change the air inlet area of ​​the air inlet 1101, that is, to change the connection area between the air inlet opening 1201 and the air inlet 1101, thereby changing the ventilation area between the air inlet 1101 of the burner head 110 and the external environment, and thereby changing the air intake volume of the air inlet 1101 of the burner head 110.

[0046] Figure 4 A partial structural diagram of the damper adjustment mechanism 200 in one embodiment of the present application is shown.

[0047] Please refer again Figure 1 , and refer to Figure 4 The gas stove 10 further includes a damper adjustment mechanism 200 for the gas stove 10 .

[0048] Please refer again Figure 1 and Figure 4 An embodiment of the present application provides a damper adjustment mechanism 200 comprising a fixed plate 210, at least two transmission members spaced apart, and an adjustment assembly 230. The fixed plate 210 is mounted on the valve body 130. The at least two transmission members are rotatably connected to the fixed plate 210, each of which is in transmission connection with a corresponding damper 120. The adjustment assembly 230 is mounted on the fixed plate 210 and is configured to selectively be in transmission connection with one of the at least two transmission members. When the adjustment assembly 230 is in transmission connection with a transmission member, it drives the transmission member to rotate, thereby driving the corresponding damper 120 to rotate. This can change the air intake area of ​​the corresponding air inlet 1101, that is, change the ventilation area between the corresponding air inlet 1101 of the burner 110 and the external environment, and thus change the air intake volume of the corresponding air inlet 1101 of the burner 110. In this way, the air intake volume of at least two air inlets 1101 can be changed by using a single adjustment assembly 230, which saves components and reduces costs to a certain extent.

[0049] Further, please refer again to Figure 4 , and refer to Figure 5 and Figure 6 The adjustment component 230 includes an adjustment member 233 and at least two adjustment dials, wherein the adjustment dials are transmission-connected to the transmission member one by one, and the adjustment member 233 is constructed to be able to selectively connect to one of the at least two adjustment dials, so that the adjustment component 230 can be transmission-connected to one of the at least two transmission plates.

[0050] For details, please refer again to Figure 4 、 Figure 5 and Figure 6There are two transmission members, namely a first transmission member 223 and a second transmission member 224. The second transmission member 224 is spaced apart from the first transmission member 223. The first transmission member 223 is transmission-connected to one air flap 120, and the second transmission member 224 is transmission-connected to the other air flap 120. For ease of explanation, the air flap 120 transmission-connected to the first transmission member 223 is referred to as the first air flap 120, and the air inlet 1101 corresponding to the first air flap 120 is referred to as the first air inlet 1101; the air flap 120 transmission-connected to the second transmission member 224 is referred to as the second air flap 120, and the air inlet 1101 corresponding to the second air flap 120 is referred to as the second air inlet 1101. When the first transmission member 223 rotates, it drives the first air flap 120 to rotate, thereby changing the air volume entering the first air inlet 1101 of the burner 110. Similarly, when the second transmission member 224 rotates, it drives the second air flap 120 to rotate, thereby changing the air volume entering the second air inlet 1101 of the burner 110. Correspondingly, the adjustment member 233 is detachably connected to the first transmission member 223 or the second transmission member 224, so that the adjustment member 233 can be used to change the ventilation area between the corresponding air inlet 1101 of the burner 110 and the external environment. When the adjusting member 233 is in transmission connection with the first transmission member 223, rotating the adjusting member 233 can drive the first transmission member 223 to rotate, thereby driving the first air flap 120 to rotate, thereby changing the air intake of the first air inlet 1101 of the burner head 110; when the adjusting member 233 is in transmission connection with the second transmission member 224, rotating the adjusting member 233 can drive the second transmission member 224 to rotate, thereby driving the second air flap 120 to rotate, thereby changing the air intake of the second air inlet 1101 of the burner head 110; therefore, with the help of one adjusting member 233, the air intake of the two air inlets 1101 can be adjusted, which saves more parts and reduces costs to a certain extent.

[0051] In some embodiments, please refer again to Figure 4 、 Figure 5 and Figure 6The adjustment assembly 230 includes a first adjustment dial 231 and a second adjustment dial 232. The adjustment member 233 is detachably connected to the first adjustment dial 231 or the second adjustment dial 232. When the adjustment member 233 is connected to the first adjustment dial 231, the first adjustment dial 231 is in transmission connection with the first transmission member 223, and thus the adjustment member 233 can be in transmission connection with the first transmission member 223. At this time, rotating the adjustment member 233 can drive the first adjustment dial 231 and the first transmission member 223 to rotate, thereby driving the corresponding air flap 120 to rotate, that is, the first air flap 120 to rotate, thereby adjusting the air flow rate of the first air inlet 1101 of the stove head 110. Similarly, when the adjustment member 233 is connected to the second adjustment dial 232, the second adjustment dial 232 is in transmission connection with the second transmission member 224, thereby driving the second air flap 120 to rotate, thereby adjusting the air flow rate of the second air inlet 1101 of the stove head 110.

[0052] Optionally, refer again to Figure 6 The first adjusting member 231 is engaged with the first transmission member 223 , and the second adjusting member 232 is also engaged with the second transmission member 224 .

[0053] Optionally, refer again to Figure 4 The fixed plate 210 , the first adjusting member 231 and the second adjusting member 232 are all staggeredly installed on the valve stem 131 of the valve body 130 along the center line direction of the fixed plate 210 , so that the adjusting assembly 230 can be fixed on the fixed plate 210 .

[0054] Specifically, see Figure 7 、 Figure 8 and Figure 9 The fixing plate 210, the first adjusting dial 231 and the second adjusting dial 232 are all provided with mounting holes that match the valve stem 131. The mounting holes of the fixing plate 210, the first adjusting dial 231 and the second adjusting dial 232 are respectively the fixed mounting hole 2101, the first mounting hole 2311 and the second mounting hole 2321, so that the fixing plate 210, the first adjusting dial 231 and the second adjusting dial 232 are all staggeredly installed on the valve stem 131 of the valve body 130 along the center line direction of the fixing plate 210.

[0055] In some embodiments, the fixing plate 210 is provided with screw mounting holes 2102. Figure 7 In the illustrated embodiment, there are two screw mounting holes 2102 , so that the fixing plate 210 can be fixed to the valve body 130 by two screws.

[0056] Furthermore, the adjusting member 233 is detachably connected to the adjusting dial, so that the adjusting member 233 can be selectively connected to one of the at least two adjusting dials.

[0057] Further, see Figure 10 The adjusting member 233 has a connecting portion 2331. The adjusting member is provided with a connecting hole that matches the connecting portion 2331. The adjusting member 233 is detachably connected to the adjusting member via the connecting portion 2331 and the connecting hole, so that the adjusting member 233 can be selectively connected to one of the at least two adjusting members. The adjusting member 233 is selectively connected to one of the at least two adjusting members via the connecting portion 2331 and the connecting hole.

[0058] Furthermore, the orthographic projections of the connection holes on the at least two adjusting dials on the fixed plate 210 do not overlap with each other, ensuring that when the connecting portion 2331 is connected to one of the at least two adjusting dials, the connecting portion 2331 is not connected to the other adjusting dials, and they do not interfere with each other.

[0059] For details, please refer again to Figure 8 、 Figure 9 and Figure 10 The first adjusting member 231 is provided with a first connecting hole 2312 that cooperates with the connecting portion 2331, so that the adjusting member 233 is detachably connected to the first adjusting member 231. The second adjusting member 232 is provided with a second connecting hole 2322 that cooperates with the connecting portion 2331, so that the adjusting member 233 is detachably connected to the second adjusting member 232, so that the adjusting member 233 can be selectively connected to one of the first adjusting member 231 and the second adjusting member 232.

[0060] In some embodiments, the connecting portion 2331 is a connecting column, the second connecting hole 2322 and the first connecting hole 2312 are waist hole structures, and the length directions of the second connecting hole 2322 and the first connecting hole 2312 are perpendicular to the axial direction of the connecting column, which makes it easier to ensure the connection between the connecting portion 2331 and the second connecting hole 2322, as well as the connection between the connecting portion 2331 and the first connecting hole 2312.

[0061] Furthermore, a limiting portion is provided on the adjusting dial, and the limiting portion is used to limit the transmission member to constrain the corresponding transmission member to rotate within a preset angle range, and the travel of the transmission member is constrained by means of the limiting portion.

[0062] For details, please refer again to Figure 6 、 Figure 8 and Figure 9The first adjusting dial 231 is provided with a first limiting portion 2313, and the first limiting portion 2313 is used to rotate the first transmission member 223 within a first preset angle range; the second adjusting dial 232 is provided with a second limiting portion 2323, and the second limiting portion 2323 is used to rotate the second transmission member 224 within a second preset angle range; the rotation stroke of the first transmission member 223 and the second transmission member 224 can be limited, and then the rotation stroke of the corresponding air flap 120 can be limited, so as to facilitate the adjustment of the air intake volume of the air inlet 1101 of the burner 110 as needed.

[0063] In some embodiments, the first limiting portion 2313 and the second limiting portion 2323 are arranged according to the air inlet opening 1201. Figure 2 In the embodiment shown, the air inlet opening 1201 is an arc-shaped opening with a central angle of α1. Figure 8 and Figure 9 In the illustrated embodiment, the first limiting portion 2313 and the second limiting portion 2323 are both arc segments with convex teeth at a central angle α2. Correspondingly, the first preset angle range and the second preset angle range are both 0-α2, wherein α1 and α2 are both less than 90 degrees and α2 is not less than α1. The first limiting portion 2313 is formed by connecting a plurality of first convex teeth distributed circumferentially around the rotation axis of the first adjustment dial 231, and the second limiting portion 2323 is formed by connecting a plurality of second convex teeth distributed circumferentially around the rotation axis of the second adjustment dial 232. The first limiting portion 2313 and the second limiting portion 2323 can be used to drive the corresponding air flap 120 to rotate α2 to ensure that the air inlet opening 1201 is completely closed; the first limiting portion 2313 and the second limiting portion 2323 can be used to drive the corresponding air flap 120 to rotate in the opposite direction by the same angle to achieve full opening of the air inlet opening 1201; the first limiting portion 2313 and the second limiting portion 2323 can be used to drive the corresponding air flap 120 to rotate an angle less than α1 to achieve partial closure of the air inlet opening 1201.

[0064] Furthermore, the gas stove 10 further includes a stove panel located on one side of the fixing plate 210, please refer to Figure 1The adjustment assembly 230 further includes an adjustment knob 234 disposed on the cooktop. The adjustment knob 234 is mounted on the adjustment member 233. The adjustment knob 234 drives the adjustment member 233 to rotate, thereby adjusting the air flow rate of the corresponding air inlet 1101 of the burner 110. Furthermore, since the adjustment knob 234 is disposed on the cooktop, the adjustment operation is convenient. Furthermore, since the air flow rate of both air inlets 1101 can be adjusted using a single adjustment knob 234, only one mounting opening corresponding to the adjustment knob 234 is required on the cooktop. This allows the adjustment knob 234 to be displaced relative to the mounting opening along its centerline, thereby reducing the number of mounting openings required (in the prior art, two mounting openings are required due to the two sets of damper adjustment mechanisms). This, to a certain extent, helps improve the sealing performance of the cooktop.

[0065] Furthermore, at least two transmission members are staggered in a direction parallel to the rotation axis of the transmission member, so that the transmission members do not interfere with each other when performing transmission operations.

[0066] Specifically, the second transmission member 224 and the first transmission member 223 are arranged offset along the rotation axis of the first transmission member 223 or the second transmission member 224. When the adjusting member 233 is in transmission connection with the first transmission member 223, the adjusting member 233 can drive the first transmission member 223 to rotate, thereby driving the first air flap 120 to rotate, thereby adjusting the air flow rate of the first air inlet 1101 of the furnace head 110. During this process, because the second transmission member 224 and the first transmission member 223 are arranged offset along the rotation axis of the first transmission member 223 or the second transmission member 224, the second transmission member 224 will not rotate, and accordingly, the second air flap 120 will not rotate either. When the adjusting member 233 is in transmission connection with the second transmission member 224, the adjusting member 233 can drive the second transmission member 224 to rotate, thereby driving the second air flap 120 to rotate, thereby realizing the adjustment of the air intake volume of the second air inlet 1101 of the stove head 110. Similarly, during this process, the first transmission member 223 will not rotate, and correspondingly, the first air flap 120 will not rotate either; that is, the adjusting member 233 is used to realize the independent adjustment of the air intake volume of the two air inlets 1101, without interfering with each other, and with higher flexibility.

[0067] Furthermore, the transmission member is detachably provided on the fixed plate 210 and can rotate relative to the fixed plate 210 , so that at least two transmission members can be staggered along the rotation axis of the transmission member as needed.

[0068] In some embodiments, please refer again to Figure 5The damper adjustment mechanism 200 also includes a first adjustment shaft 221 for installing a first transmission member 223, and a second adjustment shaft 222 for installing a second transmission member 224, wherein the first adjustment shaft 221 and the second adjustment shaft 222 are both detachably arranged on the fixed plate 210, and the first adjustment shaft 221 and the second adjustment shaft 222 are both rotatable relative to the fixed plate 210. The second transmission member 224 and the first transmission member 223 can be staggered along the direction of the rotation axis of the first transmission member 223 or the second transmission member 224, and then the first adjustment shaft 221 and the second adjustment shaft 222 are rotatably installed on the fixed plate 210.

[0069] Further, please refer again to Figure 5 , and refer to Figure 11 The damper adjustment mechanism 200 further includes two clamps 225. A first limiting groove 2211 is provided on the first adjustment shaft 221, which cooperates with the first clamp 225. A second limiting groove 2221 is provided on the second adjustment shaft 222, which cooperates with the second clamp 225. The first limiting groove 2211 and the first clamp 225 are used to limit the axial displacement of the first adjustment shaft 221, while the second limiting groove 2221 and the second clamp 225 cooperate to limit the axial displacement of the second adjustment shaft 222. This allows the first and second adjustment shafts 221 and 222 to rotate relative to the fixed plate 210 and be detachably mounted on the fixed plate 210, facilitating the staggered arrangement of the second transmission member 224 on the second adjustment shaft 222 and the first transmission member 223 on the first adjustment shaft 221 along the rotation axis of the first transmission member 223 or the second transmission member 224. The direction of the rotation axis of the first transmission member 223 or the second transmission member 224 is parallel to the axial direction of the first adjustment shaft 221 and also parallel to the axial direction of the second adjustment shaft 222 .

[0070] Further, please refer again to Figure 7 The fixing plate 210 is provided with a first positioning hole 2103 and a second positioning hole 2104 spaced apart from each other. The first adjustment shaft 221 can be rotatably engaged with the first positioning hole 2103, and the second adjustment shaft 222 can be rotatably engaged with the second positioning hole 2104, so that the first adjustment shaft 221 and the second adjustment shaft 222 can be rotatably mounted on the fixing plate 210. The rotation axis direction of the first transmission member 223, the rotation axis direction of the second transmission member 224, the axial direction of the first positioning hole 2103, and the axial direction of the second positioning hole 2104 are all parallel to the centerline direction of the fixing plate 210.

[0071] Furthermore, the two clamps 225 have different sizes, and correspondingly, the sizes of the first limit groove 2211 and the second limit groove 2221 are also different, which facilitates differentiated installation, and facilitates the quick rotational installation of the first adjustment shaft 221 on the fixed plate 210 through the first clamp 225, and also facilitates the quick rotational installation of the second adjustment shaft 222 on the fixed plate 210 through the second clamp 225, and makes the first adjustment shaft 221 and the second adjustment shaft 222 staggered on the fixed plate 210 along the center line direction of the fixed plate 210, so that the second transmission member 224 and the first transmission member 223 are staggered along the rotation axis direction of the first transmission member 223 or the second transmission member 224.

[0072] In some embodiments, the first adjustment shaft 221 and the second adjustment shaft 222 have the same structure. Figure 11 The first and second adjusting shafts 221, 222 are provided with a first limiting groove 2211 and a second limiting groove 2221 spaced apart from each other, facilitating the simultaneous mass production of the first and second adjusting shafts 221, 222.
