TECHNICAL FIELD

[0001] The utility model relates to knob assembly technical field, specifically, relate to a switch assembly and cooking equipment. BACKGROUND

[0002] In the case that the cooking equipment has multiple cooking zones, a switch component needs to be set for each cooking zone, and when the user uses multiple cooking zones at the same time, the user needs to adjust the gears of multiple switch components in sequence, which brings inconvenience to the user's use of the cooking equipment. SUMMARY

[0003] The utility model aims at solving one of the technical problems existing in the prior art or related art.

[0004] Therefore, in a first aspect, the utility model provides a switch assembly, which comprises: a base, a limiting portion being arranged on the base; at least two knob assemblies, which are arranged on the base; a linkage member, which is connected to adjacent two knob assemblies, and the adjacent two knob assemblies are interconnected through the linkage member, and the linkage member can move relative to the base; and the at least two knob assemblies include a first knob assembly, when the first knob assembly rotates towards a first direction, the gear of the first knob assembly is increased, and when the first knob assembly reaches the maximum gear, the limiting portion limits the linkage member, so that the linkage member limits the rotation of the first knob assembly towards the first direction.

[0005] The user can rotate the knob assembly, change the gear of the knob assembly by rotating the knob assembly, and make the cooking zone corresponding to the knob assembly realize the heating function at different power. Different knob assemblies can be interconnected through the linkage member, and the gears of adjacent two knob assemblies are interconnected. When the user uses the at least two knob assemblies, the gears of other knob assemblies can be adjusted correspondingly when the gear of one knob assembly is adjusted, and when the user uses multiple cooking zones of the cooking equipment at the same time, the gears of multiple knob assemblies do not need to be adjusted in sequence, which provides convenience for the user's use of the cooking equipment.

[0006] One of the at least two knob assemblies is set as the first knob assembly, the gear of the first knob assembly is increased when the first knob assembly rotates towards the first direction, and the first direction can be the clockwise direction or the counterclockwise direction. When the first knob assembly rotates to the maximum gear, the limiting portion on the base limits the linkage member, the limiting portion limits the movement of the linkage member relative to the base, and since the first knob assembly and the linkage member have the interlocking relationship, when the linkage member cannot continue to move, the first knob assembly also cannot continue to rotate towards the first direction.

[0007] The linkage member limits the knob assembly, without the need to set a limiting structure between the knob assembly and the base, and the linkage member can realize linkage function and limiting function, and when multiple functions are realized by the linkage member, the structure of the switch assembly is simplified, and the processing difficulty of the switch assembly is reduced.

[0008] In addition, the switch assembly according to the technical scheme provided in the utility model can also have the following additional technical features.

[0009] In some technical schemes, the linkage member is provided with a sliding groove, and the limiting part extends into the sliding groove; along the length direction of the sliding groove, when the limiting part abuts against the end of the sliding groove, the limiting part limits the movement of the linkage member relative to the base.

[0010] The sliding groove is arranged on the linkage member, and when the linkage member moves relative to the base, the position of the limiting part in the sliding groove also changes, and in the present scheme, the sliding groove extends along the length direction of the linkage member.

[0011] During the movement of the linkage member, if the end of the sliding groove abuts against the limiting part, the limiting part limits the continuous movement of the linkage member, thereby limiting the linkage member.

[0012] When the linkage member is arranged between the two adjacent knob assemblies, the limiting part abuts against one end of the sliding groove, which can limit the rotation of one of the two adjacent knob assemblies in the direction of increasing the gear position, and the limiting part abuts against the other end of the sliding groove, which can limit the rotation of the other of the two adjacent knob assemblies in the direction of increasing the gear position.

[0013] In some technical schemes, the limiting part is used for limiting the linkage member, so that the linkage member can reciprocate along the second direction.

[0014] During the movement of the limiting part relative to the base, the limiting part can guide the linkage member, so that the linkage member can only reciprocate along the second direction, thereby ensuring the stability of the limiting part during the movement. Under the guidance of the limiting part, the limiting part is not easy to deviate during the movement, so that the linkage member can stably cooperate with the knob assembly.

[0015] In some technical schemes, the number of limiting parts is at least two, and the at least two limiting parts are distributed at intervals along the movement direction of the linkage member.

[0016] By increasing the number of limiting parts, the at least two limiting parts guide the linkage member at the same time, which is beneficial to improve the guiding accuracy of the linkage member.

[0017] In the case that the number of the limiting portions is at least two, the two limiting portions at the most side can be used to limit the adjacent two knob assemblies respectively, and the stroke of the linkage member can be shortened.

[0018] In some embodiments, the switch assembly further comprises a connecting portion connected to the adjacent two limiting portions.

[0019] The connecting portion is arranged between the adjacent two limiting portions and is used to connect the adjacent two limiting portions. Even if the limiting portion is subjected to the force applied by the linkage member, the position of the limiting portion is not easy to deviate under the connecting action of the connecting portion, so that the limiting portion can stably guide the linkage member.

[0020] In some embodiments, the linkage member comprises a first linkage portion and a second linkage portion. The limiting portion is used to guide the first linkage portion, and the second linkage portion is arranged at both ends of the first linkage portion and is used to cooperate with the knob assembly.

[0021] The linkage member comprises the first linkage portion and the second linkage portion. The second linkage portion is arranged at both ends of the first linkage portion, and one second linkage portion is used to cooperate with one knob assembly, so that one knob assembly is linked with the adjacent knob assembly through the first linkage portion and the second linkage portion.

[0022] In some embodiments, the width of the first linkage portion is greater than the width of the second linkage portion.

[0023] The width of the first linkage portion is greater than the width of the second linkage portion. Therefore, in the length direction of the first linkage portion, a part of the first linkage portion is opposite to the second linkage portion, and the other part of the first linkage portion is distributed in a staggered manner with the second linkage portion, that is, the other part of the first linkage portion is not provided with the second linkage portion corresponding thereto. On this basis, the knob assembly can be arranged opposite to the other part of the first linkage portion, so that the knob assembly is arranged on one side of the length direction of the first linkage portion. In the width direction of the knob assembly, the knob assembly does not protrude out of the first linkage portion, or only a part of the knob assembly protrudes out of the first linkage portion. By arranging the knob assembly in the length direction of the linkage member, the space occupied by the knob assembly in the width direction of the first linkage portion can be reduced, so that the overall width of the switch assembly can be reduced, the volume of the switch assembly can be reduced, and the occupied space of the switch assembly in the cooking device can be reduced, thereby providing convenience for the user to use the cooking device.

[0024] In some embodiments, the base comprises a first shell and a second shell. The first shell is provided with a mounting portion, and the first shell and the second shell are connected through the mounting portion. The side portion of the first linkage portion is provided with a groove, and the groove is used to avoid the mounting portion.

[0025] The first linkage part is provided with a groove, the groove avoids the installation part, avoids the first linkage part and the installation part from interfering, and ensures that the first linkage part can stably move. The first linkage part is provided with the groove only at the position corresponding to the installation part, so that the first linkage part only reduces the width at the position corresponding to the installation part, and the first linkage part still has a large width at other positions, thereby ensuring the structural strength of the first linkage part.

[0026] In some technical solutions, optionally, among the two second linkage parts at the two ends of the first linkage part, one second linkage part is located at a first side of the first linkage part in the width direction, and the other second linkage part is located at a second side of the first linkage part in the width direction.

[0027] The two ends of the first linkage part are respectively provided with second linkage parts, and the two second linkage parts are distributed on different sides of the first linkage part. When one second linkage part rotates clockwise to increase the gear of one knob assembly, the other second linkage part rotates counterclockwise to reduce the gear of one knob assembly. That is, both the two second linkage parts rotate clockwise to increase the gear of the knob assembly, thereby avoiding that the user remembers the direction of adjusting the gear of different knob assemblies.

[0028] In some technical solutions, optionally, the knob assembly comprises: a knob, the knob is provided with a protruding part, and the knob has a free state and a linkage state; a rotating piece, the rotating piece is provided with a guide groove, the protruding part is inserted into the guide groove, and the protruding part can slide in the guide groove; in the free state, the knob can rotate relative to the rotating piece; in the linkage state, the knob can drive the rotating piece to rotate through the protruding part; and the rotating pieces in adjacent two knob assemblies are linked through the linkage piece.

[0029] The user can rotate the knob, change the gear of the knob assembly by rotating the knob, and make the cooking area corresponding to the knob assembly realize the heating function at different powers. The knob is provided with a protruding part, the protruding part is inserted into the guide groove on the rotating piece, when the protruding part and the inner wall in the guide groove link, the knob is in the linkage state, and the knob can drive the rotating piece to rotate. When the protruding part and the inner wall of the guide groove do not link, the knob is in the free state, and the knob will not drive the rotating piece to rotate in the rotating process.

[0030] In the process that the user rotates the knob, when the protruding part and the inner wall of the guide groove link, the knob can drive the rotating piece to rotate, the rotating piece cooperates with the linkage piece, thereby driving the rotating piece of another knob assembly to rotate, and when the rotating piece in the other knob assembly and the knob link, the gears of the adjacent two knob assemblies are linked.

[0031] If the rotating part and the knob in one of the two adjacent knob assemblies are not linked, the two adjacent knob assemblies will not be linked in gear position.

[0032] In some technical solutions, the linkage member comprises a rack, and the rotating part comprises a gear, and the rack is engaged with the gear.

[0033] In the present solution, the rotating part is a gear, and the linkage member is a rack, and when the gear rotates, the gear can drive the rack to move, so that the rack can drive the gear in the other knob assembly to rotate.

[0034] In a second aspect, the utility model provides a kind of cooking equipment, including the switch assembly in the first aspect.

[0035] In some technical solutions, the cooking equipment comprises at least two heating assemblies, and the switch gear position of one knob assembly is associated with the operating power of one heating assembly; the cooking equipment has a maximum heating power W, and the sum of the operating powers of the at least two heating assemblies is less than or equal to the maximum heating power W.

[0036] The cooking equipment usually has a maximum heating power, and if the heating power of the heating assembly corresponding to each heating partition is not limited, the sum of the heating powers of multiple heating assemblies will be greater than the maximum heating power. Or, if the maximum power allowed to operate for each heating assembly is set to be small, the heating efficiency of each heating partition on the cooking accessory will be low, for example, the maximum heating power of the cooking equipment is 2000W, and if the heating partition is two, the maximum power allowed to operate for each heating partition is set to 1000W. The above method limits the heating efficiency, and the waiting time of the user during cooking is long.

[0037] In the present technical solution, when the gear position of one knob assembly increases, the heating power of the corresponding heating assembly will also increase, and if the sum of the powers of the at least two heating assemblies does not reach the maximum heating power, the two adjacent knob assemblies will not be linked in gear position, and the change of the gear position of one knob assembly will not affect the change of the gear position of the other knob assembly. If the sum of the powers of the at least two heating assemblies reaches the maximum heating power, and the gear position of one knob assembly continues to increase, the sum of the powers of the at least two heating assemblies will exceed the maximum heating power, and in order to avoid the above situation, the gear position of the other knob assembly needs to be adjusted downward, so as to reduce the heating power of the other heating assembly.

[0038] The gear linkage is realized through the at least two knob assemblies, so that the gears of part of the knob assemblies can be automatically adjusted when the cooking device is about to overload. In this way, the sum of the powers of the at least two heating assemblies can be prevented from exceeding the maximum heating power, and the user does not need to worry about the problem of overloading operation of the cooking device when using any knob assembly, only needs to adjust the gears of the heating assemblies according to the user's cooking demand, provides convenience for the user's cooking process, and is helpful to improve the user's experience of using the cooking device.

[0039] In some technical solutions, optionally, the knobs in the adjacent two knob assemblies are set as a first knob and a second knob, the at least two heating assemblies include a first heating assembly and a second heating assembly, the gears of the first knob and the second knob are respectively associated with the operating powers of the first heating assembly and the second heating assembly; the operating power of the first heating assembly is P1 when the first knob is at the set gear, the operating power of the first heating assembly is P0 when the first knob is at the maximum gear, and P2=P0-P1; the second knob is in a free state when the operating power of the second heating assembly is less than P2 when the first knob is at the set gear.

[0040] In the at least two knob assemblies, each knob has a maximum gear, and the operating power of the heating assembly corresponding to the maximum gear is P0, which is less than or equal to the maximum heating power W of the cooking device.

[0041] In the adjacent two knob assemblies, the heating power of the first knob corresponding to a gear of the first knob is P1, and the difference between the heating power corresponding to the gear of the first knob at this time and the maximum gear is P2 (P0-P1). When the second knob is rotated, the second knob will not drive the rotating member to rotate in the process of rotation when the heating power corresponding to the gear of the second knob does not reach P2, and the second knob is in a free state at this time.

[0042] In some technical solutions, optionally, P3=W-P0, and the gear of the first knob remains unchanged in the process of adjusting the gear of the second knob when the operating power of the first heating assembly is less than or equal to P3.

[0043] The maximum heating power of the cooking device is W, the heating power corresponding to the maximum gear of the knob is P0, and the difference between W and P0 is P3. If the heating power corresponding to the first knob is less than or equal to P3, the sum of the corresponding heating powers of the first knob and the second knob will not exceed the maximum heating power W even if the second knob operates at the maximum gear in this process, and the adjustment of the gear of the second knob will not link the first knob, so that the first knob is in a free state.

[0044] In some technical solutions, optionally, in a case where the operating power of the first heating assembly is greater than P3, during the increasing of the switch gear of the second knob, the gear of the first knob can change with the second knob.

[0045] If the heating power corresponding to the first knob is greater than P3, during the adjustment of the gear of the second knob, the sum of the heating power corresponding to the first knob and the second knob has the possibility of exceeding the maximum heating power, therefore, when the sum of the power of the first knob and the second knob reaches the maximum heating power, and the gear of the second knob continues to increase, it is necessary to link the first knob to decrease the gear.

DETAILED DESCRIPTION

[0066] In order to enable the above object, features and advantages of the utility model to be more clearly understood, the utility model will be further described below with reference to the drawings and specific embodiments. It should be explained that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0067] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0068] The following description refers to the accompanying drawings. Figures 1 to 16 The switch assembly and the cooking device provided according to some embodiments of the present application are described.

[0069] In combination with Figure 1 and Figure 16 As shown in the figure, in some embodiments of the present application, a switch assembly 100 is provided, comprising a base 150, a knob assembly 110 and a linkage 120, the base 150 is provided with a limiting portion 160, the number of knob assemblies 110 is at least two, and the at least two knob assemblies 110 are arranged on the base 150. The linkage 120 is connected to the adjacent two knob assemblies 110, the adjacent two knob assemblies 110 are linked to each other through the linkage 120, the linkage 120 can move relative to the base 150, and the at least two knob assemblies 110 include a first knob assembly 180, when the first knob assembly 180 rotates towards a first direction (H1) Figure 4 , the arrow in H3 points to, and also can be Figure 4 the opposite direction of the arrow in H3) rotates, the first knob assembly 180 increases the gear, and when the first knob assembly 180 reaches the maximum gear, the limiting portion 160 limits the linkage 120, so that the linkage 120 limits the first knob assembly 180 to rotate towards the first direction.

[0070] The user can rotate the knob assembly 110, change the gear of the knob assembly 110 by rotating the knob assembly 110, so that the corresponding cooking area of the knob assembly 110 realizes the heating function with different power. Different knob assemblies 110 can be linked through the linkage 120, realizing the gear linkage of the adjacent two knob assemblies 110. When the user uses the at least two knob assemblies 110, the gear of one knob assembly 110 is adjusted, and the gears of other knob assemblies 110 can also be adjusted accordingly, and when the user uses multiple cooking areas of the cooking device at the same time, it is not necessary to adjust the gears of multiple knob assemblies 110 in sequence, which provides convenience for the user to use the cooking device.

[0071] One of the at least two knob assemblies 110 is set as a first knob assembly 180, when the first knob assembly 180 is rotated in a first direction, the gear of the first knob assembly 180 is increased, the first direction can be clockwise or counterclockwise. When the first knob assembly 180 is rotated to the maximum gear, the limiting portion 160 on the base 150 limits the linkage 120, the limiting portion 160 limits the movement of the linkage 120 relative to the base 150, because there is a linkage relationship between the first knob assembly 180 and the linkage 120, when the linkage 120 cannot continue to move, the first knob assembly 180 also cannot continue to rotate in the first direction.

[0072] As shown in Figure 1 and Figure 16 , the linkage 120 limits the knob assembly 110, without the need to set a limiting structure between the knob assembly 110 and the base 150, the linkage 120 can realize the linkage function and the limiting function, when the linkage 120 realizes multiple functions at the same time, it is beneficial to simplify the structure of the switch assembly 100, and reduce the processing difficulty of the switch assembly 100.

[0073] As shown in Figure 1 and Figure 16 , in some embodiments, the linkage 120 is provided with a sliding groove 124, and the limiting portion 160 extends into the sliding groove 124. Along the length direction of the sliding groove 124 Figure 1 The arrow at H4 in the figure points to), when the limiting portion 160 abuts against the end of the sliding groove 124, the limiting portion 160 limits the movement of the linkage 120 relative to the base 150.

[0074] The sliding groove 124 is provided on the linkage 120, when the linkage 120 moves relative to the base 150, the position of the limiting portion 160 in the sliding groove 124 will also change, in the present scheme, the sliding groove 124 can extend along the length direction of the linkage 120.

[0075] During the movement of the linkage 120, if the end of the sliding groove 124 abuts against the limiting portion 160, the limiting portion 160 will limit the continuous movement of the linkage 120, thereby limiting the linkage 120.

[0076] When the linkage 120 is provided between the adjacent two knob assemblies 110, the limiting portion 160 abuts against one end of the sliding groove 124, which can limit the rotation of one of the adjacent two knob assemblies 110 in the direction of increasing the gear, and the limiting portion 160 abuts against the other end of the sliding groove, which can limit the rotation of the other of the adjacent two knob assemblies 110 in the direction of increasing the gear.

[0077] As shown inFigure 1 and Figure 16 As shown, in some embodiments, optionally, the limiting portion 160 is used to limit the linkage 120 so that the linkage 120 can move along the second direction ( Figure 1 The arrow at H4 points to the direction of the back-and-forth movement.

[0078] During the movement of the limiting member relative to the base 150, the limiting part 160 guides the linkage member 120, ensuring that the linkage member 120 can only reciprocate along the second direction, thus guaranteeing the stability of the limiting member during movement. Under the guidance of the limiting part 160, the limiting member is less prone to deviation during movement, thereby enabling the linkage member 120 to stably cooperate with the knob assembly 110.

[0079] Combination Figure 1 and Figure 16 As shown, in some embodiments, optionally, the number of limiting portions 160 is at least two, and at least two limiting portions 160 are along the moving direction of the linkage 120 ( Figure 1 The arrow at H4 points to the interval distribution.

[0080] By increasing the number of limiting parts 160, at least two limiting parts 160 can simultaneously guide the linkage 120, which helps to improve the guiding accuracy of the linkage 120.

[0081] When there are at least two limiting parts 160, the two outermost limiting parts 160 can be used to limit the maximum position of two adjacent knob assemblies 110 respectively, which can shorten the travel of the linkage 120.

[0082] Combination Figure 1 and Figure 16 As shown, in some embodiments, the switch assembly 100 may optionally include a connecting portion 170, which is connected to two adjacent limiting portions 160.

[0083] A connecting part 170 is provided between two adjacent limiting parts 160. The connecting part 170 is used to connect the two adjacent limiting parts 160. Under the connection of the connecting part 170, even if the limiting part 160 is subjected to the force applied by the linkage member 120, the position of the limiting part 160 is not easy to shift, thereby ensuring that the limiting part 160 can stably guide the linkage member 120.

[0084] Combination Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the linkage 120 comprises a first linkage portion 121 and a second linkage portion 122, the limiting portion 160 is configured to guide the first linkage portion 121, and the second linkage portion 122 is arranged at both ends of the first linkage portion 121 and configured to cooperate with the knob assembly 110.

[0085] The linkage 120 comprises the first linkage portion 121 and the second linkage portion 122, and the second linkage portion 122 is arranged at both ends of the first linkage portion 121, one second linkage portion 122 is configured to cooperate with one knob assembly 110, so that one knob assembly 110 cooperates with the adjacent knob assembly 110 through the first linkage portion 121 and the second linkage portion 122.

[0086] The width of the first linkage portion 121 is greater than the width of the second linkage portion 122. Figure 3 The arrow at H1 is used to indicate the width direction of the first linkage portion 121 and the second linkage portion 122.

[0087] The width of the first linkage portion 121 is greater than the width of the second linkage portion 122, so that in the length direction of the first linkage portion 121, part of the first linkage portion 121 is opposite to the second linkage portion 122, and the other part of the first linkage portion 121 is distributed in a staggered manner with the second linkage portion 122, that is, the other part of the first linkage portion 121 is not provided with the second linkage portion 122 corresponding thereto, on this basis, the knob assembly 110 can be arranged opposite to the other part of the first linkage portion 121, so that the knob assembly 110 is arranged on one side of the length direction of the first linkage portion 121. In the width direction of the knob assembly 110, the knob assembly 110 does not protrude out of the first linkage portion 121, or only part of the knob assembly 110 protrudes out of the first linkage portion 121. By arranging the knob assembly 110 in the length direction of the linkage 120, the space occupied by the knob assembly 110 in the width direction of the first linkage portion 121 can be reduced, so that the overall width of the switch assembly 100 can be reduced, the volume of the switch assembly 100 can be reduced, and the occupied space of the switch assembly 100 in the cooking equipment can be reduced, thereby providing convenience for the user to use the cooking equipment.

[0088] In the length direction of the first linkage portion 121 in the embodiment, Figure 3 The arrow at H2 is used to indicate the length direction of the first linkage portion 121.

[0089] In some embodiments, optionally, the base comprises a first shell 151 and a second shell 152, the first shell 151 is provided with a mounting portion 153, and the first shell 151 and the second shell 152 are connected through the mounting portion 153. The side of the first linkage portion 121 is provided with a groove 125, and the groove 125 is used for avoiding the mounting portion 153.

[0090] The first linkage portion 121 is provided with a groove 125, the groove 125 avoids the mounting portion 153, avoids the interference between the first linkage portion 121 and the mounting portion 153, and ensures that the first linkage portion 121 can be stably moved. The first linkage portion 121 is only provided with the groove 125 at the position corresponding to the mounting portion 153, so that the first linkage portion 121 only reduces the width at the position corresponding to the mounting portion 153, and the first linkage portion 121 still has a large width at other positions, so as to ensure the structural strength of the first linkage portion 121.

[0091] Exemplarily, the mounting portion 153 can be a plug-in column, so that the first shell 151 and the second shell 152 are connected through a plug-in mode, or the mounting portion 153 can be a mounting hole, and a pin or a screw is used to cooperate with the mounting hole, so as to realize the connection of the first shell 151 and the second shell 152.

[0092] In some embodiments, optionally, among the two second linkage portions 122 at the two ends of the first linkage portion 121, one second linkage portion 122 is located at a first side of the first linkage portion 121 in the width direction, and the other second linkage portion 122 is located at a second side of the first linkage portion 121 in the width direction.

[0093] The two ends of the first linkage portion 121 are respectively provided with the second linkage portion 122, and the two second linkage portions 122 are distributed on different sides of the first linkage portion 121. When one second linkage portion 122 rotates clockwise to increase the gear of one knob assembly 110, the other second linkage portion 122 rotates counterclockwise to reduce the gear of one knob assembly 110, that is, both of the two second linkage portions 122 rotate clockwise to increase the gear of the knob assembly 110, so as to avoid that the user remembers the direction of adjusting the gear of the different knob assemblies 110.

[0094] In combination with FIGS. 1-3, Figure 4 , Figure 5 and Figure 6 In some embodiments, optionally, along the width direction of the first linkage portion 121, the second linkage portion 122 is located at the side of the first linkage portion 121, and the second linkage portions 122 provided at the two ends of the first linkage portion 121 are located at the same side or different sides of the first linkage portion 121.

[0095] The second linkage part 122 is disposed at the end of the first linkage part 121, and the second linkage part 122 is disposed on the side of the first linkage part 121 along the width direction, thereby providing more clearance space for the knob assembly 110.

[0096] In this case, all the knob assemblies 110 can be arranged along the length of the first linkage portion 121, so that the knob assemblies 110 do not protrude from the first linkage portion 121 along the width of the first linkage portion 121. Alternatively, most of the knob assemblies 110 can be arranged along the length of the first linkage portion 121, and a small portion of the knob assemblies 110 can protrude from the first linkage portion 121 along the width of the first linkage portion 121.

[0097] In the width direction of the first linkage part 121, two adjacent knob assemblies 110 can be disposed on the first side of the first linkage part 121, or one of the two adjacent knob assemblies 110 can be disposed on the first side of the first linkage part 121 and the other can be disposed on the second side of the first linkage part 121.

[0098] like Figure 4 As shown, in some embodiments, optionally, two second linkage portions 122 disposed at both ends of the first linkage portion 121 are located on different sides of the first linkage portion 121, and the knob assembly 110 has multiple switch positions along the first direction ( Figure 4 The arrow at H3 could also point to... Figure 4 When any knob assembly 110 is rotated (in the opposite direction of the arrow at H3), the switch position of the knob assembly 110 increases.

[0099] When a user rotates one knob assembly 110, the knob assembly 110 will drive the linkage 120 to move during the rotation, so that the linkage 120 drives the other knob assembly 110 to rotate.

[0100] The second linkage part 122 has a mating surface for engaging with the knob assembly 110. When the two second linkage parts 122 are located on different sides of the first linkage part 121 along its width direction, the mating surfaces of the two second linkage parts 122 face opposite directions. When one knob assembly 110 is rotated clockwise, the other knob assembly 110 will rotate counterclockwise under the influence of the linkage member 120. Furthermore, in this design, when different knob assemblies 110 are rotated in the same direction, the switching position of each knob assembly 110 increases. Therefore, when one of two adjacent knob assemblies 110 rotates clockwise (increasing the position), the other knob assembly 110 rotates counterclockwise (decreasing the position), thus achieving the function of one adjacent knob assembly 110 increasing the position and the other decreasing it, preventing the cooking equipment from operating at excessive power.

[0101] In combination Figure 4 and Figure 5 As shown in FIG. 1, in some embodiments, the two second linkage parts 122 arranged at the two ends of the first linkage part 121 are located at the same side of the first linkage part 121. The knob assembly 110 has multiple switch gears. When the adjacent two knob assemblies 110 are rotated in the first direction, the gear of one knob assembly 110 is increased, and the gear of the other knob assembly 110 is decreased.

[0102] The second linkage part 122 has a matching surface for matching with the knob assembly 110. In the case that the two second linkage parts 122 are arranged at the same side of the first linkage part 121 along the width direction of the first linkage part 121, the matching surfaces of the two second linkage parts 122 are oriented in the same direction. In the case that one knob assembly 110 is rotated in the clockwise direction, the other knob assembly 110 is also rotated in the clockwise direction under the driving of the linkage 120. In this scheme, when the adjacent two knob assemblies 110 are rotated in the same direction, the gear of one knob assembly 110 is increased, and the gear of the other knob assembly 110 is decreased. Therefore, when one of the adjacent two knob assemblies 110 is rotated in the clockwise direction (the gear is increased), the other knob assembly 110 is also rotated in the clockwise direction (the gear is decreased), so as to realize the function that one knob assembly is increased, and the other knob assembly is decreased, and avoid the problem that the running power of the cooking equipment is too high.

[0103] In combination Figure 4 and Figure 6 As shown in FIG. 1, in some embodiments, the two second linkage parts 122 arranged at the two ends of the first linkage part 121 are located at the same side of the first linkage part 121. The knob assembly 110 has multiple switch gears. When the adjacent two knob assemblies 110 are rotated in the first direction, the gear of one knob assembly 110 is increased, and the gear of the other knob assembly 110 is decreased.

[0104] The second linkage part 122 has a matching surface for matching with the knob assembly 110. In the case that the two second linkage parts 122 are arranged at the same side of the first linkage part 121 along the width direction of the first linkage part 121, the matching surfaces of the two second linkage parts 122 are oriented in the same direction.

[0105] In the case where the transmission member 130 is not arranged, the two knob assemblies 110 rotate in the same direction under the driving of the linkage member 120. In the present scheme, one knob assembly 110 of the two adjacent knob assemblies 110 is matched with the linkage member 120 through the transmission member 130. In the case where one knob assembly 110 rotates in the clockwise direction, the linkage member 120 moves relative to the knob assembly 110, and the knob assembly 110 drives the other knob assembly 110 to rotate through the transmission member 130. The transmission member 130 can change the transmission direction, so that the two adjacent knob assemblies 110 rotate in opposite directions. In the present scheme, when the different knob assemblies 110 are rotated in the same direction, the switch gear position of any knob assembly 110 is increased. Therefore, when one knob assembly 110 of the two adjacent knob assemblies 110 rotates in the clockwise direction (the gear position is increased), the other knob assembly 110 also rotates in the clockwise direction (the gear position is decreased), so as to realize the function that one knob assembly 110 increases the gear position and the other knob assembly 110 decreases the gear position, and avoid the problem that the operating power of the cooking equipment is too high.

[0106] As shown in Figure 3 In some embodiments, the switch assembly 100 optionally further comprises a reinforcing portion 140, which is arranged on the second linkage portion 122 and located on the side of the second linkage portion 122 away from the knob assembly 110.

[0107] Since the width of the second linkage portion 122 is smaller than the width of the first linkage portion 121, the structural strength of the second linkage portion 122 is smaller than the structural strength of the first linkage portion 121. In the present scheme, the reinforcing portion 140 is arranged on the second linkage portion 122, and the reinforcing portion 140 is used to improve the structural strength of the second linkage portion 122, so as to avoid that the second linkage portion 122 is forced to move away from the knob assembly 110, and ensure that the second linkage portion 122 can stably cooperate with the knob assembly 110. The reinforcing portion 140 is arranged on the side of the second linkage portion 122 away from the knob assembly 110, so as to avoid that the reinforcing portion 140 interferes with the cooperation position of the second linkage portion 122 and the knob assembly 110.

[0108] The reinforcing portion 140 can be the same material as the linkage member 120, and the reinforcing portion 140 is directly and integrally formed on the second linkage portion 122, so as to increase the local thickness of the second linkage portion 122.

[0109] As shown in Figure 3 In some embodiments, the first linkage portion 121 and the second linkage portion 122 are arranged at an angle α in the length direction, and α>90°.

[0110] The first linkage part 121 has an included angle between the length direction side and the second linkage part 122, and the included angle is obtuse. In the case that the second linkage part 122 is forced, the obtuse angle structure makes the force of the first linkage part 121 and the second linkage part 122 at the connection position dispersed to a wider area, reduces the risk of bending of the second linkage part 122 relative to the first linkage part 121, and ensures that the second linkage part 122 can stably cooperate with the knob assembly 110.

[0111] Exemplarily, a is 100°, 110° or 120°.

[0112] In some embodiments, optionally, the knob assembly 110 comprises a knob 111 and a rotating piece 113, the knob 111 is provided with a protruding part 112, the knob 111 has a free state and a linkage state, the rotating piece 113 is provided with a guide groove 114, the protruding part 112 is inserted into the guide groove 114, the protruding part 112 can slide in the guide groove 114, in the free state, the knob 111 can rotate relative to the rotating piece 113, in the linkage state, the knob 111 can drive the rotating piece 113 to rotate through the protruding part 112, and the rotating pieces 113 in adjacent two knob assemblies 110 are linked through the linkage piece 120.

[0113] The user can rotate the knob 111, change the gear of the knob assembly 110 by rotating the knob 111, and make the corresponding cooking area of the knob assembly 110 realize the heating function with different power. The knob 111 is provided with a protruding part 112, the protruding part 112 is inserted into the guide groove 114 on the rotating piece 113, when the protruding part 112 and the inner wall of the guide groove 114 are linked, the knob 111 is in the linkage state, and the knob 111 can drive the rotating piece 113 to rotate. When the protruding part 112 and the inner wall of the guide groove 114 are not linked, the knob 111 is in the free state, and the knob 111 will not drive the rotating piece 113 to rotate in the rotating process.

[0114] In the process that the user rotates the knob 111, when the protruding part 112 and the inner wall of the guide groove 114 are linked, the knob 111 can drive the rotating piece 113 to rotate, the rotating piece 113 cooperates with the linkage piece 120, thereby driving the rotating piece 113 of another knob assembly 110 to rotate, and when the rotating piece 113 and the knob 111 in the other knob assembly 110 are linked, the gear linkage of the adjacent two knob assemblies 110 is realized.

[0115] If the rotating member 113 and the knob 111 in one of the two adjacent knob assemblies 110 do not produce linkage, the two adjacent knob assemblies 110 will not produce gear linkage. Therefore, the matching design of the protruding part 112 and the guide groove 114 makes the switch assembly 100 have different functions of gear linkage and gear free adjustment, and improves the functionality of the switch assembly 100.

[0116] In combination Figure 2 , Figure 7 , Figure 11 and Figure 12 , in some embodiments, the guide groove 114 optionally includes a first groove end 1141 and a second groove end 1142. In the linkage state, the protruding part 112 contacts the first groove end 1141 or the second groove end 1142. In the free state, the protruding part 112 is separated from the first groove end 1141 and the second groove end 1142.

[0117] During the rotation of the knob 111, the protruding part 112 can slide in the guide groove 114. When the protruding part 112 does not contact the two ends of the guide groove 114, the protruding part 112 will not push the rotating member 113, so the knob 111 can rotate relative to the rotating member 113. At this time, the rotating member 113 will not rotate with the knob 111.

[0118] When the protruding part 112 contacts the end of the guide groove 114, if the knob 111 continues to rotate, the protruding part 112 will push the end of the guide groove 114, so that the rotating member 113 can rotate with the knob 111. The rotating member 113 in one knob assembly 110 can link the rotating member 113 in the other knob assembly 110. When the protruding part 112 in the other knob assembly 110 contacts the end of the guide groove 114, the gears of the two knob assemblies 110 will be linked.

[0119] Of course, in other embodiments, a protruding structure can be arranged in the guide groove 114, which is used to cooperate with the protruding part 112, that is, the protruding part 112 does not need to contact the groove end of the guide groove 114. When the protruding part 112 contacts the protruding structure, the protruding part 112 can push the rotating member 113.

[0120] In some embodiments, the central angle between the first groove end 1141 and the second groove end 1142 is α1, and the central angle of the knob 111 rotating from the minimum gear to the maximum gear is α2, and α1>α2.

[0121] The corresponding central angle of the two ends of the guide groove 114 is α1, and the circle formed by the maximum gear difference of the knob 111 is α2, and α1>α2.

[0122] For the cooking device with at least two knob assemblies 110, generally with at least two heating assemblies 200, one knob assembly 110 is used to control one heating assembly 200. In order to avoid the sum of heating powers of the at least two heating assemblies 200 exceeding the maximum heating power of the cooking device, it is required to set the at least two knob assemblies 110 to be linked. When rotating one knob 111, if the sum of operating powers of the at least two heating assemblies 200 is about to exceed the maximum heating power, it is required to reduce the gear of the other knob 111, so as to reduce the heating power of the other heating assembly 200.

[0123] During the process of reducing the gear of the knob 111 by the user, the sum of heating powers of the at least two heating assemblies 200 will not exceed the maximum heating power, thus, during the reduction of the gear of one knob 111, it is not required to realize the linkage with the other knob 111, and in the present scheme, it is limited that α1>α2, during the reduction of the gear of the knob 111, the knob 111 rotates relative to the rotating member 113, even if the knob 111 rotates from the maximum gear to the minimum gear, the knob 111 will not push the rotating member 113.

[0124] In other embodiments, α1=α2 can also be set.

[0125] In combination with Figure 2 , Figure 7 , Figure 11 and Figure 12 , in some embodiments, the rotating member 113 is provided with an axle hole 1131, the axle hole 1131 is communicated with the guide groove 114, and the knob 111 is inserted into the axle hole 1131.

[0126] The rotating member 113 is provided with the axle hole 1131, the knob 111 can be inserted into the axle hole 1131, the convex part 112 is arranged on the knob 111, thus, the axle hole 1131 is communicated with the guide groove 114, the convex part 112 can extend out of the axle hole 1131, so that the convex part 112 cooperates with the guide groove 114.

[0127] In combination with Figure 2 , Figure 7 , Figure 11 , Figure 12 and Figure 13As shown in the figure, in some embodiments, the knob 111 comprises: a gear switch 1113, a rotating shaft 1114 and a knob body 1117, the gear switch 1113 has a plurality of switch gears, the rotating shaft 1114 is connected with the gear switch 1113, and the rotating shaft 1114 is used to drive the gear switch 1113 to adjust the switch gears. In the radial section of the rotating shaft 1114, the section of the rotating shaft 1114 comprises an arc segment 1115 and a driving segment 1116. The knob body 1117 is inserted with the rotating shaft 1114, the arc segment 1115 is used to make the rotating shaft 1114 rotate concentrically with the knob body 1117, and the driving segment 1116 is used to make the rotating shaft 1114 rotate synchronously with the knob body 1117.

[0128] The user can rotate the knob body 1117, the knob body 1117 is inserted with the rotating shaft 1114, and the rotating shaft 1114 can rotate synchronously with the knob body 1117, and the rotating shaft 1114 can drive the gear switch 1113 to adjust the gears when rotating.

[0129] In the radial section of the rotating shaft 1114, at least two parts of the section have different profiles, at least one part of the section has an arc shape, the arc segment 1115 is arranged concentrically with the knob body 1117, so that the rotating shaft 1114 can rotate concentrically with the knob body 1117. Another part of the section is the driving segment 1116, which can be a straight line structure. The straight line structure limits the knob body 1117 in the circumferential direction, so that the rotating shaft 1114 and the knob body 1117 can rotate synchronously. Of course, the driving segment 1116 can also have other shapes, for example, the driving segment 1116 can have an arc structure, but the curvature of the driving segment 1116 is smaller than that of the arc segment 1115. Alternatively, the driving segment 1116 can also have a wave shape or other structures.

[0130] In this embodiment, the D-shaped structure is adopted between the rotating shaft 1114 and the knob body 1117 to limit the cooperation between the rotating shaft 1114 and the knob body 1117.

[0131] The gear switch 1113 in this embodiment has the same working principle as the gear switch 1113 in the related art, and will not be described here.

[0132] In combination Figure 12 And Figure 13 As shown in the figure, in some embodiments, the gear switch 1113 is provided with an output shaft 1118, the rotating shaft 1114 is provided with an insertion hole 1119, the output shaft 1118 is inserted into the insertion hole 1119, and the insertion hole 1119 is provided with a reinforcing rib 1120 extending along the axial direction of the rotating shaft 1114.

[0133] The rotating shaft 1114 is provided with a plug hole 1119 extending along the axial direction of the rotating shaft 1114, and the gear switch 1113 is provided with an output shaft 1118 which is plugged into the plug hole 1119, and the rotating shaft 1114 drives the output shaft 1118 to rotate synchronously, thereby adjusting the gear of the gear switch 1113. Since the rotating shaft 1114 is provided with a hole, the structural strength of the rotating shaft 1114 is reduced, and in the present scheme, a reinforcing rib 1120 is arranged in the plug hole, which is used to enhance the structural strength of the rotating shaft 1114, avoid deformation of the rotating shaft 1114, and ensure that the rotating shaft 1114 stably cooperates with the knob body 1117 and the output shaft 1118.

[0134] In other embodiments, the reinforcing rib 1120 can also be distributed in other ways, for example, in a cross-shaped manner on the inner wall of the plug hole 1119.

[0135] As shown in Figure 7 some embodiments, along the circumferential direction of the rotating shaft 1114, the first side (the position indicated by a in Figure 7 ) of the protruding part 112 is used to push the rotating part 113, and the second side (the position indicated by b in Figure 7 ) of the protruding part 112 has an included angle with the first side of the protruding part 112.

[0136] The first side of the protruding part 112 is used to push the rotating part 113, that is, the first side of the protruding part 112 can abut against one end of the guide groove 114, thereby pushing the inner wall of the guide groove 114. Exemplarily, the first side of the protruding part 112 extends along the radial direction of the rotating shaft 1114, and since the first side and the second side of the protruding part 112 have an included angle, the second side of the protruding part 112 does not extend along the radial direction of the rotating shaft 1114. In this case, the head of the protruding part 112 is narrower, and the bottom of the protruding part 112 is wider, which is beneficial to increase the contact area of the protruding part 112 and the rotating shaft 1114, thereby improving the connection stability of the protruding part 112 and the rotating shaft 1114.

[0137] In some embodiments, the linkage 120 includes a gear rack 123, and the rotating part 113 includes a gear wheel 115, and the gear rack 123 is engaged with the gear wheel 115.

[0138] In the present scheme, the rotating part 113 is a gear wheel 115, and the linkage 120 is a gear rack 123, and when the gear wheel 115 rotates, the gear wheel 115 can drive the gear rack 123 to move, so that the gear rack 123 can drive the gear wheel 115 in another knob assembly 110 to rotate.

[0139] Of course, in other embodiments, the linkage 120 can also be a chain, and the rotating part 113 can be a sprocket.

[0140] In some embodiments of the utility model, a cooking equipment is provided, which comprises the switch assembly 100 in any of the above embodiments and can achieve the same technical effects, and details are not repeated here.

[0141] As shown in the figure, in some embodiments, the cooking equipment optionally comprises at least two heating assemblies 200 (in other embodiments, the structure of the heating assembly 200 is not limited to that shown in the figure), and the switch gear of one knob assembly 110 is associated with the operating power of one heating assembly 200. The cooking equipment has a maximum heating power W, and the sum of the operating powers of the at least two heating assemblies 200 is less than or equal to the maximum heating power W. Figure 15 Figure 15 The cooking equipment usually has a maximum heating power, in the case of multiple heating partitions provided on the cooking equipment, if the heating power of the heating assembly 200 corresponding to each heating partition is not limited, the sum of the heating powers of multiple heating assemblies 200 will be greater than the maximum heating power. Or, if the maximum power allowed to operate of each heating assembly 200 is set to be small, it will lead to low heating efficiency of each heating partition to the cooking accessory, for example, the maximum heating power of the cooking equipment is 2000W, in the case of two heating partitions, the maximum power allowed to operate of each heating partition is set to be 1000W, the above way limits the heating efficiency, and the waiting time of the user in the cooking process is long.

[0142] In the embodiment, when the gear of one of the knob assemblies 110 increases, the heating power of the corresponding heating assembly 200 will also increase, if the sum of the powers of the at least two heating assemblies 200 does not reach the maximum heating power, then the gears of the adjacent two knob assemblies 110 will not be linked, and the gear change of one knob assembly 110 will not affect the gear change of the other knob assembly 110. If the sum of the powers of the at least two heating assemblies 200 reaches the maximum heating power, and the gear of one of the knob assemblies 110 continues to increase, the sum of the powers of the at least two heating assemblies 200 will exceed the maximum heating power, in order to avoid the above situation, the gears of the other knob assemblies 110 need to be adjusted downward, so as to reduce the heating power of the other heating assemblies 200.

[0143] In the embodiment, when the gear of one of the knob assemblies 110 increases, the heating power of the corresponding heating assembly 200 will also increase, if the sum of the powers of the at least two heating assemblies 200 does not reach the maximum heating power, then the gears of the adjacent two knob assemblies 110 will not be linked, and the gear change of one knob assembly 110 will not affect the gear change of the other knob assembly 110. If the sum of the powers of the at least two heating assemblies 200 reaches the maximum heating power, and the gear of one of the knob assemblies 110 continues to increase, the sum of the powers of the at least two heating assemblies 200 will exceed the maximum heating power, in order to avoid the above situation, the gears of the other knob assemblies 110 need to be adjusted downward, so as to reduce the heating power of the other heating assemblies 200.

[0144] ​By using at least two knob components 110 to achieve gear linkage, the gear settings of some knob components 110 can be automatically adjusted when the cooking equipment is about to be overloaded. This method prevents the combined power of at least two heating components 200 from exceeding the maximum heating power. Users do not need to worry about overloading the cooking equipment when using any knob component 110; they only need to adjust the gear settings of the heating components 200 according to their cooking needs, providing convenience for the user's cooking process and improving the user experience of the cooking equipment.

[0145] The heating element 200 can be a heating tube or a heating wire.

[0146] In related technologies, for cooking devices with separate cooking zones, the maximum power of the left and right cooking zones is limited to 1000W (a total power exceeding 2000W will damage the circuit). This embodiment uses a linkage mechanical knob 111 structure, breaking the traditional limitation that the maximum power of the left and right knobs is only 1000W.

[0147] Combination Figure 14 and Figure 15 As shown, in some embodiments, optionally, the knobs 111 in two adjacent knob assemblies 110 are designated as a first knob 1111 and a second knob 1112, respectively. At least two heating assemblies 200 include a first heating assembly 210 and a second heating assembly 220. The settings of the first knob 1111 and the second knob 1112 are respectively associated with the operating power of the first heating assembly 210 and the second heating assembly 220. When the first knob 1111 is in its set setting, the operating power of the first heating assembly 210 is P1. When the first knob 1111 is in its maximum setting, the operating power of the first heating assembly 210 is P0, and P2 = P0 - P1. When the first knob 1111 is in its set setting, and the operating power of the second heating assembly 220 is less than P2, the second knob 1112 is in a free state.

[0148] In at least two knob assemblies 110, each knob 111 has a maximum setting, and the operating power of the heating assembly 200 corresponding to the maximum setting is P0, which is less than or equal to the maximum heating power W of the cooking device.

[0149] In two adjacent knob assemblies 110, when the first knob 1111 is in a certain position, the heating power corresponding to the first knob 1111 is P1. The difference in heating power between the first knob 1111 at this position and the maximum position is P2 (P0-P1). When the second knob 1112 is rotated, if the heating power corresponding to the position of the second knob 1112 does not reach P2, the second knob 1112 will not drive the rotating component 113 to rotate during rotation, and the second knob 1112 is in a free state.

[0150] The control process of the cooking device is as follows: after the first knob 1111 is increased, it is judged whether the sum of the powers of the first heating assembly 210 and the second heating assembly 220 will exceed 2000W, if it exceeds 2000W, the second knob 1112 is decreased, if it will not exceed 2000W, it is normally operated.

[0151] Exemplarily, the knob 111 in the embodiment has four gears, the knob 111 increases or decreases one gear every 45° of rotation, and the four gears are 0W (the state shown in the left), 500W (the state shown in the middle), 1000W (the state shown in the right) and 1500W (the state shown in the right) respectively. Figure 7 Of course, in other embodiments, the gears of the knob 111 are not limited to four, and the states of the gears are not limited to the states shown in the left, the middle and the right.

[0152] Operation explanation:

[0153] Firstly, the starting gears of the first knob 1111 and the second knob 1112 are 0 gears.

[0154] Secondly, if the sum of the powers of the at least two heating assemblies 200 is less than or equal to 1500W, one of the knobs 111 is increased or decreased by one gear, and the other knob 111 will not rotate.

[0155] Thirdly, the sum of the powers of the at least two heating assemblies 200 is equal to 2000W, and the two knob assemblies 110 and the linkage 120 are in a critical state.

[0156] Fourthly, the sum of the powers of the at least two heating assemblies 200 is equal to 2000W, one of the knobs 111 is increased, and the linkage 120 drives the other knob 111 to decrease.

[0157] The left and right knobs 111 are linked, when the operating side is increased (the total power is about to exceed 2000W), the passive side will be decreased (to ensure that the adjusted power is less than or equal to 2000W). In this case, more options are given to the mechanical gear, the total power does not exceed 2000W, and the safety of the household appliance is ensured.

[0158] The gear space structure (the operating side is decreased, and the gear of the passive side is unchanged) makes there be a gear space in the linkage of the knob 111, when the operating side is decreased, the passive side is not disturbed, which is beneficial to optimize the user experience and ensure that the total power is less than or equal to 2000W when the gears are increased or decreased at will.

[0159] ​​​​In some embodiments, optionally, P3=W-P0 is set, and in the case that the operating power of the first heating assembly 210 is less than or equal to P3, the gear of the first knob 1111 remains unchanged during the gear adjustment of the second knob 1112.

[0160] The maximum heating power of the cooking device is W, and the heating power corresponding to the maximum gear of the knob 111 is P0, and the difference between W and P0 is P3. If the heating power corresponding to the first knob 1111 is less than or equal to P3, even if the second knob 1112 is operated at the maximum gear, the sum of the corresponding heating powers of the first knob 1111 and the second knob 1112 will not exceed the maximum heating power W, and in this process, the adjustment of the gear of the second knob 1112 will not link the first knob 1111, so that the first knob 1111 is in a free state.

[0161] In some embodiments, optionally, in the case that the operating power of the first heating assembly 210 is greater than P3, the gear of the first knob 1111 can change with the second knob 1112 during the increase of the switching gear of the second knob 1112.

[0162] If the heating power corresponding to the first knob 1111 is greater than P3, in the process of adjusting the gear of the second knob 1112, the sum of the corresponding heating powers of the first knob 1111 and the second knob 1112 may exceed the maximum heating power, so when the sum of the powers of the first knob 1111 and the second knob 1112 reaches the maximum heating power, and the gear of the second knob 1112 continues to increase, it is necessary to link the first knob 1111 to reduce the gear.
