Therefore, the features defined as "first", "second" can be explicitly or implicitly included at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the protection scope claimed by the present application.

[0054] The first aspect of the present application discloses a gas control device, which combines Figures 1 to 6 As shown in the drawings, in some embodiments, the gas control device comprises an air inlet seat 1000, a control valve 2000, a first gas valve 3000 and a second gas valve 4000, the air inlet seat 1000 is provided with an air inlet channel 1100 and an air outlet channel 1200, the air outlet channel 1200 is provided with an air inlet port 1211, the air inlet port 1211 is in communication with the air inlet channel 1100, that is, the air outlet channel 1200 is in communication with the air inlet channel 1100 through the air inlet port 1211, the control valve 2000 is connected with the air inlet seat 1000, the control valve 2000 comprises a valve core 2200, the valve core 2200 is movably arranged so as to abut against or be separated from the air inlet port 1211, when the valve core 2200 abuts against the air inlet port 1211, the valve core 2200 blocks part of the air inlet port 1211, the first gas valve 3000 is connected with the air inlet seat 1000, and the first gas valve 3000 is in communication with a first outlet 1221 of the air outlet channel 1200, the second gas valve 4000 is connected with the air inlet seat 1000, and the second gas valve 4000 is in communication with a second outlet 1231 of the air outlet channel 1200.

[0055] The cooperation of the air inlet seat 1000 and the control valve 2000 can realize the switching of the normal gas supply and the wok frying gas supply of the first gas valve 3000 and the second gas valve 4000, without the need of structural improvement of the first gas valve 3000 and the second gas valve 4000, the first gas valve 3000 and the second gas valve 4000 can adopt the mature products on the market at present, which has strong compatibility and is conducive to reducing the structural complexity and cost. Since the overall gas supply of the first gas valve 3000 and the second gas valve 4000 can be controlled, when the wok frying gas supply is performed on the first gas valve 3000 and the second gas valve 4000, the outer ring and the inner ring of the corresponding burner can be simultaneously in the wok frying state, and the heating of the cooker is more uniform.

[0056] Specifically, the gas inlet seat 1000 needs to be connected with a gas source, which can be a filling liquefied gas or a pipeline natural gas. The gas source is connected to the gas inlet channel 1100 of the gas inlet seat 1000, and the gas provided by the gas source enters the interior of the gas inlet seat 1000 through the gas inlet channel 1100, and then can enter the gas outlet channel 1200 through the gas inlet port 1211 and flow along the gas outlet channel 1200 to be discharged. The gas inlet seat 1000 can be an integrally formed structure or a split component connected together. Since the gas inlet seat 1000 is provided with several channels (the gas inlet channel 1100 and the gas outlet channel 1200), the gas inlet seat 1000 is designed as an integrally formed structure, which is more conducive to preventing gas leakage and reducing the number of sealing points.

[0057] The first gas valve 3000 is connected with the gas inlet seat 1000 and communicates with the first outlet 1221 of the gas outlet channel 1200. The gas discharged through the gas outlet channel 1200 can flow through the first gas valve 3000 through the first outlet 1221, and the first gas valve 3000 can adjust the flow of the gas flowing therethrough. The second gas valve 4000 is connected with the gas inlet seat 1000 and communicates with the second outlet 1231 of the gas outlet channel 1200. The gas discharged through the gas outlet channel 1200 can also flow through the second gas valve 4000 through the second outlet 1231, and the second gas valve 4000 can adjust the flow of the gas flowing therethrough. The types of the first gas valve 3000 and the second gas valve 4000 are various, such as plug valves, ball valves, butterfly valves, etc., which can be selected according to actual conditions. Commonly used for gas stoves can adopt plug valves. The first gas valve 3000 and the second gas valve 4000 are split components connected and fixed with the gas inlet seat 1000 by connecting means, such as screw connection, welding, etc.

[0058] In the embodiment, the control valve 2000 is provided, and the gas discharged through the outlet passage 1200 needs to be controlled by the control valve 2000 to realize the switching of the normal gas supply and the stir-frying gas supply of the first gas valve 3000 and the second gas valve 4000. The control valve 2000 comprises a valve core 2200, which is a movable component. The movement of the valve core 2200 has two states. The first state is that the valve core 2200 abuts against the inlet 1211, and the second state is that the valve core 2200 is separated from the inlet 1211. When the valve core 2200 abuts against the inlet 1211, the valve core 2200 blocks part of the inlet 1211. When the valve core 2200 is separated from the inlet 1211, the inlet 1211 is completely opened (relative to the state that the valve core 2200 abuts against the inlet 1211). That is, when the valve core 2200 abuts against the inlet 1211, the opening degree of the inlet 1211 is relatively small, so that the gas flow rate / pressure entering the outlet passage 1200 is small. When the valve core 2200 is separated from the inlet 1211, the opening degree of the inlet 1211 is relatively large, so that the gas flow rate / pressure entering the outlet passage 1200 is large. In this way, when the valve core 2200 abuts against the inlet 1211, the normal gas supply of the first gas valve 3000 and the second gas valve 4000 can be realized. When the valve core 2200 is separated from the inlet 1211, the stir-frying gas supply of the first gas valve 3000 and the second gas valve 4000 can be realized (the firepower of the stir-frying gas supply is larger than that of the normal gas supply).

[0059] The gas control device is further described by taking a gas stove as an example. The gas stove comprises the gas control device, a first burner and a second burner. The inlet passage 1100 of the gas inlet seat 1000 is connected to a gas source. The gas in the gas source enters the inside of the gas inlet seat 1000 through the inlet passage 1100, and then enters the outlet passage 1200 through the inlet 1211 and flows along the outlet passage 1200 to be discharged. The gas flowing along the outlet passage 1200 can flow out through the first outlet 1221 to flow through the first gas valve 3000, and the gas flow rate flowing to the first burner is controlled by the first gas valve 3000. The gas flowing along the outlet passage 1200 can also flow out through the second outlet 1231 to flow through the second gas valve 4000, and the gas flow rate flowing to the second burner is controlled by the second gas valve 4000. The flow form of the gas is as follows:

[0063] The fourth kind, only through the second burner heating cookware and valve core 2200 away from the air inlet 1211, open the second gas valve 4000, gas from the air inlet channel 1100 into the air inlet seat 1000 inside and through the air inlet 1211 into the air outlet channel 1200, gas along the air outlet channel 1200 and from the second outlet 1231 flow out to flow through the second gas valve 4000, so as to realize the second gas valve 4000 of the explosive stir-frying gas supply, the second gas valve 4000 can adjust the gas flow to the second burner, at this time the gas stove can realize the heating of the second burner in the explosive stir-frying mode.

[0064] Fifth, the first and second burners heat the cookware, the valve core 2200 abuts against the air inlet 1211, the first and second gas valves 3000 and 4000 are opened, the gas enters the inside of the air inlet seat 1000 from the air inlet channel 1100 and flows into the air outlet channel 1200 through the air inlet 1211, the gas flows along the air outlet channel 1200 and flows out from the first outlet 1221 to pass through the first gas valve 3000, and flows out from the second outlet 1231 to pass through the second gas valve 4000, thus realizing the regular gas supply to the first and second gas valves 3000 and 4000, the first gas valve 3000 can adjust the gas flow to the first burner, and the second gas valve 4000 can adjust the gas flow to the second burner, at this time, the gas stove can realize regular heating through the first and second burners.

[0065] Sixth, the first and second burners heat the cookware, the valve core 2200 is separated from the air inlet 1211, the first and second gas valves 4000 are opened, the gas enters the inside of the air inlet seat 1000 from the air inlet channel 1100 and flows into the air outlet channel 1200 through the air inlet 1211, the gas flows along the air outlet channel 1200 and flows out from the first outlet 1221 to pass through the first gas valve 3000, and flows out from the second outlet 1231 to pass through the second gas valve 4000, thus realizing the wok frying gas supply to the first and second gas valves 3000 and 4000, the first gas valve 3000 can adjust the gas flow to the first burner, and the second gas valve 4000 can adjust the gas flow to the second burner, at this time, the gas stove can realize wok frying heating through the first and second burners.

[0066] Generally, the first burner is provided with outer and inner ring fire holes, the second burner is also provided with outer and inner ring fire holes, the first and second gas valves 3000 and 4000 are both provided with outer ring channels 3200 / 4200 and inner ring channels 3100 / 4100, the outer ring channels 3200 / 4200 control the gas supply of the outer ring fire holes, and the inner ring channels 3100 / 4100 control the gas supply of the inner ring fire holes, whether the valve core 2200 abuts against the air inlet 1211 or is separated from the air inlet 1211, the whole first and second gas valves 3000 and 4000 are adjusted for gas supply, that is, when the first gas valve 3000 is regularly supplied with gas, the outer and inner ring channels 3200 and 3100 of the first gas valve 3000 can be regularly supplied with gas, and when the first gas valve 3000 is wok frying supplied with gas, the outer and inner ring channels 3200 and 3100 of the first gas valve 3000 can be wok frying supplied with gas, so that the outer and inner ring fire holes of the first burner can be simultaneously wok frying heated or simultaneously regularly heated, the cookware is more uniformly heated, and the same is true for the second gas valve 4000, which will not be repeated.

[0067] Optionally, the air inlet channel 1100 is located between the first gas valve 3000 and the second gas valve 4000, which is beneficial to rationalize the use of space and facilitate the air inlet connection of the air inlet channel 1100.

[0068] In combination Figures 7 to 14 As shown, in some embodiments, the valve core 2200 is adapted to abut the periphery of the air inlet 1211, and the valve core 2200 is provided with a communication channel 2210 adapted to communicate the air inlet channel 1100 and the remaining part of the air inlet 1211, respectively, when the valve core 2200 abuts the periphery of the air inlet 1211. By abutting the periphery of the air inlet 1211, the valve core 2200 is subjected to more uniform force (reaction force exerted by the periphery of the air inlet 1211), which helps to improve the effect of the valve core 2200 on the partial plugging of the air inlet 1211, avoid leakage, and ensure regular gas supply. Since the valve core 2200 is movable, the more uniform force on the valve core 2200 is more conducive to prolonging the service life of the control valve 2000.

[0069] When the valve core 2200 abuts the periphery of the air inlet 1211, one end of the communication channel 2210 communicates with the remaining part of the air inlet 1211, and the other end communicates with the air inlet channel 1100 (the cross-sectional size of the communication channel 2210 can be set according to the heat required for regular heating). In combination Figures 7 to 14 As shown, one end of the communication channel 2210 is located at a middle position of the valve core 2200, so that when the valve core 2200 abuts the periphery of the air inlet 1211, the communication channel 2210 and the remaining part of the air inlet 1211 are communicated, that is, the communication channel 2210 is communicated with the air outlet channel 1200. Since the other end of the communication channel 2210 is communicated with the air inlet channel 1100, the communication between the air inlet channel 1100 and the air outlet channel 1200 is realized. When the valve core 2200 abuts the periphery of the air inlet 1211, the gas enters the inside of the air inlet seat 1000 from the air inlet channel 1100 and flows through the communication channel 2210, the remaining part of the air inlet 1211 in turn, and then flows into the air outlet channel 1200.

[0070] Optionally, the valve core 2200 can be provided with a sealing gasket 2220, and the valve core 2200 abuts the periphery of the air inlet 1211 through the sealing gasket 2220. The sealing gasket 2220 is adapted to elastically deform, so that a better sealing effect can be achieved. Under the premise that the valve core 2200 has the sealing gasket 2220, the sealing gasket 2220 has a ring structure and surrounds one end of the communication channel 2210.

[0071] In combination Figures 7 to 14As shown, in some embodiments, the communication passage 2210 includes a first communication passage 2211 and a second communication passage 2212, the first communication passage 2211 and the second communication passage 2212 intersect to communicate (intersect means that the two are not in a straight line, the same below), the communication passage 2210 is adapted to communicate through the first communication passage 2211 and the air inlet passage 1100, and the communication passage 2210 is adapted to communicate through the second communication passage 2212 and the remaining part of the air inlet 1211. Through the intersecting communication of the first communication passage 2211 and the second communication passage 2212, it is more convenient to arrange and cooperate with each structure. The so-called intersecting communication means that the two are not straight but form an included angle.

[0072] For example, the valve core 2200 is designed to be reciprocally movable along its axial direction, the air inlet 1211 is located in the axial direction of the valve core 2200, the valve core 2200 moves towards the air inlet 1211 so as to abut against the air inlet 1211, and moves away from the air inlet 1211 so as to be separated from the air inlet 1211. On this basis, by providing the first communication passage 2211 and the second communication passage 2212, the first communication passage 2211 realizes communication with the air inlet passage 1100, and the second communication passage 2212 realizes communication with the remaining part of the air inlet 1211. The gas flows through the first communication passage 2211 and the second communication passage 2212 in turn to enter the air outlet passage 1200 through the air inlet 1211. In this way, the valve core 2200 can realize plugging of the air inlet 1211, and the air inlet passage 1100 and the air outlet passage 1200 can realize communication, and in particular, the first communication passage 2211 can be designed to extend along the radial direction of the valve core 2200, and the second communication passage 2212 can be designed to extend along the axial direction of the valve core 2200, thereby reducing the machining difficulty of the first communication passage 2211 and the second communication passage 2212.

[0074] It can be understood that the communication between the air inlet passage 1100 and the containing cavity 1300 means that the gas enters the containing cavity 1300 from the air inlet passage 1100 (the gas flowing along the air inlet passage 1100 flows into the containing cavity 1300), and the communication between the air inlet 1211 and the containing cavity 1300 means that the gas enters the air outlet passage 1200 from the containing cavity 1300 (the gas flowing into the containing cavity 1300 continues to flow into the air outlet passage 1200).

[0075] The accommodation cavity 1300 is arranged to facilitate the movement of the valve core 2200 and the communication between the passages (the gas inlet passage 1100 and the gas outlet passage 1200). For example, the accommodation cavity 1300 has an opening 1310, the control valve 2000 is arranged to the gas inlet seat 1000 with the opening 1310, the valve core 2200 is inserted into the accommodation cavity 1300 through the opening 1310, and the valve core 2200 can move in the accommodation cavity 1300.

At this time, the gas stove can realize explosive frying mode heating through the first burner.

[0079] Thirdly, only the second burner heats the cooker and the valve core 2200 abuts against the air inlet 1211, the second gas valve 4000 is opened, the gas flows into the accommodating cavity 1300 from the air inlet channel 1100 and flows into the air outlet channel 1200 from the accommodating cavity 1300 through the air inlet 1211 (in the case where the communication channel 2210 is arranged, the gas flows into the air outlet channel 1200 from the accommodating cavity 1300 through the communication channel 2210 and the air inlet 1211 in sequence), the gas flows along the air outlet channel 1200 and flows out from the second outlet 1231 to flow through the second gas valve 4000, so that the second gas valve 4000 is supplied with the gas in a normal mode, the second gas valve 4000 can adjust the gas flow to the second burner, and the gas stove can be heated in the normal mode by the second burner.

[0080] Fourthly, only the second burner heats the cooker and the valve core 2200 is separated from the air inlet 1211, the second gas valve 4000 is opened, the gas flows into the accommodating cavity 1300 from the air inlet channel 1100 and flows into the air outlet channel 1200 from the accommodating cavity 1300 through the air inlet 1211, the gas flows along the air outlet channel 1200 and flows out from the second outlet 1231 to flow through the second gas valve 4000, so that the second gas valve 4000 is supplied with the gas in a stir-frying mode, the second gas valve 4000 can adjust the gas flow to the second burner, and the gas stove can be heated in the stir-frying mode by the second burner.

[0082] The sixth, the first burner and the second burner heat the cooker, and the valve core 2200 is separated from the air inlet 1211, the first gas valve 4000 and the second gas valve 4000 are opened, the gas enters the containing cavity 1300 from the gas inlet channel 1100 and flows into the gas outlet channel 1200 from the containing cavity 1300 through the air inlet 1211, the gas flows along the gas outlet channel 1200 and flows out from the first outlet 1221 to flow through the first gas valve 3000, and flows out from the second outlet 1231 to flow through the second gas valve 4000, so as to realize the wok-hei gas supply of the first gas valve 3000 and the second gas valve 4000, the first gas valve 3000 can adjust the gas flow to the first burner, and the second gas valve 4000 can adjust the gas flow to the second burner, at this time, the gas stove can realize the wok-hei mode heating through the first burner and the second burner.

[0083] In combination Figures 7 to 14 As shown in the drawings, in some embodiments, the gas outlet channel 1200 protrudes into the containing cavity 1300, and the part of the gas outlet channel 1200 protruding into the containing cavity 1300 is provided with the air inlet 1211, that is, the periphery of the air inlet 1211 is raised relative to the cavity wall of the containing cavity 1300, which is more convenient for the sealing cooperation between the valve core 2200 and the air inlet 1211 when the valve core 2200 abuts against the air inlet 1211, especially when the valve core 2200 abuts against the periphery of the air inlet 1211 through the sealing gasket 2220, which is more conducive to the deformation of the sealing gasket 2220 and forms a better sealing effect.

[0084] In combination Figures 4 to 10 As shown in the drawings, in some embodiments, the gas inlet channel 1100 includes a first gas inlet channel 1110 and a second gas inlet channel 1120, the first gas inlet channel 1110 and the second gas inlet channel 1120 are intersected and communicated, and the second gas inlet channel 1120 is communicated with the containing cavity 1300. The first gas inlet channel 1110 is located upstream of the second gas inlet channel 1120, and the gas inlet channel 1110 can receive gas, for example, the first gas inlet channel 1110 is formed with an inlet 1111 of the gas inlet channel 1100, and a gas source can be connected to the inlet 1111 of the gas inlet channel 1100. After the gas enters the gas inlet channel 1100, it flows through the first gas inlet channel 1110 and the second gas inlet channel 1120 in sequence, and the intersection and communication of the first gas inlet channel 1110 and the second gas inlet channel 1120 are more convenient for the gas inlet channel 1100 to receive gas.

[0085] Optionally, in combination Figures 7 to 10As shown, in some embodiments, the second air inlet channel 1120 extends downward (including but not limited to directly downward, obliquely downward) from the accommodating cavity 1300, and the first air inlet channel 1110 extends rearward (including but not limited to directly rearward, obliquely rearward) from the second air inlet channel 1120. The orientation herein is with reference to the gas stove in the installed and used state, with the user standing facing the gas stove, the side of the gas stove facing the user being the front, the side away from the user being the rear, the side corresponding to the left hand of the user being the left, the side corresponding to the right hand of the user being the right, the side close to the ground being the bottom (down), and the side away from the ground being the top (up). Since the first gas valve 3000 and the second gas valve 4000 need to be arranged at the front position of the gas stove to facilitate user control, the air inlet seat 1000 needs to be arranged at the front position in cooperation with the first gas valve 3000 and the second gas valve 4000. Since the air inlet channel 1100 needs to be connected to the gas source, generally through a pipeline structure to achieve connection with the gas source, the second air inlet channel 1120 is extended downward from the accommodating cavity 1300 to avoid the control valve 2000, and the first air inlet channel 1110 of the air inlet channel 1100 is extended rearward from the second air inlet channel 1120 to facilitate connection with the gas source. Such arrangement is conducive to reducing the space occupied by the gas control device. For example, the first air inlet channel 1110 and the second air inlet channel 1120 are perpendicular

[0086] In combination Figures 4 to 6 and Figures 11 to 14As shown, in some embodiments, the gas outlet passage 1200 includes a first gas outlet passage 1210, a second gas outlet passage 1220, and a third gas outlet passage 1230, the first gas outlet passage 1210 is located upstream of the second gas outlet passage 1220 and the third gas outlet passage 1230, and the first gas outlet passage 1210 communicates the second gas outlet passage 1220 and the third gas outlet passage 1230, the first gas outlet passage 1210 is provided with an inlet 1211, the second gas outlet passage 1220 is provided with a first outlet 1221, and the third gas outlet passage 1230 is provided with a second outlet 1231. For example, the first gas outlet passage 1210 intersects the second gas outlet passage 1220, and the first gas outlet passage 1210 intersects the third gas outlet passage 1230, the gas enters the first gas outlet passage 1210 through the inlet 1211, under the premise that only the first gas valve 3000 is open, the gas flows through the second gas outlet passage 1220 and flows out from the first outlet 1221 to flow through the first gas valve 3000, under the premise that only the second gas valve 4000 is open, the gas flows through the third gas outlet passage 1230 and flows out from the second outlet 1231 to flow through the second gas valve 4000, and under the premise that the first gas valve 3000 and the second gas valve 4000 are simultaneously open, the gas flows through the second gas outlet passage 1220 and flows out from the first outlet 1221 to flow through the first gas valve 3000, and flows through the third gas outlet passage 1230 and flows out from the second outlet 1231 to flow through the second gas valve 4000. By such arrangement, the second gas outlet passage 1220 corresponds to the first gas valve 3000, and the third gas outlet passage 1230 corresponds to the second gas valve 4000, which is more conducive to flexible arrangement of the first gas valve 3000 and the second gas valve 4000, and helps to rationally utilize the space of the gas control device.

[0087] Optionally, the first gas outlet passage 1210, the second gas outlet passage 1220, and the third gas outlet passage 1230 intersect each other, which is more conducive to the arrangement of the gas path.

[0088] Since the second inlet passage 1120 and the first gas outlet passage 1210 respectively communicate with the accommodation cavity 1300, when the inlet seat 1000 is machined, the second inlet passage 1120 and / or the first gas outlet passage 1210 can be drilled through the accommodation cavity 1300 (when the first gas outlet passage 1210 is drilled, the inlet 1211 is formed at the same time), without the need to provide hole structures elsewhere to drill the second inlet passage 1120 and / or the first gas outlet passage 1210, which can reduce the number of sealing points. For example, along the extension direction of the second inlet passage 1120, the second inlet passage 1120 can be exposed at the opening 1310 of the accommodation cavity 1300, and / or along the extension direction of the first gas outlet passage 1210, the first gas outlet passage 1210 can be exposed at the opening 1310 of the accommodation cavity 1300.

[0089] Similarly, since the first gas inlet channel 1110 has the inlet 1111, the second gas outlet channel 1220 has the first outlet 1221, and the third gas outlet channel 1230 has the second outlet 1231, the first gas inlet channel 1110 can be drilled to correspondingly form the inlet 1111, the second gas outlet channel 1220 can be drilled to correspondingly form the first outlet 1221, and the third gas outlet channel 1230 can be drilled to correspondingly form the second outlet 1231. Moreover, since the inlet 1111 is used to receive gas, the first outlet 1221 is in communication with the first gas valve 3000, and the second outlet 1231 is in communication with the second gas valve 4000 to form a seal, there is no need to set a hole structure elsewhere to drill the first gas inlet channel 1110, the second gas outlet channel 1220, and / or the third gas outlet channel 1230, which can reduce the number of sealing points.

[0090] Optionally, in some embodiments, the first gas valve 3000 is located on the left side of the gas inlet seat 1000, and the second gas valve 4000 is located on the right side of the gas inlet seat 1000, which corresponds to the double-head stove design of the gas stove (double-head stove means having two burners);

[0091] The angle between the second gas outlet channel 1220 and the first gas outlet channel 1210 is an acute angle, which helps the gas control device to reasonably use space. For example, the first gas outlet channel 1210 is inclinedly arranged from the gas inlet 1211 (the accommodating cavity 1300) towards the front and lower direction to avoid the second gas inlet channel 1120, and the second gas outlet channel 1220 extends from the first gas outlet channel 1210 towards the left and rear direction to facilitate the gas to be directed to the left. The angle between the third gas outlet channel 1230 and the first gas outlet channel 1210 is a right angle, which helps the gas control device to reasonably use space. For example, the first gas outlet channel 1210 is inclinedly arranged from the gas inlet 1211 (the accommodating cavity 1300) towards the front and lower direction to avoid the second gas inlet channel 1120, and the third gas outlet channel 1230 extends from the first gas outlet channel 1210 towards the right direction to facilitate the gas to be directed to the right. The angle between the first gas outlet channel 1210 and the second gas inlet channel 1120 is an acute angle, which helps the gas control device to reasonably use space. By such arrangement, the gas control device can reduce the occupation of space volume, facilitate miniaturization design, and have a more compact structure. The angle means the smallest positive angle between two straight lines or extensions of the two straight lines.

[0092] In combination Figures 4 to 11 As shown, in some embodiments, the control valve 2000 is inclinedly arranged from the gas inlet seat 1000 towards the rear and upper direction, which can avoid occupying too much space in the up and down direction and help to control the thickness of the gas stove.

[0093] In some embodiments, the control valve 2000 is an electromagnetic valve, which can be a monostable electromagnetic valve or a bistable electromagnetic valve, facilitating the movement of the valve core 2200 to realize the opening and closing of the air inlet 1211.

[0094] In combination Figures 1 to 3 As shown, the first gas valve 3000 includes the inner ring channel 3100 and the outer ring channel 3200, and the second gas valve 4000 includes the inner ring channel 4100 and the outer ring channel 4200. The inner ring channel 3100 and the outer ring channel 3200 of the first gas valve 3000 are arranged in sequence along the first direction (for example, along the first direction to draw a circle, which can pass through the inner ring channel 3100 and the outer ring channel 3200 in sequence), and the inner ring channel 4100 and the outer ring channel 4200 of the second gas valve 4000 are arranged in sequence along the first direction (for example, along the first direction to draw a circle, which can pass through the inner ring channel 4100 and the outer ring channel 4200 in sequence). The first direction surrounds the air inlet seat 1000. As shown, Figure 3 As shown, the first direction is the counterclockwise direction facing the paper, the inner ring channel 3100 and the outer ring channel 3200 of the first gas valve 3000 are arranged in sequence along the counterclockwise direction, and the inner ring channel 4100 and the outer ring channel 4200 of the second gas valve 4000 are arranged in sequence along the counterclockwise direction. In this way, the first gas valve 3000 and the second gas valve 4000 can have consistent structures or similar structures, facilitating the production of the first gas valve 3000 and the second gas valve 4000, and facilitating the installation operation of the first gas valve 3000 and the second gas valve 4000. Moreover, since the first gas valve 3000 corresponds to the first burner, and the second gas valve 4000 corresponds to the second burner, through the cooperation of the inner ring channel 3100 / 4100 and the outer ring channel 3200 / 4200, the first burner and the second burner have consistent structures or similar structures, facilitating the cooperation of the inner ring channel 3100 and the outer ring channel 3200 of the first gas valve 3000 with the first burner respectively, and facilitating the cooperation of the inner ring channel 4100 and the outer ring channel 4200 of the second gas valve 4000 with the second burner respectively.

[0095] The second aspect of the present application discloses a gas stove, in combination Figures 1 to 15 As shown, the gas stove includes the above-mentioned gas control device, and the gas stove of the present embodiment is designed as a double-head stove, in which the first gas valve 3000 corresponds to the first burner and controls the gas supply of the first burner, and the second gas valve 4000 corresponds to the second burner and controls the gas supply of the second burner.
