[0053] The first aspect of the present application discloses a gas control device, which combines Figures 1 to 15As shown, 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, a first air outlet channel 1200, a second air outlet channel 1300 and an auxiliary channel 1400. The first air outlet channel 1200 is in communication with the air inlet channel 1100, the second air outlet channel 1300 is in communication with the air inlet channel 1100, the auxiliary channel 1400 is in communication with the first air outlet channel 1200 so that gas can flow from the auxiliary channel 1400 to the first air outlet channel 1200, and the auxiliary channel 1400 is also in communication with the second air outlet channel 1300 so that gas can flow from the auxiliary channel 1400 to the second air outlet channel 1300. The auxiliary channel 1400 is provided with an air inlet 1410. The control valve 2000 is connected to the air inlet seat 1000. The control valve 2000 comprises a valve core 2200 which is movably arranged so as to abut or be separated from the air inlet 1410. When the valve core 2200 abuts the air inlet 1410, the valve core 2200 closes the air inlet 1410. When the valve core 2200 is separated from the air inlet 1410, the valve core 2200 opens the air inlet 1410. When the valve core 2200 opens the air inlet 1410, the air inlet 1410 is in communication with the air inlet channel 1100. The first gas valve 3000 is connected to the air inlet seat 1000 and is in communication with a first outlet 1221 of the first air outlet channel 1200. The second gas valve 4000 is connected to the air inlet seat 1000 and is in communication with a second outlet 1321 of the second air outlet channel 1300.

[0054] In the present embodiment, the air inlet seat 1000 is provided with the first air outlet channel 1200, the second air outlet channel 1300 and the auxiliary channel 1400. The auxiliary channel 1400 can be in communication with the first air outlet channel 1200 and the second air outlet channel 1300 at the same time. By cooperating the control valve 2000 with the first air outlet channel 1200, the second air outlet channel 1300 and the auxiliary channel 1400, the conventional gas supply and the stir-frying gas supply for the first gas valve 3000 can be realized, and the conventional gas supply and the stir-frying gas supply for the second gas valve 4000 can be realized. 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.

[0055] 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 be discharged through the first gas outlet channel 1200 and the second gas outlet channel 1300. 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 multiple channels (the gas inlet channel 1100, the first gas outlet channel 1200, the second gas outlet channel 1300, and the auxiliary channel 1400), 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.

[0056] The first gas valve 3000 is connected with the gas inlet seat 1000 and communicates with the first outlet 1221 of the first gas outlet channel 1200. The gas entering the interior of the gas inlet seat 1000 through the gas inlet channel 1100 can be discharged from the first gas outlet channel 1200 to flow through the first gas valve 3000, 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 1321 of the second gas outlet channel 1300. The gas entering the interior of the gas inlet seat 1000 through the gas inlet channel 1100 can also be discharged from the second gas outlet channel 1300 to flow through the second gas valve 4000, 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.

[0057] In the embodiment, the air inlet seat 1000 is provided with an auxiliary channel 1400, and the auxiliary channel 1400 needs to cooperate with 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 switching of the normal gas supply and the stir-frying gas supply of the second gas valve 4000. The auxiliary channel 1400 is in communication with the first gas outlet channel 1200 so that the gas can flow from the auxiliary channel 1400 to the first gas outlet channel 1200, the auxiliary channel 1400 is also in communication with the second gas outlet channel 1300 so that the gas can flow from the auxiliary channel 1400 to the second gas outlet channel 1300, and the auxiliary channel 1400 is provided with an air inlet 1410, and the control valve 2000 comprises a valve core 2200, which is a movable component, and the movement of the valve core 2200 has two states, the first state is that the valve core 2200 abuts against the air inlet 1410, and the second state is that the valve core 2200 is separated from the air inlet 1410. When the valve core 2200 abuts against the air inlet 1410, the valve core 2200 closes the air inlet 1410 (that is, the auxiliary channel 1400 is closed), and when the valve core 2200 is separated from the air inlet 1410, the valve core 2200 opens the air inlet 1410 (that is, the auxiliary channel 1400 is opened). Since the first gas outlet channel 1200 is in communication with the air inlet channel 1100, and the second gas outlet channel 1300 is in communication with the air inlet channel 1100, no matter whether the valve core 2200 abuts against the air inlet 1410 or is separated from the air inlet 1410, the gas can be discharged through the first gas outlet channel 1200 and the second gas outlet channel 1300, but when the valve core 2200 is separated from the air inlet 1410, the gas can also flow into the first gas outlet channel 1200 and the second gas outlet channel 1300 through the auxiliary channel 1400, so that the gas flow / pressure entering the first gas outlet channel 1200 is increased, and the gas flow / pressure entering the second gas outlet channel 1300 is increased, and when the valve core 2200 abuts against the air inlet 1410, the gas cannot flow into the first gas outlet channel 1200 and the second gas outlet channel 1300 through the auxiliary channel 1400, so that the gas flow / pressure entering the first gas outlet channel 1200 and the second gas outlet channel 1300 is reduced, that is, the normal gas supply of the first gas valve 3000 and the second gas valve 4000 can be realized when the valve core 2200 abuts against the air inlet 1410, and the stir-frying 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 air inlet 1410 (the fire power of the stir-frying gas supply is greater than that of the normal gas supply).

[0058] 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 air inlet channel 1100 of the air inlet seat 1000 is connected to a gas source, the first gas valve 3000 controls the gas flow to the first burner, and the second gas valve 4000 controls the gas flow to the second burner.

[0063] Fifth, the first burner and the second burner heat the cookware, and the valve core 2200 abuts against the air inlet 1410, the first gas valve 3000 and the second gas valve 4000 are opened, the gas enters the interior of the air inlet seat 1000 from the air inlet channel 1100 and flows into the first gas outlet channel 1200 and the second gas outlet channel 1300 from the interior of the air inlet seat 1000, so as to realize the normal 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, the second gas valve 4000 can adjust the gas flow to the second burner, and the gas stove can realize the heating in the normal mode through the first burner and the second burner.

[0064] Sixth, the first burner and the second burner heat the cookware, and the valve core 2200 is separated from the air inlet 1410, the first gas valve 3000 and the second gas valve 4000 are opened, the gas enters the interior of the air inlet seat 1000 from the air inlet channel 1100 and flows into the first gas outlet channel 1200 and the second gas outlet channel 1300 from the interior of the air inlet seat 1000, and flows into the first gas outlet channel 1200 and the second gas outlet channel 1300 from the auxiliary channel 1400 through the air inlet 1410 (that is, compared with the case that the valve core 2200 abuts against the air inlet 1410, the gas flows into the first gas outlet channel 1200 and the second gas outlet channel 1300 through the auxiliary channel 1400), so as to realize the explosive frying 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, the second gas valve 4000 can adjust the gas flow to the second burner, and the gas stove can realize the heating in the explosive frying mode through the first burner and the second burner.

[0065] Generally, the first burner is provided with inner and outer annular flame holes, the second burner is also provided with inner and outer annular flame holes, the first gas valve 3000 and the second gas valve 4000 each have inner annular passages 3100 / 4100 and outer annular passages 3200 / 4200, the inner annular passages 3100 / 4100 control the gas supply of the inner annular flame holes, the outer annular passages 3200 / 4200 control the gas supply of the outer annular flame holes, whether the valve core 2200 abuts the gas inlet 1410 or separates from the gas inlet 1410, the gas supply of the first gas valve 3000 and the second gas valve 4000 is adjusted as a whole, that is, when the first gas valve 3000 is supplied with regular gas, the outer annular passages 3200 and the inner annular passages 3100 of the first gas valve 3000 can be supplied with regular gas, when the first gas valve 3000 is supplied with explosive frying gas, the outer annular passages 3200 and the inner annular passages 3100 of the first gas valve 3000 can be supplied with explosive frying gas, so that the outer annular flame holes and the inner annular flame holes of the first burner can be heated by explosive frying or regular heating at the same time, the heating of the cooker is more uniform, and the same is true for the second gas valve 4000, which will not be repeated here.

[0066] Optionally, the gas inlet passage 1100 is located between the first gas valve 3000 and the second gas valve 4000, which is beneficial to rational use of space and more convenient for gas inlet connection of the gas inlet passage 1100.

[0069] The accommodation cavity 1500 is arranged to facilitate the movement of the valve core 2200 and the communication between the passages (the gas inlet passage 1100 and the first gas outlet passage 1200, the gas inlet passage 1100 and the second gas outlet passage 1300, and the gas inlet passage 1100 and the auxiliary passage 1400). For example, the accommodation cavity 1500 has an opening 1510, the control valve 2000 is arranged to cover the opening 1510 and is fixed to the gas inlet seat 1000, the valve core 2200 is inserted into the accommodation cavity 1500 through the opening 1510, and the valve core 2200 can move in the accommodation cavity 1500. The control valve 2000 is fixed to the gas inlet seat 1000 to cover the opening 1510, thereby sealing the accommodation cavity 1500.

[0070] With the arrangement of the accommodation cavity 1500, the gas flow is as follows:

[0071] First, only the first burner is used to heat the cooker, and the valve core 2200 abuts against the gas inlet 1410. The first burner is turned on, the gas flows from the gas inlet passage 1100 into the accommodation cavity 1500 and then flows from the accommodation cavity 1500 into the first gas outlet passage 1200. The gas flows along the first gas outlet passage 1200 and passes through the first gas valve 3000, thereby achieving normal gas supply to the first gas valve 3000. The first gas valve 3000 can adjust the gas flow to the first burner. At this time, the gas stove can heat in the normal mode through the first burner.

[0072] Second, only the first burner is used to heat the cooker, and the valve core 2200 is separated from the gas inlet 1410. The first gas valve 3000 is turned on, the gas flows from the gas inlet passage 1100 into the accommodation cavity 1500 and then flows from the accommodation cavity 1500 into the first gas outlet passage 1200, and then flows from the accommodation cavity 1500 into the auxiliary passage 1400 through the gas inlet 1410 and then flows from the auxiliary passage 1400 into the first gas outlet passage 1200 (i.e., compared with the case where the valve core 2200 abuts against the gas inlet 1410, an additional path is added, i.e., the gas flows from the auxiliary passage 1400 into the first gas outlet passage 1200). Thus, the first gas valve 3000 is supplied with gas for explosive frying. The first gas valve 3000 can adjust the gas flow to the first burner. At this time, the gas stove can heat in the explosive frying mode through the first burner.

[0073] Third, only through the second burner heating cookware and valve core 2200 abutment inlet 1410, open the second burner, gas from the gas inlet channel 1100 into the cavity 1500 and from the cavity 1500 into the second gas outlet channel 1300, gas along the second gas outlet channel 1300 and flow through the second gas valve 4000, so as to achieve the second gas valve 4000 regular gas supply, the second gas valve 4000 can adjust the flow of gas to the second burner, the gas stove can be through the second burner to achieve the heating of the conventional mode.

[0074] Fourth, only through the second burner heating cookware and valve core 2200 away from the inlet 1410, open the second gas valve 4000, gas from the gas inlet channel 1100 into the cavity 1500 and from the cavity 1500 into the second gas outlet channel 1300, and from the cavity 1500 through the inlet 1410 into the auxiliary channel 1400 and then from the auxiliary channel 1400 into the second gas outlet channel 1300 (ie, relative to the valve core 2200 abutment inlet 1410, increased gas through the auxiliary channel 1400 into the second gas outlet channel 1300 this path), so as to achieve the second gas valve 4000 wok gas supply, the second gas valve 4000 can adjust the flow of gas to the second burner, the gas stove can be through the second burner to achieve the heating of the wok mode.

[0075] Fifth, through the first burner and the second burner heating cookware and valve core 2200 abutment inlet 1410, open the first gas valve 3000 and the second gas valve 4000, gas from the gas inlet channel 1100 into the cavity 1500 and from the cavity 1500 into the first gas outlet channel 1200 and the second gas outlet channel 1300, so as to achieve the first gas valve 3000 and the second gas valve 4000 regular gas supply, the first gas valve 3000 can adjust the flow of gas to the first burner, the second gas valve 4000 can adjust the flow of gas to the second burner, the gas stove can be through the first burner and the second burner to achieve the heating of the conventional mode.

[0076] In the sixth mode, the cooktop is heated by the first burner and the second burner, the valve core 2200 is separated from the air inlet 1410, the first gas valve 3000 and the second gas valve 4000 are opened, the gas enters the accommodating cavity 1500 from the gas inlet channel 1100 and flows into the first gas outlet channel 1200 and the second gas outlet channel 1300 from the accommodating cavity 1500, and then flows into the first gas outlet channel 1200 and the second gas outlet channel 1300 from the auxiliary channel 1400 (that is, in addition to the path of the gas flowing into the first gas outlet channel 1200 and the second gas outlet channel 1300 from the auxiliary channel 1400, the gas also flows into the first gas outlet channel 1200 and the second gas outlet channel 1300 from the air inlet 1410 when the valve core 2200 abuts against the air inlet 1410), 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 heating of the wok-hei mode through the first burner and the second burner.

[0077] In combination Figures 8 to 11 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 intersect and communicate with each other (the intersection means that the two are not on the same straight line, and the same applies below), the first gas inlet channel 1110 forms an inlet 1111 of the gas inlet channel 1100, and the second gas inlet channel 1120 communicates with the accommodating cavity 1500. The first gas inlet channel 1110 is located upstream of the second gas inlet channel 1120, and the gas can be received through the first gas inlet channel 1110, for example, the first gas inlet channel 1110 forms the inlet 1111 of the gas inlet channel 1100, and the 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 turn. Through the intersection and communication of the first gas inlet channel 1110 and the second gas inlet channel 1120, it is more convenient for the gas inlet channel 1100 to receive gas.

[0078] Optionally, in some embodiments, the second gas inlet channel 1120 extends downward (including but not limited to directly downward, obliquely downward) from the accommodating cavity 1500, and the first gas inlet channel 1110 extends rearward (including but not limited to directly rearward, obliquely rearward) from the second gas 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 gas 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 gas inlet channel 1100 needs to be connected to the gas source, generally through a pipeline structure to achieve connection to the gas source, the second gas inlet channel 1120 is extended downward from the accommodating cavity 1500 to avoid the control valve 2000, and the first gas inlet channel 1110 is extended rearward from the second gas inlet channel 1120 to facilitate connection to the gas source. Such arrangement is conducive to reducing the space occupation of the gas control device, for example, the first gas inlet channel 1110 and the second gas inlet channel 1120 are perpendicular.

[0079] In combination Figures 12 to 15 As shown in some embodiments, the first gas outlet channel 1200 includes a first upstream channel 1210 and a first downstream channel 1220, i.e., the first upstream channel 1210 is upstream of the first downstream channel 1220, the first upstream channel 1210 communicates with the accommodating cavity 1500, the first downstream channel 1220 intersects and communicates with the first upstream channel 1210, and the first downstream channel 1220 is provided with a first outlet 1221, and the gas flows through the first upstream channel 1210 and the first downstream channel 1220 in sequence; the second gas outlet channel 1300 includes a second upstream channel 1310 and a second downstream channel 1320, i.e., the second upstream channel 1310 is upstream of the second downstream channel 1320, the second upstream channel 1310 communicates with the accommodating cavity 1500, the second downstream channel 1320 intersects and communicates with the second upstream channel 1310, and the second downstream channel 1320 is provided with a second outlet 1321, and the gas flows through the second upstream channel 1310 and the second downstream channel 1320 in sequence. By such arrangement, the arrangement of the first gas valve 3000 and the second gas valve 4000 is more convenient, which helps to reduce the space occupation of the gas control device.

[0080] In combination Figures 12 to 15As shown, in some embodiments, the auxiliary channel 1400 is in communication with the first downstream channel 1220 (e.g., intersecting communication), and the auxiliary channel 1400 is also in communication with the second downstream channel 1320 (e.g., intersecting communication), the gas flow entering the first upstream channel 1210 flows to the first downstream channel 1220, the gas flow entering the second upstream channel 1310 flows to the second downstream channel 1320, and the gas flow entering the auxiliary channel 1400 flows to the first downstream channel 1220 and the second downstream channel 1320, which is more convenient for the arrangement of the gas path and helps to rationally utilize the space, for example, the first downstream channel 1220 extends from the auxiliary channel 1400 towards the left rear to facilitate cooperation with the first gas valve 3000 located on the left side, and the second downstream channel 1320 extends from the auxiliary channel 1400 towards the right to facilitate cooperation with the second gas valve 4000 located on the right side. Optionally, the auxiliary channel 1400, the first downstream channel 1220 and the second downstream channel 1320 intersect each other, further optimizing the utilization of space (the cross-sectional size of the first upstream channel 1210 and the second upstream channel 1310 can be set according to the firepower required for conventional heating).

[0081] In combination Figures 4 to 15 As shown, 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):

[0082] The included angle between the auxiliary channel 1400 and the second gas inlet channel 1120 of the gas inlet channel 1100 is an acute angle, which helps the gas control device to rationally utilize the space, for example, the auxiliary channel 1400 extends obliquely from the containing cavity 1500 towards the lower front to avoid the control valve 2000, and the second gas inlet channel 1120 extends downwards from the containing cavity 1500. The included angle between the first upstream channel 1210 and the first downstream channel 1220 is an acute angle, which helps the gas control device to rationally utilize the space, for example, the first upstream channel 1210 extends obliquely from the containing cavity 1500 towards the lower left, and the first downstream channel 1220 extends from the first upstream channel 1210 towards the left rear. The included angle between the second upstream channel 1310 and the second downstream channel 1320 of the second gas outlet channel 1300 is an acute angle, which helps the gas control device to rationally utilize the space, for example, the second upstream channel 1310 extends obliquely from the containing cavity 1500 towards the lower right, and the second downstream channel 1320 extends from the second upstream channel 1310 towards the right. The included angle between the auxiliary channel 1400 and the first upstream channel 1210 is an acute angle, and the included angle between the auxiliary channel 1400 and the second upstream channel 1310 is an acute angle, which helps the gas control device to rationally utilize the space. By such arrangement, it is conducive to the gas control device to reduce the occupation of the space volume and facilitate miniaturization design, and the structure is more compact. The included angle means the smallest positive angle between two straight lines or extensions of two straight lines.

[0083] In combination Figures 8 to 15 As shown in some embodiments, the auxiliary channel 1400 protrudes into the accommodating cavity 1500, and the portion of the auxiliary channel 1400 protruding into the accommodating cavity 1500 is provided with the air inlet 1410, that is, the periphery of the air inlet 1410 is raised relative to the cavity wall of the accommodating cavity 1500, which is more convenient for the sealing cooperation between the valve core 2200 and the air inlet 1410 when the valve core 2200 abuts against the air inlet 1410, especially when the valve core 2200 abuts against the periphery of the air inlet 1410 through the sealing gasket 2210, which is more conducive to the deformation of the sealing gasket 2210, thereby forming a better sealing effect.

[0084] Since the second air inlet channel 1120, the first upstream channel 1210, the second upstream channel 1310, and the auxiliary channel 1400 are respectively communicated with the accommodating cavity 1500, when the air inlet seat 1000 is machined, the second air inlet channel 1120, the first upstream channel 1210, the second upstream channel 1310, and the auxiliary channel 1400 can be drilled through the accommodating cavity 1500 (when the auxiliary channel 1400 is drilled, the air inlet 1410 is formed at the same time), without the need to set hole structures in other places to drill the second air inlet channel 1120, the first upstream channel 1210, the second upstream channel 1310, and / or the auxiliary channel 1400, thereby reducing the number of sealing points. For example, along the extension direction of the second air inlet channel 1120, the second air inlet channel 1120 can be exposed at the opening 1510 of the accommodating cavity 1500, and / or along the extension direction of the first upstream channel 1210, the first upstream channel 1210 can be exposed at the opening 1510 of the accommodating cavity 1500, and / or along the extension direction of the second upstream channel 1310, the second upstream channel 1310 can be exposed at the opening 1510 of the accommodating cavity 1500, and / or along the extension direction of the auxiliary channel 1400, the auxiliary channel 1400 can be exposed at the opening 1510 of the accommodating cavity 1500.

[0085] Similarly, since the first air inlet channel 1110 has the inlet 1111, the first downstream channel 1220 has the first outlet 1221, and the second downstream channel 1320 has the second outlet 1321, the inlet 1111 can be formed correspondingly when the first air inlet channel 1110 is drilled, the first outlet 1221 can be formed correspondingly when the first downstream channel 1220 is drilled, and the second outlet 1321 can be formed correspondingly when the second downstream channel 1320 is drilled, and since the inlet 1111 is used to receive gas, the first outlet 1221 is communicated with the first gas valve 3000, and the second outlet 1321 is communicated with the second gas valve 4000 to form a seal, without the need to set hole structures in other places to drill the first air inlet channel 1110, the first downstream channel 1220, and / or the second downstream channel 1320, thereby reducing the number of sealing points.

[0086] 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 1410.

[0087] In combination Figures 1 to 3 As shown in the figure, the first gas valve 3000 includes an inner ring passage 3100 and an outer ring passage 3200, and the second gas valve 4000 includes an inner ring passage 4100 and an outer ring passage 4200. The inner ring passage 3100 and the outer ring passage 3200 of the first gas valve 3000 are arranged in sequence along a first direction (for example, along the first direction to draw a circle, which can pass through the inner ring passage 3100 and the outer ring passage 3200 in sequence), and the inner ring passage 4100 and the outer ring passage 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 passage 4100 and the outer ring passage 4200 in sequence). The first direction surrounds the air inlet seat 1000. As shown in the figure, Figure 3 The first direction is counterclockwise facing the paper, the inner ring passage 3100 and the outer ring passage 3200 of the first gas valve 3000 are arranged in sequence along the counterclockwise direction, and the inner ring passage 4100 and the outer ring passage 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 passage 3100 / 4100 and the outer ring passage 3200 / 4200, the first burner and the second burner have consistent structures or similar structures, facilitating the cooperation of the inner ring passage 3100 and the outer ring passage 3200 of the first gas valve 3000 with the first burner respectively, and facilitating the cooperation of the inner ring passage 4100 and the outer ring passage 4200 of the second gas valve 4000 with the second burner respectively.

[0088] The second aspect of the present application discloses a gas stove, in combination Figures 1 to 15 As shown in the figure, 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. It can be understood that the gas control device of the gas stove of the present embodiment adopts the technical solutions of the above-mentioned embodiments, and therefore at least has the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0089] The above merely describes the preferred embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent structural changes made according to the content of the present application specification and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
