[0056] The first aspect of the present application discloses a gas control device, which combines Figures 1 to 3 and Figures 7 to 14As shown, in some embodiments, the gas control device comprises an air inlet base 1000, a control valve 2000, a first gas valve 3000 and a second gas valve 4000. The air inlet base 1000 is provided with an air inlet channel 1100, a first gas outlet channel 1200 and a second gas outlet channel 1300. The first gas outlet channel 1200 is in communication with the air inlet channel 1100. The second gas outlet channel 1300 is provided with an air inlet opening 1311, which is in communication with the air inlet channel 1100, i.e. the second gas outlet channel 1300 is in communication with the air inlet channel 1100 through the air inlet opening 1311. The control valve 2000 is connected to the air inlet base 1000. The control valve 2000 comprises a valve core 2200, which is movably arranged to abut against or be separated from the air inlet opening 1311. The valve core 2200 is adapted to block part of the air inlet opening 1311 when abutting against the air inlet opening 1311. The first gas valve 3000 is connected to the air inlet base 1000 and is in communication with a first outlet 1221 of the first gas outlet channel 1200. The second gas valve 4000 is connected to the air inlet base 1000 and is in communication with a second outlet 1321 of the second gas outlet channel 1300.

[0057] The cooperation of the air inlet base 1000 and the control valve 2000 can realize normal gas supply to the first gas valve 3000 and realize normal gas supply and wok-searing gas supply to the second gas valve 4000. No structural improvement is needed for the first gas valve 3000 and the second gas valve 4000. The first gas valve 3000 and the second gas valve 4000 can adopt mature products on the market, which has strong compatibility and is conducive to reducing structural complexity and cost. Since the overall gas supply to the second gas valve 4000 can be controlled, when wok-searing gas supply is performed on the second gas valve 4000, the outer ring and the inner ring of the burner corresponding to the second gas valve 4000 can be simultaneously in the wok-searing state, and the heating of the cooker is more uniform.

[0058] Specifically, the air inlet base 1000 needs to be connected to a gas source. The gas source can be a filled liquefied gas or a pipeline natural gas. The gas source is connected to the air inlet channel 1100 of the air inlet base 1000. The gas provided by the gas source enters the inside of the air inlet base 1000 through the air inlet channel 1100 and then can be discharged through the first gas outlet channel 1200 and the second gas outlet channel 1300. The air inlet base 1000 can be an integrally formed structure or can be connected by separate components. Since the air inlet base 1000 is provided with multiple channels (the air inlet channel 1100, the first gas outlet channel 1200 and the second gas outlet channel 1300), it is more conducive to preventing gas leakage and reducing the number of sealing points to design the air inlet base 1000 as an integrally formed structure.

[0059] 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 gas inlet seat 1000 through the gas inlet channel 1100 can flow through the first gas valve 3000 and be discharged from the first gas outlet channel 1200, and the first gas valve 3000 can adjust the flow of the gas. 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 gas inlet seat 1000 through the gas inlet channel 1100 can also flow through the second gas valve 4000 and be discharged from the second gas outlet channel 1300, and the second gas valve 4000 can adjust the flow of the gas. 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 plug valves can be used for gas stoves. The first gas valve 3000 and the second gas valve 4000 are connected and fixed with the gas inlet seat 1000 by connecting means such as screw connection, welding, etc.

[0060] In the embodiment, the control valve 2000 is arranged. The gas discharged through the second gas outlet channel 1300 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 second gas valve 4000. The control valve 2000 comprises a valve core 2200, which is a movable component. The valve core 2200 has two states. The first state is that the valve core 2200 abuts against the gas inlet 1311, and the second state is that the valve core 2200 is separated from the gas inlet 1311. When the valve core 2200 abuts against the gas inlet 1311, the valve core 2200 blocks part of the gas inlet 1311. When the valve core 2200 is separated from the gas inlet 1311, the gas inlet 1311 is completely opened (relative to the state that the valve core 2200 abuts against the gas inlet 1311). That is, when the valve core 2200 abuts against the gas inlet 1311, the opening degree of the gas inlet 1311 is relatively small, so that the gas flow / pressure entering the second gas outlet channel 1300 is small. When the valve core 2200 is separated from the gas inlet 1311, the opening degree of the gas inlet 1311 is relatively large, so that the gas flow / pressure entering the second gas outlet channel 1300 is large. In this way, the normal gas supply of the second gas valve 4000 can be realized when the valve core 2200 abuts against the gas inlet 1311, and the stir-frying gas supply of the second gas valve 4000 can be realized when the valve core 2200 is separated from the gas inlet 1311 (the fire power of the stir-frying gas supply is larger than that of the normal gas supply).

[0061] The gas control device is further described by taking the gas stove as an example. The gas stove comprises the gas control device, a first burner and a second burner (not shown in the figure). The gas in the gas source flows into the interior of the air inlet seat 1000 through the air inlet channel 1100, and then flows out through the first air outlet channel 1200 and the second air outlet channel 1300. The gas flowing out through the first air outlet channel 1200 flows through the first gas valve 3000, and the gas flowing out through the second air outlet channel 1300 flows through the second gas valve 4000. The flow form of the gas is as follows:

[0062] Firstly, only the first burner is used to heat the cooker, the first gas valve 3000 is opened, the gas flows into the interior of the air inlet seat 1000 from the air inlet channel 1100 and flows into the first air outlet channel 1200, and the gas flows along the first air outlet channel 1200 and flows through the first gas valve 3000, so that the first gas valve 3000 is supplied with gas in a normal mode, and the first gas valve 3000 can adjust the gas flow to the first burner. At this time, the gas stove can realize heating in a normal mode through the first burner.

[0063] Secondly, only the second burner is used to heat the cooker and the valve core 2200 abuts against the air inlet 1311, the second gas valve 4000 is opened, the gas flows into the interior of the air inlet seat 1000 from the air inlet channel 1100 and flows into the second air outlet channel 1300 through the air inlet 1311, and the gas flows along the second air outlet channel 1300 and flows through the second gas valve 4000, so that the second gas valve 4000 is supplied with gas in a normal mode, and the second gas valve 4000 can adjust the gas flow to the second burner. At this time, the gas stove can realize heating in a normal mode through the second burner.

[0064] Thirdly, only the second burner is used to heat the cooker and the valve core 2200 is separated from the air inlet 1311, the second gas valve 4000 is opened, the gas flows into the interior of the air inlet seat 1000 from the air inlet channel 1100 and flows into the second air outlet channel 1300 through the air inlet 1311, and the gas flows along the second air outlet channel 1300 and flows through the second gas valve 4000, so that the second gas valve 4000 is supplied with gas in a blow frying mode, and the second gas valve 4000 can adjust the gas flow to the second burner. At this time, the gas stove can realize heating in a blow frying mode through the second burner.

[0065] It can be understood that the first burner and the second burner can be in a simultaneous use state, that is, simultaneously supplying gas to the first gas valve 3000 and the second gas valve 4000. When the first burner and the second burner are in the simultaneous use state, the gas stove can realize heating in the conventional mode through the first burner and the second burner, or realize heating in the conventional mode through the first burner and realize heating in the stir-frying mode through the second burner.

[0066] Generally, the first burner is provided with outer ring fire holes and inner ring fire holes, the second burner is also provided with outer ring fire holes and inner ring fire holes, the first gas valve 3000 and the second gas valve 4000 each have outer ring passages 3200 / 4200 and inner ring passages 3100 / 4100, the outer ring passages 3200 / 4200 control the gas supply of the outer ring fire holes, and the inner ring passages 3100 / 4100 control the gas supply of the inner ring fire holes. Whether the valve core 2200 abuts against the air inlet 1311 to realize conventional gas supply to the second gas valve 4000 or separates from the air inlet 1311 to realize stir-frying gas supply to the second gas valve 4000, the whole second gas valve 4000 is adjusted for gas supply. That is, when the second gas valve 4000 is supplied with gas in the conventional mode, the outer ring passage 4200 and the inner ring passage 4100 of the second gas valve 4000 can be supplied with gas in the conventional mode, and when the second gas valve 4000 is supplied with gas in the stir-frying mode, the outer ring passage 4200 and the inner ring passage 4100 of the second gas valve 4000 can be supplied with gas in the stir-frying mode. In this way, the outer ring fire holes and the inner ring fire holes of the second burner can be simultaneously in stir-frying heating or simultaneously in conventional heating, and the heating of the cookware is more uniform.

[0067] Optionally, the air 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 air inlet connection of the air inlet passage 1100.

[0068] In combination Figures 7 to 14 As shown in some embodiments, the valve core 2200 is adapted to abut against the periphery of the air inlet 1311, and the valve core 2200 is provided with a communication passage 2210 adapted to communicate the air inlet passage 1100 and the remaining part of the air inlet 1311 when the valve core 2200 abuts against the periphery of the air inlet 1311. By abutting the valve core 2200 against the periphery of the air inlet 1311, the force acting on the valve core 2200 (the reaction force applied by the periphery of the air inlet 1311) is more uniform, which helps to improve the effect of the valve core 2200 plugging the part of the air inlet 1311, avoid leakage and ensure conventional gas supply. Since the valve core 2200 is movable, the more uniform force acting 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 against the periphery of the air inlet 1311, one end of the communication passage 2210 communicates with the remaining part of the air inlet 1311, and the other end of the communication passage 2210 communicates with the air inlet passage 1100 (the cross-sectional size of the communication passage 2210 can be set according to the firepower required by conventional heating). In combination with Figures 7 to 14 As shown, one end of the communication passage 2210 is located at the middle of the valve core 2200, so that when the valve core 2200 abuts against the periphery of the air inlet 1311, the communication passage 2210 and the remaining part of the air inlet 1311 are communicated, that is, the communication passage 2210 is communicated with the second air outlet passage 1300, and since the other end of the communication passage 2210 is communicated with the air inlet passage 1100, the air inlet passage 1100 and the second air outlet passage 1300 are communicated. When the valve core 2200 abuts against the periphery of the air inlet 1311, the gas enters the inside of the air inlet seat 1000 from the air inlet passage 1100 and flows through the communication passage 2210, the remaining part of the air inlet 1311, and then flows into the second air outlet passage 1300.

[0070] Optionally, in combination with Figures 7 to 14 As shown, the valve core 2200 can be provided with a sealing gasket 2220, and the valve core 2200 abuts against the periphery of the air inlet 1311 through the sealing gasket 2220. The sealing gasket 2220 is suitable for elastic deformation, 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 passage 2210.

[0071] In combination with Figures 7 to 14 As shown, in some embodiments, the communication passage 2210 includes a first communication passage 2211 and a second communication passage 2212, and the first communication passage 2211 and the second communication passage 2212 are intersected and communicated (the intersection means that the two are not on the same straight line, and the same applies below). The communication passage 2210 is suitable for being communicated with the air inlet passage 1100 through the first communication passage 2211, and the communication passage 2210 is suitable for being communicated with the remaining part of the air inlet 1311 through the second communication passage 2212. Through the intersected and communicated first communication passage 2211 and the second communication passage 2212, the arrangement and cooperation of various structures are more convenient. The so-called intersected and communicated means that the two are not straight but form an included angle, and the same applies below.

[0072] For example, the valve core 2200 is designed to be reciprocally movable along its axial direction, the air inlet 1311 is located in the axial direction of the valve core 2200, the valve core 2200 moves towards the air inlet 1311 so as to abut against the air inlet 1311, and moves away from the air inlet 1311 so as to be separated from the air inlet 1311, on the basis of which, by arranging 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 1311, the gas flows through the first communication passage 2211 and the second communication passage 2212 in sequence so as to enter the second air outlet passage 1300 through the air inlet 1311, in this way, the valve core 2200 can not only realize plugging of the air inlet 1311, but also realize communication between the air inlet passage 1100 and the second air outlet passage 1300, 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.

[0073] In combination Figures 7 to 15 As shown in the drawings, in some embodiments, the air inlet seat 1000 is provided with a containing cavity 1400, the air inlet passage 1100 communicates with the containing cavity 1400, the first air outlet passage 1200 communicates with the containing cavity 1400, the air inlet 1311 communicates with the containing cavity 1400, that is, the second air outlet passage 1300 communicates with the containing cavity 1400 through the air inlet 1311, and the valve core 2200 is movably arranged in the containing cavity 1400.

[0074] It can be understood that the air inlet passage 1100 communicating with the containing cavity 1400 means that the gas flows from the air inlet passage 1100 into the containing cavity 1400 (the gas flowing along the air inlet passage 1100 flows into the containing cavity 1400), the first air outlet passage 1200 communicating with the containing cavity 1400 means that the gas flows from the containing cavity 1400 into the first air outlet passage 1200 (the gas flowing into the containing cavity 1400 continues to flow into the first air outlet passage 1200), and the air inlet 1311 communicating with the containing cavity 1400 means that the gas flows from the containing cavity 1400 into the second air outlet passage 1300 (the gas flowing into the containing cavity 1400 continues to flow into the second air outlet passage 1300).

[0075] The setting of the accommodating cavity 1400 facilitates 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). For example, the accommodating cavity 1400 has an opening 1410, the control valve 2000 is mounted to the gas inlet seat 1000 in alignment with the opening 1410, the valve core 2200 is inserted into the accommodating cavity 1400 through the opening 1410, and the valve core 2200 can move in the accommodating cavity 1400. The control valve 2000 is fixedly connected to the gas inlet seat 1000 to cover the opening 1410, thereby sealing the accommodating cavity 1400.

[0076] With the setting of the accommodating cavity 1400, the gas flow is as follows:

[0077] First, only the first burner is used to heat the cooker, the first gas valve 3000 is opened, the gas flows from the gas inlet passage 1100 into the accommodating cavity 1400 and then flows from the accommodating cavity 1400 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, and 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.

[0078] Second, only the second burner is used to heat the cooker and the valve core 2200 abuts against the gas inlet port 1311, the second gas valve 4000 is opened, the gas flows from the gas inlet passage 1100 into the accommodating cavity 1400 and then flows from the accommodating cavity 1400 into the second gas outlet passage 1300 through the gas inlet port 1311 (in the case of the setting of the communication passage 2210, the gas flows from the accommodating cavity 1400 into the second gas outlet passage 1300 through the communication passage 2210 and the gas inlet port 1311 in sequence), the gas flows along the second gas outlet passage 1300 and passes through the second gas valve 4000, thereby achieving normal gas supply to the second gas valve 4000, and the second gas valve 4000 can adjust the gas flow to the second burner. At this time, the gas stove can heat in the normal mode through the second burner.

[0079] Third, only the second burner is used to heat the cooker and the valve core 2200 is separated from the gas inlet port 1311, the second gas valve 4000 is opened, the gas flows from the gas inlet passage 1100 into the accommodating cavity 1400 and then flows from the accommodating cavity 1400 into the second gas outlet passage 1300 through the gas inlet port 1311, the gas flows along the second gas outlet passage 1300 and passes through the second gas valve 4000, thereby achieving explosive frying gas supply to the second gas valve 4000, and the second gas valve 4000 can adjust the gas flow to the second burner. At this time, the gas stove can heat in the explosive frying mode through the second burner.

[0080] It can be understood that the first burner and the second burner can be in a simultaneous use state, and the flow of the gas is a combination of the first scheme and the second scheme or the third scheme, which will not be repeated.

[0081] In combination Figures 7 to 14 It is shown that, in some embodiments, the second air outlet channel 1300 protrudes into the accommodating cavity 1400, and the part of the second air outlet channel 1300 protruding into the accommodating cavity 1400 is provided with the air inlet 1311, that is, the periphery of the air inlet 1311 is raised relative to the cavity wall of the accommodating cavity 1400, which is more convenient for the sealing cooperation between the valve core 2200 and the air inlet 1311 when the valve core 2200 abuts against the air inlet 1311, especially when the valve core 2200 abuts against the periphery of the air inlet 1311 through the sealing gasket 2220, which is more conducive to the deformation of the sealing gasket 2220, thereby forming a better sealing effect.

[0082] In combination Figures 4 to 10 It is shown that, in some embodiments, the air inlet channel 1100 includes a first air inlet channel 1110 and a second air inlet channel 1120, the first air inlet channel 1110 and the second air inlet channel 1120 are intersected and communicated, and the second air inlet channel 1120 is communicated with the accommodating cavity 1400. The first air inlet channel 1110 is located upstream of the second air inlet channel 1120, and the gas can be received through the first air inlet channel 1110, for example, the first air inlet channel 1110 is formed with an inlet 1111 of the air inlet channel 1100, and the gas source can be connected to the inlet 1111 of the air inlet channel 1100. After the gas enters the air inlet channel 1100, it flows through the first air inlet channel 1110 and the second air inlet channel 1120 in sequence, and the intersection and communication of the first air inlet channel 1110 and the second air inlet channel 1120 are more convenient for the air inlet channel 1100 to receive the gas.

[0083] 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 1400, 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 1400 to avoid the control valve 2000, and the first air inlet channel 1110 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 occupation of the gas control device, for example, the first air inlet channel 1110 and the second air inlet channel 1120 are perpendicular.

[0084] In combination Figures 4 to 15 As shown, in some embodiments, the first air outlet channel 1200 includes a first upstream channel 1210 and a first downstream channel 1220, i.e., the first upstream channel 1210 is located upstream of the first downstream channel 1220, the first upstream channel 1210 communicates with the accommodating cavity 1400, 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 air outlet channel 1300 includes a second upstream channel 1310 and a second downstream channel 1320, i.e., the second upstream channel 1310 is located upstream of the second downstream channel 1320, the second upstream channel 1310 is provided with an air inlet 1311, 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, it is more convenient for the arrangement of the first gas valve 3000 and the second gas valve 4000, and it is helpful to reduce the space occupation of the gas control device.

[0085] Since the second air inlet channel 1120, the first upstream channel 1210 and the second upstream channel 1310 are respectively communicated with the accommodating cavity 1400, when the air inlet base 1000 is machined, the second air inlet channel 1120, the first upstream channel 1210 and / or the second upstream channel 1310 can be drilled through the accommodating cavity 1400 (when the second upstream channel 1310 is drilled, the air inlet 1311 is simultaneously formed), without the need to set hole structures in other places to drill the second air inlet channel 1120, the first upstream channel 1210 and / or the second upstream channel 1310, so as to reduce 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 1410 of the accommodating cavity 1400, and / or along the extension direction of the first upstream channel 1210, the first upstream channel 1210 can be exposed at the opening 1410 of the accommodating cavity 1400, and / or along the extension direction of the second upstream channel 1310, the second upstream channel 1310 can be exposed at the opening 1410 of the accommodating cavity 1400.

[0086] 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, drilling the first air inlet channel 1110 can correspondingly form the inlet 1111, drilling the first downstream channel 1220 can correspondingly form the first outlet 1221, and drilling the second downstream channel 1320 can correspondingly form the second outlet 1321, 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, so as to reduce the number of sealing points.

[0087] Optionally, in combination with Figures 1 to 16 As shown in the figure, in some embodiments, the first gas valve 3000 is located on the left side of the air inlet base 1000, and the second gas valve 4000 is located on the right side of the air inlet base 1000, so as to correspond to the double-head stove design of the gas stove (double-head stove means having two burners):

[0088] The first upstream passage 1210 is perpendicular to the first downstream passage 1220, which helps the gas control device to reasonably use space. For example, the first upstream passage 1210 extends obliquely from the accommodating cavity 1400 towards the lower left, which facilitates the gas to be directed to the left, and the first downstream passage 1220 extends from the first upstream passage 1210 towards the left rear. The second upstream passage 1310 is perpendicular to the second downstream passage 1320, which helps the gas control device to reasonably use space. For example, the second upstream passage 1310 extends obliquely from the accommodating cavity 1400 towards the lower front, avoiding the second gas inlet passage 1120, and the second downstream passage 1320 extends from the second upstream passage 1310 towards the right, which facilitates the gas to be directed to the right. The included angle between the second upstream passage 1310 and the second gas inlet passage 1120 is an acute angle, which helps the gas control device to reasonably use space. The second upstream passage 1310 is coaxially arranged with the second communication passage 2212 and coplanarly arranged with the second downstream passage 1320, which is conducive to realizing the abutment of the valve core 2200 to the gas inlet 1311 under the premise of making the gas control device reasonably use space. Through such arrangement, it is conducive to reducing the space volume occupied by the gas control device, facilitating miniaturized 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.

[0089] Optionally, in combination with Figures 4 to 10 and Figure 17 shown, in some embodiments, the first gas valve 3000 is located on the right side of the gas inlet seat 1000, and the second gas valve 4000 is located on the left side of the gas inlet seat 1000, which corresponds to the double-head stove design of the gas stove:

[0090] The included angle between the first upstream passage 1210 and the first downstream passage 1220 is an acute angle, which helps the gas control device to reasonably use space. For example, the first upstream passage 1210 is arranged obliquely from the accommodating cavity 1400 towards the lower right, which facilitates the gas to be directed to the right, and the first downstream passage 1220 extends from the first upstream passage 1210 towards the right. The included angle between the second upstream passage 1310 and the second downstream passage 1320 is an acute angle, which helps the gas control device to reasonably use space. For example, the second upstream passage 1310 is arranged obliquely from the accommodating cavity 1400 towards the lower front, avoiding the second gas inlet passage 1120, and the second downstream passage 1320 extends from the second upstream passage 1310 towards the left rear. The included angle between the second upstream passage 1310 and the second gas inlet passage 1120 is an acute angle, which helps the gas control device to reasonably use space. The second upstream passage 1310 is coaxially arranged with the second communication passage 2212, which is conducive to realizing the abutment of the valve core 2200 to the gas inlet 1311 under the premise of making the gas control device reasonably use space. Through such arrangement, it is conducive to reducing the space volume occupied by the gas control device, facilitating miniaturized design, and the structure is more compact.

[0091] , in combination withFigures 4 to 10 As shown, in some embodiments, the control valve 2000 is arranged to tilt towards the rear and upper direction of the air inlet base 1000, so as to avoid occupying too much space in the up-down direction, and to help control the thickness of the gas stove.

[0092] In some embodiments, the control valve 2000 is a solenoid valve, which can be a monostable solenoid valve or a bistable solenoid valve, to facilitate the movement of the valve core 2200 to achieve the opening and closing of the air inlet 1311.

[0093] In combination with Figures 1 to 3 As shown, 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 (e.g., 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 (e.g., 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 base 1000. For example, Figure 3 As shown, the first direction is the counterclockwise direction 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, 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.

[0094] The second aspect of the present application discloses a gas stove, in combination with Figures 1 to 17As shown, the gas stove comprises the above-mentioned gas control device, and the gas stove of the embodiment is designed as a double-cooktop, wherein 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 embodiment adopts the technical solutions of the above-mentioned embodiments, and thus at least has the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0095] The above merely describes the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
