[0056] 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 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, a second gas outlet channel 1300 and an auxiliary channel 1400. The first gas outlet channel 1200 is in communication with the air inlet channel 1100, the second gas outlet channel 1300 is in communication with the air inlet channel 1100, and the auxiliary channel 1400 is in communication with the second gas outlet channel 1300 so that gas can flow from the auxiliary channel 1400 to the second gas outlet channel 1300. The auxiliary channel 1400 is provided with an air inlet port 1410. The control valve 2000 is connected to the air inlet base 1000, and the control valve 2000 comprises a valve core 2200 configured to be movably arranged to abut and disengage the air inlet port 1410. When the valve core 2200 abuts the air inlet port 1410, the valve core 2200 closes the air inlet port 1410. When the valve core 2200 disengages the air inlet port 1410, the valve core 2200 opens the air inlet port 1410. The valve core 2200 opening the air inlet port 1410 allows the air inlet port 1410 to be in communication with the air inlet channel 1100. The first gas valve 3000 is connected to the air inlet base 1000, and the first gas valve 3000 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 the second gas valve 4000 is in communication with a second outlet 1321 of the second gas outlet channel 1300.

[0057] By providing the first gas outlet channel 1200, the second gas outlet channel 1300 and the auxiliary channel 1400 in the air inlet base 1000, regular gas supply to the first gas valve 3000 can be achieved, and regular gas supply and wok-searing gas supply to the second gas valve 4000 can be achieved. 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 be mature products on the market, which has strong compatibility and is conducive to reducing structural complexity and cost.

[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 a split component connected together. Since the air inlet base 1000 is provided with multiple channels (the air inlet channel 1100, the first gas outlet channel 1200, the second gas outlet channel 1300 and the auxiliary channel 1400), the air inlet base 1000 is designed as an integrally formed structure, which is more conducive to preventing gas leakage and reducing the number of sealing points.

[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 regulate 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 regulate 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 in gas stoves can adopt plug valves. 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 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 second gas valve 4000. The auxiliary channel 1400 is 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. The valve core 2200 has two states, one of which is that the valve core 2200 abuts against the air inlet 1410, and the other of which 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 (i.e., closes the auxiliary channel 1400), and when the valve core 2200 is separated from the air inlet 1410, the valve core 2200 opens the air inlet 1410 (i.e., opens the auxiliary channel 1400). Since the second gas outlet channel 1300 is in communication with the air inlet channel 1100, 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 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 second gas outlet channel 1300 through the auxiliary channel 1400, so that the gas flow / pressure entering the second gas outlet channel 1300 becomes larger, and when the valve core 2200 abuts against the air inlet 1410, the gas cannot flow into the second gas outlet channel 1300 through the auxiliary channel 1400, so that the gas flow / pressure entering the second gas outlet channel 1300 becomes smaller, that is, when the valve core 2200 abuts against the air inlet 1410, the normal gas supply of the second gas valve 4000 can be realized, and when the valve core 2200 is separated from the air inlet 1410, the stir-frying gas supply of 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).

[0061] 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. The gas flow is as follows:

[0062] The first kind is to heat the cooker only through the first burner, the first burner is turned on, the gas enters the inside of the air inlet seat 1000 from the air inlet channel 1100 and flows into the first gas outlet channel 1200, the gas flows along the first gas outlet channel 1200 and passes through the first gas valve 3000, so that the normal gas supply of the first gas valve 3000 is realized, and the first gas valve 3000 can adjust the gas flow to the first burner, at this time the gas stove can realize the heating in the normal mode through the first burner.

[0063] The second, only through the second burner heating cookware and valve core 2200 abutment inlet 1410, open second gas valve 4000, gas from the gas inlet channel 1100 into the intake seat 1000 inside and from the intake seat 1000 inside 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 conventional gas supply to the second gas valve 4000, the second gas valve 4000 can adjust the flow of gas to the second burner, at this time the gas stove can be through the second burner to achieve the heating of the conventional mode.

[0064] The third, only through the second burner heating cookware and valve core 2200 away from the inlet 1410, open second gas valve 4000, gas from the gas inlet channel 1100 into the intake seat 1000 inside and from the intake seat 1000 inside into the second gas outlet channel 1300, and from the intake seat 1000 inside through the inlet 1410 into the auxiliary channel 1400 and then from the auxiliary channel 1400 into the second gas outlet channel 1300 (that is, 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 explosive stir-frying gas supply to the second gas valve 4000, the second gas valve 4000 can adjust the flow of gas to the second burner, at this time the gas stove can be through the second burner to achieve the heating of the explosive stir-frying mode.

[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 a simultaneous use state, the gas stove can be through the first burner and the second burner to achieve the heating of the conventional mode, or it can be through the first burner to achieve the heating of the conventional mode and through the second burner to achieve the heating of the explosive stir-frying mode.

[0066] 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 air inlet 1410 to realize the normal gas supply of the second gas valve 4000 or separates from the air inlet 1410 to realize the wok-fried gas supply of the second gas valve 4000, the gas supply adjustment is performed on the whole of the second gas valve 4000, that is, when the second gas valve 4000 is normally supplied with gas, the outer annular passage 4200 and the inner annular passage 4100 of the second gas valve 4000 can be normally supplied with gas, and when the second gas valve 4000 is wok-fried supplied with gas, the outer annular passage 4200 and the inner annular passage 4100 of the second gas valve 4000 can be wok-fried supplied with gas, so that the outer annular flame hole and the inner annular flame hole of the second burner can be simultaneously wok-fried heated or simultaneously normally heated, and the heating of the cooker is more uniform.

[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 the rational use of space and is more convenient for the air inlet connection of the air inlet channel 1100.

[0068] In combination Figures 4 to 15 As shown in some embodiments, the air inlet seat 1000 is provided with a containing cavity 1500, the valve core 2200 is movably arranged in the containing cavity 1500, the air inlet channel 1100 and the containing cavity 1500 are in communication, the first air outlet channel 1200 and the containing cavity 1500 are in communication, the second air outlet channel 1300 and the containing cavity 1500 are in communication, and the air inlet 1410 is in communication with the containing cavity 1500 when the valve core 2200 separates from the air inlet 1410.

[0069] It can be understood that the air inlet channel 1100 in communication with the containing cavity 1500 means that the gas enters the containing cavity 1500 from the air inlet channel 1100 (the gas flowing along the air inlet channel 1100 flows into the containing cavity 1500), the first air outlet channel 1200 in communication with the containing cavity 1500 means that the gas enters the first air outlet channel 1200 from the containing cavity 1500 (the gas flowing into the containing cavity 1500 continues to flow into the first air outlet channel 1200), the second air outlet channel 1300 in communication with the containing cavity 1500 means that the gas enters the second air outlet channel 1300 from the containing cavity 1500 (the gas flowing into the containing cavity 1500 continues to flow into the second air outlet channel 1300), and the air inlet 1410 in communication with the containing cavity 1500 means that the gas enters the auxiliary channel 1400 from the containing cavity 1500 (the gas flowing into the containing cavity 1500 continues to flow into the auxiliary channel 1400).

[0070] 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, the gas inlet passage 1100 and the auxiliary passage 1400).

The control valve 2000 is fixed to the gas inlet seat 1000 to cover the opening 1510, thereby sealing the accommodation cavity 1500.

[0071] With the arrangement of the accommodation cavity 1500, the gas flow is as follows:

[0072] First, only the first burner is used to heat the cooker, the first burner is turned on, the gas enters the accommodation cavity 1500 from the gas inlet passage 1100 and flows into the first gas outlet passage 1200 from the accommodation cavity 1500, 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, and the gas stove can heat in the normal mode through the first burner.

[0073] Second, only the second burner is used to heat the cooker and the valve core 2200 abuts against the gas inlet port 1410, the second gas valve 4000 is turned on, the gas enters the accommodation cavity 1500 from the gas inlet passage 1100 and flows into the second gas outlet passage 1300 from the accommodation cavity 1500, 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, the second gas valve 4000 can adjust the gas flow to the second burner, and the gas stove can heat in the normal mode through the second burner.

The first air intake channel 1110 forms an inlet 1111 of the air intake channel 1100, and the second air intake channel 1120 is connected to the accommodating cavity 1500. The first intake passage 1110 is located upstream of the second intake passage 1120. It can receive gas through the first intake passage 1110. For example, the first intake passage 1110 forms the inlet 1111 of the intake passage 1100. The gas source can be connected to the inlet 1111 of the intake passage 1100. After the gas enters the intake passage 1100, it flows through the first intake passage 1110 and the second intake passage 1120 in sequence. The intersection and connection between the first intake passage 1110 and the second intake passage 1120 makes it easier for the intake passage 1100 to receive gas.

[0076] Optionally, combined Figures 8 to 11 As shown, in some embodiments, the second air intake channel 1120 extends downward from the accommodating cavity 1500 (including but not limited to directly below and diagonally below), and the first air intake channel 1110 extends backward from the second air intake channel 1120 (including but not limited to directly behind and diagonally behind). The orientations in this document are based on the gas stove being in its installed and used state. With the user standing facing the gas stove, the side of the gas stove facing the user is front, the side away from the user is back, the side corresponding to the user's left hand is left, the side corresponding to the user's right hand is right, the side closest to the ground is bottom, and the side away from the ground is top. Since the first gas valve 3000 and the second gas valve 4000 need to be positioned at the front of the gas stove for easy user control, the gas inlet seat 1000 also needs to be positioned at the front to accommodate the first gas valve 3000 and the second gas valve 4000. Furthermore, since the gas inlet channel 1100 needs to be connected to the gas source, it is generally necessary to achieve the connection through a pipeline structure. Therefore, 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 backward from the second gas inlet channel 1120 to facilitate connection with the gas source. This arrangement helps to reduce the space occupied by the gas control device. For example, the first gas inlet channel 1110 and the second gas inlet channel 1120 are perpendicular.

[0077] Combination Figures 4 to 7 as well as Figures 12 to 15As shown, in some embodiments, the first gas outlet passage 1200 comprises a first upstream passage 1210 and a first downstream passage 1220, i.e. the first upstream passage 1210 is located upstream of the first downstream passage 1220, the first upstream passage 1210 is in communication with the accommodating cavity 1500, the first downstream passage 1220 is in communication with the first upstream passage 1210, and the first downstream passage 1220 is provided with a first outlet 1221, and the fuel gas flows through the first upstream passage 1210 and the first downstream passage 1220 in sequence; the second gas outlet passage 1300 comprises a second upstream passage 1310 and a second downstream passage 1320, i.e. the second upstream passage 1310 is located upstream of the second downstream passage 1320, the second upstream passage 1310 is in communication with the accommodating cavity 1500, the second downstream passage 1320 is in communication with the second upstream passage 1310, and the second downstream passage 1320 is provided with a second outlet 1321, and the fuel gas flows through the second upstream passage 1310 and the second downstream passage 1320 in sequence, and by so arranging, it is more convenient to arrange the first gas valve 3000 and the second gas valve 4000, and it is helpful to reduce the space occupied by the fuel gas control device.

[0078] Optionally, in combination with Figures 1 to 16 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, so as to correspond to the double-head stove design (double-head stove means having two burners) of the gas stove:

[0079] The included angle between the first upstream passage 1210 and the first downstream passage 1220 is a right angle, which helps the gas control device to reasonably use the space. For example, the first upstream passage 1210 extends from the containing cavity 1500 to 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 to the left rear. The included angle between the auxiliary passage 1400 and the second upstream passage 1310 is an acute angle or parallel, which helps the gas control device to reasonably use the space. For example, the auxiliary passage 1400 extends from the containing cavity 1500 to the lower front, avoiding the second gas inlet passage 1120, and the second upstream passage 1310 extends to the lower right, which facilitates the gas to be directed to the right. The included angle between the auxiliary passage 1400 and the second downstream passage 1320 is a right angle, which helps the gas control device to reasonably use the space. For example, the auxiliary passage 1400 extends from the containing cavity 1500 to the lower front, and the second downstream passage 1320 extends from the auxiliary passage 1400 to the right. The auxiliary passage 1400, the second upstream passage 1310, and the second downstream passage 1320 are coplanar, which helps the gas control device to reasonably use the space. The included angle between the auxiliary passage 1400 and the second gas inlet passage 1120 of the gas inlet passage 1100 is an acute angle, which helps the gas control device to reasonably use the space. By such arrangement, it is beneficial for the gas control device to reduce the occupation of the space volume, which is conducive to miniaturization design and more compact structure. The included angle means the smallest positive angle between two straight lines or extensions of two straight lines.

[0080] Optionally, in combination with Figure 17 As 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 (double-head stove means having two burners):

[0081] 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 utilize the space. For example, the first upstream passage 1210 extends obliquely from the containing cavity 1500 towards the lower right to guide the gas to the right, and the first downstream passage 1220 extends from the first upstream passage 1210 towards the right. The included angle between the auxiliary passage 1400 and the second upstream passage 1310 is an acute angle, which helps the gas control device to reasonably utilize the space. For example, the auxiliary passage 1400 extends obliquely from the containing cavity 1500 towards the lower front to avoid the second gas inlet passage 1120, and the second upstream passage 1310 extends towards the lower left to guide the gas to the left. The included angle between the auxiliary passage 1400 and the second gas inlet passage 1120 of the gas inlet passage 1100 is an acute angle, which helps the gas control device to reasonably utilize the space. For example, the auxiliary passage 1400 extends obliquely from the containing cavity 1500 towards the lower front, and the second gas inlet passage 1120 extends from the containing cavity 1500 towards the lower. By such arrangement, it is beneficial for the gas control device to reduce the occupation of the space volume, facilitate miniaturization design, and make the structure more compact.

[0082] In combination Figures 8 to 15 As shown, in some embodiments, the auxiliary passage 1400 protrudes into the containing cavity 1500, and the portion of the auxiliary passage 1400 protruding into the containing cavity 1500 is provided with the gas inlet 1410, that is, the periphery of the gas inlet 1410 is raised relative to the cavity wall of the containing cavity 1500, which is more convenient for the sealing cooperation between the valve core 2200 and the gas inlet 1410 when the valve core 2200 abuts against the gas inlet 1410, especially when the valve core 2200 abuts against the periphery of the gas inlet 1410 through the sealing gasket 2210, which is more beneficial for the deformation of the sealing gasket 2210 to form a better sealing effect.

[0083] In combination Figures 12 to 15 As shown, in some embodiments, the auxiliary passage 1400 intersects and communicates with the second gas outlet passage 1300, which is more convenient for the arrangement of the gas path and helps to reasonably utilize the space.

[0084] Optionally, when the second gas outlet passage 1300 includes the second upstream passage 1310 and the second downstream passage 1320 intersecting and communicating with each other, the second upstream passage 1310 communicates with the containing cavity 1500, the second downstream passage 1320 is provided with the second outlet 1321, the auxiliary passage 1400 communicates to the second downstream passage 1320, the gas entering the second upstream passage 1310 flows to the second downstream passage 1320, and the gas entering the auxiliary passage 1400 flows to the second downstream passage 1320 (the cross-sectional size of the second upstream passage 1310 can be set according to the firepower required for conventional heating).

[0085] 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 synchronously), and there is no need to set a hole structure 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, so that the number of sealing points can be reduced. 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.

[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, 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, there is no need to set a hole structure in other places to drill the first air inlet channel 1110, the first downstream channel 1220 and / or the second downstream channel 1320, so that the number of sealing points can be reduced.

[0087] 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.

[0088] In combination Figures 1 to 3As shown, the first gas valve 3000 comprises an inner ring channel 3100 and an outer ring channel 3200, the second gas valve 4000 comprises an inner ring channel 4100 and an 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), and the first direction surrounds the air inlet seat 1000. As shown in the figure, Figure 3 As shown, the first direction is counterclockwise 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, so that the first gas valve 3000 and the second gas valve 4000 have consistent structure or similar structure, 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 structure or similar structure, 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.

[0089] The second aspect of the present application discloses a gas stove, which combines Figures 1 to 17 As shown, the gas stove comprises the above-mentioned gas control device, and the gas stove of the embodiment is designed as a double-burner, 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 therefore at least has the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.
