[0046] In addition, in the present application, the description such as "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features.

When the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0047] The first aspect of the present application discloses a gas control device, which combines Figures 1 to 13 As shown in the drawings, in some embodiments, the gas control device comprises an air inlet seat 1000, a control valve 2000 and a first gas valve 3000. The air inlet seat 1000 is provided with an air inlet channel 1100 and a first air outlet channel 1200. The first air outlet channel 1200 is provided with an air inlet port 1211. The air inlet port 1211 is in communication with the air inlet channel 1100, that is, the first air outlet channel 1200 is in communication with the air inlet channel 1100 through the air inlet port 1211. The control valve 2000 is connected with the air inlet seat 1000. The control valve 2000 comprises a valve core 2200. The valve core 2200 is movably arranged so as to abut against or be separated from the air inlet port 1211. The valve core 2200 blocks part of the air inlet port 1211 when abutting against the air inlet port 1211. The first gas valve 3000 is connected with the air inlet seat 1000, and the first gas valve 3000 is in communication with an air outlet port 1221 of the first air outlet channel 1200.

[0048] The cooperation of the air inlet seat 1000 and the control valve 2000 can realize the switching of the normal gas supply and the wok-hei gas supply of the first gas valve 3000. The first gas valve 3000 can adopt the mature products on the market at present without structural improvement. The compatibility is strong, which is conducive to reducing the structural complexity and cost. Since the overall gas supply of the first gas valve 3000 can be controlled, when the wok-hei gas supply is performed on the first gas valve 3000, the outer ring and the inner ring of the corresponding burner can be simultaneously in the wok-hei state, and the heating of the cooker is more uniform.

[0049] Specifically, the gas inlet seat 1000 needs to be connected with a gas source, which can be a filling liquefied gas or a pipeline natural gas. The gas source is connected to the gas inlet channel 1100 of the gas inlet seat 1000, and the gas provided by the gas source enters the interior of the gas inlet seat 1000 through the gas inlet channel 1100, and then can enter the first gas outlet channel 1200 through the gas inlet port 1211 and flow along the first gas outlet channel 1200 to be discharged. The gas inlet seat 1000 can be an integrally formed structure or a split component connected together. Since the gas inlet seat 1000 is provided with several channels (the gas inlet channel 1100 and the first gas outlet channel 1200), it is more beneficial to prevent gas leakage and reduce the number of sealing points to design the gas inlet seat 1000 as an integrally formed structure.

[0050] The first gas valve 3000 is connected with the gas inlet seat 1000 and communicates with the gas outlet port 1221 of the first gas outlet channel 1200. The gas discharged through the first gas outlet channel 1200 can flow through the first gas valve 3000 through the gas outlet port 1221, and the first gas valve 3000 can adjust the flow of the gas flowing through. The type of the first gas valve 3000 is various, such as a plug valve, a ball valve, a butterfly valve, etc., which can be selected according to the actual situation. The commonly used plug valve can be used for a gas stove. The first gas valve 3000 and the gas inlet seat 1000 are split components connected and fixed by a connecting means, such as screw connection, welding, etc.

[0051] In the embodiment, the control valve 2000 is arranged, and the gas discharged through the first gas outlet channel 1200 needs to be controlled by the control valve 2000 to realize the switching between the normal gas supply and the stir-frying gas supply of the first gas valve 3000. The control valve 2000 comprises a valve core 2200, which is a movable component. The movement of the valve core 2200 has two states. In the first state, the valve core 2200 abuts against the gas inlet 1211. In the second state, the valve core 2200 is separated from the gas inlet 1211. When the valve core 2200 abuts against the gas inlet 1211, the valve core 2200 blocks part of the gas inlet 1211. When the valve core 2200 is separated from the gas inlet 1211, the gas inlet 1211 is completely opened (relative to the state that the valve core 2200 abuts against the gas inlet 1211). That is, when the valve core 2200 abuts against the gas inlet 1211, the opening degree of the gas inlet 1211 is relatively small, so that the gas flow rate / pressure entering the first gas outlet channel 1200 is small. When the valve core 2200 is separated from the gas inlet 1211, the opening degree of the gas inlet 1211 is relatively large, so that the gas flow rate / pressure entering the first gas outlet channel 1200 is large. In this way, when the valve core 2200 abuts against the gas inlet 1211, the normal gas supply of the first gas valve 3000 can be realized. When the valve core 2200 is separated from the gas inlet 1211, the stir-frying gas supply of the first gas valve 3000 can be realized (the firepower of the stir-frying gas supply is larger than that of the normal gas supply).

[0052] The gas control device is further described by taking a gas stove as an example. The gas stove comprises the gas control device and a first burner. The gas inlet channel 1100 of the gas inlet seat 1000 is connected to a gas source. The gas in the gas source enters the interior of the gas inlet seat 1000 through the gas inlet channel 1100, and then enters the first gas outlet channel 1200 through the gas inlet 1211 and flows along the first gas outlet channel 1200 to be discharged. The gas flowing along the first gas outlet channel 1200 can flow out through the gas outlet 1221 to flow through the first gas valve 3000, and the gas flow rate flowing to the first burner is controlled by the first gas valve 3000. The gas flow form is as follows:

[0053] Firstly, the valve core 2200 is separated from the gas inlet 1211, and the first gas valve 3000 is opened. The gas in the gas inlet channel 1100 enters the interior of the gas inlet seat 1000 and flows into the first gas outlet channel 1200 through the gas inlet 1211. The gas flows along the first gas outlet channel 1200 and flows out from the gas outlet 1221 to flow through the first gas valve 3000. In this way, the stir-frying gas supply of the first gas valve 3000 is realized. The first gas valve 3000 can adjust the gas flow rate flowing to the first burner. At this time, the gas stove can realize the heating in the stir-frying mode through the first burner.

[0054] Second, the valve core 2200 abuts the gas inlet 1211, and the first gas valve 3000 is opened. The gas enters the interior of the gas seat 1000 from the gas inlet channel 1100 and flows into the first gas outlet channel 1200 through the gas inlet 1211. The gas flows along the first gas outlet channel 1200 and flows out of the gas outlet 1221 to flow through the first gas valve 3000. In this way, the first gas valve 3000 is supplied with gas in a normal manner. The first gas valve 3000 can adjust the gas flow to the first burner, and the gas stove can heat in a normal mode through the first burner.

[0055] Generally, the first burner is provided with an outer ring fire hole and an inner ring fire hole, and the first gas valve 3000 has an outer ring channel 3200 and an inner ring channel 3100. The outer ring channel 3200 controls the gas supply of the outer ring fire hole, and the inner ring channel 3100 controls the gas supply of the inner ring fire hole. Whether the valve core 2200 abuts the gas inlet 1211 or separates from the gas inlet 1211, the gas supply of the first gas valve 3000 is adjusted as a whole. That is, when the first gas valve 3000 is supplied with gas in a normal manner, the outer ring channel 3200 and the inner ring channel 3100 of the first gas valve 3000 are supplied with gas in a normal manner. When the first gas valve 3000 is supplied with gas for stir-frying, the outer ring channel 3200 and the inner ring channel 3100 of the first gas valve 3000 are supplied with gas for stir-frying. In this way, the outer ring fire hole and the inner ring fire hole of the first burner can be heated simultaneously for stir-frying or simultaneously for normal heating, and the heating of the cooker is more uniform.

[0056] In combination Figures 6 to 13 As shown in FIG. 8, in some embodiments, the valve core 2200 abuts the periphery of the gas inlet 1211, and the valve core 2200 is provided with a communication channel 2210. The communication channel 2210 is adapted to communicate the gas inlet channel 1100 and the remaining part of the gas inlet 1211 when the valve core 2200 abuts the periphery of the gas inlet 1211. By abutting the periphery of the gas inlet 1211, the valve core 2200 is subjected to a more uniform force (reaction force applied by the periphery of the gas inlet 1211), which helps to improve the effect of the valve core 2200 on the part of the gas inlet 1211, avoid leakage, and ensure normal gas supply. Since the valve core 2200 is movable, the more uniform force on the valve core 2200 is more conducive to prolonging the service life of the control valve 2000.

[0057] When the valve core 2200 abuts the periphery of the gas inlet 1211, one end of the communication channel 2210 communicates with the remaining part of the gas inlet 1211, and the other end communicates with the gas inlet channel 1100 (the cross-sectional size of the communication channel 2210 can be set according to the heat required for normal heating). In combination Figures 6 to 13As 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 1211, the communication passage 2210 and the remaining part of the air inlet 1211 are communicated, that is, the communication passage 2210 is communicated with the first air outlet passage 1200, 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 first air outlet passage 1200 are communicated. When the valve core 2200 abuts against the periphery of the air inlet 1211, the gas from the air inlet passage 1100 enters the inside of the air seat 1000 and flows through the communication passage 2210, the remaining part of the air inlet 1211 and then flows into the first air outlet passage 1200.

[0058] Optionally, the valve core 2200 has a sealing pad 2220, and the valve core 2200 abuts against the periphery of the air inlet 1211 through the sealing pad 2220. The sealing pad 2220 is adapted to be elastically deformed, so that a better sealing effect can be achieved. When the valve core 2200 has the sealing pad 2220, the sealing pad 2220 has a ring structure and surrounds one end of the communication passage 2210.

[0059] In combination Figures 6 to 13 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 two are not in the same straight line, the same below). The communication passage 2210 is adapted to be communicated with the air inlet passage 1100 through the first communication passage 2211, and the communication passage 2210 is adapted to be communicated with the remaining part of the air inlet 1211 through the second communication passage 2212. The first communication passage 2211 and the second communication passage 2212 are intersected and communicated, which is more convenient for the arrangement and cooperation of structures. The so-called intersected and communicated means that the two are not straight but form an included angle.

[0060] For example, the valve core 2200 is designed to be reciprocally movable along its axial direction, the air inlet 1211 is located in the axial direction of the valve core 2200, the valve core 2200 moves towards the air inlet 1211 so as to abut against the air inlet 1211, and moves away from the air inlet 1211 so as to be separated from the air inlet 1211, on 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, the second communication passage 2212 realizes communication with the remaining part of the air inlet 1211, and the gas flows through the first communication passage 2211 and the second communication passage 2212 in turn so as to enter the first gas outlet passage 1200 through the air inlet 1211, in this way, the valve core 2200 does not affect the plugging of the air inlet 1211, and the communication between the air inlet passage 1100 and the first gas outlet passage 1200 is realized, 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.

[0061] In combination Figures 3 to 14 As shown in the drawings, in some embodiments, the air inlet seat 1000 is provided with a receiving cavity 1400, the air inlet passage 1100 communicates with the receiving cavity 1400, the air inlet 1211 communicates with the receiving cavity 1400, that is, the first gas outlet passage 1200 communicates with the receiving cavity 1400 through the air inlet 1211, and the valve core 2200 is movably arranged in the receiving cavity 1400.

[0062] It can be understood that the communication between the air inlet passage 1100 and the receiving cavity 1400 means that the gas flows from the air inlet passage 1100 into the receiving cavity 1400 (the gas flowing along the air inlet passage 1100 flows into the receiving cavity 1400), and the communication between the air inlet 1211 and the receiving cavity 1400 means that the gas flows from the receiving cavity 1400 into the first gas outlet passage 1200 (the gas flowing into the receiving cavity 1400 continues to flow into the first gas outlet passage 1200).

[0063] The arrangement of the receiving cavity 1400 facilitates the movement of the valve core 2200 and the communication between the passages (the air inlet passage 1100 and the first gas outlet passage 1200). For example, the receiving cavity 1400 has an opening 1410, the control valve 2000 is installed to the air inlet seat 1000 in alignment with the opening 1410, the valve core 2200 is inserted into the receiving cavity 1400 through the opening 1410, and the valve core 2200 can move in the receiving cavity 1400, the control valve 2000 is connected and fixed to the air inlet seat 1000 so as to cover the opening 1410, thereby sealing the receiving cavity 1400.

[0064] On the premise of arranging the receiving cavity 1400, the gas flow is as follows:

[0065] The first, the valve core 2200 is separated from the air inlet 1211, the first gas valve 3000 is opened, the gas enters the containing cavity 1400 from the air inlet 1211 along the first gas valve 3000, so as to realize the explosive supply of 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 realize the heating of the explosive mode through the first burner.

[0066] The second, the valve core 2200 abuts against the air inlet 1211, the first gas valve 3000 is opened, the gas enters the containing cavity 1400 from the air inlet 1211 along the first gas valve 3000, so as to realize the normal supply of 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 realize the heating of the normal mode through the first burner.

[0067] In combination Figures 6 to 13 As shown in the drawings, in some embodiments, the first gas outlet channel 1200 protrudes into the containing cavity 1400, and the part of the first gas outlet channel 1200 protruding into the containing cavity 1400 is provided with the air inlet 1211, that is, the periphery of the air inlet 1211 is raised relative to the cavity wall of the containing cavity 1400, which is more convenient for the sealing cooperation between the valve core 2200 and the air inlet 1211 when the valve core 2200 abuts against the air inlet 1211, especially when the valve core 2200 abuts against the periphery of the air inlet 1211 through the sealing gasket 2220, which is more conducive to the deformation of the sealing gasket 2220, and better sealing effect is formed.

[0068] In combination Figures 6 to 13As shown, in some embodiments, the first gas inlet channel 1110 and the second gas inlet channel 1120 are intersectingly communicated, and the second gas inlet channel 1120 is communicated with the accommodating cavity 1400. 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 is formed with an inlet 1111 of the gas inlet channel 1100, and a gas source can be connected to the inlet 1111 of the gas inlet channel 1100. After the gas enters the gas inlet channel 1100, it flows through the first gas inlet channel 1110 and the second gas inlet channel 1120 in turn, and the intersection communication of the first gas inlet channel 1110 and the second gas inlet channel 1120 is more convenient for the gas inlet channel 1100 to receive the gas.

[0069] In combination Figures 6 to 13 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 located upstream of the first downstream channel 1220. The first upstream channel 1210 is provided with a gas inlet 1211, the first downstream channel 1220 is intersectingly communicated with the first upstream channel 1210, and the first downstream channel 1220 is provided with a gas outlet 1221. The gas flows through the first upstream channel 1210 and the first downstream channel 1220 in turn, and the arrangement of the first gas valve 3000 is more convenient, which helps to reduce the space occupied by the gas control device.

[0070] Since the second gas inlet channel 1120 and the first upstream channel 1210 are respectively communicated with the accommodating cavity 1400, when the gas inlet seat 1000 is machined, the second gas inlet channel 1120 and / or the first upstream channel 1210 can be drilled through the accommodating cavity 1400 (when the first upstream channel 1210 is drilled, the gas inlet 1211 is formed at the same time), without the need to set a hole structure elsewhere to drill the second gas inlet channel 1120 and / or the first upstream channel 1210, so as to reduce the number of sealing points. For example, along the extension direction of the second gas inlet channel 1120, the second gas 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.

[0071] Similarly, since the first gas inlet channel 1110 has the inlet 1111, the first downstream channel 1220 has the gas outlet 1221, the first gas inlet channel 1110 is drilled to correspondingly form the inlet 1111, the first downstream channel 1220 is drilled to correspondingly form the gas outlet 1221, and since the inlet 1111 is used to receive gas, the gas outlet 1221 is in communication with the first gas valve 3000 to form a seal, there is no need to set a hole structure elsewhere to drill the first gas inlet channel 1110 and / or the first downstream channel 1220, so as to reduce the number of sealing points.

[0072] 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 achieve the opening and closing of the gas inlet 1211.

[0073] In combination Figures 6 to 13 As shown, in some embodiments, the gas inlet seat 1000 is provided with a second gas outlet channel 1300, the second gas outlet channel 1300 is adapted to be in communication with the gas inlet channel 1100, and the second gas outlet channel 1300 is blocked. Specifically, the gas inlet seat 1000 has the gas inlet channel 1100, the first gas outlet channel 1200 and the second gas outlet channel 1300 when it is produced, the second gas outlet channel 1300 can be provided through or not, in the case of through, and when applied to a single-head stove design, the second gas outlet channel 1300 needs to be blocked, in the case of not through, and when applied to a double-head stove design, the second gas outlet channel 1300 needs to be opened, which will be described below by way of example of the second gas outlet channel 1300 being provided through. When the gas inlet seat 1000 is applied to a single-head stove design of the gas stove (single-head stove means having one burner), the second gas outlet channel 1300 needs to be blocked, such as being screwed to block the second gas outlet channel 1300, and gas cannot be discharged through the second gas outlet channel 1300. When the gas inlet seat 1000 is applied to a double-head stove design of the gas stove (double-head stove means having two burners), the first gas outlet channel 1200 corresponds to the first gas valve 3000, the first gas valve 3000 corresponds to the first burner, the second gas outlet channel 1300 corresponds to the second gas valve, and the second gas valve corresponds to the second burner, and gas can be discharged from the first gas outlet channel 1200 and the second gas outlet channel 1300. That is, after the gas inlet seat 1000 is produced, it can be applied to a single-head stove design of the gas stove (the second gas outlet channel 1300 needs to be blocked) or a double-head stove design of the gas stove (the second gas outlet channel 1300 does not need to be blocked), without the need to produce two specifications of the gas inlet seat 1000, improving the universality of the gas inlet seat 1000 and helping to reduce costs.

[0074] The second aspect of the present application discloses a gas stove, in combination Figures 1 to 14As shown, the gas stove comprises the above-mentioned gas control device, wherein the first gas valve 3000 corresponds to the first burner and controls the gas supply of the first burner. The switching between the normal gas supply and the explosive frying gas supply of the first gas valve 3000 can be realized by the cooperation of the air inlet seat 1000 and the control valve 2000, without the need to improve the structure of the first gas valve 3000. The first gas valve 3000 can adopt the mature products on the market at present, and has strong compatibility, which is conducive to reducing the structural complexity and cost. Since the overall gas supply of the first gas valve 3000 can be controlled, when the explosive frying gas supply of the first gas valve 3000 is realized, the outer ring and the inner ring of the corresponding burner can be simultaneously in the explosive frying state, and the heating of the cookware is more uniform. 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.

[0075] The above-mentioned is only the preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields based on the concept of the present application and the content of the specification and drawings are included in the patent protection scope of the present application.
