Description

Technical Field

[0001] This application relates to the field of gas stove technology, and in particular to a gas control device and a gas stove. Background Technology

[0002] Existing gas stoves are equipped with regular mode and stir-fry mode to meet diverse cooking environments. The heat of the stir-fry mode is much greater than that of the regular mode. Currently, most stir-fry modes require modification of the gas valve, which makes the structure of the gas valve more complex and can only create a stir-fry effect on the outer or inner ring of the burner, resulting in uneven temperature of the cookware.

[0069] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0070] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0071] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0073] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0074] The first aspect of this application discloses a gas control device, combined with Figures 1 to 35 As shown, in some embodiments, the gas control device includes an inlet seat 1000, a control valve 2000, an adjusting member 5000, and a first gas valve 3000. The inlet seat 1000 is provided with an inlet channel 1100, a first outlet channel 1200, and an auxiliary channel 1400. The first outlet channel 1200 is connected to the inlet channel 1100, and the auxiliary channel 1400 is connected to the first outlet channel 1200 so that gas can flow from the auxiliary channel 1400 to the first outlet channel 1200. The auxiliary channel 1400 is provided with an inlet port 1410. The control valve 2000 is connected to the inlet seat 1000. The control valve 2000 includes a valve core 2200, which is movably configured to abut and disengage from the air inlet 1410. The valve core 2200 is adapted to close the air inlet 1410 when abutting it, and to open the air inlet 1410 when disengaging it, thereby connecting the air inlet 1410 with the air intake passage 1100. The adjusting member 5000 is connected to the air intake seat 1000 and is adapted to adjust the opening of the first air outlet passage 1200. The first gas valve 3000 is connected to the air intake seat 1000 and communicates with the first outlet 1233 of the first air outlet passage 1200.

[0075] By setting a first gas outlet channel 1200 and an auxiliary channel 1400 in the air inlet seat 1000, both regular gas supply and high-heat gas supply to the first gas valve 3000 can be achieved without structural modifications to the first gas valve 3000. The first gas valve 3000 can use currently available mature products with strong compatibility, which helps to reduce structural complexity and cost. The opening of the first gas outlet channel 1200 can also be adjusted by adjusting the adjusting component 5000, thus adapting to different gas sources and load sizes.

[0076] Specifically, the air inlet 1000 needs to be connected to a gas source, which can be bottled liquefied petroleum gas (LPG) or piped natural gas. The gas source is connected to the air inlet channel 1100 of the air inlet 1000. The gas supplied by the gas source enters the interior of the air inlet 1000 through the air inlet channel 1100 and can then be discharged through the first air outlet channel 1200. The air inlet 1000 can be a one-piece molded structure or a combination of separate components. Since the air inlet 1000 has multiple channels (air inlet channel 1100, first air outlet channel 1200, and auxiliary channel 1400), designing the air inlet 1000 as a one-piece molded structure is more conducive to preventing gas leakage and reducing the number of sealing points.

[0077] The first gas valve 3000 is connected to the air inlet seat 1000 and communicates with the first outlet 1233 of the first gas outlet channel 1200. Gas entering the air inlet seat 1000 through the air inlet channel 1100 can be discharged through the first gas outlet channel 1200 and flow through the first gas valve 3000. The first gas valve 3000 can regulate the flow rate of the gas. The first gas valve 3000 can be of various types, such as a plug valve, ball valve, or butterfly valve, and can be selected according to the actual situation. A plug valve is commonly used in gas stoves. The first gas valve 3000 and the air inlet seat 1000 are separate components connected and fixed by means such as screws or welding.

[0078] In this embodiment, the air intake seat 1000 is provided with an auxiliary channel 1400. The auxiliary channel 1400 needs to cooperate with the control valve 2000 to switch between normal gas supply and stir-fry gas supply to the first gas valve 3000. The auxiliary channel 1400 is connected to the first gas outlet channel 1200 so that gas can flow from the auxiliary channel 1400 to the first gas outlet channel 1200. The auxiliary channel 1400 is provided with an air inlet 1410. The control valve 2000 includes a valve core 2200, which is a movable part. 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 disengages 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). When the valve core 2200 disengages from the air inlet 1410, the valve core 2200 opens the air inlet 1410 (i.e., opens the auxiliary channel 1400). Since the first outlet channel 1200 is connected to the air inlet channel 1100, the gas can be discharged through the first outlet channel 1200 regardless of whether the valve core 2200 abuts against or disengages from the air inlet 1410. However, when the valve core 2200 disengages from the air inlet 1410, the gas can still flow into the first outlet channel 1200 through the auxiliary channel 1400. The gas passage 1200 increases the gas flow rate / pressure entering the first gas outlet passage 1200. When the valve core 2200 abuts against the air inlet 1410, the gas cannot flow into the first gas outlet passage 1200 through the auxiliary passage 1400, thus reducing the gas flow rate / pressure entering the first gas outlet passage 1200. In other words, when the valve core 2200 abuts against the air inlet 1410, it can achieve normal gas supply to the first gas valve 3000, and when the valve core 2200 disengages from the air inlet 1410, it can achieve high-heat gas supply to the first gas valve 3000 (the heat of high-heat gas supply is greater than that of normal gas supply).

[0079] Taking a gas stove as an example, the gas control device will be further explained. The gas stove includes a gas control device and a first burner. The air inlet channel 1100 of the air inlet seat 1000 is connected to the gas source, and the first gas valve 3000 controls the gas flow to the first burner. The gas flow pattern is as follows:

[0080] In the first configuration, the valve core 2200 abuts against the air inlet 1410, opening the first gas valve 3000. Gas enters the interior of the air inlet seat 1000 from the air inlet channel 1100 and flows into the first air outlet channel 1200 from the interior of the air inlet seat 1000. The gas flows along the first air outlet channel 1200 and through the first gas valve 3000, thus achieving normal gas supply to the first gas valve 3000. The first gas valve 3000 can regulate the gas flow to the first burner. At this time, the gas stove can achieve normal heating through the first burner.

[0081] In the second scenario, the valve core 2200 disengages from the air inlet 1410, opening the first gas valve 3000. Gas enters the interior of the air inlet seat 1000 through the air inlet channel 1100 and flows into the first air outlet channel 1200 from inside the air inlet seat 1000. It then flows from inside the air inlet seat 1000 through the air inlet 1410 into the auxiliary channel 1400 and then into the first air outlet channel 1200 (i.e., compared to the case where the valve core 2200 is in contact with the air inlet 1410, an additional path is added for gas to flow into the first air outlet channel 1200 through the auxiliary channel 1400). This achieves gas supply for stir-frying using the first gas valve 3000. The first gas valve 3000 can regulate the gas flow to the first burner, allowing the gas stove to achieve stir-frying mode heating through the first burner.

[0082] Generally, the first burner is equipped with inner and outer ring flame holes, and the first gas valve 3000 has an inner ring channel 3100 and an outer ring channel 3200. The inner ring channel 3100 controls the gas supply to the inner ring flame holes, and the outer ring channel 3200 controls the gas supply to the outer ring flame holes. Whether the valve core 2200 is in contact with the air inlet 1410 to provide normal gas supply to the first gas valve 3000 or disconnected from the air inlet 1410 to provide high-heat gas supply to the first gas valve 3000, it is a function of the entire first gas valve 3000. The gas supply is adjusted so that when the first gas valve 3000 is supplied with gas normally, the outer ring channel 3200 and the inner ring channel 3100 of the first gas valve 3000 can be supplied with gas normally, and 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 can be supplied with gas for stir-frying at the same time, and the cookware can be heated more evenly.

[0083] It is understandable that different regions have different gas source types and load sizes. To adapt to more usage scenarios, this embodiment also includes an adjusting component 5000. The adjusting component 5000 is connected to the air inlet seat 1000 and is used to adjust the opening of the first air outlet channel 1200. Changing the opening size can correspondingly change the gas flow rate / pressure (it can achieve the corresponding change for both regular gas supply to the first gas valve 3000 and gas supply for stir-frying), thus adapting to more usage scenarios. It is worth noting that the adjusting component 5000 is generally not for users to adjust themselves, but is adjusted by professionals. After adjustment, without changing the usage scenario / gas source, it is usually not necessary to adjust the adjusting component 5000 again. Of course, whether to adjust it can be determined by professionals.

[0084] Combination Figures 11 to 17 as well as Figures 29 to 33As shown, in some embodiments, the first gas outlet channel 1200 includes an adjustment channel 1220 and a first downstream channel 1230. The first downstream channel 1230 is located downstream of the adjustment channel 1220. An adjustment member 5000 is disposed in the adjustment channel 1220 to adjust the opening of the first gas outlet channel 1200. An auxiliary channel 1400 is connected to the first downstream channel 1230. With this arrangement, the gas entering the adjustment channel 1220 flows to the first downstream channel 1230, and the gas entering the auxiliary channel 1400 flows to the first downstream channel 1230, reducing the impact of the adjustment member 5000 on the gas supply for stir-frying and making it more conducive to stir-frying heating.

[0085] Optionally, in some embodiments, the first air outlet passage 1200 includes an adjustment passage 1220, and the adjustment member 5000 is rotatably disposed in the adjustment passage 1220 to adjust the opening of the first air outlet passage 1200. The adjustment of the opening of the first air outlet passage 1200 by the adjustment member 5000 through rotation helps improve reliability and save space. Since the adjustment member 5000 is disposed in the adjustment passage 1220, it is protected by the air inlet seat 1000, preventing accidental rotation. For example, the adjusting component 5000 is screwed to the adjusting channel 1220. The adjusting component 5000 is provided with external threads, and the adjusting channel 1220 is provided with internal threads. The engagement of the external and internal threads enables the adjusting component 5000 to be screwed to the adjusting channel 1220. In this way, the adjusting component 5000 can be connected to the adjusting channel 1220 and can also rotate relative to the adjusting channel 1220 to adjust the opening of the first air outlet channel 1200. The screwed connection makes it difficult for the adjusting component 5000 to rotate under accidental force, ensuring the stability of the opening of the first air outlet channel 1200.

[0086] Combination Figures 11 to 17 as well as Figure 33 As shown, in some embodiments, the adjustment channel 1220 has an exposed opening 1224 on the outer surface of the air intake seat 1000. The adjustment member 5000 is adapted to pass through the exposed opening 1224 and be rotatably disposed in the adjustment channel 1220. The exposed opening 1224 facilitates the operation of the adjustment member 5000 to adjust the opening of the first air outlet channel 1200 without disassembling the air intake seat 1000, thus laying the foundation for the integral molding of the air intake seat 1000. It is understood that when the adjustment member 5000 is installed into the adjustment channel 1220 through the exposed opening 1224, a sealing ring 5200 needs to be provided between the adjustment member 5000 and the adjustment channel 1220 for sealing. For example, the sealing ring 5200 is sleeved on the adjustment member 5000, and a seal is formed between the adjustment member 5000 and the adjustment channel 1220 after the adjustment member 5000 is installed.

[0087] Optionally, combined Figures 1 to 17As shown, the exposed port 1224 is located on the side of the intake seat 1000. "Side" means that when the operator needs to adjust the adjusting component 5000, they need to operate it in a roughly lateral direction. For example, if the exposed port 1224 is located on the right side of the intake seat 1000, the operator needs to operate it roughly from right to left. However, this method is relatively easy to be obstructed by other components. For example, if the first gas valve 3000 is located on the right side of the intake seat 1000, and the exposed port 1224 is located on the right side of the intake seat 1000, then the first gas valve 3000 needs to be disassembled before operating the adjusting component 5000.

[0088] Optionally, combined Figures 18 to 33 As shown, the exposed port 1224 is located on the top surface of the air intake seat 1000. The so-called top surface means that when the operator rotates the adjusting component 5000, the operator needs to operate the adjusting component 5000 in a roughly vertical direction. For example, if the exposed port 1224 is located on the top surface of the air intake seat 1000, the operator needs to operate it roughly in a top-down direction. This method is relatively less likely to be blocked by other components. For example, regardless of whether the first gas valve 3000 is located on the left or right side of the air intake seat 1000, if the exposed port 1224 is located on the top surface of the air intake seat 1000, the first gas valve 3000 does not need to be disassembled before operating the adjusting component 5000.

[0089] It is understood that the orientation in this article is based on the gas stove being installed and in use. When the user stands facing the gas stove, the side of the gas stove facing the user is the front, the side away from the user is the back, the side corresponding to the user's left hand is the left, the side corresponding to the user's right hand is the right, the side closer to the ground is the bottom, and the side away from the ground is the top.

[0090] Adjusting the opening of the first air outlet channel 1200 by adjusting component 5000 is achieved in the following manner, combined with... Figures 11 to 17 as well as Figures 29 to 33 As shown, in some embodiments, the regulating channel 1220 includes an upstream section 1221 and a downstream section 1222. The gas is adapted to flow sequentially through the upstream section 1221 and the downstream section 1222. The flow cross-section of the upstream section 1221 is larger than that of the downstream section 1222. A stepped surface 1223 is provided between the upstream section 1221 and the downstream section 1222. The regulating member 5000 is rotatably disposed in the upstream section 1221. The regulating member 5000 is adapted to adjust the distance between itself and the stepped surface 1223 when rotating, so as to adjust the opening of the first gas outlet channel 1200.

[0091] When the adjusting member 5000 is rotated, it can move either towards or away from the step surface 1223. For example, if the adjusting member 5000 is screwed onto the upstream section 1221 of the adjusting channel, when rotating it forward, it moves towards the step surface 1223 and gradually approaches the downstream section 1222 of the adjusting channel; when rotating it in the reverse direction, it moves away from the step surface 1223 and gradually moves away from the downstream section 1222. Moving the adjusting member 5000 towards the step surface 1223 reduces the distance between it and the step surface 1223, thus decreasing the opening of the first air outlet channel 1200. Conversely, moving the adjusting member 5000 away from the step surface 1223 increases the distance between it and the step surface 1223, thus increasing the opening of the first air outlet channel 1200. It is understandable that when the gas enters the regulating channel 1220, it flows sequentially through the upstream section 1221 and the downstream section 1222 of the regulating channel. Since the regulating component 5000 needs to be rotatably located in the upstream section 1221 of the regulating channel, there can be a gap between the regulating component 5000 and the upstream section 1221 of the regulating channel, and the gas can flow through this gap to the downstream section 1222 of the regulating channel.

[0092] Optionally, combined Figures 11 to 17 as well as Figures 29 to 35 As shown, in some embodiments, the regulating member 5000 is provided with a connecting channel 5100. The gas flowing into the upstream section 1221 of the regulating channel is adapted to flow into the downstream section 1222 of the regulating channel through the gap between the upstream section 1221 and the regulating member 5000, and is also adapted to flow into the downstream section 1222 of the regulating channel through the connecting channel 5100. That is, the gas entering the upstream section 1221 of the regulating channel is divided into two streams. One stream of gas flows along the gap between the upstream section 1221 and the regulating member 5000 and flows into the downstream section 1222 of the regulating channel, while the other stream of gas flows along the connecting channel 5100 and flows into the downstream section 1222 of the regulating channel. This arrangement helps to improve the regulation effect on the opening of the first gas outlet channel 1200.

[0093] Combination Figures 11 to 17 as well as Figures 29 to 35As shown, in some embodiments, the first gas outlet passage 1200 further includes a first upstream passage 1210 located upstream of the regulating passage 1220. The inlet end 5110 of the connecting passage 5100 is adapted to be located in the extension direction of the first upstream passage 1210 when the regulating member 5000 rotates at a preset angle. Gas flows into the first upstream passage 1210 first and then into the regulating passage 1220. By adapting the inlet end 5110 of the connecting passage 5100 to be located in the extension direction of the first upstream passage 1210 when the regulating member 5000 rotates at a preset angle, the amount of gas flowing into the connecting passage 5100 is maximized when the inlet end 5110 of the connecting passage 5100 is directly opposite the extension direction of the first upstream passage 1210, and minimized when the inlet end 5110 of the connecting passage 5100 is completely offset from the extension direction of the first upstream passage 1210. This facilitates increasing the adjustment range of the opening of the first gas outlet passage 1200.

[0094] Combination Figures 6 to 17 as well as Figures 24 to 33 As shown, in some embodiments, the air intake seat 1000 is provided with a receiving cavity 1500, the valve core 2200 is movably disposed in the receiving cavity 1500, the air intake channel 1100 is connected to the receiving cavity 1500, the first air outlet channel 1200 is connected to the receiving cavity 1500, and the air inlet 1410 is connected to the receiving cavity 1500 when the valve core 2200 is disengaged from the air inlet 1410.

[0095] It is understandable that the connection between the intake passage 1100 and the accommodating cavity 1500 means that the gas flows from the intake passage 1100 into the accommodating cavity 1500 (the gas flowing along the intake passage 1100 flows into the accommodating cavity 1500), the connection between the first exhaust passage 1200 and the accommodating cavity 1500 means that the gas flows from the accommodating cavity 1500 into the first exhaust passage 1200 (the gas flowing into the accommodating cavity 1500 continues to flow into the first exhaust passage 1200), and the connection between the intake port 1410 and the accommodating cavity 1500 means that the gas flows from the accommodating cavity 1500 into the auxiliary passage 1400 (the gas flowing into the accommodating cavity 1500 continues to flow into the auxiliary passage 1400).

[0096] The arrangement of the accommodating cavity 1500 facilitates the movement of the valve core 2200 and also establishes the connection between the channels (intake channel 1100 and the first outlet channel 1200, and intake channel 1100 and auxiliary channel 1400). For example, the accommodating cavity 1500 has an opening 1510. The control valve 2000 is aligned with the opening 1510 and installed on the intake seat 1000. The valve core 2200 passes through the opening 1510 and is inserted into the accommodating cavity 1500, allowing the valve core 2200 to move within the accommodating cavity 1500. The control valve 2000 is connected and fixed to the intake seat 1000, thus covering the opening 1510 and sealing the accommodating cavity 1500.

[0097] Assuming a 1500mm accommodating cavity, the gas flow pattern is as follows:

[0098] In the first configuration, the valve core 2200 abuts against the air inlet 1410, opening the first gas valve 3000. Gas enters the accommodating cavity 1500 from the air inlet channel 1100 and flows from the accommodating cavity 1500 into the first air outlet channel 1200. The gas flows along the first air outlet channel 1200 and through the first gas valve 3000, thus achieving normal gas supply to the first gas valve 3000. The first gas valve 3000 can regulate the gas flow to the first burner. At this time, the gas stove can achieve normal heating through the first burner.

[0099] In the second scenario, the valve core 2200 disengages from the air inlet 1410, opening the first gas valve 3000. Gas enters the accommodating cavity 1500 from the air inlet channel 1100 and flows from the accommodating cavity 1500 into the first gas outlet channel 1200. Gas then flows from the accommodating cavity 1500 through the air inlet 1410 into the auxiliary channel 1400 and then from the auxiliary channel 1400 into the first gas outlet channel 1200 (i.e., compared to the case where the valve core 2200 is in contact with the air inlet 1410, an additional path is added for gas to flow from the auxiliary channel 1400 into the first gas outlet channel 1200). This achieves gas supply for stir-frying using the first gas valve 3000. The first gas valve 3000 can regulate the gas flow to the first burner, allowing the gas stove to achieve stir-frying mode heating through the first burner.

[0100] Combination Figures 3 to 10 as well as Figures 20 to 28 As shown, in some embodiments, the air intake channel 1100 includes a first air intake channel 1110 and a second air intake channel 1120. The first air intake channel 1110 and the second air intake channel 1120 are intersecting and connected (intersecting means that the two intersecting channels are not on the same straight line, the same below). 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.

[0101] Combination Figures 11 to 17As shown, in some embodiments, the first gas outlet channel 1200 includes a first upstream channel 1210, an adjustment channel 1220, and a first downstream channel 1230 that are sequentially intersecting and connected. The first upstream channel 1210 is located upstream of the adjustment channel 1220 and is connected to the accommodating cavity 1500. The adjustment member 5000 is rotatably disposed in the adjustment channel 1220 to adjust the opening of the first gas outlet channel 1200. The first downstream channel 1230 is located downstream of the adjustment channel 1220 and is provided with a first outlet 1233. Gas flows sequentially through the first upstream channel 1210, the adjustment channel 1220, and the first downstream channel 1230. This arrangement makes it easier to arrange the first gas valve 3000 and helps to reduce the space occupied by the gas control device.

[0102] Combination Figures 29 to 33 As shown, in some embodiments, the first downstream channel 1230 includes an upstream section 1231 and a downstream section 1232 of the first downstream channel that are intersecting and connected. The upstream section 1231 of the first downstream channel is intersecting and connected with the regulating channel 1220. The downstream section 1232 of the first downstream channel is provided with a first outlet 1233. By setting the upstream section 1231 and the downstream section 1232 of the first downstream channel, the gas path layout is further optimized.

[0103] Combination Figure 7 , Figure 8 , Figure 25 and Figure 26 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 an 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 makes it easier for the valve core 2200 to abut against the air inlet 1410 and to seal against the air inlet 1410. In particular, when the valve core 2200 abuts against the periphery of the air inlet 1410 through the sealing gasket 2210, it is more conducive to the deformation of the sealing gasket 2210 and forms a better sealing effect.

[0104] Since the second air intake channel 1120, the first upstream channel 1210, and the auxiliary channel 1400 are respectively connected to the accommodating cavity 1500, when machining the air intake seat 1000, the second air intake channel 1120, the first upstream channel 1210, and the auxiliary channel 1400 can be drilled through the accommodating cavity 1500 (the air intake port 1410 can be formed simultaneously when the auxiliary channel 1400 is drilled), there is no need to set hole structures elsewhere to drill the second air intake channel 1120, the first upstream channel 1210, and / or the auxiliary channel 1400, thus reducing the number of sealing points. For example, along the extension direction of the second intake passage 1120, the second intake passage 1120 may be exposed at the opening 1510 of the accommodating cavity 1500, and / or along the extension direction of the first upstream passage 1210, the first upstream passage 1210 may be exposed at the opening 1510 of the accommodating cavity 1500, and / or along the extension direction of the auxiliary passage 1400, the auxiliary passage 1400 may be exposed at the opening 1510 of the accommodating cavity 1500.

[0105] Similarly, since the first intake channel 1110 has an inlet 1111 and the first downstream channel 1230 has a first outlet 1233, drilling through the first intake channel 1110 will form the corresponding inlet 1111, and drilling through the first downstream channel 1230 will form the corresponding outlet 1233. Since the inlet 1111 is used to receive gas, and the first outlet 1233 is connected to the first gas valve 3000 to form a seal, there is no need to set up a hole structure elsewhere to drill through the first intake channel 1110 and / or the first downstream channel 1230, thus reducing the number of sealing points.

[0106] When the first downstream channel 1230 includes the upstream section 1231 and the downstream section 1232 of the first downstream channel, the first outlet 1233 can be formed when drilling out of the downstream section 1232 of the first downstream channel, while when drilling out of the upstream section 1231 of the first downstream channel, the formed hole needs to be sealed, for example, by tightening the seal with screws.

[0107] 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 and thus realize the opening and closing of the air inlet 1410.

[0108] Combination Figure 5 , Figure 14 , Figure 15 , Figure 22 , Figure 31 and Figure 32As shown, in some embodiments, the air intake seat 1000 is further provided with a second air outlet channel 1300, which is adapted to communicate with the air intake channel 1100, and the second air outlet channel 1300 is blocked. Specifically, when the air intake seat 1000 is manufactured, it has an air intake channel 1100, a first air outlet channel 1200, a second air outlet channel 1300, and an auxiliary channel 1400. The second air outlet channel 1300 can be configured to be continuous or not continuous. When it is configured to be continuous and applied to a single-burner stove design, the second air outlet channel 1300 needs to be blocked. When it is configured to be not continuous and applied to a double-burner stove design, the second air outlet channel 1300 needs to be open. The following description uses the configuration of the second air outlet channel 1300 being continuous as an example. When the air intake 1000 is applied to a gas stove with a single-burner design (a single-burner means having one burner), the second gas outlet passage 1300 needs to be blocked. For example, by using screws to block the second gas outlet passage 1300, gas cannot be discharged through it. When the air intake 1000 is applied to a gas stove with a double-burner design (a double-burner means having two burners), the first gas outlet passage 1200 corresponds to the first gas valve 3000, which corresponds to the first burner. The second gas outlet passage 1300 corresponds to the second gas valve, which corresponds to the second burner. Gas can be discharged from both the first gas outlet passage 1200 and the second gas outlet passage 1300. In other words, once the air intake seat 1000 is manufactured, it can be used in both single-burner gas stove designs (requiring the second gas outlet channel 1300 to be blocked) and double-burner gas stove designs (without requiring the second gas outlet channel 1300 to be blocked). This eliminates the need to produce two different specifications of air intake seat 1000, increasing its versatility and helping to reduce costs.

[0109] The second aspect of this application discloses a gas stove, combined with Figures 1 to 35As shown, the gas stove includes the aforementioned gas control device, which includes an inlet seat 1000, a control valve 2000, an adjusting element 5000, and a first gas valve 3000. The inlet seat 1000 is provided with an inlet channel 1100, a first outlet channel 1200, and an auxiliary channel 1400. The first outlet channel 1200 is connected to the inlet channel 1100, and the auxiliary channel 1400 is connected to the first outlet channel 1200 so that gas can flow from the auxiliary channel 1400 to the first outlet channel 1200. The auxiliary channel 1400 is provided with an inlet port 1410. The control valve 2000 and the inlet seat 1000 are connected... Next, the control valve 2000 includes a valve core 2200, which is movably configured to abut and disengage from the air inlet 1410. The valve core 2200 is adapted to close the air inlet 1410 when abutting it, and to open the air inlet 1410 when disengaging it, thereby connecting the air inlet 1410 with the air intake passage 1100. The adjusting member 5000 is connected to the air intake seat 1000 and is adapted to adjust the opening of the first air outlet passage 1200. The first gas valve 3000 is connected to the air intake seat 1000 and communicates with the first outlet 1233 of the first air outlet passage 1200.

[0110] By setting a first gas outlet channel 1200 and an auxiliary channel 1400 in the gas inlet seat 1000, both regular gas supply and high-heat gas supply to the first gas valve 3000 can be achieved without structural modifications to the first gas valve 3000. The first gas valve 3000 can use currently available mature products, offering strong compatibility and reducing structural complexity and cost. The first gas outlet channel 1200 also allows for opening adjustment via an adjusting component 5000, thus adapting to different gas sources and load sizes. It is understood that the gas control device of the gas stove in this embodiment adopts the technical solution of the above embodiment, and therefore possesses at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0111] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
