Description

Technical Field

[0001] This utility model relates to the field of gas stoves, and in particular to a valve body and gas stove with simultaneous dual flame control. Background Technology

[0002] Currently, the valves used in smart gas stoves with adjustable flame and temperature control are either proportional valves or on / off valves, or some smart temperature control stoves use valves that connect the outer and inner rings, with the inner ring having a throttling function. However, these existing solutions all have the following drawbacks:

[0003] The existing solution using proportional valves requires placing a regulating valve body in each of the two gas passages, one inside and one outside the stove, for flame adjustment and temperature control. This requires adding valve bodies to both gas passages, making the entire valve body structure very complex and bulky. Moreover, the valve body is very expensive, costing more than twice as much as a single intelligent control valve body structure. In some stoves with small bottom covers, there is not enough space available for its layout.

[0004] The existing solution using a switch valve requires a valve body structure that places a single switch valve in the outer ring gas passage. This means that the outer ring gas passage can only be closed, and the inner ring gas passage cannot be controlled. In high-efficiency stoves, this solution has poor temperature control, and the combustion of the inner ring flame can also provide a lot of heat for cooking, making it difficult to achieve the purpose of temperature control.

[0005] The existing scheme using an inner ring for throttling requires the outer ring gas passage to supply a portion of the gas to the inner ring gas passage via a connecting passage to ensure sufficient gas pressure. When the valve body closes, the outer ring gas passage is shut off, and the gas passage connecting to the inner ring is also cut off. The valve body relies on the throttling of the inner ring itself to discharge gas, achieving good temperature control. However, in practice, the valve body's own flame adjustment function is sacrificed. As long as there is gas supply to the outer ring passage, the inner ring gas passage will always have gas supplied from the outer ring, and the inner ring flame cannot be adjusted in size. Utility Model Content

[0006] Therefore, it is necessary to provide a valve body and gas stove that can simultaneously control the flame.

[0007] To solve the above-mentioned technical problems, this utility model provides a valve body with synchronous dual-control ignition, including a main body. The main body contains an inner ring gas passage, an outer ring gas passage, an adjusting chamber, a linkage through hole, and a linkage rod. The two ends of the linkage through hole are respectively connected to the inner ring gas passage and the outer ring gas passage. The linkage rod is slidably inserted into the linkage through hole. The adjusting chamber is located at and communicates with the outer ring gas passage. A first sealing part is slidably disposed within the adjusting chamber. A second sealing part is disposed at the end of the linkage rod near the inner ring gas passage, and the second sealing part is located within the linkage through hole. A driving device is disposed within the main body. The linkage rod and the first sealing part are both linked to the driving device. The driving device drives the linkage rod and the first sealing part to move, causing the first sealing part and the second sealing part to move synchronously, thereby adjusting the gas flow rate in the inner ring gas passage and the outer ring gas passage respectively.

[0008] Preferably, a baffle is provided at the position of the regulating cavity in the outer ring gas passage. The baffle divides the outer ring gas passage into a first section and a second section, and the baffle encloses a first closed cavity. The first closed cavity has a first opening directly opposite the regulating cavity and a second opening consistent with the extending direction of the outer ring gas passage. The regulating cavity communicates with the first section of the outer ring gas passage, the first opening communicates with the regulating cavity, the first closed portion matches the first opening, and the second opening communicates with the second section of the outer ring gas passage.

[0009] Preferably, the inner ring gas passage is provided with a second sealing cavity at the second sealing part, and the shape of the second sealing cavity is adapted to the shape of the second sealing part.

[0010] Preferably, the first sealing part is connected to one end of the linkage rod near the outer ring gas passage.

[0011] Preferably, the first closed part is connected to the output shaft of the drive device, the end of the linkage rod extends into the first closed cavity through the opening of the linkage through hole, the shape of the linkage through hole matches the shape of the linkage rod, and the end of the first closed part is provided with a limiting part, the width of the limiting part being greater than the diameter of the linkage through hole.

[0012] Preferably, the opening of the linkage through hole is located inside the first closed cavity, and a spring is sleeved on the first end of the linkage rod. One end of the spring abuts against the limiting part, and the other end abuts against the cavity wall of the first closed cavity.

[0013] Preferably, a sealing ring and a sealing pressure plate are sequentially fitted onto the opening of the linkage through hole on the linkage rod, and one end of the spring abuts against the limiting part and the other end abuts against the sealing pressure plate.

[0014] Preferably, the driving device is a motor.

[0015] Preferably, the driving device is a cylinder.

[0016] This utility model also provides a gas stove, including an inner gas ring, an outer gas ring, a gas valve switch, a temperature control switch, and the valve body. The inlet of the inner gas ring and the inlet of the outer gas ring are respectively connected to the gas valve switch. The outlet of the inner gas ring is connected to the inner gas ring, and the outlet of the outer gas ring is connected to the outer gas ring. The gas valve switch is used to control the igniter and provide gas to the inner and outer gas rings. The temperature control switch is used to control the drive device.

[0017] The beneficial effects of this utility model are as follows: The valve body of this patented technical solution, by adding a linkage rod, a first sealing part, and a second sealing part to the valve body, achieves both isolation of the inner and outer ring gas passages and simultaneous transmission of the switching valve action. Through ingenious application and design of the structure, while ensuring the original function of the valve body, a single switching valve enables free and convenient control of the gas flow in both the inner and outer gas passages, allowing for synchronous control of the large and small flames in the inner and outer rings.

[0025] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0026] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] refer to Figures 1-5This utility model provides a valve body with synchronous dual-control ignition, including a body 1. The body 1 contains an inner ring gas channel 4, an outer ring gas channel 5, an adjusting chamber 2, a linkage through hole, and a linkage rod 6. The two ends of the linkage through hole are respectively connected to the inner ring gas channel 4 and the outer ring gas channel 5. The linkage rod 6 is slidably inserted into the linkage through hole. The adjusting chamber 2 is located at and communicates with the outer ring gas channel 5. A first sealing part 7 is slidably disposed within the adjusting chamber 2. A second sealing part 8 is disposed at one end of the linkage rod 6 near the inner ring gas channel 4, and the second sealing part 8 is located within the linkage through hole. A driving device 3 is disposed within the body 1. The linkage rod 6 and the first sealing part 7 are both linked to the driving device 3. The driving device 3 drives the linkage rod 6 and the first sealing part 7 to move, causing the first sealing part 7 and the second sealing part 8 to move synchronously, thereby adjusting the gas flow rate in the inner ring gas channel 4 and the outer ring gas channel 5 respectively. Optionally, the driving device 3 is a switching valve. This patented technical solution utilizes a valve body with a linkage rod 6, a first sealing part 7, and a second sealing part 8, among other sealing connection mechanisms, to achieve both isolation of the inner and outer ring gas passages and simultaneous transmission of the on / off valve action. Through ingenious structural application and design, while maintaining the original functions of the valve body, a single on / off valve enables free and convenient control of the gas flow in both the inner and outer gas passages, allowing for simultaneous control of the large and small flames in both the inner and outer rings. Compared to existing products on the market, this application uses fewer on / off valves, proportional valves, and motor valves, resulting in lower costs, while ensuring that the original flame control and adjustment functions of the valve body remain unaffected.

[0029] In a preferred embodiment, a baffle 9 is provided at the position of the regulating cavity 2 in the outer ring gas passage 5. The baffle 9 divides the outer ring gas passage 5 into a first passage and a second passage, forming a first closed cavity 10. The first closed cavity 10 has a first opening 101 directly opposite the regulating cavity 2 and a second opening 102 aligned with the extending direction of the outer ring gas passage 5. The regulating cavity 2 communicates with the first passage of the outer ring gas passage 5, the first opening 101 communicates with the regulating cavity 2, the first sealing part 7 matches the first opening 101, and the second opening 102 communicates with the second passage of the outer ring gas passage 5. Thus, by sealing the first opening 101 with the first sealing part 7, the opening and closing of the first opening 101 can control and cut off the gas flow in the outer ring gas passage 5. When the first sealing part 7 and the second sealing part 8 are driven downward by the driving device 3, the first sealing part 7 gradually seals the first opening 101, and the outer ring gas passage 5 is closed. The second sealing part 8 at the end of the linkage rod 6 penetrates into the second sealing cavity 11 of the inner ring gas passage 4, and the flow area of ​​the inner ring gas passage 4 is drastically reduced, forming a throttling effect. At this time, the first sealing part 7 closes the outer ring gas passage 5, and no airflow passes through. The inner ring gas passage 4 is throttled, and only a weak airflow passes through. This achieves synchronous control of the changes in the large and small flames of the inner and outer rings.

[0030] In a preferred embodiment, the inner ring gas passage 4 is provided with a second sealing cavity 11 at the second sealing part 8, and the shape of the second sealing cavity 11 is adapted to the shape of the second sealing part 8; in this way, the second sealing part 8 blocks the second sealing cavity 11, so that the movement of the second sealing part 8 can control the gas flow rate in the inner ring gas passage 4.

[0031] In a preferred embodiment, the first sealing part 7 is connected to one end of the linkage rod 6 near the outer ring gas passage.

[0032] In a preferred embodiment, the first sealing part 7 is connected to the output shaft of the driving device 3, and the end of the linkage rod 6 extends into the first sealed cavity through the opening of the linkage through hole. The shape of the linkage through hole matches the shape of the linkage rod 6. The end of the first sealing part 7 is provided with a limiting part 61, and the width of the limiting part 61 is greater than the diameter of the linkage through hole.

[0033] In a preferred embodiment, the opening of the linkage through hole is located inside the first closed cavity 10, and a spring 61 is sleeved on the first end of the linkage rod 6. The first end of the spring 61 abuts against the limiting part 61, and the second end of the spring 61 abuts against the cavity wall of the first closed cavity 10.

[0034] In a preferred embodiment, a sealing ring 64 and a sealing pressure plate 63 are sequentially fitted onto the linkage rod 6 at the opening of the linkage through hole. The first end of the spring 61 abuts against the limiting part 61, and the second end of the spring 61 abuts against the sealing pressure plate 63. More preferably, a limiting groove for accommodating the spring 61 is provided at the opening of the linkage through hole, thereby limiting the movement of the spring 61.

[0035] In a preferred embodiment, the drive device 3 is a switching valve, or the drive device 3 is a motor, or the drive device 3 is a cylinder.

[0036] Workflow: By opening and closing the switch valve 3, force is pushed in through the sealing connection mechanism. When the temperature control and flame adjustment function is activated, by opening the switch valve 3, the first sealing part 7 and the second sealing part 8 on the sealing connection mechanism are pressed down and moved. When the first sealing part 7 completely seals the first opening 101, the outer ring gas passage 5 is closed. The second sealing part 8 at the end of the linkage rod 6 penetrates into the second sealed cavity 11 of the inner ring gas passage 4, and the flow area of ​​the inner ring gas passage 4 is drastically reduced, forming a throttling effect. At this time, the gas supplied to the inner ring gas passage 4 is reduced, and the inner ring flame will become smaller. At this time, the first sealing part 7 closes the outer ring gas passage 5, and no airflow passes through. The inner ring gas passage 4 is throttled, and only a weak airflow passes through. This achieves synchronous control of the changes in the size of the inner and outer ring flames.

[0037] When the switch valve 3 is closed, the switch valve 3 returns upward, the first opening 101 between the regulating chamber 2 and the first closed chamber 10 opens, the outer ring gas passage 5 is restored to unobstructed flow, gas is supplied, and the outer ring flame is ignited.

[0038] At the same time, the spring 62 returns to its original state and applies force to the limiting part 61, so that the linkage rod 6 moves upward under the action of the spring 62's rebound force. The second closed part 8 at the end of the linkage rod 6 gradually retracts from the second closed cavity 11 of the inner ring gas passage 4 back into the linkage through hole. At this time, the throttling phenomenon of the inner ring gas passage 4 disappears, the gas supply of the inner ring gas passage 4 to the inner ring increases, and the inner ring flame becomes larger.

[0039] This utility model also provides a gas stove, including an inner gas ring 12, an outer gas ring 13, a gas valve switch 14, a temperature control switch 15, and a valve body 16. The inlet 41 of the inner ring gas channel 4 and the inlet 51 of the outer ring gas channel 5 are respectively connected to the gas valve switch 14. The outlet 42 of the inner ring gas channel 4 is connected to the inner gas ring 12, and the outlet 52 of the outer ring gas channel is connected to the outer gas ring 13. The gas valve switch 14 is used to control the igniter to ignite and provide gas to the inner ring gas channel 4 and the outer ring gas channel 5. The temperature control switch 15 is used to control the drive device 3, thereby regulating the gas flow rate through the inner ring gas channel 4 and the outer ring gas channel 5. The temperature control switch is electrically connected to the drive device 3.

[0040] This application uses a steady-state valve or a switching valve. The opening and closing of the valve body synchronously transmits the force of the valve body to the first sealing part 7 and the second sealing part 8. When the temperature control and flame adjustment function is activated, when the steady-state valve body is opened, the first sealing part 7 closes the first opening 101, thereby closing the outer ring gas passage 5. Simultaneously, the second sealing part 8 at the end of the linkage rod 6 penetrates into the second sealing cavity 11 of the inner ring gas passage, drastically reducing the flow area of ​​the inner ring gas passage 4, thus creating a throttling effect. At this time, the outer ring gas passage is closed, with no airflow, and the inner ring gas passage is throttled, with only a weak airflow passing through.

[0041] The valve body of this application achieves both isolation of the inner and outer gas passages and simultaneous transmission of the on / off valve action. Through ingenious structural application and design, while maintaining the original functions of the valve body, a single on / off valve enables free and convenient control of the gas flow in both gas passages, allowing for simultaneous control of the large and small flames in the inner and outer rings. Compared to existing products on the market, this application uses fewer on / off valves, proportional valves, and motor valves, resulting in lower costs, while ensuring that the original flame control function of the valve body remains unaffected. Furthermore, the design scheme of this application is compatible with all pipe-driven stove valve bodies on the market, offering extremely high versatility and economy. Compared to existing intelligent temperature control valve body solutions on the market, it is also more cost-effective, creating significant economic value for enterprises.
