[0038] Reference Figures 1 to 8 An embodiment of the present invention provides a gas control valve, which includes a valve body 100, an adjusting rod 200, and an adjusting plate 300.

[0039] The valve body 100 is provided with an air inlet chamber 110 and two air outlet channels, including a first air outlet channel 120 and a second air outlet channel 130. The bottom wall of the air inlet chamber 110 is provided with two openings, including a first opening 111 and a second opening 112. The first opening 111 communicates with the first air outlet channel 120, and the second opening 112 communicates with the second air outlet channel 130. The valve body 100 is provided with an air inlet hole 140 communicating with the air inlet chamber 110. An adjusting rod 200 is rotatably mounted on the valve body 100, and an adjusting plate 300 is sleeved on the adjusting rod 200. The regulating plate 300 is located in the air intake chamber 110. The regulating plate 300 abuts against the bottom wall of the air intake chamber 110. The regulating plate 300 has a default space, which includes a through hole 320 and a notch 310 located on the periphery of the regulating plate 300. The notch 310 is used to communicate with the first port 111. The regulating plate 300 has a through hole 320, which is used to communicate with the second port 112. Both the notch 310 and the through hole 320 have an arc-shaped structure. The regulating plate 300 can rotate with the regulating rod 200 to open or close the first port 111 and the second port 112.

[0040] In this embodiment, refer to Figure 5 , Figure 6 , Figure 7 as well as Figure 8 The adjusting plate 300 can rotate with the adjusting rod 200 to rotate sequentially from the first position 810 to the second position 820, the third position 830 and the fourth position 840.

[0041] When the adjusting plate 300 is in the first position 810, the adjusting plate 300 closes the first port 111 and the second port 112.

[0042] When the adjusting plate 300 is in the second position 820, the adjusting plate 300 closes the second port 112 and opens the first port 111 through the notch 310.

[0043] When the adjusting plate 300 is in the third position 830, the adjusting plate 300 opens the first port 111 through the notch 310 and opens the second port 112 through the through hole 320.

[0044] When the adjusting plate 300 is in the fourth position 840, the adjusting plate 300 closes the first port 111 and opens the second port 112 through the through hole 320.

[0045] It should be noted that the first position 810, the second position 820, the third position 830 and the fourth position 840 do not refer to a specific position, but rather to positions within a preset rotation angle range. Therefore, it can be understood that when the adjusting plate 300 is in the first position 810, that is, when the adjusting plate 300 is within the first preset rotation range, the adjusting plate 300 closes the first port 111 and the second port 112.

[0046] With the above structure, the default space of the regulating plate can be obtained through processes such as stamping and cutting. Therefore, the structure of the regulating plate is simpler than that of the valve core, and the processing technology of the regulating plate is simpler than that of the valve core, thereby reducing production costs.

[0047] In some embodiments, both the air outlet channel and the port are set to one, and the default space only includes the through hole 320.

[0048] The adjusting plate 300 is sleeved on the adjusting rod 200, and the adjusting plate 300 abuts against the cavity wall of the air intake chamber 110. For details, please refer to... Figure 2 and Figure 3 An adjusting plate 300 is slidably sleeved on an adjusting rod 200. The adjusting rod 200 is fitted with a first elastic element 410, which is located in the air intake chamber 110. One end of the first elastic element 410 abuts against one of the chamber walls of the air intake chamber 110, and the other end abuts against the adjusting plate 300. The first elastic element 410 is used to drive the adjusting plate 300 to abut against the other chamber wall of the air intake chamber 110. The first elastic element 410 is a spring.

[0049] It is understandable that the other cavity wall mentioned above is the bottom wall of the air intake cavity 110.

[0050] The above structure enables the gas control valve to maintain contact between the regulating plate 300 and the cavity wall of the air intake chamber 110 even during bumpy transportation.

[0051] In order to detect the rotation of the adjusting lever 200 from the first position 810, refer to... Figure 3 and Figure 4 A detection switch 500 is provided on the outer side of the valve body 100. A notch 210 is provided on the outer side wall of the adjusting rod 200 outside the valve body 100. The contact block 510 of the detection switch 500 abuts against the adjusting rod 200. When the adjusting plate 300 is in the first position 810, the contact block 510 of the detection switch 500 is located in the notch 210. The detection switch 500 is configured as a micro switch or the like.

[0052] It is understood that the contact point of the contact block 510 at the notch 210 and the adjustment rod 200 is A, the distance from A to the axis of the adjustment rod 200 is L1, the point where the contact block 510 rotates to abut against the outer wall of the adjustment rod 200 is B, the distance from B to the axis of the adjustment rod 200 is L2, where L1 < L2.

[0053] When the adjusting plate 300 starts to rotate from the first position 810, the contact point between the contact block 510 and the adjusting rod 200 switches from A to B. Therefore, the contact block 510 deforms, which in turn causes the detection switch 500 to generate a signal.

[0054] Reference Figure 1 , Figure 2 as well as Figure 3 The valve body 100 has a first air passage 150, which connects to a second port 112 and a second air outlet 130. The valve body 100 also has a temperature control device 600. The output end of the temperature control device 600 is located in the second air outlet 130, and the output end of the temperature control device 600 is equipped with a sealing cap 700. The input end of the temperature control device 600 is located outside the valve body 100. When the temperature at the input end of the temperature control device 600 reaches a preset value, the output end of the temperature control device 600 moves to drive the sealing cap 700 to move closer to the outlet of the first air passage 150. The temperature control device 600 is a thermostatic expansion valve. The input end of the temperature control device 600 is equipped with a temperature sensing bulb. When the temperature of the temperature sensing bulb reaches the preset value, the medium inside the temperature control device 600 expands due to heat, driving the output end of the temperature control device 600 to move, thereby driving the sealing cap 700 to move closer to the outlet of the first air passage 150.

[0055] Understandably, when the temperature of the temperature sensing bulb decreases, the medium inside the temperature control device 600 contracts, causing the cover 700 to move away from the outlet of the first venting channel 150.

[0056] It is understandable that the first air passage 150 is connected to the second port 112 and the second air outlet 130, that is, the inlet of the first air passage 150 is connected to the second port 112, and the outlet of the first air passage 150 is connected to the second air outlet 130.

[0057] It is understandable that the gas flows sequentially from the second port 112 and the first gas passage 150 to the second gas outlet 130, referring to... Figure 2 As indicated by the solid arrow.

[0058] In this embodiment, refer to Figure 2 and Figure 3The cover 700 is provided with a connecting rod 710. One end of the adjusting rod 200 is provided with a connecting hole 220. One end of the connecting rod 710 is inserted into the connecting hole 220 and can move along the axial direction of the adjusting rod 200. The other end of the connecting rod 710 is threadedly connected to the temperature control device 600. A second elastic element 420 is provided between the temperature control device 600 and the cover 700. When the adjusting rod 200 rotates, it can drive the connecting rod 710 to rotate, so that the cover 700 opens or closes the first air passage 150. The second elastic element 420 is a spring.

[0059] When the adjusting rod 200 rotates in the rotation direction, the adjusting rod 200 drives the connecting rod 710 to rotate through the connecting hole 220, so that the connecting rod 710 moves at the output end of the temperature control device 600 in a direction away from the outlet of the first gas passage 150, thereby causing the cover 700 to move in a direction away from the outlet of the first gas passage 150, making it easier for gas to enter the second gas outlet passage 130 from the first gas passage 150.

[0060] In order to ensure that the second exhaust passage 130 maintains a certain amount of exhaust, refer to Figure 2 The valve body 100 is provided with a second air passage 160, which is connected to the second port 112 and the second air outlet 130.

[0061] It is understandable that the second air passage 160 is connected to the second port 112 and the second air outlet 130, that is, the inlet of the second air passage 160 is connected to the second port 112, and the outlet of the second air passage 160 is connected to the second air outlet 130.

[0062] It is understandable that the gas flows sequentially from the second port 112 and the second gas passage 160 to the second gas outlet 130, referring to... Figure 2 As indicated by the dashed arrow.

[0063] This invention also proposes a gas appliance including the aforementioned gas control valve. The gas appliance can be configured as a gas stove, gas water heater, etc. This structure reduces the production cost of the gas appliance.

[0064] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
