[0002] Currently, commonly used gas control valves typically consist of a valve body, a valve core, and a valve stem connected to the valve core. The gas flow rate is adjusted by pressing and turning the valve stem. To facilitate operation of the valve stem, a knob is usually installed on the top of the valve stem, with a knob light on it to help users identify the gas flow rate.

[0003] In the prior art, a touch switch is usually provided on the knob to control the on and off of the knob light. Since the touch switch is usually installed inside the knob and a protective screen is provided on the surface of the knob to isolate and protect the touch switch, when the touch switch fails, it is troublesome, time-consuming and labor-intensive to repair and replace the touch switch. If the entire knob is directly replaced, the repair cost will be high.

[0041] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0042] Reference Figures 1 to 6One embodiment of the present invention provides a gas control valve, comprising a valve body 100, a lighting switch 200, and a first pressing member 300. The valve body 100 is movably mounted with a valve stem 110, the valve stem 110 having a central axis, and the valve stem 110 can move along the central axis and can rotate around the central axis. The lighting switch 200 is mounted on the outer wall of the valve body 100, and a first triggering portion 210 is provided on the side of the lighting switch 200 facing the valve stem 110. The first pressing member 300 is mounted on the valve stem 110 and can rotate around the central axis following the valve stem 110, and the first pressing member 300 is provided with a first pressing portion 310. When the valve stem 110 drives the first pressing member 300 to rotate relative to the valve body 100, the first pressing portion 310 can be squeezed or separated from the first triggering portion 210.

[0043] By adopting the gas control valve of the embodiment of the present invention, a lighting switch 200 capable of controlling the lighting or extinguishing of the knob light is installed on the valve body 100, and a first pressing member 300 is provided on the valve stem 110. When in use, the knob light is electrically connected to the lighting switch 200. When the valve stem 110 drives the first pressing member 300 to rotate relative to the valve body 100, the first pressing portion 310 of the first pressing member 300 can be squeezed or separated from the first triggering portion 210 of the lighting switch 200. In this way, the lighting switch 200 can be controlled to work or not by rotating the valve stem 110, thereby controlling the lighting or extinguishing of the knob light. The gas control valve of the embodiment of the present invention controls the operation of the lighting switch 200 by mechanical control, and is not easily affected by external oil smoke or dust, which may cause the control of the lighting switch 200 to fail, and has high sensitivity. In addition, since the lighting switch 200 is directly installed on the outer wall of the valve body 100, when the lighting switch 200 fails, the lighting switch 200 can also be easily replaced and repaired without replacing the entire knob or the entire gas control valve, thereby reducing the maintenance cost of the gas control valve.

[0044] Reference Figures 1 to 6 In some embodiments, the first trigger portion 210 is specifically a raised portion provided on the side of the lighting switch 200 facing the valve stem 110, thereby enabling effective squeezing between the first pressing portion 310 and the first trigger portion 210, thereby triggering the lighting switch 200, reducing the risk of the lighting switch 200 being unable to be used normally due to squeezing failure between the first pressing portion 310 and the first trigger portion 210.

[0045] Reference Figures 1 to 6 In some embodiments, the first pressing member 300 is fixedly mounted on the valve stem 110 , and the first pressing portion 310 is protrudingly disposed on the outer peripheral wall of the first pressing member 300 . The first pressing portion 310 can follow the valve stem 110 and move relative to the first trigger portion 210 along the central axis.

[0046] By adopting the above structure, the first pressing member 300 is fixedly installed on the valve stem 110, so that the installation structure of the first pressing member 300 is simple and convenient for production and assembly. When the valve stem 110 moves relative to the valve body 100 along the central axis, the first pressing member 300 can move synchronously with the valve stem 110, and the first pressing portion 310 can move relative to the first trigger portion 210, thereby avoiding relative movement between the first pressing member 300 and the valve stem 110, which may cause unstable rotation of the first pressing member 300, so that the first pressing portion 310 can stably follow the rotation of the valve stem 110 and squeeze or separate from the first trigger portion 210 of the lighting switch 200.

[0047] It is understandable that the first pressing member 300 is fixedly mounted on the valve stem 110 and is only for Figures 1 to 6 As an example, in some embodiments, the first pressing member 300 can be movably mounted on the valve stem 110, such that the valve stem 110 can move relative to the first pressing member 300 along the central axis, and the valve stem 110 can drive the first pressing member 300 to rotate about the central axis. The present invention does not specifically limit the specific mounting structure between the first pressing member 300 and the valve stem 110.

[0048] It is understandable that, referring to Figures 1 to 6 In some embodiments, the first pressing portion 310 is protruding from the outer peripheral wall of the first pressing member 300, and a transition curved surface 320 is provided between the first pressing portion 310 and the outer peripheral wall of the first pressing member 300, thereby preventing the first pressing member 300 from rotating jamming when the first pressing portion 310 rotates from a position separated from the first trigger portion 210 to a position where it is squeezed with the first trigger portion 210, or when the first pressing portion 310 rotates from a position where it is squeezed with the first trigger portion 210 to a position where it is separated from the first trigger portion 210, thereby making the rotation process of the first pressing member 300 smoother and more stable, and also making the rotation of the first pressing member 300 easier and more labor-saving, which is convenient for users to operate.

[0049] Reference Figures 1 to 7 In some embodiments, the valve body 100 is provided with a valve cavity 120, and a gas passage communicating with the valve cavity 120 is provided on the side wall of the valve body 100. A valve core 130 connected to the valve stem 110 is installed in the valve cavity 120, and the valve stem 110 can drive the valve core 130 to rotate and control the on-off of the gas passage; wherein, when the valve core 130 closes the gas passage, the first pressing portion 310 and the first triggering portion 210 squeeze each other, and the lighting switch 200 is turned off; when the valve stem 110 drives the valve core 130 to rotate to open the gas passage, the first pressing portion 310 rotates with the valve stem 110 and separates from the first triggering portion 210, and the lighting switch 200 is turned on.

[0050] By adopting the above structure, when the valve core 130 closes the gas channel, the lighting switch 200 is turned off, so that the knob light is in an extinguished state, and the first pressing portion 310 and the first trigger portion 210 are in a mutually squeezed state; when the valve stem 110 rotates to adjust the gas flow in the gas channel, the lighting switch 200 is turned on, so that the knob light is in a lit state, and the first pressing portion 310 rotates relative to the first trigger portion 210 and is in a mutually separated state with the first trigger portion 210, thereby making the adjustment of the gas flow easier and more labor-saving, and convenient for user operation.

[0051] It is understood that when the valve core 130 closes the gas passage, the first pressing portion 310 and the first trigger portion 210 press against each other, and the lighting switch 200 is closed; when the valve stem 110 drives the valve core 130 to rotate to open the gas passage, the first pressing portion 310 rotates with the valve stem 110 and separates from the first trigger portion 210, and the lighting switch 200 is turned on. This is merely an exemplary description of the present invention. In addition, in some embodiments, when the valve core 130 closes the gas passage, the first pressing portion 310 and the first trigger portion 210 separate from each other, and the lighting switch 200 is closed; when the valve stem 110 drives the valve core 130 to rotate to open the gas passage, the first pressing portion 310 rotates with the valve stem 110 and presses against the first trigger portion 210, and the lighting switch 200 is turned on. The present invention does not impose any specific limitation on this.

[0052] It can be understood that the above-mentioned gas channel specifically includes an air inlet channel 123 and an air outlet channel 124 opened on the side wall of the valve body 100 and connected to the valve cavity 120. The valve stem 110 can drive the valve core 130 to rotate to control the on and off of the air outlet channel 124, thereby controlling the air outlet flow rate of the gas.

[0053] Reference Figures 1 to 9 In some embodiments, the gas control valve further includes an ignition switch 400 and a second pressing member 500. The ignition switch 400 is mounted on the valve body 100. A second trigger portion 410 is provided on the side of the ignition switch 400 facing the valve stem 110. The second pressing member 500 is mounted on the valve stem 110 and can move along the central axis with the valve stem 110. The second pressing member 500 is provided with a second pressing portion 510. When the valve stem 110 moves toward the inside of the valve body 100, the second pressing portion 510 can abut against the second trigger portion 410.

[0054] By adopting the above structure, the ignition switch 400 can be electrically connected to the igniter during use. Therefore, when the valve stem 110 is pressed and moved toward the interior of the valve body 100, the second pressing member 500 can follow the movement of the valve stem 110 and cause the second pressing portion 510 to abut against the second trigger portion 410, thereby turning on the ignition switch 400 and controlling the ignition of the igniter. The installation of the ignition switch 400 makes ignition more convenient. Ignition can be achieved by simply pressing the valve stem 110. In addition, since the ignition switch 400 is installed on the valve body 100, it can also be easily replaced and repaired.

[0055] It can be understood that when the valve stem 110 moves toward the inside of the valve body 100, the second pressing portion 510 can abut against the second trigger portion 410 and make the ignition switch 400 work. Specifically, in some embodiments, the valve chamber 120 includes a valve core chamber 121 and a solenoid valve chamber 122, the valve core 130 is installed in the valve core chamber 121, the solenoid valve 180 is installed in the solenoid valve chamber 122, and the gas channel includes an air inlet channel 123 and an air outlet channel 124. The air inlet channel 123 is opened on the side wall of the valve body 100 and is connected to the solenoid valve chamber 122, and the air outlet channel 124 is opened on the valve body 100 and is connected to the valve core chamber 121. When the valve stem 110 moves along the central axis and approaches the solenoid valve 180, the valve stem 110 can abut against the solenoid valve 180 and trigger the solenoid valve 180 to work, so that the solenoid valve 180 can control the solenoid valve chamber 122 to communicate with each other. Therefore, when the valve stem 110 is pressed to move the valve stem 110 toward the inside of the valve body 100, the valve stem 110 can trigger the solenoid valve 180 to communicate with each other about the intake channel 123 and the valve core chamber 121, thereby opening the gas channel, and the second pressing portion 510 can follow the valve stem 110 to move to abut against the second triggering portion 410, thereby turning on the ignition switch 400 and controlling the ignition of the igniter.

[0056] Reference Figures 1 to 9 In some embodiments, the second trigger portion 410 is specifically a raised portion provided on the side of the ignition switch 400 facing the valve stem 110, thereby enabling effective squeezing between the second pressing portion 510 and the second trigger portion 410, thereby triggering the ignition switch 400, reducing the risk of the ignition switch 400 being unable to be used normally due to squeezing failure between the second pressing portion 510 and the second trigger portion 410.

[0057] Reference Figures 1 to 9 In some embodiments, the valve body 100 is provided with a guide surface 141 extending outward along the pressing direction of the valve stem 110, the second pressing member 500 has an elastic portion 520, and the second pressing portion 510 is connected to the elastic portion 520; when the valve stem 110 moves along the pressing direction, the elastic portion 520 can abut against the guide surface 141 and move outward along the guide surface 141 to approach the second trigger portion 410.

[0058] In the above structure, the pressing direction specifically refers to the direction of movement along the central axis toward the interior of the valve cavity 120. When the valve stem 110 is pressed, the valve stem 110 can drive the second pressing member 500 to move toward the interior of the valve cavity 120. During this process, the elastic member can abut against the guide surface 141 and deform, moving outward along the guide surface 141 toward the second triggering portion 410, causing the second pressing portion 510 and the second triggering portion 410 to press against each other, triggering the ignition switch 400.

[0059] It is understandable that the elastic portion 520 can abut against the guide surface 141 and move outward along the guide surface 141 to approach the second trigger portion 410. Figures 1 to 9 As an exemplary illustration, in some embodiments, the second pressing portion 510 may be brought into contact with the guide surface 141 and moved outwardly along the guide surface 141 toward the second trigger portion 410. When the valve stem 110 is pressed, the valve stem 110 can drive the second pressing member 500 to move toward the interior of the valve cavity 120. At this time, the elastic portion 520 can be deformed, allowing the second pressing portion 510 to be brought into contact with the guide surface 141 and moved outwardly along the guide surface 141 toward the second trigger portion 410, thereby squeezing each other. In addition, in some embodiments, both the second pressing portion 510 and the elastic portion 520 may be brought into contact with the guide surface 141 and moved outwardly along the guide surface 141 toward the second trigger portion 410. This is not specifically limited in the present invention.

[0060] Reference Figures 1 to 9 In some embodiments, in the second pressing member 500, a connecting portion 530 is further provided between the elastic portion 520 and the second pressing portion 510. One end of the connecting portion 530 is connected to the elastic portion 520, and the other end is connected to the pressing portion. The connecting portion 530 can be adapted to the guide surface 141. Thus, when the valve stem 110 is pressed, the valve stem 110 can drive the second pressing member 500 to move toward the inside of the valve cavity 120. During this process, the connecting portion 530 is in contact with the guide surface 141 and can move along the guide surface 141, thereby causing the elastic portion 520 to deform, and then the second pressing portion 510 can move outward close to the second trigger portion 410 and squeeze each other with the second trigger portion 410, thereby triggering the ignition switch 400.

[0061] Reference Figures 1 to 9 In some embodiments, the second pressing member 500 is rotatably mounted on the valve stem 110, and the valve body 100 is provided with a limiting groove 140 arranged opposite to the second trigger portion 410. The limiting groove 140 is arranged along the length direction of the valve stem 110. The second pressing portion 510 is located in the limiting groove 140 and can move along the limiting groove 140. The guide surface 141 is arranged on the inner wall of the limiting groove 140.

[0062] In the above structure, the provision of the limiting groove 140 can limit the rotation of the second pressing member 500, so that when the valve stem 110 drives the second pressing member 500 to move along the central axis, the second pressing portion 510 can move along the limiting groove 140. When the valve stem 110 is rotated to adjust the gas flow rate, the second pressing portion 510 can be confined within the limiting groove 140 and cannot rotate with the valve stem 110, thus allowing the valve stem 110 to rotate relative to the second pressing member 500. In addition, by providing the guide surface 141 on the inner wall of the limiting groove 140, since the second pressing portion 510 is always located within the limiting groove 140, when the valve stem 110 is pressed downward, the second pressing portion 510 and / or the elastic portion 520 can accurately abut against the guide surface 141 and move along the guide surface 141, thereby making the ignition switch 400 more accurately turned on.

[0063] Reference Figure 9 In some embodiments, the second pressing member 500 can be specifically configured as an integrally formed spring structure, which has a simple structure and is easy to produce and process.

[0064] Reference Figures 1 to 9 In some embodiments, the second pressing member 500 is located above the first pressing member 300 and abuts against the first pressing member 300 , and the valve stem 110 is equipped with a pressing piece 150 that presses against the upper surface of the second pressing member 500 .

[0065] By adopting the above structure, the second pressing member 500 is pressed against the upper surface of the first pressing member 300, and then the pressing sheet 150 is pressed against the upper surface of the second pressing member 500, thereby realizing the installation and assembly of the first pressing member 300 and the second pressing member 500, making the structure of the gas control valve more compact and stable, and the disassembly and assembly is also relatively simple and convenient, thereby facilitating the replacement and maintenance of the first pressing member 300 and the second pressing member 500, making the maintenance of the gas control valve more convenient.

[0066] Reference Figures 1 to 9 In some embodiments, a mounting hole communicating with the valve cavity 120 is formed on the top wall of the valve body 100, and the valve stem 110 is movably mounted in the mounting hole. The first pressing member 300 is provided with a limiting portion 331 capable of limiting the movement stroke of the valve stem 110. When the valve stem 110 drives the first pressing member 300 to move toward the valve cavity 120, the limiting portion 331 can abut against the outer peripheral edge of the mounting hole.

[0067] By adopting the above structure, the setting of the limiting portion 331 can limit the travel of the valve stem 110 along the central axis. When the valve stem 110 is pressed until the limiting portion 331 abuts against the outer periphery of the mounting hole, the valve stem 110 moves to the extreme position and can no longer move further into the valve cavity 120, thereby limiting the valve stem 110 and preventing continuous pressing that causes the valve stem 110 to completely enter the valve cavity 120, thereby making the structure of the gas control valve more stable and compact.

[0068] Reference Figures 1 to 9 In some embodiments, the bottom wall of the first pressure member 300 is provided with a bottom groove 330, which is sleeved on the outer peripheral wall of the mounting hole, and a limiting portion 331 is located on the top wall of the bottom groove 330. Thus, when the valve stem 110 moves along the central axis, the first pressure member 300 follows the valve stem 110 and causes the inner peripheral wall of the bottom groove 330 and the outer peripheral edge of the mounting hole to move closer to or farther from each other. When the valve stem 110 moves until the limiting portion 331 abuts the outer peripheral edge of the mounting hole, the valve stem 110 is at its limit position. In this structure, the provision of the bottom groove 330 can further guide the movement of the first pressure member 300 along the central axis, preventing the valve stem 110 and / or the first pressure member 300 from shifting or shaking during movement, thereby making the structure of the gas control valve more compact and the movement of the valve stem 110 and the first pressure member 300 more compact.

[0069] Reference Figures 1 to 9 In some embodiments, a first mounting seat 160 and a second mounting seat 170 are provided on the outer wall of the valve body 100 . The first mounting seat 160 and the second mounting seat 170 are staggered in the circumferential direction of the valve body 100 . The lighting switch 200 is installed on the first mounting seat 160 , and the ignition switch 400 is installed on the second mounting seat 170 .

[0070] By adopting the above structure, the first mounting seat 160 and the second mounting seat 170 are arranged on the outer wall of the valve body 100, thereby facilitating the installation of the light switch 200 and the ignition switch 400, and also facilitating the replacement and maintenance of the light switch 200 and the ignition switch 400. In addition, by staggering the first mounting seat 160 and the second mounting seat 170 in the circumferential direction of the valve body 100, interference between the light switch 200 and the ignition switch 400 can be avoided during assembly or disassembly or during use.

[0071] It is understood that the lighting switch 200 is mounted on the first mounting seat 160. Specifically, the lighting switch 200 can be mounted on the first mounting seat 160 using fasteners such as screws and bolts, or can be mounted on the first mounting seat 160 using a snap or hook structure, and this is not specifically limited in this utility model. Similarly, it is understood that the ignition switch 400 is mounted on the second mounting seat 170. Specifically, the ignition switch 400 can be mounted on the second mounting seat 170 using fasteners such as screws and bolts, or can be mounted on the second mounting seat 170 using a snap or hook structure, and this is not specifically limited in this utility model.

[0072] An embodiment of the present invention further provides a gas appliance provided with a gas control valve according to any of the above embodiments, wherein a knob is mounted on the outer end of the valve stem 110 , the knob having a knob light, and the knob light is electrically connected to the lighting switch 200 .

[0073] In the above structure, by adopting the gas control valve of any of the above embodiments, a knob is installed on the outer end of the valve stem 110, and the knob light of the knob is electrically connected to the lighting switch 200 of the gas control valve. Therefore, when the valve stem 110 drives the first pressing member 300 to rotate relative to the valve body 100 to adjust the gas flow rate, the first pressing portion 310 of the first pressing member 300 can be squeezed or separated from the first triggering portion 210 of the lighting switch 200. Therefore, the lighting switch 200 can be controlled to work or not by rotating the valve stem 110, thereby controlling the lighting or extinguishing of the knob light. The gas control valve of the embodiment of the present invention controls the operation of the lighting switch 200 by mechanical control, and is not easily affected by external oil smoke or dust, which may cause the control of the lighting switch 200 to fail. It has high sensitivity, which makes it easy for users to use and improves the user experience when using gas appliances. Moreover, since the lighting switch 200 is directly installed on the outer wall of the valve body 100, when the lighting switch 200 fails, it is also convenient to replace and repair the lighting switch 200, thereby reducing the impact of damage to the lighting switch 200 on the use of gas appliances.

[0074] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
