Description

Technical Field

[0001] This utility model relates to the field of gas appliance technology, and in particular to a gas control valve and a gas appliance. Background Technology

[0002] Currently, commonly used gas control valves typically include a valve body, a valve core, and a valve stem connected to the valve core. An ignition switch electrically connected to the igniter is installed on the valve body. Pressing the valve stem triggers the ignition switch, and rotating the valve stem controls the gas flow rate, thus adjusting the flame intensity. In actual use, gas stoves, ovens, and other gas appliances usually require additional auxiliary equipment, such as indicator knobs, lighting fixtures, and ventilation systems. These auxiliary devices can be configured to operate after the gas appliance is ignited. Therefore, the valve body typically also has an auxiliary switch for controlling the operation of these devices, which is triggered by rotating the valve stem.

[0003] In the existing technology, when gas control valves are manufactured and assembled, it is usually necessary to configure mounting brackets for the ignition switch and the associated switch separately. Therefore, two mounting brackets need to be manufactured and processed separately. During installation, the two mounting brackets are first installed onto the valve body, and then the ignition switch and the associated switch are installed onto their respective mounting brackets in sequence. The operation is relatively complicated and cumbersome, and the installation efficiency is low. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a gas control valve that facilitates the installation of the ignition switch and associated switches, thereby improving installation efficiency.

[0005] A gas control valve according to an embodiment of the present invention includes: a valve body with a valve stem movably mounted thereon, the valve stem having a central axis arranged in a vertical direction, the valve stem being movable along the central axis and rotatable around the central axis; a switch assembly including a mounting base, an ignition switch, and an associated switch, the mounting base having a first mounting position and a second mounting position arranged sequentially in a vertical direction, one of the ignition switch and the associated switch being mounted at the first mounting position and the other at the second mounting position, the associated switch having a first trigger part, the ignition switch having a second trigger part, the mounting base being detachably mounted on the outer wall of the valve body; and a pressing device including a first pressing member and a second pressing member disposed on the valve stem; when the mounting base is mounted on the outer wall of the valve body, the first trigger part and the second trigger part are both arranged towards the side close to the valve stem, the first pressing member being able to rotate with the valve stem to press against or separate from the first trigger part, and the second pressing member being able to move with the valve stem to press against or separate from the second trigger part.

[0007] In the gas control valve of this utility model embodiment, a mounting base is provided, which has a first mounting position and a second mounting position arranged sequentially in the vertical direction. Therefore, during installation, the associated switch and the ignition switch can be installed to their respective mounting positions to form a switch assembly first, and then the mounting base can be installed to the outer wall of the valve body, thereby completing the installation of the associated switch and the ignition switch. Compared with the prior art, which requires a separate mounting base for the associated switch and the ignition switch, the gas control valve of this utility model embodiment only requires the processing of one mounting base, reducing the number of parts that need to be processed and assembled. Moreover, during installation, the assembled switch assembly can be directly installed to the outer wall of the valve body, making installation more convenient and faster, which helps to shorten the assembly time of the gas control valve and improve the installation efficiency of the gas control valve.

[0039] Reference Figures 1 to 8 This utility model provides a gas control valve, including a valve body 100, a switch assembly 200, and a pressure device 300. A valve stem 110 is movably mounted on the valve body 100. The valve stem 110 has a central axis arranged in a vertical direction, and the valve stem 110 can move along and rotate around the central axis. The switch assembly 200 includes a mounting base 230, an ignition switch 220, and an associated switch 210. The mounting base 230 has a first mounting position 231 and a second mounting position 232 arranged sequentially in a vertical direction. One of the ignition switch 220 and the associated switch 210 is mounted at the first mounting position 231, and the other is mounted at the second mounting position 232. The associated switch 210 has a first trigger part 211, and the ignition switch 220 has a second trigger part 221. The mounting base 230 is detachably mounted on the outer wall of the valve body 100. The pressure device 300 includes a first pressure member 310 and a second pressure member 320 disposed on the valve stem 110. When the mounting base 230 is installed on the outer wall of the valve body 100, the first trigger part 211 and the second trigger part 221 are both arranged facing the side close to the valve stem 110. The first pressing member 310 can rotate with the valve stem 110 to press against or separate from the first trigger part 211. The second pressing member 320 can move with the valve stem 110 to press against or separate from the second trigger part 221.

[0040] In the gas control valve of this embodiment, a mounting base 230 is provided. The mounting base 230 has a first mounting position 231 and a second mounting position 232 arranged sequentially in the vertical direction. Therefore, during installation, the associated switch 210 and the ignition switch 220 can be installed to their respective mounting positions to form a switch assembly 200, and then the mounting base 230 can be installed to the outer wall of the valve body 100, thereby completing the installation of the associated switch 210 and the ignition switch 220. Compared with the prior art, which requires a separate mounting base 230 for each associated switch 210 and the ignition switch 220, the gas control valve of this embodiment only needs to be processed with one mounting base 230, reducing the number of parts that need to be processed and assembled. Moreover, during installation, the assembled switch assembly 200 can be directly installed to the outer wall of the valve body 100, making installation more convenient and faster, which helps to shorten the assembly time of the gas control valve and improve the installation efficiency of the gas control valve.

[0041] Understandably, when the mounting base 230 is installed on the outer wall of the valve body 100, the first trigger part 211 and the second trigger part 221 are both arranged towards the side close to the valve stem 110. The first pressing member 310 can rotate with the valve stem 110 to press against or separate from the first trigger part 211, thereby controlling the operation of the associated switch 210. The second pressing member 320 can move the valve stem 110 to rotate to press against or separate from the second trigger part 221, thereby controlling the operation of the ignition switch 220. Specifically, the valve body 100 has a valve cavity, and a valve core 130 connected to the valve stem 110 is provided in the valve cavity. The valve body 100 has a gas passage connected to the valve cavity. When the gas control valve of this embodiment is in use, the associated switch 210 can be electrically connected to the associated device, and the ignition switch 220 can be electrically connected to the ignition device. By pressing down the valve stem 110 and pushing the valve core 130 to open the gas passage, the second pressing member 320 moves down with the valve stem 110 and triggers the ignition switch 220 to connect the ignition device, thereby realizing gas ignition. Then, the valve stem 110 is rotated to adjust the gas flow. During this process, the first pressing member rotates with the valve stem 110 and triggers the associated switch 210 to connect the associated device, thereby controlling the associated device to start working after the gas is ignited and burned.

[0042] It is understood that the first pressing member 310 can rotate with the valve stem 110 to press against or separate from the first trigger part 211, thereby controlling the operation of the associated switch 210. The associated switch 210 can be configured such that when the first pressing member 310 presses against the first trigger part 211, the associated switch 210 connects to the associated device; when the first pressing member 310 separates from the first trigger part 211, the associated switch 210 disconnects from the associated device. Alternatively, the associated switch 210 can also be configured such that when the first pressing member 310 presses against the first trigger part 211, the associated switch 210 disconnects from the associated device; when the first pressing member 310 separates from the first trigger part 211, the associated switch 210 connects to the associated device. This utility model does not specifically limit the configuration in this way. Similarly, the second pressing member 320 can move the valve stem 110 to rotate to press against or separate from the second trigger part 221, thereby controlling the operation of the ignition switch 220. The ignition switch 220 can be configured such that when the second pressing member 320 presses against the second trigger part 221, the ignition switch 220 connects to the ignition device; and when the second pressing member 320 separates from the second trigger part 221, the ignition switch 220 disconnects from the ignition device. Alternatively, the ignition switch 220 can also be configured such that when the second pressing member 320 presses against the second trigger part 221, the associated switch 210 disconnects from the ignition device; and when the second pressing member 320 separates from the second trigger part 221, the ignition switch 220 connects to the ignition device. This invention does not specifically limit the specific configuration of this configuration.

[0043] It is understood that the associated devices may specifically be knobs, indicator lights, lighting fixtures, ventilation devices, etc., and this utility model does not specifically limit them.

[0044] Reference Figures 1 to 8 In some embodiments, the valve body 100 has an outwardly extending mounting platform 120 on its side wall, and a mounting base 230 is detachably mounted on the upper surface of the mounting platform 120. The mounting base 230 has a first side wall 260, and a first mounting position 231 and a second mounting position 232 are both formed in the first side wall 260, with a partition 240 between the first mounting position 231 and the second mounting position 232. An associated switch 210 is mounted in the first mounting position 231, and a first trigger portion 211 is located on the side of the associated switch 210 near the first side wall 260. An ignition switch 220 is mounted in the second mounting position 232, and a second trigger portion 221 is located on the side of the ignition switch 220 near the first side wall 260. When the mounting base 230 is mounted on the mounting platform 120, the first side wall 260 faces the valve stem 110.

[0045] By adopting the above structure, the mounting platform 120 facilitates the installation of the mounting base 230, making the installation between the mounting base 230 and the valve body 100 more convenient and the connection more secure and stable. Furthermore, by opening the first mounting position 231 and the second mounting position 232 on the first side wall 260, making the first mounting position 231 and the second mounting position 232 into mounting groove structures, it is not only convenient to limit and install the associated switch 210 and the ignition switch 220, but also convenient to shield and protect the associated switch 210 and the ignition switch 220, reducing external damage to the associated switch 210 and the ignition switch 220. In addition, when the mounting base 230 is installed on the mounting platform 120, the first side wall 260 faces the valve stem 110, thereby allowing the first trigger part 211 and the second trigger part 221 to both face the valve stem 110, thus facilitating the triggering of the associated switch 210 and the ignition switch 220 by the first pressing part and the second pressing member 320. By setting a partition 240 between the first mounting position 231 and the second mounting position 232, the ignition switch 220 and the associated switch 210 can be isolated from each other, thereby avoiding installation interference or short circuit between the ignition switch 220 and the associated switch 210, and thus improving the safety of the gas control valve.

[0046] Reference Figures 1 to 8 In some embodiments, the switch assembly 200 further includes two connection structures 290, each including a first connection portion 291 and a second connection portion 292. The first connection portion 291 passes through the associated switch 210 and the partition 240, and the second connection portion 292 passes through the base plate 250 of the ignition switch 220 and the second mounting position 232.

[0047] By adopting the above structure, the associated switch 210 is connected to the partition 240 through the first connecting part 291, and is thus installed in the first mounting position 231 of the mounting base 230. The ignition switch 220 is connected to the base plate 250 through the second connecting part 292, and is thus installed in the second mounting position 232 of the mounting base 230. The structure is simple and easy to install.

[0048] It is understandable that the number of the above-mentioned connection structures 290 is only two for... Figures 1 to 8 This is just one example. In addition, the number of connection structures 290 can also be one, three, four or more, and this utility model does not specifically limit the number of them.

[0049] Reference Figures 1 to 8 In some embodiments, the partition 240 has a first connecting hole 241 corresponding to the first connecting portion 291, and the bottom plate 250 has a second connecting hole 251 corresponding to the second connecting portion 292; wherein, the number of first connecting holes 241 and the number of second connecting holes 251 are the same and are arranged coaxially in a one-to-one correspondence; in the connecting structure 290, the first connecting portion 291 and the second connecting portion 292 are arranged coaxially and integrally connected.

[0050] By adopting the above structure, and by arranging the number of first connecting holes 241 and the number of second connecting holes 251 coaxially in a one-to-one correspondence, the first connecting part 291 and the second connecting part 292 can be integrally connected to form a whole part. This facilitates the production and processing of the connecting structure 290, and also reduces the number of parts to be assembled when installing the switch assembly 200. During installation, the entire connecting structure 290 only needs to be sequentially inserted into the associated switch 210, the partition 240, the ignition switch 220, and the base plate 250, which makes installation convenient and improves installation efficiency.

[0051] It is understood that the associated switch 210 has a first mounting hole (not shown in the figure) corresponding to the first connecting hole 241, and the ignition switch 220 has a second mounting hole (not shown in the figure) corresponding to the second connecting hole 251. Therefore, during installation, it is only necessary to place the associated switch 210 in the first mounting position 231 and align the first mounting hole with the corresponding first connecting hole 241, place the ignition switch 220 in the second mounting position 232 and align the second mounting hole with the corresponding second connecting hole 251, and then directly insert the connecting structure 290 through the coaxial first mounting hole, first connecting hole 241, second mounting hole, and second connecting hole 251 in sequence.

[0052] It is understood that in the connecting structure 290, the first connecting part 291 and the second connecting part 292 are arranged coaxially and connected integrally. Specifically, the connecting structure 290 can directly use bolts, screws, studs, etc., and this utility model does not make specific limitations in this regard.

[0053] Reference Figures 1 to 8 In some embodiments, the mounting platform 120 has a third connecting hole 121 corresponding to the second connecting hole 251. When the mounting base 230 is mounted on the mounting platform 120, the second connecting part 292 passes through the corresponding second mounting hole and the second connecting hole 251, and extends downward to pass through the corresponding third connecting hole 121.

[0054] By adopting the above structure, when the mounting base 230 is installed on the mounting platform 120, the second connecting part 292 can penetrate the base plate 250 and extend downward to pass through the mounting platform 120. Therefore, the mounting base 230 can be directly installed on the mounting platform 120 through the connecting structure 290. That is, the connecting structure 290 can be used to install the associated switch 210 and the ignition switch 220 to the mounting base 230 to form the switch assembly 200, and the connecting structure 290 can also be used to install the entire switch assembly 200 to the mounting platform 120. It has two uses and the structure is simple and easy to operate.

[0055] Understandably, when installing the switch assembly 200 onto the mounting platform 120, the connecting structure 290 can be sequentially passed through the coaxial first mounting hole, first connecting hole 241, second mounting hole, and second connecting hole 251, so that the associated switch 210 and ignition switch 220 are installed onto the mounting base 230 to form the switch assembly 200. Then, the switch assembly 200 is placed on the mounting platform 120, and the second connecting portion 292 of the connecting structure 290 is passed through the corresponding third connecting hole 121, thereby allowing the entire switch assembly 200 to be installed onto the mounting platform 120.

[0056] Reference Figures 1 to 8 In some embodiments, the bottom of the mounting base 230 is provided with a limiting groove 280 extending through the first side wall 260. The end of the limiting groove 280 away from the first side wall 260 is provided with a limiting part 281. When the mounting platform 120 is embedded in the limiting groove 280 and abuts against the limiting part 281, the third connecting hole 121 is aligned with the corresponding second connecting hole 251.

[0057] By adopting the above structure, when the mounting base 230 is installed on the mounting platform 120, the mounting base 230 can be placed on the upper surface of the mounting platform 120, so that the mounting platform 120 is embedded in the limiting groove 280, and the end of the mounting platform 120 away from the valve stem 110 abuts against the limiting part 281, thereby making the third connecting hole 121 of the base plate 250 correspondingly aligned with the third connecting hole 121 of the mounting platform 120. This makes it easy to insert the connecting structure 290 downward from the second connecting hole 251 into the corresponding third connecting hole 121. Therefore, the limiting groove 280 and the limiting part 281 can be used to position the mounting base 230 and the mounting platform 120, thereby facilitating the installation of the mounting base 230. At the same time, the limiting groove 280 and the limiting part 281 can also limit the mounting base 230 and the mounting platform 120, preventing misalignment of the mounting base 230 and the mounting platform 120 during the installation process, thus facilitating the smooth progress of the installation process.

[0058] Reference Figures 1 to 8 In some embodiments, the mounting base 230 further has a second sidewall 270 arranged opposite to the first sidewall 260. The associated switch 210 has three outwardly extending first terminals 212 located on the side of the associated switch 210 away from the first trigger portion 211. The second sidewall 270 has a first clearance groove 271 corresponding to the first terminals 212, which communicates with the first mounting position 231. The first terminals 212 can pass through the corresponding first clearance groove 271. The ignition switch 220 has two outwardly extending second terminals 222 located on the side of the ignition switch 220 away from the second trigger portion 221. The second sidewall 270 has a second clearance groove 272 corresponding to the second terminals 222, which communicates with the second mounting position 232. The second terminals 222 can pass through the corresponding second clearance groove 272.

[0059] By adopting the above structure, the second sidewall 270 can shield and protect the associated switch 210 and the ignition switch 220, reducing external damage to the associated switch 210 and the ignition switch 220. By providing a first clearance groove 271 corresponding to the first terminal 212 in the second sidewall 270, the first terminal 212 can pass through the first mounting position 231 for easy connection with associated devices. Furthermore, the first clearance groove 271 also provides a certain positioning and limiting function for the associated switch 210, facilitating its placement within the first mounting position 231. Similarly, by providing a second clearance groove 272 corresponding to the second terminal 222 in the second sidewall 270, the second terminal 222 can pass through the second mounting position 232 for easy connection with the ignition device. Furthermore, the second clearance groove 272 also provides a certain positioning and limiting function for the ignition switch 220, facilitating its placement within the first mounting position 231.

[0060] It is understandable that the aforementioned associated switch 210 has three outwardly extending first terminals 212, which are only for... Figures 1 to 8 As an example, the number of first terminals 212 is determined by the specific type and model of the selected associated switch 210. Depending on the type and model of the associated switch 210, the number of first terminals 212 can be three, one, two, four, or more; this utility model does not specifically limit this. Similarly, the ignition switch 220 described above has two outwardly extending second terminals 222, which is only for... Figures 1 to 8 As an example, the number of second terminals 222 is determined by the specific type and model of the selected ignition switch 220. Depending on the type and model of the ignition switch 220, the number of second terminals 222 can be two, one, three, four or more, and this utility model does not make a specific limitation in this regard.

[0061] Reference Figures 1 to 8 In some embodiments, the mounting base 230 is a one-piece molded structure.

[0062] By making the mounting base 230 a one-piece molded structure, the manufacturing of the mounting base 230 becomes more convenient and faster.

[0063] It is understandable that the mounting base 230 can be a one-piece injection molded structure.

[0064] Reference Figures 1 to 10In some embodiments, the first pressing member 310 and the second pressing member 320 are integral structures. Both the first pressing member 310 and the second pressing member 320 are sleeved on the valve stem 110 and can move and rotate with the valve stem 110. The outer peripheral wall of the first pressing member 310 includes an arc-shaped portion 311 and a flat portion 312 connected to each other. When the arc-shaped portion 311 rotates to face the first trigger portion 211, the arc-shaped portion 311 presses against the first trigger portion 211 and turns on the associated switch 210. When the flat portion 312 rotates to face the first trigger portion 211, the arc-shaped portion 311 presses against the first trigger portion 211 and turns on the associated switch 210. The first trigger part 211, the flat part 312 separates from the first trigger part 211 and closes the associated switch 210; the outer peripheral wall of the second pressing member 320 has a pressing surface 321, and the lower peripheral edge of the pressing surface 321 is connected to a guide surface 322 extending from top to bottom near the valve stem 110. When the second pressing member 320 moves downward with the valve stem 110, the guide surface 322 can abut against the second trigger part 221 and move downward relative to the second trigger part 221 until the pressing surface 321 presses against the second trigger part 221.

[0065] In the above structure, by setting the first pressing member 310 and the second pressing member 320 as an integral structure, it is convenient to install and assemble the pressing device 300 and the valve stem 110, reducing the number of parts that need to be assembled, which is beneficial to improving the assembly efficiency of the gas control valve.

[0066] By adopting the above-described structure of the first pressing member 310, the outer peripheral wall of the first pressing member 310 includes an interconnected arc-shaped portion 311 and a flat portion 312, so that the projection of the outer peripheral wall of the first pressing member 310 in the vertical direction is "D" shaped. When the valve stem 110 is rotated, the first pressing member 310 can rotate with the valve stem 110. When the first pressing member 310 rotates to the point where the arc-shaped portion 311 faces the associated switch 210, the arc-shaped portion 311 can abut against the first trigger portion 211 to open the associated switch 210, thus connecting the associated switch 210 with the associated device. When the flat portion 312 rotates to face the first trigger portion 211, the flat portion 312 separates from the first trigger portion 211 and closes the associated switch 210, thus breaking the circuit between the associated switch 210 and the associated device. Thus, the control of the associated device can be realized. The structure is simple and the operation is convenient.

[0067] By adopting the above-described structure of the second pressing member 320, the outer peripheral wall of the second pressing member 320 has a pressing surface 321. The lower peripheral edge of the pressing surface 321 is connected to a guide surface 322 extending from top to bottom near the valve stem 110. When the second pressing member 320 moves downward with the valve stem 110, the guide surface 322 can play a guiding role, guiding the second pressing member 320 to move downward until the pressing surface 321 abuts against the second trigger part 221 of the ignition switch 220, thereby triggering the ignition switch 220, so that the ignition switch 220 is connected to the ignition device to realize ignition. When the second pressing member 320 moves upward until the pressing surface 321 is away from the second trigger part 221, the ignition switch 220 can be turned off, thus breaking the circuit between the ignition switch 220 and the ignition device.

[0068] An embodiment of this utility model also proposes a gas appliance, which is provided with a gas control valve of any of the above embodiments.

[0069] In the gas appliance of this utility model embodiment, by adopting the gas control valve of any embodiment, the gas control valve is provided with a mounting base 230. The mounting base 230 is provided with a first mounting position 231 and a second mounting position 232 arranged sequentially in the vertical direction. During installation, the associated switch 210 and the ignition switch 220 can be installed to the corresponding mounting positions to form a switch assembly 200, and then the mounting base 230 can be installed to the outer wall of the valve body 100, thereby completing the installation of the associated switch 210 and the ignition switch 220. Compared to the prior art, which requires separate mounting bases 230 for the associated switch 210 and the ignition switch 220, this gas control valve only requires the machining of one mounting base 230, reducing the number of parts that need to be machined and assembled. Furthermore, mounting the associated switch 210 and the ignition switch 220 onto the same mounting base 230 makes the structure of the gas control valve more compact, which in turn helps to improve the structural stability of the gas appliance. During installation, the assembled switch assembly 200 can be directly installed onto the outer wall of the valve body 100, making installation more convenient and quick, thereby shortening the assembly time of the gas appliance and improving the installation efficiency of the gas appliance.

[0070] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
