Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0048] 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.

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.

[0049] The first aspect of this application discloses a gas flow regulating device 100, which, in some embodiments, is combined with Figure 1 and Figure 8As shown, the gas flow regulating device 100 includes a base 1000, a first solenoid valve 2100, and a second solenoid valve 2200. The first solenoid valve 2100 is disposed on the base 1000 to control the gas flow, and the second solenoid valve 2200 is disposed on the base 1000 to control the gas flow. The valve core 2110 of the first solenoid valve 2100 reciprocates along the axis 2120 of the first solenoid valve 2100, which is arranged laterally. The valve core 2210 of the second solenoid valve 2200 reciprocates along the axis 2220 of the second solenoid valve 2200, which is also arranged laterally. By arranging the axes 2120 of the first solenoid valve 2100 and 2220 of the second solenoid valve 2200 laterally, the space occupied by the gas flow regulating device 100 in the vertical direction can be reduced, which contributes to the slim design of the gas stove.

[0050] Specifically, the base 1000 serves as the supporting frame for the gas flow regulating device 100. Most of the other components of the gas flow regulating device 100, except for the base 1000, can be mounted on the base 1000. When installing the gas flow regulating device 100 into the target area, the installation is achieved by connecting and fixing the base 1000 to the target area. The base 1000 can be a one-piece molded structure or a split structure connected and fixed by a connecting means. The base 1000 can be made of at least one of metal, plastic, or other materials; for example, the base 1000 can be made of cast iron. The base 1000 is provided with corresponding gas passages. Gas flows into and out of the interior of the base 1000. The flow rate of the gas through the base 1000 is controlled by the first solenoid valve 2100 and the second solenoid valve 2200.

[0051] The first solenoid valve 2100 and the second solenoid valve 2200 are electrically powered components, laying the foundation for the intelligent / automatic operation of the gas flow regulating device 100. Based on the program design, the first solenoid valve 2100 and the second solenoid valve 2200 can perform corresponding actions, thereby keeping the corresponding gas passage of the base 1000 in an open or closed state. Gas can only flow through the corresponding gas passage when it is open, and cannot flow through it when it is closed, thus achieving gas flow regulation. It can be understood that the so-called program can be understood as the control logic that enables the current device to operate normally. The program can be set according to actual needs, which is not the inventive point of this application and will not be elaborated on here.

[0052] In this embodiment, the first solenoid valve 2100 and the second solenoid valve 2200 are disposed on the base 1000. There are multiple ways to connect the first solenoid valve 2100 and the base 1000, and the second solenoid valve 2200 and the base 1000. As long as the first solenoid valve 2100 and the base 1000 can be connected and fixed together, and the second solenoid valve 2200 and the base 1000 can be connected and fixed together, the common connection method is screw connection. When the first solenoid valve 2100 and the second solenoid valve 2200 are installed on the base 1000, the axis 2120 of the first solenoid valve 2100 is arranged laterally, and the axis 2220 of the second solenoid valve 2200 is also arranged laterally. Lateral can be understood as a roughly horizontal direction. The reciprocating movement direction of the valve core 2110 of the first solenoid valve 2100 is the extension direction of its axis 2120, and the reciprocating movement direction of the valve core 2210 of the second solenoid valve 2200 is the extension direction of its axis 2220. The orientations in this article are based on the assumption that the gas flow regulating device 100 is installed on the gas stove, and the gas stove is installed in the usage environment. Figure 1 The axis 2120 of the first solenoid valve 2100 is arranged laterally and extends in the front-to-back direction, and the axis 2220 of the second solenoid valve 2200 is also arranged laterally and extends in the front-to-back direction. By arranging the axes 2120 and 2220 of the first solenoid valve 2100 and the second solenoid valve 2200 laterally, the first solenoid valve 2100 and the second solenoid valve 2200 are arranged laterally as a whole, which reduces the space occupied in the vertical direction. When the gas flow regulating device 100 is installed on the gas stove, it helps to make the gas stove thinner.

[0053] In some embodiments, combined with Figure 1 As shown, when projected onto the horizontal plane along the vertical direction, the minimum distance between the projections of the first solenoid valve 2100 and the second solenoid valve 2200 is 0, and the lowest point of one of the first solenoid valve 2100 and the second solenoid valve 2200 is not higher than the highest point of the other. The projections of the first solenoid valve 2100 and the second solenoid valve 2200 can be exactly touching, or they can be alternately arranged. This ensures that the first solenoid valve 2100 and the second solenoid valve 2200 do not overlap at least partially along the vertical direction on the base 1000. Furthermore, by ensuring that the lowest point of one of the first solenoid valve 2100 and the second solenoid valve 2200 is not higher than the highest point of the other, it helps to further reduce the space occupied in the vertical direction.

[0054] In some embodiments, combined with Figure 1As shown, the axis 2120 of the first solenoid valve 2100 and the axis 2220 of the second solenoid valve 2200 are located on the same horizontal plane. This arrangement of the axes 2120 and 2220 at the same height helps reduce the space occupied in the vertical direction. Optionally, the axes 2120 and 2220 of the first solenoid valve 2100 and the second solenoid valve 2200 can be parallel or form an angle.

[0055] In some embodiments, combined with Figure 1 As shown, the first solenoid valve 2100 and the second solenoid valve 2200 are located on the same side of the base 1000. For example, when the base 1000 is installed on a gas stove, the base 1000 has a front side, a rear side, a left side, and a right side. The first solenoid valve 2100 and the second solenoid valve 2200 are both installed on the front side, the rear side, the left side, or the right side of the base 1000, which makes it easier to wire the first solenoid valve 2100 and the second solenoid valve 2200.

[0056] In some embodiments, combined with Figure 1 As shown, the opposite sides of the first solenoid valve 2100 are connected by fasteners 4100 and base 1000 respectively, and the line connecting the opposite sides of the first solenoid valve 2100 extends in the vertical direction.

[0057] Specifically, the fastener 4100 can be a screw, and the first solenoid valve 2100 has corresponding fastening holes 4200 on its opposite sides. The base 1000 also has fastening holes 4200 corresponding to the first solenoid valve 2100. The opposite sides of the first solenoid valve 2100 are connected and fixed to the base 1000 by screws. Since the first solenoid valve 2100 and the second solenoid valve 2200 are located on the same side of the base 1000, and the line connecting the opposite sides of the first solenoid valve 2100 extends in the vertical direction, this helps to reduce the lateral space occupied by the first solenoid valve 2100.

[0058] Similarly, the opposite sides of the second solenoid valve 2200 are connected by fasteners 4100 and base 1000 respectively, and the line connecting the opposite sides of the second solenoid valve 2200 extends in the vertical direction. When the first solenoid valve 2100 and the second solenoid valve 2200 are arranged side by side in the lateral direction, the aforementioned improvement helps to reduce the lateral space occupied by the gas flow regulating device 100.

[0059] For example Figure 1 The axis 2120 of the first solenoid valve 2100 and the axis 2220 of the second solenoid valve 2200 extend in the front-to-back direction. The line connecting the opposite sides of the first solenoid valve 2100 and the line connecting the opposite sides of the second solenoid valve 2200 extend in the vertical direction. By setting it in this way, the space occupied in the left-to-right direction can be reduced.

[0060] In some embodiments, combined with Figure 8 As shown, the first solenoid valve 2100 is located on one side of the base 1000, and the second solenoid valve 2200 is located on the other side of the base 1000. For example, when the base 1000 is installed on a gas stove, the base 1000 has a front, rear, left, and right side. The first solenoid valve 2100 is installed on the front side, and the second solenoid valve 2200 is installed on the left, right, or rear side; or the first solenoid valve 2100 is installed on the rear side, and the second solenoid valve 2200 is installed on the front, left, or right side. Many other cases are not listed here. This arrangement helps to make full use of space.

[0061] For example, the first solenoid valve 2100 and the second solenoid valve 2200 are located on opposite sides of the base 1000. This could mean the first solenoid valve 2100 is located on the front side of the base 1000 and the second solenoid valve 2200 is located on the rear side of the base 1000, or the first solenoid valve 2100 is located on the rear side of the base 1000 and the second solenoid valve 2200 is located on the front side of the base 1000, or the first solenoid valve 2100 is located on the left side of the base 1000 and the second solenoid valve 2200 is located on the right side of the base 1000, or the first solenoid valve 2100 is located on the right side of the base 1000 and the second solenoid valve 2200 is located on the left side of the base 1000. This helps to compress the dimensions between the other opposite sides of the base 1000.

[0062] In some embodiments, the opposite sides of the first solenoid valve 2100 are connected to the base 1000 via fasteners 4100 and fasteners 4100, respectively. The line connecting the opposite sides of the first solenoid valve 2100 extends laterally and is perpendicular to the axis 2120 of the first solenoid valve 2100, which facilitates further flattening of the design. Similarly, the opposite sides of the second solenoid valve 2200 are connected to the base 1000 via fasteners 4100 and fasteners 4100, respectively. The line connecting the opposite sides of the second solenoid valve 2200 extends laterally and is perpendicular to the axis 2220 of the second solenoid valve 2200. For example... Figure 8 The axis 2120 of the first solenoid valve 2100 and the axis 2220 of the second solenoid valve 2200 extend in the front-to-back direction, and the line connecting the opposite sides of the first solenoid valve 2100 and the line connecting the opposite sides of the second solenoid valve 2200 extend in the left-to-right direction. This arrangement helps to achieve a flat design.

[0063] In some embodiments, combined with Figures 1 to 3 as well as Figures 8 to 10As shown, the base 1000 is provided with an air inlet channel 1100, an air outlet channel 1200, and an auxiliary channel 1300. A first solenoid valve 2100 is adapted to open and close the air outlet channel 1200. When the first solenoid valve 2100 opens the air outlet channel 1200, the air outlet channel 1200 and the air inlet channel 1100 are connected. A second solenoid valve 2200 is adapted to open and close the auxiliary channel 1300. When the second solenoid valve 2200 opens the auxiliary channel 1300 and the first solenoid valve 2100 opens the air outlet channel 1200, the air outlet channel 1200 and the air inlet channel 1100 are connected, and the air outlet channel 1200 and the auxiliary channel 1300 are connected. The auxiliary channel 1300 and the air inlet channel 1100 are also connected.

[0064] The base 1000 is provided with an air inlet channel 1100, an air outlet channel 1200, and an auxiliary channel 1300, which constitute the gas path mentioned above. In this embodiment, the base 1000 is a one-piece molded structure. The air inlet channel 1100, air outlet channel 1200, and auxiliary channel 1300 are formed by machining. The air inlet channel 1100 is used to receive gas, and the air outlet channel 1200 is used to discharge gas. For example, the air inlet channel 1100 is connected to a gas source, which includes, but is not limited to, bottled liquefied petroleum gas or piped natural gas. The gas supplied by the gas source is input into the interior of the base 1000 through the air inlet channel 1100 and discharged from the air outlet channel 1200, and finally input into the burner head. The gas is ejected from the burner head's flame holes and ignited to form a flame.

[0065] The gas needs to enter the interior of the base 1000 and be discharged from the gas outlet channel 1200 through the cooperation of the first solenoid valve 2100 and the gas outlet channel 1200, and the cooperation of the second solenoid valve 2200 and the auxiliary channel 1300.

[0066] The first solenoid valve 2100 can open and close the gas outlet passage 1200; that is, the first solenoid valve 2100 has the function of opening and closing the gas outlet passage 1200. When the first solenoid valve 2100 opens the gas outlet passage 1200, the gas can enter the interior of the base 1000 from the inlet passage 1100 and flow through the gas outlet passage 1200 before being discharged from it. When the first solenoid valve 2100 closes the gas outlet passage 1200, the gas cannot flow through the gas outlet passage 1200 and cannot be discharged from it.

[0067] The second solenoid valve 2200 can open and close the auxiliary channel 1300, meaning it has both the function of opening and closing the auxiliary channel 1300. When the first solenoid valve 2100 opens the outlet channel 1200 and the second solenoid valve 2200 opens the auxiliary channel 1300, the gas can enter the interior of the base 1000 from the inlet channel 1100. The gas can either flow from the inlet channel 1100 through the outlet channel 1200 to be discharged, or it can flow from the inlet channel 1100 through the auxiliary channel 1300 and then through the outlet channel 1200 to be discharged. Compared to relying solely on the first solenoid valve 2100 to open the outlet channel 1200, the gas flow rate entering the outlet channel 1200 increases in this case. When the first solenoid valve 2100 closes the gas outlet passage 1200, or when the first solenoid valve 2100 closes the gas outlet passage 1200 and the second solenoid valve 2200 closes the gas outlet passage 1200, the gas cannot enter the gas outlet passage 1200, that is, no gas is discharged from the gas outlet passage 1200 at this time.

[0068] Therefore, when the first solenoid valve 2100 opens the gas outlet channel 1200 and the second solenoid valve 2200 closes the auxiliary channel 1300, the gas flow regulating device 100 can output the minimum gas flow rate. When the first solenoid valve 2100 opens the gas outlet channel 1200 and the second solenoid valve 2200 opens the auxiliary channel 1300, the gas flow regulating device 100 can output the maximum gas flow rate. When applied to a gas stove, the actions of the first solenoid valve 2100 and the second solenoid valve 2200 can be automatically controlled based on the temperature measured by the probe, thereby achieving precise temperature control and realizing intelligent cooking.

[0069] In some embodiments, combined with Figures 1 to 13 As shown, the base 1000 is also provided with an air passage 1400. One end of the air passage 1400 is adapted to be connected to the air inlet passage 1100, and the other end of the air passage 1400 is adapted to be connected to the air outlet passage 1200. The auxiliary passage 1300 is adapted to be connected in parallel with the air passage 1400.

[0070] When the first solenoid valve 2100 opens the outlet passage 1200, the gas enters the interior of the base 1000 from the inlet passage 1100 and flows to the outlet passage 1200 through the outlet passage 1400, and then exits from the outlet passage 1200. When the first solenoid valve 2100 opens the outlet passage 1200 and the second solenoid valve 2200 opens the auxiliary passage 1300, the gas enters from the inlet passage 1100, one path of gas flows to the outlet passage 1200 through the outlet passage 1400, and the other path of gas flows to the outlet passage 1200 through the auxiliary passage 1300. Both paths of gas are then exited through the outlet passage 1200.

[0071] In some embodiments, combined with Figure 1 , Figures 5 to 7, Figures 8 to 13 As shown, the gas flow regulating device 100 also includes an adjusting component 3000, which is connected to the base 1000 and is suitable for adjusting the opening of the gas passage 1400. The gas flow can be calibrated by adjusting the adjusting component 3000.

[0072] It is understandable that different regions have different gas source types and product loads. To adapt to more usage scenarios, this embodiment also includes an adjuster 3000. The adjuster 3000 is connected to the base 1000 and is used to adjust the opening of the gas passage 1400. Changing the opening size can correspondingly change the gas flow rate / pressure, thus adapting to more usage scenarios. The adjuster 3000 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 adjuster 3000 again. Of course, whether to adjust it can be determined by professionals.

[0073] Optionally, in some embodiments, the adjusting member 3000 is rotatably mounted on the base 1000 to adjust the opening of the air passage 1400. The adjusting member 3000 adjusts the opening of the air passage 1400 by rotation, which helps improve reliability. For example, the adjusting member 3000 and the base 1000 are threaded together; that is, the adjusting member 3000 has external threads (which can be understood as the adjusting member 3000 being a screw), and the base 1000 has internal threads. The engagement of the external and internal threads allows the adjusting member 3000 to rotate. This threaded connection makes it less likely for the adjusting member 3000 to rotate under accidental force, ensuring the stability of the opening of the air passage 1400.

[0074] In some embodiments, the regulating member 3000 is adapted to change the cross-sectional area of ​​the gas passage 1400 to adjust the opening of the gas passage 1400. For example, the gas passage 1400 includes an intersecting and connected upstream passage 1410 and downstream passage 1420. The upstream passage 1410 is connected to the inlet passage 1100, and the downstream passage 1420 is connected to the outlet passage 1200. The regulating member 3000 is rotatably disposed in the upstream passage 1410. By rotating the regulating member 3000, the cross-sectional area of ​​the flow path formed by the upstream passage 1410 and the downstream passage 1420 can be changed, thereby adjusting the gas flow rate. Alternatively, the upstream passage 1410 may have a stepped surface; the smaller the distance between the regulating member 3000 and the stepped surface, the smaller the gas flow rate; the larger the distance between the regulating member 3000 and the stepped surface, the larger the gas flow rate. Alternatively, the regulating member 3000 may rotate to adjust the degree of obstruction to the downstream passage 1420, thereby adjusting the gas flow rate.

[0075] Combination Figure 2 , Figure 3 , Figure 4 , Figure 9 and Figure 10 As shown, in some embodiments, the air outlet channel 1200 is provided with a first connection port 1210, and the first solenoid valve 2100 is adapted to block the first connection port 1210 to close the air outlet channel 1200, and is adapted to disengage from the first connection port 1210 to open the air outlet channel 1200.

[0076] When the first solenoid valve 2100 blocks the first connecting port 1210, it closes the gas outlet passage 1200. When the first solenoid valve 2100 disengages from the first connecting port 1210, it opens the gas outlet passage 1200. By setting the first connecting port 1210 in conjunction with the first solenoid valve 2100, the opening and closing of the gas outlet passage 1200 can be easily achieved. When the first solenoid valve 2100 disengages from the first connecting port 1210, the gas flows in from the inlet passage 1100 and enters the gas outlet passage 1200 through the first connecting port 1210, and is then discharged.

[0077] It is understandable that the first solenoid valve 2100 blocks and disengages from the first connecting port 1210 through the movement of its valve core 2110. The valve core 2110 of the first solenoid valve 2100 reciprocates along the axis 2120 of the first solenoid valve 2100. When the valve core 2110 of the first solenoid valve 2100 moves towards the first connecting port 1210, it can abut against the first connecting port 1210 to block the first connecting port 1210, thus closing the air outlet passage 1200. When the valve core 2110 of the first solenoid valve 2100 moves away from (away from) the first connecting port 1210, it can disengage from the first connecting port 1210, thus opening the air outlet passage 1200. It is understandable that when the valve core 2110 of the first solenoid valve 2100 blocks the first connecting port 1210, it can close the first connecting port 1210 by abutting against the periphery of the first connecting port 1210.

[0078] Optionally, the valve core 2110 of the first solenoid valve 2100 is provided with a first sealing gasket 2111, and the valve core 2110 of the first solenoid valve 2100 is adapted to seal the first connection port 1210 through the first sealing gasket 2111. The first sealing gasket 2111 can be made of a flexible material, including but not limited to rubber, silicone, etc. When sealing the first connection port 1210, the first sealing gasket 2111 elastically deforms, improving the sealing performance of the first connection port 1210 and preventing gas leakage when sealing the first connection port 1210.

[0079] Similarly, the auxiliary channel 1300 is provided with a second connection port 1310. The second solenoid valve 2200 is adapted to block the second connection port 1310 to close the auxiliary channel 1300, and is also adapted to disengage from the second connection port 1310 to open the auxiliary channel 1300. When the second solenoid valve 2200 blocks the second connection port 1310, the auxiliary channel 1300 is closed; when the second solenoid valve 2200 disengages from the second connection port 1310, the auxiliary channel 1300 is opened. By providing the second connection port 1310 in conjunction with the second solenoid valve 2200, the opening and closing of the auxiliary channel 1300 can be easily achieved. When the second solenoid valve 2200 disengages from the second connection port 1310, the gas flows in from the intake channel 1100 and enters the auxiliary channel 1300 through the second connection port 1310, and then flows to the outlet channel 1200.

[0080] The second solenoid valve 2200 blocks and disconnects from the second communication port 1310 through the movement of its valve core 2210. The valve core 2210 of the second solenoid valve 2200 reciprocates along its axis 2220. When the valve core 2210 moves toward the second communication port 1310, it abuts against the second communication port 1310 to block it, thus closing the auxiliary channel 1300. When the valve core 2210 moves away from (away from) the second communication port 1310, it disconnects from it, thus opening the auxiliary channel 1300. The valve core 2210 of the second solenoid valve 2200 is also provided with a second sealing gasket 2211, which blocks the second communication port 1310.

[0081] In some embodiments, combined with Figure 2 , Figure 3 , Figure 9 and Figure 10 As shown, the base 1000 is provided with a first receiving cavity 1510, an air passage 1400 is connected to the first receiving cavity 1510, an auxiliary passage 1300 is connected to the first receiving cavity 1510, and a first solenoid valve 2100 is installed in the first receiving cavity 1510. The first solenoid valve 2100 is adapted to allow the air outlet passage 1200 to connect to the first receiving cavity 1510 through the first connecting port 1210 when it is disconnected from the first connecting port 1210.

[0082] The configuration of the first receiving cavity 1510 lays the foundation for the installation of the first solenoid valve 2100. For example, one end of the first receiving cavity 1510 is open, the first solenoid valve 2100 is installed at the open end of the first receiving cavity 1510 and is connected and fixed to the base 1000. The valve core 2110 of the first solenoid valve 2100 is movable in the first receiving cavity 1510, thereby blocking and disconnecting from the first communication port 1210.

[0083] When the first solenoid valve 2100 disengages from the first connection port 1210, the gas can enter from the intake channel 1100 and flow through the gas channel 1400 into the first receiving cavity 1510, and then enter the outlet channel 1200 through the first connection port 1210, and thus be discharged from the outlet channel 1200.

[0084] Similarly, the base 1000 is provided with a second receiving cavity 1520, and the second solenoid valve 2200 is installed in the second receiving cavity 1520. The second solenoid valve 2200 is adapted to allow the auxiliary channel 1300 to connect with the air intake channel 1100 through the second connecting port 1310 when it is disconnected from the second connecting port 1310.

[0085] The configuration of the second receiving cavity 1520 lays the foundation for the installation of the second solenoid valve 2200. For example, one end of the second receiving cavity 1520 is open, the second solenoid valve 2200 is installed to the open end of the second receiving cavity 1520 and is connected and fixed to the base 1000. The valve core 2210 of the second solenoid valve 2200 is movable in the second receiving cavity 1520, thereby blocking and disengaging from the second communication port 1310.

[0086] When the first solenoid valve 2100 opens the first connection port 1210 and the second solenoid valve 2200 opens the second connection port 1310, the gas can enter the base 1000 from the inlet channel 1100. One gas path enters the first receiving cavity 1510 through the gas passage 1400 and then enters the outlet channel 1200 through the first connection port 1210. The other gas path enters the second receiving cavity 1520 and then enters the auxiliary channel 1300 through the second connection port 1310 and then enters the first receiving cavity 1510. Finally, it enters the outlet channel 1200 through the first connection port 1210.

[0087] The first solenoid valve 2100 has a fast response speed and a high degree of automation, which is beneficial for realizing automated control. Optionally, the first solenoid valve 2100 is a bistable solenoid valve, which is more energy-efficient and has lower power consumption. It can be battery-driven to meet the needs of home installation scenarios. It can be understood that solenoid valves include monostable solenoid valves and bistable solenoid valves. Monostable solenoid valves require continuous power to change their state. For example, when a monostable solenoid valve is de-energized, it relies on spring force to keep the first connection port 1210 closed. When energized, electromagnetic force overcomes the spring force to open the first connection port 1210. Bistable solenoid valves, on the other hand, can be de-energized after a brief change of state to maintain the current state. Therefore, bistable solenoid valves have lower power consumption. Similarly, the second solenoid valve 2200 is a bistable solenoid valve.

[0088] This application also discloses a gas stove, which in some embodiments combines... Figures 1 to 13As shown, the gas stove includes the aforementioned gas flow regulating device 100. The gas flow regulating device 100 includes a base 1000, a first solenoid valve 2100, and a second solenoid valve 2200. The first solenoid valve 2100 is disposed on the base 1000 to control the gas flow, and the second solenoid valve 2200 is disposed on the base 1000 to control the gas flow. The valve core 2110 of the first solenoid valve 2100 reciprocates along its axis 2120, which is laterally arranged. The valve core 2210 of the second solenoid valve 2200 reciprocates along its axis 2220, which is also laterally arranged. By laterally arranging the axes 2120 and 2220 of the first and second solenoid valves, the space occupied by the gas flow regulating device 100 in the vertical direction can be reduced, contributing to a slimmer design for the gas stove. It is understood that the gas flow regulating device 100 of the gas stove in this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought about by the technical solution of the above embodiment, which will not be repeated here.

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.
