This allows the primary air supply volume of the gas stove using the damper plate of this application to be adjustable. An elastic fastener can clamp the gas distribution pipe. The elastic force of the elastic fastener itself allows it to fix the gas distribution pipe. Since the elastic fastener is mounted on the fixed plate, the gas distribution pipe and the fixed plate can be tightly connected.

[0012] In some embodiments, the air distribution pipe includes a pipe body and a boss, the boss being sleeved on the pipe body, the boss being located inside the air intake and abutting against the elastic fastener, so that the elastic fastener limits the boss in the direction from the first end to the second end.

[0013] In some embodiments, the air intake includes a first air intake section and a second air intake section connected to each other, the inner diameter of the first air intake section being smaller than that of the second air intake section to form a first stepped surface within the air intake, and the boss abutting against the first stepped surface to limit the boss in the direction from the second end to the first end.

[0014] In some embodiments, the air intake further includes a third air intake section connected to the end of the first air intake section facing away from the second air intake section. The inner diameter of the third air intake section is smaller than that of the first air intake section to form a second stepped surface within the air intake. The end of the air distribution pipe abuts against the second stepped surface.

[0015] In some embodiments, the damper plate further includes a sealing element, which is sleeved on the pipe body, with one side of the sealing element abutting against the first stepped surface and the other side of the sealing element abutting against the boss.

[0041] This application is described below with reference to the accompanying drawings and specific embodiments:

[0042] Example 1

[0043] Please refer to Figures 1-3This application discloses an air damper, including a fixed plate 100, a movable plate 200 and an elastic fastener 300, which can be applied to a gas stove.

[0044] It should be understood that the damper plate is a component in the gas stove used to regulate the amount of primary air supplied. The damper plate is located at the air inlet end of the injector tube 700 of the gas stove. The damper plate can have an air inlet that connects to the nozzle 500 of the gas stove, as well as an air inlet for allowing outside air to enter. The nozzle 500 can input fuel gas into the injector tube 700 through the air inlet of the damper plate. During this process, outside air can enter the injector tube 700 as primary air through the air inlet of the damper plate, allowing the air and fuel gas to mix within the injector tube 700. The size of the air inlet of the damper plate is adjustable, thus allowing for adjustment of the amount of primary air entering the injector tube 700 through the air inlet of the damper plate.

[0045] The fixing plate 100 is the basic component of the damper plate of this application. The fixing plate 100 can provide an installation base for at least some other components of the damper plate of this application. The fixing plate 100 can be fixedly installed on the air inlet end of the gas stove's injector tube 700. The fixing plate 100 is opposite to a part of the air inlet end of the injector tube 700, thereby causing the fixing plate 100 to be misaligned with another part of the air inlet end of the injector tube 700. This results in a gap between a part of the edge of the fixing plate 100 and the air inlet end of the injector tube 700, which can form the air inlet of the injector tube 700. The fixed plate 100 also has an air intake 130, which is a channel that runs through the fixed plate 100. The air intake 130 has a first end and a second end, which are opposite ends of the air intake 130. The first end of the air intake 130 is connected to the nozzle 500, and the nozzle 500 is connected to the ejector tube 700. The second end of the air intake 130 is connected to the gas distribution pipe 400. This allows the fuel gas to be sequentially input into the ejector tube 700 through the gas distribution pipe 400, the air intake 130 of the fixed plate 100, and the nozzle 500.

[0046] The movable plate 200 is movably disposed on one side of the fixed plate 100. Specifically, the movable plate 200 can rotate relative to the fixed plate 100. The movable plate 200 can rotate until it is opposite to the fixed plate 100. In this way, primary air can be fully introduced into the injector tube 700 through the air inlet to supplement the gas stove with primary air and to maximize the amount of primary air introduced into the injector tube 700.

[0047] When the movable plate 200 rotates to a position where at least a portion of the movable plate 200 is misaligned with the fixed plate 100, at least a portion of the air inlet of the ejector tube 700 is blocked by the movable plate 200. This reduces the opening area of ​​the air inlet of the ejector tube 700, and consequently reduces the amount of primary air entering the ejector tube 700. During the rotation of the movable plate 200 relative to the fixed plate 100, the area of ​​the misaligned portion is adjustable, thereby adjusting the opening area of ​​the air inlet of the ejector tube 700 and, consequently, the amount of primary air entering the ejector tube 700. Therefore, the user can adjust the movable plate 200 according to the actual combustion effect of the gas stove to achieve the optimal combustion effect of the fuel gas.

[0048] The fixing plate 100 provides a mounting base for the elastic fixing member 300, allowing the elastic fixing member 300 to be mounted on the fixing plate 100. Since the fixing plate 100 is fixedly mounted on the ejector tube 700, the elastic fixing member 300 remains stable. The elastic fixing member 300 clamps the air distribution pipe 400, ensuring its stability. Specifically, the elastic fixing member 300 clamps and fixes the air distribution pipe 400, securing it to the fixing member 300. Because the elastic fixing member 300 is fixed to the fixing plate 100, the air distribution pipe 400 is also fixed to the fixing plate 100. This makes the connection between the air distribution pipe 400 and the second end of the air intake duct 130 more stable and reliable, preventing the air distribution pipe 400 from detaching from the fixing plate 100. The elastic fastener 300 clamps the gas distribution pipe 400 with elastic force, making it easy to assemble and disassemble the elastic fastener 300 and the gas distribution pipe 400. In specific operation, the user can press the elastic fastener 300 to clamp the gas distribution pipe 400, and then release the elastic fastener 300 to clamp the gas distribution pipe 400 tightly to prevent the gas distribution pipe 400 from separating and falling off from the fixing plate 100.

[0049] In the damper plate proposed in this embodiment, the movable plate 200 is rotatably disposed on the fixed plate 100. The movable plate 200 can at least partially block the fixed plate 100, making the size of the air opening formed between the fixed plate 100 and the ejector tube 700 adjustable, thereby making the primary air supply of the gas stove using the damper plate of this application adjustable. The elastic fastener 300 can clamp the gas distribution pipe 400. The elastic force of the elastic fastener 300 itself can fix the gas distribution pipe 400. Since the elastic fastener 300 is disposed on the fixed plate 100, the gas distribution pipe 400 can be tightly connected to the fixed plate 100. The elastic fastener 300 and the gas distribution pipe 400 are easy to assemble and disassemble, making it easy to assemble and disassemble the gas distribution pipe 400 and the fixed plate 100.

[0050] In some implementations, reference Figures 3-5To ensure the elastic fastener 300 is fixedly mounted on the fixing plate 100, the fixing plate 100 may have a slot 121. The slot 121 of the fixing plate 100 may be located on the side wall of the fixing plate 100 and communicate with the air intake duct 130. One end of the air distribution pipe 400 connected to the fixing plate 100 may pass through the second end of the air intake duct 130 and extend into the air intake duct 130, specifically through the slot 121 of the fixing plate 100. In this way, the elastic fastener 300 can pass through the slot 121 of the fixing plate 100 and extend into the air intake duct 130 to clamp the air distribution pipe 400, thereby achieving the purpose of fixing the air distribution pipe 400. Specifically, the end of the elastic fastener 300 used to clamp the gas distribution pipe 400 can pass through the slot 121 of the fixing plate 100, so that the inner wall of the slot 121 can limit the elastic fastener 300, thereby locking the elastic fastener 300 into the slot 121 of the fixing plate 100. The width of the slot 121 of the fixing plate 100 can be specifically set to match the size of the elastic fastener 300, so that the elastic fastener 300 can abut against the opposite side walls of the slot 121 in the width direction, thereby allowing the slot 121 of the fixing plate 100 to further limit the elastic fastener 300.

[0051] refer to Figure 7 The elastic fastener 300 specifically includes a first clamping portion 310 and a second clamping portion 320. One end of the first clamping portion 310 is elastically connected to one end of the second clamping portion 320. Correspondingly, the other ends of the first clamping portion 310 and the second clamping portion 320 form a clamping opening. The gas distribution pipe 400 can extend into the space between the first clamping portion 310 and the second clamping portion 320 through the clamping opening of the elastic fastener 300. Under the drive of the mutual elastic force, the first clamping portion 310 and the second clamping portion 320 can tightly clamp the gas distribution pipe 400. Therefore, when the elastic fastener 300 is disposed in the slot 121 of the fixing plate 100, both the first clamping portion 310 and the second clamping portion 320 can abut against the inner wall of the slot 121 of the fixing plate 100, so that the elastic fastener 300 clamps the gas distribution pipe 400 more effectively.

[0052] Of course, the length of the slot 121 of the fixing plate 100 can also be set to match the size of the elastic fastener 300. When the elastic fastener 300 passes through the slot 121 of the fixing plate 100, each inner sidewall of the slot 121 of the fixing plate 100 can abut against the elastic fastener 300, thereby making the effect of fixing the elastic fastener 300 in the slot 121 of the fixing plate 100 more reliable.

[0053] In other embodiments, refer to Figure 1In this application, the two ends of the first clamping portion 310 of the elastic fastener 300 and the two ends of the second clamping portion 320 can be connected respectively, so that the elastic fastener 300 is a closed structure without openings. The elastic fastener 300 is an integrally elastic and extensible structural component. The elastic fastener 300 can be embedded in the slot 121 of the fixing plate 100 and clamp the air distribution pipe 400. When the air distribution pipe 400 needs to be separated from the fixing plate 100, the clamping opening of the elastic fastener 300 can be enlarged and the elastic fastener 300 can be clamped to other parts of the fixing plate 100.

[0054] In some implementations, reference Figure 4 To further improve the connection reliability between the elastic fastener 300 and the fixed plate 100, the fixed plate 100 can have two slots 121. These two slots 121 can be located on opposite sides of the fixed plate 100. Therefore, when the air distribution pipe 400 extends into the air intake duct 130 of the fixed plate 100, the two slots 121 are located on opposite sides of the air distribution pipe 400. The first clamping part 310 of the elastic fastener 300 can extend into one of the two slots 121, and the second clamping part 320 can extend into the other slot 121. Thus, the first clamping part 310 and the second clamping part 320 can be fixed in the two slots 121 of the fixed plate 100, respectively.

[0055] Specifically, the two slots 121 of the fixing plate 100 are spaced apart, so that the side wall of the fixing plate 100 has a supporting side wall 122 between the two slots 121. The first clamping part 310 and the second clamping part 320 are elastically connected, so that the elastic force between the first clamping part 310 and the second clamping part 320 can drive the first clamping part 310 and the second clamping part 320 to tightly abut against the opposite sides of the supporting side wall 122, thereby generating friction between the first clamping part 310 and the second clamping part 320 and the supporting side wall 122. This friction can further make the elastic fixing member 300 stably and reliably set in the slot 121 to clamp the gas distribution pipe 400.

[0056] Of course, in other embodiments, when the number of slots 121 in the fixing plate 100 is one, the first clamping portion 310 and the second clamping portion 320 of the elastic fixing member 300 can be inserted into the slot 121 and extend into the air intake duct 130 of the fixing plate 100 to clamp the air distribution pipe 400. The inner wall of the slot 121 of the fixing plate 100 can support and abut against the first clamping portion 310 and the second clamping portion 320 so that the elastic fixing member 300 can be fixed to the fixing plate 100.

[0057] In some implementations, reference Figure 6The gas distribution pipe 400 in this application specifically includes a pipe body 410 and a boss 420. The pipe body 410 is the basic component of the gas distribution pipe 400. One end of the pipe body 410 is connected to the nozzle 500 of the gas stove, and the other end of the pipe body 410 is connected to the gas distribution pipe 400 of the gas stove. The boss 420 is a ring-shaped structural component, which is sleeved on the pipe body 410, so that the outer wall of the pipe body 410 has a raised structure. When the elastic fastener 300 is clamped in the pipe body 410, the elastic fastener 300 can abut against the boss 420. In this way, the boss 420 can limit the elastic fastener 300 and the pipe body 410 to each other in the axial direction of the pipe body 410, so as to further fix the gas distribution pipe 400 in the air inlet 130 of the fixing plate 100. Specifically, when the elastic fastener 300 clamps the air distribution pipe 400, both the first clamping part 310 and the second clamping part 320 can abut against the boss 420. When the air distribution pipe 400 is subjected to external force, causing the air distribution pipe 400 to tend to separate from the fixed plate 100, the boss 420 and the elastic fastener 300 can cooperate to snap the air distribution pipe 400 into the air inlet 130 of the fixed plate 100.

[0058] It should be understood that when the air distribution pipe 400 passes through the air intake duct 130 of the fixed plate 100, the air distribution pipe 400 extends into the air intake duct 130 from the second end of the air intake duct 130. If the air distribution pipe 400 needs to be separated from the air intake duct 130, it should be moved in the direction from the first end to the second end. When the elastic fastener 300 abuts against the boss 420, the boss 420 can be located on the side of the elastic fastener 300 facing the first end. That is, the elastic fastener 300 can limit the boss 420 in the direction from the first end to the second end of the air intake duct 130, thereby limiting the air distribution pipe 400 to prevent the air distribution pipe 400 from falling out and separating from the air intake duct 130 of the fixed plate 100.

[0059] In addition, in other embodiments, the number of protrusions 420 in this application can also be set to two. The two protrusions 420 can be spaced apart and sleeved on the tube body 410. The elastic fastener 300 can be clamped on the tube body 410 and located between the two protrusions 420, so that the two opposite sides of the first clamping part 310 and the two opposite sides of the second clamping part 320 can respectively abut against the two protrusions 420. In this way, the elastic fastener 300 can limit the tube body 410 in the direction from the second end to the first end and from the first end to the second end, thereby making the gas distribution pipe 400 more stable. The distance between the two protrusions 420 can be matched with the dimensions of the first clamping part 310 and the second clamping part 320, so that the opposite sides of the first clamping part 310 and the opposite sides of the second clamping part 320 can be in contact with the inner walls of the two protrusions 420 or maintain a small distance. When the opposite sides of the first clamping part 310 and the opposite sides of the second clamping part 320 are in contact with the inner walls of the two protrusions 420, the air distribution pipe 400 can be further stabilized in the axial direction of the pipe body 410. When the opposite sides of the first clamping part 310 and the opposite sides of the second clamping part 320 have a small gap with the inner walls of the two protrusions 420, the air distribution pipe 400 can be relatively stable in the axial direction of the pipe body 410, and it is easier for the elastic fastener 300 to clamp the pipe body 410 at the part located between the two protrusions 420.

[0060] In some implementations, reference Figure 5 In order to keep the air distribution pipe 400 stable in its axial direction, a first step surface 134 corresponding to the boss 420 can be provided in the air intake passage 130 of the fixed plate 100, so that the first step surface 134 in the air intake passage 130 can limit the boss 420. Specifically, the air intake 130 of the fixed plate 100 can be configured to include a first air intake section 131 and a second air intake section 132, wherein the first air intake section 131 is connected to the second air intake section 132, and the inner diameter of the second air intake section 132 is larger than the inner diameter of the first air intake section 131, so that a first step surface 134 can be formed between the first air intake section 131 and the second air intake section 132. The first step surface 134 between the first air intake section 131 and the second air intake section 132 is located on the side of the boss 420 facing away from the second end of the air intake 130, so that the first step surface 134 between the first air intake section 131 and the second air intake section 132 can limit the air distribution pipe 400 in the direction from the second end to the first end, thereby cooperating with the elastic fixing member 300 to limit the air distribution pipe 400 in the direction from the first end to the second end of the air intake 130, so that the air distribution pipe 400 can remain stable in two opposite directions in its axial direction.

[0061] When the boss 420 abuts against the first stepped surface 134 inside the intake duct 130, the side of the pipe body 410 located at the first end of the boss 420 facing the intake duct 130 can extend into the first air passage section 131, so that the connection between the pipe body 410 and the intake duct 130 is more reliable. Specifically, the inner diameter of the first air passage section 131 can be set to match the outer diameter of the part of the pipe body 410 located at the first end of the boss 420 facing the intake duct 130, so that this part of the pipe body 410 can be relatively tightly inserted into the first air passage section 131, thereby allowing the gas in the pipe body 410 to flow fully into the intake duct 130, preventing gas leakage between the gas distribution pipe 400 and the intake duct 130.

[0062] In some implementations, reference Figure 5 In order to further stabilize the air distribution pipe 400, a second step surface 135 corresponding to the end of the air distribution pipe 400 can be provided in the air intake 130 of the fixed plate 100, so that the second step surface 135 in the air intake 130 can mutually limit the end of the air distribution pipe 400. Specifically, the air intake 130 of the fixed plate 100 may also include a third air intake section 133, wherein the third air intake section 133 is connected to the end of the first air intake section 131 facing away from the second air intake section 132, and the inner diameter of the first air intake section 131 is larger than the inner diameter of the third air intake section 133, so that a second step surface 135 can be formed between the first air intake section 131 and the third air intake section 133. The second step surface 135 can limit the air distribution pipe 400 in the direction from the second end to the first end, thereby cooperating with the elastic fixing member 300 to limit the air distribution pipe 400 in the direction from the first end to the second end of the air intake 130, so that the air distribution pipe 400 can remain stable in two opposite directions in its axial direction.

[0063] In some implementations, reference Figure 3The damper plate of this application also includes a sealing element 600, wherein the sealing element 600 can be sleeved on the pipe body 410 of the gas distribution pipe 400, and the sealing element 600 is located between the boss 420 and the first stepped surface 134 of the air intake duct 130. In this way, one side of the sealing element 600 can abut against the boss 420, and the other side of the sealing element 600 can abut against the first stepped surface 134, so that the sealing element 600 is sandwiched between the boss 420 and the first stepped surface 134. The sealing element 600 is specifically a ring structure, and the inner diameter of the sealing element 600 matches the outer diameter of the pipe body 410, so that the sealing element 600 and the pipe body 410 are tightly connected. In this way, the sealing element 600 can block the opening of the gap between the pipe body 410 and the first air passage section 131 of the air intake duct 130, preventing gas from leaking from the gap between the first air passage section 131 and the pipe body 410. Furthermore, it should be understood that the seal 600 may also be configured to have a certain degree of elasticity, such as by using an elastic material to make the seal 600 elastic, or by designing the structure of the seal 600 to make the seal 600 elastic. This application does not impose any limitations on this. When the boss 420 abuts against the seal 600, the seal 600 can undergo a certain deformation. In this way, the restoring deformation force of the seal 600 can act on the boss 420, so that the boss 420 can abut tightly against the elastic fixing member 300. This makes the mutual limiting effect between the elastic fixing member 300 and the boss 420 better, so that the air distribution pipe 400 is more stably installed in the air intake duct 130 of the fixed plate 100.

[0064] In some implementations, reference Figure 4 The fixing plate 100 of this application can be specifically configured to include a first plate body 110 and a connecting pipe section 120, wherein the connecting pipe section is connected to the first plate body 110, the first air passage section 131 and the second air passage section 132 of the fixing plate 100 are located inside the connecting pipe section 120, and the third air passage section 133 is located in the first plate body 110 and penetrates through the first plate body 110. The first plate body 110 can be a relatively thin plate component, and the connecting pipe section 120 is a tubular structural component, wherein the first plate body 110 is a structural component in the damper plate that cooperates with the movable plate 200, and the first plate body 110 can be disposed inside the ejector tube 700. The outer wall of the first plate body 110 and the inner wall of the ejector tube 700 have a gap, which constitutes the air port of the ejector tube 700. Primary air can be supplied into the ejector tube 700 from the air port, and the air distribution pipe 400 is connected to the connecting pipe section 120. The connecting pipe 120 can be connected to the side of the first plate 110 facing away from the ejector tube 700, so that the connecting pipe 120 can be located outside the ejector tube 700, thereby making it easier to fix and install the gas distribution pipe 400 to the connecting pipe 120.

[0065] It should be understood that the connecting pipe section 120 is used to set the first air passage section 131 and the second air passage section 132. The connecting pipe section 120 can only be used to allow gas to pass through, and the connecting pipe section 120 has no mating relationship with the ejector tube 700. Therefore, the outer diameter of the connecting pipe section 120 can be set to be relatively small, so that the overall volume of the fixing plate 100 is relatively small and less material is used, so as to achieve the purpose of making the damper plate of this application compact and reducing the manufacturing cost. Specifically, the connecting pipe section 120 can be connected to the center of the first plate body 110, so that the gas can enter the central area of ​​the ejector tube 700 and then diffuse around the ejector tube 700, thereby making the gas and air in the ejector tube 700 mix more thoroughly.

[0066] In some implementations, reference Figure 3 When the damper plate of this application is installed on a gas stove, the nozzle 500 of the gas stove is specifically connected to the third gas passage section 133 of the fixing plate 100. In order to make the connection between the nozzle 500 and the fixing plate 100 more reliable and stable, at least a portion of the nozzle 500 can extend into the third gas passage section 133, so that the air inlet end of the nozzle 500 can be located in the third gas passage section 133, so that gas can enter into the nozzle 500. The outer diameter of the nozzle 500 can match the inner diameter of the third gas passage section 133, so that the outer wall of the nozzle 500 fits against the inner wall of the third gas passage section 133. In this way, the third gas passage section 133 can limit and fix the nozzle 500, so that the nozzle 500 can be stably and reliably fixed in the third gas passage section 133, and at the same time, it can prevent gas from leaking from the third gas passage section 133 and the nozzle 500, thus ensuring the safety of the gas stove using the damper plate of this application. The outer wall of the nozzle 500 and the inner wall of the third air passage section 133 can be provided with corresponding threads, so that the nozzle 500 and the third air passage section 133 can be connected by thread engagement.

[0067] In some implementations, reference Figure 1 , Figure 4 and Figure 9To enable the fixing plate 100 of this application to be fixed to the ejector tube 700, a notch 710 may be provided at the end of the ejector tube 700 for mounting the fixing plate 100. A protrusion 140 corresponding to the notch 710 of the ejector tube 700 may be provided on the fixing plate 100. The protrusion 140 may be fitted into the notch 710 of the ejector tube 700, thus fixing the fixing plate 100 to the end of the ejector tube 700. The ejector tube 700 may have multiple notches 710, and correspondingly, multiple protrusions 140 may also be provided, each fitted into a different notch 710 of the ejector tube 700. Corresponding positioning holes may also be provided on the notch 710 and the protrusions 140 of the ejector tube 700. Positioning elements may be installed into these positioning holes to ensure that the fixing plate 100 and the ejector tube 700 are stably and reliably fixed together. Therefore, when the fixing plate 100 is installed with the ejector tube 700, the fixing plate 100 can be pre-positioned by the cooperation of the notch 710 and the protrusion 140 of the ejector tube 700, and then the fixing member is installed in the fixing hole, so that the fixing plate 100 and the ejector tube 700 can be installed conveniently.

[0068] In some implementations, reference Figure 8 The movable plate 200 of this application may specifically include a second plate body 210 and a sleeve 220, wherein the sleeve 220 is connected to the second plate body 210, the second plate body 210 is sleeved on the connecting pipe portion 120, and the sleeve 220 is also sleeved on the connecting pipe portion 120. This allows the contact area between the movable plate 200 and the fixed plate 100 to be larger, so that the connection between the movable plate 200 and the fixed plate 100 is more reliable.

[0069] Example 2

[0070] Based on the damper plate described above, this application also proposes a gas stove, including the damper plate, gas distribution pipe 400 and nozzle 500 described above. The damper plate can be installed at the end of the injector pipe 700 of the gas stove and connected to the gas distribution pipe 400 to control the amount of primary air entering the injector pipe 700.

[0071] In some embodiments, the gas stove of this application may have two injector tubes 700, and therefore two damper plates and two gas distribution pipes 400. The two gas distribution pipes 400 supply gas to the two injector tubes 700 respectively, and the two damper plates control the primary air supply to the two injector tubes 700 respectively. The two injector tubes 700 may be connected to the internal combustion gas passage and the external combustion gas passage of the gas stove respectively, so that the gas stove can form a stable inner ring flame and an outer ring flame.
