Description

Technical Field

[0001] This invention relates to the field of home appliance technology, specifically to a damper adjustment device and a gas stove. Background Technology

[0002] In existing gas stove air damper adjustment devices, an integrated handle design is commonly used. Users need to first lift the handle to disengage the air damper, then adjust its position, and finally adjust the opening of the gas damper and air damper according to the preset fixing holes on the fixing plate. However, for ordinary users, the above operation process is complicated and lacks intuitiveness. Users are very likely to overlook the crucial step of "lifting the air damper" during use, thus failing to effectively adjust the air damper, significantly affecting the user experience and cooking results. Summary of the Invention

[0003] In view of this, the present invention provides an air damper adjustment device and a gas stove to solve the problems of the lack of intuitive operation, low success rate and ineffective adjustment of the air damper in the prior art.

[0004] In a first aspect, the present invention provides a damper adjustment device, comprising:

[0005] Fixing plate; The air regulating vane is rotatably mounted on one side of the fixed vane; The handle is plugged into the air regulator and has a locking position that is inserted into the air regulator to a first depth and an unlocking position that is pulled out to a second depth, the second depth being less than the first depth. When the handle is in the locked position, the handle and the fixed plate are engaged in the upper limit of the circumferential direction to lock the air regulating plate and the fixed plate. When the handle is in the unlocked position, the handle is disengaged from the fixed plate, and the handle can drive the air regulating plate to rotate relative to the fixed plate under the action of external force.

[0006] Beneficial Effects: This application innovatively adopts a separate structural design for the handle and the air regulator vane. The handle is connected to the air regulator vane via a plug-in method. The air regulator vane and the fixing plate are locked and unlocked through a direct plug-in operation of the handle: "insert to lock, pull out to unlock." This completely eliminates the counterintuitive step of "requiring the air regulator vane to be lifted first" in traditional designs, making the damper adjustment process more intuitive and simplified, with a high success rate. Users only need three steps to complete the stepless damper adjustment: "pull out - adjust - push back." There is no need to read the instruction manual or understand complex steps; operation can be completed intuitively, reducing operational difficulty and significantly improving user intuitiveness and success rate. This solves the problem of users easily overlooking the crucial step of "lifting the air regulator vane first," thus failing to effectively adjust the damper. Furthermore, the different insertion and removal depths distinguish the locked and unlocked positions, providing clear operational feedback and a better user experience.

[0007] In one optional embodiment, the air regulating plate has a plug-in groove for mounting a handle, and the plug-in groove has a first limiting groove at a first depth and a second limiting groove at a second depth. The handle includes a handle body and an elastic limiting structure disposed on the handle body. The elastic limiting structure can retract into the handle body or extend out of the handle body under its own elastic force. When the handle is inserted into the first depth of the insertion slot, the elastic limiting structure extends out of the handle body and is limited in the first limiting groove; when the handle is pulled out to the second depth of the insertion slot, the elastic limiting structure extends out of the handle body and is limited in the second limiting groove.

[0008] Beneficial effects: The design of the first and second limiting grooves enables precise positioning and self-locking of the handle in two working positions. The elastic limiting structure provides reliable holding force, ensuring that the handle will not accidentally shift due to its own weight or slight external force in both locked and unlocked states, thus improving the reliability and safety of the device. Furthermore, the cooperation between the elastic limiting structure and the first and second limiting grooves provides a clear "click" sensation when the user pulls out the handle for adjustment or pushes it back to lock, offering positive tactile feedback and allowing the user to clearly perceive whether the operation is in place, thus enhancing the user experience.

[0009] In one optional implementation, the elastic limiting structure includes: The first elastic element has a mounting groove on the handle body for mounting the first elastic element. A limiting member is provided at the end of the first elastic member. The limiting member can retract into the mounting groove under the action of external pressure. When the pressure disappears, the limiting member can extend out under the action of the first elastic member and be limited in the first limiting groove or the second limiting groove.

[0010] Beneficial effects: By integrating the limiting member and the first elastic member inside the handle body, the structure is compact and does not increase the volume of the components. The limiting member can retract smoothly when squeezed and pop out quickly under the action of the first elastic member after the external force is removed, ensuring smooth insertion and removal operations and rapid positioning response.

[0011] In one alternative embodiment, the mounting groove is a transverse through-groove that passes through the two opposite side walls of the handle body, and the first elastic element is placed transversely in the mounting groove. There are two limiting members, which are disposed at both ends of the first elastic member. The first limiting groove and the second limiting groove are each provided with two corresponding grooves.

[0012] Beneficial effects: The design of the horizontal first elastic element and the symmetrical limiting elements on both sides ensures that the handle is subjected to balanced force during insertion and removal, avoiding jamming or wear problems that may be caused by force on one side, and improving the stability and service life of the structure.

[0013] In one alternative implementation, the first elastic element is a spring; And / or, the limiting element is a limiting block, and the limiting block is provided with a guide slope, which is used to guide the limiting block to slide into the first limiting groove or the second limiting groove; And / or, the corners of the first and second limiting grooves are both rounded.

[0014] Beneficial effects: Using a spring as the primary elastic element is reliable, cost-effective, easy to procure and mass-produce, ensuring consistent product quality. The guide slope on the limiting component and the rounded corners at the first and second limiting grooves significantly reduce the impact and frictional resistance when the limiting component contacts the edges of the two limiting grooves. This makes the insertion and removal of the handle easier and smoother, reduces wear on parts, extends the device's lifespan, and improves operational comfort.

[0015] In one alternative embodiment, a second elastic element is provided between the handle and the air deflector, the second elastic element being used to apply a thrust to the handle to move it in the pulling direction.

[0016] Beneficial effects: The preload of the second elastic element ensures the handle remains stably in the locked position. Specifically, when the handle is pulled out and pushed back into the locked position after adjustment, the limiting element automatically pops out and embeds into the first limiting groove under the synergistic action of the second and first elastic elements, achieving stable locking of the damper opening and preventing the limiting element from dislodging from the first limiting groove due to handle wobbling. This application achieves rapid compression, pop-out, and automatic fixing of the handle through the linkage mechanism of the retractable limiting elements on both sides of the plug end at the lower end of the handle, ensuring a stable and reliable adjustment process without the need for additional reset operations.

[0017] In one alternative embodiment, the fixing plate is provided with a slide rail groove, and the handle is provided with a sliding protrusion. When the handle drives the air regulating plate to rotate relative to the fixed plate under the action of external force, the sliding convex plate slides along the slide rail groove.

[0018] Beneficial effects: By allowing the sliding convex plate to slide continuously within the arc-shaped slide rail groove, the fan fin can be infinitely slid to any setting, breaking through the limitations of traditional fixed-position discrete settings. Users can adjust the damper to any opening within the allowable range of the slide rail groove, achieving true stepless adjustment and precisely adapting to diverse cooking needs, from slow simmering to high-heat braising. Furthermore, the slide rail groove precisely guides and constrains the movement path of the sliding convex plate, ensuring smooth rotation of the fan fin and preventing wobbling.

[0019] In one alternative embodiment, the slide rail groove is arc-shaped, and the slide rail groove has a first arc-shaped side and a second arc-shaped side disposed opposite to each other; The first arc-shaped edge is located on the side closer to the center of the fixing piece, and the second arc-shaped edge is located on the side farther from the center of the fixing piece. When the handle is in the locked position, the sliding convex plate is engaged and fixed to the first arc-shaped edge.

[0020] Beneficial effects: When the handle is in the locked position, the sliding convex plate is engaged and fixed to the first arc-shaped edge, which not only effectively fixes the air regulating plate and the fixed plate, but also makes separation convenient without the need for external tools. Furthermore, the air regulating plate adopts the aforementioned slide rail groove design; the first and second arc-shaped edges limit the insertion and removal depth of the handle, ensuring an appropriate insertion and removal depth and achieving precise positioning of the handle's up and down movement. This ensures that the elastic limiting structure is firmly embedded in the first or second limiting groove and stably fixed, guaranteeing the stability and accuracy of the adjustment process.

[0021] In one optional embodiment, a plurality of positioning protrusions are evenly spaced on the first arc-shaped edge; Two locking edges are provided at intervals on the side of the sliding protrusion near the first arc edge, and the two locking edges can be locked between at least two adjacent positioning protrusions.

[0022] Beneficial effects: Multiple positioning protrusions evenly distributed on the first arc-shaped edge allow for precise positioning and locking of the handle, providing users with tactile feedback on gear levels without compromising stepless adjustment accuracy. Furthermore, the two locking edges can engage with any two, three, or four adjacent positioning protrusions, effectively securing the handle, air intake, and fixing plate.

[0023] In one alternative embodiment, the handle includes a handle body and a grip portion, the grip portion being fixedly disposed at the end of the handle body away from the air regulating plate, and the grip portion being provided with anti-slip grooves.

[0024] Beneficial effects: The grip design facilitates user operation of the handle, and the anti-slip grooves significantly increase the friction between the fingers and the handle, ensuring stable operation even with wet or oily hands, effectively preventing slippage and improving operational safety. This also enhances the comfort of the grip.

[0025] Secondly, the present invention also provides a gas stove, including the damper adjustment device of any of the above embodiments. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] In related technologies, gas stove damper adjustment devices generally employ an integrated handle design. Users must first lift the handle horizontally to disengage the air intake plate, then adjust its position, adjusting the gas damper and air damper opening according to the pre-set holes on the mounting plate. However, this operation process lacks intuitiveness for ordinary users. Product manuals often fail to clearly explain the crucial step of "lifting the air intake plate horizontally," leading users to easily overlook this step and thus fail to effectively adjust the damper. Furthermore, the limited number of mounting holes on the mounting plate restricts airflow adjustment to discrete levels, failing to meet users' needs for continuous stepless adjustment and making it difficult to precisely adapt to diverse cooking scenarios such as simmering over low heat, stir-frying over medium heat, or high heat cooking. Moreover, because the damper adjustment is installed inside the gas stove casing, users cannot observe the specific settings during operation, increasing the risk of errors such as misalignment with the desired setting and adding to the operational difficulty. Existing damper adjustment devices not only result in high operational barriers and low adjustment efficiency but also significantly impact user experience and cooking results. Therefore, there is an urgent need for a damper adjustment device that is easy to operate and allows for stepless adjustment, in order to solve the problems of high operating threshold and insufficient adjustment accuracy in the existing technology.

[0034] The following is combined with Figures 1 to 11 The following describes embodiments of the present invention.

[0035] According to an embodiment of the present invention, in one aspect, the present invention provides a damper adjustment device, including a fixed plate 1, an air regulating plate 2, and a handle 3. The air regulating plate 2 is rotatably disposed on one side of the fixed plate 1. The handle 3 is pluggably connected to the air regulating plate 2. The handle 3 has a locking position that is inserted into the air regulating plate 2 to a first depth and an unlocking position that is pulled out into the air regulating plate 2 to a second depth. The second depth is less than the first depth. The handle 3 moves between the locking position and the unlocking position. When the handle 3 is in the locking position, the handle 3 and the fixed plate 1 are engaged in a circumferential upper limit engagement to lock the air regulating plate 2 and the fixed plate 1. When the handle 3 is in the unlocking position, the handle 3 is disengaged from the fixed plate 1, and the handle 3 can drive the air regulating plate 2 to rotate relative to the fixed plate 1 under the action of an external force.

[0036] In the above embodiment, an innovative separate design is adopted for the handle 3 and the air regulating vane 2. The handle 3 is connected to the air regulating vane 2 by a plug-in method. The air regulating vane 2 and the fixing plate 1 are locked and unlocked by the direct plug-in operation of the handle 3, which completely eliminates the counterintuitive step of "lifting the air regulating vane 2 first" in the traditional design. This makes the damper adjustment operation process more intuitive and simplified, with a high success rate. During adjustment, the user only needs to complete the stepless damper adjustment in three steps: "pull out - adjust - push back". There is no need to read the instruction manual to understand the complicated steps. The operation can be completed intuitively, reducing the difficulty of operation and significantly improving the intuitiveness and success rate of user operation. It solves the problem that the user is unable to effectively adjust the damper because they easily overlook the key step of "lifting the air regulating vane 2 first" due to their operating habits. In addition, the different insertion and removal depths distinguish the locked and unlocked positions, providing clear operation feedback to the user and improving the operation experience.

[0037] Specifically, the fixed plate 1 and the air regulating plate 2 are respectively provided with air holes. When the air holes on the fixed plate 1 and the air regulating plate 2 are completely misaligned, the damper adjustment device is closed and the air volume is zero. When the air holes on the fixed plate 1 and the air regulating plate 2 are completely aligned, the air volume of the damper adjustment device is at its maximum. The handle 3 is plugged into and connected to the outer periphery of the air regulating plate 2. The extension direction of the handle 3 is consistent with the radial direction of the air regulating plate 2. When the handle 3 is in the locked position, the handle 3 and the fixed plate 1 are in a circumferential upper limit engagement, thereby achieving reliable fixation of the air regulating plate 2 and the fixed plate 1, preventing gear changes due to accidental touch or vibration, and ensuring the stability of the cooking process. When the handle 3 is in the unlocked position, the handle 3 and the fixed plate 1 are disengaged from the upper limit engagement, the air regulating plate 2 and the fixed plate 1 are unlocked, and the handle 3 can drive the air regulating plate 2 to rotate relative to the fixed plate 1 under the action of external force, thereby adjusting the air volume.

[0038] In one optional embodiment, the air deflector 2 has a insertion slot 21 for mounting the handle 3. The insertion slot 21 has a first limiting groove 22 at a first depth and a second limiting groove 23 at a second depth. The handle 3 includes a handle body 31 and an elastic limiting structure 32 disposed on the handle body 31. The elastic limiting structure 32 can retract into the handle body 31 or extend out of the handle body 31 under its own elastic force. When the handle 3 is inserted into the insertion slot 21 to the first depth, the elastic limiting structure 32 extends out of the handle body 31 and is limited within the first limiting groove 22. When the handle 3 is pulled out to the insertion slot 21 to the second depth, the elastic limiting structure 32 extends out of the handle body 31 and is limited within the second limiting groove 23.

[0039] In the above embodiment, the design of the first limiting groove 22 and the second limiting groove 23 enables precise positioning and self-locking of the handle 3 in two working positions. The elastic limiting structure 32 provides a reliable holding force, ensuring that the handle 3 will not accidentally shift due to its own weight or slight external force in both locked and unlocked states, thus improving the reliability and safety of the device. Furthermore, the cooperation between the elastic limiting structure 32 and the first and second limiting grooves 22 and 23 provides a clear "click" sensation when the user pulls out the handle 3 for adjustment or pushes it back to lock, providing positive tactile feedback and allowing the user to clearly perceive whether the operation is in place, thus improving the user experience.

[0040] Based on the above embodiments, as a further defined embodiment, the insertion groove 21 is formed radially on the outer peripheral wall of the air regulating plate 2, and the first limiting groove 22 and the second limiting groove 23 are groove structures formed on the groove wall of the insertion groove 21. The second limiting groove 23 is close to the groove opening side of the insertion groove 21, and the first limiting groove 22 is far away from the groove opening side of the insertion groove 21.

[0041] As an alternative implementation, the elastic limiting structure 32 can be a button spring, a ball spring structure, a torsion spring driven pawl structure, or an elastic plastic latch structure. Preferably, in this embodiment, the elastic limiting structure 32 is a button spring, which can achieve a better balance between reliability, cost and feel.

[0042] In one optional embodiment, the elastic limiting structure 32 includes a first elastic element 321 and a limiting element 322. The handle body 31 is provided with a mounting groove 30 for mounting the first elastic element 321. The limiting element 322 is disposed at the end of the first elastic element 321. The limiting element 322 can retract into the mounting groove 30 under the action of external pressure. When the pressure disappears, the limiting element 322 can extend out under the action of the first elastic element 321 and be limited in the first limiting groove 22 or the second limiting groove 23.

[0043] In the above embodiments, by integrating the limiting member 322 and the first elastic member 321 inside the handle body 31, the structure is compact and does not increase the volume of the components. The limiting member 322 can smoothly retract when squeezed and quickly pop out under the action of the first elastic member 321 after the external force disappears, ensuring smooth insertion and removal operations and rapid positioning response.

[0044] Based on the above embodiments, as a further defined embodiment, the first elastic member 321 is limited within the mounting groove 30, and the limiting member 322 is fixedly connected to or abuts against the first elastic member 321. The first elastic member 321 can be a spring, torsion spring, leaf spring, or an elastomer such as rubber or polyurethane. The limiting member 322 can be a spherical limiting member 322 (such as a steel ball). The spherical limiting member 322 slides extremely smoothly into and out of the limiting groove, with low frictional resistance, which can greatly improve the smoothness of operation. Alternatively, the limiting member 322 can also be a wedge-shaped or inclined limiting member 322. The limiting member 322 can also be a plastic part, which is lightweight and produces less impact noise. This embodiment does not specifically limit this aspect.

[0045] In one optional embodiment, the mounting groove 30 is a transverse through groove passing through the two opposite side walls of the handle body 31, and the first elastic member 321 is horizontally placed in the mounting groove 30; there are two limiting members 322, which are disposed at both ends of the first elastic member 321, and two first limiting grooves 22 and two second limiting grooves 23 are provided respectively; the two limiting members 322 can retract into the mounting groove 30 under the action of external pressure, or extend out under the action of the first elastic member 321 and be limited in the two sets of first limiting grooves 22 or two sets of second limiting grooves 23.

[0046] In the above embodiments, the design of the horizontally placed first elastic element 321 and the symmetrical limiting elements 322 on both sides ensures that the handle 3 is subjected to balanced force during insertion and removal, avoiding jamming or wear problems that may be caused by force on one side, and improving the stability and service life of the structure.

[0047] Specifically, the insertion slot 21 has a first slot wall and a second slot wall arranged opposite to each other. Two first limiting grooves 22 are symmetrically opened on the first slot wall and the second slot wall, and two second limiting grooves 23 are symmetrically opened on the first slot wall and the second slot wall. The second limiting grooves 23 are located above the first limiting grooves 22. The first limiting grooves 22 are close to the bottom of the insertion slot 21, and the second limiting grooves 23 are close to the opening of the insertion slot 21. It should be noted that in this embodiment, the opening of the insertion slot 21 is located on the outer peripheral wall of the air regulating plate 2.

[0048] In one optional embodiment, the first elastic element 321 is a spring; the limiting element 322 is a limiting block, and the limiting block is provided with a guide slope, which is used to guide the limiting block to slide into the first limiting groove 22 or the second limiting groove 23; the corners of the first limiting groove 22 and the second limiting groove 23 are both rounded.

[0049] In the above embodiment, a spring is used as the first elastic element 321, which is reliable, inexpensive, easy to procure and mass-produce, and ensures the consistency of product quality. By providing a guide slope on the limiting element 322 and rounding the corners at the corners of the first limiting groove 22 and the second limiting groove 23, the impact and frictional resistance when the limiting element 322 contacts the edges of the two limiting grooves are greatly reduced, making the insertion and removal operation of the handle 3 more effortless and smoother, which helps to reduce the wear of parts, extend the life of the device, and improve the comfort of the operating feel.

[0050] Specifically, the limiting member 322 includes a limiting block body, the longitudinal section of which is an isosceles trapezoid, and the transverse cross-sectional area of ​​the limiting block body gradually decreases from the bottom side to the top side. The two sides of the isosceles trapezoid form a guide slope. The upper base of the isosceles trapezoid is located on the side away from the first elastic member 321, and the lower base is located on the side close to the first elastic member 321. The limiting member 322 also includes an extension section fixed to the end face near the lower base of the limiting block body. The outer diameter of the extension section is smaller than the inner diameter of the mounting groove 30. The extension section can extend into the mounting groove 30. A limiting step is formed between the extension section of the limiting block body and the limiting block body. Step notches 301 are formed at both ends of the mounting groove 30. The length of the extension section is greater than the depth of the step notches 301. The extension section can extend into the step notches 301 and the mounting groove 30. The limiting step and the step notches 301 stop together to form a limit, thereby limiting the depth of the limiting member 322 extending into the mounting groove 30 and avoiding the problem that the limiting member 322 retracts too deeply and is not easy to pop out. Preferably, the stepped notch 301 has a depth of 1 mm and a width of 0.4 mm, and the bottom of the stepped notch 301 and the end face of the limiting step are both flat. The depth of the stepped notch 301 at both ends of the mounting groove 30 matches the extension stroke of the limiting member 322, ensuring that the limiting member 322 can be accurately embedded in the first limiting groove 22 or the second limiting groove 23 during the sliding process of the handle 3.

[0051] Preferably, the limiting member 322 further includes a limiting segment fixed on the side near the bottom of the limiting block body. The outer diameter of the limiting segment remains unchanged and can extend into the first limiting groove 22 or the second limiting groove 23 to improve the positioning effect.

[0052] In some specific examples, the main body of the limiting block is an isosceles trapezoid, with the two sides of the trapezoidal limiting block body at a 5° angle to the horizontal direction. This design makes it easier for the main body of the limiting block to smoothly transition and fit with the rounded corners of the limiting groove.

[0053] In some specific examples, the corners of the first limiting groove 22 and the second limiting groove 23 are rounded with a radius of R=0.3 mm to ensure that the limiting member 322 does not get stuck during the movement of the handle 3.

[0054] In some specific examples, the first elastic element 321 is a leaf spring made of 65Mn spring steel with a tensile strength ≥1800 MPa and a phosphated surface. The leaf spring has an elastic modulus of 1.2 N / mm, a length of 25 mm, a thickness of 0.8 mm, and a maximum stroke of 1.1 mm, and is used to connect and link with the limiting element 322. A through hole is opened at the lower end of the handle 3, with the limiting element 322 installed at both ends of the through hole, and the leaf spring is placed in the middle of the through hole.

[0055] In one alternative embodiment, a second elastic element 4 is provided between the handle 3 and the air regulating blade 2, the second elastic element 4 being used to apply a thrust to the handle 3 to move in the pulling direction.

[0056] In the above embodiment, the preload of the second elastic element 4 ensures that the handle 3 remains stably in the locked position. Specifically, when the handle 3 is pulled out and pushed back into the locked position after adjustment, the limiting element 322 automatically pops out and embeds into the first limiting groove 22 under the coordinated action of the second elastic element 4 and the first elastic element 321, thereby achieving stable locking of the damper opening and preventing the limiting element 322 from dislodging from the first limiting groove 22 due to the up-and-down shaking of the handle 3. This application achieves rapid compression, pop-out, and automatic fixing of the handle 3 through the linkage mechanism of the retractable limiting element 322 on both sides of the insertion end at the lower end of the handle 3 and the second elastic element 4, ensuring a stable and reliable adjustment process without the need for additional reset operations.

[0057] Optionally, the second elastic element 4 is a vertical leaf spring, which is fixed to the bottom of the insertion groove 21 of the air regulating plate 2 by riveting. The riveting point is located on the inner side of the end of the insertion groove 21, and the free end of the vertical leaf spring abuts against the lower outer surface of the handle 3. Optionally, the vertical leaf spring has an elastic coefficient of 1.5 N / mm, a length of 30 mm, a thickness of 1.0 mm, and a maximum stroke of 1.5 mm, and is used to assist the handle 3 in resetting.

[0058] In one optional embodiment, the fixed plate 1 is provided with a slide rail groove 11, and the handle 3 is provided with a sliding protrusion 33; when the handle 3 drives the air regulating plate 2 to rotate relative to the fixed plate 1 under the action of external force, the sliding protrusion 33 slides along the slide rail groove 11.

[0059] In the above embodiment, by continuously sliding the sliding convex plate 33 within the arc-shaped slide rail groove 11, the fan deflector 2 can be steplessly slid to any setting, breaking through the limitations of traditional fixed-position discrete settings. Users can adjust the damper to any opening within the allowable range of the slide rail groove 11, achieving true stepless adjustment, thus precisely adapting to diverse cooking needs such as slow simmering over low heat to high-heat braising. Furthermore, the slide rail groove 11 precisely guides and constrains the movement path of the sliding convex plate 33, ensuring the smooth rotation of the fan deflector 2 and preventing wobbling.

[0060] In this embodiment, the slide rail groove 11 is arc-shaped or fan-shaped. Preferably, the slide rail groove 11 is arc-shaped.

[0061] In one optional embodiment, the slide rail groove 11 has a first arc-shaped edge 111 and a second arc-shaped edge 112 disposed opposite to each other; wherein, the first arc-shaped edge 111 is located on the side closer to the center of the fixing piece 1, and the second arc-shaped edge 112 is located on the side farther from the center of the fixing piece 1; when the handle 3 is in the locked position, the sliding protrusion 33 is engaged and fixed to the first arc-shaped edge 111.

[0062] In the above embodiment, when the handle 3 is in the locked position, the sliding protrusion 33 is engaged and fixed to the first arc-shaped edge 111. This not only effectively fixes the air regulating plate 2 and the fixing plate 1, but also makes separation convenient without the need for external tools. Furthermore, the air regulating plate 2 adopts the design of the slide rail groove 11 described above. The first arc-shaped edge 111 and the second arc-shaped edge 112 can limit the insertion and extraction depth of the handle 3, ensuring an appropriate insertion and extraction depth and achieving precise positioning of the handle 3's up and down movement. This ensures that the elastic limiting structure 32 is firmly embedded in the first limiting groove 22 or the second limiting groove 23 and stably fixed, guaranteeing the stability and accuracy of the adjustment process.

[0063] In a further defined embodiment of the above-described embodiments, when the handle 3 is in the unlocked position, there is a set sliding gap between the sliding protrusion 33 and the second arc-shaped edge 112. In the unlocked state, the fit gap between the outer contour of the sliding protrusion 33 and the inner wall of the slide rail groove 11 is 0.15 mm, ensuring that the sliding protrusion 33 and the slide rail groove 11 slide without gap when the handle 3 moves up and down.

[0064] In other alternative embodiments, when the handle 3 is in the unlocked position, the sliding protrusion 33 abuts against the second arc-shaped edge 112, providing a stable rotation fulcrum for the adjustment process. The sliding protrusion 33 has an arc-shaped structure, with its upper and lower arc surfaces tightly fitting against the slide rail groove 11, and the handle 3 is precisely positioned by the positioning protrusion 113.

[0065] In one alternative embodiment, a plurality of positioning protrusions 113 are evenly spaced on the first arc-shaped edge 111; the sliding protrusion 33 is provided with two locking edges 331 on the side near the first arc-shaped edge 111, and the two locking edges 331 can be locked between at least two adjacent positioning protrusions 113.

[0066] In the above embodiment, the precise positioning and locking of the handle 3 can be achieved by the multiple positioning protrusions 113 evenly distributed on the first arc-shaped edge 111, and the user can be provided with staged tactile feedback of the gear position without affecting the stepless adjustment accuracy. In addition, the two locking edges 331 can be locked between any two, three, four or more adjacent positioning protrusions 113, thereby effectively fixing the handle 3, the air regulating plate 2 and the fixing plate 1.

[0067] In one specific embodiment, two snap-fit ​​edges 331 snap onto the inner edges of at least two positioning protrusions 113. The distance between the two snap-fit ​​edges 331 is set as D, and the distance between two adjacent positioning protrusions 113 is set as d. When the two snap-fit ​​edges 331 snap onto two or more positioning protrusions 113, the size of the positioning protrusions 113 needs to be considered. The width of the positioning protrusion 113 is set as D1, where D = (n-2)D1 + (n-1)d, and n is the number of positioning protrusions 113, n≥2. Preferably, the positioning protrusions 113 are cylindrical protrusion structures, and D1 is the diameter of the cylindrical positioning protrusion 113. Exemplarily, in this embodiment, the two snap-fit ​​edges 331 can snap onto any three adjacent positioning protrusions 113, that is, the distance between the two snap-fit ​​edges 331 is D = D1 + 2d.

[0068] In other alternative embodiments, the two snap-fit ​​edges 331 are engaged between the outer edges of at least two adjacent positioning protrusions 113, where D = nD1 + (n-1)d, and n is the number of positioning protrusions 113, n ≥ 2. For example, the distance between the two snap-fit ​​edges 331 is exactly equal to the distance between the outer edges of the three positioning protrusions 113. When the handle 3 is in the second limiting groove 23 position, the sliding protrusion 33 is exactly in contact with the surface of the first arc-shaped edge 111 of the slide rail groove 11, ensuring no wobbling.

[0069] This application modifies the original multiple positioning holes on the fixing plate 1 into a connected arc-shaped slide rail groove 11. The width of the slide rail groove 11 matches the radial movement stroke of the handle 3, and the length of the slide rail groove 11 matches the circumferential movement stroke of the handle 3. The bottom surface of the slide rail groove 11 is provided with several equally spaced positioning protrusions 113.

[0070] Furthermore, in this embodiment, the sliding protrusion 33 is a hollow shell structure. The circumferential edge of the sliding protrusion 33 bends and extends towards the side close to the first arc-shaped edge 111 to form two snap-fit ​​edges 331 and two connecting edges connecting the two snap-fit ​​edges 331. The two snap-fit ​​edges 331 are distributed on both sides of the sliding protrusion 33 in the sliding direction.

[0071] In one alternative embodiment, the handle 3 includes a handle body 31 and a grip portion 34. The grip portion 34 is fixedly disposed at the end of the handle body 31 away from the air regulating plate, and the grip portion 34 is provided with an anti-slip groove 341.

[0072] In the above embodiment, the grip portion 34 facilitates user operation of the handle 3, and the anti-slip groove 341 significantly increases the friction between the fingers and the handle 3, ensuring stable operation even when the user's hands are wet or oily, effectively preventing slippage and improving operational safety. This also enhances the comfort of the grip.

[0073] In a specific example, one end of the handle body 31 is inserted into the insertion slot 21 of the air regulating plate 2, and the other end is provided with a grip part 34. The grip part 34 is disc-shaped, and the anti-slip groove is a multi-ring annular groove arranged from the inside to the outside on the outer surface of the disc shape. Optionally, the groove depth is 0.15 mm, the width is 0.3 mm, and the interval is 0.3 mm.

[0074] In some embodiments, the slide rail groove 11 is formed on the outer periphery of the fixing plate 1, and a flashback plate 5 is provided on the side of the fixing plate 1 away from the slide rail groove 11. The flashback plate 5 can prevent the gas stove from flashing during use. The flashback plate 5 and the slide rail groove 11 do not overlap, ensuring that the damper adjustment mechanism and the flashback function do not interfere with each other.

[0075] The working principle and adjustment process of the damper adjustment device in this embodiment will be described below with reference to the accompanying drawings.

[0076] In actual use, the damper adjustment device provided in this embodiment achieves radial movement and positioning of the handle 3 through the cooperation of the retractable limiting member 322 with the first limiting groove 22 or the second limiting groove 23. Then, the stepless air adjustment function of the damper is realized through the slide rail groove 11 with the positioning protrusion 113 set on the fixing plate 1, which improves the inconvenience and instability of the user operation process.

[0077] In the default non-adjustable state, the handle 3 is in the retracted state, i.e., in the locked position. The two limiting members 322 (also known as telescopic buttons) at the lower end of the handle 3 are embedded in the first limiting groove 22 of the air regulating plate 2. At this time, the first elastic member 321 remains in a naturally relaxed state, while the second elastic member 4 is in a compressed state. The thrust of the second elastic member 4 and the constraint force of the two side walls of the first limiting groove 22 on the limiting member 322 work together to stably fix the handle 3 in the radial position. At the same time, the lower end face of the arc-shaped sliding protrusion 33 of the handle 3 is tightly fitted with the first arc-shaped edge 111 of the lower end face of the slide rail groove 11. Through the circumferential positioning action of multiple positioning protrusions 113 on the first arc-shaped edge 111, the handle 3 is accurately fixed in the rotation direction (circumferential direction). The axial relative position between the air regulating plate 2 and the fixed plate 1 is reliably fixed through the mechanical cooperation of other matching parts.

[0078] When preparing to adjust the damper, the user pulls the handle 3 radially. After applying sufficient force, the limiting member 322, guided by the chamfered arc, overcomes the constraint force of the first limiting groove 22 or the second limiting groove 23 and retracts, simultaneously compressing the first elastic member 321. Continuing to pull the handle 3 out, the button smoothly retracts along the second limiting groove 23, and the elastic force of the first elastic member 321 drives the limiting member 322 to pop out and precisely embed into the second limiting groove 23. At this time, the upper surface of the sliding convex plate 33 of the handle 3 fits against the second arc-shaped edge 112 of the upper end face of the slide rail groove 11, achieving precise radial positioning of the handle 3, and the damper adjustment device then enters the stepless airflow adjustment state.

[0079] During use, the user continuously adjusts the damper by pulling the handle 3 circumferentially. When the user adjusts the damper to the appropriate position, the user pushes the handle 3 radially. After applying sufficient force, the limiting member 322, guided by the arc-shaped convex groove wall, overcomes the constraint force of the convex groove wall and retracts, simultaneously compressing the first elastic member 321. Continuing to push the handle 3, the button smoothly transitions and retracts along the first limiting groove 22. The elastic force of the first elastic member 321 drives the limiting member to pop out and accurately embed into the first limiting groove 22. The lower surface of the sliding convex plate 33 of the handle 3 is tightly fitted with the lower end face of the slide rail groove 11. The left and right end faces of the arc-shaped sliding convex plate 33 cooperate with the positioning protrusions 113 on the lower end face of the slide rail groove 11 to achieve circumferential positioning. The damper adjustment is completed. At this time, the second elastic member 4 deforms under the compression of the handle 3, exerting a radial thrust on the handle 3. This causes the extended limiting member 322 to interact with the side wall of the first limiting groove 22, ensuring the handle 3 is stable within the first limiting groove 22 and achieving radial positioning.

[0080] This application innovatively adopts a separate structure of split handle 3 and air regulating vane 2, stepless adjustment slide rail groove 11 and precise linkage mechanism, which completely simplifies the damper adjustment operation process, allowing users to complete stepless damper adjustment in only three steps: "pull out - adjust - push back", without having to understand complicated steps; at the same time, through the design of customized guide rail, spring parameters and positioning protrusion 113, continuous and precise control of damper opening is achieved, effectively solving the core pain points of high operation threshold and discrete gear positions of traditional devices, and significantly improving adjustment accuracy and user experience.

[0081] According to an embodiment of the present invention, in another aspect, a gas stove is provided, including the damper adjustment device of any of the above embodiments.

[0082] This embodiment solves the problems of unintuitive operation, discrete gears, and poor adjustment accuracy of existing damper adjustment devices by using core innovations such as the split plug-in handle 3, elastic limiting structure 32, and slide rail groove 11. It greatly simplifies the user's operation process, and the damper can be continuously and steplessly controlled by pulling out, adjusting, and pushing back. The precise mechanical structure design ensures the stability and reliability of the adjustment process, and significantly improves the user experience and cooking effect of the gas stove.

[0083] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
