Description

Technical Field

[0001] This invention belongs to the field of outdoor cooking equipment manufacturing technology, and in particular relates to a high-efficiency and energy-saving automatic fire and temperature control outdoor gas stove and its usage method. Background Technology

[0002] Outdoor gas stoves are core cooking appliances for outdoor activities such as camping and picnics. With their advantages of portability and rapid ignition, they are widely used in leisure scenarios and outdoor work fields. Their working principle is to provide fuel through a gas canister, control the gas flow through a valve body, ignite the gas through an ignition device, and form a stable fire zone at the combustion plate to heat the cookware.

[0003] The existing structure of outdoor gas stoves mainly includes core components such as a gas storage module, valve control module, ignition module, combustion plate, support frame, and windproof cover. Among these, the flame distribution of the combustion plate, the windproof effect of the windproof cover, and the gas-air mixing ratio directly affect heating efficiency and safety. However, existing outdoor gas stoves have the following key technical problems in actual use: First, wind speed fluctuates greatly in outdoor environments. Most of the wind shields on existing outdoor gas stoves are fixed ring structures, which can only block wind from one direction and cannot cope with gusts from multiple directions. When the wind exceeds the protection range of the wind shield, the flame is easily blown off course, scattered, or even goes out. Secondly, the gas supply of existing outdoor gas stoves is mostly fixed and adjustable. When the outdoor wind exceeds a certain threshold, even if the oxygen supply increases accordingly, the gas supply will remain at the original level, causing the air-fuel ratio to deviate from the ideal range. This leads to a relative excess of gas, which easily produces black smoke and carbon deposits. Incomplete combustion may even occur because the flame is stretched by strong winds. If the wind is too strong and the oxygen supply is increased but still cannot match the gas volume, the flame may be blown off course, shake violently, or even go out, seriously affecting the cooking effect and safety. At the same time, the unburned gas will be lost with the airflow, which not only causes unnecessary waste of gas resources but also does not meet the requirements of energy conservation and consumption reduction. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-efficiency, energy-saving, automatic fire and temperature control outdoor gas stove and its usage method.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows: This invention discloses a high-efficiency, energy-saving, automatic flame and temperature controlled outdoor gas stove, comprising: The base has a furnace waist ring on its top; Gas tube column, which is located inside the furnace waist ring; A gas connector, located in the middle of the furnace waist ring, is used to connect to an external gas source; The furnace lower ring is installed on the top of the base, and natural air intake holes are provided on its side wall; A gas ring nozzle is installed on the top of the gas connector; A support ring is located at the top of the furnace waist ring; Also includes: An adaptive oxygen supply component is located at the top of the furnace lower ring and is used to adjust the oxygen supply according to changes in wind force. The wind-driven assembly is located on the outside of the furnace waist ring and is linked with the adaptive oxygen supply assembly. It is driven by wind power to control the size of the oxygen supply opening. An adaptive adjustment component, located inside the base, is used to adjust the gas output according to wind force.

[0006] The adaptive oxygen supply component includes: The oxygen supply ring is a hollow ring structure located at the top of the furnace lower ring, with an oxygen supply hole on its outer side, and the gas connector is installed inside the oxygen supply ring. Several rotating rods, one end of which is laterally rotatably connected to the inside of the oxygen supply ring, and several slots are opened circumferentially on the outer side of the oxygen supply ring, with the rotating rods corresponding to the slots, and the other ends of the several rotating rods extending out of the slots. An oxygen supply plate, shaped like a petal, is located inside the oxygen supply ring, with one end fixedly connected to the rotating rod. An oxygen supply rod is installed on the rotating rod near the centrifugal end of the oxygen supply ring; An oxygen inlet hole is located at the bottom of the slot and communicates with the oxygen supply hole. An oxygen supply shield is installed at the end of the oxygen supply rod away from the rotating rod and is located inside the oxygen inlet hole. It is used to rotate with the rotating rod to open and close the oxygen inlet hole. A windproof ring, located at the top of the furnace waist ring, is a hollow ring used to block the influence of lateral wind on the flame.

[0007] Furthermore, the wind-driven assembly includes: A wind-driven ring, which is rotatably connected to the outer wall of the oxygen supply ring; Several wind-driven rods are circumferentially arranged outside the wind-driven ring, and their positions correspond one-to-one with the slots on the oxygen supply ring. Wind-driven blades are installed at the end of each wind-driven rod that extends out of the slot, and are used to receive wind force from any direction and drive the wind-driven rod to rotate around the wind-driven ring axis. A limiting plate is installed at the end of the oxygen supply rod away from the wind drive ring. A limiting groove is formed inside the limiting plate, and one end of the wind drive rod slides through the limiting groove.

[0008] Furthermore, at the bottom of the oxygen supply shield, along the direction of its rotation and closing, multiple sets of ball bearings are installed. The arrangement of the ball bearings causes the oxygen supply shield to roll along the inner wall of the oxygen inlet when it is opened, providing motion damping and guidance. When the wind weakens or disappears, the oxygen supply shield is automatically reset by the help of gravity.

[0009] Furthermore, the windproof ring includes a first annular cover and a second annular cover. The first annular cover is disposed on the top of the support ring, and the second annular cover is coaxially sleeved on the outside of the first annular cover and can slide along its axial direction. Support holes are provided at the bottom of both the first and second annular covers. At least one lifting hole is vertically provided on the inner wall of the second annular cover. A reset spring rod is installed on the bottom wall of the lifting hole. A reset block is correspondingly installed on the outer wall of the first annular cover. The reset block extends into the lifting hole and is slidably connected to the reset spring rod.

[0010] Furthermore, the top of the second annular cover is provided with an outwardly protruding oblique ring, and the top of the oblique ring is provided with a plurality of air vents along the circumference, and the air vents are arranged obliquely upward.

[0011] Furthermore, a vertical ring is installed on the inner inclined surface of the inclined ring. The vertical height of the vertical ring is lower than the height of the inclined ring. Each vertical ring has a vertically penetrating conical hole inside. The conical holes inside the vertical ring and the air outlet are arranged alternately in the circumferential direction.

[0012] Furthermore, a connecting pipe is provided below the gas ring nozzle. The top of the connecting pipe is connected to the gas ring nozzle, and the bottom is connected to the gas pipe column. Multiple first blades are circumferentially distributed on the upper outer periphery of the connecting pipe, and multiple second blades are circumferentially distributed on the lower outer periphery. Both the first blades and the second blades are curved.

[0013] Furthermore, the adaptive adjustment component includes: At least one gas branch ring is axially installed inside the gas tube column and communicates with the inner cavity of the gas tube column. An adjusting plate is rotatably disposed inside the gas branch ring to control the gas flow rate through the gas branch ring; An adjusting rod is rotatably disposed outside the tracheal column and fixedly connected to the adjusting plate to drive its rotation.

[0014] A method for using a high-efficiency, energy-saving, automatic flame-control and temperature-control outdoor gas stove includes: In the absence of wind, air enters through the natural holes of the furnace ring, the oxygen supply plate is slightly open, and oxygen is delivered to the gas ring nozzle area through the oxygen supply holes. The regulating plate is at its minimum opening to supply the basic gas volume. When there is wind, the wind force from any direction acts on the circumferentially arranged wind-driven blades, causing the wind-driven ring to rotate. The rotational motion is converted into the swing of the oxygen supply rod through the wind-driven rod and the limiting groove on the limiting plate. This causes the opening angle of the oxygen supply plate to increase synchronously and the side auxiliary oxygen inlet to open synchronously, thereby expanding the effective oxygen inlet area of ​​the main oxygen inlet channel and the auxiliary oxygen inlet channel. The greater the wind force, the greater the opening of the oxygen supply port. The opening movement of the oxygen supply plate is controlled by the adjusting plate in the rigid linkage adaptive adjusting assembly of the adjusting rod, so that the gas supply increases adaptively with the oxygen intake. When the opening of the adjusting plate increases, the gas supply increases synchronously. When the cookware is placed above the stove body, the cookware presses against the second annular cover, causing it to elastically fit against the pot wall under the action of the return spring rod, thus forming a relatively sealed combustion chamber together with the windproof ring. The airflow entering the bottom of the furnace body is decomposed into a stable, low-speed rotating airflow after passing through the first and second blades on the connecting pipe. The combustion exhaust gas is discharged in an orderly manner through the upward-sloping exhaust hole at the top of the guide ring under the action of thermal lift. When strong winds backflow, the backflowing airflow enters through the air outlet, impacts the vertical ring, and enters the staggered conical holes. After impact, deflection, and diffusion, it is weakened into diffuse airflow.

[0015] Compared with existing technologies, the high-efficiency and energy-saving automatic flame-control and temperature-control outdoor gas stove and its usage method described in this invention have the following advantages: 1. This invention utilizes the mechanical linkage of wind-driven blades, a wind-driven ring, and a limiting plate to convert wind force from any direction into a driving signal. This automatically controls the opening angle of the petal-shaped oxygen supply plate and the opening degree of the oxygen supply shielding plate, enabling the oxygen supply to adaptively increase with increasing wind force. Simultaneously, the oxygen supply plate rigidly links to the adjusting plate within the gas branch ring via an adjusting rod, ensuring synchronized adjustment of gas supply and oxygen supply. This helps maintain a consistently high-efficiency combustion range. On one hand, it overcomes the technical bottlenecks of traditional outdoor stoves in windy conditions, such as flameout, incomplete combustion, and gas waste caused by mismatch between oxygen and gas supply. It achieves intelligent firepower adjustment, resulting in a strong flame in strong winds and a stable flame in weak winds. On the other hand, it ensures that the flame remains fully developed. The blue combustion state significantly improves thermal efficiency, achieving energy saving and consumption reduction. Furthermore, this invention utilizes a retractable double-layer windproof ring structure driven by a reset spring rod, allowing the second annular cover to adaptively fit the outer wall of cookware of different sizes, forming a dynamically sealed combustion environment. Combined with the aerodynamic airflow guiding and exhaust structure formed by the top oblique ring and its obliquely upward air outlet, it not only effectively blocks lateral wind disturbance but also guides exhaust gas out and utilizes the Bernoulli effect to form an anti-turbulence thermal curtain above the cookware. Moreover, through the vertical ring and staggered conical hole distribution, it can decompose the impact force of extreme backflow airflow, achieving all-round, adaptive active wind protection, fundamentally preventing the flame from being blown off course or extinguished.

[0016] 2. This invention uses the adjusting rod of the adaptive adjustment component to rigidly link the mechanical movement of the oxygen supply plate with the gas regulating plate. When the wind force increases and the oxygen supply increases, the adjusting rod synchronously drives the regulating plate to increase the opening of the gas passage. When the wind force decreases, the system synchronously narrows the gas passage under the action of the reset mechanism. It can dynamically match the gas supply according to the actual wind conditions and combustion state, which not only prevents flame stretching and temperature drop caused by relative gas shortage under strong wind, but also avoids incomplete combustion and energy waste caused by gas excess under weak wind, so that the combustion system is always in an adaptive balance state.

[0019] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0020] See Figures 1-5As shown, this invention provides a high-efficiency, energy-saving, automatic flame and temperature controlled outdoor gas stove, comprising: a base 1 with a furnace waist ring 10 on its top; a gas pipe column 100 disposed inside the furnace waist ring 10; a gas connector 101 located in the middle of the furnace waist ring 10 for connecting to an external gas source; a furnace lower ring 102 installed on the top of the base 1, with natural air inlets on its side walls; a gas ring nozzle 11 installed on the top of the gas connector 101; a support ring 12 located on the top of the furnace waist ring 10; and an adaptive oxygen supply component 2 located on the top of the furnace lower ring 102 for adjusting the oxygen supply according to wind changes. The adaptive oxygen supply component 2 includes an oxygen supply ring 21, which is a hollow ring structure located on the top of the furnace lower ring 102, with oxygen supply holes 22 on its outer side. The gas connector 101 is installed on the oxygen supply ring. Inside the oxygen supply ring 21: Several rotating rods 23 are connected to the inside of the oxygen supply ring 21 at one end, and several slots are opened on the outer circumference of the oxygen supply ring 21, with the rotating rods 23 corresponding to the slots. The other ends of the rotating rods 23 extend into the slots. An oxygen supply plate 24, in the shape of a petal, is located inside the oxygen supply ring 21, with one end fixedly connected to the rotating rod 23. An oxygen supply rod 25 is installed on the rotating rod 23 near the centrifugal end of the oxygen supply ring 21. An oxygen inlet hole 26 is opened at the bottom of the slot and communicates with the oxygen supply hole 22. An oxygen supply shielding plate 27 is installed on the end of the oxygen supply rod 25 away from the rotating rod 23 and is located inside the oxygen inlet hole 26. It is used to open and close the oxygen inlet hole 26 as the rotating rod 23 rotates. A windproof ring 28 is located at the top of the furnace waist ring 10 and is in the shape of a hollow ring. It is used to block the influence of lateral wind on the flame.

[0021] It should be noted that in the absence of wind or in the presence of a slight breeze, air mainly enters through the natural air intake holes of the furnace lower ring 102, and enters the interior of the oxygen supply ring 21 through the slightly open gap of the oxygen supply plate 24. Oxygen is transported upward through the oxygen supply hole 22 to the area around the gas ring nozzle 11, where it mixes with the gas and is fully combusted. At this time, the wind force is insufficient to drive the wind drive assembly 211, and the oxygen supply system maintains a basic oxygen supply state. In windy conditions, the wind force acts on the wind drive assembly 211, driving the rotating rod 23 linked to it to rotate. The rotating rod 23 causes the oxygen supply plate 24 to gradually open, increasing the oxygen intake channel. At the same time, the oxygen supply rod 25 drives the oxygen supply shield 27 to rotate out of the oxygen intake hole 26, increasing the opening of the oxygen supply hole 22. Specifically, the stronger the wind, the larger the opening angle of the oxygen supply plate 24, and the more oxygen is supplied, ensuring that the gas can still obtain sufficient oxygen under strong winds, avoiding incomplete combustion or flameout due to lack of oxygen. The windproof ring 28 surrounds the gas ring nozzle 11. When the cookware is placed on it, a relatively closed combustion space can be formed, effectively blocking the direct impact of lateral and rotating winds on the flame.

[0022] This invention utilizes a windproof ring 28, an adaptive oxygen supply component 2, and a natural hole design in the furnace bottom ring 102. The main function of the windproof ring 28 is to weaken and disrupt the direct path of lateral winds, making it difficult for them to directly impact the flame root. When the wind force increases, the wind-driven component 211 is activated, and the opening angle of the oxygen supply plate 24 increases. This means that when the wind force is strong, the windproof system actively draws in more air from below, forming a stable, upward airflow column. This airflow column has two key functions: first, the upward airflow creates a slight positive pressure in the furnace head area, effectively resisting the intrusion of external turbulent airflow; second, it precisely delivers oxygen to the mixing zone of the gas ring nozzle 11, ensuring that the gas and fresh air are fully premixed, resulting in more intense combustion, a stronger flame, and naturally enhanced wind resistance. This allows the gas ring nozzle 11 to receive more oxygen and a more stable flame as the wind blows, rather than becoming increasingly oxygen-deficient.

[0023] Moreover, this invention requires wind power to be used as the driving energy and adjustment signal in the adaptive oxygen supply component 2. Specifically, in the absence of wind or in a light breeze, the oxygen supply plate 24 is slightly open, and the system relies on natural convection for oxygen supply, which is in an energy-saving state. In the presence of wind, the wind drives the wind drive component 211, which in turn drives the rotating rod 23 to rotate, increasing the angle of the oxygen supply plate 24 and the air intake area. At the same time, the oxygen supply shield 27 rotates out, and the opening of the oxygen inlet hole 26 becomes larger. The stronger the wind, the larger these openings become, actively capturing more wind as oxygen for combustion. External gusts will not extinguish the flame but will instead be utilized by the system to enhance combustion, fundamentally mitigating the risk of flameout.

[0024] See Figures 4-6 As shown, the wind-driven assembly 211 is located on the outside of the furnace waist ring 10 and is linked with the adaptive oxygen supply assembly 2. It is driven by wind power to control the size of the oxygen supply opening. The wind-driven assembly 211 includes a wind-driven ring 212, which is rotatably connected to the outer wall of the oxygen supply ring 21; several wind-driven rods 213 are circumferentially arranged outside the wind-driven ring 212, and their positions correspond one-to-one with the slots on the oxygen supply ring 21; wind-driven blades 215 are installed at the end of each wind-driven rod 213 that extends out of the slot, and are used to receive wind power from any direction and drive the wind-driven rods 213 to rotate around the axis of the wind-driven ring 212; a limiting plate 214 is installed at the end of the oxygen supply rod 25 away from the wind-driven ring 212. The limiting plate 214 has a limiting groove inside, and one end of the wind-driven rod 213 slides through the limiting groove, thereby converting the rotational motion of the wind-driven ring 212 into the swing of the oxygen supply rod 25, which in turn drives the oxygen supply shielding plate 27 to open and close the oxygen inlet hole 26.

[0025] It should be noted that the wind-driven blades 215 are driven by wind power, which drives the wind-driven ring 212 and the wind-driven rod 213 to rotate; the wind-driven rod 213 drives the oxygen supply rod 25 to swing through the limiting groove on the limiting plate 214, thereby synchronously controlling the opening angle of the oxygen supply plate 24 and the position of the oxygen supply shield 27, so as to realize the adaptive adjustment of the oxygen supply.

[0026] It is worth noting that the multiple circumferentially distributed wind-driven blades 215 constitute an omnidirectional wind cup sensor. No matter which angle the wind blows from in the horizontal direction, it will always act on at least one blade, generating rotational torque and driving the wind-driven ring 212 to rotate. This solves the problem that traditional fixed baffles are only effective for wind in a specific direction, enabling the stove to cope with turbulence, vortex winds, and irregular gusts, achieving true all-round environmental adaptability. At the same time, the wind-driven assembly 211 converts the rotational motion into the precise swing of the oxygen supply rod 25 through the sliding design of the limiting plate 214 and the limiting groove, thereby synchronously controlling the oxygen supply plate 24 and the oxygen supply baffle 27. The whole process does not require electronic sensors, controllers, or external energy, and is completely driven by wind power, achieving high reliability, long life and zero energy consumption self-adjustment.

[0027] See Figure 6 As shown, multiple sets of ball bearings 271 are installed at the bottom of the oxygen supply shield 27 along the direction of its rotation and closing. The ball bearings 271 are arranged so that the oxygen supply shield 27 rolls along the inner wall of the oxygen inlet hole 26 when it is opened, providing motion damping and guidance. When the wind weakens or disappears, the oxygen supply shield 27 is automatically reset by the help of gravity.

[0028] It should be noted that under the impact of a sudden strong gust of wind, the wind-driven blade 215 may instantly obtain a large torque. Without buffering, the oxygen supply baffle 27 will suddenly open completely, causing a drastic step change in the amount of oxygen and fuel. The flame may fluctuate violently or even flicker. Therefore, rolling friction is formed between the ball bearing 271 and the inner wall of the oxygen inlet 26. Compared with sliding friction, rolling friction itself is smaller and allows for smooth movement. However, its inherent inertia and contact with the hole wall establish a mechanical damper. When a strong wind suddenly strikes, the rapid increase in driving force needs to overcome the inertia of the ball bearing 271 and make it roll faster. This process absorbs some of the impact energy, making the opening action of the oxygen supply baffle 27 smooth and linear, rather than suddenly popping open. This ensures a smooth transition of oxygen supply changes, allowing the flame to strengthen steadily and improving the dynamic stability against wind disturbance. Moreover, when the wind weakens and the driving torque is less than the reset torque, the baffle plate tends to close downward and inward under the weight of the oxygen supply plate 24. Since the ball bearing 271 is installed on the side of the rotation closing direction, when the baffle plate begins to fall back, the contact point between the ball bearing 271 and the hole wall provides a downward gravitational component force. This component force acts like a booster, helping to overcome possible jamming and ensuring that the baffle plate can reliably and completely reset to the initial slightly open position. It can effectively help overcome the movement jamming caused by oil stains, dust accumulation or slight deformation in the outdoor environment.

[0029] See Figures 7-8As shown, the windproof ring 28 includes a first annular cover 281 and a second annular cover 282. The first annular cover 281 is disposed on the top of the support ring 12. The second annular cover 282 is coaxially sleeved on the outside of the first annular cover 281 and can slide along its axial direction. Support holes are provided at the bottom of both the first annular cover 281 and the second annular cover 282. At least one lifting hole 283 is vertically provided on the inner wall of the second annular cover 282. A reset spring rod 284 is installed on the bottom wall of the lifting hole 283. A reset block 285 is correspondingly installed on the outer wall of the first annular cover 281. The reset block 285 extends into the lifting hole 283 and is slidably connected to the reset spring rod 284.

[0030] It should be noted that the first annular cover 281 and the second annular cover 282 are connected together or separately to the support ring 12 on the top of the stove through the support holes at their bottoms. At this time, the return spring rod 284 is in a naturally extended state, providing upward support for the second annular cover 282. When the user places the pot on the support ring 12, the outer wall of the pot will contact the upper edge of the higher second annular cover 282. As the pot continues to be lowered until it is stable, its lateral pressure will act on the second annular cover 282. Under pressure, the second annular cover 282 overcomes the elasticity of the return spring rod 284 and slides down along the outer wall of the first annular cover 281. The return block 285 slides down along the return spring rod 284 in the lifting hole 283. The spring is compressed and stores elastic potential energy. This process continues until the pot is completely stable. At this time, the upper edge of the second annular cover 282 is tightly and flexibly attached to the outer wall of the pot under the spring pressure. No matter if the pot vibrates slightly due to boiling or stirring, or is impacted by lateral gusts of wind, the elasticity of the return spring rod 284 can keep the second annular cover 282 always attached to the pot wall, continuously blocking the path of lateral wind from entering through the gaps.

[0031] The problem of gaps between the traditional fixed windproof ring 28 and cookware of different sizes and shapes has been solved. Through the floating structure driven by the reset spring rod 284, the second annular cover 282 can automatically press down or rebound, so that its upper edge always maintains elastic and tight contact with the pot wall. Moreover, it prevents the rigid impact on the stove structure caused by improper operation or excessive weight of the pot when the user places the pot, thus protecting the windproof ring 28 and the stove body.

[0032] In addition, after the windproof ring 28 is tightly attached to the pot wall, it together with the pot body forms a closed combustion chamber that is narrow at the top and wide at the bottom. The adaptive oxygen supply component 2 increases the air intake under the drive of wind, which accelerates the rise of the hot air in the furnace and generates a strong, stable suction airflow from bottom to top. This can effectively counteract and disrupt the gusts of wind that invade from the side, prevent them from blowing the flame base off to the side, and fundamentally improve the wind resistance.

[0033] See Figure 8As shown, the top of the second annular cover 282 is provided with an outwardly protruding oblique ring 286, and the top of the oblique ring 286 is provided with a plurality of air vents 287 along the circumferential direction, and the air vents 287 are arranged obliquely upward.

[0034] It should be noted that the high-temperature exhaust gas generated after the gas is fully burned in the burner naturally rises to the bottom of the pot under the action of thermal lift and accumulates at the top of the combustion chamber formed by the pot body and the windproof ring 28. Under pressure, the high-temperature exhaust gas is guided by the inclined ring 286 structure and concentrated and evenly sprayed out slightly upward and outward from these air outlets 287, forming a high-temperature air curtain around the pot body, so that the exhaust gas can be discharged in time. By designing the inclined upward arrangement, the natural buoyancy of the hot exhaust gas is maximized, making its discharge smoother and more thorough.

[0035] The convex inclined structure of the inclined ring 286 can effectively deflect and guide the destructive airflow from above, greatly reducing the probability of strong winds directly impacting the flame. Moreover, the upward-sloping air outlet 287, in conjunction with the Bernoulli effect, transforms a simple exhaust port into a directional micro-jet. The upward-sloping hot air curtain it discharges forms a protective layer of hot air with upward kinetic energy above the pot. This protective layer can effectively lift, disrupt, and counteract some of the downward-pressing airflow over the pot, further improving wind resistance.

[0036] See Figure 8 As shown, a vertical ring 288 is installed on the inner inclined surface of the inclined ring 286. The vertical height of the vertical ring 288 is lower than the height of the inclined ring 286. Each vertical ring 288 has a tapered hole 289 that runs vertically through it.

[0037] It should be noted that when an extremely strong wind, such as a sudden gale, generates a super-strong airflow that overcomes the aerodynamic defenses of the oblique ring 286 and flows back into the interior of the oblique ring 286 from the air outlet 287, it will first collide head-on with the vertical ring 288. Part of this destructive straight-line impact airflow is forced to make a sharp turn and flow upward, while the other part is forced to enter the conical hole 289. In this violent change of direction, a large amount of the airflow's kinetic energy is rapidly consumed due to friction with the ring wall of the vertical ring 288 and the impact within the conical hole 289. The flow velocity and impact force are further significantly weakened, causing the flow velocity to drop sharply again and become more uniform and stable, without affecting the exhaust gas discharge. Through passive energy dissipation, it ensures that the flame will not be blown out from above under any foreseeable conditions, providing absolute safety and eliminating the risk of extreme flameout.

[0038] The conical holes 289 and the air vents 287 inside the vertical ring 288 are arranged alternately in the circumferential direction.

[0039] It should be noted that, since the vertical ring 288 and the conical hole 289 are arranged alternately with the air outlet 287, the multiple streams of air flowing back from different air outlets 287 will collide, interfere and mix with each other in the conical cavity, further disintegrating their unified impact direction and energy.

[0040] See Figures 9-11 As shown, a connecting pipe 221 is provided below the gas ring nozzle 11. The top of the connecting pipe 221 is connected to the gas ring nozzle 11, and the bottom is connected to the gas pipe column 100. Multiple first blade plates 222 are installed in a circumferential distribution on the upper outer periphery of the connecting pipe 221, and multiple second blade plates 223 are installed in a circumferential distribution on the lower outer periphery. Both the first blade plates 222 and the second blade plates 223 are curved.

[0041] It should be noted that, in order to prevent air rushing in from below the furnace body, especially in strong winds, from directly impacting the gas ring nozzle 11 in a turbulent and high-speed manner, this invention first encounters the second blade plate 223 with the rising airflow. Its curved surface forces the airflow to change direction, for example, from vertical upward to rotation. This process consumes part of the airflow's kinetic energy and reduces its direct velocity. Subsequently, the airflow continues to rise and encounters the first blade plate 222, whose curved design causes the airflow direction to change again. After these two organized changes in direction, the high-speed straight airflow that might have caused an impact is decomposed and dispersed into a uniform flow, providing an extremely stable gas field for the flame and ensuring exceptional stability at the flame root. This is the physical basis for achieving flameout prevention and consistent firepower even in strong winds.

[0042] At the same time, under a sudden strong wind, the cold air directly participating in combustion will reduce the flame temperature and affect thermal efficiency. By utilizing the radiant heat of the combustion zone and the conductive heat of the wall of the connecting pipe 221, which is located below the flame, the first blade plate 222 and the second blade plate 223 are heated. When the air flows through the surface of the first and second blade plates 223, sufficient heat exchange occurs, and the air temperature is significantly increased, thus achieving the purpose of energy saving.

[0043] See Figures 9-12 As shown, the adaptive adjustment component 3 is located inside the base 1 and is used to adjust the gas output according to the wind force. The adaptive adjustment component 3 includes at least one gas branch ring 31, which is axially installed inside the gas column 100 and communicates with the inner cavity of the gas column 100; an adjustment plate 32, which is rotatably located inside the gas branch ring 31 and is used to control the gas flow rate through the gas branch ring 31; and an adjustment rod 33, which is rotatably located outside the gas column 100 and is fixedly connected to the adjustment plate 32 to drive its rotation.

[0044] It should be noted that when there is no wind, the oxygen supply plate 24 is slightly open, and the corresponding regulating plate 32 is at its minimum opening, providing the basic gas volume to maintain stable combustion of the small flame, achieving high efficiency and energy saving. When the wind is strong, the wind drives the oxygen supply plate 24 to open, and the regulating rod 33 immediately drives the regulating plate 32 to rotate and increase the opening in the same direction. While the oxygen intake increases, the gas supply also increases simultaneously. This ensures that the mixing ratio of oxygen and gas is always automatically maintained within a narrow range close to the theoretical air-fuel ratio throughout the entire range of wind changes. This design fundamentally eliminates this problem through rigid mechanical proportional linkage, ensuring that the flame is always a fully combusted blue flame with the highest thermal efficiency. Moreover, the output firepower of the stove is no longer a fixed value manually set by the user, but is intelligently adjusted according to the wind environment. It automatically switches to high firepower when the wind is strong and automatically switches to energy-saving small flame when the wind is weak. The whole process does not require user intervention, and the combustion state is always optimal.

[0045] The method of using a high-efficiency, energy-saving, automatic flame-control and temperature-control outdoor gas stove includes the following steps: First, when there is no wind, air enters through the natural hole of the furnace ring 102, the oxygen supply plate 24 is slightly open, and oxygen is delivered to the area of ​​the gas ring nozzle 11 through the oxygen supply hole 22. The regulating plate 32 is at the minimum opening to supply the basic gas quantity. Second, when there is wind, when the wind blows from any direction, the circumferentially arranged wind-driven blades 215 capture wind energy and drive the wind-driven ring 212 to rotate. The wind-driven rod 213 converts the rotational motion into the swing of the oxygen supply rod 25 through the limiting groove on the limiting plate 214. Third, the swing of the oxygen supply rod 25 drives the rotating rod 23, which increases the opening angle of the petal-shaped oxygen supply plate 24, expands the main oxygen supply channel, and drives the oxygen supply shield 27 to rotate out of the oxygen inlet hole 26. The side auxiliary oxygen inlet hole 26 opens simultaneously. The greater the wind force, the greater the opening of the oxygen supply port. Fourth, the movement of the oxygen supply plate 24 is achieved through the rigid linkage adaptive adjustment assembly 3 with the adjustment rod 33, and the opening of the adjustment plate 32 increases accordingly, and the gas supply increases synchronously, which helps to maintain the high-efficiency combustion range. Fifth, when placing the pot, the pot body presses against the second annular cover 282, causing it to slide down against the elastic force of the return spring rod 284. Under the action of the spring force, its top tightly and elastically fits against the pot wall. The windproof ring 28 and the pot body together form a relatively sealed combustion chamber. Sixth, the airflow entering from the bottom is decomposed into a stable, low-speed rotating airflow after being guided twice by the first blade plate 222 and the second blade plate 223 on the connecting pipe 221. Under the action of thermal lift, the combustion exhaust gas is guided to the upward-sloping exhaust hole 287 at the top of the inclined ring 286 and discharged in an orderly manner. This design utilizes the Bernoulli effect, which can not only exhaust smoothly, but also actively guide away and resist the top airflow. Seventh, in the event of extreme strong wind backflow, the airflow enters through the air outlet 287, impacts the vertical ring 288, and enters the staggered conical holes 289. Through impact, turning, diffusion, and mutual interference, the strong impact airflow is weakened into harmless diffuse airflow.

A method for using a high-efficiency, energy-saving, automatic flame-control and temperature-control outdoor gas stove, characterized in that: The high-efficiency energy-saving automatic flame-control and temperature-control outdoor gas stove as described in any one of claims 1-9 includes: In the absence of wind, air enters through the natural holes of the furnace ring (102), the oxygen supply plate (24) is slightly open, and oxygen is transported through the oxygen supply hole (22) to the gas ring nozzle (11) area. The regulating plate (32) is at its minimum opening to supply the basic gas volume. When there is wind, the wind force from any direction acts on the circumferentially arranged wind-driven blades (215), causing the wind-driven ring (212) to rotate. Through the wind-driven rod (213) and the limiting groove on the limiting plate (214), the rotational motion is converted into the swing of the oxygen supply rod (25), which causes the opening angle of the oxygen supply plate (24) to increase synchronously and the lateral auxiliary oxygen inlet hole (26) to open synchronously, thereby expanding the effective oxygen inlet area of ​​the main oxygen inlet channel and the auxiliary oxygen inlet channel. The greater the wind force, the greater the opening of the oxygen supply port.

When the opening of the regulating plate (32) increases, the gas supply increases synchronously. When the pot is placed above the stove body, the pot body presses against the second annular cover (282), so that it forms an elastic fit with the pot wall under the action of the return spring rod (284), thus forming a relatively sealed combustion chamber together with the windproof ring (28); The airflow entering the bottom of the furnace body passes through the first blade plate (222) and the second blade plate (223) on the connecting pipe (221) twice and is decomposed into a stable, low-speed rotating airflow. The combustion exhaust gas is discharged in an orderly manner through the upward air outlet (287) at the top of the guide inclined ring (286) under the action of thermal lift. When strong backflow occurs, the backflowing airflow enters through the air outlet (287), impacts the vertical ring (288), and enters the staggered conical holes (289). After impact, deflection, and diffusion, it is weakened into diffuse airflow.
