It utilizes a fully enclosed cylinder to enclose the flame, combined with forced air supply and staged air distribution to achieve complete combustion of waste gas at a high temperature of 800-1200℃ inside the cylinder, with a burnout rate exceeding 99%. The enclosed structure reduces combustion noise and eliminates black smoke and VOC emissions.

[0015] This invention provides a high burnout rate, low noise, smokeless, fully enclosed ground flare system. It has the following beneficial effects:

[0016] 1. This invention, through the linkage of the power supply mechanism and the liquid return mechanism, can achieve the adjustment of the air intake volume based on the amount of exhaust gas by relying on a purely mechanical structure. Therefore, there is no need for a complex control system and structure, which can reduce equipment costs and maintenance difficulty, thereby reducing the maintenance cost of the flare system.

[0017] 2. This invention, through its smoke extraction lifting mechanism, can increase the smoke extraction space when the flame is large and decrease it when the flame is small. This allows for adjustment of the smoke extraction space according to the flame size, preventing airflow from entering from the top of the flare main cylinder when the flame is small. This avoids backflow of cold air from the outside, which could cause unstable combustion, black smoke, and the risk of backfire. It can both match the rapid and smooth discharge of flue gas under high-fire conditions, reducing the pressure inside the cylinder, and reduce the smoke extraction space under low-fire conditions, maintaining a constant temperature combustion environment inside the cylinder. This further ensures the high burnout rate and low-noise, smokeless operation of the flare. Attached Figure Description

[0029] The technical solutions in 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, and 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] Please see the appendix Figure 1 - Appendix Figure 10This invention provides a high burnout rate, low noise, smokeless, fully enclosed ground flare system, including a flare main cylinder 1. A main exhaust gas pipe 2 is fixedly connected to the bottom of the main flare main cylinder 1. Multiple exhaust gas nozzles 3 are fixedly connected to the top of the main exhaust gas pipe 2. The main exhaust gas pipe 2 provides an installation position and allows exhaust gas to pass through, allowing the exhaust gas to enter the interior of the exhaust gas nozzles 3 and be ejected through the nozzles. A distribution ring 4 is fixedly connected to the outside of the main exhaust gas pipe 2. Multiple air nozzles 5 are fixedly connected to the top of the distribution ring 4, allowing air to be ejected to supplement the air required for exhaust gas combustion. A power supply mechanism 6 is located inside the main flare main cylinder 1, above the exhaust gas nozzles 3. The power supply mechanism 6, when heated, controls the amount of air entering. A liquid return mechanism 7 is located outside the power supply mechanism 6 to prevent excessive air intake due to heat accumulation. A smoke exhaust lifting mechanism 8 is provided at the top of the main torch cylinder 1. The smoke exhaust lifting mechanism 8 is used for rain protection and can also heat the air inside the main torch cylinder 1 when the flame heats the air inside the main torch cylinder 1. When the smoke exhaust lifting mechanism 8 is affected by the hot airflow, it can move upward, thereby driving the power supply mechanism 6 to move upward, so that the power supply mechanism 6 can be heated by the outer flame. An air return mechanism 9 is provided at the bottom of the outer side of the main torch cylinder 1. The air return mechanism 9 is used to discharge excess air. Multiple air inlet pipes 10 are fixedly connected to the outside of the air distribution ring 4. The bottom of the exhaust gas through the main pipe 2 is fixedly connected to the base pipe 11. The bottom of the multiple air inlet pipes 10 is fixedly connected to the outside of the base pipe 11. The exhaust gas through the outer wall of the main pipe 2 away from the base pipe 11 is fixedly connected to the exhaust gas inlet pipe 12. The base pipe 11 is not connected to the inside of the exhaust gas through the main pipe 2, but the exhaust gas inlet pipe 12 is connected to the inside of the exhaust gas through the main pipe 2.

[0031] The power supply mechanism 6 includes a liquid tank 601, which can hold electronic fluorinated liquid. This electronic fluorinated liquid has a high thermal conductivity and extremely low viscosity. When radiated by a flame, it heats up and expands synchronously within seconds, exhibiting extremely fast response. The temperature and volume expansion are approximately linear; a larger flame results in a higher temperature and a longer expansion stroke, while a smaller flame results in a lower temperature and a shorter expansion stroke. A liquid-conducting column 602 is fixedly connected to the top of the liquid tank 601, serving as a connection. An installation cylinder 603 is fixedly connected to the top of the liquid-conducting column 602, providing an installation position. A return spring 604 is installed inside the installation cylinder 603, and a piston plate 605 is slidably connected inside the installation cylinder 603. The return spring 604 provides a reaction force. When the liquid in the liquid tank 601 is heated to a small extent, it cannot push the piston plate 605 or the stroke of the piston plate 605 is small. One end of the mounting cylinder 603 is fixedly connected to the liquid temporary filling cylinder 606. When the flame stops, the piston plate 605 can be moved and reset towards the liquid temporary filling cylinder 606 under the reaction force of the return spring 604. The expanded electronic fluorinated liquid can enter the interior of the liquid temporary filling cylinder 606. The bottom of the liquid temporary filling cylinder 606 is fixedly connected to the liquid passage pipe 607, which can connect the liquid passage column 602 and the liquid temporary filling cylinder 606. The other end of the liquid passage pipe 607 is fixedly connected to the outside of the liquid passage column 602. The end of the piston plate 605 away from the liquid temporary filling cylinder 606 is fixedly connected to the movable rod 6. 08. The movable rod 608 provides an installation position. When the piston plate 605 moves, it can drive the movable rod 608 to move. A bent rod 609 is fixedly connected to the end of the movable rod 608 away from the piston plate 605. The bent rod 609 provides an installation position. An inner rod 610 is fixedly connected to the bottom of the bent rod 609. A limiting plate 611 is fixedly connected to the bottom of the inner rod 610. The limiting plate 611 has a limiting function. When the liquid tank 601 moves upward, the bent rod 609 can drive the inner rod 610 and the limiting plate 611 to move upward, thus adapting to the upward stroke of the liquid tank 601. A driving connecting rod 612 is slidably connected to the outside of the inner rod 610. The driving connecting rod 612 has a connecting function. A toothed plate 613 is fixedly connected to the bottom of the flare. When the bending rod 609 moves the inner rod 610 and the connecting rod 612, it can move the toothed plate 613. A slide bar 614 is fixedly connected to the top of the toothed plate 613. A sliding sleeve 615 is slidably connected to the outside of the slide bar 614. When the slide bar 614 slides inside the sliding sleeve 615, it can keep the toothed plate 613 stable. A mounting plate 616 is fixedly connected to the top of the sliding sleeve 615. The mounting plate 616 can install the sliding sleeve 615 and the slide bar 614. Furthermore, the toothed plate 613 can be installed using the slide bar 614. The top of the mounting plate 616 is fixedly connected to the inner wall of the flare main cylinder 1. An outer shell 617 is fixedly connected to the end of the base tube 1 away from the flare main cylinder 1.The outer casing 617 provides an installation position. A valve plate 618 is rotatably connected inside the outer casing 617. Rotation of the valve plate 618 adjusts the opening degree. A rotating shaft 619 is rotatably connected inside the outer casing 617. One end of the rotating shaft 619 is fixedly connected to a gear 620. A gear plate 613 drives the gear 620 to rotate, which in turn drives the rotating shaft 619, which in turn drives the valve plate 618 to rotate. The other end of the rotating shaft 619 is fixedly connected to the outside of the valve plate 618. The gear 620 and the gear plate 613 are meshed. Multiple stabilizing rods 621 are fixedly connected to the outside of the liquid tank 601. Multiple limiting slide rails 622 are fixedly connected to the inner wall of the flare main cylinder 1. When the stabilizing rods 621 slide inside the limiting slide rails 622, the liquid tank 601 can move upwards, while maintaining the stability of the liquid tank 601's movement. The end of the outer casing 617 furthest from the base tube 11... An air inlet pipe 623 is fixedly connected, allowing air to easily enter. The end of a stabilizing rod 621 furthest from the liquid tank 601 is slidably connected to the inside of a limiting slide rail 622. One end of a return spring 604 is fixedly connected to the inside of an mounting cylinder 603, and the other end is fixedly connected to the end of a piston plate 605 furthest from the liquid temporary inlet cylinder 606. The outside of a movable rod 608 is slidably connected to one end of the mounting cylinder 603. A limiting disc 611 is slidably connected to the top of a driving connecting rod 612. A blower 13 is installed on the outside of the flare main cylinder 1, delivering air into the air inlet pipe 623. The output end of the blower 13 is fixedly connected to the end of the air inlet pipe 623 furthest from the base pipe 11. A louvered natural air inlet 14 is fixedly connected to the bottom of the flare main cylinder 1, allowing air to enter and providing air volume for the small flame.

[0032] When the amount of exhaust gas entering is small, it enters the exhaust gas main pipe 2 through the exhaust gas inlet pipe 12 and is ejected through the exhaust gas nozzle 3. The exhaust gas can then be ignited by the continuous lamp. If sufficient air enters through the louvered natural air inlet 14, the exhaust gas nozzle 3 can burn normally, thus even a small amount of exhaust gas can be ignited. After burning for a period of time, the electronic fluorinated liquid inside the liquid tank 601 is heated. The heated electronic fluorinated liquid expands and enters the liquid-conducting column 602. However, due to the small flame, it cannot reach the liquid return mechanism 7, so the liquid return mechanism 7 does not receive enough heat and is not triggered. The liquid that expands into the liquid-conducting column 602 then returns to the liquid tank 601 through the liquid return mechanism 7. Even if the liquid tank 601 is heated by a small flame for a long time, the electronic fluorinated liquid will not enter the liquid temporary reservoir 606 due to heat accumulation. When the amount of exhaust gas increases, the flame will also become larger, thus increasing the heat generated by the flame. This will cause the electronic fluorinated liquid inside the liquid tank 601 to heat up rapidly, causing it to expand rapidly. This expansion will then enter the liquid temporary reservoir 606 through the liquid column 602, allowing the expanded electronic fluorinated liquid to enter the mounting cylinder 603. This will push the piston plate 605 away from the liquid temporary reservoir 606, compressing the return spring 604, and simultaneously causing the movable rod 608 to move away from the liquid temporary reservoir 606. The direction of movement, and due to the large flame, the liquid return mechanism 7 is also heated, which triggers the liquid return mechanism 7. The liquid inside the liquid tank 601 will not return to the inside of the liquid tank 601. When the movable rod 608 extends, it can drive the bent rod 609 and the inner rod 610 to move away from the liquid temporary cylinder 606, which in turn drives the connecting rod 612 to move, thereby driving the toothed plate 613 to move and driving the gear 620 to rotate. When the gear 620 rotates, it drives the rotating shaft 619 to rotate, which in turn drives the valve plate 618 to rotate. At the same time, the blower 13 is started, and the gas can enter the outer casing 617 through the air inlet pipe 623. Since the valve plate 618 rotates and opens, it can make The gas enters the interior of the base pipe 11 and then enters the interior of the air inlet pipe 10. Air is then ejected through the air distribution ring 4 and the air nozzle 5, thus providing sufficient air volume when there is a large amount of exhaust gas. When no more exhaust gas enters, no flame is generated. At this time, the heat of the liquid tank 601 decreases, and the electronic fluorinated liquid contracts, returning to the interior of the liquid tank 601. Under the reaction force of the return spring 604, the piston plate 605 moves towards the liquid temporary inlet cylinder 606, which in turn moves the movable rod 608 and the bent rod 609 towards the liquid temporary inlet cylinder 606. This, in turn, moves the inner rod 610, the connecting rod 612, and the toothed plate 613 in the opposite direction, and causes the gear 620 to reverse.Then, the rotating shaft 619 can drive the valve plate 618 to reverse, thereby causing the valve plate 618 to close in reverse.

[0033] The liquid reflux mechanism 7 includes a connecting pipe 701. One end of the connecting pipe 701 is fixedly connected to the outside of the liquid-passing column 602, and the other end of the connecting pipe 701 is fixedly connected to a fixing plate 702. The fixing plate 702 provides an installation position. A connecting pipe 703 is fixedly connected to the side of the fixing plate 702 away from the connecting pipe 701. The connecting pipe 701, the fixing plate 702, and the connecting pipe 703 form a reflux channel for the electronic fluorinated liquid to enter the liquid tank 601 from the liquid-passing column 602. The bottom end of the connecting pipe 703 is fixedly connected to... At the top of the liquid tank 601, a blocking plug 704 is slidably connected inside the fixing plate 702. After the blocking plug 704 moves to the bottom of the fixing plate 702, it can cut off the reflux channel of the electronic fluorinated liquid. Therefore, the downward stroke of the blocking plug 704 can control the reflux rate of the electronic fluorinated liquid. A fixing cylinder 705 is fixedly connected to the top of the fixing plate 702, providing an installation position. A connecting post 706 is fixedly connected to the top of the blocking plug 704, serving a connecting function. A sliding plate 707 is fixedly connected to the top of the 06, and the sliding plate 707 has a limiting function. A tension spring 708 is installed inside the fixed cylinder 705. The reaction force of the tension spring 708 can pull the sliding plate 707 upward, and can also drive the connecting column 706 and the blocking plug 704 to move upward. A liquid-passing curved pipe 709 is fixedly connected to the top of the fixed cylinder 705. The liquid-passing curved pipe 709 has a liquid-passing function. The other end of the liquid-passing curved pipe 709 is fixedly connected to a liquid storage tank 710. The liquid storage tank 710 contains electronic fluorine. The liquid storage tank 710 is externally fixedly connected to a mounting crank 711, which can mount the liquid storage tank 710 onto the liquid temporary filling cylinder 606. The other end of the mounting crank 711 is fixedly connected to the outside of the liquid temporary filling cylinder 606. One end of the tension spring 708 is fixedly connected to the inside of the fixed cylinder 705, and the other end of the tension spring 708 is fixedly connected to the top of the sliding plate 707. The outside of the connecting column 706 is slidably connected to the bottom of the fixed cylinder 705, and the sliding plate 707 is slidably connected to the inside of the fixed cylinder 705.

[0034] When the flame is small, it cannot reach the storage tank 710, so the electronic fluorinated liquid in the storage tank 710 will not be directly heated and expand. Therefore, under the tension of the tension spring 708, the sliding plate 707, connecting column 706, and blocking plug 704 will not move downwards. Therefore, after the inside of the liquid tank 601 is heated by a small flame for a long time, the expansion of the electronic fluorinated liquid inside the liquid tank 601 due to heat accumulation will re-enter the liquid tank 601 through the inside of the connecting pipe 701, fixing plate 702, and connecting pipe 703. When the flame is small, it cannot reach the storage tank 710, so the electronic fluorinated liquid in the storage tank 710 will not be directly heated and expand. When the flame is large, it will reach the storage tank 710, causing the electronic fluorinated liquid inside the storage tank 710 to expand due to heat. This expansion then flows through the liquid-passing conduit 709 into the fixed cylinder 705, overcoming the tension of the tension spring 708 and pushing the sliding plate 707 and connecting column 706 downwards. This, in turn, pushes the blocking plug 704 downwards. When the blocking plug 704 reaches the bottom of the fixed plate 702, the connecting pipe 701 and the connecting tube 703 are sealed, preventing the liquid entering the liquid-passing column 602 from entering the storage tank 60. The liquid inside the 1-cell housing can only allow the expanded electronic fluorinated liquid to enter the housing 603. When the flame is medium, it doesn't reach the storage tank 710, and the temperature isn't very low. Therefore, the liquid in the storage tank 710 doesn't receive much heat, resulting in minimal expansion of the electronic fluorinated liquid inside. Consequently, the liquid in the storage tank 710 doesn't exert enough force to push the sliding plate 707, and the liquid's thrust cannot completely overcome the tension of the spring 708. Therefore, the blocking plug 704 cannot completely move to its fixed position. The bottom of the fixed plate 702 is in a semi-open state, which allows some of the liquid in the liquid tank 601 to enter the interior of the liquid tank 601. As a result, the amount of liquid pushing the piston plate 605 will decrease, and thus cannot completely overcome the elastic force of the return spring 604. This shortens the stroke of the toothed plate 613, and consequently reduces the opening degree of the valve plate 618. Therefore, the amount of air entering is limited, and the amount of air entering can be automatically adjusted according to the size of the flame. Moreover, it is a completely mechanical structure, without the need for a complex control system and multiple sensors.

[0035] The smoke extraction lifting mechanism 8 includes multiple outer cylinders 801, which provide installation positions. The outer cylinders 801 are all fixedly connected to the top of the main flare cylinder 1. A limiting block 802 is slidably connected inside each outer cylinder 801, serving a limiting function. A moving rod 803 is fixedly connected to the top of the limiting block 802, serving a connecting function. Smoke extraction caps 804 are fixedly connected between the tops of the multiple moving rods 803. Smoke extraction caps 804 can move upwards when pushed by the hot airflow. Simultaneously, the moving rods 803 restrict the upward movement of the smoke extraction caps 804, preventing them from shifting. A pull rope 805 is fixedly connected to the middle of the bottom of the smoke extraction cap 804. The bottom end of the pull rope 805 is fixedly connected to the top of the mounting cylinder 603. The pull rope 805 can drive the mounting cylinder 603 and the liquid tank 601 upwards when the smoke extraction cap 804 moves upwards. When the flame is small, the amount of hot air generated by the flame is small, which is insufficient to lift the exhaust cap 804 upwards. At this time, due to the small flame, the bottom of the liquid tank 601 is in the outer flame of the small flame. When the flame is large, more hot air is generated, which can lift the exhaust cap 804 upwards under the action of the hot air. This can drive the pull rope 805 to move upwards, which in turn can drive the mounting cylinder 603 and the liquid tank 601 to move upwards. Therefore, when the flame becomes larger, the bottom of the liquid tank 601 is still in the outer flame of the larger flame. The outer flame temperature is higher, so the liquid tank 601 is always heated by the outer flame. When the liquid tank 601 moves upwards, the limit plate 611 and the inner rod 610 also move upwards, which can make the liquid tank 601 move smoothly. At the same time, the stabilizing rod 621 will also slide inside the limit slide rail 622 to maintain the stability of the upward movement of the liquid tank 601.

[0036] The air recirculation mechanism 9 includes a recirculation pipe 901, which provides an installation location and also serves as an exhaust duct. The bottom end of the recirculation pipe 901 is fixedly connected to the outside of the air inlet pipe 623. A fixing sleeve 902 is fixedly connected inside the end of the recirculation pipe 901 away from the air inlet pipe 623. A sliding hollow cylinder 903 is slidably connected inside the fixing sleeve 902. The outer wall of the sliding hollow cylinder 903 has multiple ventilation holes 904. The end of the sliding hollow cylinder 903 near the base pipe 11 is open, while the end of the sliding hollow cylinder 903 away from the base pipe 11 is open. The end is sealed. When airflow is generated, it can drive the sliding hollow cylinder 903 to move away from the base tube 11. When the vent 904 moves out of the fixed sleeve 902, it can discharge the gas. The end of the sliding hollow cylinder 903 away from the fixed sleeve 902 is fixedly connected to a sliding ring 906. The sliding ring 906 can maintain the stability of the movement of the sliding hollow cylinder 903. The inside of the return pipe 901 is fixedly connected to a limit ring 907. A pressure spring 905 is set inside the return pipe 901. The limit ring 907 plays a limiting role, so that the sliding ring 906 will not be pushed out too far by the reaction force of the pressure spring 905, thus preventing the sliding hollow cylinder 903 from moving out of the inner side of the fixed sleeve 902. One end of the pressure spring 905 is fixedly connected to the outer side of the fixed sleeve 902, and the other end of the pressure spring 905 is fixedly connected to the side of the sliding ring 906 near the fixed sleeve 902. The outer side of the sliding ring 906 is slidably connected to the inside of the return pipe 901. When the outer casing 617 is not opened, or the opening degree is not large, the air force inside the air inlet pipe 623 supplied by the blower 13 cannot fully enter the air inlet pipe 623. When the remaining air pressure is relatively large in the base pipe 11, air inlet pipe 10, air distribution ring 4 and air nozzle 5, it can overcome the elastic force of the pressure spring 905 and push the sliding ring 906 and sliding hollow cylinder 903 to move away from the base pipe 11. After the vent hole 904 on the sliding hollow cylinder 903 moves out of the inner side of the fixed sleeve 902, the remaining air volume in the air inlet pipe 623 can be discharged through the return pipe 901, sliding hollow cylinder 903 and vent hole 904, so as to avoid the air pressure inside the air inlet pipe 623 being too large and increasing the load on the blower 13.

[0037] Working principle: When the amount of waste gas entering is small, the waste gas enters the waste gas main pipe 2 through the waste gas inlet pipe 12 and is ejected through the waste gas nozzle 3. The waste gas can then be ignited by the continuous lamp. If sufficient air enters through the louvered natural air inlet 14, the waste gas nozzle 3 can burn normally, thus igniting even small amounts of waste gas. After burning for a period of time, the electronic fluorinated liquid inside the liquid tank 601 is heated. The heated electronic fluorinated liquid expands and enters the liquid-conducting column 602. However, due to the small flame, it cannot reach the liquid return mechanism 7, so the liquid return mechanism 7 does not receive enough heat and is not triggered. The liquid that expands into the liquid-conducting column 602 then returns to the liquid tank 601 through the liquid return mechanism 7. Therefore, even if the liquid tank 601 is heated by a small flame for a long time, the electronic fluorinated liquid will not enter the liquid temporary filling cylinder 606 due to heat accumulation. When the amount of exhaust gas increases, the flame will also become larger, thus increasing the heat generated by the flame. This will cause the electronic fluorinated liquid inside the liquid tank 601 to heat up rapidly, causing it to expand rapidly. This expansion will then enter the liquid temporary filling cylinder 606 through the liquid column 602, allowing the expanded electronic fluorinated liquid to enter the installation cylinder 603. This will push the piston plate 605 away from the liquid temporary filling cylinder 606 and compress the return spring 604. At the same time, it will cause the movable rod 608 to move away from the liquid temporary filling cylinder 606. The liquid reflux mechanism 7 is heated due to the large flame, causing it to be triggered. The liquid inside the liquid tank 601 will not return to its interior. When the movable rod 608 extends, it drives the bent rod 609 and inner rod 610 to move away from the liquid temporary inlet cylinder 606, which in turn drives the connecting rod 612 to move, thereby moving the toothed plate 613 and rotating the gear 620. The rotation of the gear 620 then drives the rotating shaft 619 to rotate, which in turn drives the valve plate 618 to rotate. Simultaneously, the blower 13 is activated, and gas enters the outer casing 617 through the air inlet pipe 623. The valve plate 618 rotates and opens, allowing... The gas enters the interior of the base pipe 11 and then enters the interior of the air inlet pipe 10. Air is then ejected through the air distribution ring 4 and the air nozzle 5, thus providing sufficient air volume when there is a large amount of exhaust gas. When no more exhaust gas enters, no flame is generated. At this time, the heat of the liquid tank 601 decreases, and the electronic fluorinated liquid contracts, returning to the interior of the liquid tank 601. Under the reaction force of the return spring 604, the piston plate 605 moves towards the liquid temporary inlet cylinder 606, which in turn moves the movable rod 608 and the bent rod 609 towards the liquid temporary inlet cylinder 606. This, in turn, moves the inner rod 610, the connecting rod 612, and the toothed plate 613 in the opposite direction, and causes the gear 620 to reverse.Then, the rotating shaft 619 can drive the valve plate 618 to reverse, thereby causing the valve plate 618 to reverse and close.

[0038] When the flame is small, it cannot reach the storage tank 710, so the electronic fluorinated liquid in the storage tank 710 will not be directly heated and expand. Therefore, under the tension of the tension spring 708, the sliding plate 707, connecting column 706, and blocking plug 704 will not move downwards. Therefore, after the inside of the liquid tank 601 is heated by a small flame for a long time, the expansion of the electronic fluorinated liquid inside the liquid tank 601 due to heat accumulation will re-enter the liquid tank 601 through the inside of the connecting pipe 701, fixing plate 702, and connecting pipe 703. When the flame is small, it cannot reach the storage tank 710, so the electronic fluorinated liquid in the storage tank 710 will not be directly heated and expand. When the flame is large, it will reach the storage tank 710, causing the electronic fluorinated liquid inside the storage tank 710 to expand due to heat. This expansion then flows through the liquid-passing conduit 709 into the fixed cylinder 705, overcoming the tension of the tension spring 708 and pushing the sliding plate 707 and connecting column 706 downwards. This, in turn, pushes the blocking plug 704 downwards. When the blocking plug 704 reaches the bottom of the fixed plate 702, the connecting pipe 701 and the connecting tube 703 are sealed, preventing the liquid entering the liquid-passing column 602 from entering the storage tank 60. The liquid inside the 1-cell housing can only allow the expanded electronic fluorinated liquid to enter the housing 603. When the flame is medium, it doesn't reach the storage tank 710, and the temperature isn't very low. Therefore, the liquid in the storage tank 710 doesn't receive much heat, resulting in minimal expansion of the electronic fluorinated liquid inside. Consequently, the liquid in the storage tank 710 doesn't exert enough force to push the sliding plate 707, and the liquid's thrust cannot completely overcome the tension of the spring 708. Therefore, the blocking plug 704 cannot completely move to its fixed position. The bottom of the fixed plate 702 is in a semi-open state, which allows some of the liquid in the liquid tank 601 to enter the interior of the liquid tank 601. As a result, the amount of liquid pushing the piston plate 605 will decrease, and thus cannot completely overcome the elastic force of the return spring 604. This shortens the stroke of the toothed plate 613, and consequently reduces the opening degree of the valve plate 618. Therefore, the amount of air entering is limited, and the amount of air entering can be automatically adjusted according to the size of the flame. Moreover, it is a completely mechanical structure, without the need for a complex control system and multiple sensors.

[0039] When the flame is small, the amount of hot air generated by the flame is small, which is insufficient to lift the exhaust cap 804 upwards. At this time, due to the small flame, the bottom of the liquid tank 601 is in the outer flame of the small flame. When the flame is large, more hot air is generated, which can lift the exhaust cap 804 upwards under the action of the hot air. This can drive the pull rope 805 to move upwards, which in turn can drive the mounting cylinder 603 and the liquid tank 601 to move upwards. Therefore, when the flame becomes larger, the bottom of the liquid tank 601 is still in the outer flame of the larger flame. The outer flame temperature is higher, so the liquid tank 601 is always heated by the outer flame. When the liquid tank 601 moves upwards, the limiting plate 611 and the inner rod 610 also move upwards, which can make the liquid tank 601 move smoothly. At the same time, the stabilizing rod 621 will also slide inside the limiting slide rail 622 to maintain the stability of the upward movement of the liquid tank 601.

[0040] When the outer casing 617 is not open, or is only slightly open, the airflow from the blower 13 into the air inlet pipe 623 cannot all enter the base pipe 11, air inlet pipe 10, air distribution ring 4, and air nozzle 5. When the remaining air pressure is relatively high, it can overcome the elastic force of the pressure spring 905 and push the sliding ring 906 and the sliding hollow cylinder 903 to move away from the base pipe 11. When the vent hole 904 on the sliding hollow cylinder 903 moves out of the inner side of the fixed sleeve 902, the remaining airflow in the air inlet pipe 623 can be discharged through the return pipe 901, the sliding hollow cylinder 903, and the vent hole 904, thus preventing the air pressure inside the air inlet pipe 623 from being too high and increasing the load on the blower 13.
