Description

Technical Field

[0001] This invention relates to the field of heater technology, specifically to a vertical heater that can control the heat insulation effect. Background Technology

[0002] Heaters are devices used for heating. Based on different heating media and heating principles, they can be broadly classified into: gas heating devices, electric heating devices, boiler heating devices, and electric wall-mounted boiler heating devices. They can be widely used in various civil and public buildings such as residences, offices, hotels, shopping malls, hospitals, schools, train carriages, and mobile heating, as well as simple prefabricated houses. Their characteristic is that they directly convert electrical energy or other chemical energy into heat energy and transfer heat through radiation, convection, and other means, allowing users to move around in a suitable temperature environment. In most cases, they will reduce air humidity. However, most outdoor heating devices are currently large in size, have limited heating height, and their heating range, i.e., the heat radiation range, is not adjustable or can not be changed, resulting in a single structural function. Summary of the Invention

[0003] To achieve the above objectives, the present invention is implemented through the following technical solution: a vertical heating furnace with controllable heat insulation effect, comprising an outer cylinder, wherein the bottom plate of the outer cylinder is fixedly installed with an annular stepped bottom, which is used to increase the contact area between the bottom of the outer cylinder and the ground, so that the outer cylinder is placed more stably and firmly on the ground and will not easily collapse.

[0004] A top mounting assembly, assembled on the top of the outer cylinder, is used to guide the water vapor generated during combustion. The top mounting assembly includes a top plate body, an inverted cover threadedly installed at the top center of the top plate body, and a fine filter screen fixedly connected to the bottom of the inverted cover. The inverted cover is threadedly installed to the top plate body through the fine filter screen. A top platform plate is fixedly connected to the top center of the top plate body and is correspondingly installed in the inner center of the inverted cover. An annular platform is fixedly connected between the top platform plate and the top plate body and is parallel to the top platform plate, but its top is lower than the bottom plate height of the top platform plate.

[0005] An adjustment assembly is threadedly installed on the inner side of the outer cylinder and can move up and down on the inner side of the outer cylinder. The adjustment assembly includes four support tube frames. The top of each support tube frame is fixedly connected to an upper threaded collar, and the bottom is fixedly connected to a lower threaded collar. The four support tube frames are arranged in a circular array between the upper and lower threaded collars. Each support tube frame has a slot on its side edge. The bottom of the lower threaded collar is fixedly connected to a folded connecting pipe, and the top of the lower threaded collar is connected to the inner side of the support tube frame through the lower threaded collar.

[0006] The combustion assembly is threadedly installed inside the lower threaded collar and moves up and down inside the outer cylinder via an adjusting component to heat the inside of the outer cylinder.

[0007] Preferably, a steel ring is fixedly installed at the connection between the top plate and the annular platform to prevent water droplets formed by water vapor from overflowing directly to the outer side of the top plate. Drop holes are arranged in a circular array on the inclined annular ridge of the outer side of the top plate and are located inside the steel ring to block impurities and isolate them in the gap between the steel ring and the fine filter screen, preventing impurities from flowing directly into the drop holes with the water droplets. Vent holes are arranged in a circular array on the surface of the top plate to exhaust water vapor entering the body of the top plate upwards.

[0008] Preferably, the top of the top plate is connected to a lotus leaf baffle corresponding to the air outlet. This baffle blocks the air outlet from the air, preventing foreign objects from clogging it and preventing water vapor from directly diffusing into the air. Instead, it helps water droplets condense on the lotus leaf baffle, allowing them to be guided by the annular platform and filtered by the fine filter. After entering the gap between the steel ring and the fine filter, the water droplets are reheated by the high-temperature top plate and then condensed and collected on the top plate through the inner wall of the inverted cover. They are then recovered and guided through the drop hole. This process releases some water vapor, dissipating the heat energy accumulated inside the top plate, and also guides the water vapor collected inside the top plate to the outside. During the water vapor extraction process, some of the water vapor is re-condensed, guided, filtered, re-vaporized, filtered, and re-condensed for recycling and reuse. This process avoids water vapor accumulation inside the heating furnace, which could damage the components, and also enables the recycling and reuse of water resources.

[0009] Preferably, the bottom plate of the top plate has an upper air hole in a circular array on the outer side, which is staggered with the air outlet to extend the path of water vapor in the top plate from the upper air hole to the air outlet. The heat energy carried by the water vapor itself is used to balance the heat loss when the top plate of the upper air hole comes into contact with the outside cold air in a short time. The bottom plate of the top plate has a threaded interface in the middle.

[0010] Preferably, the combustion assembly includes a fire core disc threadedly mounted inside a lower threaded collar. The top of the fire core disc has an annular groove near its outer edge, and a spiral air chamber is formed in a circular array near its center. A notch is formed on the fire core disc containing the spiral air chamber, and an annular chamfered platform is assembled on the top of the fire core disc through the notch. The outer surface of the annular chamfered platform has a circular array of spiral fire chambers that correspond to and cooperate with the spiral air chambers. The annular chamfered platform is installed in the middle of the spiral air chamber through the notch, dividing the spiral air chamber into inner and outer annular spiral guiding chambers. The outer annular spiral guiding chamber and the spiral fire chamber cooperate to guide the flame outward in an expanding spiral manner, which can increase the heating cross-sectional diameter of the flame at the initial cross-section, thereby improving the heating effect of the heating furnace by increasing the initial cross-sectional heating diameter.

[0011] Preferably, a cyclone separator is installed at the bottom of the burner core, and a combustion shell is fixedly installed at the bottom of the cyclone separator. A blower is fixedly installed on one side of the inside of the cyclone separator, with its tail end exposed at the air inlet on the surface of the cyclone separator. A heat-to-electric conversion assembly is fixedly installed on the inner bottom plate of the combustion shell, and a burner assembly is fixedly installed at the top center of the heat-to-electric conversion assembly. The burner assembly generates a flame, which heats the heat-to-electric conversion assembly to generate an electric current, thereby driving the blower to help the cyclone separator form a rotating airflow. The flame causes the hot air to flow upward due to buoyancy, attracting surrounding cold air through the cyclone separator into the combustion chamber, where it mixes with the fuel gas before combustion. When passing through a cyclone separator, certain resistance is encountered, which hinders the smooth entry of cold air. Therefore, this invention uses a blower to drive the cold air into the air inlet channel of the cyclone separator, i.e., the location where the blower is installed. With the above structure, not only is sufficient air supplied, but the tangential inflow velocity is also enhanced, and the rotation intensity is increased. Furthermore, the blower is powered by an electric current generated by the flame heating of the thermoelectric assembly, which eliminates the need for an external power source. This avoids inconvenience to the product design and avoids adding excessive structural elements that would increase the weight of the heating furnace. It reduces energy waste and increases the completeness of combustion and the effective conversion and reuse of energy.

[0012] Preferably, a heat insulation tank is threadedly installed in the middle of the bottom plate of the top plate body through a threaded interface, and four insertion pipes of equal arc length are fixedly connected to the bottom side of the heat insulation tank for insertion into the top of the support pipe rack. A glass cover is threadedly installed on the top of the fire core plate through an annular groove to cover all the flames inside the glass cover and avoid interference from external airflow to the flames. A movable door is hinged to the left side of the outer surface of the outer cylinder, and a boss is fixedly connected to the outer cylinder corresponding to the bottom of the movable door.

[0013] Preferably, a slot is provided on the inner bottom plate of the outer cylinder, so that when the adjustment component is not in use, it can be installed on the inner bottom of the outer cylinder through the bottom of the lower threaded collar in a fitting manner. This ensures that the adjustment component is stably installed inside the outer cylinder, forming an integral whole with the outer cylinder, enhancing the connection strength between the structures, preventing interference from external shaking, and possessing self-shock resistance. A heat preservation box is fixedly installed in the middle of the bottom plate inside the outer cylinder, and a drain pipe is installed through the outer surface of the boss, passing through the boss and connecting to the inside of the heat preservation box, which can drain the clean hot water collected inside the heat preservation box.

[0014] Preferably, a top-mounted spiral wall rail is fixedly installed on the top of the inner wall surface of the outer cylinder, and a bottom-mounted spiral wall rail is fixedly installed on the bottom of the inner wall surface. The top of the support tube frame is threadedly installed with the outer cylinder through an upper threaded collar and the top-mounted spiral wall rail, and the bottom of the support tube frame is threadedly installed with the outer cylinder through a lower threaded collar and the bottom-mounted spiral wall rail. Parts of the top-mounted spiral wall rail and the bottom-mounted spiral wall rail are fixedly connected to the inner wall surface of the movable door. While the wall rail at this position is normally involved in the threaded connection, it can ensure the smooth opening and closing of the movable door and will not interfere with the lifting and lowering adjustment of the adjustment component inside the outer cylinder.

[0015] Preferably, a perforated cover is installed between every two support tube frames, and the perforated cover is fitted between the two support tube frames through a fitting. Two grooves are opened on the inner wall of the outer cylinder, and a pressing plate is fitted in each groove. A cross-shaped push rod is rotatably connected to the middle of the pressing plate, and the free end of the cross-shaped push rod passes through the outer cylinder and extends to the outside of the outer cylinder. The cross-shaped push rod is threadedly connected to the outer cylinder, so that the pressing plate can be pushed out of the groove by twisting the cross-shaped push rod, and the surface of the adjusting component is pressed, which cooperates with the outer cylinder to position the adjusting component in the vertical position.

[0016] This invention provides a vertical heating stove with controllable heat insulation effect, which has the following beneficial effects:

[0017] I. This vertical heater with controllable insulation effect uses secondary condensation to return water to the inner side of the top plate. The water is then guided through the insulation tank, connecting pipe, support frame, and folded connecting pipe, and finally collected in the insulation box. When needed, the water can be directly accessed through the outlet pipe for various daily needs such as soaking feet and washing food. Furthermore, by utilizing the connection between the folded connecting pipe and the insulation box, when the hot water inside the insulation box is full, a second storage space for hot water can be temporarily provided through the insulation tank, so that users can access hot water in a timely manner. This prevents hot water from overflowing, avoids secondary waste, and avoids the risk of the flame being extinguished by hot water backflow.

[0018] II. This vertical heater, which allows for controlled insulation, uses lotus leaf-shaped baffles to shield the area directly above the vent. This prevents foreign objects from clogging the vents and avoids direct water vapor diffusion into the air. Instead, it helps water droplets condense on the lotus leaf baffles, allowing them to be guided by the annular platform and filtered through the fine filter. The water droplets then enter the gap between the steel ring and the fine filter, where they are reheated by the high-temperature top plate. After condensation on the inner wall of the inverted cover, the water is collected on the top plate and then drained through the drop holes. This process releases some water vapor, dispersing the heat accumulated inside the top plate, and simultaneously directs the collected water vapor to the outside. During this process, some of the water vapor is re-condensed, guided, filtered, re-vaporized, filtered, and then condensed again for recycling. This process prevents water vapor from accumulating inside the heater and damaging components, while also enabling the recycling of water resources.

[0019] Third, this vertical heating furnace, which can control the heat insulation effect, has an upper air hole that is arranged in a circular array on the outer side of the bottom plate of the top plate and is staggered with the air outlet. This can extend the path of water vapor in the top plate from the upper air hole to the air outlet, and use the heat energy carried by the water vapor itself to balance the heat loss when the top plate of the upper air hole comes into contact with the outside cold air in a short time.

[0020] IV. This vertical heating furnace, capable of controlling the insulation effect, allows the adjusting component to be slowly raised and lowered from the inner side of the outer cylinder by rotating it clockwise inside the outer cylinder. This continues until the upper and lower threaded collars disengage from their initial retracted positions on the top and bottom spiral wall rails. At this point, the adjusting component can slide freely up and down inside the outer cylinder. Alternatively, by twisting the cross-shaped push rod, the pressing plate can be pushed out from the groove, using the pressing plate to press against the perforated cover or support tube on the adjusting component, thus positioning the middle of the adjusting component inside the outer cylinder. Continuing to move the adjusting component upwards further... By threading the lower threaded collar and the top spiral wall rail together, the heating height of the heater is adjusted to its highest point, at which point the heater is fully exposed, providing comprehensive heating to the surrounding area. Through the above operation, the positioning height of the adjustment component inside the outer cylinder can be arbitrarily adjusted, thus allowing for arbitrary changes to the installation height of the combustion assembly inside the outer cylinder. This controls the area of ​​the combustion assembly exposed outside the outer cylinder, enabling control over the insulation effect. Therefore, it can cope with different external temperature environments and provide heating. Furthermore, by adjusting the height of the adjustment component inside the outer cylinder, the heating effect of the heater can be controlled.

[0021] V. This vertical heater, which allows for controlled insulation, achieves adjustable height of the components within the outer cylinder without using an electric mechanical lifting mechanism. This saves internal space, reduces the outer cylinder's dimensions, and lightens the overall weight of the heater. It also effectively avoids safety hazards such as damage to the electric mechanical components from high temperatures, short circuits due to moisture corrosion, or poor contact during accidental falls. Employing a simple threaded lifting and positioning system, along with compression positioning, eliminates unnecessary complex structures. This simplifies the internal structure while providing diverse functions. The water stored in the insulation tank acts as a buffer, mitigating some external impacts. Furthermore, the hot water collection process indirectly increases the heater's weight, lowering its center of gravity. This makes the heater increasingly stable on flat ground over time when used outdoors, and also provides some wind and earthquake resistance.

[0022] VI. This vertical heating furnace, which can control the heat insulation effect, has a slot on the inner bottom plate of the outer cylinder. When not in use, the adjustment component can be installed on the inner bottom of the outer cylinder through the bottom of the lower threaded collar in a fitting manner. This ensures that the adjustment component is stably installed inside the outer cylinder, forming an integral whole with the outer cylinder, enhancing the connection strength between the structures, preventing interference from external shaking, and possessing self-shock resistance.

[0023] VII. This vertical heater with controllable heat insulation effect utilizes an outer annular spiral flow chamber and a spiral fire chamber to expand the flame outward in a spiral manner. This increases the heating cross-sectional diameter of the flame at the initial cross-section, thereby improving the heating effect of the heater. Furthermore, the notch serves as the mounting interface for the annular chamfered platform on the fire core plate, facilitating assembly and disassembly, and making it easy to clean the annular chamfered platform. This prevents localized blockage of the spiral fire chamber after long-term use, ensuring that the spiral fire chamber consistently works with the spiral air chamber to guide part of the flame outward. It also heats the glass cover and perforated covers, expanding the heater's heating cross-section. This, combined with the stable upward output of the rotating flame, ensures that the entire interior covered by the glass cover, as well as the four perforated covers on the outside of the glass cover and the adjustment components, all maintain a certain temperature.

[0024] 8. This vertical heating furnace, which can control the heat insulation effect, combines a top-mounted component at the top of the flame. With some hot water recovered through the top-mounted component flowing back into the insulation tank via a support frame and a heat-insulating box, the heating device is in a heating state from top to bottom. Except for the outer cylinder, the entire furnace is in a continuous heating state, providing heat to the surroundings. This includes direct heating from the heat generated by the flame, as well as the recovery and reuse of some energy from the hot steam (i.e., the hot water vapor produced during combustion) and water resources, reducing ineffective heat loss and further improving the overall heating effect of the furnace.

[0025] 9. This vertical heating stove with controllable insulation effect generates a flame through a burner assembly. The flame heats the thermoelectric conversion assembly to generate current, which in turn drives a blower to help the cyclone separator form a rotating airflow. The flame causes the hot air to flow upward due to buoyancy, attracting surrounding cold air through the cyclone separator into the combustion chamber, where it mixes with the fuel gas before combustion. However, the air encounters resistance as it passes through the cyclone separator, hindering the smooth entry of cold air. Therefore, this invention uses a blower to drive the cold air into the air inlet channel of the cyclone separator, i.e., the location where the blower is installed. This structure not only provides sufficient air but also enhances the tangential inflow velocity and increases the rotation intensity. Furthermore, by using the current generated by the flame heating the thermoelectric conversion assembly to power the blower, the blower can achieve a stable output of rotating flame without an external power source. This avoids inconvenience to product design and does not add excessive structural elements that would increase the weight of the heating stove. It reduces energy waste and increases the completeness of combustion and the effective conversion and reuse of energy. Attached Figure Description

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0038] First embodiment, such as Figures 1 to 10 As shown, the present invention provides a technical solution: a vertical heating furnace with controllable heat insulation effect, including an outer cylinder 1, and an annular ladder bottom 8 fixedly installed on the bottom plate of the outer cylinder 1 to increase the contact area between the bottom of the outer cylinder 1 and the ground, so that the outer cylinder 1 is placed more stably and firmly on the ground and will not easily collapse.

[0039] The top mounting component 2 is assembled on the top of the outer cylinder 1 and is used to guide the water vapor generated during combustion. The top mounting component 2 includes a top plate 21. An inverted cover 22 is threadedly installed at the top center of the top plate 21, and a fine filter screen 29 is fixedly connected to the bottom of the inverted cover 22. The inverted cover 22 is threadedly installed to the top plate 21 through the fine filter screen 29. A top platform plate 23 is fixedly connected to the top center of the top plate 21 and is correspondingly installed in the inner center of the inverted cover 22. An annular platform 24 is fixedly connected between the top platform plate 23 and the top plate 21 and is parallel to the top platform plate 23, but its top is lower than the bottom plate height of the top platform plate 23.

[0040] Adjustment component 4 is threadedly installed on the inner side of outer cylinder 1 and can move up and down on the inner side of outer cylinder 1. Adjustment component 4 includes four support tube frames 41. The top of the support tube frame 41 is fixedly connected to an upper threaded collar 42 and the bottom is fixedly connected to a lower threaded collar 43. The four support tube frames 41 are arranged in a circular array between the upper threaded collar 42 and the lower threaded collar 43. Each support tube frame 41 has a slot 44 on its side edge. The bottom of the lower threaded collar 43 is fixedly connected to a folded connecting pipe 45, and the top of the lower threaded collar 43 is connected to the inner side of the support tube frame 41 through the lower threaded collar 43.

[0041] The combustion assembly 5 is threadedly installed on the inner side of the lower threaded collar 43 and moves up and down on the inner side of the outer cylinder 1 by adjusting the assembly 4, so as to heat the inner side of the outer cylinder 1.

[0042] In use, open the movable door 7, place the combustion medium inside the outer cylinder 1, connect the combustion medium to the bottom of the burner assembly 511 through the conduit, and introduce it into the burner assembly 511. Close the movable door 7, and rotate the combustion assembly 5 clockwise with the adjusting component 4. After adjusting the adjusting component 4 to the appropriate position inside the outer cylinder 1, start the burner assembly 511 to generate a flame. The flame heats the heat-to-electricity assembly 510 to generate current, which in turn drives the blower 58 to help the cyclone separator 57 form a rotating airflow. The flame causes the hot air to flow upward due to buoyancy, attracting the surrounding cold air to enter the combustion chamber through the cyclone separator 57, mix with the gas, and then burn. The air encounters a certain resistance when passing through the cyclone separator 57, thus hindering the smooth entry of cold air. This produces a stable rotating flame that burns vertically upward, continuously burning and heating inside the glass cover 6, thereby using thermal radiation to heat the surrounding area.

[0043] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 7As shown, a top-mounted spiral wall rail 9 is fixedly installed on the top of the inner wall surface of the outer cylinder 1, and a bottom-mounted spiral wall rail 10 is fixedly installed on the bottom of the inner wall surface. The top of the support tube frame 41 is threadedly installed with the outer cylinder 1 through the cooperation of the upper threaded collar 42 and the top-mounted spiral wall rail 9, and the bottom of the support tube frame 41 is threadedly installed with the outer cylinder 1 through the cooperation of the lower threaded collar 43 and the bottom-mounted spiral wall rail 10. Part of the wall rails of the top-mounted spiral wall rail 9 and the bottom-mounted spiral wall rail 10 are fixedly connected to the inner wall surface of the movable door 7. While the wall rails at this position are normally involved in the threaded connection, they can ensure the smooth opening and closing of the movable door 7, and will not interfere with the lifting and lowering adjustment of the adjustment component 4 inside the outer cylinder 1.

[0044] A steel ring 25 is fixedly installed in a ring at the connection between the top plate 23 and the annular platform 24 to prevent water droplets formed by water vapor from overflowing directly to the outer side of the top plate 23. Drop holes 26 are arranged in a circular array on the inclined annular edge of the outer side of the top plate 23 and are located inside the steel ring 25 to block impurities and isolate them in the gap between the steel ring 25 and the fine filter screen 29, preventing impurities from flowing directly into the drop holes 26 with the water droplets. Vent holes 27 are arranged in a circular array on the surface of the top plate 21 to exhaust water vapor entering the inside of the top plate 21 upwards. Lotus leaf baffles 28 are connected to the top of the top plate 21 corresponding to the vent holes 27.

[0045] The outer side of the bottom plate of the top plate 21 has an upper air hole 210 arranged in a circular array, which is staggered with the air outlet 27 to extend the path of water vapor in the top plate 21 from the upper air hole 210 to the air outlet 27. The heat energy carried by the water vapor itself is used to balance the heat loss when the top plate of the upper air hole 210 comes into contact with the outside cold air in a short time. A threaded interface 211 is provided in the middle of the bottom plate of the top plate 21.

[0046] In use, the lotus leaf baffle 28 blocks the air outlet 27 from being blocked by foreign objects, preventing water vapor from directly diffusing into the air. Instead, it helps water droplets condense on the lotus leaf baffle 28, allowing them to be guided by the annular platform 24 and filtered by the fine filter 29. After entering the gap between the steel ring 25 and the fine filter 29, the water droplets are reheated by the high-temperature top plate 21 and then condensed and collected on the top plate 23 through the inner wall of the inverted cover 22. They are then recovered and guided through the drop hole 26, releasing some water vapor and dispersing the heat energy accumulated inside the top plate 21. At the same time, the water vapor collected inside the top plate 21 is uniformly discharged to the outside. During the process of discharging water vapor, some of the water vapor is re-condensed, guided, filtered, re-vaporized and filtered, and then re-condensed for recycling and reuse. This process avoids water vapor accumulation inside the heating furnace and damage to the components, while also enabling the recycling and reuse of water resources.

[0047] The water that is condensed and returned to the inside of the top plate 21 is guided by the heat insulation tank 3, the insertion pipe 19, the support pipe rack 41, and the folded connecting pipe 45, and is finally collected in the heat preservation box 15. When needed, it can be directly taken out through the outlet pipe 17 for various daily needs such as soaking feet in hot water and washing food. Furthermore, by utilizing the connection between the folded connecting pipe 45 and the heat preservation box 15, when the heat preservation box 15 is full of hot water, the heat insulation tank 3 can temporarily provide a second storage space for the hot water, so that the user can take out the hot water in time. This prevents the hot water from overflowing and avoids secondary waste, while also avoiding the risk of the flame being extinguished by the backflow of hot water.

[0048] In use, the adjusting component 4 can be slowly raised and lowered from the inside of the outer cylinder 1 by rotating it clockwise inside the outer cylinder 1 until the upper threaded collar 42 and the lower threaded collar 43 are respectively disengaged from their respective initial storage states, corresponding to the top spiral wall rail 9 and the bottom spiral wall rail 10. At this point, the adjusting component 4 can slide freely up and down inside the outer cylinder 1. Alternatively, the pressing plate 13 can be pushed out from the inside of the groove 12 by twisting the cross rod 14. The pressing plate 13 can then press the hollow cover 11 or the support tube frame 41 on the adjusting component 4 to achieve the positioning of the middle part of the adjusting component 4 inside the outer cylinder 1. Continuing to move the adjusting component 4 upwards will further... By threading the lower threaded collar 43 to the top spiral wall rail 9, the heating height of the heater can be adjusted to the highest level, at which point the heater is fully exposed, providing comprehensive heating to the surroundings. Through the above operation, the positioning height of the adjustment component 4 inside the outer cylinder 1 can be arbitrarily adjusted, thus allowing the installation height of the combustion assembly 5 inside the outer cylinder 1 to be arbitrarily changed. This also allows control over the area of ​​the combustion assembly 5 exposed outside the outer cylinder 1, thereby controlling the heat insulation effect. As a result, it can cope with different external temperature environments and provide heating. Furthermore, by adjusting the height of the adjustment component 4 inside the outer cylinder 1, the heating effect of the heater can be controlled.

[0049] Instead of using an electric mechanical lifting mechanism to adjust the height of the adjustment component 4 inside the outer cylinder 1, this design saves internal space, reduces the processing size of the outer cylinder 1, and lightens the overall weight of the heater. It also effectively avoids safety hazards such as damage to the electric mechanical components due to high temperatures, short circuits due to moisture corrosion, or poor contact when accidentally dropped. The design employs the most basic threaded lifting and positioning, as well as compression positioning, eliminating unnecessary complex structures. This simplifies the internal structure of the heater while providing diverse functions. Furthermore, the water stored in the insulation box 15 acts as a buffer, mitigating some external impacts. During hot water collection, the weight of the heater is indirectly increased, lowering its center of gravity. This makes the heater increasingly stable when placed on flat ground outdoors over time, and also provides some wind and earthquake resistance.

[0050] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 4 to 10As shown, the combustion assembly 5 includes a burner disc 51 threadedly mounted inside a lower threaded collar 43. An annular groove 52 is formed on the top of the burner disc 51 near its outer edge. A spiral air chamber 55 is formed in a circular array near the center. A notch 56 is formed on the burner disc 51 containing the spiral air chambers 55. An annular chamfered platform 53 is assembled on the top of the burner disc 51 through the notch 56. The outer surface of the annular chamfered platform 53 has a circular array of spiral burner chambers 54 that correspond to and cooperate with the spiral air chambers 55. 3. The notch 56 is installed in the middle of the spiral air chamber 55, dividing the spiral air chamber 55 into inner and outer annular spiral drainage chambers. By utilizing the outer annular spiral drainage chamber and the spiral fire chamber 54 to expand the flame outward in a spiral manner, the heating cross-sectional diameter of the flame at the initial cross-section can be increased. This increases the heating effect of the heating furnace by increasing the initial cross-sectional heating diameter. Furthermore, the notch 56 serves as the mounting interface for the annular chamfered platform 53 on the fire core plate 51, facilitating assembly and disassembly, and making it easier to adjust the annular chamfered platform 53. Cleaning is performed to prevent local blockage of the spiral fire chamber 54 after long-term use, ensuring that the spiral fire chamber 54 can always work with the spiral air chamber 55 to guide part of the flame outward and heat the glass cover 6 and the perforated cover 11, thereby expanding the heating cross-section of the heater. This is to cooperate with the stable upward output of the rotating flame, so that the entire interior covered by the glass cover 6, as well as the four perforated covers 11 on the outside of the glass cover 6, along with the regulating component 4, all have a certain temperature. Combined with the top component 2 at the top of the flame, and the fact that some of the hot water recovered by the top component 2 flows back through the heat insulation tank 3 and the support pipe frame 41 to the heat insulation box 15, the heating device is in a heating state from top to bottom. Except for the outer cylinder 1, the entire heater is in a state of continuous heating to the surroundings. This includes the direct heating effect of the heat energy generated by the flame, as well as the recovery and reuse of some of the energy of the hot steam, i.e., the hot water steam produced during combustion, and water resources, reducing the ineffective loss of heat energy and further improving the overall heating effect of the heater.

A heat insulation tank 3 is threadedly installed in the middle of the bottom plate of the top plate 21 through a threaded interface 211. Four insertion pipes 19 are fixedly connected to the bottom side of the heat insulation tank 3 with equal arc lengths, which are used to insert into the top of the support pipe rack 41. A glass cover 6 is threadedly installed on the top of the fire core plate 51 through an annular groove 52, which is used to cover all the flames inside the glass cover 6 and avoid interference from external airflow to the flames. A movable door 7 is hinged to the left side of the outer surface of the outer cylinder 1, and a boss 16 is fixedly connected to the bottom of the movable door 7 on the corresponding outer cylinder 1.

[0052] A slot 18 is provided on the inner bottom plate of the outer cylinder 1, allowing the adjusting component 4 to be installed on the inner bottom of the outer cylinder 1 through the bottom of the lower threaded collar 43 when not in use. This ensures the stable installation of the adjusting component 4 inside the outer cylinder 1, forming an integral whole with the outer cylinder 1, enhancing the structural strength, preventing interference from external shaking, and providing self-shock resistance. An insulation box 15 is fixedly installed in the middle of the inner bottom plate of the outer cylinder 1. A drain pipe 17 is installed through the outer surface of the boss 16, passing through the boss 16 and connecting to the inside of the insulation box 15, allowing the clean hot water collected inside the insulation box 15 to be drained. Each pair of support pipes... A perforated cover 11 is installed between each of the two support tube frames 41 through a fitting 44. Two grooves 12 are opened on the inner wall of the outer cylinder 1, and a pressing plate 13 is installed in each groove 12. A cross rod 14 is rotatably connected to the middle of the pressing plate 13. The free end of the cross rod 14 passes through the outer cylinder 1 and extends to the outside of the outer cylinder 1. The cross rod 14 is threadedly connected to the outer cylinder 1. The pressing plate 13 can be pushed out of the groove 12 by twisting the cross rod 14, and the surface of the adjusting component 4 is pressed to cooperate with the outer cylinder 1 to position the adjusting component 4 in the vertical position.

[0053] In operation, a flame is generated by the burner assembly 511, which heats the thermoelectric converter 510 to generate an electric current, which in turn drives the blower 58 to help the cyclone separator 57 form a rotating airflow. The flame causes the hot air to flow upward due to buoyancy, attracting surrounding cold air through the cyclone separator 57 into the combustion chamber, where it mixes with the combustion gas before combustion. However, the air encounters resistance as it passes through the cyclone separator 57, thus hindering the smooth entry of cold air. Therefore, this invention uses the blower 58 to drive the cold air into the air inlet channel of the cyclone separator 57, i.e., the blower 58 blows air. The installation location of the machine, using the above-mentioned structure, not only provides sufficient air and enhances the tangential inflow velocity, but also increases the rotational intensity. Furthermore, by using the heat-to-electric assembly 510 heated by the flame to generate current to power the blower 58, the blower 58 can achieve a stable output of rotating flame without an external power source. This avoids inconvenience to the product design and does not add excessive structural elements that would increase the weight of the heating furnace. It reduces energy waste and increases the completeness of combustion and the effective conversion and reuse of energy.
