[0013] The beneficial effects of the present invention are: 1. The present invention adopts a cylindrical structure made of metal felt as the furnace core. The felt structure of the metal felt can better absorb oil and liquid fuel, making the furnace core easy to ignite and ensuring the combustion effect; at the same time, the furnace core made of metal material is not easy to follow the combustion loss, nor does it produce volatile substances and odors, has a long service life and is not easy to pollute the environment.

[0014] 2. The present invention is provided with a first side air vent and a second side air vent, which can improve the ventilation effect in the furnace, thereby ensuring that the oil and liquid fuel burn more fully when the furnace core is ignited. When traditional heating furnaces are filled with different fuels, it is easy to fail to ensure the fuel burns fully due to the difference in fuel quality or composition. For example, when relatively low-quality oil and liquid fuel is filled for combustion, problems such as unstable flame and black smoke often occur. When used, the present invention can ensure that the fuel burns more fully. Even if relatively low-quality oil and liquid fuel is filled, the above-mentioned black smoke problems are not likely to occur. It has a good use effect, expands the range of fuel selection, improves the flexibility of use, and reduces the cost of use.

[0015] 3. The oil storage tank of the present invention is rotatably arranged in the outer shell, and the outer shell and the oil storage tank are respectively provided with a first burner port and a second burner port of corresponding number and position. When the oil storage tank rotates, the positions of the first burner port and the second burner port will be staggered, changing the connection area of ​​the two burners, thereby realizing the adjustment of the size of the heating flame. Moreover, the first burner port and the second burner port of the present invention are arranged in a circle. When the oil storage tank rotates, multiple groups of the first burner port and the second burner port can be staggered synchronously and evenly, thereby ensuring the uniformity of the flame size adjustment.

[0016] At the same time, the first ventilation port, the second ventilation port, the first side air port and the second side air port can also adjust the connection area following the rotation of the oil storage tank, change the ventilation effect, achieve synchronous adjustment of the ventilation effect and the size of the combustion port, and synergistically improve the effect of flame size adjustment.

[0017] 4. The present invention is provided with an insulating cavity and an insulating layer. The insulating layer and the insulating cavity can greatly reduce the heat transferred from the oil storage tank to the outer shell, thereby reducing the possibility of high temperature of the outer shell, avoiding burns to people, and improving safety of use. At the same time, the present invention is also provided with a heat dissipation port connected to the insulating cavity, which accelerates the heat dissipation of the insulating cavity through the heat dissipation port, further reducing the possibility of temperature rise of the outer shell, and achieving an anti-scalding effect.

[0018] 5. The present invention is provided with a first annular rail and a second annular rail. The first annular rail and the second annular rail cooperate to limit the rotation path of the oil storage tank and improve the stability of the rotation of the oil storage tank.

[0019] The present invention also features a third circular rail, which allows the pot rack to overlap the third circular rail via slots provided therein. The third circular rail, in conjunction with the slots of the pot racks, allows the racks to be positioned and positioned simultaneously, allowing the multiple burners to be located centrally within the racks, ensuring optimal heating of the pot when placed on the racks. Furthermore, the circular rails reinforce the structure.

[0020] 6. The oil filling port of the present invention is arranged in the sink groove at the top of the shell. When filling oil, the oil fuel can be poured into the sink groove without being strictly aligned with the oil filling port. This can effectively prevent the oil fuel from overflowing due to the misalignment of the oil filling device and the oil filling port during oil filling, thereby effectively avoiding fuel waste and environmental pollution.

DETAILED DESCRIPTION

[0023] In order to make the present invention clearer and more understandable, the technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the given embodiment is only one of the implementation methods and does not represent all embodiments.

[0024] In this article, terms such as "inside, outside, up, and down" are established based on the positional relationships shown in the drawings. Depending on the different drawings, the corresponding positional relationships may also change accordingly. Therefore, they cannot be understood as absolute limitations on the scope of protection.

[0025] Combined with attachment Figure 1 -Attached Figure 10 A heating furnace for burning alcohol and oil fuel includes a furnace body, a furnace core 3 and a support frame. The support frame is arranged on the top of the furnace body and is used to place the stove to be heated. The bottom of the furnace body is provided with support legs 9, which are used to support the heating furnace and facilitate the placement of the heating furnace. At the same time, they are used to create a space between the furnace body and the work surface so that the vents at the bottom of the furnace body can be better ventilated.

[0026] The furnace body comprises a shell 1 and an oil tank 2. The oil tank 2 is rotatably mounted within the shell 1. The shell 1 is provided with an oil filling port 4 connected to the oil tank 2, through which liquid fuel is injected into the oil tank 2. The top of the shell 1 is provided with a plurality of first burners 5 spaced circumferentially. The top of the oil tank 2 is provided with second burners 6 corresponding in number and position to the first burners 5. The bottoms of the shell 1 and oil tank 2 are respectively provided with first vents 13 and second vents 14 corresponding in number and position to the first burners 5. The furnace core 3 corresponds in number and position to the second vents 14. The furnace core 3 includes a metal felt tube 33 disposed within the oil tank 2 and connected to the second vents 14. The top sides of the shell 1 and oil tank 2 are respectively provided with first side vents 7 and second side vents 8 circumferentially. The first side vents 7 correspond in number and position to the second side vents 8. During oil filling, the liquid fuel level is ensured not to exceed the height of the side vents to prevent fuel from overflowing from the side vents.

[0027] Specifically, the first combustion port 5 is fan-shaped, and the second combustion port 6 is the same size and shape as the first combustion port 5. The fan-shaped shape can ensure the uniformity of the relative position change of the two combustion ports when the first combustion port 5 and the second combustion port 6 are staggered, thereby ensuring the fire adjustment effect; the first side air port 7 is a long strip slot opened along the circumference of the outer shell 1, and the second side air port 8 is the same size and shape as the first side air port 7.

[0028] Specifically, an adjustment handle 15 is fixed to one side of the oil tank 2, an adjustment slot 1021 is provided on one side of the outer shell 1, and another adjustment slot 1021 is provided on the thermal insulation layer 18 corresponding to the position of the adjustment slot 1021. The end of the adjustment handle 15 away from the oil tank 2 passes through the two adjustment slots 1021 and extends outside the outer shell 1. The oil tank 2 is rotated by rotating the adjustment handle 15 to achieve the flame adjustment effect, which is simple and convenient to operate. The adjustment slot 1021 is provided along the circumference of the outer shell 1 and is used to limit the rotation range of the adjustment handle 15. When the adjustment handle 15 is located at one end of the adjustment slot 1021, the first burner 5 and the second burner 6 are positioned completely correspondingly and are in a fully connected state. When the adjustment handle 15 is located at the other end of the adjustment slot 1021, the second burner 6 is located between the two first burners 5, so that the two burners are in a completely disconnected state.

[0029] Specifically, the metal felt cylinder 33 is formed by randomly placing a plurality of metal wires in an interlaced manner, rolling them into a metal felt sheet, and then rolling the metal felt sheet into a cylinder to form the metal felt cylinder 33. The metal wires used in the metal felt cylinder 33 preferably have a diameter of 40-100 μm.

[0030] Specifically, the number and position of the second side tuyere 8 and the metal felt cylinder 33 correspond, that is, one side of each metal felt cylinder 33 is correspondingly provided with a second side tuyere 8. Specifically, an insulating cavity 17 is provided between the outer wall of the oil reservoir 2 and the inner wall of the outer shell 1. A thermal insulation layer is provided within the insulating cavity 17, and the insulating layer is spaced apart from the outer shell 1 and the oil reservoir 2 sidewalls. The insulating layer can be made of insulating cotton. The insulating cavity 17 and the insulating layer prevent heat transfer from the oil reservoir 2 to the outer shell 1 during heating, preventing burns and improving user safety.

[0031] More specifically, the top and bottom of the housing 1 are each provided with a heat dissipation vent 16, which communicates with an insulating cavity 17. Heat within the insulating cavity 17 can be dissipated outside the heating furnace, further preventing overheating of the furnace. More specifically, there are multiple heat dissipation vents 16, evenly spaced along the circumference of the housing 1. The number and location of the heat dissipation vents 16 located at the top of the housing 1 corresponds to the number and location of the heat dissipation vents 16 located at the bottom of the housing 1.

[0032] Specifically, a recessed groove 41 is provided at the top of the housing 1, and the fuel filling port 4 is disposed within the recessed groove 41. More specifically, the fuel filling port 4 is located at the center of the housing 1. During fueling, the fuel can be poured into either the recessed groove 41 or the fuel filling port 4, eliminating the need to strictly align the fuel filling port 4. This improves fueling convenience and prevents fuel leakage caused by misalignment between the fuel filling device (e.g., the opening of an oil storage barrel) and the fuel filling port 4.

[0033] Specifically, the furnace core 3 also includes a ventilation tube 31 and a sleeve 32. The bottom end of the ventilation tube 31 is fixedly connected to the bottom wall of the oil storage tank 2. The second ventilation opening 14 is located within the ventilation tube 31. The metal felt tube 33 is sleeved outside the ventilation tube 31, and the sleeve 32 is sleeved outside the metal felt tube 33. The top of the metal felt tube 33 is located higher than the tops of the ventilation tube 31 and sleeve 32. The bottom side of the sleeve 32 is provided with multiple through grooves 321 along the circumference. The through grooves 321 enable communication between the metal felt tube 33 and the oil storage tank 2, facilitating the metal felt tube 33 to absorb liquid fuel. Air can enter the ventilation tube 31 through the first ventilation opening 13 and the second ventilation opening 14. More specifically, the bottom end of the ventilation tube 31 is welded to the oil storage tank 2. The sleeve 32 is used to secure the metal felt tube 33 and, in conjunction with the ventilation tube 31, limits the combustible portion of the metal felt tube 33 (i.e., the length of the metal felt tube 33's top end that lies outside the ventilation tube 31 and sleeve 32). The insertion installation method of the metal felt tube 33 facilitates the disassembly and assembly of the metal felt tube 33 , thereby facilitating the replacement or maintenance of the metal felt tube 33 .

[0034] Specifically, the top of the metal felt tube 33 is flush with the top surface of the oil tank 2, preventing it from interfering with the relative rotation of the oil tank 2 and the housing 1. This ensures that the combustion flame is located at the burner port, facilitating ignition of the furnace core 3. When liquid fuel is placed in the oil tank 2, the liquid fuel level remains below the top of the sleeve 32, the top of the ventilation tube 31, and the second side tuyere 8. This prevents fuel from overflowing from the side tuyere and prevents the flame from spreading to the fuel in the oil tank 2 when the top of the furnace core 3 is ignited, thereby improving safety and stability.

[0035] Specifically, a first annular rail 1031 is provided at the bottom of the housing 1, and a second annular rail 212 is provided at the bottom of the oil tank 2. The second annular rail 212 is slidably mounted on the first annular rail 1031, and the first and second annular rails 1031 and 212 are coaxially arranged. The first and second annular rails 1031 and 212 cooperate to restrict the rotational path of the oil tank 2, thereby improving the rotational stability of the oil tank 2 and enhancing the structural integrity.

[0036] More specifically, the portion of the first annular rail 1031 located on the top side of the bottom wall of the outer shell 1 and the portion of the second annular rail 212 located on the top side of the bottom wall of the oil storage tank 2 are upward protrusions, and the portion of the first annular rail 1031 located on the bottom side of the bottom wall of the outer shell 1 and the portion of the second annular rail 212 located on the bottom side of the bottom wall of the oil storage tank 2 are upwardly recessed grooves. When the two annular rails are matched, the raised portion of the first annular rail 1031 is placed in the groove of the second annular rail 212.

The expanded structure can better gather heat and improve the heating effect. A third annular rail 1011 is provided at the top of the housing 1. The heat-collecting ring 11 is coaxially arranged with the third annular rail 1011, with the axis of the third annular rail 1011 collinear with the rotational axis of the oil tank 2. A slot is provided at the bottom of the pot support 12 to mate with the third annular rail 1011, with the outer periphery of the third annular rail 1011 positioned within the slot. When placing the support frame, the slot at the bottom of the pot support 12 rests on top of the outer periphery of the third annular rail 1011, achieving proper positioning of the support frame. Furthermore, the third annular rail 1011 enhances structural integrity.

[0038] More specifically, the sidewall of the heat-collecting ring 11 is designed with a multi-layer corrugated structure arranged from top to bottom, which can improve the structural strength of the heat-collecting ring 11. The top of the pot rack 12 is provided with raised lines, which can increase the friction when in contact with the pot and improve the placement stability of the pot.
