[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1-3 As shown, a greenhouse heating furnace includes a fuel tank 1 and a combustion core 2, which is disposed inside the fuel tank 1. It also includes a flame cap 3. The combustion core 2 includes a central column 21 and a wick 22. One end of the wick 22 is disposed inside the fuel tank 1, and the other end is disposed on the central column 21. The flame cap 3 covers the wick 22. The fuel tank 1 contains fuel oil. For greater environmental friendliness, fuel oil with lower sulfur and lead content can be added. The wick 22 is fixedly disposed on the central column 21, ensuring that it protrudes above the fuel oil surface. Fuel oil is continuously supplied to the protruding end of the wick 22 to ensure its combustion. This combustion provides heat and light to the crops, maintaining temperature and growth conditions at night and during rainy weather. This greenhouse heating furnace has a simple structure, reliable heating effect, and can better maintain the temperature of crops inside the greenhouse while reducing pollution to the greenhouse environment.

[0027] The top of the central column 21 is provided with several ventilation holes 211. The ventilation holes 211 provide oxygen to the flame on the wick 22, ensuring more complete combustion and avoiding the production of toxic or harmful gases such as carbon monoxide due to incomplete combustion.

[0028] The combustion core 2 also includes a connecting ring 23, which is sleeved on the central column 21. The wick 22 is disposed between the connecting ring 23 and the central column 21. The connecting ring 23 fixes the wick 22 on the central column 21, ensuring that one end of the wick 22 extends out of the oil surface and the other end is immersed in the oil surface, continuously supplying combustion fuel to the wick 22.

[0029] It also includes a fuel cap 11, which covers the fuel tank 1. The fuel cap 11 is provided with a clearance hole 12 and a fuel filling port 13. The center column 21 and the wick 22 pass through the clearance hole 12. The fuel cap 11 protects the fuel in the fuel tank 2, preventing foreign matter from entering the fuel tank 1, affecting the combustion effect, and reducing the heat preservation effect. The fuel filling port 13 is used to add fuel, and the fuel cap 131 fits onto the fuel filling port 13.

[0030] The flame cover 3 includes an inner flame shield 31, which is cylindrical and has one end positioned at the end of the central column 21 away from the fuel tank 1. The inner flame shield 31 guides the flame of the wick 22, controls the flame height, and thus controls the temperature. The flame shield 31 is mesh-like, facilitating the supply of oxygen to the flame while simultaneously releasing the heat from combustion.

[0031] The inner flame shield 31 has a pressure plate 311 and a cone 312 at the end away from the central column 21, with the cone 312 positioned between the pressure plate 311 and the central column 21. The axes of the central column 21, the cone 312, and the pressure plate 311 coincide. The pressure plate 311 prevents the flame from becoming too high and igniting crops or debris inside the greenhouse, while the cone 312, positioned between the pressure plate 311 and the central column 21, prevents the flame cup pressure plate 311 from being extinguished, thus affecting the heating effect.

[0032] The flame cover 3 also includes a flame support 32, which is arranged around the clearance hole 12. A clearance fixing ring 121 is arranged on the outer periphery of the clearance hole 12. A flame fixing ring 321 is arranged on the flame support 32. The flame fixing ring 321 and the clearance fixing ring 121 are arranged in cooperation.

[0033] The flame cover 3 also includes a flame inner cylinder 33, which surrounds the inner flame shroud 31. An inner cylinder fixing ring 322 is located at the end of the flame support 32 away from the flame fixing ring 321, and one end of the flame inner cylinder 33 is mounted on the inner cylinder fixing ring 322. The flame inner cylinder 33 protects the inner flame shroud 31, preventing the high-temperature inner flame shroud 31 from tilting, which would cause the flame to move to one side, resulting in uneven temperature distribution and a large temperature difference throughout the device.

[0034] The flame cover 3 also includes an outer flame shield 34, which surrounds the inner flame cylinder 33, and one end of the outer flame shield 34 is mounted on the flame support 32. The outer flame shield 34 has a mesh structure, which can release heat and prevent flammable materials from approaching the flame and causing a fire.

[0035] A protective net 341, which is a convex spherical surface, is provided at the end of the outer flame cover 34 away from the flame support 32. This ensures that heat can be released through the protective net 341, preventing flammable materials from approaching the flame and serving both a heat dissipation effect and an isolation function from flammable materials.

[0036] It also includes a safety cover 41, a safety ring 42, a safety net 43, a plurality of safety support columns 44 and support feet 45. The support feet 45 are fixedly mounted on the fuel cover 11. The safety ring 42 is connected to the plurality of support feet 45. One end of the plurality of safety support columns 44 is connected to the safety cover 41 and the other end is connected to the safety ring 42. The safety net 43 is arranged around the plurality of safety support columns 44.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
