[0019] The carbon furnace of this utility model is described below with reference to the accompanying drawings.

[0020] Please see Figure 1 and Figure 2 , Figure 1 and Figure 2 This is a schematic diagram of the structure of a carbon furnace according to an embodiment of the present utility model; as shown Figure 1 and Figure 2 As shown, the charcoal furnace includes an upper furnace body 10 and a lower furnace body 20. The upper furnace body 10 includes an upper furnace body outer wall 11, a heat-insulating inner wall 12, and a bottom plate 13. The upper furnace body outer wall 11 is disposed above the bottom plate 13 and cooperates with the bottom plate 13 to form a cavity. The heat-insulating inner wall 12 is disposed within the cavity to divide the cavity into a heating zone and a heat-insulating zone. In this way, carbon blocks can be added to the heating zone for heating, while the heat-insulating zone effectively isolates the heat generated in the heating zone, improving the fuel utilization rate of the carbon blocks in the heating zone. At the same time, it effectively insulates against the furnace body temperature to prevent accidents caused by excessive heat. The bottom plate 13 has through holes at the position corresponding to the heating zone to form a first air inlet 14.

[0021] The lower furnace body 20 has an opening at the top, and the size of the opening is adapted to the upper furnace body to support the upper furnace body. The side wall of the lower furnace body 20 has through holes to form a second air inlet 21. In this way, the first air inlet 14, the second air inlet 21 and the opening form an effective air supply channel, which can ensure the full combustion of carbon blocks in the heating area. At the same time, by supporting the upper furnace body 10 through the lower furnace body 20, accidents caused by overheating of the bottom due to prolonged use of the carbon furnace can be avoided.

[0022] In some embodiments, the heat insulation region is filled with aluminum silicate insulation cotton or lime ash.

[0024] In some embodiments, the carbon stove further comprises a kettle rack 30, the kettle rack 30 comprises a kettle rack bottom plate 31 and a plurality of supporting legs 32, the kettle rack bottom plate 31 is arranged corresponding to the heat insulation region to close the heat insulation region by the kettle rack bottom plate 31, that is, the heat insulation region can be effectively closed by the kettle rack bottom plate 31 to avoid heat exchange between the heat insulation region and the heating region, affecting the heat insulation effect. The supporting legs 32 are used to support the object to be heated. It can be understood that the stability of the object placed can be improved by arranging a plurality of supporting legs 32 on the kettle rack bottom plate 31 to support the object to be heated.

[0025] In some embodiments, the upper stove outer wall 11, the heat insulation inner wall 12 and the bottom plate 13 are integrally formed.

[0026] It can be understood that the upper stove outer wall 11, the heat insulation inner wall 12 and the bottom plate 13 can be arranged separately, in order to facilitate cleaning of the inner cavity, the three can be arranged as clamping connection or threaded connection; for example, threaded holes corresponding to the installation stations of the heat insulation inner wall 12 and the upper stove outer wall 11 are arranged on the bottom plate 13, and the heat insulation inner wall 12 and the upper stove outer wall 11 are arranged with matching threads at the bottom to be screwed together through the threads and the threaded holes.

[0027] In some embodiments, the bottom plate 13 is provided with a protruding structure 15, and the lower stove body 20 is provided with an opening at the upper portion, the size of which is matched with the protruding structure 15, and the upper stove body 10 is clamped and connected with the lower stove body 20 through the protruding structure 15.

[0028] That is, in order to improve the stability of the connection between the upper stove body 10 and the lower stove body 20, while not affecting the manufacturing cost of the carbon stove, a protruding structure 15 is preferably arranged at the bottom of the bottom plate 13 of the upper stove body 10, so that the protruding structure 15 can effectively limit the relative displacement between the upper stove body 10 and the lower stove body 20, and improve the stability of the carbon stove during use.

[0029] In some embodiments, the carbon stove further comprises an internal fan 40, which is arranged in the lower stove body 20, and the air outlet of the internal fan 40 faces the second air inlet 21 to supply air to the second air inlet 21 through the internal fan 40.

[0030] It can be understood that by arranging the internal fan 40, the air supply efficiency can be improved, and the combustion efficiency of the fuel can be improved. Preferably, the internal fan 40 can adjust the size of the air volume to indirectly adjust the temperature of the carbon fire in the heating region.

[0034] In use, the user can align the protruding structure 15 of the upper furnace body 10 with the upper opening of the lower furnace body 20 to stably place the upper furnace body 10 on the lower furnace body 20; after the placement is completed, the kettle rack 30 is removed, and heat insulation materials are added in the heat insulation region of the upper furnace body 10; then, the kettle rack 30 is covered to close the heat insulation region; then, fuel (for example, carbon blocks) is added in the heating region of the upper furnace body 10; the fuel is ignited, and the object to be heated can be placed on the kettle rack 30 for heating. During the heating process, the air supply amount can be adjusted by the built-in fan 40 to adjust the carbon fire temperature.
