Description

Technical Field

[0001] The utility model relates to the technical field of wood-burning stoves, in particular to a smokeless wood-burning stove with a detachable furnace. Background Art

[0002] A wood stove is a heating device that uses wood or other combustibles to burn. It is usually used in outdoor travel, camping, outdoor barbecue and other activities. It has the advantages of being easy to use, convenient to carry, energy-saving and environmentally friendly. At present, after burning firewood, it is sometimes necessary to clean the ashes left inside the wood stove. Otherwise, the low air around the furnace and the bottom of the furnace will be blocked by slag, which will lead to a weakened combustion effect of the furnace in the later stage and an increase in the consumption of firewood.

[0003] However, the vulnerable parts of the existing wood-fired stove (especially those over 70 cm) cannot be replaced, and once the stove burns out, the entire stove is basically scrapped, which increases the cost of using the stove. To this end, we propose a smokeless wood-fired stove with a detachable stove. Utility Model Content
