Description

Firewood saving stove Technical Field The utility model relates to the technical field of rural household cooking equipment, in particular to a firewood-saving stove. Background In rural areas, people like to cook in the outside because of higher temperature in summer, the existing cooking stoves of the oven type or biomass type are inconvenient to move outwards at any time because of larger structure, and the existing stoves have the following problems that because the air inlet is only arranged at the drawer of the ash bucket, the bottom surface and the periphery of the drawer are in contact with and sealed with the bottom surface and the periphery of the stove body, the insufficient combustion is caused by lack of enough oxygen when coal or biomass solid fuel is combusted, and a large amount of combustible gas and granular carbon black are directly discharged outwards due to insufficient combustion, so that the problem of environmental pollution exists, and the operating environment of cooking staff is bad and the human health is influenced. Disclosure of utility model The utility model provides a firewood-saving stove which is full in combustion, saves firewood and is suitable for outdoor use. The technical scheme adopted by the utility model is as follows: A firewood-saving stove comprises a stove body, wherein a stove body is arranged in the stove body, a plurality of gasification through holes are formed in the wall above the stove body, a fire grate and a dust box are sequentially arranged at the lower end of the stove body, an integral stove bottom panel is arranged at the lower end of the stove body and used for sealing the stove body, through holes with straight edges are formed in the left, right and rear three positions of the integral stove bottom panel, the through holes are communicated with a cavity between the stove body and the stove body, a baffle is arranged at the straight edges of the through holes and used for limiting the dust box, a plurality of annular grooves are pressed at the center of the integral stove bottom panel surrounded by the through holes, a plurality of annular cavities are formed between the annular grooves and the outer bottoms of the dust boxes placed on the integral stove bottom panel, and gaps are reserved between the upper ends of the dust boxes and the fire grate. The lower end wall of the furnace body is provided with a plurality of air inlets. The air inlet is round, square, pentagonal, hexagonal or rhombic. The central stove mouth of the stove top panel is provided with a ring plate with diameter gradually shrinking towards the center. The periphery of the furnace face panel is provided with downward folded edges. The periphery of the integral furnace bottom panel is provided with inverted trapezoid furnace feet.
