Secondary combustion structure of smokeless stove

Abstract

Disclosed is a secondary combustion structure of a smokeless stove. The secondary combustion structure includes: a stove body, a combustion disc and an inner wall arranged in the stove body, several separated first ventilation holes are provided in the combustion disc, a heating chamber is defined by the inner wall and the stove body, several second ventilation holes are provided in the inner wall, and an air inlet hole is further provided in the stove body. With the design, heated air flows out of the second ventilation holes to support combustion of combustible gas, further secondary combustion is achieved, a combustible is combusted more sufficiently, and smoke is reduced; and moreover, a top of the stove body is inclined towards the inner wall, so as to increase a flow speed of the heated gas, and increase a fire behavior of the combustible.

What is claimed is: 
     
         1 . A secondary combustion structure of a smokeless stove, comprising: a stove body, wherein the stove body is hollow, a combustion disc for accommodating a combustible is arranged in the stove body, several separated first ventilation holes are provided in the combustion disc, an inner wall is further vertically arranged in the stove body, the inner wall is separated from a side wall of the stove body to form a heating chamber, several separated second ventilation holes are provided in a top of the inner wall, an air inlet hole is further provided in a bottom of the stove body, and a top of the stove body is inclined towards the inner wall at a preset angle. 
     
     
         2 . The secondary combustion structure of a smokeless stove according to  claim 1 , wherein a base is further arranged at the bottom of the stove body, a protruding boss is arranged in the middle of the base, and the air inlet hole is provided in a side wall of the base. 
     
     
         3 . The secondary combustion structure of a smokeless stove according to  claim 2 , wherein the side wall of the base is inclined outwards. 
     
     
         4 . The secondary combustion structure of a smokeless stove according to  claim 2 , wherein the boss has a trapezoidal cross section.
