Low-smoke charcoal stove

The low-smoke charcoal stove comprises an outer shell and an inner container detachably arranged in the outer shell in a matched mode, a combustion chamber is arranged in the inner container, an annular interlayer is arranged between the outer shell and the inner container, an interlayer air inlet communicated with the annular interlayer is formed in the bottom of the outer shell, and a plurality of secondary air inlet holes are formed in the upper portion of the side wall of the inner container. Oxygen enters the annular interlayer through the interlayer air inlet and then enters the upper portion of the combustion chamber through the second-stage air inlet to promote second-stage combustion in the combustion chamber. The annular interlayer is arranged to be matched with the second-stage air inlet holes and the interlayer air inlet to form a secondary air inlet channel of oxygen, secondary air can be provided for fuel which is not burnt out in the combustion chamber for secondary combustion, the fuel is full
