The invention provides a high-efficiency energy-saving environment-friendly inflamer with a multilayer ring-shaped flame structure, belonging to an inflamer used for a cookstove. The invention aims at overcoming the defect that the air and fuel gas in a combustion system are mixed and burnt at the same time in a combustion chamber, so that the fuel can be divided into a plurality of layers to be burnt to form superimposed flame. The invention adopts a premixed gas chamber and a multilayer ring-shaped flame combustion chamber; the combustion chamber is formed by overlapping and connecting multiple layers of ring-shaped clearance structure, and the ring-shaped clearance structure is a clearance (5) formed between a ring-shaped clearance sheet (3) and a ring-shaped thin slice (4), the combustion chamber is fixed inside a furnace shell (1), the premixed gas chamber (6) is formed between the combustion chamber and the inner wall of the furnace shell (1), and the premixed gas chamber is communicated with the clearance. After being fully mixed in the premixed gas chamber, the air and the fuel gas are burnt in the combustion chamber in a way of lay separation through the clearance to formthe superimposed flame, so that the combustion is more complete, and the temperature of the flame in a hearth is high, thus improving the combustion efficiency, saving energy, realizing complete combustion, reducing the emission of harmful gas and being beneficial to environmental protection.
