Detailed Description

The utility model is described in further detail below with reference to the embodiments of the drawings.

As shown in fig. 1, 2 and 3, the alcohol burner in this embodiment includes a burner base 1, a burner body 2, a burner 3 and a pan bracket 4. An air supplementing port 13 at the lateral direction of the furnace seat 1 and an upper port at the top end; the furnace body 2 is arranged in the inner cavity of the furnace seat 1. The pot support 4 is arranged on the burner 3.

The burner 3 is arranged on the upper port of the furnace seat 1 and provided with a fire hole 33 in the middle part, the middle part of the burner 3 extends downwards to form a fire guiding cylinder 31 around the fire hole 33, and an air filling gap 5 is formed between the lower end of the fire guiding cylinder 31 and the upper end of the furnace body 2. The diameter of the fire guiding drum 31 gradually decreases from bottom to top.

The upper end of the furnace seat 1 is provided with a convex ring 11, the convex ring 11 is provided with an air supplementing hole 12, and the air supplementing hole 12 is positioned above the air supplementing gap 5 and the air supplementing inlet 13.
