Abstract

As regards size reduction of a burner that draws up liquid fuel to be burned utilizing capillarity, a wick and an igniter are brought into proximity without causing contact with the flame, either a flame-producing section (61) of the wick (6) being constituted in a tapered shape at the tip portion or the tip portion of a wick holder (77) being formed to differ in height in the circumferential direction.

Independent Claims | See all claims (14)

1. 1. In a liquid fuel burner comprising a wick for drawing up by the capillarity of a draw-up section liquid fuel to be burned at a flame-producing section, an igniter for igniting the flame-producing section of the wick and a closure cap for preventing evaporation capable of sealing the flame-producing section of the wick openably and closably, a wick of the liquid fuel burner characterized in that the flame-producing section of the wick is constituted in a shape to have a tapered tip portion.
2. 8. In a liquid fuel burner comprising a wick for drawing up by the capillarity of a draw-up section liquid fuel to be burned at a flame-producing section, an igniter for igniting the flame-producing section of the wick and a closure cap for preventing evaporation capable of sealing the flame-producing section of the wick openably and closably,the liquid fuel burner characterized in that a wick holder for holding the wick is provided around the flame-producing section at a tip of the wick and a tip portion of the wick holder is formed to differ in height in a circumferential direction, a tip portion of high height being disposed to be interposed between the flame-producing section of the wick and the igniter.
