The invention relates to a combustion device for combusting a liquid fuel, comprising a fuel reservoir, a combustion chamber, at least one wick holder for holding a wick, an extinguisher cooperating with the or each wick holder, the extinguisher being displaceable between a flame supporting position and a flame extinguishing position; a displacement means arranged to displace the or each extinguisher between said flame supporting position and said flame extinguishing position; and an activator for said displacement means; in which said displacement means comprises a toothed pinion gear operatively connected with a toothed rack connected to said extinguisher; a stopping device moveable between a gear engaging position in which said stopping device engages said gear and a disengaged position in which said stopping device is disengaged from said gear; and biasing means arranged to bias said rack such that said extinguisher moves from said flame supporting position to said flame extinguishing position when said stopping device moves from the gear engaging position to the disengaged position; and where the activator is arranged to move the stopping device from the gear engaging position to the disengaged position when said activator is activated. In a further embodiment, said extinguisher is a snuff tube located around the or each wick holder, the snuff tube being slidably movable between the flame supporting position in which an upper portion of a wick held in the wick holder is exposed above the upper end of the snuff tube, and the flame extinguishing position in which the upper portion of a wick held in the wick holder is covered by the snuff tube, and wherein the combustion device further comprises a further tube located around the snuff tube and wick holder, the further tube being arranged to cover a bottom portion of the snuff tube when the snuff tube is in the flame extinguishing position to impede the flow of air from the exterior to the interior of the snuff tube around the bottom end of the snuff tube. |
