This condensed fuel not only penetrates between the shielding plate 5 and the fire pan 2 and wets the lower surface of the shielding plate 5, but also flows out from the gap between the lower end of the combustion chamber 3 and the shielding plate 5 to the upper surface of the shielding plate 6. Sometimes. At this time, when the shielding plate 5 is slid and shielded to extinguish the fire, the tip of the lamp wick 1 becomes almost sealed and the fire is extinguished, but the fuel that has condensed on the upper surface of the shielding plate 5 re-vaporizes and the combustion chamber is still in a high temperature state. 3, and is partially oxidized while being heated and decomposed to become malodorous substances such as aldehydes, which generate a significant odor. In addition, condensation on the lower surface of the shield plate 5 is caused by a minute gap between the shield plate 5 and the combustion chamber 3 (this gap can easily occur due to thermal deformation of the heat shield plate 5 or the combustion chamber 3). The re-vaporized fuel gas and the late-vaporized fuel gas from the tip of the lamp wick 1, which is still in a high temperature state, flow into the combustion chamber 3, producing a foul odor as described above. In this way, even when the upper part of the lamp wick 1 is closed with the shielding plate 6,
This method has the disadvantage that it is not possible to completely suppress the generation of bad odors when extinguishing a fire.
