JPH077312Y2 - Windproof candle - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The range of outdoor use has been expanded.

[Prior Art] Previously, there was only a wick that was a combination of cotton thread, fabric, shaft and cotton thread, and it was weak against the wind.

[Problems to be solved by the invention] In a conventional candle, the flame was easily blown out in the wind. The reason for this is that the wick is made of cotton or cloth, and the temperature of the burning part drops with a little wind, and the wax does not evaporate.

Therefore, we considered a structure in which the temperature of the wick is unlikely to drop.

[Means for Solving the Problem] In order to solve this problem, a combination of a cotton thread and a shaft made of wood or bamboo was considered. However, simply arranging them in parallel would cause the stem to protrude into the combustion section, which would rather hinder combustion.

Then, we devised a structure in which the circumference of a tree or bamboo shaft was directly covered with a Japanese paper or cotton core material. In this way, by bringing the stem to the center of the core, the stem does not interfere with combustion, and at the same time the stem carbonizes and acts as a charcoal fire, stabilizing the temperature of the burning part. . This created a candle that wouldn't disappear in a little wind.

There are wood, bamboo and briquettes as the material of the shaft. As the core material,
Paper, cloth, and cotton are good because they absorb wax and burn it.

[Operation] The reason why the candle disappears is that the temperature of the combustion section drops. Since it was very difficult to maintain the temperature of the burning part when the wind blows only with the cotton thread and the core material of the cloth, the fire was extinguished immediately.

When the wick of the present invention is used, when the wind blows, the carbonized part of the shaft of the central part becomes a charcoal fire and becomes red hot, so it prevents the temperature drop in the combustion part and reduces the flame, You can keep burning.

It was also found that with the existing combination of shaft and cotton yarn, since they are only arranged in parallel, the shaft interferes with combustion and such an effect does not occur.

[Effect of the invention] Even if a windproof candle is used as a light for visiting a grave, it often burns to the end. Even when I used it at the camp, the candle kept burning even if the normal candle disappeared.
