Abstract

PROBLEM TO BE SOLVED: To hold a core and prevent it from falling off while providing a gap between the inner wall of the core holder and the core so as to alleviate carbonization of the core due to combustion and maintain vaporization of oil from the core even if carbonization progresses. A core holder for oil candles with an internal shape like this. SOLUTION: A space of an inverted truncated cone is provided inside the lead holder to secure a gap between the lead and the inner wall of the lead holder, and an oil from the lead is provided while holding a lead by providing an elliptical cylindrical lead holding space at the lower part thereof. It was made not to inhibit the vaporization. [Selection] Figure 2

Description

  The present invention relates to a lead holder for an oil candle that is designed to reduce carbonization at the tip of the lead.

  In an oil candle using a conventional lead holder, if waste cooking oil is used as fuel, the progress of carbonization at the tip of the lead is remarkable, and the flame is reduced and disappears. This phenomenon is because waste cooking oil contains impurities that are not contained in the new oil. Even when oil containing impurities such as waste edible oil is used as a fuel, there is a need for an oil candle core holder in which carbonization of the core tip is difficult to proceed and a constant combustion state can be maintained even if it progresses.

  There are documents 1, 2, and 3 in the literature related to the core holder for the conventional oil candle, but the shape of the portion where the core is mounted is usually a cylindrical shape, and attention is not paid. That is, there is no description regarding the internal shape. The reason why the internal shape of the conventional core holder is normally a cylinder is that it is not necessary because it uses a fuel exclusively for oil candles that does not contain impurities.

When waste cooking oil is burned using a conventional core holder, the progress of carbonization at the core tip is significantly faster than new oil. This is because waste cooking oil contains many impurities. If the carbonization at the tip of the core reaches the entire core protruding from the core holder, the flame becomes smaller and disappears.
The mechanism by which oil burns is that the temperature rises above the flash point and ignites when the spark comes close to the oil that has reached the tip of the core due to capillary action. The flame stops at the tip of the wick because it is cooled by the wick holder. The role of the wick is to suck up the oil by capillary action and to change the oil into a flammable gas. If there is no gap between the holder and the core, the function of vaporizing the oil is impaired and carbonization tends to proceed. Also, if the part protruding from the core holder is covered with carbon, the oil cannot be vaporized and disappears. It is necessary to provide a gap between the inner wall of the core holder and the core in order to change the oil to a combustible gas and to maintain the combustion even if carbonization at the tip of the core proceeds. By providing the gap, the oil can be continuously vaporized from the core. On the other hand, if the gap is provided, the core cannot be held, and the core falls out of the core holder.

  The present invention provides a core holder for an oil candle having a structure that simultaneously satisfies two contradictory functions of providing a gap between the inner wall of the core holder and the core and holding the core so as not to come off. With the goal.

  FIG. 1 is a schematic diagram showing the state of the wick during combustion. In order from the tip, there are a portion A that has been carbonized black, a portion B that has been blackened due to the progress of carbonization, and a portion C that has not lost its function of vaporizing oil, and a portion C that vaporizes oil by the color of the core itself. If combustion is continued, carbonization starts from the tip and proceeds to the lower part of the core. In order to continue combustion, the part C that vaporizes oil is necessary, but if there is no gap between the core and the core holder, the C part disappears due to the progress of carbonization, and the function of vaporizing oil is lost. .

FIG. 2 is a vertical sectional view of the core holder 1 passing through the central axis 2 parallel to the direction of gravity. Inside the lead holder to which the lead is attached, there is a vaporization space 3 for vaporizing the oil and a holding space 4 for holding the lead at the lower part so as not to fall off. The vaporization space is an inverted truncated cone. The holding space is an elliptic cylinder.
FIG. 3 is a vertical cross-sectional view when the lead is mounted on the lead holder. By making the vaporization space an inverted truncated cone, a gap 6 is generated between the inner wall and the core while holding the core.

  FIG. 4 is a horizontal sectional view of the vaporization space (D-D ′ section in FIG. 3). The cross section of the vaporization space is circular, and the gap is a concentric circle about the axis of the core holder. By making the gaps concentric, the oil vaporization becomes uniform, and a flame of the target shape is obtained on the shaft.

  FIG. 5 is a horizontal sectional view of the holding space (E-E ′ section in FIG. 3). The cross-sectional shape is an ellipse. The minor axis of the ellipse is smaller than the outer diameter of the core and holds the core. The major axis of the ellipse is larger than the outer diameter of the core, and there is a gap between the core holder inner wall and the core. By holding the core on the short axis side of the elliptical shape and securing a gap on the long axis side, the vaporization of oil from the core is not inhibited while the core is held.

  As described above, the core holder for an oil candle according to the present invention can be burned with a certain flame even when oil containing many impurities such as waste cooking oil is used as a fuel by providing a gap between the inner wall of the holder and the core. It can last. In addition, the core can be held while providing a gap.

  When the present invention is used as an oil candle, a dedicated candle core or cotton octopus thread is attached. The thickness of the core is adjusted to the length of the short axis of the elliptical cross section that holds the core. Pass the lead through the lead holder and select a lead with a diameter that produces a light frictional force. The replacement core is easy to pass if the tip is hardened with an adhesive and made thin. When mass producing the lead holder, the lead holder dimensions are determined in accordance with the lead standard.

  FIG. 6 is a diagram showing an embodiment of the present invention. The lead holder of the present invention is fixed vertically to the stand. Attach the lead to the lead holder and place it on the bottom of the glass container so that the tip of the lead comes to the center of the container. Pour the oil onto the tip of the lead so that the liquid level is about 10 mm below the tip of the lead holder. When a flame such as a gas igniter is brought close to the tip of the lead and ignited, the flame 13 is lit. When extinguishing fire, cover with a metal lid and cut off oxygen.

  The present invention contributes to the effective utilization of waste cooking oil from here where waste cooking oil containing a large amount of impurities can be used as fuel for candles.
