Description

 Satsuki Itoda · Liquid fuel combustion equipment Technical field

 The present invention relates to a liquid fuel combustion device such as a smoking device lighter, an igniter, and the like, which uses a liquid fuel mainly composed of alcohol, sucks and burns the liquid fuel stored in a fuel tank by a combustion wick by utilizing a capillary phenomenon. In particular, it relates to a structure in which a combustion wick and an ignition member are installed in the upper part of a fuel tank.

 Background art

 In general, as fuel for burning equipment such as ryuiichi for smoking equipment, igniters, torches, lighting equipment, heating equipment, etc., alcohol fuel such as ethyl alcohol, petroleum benzene-based benzene fuel including gasoline, butane gas, propane gas, etc. Of liquefied gas fuels are used.

 The performance, usability, and design structure of each combustion device differ depending on the type of fuel used, and each has its own characteristics.

 For example, in the case of benzene fuel using a mixture of petroleum benzene hydrocarbon compounds, this fuel is a mixture of compounds having different boiling points, and the benzene component having a low boiling point volatilizes in the early stage of use after ignition of a combustion appliance. The same applies to gasoline, in which volatile components move sequentially to hydrocarbons with higher boiling points, so that the fuel composition remaining in the combustion equipment changes according to the burning time, and this causes a change in flame length. In addition, benzene and gasoline have high volatility, and the combustion equipment that uses them requires a sealed structure that reduces volatilization from the fuel storage section and the combustion wick. The gas is volatilized and lost, the refueling frequency is high and complicated, and the benzene and gasoline have a peculiar smell and may not be preferred.

In the case of liquefied gas fuel, the gas pressure is high in the operating temperature range of the combustion equipment, and the container for storing the fuel must have a pressure-resistant structure. Further, the flame length changes in accordance with the fluctuation of the gas pressure. In particular, there is a characteristic that the gas pressure greatly changes logarithmically with respect to the temperature. In order to reduce this flame length change Special design measures to compensate the temperature of the fuel supply mechanism of the combustion equipment are required, which complicates the structure and is disadvantageous in terms of cost.

 On the other hand, in the case of alcohol fuels, liquid fuels mainly composed of alcohols such as lower alcohols such as ethyl alcohol, methyl alcohol, and plastic alcohol are liquids at room temperature, have relatively low vapor pressure, and can be used for fuel storage. A pressure-resistant container is not required, and the fuel tank and the combustion wick need to be hermetically sealed so that alcohol does not evaporate. This is advantageous in terms of simplification of the structure of combustion equipment and cost.

 In addition, in a combustion device using a liquid fuel other than a liquefied gas fuel, as a means for supplying the liquid fuel from the fuel tank to the combustion section, generally, continuous pores or liquids are formed using the surface tension of the liquid fuel. It uses a combustion wick that sucks up the gaps of bundled fine fibers by capillary action and burns at the tip. The tip of the combustion core is ignited by a spark using a igniter or a file wheel or by an ignition member that discharges using a piezoelectric element.

 As a fuel tank of such a liquid fuel combustion device, a container made of plastic or the like is used by being formed into a shape suitable for the purpose of use, and the combustion core is directly attached to a tank lid for closing the upper portion of the fuel tank. And an ignition member.

 However, in the above-described liquid fuel combustion device, when the combustion wick is ignited and burned, the temperature of the igniting member rises, and there is a possibility that poor holding of the igniting member may occur.

 In other words, if the ignition member is placed away from the combustion core, for example, the range of the spark will be longer and the ignitability will be reduced, and the ignition member will be arranged closer to the combustion core to ensure ignitability. It is necessary to do so, but the ignition member such as a file vehicle approaches the flame and the temperature rises accordingly. When the file wheel is heated, for example, the heat is transferred to the supporting portion of the tank lid formed of the plastic and the supporting portion is melted, and the file is dropped due to the pressing force of the igniter stone against the file wheel. Therefore, it is necessary to improve the heat resistance of the support part and the heat resistance of the holding part of the combustion wick.

In addition, when assembling the liquid fuel combustion equipment, the lower end of the combustion wick The upper end is provided so as to protrude through the tank lid of the fuel tank, but since the combustion wick and the batting contained in the fuel tank are flexible, the tank lid is fixed to the fuel tank. It is preferable to insert the wick together with the batting into the fuel tank before filling.In such a case, it is necessary to provide a through hole larger than the outer diameter of the wick to the tank upper lid, to insert the wick and attach the upper lid to the tank. At that time, it is necessary to fix the combustion wick simply and with good workability by an appropriate method.

 The present invention has been made in view of the above circumstances, and has as its object to provide a liquid fuel combustion apparatus which has improved heat resistance and assemblability in arranging a combustion core and an ignition member on a tank lid of a fuel tank.
