DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the storage of liquid fuel in a lighter fueled with a liquid such as alcohol or hexane-based fuel such as petroleum or naphtha.

[0002]

2. Description of the Related Art A lighter which is ignited and burned by using an ignition means for generating a spark in a liquid fuel such as hexane-based petroleum or alcohol is a porous material such as an open-cell foam in a fuel tank containing the liquid fuel. A porous member or a fibrous member containing a cotton member or a felt material and a porous member or a fibrous member accommodated in a fuel tank, and the liquid fuel in the fuel tank is contained in the porous member or the fibrous member. The fuel moves and penetrates into the core member brought into contact with the porous member or the fibrous member, the fuel is guided by the core member to the ignition combustion portion on the fuel tank side, and the spark of the ignition means arranged near the end of the core member outside the fuel tank. Thus, the fuel of the core member is ignited to form a flame.

The present inventor has previously registered utility model registration No. 304.
No. 1467, the fuel tank of the liquid fuel lighter is composed of a main tank and a spare tank, and the main tank contains a liquid fuel suction core and a porous member or a fibrous member carrying the liquid fuel, and the spare tank is a main tank. A reserve fuel chamber is formed above the bottom of the main body provided with a liquid fuel filling section and a filling section closing lid at the bottom, and a first opening provided in a partition wall between the main tank and the main tank at the time of filling the liquid fuel is a main tank. A second opening is formed in the partition between the spare tank and the main tank, and the opening is formed so as to be always closed by a valve body. A novel liquid fuel lighter has been proposed in which an operation member provided on the body is followed by a pressing operation from outside the main body, the valve body is released, and the liquid fuel in the spare tank flows into the main tank.

[0004]

The conventional liquid fuel lighter has a structure in which the liquid fuel in the fuel tank is impregnated and supported on a fibrous member such as a porous member or felt having continuous cells. By reducing the volume of the liquid material storage section in the fuel tank by storing a fibrous member such as a porous member or felt of open cells that impregnate and carry the liquid fuel, and impregnating the porous member or the fibrous member with the liquid fuel The carrying capacity of the fuel tank is reduced, so that the number of times of ignition and combustion by one liquid fuel replenishment is reduced, and the frequency of refueling the fuel tank is increased.

[0005] When replenishing the fuel in the fuel tank, if the liquid fuel is filled to a capacity greater than the fuel impregnating capacity or the space volume of the porous member or the fibrous member such as felt, etc., of the open cell filled in the fuel tank, the suction core There were also problems such as leakage of liquid fuel and rapid change of combustion flame during combustion.

In the liquid fuel lighter proposed in Utility Model Registration No. 30441467, the formation of a reserve tank containing liquid fuel above the bottom of the main body having the main tank and the movement of fuel from the reserve tank to the main tank are not performed. The structure is complicated by the operation of the connecting valve built in the spare tank, and the liquid stored in the spare tank is provided because the spare tank is provided in a part of the main tank and the valve mechanism is built in the spare tank. Fuel storage capacity was sometimes limited.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an independent fuel tank containing only a liquid fuel which has the largest fuel storage capacity and can be discharged. The fuel take-out part of the fuel tank impregnated and loaded with the liquid fuel comes into contact with the fuel suction wick leading to the combustion part to supply the fuel to the combustion part. It is to provide a liquid fuel lighter with high stability.

[0008]

The fuel tank is provided with an opening for fuel injection and a lid for closing the opening, and an upstream side of a fuel sucking member communicating with the combustion section, and a fuel tank provided independently. In the opening at one end Fuel retaining member is disposed between the fuel tank outside of the wearing fuel suction-impregnation member,
One end of the fuel holding member is in contact with the upstream side of the fuel sucking member communicating with the combustion section, and the other end of the fuel holding member is on the outside of the fuel sucking / impregnating supporting member inserted into the opening of the fuel tank. A fuel suction core is formed on the inner wall side of the cylindrical body, one of which is suspended in the fuel tank, and the other which is capable of supplying fuel from the fuel suction core and serving as an outer portion of the tank is impregnated with fuel. In some cases, a member having a supporting structure is inserted and the outer wall side of the cylindrical body is detachably inserted into an opening at one end of the fuel tank.

[0009]

The liquid fuel is injected from an opening provided at one end of a fuel tank containing the liquid fuel, and one is impregnated with the liquid fuel sucked up by a fuel sucking wick suspended in the fuel tank on the other. The upper part of the fuel sucking / impregnating support member to be carried is attached by the inner wall of the cylinder, the outer wall of the cylinder is inserted into the opening provided at one end of the fuel tank, and the liquid fuel in the fuel tank is It is sucked up by the suction wick hanging down from the body and guided to the liquid fuel impregnated support member measured in the cylinder. Since the liquid fuel is contained only by liquid without being impregnated and supported on a fibrous member such as an open-cell porous member or felt, the internal volume of the fuel tank is effectively used as a pure fuel tank, and the liquid fuel is an independent fuel. Since the opening accommodated in the tank is only the cylindrical part into which the fuel sucking / impregnating support part inserted into the opening provided at one end of the fuel tank is inserted, fibers such as open-cell porous members and felts Evaporation of the liquid fuel is suppressed as compared with a case where a member having a large surface area such as a member is impregnated and supported.

The fuel tank containing the liquid fuel is mounted on a main body having a fuel tank holding section and a combustion section, and a liquid fuel impregnated support member inside the cylinder inserted into an opening at one end of the fuel tank is provided on the main body. The liquid fuel in the fuel tank comes into contact with the upstream side of the fuel sucking member leading to the combustion portion, is guided to the combustion portion, and is sucked up by sparks generated by ignition means provided near the end of the fuel sucking member in the combustion portion. The fuel near the core end is ignited to form a combustion flame.
