Description

  The present invention supplies a liquefied gas remaining in a fuel storage tank to an ignition nozzle in a gas lighter that is used by igniting a gas ejected from the tip of an ejection nozzle through a valve mechanism from a fuel storage unit. It relates to a structure that can.

  Conventionally, a tank for storing liquefied gas and a liquefied gas for fuel from the tank are vaporized, and a burner nozzle for forming a flame and an ignition means for supplying an ignition spark to the vaporized gas ejected from the burner nozzle Gas igniters are well known and widely used as home gas stove igniters and cigarette ignition gas lighters.

  The tank for storing liquefied gas is a pressure-resistant container usually made of synthetic resin or metal. A burner nozzle is attached to the upper part of the tank, and the liquefied gas in the tank is a suction core extending downward from the burner nozzle. While the gas is sucked up and vaporized by the burner nozzle, vaporized gas is ejected from the tip of the nozzle and ignited by ignition means to create a flame.

  The suction core that sucks up the liquefied gas is made of a rod-shaped material such as a porous core member, for example, a polyethylene sintered body or a polypropylene sintered body, and is relatively easy to break. The lower end of the suction core does not reach the inner bottom surface of the tank, but ends slightly away from the inner bottom surface.

  Since the lower end of the suction core does not reach the inner bottom surface of the tank, the remaining amount of liquefied gas in the tank decreases. When the suction core is exposed from the liquefied gas, it is no longer easy to suck up the liquefied gas. Even though the liquefied gas remained in the tank, it was impossible to ignite and it was impossible to create a flame.

  Even if the lower end of the suction core is exposed above the liquefied gas remaining in the fuel tank, this device enables the liquefied gas to be effectively sucked up and absorbed by a very simple mechanism, and the liquefied gas remains. Nevertheless, it is intended to eliminate the inconvenience that makes ignition impossible.

  In order to solve the above-mentioned problems, the means taken by the present invention is that a porous cylindrical body capable of sucking and absorbing liquefied gas is sucked into a porous suction core connected to a burner valve. The liquefied gas sucked up and absorbed by the cylindrical body by the contact between the cylindrical body and the suction core is transferred to the suction core.

  The cylindrical body may be a rigid body, a flexible body, or a soft body.

  According to this device, even when the amount of residual liquefied gas in the fuel tank becomes small and the suction core is not in contact with the liquefied gas, the cylindrical body inserted into the suction core has a small amount of residual liquefaction. A conventional gas that cannot be ignited even though the liquefied gas still remains in the tank because it can be immersed in the gas and sucked and absorbed by the liquefied gas and transferred to the wick. It is possible to eliminate the problem of the ignition tool.

  A preferred embodiment of the present invention will be described in detail below. Referring to FIG. 1, (1) is an igniter body having a long ignition branch pipe (2) suitable for igniting a gas stove, a candle, a gas stove, etc. As shown, a flame for ignition is created from the tip of the ignition branch (2). Although the illustrated embodiment has a structure suitable for igniting a gas stove, a candle, and a gas stove, it should be understood that an ignition device such as a gas lighter for igniting a cigarette may be used.

  In the ignition device main body (1), there are a fuel tank (3) incorporating a burner valve (4), a piezoelectric generator (5), opening / closing of the burner valve and an operation button (6) for operating the piezoelectric generator. An ignition mechanism is incorporated. Note that the present invention can be similarly applied to an igniter that does not have a piezoelectric generator, for example, an igniter that includes an ignition mechanism made of an ignition file or an ignition stone, and the ignition means is not limited.

  An ignition nozzle (8) is disposed in the vicinity of the tip opening (7) of the ignition branch pipe (2), and is connected to the burner valve (4) by a fuel pipe (9). In addition, the metal coil (10) disposed in the vicinity of the tip of the ignition nozzle and the ignition nozzle (8) lead the lead wire (11) to the piezoelectric generator (5) so that an ignition spark is formed therebetween. ).

  The operation button (6) can be pushed down by a distance (L) by inserting a finger from the outside of the ignition device body (1). By pressing the operation button (6), the lever member (12) for opening and closing the burner valve (4) is operated, the burner valve (4) is opened, and the piezoelectric generator (5) is operated to Is generated. Gas vaporized by opening the burner valve (4) is guided to the ignition nozzle (8) through the fuel pipe (9), and the generated piezoelectric electricity is connected to the metal coil (10) and the ignition nozzle through the lead wire (11). (8), an ignition spark is generated, the vaporized gas is ignited, and a flame (13) is created from the tip opening (7).

A concave portion (14) for mounting the piezoelectric generator (5) is provided on the side portion. A suction core (15) extends from the burner valve (4) toward the fuel tank (3). The suction core (15) terminates slightly above the bottom of the tank.

  The suction core (15) is made of, for example, a porous rod-shaped material obtained by sintering high density polyethylene (HDPE) or polypropylene, and is immersed in a liquefied gas stored in the fuel tank (3) to be liquefied. The gas is sucked up and absorbed and transferred to the burner valve (4). The suction core (15) is a single rod-like body that extends substantially in a straight line and easily breaks. Therefore, the suction core (15) is formed with a length that ends away from the bottom surface of the fuel tank (3). Has been.

  Conventionally, when the amount of liquefied gas remaining at the bottom of the fuel tank (3) decreases, the suction core (15) is not immersed in the liquefied gas, so that a small amount of liquefied gas remaining at the bottom of the tank is sucked up. could not. Therefore, in this invention, a porous cylindrical body (16) is inserted into the suction core (15) so as to be movable up and down along the core, and the cylindrical body (16) is converted into the liquefied gas remaining at the bottom of the tank. Immerse and absorb and absorb liquefied gas.
