It is coupled to the outer circumferential surface of the ignition unit to significantly reduce the amount of external air introduced into the combustion tube when the ignition unit is pressed, so that the gas injected into the combustion tube can be easily ignited using the ignition unit, and the opening and closing unit The operation unit provided in the ignition unit is coupled to the outer circumferential surface of the ignition switch of the ignition means, and after the ignition operation is completed, a large amount of external air is introduced into the combustion pipe by opening the inlet hole where the opening and closing plate is blocked. Not only can it generate a strong flame, but also because the operation part constituting the opening/closing means is coupled to the ignition switch operated by pressing, the opening/closing plate has an opening/closing device for an ignition device that blocks the inlet hole only when the ignition switch is ignited. It relates to an installed gas torch.

In general, a gas torch is used to ignite charcoal fire, weed removal, wall blades, etc. by igniting the gas injected by being combined with a portable butane gas cylinder.

The gas torch consists of a case and a coupling hole coupled to the upper surface of the butane gas cylinder, a gas supply pipe coupled to the upper surface of the coupling hole, and a crater formed on the front of the gas supply pipe, as in the previously registered patent No. 10-1045873. It is roughly different.

The fixing hole is formed under the case, the gas supply pipe is coupled to the upper surface of the fixing hole so as to be located inside the case, and the crater is coupled to the front end of the gas supply pipe so as to protrude from the front of the case.

The control lever is installed at the rear of the case to be connected to the gas supply pipe so that the control lever controls the amount of gas injected into the crater, and an ignition button is installed at the bottom of the case. Ignite the gas that is injected into the inside of the unit.

That is, when the control lever is rotated in one direction while the torch is coupled to the upper surface of the butane gas using the binding hole, the gas contained in the butane gas is injected to the crater through the gas supply pipe.

When the gas is injected into the crater and the ignition button is pressed at the same time, electricity is generated in the spark plug provided inside the crater, and the gas injected into the crater is ignited and a flame is generated. It is possible to ignite a charcoal fire or a wall stove by using.

However, the problem with the conventional gas torch is that when the gas injected into the crater is ignited using the ignition button, there is no device for introducing external air into the crater, so the inside of the crater using a spark plug connected to the ignition button. There is a problem that it is not easy to ignite the gas injected into the air.

In addition, since the conventional gas torch does not allow external air to flow into the crater, in order to generate a strong flame in the ignited gas, a large amount of gas must be supplied into the crater, resulting in gas efficiency and waste of fuel. Was done.

In addition, in order to protect the ignition button that ignites the injected gas from the heat of the heated crater, it is necessary to implement a device in which the ignition button is installed in the case, and the structure of the gas torch is complicated, thereby increasing the manufacturing cost, thereby reducing productivity.

The ignition unit is formed on both sides of the connection unit, and when the ignition unit is pressed, an opening/closing means for blocking any one of the inlet holes formed on both sides of the connection unit is coupled to the outer circumferential surface of the connection unit while moving forward. When the means is pressed for ignition, the amount of external air introduced into the combustion tube can be significantly reduced, so that the gas injected into the combustion tube can be easily ignited using the ignition means. After completing the ignition operation by combining it with the outer peripheral surface of the ignition switch, a large amount of external air is introduced into the combustion pipe by opening the inlet hole where the opening and closing plate is blocked, so that a strong flame can be generated even if a small amount of gas is used. The purpose of this is to provide a gas torch equipped with an opening/closing device for an ignition device in which the opening and closing plate blocks the inlet hole only when the ignition switch is ignited. do.

When explaining the preferred operating state of the present invention configured in this way are as follows.

First, the torch body 1 having the gas supply pipe 4 formed thereon is coupled to the butane gas cylinder G as shown in FIG. 9 using the adapter 2.

When the torch body (1) is coupled to the butane gas cylinder (G), the user rotates the gas control handle (3) in one direction to open the inside of the gas supply pipe (4), so that the gas contained in the butane gas cylinder (G) Supply.

A technique of controlling the internal opening amount of the gas supply pipe 4 using the gas control handle 3 is a general technique, and a detailed description thereof will be omitted.

The gas supplied into the gas supply pipe 4 is supplied to the crater case 60 provided with the connection hole 71 through the nozzle hole 31 provided in the nozzle 20, and to the crater case 60. The supplied gas is supplied to the front end of the crater 5 and injects the gas into the combustion tube 6.

When gas is injected into the combustion tube 6, the user applies pressure to the operation part 122 of the opening/closing means 110 coupled to the outer circumferential surface of the ignition switch 140 constituting the ignition means 130. The ignition switch 140 is pressed and operated.

As the ignition switch 140 is pressed, the opening/closing body 120 coupled to the outer circumferential surface of the nozzle 20 as shown in FIG. 6 (a) moves to the left as shown in the drawing, and on one side of the opening/closing body 120 The formed opening and closing plate 121 blocks the inlet hole 91 formed in the connection unit 10.

At the same time as the inlet hole 91 is blocked, the ignition switch 140 causes a spark to be generated in the spark plug 142 coupled to one side of the crater 5 to ignite the gas injected into the combustion tube 60.

At this time, it is revealed that the ignition switch 140 and the spark plug 142 constituting the ignition unit 130 are connected by an electric wire 141 as shown in FIGS. 6A and 6B.

When the gas injected into the combustion tube 60 by the ignition means 130 is ignited, the user removes the pressure applied to the operation unit 122.

At the same time as the pressure applied to the operation part 122 is removed, the ignition switch 14, which is energized by the spring (not shown), moves to the right in the drawing, which is the initial state as shown in FIG. 5(a), while opening/closing means ( The operation unit 122 of 110) is returned to the initial state.

Since the operation part 122 returns to the initial state, the opening/closing plate 121 is moved to the right as shown in FIG. 5, and the blocked inlet hole 91 is opened to generate a flame by the ignition means 130. It is possible to continuously supply external air to the inside of the combustion tube 6.

In this way, the ignition means 130 is provided, and the opening/closing means 110 is installed on the outer circumferential surface of the connection unit 10 provided with inlet holes 91 on both sides, so that the opening/closing means for the ignition operation of the ignition means 130 ( Since the opening/closing plate 121 constituting 110 blocks the inlet hole 91 of any one of the inlet holes 91 formed on both sides, the gas injected into the combustion tube 6 can be easily ignited. The effect can be expected.

In addition, after the ignition means 130 is gas ignited, due to the ignition switch 140 of the opening/closing means 130, which is restored to the initial state, the opening/closing plate 121 opens the blocked inlet hole 91 to a large amount. Since the external air of the gas is introduced into the interior of the combustion tube 91 through the connection hole 91, even if a small amount of gas injected into the interior of the combustion tube 6 is used, a strong thermal power can be generated. It can be expected the effect that can prevent wasted.
