Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas lighter, and particularly to an improvement of its windshield.

There are two types of gas lighters: cheap disposable ones and ones that can be refilled with gas and used repeatedly.Also, there are those for smoking and those for other purposes, but there are conventionally known ones. had the following problems.

The problem is that the windshield of conventional gas lighters is effective in preventing heat transfer to the file and file wheel, and in preventing so-called flashfires, where small flames remain on the nozzle after extinguishing. The function of blowing out does not fulfill its original function, and it is difficult to catch fire especially outdoors in strong winds or indoors where a fan is used, and even if a fire does start, it will quickly blow away It was blown out by the fire and I felt unwell.

The present invention has been made based on the above-mentioned viewpoints, and its purpose is not only to prevent heat conduction to the file and the file wheel, but also to prevent flashlight after extinguishing the file, as well as to prevent To provide a gas lighter equipped with a windshield that can ignite reliably even outdoors or indoors when a fan or the like is used, does not blow out, and keeps the flame extremely stable.

The gist of this is that by making a cut in the side of the member that forms the windshield of the gas lighter,
By bulging out the lower part of the cut toward the nozzle side, an upward ventilation path is formed within the windshield.

Hereinafter, the details of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the windshield portion of a gas lighter according to the present invention, FIG. 2 is a top view thereof, FIG. 3 is a partially cutaway explanatory view thereof, and FIG. A perspective view showing an example of another windshield part, FIG. 5 is a top view thereof, FIG. 6 is a partially cutaway explanatory diagram thereof, and FIGS. FIG. 7 is an explanatory diagram showing another shape of the ventilation passage formed by expanding the lower part of the cut toward the nozzle side.

In Figures 1, 2 and 3, 1 is a windshield, 1a
is the top wall, 1b, 1b are the side walls, 1c is the front wall,
1d is a crater provided in the top wall 1a, 1e is a ventilation hole formed by making a notch in the front wall 1c and bulging the lower part of the notch toward the nozzle side, 2 is a file wheel, 3 is a file auxiliary car, 4 is the file shaft, 5
is a flint, 6 is a nozzle, and 7 is a nozzle adjustment ring.

Therefore, the windshield 1 has a top wall 1a and left and right side walls 1.
b, 1b and a front wall 1c,
A crater 1d is provided on the top wall 1a, and a ventilation port 1e is provided on the front wall 1c. The ventilation hole 1e is manufactured by making a notch in the front wall 1c, and then expanding the lower part of the notch toward the nozzle 6 side. Due to this, inside the windshield 1, the ventilation hole 1e
A ventilation path is formed from the vent toward the crater 1d provided in the upper wall 1a.

When the file wheel 2 is rotated by the file auxiliary vehicle and the gas ejected from the nozzle 6 is ignited by the flint 5, the air necessary for combustion is supplied from the ventilation port 1e; The air that is
The air is supplied through the above-mentioned ventilation passage formed in the ventilation opening 1e. That is, this air supply path coincides with the combustion direction of the flame of the ignited gas lighter, and the air supplied from the ventilation port 1e does not directly hit the front part of the nozzle 6, so that a stable flame can be produced. Moreover, it will not be blown away by the wind when used in a windy place.

Next, FIG. 4, FIG. 5, FIG. 6, FIG. 7, and FIG. 8 will be explained.

In Figures 4, 5, 6, 7, and 8, the same numbers as those in Figures 1, 2, and 3 indicate the same components. 1e-1 and 1e-2 are side walls 1b and 1, respectively.
This is a ventilation hole provided in b.

The illustrated gas lighter has ventilation holes in the windshield not only on the front wall 1c but also on the side walls 1b, 1b, and with this configuration, each ventilation hole 1e, 1e-- The ventilation passage formed by 1 and 1e-2 can supply the necessary and sufficient air for the combustion of gas, and can also supply the air supplied from each ventilation port 1e, 1e-1, and 1e-2. Since the combustion direction of the gas lighter flame can be made to match the combustion direction of the gas lighter, the flame can be maintained even more stably.

Note that the shape of the ventilation passage formed by making a cut in the windshield and making the lower part of the cut bulge toward the nozzle 6 side is a shape in which the windshield 1 is curved and bulged inward as shown in FIG. Not limited to only those of
Similar effects can be obtained by bulging inward in the shapes shown in FIGS. 6, 7, and 8.

Since the present invention is constructed as described above, the present invention not only prevents heat conduction to the file and file wheel, etc., but also prevents fireflies after extinguishing the file, and also prevents the use of windy outdoors or using an electric fan. This makes it possible to reliably ignite a flame even in a room where the flames are bright and not blow out, and to keep the flame extremely stable.

Note that the present invention is not limited to the embodiments described above. That is, for example, in this example,
A notch was made in the side surface of the member forming the windshield, and the lower part of the cut was bulged toward the nozzle to form an upward ventilation path within the windshield. The nozzle adjustment ring may be provided with a windbreak plate having a shape that surrounds the nozzle tip and forms a ventilation path as in the present invention, and the shape, number, etc. of the ventilation holes are also within the scope of the present invention. The design can be freely changed within the scope of the present invention, and the present invention encompasses all of them.
