Abstract

PURPOSE:To ensure ignition of fuel of a gas lighter even under a strong wind and prevent the flame from being blown out thereby by a construction wherein the windshield of the lighter has a notch formed on a side surface thereof and the lower part of the notch swells out towards a nozzle thereby forming an upwardly directed draft passage. CONSTITUTION:A windshield 1 has a front wall 1C formed with a notch 1e, and the lower part of the notch 1e swells out towards a nozzle 6 thereby forming a draft passage within the windshield 1. When the lighter is clicked to flame, the combustion air flows through the air inlet port 1e and thence through the draft passage in the generally same direction as the flame of the lighter and into a flame nozzle 1d. At that time, the air flowining in the windshild through the air inlet port 1e is intercepted by the swelled part so that the air is not allowed to impinge directly against the nozzle 6. Therefore, a stable flame can be obtained and there is no anxiety of the flame being blown out even under a strong wind.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement of Gasly 2, particularly 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 conventionally known ones had the following problems:

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

The present invention was made from the viewpoint of ridges, and its purpose is to prevent heat conduction to the file and file wheel, and to prevent flashlight after extinguishing.
To provide a gas lighter equipped with a windshield that can reliably ignite even outdoors with strong winds or indoors where 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 notch in the side surface of the member that forms the windshield of the gas lighter, and making the lower part of the notch bulge toward the nozzle side, an upward ventilation path is formed within the windshield. There is something to do.

Hereinafter, the crushing 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 broken explanatory view thereof, and FIGS. FIG. 7 is an explanatory diagram showing another shape of the ventilation passage formed by bulging the lower part toward the nozzle side.

In Figures 1, 1112 and j83, 1 is the windshield, 1a is the top wall, lb, lb are the side walls, IC is the front wall, 1d is the crater provided on the top wall 1a, and 1e is the front wall 1c. A ventilation hole is formed by making a notch and expanding the lower part of the notch toward the nozzle, 2, 1 file wheel, 3 file auxiliary car, 4 file shaft, 5 flint, 6 nozzle, 7 nozzle It is an adjustment ring.

Therefore, the windshield 1 has a top surface 1!18% left and right side walls 1b, 1
b and a front wall 1c, the upper wall 1a is provided with a crater 1d, and the front wall 1c is provided with a ventilation hole 1e. Ventilation port 1e is made by cutting a notch in the front wall IC,
After that, it is manufactured by expanding the lower part of the cut toward the nozzle 6 side. As a result, a ventilation path is formed within the windshield 1 from the ventilation port 1e toward the crater 1d provided in the upper wall 1a.

Then, rotate the file wheel 2 using the file auxiliary car and release the flint stone 5.
When the gas ejected from the nozzle 6 is ignited, the air necessary for combustion is supplied from the ventilation port 1e.
The air that is also supplied is supplied through the above-mentioned ventilation passage formed in the ventilation opening le. 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 801e does not directly hit the front part of the nozzle 6, so a stable flame is obtained. Moreover, even if it is used in a windy place, it will not be blown away by the wind.

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

Figure 1 of Figures 4, 5, 6, 7 and 8,
The same numbers as those in Figures 2 and 3 indicate the same components, 1e-1 and 1e-2.
is a ventilation hole provided in the side wall 1b11b.

Therefore, the illustrated gas lighter has a ventilation hole in the windshield on the front wall 1.
This is provided not only in the side walls 1b and 1b, but also in the side walls 1b and 1b.
The ventilation passage formed by e-1 and 18-2 can supply sufficient and necessary air for combustion of gas, and is also supplied from each ventilation port 1e, io- and 1e-2. Since the air can be made to match the combustion direction of the flame 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. However, the same effect can be obtained even if the shape is bulged inward as shown in FIGS. 6, 7, and 8.

Since the present invention is structured like a ridge, when using the present invention, it is possible to prevent heat conduction to the file and file wheel, etc., and to prevent fireflies after extinguishing the fire, as well as to prevent windy outdoors or using an electric fan, etc. 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 embodiment on ridges. That is, for example, in this embodiment, a notch is made in the side surface of the member forming the windshield, and the lower part of the notch bulges toward the nozzle to form an upward ventilation path within the windshield. The windshield may be provided with a ventilation hole similar to that of a conventional gas lighter, and the nozzle adjustment ring may be provided with a windbreak plate having a shape that surrounds the nozzle tip and forms a ventilation passage as in the present invention. The shape, number, etc. of the membrane can be freely changed within the scope of the purpose of the present invention, and the present invention encompasses all of them.
