Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a cigarette lighter.

(Prior Art) Conventionally, with lighters that have a glowing body for ignition inside the outer case, it is necessary to look over the ignition hole or tilt the lighter in order to check the glowing state. The disadvantages were that it was troublesome and that the flames were directed towards the user, making it dangerous.

Therefore, in order to solve this drawback, the present applicant proposed a method in the previous application (Utility Application No. 63-69044) in which the flame is ignited by the same flame inside the outer case so that the flame surrounds the space in which the flame is ignited. The present invention proposes a lighter in which a hood with a luminous property is provided, an air intake hole is opened at a location facing the hood on the peripheral wall of the outer case, and the hood can be viewed through the air intake hole.

(Problem that the invention aims to solve) However, the air intake hole provided in the exterior case should not be too large in order to prevent dust from entering, so it is easy to see the hood through this air intake hole. However, it was still unsatisfactory in terms of ease of use.

Therefore, the present invention aims to provide a lighter that is safe, eliminates the need to look over the ignition hole or tilt the lighter to check the red-hot state, is safe, and is easy to use and allows the user to easily check the red-hot state. purpose.

(Means for Solving the Problems) In order to achieve the above object, the lighter of the present invention has a red-hot ignition body 1 disposed above the gas combustion space and a hood 2 that turns red as the red-hot ignition body 1 glows. Arranged to surround the gas combustion space,
A window hole 5 separate from the air intake hole 4 is formed in the outer case 3 that houses the hood 2 on the peripheral wall facing the hood 2, and a transparent wall member 6 is fitted into the window hole 5. That is.

In order to enhance the visual effect by diffusing the light passing through the transparent wall member 6, the inner surface of the transparent wall member 6 is provided with a large number of curved surfaces, and the outer surface thereof is provided with minute irregularities in the shape of frosted glass. Good too.

(Function) A window hole 5 is opened in the peripheral wall of the exterior case 3 facing the hood 2 which turns red with the red heat of the red-hot igniter 1, and the light-transmitting wall member 6 is fitted into the window hole 5. By observing the reddened hood 2 from the member 6, the red-hot state of the red-hot igniter 1 can be easily recognized.

(Example) An example will be described with reference to the drawings. First, a fuel gas supply pipe 10 having a built-in valve (not shown) that is opened and closed by an opening/closing rod 9 that interlocks with the opening/closing lid 8 is connected to one end of the upper surface of the fuel tank 7, and a fuel gas supply pipe 10 is connected to one end of the upper surface of the fuel tank 7. A piezoelectric ignition device 12 is attached to the side end of the piezoelectric ignition device 12, which emits sparks from the electrode 11a when the opening/closing lid 8 is pressed down by the opening force. A vaporizing pipe 14 having a vent hole 13 on its peripheral wall is connected to the upper end of the fuel gas supply pipe 10, and a nozzle member 16 having a gas ejection hole 15 is provided at the upper end of the vaporizing pipe 14.
A cylindrical hood 2 made of translucent and heat-resistant ceramic is placed over the upper end of the vaporizer tube 14 so as to surround the space above the nozzle member 16, and a cylindrical hood 2 is inserted into the hood 2 and penetrates through its side wall. The electrode 11a of the ignition device 12 is attached.

Further, a dish-shaped dust-proof body 17 having a raised portion 17a along the peripheral wall is attached to the outer peripheral portion of the vaporizing tube 14 at a position below the hood 2. A support 18 is provided between the ignition device 12 and the fuel gas supply pipe 10 on the upper surface of the fuel tank 7, and an exterior case head member 3a that constitutes the exterior case 3 together with an exterior case main body member 3b (described later) is attached to the support 18.
is fixed by a stop pin 19, and the above-mentioned opening/closing lid 8 is also rotatably attached by the stop pin 19. An ignition hole 20 is provided at a position directly above the above-mentioned hood 2 on the top surface of the exterior case head member 3a, and a ring frame 21 to which a coiled red-hot igniter 1 is fixed is fitted inside the ignition hole 20. As shown in FIG. 3, a window hole 5 having a U-shaped cross section is provided in the peripheral wall of the exterior case head member 3a that surrounds the upper half of the hood 2, and a heat-resistant plastic transparent material is provided in the window hole 5. A light wall member 6 is fitted. As shown in FIG. 4, this light-transmitting wall member 6 has a large number of curved surface portions 6a in the form of vertical stripes (wavy in the horizontal direction) on its inner surface, and minute irregularities (irregularities in the shape of frosted glass) on its outer surface. (shown as dots in Figure 4). The outer case body member 3b accommodates the fuel tank 7, fits into the outer case head member 3a, and is fixed to the bottom surface of the fuel tank 7 with screws 22. An air intake hole 4 is formed in the peripheral wall of the outer case main body member 3b at a position facing the rising portion 17a of the shell body 17 attached to the vaporizing tube 14.

When the opening/closing cover 8 is pressed down, the opening/closing rod 9 will open as shown above.
The valve of the fuel gas supply pipe 10 is opened, and the fuel gas discharged from the fuel tank 7 flows into the vaporization pipe 14 , where it flows through the air intake hole 4 and enters the body 17 .
After passing through, the gas is mixed with air taken in from the vent hole 13 and is ejected from the gas ejection hole 15 of the nozzle member 16 into the hood 2 . On the other hand, at the same time,
When the opening/closing lid 8 is pressed down, sparks are discharged from the electrode 11a of the piezoelectric ignition device 12 toward the other electrode 11b similarly attached to the opposite side wall of the hood 2, and the fuel gas in the hood ignites and burns. Due to the combustion, the red-hot igniter 1 becomes red-hot, and by touching the tip of the cigarette to the red-hot ignitor 1, the cigarette can be ignited. Red light generated by red-hot igniter 1 passes through hood 2,
Furthermore, the user can see the red-hot state through the transparent wall member 6 located on the outer periphery.

As mentioned above, the light-transmitting wall member 6 is provided with a large number of curved surfaces 6a in the form of vertical lines (wavy in the horizontal direction) on its inner surface, and minute irregularities in the shape of frosted glass are provided on its outer surface. Because it has a lens effect, light is reflected, refracted, and further diffused, enhancing the visual effect.

(Effects of the invention) The present invention is as described above, and there is no need to look into the ignition hole from above or tilt the lighter to check the glow of the ignition glowing body, and there is no need for troublesome operations and it is safe. Of course, there is a window hole separate from the air intake hole, but red-hot conditions can be seen through a transparent wall member fitted in the same place by opening a window hole in the exterior case. This makes it easier to see and use. Furthermore, if the structure is configured as described in claim 2, the light emitted from the hood is reflected by the transparent wall member, refracted, and further diffused to enhance the visual effect, making it possible to more clearly confirm the red-hot state. It's effective.
