Description

[Detailed Description of the Invention] The present invention relates to a gas lighter, and particularly to a gas lighter that incorporates a light emitting element and a light receiving element and generates a high voltage using an optical signal to ignite the gas lighter.

Conventionally, when forming a recess in the lighter body, the recess 1 is also molded integrally with the lighter body 2 as shown in FIG. 1, which complicates the molding process and increases manufacturing costs. It is a protrusion within the main body and becomes an obstacle, making it difficult to assemble smoothly.

Therefore, in view of the above-mentioned drawbacks, the present invention was devised in order to solve this problem.The purpose of the present invention is to provide a gas lighter in which a concave portion can be easily provided and which does not become an obstacle to assembly. In a gas lighter, a recess is formed at an appropriate location in the main body of the lighter, a light emitting element is provided on one side of the recess, and a light receiving element is provided on the other side facing the light emitting element, and the recess has a removable cross section. The gas lighter is characterized in that a substantially U-shaped elastic protective cover is fitted into the lighter body, and a conductive part for a protective cover removal jig that reaches the protective cover from its lower end is formed in the lighter body.

Next, an example of implementation of the present invention will be described with reference to the drawings.

In the figure, 10 is a lighter body, and this lighter body 10
Recesses 11 are formed at appropriate locations, and the recesses 11 have an interval at least wider than the diameter of the tobacco.

The recess 11 is provided with an LED 12 as a light emitting element on its lower surface, and a phototransistor 13 as a light receiving element is provided on its upper surface facing the LED 12.

A protective cover 14 for the front 3ED 12 and the phototransistor 13 is fitted into this recess 11 .

The protective cover 14 is made of a transparent, elastic synthetic resin material and has a substantially U-shaped cross section, and a recessed step 15 is formed at its periphery.
It is fitted into the recess 11 and fixed.

This protective cover 14 is formed to be wider than the recess 11 of the lighter body 10, and when pushed into the recess 11, it is securely fixed by its elasticity.

Further, the outer surface of this cover 14 is coated with a paint 17 for blocking light rays.
is pasted thereon, and light beam passing portions are formed on the upper and lower pieces of the cover 14 without pasting the paint 17 thereon.

A condensing lens 18 is integrally formed in the light passing portion of the lower piece of the cover 14 in correspondence with the LED 12.
In addition, the light beam passing section of the upper piece has a concave hole 20 in which a rubber ring body 19 is fitted, and the pores of this ring body 19 are parallel to each other. A ray of light passes through.

This ring body 19 is formed to slightly protrude from the outer surface of the cover 14, and is pressed into contact with and communicates with the through hole 22 of the support base frame 21 provided in contact with the outer surface of the cover 14.

This conductive hole 22 is located under the phototransistor 13, and the phototransistor 13 has directionality due to these long pores, and only the light from the LED reaches there, and no external light enters, thereby preventing malfunction. .

On the other hand, a gas tank 23 is built in below the recess 11.
A concave groove-shaped conductive portion 24 is formed on the outer surface of the gas tank 23, into which a thin rod of a protective cover removal jig is inserted from the lower end of the lighter body 10.

Although the above-mentioned embodiment shows the case where the cover 14 is provided with a condensing lens, in the case of a type in which the condensing lens is integrally provided with the LED 12, the cover does not include the condensing lens. Of course, it is possible.

The present invention is constructed as described above, and when it is installed, the protective cover 14 is pushed into the recess 11 of the lighter body 10 and fitted.

To remove it, remove the bottom cover, insert the thin rod 25 of the jig into the conductive part 24, and use the tip of the thin rod to push up the lower piece of the cover 14 to disengage the recessed step 15 and remove it. It is something.

The present invention is constructed as described above, and includes a removable elastic protective cover having a generally U-shaped cross section that is fitted into the recess, and a conductive portion for the protective cover removal jig that reaches the protective cover from its lower end within the main body of the lighter. , the lighter body can be easily molded, manufacturing costs can be reduced, and the assembly process can be performed efficiently.

Furthermore, since the conductive portion is formed, the cover can be easily removed.

As described above, the present invention has excellent advantages, and implementing the present invention has great practical value.
