Abstract

PURPOSE:To contrive to improve the safety in use by a constitution wherein an ignition lever is hindered to be pressed when the gas lighter is out of use, while the ignition lever is put away from an ignition nozzle when in use. CONSTITUTION:When the gas lighter is not intended to use or is under the state that an ignition lever 11 and a guide arm 10 are housed in a lighter main body 1, the ignition lever 11 can not be pressed down because both the edge parts of a notch 1b hinders the pressing movement of a finger tip. When the gas lighter is intended to use or is under the state that the ignition lever 11 and the guide arm 10 are drawn outwards laterally and the ignition lever 11 is pressed down, the end opposite to a fork part 4a of a valve opening lever 4 is pressed down through a projecting arm 11e, resulting in raising the fork part 4a, the rising motion of which causes to pull up an ignition nozzle 3 so as to open a valve in order to jet fuel gas. Simultaneously with this, the pressing part 6a of a piezoelectric unit 6 is pressed down through a projection 11d, resulting in striking an piezoelectric element therein so as to generate high tension current and to discharge it in order to ignite fuel gas jetting from the tip of the ignition nozzle 3. In this case, because the lever 11 is away from the nozzle 3, the safety is ensured.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas lighter, particularly a portable pressure ignition type gas lighter.

Conventional gas lighters of this type often have an ignition lever or an exposed part on the outside of the lighter body, and because the ignition lever can be ignited simply by pressing the ignition lever, it is difficult to ignite small objects inside the cell phone. There were cases where the φ was ignited due to contact. In addition, because the distance between the ignition lever and the ignition nozzle was short, if the ignition state continued for several seconds, the heat of the flame would reach your fingers and easily cause burns. Therefore, there was a problem with safety.

In view of the above-mentioned problems, the present invention aims to provide a highly safe gas lighter.

In the gas lighter according to the present invention, the ignition lever is housed in the lighter body together with the guide that guides the ignition lever, and can be pulled out in a direction away from the ignition nozzle, so that the ignition lever can be easily pushed when not in use. In addition, the ignition lever is moved away from the ignition nozzle during use.

Detailed explanation of the present invention based on an embodiment shown in the following 11 figures: 1.1; A lighter body made of synthetic resin with a notch 1b formed therein;
Reference numeral 3 indicates an ignition nozzle with a valve located directly below the grilling outlet 1a and connected to the fuel oil tank 2, and which opens when it is pulled up; 4, a fork portion 4a provided at one end is the ignition nozzle 3; a valve-opening lever 6 having a dogleg-shaped cross section and having a center portion supported on the ribs 5 and acting to pull up the ignition nozzle 3 by pushing down the other end using the center portion as a fulcrum; is a suppressing portion 6 which is disposed directly below the notch 1b and is given an upward movement habit by a spring or the like.
7 is a piezoelectric unit in which one end is connected to the piezoelectric element in the piezoelectric unit 6, and the other end is connected to the piezoelectric element in the piezoelectric unit 6. Four high-voltage wires, 9, held on the ribs 8 with their ends located near the ignition nozzle 3, are provided closely to the outer surface of the piezoelectric unit 6.
0 is the bottom of the piezoelectric unit 6 (flll + the base clamped and fixed between the step part 6b and the lighter body 1), Oa and the upright part connected to the base 10a via the hinge part iob and having the guide groove 10c. 10d and the upright part], and a locking pawl 1oe protruding inward from Od, and the upright part 10d is capable of swinging in a vertical plane, and the upright part 10d
A synthetic resin guide arm (see FIG. 2) whose locking claw 10e engages with the partition wall 9 when the ignition nozzle 3 is swung to the right in FIG. 1 in the direction P1 away from the ignition nozzle 3. ) 111-1 Consists of a base portion 11a vertically slidably guided in a guide groove 10c and a head portion 11b fitted into a notch 1b so as to be freely removable in the lateral direction.

A finger rest portion 11c is provided on the second surface of the head 1'lb, and a projection l that can come into contact with the pressing portion 6a of the piezoelectric unit 6 is provided on the lower surface.
This is an ignition lever made of synthetic resin and provided with protrusions lie that abut the id and the other end of the valve opening lever 4, respectively.

Since the gas lighter according to the present invention is constructed as described above, the ignition lever 11 and the guide arm 1o are stored in the lighter body 1 as shown in FIG. 1 for carrying when not in use. When the head 11b of the ignition lever 11 is inserted into the notch 1b, the ignition lever 11 cannot be pushed down because both edges of the notch 1b get in the way of the fingertips trying to press it. Therefore, when not in use, the ignition lever 1 cannot be easily pushed down, so it is safe and will not accidentally ignite due to contact with other objects.

Next, for use, put your finger on the ignition lever 11 and the guide arm l as shown in FIG.
When the upright portion 10d of O is pulled out to the right, that is, swung, the oscillation is stopped when the locking pawl 10e engages with the partition wall 9. In this state, both edges of the notch 1b are out of the way, so the ignition lever 11 can be pushed down. Therefore, as shown in FIG. 3, the ignition lever 11
When pushed down, the other end (right end) of the valve opening lever 4 is pushed down via the protrusion 11e, and the fork portion 4a rises.
As a result, the ignition nozzle 3 is pulled up and opened, and combustion gas is ejected from the tip of the ignition nozzle 3.

At the same time, the protrusion 11. piezoelectric unit 6 via d
As the pressing part 6b is pressed down and the piezoelectric element inside is struck, a high-voltage current is generated, which is discharged through the high-voltage conductor 7 from the other end toward the ignition nozzle 3, and is ejected from the tip of the ignition nozzle 3. Ignite the fuel gas. in this case,
Since the ignition lever 11 is separated from the ignition nozzle 3, even if the ignition state continues for several seconds, the heat of the flame does not reach your fingers, making it difficult to burn your fingers.
It's safe.

As mentioned above, the gas lighter according to the present invention has the important practical advantage of being extremely safe.
