[Detailed description of the invention] (Field of industrial application) The present invention is a type of gas tank in which the ignition part protrudes forward by a predetermined length and has a shape convenient for igniting the combustor. This relates to a rod-shaped electronic gas lighter.

(Prior Art) This type of conventional rod-shaped electronic gas lighter was assembled by assembling a gas tank, piezoelectric mechanism, nozzle, lead wire, and gas pipe inside a rod-shaped case that was divided into two vertically.

(Problems to be Solved by the Invention) However, this structure in which all parts are assembled into a case that is vertically divided into two halves has the disadvantage that it is difficult to automate assembly.

An object of the present invention is to provide a rod-shaped electronic gas lighter whose assembly is easily automated.

(Means for Solving the Problems) The rod-shaped electronic gas lighter according to the present invention is formed by being divided into a gas tank part and an ignition mechanism part,
The gas tank portion includes a gas tank body that also serves as a gripping portion, a gas valve assembled to one end side of the gas tank body, and a joint portion provided on the gas tank body on the side from which the valve nozzle of the gas valve protrudes. , the ignition mechanism section includes a case vertically divided into two, a gas nozzle and ignition electrode section assembled at the tip inside the case, and an operating section assembled at the base side inside the case and protruding to the outside. a piezoelectric mechanism fitted to the outer periphery of the tip of the case; the other ignition electrode provided on the metal cylinder opposite to the gas nozzle/ignition electrode; Consisting of a lead wire that connects the mechanism part and both electrodes, a gas pipe that connects the gas nozzle/ignition electrode to a joint sleeve on the base side of the case within the case, and a joint provided at the base of the case. The gas tank portion and the ignition mechanism portion are connected by a mutual joint portion, and the joint sleeve of the ignition mechanism portion is jointed to the nozzle of the gas valve.

(Function) By making a rod-shaped electronic gas lighter by dividing it into the gas tank part and the ignition mechanism part in this way, at least the gas tank part can be automatically manufactured using already completed pocket gas lighter manufacturing equipment. . Furthermore, since the ignition mechanism section only requires assembly of electronic parts, assembly can be easily automated. Once both are assembled, they are completed by connecting them with joints.

The ignition mechanism section 2 includes a plastic case 14 that is vertically divided into two parts, and a gas nozzle/ignition electrode 15 is attached to the tip of the case 14 with the tip exposed. Electrode 15
A gas diffusion coil 16 is fitted to the tip of the tube. A piezoelectric mechanism 18 is assembled to the base inside the case 14, with the operating section 17 protruding outside the case 14.

The operating unit 17 has a gas lever operator 17 at its rear.
a, and is adapted to press the gas lever 7 when the ignition operation is received. A heat insulating ring 19 is fitted to the small diameter end portion 14a of the case 14, which also serves as a means for connecting the case 14. Further, a metal cylindrical body 20 is fitted on the outer periphery of the distal end side of the case 14, and the metal cylindrical body 20 protrudes forward from the case 14.
The other ignition electrode 21 is provided on the inner surface of the tip of the gas nozzle and ignition electrode 15 in a protruding manner, facing the gas nozzle/ignition electrode 15 .
Further, a ventilation hole 22 is provided in the metal cylinder 20 near the ignition electrode 21. The other end of the positive lead wire 23 connected to the positive electrode of the piezoelectric mechanism 18 is projected outside from the window 24 of the case 14 and is in contact with the metal cylinder 20. An earth lead wire 26 is connected to the earth cap 25 connected to the negative electrode of the piezoelectric mechanism 18, and the other end of the earth lead wire 26 is connected to the gas nozzle/ignition electrode 15. A gas pipe 2 is connected to the gas nozzle and ignition electrode 15.
One end of 7 is connected. A joint sleeve 28 is connected to the other end of the gas pipe 27. The joint sleeve 28 is positioned and supported by a sleeve receiver 29 that projects from the base side of the case 14. A joint portion 30 is provided at the base end of the case 14 and is inserted into the tank cover 11 to connect to the gas tank portion 1.

In such a rod-shaped electronic gas lighter, the gas tank section 1 and the ignition mechanism section 2 are automatically assembled on their respective production lines, and finally the protruding part of the piezoelectric mechanism 18 is inserted into the piezoelectric mechanism section storage recess 4A of the top cover 4. The joint part 30 of the ignition mechanism part 2 is connected to the joint part 1 provided on the tank cover 11 of the gas tank part 1.
Connect to 2. In this way, the mutual joint parts 12, 3
When interconnecting the gas valves 5 and 5 in the aligned state by zero-fitting, the valve nozzle 5a of the gas valve 5 is inserted into the hole 28a of the joint sleeve 28, and the gas supply system is also connected. At this time, the gasket 8 on the outer periphery of the valve nozzle 5a is attached to the joint sleeve 2.
The gas lever 8 is held between the end face of the gas lever 8 and the gas lever 7.

In the rod-shaped gas lighter assembled in this way, when the operating part 17 is pulled with a finger, the piezoelectric mechanism 18 undergoes sudden compressive strain and voltage is induced, and the ignition electrode 2
An arc flies between the gas nozzle and the ignition electrode 15. At the same time, when the operating part 17 is pulled, the gas lever 7 is pushed and rotated about the pivot point 9a, which causes the valve nozzle 5a to be pulled out and the gas valve 5 to open, and gas is ejected from the gas nozzle and ignition electrode 15. It is ignited by the arc mentioned above.

When gas leaks, press gas lever 7 to release gasket 8.
is pressed, the gasket 8 is compressed between the joint sleeve 28 and the gas lever 7, and gas leakage at the connecting portion is prevented.

In addition, in the ignition mechanism part 2, a joint part is provided on the inner surface of the base of the case 14, and in the gas tank part 1, the tank cover 11 is omitted, and the upper lid 4 and the tank container 3 are made into an integral structure, with the joint part protruding from the end surface. It is also possible to reverse the concavo-convex relationship of the joint.

The tank container can also be equipped with an injection valve.

(Effects of the invention) As explained above, the rod-shaped electronic gas lighter according to the invention is manufactured separately into the gas tank part and the ignition mechanism part, so the gas tank part uses the manufacturing equipment of already completed pocket gas lighters. In addition, since the ignition mechanism requires only the assembly of electronic parts, the assembly can be easily automated.

Further, with such a structure, replacement and repair in the event of failure and tank replacement when the gas tank portion is disposable can be easily performed.
