Description

[Detailed explanation of the invention] This invention discharges the electric charge of a capacitor charged by a power supply battery through a transformer by switching a switch, causing a high voltage current induced in the secondary winding to be spark-discharged above the nozzle. , in a discharge ignition type lighter configured to ignite fuel gas ejected from a nozzle, relates to a device for attaching an operation button for operating the switch and opening the nozzle so as to be movable up and down along the lighter casing, particularly when the operation button is attached to the lighter. It is mounted so that it hardly protrudes from the outside surface and is located almost on the same plane as the outside surface of the lighter casing, giving the lighter a nice appearance and preventing the operation button from colliding with other objects and operating against the user's intention. The attachment of the operating button to prevent the user from being exposed to the user's finger and to ensure safety in use relates to the device, and will be described in detail below with reference to the drawings.

In the figure, 1 is a lighter casing that holds a fuel tank 2, battery 3, electric component unit 4, etc. inside, and has a flame outlet 5 on the top surface and an operation button operation port 6 on one side. It is formed.

The open bottom surface of the lighter casing 1 is closed with a bottom lid 7.

The electrical component unit 4 connects a capacitor 8, a switch 9, a transformer 10, etc. to a synthetic resin frame member fixedly held on the upper surface of the tank 2 through predetermined wiring to form a circuit that generates discharge sparks. It is incorporated into the lighter casing 1 as a unit member assembled into the lighter casing 1.

Reference numeral 11 denotes a nozzle of a burner valve that is attached to the upper side of the fuel tank 2 and communicates with the inside of the tank.
It extends upward from the top surface.

The upper end of the nozzle 11 is located below the flame outlet 5, and the discharge electrodes 4a are attached to the unit 4 so as to face each other.

12 is an operating cam member inserted into the nozzle 11,
The upper surface of the cam member 12 collides with the collar 11a of the nozzle 11.
When the fuel gas rises, the nozzle 11 is raised together to open the burner valve and allow the fuel gas to be ejected.
When the cam member 12 is brought into contact with the switch a and the cam member 12 is raised, the switch button 9a is pressed to switch the contact point of the switch 9.

At this time, the charge stored in the capacitor 8 is discharged through the primary winding of the transformer 10, and the high voltage current induced in the secondary winding causes a spark discharge between the discharge pole 4a and the upper end of the nozzle 11. I am forced to do it.

The operating cam member 12 is always biased in a downward direction by the tension of a spring tensioned on the nozzle 11.

Reference numeral 13 denotes an operation button, which is positioned within the button operation opening 6 and fixed to the operation cam member 12 by engagement of a dowel and a dowel hole and by a mounting screw 14.

As shown in FIG. 1, the mounting screw 14 is attached to a position where it is covered by the lighter casing 1 when the burner nozzle 11 is closed and exposed within the button operation port 6 when the burner nozzle 11 is opened.

Due to the position of the mounting screw 14, the mounting screw 1 can be removed when not in use.
Since the button 4 is hidden inside the lighter casing 1 and is not exposed to the outside, it has a good appearance and can be easily removed from the operation port by lifting the operation button 3 upward as described later.

The operation button 13 is a substantially plate-shaped member, and includes a closing plate portion 13a located on the inner surface of the lighter casing 1 and formed slightly larger than the button operation port 6 to close the operation port 6 from the inner surface of the casing 1; An operating section 13b that is located within the operating port 6 and has a notch that allows vertical movement operation with a finger.
It becomes one by integrating.

The operation button 13 is formed to be approximately the same width or slightly narrower than the button operation opening 6, and can be inserted into the lighter casing 1 from the outside.

The operation part 13b has an operating distance a from the height of the button operation port 6.
It is formed as short as possible, and can be moved upward to operate the lift switch changeover button 9a of the nozzle 11.

When the operation button 13 is lifted by the gap 9, the screw 14
is exposed from the button operation opening 6, so that the screw 14 can be attached or removed, and by removing the screw 14, the operation button 13 can be removed from the operation cam member 12 and pulled out from the button operation opening 6.

When the operation button 13 is removed in this manner, the fuel tank 2, battery 3, and electrical component unit 4 inserted and held in the lighter casing 1 can be pulled out together with the bottom cover 7 downward.

The operation button 13 is a plate-shaped member, and the operation part 13b is located inside the button operation opening 6 of the lighter casing 1, so that the operation button 13 and the outer surface of the lighter casing 1 are flush with each other. I can do it.

Thus, according to this invention, the battery 3, the capacitor 8, the switch 9, the transformer 10 are included, and the switch 9
A discharge gap is formed between the discharge pole 4a and the burner nozzle 11 to cause a spark discharge of the high voltage current generated by the switching of In this discharge ignition type lighter, the operating cam member 12 can be freely operated from outside the lighter casing 1, and the lighter casing 1 is provided with a button operating port 6 that extends along the opening/closing direction of the burner nozzle 11. A closing plate part 13a that closes the button operation opening 6 and slides along the inner surface of the lighter casing 1, and an operation part 13b that is located inside the button operation opening 6 and slides while being guided by the button operation opening 6. An integral operation button 13 is fixed to the operation cam member 12 with a mounting screw 14, and is attached to the burner nozzle 1.
At least the burner nozzle 11 and the switch 9 are located between the operating portion 13b and the button operating port 6 in the valve opening direction of 1.
A gap corresponding to the working distance a is formed to operate the button operation port 6, which is covered by the lighter casing 1 when the burner nozzle 11 is closed, and is covered by the button operation port 6 when the burner nozzle 11 is opened.
While arranging the mounting screw 14 at a position exposed to the inside,
Since the outer surface of the operating portion 3b is formed between the outer surface of the lighter casing 1 and the road surface, the operating button 13 does not protrude outward from the outer surface of the lighter casing 1, and the operating button 13 does not collide with other objects. This eliminates the danger of the lighter being ignited due to being operated against the user's intention, making it possible to provide an extremely safe lighter.
Such safety makes it possible to provide an extremely superior operating button mounting device for a battery-discharge type lighter that ignites with just one operation of the operating button, as well as an operating button mounting device that moves the operating button up and down along the lighter casing. Since they are distantly related, the interlocking mechanism between the operation button 13, the switch 9 and the nozzle 11 can have a very simple structure, making it possible to provide an optimal structure for a pocket lighter.

Furthermore, since the mounting screws 14 are arranged at positions that are covered by the lighter casing 1 when the burner nozzle 11 is closed and exposed in the button operation port 6 when the burner nozzle 11 is opened, the mounting screws 14 can be removed when the lighter is not in use. Since it is hidden inside the lighter casing 1 and is not exposed to the outside, it has a good appearance and can increase the product value. In addition, by lifting the operation button 3 upward, the operation port 6 can be removed.
Since the mounting screw 14 can be easily removed from the
The operation button 6 can be easily attached and detached, and the lighter can be easily assembled.
