Description

[Detailed description of the invention] The present invention relates to a high voltage generator.

In conventional impact type high voltage generators, a hammer (impacting member) having a pin is twisted, the pin is locked in a through hole in the side wall of the frame, and the locking is performed by a movable member having an inclined part. There was one that was designed to unravel and strike a piezoelectric element.

However, this conventional piezoelectric device has a hammer (
Since torsion is applied to the impact member (impact member), processing of the impact spring, hammer (impact member), etc. is complicated, and assembly work efficiency is poor.

In addition, since the through holes in the frame body and the inclined parts of the movable members were exposed to the outside, when these high voltage generators were incorporated into lighters, etc., dirt could enter through the through holes, making operation difficult. There was a drawback that it could happen.

In order to improve the shortcomings of the high voltage generator of the conventional structure as described above, the present invention stores and fixes a substantially U-shaped linear spring inside the frame, making it easy to assemble, preventing the intrusion of dust, etc., and providing long-term use. The present invention provides a high-performance high-voltage generator that can withstand use.

Hereinafter, one embodiment of the high voltage generator of the present invention will be described with reference to the drawings.

In the figure, 1 is a piezoelectric element, 2 is a stopper, 3 is a receiving screw,
4 is an intermediate terminal interposed between the two piezoelectric elements 1; 5 is a high voltage lead wire; 6 is a striking member having a groove 6a and a through hole 6b;
Reference numeral 7 denotes a striking spring; 8, a movable member that houses the striking member 6, the striking spring 7, etc.; and has two inclined parts 8a and a locking part 8b; 9, fitted into the through hole 6b; A pin 10 is a pin for slidably locking the striking member 6 in the movable member 8 by being locked with the locking portion 8b at the time of return; 10 is the piezoelectric element 1, the return spring 11, the movable member 8, etc. A frame body made of synthetic resin and having a stepped portion 10a, 12 is the stepped portion 10a.
A substantially U-shaped linear spring 13 is engaged with the groove 6a of the striking member 6 before operation. Reference numeral 13 indicates a fixing member for fixing the linear spring 12.

This fixing member 13 is fixed to the frame body 10 by welding by ultrasonic waves, heat, etc., press-fitting, or press-fitting by undercuts, nails, etc.
is fixed to the inner periphery of the opening.

Next, the functions and effects of the present invention will be explained.

When the movable member 8 is pushed in the direction A (FIG. 1), the striking member 6 is engaged by the substantially U-shaped linear spring 12 as shown in FIG. 3, and remains stationary, with only the striking spring 7 is compressed.

During this time, the pin 9 separates from the locking portion 8b of the movable member 8, but is guided by the inner wall of the frame 10 and does not come off.

Then, as the movable member 8 is pushed in the direction A, the end portion 12a of the linear spring 12 moves toward the two inclined portions 8a of the movable member 8.
It is pushed out and spread out as shown in Fig. 4.

At this time, the impact member 6 impacts the pad 2 and the piezoelectric element 1 by the stored impact spring 7, and a high voltage is generated.

Thereafter, the movable member 8 is pushed back by the return spring 11, and at the same time, the pin 9 is locked to the locking portion 8b of the movable member 8, so that the striking member 6 that is slidably housed in the movable member 8 is also When the movable member 8 is pushed back and returns to the position before the operation, the substantially U-shaped linear spring 12 fits again into the groove 6a of the striking member 6, and one operation is completed.

As described above, this high voltage generator does not require twisting of the striking member, so processing of the striking spring, striking member, etc. is easy, and the assembly work is highly efficient. A high voltage can be easily extracted from the element unit which has a pin and allows the striking member to return at the same time as the movable member while being fixed.

In addition, the frame body and movable members do not have any through holes that are exposed to the outside, so there is no intrusion of dirt, etc., and it can be operated smoothly over a long period of time, exhibiting extremely excellent performance in terms of durability. It has high practical value.
