Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a delayed operation type high voltage generator that accumulates impact force and uses another means to release the impactor pin and create an impact. Mainly used for lighting cigarette lighters, etc.

Structure of conventional example and its problems In Fig. 3, 1 is a main body case of a high voltage generator housing a piezoelectric element, 3 is an impactor pin, 5 is a cam for engaging the impactor pin, 5a is an engaging portion, 7 is the operator, 7
a is the inclined side of the operator 7. When the operator 7 is pressed in the direction of the arrow, the impactor pin 3 slides to the engagement portion 5a while contacting the inclined side 7a and the lower side of the impactor pin engagement cam 5. When pressed further, the impactor pin 3 moves to the upper end of the engaging portion 5a. Figure 3 shows a state in which the impactor pin 3 is further pressed by A'. Since the pin 3 and the operator 7 are continuously engaged, the impactor pin 3 is also pressed following the operator 7, and the impact spring biased against the impactor is further deflected, increasing the operating load. The impact spring had a poor operating feel, and the design of the impact spring meant that the contact dimensions were small, making it impossible to use a spring with strong elasticity.

Purpose of the invention: To provide a delayed operation type high lightning pressure generator that reduces the operating load of an operator used to apply an impact to a piezoelectric element, provides a good operating feel, and has a margin for operating amount.

Structure of the invention In a delayed operation type high voltage generator that accumulates impact force and uses another means to release the impactor pin for impact, an impactor pin is provided in a notch for engaging the impactor pin of the operator. An operator having a U-shaped groove on the upper side following the sliding slope side is used to ensure a sufficient amount of operation.

DESCRIPTION OF EMBODIMENTS In FIGS. 1 and 2, 1 is a main body case of a high voltage generator housing a piezoelectric element, 2 is an impactor, 3 is an impactor pin, 4 is an impact spring, and 5 is an impactor pin 3. , 5a is an engaging portion, 6 is an operating element, 6a is an inclined side provided on the operating element 6, and 6b is a U-shaped notch provided continuously on the upper side of the inclined side 6a.

In FIG. 1, when the operator 6 is pressed in the X direction, the impactor pin 3 slides while contacting the inclined side 6a of the operator 6 and the lower side of the engagement cam 5, It is pushed up by the inclined side 6a so as to engage with the engaging portion 5a of 5, and engages with the engaging cam 5 as shown in FIG. At this time, the impactor pin 3 falls from the inclined side 6a of the operating element 6 into the U-shaped groove 6b, and is no longer engaged with the operating element 6 and engaged only with the engaging portion 5a. In this case, even if the operator 6 is further pressed by an arbitrary margin operation amount A, it will be pressed by the operator 6 alone, so the structure is such that the biasing force of the impact spring 4 is not applied when pressing dimension A. The operating feel is good, and the impact spring 4 is not pressed more than necessary, which reduces the burden.

Effects of the invention By increasing the operating margin of the operating element used to apply shock to the piezoelectric element, the operating load is reduced,
We were able to provide a high-voltage generator that has a good operating feel and has a margin for operating the operator even when designing a lighter.
