Description
- 1. Field of the Invention
- The present invention relates to ignition mechanism of lighter. More specifically, to structures involving a piezoelectric ignition mechanism that prevents inadvertent operation by children.
- 2. Description of the Related Art
- Conventional lighter provided a direct ignition mechanism that will be easily inadvertent operated by children. Thereby, misfortunes such as fire or injurer may occur. Some lighter makers added various safety latch lock on the lighter that increases product cost and inconvenience for user's operation. Some makers increase the pressing force of ignition mechanism to 9.5 to 10 pound so as to keep the CR law of some countries that makes activation of the lighter more difficult.
- The primary object of the present invention is by providing a piezoelectric ignition mechanism of a child-resistant lighter with increased safety and low fabrication cost to overcome the deficiencies mentioned above.
- In accordance with the primary object of the present invention, an improved structure of a piezoelectric ignition mechanism of child-resistant lighter is provided, wherein it includes an energy accumulating conduct tube and a core element. A plexor preferably including an impact shaft is positioned in the energy accumulating conduct tube, which has roundness shape. A guiding shaft mounts on the energy accumulating conduct tube. A guiding slot assembly that controls the movement of the energy accumulating conduct tube is located on the core element, which is associated with the energy accumulating conduct tube. The guiding slot assembly further includes a pair of circular control guiding slots and a pair of ignition guiding slots. The energy accumulating conduct tube is positioned in the guiding slot assembly. The guiding shaft and the impact shaft of the energy accumulating conduct tube are positioned respectively in the control guiding slots and in the ignition slots.
- The circular control guiding slot includes an arc guiding slot and 3 segments of straight guiding slots, and one of the straight guiding slots having a slope shape is positioned on the top of the circular guiding slot. The circular control guiding slot has a “fan” shape, and the ignition guiding slot has an inverse L-shape.
- The present invention comprises an energy accumulating conduct tube and a core element. A plexor preferably including an impact shaft disposed in the energy accumulating conduct tube. The energy accumulating conduct tube is roundness. A guiding shaft is positioned on the energy accumulating conduct tube. A guiding slot assembly that controls the movement of the energy accumulating conduct tube is positioned on the core element that associated with the energy accumulating conduct tube. The guiding slot assembly further has a pair of circular control guiding slots and a pair of ignition guiding slots. The energy accumulating conduct tube is positioned in the guiding slot assembly. The guiding shaft and the impact shaft of the energy accumulating conduct tube are positioned respectively in the control guiding slots and in the ignition slots.
- When the lighter in an activated configuration:
- The first step, as pressing the energy accumulating conduct tube for the first time, the guiding shaft moves down along one side of the control guiding slot, that is, the arc guiding slot and rotates itself, in the meantime the impact shaft cannot make the energy accumulating spring produce deposit energy.
- The second step, weakening the force pressed on the energy accumulating conduct tube, due to the upward action of the returning spring, the guiding shaft and an energy release limit window drive the impact shaft moving up vertically together, and the impact shaft slides along the bottom bevel edge of the energy release limit window and stops on the energy accumulating block when it moves up on the half way.
- The third step, immediately following the second step, pressing the energy accumulating conduct tube for the second time, the guiding shaft then moves down vertically while the impact shaft remains on the energy accumulating block and causes energy depositing on the energy accumulating spring. Continue pressing the energy accumulating conduct tube, the guiding shaft may be driven down to the bottom, then the upper bevel edge of the energy release limit window forces the impact shaft sliding away from the energy accumulating block and the energy accumulating spring releases instantly, so cause the plexor impacts the strike peg with heavy force to produce high voltage spark. Due to children's simplicity activity, he may loose hold of his hand after the first pressing on the energy accumulating conduct tube and during the resetting process of the energy accumulating conduct tube, he will not press the tube again for depositing energy on the energy accumulating conduct tube. Therefore, the lighter will be driven back by returning
spring 11 directly to the deactivated configuration, that is the configuration before the operation. Thus prevented inadvertent operation by children. Compare to prior designs, the advantageous effects of the present invention are as followings: - 1. It is versatility that the present invention shares the same operation way, same configuration and same dimension with conventional piezoelectric ignition element, and can be used in any of prior designs of lighter.
- 2. It is convenience for production and management because the present invention shares the same cost and same production arts and crafts with the piezoelectric lighter without safety measures.
- 3. It is safe and economical that the present invention resolves the problem of inadvertent operation by children without adding any additional safety latch or lock.
- Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

FIGS. 1-7 , wherein comprising: - 1. energy accumulating conduct tube; 2.guiding slot assembly; 3.core element; 5. energy accumulating spring; 6. guiding shaft; 7. impact shaft; 8. plexor; 9. circular control guiding slot; 10. ignition guiding slot; 11. returning spring; 12. strike peg; 13. conduct sheet copper; 14. piezoelectric ceramic; 15. energy release limit window; 16. discharge sheet copper; 17. copper cap; 18. discharge wire; 19. energy accumulating block; 20. elasticity relaxing triangle section; 21. slide bevel edge; 22. stop returning guiding arc edge; 23. gas control block.
- The preferred embodiment:
- As shown in
FIG. 1 toFIG. 7 , a piezoelectric ignition mechanism of a child-resistant lighter comprising: energy accumulatingconduct tube 1;gas control block 23; guidingslot assembly 2;core element 3;energy accumulating spring 5; energyrelease limit window 15; guidingshaft 6;impact shaft 7;plexor 8; circularcontrol guiding slot 9;ignition guiding slot 10;energy accumulating block 19; elasticity relaxingtriangle section 20;slide bevel edge 21; stop returning guidingarc edge 22; returningspring 11;strike peg 12;conduct sheet copper 13; piezoelectric ceramic 14;discharge sheet copper 16;copper cap 17 anddischarge wire 18. Thereinto,control guiding slot 9 which is positioned in guidingslot assembly 2 guides the travel distance of guidingshaft 6 and consequently drives energyrelease limit window 15 moving, thereby fulfils the activating process ofimpact shaft 7 amongenergy accumulating block 19 andignition guiding slot 10. - Referring to
FIG. 3 toFIG. 7 , where solid and fine lines illustrate the spread inner circle structure of guidingslot assembly 2; dotted lines illustrate the energyrelease limit window 15; and a large and a small circle refer to guidingshaft 6 andimpact shaft 7 respectively. - When the lighter in an activated configuration:
- The first step, as pressing energy accumulating
conduct tube 1 for the first time, guidingshaft 6 will move down along one side ofcontrol guiding slot 9 as indicated inFIG. 3 toFIG. 4 , and theimpact shaft 7 and energyrelease limit window 15 move down together with it, in themeantime impact shaft 7 cannot makeenergy accumulating spring 5 produce deposit energy. The second step, weakening the force pressed on energy accumulatingconduct tube 1, due to the upward action of returningspring 11 and the guiding function of stop returning guidingarc edge 22, guidingshaft 6 and energyrelease limit window 15drive impact shaft 7 moving upward together; then impactshaft 7 slides along the bottom bevel edge of energyrelease limit window 15 and stops onenergy accumulating block 19 when it moves up at the place as indicated inFIG. 5 . - The third step, immediately following the second step, pressing energy accumulating conduct tube I for the second time, guiding
shaft 6 then moves down vertically to the place as indicated inFIG. 6 , whileimpact shaft 7 remains onenergy accumulating block 19 causing energy depositing onenergy accumulating spring 5. Continue pressing energy accumulatingconduct tube 1 downward, guidingshaft 6 may be driven down to the bottom as indicated inFIG. 7 , then the upper bevel edge of energyrelease limit window 15 forces impactshaft 7 sliding away fromenergy accumulating block 19 as shown with dotted arrowhead inFIG. 6 , whileenergy accumulating spring 5 releases instantly, so causeplexor 8 impact thestrike peg 12 with heavy force to produce high voltage spark. The releasing of the pressure adding on energy accumulatingconduct tube 1 will deactivate ignition, and the lighter will return to the configuration before activating by returningspring 11. - When a child operates the lighter inadvertently, as he presses energy accumulating
conduct tube 1, due to children's simplicity activity, he may loose hold of his hand on thetube 1 when guidingshaft 6 moves down to the place as indicated inFIG. 4 . Thus the lighter passes through the configurations ofFIG. 3 toFIG. 4 , in the middle of which passed throughFIG. 5 , when the child cannot press energy accumulatingconduct tube 1 quickly enough for the second time. As a result the lighter is driven back by returningspring 11 directly to the deactivated configuration as indicated inFIG. 3 (the configuration before the operation). Thus prevented inadvertent operation by children. - It should be emphasized that circular
control guiding slot 9 in the present invention is formed with an arc guiding slot and 3 segments of straight guiding slots, and one of the straight guiding slots having a slope shape is positioned on the top of the circular guiding slot. The circular control guiding slot has a shape close to a “fan”. - In addition,
ignition guiding slot 10 of the present invention may have a inversed L-shape; and elasticity relaxingtriangle section 20 which is belowignition guiding slot 10 andslide bevel edge 21 will be able to form a shape near Γ withignition guiding slot 10; and as shown inFIG. 7 , when said circularcontrol guiding slot 9 has a fan shape, said stop returning guidingarc edge 22 may be has a shape of inversed water drip. - The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
- It is versatility that the present invention shares the same operation way, same configuration and same dimension with the conventional piezoelectric ignition element and can be used in any of prior designs of lighters. It is safe and economical of the present invention, and resolves the problem of inadvertent operation by children without adding any safety latch or lock. It is also suitable for Industry production.
