Piezoelectric ignition mechanism of child-resistant lighter

Abstract

A piezoelectric ignition mechanism of a child-resistant lighter that suitable to any piezoelectric lighter is provided, which includes an energy accumulating conduct tube and a core element. A plexor preferably includes an impact shaft disposed in the energy accumulating conduct tube that 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 located on the core element, which is 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.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to ignition mechanism of lighter. More specifically, to structures involving a piezoelectric ignition mechanism that prevents inadvertent operation by children. [0003] 2. Description of the Related Art [0004] 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. SUMMARY OF THE INVENTION [0005] 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 over...

Benefits of technology

[0012] 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:

[0013] 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.

[0014] 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.

[0015] 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.

Problems solved by technology

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.
