The electronic lighter of said structure, no matter adult or children, all can use this lighter easily, but for prevent children especially young child cause burning because of the lighter improper use or the generation of fire incident, the many countries such as the U.S., Canada, Australia and each state of Europe have stipulated that all the lighter of selling in its market all must be provided with release mechanism, to prevent the generation of similar accident.The electronic lighter that development has release mechanism has become the manufacturing main target of lighter.

Summary of the invention

The purpose of this utility model provides a kind of not only safe in utilization but also easy to operate electronic lighter with new type of safe mechanism.

The utility model is realized in the following way: the safe electronic lighter, mainly comprise body, igniter and air-valve device, and body comprises oil tank, fuel tank bottom, hurricane globe and emergency support; Igniter comprises button, engine firewall, lead, metal seesaw, interior cover, overcoat and piezoelectric crystal component; Air-valve device comprises valve component, drainage core assembly, flame adjusting ring, unlatching element and air-out needle, and wherein button is made up of safety button and button ignition switch respectively in the igniter; Position at inner corresponding safety button of the oil tank of body and button ignition switch is respectively equipped with the limiting block wall; Distance between safety button lower end surface and its limiting block wall is less than the igniting stroke of igniter.

Because the utility model has utilized the characteristic of piezoelectric ignition system device: during igniting, the button of igniter must be depressed into the igniting stroke from top to bottom, the just energy abrupt release that igniter is stored in compression process, the impact of piezo-electric crystal generation relatively, causing the high voltage electric energy that is stored in the piezo-electric crystal discharges, by conductor circuit the fire on the air-valve device is chewed the pipe gas outlet and cause high-voltage spark, lighter is lighted.The distance that presses down as operating parts does not reach the igniting stroke, and the impact spring of igniter just can not produce impact at the energy that this section compression process is stored, and makes button return to the elastic force of origin-location and only can become.Owing in the utility model, be provided with above-mentioned release mechanism, during igniting, with the igniter button down, button ignition switch just can relative fuel tank with safety button to lower slider.When pressing down distance when reaching, near but when not reaching the igniting stroke, the end face of safety button bottom just contacts with limiting block wall in the oil tank, produces a suitable resistance, the prevention safety button continues to move downward.This moment, igniter also can not excite high-voltage spark that lighter is lighted.Have only and continue consciously at this moment to apply bigger pressure (because its active area is little to button ignition switch, then its active force just strengthens), just can continue to press down and reach igniter and excite the required igniting stroke of high-voltage spark, the some gas valve has discharged fuel gas.Therefore children when especially young child is plaied with fire, press down when being subjected to resistance at safety switch, or because of not continuing consciously firmly button ignition switch to be depressed, or, all lighter can't be lighted usually, thereby guarantee the security performance of lighter because of there not being enough strength.
