Abstract

A disposable lighter with safety ignition unit is comprised of a body and a head, wherein a nozzle, a ring, a wind mask, a lever press plate, a spring, a flint, a bracket and an igniting wheel set with safety ignition unit are arranged on said head. The igniting wheel set with safety ignition unit includes two central axles, two cinctures and an ignition wheel which is used to make friction with said flint so as to generate sparks, said two cinctures are located on each end of said igniting wheel, the inner diameter(s) of said cincture is slightly larger than the outer diameter of the portions of the igniting wheel set which they encircle, so as to form the rotation of the cinctures as “sliding wheels.” The two central axles are supported on the bracket of the outer head and act as common rotational axle of said cinctures and igniting wheel. Characterized by its reasonably structured design and low cost, the present disposable lighter can effectively avoid dangers caused by ignition of lighter by a child or errors in operation.

Description

[0001] This application claims priority of, and is a continuation-in-part of, PCT International Application, PCT / CN2006 / 00134, filed Jan. 24, 2006, which application is incorporated herein by this reference.FIELD OF INVENTION

[0002] The present invention relates to a disposable lighter with a safety ignition unit that makes the operation of an unintended user more difficult, more particularly an ignition unit preventing children from igniting the disposable lighter unnecessarily.BACKGROUND

[0003] Presently, most lighters available in the market, especially disposable lighters, can be easily ignited by young children and thus cause hidden dangers in property loss and personal injury. More and more countries, especially Western countries, have attached great importance to the protection of children and imposed strict measures on safety requirements for lighters. Nowadays, both the U.S. government and U.S. Consumer Product Safety Commission demand a safety device in every cigarette lighter,...
