ABSTRACT:
Disclosed is a piezoelectric type lighter for use in lighting pipes comprising a fuel storage having a fuel in let valve fixed at its ceiling, a piezoelectric unit, a thumb-pusher fixed to the piezoelectric unit, an operating lever operatively connected to the flame valve and to the thumb-pusher for opening the flame valve in response to depression of the thumb-pusher, a flame nozzle metal having an "L"-shaped channel made therein, and fixed to the flame valve via an intervenient electrically conductive gasket, and a shield cap of insulating material enclosing the flame nozzle metal and carrying a high-potential lead wire, which is exposed in the vicinity of the nozzle tip of the flame nozzle metal at one end of the lead wire, and is connected to the piezoelectric unit at the other end of the lead wire. No extra parts other than flame nozzle metals, conductive rubber gaskets, and insulating shield caps are required for assembling piper lighters. The other parts are compatible with those for cigarette lighters. Thus, parts and assembling lines can be used for their fullest extent, and accordingly the cost of production is reduced to possible minimum.
