Lighter or Lighting Gun with a Safety Switch

Abstract

The invention provides a lighter with a safety switch, comprising: a housing, a fuel container within the housing, a piezoelectric assembly, and a vent assembly. The piezoelectric assembly comprises a piezoelectric element, a snap, as well as a upper and lower push rods arranged between the snap and piezoelectric element. The lower part of the upper push rod and the upper part of the lower push rod are connected in a manner that they can deviate from the centerline of the upper and lower push rods toward one side. Thus, the upper and lower push rods can bend to one side at the joint during the operation of the snap. The lighter further comprises a safety switch, which can prevent the upper and lower push rods from bending.
