Patent ID: RE42750

Claim:
A piezoelectric lighter, comprising: a casing having a liquefied gas cavity defined therein and a cap cavity; a gas ejecting tip appearing from a ceiling of said casing and communicating with said liquefied gas cavity; a windshield mounted on said ceiling of said casing and encircling said gas ejection tip; a piezoelectric unit which is fitted in said casing having an igniting tip connected thereto; a thumb-push cap, which is fitted in said cap cavity of said casing in a vertically movable manner, exposing a top portion thereof above said casing and being attached to a top end of said piezoelectric unit; and a safety apparatus which comprises a pressure absorbing device vertically held between said thumb-push cap and said ceiling of said casing, wherein said pressure absorbing device comprises a cylindrical rubber post deformable resistance piece capable of providing a first elastic force and a soft elastic spring an elastic element capable of providing a second elastic force, smaller than said first elastic force, coaxially attached to said cylindrical rubber post deformable resistance piece for urging said thumb-push cap at an upper normal position thereof and providing a press resistance to said thumb-push cap; a holding means element integrally affixed to an interior surface of said thumb-push cap for rigidly holding one end of said pressure absorbing device in position; and a receiving means element provided in said cap cavity for receiving and supporting another end of said pressure absorbing device in position, wherein said press resistance is an additional upward force added to said thumb-push cap in addition to that provided by said piezoelectric unit.
