Abstract:
A piezoelectric lighter, comprising:a casing receiving a liquefied gas storage; a gas emitting nozzle appearing at a ceiling of said casing and communicating with said liquefied gas storage for controlling a flow of gas; a piezoelectric unit, which is disposed in said casing for generating piezoelectricity, comprising a movable operating part extended upwardly and an ignition tip extended to a position adjacent to said gas emitting nozzle, wherein when said movable operating part is depressed downwardly, said ignition tip generates sparks to ignite said gas emitted from said gas emitting nozzle at said same time: and a child resistance arrangement, comprising: a top end of said casing integrally provided with a pair of protective walls which are upwardly extended from said ceiling to a rear wall of said casing, wherein each of said protective walls has an inner surface and a receiving chamber is defined between said two inner surfaces of said two protective walls and positioned above said piezoelectric unit; and an ignition button slidably mounted and extended between said inner surfaces of said protective walls inside said receiving chamber in a radially movably manner wherein said ignition button is coupled with said movable operating part of the piezoelectric unit and arranged to depress said movable operating part of said piezoelectric unit to ignite said piezoelectric lighter when said ignition button is depressed sidewardly and downwardly simultaneously; wherein said ignition button is mounted to position below top ceilings of said two protective walls to form a physical safety groove having a predetermined depth above said ignition button and between said two protective walls that acts as a physical barrier to prevent a thumb of a child from fully engaging said ignition button to ignite said piezoelectric lighter.
