Abstract:
A piezoelectric lighter, comprising:a casing receiving a liquefied gas storage;a gas emitting nozzle in 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 close 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; andan ignition cap slidably mounted on said ceiling of said casing in a rotationally movable manner wherein said ignition cap is attached to a top end of said piezoelectric unit and arranged in such a manner that when said ignition cap is rotated sidewardly and downwardly at said same time, said movable operating part of said piezoelectric unit is depressed to ignite said piezoelectric lighter;a safety arrangement, comprising:a locker cavity provided at a side portion of said ignition cap and positioned above said piezoelectric unit, wherein a guiding slot is provided on said ignition cap to communicate said locker cavity with an exterior of said ignition cap;a locking member comprising a locking latch disposed in said locker cavity and an operation button extended from said locking latch to said exterior through said guiding slot, wherein said locking latch is movably fitted in said locker cavity in such a manner that said locking latch is arranged to be driven by said operation button to move from a normally locked position to an unlocked position; anda resilient element which is disposed in said locker cavity for applying an urging pressure against said locking member so as to normally retain said locking member in said locked position, wherein at said locking position, a locking portion of said locking latch is extended into said casing for blocking up said ignition cap from being slid sidewardly with respect to said casing, so as to lock up said ignition cap from ignition, and that in said unlocked position, said locking portion of said locking latch is moved away from said casing so as to release said blocking up of said ignition cap with respect to said casing, so that said ignition cap is capable of being slid sidewardly to ignite said piezoelectric lighter.
