Abstract
A piezoelectric lighter includes a lighter housing having a liquefied gas storage, a gas emitting nozzle extended from the liquefied gas storage, a piezoelectric unit disposed in the lighter housing, and a lighter cap slidably coupled on top of the lighter housing above the piezoelectric unit. The gas emitting nozzle is slidably received at a nozzle window of the lighter cap, wherein an exit opening of the gas emitting nozzle is embedded in the ceiling of the lighter cap to protect the exit opening of the gas emitting nozzle. When the lighter cap is depressed to expose the exit opening of the gas emitting nozzle above the ceiling of the lighter cap, the piezoelectric unit is depressed and the gas emission unit is actuated at the same time to produce a flame at the exit opening of the gas emitting nozzle.
Claims20
A lighter, comprising:
- a lighter housing having a liquefied gas storage;
- a gas emission unit for controlling a flow of gas, wherein said gas emission unit comprises a gas emitting nozzle extended from said liquefied gas storage;
- a piezoelectric unit disposed in said lighter housing for generating sparks when said piezoelectric unit is depressed;
- and
- a lighter cap slidably coupled on top of said lighter housing at a position above said piezoelectric unit and being moved between a non-ignition position and an ignition position, wherein said lighter cap has a depressible surface that an exit opening of said gas emitting nozzle is slidingly extended to embed in said lighter cap so as to protect said exit opening of said gas emitting nozzle at said non-ignition position, wherein when said lighter cap is depressed at said depressible surface to said ignition position to expose said exit opening of said gas emitting nozzle above said ceiling of said lighter cap, said piezoelectric unit is depressed and said gas emission unit is actuated at the same time for releasing the gas to be ignited by the sparks so as to produce a flame at said exit opening of said gas emitting nozzle.
A gas emission actuation device for a lighter which comprises a lighter housing having a liquefied gas storage and a piezoelectric unit disposed in the lighter housing for generating sparks when the piezoelectric unit is depressed, wherein said gas emission actuation device comprises:
- a gas emission unit for controlling a flow of gas, wherein said gas emission unit comprises a gas emitting nozzle arranged for extending from the liquefied gas storage;
- and
- a lighter cap arranged for slidably coupling on top of the lighter housing at a position above the piezoelectric unit, wherein said lighter cap has a ceiling having a depressible surface, wherein when said lighter cap is depressed at said depressible surface to expose said exit opening of said gas emitting nozzle above said ceiling of said lighter cap, said lighter cap is arranged for depressing the piezoelectric unit and for actuating said gas emission unit at the same time to release the gas to be ignited by the sparks so as to produce a flame at said exit opening of said gas emitting nozzle.
An ignition method of a lighter, comprising the steps of:
- (a) embedding an exit opening of a gas emitting nozzle in a ceiling of a lighter cap at a non-ignition position that said lighter cap is slidably coupled on top of a lighter housing at a position above a piezoelectric unit;
- and
- (b) exposing said exit opening of said gas emitting nozzle from said ceiling of said lighter cap at an ignition position by applying a depressing force on a depressible surface on said ceiling of said lighter cap to depress said piezoelectric unit and to actuate said gas emitting nozzle at the same time so as to produce a flame at said exit opening of said gas emitting nozzle.
