Benefits of technology

[0007]The main object of the invention is to provide a lighter thereof has a hard-spring piezoelectric unit includes a plunger which includes auxiliary spring surrounding the plunger for increasing a force needed to actuate the piezoelectric unit and a blocking means for fixing the auxiliary spring with respect to the piezoelectric unit. The blocking means is able to prevent the auxiliary spring from falling off from a plunger of the piezoelectric unit in assembly procedures therefor enhancing an assembly efficiency of the gas lighter in manufacturing.

Problems solved by technology

However, such deployment has a drawback.
In either process, the helical auxiliary spring is very liable to fall off from the plunger of the piezoelectric unit in both conveyance and all other working procedures with the additional spring being surrounding.

Embodiment Construction

[0015]With reference to FIGS. 1 and 2, they show the preferred embodiment of a gas lighter of the present invention. The gas lighter has a fuel-storage chamber 10 for containing liquefied gaseous fuel 11, an upliftable gas release nozzle 20 mounted on the fuel-storage chamber 10, a piezoelectric unit 30 having a main casing 31 installed in the fuel-storage chamber 10 and a shaft like plunger 32 which when pressed downward, is able to actuate the piezoelectric unit 30 to generate sparks for ignition, an auxiliary spring 33 surrounding the shaft like plunger 32, a blocking means 34 fixed to a top end of the plunger 32, an ignition trigger 40 having an inner lower part 41 meeting the top end of the plunger 32, and a linking lever 50 which when the ignition trigger 40 is depressed, is able to uplift the gas release nozzle 20 to release the gaseous fuel 11 and at the same time depress the plunger 32 of the piezoelectric unit 30 to generate sparks. The gas release nozzle 20 is so position...

Abstract

A lighter that includes a hard-spring piezoelectric unit for preventing children from to operate lighter. A piezoelectric ignition unit has a plunger that is movable into a main casing to generate sparks for igniting a stream of flammable fuel. A hard-spring piezoelectric unit includes a plunger which includes auxiliary spring surrounding the plunger for increasing a force needed to actuate the piezoelectric unit and a blocking means for fixing the auxiliary spring with respect to the piezoelectric unit therefore enhancing an assembly efficiency of the gas lighter in manufacturing.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a lighter, and more particularly, to a lighter that includes a hard-spring piezoelectric unit for preventing ignition of lighter. A piezoelectric ignition unit has a plunger that is movable into a main casing to generate sparks for igniting a stream of flammable fuel. A hard-spring piezoelectric unit has a plunger which includes auxiliary spring surrounding the plunger for increasing a force needed to actuate the piezoelectric unit and a blocking means for fixing the auxiliary spring with respect to the piezoelectric unit therefor enhancing an assembly efficiency of the gas lighter in manufacturing.[0003]2. Description of the Prior Art[0004]Gas lighter is a common utility for ignition. A conventional gas lighter usually has a fuel-storage chamber for containing flammable fuel, an upliftable gas release nozzle mounted on the fuel-storage chamber, a piezoelectric unit having a main casing and mova...
