Cigarette lighters. Lighter for cigarettes.

There exist plenty of varieties of cigarette lighters in the world. However they have a general principal of work.

A cigarette lighter is a compact gadget used to cause a flame. Usually it consists of a metal or plastic box filled with lighter liquid (usually naphtha or liquid butane under pressure), as well as a means of inflammation and some supply for quenching the flame, either by taking away it of air or of fuel. A butane cigarette lighter flame averages 750 degrees Celsius.

Cigarette lighters using naphtha possess a wick which is drown in the liquid and becomes satiated. This type usually has a filament packing material, which assimilates the liquid to prevent it from dripping.

They also should have a covered top to avoid the volatile liquid from disappearing, and to accessibly extinguish the flame. Butane lighters have a valved opening that as it escapes as a gas.

A sparkle is produced by striking metal against a flint, or by squeezing a button that compresses a piezoelectric crystal, producing a voltaic arc. In naphtha cigarette lighters the liquid is volatile enough that deflagrable gas is present as soon as the top of the cigarette lighter is opened. Butane cigarettes lighters combine the striking action with the opening of the valve to acquit gas. The sparkle burns the deflagrable gas causing a flame to come out of the cigarettes lighter which continues until either the top is closed (naphtha type), or the valve is acquitted (butane type).

A metal enclosure with air punctures generally surrounds the flame, and is designed to permit mixing of fuel and air while making the lighter less reactive to wind. The high energy jet in butane cigarette lighters permits mixing to be achieved by using Bernoulli's principle, so that the air hole in this type attends to be much smaller and farther from the flame.
