History

Electronic Cigarettes are not as new as you might think. The idea first was envisioned by Herbert Gilbert [1] in 1963 when he patented a "smokeless non-tobacco cigarette". In 1967 he was approached by several companies to begin commercialization of his product, however it did not occur.


In 2000, Hon Lik[2], a Chinese chemist, is internationally credited with the invention of the Electronic Cigarette that we are most familiar with. He devised the use of a piezoelectric ultrasound-emitting element to vaporise a pressurised jet of liquid containing nicotine diluted in a Propylene Glycol solution. This design produces a smoke-like vapour that can be inhaled and provides a vehicle for nicotine delivery into the bloodstream via the lungs. He also proposed using Propylene Glycol to dilute nicotine and placing it in a disposable plastic cartridge which serves as a liquid reservoir and mouthpiece. These inventions are the basis of the present-day electronic cigarettes. The device was first introduced to the Chinese domestic market in May 2004 as an aid for smoking cessation and replacement. The company that Hon Lik worked for, Golden Dragon Holdings, changed its name to Ruyan (如烟, literally "Resembling smoking"), and started exporting its products in 2005–2006 before receiving its first international patent in 2007[3].

Current Design

The e-cigarette is composed of a few parts:

  • The cartridge or cartomiser is the part of the cigarette that allows the liquid to be absorbed. Sometimes you may need a drip tip in conjunction with with a cartomiser.
  • The atomiser or cartomiser is responsible for heating the liquid to be vaporized.
  • The unit is powered by a battery. There are automatic batteries which require you to puff in order for the atomiser to be activated. Manual batteries require a button to be pushed to activate the atomiser.
