Electronic cigarette, an e-cigarette, an e-cig or a vaporizer is more or less reminiscent of the shape of the actual cigarette and its smoke. The electronic term is a marketing term invented in 2005 for devices that did not at the time contain any electronic elements. In 2013, most of the batteries in these devices are actually equipped with electronic circuits, from simple protection to sophisticated models, with voltage puff count, display screen, communication with a computer… When the electronic cigarette takes the form of a cigar or pipe, it can also be called electronic cigar or electronic pipe. It can take other forms even more original. Users of electronic cigarettes use the terms vapoter or vaper (derivatives of the vapor word) instead of smoking and designate themselves as vapotors .
The Beginnings of the Electronic Cigarette
The concept of the electronic cigarette was invented by Herbert A. Gilbert in 1963, patented in 1965, a small device replacing tobacco and paper with heated and flavored air. This invention was never commercialized. The first commercially marketed electronic cigarette to simulate the use of a real cigarette was made in 2003 by Hon Lik, a Chinese pharmacist and engineer who patented a smoke-free electronic smoke cigarette in 2005. This first device exploits ultrasonic nebulization technology. Heated resistance vaporization technology, the technology marketed for electronic cigarettes currently, was invented in 2009 by Chinese David YunqiangXiu with his Electronic Nicotine Delivery System (ENDS). Most electronic cigarettes are manufactured in China.
There are also models developed and manufactured in small series in Europe and the USA. Principle The principle of an electronic cigarette is to produce an aerosol that mimics tobacco smoke. The most used technique consists in heating the ejuice which has the property of evaporating at a temperature close to 60 ° by the action of a heating resistor, also called an atomizer.
The sprayer must activate the heating of the resistance, the liquid heats up, vaporizes and produces an aerosol that the sprayer can inhale. Activation of the heating of the resistance can be either manual (the sprayer presses a switch) or automatic (an electromechanical device placed in the electronic cigarette detects the aspiration of the sprayer and immediately activates the resistance). The aerosol constitutes a cloud recalling the smoke of a real cigarette, little odorant. This visible vapor disappears rapidly, mainly through evaporation. Elements of an Electronic Cigarette There are a large number of models of sizes, capacities, shapes, contents, accessories and brands. From disposable electronic cigarettes or early models that often looked for resemblance to traditional cigarettes to the latest models whose appearance can be strongly away from references to tobacco.
