History of electronic cigarette
A fact you may not have expected: although someone made the prototype of e-cigarette a long time ago, the modern e-cigarette we see now was not invented until 2004. Moreover, this seemingly foreign product is actually "export to domestic sales".
Herbert A. Gilbert, an American, obtained a patented design of a "smokeless, non tobacco cigarette" in 1963. The device heats liquid nicotine to produce steam to imitate the feeling of smoking. In 1967, several companies tried to produce the electronic cigarette, but because the harm of paper cigarette had not been paid attention to by the society at that time, the project was not really commercialized in the end.
In 2000, Dr. Han Li in Beijing, China proposed diluting nicotine with propylene glycol and atomizing the liquid with an ultrasonic device to produce a water mist effect (in fact, atomizing gas is produced by heating). Users can suck nicotine containing water mist into their lungs and deliver nicotine to blood vessels. The liquid nicotine diluent is stored in a device called smoke bomb for easy carrying, which is the prototype of modern electronic cigarette.
In 2004, Han Li obtained the invention patent of this product. The following year, it began to be officially commercialized and sold by China Ruyan company. With the popularity of anti smoking campaigns abroad, e-cigarettes also flow from China to European and American countries; In recent years, China's major cities have begun to implement strict smoking bans, and e-cigarettes have slowly become popular in China.
Recently, there is another kind of electronic cigarette, which generates smoke by heating tobacco through heating plate. Since there is no open fire, it will not produce carcinogens such as tar produced by cigarette combustion.
