Like most consumer goods, e-cigarettes are an invention of mankind. First, thought to be called Herbert · A. Gilbert's Americans invented a device that, by heating the nicotine solution to produce steam gas, produced smoke, and in 1963 Gilbert applied for a patent for the invention.
At the time, however, the invention had not received widespread attention and the product had not been invested in the market, and a few years later it had disappeared from the public eye. In 2003, a Beijing Traditional Chinese medicine named Han Li invented the first nicotine-based e-cigarette product, which principles the use of ultrasound to atomized nicotine diluted by propylene glycol, and then inhaled by smokers into the lungs.
The product was quickly sold by Chinese tobacco companies, a move that also made e-cigarettes market-oriented for the first time as a commodity. Since e-cigarettes do not burn, they do not produce substances such as tar and carbon monoxide, so e-cigarettes are the main reason why many smokers and non-smokers favor them, and some users see e-cigarettes as a solution to quitting and smoking cigarettes.
