Description
Technical field
The utility model relates to a kind of harmful tar that do not contain, and only contains the non-combustible electronic spraying cigarette of nicotine (nicotine).
Background technology
Become under the situation of general knowledge current " Smoking is harmful to your health ", the whole world still has 1,000,000,000 people's smokings at present, and annual this numeral is also enlarging, the international ban on opium-smoking and the opium trade agreement of first that on March 1st, 2003, The World Health Organization (WHO) passed through " (Framework Convention on Tobacco Control ", the numeral that provides according to WHO shows, smoking causes 4,900,000 people's death every year, although smoking can cause serious respiratory disease and cancer, the smoker to give up smoking fully is an exceedingly difficult thing.
The effective ingredient of cigarette is nicotine (being nicotine); the a large amount of tar droplets that produce when nicotine is along with cigarette combustion during smoking absorb rapidly after entering alveolar; nicotine acts on the acceptor of central nervous system after being absorbed into blood; cause similar anti-depressant " euphoria ", as having a dizzy spell or smug sensation that the smoker experienced.
Nicotine is little molecular biosciences alkali, and is harmless substantially to human body under low dose, and the half-life in blood is extremely short.The harmful substance of tobacco mainly is a tar, and tobacco tar is made up of hundreds of compositions, and it is carcinogenic substances that tens of kinds of compositions are wherein arranged.Confirm that at present secondary smoking is bigger to non-smoker's harm.
In order to seek the cigarette substitute that only contains nicotine and do not contain harmful tar, it is to make such as " smoking cessation is pasted " with purer nicotine that many utility models are arranged, " nicotine contains the water of coughing ", " be packaged in the high pressure gas holder spray of propellant ", " nicotinamide chewing gum " products such as " nicotine beverages ", though these products do not have the harm of tar, but because of nicotine absorbs slowly, in blood, can not set up effective peak concentration, can not solve the sensation of demand nicotine " enjoyable ", also deprived simultaneously the custom of " taking out " " suctions " that the smoker formed, thereby the conduct that similar products like can not be real give up smoking articles for use or cigarette substitute.
