Description

A smokeless electronic cigarette

technical field

The utility model relates to the field of tobacco, and belongs to an electronic smoking device, specifically a smokeless electronic cigarette.

technical background

With the deepening of research on smoking and health, some scientific studies have shown that most of the harmful substances in cigarettes are produced by burning tobacco and enter the human body through smoking. Current research also shows that there are more than 2,740 kinds of components in the smoke produced by tobacco combustion, which are mainly produced by pyrolysis of tobacco. The most difficult thing for non-smoking people to accept is that the passive smoking that causes harm to others due to smoking is also mainly caused by the sidestream smoke produced by burning cigarettes. Therefore, the public is particularly resistant to smoking, especially smoking in public places, and a social consensus has gradually formed. As one of the member states of the World Health Organization, my country has signed the "Framework Convention on Tobacco Control." However, although the view that smoking is harmful to health has been accepted by the public, due to the unique charm of tobacco, the total number of smoking populations in the world is still on the rise. Therefore, while recognizing that smoking is harmful to health, it is particularly necessary to develop a safer smoking method that can meet the special needs of smokers and reduce the harm of smoking to the public.

However, due to consumption habits, traditional smokeless tobacco products (smokeless tobacco) such as chewing tobacco and snuff cannot be accepted by consumers. At present, these products only have certain consumers in foreign countries. Not many yet. Moreover, this type of product cannot provide the real feeling of holding a cigarette when smoking a cigarette, and at the same time, some flavor substances in tobacco that can only be released by heating cannot be released. In addition, the safety of this type of product is also currently under debate. Therefore, the development of a tobacco form that does not produce sidestream smoke and allows tobacco consumers to enjoy the unique fragrance of tobacco has become a current research focus.

The new smokeless smoking devices disclosed in Chinese patents 93115275.5, 96104954.5 and 96118402.7 can solve the problem of sidestream smoke to a certain extent, but they either use non-tobacco materials or tobacco essential oil extracts, and provide them to smokers in the form of atomization , unable to provide tobacco consumers with a sense of satisfaction when smoking cigarettes, and at the same time, the flavor of cigarettes is also insufficient. Chinese patents CN88101196 and 89108679.X applied by Reynolds Tobacco Company provide a cigarette that provides tobacco flavor by heating rather than by burning tobacco or any other material. However, this tobacco product tends to have a burning carbon tip and thus the amount of CO in the smoke is higher. Makes it more expensive due to the special carbon tip. U.S. Patent No. 4714082 discloses a smoking appliance that uses glass fiber insulation to surround fuel and smoke generators, and generates smoke by heating. However, due to the use of elastic glass fiber heat insulation sleeves, it is difficult to carry out modern-scale mechanical production. In addition, During the process of production and transportation, the glass fiber is easy to fall off, and may be sucked into the mouth of the smoker, causing danger. Chinese patents 91105820.6, 95190277.6, and 96194107.3 applied by Philip Morris Tobacco Company disclose a smoking appliance using a sleeve-type electric heating device. The possibility of generating sidestream smoke is avoided. Yet this device adopts higher temperature to heat shredded tobacco when in use, makes shredded tobacco close to carbonization, thereby becomes loose, falls off easily in the sleeve and is difficult for removing, brings inconvenience to reuse. Simultaneously this device design is complicated, and cost is higher, and non-general consumer can accept.
