Description

  • This application claims the priority of the China Patent Application No. 201310625207.3, filed with the Patent Office of China on Nov. 28, 2013, titled “A SOLVENT FOR ELECTRONIC CIGARETTE LIQUID AND AN ELECTRONIC CIGARETTE LIQUID”, the contents of which are incorporated herein by reference in its entirety.
  • FIELD OF THE INVENTION
  • The present invention relates to the technical field of electronic cigarette, and particularly to a solvent for electronic cigarette liquid and an electronic cigarette liquid.
  • BACKGROUND OF THE INVENTION
  • An electronic cigarette liquid is an essence extracted from a plant, to which an edible flavor is added. It has a strong antioxidant activity, and is free of harmful substances such as carbon monoxide and tar. The electronic cigarette liquid mainly comprises a solvent, a tobacco flavor and/or fragrance, and a tobacco extract. The traditional tobacco smoke contains toxic substances such as carbon monoxide, nitrous oxide, formaldehyde, ethanol, methane, toluene, hydrogen cyanide, lead, aluminum, zinc, magnesium, etc., and carcinogenic substances such as benzopyrene, chloroethylene, nitrosamine, polycyclic aromatic hydrocarbons, nitrosotoluene, cadmium, nickle, polonium 210, etc. However, the electronic cigarette liquid is heated by electric heating, in order to atomize a solution comprising a flavor into atomized particles. Smoke can be generated upon suction, which provides a feeling of smoking. However, it neither burns nor generates new harmful substances. Therefore, the electronic cigarette liquid is healthier than the traditional cigarettes. Using of the electronic cigarette liquid instead of the traditional cigarette can reduce harm and avoid pollution of second-hand smoking, and represents a great progress in the development of tobacco.
  • The electronic cigarette liquid is a liquid utilized in the electronic cigarette cartridge. An electronic cigarette comprises a battery, an atomizer and a cartridge, and works as follows: the cartridge directs the liquid into the atomizer—the atomizer is energized by the battery—the atomizer is heated to evaporate the cigarette liquid into atomized particles. The electronic cigarette liquid has strict requirements on its components: the solvent must be of food or pharmaceutical grade; the flavor for the electronic cigarette must be of high quality. At present, propylene glycol and glycerol are mainly used as the solvent for the electronic cigarette liquid. However, the smoke formed by such electronic cigarette liquid is greasy. In addition, glycerol is characterized by water absorption, readily renders a dry throat of the smoker, and thus results in a poor experience of the smoker.
  • SUMMARY OF THE INVENTION
  • The object of the present invention is to provide a solvent for electronic cigarette liquid and an electronic cigarette liquid. The smoke formed by the electronic cigarette liquid which is prepared with the solvent for electronic cigarette liquid provided by the present invention is not greasy, neither too dry nor too wet.
