What is electronic cigarette

Electronic cigarette is an electronic product that imitates cigarettes, with the same appearance, smoke, taste and feeling as cigarettes. It turns nicotine into vapor through atomization and other means for users to smoke. Its main purpose is to replace cigarettes and help quit smoking.

The electronic cigarette is generally composed of lithium battery, electronic atomizer and smoke bomb. Its working principle is very simple: the electronic atomizer transforms the smoke liquid in the smoke cartridge into fog by heating, so that the user has a similar feeling of smoking. The quality of cigarette oil, battery power and quality of atomizer are the main factors that affect the taste and smoke volume of electronic cigarette, so good cigarette oil and atomizer should be selected. The cigarette gun is also very important. The cheap cigarette gun has a bad atomization effect on the cigarette oil, so the taste will be very bad.

Cigarette oil is a consumable used with electronic cigarettes. For tobacco oil, you may have heard people talk about the proportion of PG and VG, but you don't know what they are. In short, PG, also known as propylene glycol, and VG, also known as vegetable glycerin, are tasteless liquids. They can be used to make the tobacco oil of electronic cigarettes by dissolving the essence and nicotine. When smoking electronic cigarettes, 0.5~1ml of tobacco oil is generally required at a time. Use a pointed bottle to drop the smoke oil into the atomizer and shake it well. The heating of the atomizer produces smoke similar to that of cigarette burning. There are many types of tobacco oil, and smokers can choose according to their own preferences.

What's in the electronic cigarette? The main components of tobacco oil are propylene glycol (PG), vegetable glycerin (VG), tobacco flavor, nicotine and additives. Some electronic cigarette oils also contain nicotine, mainly to make their taste closer to cigarettes.

Propylene glycol is a colorless and tasteless liquid, which is used to provide a "sense of throatsmanship", that is, to simulate the irritation of the throat when smoking. At the same time, because it is more effective than vegetable glycerin in the aspect of miscible flavor, it is often used as the solvent for flavor and nicotine. Because of the existence of propylene glycol, people will have dry mouth, sore throat, thirst and other symptoms when smoking electronic cigarettes.

Vegetable glycerin is a natural chemical derived from vegetable oil, which is widely used in food and medicine and is safe for human body. The liquid is slightly sweet and much thicker than propylene glycol. After being heated, vegetable glycerin will produce a large amount of fog, which can produce thicker steam in the tobacco oil used for electronic cigarettes. Compared with the tobacco oil with a high proportion of propylene glycol, the tobacco oil with a high proportion of vegetable glycerin has a smoother throat strike feeling, and is more suitable for electronic cigarettes with low resistance.

The essence is to provide a variety of flavors for the tobacco oil. There are generally three flavors of tobacco oil: tobacco flavor, fruit flavor and herb flavor. The tobacco flavor is generally similar to the existing cigarettes, such as Zhonghua, Yuxi, Marlboro and other traditional cigarettes. There are many fruit flavors. Common fruits such as apples, lemons, strawberries, watermelons, etc. can be imitated. Herbal taste is similar to the taste of herbaceous plants, such as mint, vanilla, licorice, etc.

The main role of nicotine is to alleviate the addiction to tobacco and produce a sense of throat attack. The common concentrations of nicotine in tobacco oil are 0mg, 6mg, 12mg and 18mg. The higher the number, the higher the nicotine concentration in each milliliter of tobacco oil, and the stronger the sense of throat attack. Those who are addicted to smoking can choose those with high concentration, and gradually get rid of nicotine from high to low, so as to quit smoking.

Additives include sweeteners, acidizers, throat wetting agents, deionized water (distilled water), etc. The main role of additives is to improve the taste of tobacco oil and make up for the lack of flavor.

Different proportions of components in tobacco oil will also produce different flavors. The proportion of propylene glycol and vegetable glycerin in the tobacco oil can bring different taste and throat beating feeling when smoking electronic cigarettes. For example, to obtain a strong sense of throat, you can use tobacco oil with a high proportion of propylene glycol; To obtain smooth taste, use the tobacco oil with a high proportion of vegetable glycerin; To obtain large smoke, use tobacco oil with the highest proportion of vegetable glycerin as possible, or use pure vegetable glycerin liquid.
