What is the atomization principle of electronic smoke?
The principle of traditional physical method is the same as that of humidifier and evaporimeter in daily use:

Atomizing liquid+atomizer heating and non combustion=steam smoke

Main components of tobacco oil

Secrets of Taste and Throat Beating

Both the cigarette rod and the cigarette bomb are the carrier of atomization, and the core that determines the safety and quality of electronic cigarette is tobacco oil, which is also the liquid used for atomization.
Edible propylene glycol (PG)
Edible vegetable glycerin (VG)

Nicotine

Natural tobacco oil ingredients are mostly derived from food raw materials. Next, we will introduce them separately.

The source of the sense of throats - propylene glycol (PG)

Propylene glycol, which accounts for more than 50% of the components of tobacco oil, is an important food additive. In the appendix [2] of the Standard for the Use of Food Additives (GB 2760-2011) issued by the Ministry of Health of China, propylene glycol was approved to be used in "wet flour products (such as noodles, dumpling skin, wonton skin, and baked wheat skin)" and "pastries". Propylene glycol can absorb fragrance and bring a sense of throat attack.

Source of smoke - vegetable glycerin (VG)

VG stands for vegetable glycerin. It is a natural chemical and comes from vegetable oil, so it is safe for vegetarians. It is usually used in electronic liquids to provide a "thick" feeling for steam. It is not only used in skin care products, but also widely used in olive oil, chocolate, cakes and other foods we often contact. At the same time, vegetable glycerin is also the main contributor to the smoke produced by electronic cigarettes.

Taste source - food spice

Including ice cream, beverages, milk tea and various snacks, almost all of our daily food contains essence, and the different flavors of tobacco oil (mango, mint and tobacco) are determined by essence.

Source of addiction - nicotine
Nicotine is commonly known as nicotine. In addition to tobacco, it is also an alkaloid found in solanaceous plants (Solanum), such as tomatoes, eggplants, peppers and potatoes.

40% of smokers and quitters mistakenly believe that nicotine causes cancer, while the evidence shows that nicotine is less harmful to health. Although nicotine is the cause of smokers' addiction, thousands of other chemicals contained in the burning process of cigarettes are the culprits causing all the harm.
