As an emerging alternative to smoking, e-cigarettes have attracted widespread attention. This article will delve into the working principle of e-cigarettes, reveal the scientific and technological mysteries, and provide readers with popular science knowledge about the working principles of e-cigarettes.
1.1 Battery: As the power source of the e-cigarette, it provides energy to heat the liquid.
1.2 Atomizer: includes components such as heating coils and graphite rods, which are responsible for converting liquid into inhalable mist.
1.3 Liquid storage tank: Contains liquids containing nicotine and flavorings.
2.1 Inhalation activation: When the user inhales, the e-cigarette senses the airflow and automatically activates.
2.2 Heating the liquid: The battery provides electrical energy to heat the heating coil, thereby heating the liquid in the atomizer.
2.3 Atomization generation: The heated liquid quickly turns into smoke and is output through the nozzle.
2.4 Inhalation experience: Users inhale the smoke generated through the nozzle to obtain a smoking-like feeling.
3.1 Nicotine content: The nicotine content in e-cigarette liquid can be adjusted according to personal needs, including high, medium, low and no nicotine options.
3.2 Flavorings: In order to increase taste and appeal, various flavorings, such as fruits, mint, etc., are usually added to e-cigarette liquids.
4.1 Combustion method: Traditional cigarettes produce smoke through combustion, while e-cigarettes produce steam by heating liquid.
4.2 Odor and residue: The vapor produced by e-cigarettes is lighter than traditional cigarettes, has less odor, and has no ash and residue.
4.3 Nicotine content: The nicotine content of e-cigarettes can be adjusted according to personal needs, while the nicotine content of traditional cigarettes cannot be adjusted
In addition to nicotine and flavorings, the liquid storage tank of an e-cigarette also contains a liquid called e-liquid or e-cigarette oil. E-liquids contain a variety of ingredients, including propylene glycol, glycerin, flavors and other chemicals. Alcohol is sometimes added, but this practice is controversial. There are also many types of e-liquids, such as popular flavors including strawberry, banana, chocolate, etc.
While e-cigarettes are in some ways safer than traditional cigarettes, they are not completely harmless. Although there is currently no direct evidence that e-cigarettes cause cancer or other serious illnesses, some studies have linked e-cigarette use to adverse health outcomes such as airway irritation, dry cough, shortness of breath, dizziness, nausea and heart palpitations.
The ingredients and flavors of e-cigarettes make them more likely to attract the attention of minors. Therefore, in some countries and regions, the sales and use of e-cigarettes are strictly restricted or even banned to protect minors from the harm of nicotine.
