Exploring the working principle of electronic cigarettes: the technological magic of heating and atomization

1. Basic structure of electronic cigarettes

A typical electronic cigarette consists of the following key components:

Battery: Provides electrical energy, usually a rechargeable lithium battery.

Atomizer: The core component responsible for heating the e-liquid.

E-liquid tank: Stores e-liquid, usually containing propylene glycol (PG), vegetable glycerin (VG), nicotine and flavors.

Airflow sensor or button switch: Controls the operation of the atomizer.

2. How do electronic cigarettes work?

(1) Heating process

When the user inhales or presses the switch, the battery supplies power to the atomizer, and the heating wire (Coil) in the atomizer quickly heats up (usually 100-250°C). Unlike cigarettes that burn (600-900°C), electronic cigarettes only heat but do not burn, so they do not produce harmful substances such as tar and carbon monoxide.

(2) Atomization principle

The e-liquid is transported to the vicinity of the heating wire through a cotton core or a ceramic core, and the high temperature instantly atomizes it into tiny droplets, forming an aerosol similar to smoke. Since the temperature is much lower than the combustion point, the components in the e-liquid remain basically stable, and only physical changes occur instead of chemical decomposition.

(3) Airflow control

When the user inhales, the airflow sensor triggers the atomizer to work, and the generated mist enters the mouth with the airflow. Some high-end e-cigarettes support adjusting the air intake to control the smoke concentration and taste.

3. E-cigarettes vs. Traditional Cigarettes

4. Technological development of electronic cigarettes

Temperature control technology: precisely control the temperature of the heating wire to avoid "core burning" caused by overheating.

Ceramic atomization core: compared with traditional cotton core, ceramic core is heated more evenly and has a longer life.

Nicotine salt technology: improve nicotine transmission efficiency and reduce throat irritation.

5. Safe use suggestions

Choose regular brands and avoid inferior e-liquid or batteries.

Do not modify the device by yourself to prevent battery overheating or short circuit.

Long-term use requires attention to possible health effects, and appropriate use is appropriate.

Conclusion

Electronic cigarettes use precise heating and atomization technology to simulate the smoking experience while reducing the production of harmful substances. However, its long-term health effects still need more research. Understanding its working principle will help users use electronic cigarette products more safely and reasonably.
