An atomizer consists of a small heating element, the coil, which vaporizes the e-liquid of the electronic cigarette, called e-liquid, and a breathable material that inhales liquid onto the coil.

When the user vape activates a sensor that detects the flow. The liquid is heated, atomizing the liquid solution; Most devices are activated manually by a button. The e-liquid reaches a temperature of approximately 100-250 ° C inside the chamber.

This is why the typical thick smoke of the electronic cigarette is made.
