How Electronic Cigarettes Work
At first glance the e-cigarette looks just like another cigarette. However, unlike traditional cigarettes, e-cigarettes do not require combustion or flame to be used.
The secret lies within the Electronic Cigarette's structure. It is composed of a rechargeable battery, atomizer (heating element), and cartridge. A sensor or smart chip and an LED that simulates the glowing of a real cigarette is built into the rechargeable Lithium-Ion battery. The cartridge, which also serves as the mouthpiece, is a small tube resembling a traditional cigarette filter. It contains a cotton-like material diluted with a solution of nicotine, propylene glycol and flavoring.
The magic happens inside the cartridge chamber, when a user inhales though the mouthpiece. The heating element is activated by the sensor and a smoke-like vapor is produced the same way you get from smoking a real cigarette. The vapor that is created is a result of the diluted nicotine solution being vaporized by means of the heating element, powered by the battery, which is controlled by the sensor. At the opposite end of the device, the LED simultaneously lights up simulating the glow or burning of tobacco like a real cigarette. The LED is also an indicator when the e-cigarette is in use.
When the vapor that is coming out has been significantly reduced, or is no longer at a satisfactory level, it means the cartridge needs to be replaced. Each cartridge is equal to about 5 or 6 regular cigarettes depending on the user. Same goes with the rechargeable Lithium-Ion battery, if the device has stopped functioning, it means it needs recharging. Most electronic cigarettes come with a charger, however some disposable varieties utilize an alkaline battery and are not capable of being recharged.
