An E-cig, as some will call it, has three primary parts. They are the atomizer, cartridge and the battery unit. This device will use heat to vaporize the propylene glycol liquid and that is how the mist is formed. The user can then exhale the mist just like he would with regular smoke. You can think of the heating process as the same way that a humidifier creates its smoke. The heating element that is used to vaporize the liquid solution is called an atomizer. E-cigarette atomizers will eventually need to be replaced because they wear out. Once this occurs the electronic cigarette will not work properly, and the atomizer will have to be replaced.
The cartridge works very similar to a mouth piece. The cartridge is a small plastic container with openings on each end. It holds an absorbent sponge that is saturated with the liquid solution that is to be vaporized. You will always be replacing these because once the solution runs out you will need to insert another in order for your electronic cigarette to work. The cartridges do not have to be used, and the liquid can be poured directly into the atomizer. This is called “dripping” but you will also require a special mouthpiece that makes this process easier.
The liquid contains the nicotine that your body will ingest. E-juice is the name of the solution used. Some of the flavors that are available are tobacco, menthol and the user can even try some of the specialty flavors that some companies have managed to manufacture. Some of these flavors include chocolate, vanilla and various fruit flavors. There are also specialty liquids that try to mimic the flavor of popular brands of cigarettes. It is also important to know that each liquid has a specific and designated concentration of nicotine. These come in 6mg to 36mg and if you gradually lower your amount of nicotine over time you will be able to eliminate the need to use any type of nicotine product.
You will find that all of the batteries within these ecigarettes are rechargeable lithium batteries. The battery is usually the largest part of the electronic cigarette. The battery will contain an airflow sensor that will trigger the battery to turn on when in use. This prevents the battery from dying and overheating. These devices have different charging methods but some of the more popular ones are AC outlet and USB cables. The final option for a battery is an e-cigarette that is USB-tethered. These E-cigarettes require no battery, but will not work unless they are plugged into a USB port.
Even though many if not most of these electronic devices are designed to look like actual cigarettes there are some with very cool and unique designs. You will also be able to find some that are reusable and others that are disposable. The reusable electronic cigarettes come with refillable parts to allow for someone to continue using the same e-cigarette. The refillable parts are available to buy at the same locations that the electronic cigarettes were purchased. The disposable ones can only be used until the solution runs out. These cannot have the solution refilled therefore it becomes useless.
