An atomizer head is one of the three main components of every electronic cigarette. The other two parts that are always included are the battery and the tank. Essentially, what the atomizer does is turn your e-liquid into vapor. Sometimes the liquid can be sent somewhere else in the device before it is sent to the atomizer for vaporization. The head has a coil inside of it that heats up with the use of a battery. The liquid then turns into a vapor once it is hot enough. The atomizer can also be it the vape device on its own. A soft wick is then used to absorb vape juice and regulate how much liquid is by the atomizer at once. This reduces the chance of breaking the device using excessively heated liquid. This process is called dripping and it either be done manually or by the device.
