The e-cigarette atomizer is a heating element that turns e-liquid into vapor. It is usually made up of three parts: the actual heating coil, a mesh bridge and a wick that absorbs e-liquid. The atomizer is also known as a nebulizer.
In order for the atomizer to function properly, the heating coil must be either immersed in liquid or positioned in a heavily saturated atmosphere, or it will overheat. The e-liquid acts as a coolant, keeping the atomizer working at temperatures of around 60 – 70 degrees Celsius. If it doesn’t have enough moisture to cool it down, the atomizer coil will overheat, reaching temperatures of up to 300 degrees Celsius, and eventually fail. Without any liquid to vaporize, it will burn the wick and filling material of the cartridge or cartomizer and melt the atomizer’s internal components. That’s why it’s very important to keep an eye on e-liquid levels at all times
Just a few years ago, there only a couple of different atomizers available on the market, but today there are several types for users to choose from. They differ not only in design and threading, but also in purpose. Although they all basically do the same thing – vaporize e-liquid – atomizers also have distinct properties, like coil resistance, for example, which allow them to either produce more vapor, enhance the flavor or deliver a stronger throat hit.
