The basic structure of pen style electronic cigarettes
Electronic cigarette pens typically contain a small number of important components. These sections include:
A blowing mouthpiece
A battery
Electronic liquid chamber or smoke bomb
Nebulizer or heating element
microprocessor
Button to initiate the vaporization process
Some models are equipped with LED display screens that can show when the device is active
Most e-cigarette pen models include rechargeable batteries. You can keep a backup battery to prevent the device from running out of battery. Some e-cigarette products offer portable battery charger boxes and even wireless charging functions.
Some models are purely mechanical and do not have electronic components. Mechanical action switches control these.
