A cigalike e-cigarette currently contains a cartomizer (cartridge atomizer), which is connected to a battery. If the liquid to be atomized contains solids an external mix atomizer may be preferred. An atomizer nozzle can take many forms. The 100 mL bottle includes a spray atomizer. The energy required for atomization is transferred directly from the atomizer body to the liquid. A rotary atomizer comprises a rotating surface. Nickel potentially found in the e-cigarette vapor may originate from the atomizer and heating coils. Now I use an atomizer or an inhaler. It was finally solved by developing an optimized bi-propellant centrifugal atomizer design. This requires an atomizer with an adjustable airflow. The oil can also be sold in pre-filled atomizer cartridges. An atomizer made of plastics could react with e-liquid and leach plasticizers. This same principle is used in a Rotary Atomizer. "Dripping", where the liquid is dripped directly onto the atomizer, can create carbonyls including formaldehyde. A basic rotary atomizer is displayed in the figure.
