Cigarette rod: usually made of plastic or metal, it contains components such as batteries and control circuits, which provide power support and basic control functions for the operation of electronic cigarettes. Its shape design is diverse, with long strips similar to traditional cigarettes, and smaller, portable square or other unique shapes, which are convenient for users to hold and carry.
Cigarette cartridge: This is the core part of a disposable electronic cigarette, which stores the smoke oil and atomizer core. The main components of the smoke oil include propylene glycol, glycerin, nicotine (some products contain different concentrations of nicotine, and there are also products without nicotine) and flavors. These components are heated and atomized under the action of the atomizer core to form a smoke effect that simulates smoking. The common materials of the atomizer core are cotton core and ceramic core. The cotton core has a relatively low cost, but the atomization effect and stability may be slightly inferior to the ceramic core; the ceramic core has better atomization uniformity and durability.
