Iteration of ceramic and cotton wicks
The core component in an e-cigarette is the atomising core, and the more common ones used in mainstream applications are cotton and ceramic cores. Atomisation technology involves heating the liquid infiltrated/stored in the cartridge through a heated wire or heating film, which heats the liquid to form a mist; the performance of the cartridge determines the flavour reduction, the atomisation effect, and the proportion of harmful substances released.
Cotton Wick
Cotton wicks were developed earlier in the application of electronic cigarettes, are more widely used, and are less expensive than ceramic wicks.
The first generation of atomising core uses glass fibre rope to resist high temperature and absorb oil with good oil-conducting effect, and is made up of glass fibre rope wrapped around a heating wire to form an atomising core;
The second generation of cotton fibre, eliminating the potential harm of glass fibre to human skin irritation, while the oil storage effect is also better, but the structure of the heating wire will still be wrapped around the cotton rope, heat consistency is poor, there is a paste core, oil leaks and other risks, the taste and customer experience impact.
The latest generation of cotton cores, such as Huachengda's products, use cotton sheets wrapped around a mesh heating grid, which enhances the temperature control effect and reduces the risk of core gluing caused by the deformation of the heating wire.

Ceramic core
Using the excellent adsorption of microporous ceramic materials, we can prepare ceramic atomised wicks with better oil-conducting and liquid-locking functions. Compared with cotton wicks, the temperature uniformity and controllability are better.
The first generation of ceramic Atomizer core is the cCELL atomizer core launched in 2016 by Smallscale International, which is sintered and shaped by the moulding injection process, and surrounded by the outer side of the heating wire; the second generation of ceramic atomizer core is made of FCC, FCC, FCC, FCC, FCC, FCC and FCC.
The second generation of ceramic atomiser cores is the Feelm, which further reduces the pore size of the substrate to form finer and more uniform atomised particles to enhance the taste, and the S-shaped heating film is attached to the ceramic surface to improve the heating uniformity and avoid localised carbonisation to produce a burnt taste; the third generation of ceramic atomiser products is the cCELL, which was launched by Smallmoor International in 2016.
The third generation of ceramic atomisers is the Feelm air, which uses a composite bionic film. In 2022, Smallmole International will launch a new generation of ceramic atomisation solutions based on nano-sized vacuum lamination technology: seven 2-micron thin film ceramic layers are stacked on top of each other to form an atomising core, which is 25% thicker than its predecessor, but still maintains the same amount of atomisation and battery capacity.
Thin-film heating layer: precision alloy heating layer, to achieve rapid temperature rise while taking into account the corrosion resistance of the material, to reduce the precipitation of heavy metals; temperature-controlled thermal conductivity layer, the formation of a gradient temperature field, different boiling points of the aroma substances can be atomised at the corresponding temperature, to enhance the taste of the restore degree: plus porous insulation layer, to reduce the loss of heat.
The outermost nano-protection layer further prevents the corrosion of the heat generator when the atomised liquid is aerated and reduces the precipitation of heavy metals. The porous freshness locking layer can control and refine the atomised particle size during the atomisation process.

In addition, the bionic structure of the liquid locking layer controls droplet sputtering in the suction process and improves leakage prevention performance. Nano-silver plating layer can prevent local high temperature and reduce conduction energy self-loss.
