On May 1, 2022, the Measures for the Administration of E–Cigarettes was officially implemented. E-cigarette is not only a tobacco product that is strictly regulated, but a product of cutting-edge technology in the era of highly developed economy.

It has attracted people’s attention with a global market for more than 108 billion USD scale, someone might be curious about how to make it and puff the smoke?

STRUCTURE

Smoke bomb, smoke rod, atomizer

Actually, as earlier in 2016, The New England Journal of Medicine introduced the structure and principle of e-cigarettes in its October issue of the Health Effects of Electronic Cigarettes: e-cigarettes are mainly composed of three parts:

cigarette cartridge (containing e-liquid and mouthpiece), cigarette rod (containing battery) and the atomizer which is the most important structure among them, its core component, the atomization core, plays a key transformation role in process.

Take the latest R&D achievement of HCD, COTTONX Atomization Core, as an example. We are wondering that what kind of process has it gone through of this precision industrial product with a length of only 2.3 cm will transform the e-liquid into smoke and take an extraordinary experience for user with its tiny body?

ATOMIZATION

[cigarette atomizing]

We should understand the “atomizing” firstly if we want to explore the mystery of atomization core, Atomizing is disperse liquid into tiny droplets or aerosols, which can be achieved by high temperature, high pressure or high-speed air flow.

Electronic atomizer takes the high temperature method to making the e-liquid into smoke, which is actually aerosol. Aerosol is suspended in the air and no longer maintaining the original liquid form of the e-liquid, but a mixture of solid and liquid.

A study has proved that the main products of e-cigarette is propylene glycol, glycerol and nicotine, the sum of the three content in 80 ℃, 150 ℃, 250 ℃, 300 ℃, 500 ℃ and 900 ℃ atomizing conditions accounted for 99.66%, 96.66%, 99.53%, 99.35%, 97.25% and 98.92% of the total,

which is basically no difference with the main components of the e-liquid. This means that the atomizing process basically does not occur chemical reactions, it seems to be smoking “smoke”, in fact, the inhalation is still atomized liquid, does not contain the cracking products produced by traditional cigarette combustion.

EXAMPLE

Take COTTONX atomization core as an example

The workflow of e-cigarette can be briefly described as follows: user inhales → airflow sensor  senses airflow, turns on battery → activates atomizer → the atomizer heats e-liquid, reaches boiling point, and atomizes it into “vapor”.

After we know the vaping principle of e-cigarettes, let’s look at the real thing.

Atomizer inside working flow since puffing:

· E-liquid enters from the liquid guide hole in all directions at 360 degrees, and is evenly soaked with oil guide cotton sheets woven by long-staple cotton;

· High-precision heating wire imported from Sweden is inserted into the cotton piece and heats up within 0.01 seconds after being connected to the power supply.

· Sufficient e-liquidin cotton piece is heated rapidly and volatilized at high temperature to form smoke;

· The smoke is inhaled by the product through the air outlet, bringing fine, pure and highly reducible atomized molecules to users;

· When the temperature exceeds 260 degrees, the heating element automatically outputs a signal to the power supply then cut it off to avoid burning the core.

The working process of COTTONX seems in simple way, but in fact there are hidden secrets everywhere.

EXPECTATION

HCD Huachengda Helps the Development of Atomization Industry

The e-cigarette industry is still in the process of rapid development, it is not only intermingled with the tobacco industry to produce such high-tech products as e-atomizer, but also can be applied to the field of health, atomizing treatment, beauty etc.

HCD as rooted in the atomizing industry chain for 15 years, as a part of Chinese atomization enterprises with responsibility and mission, we have the confidence, professionalism and ability to promote the R&D and production in the field of atomization cores, achieve leapfrog progress in the e-atomizing industry, and help the manufacturing supply chain in the field of e-atomizing in China to maintain a vigorous innovation and core leadership.

How to avoid burning the core? How to extend the service life of atomization core ? How to highly restore the flavor of e-liquid ?  Please waiting for next issue.
