The working principle of the atomizing core is that the oil storage cotton is wrapped around the atomizing core, the cotton is soaked in e-liquid, the heating wire conducts electricity and conducts heat, and the e-liquid evaporates to produce smoke.

So, how to make the atomizing core work better, have a longer lifespan, and provide customers with a more satisfactory experience? This has always been the goal of HCD's R&D department day and night.

The secret to good taste

In the production of an atomizing core, the taste is always discussed first, and then the lifespan is discussed. Longevity is built on the premise of good taste. If even the taste is not satisfactory, the producer will not evaluate the life of this core.

The mouthfeel of the atomizing core cannot be evaluated by machine, it can only be inhaled manually. The secret of good taste comes from:

Fever sheet

oil storage cotton

atomizing core structure

When adjusting the smoke, R&D engineers need to find a [balance point] between the above three points and the smoke oil.

Selection of heating element Different materials have different effects. Huachengda's COTTONX future cotton core uses a customized N406 alloy heating element, which is characterized by fast heat conduction and low carbon accumulation.

The design of the heating sheet includes thickness, material, length and width, and circuit design. Very precise requirements are required. Even if its length, width and thickness change by 0.01 mm, it will have a huge change in the taste. Because the thickness affects heat conduction (for example, if the mesh is too wide, the heat will be dispersed), the heat affects the evaporation rate, which in turn affects the taste.

Oil storage cotton The material, density and winding method of cotton are very important factors. The higher the density of cotton, the stronger the oil-holding ability, the slower the oil-conducting speed, and the risk of burning; on the contrary, the lower the density, the faster the oil-conducting speed, but it is prone to oil leakage. After the heating wire is energized, there are six to seven Baidu, and if it is neutralized with smoke oil, the working temperature is only about 200 degrees. Therefore, the speed of oil intake will affect the life and taste. Good cotton should have fast oil conduction speed, strong oil locking ability, and high temperature resistance, so that it is not easy to burn the core.

The atomizing core structure The structure determines the oil inlet speed, COTTONX future cotton core adopts the oil inlet structure around.

[Balance point] There is no fixed answer. It can be said that empiricism is paramount in this subject. Experienced engineers can adjust spontaneously according to the situation on the spot when they are pumping: Is it because the cotton sheet is wrapped in a thick layer, and the oil enters slowly, which affects the aroma? Or, the heating temperature of the heating sheet is not enough, how to adjust the wire diameter and resistance value of the mesh?

Sometimes, the matching cotton sheet is not reasonable enough, so the heating temperature of the mesh sheet needs to be changed to enhance the fragrance; sometimes, the oil absorption effect of the cotton sheet is not good, and the density of the mesh sheet needs to be adjusted. The key is to find the [balance point] between the oil inlet speed and the atomization speed.

Adjusting tobacco is like trying on clothes, you have to tailor your clothes. Different e-liquids have different thicknesses or formulations, and engineers need to provide different solutions to meet customers' taste requirements.

Taste is a very personal feeling. For the same taste, everyone has different evaluations on its aroma, sweetness, humidity, and degree of reduction. Customers come to the scene to adjust the cigarettes. If the customer is not satisfied with the solution provided, Huachengda's R&D engineers will continue to adjust until the customer is satisfied. Once, an old customer who has been cooperating for more than ten years brought more than 20 kinds of e-liquids. Huachengda's engineers provided different atomizing core solutions in one go, and they were blended until three o'clock in the evening. Engineer said:

"Our purpose is to allow customers to settle all matters once they come, so 'life and death' must be called out."

The life of atomizing core

In terms of factors that affect the life of the atomizing core, in terms of external factors, e-liquid accounts for a large proportion. The thickness and chemical impurities of the e-liquid are all related to the life of the atomizing core. The thicker the e-liquid with more impurities, the greater the workload on the atomizing core, just like a person who overeats must be in poor physical condition. People who eat a balanced diet.

Regardless of external factors, as far as the atomizing core itself is concerned, the biggest threat to its life is "carbon accumulation".

Carbon deposits are what remains after atomization. The performance is that the heating wire is black and there is a slurry.

Too much atomization residue will cause the cotton wick to burn, and the taste will be burnt. If the electronic atomizer is working all the time and the temperature is always kept at around 200 degrees, there will be basically no carbon deposition. In the later stage, when there is not much smoke oil left, the oil intake speed of the oil storage cotton will slow down, and the working voltage will not change, the temperature of the heating element will rise, and carbon deposits will be formed rapidly and in large quantities, which will endanger the atomizing core. lifespan.

The principle of carbon deposition is similar to fried food. No matter how low the temperature is, it will not be fried, but when the temperature is high, it will be fried.

Therefore, if you want to prolong the life of the atomizing core, it is best to do it: the atomizing core can guarantee that the sweetness can be extracted at low temperature, so that the taste is very good until the later stage; but at the end, the e-liquid is insufficient, The oil intake becomes less, and the temperature is still rising, so carbon deposits are still inevitable, but the impact will not be too great.
