E-cigarette supply chain Process Introduction (2)

Three. Electronic components

Electronic components include batteries, head, solution boards, etc., and further, include display screens, chips, PCB boards, fuses, and thermal sensors
Resistance and so on.


1. Batteries
The battery determines the length of the service life of e-cigarettes, and how long e-cigarettes can last depends on the battery capacity. E-cigarette batteries are soft
Bag and hard shell, cylinder and square, the combination of cylindrical soft pack battery, square soft pack battery, cylindrical steel shell battery and other types.
Electronic Cigarette battery cathode materials include three kinds: pure cobalt series, ternary series, and the two mixed series.

The mainstream material in the market is pure cobalt, which has the advantages of high discharge voltage platform, large rate discharge, high energy density, etc. The electric voltage platform of pure cobalt is between 3.4-3.9V, and the term-based discharge platform is mainly 3.6-3.7V. The discharge rate also has higher requirements, with
Discharge rates of 8-10C, such as the 13350 and 13400 models, are required to achieve 3A sustained discharge capacity.
2. Mi head, solution board
Imidou is the current mainstream starting element of electronic cigarettes, electronic cigarettes can simulate the traditional smoking process, it is inseparable from the credit of imidou.

At present, the e-cigarette head generally refers to the combination of capacitive head + chip, which is installed on the scheme board, connected to the heating wire and battery through the line, and plays the role of intelligent startup, charge and discharge management, status indication, and output power management. In type, the midhead has a slave electret
The development trend of the body to silicon wheat.
The solution board is to integrate various electronic components on the PCB board, such as Mi head, display screen, MCU, Mi head, fuse, MOS
Tubes, thermistors, etc. Board production process has welding line, SMT and so on.

3. Display, fuse, thermistor, etc
The display screen was first applied to tobacco products, used to display power, electricity, and even to develop interactive gameplay, and later on a small number of change-type products have applications, the current application hotspot is a one-time small cigarette, with a certain head brand explosion as a starting point, the industry has followed
It is mainly used to display the amount of oil and electricity.

It is reported that the fuse is about to play, the United States market has mandatory requirements, the purpose is to prevent electronic cigarettes in the use of short circuit explosion and other risks. Some foreigners like to open Disposable Electronic Cigarettes, refill the oil, charge, the refill process will need a safety
The dangerous silk has come to protect the foreigners.

Four, structural components
The structural components include housing, oil tank, battery support, sealing silicone, spring thimble, magnet and other components.

1. Shell (plastic, aluminum)
No matter what kind of e-cigarette, or HNB heater, can not be separated from the shell. As the saying goes, man by clothes, products by the shell. consumption
Whether you are chosen or not, how good you look plays a very important role.

The shell material of different products will have some differences. For example, Disposable Electronic cigarettes are mainly plastic shells, and the material is PC, ABS, and work
Art is common with ordinary injection molding + spray paint (gradual color/monochrome), but also flow, two-color injection molding, sprinkling, free spraying and so on.
Of course, disposable electronic cigarettes also have the solution of using aluminum alloy shell + feel paint, and the change-bomb type in order to provide better feel, more
It is made of aluminum alloy, if it is like a cigarette product, in order to increase the feel, it will also use a shell such as zinc alloy.



Of course, the shell is not a single material, can be combined to use, good looking on the line. For example, in the United Kingdom, a brand of crystal disposable electronic cigarettes is the use of PC transparent shell to create a crystal clear texture, which uses a gradual anodized aluminum alloy tube
Add rich colors.
In the surface treatment process, spray oil (spray paint) is more common, in addition to direct stickers, pasting, IML, anodic oxygen
Melt and wait.

2. Plastic parts such as oil tanks, battery brackets, and bases
In addition to the outer shell, the electric smoke also has oil silo, electric cell support, base and other parts. The materials include PCTG (commonly used in oil silo), PC/ABS, PEEK (commonly used in HNB heater), PBT, PP, etc. Basically, they are injection molded parts. Alloys are rare.

3. Sealing silicone
The use of sealed silicone for electronic cigarettes is mainly to prevent oil leakage, while making the structure of electronic cigarettes more compact and compact. Application parts such as suction nozzle
Sleeve, airway plug, oil bin base, mi head base, cartridge sealing ring of bomb changing products, sealing ring of large smoke atomizing core, etc.

4. Spring thimble, magnet
Spring thimble, also known as Pogo pin, spring pin connector, charging pin connector, probe connector, etc., mainly used in bomb changers, CBD atomizers, large smoke products, HNB heater, This is because these types of atomization structures are separated from the cell pole
Therefore, a thimble is needed to connect, and is generally used with magnets.

5. Equipment
Equipment throughout the entire industry chain, as long as there is a processing place, there is the existence of equipment, such as oil filling machine, box filling machine, laminating machine, laser equipment, CCD optical machine, automated testing machine, automated assembly, etc., there are common models in the market, but also non-standard custom open
The model of the hair.

6. Supporting services
Supporting services, mainly refers to logistics, financial account opening, agent handling, testing and certification and so on.

Sum up
The above is about the combing of the e-cigarette supply chain, you can see that behind the small e-cigarette, is a large and complex industrial system.
