Der innere Aufbau von E-Zigaretten in Kastenform

The internal structure of box-type e-cigarettes mainly revolves around three core functions: electric power drive, e-liquid atomization, and user interaction. Its specific composition is as follows:

First, batteries and power supply modules

Batterie

Box-type e-cigarettes usually use rechargeable lithium batteries (such as 18650 and 21700 models), and some devices are equipped with non-detachable batteries. The battery supplies power to the atomizer, supporting long-term use of the device. Some high-end devices support voltage or power regulation, allowing users to adjust the output power according to their needs.

Circuit protection

The battery management module integrates functions such as overcharge protection, overdischarge protection, and short-circuit protection to ensure safe use. Some devices also feature intelligent power management functions, such as wide-voltage charging and constant voltage output control, to extend battery life.

Second, atomizer and e-liquid module

Atomization core

The atomization core is the core heating element of the box-type electronic cigarette, composed of heating wire and oil-conducting material. The heating wire is usually made of materials such as nickel-chromium alloy, titanium or ceramic, while the oil-conducting material includes cotton or porous ceramic. Ceramic cores are known for their delicate texture, while cotton cores offer strong explosive power and high texture fidelity.

Oil storage tank

The oil storage bin is used for storing e-liquid and is mostly made of glass or PCTG plastic. Some of the equipment adopts a transparent oil tank design, which is convenient for users to observe the remaining amount of e-liquid. The oil storage tank and the atomizing core are connected through oil-guiding cotton or ceramic structures to ensure a continuous supply of e-liquid.

Components of e-liquid

E-liquid is mainly composed of propylene glycol (PG), vegetable glycerin (VG), food-grade flavoring and nicotine (optional). The types of nicotine include free base nicotine and nicotine salts, the latter of which has a smoother taste.

Third, the interaction and control module

Switches and Sensors

Box-type e-cigarettes usually adopt air flow sensing switches (microphones), which start the device by sensing changes in air flow. Some devices are also equipped with physical buttons, supporting manual on/off or power adjustment. The microphone head integrates an airflow sensor recognition circuit inside, featuring strong anti-interference ability and sensitive response.

Indicator lights and display screens

The equipment casing is usually equipped with indicator lights to display information such as battery level and working status. Some high-end devices adopt small-sized digital tubes or TFT screens, supporting real-time display of information such as fuel level, battery power and power.

Shell and Interface

The shell materials are mostly aluminum alloy, stainless steel or resin, and the design focuses on portability and hand feel. The bottom or side of the device is equipped with a charging interface (such as Micro USB or Type-C), and some devices support the fast charging function. The atomizer is connected to the battery rod by thread or magnetic attraction, which is convenient for replacement.

Fourth, other auxiliary components

Sealing structure

The oil storage tank and the atomizer are sealed by sealing silicone or O-rings to prevent the leakage of e-liquid. Some of the equipment adopts a double sealing design to enhance the leak-proof performance.

Heat dissipation and insulation

Insulating rings or ceramic bases are usually wrapped around the heating wire to prevent short circuits. Some devices add heat sinks between the battery and the circuit board to ensure stability during long-term use.
