The design of the first generation of electronic cigarettes completely imitates the shape of ordinary real cigarettes in terms of appearance, with yellow cigarette shells and white cigarette bodies. This generation of electronic cigarettes has been popular for several years because their appearance is similar to real cigarettes, and they are accepted by customers at first glance. However, as people increasingly use first generation e-cigarettes, especially foreign customers, they gradually discover many drawbacks of first generation e-cigarettes during use, mainly manifested in atomizers. The atomizer of the first generation electronic cigarette is easily burnt out, and when replacing the cigarette cartridge, it is easy to damage the pointed part of the atomizer. Over time, it will completely wear out, ultimately causing the atomizer to not smoke.
The second generation electronic cigarette is slightly longer than the first generation electronic cigarette, with a diameter of generally 9.25 millimeters. The main feature is that the atomizer has been improved, with a protective cover on the outside of the atomizer. The smoke bomb is inserted into the atomizer, while the first generation electronic cigarette is inserted into the smoke bomb by the atomizer, and the two are exactly the opposite. The most prominent feature of the second-generation electronic cigarette is the merger of the cigarette bomb and the atomizer.
The third-generation electronic cigarette uses a disposable atomizer cartridge, which is equivalent to a disposable atomizer, solving previous problems, greatly improving quality, and replacing the appearance and raw materials.
Although e-cigarettes come in different styles or brands, they generally consist of three parts: a cigarette tube containing nicotine solution, an evaporation device, and a battery. The atomizer is powered by a battery rod and can convert the liquid nicotine in the cigarette bomb into mist, giving the user a feeling similar to smoking and achieving "puffing in the clouds". It can even add various flavored spices such as chocolate and mint to the tobacco tube according to personal preferences.
Cigarette rod
The internal structure of the cigarette pole uses the same basic components: a light PCBA board, rechargeable batteries, and various electronic circuits.
Most e-cigarettes use lithium-ion and secondary battery power components. The battery life depends on the type and size of the battery, the frequency of use, and the operating environment. And there are many different types of battery chargers to choose from, such as socket direct charging, car charging, and USB interface chargers. Batteries are the largest component of e-cigarettes.
Some e-cigarettes use an electronic airflow sensor to activate the heating element, which can cause the battery circuit to operate upon inhalation. The manual sensing requires the user to press a button and then smoke. The use of pneumatic is convenient, and the manual circuit is relatively stable compared to pneumatic, and the smoke output is also better than pneumatic. With the development of hardware and software, some manufacturers have begun to develop fully automated mechanical manufacturing of electronic cigarettes, eliminating the use of manual wiring, welding, or electronics to achieve higher safety and reliability.
Atomizer
Generally speaking, the smoke cartridge is the suction nozzle part, while some factories bond the atomizer with the smoke cartridge or oil to make a disposable atomizer according to customer needs. The advantage of doing so is that it can greatly improve the taste and smoke volume of e-cigarettes, while maintaining a more stable quality, as the atomizer is the easiest to break. Traditional e-cigarettes are a separate atomizer that breaks down in just a few days. Injecting liquid by professional personnel in the factory avoids the possibility of excessive or insufficient self injection, which can cause smoke to flow back into the mouth or into the battery
