Principle of electronic cigarette

Electronic cigarette is mainly composed of four parts: tobacco (including nicotine, essence, solvent, propylene glycol, etc.), heating system, power supply and filter tip. Atomized aerosol is produced by heating atomization to produce smog with special odor. Broadly speaking, e-cigarette refers to electronic nicotine delivery system, including e-cigarette, hookah, hookah pen and other forms. In a narrow sense, e-cigarette refers to a portable e-cigarette with a shape similar to that of a cigarette.

Although there are styles or brands of e-cigarettes, general e-cigarettes are mainly composed of cigarette tubes containing nicotine solution, evaporation devices and batteries. The atomizer is powered by a battery rod, which can convert the liquid nicotine in the cigarette bomb into mist, so that the user can have a feeling similar to smoking and realize "swallowing and spitting". It can even add chocolate, mint and other flavors to the cigarette tube according to personal preferences.

The internal structure of the smoke pole uses the same basic components: a lamp, PCBA board, rechargeable battery and various electronic circuits.

Most e-cigarettes use lithium ion and secondary battery power components. Battery life depends on the type and size of the battery, the number of times it is used and the operating environment. And many different types of battery chargers are available, such as socket direct charging, car charging and USB interface charger. Battery is the biggest component of electronic cigarette.

Some e-cigarettes use an electronic air flow sensor to start the heating element. As soon as they inhale, the battery circuit will work. Manual sensing requires the user to press a button and then smoke. Pneumatic is easy to use, the manual circuit is relatively more stable than pneumatic, and the smoke output is also better than pneumatic. With the development of hardware and software, some manufacturers began to develop fully automatic machinery to manufacture electronic cigarettes, and put an end to the use of manual wiring, welding or electronics, so as to achieve higher safety and reliability.

Generally speaking, the cigarette cartridge is the suction nozzle part, and some factories bond the atomizer with the cigarette cartridge or cigarette oil to make a disposable atomizer. The advantage of this is that it can greatly improve the taste and smoke volume of e-cigarettes, and the quality is more stable, because the atomizer is the most vulnerable to failure. Traditional e-cigarettes are a separate atomizer, which will break down in a few days. The factory professionals inject liquid to avoid the problem that too much or too little liquid injection causes the smoke liquid to flow back into the mouth or flow to the battery part to corrode the circuit. The smoke oil storage is also more than that of ordinary smoke bombs, with good sealing performance, so its service time is longer than that of other smoke bombs.

This technology is now owned by very few brands. The structure of the atomizer is a heating component, which is powered by the battery to generate heat, so that the smoke oil beside it volatilizes and forms smoke, so that people can achieve the effect of "swallowing and spitting" when smoking.
