The refillable electronic cigarette was first invented by Chinese pharmacist Hon Lik in 2003. Electronic cigarettes became available for the public in 2005. The first company which launched the concept of electronic cigarettes was ‘Ruyan’. Since then, electronic cigarettes have skyrocketed in sales, and most smokers start by purchasing a refillable electronic cigarette kit, and then move onto buying supplies like e juice.
A refillable electronic cigarette is made up of three essential parts. The first part of refillable electronic cigarettes is their cartridge. A cartridge is a mouthpiece for its users. It is a cylindrical type container which contains the e juice, which is responsible for the electronic cigarettes flavors. This cartridge is refillable for e juice. So once your cartridge became empty, it can be easily refilled, hence the reason electronic cigarettes are conveniently called refillable electronic cigarettes often.
The other portion of electronic cigarettes are the atomizers. Atomizer is nothing but a heater for the cigarette or of e juice. Of course, there is no need for fire in the case of electronic cigarettes. You can easily switch on the cigarette and it will perform like a tobacco smoke, turning the e juice into a vapor. This working occurs due to the presence of heater, or the atomizer. It works in the middle of cartridge and battery of a refillable electronic cigarette.
