1. A battery: the same basic components are used for the internal construction of the battery: a lamp PCBA board, a rechargeable battery and an electronic circuit.
2. An atomizer: the atomizer is a heating element, and the battery supplies power to generate heat, so that the tobacco tar beside the atomizer volatilizes to form smoke, and the atomizer can achieve the effects of cloud swallowing and fog spraying when people inhale. The quality of the product mainly depends on materials, heating wires and processes.
3. A smoke cartridge: generally, the cartridge is a mouthpiece portion and some factories adhere the atomizer and cartridge together to make a disposable atomizer according to the customer's needs.
