Frequently Asked Questions
- What is an e-cigarette module?
An e-cigarette module is one of the core components of an e-cigarette device. Our module (HCP) typically includes a capacitor-based battery, electronic control chip, circuit board, and other key components used to control and adjust the performance and functionality of the e-cigarette. The e-cigarette module is designed to be modular, making it easy to install into e-cigarette devices and greatly simplifying the assembly process.
- How is the microphone battery of an e-cigarette soldered?
Traditionally, soldering is required to connect the battery, atomizer, and microphone of an e-cigarette. However, our module comes with a built-in battery, allowing for direct connection of the atomizer to the casing using a top pin. This simplifies the assembly process and reduces labor costs.
- How does the microphone of an e-cigarette work with the chip?
The microphone (mouthpiece) of an e-cigarette typically works in conjunction with the chip to control and monitor the smoking operation. The simplified steps are as follows: inhalation detection – chip response – temperature control – current control – LED indication – battery management.
