Whether it's a disposable electronic cigarette or a cartridge-replaceable electronic cigarette, both consist of two main components: the atomization chamber and the battery rod. In this article, we will dissect each part separately.
1. Atomization Chamber
The atomization chamber of an electronic cigarette, as the name suggests, is the component that vaporizes the e-liquid into an aerosol. Its primary structure includes the mouthpiece, atomizer core, oil cup, base, sealing silicone, and connectors.
烟嘴:材质常见是PCTG、PC/ABS、陶瓷,其中陶瓷多用于CBD雾化器上,为契合嘴巴吸食,多设计成扁圆形状。
atomizer core:由发热丝+导油材质组成,发热丝又分绕丝、蚀刻网片、厚膜印刷金属浆料等,导油材质有棉和多孔陶瓷,也因此有陶瓷芯、棉芯之分,陶瓷芯主打口感细腻,棉芯主打爆发力强,口感还原度高。
储油棉:专用于存储烟油的部件,是纤维经过热熔抱合工艺制备的,具有工艺成熟、成本低、储油性好等优点,在一次性电子烟上应用较为普遍。
油杯:材质常见是PCTG和玻璃,以PCTG最为常见,而玻璃多用于CBD雾化器;性能要求是耐化学性、耐高温性。透明油仓正在快速发展,因为它满足了消费者进度可视化的需求。
其他部件:底座通常是PC/ABS材质,配合密封硅胶,来封住烟油不漏;连接器根据电子烟种类有所不同,如果是一次性电子烟,会直接两条线与方案板焊接,如果是换弹式电子烟,则常见是采用弹簧顶针。
2. Battery Rod
The battery rod of an electronic cigarette primarily provides power and features functions such as switch activation, power control, and temperature regulation. Its structure includes the battery, PCBA board with microphone, body casing, indicator light, charging port, and connectors.
电池:常见是软包锂电池,尺寸根据电子烟种类来定,高能量密度、环保是发展趋势。其中,随着环保趋势的发展,电容式电池开始在电子烟上有应用,结合可拆卸式设计,电子烟被废弃后电池回收更具有可行性。
PCBA:方案板集成了电子烟开关、电源管理、开关启动、功率调节、控温等功能,当下最为热门的是带屏方案开发,朝着智能化方向发展,由此对芯片等电子元件提出了更高的要求。
咪头:电子烟的开关元件,又叫气流传感器,可感应气流的变化,从而引起电变化,最终启停电子烟。目前的趋势是传统驻极体电容咪往着硅麦方向发展,变得更灵敏,三防性能更好。
显示屏:出货相对较多的是小尺寸数码管,仅显示油量、电量,优点是成本低,设计简单,而TFT屏、柔性屏(特别是星空屏)等,相对成本更高,但因其酷炫的显示效果而备受行业关注。
机身外壳:一次性电子烟的外壳多是塑胶外壳,材质为PC、PC/ABS,换弹式的一般是铝合金,个别会用锌合金。外壳的外观工艺常见是喷涂手感漆、渐变色等。环保材质如PLA、纸管的应用还需要进一步优化。
总的来说,电子烟的品类及结构受到政策、市场喜好、技术工艺等因素影响,而更紧凑、更智能、环保可持续是发展方向及趋势。
