Description

一种电子雾化器用曲形透明玻璃加热体及其制作方法 技术领域
本发明涉及电子雾化器用加热体，特别是一种电子雾化器用曲形透明玻璃加热体及其制作方法。
背景技术
传统的电子雾化器用于烟丝和烟膏的发热元件有两种：一种是发热丝，发热丝直接安装在金属体的外侧，通过热传递的方式加热，发热丝易于与外界的空气直接接触，使得发热丝在加热时，裸露在空气中，极易被氧化，导致使用寿命短。另外一种发热元件是陶瓷杯状发热体，该发热体结构是由两层陶瓷和一组发热线路组成，该种发热体表面为纯白色，安装或清洗时与其它物体接触(特别是金属)易出现划痕、脏污等现象，不易清洗，给人感觉不安全、不卫生。
此外，现有技术还有采用在玻璃上印刷银钯电极以形成半导体发热膜的方案，主要存在以下几点缺陷：
1.电极层表面附着力差，易脱落，不可多次碰刮，严重影响使用寿命；
2.对玻璃材质要求高，必须是纯度非常高的石英玻璃方可进行印刷，这使得此技术成本无法降低，限制了技术的大规模推广使用；
3.银钯电极层耐高温效果差，工作温度超过350℃时银钯层会起泡，使加热体失效；
4.半导体发热膜不稳定，功率存在衰减问题。
