Description

兆赫兹无铅压电雾化元件
技术领域
本发明属于液体雾化及无铅压电技术领域，具体涉及一种工作频率在兆赫兹范围的无铅压电雾化元件。
背景技术
超声波雾化器采用压电陶瓷作为核心元件，通过外加电压驱动压电陶瓷产生高频振动，致使水中微小气泡核迅速生长和崩塌，使水分子团脱离相互作用，达到雾气颗粒直径范畴，产生雾化效果。
现有超声波雾化器均使用锆钛酸铅（PZT）基压电陶瓷制作雾化元件；锆钛酸铅材料中（Pb）元素约占总质量的70％，此类材料在生产、使用及废弃处理时会给生态环境造成严重损害。在超声波雾化器工作时，含铅雾化元件与待雾化液体可直接接触，其中的铅可进入到雾粒中，进而被吸入肺部。
铅是一种对人体危害极大的有毒重金属，铅及其化合物进入机体后将对神经、造血、消化、肾脏、心血管和内分泌等多个系统造成危害，特别是对于妇女和儿童，铅中毒会致畸、危害婴儿发育，破坏儿童神经系统，造成儿童脑组织损伤甚至导致终生残疾。许多国家都已出台相关政策以限制电子产品中铅的使用，如欧盟的RoHS指令要求电子元器件中铅含量不得超过1000ppm。
发明内容
针对上述问题，本发明提供一种兆赫兹无铅压电雾化元件，工作频率介于1~5MHz范围，所述压电雾化元件采用不含铅元素的压电陶瓷材料制成，其中铅含量低于100 ppm，健康环保，可避免含铅压电产品带来的环境污染及健康危害问题。
