Description

一种非可燃性电子雾化香烟
技术领域
本发明涉及一种不含有害焦油，只含烟碱(尼古丁)的非可燃性电子雾化香烟。
背景技术
在当今“吸烟有害健康”已成为常识的情况下，全世界目前仍有10亿人吸烟，而且每年这个数字还在扩大，2003年3月1日世界卫生组织(WHO)通过的第一个国际禁烟协定《烟草控制框架公约》，据WHO提供的数字表明，吸烟每年造成490万人死亡，尽管吸烟可导致严重的呼吸系统疾病和癌症，要吸烟者完全戒烟是一桩极端困难的事。
香烟的有效成份是烟碱(即尼古丁)，吸烟时烟碱随着香烟燃烧时产生的大量焦油雾滴进入肺泡后迅速吸收，烟碱吸收入血后作用于中枢神经系统的受体上，引起类似兴奋剂的“陶醉感”，如吸烟者所经历的头晕目眩或飘飘然的感觉。
烟碱是小分子生物碱，在小剂量下对人体基本无害，而且在血液中的半衰期极短。烟草的有害物质主要是焦油，烟草焦油是由数百种成份组成，其中有数种成份是致癌物。目前证实二次吸烟对不吸烟者的危害更大。
为了寻找只含烟碱而不含有害焦油的香烟代用品，有许多发明是用较纯的烟碱制成诸如“戒烟贴”、“烟碱含嗽水”、“包装在有抛射剂的高压气罐喷雾剂”、“烟碱口香糖”等产品，这些产品虽然没有焦油的危害，但因烟碱吸收缓慢，在血液中不能建立有效的高峰浓度，不能解决需求烟碱“过瘾”的感觉，同时也剥夺了吸烟者已经养成的“抽”“吸”的习惯，因而类似的产品不能真正的作为戒烟用品或香烟代用品。
发明内容
本发明的目的是克服避免了上述缺点，提供一种可模拟吸烟并有吸烟效果，更接近真实的人性化电子雾化香烟。
本发明的特点是，构成香烟的尾端烟嘴处设置的气流传感器连至电路板上用于启动经供液管与贮存烟碱溶液相接的雾化器高频振荡器，高频振荡器接计数电路和显示屏，香烟前端为装有电池并带有发光二极管的端罩。它的基本工作原理是当把烟嘴放在嘴上吸气时，气流传感器输出电信号启动电路，装置在电路板上的高频振荡电路启动向雾化器提供驱动电压，另一组直流渐变信号供给红色发光二极管发出渐变的红光。雾化器上的双压电片发射超声波用于雾化，贮存于塑胶容器中的烟碱溶液经供液管输入雾化器中，经微喷雾化成直径为1-15μm的液滴，其中75％的液滴直径在6μm以下，与进气孔的空气流混合后，能到达细支气管和肺泡中，每次的供液量在3-50μl之间，这样就能在10分钟之内使烟碱在血液中的浓度达到30ng/ml左右，通过液晶显示屏可分别显示出烟碱溶液的消耗量，每天吸烟的次数，对使用者提供警示信息。使用者可通过单向阀补充烟碱溶液。
该装置可逼真的模拟传统的吸烟方式和效果，使吸烟者有吸烟的感觉，而且还无副作用，可实现“吸烟无害健康”。
附图说明
图1为本发明的结构示意图。
图2为本发明的结构框图。
图3为本发明的雾化器结构示意图。
具体实施方式
本发明将烟碱的水、醇溶液微喷雾化，经口吸入肺中吸收，该装置包括壳体、高频发生器、烟碱贮液及容器、微喷雾化器、气流传感器及附件组成的整体。壳体外形是直管状，也可以略有曲线形，还可以是通常的烟嘴形，笔形或其它艺术品形象。壳体一端装有红色塑料帽状装饰物，内置红色发光二极管。电池是可充电锂电池，也可是镍氢电池。高频振荡器是集成电路与功放管组成的三点式电容振荡器、三点式电感振荡器或变压器式振荡电路，频率在35KHz至2.2MHz，电路中带有频率自动微调电路与压电片谐振。液晶显示器，显示该装置的启动次数和贮液量。塑胶容器由硅橡胶制成，不被烟碱浸入的高分子化合物也可使用。注液单向阀是由球状物或锥状物在弹簧压力下密封的。气流传感器是由薄膜状热敏电阻阵列或硅芯片制成的。该装置包含一片粘合了一个环形径向极化压电片的中间有微喷孔阵列的雾化膜片，微喷孔阵列的外周有一圆形波纹环。与该雾化膜片对应的振动膜片上粘合一个圆形单层或多层纵向极化压电片，此振动膜片上开有凹槽或加入垫圈以同雾化膜片组成液体腔。该液体腔边缘开一小孔以连接具有阻尼作用的供液管。该装置是由交流电信号分别驱动两个压电片形成纵向压力波和径向振动波将液体从微喷孔处挤出并雾化。两个压电片各有两个压电信号输入端，压电信号的频率可以不同或一致。两个压电片是同PZT、PMN、PNN、PSN、PMN-PT、PNN-PT、PSN-PT、PZN-PT之一，并具有单层结构或者是不同成分的叠层结构。振动膜片和雾化膜片是由单晶硅片加工成的，也可用耐腐蚀金属或合金制成，如镍片、镍钴合金片、镍钯合金片、镍铬钴铑合金片等。振动膜片和雾化膜片粘合后组成液体腔，液体腔中有由天然纤维或合成纤维制作的供液纤维团。烟碱(尼古丁)溶液是由烟碱、水、乙醇、丙三醇、薄荷醇、烟草香精、抗氧剂、氨水组成。烟碱来自烟草总提取物中的4种烟碱的混合物，也可称为烟草总生物碱，尼古丁是最多的一种，所以用纯尼古丁也可代替烟碱。烟碱(尼古丁)浓度在0.1％-30％之间。该装置可用于经口腔和鼻腔对肺内输送药物或药物前体，提供一种便携式雾化给药装置。
图1是这种电子香烟的结构图。图中的1是红色有机玻璃，2是充电插孔，3是红色发光二极管，4是弹簧，5是锂电池，6是带有旋口18的壳体，7是电路板，8是液晶显示屏，9是信号传输导线，10是塑胶容器，11是连接到塑胶容器口的注液单向阀，12是密封隔板，13是供液管，14是雾化器，15是进气孔，16是气流传感器，17是烟嘴，19是电源开关。
参照图1所示组装各部件成为总体，其中电路板7中的电路设计方框图在图2中标出，其高频振荡器中带有频率自动微调的目的是使压电片始终处于谐振点，雾化器14是由双压电片构成的微喷和雾化两种作用，其结构在图3中示出，其工作原理是利用两个压电片分别驱动组成供液腔的振动膜片和雾化膜片，圆形压电片与振动膜片粘合后组成压电换能器，在液体喷出方向提供高速纵向压力波以使液体经微喷孔处高速喷出。环形压电片与带有微喷孔的雾化膜片粘合组成另一压电换能器。向即将离开微喷孔的液滴提供径向振动波，使液滴进一步破碎。在振动膜片与雾化膜片组成的供液腔中加入一疏松纤维团可改善微喷孔阵列中各微喷孔的能量及液体分配，使之趋于平均。振动膜片和雾化膜片可用单晶硅片或耐腐蚀金属合金制成。改变环形压电片和圆形压电片的驱动电压和频率可获得不同直径的雾滴分布曲线。在微喷孔直径在4-10μm时，雾滴直径在1-15μm的范围内，经调试后充入烟碱溶液即可使用。
图3中的141为环型压电片，142为雾化膜片，143为波纹槽，144为纤维团，145为振动膜片，146为圆形压电片，147为供液腔，148为微喷口，149为压电片引线，1410为供液管，1411为垫圈，1412为凹槽。
烟碱溶液的配制：
用在烟草中提取的95％以上的液态烟碱依次加入水、乙醇、丙三醇、薄荷醇、烟草香精、抗氧剂后再加氨水调整PH值在7.5-11之间，烟碱浓度可在1％-30％之间变动，浓度太高使误差增大，水的加入量可在20％-80％之间变动，乙醇的加入量可在20％-80％之间变动，丙三醇的最高浓度应在45％以下，抗氧剂为丁基化的羟基茴香醚。
