Description

一种常温超声雾化电子烟
技术领域：
本发明涉及电子烟技术领域，特别是指一种常温超声雾化电子烟。
背景技术
传统的抽烟方法是用火燃烧烟草产生烟雾供人们吸取。但是，通过烟草燃烧的方法所产生的烟雾，会产生2000多种有害物质，会对人体产生不良影响，且长期吸取这种方式产生的烟雾，影响会越来越严重。据世界卫生组织数据统计，全球目前有13亿烟民，每年约有500万人因吸烟而死亡，烟草已成为继高血压之后的第二号“杀手”，如果不加以控制，到2020年每年吸烟致死人数有可能增加一倍。
对于烟民来说戒烟是一件非常困难的事情，电子烟的出现在一定程度上解决了上述问题，电子烟是一种模仿卷烟的电子产品，有着与卷烟相似的外观、烟雾、味道和感觉，如专利申请号“200420031182.0”的中国专利公开了一种电子仿真烟，包括壳体及吸嘴，壳体的外壁上开有进气孔，壳体内依次设有电子线路板、常压腔、传感器、气液分离器、雾化器、供液瓶；其中电子线路板由电子开关电路及高频发生器组成；在传感器的一侧开有传感器气流通道，传感器内设有负压腔；雾化器与供液瓶相接触，在雾化器的内部设有雾化腔；供液瓶的一侧与壳体之间设有锁定供液瓶的挡圈，供液瓶的另一侧开有雾汽通道；进气孔、常压腔、气液分离器、雾化器、雾汽通道、导气孔、吸嘴依次相连通。上述专利公开的电子烟以及其他类似产品的优点在于：
1、安全：不燃烧，无明火，降低火灾隐患。
2、环保：不燃烧，不会产生烟灰，没有烟蒂。
3、方便：携带方便，想抽就抽，不抽则放在一边。
4、能过一定烟瘾，不改变抽烟者的习惯，所以非常畅销。
上述已有的电子烟消耗的不是烟草，而是电子烟油，又名电子烟液，是配合电子烟使用的电子雾化液。电子烟油的主要成分是食用级或者医药级别的甘油，以及烟草专用香精。某些电子烟油中也含有烟碱成分，主要是为了其口感更加贴近香烟。在上述电子烟的使用过程中，将烟油注入电子烟中，通过电子烟雾化器使其雾化，产生如香烟一样的雾气。其中的雾化器实际就是一个加热元器件，通过电池供电发热，使其旁边的烟油挥发，形成烟雾。目前市售的电子烟都是这种采用加热方式的雾化器，将烟油加热，使其雾化。
上述已经公开的电子烟以及其他类似产品缺点在于烟油变质，液态的烟油在加热的过程中，承受的温度会高达300℃，如此高温会使烟油产生一定的质变，易产生焦味，不仅影响口感、降低烟油的品质，而且生成的烟雾中也难免会存在燃烧产生的有害物质，由于温度高，因此对电池的消耗也大，过高的温度还会导致电子烟嘴的温度过高，导致电子烟烫手，影响用户体验感受的同时也损害电子烟的使用寿命。
发明内容
为了解决以上问题，本发明提供了一种常温超声雾化电子烟，通过施加交变电压，驱动金属膜片起振，产生超声波使烟油雾化，消除了烟油因高温而降低品质的问题。
一种常温超声雾化电子烟，其特征在于：包括壳体9，壳体9内部设置有电源8、控制器11、超声波雾化器2，电源8、控制器11、超声波雾化器2依次连接，超声波雾化器2一侧设置有吸嘴1，超声波雾化器2中包括超声波换能元件和烟油6，超声波换能元件可产生频率高于20000赫兹的超声波，采用该频率的超声波对烟油6进行雾化。
进一步地，电源8为锂离子电池。
进一步地，壳体中部设置有与控制器11连接的开关7，以便于用户对电子烟进行控制。
进一步地，开关7是外置的按钮开关，或是内置的负压感应开关。
进一步地，在电源8底部设置有指示灯10。
进一步地，控制器11为控制线路板结构。
进一步地，所述超声波换能元件为两片相对设置的超声波雾化片一3、超声波雾化片二12，超声波雾化片一3、超声波雾化片二12之间设置有密封罩4，超声波雾化片一3、超声波雾化片二12、密封罩4形成容纳烟油6的容纳空腔；吸油棉棒5设置在所述密封空腔中部，其两端分别抵靠在超声波雾化片一3、超声波雾化片二12的中部。
进一步地，密封罩4采用圆形玻璃筒结构，圆形玻璃筒的两个端面通过法兰分别与两片圆形的超声波雾化片一3、超声波雾化片二12连接。
进一步地，超声波雾化片一3、超声波雾化片二12均包括压电陶瓷环14与金属膜片19，结构为环形的压电陶瓷环14设置在金属膜片19中部，在环形的压电陶瓷环14内部的金属膜片19上开设有多个气孔21，在环形的压电陶瓷环14背离金属膜片19的一侧设置有镀银层15，在镀银层15上设置有镀银层电极焊点一17，在金属膜片19外缘设置有镀银层电极焊点二18，镀银层电极焊点一17、镀银层电极焊点二18分别与控制器11连接并通过控制器11对镀银层电极焊点一17、镀银层电极焊点二18施加交变电压，压电陶瓷环14的厚度会随着电压的改变而改变，当施加交变电压的时候，压电陶瓷环14会产生微小的振动，从而带动与其紧密固联的金属膜片19振动，从而产生超声波对烟油6进行雾化，雾化烟油20通过多个气孔21渗出进入气路通道。
进一步地，气孔21直径为4~7um。
该常温超声雾化电子烟结构简单，安装、操作简便易行，利用超声波雾化片产生超声波并使得烟油分子雾化，无需燃烧烘烤即可产生烟雾，有效保持口感，避免有害物质的产生，使用安全环保，用户体验更佳，使用寿命更长。

具体实施方式：
下面结合说明书附图对本发明的常温超声雾化电子烟做进一步详细的说明。
如图1所示，本发明常温超声雾化电子烟包括壳体9，壳体9可采用塑料、玻璃与金属等的结构件，固定电子烟内置的各种组成部分。壳体9内部设置有电源8、控制器11、超声波雾化器2，电源8、控制器11、超声波雾化器2依次连接，超声波雾化器2一侧设置有吸嘴1，超声波雾化器2中包括超声波换能元件和烟油6。进一步地，电源8为锂离子电池，提供电子烟进行正常工作所需要的电能，便于携带，可以反复充电使用。
如图2所示，为本发明常温超声雾化电子烟的工作原理示意图，本发明电子烟超声波雾化器2采用超声波进行雾化的原理为：
超声波的方向性好，穿透能力强，易于获得较集中的声能，在液体中传播距离远，可用于测距、测速、清洗、焊接、碎石、杀菌消毒等。在医学、军事、工业、农业上有很多的应用。超声波因其频率下限大于人的听觉上限而得名。超声波在媒质中的反射、折射、衍射、散射等传播规律，与可听声波的规律没有本质上的区别。但是超声波的波长很短，只有几厘米，甚至千分之几毫米。与可听声波比较，超声波具有许多奇异特性，其中之一就是：空化作用。超声波作用于液体时可产生大量小气泡。一个原因是液体内局部出现拉应力而形成负压，压强的降低使原来溶于液体的气体过饱和，而从液体逸出，成为小气泡。另一原因是强大的拉应力把液体“撕开”成一空洞，称为空化。空洞内为液体蒸气或溶于液体的另一种气体，甚至可能是真空。因空化作用形成的小气泡会随周围介质的振动而不断运动、长大或突然破灭。破灭时周围液体突然冲入气泡而产生高压，同时产生激波。与空化作用相伴随的内摩擦可形成电荷，并在气泡内因放电而产生发光现象。在液体中进行超声处理的技术大多与空化作用有关。本发明利用该原理使电子烟的烟油雾化。此外超声波也存在热效应，由于超声波相对于普通声波具有频率高、能量大的特点，被介质吸收时能产生热效应，但相对于采用电热丝直接加热的方式，其温度不高，耗散也快，因而不会带来烟油的变质，而且适度的温度，可以是雾气具有更逼真的口感。
通过不断研究对比得出，频率高于20000赫兹的超声波对烟油的雾化效果最好，用户的吸烟口感最佳，因此本发明的电子烟中超声波雾化器2中超声波换能元件可产生一种频率高于20000赫兹的超声波，采用该频率的声波对超声波雾化器2中烟油6进行雾化。
进一步地，壳体中部设置有与控制器11连接的开关7，以便于用户对电子烟进行控制。开关7的作用是触发电子烟出雾，开关7可以是外置的按钮开关，也可以是内置的负压感应开关（当用户抽吸电子烟的时候，抽吸产生的空气负压触发开关闭合）。当开关闭合，将触发控制线路板的运行，并激活输出功率，是电子烟工作。
进一步地，在电源8底部设置有指示灯10，当电子烟处在工作状态中的时候，控制器11的线路板的逻辑控制单元导通LED的输出电路，使LED发光。通过指示灯10的发光，显示电子烟的工作状态，使用户在使用过程中，具有更丰富的交互体验，比如采用红色LED指示灯，它发光就模拟烟头燃烧的发光效果。
在一种优选实施方式中，控制器11为控制线路板结构，其采用微处理器作为中央逻辑处理单元，读入来自锂离子电池以及开关7、传感器件的信号，进行内部的逻辑运算后，输出相应的控制信号，驱动内置的功能模块，实现电子烟的各种特定功能。控制器11的主要作用是实现电子烟的逻辑控制，接收开关7的触发信号，或感应人抽吸的负压开关的触发信号，锂电池充放电管理，电压稳定与转换，超声波电压电流驱动，光电外观显示等。
在本发明的一种最佳实施方式中，如图1、4所示，超声波雾化器2中超声波换能元件为两片相对设置的超声波雾化片一3、超声波雾化片二12，超声波雾化片一3、超声波雾化片二12之间设置有密封罩4，超声波雾化片一3、超声波雾化片二12、密封罩4形成容纳烟油6的容纳空腔，吸油棉棒5设置在所述密封空腔中部，其两端分别抵靠在超声波雾化片一3、超声波雾化片二12的中部。
如图4所示，吸油棉棒5的作用是将烟油6稳定的输送到超声波雾化片一3、超声波雾化片二12的表面。由于烟油6是液体，呈现流动状态，当电子烟的水平姿态改变，烟油6水平表面将相应变化，并且随着烟油6的消耗，水平表面逐渐降低，这将影响到烟油与超声波雾化片一3/超声波雾化片二12的接触面积，从而影响雾化效果。吸油棉棒5可保证烟油6无论在什么情况下，如当电子烟呈现倾斜状态的时候，吸油棉棒5都能均匀地传递到超声波雾化片一3/超声波雾化片二12的表面。
进一步地，密封罩4采用圆形玻璃筒结构，便于观察烟油的剩余容量，圆形玻璃筒的两个端面通过法兰分别与两片圆形的超声波雾化片一3、超声波雾化片二12连接。在法兰与玻璃筒，法兰与超声波雾化片一3、超声波雾化片二12之间，分别采用O型橡胶圈或其它密封材料进行密封。密封罩4的作用是将烟油密封在一个封闭的容器中，对于可以反复使用的型号，还可以拆开密封罩，以便注入新的烟油。
超声波雾化片一3、超声波雾化片二12在控制器11的操控下可产生频率高于20000赫兹的声波，从而对烟油6进行雾化，雾化的烟油通过超声波雾化片一3、超声波雾化片二12中部的气孔21渗出并通过气路通道到达吸嘴1处。
进一步地，如图3所示，超声波雾化片一3、超声波雾化片二12均包括压电陶瓷环14与金属膜片19，结构为环形的压电陶瓷环14设置在金属膜片19中部，在环形的压电陶瓷环14内部的金属膜片19上开设有多个气孔21，如图3所示，金属膜片19中间区域的气孔21一般采用激光加工，可以小到4~7um，因此从气孔21中扩散处理的雾化烟油20的雾滴的直径小于7um。
如图3所示，在环形的压电陶瓷环14背离金属膜片19的一侧设置有镀银层15，在镀银层15上设置有镀银层电极焊点一17，在金属膜片19外缘设置有镀银层电极焊点二18，镀银层电极焊点一17、镀银层电极焊点二18分别与控制器11连接并通过控制器11对二者施加交变电压，压电陶瓷环14的厚度会随着电压的改变而改变，因此当给它施加一个交变电压的时候，它就会产生微小的振动，从而带动与它紧密固联的金属膜片19振动，从而产生超声波对烟油6进行雾化，雾化烟油20通过多个气孔21渗出进入气路通道。进一步地，这种高频振动产生超声波从而将金属膜片表面的烟油液体雾化。雾化的烟油就会从金属膜片中间的微孔散发出来，形成持续的烟雾。
应当指出的是，上述内容只是本发明的最佳实施方式的列举，其中未尽详细描述的部分，应该理解为用本技术领域的一般方式予以实施。同时，对于本领域的一般技术人员来说，在不偏离本发明的精神范畴内对本发明所做的等效变换和修饰，都将落入本发明的权利要求的保护范围之内。
