进一步地，该金属层212具体包括第一电极2122和第二电极2123，第一电极2122设置在压电基底211靠近供液通道13一侧的第一表面上，第二电极2123设置在与第一表面相背的第二表面上，进液部2121设置在第一电极2122上。图3及图4是本发明的两个实施例中的雾化芯，本实施例中，第一表面指图示压电基底211的上表面，第二表面指压电基底211的下表面，第一表面与第二表面的位置相背，进液部2121具体设置在位于压电基底211第一表面上方第一电极2122上，进液部2121的位置可以是处于第一电极2122的任意位置上，进液部2121实际是压电基底211上没有镀电极的裸露的区域，可以理解为在第一电极2122上开设的作为液体的雾化区域，目的是为了确保液体的润湿性更好以及阻碍液体的运动。具体的，压电基底211上、下表面，即压电基底211的第一表面和第二表面的金属导电层施加的交流电信号是随时间变化，电流方向发生变化的信号，包含但不限于正弦波、方波、锯齿波以及它们的射频信号。

进一步地，雾化壳体1内设有芯片支架14，雾化芯片21可安装在芯片支架14上，用于提供支撑力给雾化芯片21，以相对限定雾化芯片21的位置。雾化芯片21的位置可以是水平、垂直以及其它任意角度，雾化芯片21的位置与芯片支架14的设置位置有关，雾化芯片21的设置位置也与雾化液的供液方式有关。
如图1所示，在本实施例中，雾化芯片21上的雾化液的供液方式为滴液式，沿出液孔12竖直向下延伸设置有导流板，以形成供液通道13，供液通道13对准雾化芯片21的进液部2121，保证雾化液能顺利进入到进液部2121上，雾化液经供液通道13在重力作用下滴落到进液部2121上进行雾化。
芯片支架14水平设置在储液腔11下方，可将雾化芯片21放置在芯片支架14上，用于对雾化芯片21起支撑作用，故雾化芯片21水平设置在储液腔11下方，雾化芯片21的进液部2121表面与供液通道13内雾化液的出液方向相垂直，通过自由落体作用将所述供液通道13内的雾化液滴落至所述进液部2121中。芯片支架14安装在雾化壳体1的底壁内侧，其一端固定在雾化壳体1左右其中一侧内壁面上，另一端与相对一侧的内壁面留有间隙，以便设置进气通道15。该雾化器还包括底座3和吸嘴4，底座3用于承载雾化组件2，底座3与雾化壳体1底部相连，雾化壳体1底部开设有开口，底座3侧壁上开设有进气孔31，以让外界空气进入。该开口与进气孔31之间连通，形成进气通道15。吸嘴4设置在雾化壳体1顶端，且穿出于雾化壳体1顶壁，用于输出气溶胶以供用户吸食；进气孔31连通至雾化壳体1内的进气通道15，进气通道15连通气流通道16至雾化壳体1顶端的吸嘴4。储液腔11位于雾化壳体1内，储液腔11与雾化壳体1壁面之间留有导通的气流通道16，该气流通道16与进气通道15相连通，经雾化芯片21雾化后得到的气溶胶，气流通道16连通至设置在雾化壳体1顶端的吸嘴4，当使用者吸食时，气溶胶在压差的作用下在气流通道16中流通至吸嘴4进入使用者口中。雾化壳体1底壁连接有可导电的弹簧垫片32，用于实现雾化器与电源组件5之间电连接；具体的，弹簧垫片32设置在底座3内，弹簧垫片32第一端与雾化壳体1底壁连接，弹簧垫片32第二端与电源组件5连接，以实现电源组件5对雾化器进行供电。
进一步地，如图2所示，在另一些实施例中，雾化芯片21上的雾化液的供液方式可以为引流式。
芯片支架14竖直设置在雾化壳体1内，且与雾化壳体1侧壁相平行，固定在与储液腔11位置相对一侧内壁面上，芯片支架14固定在该内壁面上，用于相对限制雾化芯片21的位置，雾化芯片21可安装在芯片支架14上，由于受该实施例中的雾化芯片21安装限制，需要设置导油件将储液腔11内的雾化液引流至雾化芯片21内进行雾化，因此，雾化组件2还包括多孔导油块22，储液腔11下方设有隔板，隔板延伸设置至多孔导油块22处，以形成供液通道13，多孔导油块22设置在供液通道13与雾化芯片21之间，具体的，该多孔导油块22设置在供液通道13与进液部2121之间，通过毛细力作用将所述供液通道13内的雾化液导向至所述进液部2121中，以实现精准供液。具体的，该多孔导油块22可以为棉芯、纤维、纸条、陶瓷、多孔玻璃等导油材质中的任意一种。
雾化壳体1底部可与底座3连接，雾化壳体1底部开设有开口，底座3上开设有进气孔31，以让外界空气进入；该开口与进气孔31之间连通，形成进气通道15。储液腔11位于雾化壳体1内，储液腔11与雾化壳体1壁面之间留有导通的气流通道16，该气流通道16与进气通道15相连通，经雾化芯片21雾化后得到的气溶胶，气流通道16连通至设置在雾化器顶端的吸嘴4，吸嘴4穿出于雾化壳体1，用于输出气溶胶以供用户吸食，当用户吸食时，气溶胶在压差的作用下在气流通道16中流通至吸嘴4进入用户口中。雾化器连接有可导电的弹簧垫片32，用于实现雾化器与电源组件5之间电连接；具体的，弹簧垫片32设置在底座3下方，弹簧垫片32第一端与底座3连接，弹簧垫片32第二端与电源组件5连接，以实现电源组件5对雾化器进行供电。
可理解地，雾化芯片21上的雾化液的供液方式不仅限于上述的滴液式和引流式，还可以采用其它可实现的供液方式。
如图5所示，本发明还构造了一种电子雾化装置，包括电源组件5及上述的雾化器，电源组件5与雾化器电连接并给雾化器供电。
进一步地，底座3上设有可导电的弹簧垫片32，雾化器的雾化组件2通过弹簧垫片32与电源组件5电连接。具体的，弹簧垫片32设置在底座3下方，弹簧垫片32第一端与底座3连接，弹簧垫片32第二端与电源组件5连接，以实现电源组件5对雾化器进行供电。
本发明工作原理如下：
在一定厚度的压电基底211第一表面和第二表面镀金属层212，以铌酸锂作为压电基底211的压电材料，形成无叉指换能器的铌酸锂基底声波雾化芯片21，其谐振频率受基底厚度控制。当在压电基底211第一表面、第二表面的金属层212施加交流电信号后，由于铌酸锂材料的逆压电效应，即电能转换为机械能，在整个压电基底211中产生机械振动，即高频体声波；其中，交流电信号频率根据声波雾化芯片21谐振频率确定。声波作用于压电基底211上表面进液部2121处的液体时，基底表面高达108m/s的振动加速度在液体表面形成毛细波，即表面张力波。当压电基底211声波频率高于毛细波的频率时，液体的表面张力不足以维持其几何形状，发生雾化现象，所形成气溶胶液滴直径取决于毛细波波长，即气溶胶液滴直径取决于谐振频率。
雾化液液体在高频体声波即机械振动作用下雾化，完成了从大体积液体变成小液滴的物理变化过程，并且液体与金属电极层没有直接接触，解决了多孔陶瓷或者多孔棉条件下因必须采用高温方式雾化而导致的雾化液热裂解变质的弊端，更不会发生烧焦、积碳和重金属挥发等现象，本发明能够保持不同雾化液所特有的香精香料体系，最终使吸入者感受到与原始雾化液相对应的特有的口感，还原度更高。
本发明设计了以铌酸锂为压电基底的高频体声波芯片，该高频声波雾化芯片在1.8W的输入功率下就可以实现3mg/s的雾化量，解决了现有电热式雾化技术电能利用率低的问题，提高电能利用率，并且雾化的液滴直径可达到20μm，气溶胶粒径小且均匀。与现有声表面波雾化器相比，制造简单。
可以理解的，以上实施例仅表达了本发明的优选实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制；应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，可以对上述技术特点进行自由组合，还可以做出若干变形和改进，这些都属于本发明的保护范围；因此，凡跟本发明权利要求范围所做的等同变换与修饰，均应属于本发明权利要求的涵盖范围。
