为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
图1示出了本发明第一实施例中的静电雾化装置1。该静电雾化装置1可应用于医疗、美容、电子雾化等领域。该静电雾化装置1可在常温且高流量的情况下雾化粘度较大的液态基质，并且可以调控雾化形成的气溶胶颗粒的粒径，极大地减少有害物质的产生。具体地，该静电雾化装置1可通过调节控制参数（如流量，电压，极间距，喷头数目和孔径等），使得喷出气溶胶粒径可调范围为几微米到几十微米。与传统电子雾化技术（陶瓷和棉芯）相比，该静电雾化装置1所采用的静电雾化技术雾化相同质量的液态基质，所用的功率约为传统电子雾化技术的50%，大大降低了能耗。
需要说明的是，上述静电雾化技术是指液体在电场力的作用下克服自身表面张力破碎成液滴的过程。静电喷雾的实现过程比较简单，通常只需将具有足够电导率和适度表面张力的液态基质注入金属毛细管；毛细管接通直流电压（约数千伏）；距离毛细管若干厘米处是地极。其中，液态基质的电阻率一般选择为大于200ohm-m，更优选的是大于250ohm-m；液态基质的表面张力为15-20 dynes/cm，更优选的是20-35 dynes/cm；该液态基质的介电常数小于65，更优选的是小于45；粘度小于100cp，更优选的是小于50cp。在电场作用下，毛细管出口处的液体弯月面呈锥形，锥尖喷出极细的射流。这股射流在泰勒锥的锥尖下游分裂成为细小的带电液滴喷雾。鉴于液体弯月面的形态，这种模式称为锥尖射流（cone-jet）模式。锥尖射流模式的静电喷雾具有如下优点：气溶胶颗粒单分散性好、可获得气溶胶颗粒直径范围广、喷嘴不容易堵塞、理论雾耗比极低、沉积效率高。

该喷头组件40可通过接入第一高压电并在第一高压电的作用下形成带有第一电荷的第一气溶胶颗粒，且通过喷嘴42喷出。在本实施例中，该第一高压电可以为正高压电。该第一电荷可以为正电荷，也即该喷嘴42喷出的第一气溶胶颗粒带有正电荷。当然，可以理解地，在其他一些实施例中，该第一高压电也可以为负高压电，该第一电荷也可以为负电荷。
如图3至图6所示，在本实施例中，该除电结构50呈环状，一端可与基座30相接，且可位于该喷头本体41的外周，也即该除电结构50与喷头本体41的横截面可在同一平面上，也即在静电雾化装置的横截面上，二者可形成同心圆结构。当然，可以理解地，在其他一些实施例中，该除电结构50可设置于喷头本体41远离该喷嘴42的一端，并与喷头本体41在轴向上间隔设置，也即可在第一气溶胶颗粒流动方向的上游形成离子风，从而进一步减少喷嘴42喷出的第一气溶胶颗粒在除电结构50上的吸附。该除电结构50与喷头本体41同轴设置，通过将除电结构50与喷头本体41同轴设置，可使得喷头组件40喷出第一气溶胶颗粒的流动方向与离子风的流动方向一致，进而可以更好地中和喷出的第一气溶胶颗粒（使得该第一气溶胶颗粒在流出的过程中不会被吸附与喷嘴42内侧壁上而无法喷出）。
除电结构50包括环状体51以及多个离子产生部52。该环状体51可以为金属薄片卷绕形成。当然，可以理解地，在其他一些实施例中，该环状体51不限于为金属薄片卷绕形成。在本实施例中，该环状体51可以为圆环状。当然，可以理解地，在其他一些实施例中，该环状体51也可以为椭圆环状、矩形环状等。在本实施例中，该多个离子产生部52设置于该环状体51远离该基座30的一端，且可沿该环状体51的轴向间隔设置，且分别沿该环状体51的轴向向喷嘴42方向延伸。该多个离子产生部52的延伸方向与喷头组件40喷出方向相同，也即产生的离子风的流动方向与喷头组件40喷出第一气溶胶颗粒的流动方向一致。每一离子产生部52包括尖端521，该尖端521可朝喷头组件40的喷出方向延伸，该尖端521是用于产生带有第二电荷的离子，以中和带有第一电荷的第一气溶胶颗粒。在本实施例中，该离子产生部52呈锯齿状，可通过激光切割金属薄片形成。
在本实施例中，该除电结构50通过接入第二高压电并通过离子产生部52将入该腔体21中的空气电离形成带有第二电荷的离子风。所谓的离子风是指空间中流动的不是气体分子而是被电离形成带有设定电荷的离子。在本实施例中，该第二高压电为负高压电，该第二电荷可以为负电荷，也即该离子风为负离子风，具体地，该负离子可以为负氧离子，可以通过空气中的氧分子结合了自由电子形成，而之所以选择形成负氧离子，是因为负氧离子能有效加强气管粘膜上皮的纤毛运动，影响上皮绒毛内呼吸酶的活性，改善肺泡的分泌功能及肺的通气和换气功能，缓解支气管痉挛、增加肺活量、调整呼吸频率、镇咳等。负离子还能促进鼻粘膜上皮细胞的再生，恢复粘膜的分泌功能。哮喘、气管炎、儿童百日咳等疾病有良好效果此外，负离子还可以增强人体免疫力，提高人体自愈力，有效防治糖尿病，肿瘤等疾病，是人们日常养生保健的理想选择。也即喷雾的同时产生负离子，对用户而言产生的副作用相对较小，甚至没有，反而对用户身体是有益的。
在本实施例中，该除电结构50可采用负离子发生装置，该除电结构50不限于本发明的这种设计，其他能够产生负离子风的除电结构可以用于本发明中，比如碳刷。在其他一些实施例中，当该第一电荷为负电荷时，该除电结构50也可以为正离子发生装置，该第二电荷也可以为正电荷。
在本实施例中，该除电结构50与喷头组件40之间设置有隔离结构412。该隔离结构412套设于喷头本体41上。在本实施例中，可以为绝缘隔板，该绝缘隔板与该喷头本体41形成一体结构。通过设置该隔离结构412，可用于将除电结构50与喷头组件40绝缘设置，也即隔离正极和负极，避免正负极之间的空气被击穿从而连通正负极，产生安全隐患。当然，可以理解地，在一些实施例中，该隔离结构可以为该除电结构50与喷头组件40之间留设的间隔，或者涂覆于该喷头本体41外表面的绝缘层。当然，可以理解地，在其他一些实施例中，该隔离结构412可以省去。该喷头本体41可整体为绝缘材质制成。
如图7所示，在本实施例中，该静电雾化装置还包括辅助电极60。该辅助电极60位于该外壳20的内侧，且靠近外壳10远离该基座30的一端，并位于该喷头组件40喷出方向上。该辅助电极60可接地设置，可与喷头组件40配合形成足够强的电场，从而使得喷头组件40喷出的所述带有第一电荷的第一气溶胶颗粒。另外辅助电极60的作用还可减小空间电荷的影响，确保每个喷头组件40能够稳定地喷出带有第一电荷的第一气溶胶颗粒。在本实施例中，该第一气溶胶颗粒的粒径可以为1-5微米。该第一气溶胶颗粒带第一电荷，并被带第二电荷的离子风中和以及带出腔体21。
在本实施例中，该辅助电极60呈片状，包括片状本体61以及多个通孔62。该片状本体61大致呈圆形。该多个通孔62间隔设置于片状本体61上，且沿该片状本体61的周向间隔设置。该喷孔43可与通孔62一一对应设置。该喷孔43可设置于该通孔的中轴线上。在本实施例中，该通孔62为圆孔，该喷孔43可与该通孔62的圆心位于同一直线上或与通孔62的圆心重合设置。该通孔62的孔径大于喷孔43的孔径（也即喷孔43的孔径小于通孔62的孔径），该喷孔43与该通孔62孔壁之间的间隙形成有强电场。在本实施例中，该通孔62为3-20mm。该通孔62的直径小于3 mm时，该通孔62容易积液放电，导致设备无法运行，若通孔62大于20mm，则需要的电压会过高，造成能源浪费。在本实施例中，该通孔62的排布方式可与该喷孔43的排布方式相同。在其他一些实施例中，该通孔62不限于为多个，在其他一些实施例中，该通孔62也可以为一个。
在本实施例中，该辅助电极60还包括镂空结构63，该镂空结构63可设置于该辅助电极的中部。具体地，在本实施例中，该通孔62可沿该镂空结构63的周向间隔设置。该镂空结构63可以为圆孔，当然，可以理解地，在其他一些实施例中，该镂空结构63可不限于为圆孔，可以为方孔或者其他形状的孔。通过设置该镂空结构63可减少雾化后的气溶胶颗粒的吸附。当然，可以理解地，在其他一些实施例中，该镂空结构63可以省去。在本实施例中，该辅助电极60可通过设置连接结构64连接于外壳20的侧壁上，在一些实施例中，该连接结构64可一体成型于该片状本体61的侧壁，其可以为连接凸筋，一端可与外壳20卡接或者焊接固定。
再如图1所示，在本实施例中，该静电雾化装置还包括动力机构70，该动力机构70可与储液结构10连接，用于将储液结构10中的液态基质输出至喷头组件40。在本实施例中，该动力机构70可以为增压泵，具体地，该动力机构70可以为微型增压泵，进而有利于静电雾化装置结构小型化需求。该动力机构70可向储液腔11中的液态基质增加压力，使得储液腔11中的液态基质沿下液通道12顺利下流至临时储液腔411。可以理解地，在其他一些实施例中，该动力机构70不限于为增压泵。
在本实施例中，静电雾化装置还包括电压控制器80，该电压控制器80可与增压泵连接，用于对增压泵进行调控，进而控制该储液腔11中的压缩体积，从而控制储液腔11中液态基质被推出的质量，实现定量雾化，可以理解地，在其他一些实施例中，该电压控制器80可以省去。
在本实施例中，该静电雾化装置还包括第一高压发生结构90，该第一高压发生结构90可用于向喷头组件施加第一高压电。该第一高压电为正高压电。该第一高压电的电压可以为+3.5kv~ +5kv。可以理解地，其他一些实施例中，该第一高压电的电压不限于为+3.5kv~ +5kv。该第一高压电可直接或间接作用于临时储液腔411中的液态基质或者作用于喷嘴42中的液态基质，使得喷嘴42喷出的第一气溶胶颗粒带正电荷。当然，可以理解地，在其他一些实施例中，该第一高压电可以为负高压电。
在本实施例中，该静电雾化装置还包括第二高压发生结构100，该第二高压发生结构100可与该除电结构50连接，可向除电结构50施加第二高压电。在本实施例中，该第二高压电可以为负高压电，电压可以为-3KV~ -5KV。可以理解地，在其他一些实施例中，该第二高压电的电压不限于为-3KV~ -5KV。该第二高压电将经过该除电结构50的空气被电离形成带有第二电荷的离子风。在其他一些实施例中，该第二高压电不限于为负高压电，当该第一高压电为负高压电时，该第二高压电为正高压电。
图8示出了本发明静电雾化装置的第二实施例，其与该第一实施例的区别在于，该镂空结构63省去。
图9至图12示出了本发明静电雾化装置的第三实施例，其与该第二实施例的区别在于，该外壳20可以省去，该腔体21形成于该基座30中。该基座30的横截面可大致呈长方形。该喷头组件40、以及辅助电极60的片状本体61均长方形，该喷孔43以及该通孔62可呈矩阵排布。该除电结构50的环状体51可以为横截面呈长方形的环状。
图13示出了本发明静电雾化装置的第四实施例，其与该第三实施例的区别在于，该辅助电极60还包括镂空结构63，该镂空结构63设置于该片状本体61的中部，用于减少气溶胶颗粒吸附。
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。
