- electrostatic atomization technology refers to the process in which a liquid overcomes its own surface tension and breaks into droplets under the action of an electric field force.
- the process of implementing electrostatic spraying is relatively simple. Usually, it is only necessary to inject a liquid matrix with sufficient conductivity and moderate surface tension into a metal capillary; the capillary is connected to a DC voltage (about several thousand volts); and the ground electrode is several centimeters away from the capillary.

- the liquid absorption structure 40 is arranged on the auxiliary electrode 30, and is used to absorb the accumulated liquid on the auxiliary electrode 30, to prevent the accumulated liquid from discharging, and further to prevent the accumulated liquid from being connected to the nozzle assembly, causing a short circuit in the circuit or even burning out the related components, thereby greatly improving the stable operation time of the electrostatic atomization device.

- the second charge can be a negative charge
- the ion wind is a negative ion wind.
- the negative ion can be a negative oxygen ion, which can be formed by combining oxygen molecules in the air with free electrons.

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。
如图1所示，在本实施例中，该静电雾化装置1包括喷头组件10、除电结构20、辅助电极30、以及吸液结构40。该喷头组件10通过接入第一高压电，将液态基质形成带有第一电荷的第一气溶胶颗粒，并将其喷出。该除电结构20与喷头组件10同轴设置，用于产生带有第二电荷的离子风中和带有第一电荷的第一气溶胶颗粒，使其形成不带电荷的第二气溶胶颗粒被用户使用。在本实施例中，该第一电荷以及第二电荷为极性相反的电荷。该辅助电极30设置靠近所述喷头组件10的喷口设置，并与所述喷头组件10同轴设置，可接地设置，可与喷头组件10配合形成足够强的电场，从而使得喷头组件10顺利喷出带有第一电荷的第一气溶胶颗粒。另外辅助电极30的作用还可减小空间电荷的影响，确保每个喷头组件10能够稳定地喷出带有第一电荷的第一气溶胶颗粒。该吸液结构40设置于该辅助电极30上，用于吸附位于辅助电极30上的积液，防止存在积液放电现象，进而防止积液与喷头组件导通而导致电路出现短路甚至使得相关部件被烧坏，从而极大地提高静电雾化装置稳定运行时间。在本实施例中，该静电雾化装置还包括储液结构50，该储液结构50与喷头组件10连接，用于储存液态基质，并将所述液体基质输出至喷头组件10。
如图2至图3所示，在本实施例中，该喷头组件10包括喷头本体11、以及喷嘴12。喷头本体11可呈圆柱状，且为一端设置有开口111的中空结构，内侧形成有临时储液腔112。该开口111处设置端盖13盖合，并且可通过端盖13与储液结构50连接。该临时储液腔112与储液结构50连通，用于储存储液结构50输出的液体基质。在一些实施例中，该喷头本体11不限于呈圆柱状。该喷嘴12设置于该喷头组件10与开口111相被设置的端面上，并与临时储液腔112连通，并可通过接入第一高压电将液态基质形成带有第一电荷的第一气溶胶颗粒，并喷出带有第一电荷的第一气溶胶颗粒。
在本实施例中，该喷嘴12可以为多个，该多个喷嘴12设置于该喷头本体11远离储液结构50的端面上。在本实施例中，该多个喷嘴12可沿喷头本体11的周向间隔设置，在本实施例中，该多个喷嘴12可以围绕形成一圈，呈圆周排布，从而使得排布的数量最多又相互独立。当然，可以理解地，在其他一些实施例中，该多个喷嘴12可形成多圈排布。当然，可以理解地，在其他一些实施例中，该多个喷嘴12也可呈阵列式排布。每一喷嘴12可与临时储液腔112连通，用于雾化液态基质使其形成气溶胶颗粒。在本实施例中，该喷嘴12可以为毛细金属管，具体地，该喷嘴12可以为金属针管。每一喷嘴12远离该喷头本体11的一端形成有喷口121，该喷口121可以呈圆形。当然，可以理解地，在其他一些实施例中，该喷口121不限于呈圆形，可以呈方形、椭圆形或者其他形状。可以理解地，在其他一些实施例中，该喷嘴12不限于为多个，在其他一些实施例中，该喷嘴12可以为一个。
在本实施例中，该喷头组件10所接入的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12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4所示，在本实施例中，该除电结构20呈环状，可设置于喷头本体11远离该喷嘴12的一端，并与喷头本体11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12喷出的第一气溶胶颗粒在除电结构20上的吸附。该除电结构20与喷头本体11同轴设置，通过将除电结构20与喷头本体11同轴设置，可使得喷头组件10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12内侧壁上而无法喷出）。
除电结构20包括环状体21以及多个离子产生部22。该环状体21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21不限于为金属薄片卷绕形成。在本实施例中，该环状体21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21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22设置于该环状体21远离该基座30的一端，且可沿该环状体21的轴向间隔设置，且分别沿该环状体21的轴向向喷嘴12方向延伸。该多个离子产生部22的延伸方向与喷头组件10喷出方向相同，也即产生的离子风的流动方向与喷头组件10喷出第一气溶胶颗粒的流动方向一致。每一离子产生部22包括尖端221，该尖端221可朝喷头组件10的喷出方向延伸，该尖端221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22呈锯齿状，可通过激光切割金属薄片形成。需要说明的是，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，该除电结构20所接入的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20可采用负离子发生装置，该除电结构20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20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，该辅助电极30与喷头本体11同轴且间隔设置，该辅助电极30的横截面可大于或等于喷头本体11的横截面。在本实施例中，该辅助电极30包括第一侧30a以及第二侧30b。该第一侧30a，其中第一侧30a可与喷头本体11相对设置。该第二侧30b可与第一侧相背设置。
在本实施例中，该辅助电极30呈片状，包括片状本体31以及多个通孔32。该片状本体31大致呈圆形。该多个通孔32间隔设置于片状本体31上，且沿该片状本体31的周向间隔设置。该喷嘴12可与通孔32一一对应设置。该喷嘴12可设置于该通孔32的中轴线上。在本实施例中，该通孔32为圆孔，该喷嘴12可与该通孔32的圆心位于同一直线上，且部分穿设于通孔32的中心。该喷嘴12穿出通孔32部分的长度可以为1mm~5mm，进而可提高雾化效果，更好地形成泰勒锥，以及吸液结构40防止喷嘴12尖端积液，避免喷嘴12尖端与辅助电极30之间产生短路。在其他一些实施例中，喷嘴12的喷口121位于通孔32的中心，也即与通孔32的圆心重合设置。该通孔32的孔径大于喷嘴12的孔径（也即喷嘴12的孔径小于通孔32的孔径），该喷嘴12与该通孔32孔壁之间的间隙形成有强电场。在一些实施例中，该通孔32的孔径可以为3mm-20mm，进而可提高辅助电极通孔32与喷嘴12之间形成的电场强度，从而提高第一气溶胶颗粒受到的电场力，需要说明的是，在在匀强电场中根据E=U/d的计算公式可知，电压一定时，两极之间的距离越短，电场强度越大，在根据E=F/q的计算公式可知，也即该第一气溶胶颗粒受到的电场力越大。该通孔32的直径小于3 mm时，该通孔32容易积液放电，导致设备无法运行，若通孔32大于20mm，则需要的电压会过高，造成能源浪费。可以理解地，在一些实施例中，该通孔32不限于为多个，可以为一个。在一些实施例中，该通孔32不限于为圆孔，可以为方孔或者其他形状。
在本实施例中，辅助电极30还包括连接臂33，该连接臂33可以为两个，该两个连接臂33可沿该片状本体31的径向对称设置，用于辅助电极30的连接固定。当然，可以理解地，在其他一些实施例中，该连接臂33不限于为两个，可以为一个或者大于两个。在本实施例中，该连接臂33可与片状本体31一体成型。当然，可以理解地，在其他一些实施例中，该连接臂33也可以省去。该辅助电极30可采用其他结构固定。
在本实施例中，该辅助电极30的整体厚度可以为0.2mm，通过将该辅助电极30的厚度设置为0.2mm，进而可便于吸液结构40的安装固定，且可减小整体结构的尺寸。当然，可以理解地，在其他一些实施例中，该辅助电极30的厚度可以不限于0.2mm。
如图3至图6所示，在本实施例中，该吸液结构40设置于该辅助电极30的第二侧30b。该吸液结构40可通过设置连接结构连接固定于辅助电极30上。在本实施例中，该连接结构可以为粘贴结构，也即该辅助电极30与该吸液结构40可通过粘贴结构粘贴固定。当然，可以理解地，在其他一些实施例中，该连接结构不限于为粘贴结构，可以为卡扣结构或者其他。

在本实施例中，该吸液体41的材料可以为吸液棉，该吸液棉加工成本较低，且在雾化领域应用广泛，由于辅助电极20与喷头组件10形成电场可以达到更好的雾化效果，加上吸液棉可以有效地解决辅助电极20上的吸附积液问题，从而使静电雾化得以有效的实现。当然，可以理解地，在其他一些实施例中，该吸液结构40的材料不限于为吸液棉，可以为陶瓷、纤维素、有机高分子（比如PI）等绝缘吸液材料中的一种或多种。
在本实施例中，该吸液结构40的整体厚度可以为0.8mm~6mm，进而有利于吸附较多积液，当然，可以理解地，在其他一些实施例中，该吸液结构40的厚度不限于为0.8mm~6mm，该吸液结构40的厚度可根据实际情况增加或减小。
在本实施例中，该吸液体41可包括主体部411以及连接部412。该主体部411可呈圆形，其横截面形状以及尺寸可与片状本体31的横截面形状以及尺寸相当。该连接部412为两个，该两个连接部412沿该主体部411的径向设置，且设置于该主体部411的两相对侧，且与连接臂33一一对应设置，该连接部412可用于与外置结构连接固定。当然，可以理解地，在其他一些实施例中，该连接部412不限于为两个，可以为一个或者大于两个。在其他一些实施例中，该连接部412可以省去。
在本实施例中，该吸液结构40还包括过孔42，该过孔42可以为多个，该多个过孔42设置于该主体部411上，且沿该主体部411的周向间隔设置，并沿该主体部411的厚度方向贯穿设置。该多个过孔42可与该通孔32一一对应设置，也即与喷嘴12一一对应设置。在本实施例中，该过孔42可与通孔32同轴设置，其形状可与该通孔32的形状相同。在本实施例中，该过孔42可以为圆孔。当然，可以理解地，在其他一些实施例中，过孔42不限于为圆孔，可以为方孔或者其他形状。在本实施例中，该过孔42的尺寸可大于该通孔32的尺寸，具体地，该过孔42的径向尺寸可略大于通孔32的径向尺寸，可以选择地，该过孔42的孔径相比于辅助电极30的通孔32的孔径大0.4 mm -0.7mm，进而可避免辅助电极20与吸液结构40装配存在误差，且可避免主体部411遮挡住辅助电极30上的通孔32而造成短路风险。
经试验验证：未设置吸液结构40的静电雾化装置1在持续雾化0.1ml/min后，辅助电极30表面因吸附液态基质（吸附率40%）过多导致与喷嘴12发生短路；当贴附吸液结构40后，在同样的吸附率情况下1mm厚度的吸液棉，可以提升三倍工作时间；当吸液结构40体积增大（加大厚度或增加层数）储液量同时增加、雾化比提升、吸附率降低到常规水准＜10%时，可以满足正常电子雾化装置雾化需求。
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60，该动力机构60可与储液结构50连接，用于将储液结构50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60可以为增压泵，具体地，该动力机构60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60可向储液结构50中的液态基质增加压力，使得储液结构50中的液态基质沿下液通道12顺利下流至临时储液腔112。可以理解地，在其他一些实施例中，该动力机构60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70，该电压控制器70可与增压泵连接，用于对增压泵进行调控，进而控制该储液结构50中的压缩体积，从而控制储液结构50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70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80，该第一高压发生结构80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+3kV~+10kV。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+3kV~+10kV。该第一高压电可直接或间接作用于临时储液腔112中的液态基质或者作用于喷嘴12中的液态基质，使得喷嘴12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90，该第二高压发生结构90可与该除电结构20连接，可向除电结构20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20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7至图10示出了本发明静电雾化装置的第二实施例，其与第一实施例的区别在于，该喷头本体11、除电结构20、辅助电极30的片状本体31以及吸液结构40的主体部41的横截面呈矩形，该喷嘴12、通孔32以及过孔42呈阵列示排布。
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。
