Description

一种超声波电子烟雾化芯及其雾化器 技术领域
本发明涉及电子烟具，特别是一种超声波电子烟雾化芯及其雾化器。
背景技术
现有超声波电子烟雾化器中的超声波雾化片都是通过硅胶座来固定，也就是说硅胶座与超声波雾化片直接接触，由于硅胶座很软，因此硅胶座具有很强的吸收振幅和频率，即吸振的作用。超声波雾化片超声雾化烟油过程就是通过超声波雾化片振幅和频率产生高频振荡的过程，因此超声波雾化片所产生的振幅和频率有一部分会被硅胶座吸收，从而使振幅和频率变小，因此超声波雾化片产生高频振荡所需的能量没有完全被用于雾化烟油，从而使烟油雾化不够充分，能量损耗大，造成资源浪费。
另外，现有超声波电子烟雾化器中的超声波雾化片的上电极与电极组件之间都是通过焊接电子线方式导电，因此在超声波雾化片工作过程中或者安装的过程中容易出现焊点掉落或者导电不良的现象。
发明内容
本发明要解决的技术问题是克服现有技术的不足，提供一种能使超声波雾化片产生的高频振荡完全用于雾化烟油，超声振荡能量损耗小，烟油雾化充分的超声波电子烟雾化芯及其雾化器。
为解决上述技术问题，本发明提供了一种超声波电子烟雾化芯，其包括超声波雾化片和电极组件，所述电极组件包括一绝缘座，所述绝缘座的外周包覆外电极，所述外电极由硬质的导电薄片弯折形成，且所述外电极包覆在所述绝缘座上，并在所述绝缘座的上方弯折形成弹性的超声波雾化片安装区域，所述超声波雾化片安装区域包括由所述导电薄片一体弯折形成的弹性顶部和弹性底部，所述弹性顶部和弹性底部之间弹性夹持安装超声波雾化片。
本发明的外电极是硬质的导电薄片，超声波雾化片通过外电极弯折形成的弹性顶部和弹性底部的弹性夹持而固定，因此超声波雾化片与弹性顶部和弹性底部都是硬接触，弹性顶部和弹性底部不会吸收超声波雾化片高频振荡过程的振幅和频率，使超声波雾化片所产生高频振荡的振幅和频率全部用于雾化烟油，使烟油雾化效率更高，雾化更加充分。同时由于弹性顶部和弹性底部由外电极一体形成，并弹性夹持在超声波雾化片的边缘，使超声波雾化片的上、下表面边缘受到相同的弹性夹持力作用，实现受力平衡，因而不会影响超声波雾化片工作的振幅和频率，更不会因超声波雾化片的上、下表面边缘产生的应力不平衡而导致的超声波雾化片寿命变短。
优选地，所述超声波雾化片包括一压电陶瓷基体，所述压电陶瓷基体的上表面设置上电极，所述弹性顶部和弹性底部分别抵接在所述超声波雾化片的上、下表面，使所述超声波雾化片的上电极与所述外电极电连接，从而避免了通过焊接电子线实现外电极的电连接，使组装方便简单，并避免了超声波雾化片工作过程中因焊接电子线脱落导致的故障。
为了更好的实现超声波雾化片上电极与外电极的电连接，所述弹性顶部的底面上设置多个凸点，使所述弹性顶部与所述超声波雾化片的上电极通过所述凸点形成弹性抵接，使电性导通更好。
所述超声波雾化片安装区域上面的外电极向内弯折形成一体设置的超声波雾化片安装口，且该超声波雾化片安装口的上端口大于下端口。所述外电极在所述超声波雾化片安装口位置时先向内倾斜弯折再向外弯折，使所述超声波雾化片安装口内设置一变形斜部和一变形间隙。在组装时，超声波雾化片从上端口往下端口挤压，下端口在变形间隙内变形，然后才能将超声波雾化片挤压进超声波雾化片安装区域，从而使超声波雾化片被夹持在超声波雾化片安装区域内，使超声波雾化片的组装方便、可靠。因此，本发明不再需要硅胶座来固定超声波雾化片，从而减小了零部件，降低了使用成本，同时可以避免硅胶座在超声雾化过程中吸收超声波雾化片的雾化振幅和频率而使烟油出现雾化不充分的现象。
位于超声波雾化片安装区域下面的外电极内凹形成用于安装密封圈的凹槽，所述外电极的顶部覆盖所述储油体，且所述储油体的边缘往凹槽位置弯折并覆盖凹槽，所述密封圈套设在覆盖所述凹槽的储油体上，以固定储油体，防止储油体松动。
所述绝缘座上设有凸部，所述外电极上对应所述凸部设置凸骨，且所述凸骨正好包覆在所述绝缘座的凸部上。当雾化芯安装到雾化器内后，该凸骨可对烟油起到密封作用，从而防止烟油渗漏。
基于同一发明构思，本发明还提供了一种超声波电子烟雾化器，其包括内部设置油仓的油仓装置，所述油仓装置的底座内设置雾化芯安装空间，该雾化芯安装空间内安装上述超声波电子烟雾化芯。
所述雾化芯安装空间包括从上至下依次设置的第一、二、三空腔，第二、三空腔之间设置固定槽，所述外电极的凸骨卡设在所述固定槽内，且所述雾化芯的上段与第一空腔的侧壁之间设置与所述油仓的出油孔直接连通的储油间隙，所述储油体的侧部设置在所述储油间隙内，使储油体能将储油间隙的烟油运送到超声波雾化片上超声雾化。
所述超声波电子烟雾化器还包括吸嘴装置，所述油仓装置包括油仓上盖和油仓底座，油仓底座的上表面中部设置凸起的第一接合部，第一接合部内设置第二接合部，第一接合部上连接一外套管，该外套管与油仓上盖、吸嘴装置固定连接，使吸嘴装置、油仓上盖、油仓底 座连接成一体。
所述吸嘴装置内设置第一进气通道和第一出气通道，所述储油体与所述第二接合部底部之间设置用于将储油体的局部抵接在超声波雾化片上的压棉弹簧，使超声雾化片与第二接合部之间形成雾化腔，所述第一、二接合部之间设置与雾化腔连通的第一过气孔，所述第二接合部的中部设置与雾化腔连通的第二过气孔，第二过气孔内插设中空的内套管，所述外套管上设置与第一进气通道连通的进气孔，外套管的内壁与所述内套管的外壁之间形成第二进气通道，且所述第二过气孔经内套管的内腔与所述第一出气通道相连通，使第一进气通道、进气孔、第二进气通道、第一过气孔、雾化腔、第二过气孔、外套管内腔、第一出气通道相连通形成雾化器的气流通道。
与现有技术相比，本发明的优点在于：
1、本发明超声波雾化片通过外电极弯折形成的弹性顶部和弹性底部的弹性夹持而固定，使超声波雾化片上、下表面边缘受力平衡，使超声波雾化片在工作过程中能将全部的振荡能量用于雾化烟油，提高超声雾化的烟雾量和烟雾口感，以避免超声波雾化片上、下表面边缘受力不平衡影响超声波雾化片的振幅所导致的烟雾颗粒比较大，烟雾口感不细腻。
2、本发明超声波雾化片的上、下电极与外、内电极通过直接抵接而实现电连接，避免了通过焊接电子线实现电连接，进而避免了在超声波雾化片工作过程中焊接电子线脱落的现象。
3、本发明储油体直接覆盖在外电极顶端，再用密封圈固定其端部即可，因而组装方便，节省工时且不容易出现褶皱。

具体实施方式
以下结合具体优选的实施例对本发明作进一步描述，但并不因此而限制本发明的保护范围。
为了便于描述，各部件的相对位置关系(如：上、下、左、右等)的描述均是根据说明书附图的布图方向来进行描述的，并不对本专利的结构起限定作用。
实施例1：
如图1－图9所示，本发明超声波电子烟雾化芯3一实施例包括绝缘座35，该绝缘座35的中部设置内电极36，该绝缘座35的外周包覆外电极34。该外电极34由导电薄片，比如电镀铜片、电镀铁片等弯折而成，且该外电极34包覆绝缘座35，并在绝缘座35的上方向上延伸并弯折形成具有弹性的超声波雾化片安装区域341。该超声波雾化片安装区域341内安装超声波雾化片32，因此该超声波雾化片32在该超声波雾化片安装区域341内被弹性抵接或者弹性夹持。该超声波雾化片安装区域341的上边缘由导电薄片向超声波雾化片安装区域341内部倾斜弯折形成弹性顶部342，使得在安装超声波雾化片32后弹性顶部342向下抵压超声波雾化片32的上表面；下边缘由导电薄片向超声波雾化片安装区域341外部倾斜弯折形成弹性底部343，使得在安装超声波雾化片32后弹性底部343向上托住超声波雾化片32的下表面。
由于超声波雾化片安装区域341由外电极34一体弯折形成，因此超声波雾化片安装区域341通过其弹性顶部342和弹性底部343的张开弹力弹性夹持超声波雾化片32就可固定超声 波雾化片32，并使超声波雾化片上、下表面边缘受力平衡，以免超声波雾化片上、下表面受力不平衡导致的超声波雾化片32振幅变小，从而使烟油雾化不充分，烟雾颗粒较大，烟雾口感不细腻；以及避免超声波雾化片工作时负载加重，功耗高，使得超声波雾化片寿命减短的问题。
超声波雾化片32包括一压电陶瓷基体321，该压电陶瓷基体321的上表面全部丝印或烧结烘干设置有上电极322，也就是说上表面的边缘也设置有可以导电的上电极322，该压电陶瓷基体321的下表面设置下电极323，且下电极323位于该压电陶瓷基体321的下表面中部，也就是说下表面中部丝印或烧结烘干有下电极323。这样，通过弹性顶部342和弹性底部343分别抵接在超声波雾化片32的上、下表面边缘，由于弹性顶部342和弹性底部343共同围成超声波雾化片安装区域341，当超声波雾化片32安装在超声波雾化片安装区域341后，通过弹性顶部342和弹性底部343的自身弹力将超声波雾化片32夹紧，因此弹性顶部342与超声波雾化片32上表面的上电极322弹性接触，从而促使其电连接更加良好，也就是说超声波雾化片上电极322与外电极34的电连接更好。超声波雾化片32的下电极323与内电极36的弹簧直接抵接而实现电连接，即超声波雾化片32的上、下电极322、323的连接均不用焊接电子线实现连接导电，而是通过外电极34、内电极36同时与超声波雾化片32弹性抵接实现电连接，因此能够避免超声波雾化片32在组装过程或者工作过程中出现焊接电子线脱落的现象。
为了更好的实现超声波雾化片上电极322与外电极34的电连接，弹性顶部342的底面上可以设置一些凸点344，使弹性顶部342与超声波雾化片32之间形成局部的弹性抵接，使电性导通更好。
位于超声波雾化片安装区域341上面的外电极34向内弯折形成超声波雾化片安装口345，且该超声波雾化片安装口345的上端口3451大于下端口3452，即外电极34在超声波雾化片安装口位置向内倾斜再向外弯折(以超声波雾化片安装口为参照)，从而形成一变形斜部346和一变形间隙347。在组装时，超声波雾化片32从上端口3451往下端口3452挤压，下端口3452在变形间隙347内变形，然后才能将超声波雾化片32挤压进超声波雾化片安装区域341，从而使超声波雾化片32被夹持在超声波雾化片安装区域341内，使超声波雾化片32的组装方便、可靠。因此，本实施例中不再需要硅胶座来固定超声波雾化片，从而减小了零部件，降低了使用成本，同时可以避免硅胶座在超声雾化过程中吸收超声波雾化片的雾化振幅和频率，从而使雾化振幅和频率变小，进而使烟油出现雾化不充分的现象。
位于超声波雾化片安装区域341下面的外电极34内凹形成凹槽348，外电极34的顶部覆盖储油体31，且该储油体31的边沿往凹槽位置弯折并覆盖凹槽348，并在外电极34的凹槽348上套设密封圈33以固定储油体31的形状防止储油体31松动。组装储油体31时，先 将柔性的储油体31覆盖在外电极34的顶端，然后把储油体31的边沿往凹槽348位置弯折，当储油体31覆盖过凹槽348时，在凹槽348内套设密封圈33以固定储油体31，防止储油体31松动，这样使组装储油体31更加方便、轻松。本实施例中，储油体31优选采用棉质材质。
绝缘座35上设有用于与雾化器装设定位的凸部351，位于凹槽348下面的外电极34对应该凸部351外凸形成凸骨349，使外电极34的凸骨349正好包覆在绝缘座35的凸部351上。
相应地，如图10－图15所示，本发明超声波电子烟雾化器一实施例包括可相对旋转的吸嘴装置1和油仓装置2，吸嘴装置1包括固定在一起的吸嘴盖11和吸嘴底座14，油仓装置2包括固定在一起的油仓上盖21和油仓底座22。吸嘴装置1内设置第一进气通道13和第一出气通道12。油仓底座22的上表面中部外凸形成第一接合部227，该第一接合部227内设置第二接合部229，第一、二接合部227、229之间设置与雾化腔连通的第一过气孔228，第二接合部229的中部设置与雾化腔连通的第二过气孔230。第一接合部227上连接一外套管5，该外套管5同时与油仓上盖21、吸嘴装置1固定连接，从而通过外套管5将吸嘴装置1、油仓上盖21、油仓底座22连接成一体。第二接合部229的第二过气孔230内插设中空的内套管6，且该内套管6的内腔与第一出气通道12相连通；该外套管5上设置与第一进气通道13连通的进气孔51，外套管5的内壁与内套管6的外壁之间形成第二进气通道52，这样，使第一进气通道13、进气孔51、第二进气通道52、第一过气孔228、雾化腔、第二过气孔230、外套管内腔、第一出气通道12相连通形成雾化器的气流通道。
油仓上盖21和油仓底座22结合后形成油仓，油仓底座22的顶部设置与油仓直接连通的出油孔221，且油仓底座22内设置雾化芯安装空间，雾化芯3安装在该雾化芯安装空间内，且雾化芯3的储油体31与第二接合部229底部之间设置压棉弹簧4，不仅使超声雾化片32与第二接合部229之间形成雾化腔，而且使储油体31在压棉弹簧4的作用下，储油体31的局部抵接在超声波雾化片32上，从而避免超声波雾化片32被烟油浸泡，使其雾化速度更快(由于超声波雾化片32被储油体全面覆盖时，储油体存储的烟油会浸泡该超声波雾化片而使其雾化烟油的速度慢)。
该雾化芯安装空间包括从上至下依次设置的第一、二、三空腔222、223、224，第二、三空腔223、224之间形成用于卡设雾化芯绝缘座凸部的固定槽225。
雾化芯3组装时，将雾化芯3从油仓底座22的底部向上插入雾化芯安装空间，并使雾化芯上的凸骨349插设在固定槽225内，使得凸骨349可对烟油起到密封作用，进一步防止烟油渗漏。雾化芯3的上段与第一空腔222的侧壁围成储油间隙226，雾化芯3的顶端抵接在第一空腔222的顶部，该储油间隙226与出油孔221直接连通，故储油间隙226可以存储少 量的烟油，又因包覆在外电极34上的储油体31设置在储油间隙226内，所以储油体31能将储油间隙226的烟油运送到超声波雾化片32上用于超声雾化，即出油孔221、储油间隙226、储油体31形成雾化器的导油结构。
本发明雾化器使用时，当吸烟者吸烟时，空气从第一进气通道13进入，并经进气孔51、第二进气通道52、第一过气孔228到达雾化腔，同时，烟油从出油孔221、储油间隙226、储油体31流到超声波雾化片32上，经超声波雾化片32振荡，使其表面的烟油雾化，雾化的烟气混合外部空气经第二过气孔230、外套管内腔、第一出气通道12流出而同时被吸烟者吸食。
以上所述，仅是本申请的较佳实施例，并非对本申请做任何形式的限制，虽然本申请以较佳实施例揭示如上，然而并非用以限制本申请，任何熟悉本专业的技术人员，在不脱离本申请技术方案的范围内，利用上述揭示的技术内容做出些许的变动或修饰均等同于等效实施案例，均属于技术方案范围内。
