Description

一种超声波雾化片、雾化器及超声波电子烟 技术领域
本发明特别涉及一种超声波雾化片、雾化器及超声波电子烟。
背景技术
现有的超声波电子烟包括外壳，外壳内设有超声雾化片、导油机构和油仓，油仓通过导油机构与超声雾化片的雾化面相连通，油仓内的烟油或其它产烟物质通过导油机构导至超声雾化片雾化面，烟油或其它产烟物质在超声雾化片的高频雾化作用下产生烟雾，供用户吸食。
现有的超声波电子烟中，超声雾化片均为圆片状，其包括圆片状压电基体、固定设于压电基体一侧表面的表面电极、固定设于压电基体另一侧表面的驱动电极，工作时，将表面电极、驱动电极分别与电源两极相连，超声雾化片即可高频雾化工作。
由于圆片状超声雾化片需要利用圆柱状固定套固定，而固定套沿超声雾化片圆周边包围固定超声雾化片，因此超声雾化片的圆周边均被固定，因而限制了超声雾化片的高频工作振幅，影响雾化效果，烟雾量较小。同时，由于圆片状超声雾化片雾化效果相对较差，为提高雾化效果，超声雾化片的直径一般较大，导至超声波电子烟的尺寸较大。
发明内容
本发明的目的在于，针对上述现有技术的不足，提供一种超声波雾化片、雾化器及超声波电子烟，雾化效果好，烟雾量较大，尺寸较小。
为解决上述技术问题，本发明所采用的技术方案是：
一种超声波雾化片，包括片状压电基体、贴覆于压电基体一侧表面的表面电极、贴覆于压电基体另一侧表面的驱动电极，其结构特点是所述压电基体为长条形。
借由上述结构，由于压电基体为长条形，因而形成长条形超声波雾化片，该种超声波雾化片有两种组装方式。第一种，在组装时，用固定座夹紧固定超声波雾化片一段，超声波雾化片的另一段悬空。在振荡过程中，由于超声波雾化片一段被固定座夹紧固定，因而该段振幅比较弱。超声波雾化片另一段悬空、没有任何东西束缚，因而振幅比较大，雾化效果好，烟雾量大。第二种，用固定座夹紧固定超声波雾化片的中间区域，使得超声波雾化片的两端均处于游离状态。第二种方式下，超声波雾化片的两端均可以用于超声雾化发烟物质，并且两端的振幅最大，雾化效果，增大烟雾量；同时也可以将超声波雾化片的两端各雾化不同口味的发烟物质，最后两种不同口味的烟雾混合，满足用户对不同口味烟雾的追求，提高用户体验。
可见，由于本发明中超声波雾化片的雾化效果好，因而较小尺寸的超声波雾化片即能达到较大的烟雾量效果，超声波雾化片尺寸相对较小，有利于应用超声波雾化片的产品往小型化发展。
作为一种优选方式，所述压电基体由互连的振荡段及固定段组成，所述表面电极固定设于振荡段一侧表面，所述驱动电极固定设于振荡段另一侧表面。
借由上述结构，由于压电基体为长条形，因而形成长条形超声波雾化片。超声波雾化片由固定段和振荡段两段组成，使用超声波雾化片时，用固定座夹紧固定超声波雾化片的固定段，通过固定段支撑振荡段使超声波雾化片的振荡段悬空设置于雾化器内。在振荡过程中，由于固定段被固定座夹紧固定，因而固定段振幅比较弱。超声波雾化片的振荡段悬空，没有任何东西束缚，因而振幅比较大，雾化效果好，烟雾量大。由于本发明中超声波雾化片为长条形，所以在超声波雾化片与产烟物质接触面积一致也就是说雾化出烟雾量一致的情况下，使用该超声波雾化片的雾化器尺寸可以相对较小，有利于应用超声波雾化片的产品往小型化发展。
作为一种优选方式，所述表面电极与驱动电极均为矩形；或者，所述表面电极与驱动电极均为圆形。使得两电极通电后产生对应电位差的面积大，因此在条形超声波雾化片中可以提高振荡段的振荡面积及提升振荡强度，从而可以提升超声波雾化片的雾化效果。
作为一种优选方式，所述压电基体的一侧表面被表面电极全覆盖，所述压电基体的另一侧表面中心区域被驱动电极覆盖，表面电极面积与驱动电极面积之比为a：b，其中a大于b。
借由上述结构，雾化面积大，烟雾量大，雾化效果好。
作为一种优选方式，所述振荡段的一侧表面被表面电极全覆盖，所述振荡段的另一侧表面中心区域被驱动电极覆盖，表面电极面积与驱动电极面积之比为a：b，其中a大于b。
作为另一种优选方式，所述振荡段的一侧表面由固设有表面电极的贴覆区域及没有固设表面电极的裸露区域组成，贴覆区域和裸露区域沿振荡段长度方向设置，贴覆区域较裸露区域靠近固定段；表面电极面积与驱动电极面积之比为a：b，其中a大于b。
借由上述结构，表面电极与振荡段端部有距离，从而超声波雾化片在雾化过程中产生的热量可以向两端扩散，因此散热速度快，振荡效果更好，防止振荡段在工作过程中因高温而裂片，延长超声波雾化片的使用寿命。
作为一种优选方式，所述压电基体上还设有与表面电极相接的第一焊点、与驱动电极相接的第二焊点。
将电源的两极分别与第一焊点和第二焊点相连，即可实现电源两极与表面电极、驱动电极的电连接。
作为一种优选方式，所述第一焊点设于表面电极外边缘处，所述第二焊点设于驱动电极外边缘处。
借由上述结构，第一焊点直接设置在表面电极旁边，第二焊点直接设置在驱动电极旁边，避免使用导电引线连接焊点和电极，降低成本。
作为另一种优选方式，所述第一焊点和第二焊点均设于固定段外表面，所述压电基体上固定设有连接第一焊点与表面电极的第一导电引线，所述压电基体上固定设有连接第二焊点与驱动电极的第二导电引线。
借由上述结构，将第一焊点和第二焊点设于振幅较小的固定段，防止第一焊点和第二焊点在超声波雾化片振荡时被牵引脱落，保证导电可靠性及超声波雾化片工作可靠性。同时，第一焊点和第二焊点设于固定段，还可以避免在焊接过程中产生高温而影响振荡段的性能，延长超声波雾化片的使用寿命。
作为一种优选方式，所述第一导电引线形状为等腰梯形，第一导电引线的大端与表面电极平滑过渡相连，第一导电引线的小端与第一焊点平滑过渡相连；所述第二导电引线形状为等腰梯形，第二导电引线的大端与驱动电极平滑过渡相连，第二导电引线的小端与第二焊点平滑过渡相连。
借由上述结构，第一导电引线与表面电极过渡连接处、第二导电引线与驱动电极过渡连接处无大尖角，便于加工，粘设更稳固，且在超声波雾化片极化处理时减少应力集中，使用寿命长。
作为一种优选方式，所述表面电极与驱动电极均为圆形；所述振荡段和/或固定段的外端部为圆弧面。
借由上述结构，当外端部为圆弧面时，加工更方便。若振荡段和固定段外端部均为圆弧面，则在设覆电极加工时不用特意区分振荡段和固定段，节省制作时间和成本。
基于同一个发明构思，本发明还提供了一种超声波雾化器，包括外壳，外壳内设有固定座，其结构特点是外壳内还设有所述的超声波雾化片，所述固定座固设于超声波雾化片两侧壁的中间区域，使得所述超声波雾化片的两端均处于游离状态。
超声波雾化片的两端均处于游离状态，所以该超声波雾化片的两端均可以用于超声雾化发烟物质，并且两端的振幅最大，雾化效果，增大烟雾量；同时也可以将超声波雾化片的两端各雾化不同口味的发烟物质，最后两种不同口味的烟雾混合，满足用户对不同口味烟雾的追求，提高用户体验。
作为一种优选方式，所述压电基体的外边缘设有与表面电极相接的第一焊点，压电基体的外边缘设有与驱动电极相接的第二焊点；第一焊点和第二焊点均设于超声波雾化片的边缘 位置且在固定座固定超声波雾化片的固定区域内。
超声波雾化片的两端均处于游离状态，所以超声波雾化片两端的振幅最大，且固定座固定在超声波雾化片两边的中间区域，所以该中间区域的振幅较小，因此将第一焊点和第二焊点设于振幅较小的中间区域，防止第一焊点和第二焊点在超声波雾化片振荡时被牵引脱落，保证导电可靠性及超声波雾化片工作可靠性。
基于同一个发明构思，本发明还提供了一种超声波雾化器，包括外壳，外壳内设有固定座，其结构特点是外壳内还设有所述的超声波雾化片，所述压电基体由互连的振荡段及固定段组成，超声波雾化片的固定段通过固定座固定，超声波雾化片的振荡段悬空设置。
借由上述结构，使用时，用固定座夹紧固定超声雾化片的固定段，超声雾化片的振荡段悬空。在雾化过程中，由于固定段被固定座夹紧固定，因而固定段振幅比较弱。超声雾化片的振荡段悬空，没有任何东西束缚，因而振幅比较大，雾化效果好，烟雾量大。由于本发明中超声雾化片的雾化效果好，因而较小尺寸的超声雾化片即能达到较大的烟雾量效果，超声雾化片及超声波电子烟尺寸相对较小。

进一步地，外壳内设有限位板，限位板位于超声雾化片的一侧，导油机构位于超声雾化片的另一侧；限位板与超声雾化片的振荡段之间有间隙。
该间隙可以防止超声雾化片工作过程中阻碍振荡段的振幅变化，以及防止超声雾化片工作过程中产生的热量被限位板带走而影响烟雾温度的升高。
进一步地，所述外壳内设有雾化外套、雾化内套，导油机构为杯状，导油机构侧壁套设于雾化外套和雾化内套之间，导油机构外底面与超声雾化片雾化面相接触。
进一步地，所述雾化内套内设有隔板，隔板将雾化内套分隔成第一腔体和第二腔体，第一腔体与油仓相通，第二腔体与导油机构内底面相通；所述雾化内套与第一腔体相对应的侧壁上开设连通油仓与导油机构的过油槽。
进一步地，外壳顶部连有吸嘴，外壳内设有通气管，通气管的一端与进气孔相连通，通气管的另一端与第二腔体相连通，导油机构侧壁开设连通第二腔体与吸嘴的过气孔。

具体实施方式
如图1至图6所示，超声波电子烟包括外壳2，外壳2内设有固定座20、超声雾化片1、导油机构3和油仓4，超声雾化片1通过固定座20固定，油仓4通过导油机构3与超声雾化片1的雾化面相连通；所述超声雾化片1包括片状压电基体101、固定设于压电基体101一侧表面的表面电极102、固定设于压电基体101另一侧表面的驱动电极103，所述压电基体101为长条形；所述压电基体101由互连的振荡段106及固定段107组成，固定段107通过固定座20固定，振荡段106的表面与烟油接触，且通过高频振荡使烟油雾化生产烟雾，振荡段106悬空设置于超声波电子烟的雾化腔内。导油机构3将油仓4内的烟油传导到振荡段106进行雾化；所述导油机构3的材质为亲油性的导油棉，所述固定座20具有一定弹性的材质制作而成，比如硅胶等材质，所述压电基体101材质为压电陶瓷。
由于压电基体101为长条形，因而由长条形压电基体制作而成的超声雾化片1也为长条形，从而使得使用该超声雾化片1的超声波电子烟尺寸减小，方便用户携带。
在该实施案例中，该超声波电子烟的超声雾化片1通过固定座20夹设于该超声雾化片1的固定段107；超声雾化片1的振荡段106与导油棉接触；在雾化过程中，由于固定段107被固定座20夹紧固定，因而固定段107振幅比较弱，超声雾化片1的振荡段106悬空，没 有任何东西束缚，因而振幅比较大，雾化效果好，烟雾量大。
外壳2内设有限位板5，限位板5和油腔4之间形成雾化腔(未标注)；超声雾化片1的振荡段106插入雾化腔内，超声雾化片1的固定段107设置雾化腔外，且被固定座20夹紧固定；导油机构3的一端插入油腔4中，导油机构3的另一端延伸至雾化腔内并与超声雾化片1的振荡段106接触；在该实施案例中的导油机构3垂直于超声雾化片1的振荡段106，限位板5与超声雾化片1的振荡段106之间有间隙6，提高超声雾化片1在高频振荡过程中振荡段106振幅增大及提高雾化效果。
由于限位板5与超声雾化片1的振荡段106之间有间隙6，所以超声雾化片1工作过程中产生的热量散发到限位板5上慢，因此这些热量可以进一步的被烟雾吸收，提升烟雾口感，同时由于超声雾化片1为长条形，所以振荡段106在工作过程中产生的高温可以导至固定段107上，从而可以防止振荡段106在工作过程中因高温而裂片，延长超声雾化片1的使用寿命。
所述外壳2内设有雾化外套7、雾化内套8，导油机构3为长条形杯状结构，与超声雾化片1的形状一样，可以提高导油机构3与超声雾化片1的接触面积，导油机构3侧壁套设于雾化外套7和雾化内套8之间，导油机构3外底面与超声雾化片1雾化面相接触。
所述雾化内套8内设有隔板9，隔板9将雾化内套8分隔成第一腔体10和第二腔体11，第一腔体10与油仓4相通，第二腔体11与导油机构3内底面相通；所述雾化内套8与第一腔体10相对应的侧壁上开设连通油仓4与导油机构3的过油槽801，油仓4内的烟油通过过油槽801与导油机构3接触。
外壳2顶部连有吸嘴12，外壳2内设有通气管13，通气管13的一端与进气孔14相连通，通气管13的另一端穿过第一腔体10与第二腔体11相连通，导油机构3侧壁开设连通第二腔体11与吸嘴12的过气孔301。
第二腔体11为与超声雾化片1雾化面相通的空腔，超声雾化出来的烟雾存储在第二腔体11内，空气从进气孔14通过通气管进入第二腔体11，从过气孔301带走第二腔体11中的烟雾，通过吸嘴12进入用户口腔。
所述超声雾化片1的长度方向与电子烟的长度方向平行，利于超声波电子烟的小型化。
所述外壳2内设有弹簧15，弹簧15一端与雾化内套8外壁相抵接，弹簧15另一端与导油机构3内底面相抵接。弹簧15用于实现导油机构3与超声雾化片的可靠接触。
外壳2内还设有设有支架16、PCB板17和电池18，PCB板17、电池18、固定座20和雾化外套7均通过支架16固定。限位板5将固定座20固定在支架16上，从而固定超声雾化片1，防止超声雾化片1在工作过程中倾斜而影响雾化效果；油仓4开口处设有烟油盖21，打开烟油盖21，可往油仓4内注油。
外壳2侧壁设有用于控制超声波电子烟是否工作的按键19。
如图7至图10中示出超声雾化片实施例二的结构，实施例二中，超声雾化片1包括片状压电基体101、固定设于压电基体101一侧表面的表面电极102、固定设于压电基体101另一侧表面的驱动电极103，所述压电基体101为长条形。

所述压电基体101的外边缘设有与表面电极102相接的第一焊点104，压电基体101的外边缘设有与驱动电极103相接的第二焊点105。将电源的两极分别与第一焊点104和第二焊点105相连，即可实现电源两极与表面电极102、驱动电极103的电连接。
所述压电基体101材质为压电陶瓷。
第一焊点104和第二焊点105均设于超声雾化片1的固定段107。超声雾化片1由固定段107及振荡段106两段组成，因此在使用该超声雾化片1的超声波电子烟中，固定段107被固定座20固定，所以固定段107雾化振幅较小，将第一焊点104和第二焊点105设于振 幅较小的固定段107，防止第一焊点104和第二焊点105在超声雾化片1雾化时被牵引脱落，保证导电可靠性及超声雾化片1工作可靠性。同时，第一焊点104和第二焊点105设于固定段，还可以避免在焊接过程中产生高温而影响振荡段106的性能；超声雾化片1的振荡段106悬空设置，提高雾化量。
如图11至图14中示出超声雾化片实施例三的结构，实施例三中，超声雾化片1包括片状压电基体101、固定设于压电基体101一侧表面的表面电极102、固定设于压电基体101另一侧表面的驱动电极103，所述压电基体101为长条形，所述压电基体101由互连的振荡段106及固定段107组成，所述表面电极102固定设于振荡段106一侧表面，所述驱动电极103固定设于振荡段106另一侧表面。
所述压电基体101材质为压电陶瓷。
当表面电极102和驱动电极103通电后，振荡段106在电位变化的驱动下做高频雾化，振荡段106的雾化幅度最大，从而使接触在振荡段106表面上的烟油或其它产烟物质雾化产生烟雾。
所述表面电极102与驱动电极103均为矩形，可以提升超声雾化片的雾化效果。
所述振荡段106的一侧表面被表面电极102全覆盖，所述振荡段106的另一侧表面中心区域被驱动电极103覆盖，表面电极102面积与驱动电极103面积之比为3：2至4:1，本实施例的优选方案为2:1。

如图15至图16中示出超声雾化片实施例四的结构，实施例四重复实施例三，区别在于，实施例四中不包括第一导电引线108和第二导电引线109，所述第一焊点104设于表面电极102外边缘处，所述第二焊点105设于驱动电极103外边缘处。第一焊点104直接设置在表面电极102旁边，第二焊点105直接设置在驱动电极103旁边，避免使用导电引线连接焊点和电极，降低成本。

如图20至图22中示出超声雾化片实施例六的结构，实施例六重复实施例四，区别在于， 所述振荡段106的一侧表面由固设有表面电极102的设覆区域Ⅰ及没有固设表面电极102的裸露区域Ⅱ组成，设覆区域Ⅰ和裸露区域Ⅱ沿振荡段106长度方向设置，设覆区域Ⅰ较裸露区域Ⅱ靠近固定段107；表面电极102面积与驱动电极103面积之比为3：2至4:1，本实施例的优选方案为2:1。表面电极102与振荡段106端部有距离，从而超声雾化片1在雾化过程中产生的热量可以向两端扩散，因此散热速度快，雾化效果更好，防止振荡段106在工作过程中因高温而裂片，延长超声雾化片1的使用寿命。
如图23至图26中示出超声雾化片实施例七的结构，实施例七中，超声雾化片1包括片状压电基体101、固定设于压电基体101一侧表面的表面电极102、固定设于压电基体101另一侧表面的驱动电极103，其结构特点是所述压电基体101为长条形，所述压电基体101由互连的振荡段106及固定段107组成，所述表面电极102固定设于振荡段106一侧表面，所述驱动电极103固定设于振荡段106另一侧表面。所述表面电极102与驱动电极103均为圆形。

如图27至图28中示出超声雾化片实施例八的结构，实施例八重复实施例七，区别在于，实施例八中不包括第一导电引线108和第二导电引线109，所述第一焊点104设于表面电极102外边缘处，所述第二焊点105设于驱动电极103外边缘处。第一焊点104直接设置在表面电极102旁边，第二焊点105直接设置在驱动电极103旁边，避免使用导电引线连接焊点和电极，降低成本。

如图32至图34中示出超声雾化片实施例十的结构，实施例十重复实施例八，区别在于，所述振荡段106的一侧表面由固设有表面电极102的设覆区域Ⅰ及没有固设表面电极102的裸露区域Ⅱ组成，设覆区域Ⅰ和裸露区域Ⅱ沿振荡段106长度方向设置，设覆区域Ⅰ较裸露区域Ⅱ靠近固定段107；表面电极102面积与驱动电极103面积之比为2：1。表面电极102与振荡段106端部有距离，从而超声雾化片1在雾化过程中产生的热量可以向两端扩散，因此散热速度快，雾化效果更好，防止振荡段106在工作过程中因高温而裂片，延长超声雾化片1的使用寿命。
