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。
如图1－图15所示，本发明超声波雾化器一实施例包括外壳1和雾化芯2。外壳1用于使用时手持，且外壳1上设置便于用户抽吸的吸嘴11。雾化芯2的两端都设置有密封环21，外壳1套在雾化芯2的外面并且与雾化芯2两端的密封环21抵接，使外壳1的内壁与雾化芯2之间形成环绕雾化芯2的油仓3。雾化芯2内部的超声波雾化片22设置在油仓3的中部，因此当超声波雾化片22工作时，超声波雾化片22所释放的热量被环绕超声波雾化片22的烟油吸收，从而避免了这些热量被外壳1吸收而使外壳1发烫(外壳吸收热量后发烫，有烫伤用户的风险)，同时提高了超声波雾化片22的使用寿命。
本实施例中超声波雾化片22沿超声波雾化器的纵向延伸设置，以使在竖直放置该超声波雾化器时，超声波雾化片22呈竖直状态，(即超声波雾化片22竖直设置在雾化芯2内)。
本实施例中超声波雾化片22包括压电陶瓷基体，且该压电陶瓷基体为实心陶瓷制成，即压电陶瓷基体表面没有任何小孔，烟油无法穿过该压电陶瓷基体。所述压电陶瓷基体包括相对设置的第一表面221和第二表面222，第一表面221上覆盖设置第一电极2211，第一电极2211具有延伸到第一表面221底边的第一导电触点22111，第二表面222上覆盖设置第二电极2221，第二电极2221具有延伸到第二表面222底边的第二导电触点22211。第一、二电极2211、2221对称设置在压电陶瓷基体的第一表面221和第二表面222上，且第一、二电极2211、2221在第一、二表面221、222上的覆盖区面积相等，使超声波雾化片22的第一、二表面电 荷数的绝对值相等，避免了因电荷数的绝对值不相等而产生热量的现象。
本实施例中，第一表面221和第二表面222上的电极覆盖区面积是非电极覆盖区面积的1/4－2/3。
为使超声雾化片22的组装更为顺滑，压电陶瓷基体的顶部设置为圆弧面223，压电陶瓷基体的底部设置为方形限位面224。很明显，压电陶瓷基体的形成不局限于图7、8所示形状，比如，也可如图9所示，将压电陶瓷基体整体设置为圆形。
超声波雾化片22的第一、二导电触点22111、22211分别经电极片27电连接外部供电电源，供电电源产生高频电压或高频电流施加在第一、二导电触点22111、22211上，压电陶瓷基体产生压电效应，即产生高频振荡，从而使得第一、二表面221、222上的电极覆盖区集聚大量电荷，并产生电位，使落到第一、二表面221、222的电极覆盖区的烟油同时在压电陶瓷基体的高频振荡下雾化成气体。在此过程中，由于第一、二电极2211、2221对称设置在压电陶瓷基体的第一表面221和第二表面222上，且第一、二电极2211、2221在第一、二表面221、222上的覆盖区面积相等，使超声波雾化片22的第一、二表面具有电荷数的绝对值相等，从而避免了因电荷数的绝对值不相等而产生热量的现象，且超声波雾化片22的第一、二表面能利用同一供电电源同时进行超声雾化，提高了能源利用率及烟油的雾化效率。
本实施例中超声波雾化片22的第一、二表面上的第一、二电极都与导油体23(导油棉)的中部接触，且导油体23的两端伸入油仓3，使油仓3内的烟油能经导油体23传导至超声波雾化片22的第一、二电极上进行超声雾化，以充分使用驱动超声波雾化片工作的电量。
导油体23由软性导油材质制成，比如棉。
本实施例中雾化芯2还包括基座24、固定座25和抵压件26。
基座24的内腔从上至下依次设置为第一腔体241、出气道242、插入槽243。第一腔体241靠近外壳1的吸嘴11设置，且第一腔体241的横截面积大于出气道242的横截面积，所以在吸烟时，大颗粒烟油滴会凝结在第一腔体241内，以避免用户吸食到烟油。插入槽243的底部设置插入口2431，用于将固定座25插入插入槽243内，且基座24上设置用于安装抵压件26和导油体23的安装槽244。基座24上还设置用于连通油仓3和安装槽244的进油槽245。
固定座25的上部设置有用于置入超声波雾化片22的穿孔251，穿孔251内设置用于固定超声波雾化片22的固定槽252。为使超声波雾化片22稳定置于穿孔251的固定槽252内，穿孔251的形状与超声波雾化片22的外形一致。固定座25下部的两表面上竖直设置连通雾化腔28的电极槽253和气槽254，以使外部空气可通过气槽254流经超声波雾化片22的第一、二表面221、222，且电极槽253内安装所述电极片27，超声波雾化片22的第一、二导 电触点22111、22211分别与一电极片27连接。
抵压件26的两侧设置抵压端262，抵压端262的外侧设置为抵压面261，其中抵压面261用于将导油体23抵压在安装槽244内，抵压端262用于将导油体23抵持在超声波雾化片22上使导油体23的中部与超声波雾化片22的第一、二电极接触。抵压件26的中部与超声波雾化片22之间设置雾化腔28，两个所述抵压件的抵压端262上分别设置连通雾化腔28和油仓3的透气槽2621，使进入雾化腔28的部分气体可通过透气槽2621进入油仓3中，使油仓3内烟油流出更为顺畅。
雾化芯2装配时，先将超声波雾化片22竖直放置在固定座25的固定槽252内，并在固定座25两侧的电极槽253内放置电极片27，使超声波雾化片22的第一、二导电触点22111、22211与电极片27实现电连接，同时固定座25两侧的气槽254分别对正超声波雾化片22的第一、二表面221、222；然后再将固定座25从基座24的插入槽243插入到基座24的下端，此时超声波雾化片22的第一、二电极均与基座24两面的安装槽244对齐；最后在安装槽244内放入导油体23，并使基座24上的进油槽245连通导油体23的端部，并用抵压件26的抵压面261将导油体23抵压在安装槽244的侧壁，同时用抵压件的抵压端262使导油体23的中部与超声波雾化片22的第一、二电极2211、2221接触。
超声波雾化器使用时，油仓3内的烟油通过基座24上的进油槽245进入到导油体23内，再被导油体23传导至超声波雾化片22上，并在超声波雾化片22产生的高频振荡下超声雾化成烟雾。
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。
