Description

一种超声波雾化器 技术领域
本发明涉及电子烟具，具体涉及一种超声波雾化器。
背景技术
现有超声波电子烟雾化器均用导油棉与油仓直接连通实现导油，导油棉的材质一般采用芳纶、无纺布等。发明人发现，这种导油棉存在如下问题：
1、随着超声雾化的进行，油仓内烟油温度升高时，烟油粘度下降，使得烟油在导油棉上的流动速率迅速加快，导油棉的导油量增多，使超声波雾化片上的供油过多，容易造成超声波雾化片被烟油浸泡等问题；
2、在烟油的温度随着超声雾化的进行而温度升高，粘度变小的同时，导油棉在吸收烟油后，导油棉的孔间隙增大也使得烟油在导油棉上的导油速率加快，容易进一步造成超声波雾化片被烟油浸泡的现象。
发明内容
本发明所要解决的技术问题是，克服现有电子烟雾化器易受温度影响导致烟油在导油体上导油速度加快的不足，提供一种导油速率不受烟油温度升高影响的超声波雾化器。
为解决上述技术问题，本发明提供了一种超声波雾化器，其包括导油组件，所述导油组件包括与烟油直接接触的导油陶瓷、位于所述导油陶瓷下面并与所述导油陶瓷直接接触的导油棉、位于所述导油陶瓷与所述导油棉之间并将所述导油棉抵持在雾化片上的弹簧，且所述导油陶瓷为实心陶瓷体，所述导油陶瓷上一体成型用于传导烟油的微孔。
本发明导油组件采用两种不同导油材质(导油陶瓷和导油棉)组合而成，且导油组件上段为孔隙度不变(导油陶瓷的孔隙度在其成型后已经确定)的导油陶瓷，使得由导油陶瓷的微孔构成的烟油通道的口径不会因浸泡烟油而发生膨胀或收缩，即导油陶瓷利用其材质特性保证了其导油通道的口径一定，进而保证了单位时间内经导油陶瓷传导的烟油量一定，不会出现因烟油粘度降低而导油速率不稳定的状况；导油组件下段为导油棉，由于导油棉在烟油量多时会膨胀，烟油量少时会相应地收缩，这种特性使得导油棉的导油量不稳定，因此在本发明中设计为导油棉不与油仓直接连接，而是通过导油陶瓷与油仓连接，以通过导油量稳定的导油陶瓷将定量烟油传导至导油棉内，再通过导油棉将烟油输送至雾化片的雾化表面进行超声雾化，使传导到雾化片雾化表面的烟油量也是定量，从而使雾化片上烟油的雾化效率更高，烟雾量更为稳定，并能减少或避免雾化片被烟油浸泡而吸食到烟油的现象。
另外，导油棉相对柔软，在组装时与雾化片抵持接触性更好，能使烟油渗透到雾化片表面更及时，超声波雾化器的雾化效果更好。同时，导油棉很薄，由于超声雾化过程中产生的 烟雾有一定动力，当烟雾穿过导油棉喷向上面的导油陶瓷时，导油陶瓷能吸收烟雾中的大颗粒烟油滴，因此本发明可以减少用户吸食到烟油滴的概率，提升用户体验。
进一步地，导油陶瓷与导油棉可以通过高温胶粘连在一起，或者通过夹持的方式将导油棉与陶瓷稳定连接在一起，以提高生产可靠性，并方便组装。
具体的，所述导油组件安装在储油组件的下部，所述储油组件上设有连通油仓与雾化腔的安装槽，且所述导油组件经所述安装槽安装在所述储油组件内。
进一步地，所述安装槽的顶部设置朝所述安装槽凸出的卡扣部，所述安装槽内设置安装台阶，所述导油陶瓷的下表面置于所述安装台阶上，所述导油陶瓷的上表面被所述卡扣部卡扣固定，从而可防止组装后的导油陶瓷从安装槽内脱落掉出。
为使导油陶瓷安装稳定，所述导油陶瓷包括与油仓内烟油直接接触的瓷体、设置于瓷体底部的至少两个引油脚；所述安装台阶为两级台阶，所述瓷体的两端置于第一级安装台阶上，所述引油脚置于第二级安装台阶上。
为更好地固定导油棉和传导烟油，所述导油棉的两端包覆在所述导油陶瓷的底部，并被所述导油陶瓷抵压安装在所述安装槽内。
具体的，所述超声波雾化器还包括相互连接的储油组件和雾化组件，所述雾化组件包括雾化头，所述雾化头包括具有导电性的中空雾化套，雾化套的内腔内从上至下依次设置用于超声雾化的雾化片、用于支撑雾化片的绝缘座、用于将雾化片与外部电源电连接的电极组件。
具体的，所述导油陶瓷与所述雾化片之间设置雾化腔，所述储油组件内设置连接雾化腔与外部大气的出气通道，所述雾化组件及所述储油组件内设置连接外部大气与雾化腔的进气通道。
为简化雾化片的电连接方式，所述雾化套的上端与所述雾化片的上表面电极抵触连接，所述雾化套的下端与所述电极组件的负极连接端电连接，所述雾化片的下表面电极与所述电极组件的正极连接端电连接。
与现有技术相比，本发明的有益效果为：
本发明采用导油陶瓷与导油棉组合导油，并且导油陶瓷与油仓内烟油直接连接，然后再通过导油棉将烟油传导至超声波雾化片上，由于导油陶瓷的导油速率不受烟油温度影响，所以在超声雾化过程中导油组件的导油量一定，使得烟油超声雾化的雾化效率高，烟雾量稳定，避免了超声波雾化片被烟油浸泡而雾化不充分导致用户吸到烟油滴的现象，以及因烟油量小而使超声波雾化片干烧的现象。

具体实施方式

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6所示，本实施例的雾化器包括储油组件1、设置在储油组件1底部的导油组件2和与储油组件1卡设结合的雾化组件3。

导油棉22的两端被导油陶瓷21的两个引油脚212抵持在安装槽121的第二级安装台阶124 上，并且导油棉22的两端包覆在引油脚212上。
导油陶瓷21的瓷体211和引油脚212采用相同材料一体烧结成型，瓷体211与油仓13内烟油直接接触，并吸收和传导烟油至引油脚212、导油棉22，由于烧结成型后的导油陶瓷21的孔隙度稳定(孔隙度在导油陶瓷21烧结生产后就已确定)，故不管烟油温度是常温还是高温(未雾化的温度),烟油的粘度是否降低，单位时间内通过导油陶瓷21的烟油量一定，导油陶瓷21的导油速率稳定，因此导油棉22上吸收和传导的烟油量稳定，从而可避免与导油棉22接触的雾化片322因烟油量少而干烧或因烟油量多而被烟油浸泡的现象。
为防止组装后导油陶瓷21脱落掉出，所述塞体12上的卡扣部122扣住导油陶瓷21。

雾化套321的上端与雾化片322的上表面电极抵触连接，雾化套321的下端与电极组件324的负极连接端3242电连接，雾化片322的下表面电极与电极组件324的正极连接端3241电连接。
雾化片322与导油棉22的底部接触，雾化片322与导油陶瓷21之间形成雾化腔4，储油组件1内设置连接雾化腔4与外部大气的出气通道14，雾化组件3内及储油组件1的下部设置连接外部大气与雾化腔4的进气通道33。
本实施例使用时，用户从储油组件1的出气通道14的外端吸食，外部空气从进气通道33进入到雾化腔4，烟油从油仓13经导油组件2传导到雾化片322上，雾化片322经雾化套321、电极组件324与外部电源电连接实现超声雾化，超声雾化后的烟雾经出气通道14流出至用户口腔而被吸食。
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。
