Description

一种超声波雾化器及电子烟 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及电子烟。
背景技术
现有超声波电子烟雾化器的雾化腔顶面和底面几乎平行，且进气入口和烟雾出口相隔较近，使得进气气流在雾化腔内与超声波雾化片的雾化表面不能形成一个角度，使雾化过程中飞溅的烟油滴容易随气流从烟雾出口流出，致使用户总是吸食到烟油滴，影响吸烟体验感。
另外，现有超声波电子烟雾化器中导油陶瓷与超声波雾化片的雾化区域间接接触，也就是通过导油陶瓷将雾化棉抵压在超声波雾化片的雾化区域上，因此导油陶瓷会阻碍或占用超声波雾化片的雾化区域部分面积，使得超声波雾化片对烟油的雾化量变小，因此烟雾量变小；同时导油陶瓷快速吸收超声波雾化片在雾化烟油的过程中释放的能量，使油仓内的烟油温度升高，从而影响烟油内部其他混合物分解或者不稳定，使烟油的保质期缩短，导致烟油被雾化后的烟雾口感变差。
发明内容
为了克服现有技术中用户易吸食到烟油的技术问题，本发明提供一种能避免用户吸食到烟油滴的超声波雾化器及电子烟。
为解决上述技术问题，本发明提供了一种超声波雾化器，其包括带有进气口和烟雾出口的雾化腔，所述雾化腔的底部安装超声波雾化片，所述雾化腔的顶面设置为第一斜面，所述第一斜面与所述超声波雾化片之间设置20°-75°夹角，所述进气口设置在第一斜面的底端，所述烟雾出口设置在所述第一斜面的顶端，且所述进气口和所述烟雾出口分别设置于所述雾化腔的相对两侧，所述烟雾出口的底面高于所述进气口的顶面，使所述超声波雾化片上面形成从所述进气口到所述烟雾出口的倾斜向上的气流通道。
发明人发现：超声波雾化器使用时，靠近超声波雾化片雾化区域的烟雾混合有很多飞溅烟油滴，如果大气流经过雾化区域附近时，容易将这些烟油滴带进用户口腔中，使用户吸食到烟油，从而影响烟雾口感；离雾化区域比较远的烟雾与空气混合及扩散形成比较稀薄的烟雾，比较容易被气流带走。因此，本发明巧妙地将雾化腔的顶面设置为与超声波雾化片的雾化区域呈20°-75°夹角的第一斜面，并将雾化腔的进气口设置在第一斜面的底端，且进气口呈渐开状，烟雾出口设置在第一斜面的顶端，且进气口和烟雾出口分别设置于雾化腔的相对两侧，烟雾出口的底面高于所述进气口的顶面，使所述超声波雾化片上方形成从所述 进气口到所述烟雾出口的倾斜向上的气流通道。当进气气流从雾化腔的进气口进入雾化腔后，大部分被雾化腔的顶面引导倾斜向上流动到达烟雾出口，此过程中，由于进气口呈渐开状，因而雾化腔内的气流流速小于进气口的气流流速，且靠近第一斜面的气流流速大于靠近超声波雾化片表面的气流流速，因而靠近超声波雾化片表面的烟雾中的烟油滴能在自身重力作用下直接掉落在超声波雾化片上重新参与超声雾化，使流动到烟雾出口的烟雾中烟油滴减少，避免烟油滴进入用户口腔。另外，由于靠近第一斜面的气流流道最短，大部分进气气流(流速比较快的气流)将沿着第一斜面流动至烟雾出口，即大部分进气气流经过烟雾的末端，将离超声波雾化片雾化区域表面比较远的烟雾带至烟雾出口，被用户吸食，提升烟雾口感，小部分进气气流(流速比较慢的气流)经过烟雾的始端也就是雾化区域表面，靠近雾化区域表面的含有大颗粒烟油滴的烟雾在靠近烟雾出口处撞击在雾化腔内壁上并凝结，在撞击的同时，少部分气流在自身重力作用下沿雾化腔内壁返回到超声波雾化片上再次进行雾化,既可以充分利用烟油，又可以防止用户吸食到烟油滴。
优选地，所述超声波雾化片的雾化区域上方放置导油陶瓷，所述导油陶瓷的中部设有过气通道，且所述过气通道对应所述超声波雾化片的雾化区域中心设置，即使过气通道对应设置在超声波雾化片振荡最为激烈的位置，既可以使超声波雾化片超声振荡最强的雾化区域表面不被导油陶瓷覆盖，也不会阻碍超声波雾化片中心高频振荡雾化出来的烟雾及时排出，同时还可以吸收高频振荡过程中飞溅的烟油滴。
为避免导油陶瓷的过气通道顶面影响气流倾斜向上流动的趋势，所述过气通道的顶面设置为第二斜面，且所述第一斜面与所述第二斜面位于同一斜面上。
优选地，所述导油陶瓷整体呈n型，使导油陶瓷既可以将烟油传导至超声波雾化片的雾化区域，又不至于因导油陶瓷将超声波雾化片的雾化区域基本覆盖而影响超声雾化效率，同时，超声波雾化片雾化区域表面只有一层薄薄的储油体存储较少烟油量(烟油量＜0.15mg)，从而使得超声波雾化片启动快，出烟快，烟油雾化充分，产生的烟雾能达到最大化，满足用户对烟雾的需求。另外，所述导油陶瓷的内部设置n型导油槽，导油槽的顶端与油仓连通，不仅使导油陶瓷两侧导油均匀，而且导油槽的底部尽可能接近导油陶瓷的两侧底部，使烟油通过导油陶瓷渗透到超声波雾化片的距离缩短，进而使供油速度加快，避免超声波雾化片工作时烟油供应速度慢而引起干烧的现象。
优选地，所述过气通道的顶面设置回收槽，当超声波雾化片高频振荡雾化烟油时烟雾喷向回收槽内部，烟雾中的大颗粒烟油滴被回收槽吸收之后，烟雾再经烟雾出口排出，从而避免用户吸食到烟油滴，提升用户体验。
优选地，所述导油陶瓷的底面将储油体抵持在所述超声波雾化片的雾化区域上， 使导油陶瓷传导到超声波雾化片上的烟油能暂存在储油体上，不至因导油陶瓷供油不足而导致的干烧现象。
优选地，所述导油陶瓷与所述超声波雾化片相隔一距离安装，所述导油陶瓷的内部设置n型导油槽，所述导油槽的顶端与油仓连通；所述导油槽的底部贯穿所述导油陶瓷的底部，使所述导油槽的下段同时作为储油体固定槽，储油体的两端插设固定在所述储油体固定槽内，所述储油体的中部被弹簧抵持在所述超声波雾化片的雾化区域。
将导油陶瓷相隔超声波雾化片一距离安装，使导油陶瓷不会覆盖超声波雾化片的雾化区域，因而不会影响超声波雾化片雾化区域的雾化量，导油陶瓷吸收的超声雾化热量也相应减少，因而通过导油陶瓷传递给油仓内烟油的热量更小，对油仓内烟油的物化性质影响较小，不会改变烟油的保质期，也不会导致因烟油变质而出现的烟雾异味。
优选地，所述储油体从两端往中间分别设置固定段、过渡段和接触段，所述固定段插设固定在所述储油体固定槽内，所述接触段被弹簧抵持在所述超声波雾化片的雾化区域并正对所述导油陶瓷的下方设置。
如此，使烟油可以经过储油体的固定段传导至接触段并最终到达超声波雾化片的雾化区域，也可以经过导油陶瓷直接渗透到储油体的接触段并最终到达超声波雾化片的雾化区域，而且，当储油体固定段与储油体固定槽配合过紧，不利于烟油和气体通过固定段时，烟油和气体可以通过导油陶瓷相互渗透，实现油仓内烟油和气体置换，从而使烟油沿着储油体和导油陶瓷之间的空间顺利传导至超声波雾化片上供给超声雾化形成烟雾，避免烟油量供给不足而产生干烧的现象，另外，由于导油陶瓷的孔隙度是一定的，所以其渗透烟油和气体更加均匀，可以防止超声波雾化片的雾化区域表面烟油过多而雾化不充分以及吸食到烟油滴的现象。
具体地，所述超声波雾化器还包括相互卡设结合的外壳和塞体，所述外壳与所述塞体之间设置油仓，所述塞体的中部从上至下依次设置通油槽、导油陶瓷固定槽、所述雾化腔、雾化芯安装槽，所述雾化芯安装槽的一侧设置连通所述进气口的进气槽，所述雾化芯安装槽内安装雾化芯。雾化芯(3)包括具有导电性的中空雾化套(31)，所述雾化套(31)的内腔从上至下依次设置所述超声波雾化片(32)、绝缘座(33)和PCB板(34)。
为解决上述技术问题，本发明还提供了一种电子烟，其包括上述超声波雾化器。
与现有技术相比，本发明的有益效果为：
1、雾化腔的顶面与超声波雾化片的雾化区域表面形成夹角，使得经过雾化腔的主气流与超声波雾化片也成夹角，从而让气流带走的飞溅烟油滴减少，避免了用户吸食烟油滴，提升用户体验感。
2、导油陶瓷与超声波雾化片不接触，既不影响超声波雾化片雾化烟油的面积，也不影响烟油传导的速度，提升了烟油的雾化量，使烟雾口感更为醇厚；
3、导油陶瓷与超声波雾化片不接触，可以避免超声波雾化片雾化烟油时释放的能量被导油陶瓷吸收而传导至烟油中影响烟油的保质期，进而使烟雾异味；
4、雾化腔的顶面与底面形成夹角，使得经过雾化腔的气流与超声波雾化片也成夹角，从而气流带走的飞溅烟油滴减少，避免了用户吸食烟油滴，提升用户体验感。

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，本实施例的超声波雾化器包括本体1、导油组件2和雾化芯3。
本体1包括外壳11和塞体12，外壳11和塞体12相互接合后在其内部形成油仓13。外壳11上设置吸嘴111和出气管112。塞体12优选为具有弹性的硅胶塞。塞体12的中部从上至下依次设置通油槽121、导油陶瓷固定槽122、雾化腔123、雾化芯安装槽124，雾化芯安装槽124的一侧设置进气槽125，且塞体12的顶部设置气管插孔126，气管插孔126与外壳11上的出气管112的底端相连接形成出气通道。
导油组件2包括安装在导油陶瓷固定槽122内的导油陶瓷21和位于导油陶瓷21底面的储油体22。
雾化芯3包括具有导电性的中空雾化套31，雾化套31的内腔从上至下依次设置超声波雾化片32、绝缘座33、PCB板34。绝缘座33和PCB板34的中部设置电极组件35。超声波雾化片32的上表面设置上表面电极和雾化区域，下表面设置下表面电极。雾化套31的上端与超声波雾化片32的上表面电极抵触连接，雾化套31的下端包覆在PCB板34的底面作为第一电极连接端，超声波雾化片32的下表面电极与电极组件35电连接，电极组件35作为第二电极端。
雾化芯3安装在雾化芯安装槽124内，雾化腔123设置在雾化芯3的上方，且超声波雾化片32作为雾化腔123的底面(雾化套31顶端具有用于曝露雾化片32的雾化区域的开口)，塞体12内设置有雾化腔123。
雾化腔123的顶面设置为第一斜面1231，第一斜面1231与超声波雾化片32的上表面之间具有20°-75°的夹角，第一斜面1231的底端设置与所述进气槽125连通的进气口1232，第一斜面1231的顶端设置与所述出气管112连通的烟雾出口1233，且进气口1232和烟雾出口1233设置在雾化腔123的相对两侧，进气口1232沿第一斜面1231呈渐开状布置(由于第一斜面1231的存在，进气口1232的开口逐渐增大)，烟雾出口1233的底面高于进气口1232的顶面，烟雾出口1233的底面和进气口1232的顶面均大致位于第一斜面1231所在的平面内，使超声波雾化片上面形成从进气口1232到烟雾出口1233的倾斜向上的气流通道。
导油陶瓷21的底面将储油体22抵持在超声波雾化片32的雾化区域321，且超声波雾 化片32的雾化区域中心位置正好位于导油陶瓷21的下方。
为使超声波雾化片32超声振荡最为激烈的地方(雾化区域中心位置)不被导油陶瓷21覆盖，且保证雾化腔123内气流通道畅通，所述导油陶瓷21整体呈n型，且所述导油陶瓷21的底部中间设有过气通道211，所述过气通道211对应所述超声波雾化片32的雾化区域中心位置设置，从而避免导油陶瓷21影响超声波雾化片32中心位置的高频振荡雾化效果，使超声波雾化片32的超声雾化启动快，出烟快，产生的烟雾尽快达到最大化，同时使烟油雾化充分，避免用户吸食到烟油滴。
为避免导油陶瓷21的过气通道211的顶面影响气流倾斜向上流动的趋势，所述过气通道211的顶面设置为第二斜面214，且所述第一斜面1231与所述第二斜面214位于同一斜面上。
为使导油陶瓷21能尽快地传递烟油，保证超声雾化的烟油供应，所述导油陶瓷21的内部设置n型导油槽212，且所述导油槽212的上部与所述通油槽121对正，所述导油槽212的底部延伸到所述导油陶瓷21的底部；导油槽212的顶端与油仓13连通，导油槽212的下端为盲孔(有利于避免烟油大量地进入到储油体22)，油仓13的烟油通过通油槽121进入到导油槽212中，然后渗透到储油体22中。
为回收再利用超声波雾化片32在振荡过程中出现的飞溅烟油滴和烟雾中的大颗粒烟油滴，所述过气通道211的顶面设置用于回收烟油的回收槽213，且所述回收槽213与所述超声波雾化片32的雾化区域中心位置对应设置。
为避免产生困气现象，所述过气通道211的出口端与所述烟雾出口1233直接连通，使过气通道211内部的烟雾可通过烟雾出口1233直接排出。
为使烟油能迅速浸透至导油陶瓷21的四周，所述导油槽212的中部与所述回收槽213对应设置，且所述导油槽212的中部与所述回收槽213都设置于所述导油陶瓷21的中部。
本实施例超声波雾化器使用时，用户从本体1的吸嘴111处吸食，使得外部空气从进气槽125进入雾化腔123，烟油从油仓14经导油组件2传导到超声波雾化片32上，超声波雾化片32经雾化套31、电极组件35与外部电源电连接实现超声雾化，大部分进气气流被雾化腔123的顶面(第一斜面)引导倾斜向上流动到达烟雾出口，此过程中，大部分进气气流经过烟雾的末端，也就是将离超声波雾化片雾化区域表面比较远的烟雾带至烟雾出口，并经出气管及吸嘴排出，小部分进气气流经过烟雾的始端也就是雾化区域表面，使靠近雾化区域表面的含有大颗粒烟油滴的烟雾在靠近烟雾出口处撞击在雾化腔内壁上并凝结，在撞击的同时，少部分气流沿雾化腔内壁返回雾化腔内，使烟雾中含有的烟油滴再次参与超声雾化。
实施例2
实施例2与实施例1的不同之处在于导油组件2的不同。实施例2的导油组件2包括安 装在导油陶瓷固定槽122内的导油陶瓷21、固定安装在导油陶瓷21下部的储油体22和设置在导油陶瓷22与储油体22之间的弹簧23；为避免导油陶瓷21覆盖超声波雾化片32的雾化区域321影响雾化量，且保证雾化腔123内气流通道畅通，所述导油陶瓷21的底面与所述超声波雾化片32的雾化区域321相隔一距离。所述导油陶瓷21整体呈n型，且所述导油陶瓷21的内部设置n型导油槽212，导油槽212的底部贯穿所述导油陶瓷21的底部，使导油槽212的下段同时作为储油体固定槽215。所述储油体22为软性材质制成，比如可采用棉质材料制成，且所述储油体22包括固定段221、过渡段222和接触段223，固定段221位于储油体22的两端，接触段223位于储油体22的中部，过渡段222用于连接固定段221和接触段223，且固定段221插设固定在储油体固定槽215内，接触段223被弹簧23抵持在雾化芯3的超声波雾化片32的雾化区域321，并正好位于所述导油陶瓷21的下方；弹簧23的上端抵接于导油陶瓷21，弹簧23的下端抵接于接触段223。
烟油从油仓14可以经过储油体22的固定段221传导至接触段223并最终到达超声波雾化片32的雾化区域321，也可以经过导油陶瓷21传导到储油体22的接触段223并最终到达超声波雾化片32的雾化区域321。当储油体22的固定段221与储油体固定槽215配合过紧，不利于烟油和气体通过固定段221时，烟油和气体可以通过导油陶瓷21相互渗透，实现油仓13内烟油和气体置换，从而使烟油沿着储油体22和导油陶瓷21之间的空间顺利传导至超声波雾化片32上供给超声雾化形成烟雾，避免烟油量供给不足而产生干烧的现象，另外，由于导油陶瓷21的孔隙度是一定的，所以其渗透烟油和气体更加均匀，可以防止超声波雾化片32的雾化区域表面烟油过多而雾化不充分以及吸食到烟油滴的现象。
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。
