Description

一种超声波电子烟雾化芯及雾化器 技术领域
本发明属于电子烟领域，特别涉及一种超声波电子烟雾化芯及雾化器。
背景技术
现有的高频超声波电子烟雾化芯具有以下缺点：
第一，导油棉为平放的片状结构，导油棉整片紧贴在雾化片表面，因此，导油棉与雾化片的接触面积的大，雾化启动时间长需等待数十秒才能雾化。
第二，导油棉及雾化片均架设在硅胶座上，依靠轴向挤压硅胶座间接挤压导油棉来控制导油棉的松紧度，进而控制导油棉的导油速率，该种方式有可能造成雾化片挤压过紧，影响振荡效果。
第三，由于进油孔直接垂直向下开设于导油棉之上，因此进油孔与雾化片距离较近，当雾化片温度升高时，烟油流动性变强，烟油导油速率很快，无法很好地控制导油塑料，容易造成泡油现象，导致雾化片难以雾化烟油。
第四，由于雾化芯套管为单层管壁结构，因此热量极易传递至外层的雾化器外管，导致雾化器外管发烫现象较严重。
发明内容
本发明的目的在于，针对上述现有技术的不足，提供一种改进了的超声波电子烟雾化芯及雾化器，雾化启动速度快、雾化片振荡效果好、导油速率稳定性好、导油速率可控性强、雾化器外管不易发烫，同时还可避免吸食大颗粒烟雾，且雾化芯更换方便。
为解决上述技术问题，本发明所采用的技术方案是：
一种超声波电子烟雾化芯，包括雾化芯套管，该雾化芯套管内的导油棉和雾化片，所述导油棉的底面与雾化片的顶面相接触，所述导油棉上对应雾化片中心的位置开设第一通孔。
导油棉上对应雾化片中心的位置开设第一通孔，可以有效地提高雾化速度，原因是雾化片中心位置无导油棉阻挡，可即时雾化烟油，瞬间产生烟雾，可很好地改善泡油及雾化启动速度问题。
进一步地，所述雾化芯套管包括雾化芯内套管和套设在该雾化芯内套管外的雾化芯外套管，所述导油棉为开口向上的杯状结构，所述导油棉的侧壁夹设在雾化芯内套管和雾化芯外套管之间。
借由上述结构，由于雾化芯内套管和雾化芯外套管之间的窄缝对导油棉侧壁有一定的挤压作用，因此可以通过挤压雾化芯内套管和雾化芯外套管控制导油棉的松紧度，进而控制该导油路径的导油速率。只需控制杯状导油棉侧壁的体积，即可很好地控制导油棉侧壁的松紧度，从而可很好地控制导油速率。
进一步地，所述导油棉底面上还开设至少一个第二通孔。
第二通孔为烟雾进口，其设置可以将烟雾快速地输送到吸嘴供用户吸食。
进一步地，所述导油棉的侧壁与底部交界区域周向均布开设通气槽，导油棉底部未开通气槽区域与雾化片接触连接。
该方案中，导油棉底部被分割成多个细小的导油细条，导油细条与雾化片接触能够更加充分的雾化，而且与外界进入的空气混合更充分。
进一步地，所述导油棉的底面为向下凸起的圆弧面，所述圆弧面与雾化片的中心位置接触。
借由上述结构，导油棉与雾化片为中心局部小面积接触，热量可以集中在小面积接触处，避免流失，可以在很大程度上提高雾化片的雾化速度，即按下开关，即可很快产生烟雾。
进一步地，所述雾化芯外套管上开有与导油棉相通的进油孔。
借由上述结构，进油孔与雾化片有一定距离，因此进油孔处的温度不会太高，且温度相对稳定，从而该处烟油流动速率比较稳定、导油速率相对比较稳定，可很好地控制导油棉的导油速率，解决泡油问题。
进一步地，所述雾化芯内套管外侧壁上对应导油棉的位置开设至少一个凹槽。
凹槽可以减少组装时雾化芯内套管外侧壁和导油棉接触产生的摩擦力，从而组装方便；同时由于对应凹槽位置的导油棉不受挤压，因而导油棉导油速度相对较快；再者，凹槽也可缓存一定量的烟油，从而可即时补充雾化消耗的烟油，避免供油不足。
进一步地，还包括弹性支架，所述雾化芯内套管的内侧壁上开设台阶，所述弹性支架的顶端卡在台阶处，弹性支架的另一端与导油棉内底面相挤压。
弹性支架挤压导油棉内底面，可防止吸烟时将导油棉往上吸而脱离雾化片表面，造成导油棉与雾化片接触不良。
基于同一个发明构思，本发明还提供了一种超声波电子烟雾化器，包括雾化器外管，所述雾化器外管内设有所述的超声波电子烟雾化芯。
由于雾化芯与整个雾化器外管中间有多层管壁间接导热，在一定程度上降低了热量的传导，使雾化器外管在发烫问题上有一定的改善。
进一步地，还包括通气管、第一连接座、气流挡板和吸嘴，所述吸嘴底部侧壁上开设进气孔，所述吸嘴底端与雾化器外管的侧壁顶端相连，所述通 气管的底端深入雾化芯套管内，通气管的顶端通过第一连接座与气流挡板相连，所述气流挡板水平置于吸嘴内；所述气流挡板上沿周向开有至少一个第三通孔；所述进气孔、通气管、第三通孔均与吸嘴相通。
吸嘴处设有气流挡板，气流先冲撞气流挡板，后拐弯进入人体口腔，可以很好地避免吸食大颗粒烟雾。
作为一种优选方式，所述吸嘴底端通过上端盖与雾化器外管的侧壁顶端相连，雾化器外管的侧壁底端通过下端盖与底座相连；所述雾化芯的顶端与上端盖相插接，所述雾化芯的底端与底座相螺接。
借由上述结构，可直接手动拆卸雾化芯，更换非常方便。
与现有技术相比，本发明雾化启动速度快、雾化片振荡效果好、导油速率稳定性好、导油速率可控性强、雾化器外管不易发烫，同时还可避免吸食大颗粒烟雾，且雾化芯更换方便。
