Description

一种电子烟雾化芯及雾化器 技术领域
本发明涉及电子烟具，具体涉及一种电子烟雾化芯及雾化器。
背景技术
现有的超声波雾化器中，外部空气从进气口进入到雾化腔都是通过一个进气道实现，并且气流的流速也不影响导油棉上的烟油流动，不同用户吸烟习惯不一样，有的急促吸烟，有的缓慢抽吸，因此导油棉传导到超声波雾化片上的烟油量有限，当用户急促抽吸时，导油棉供油不足，超声波雾化片容易出现干烧；当用户缓慢抽吸时，导油棉供油过剩，容易使超声波雾化片泡油或者使用户吸食到烟油滴。
发明内容
本发明所要解决的技术问题是，克服现有技术不足，提供一种能随进入雾化腔的气流大小自动调节导油棉下油量的电子烟雾化芯及雾化器。
为解决上述技术问题，本发明提供了一种电子烟雾化芯，包括相互套设的外套管和内套管，外套管上设置过油口，外套管的内腔中部设置超声波雾化片，内套管的内腔中部连接出气管，内套管的底部与超声波雾化片之间设置雾化腔，外套管与内套管之间套设连通所述过油口的导油棉，其中：
所述内套管的纵向间隔设置主气槽和辅气槽，所述辅气槽的横截面积是所述主气槽的横截面积的1/4-1/8，所述主气槽纵向贯通所述内套管，使主气槽与所述雾化腔相连通形成第一进气通道，所述辅气槽与所述导油棉相连通，且所述辅气槽的下端连通所述雾化腔，所述内套管的上部设置辅气入口，辅气入口与辅气槽之间设置辅气道，使辅气入口、辅气道、辅气槽、雾化腔相连通形成第二进气通道，第一、二进气通道共同构成外部空气进入通道。
当用户吸烟时，外界空气经过第一进气通道进入雾化腔并将超声雾化产生的烟雾经出气管带出，同时有一部分外界空气经辅气入口、辅气道、辅气槽及导油棉进入雾化器的油仓实现气体和烟油置换，使油仓内气压升高，烟油流出速度加快，进而使导油棉能吸收更多的烟油(由于超声波雾化片工作过程中消耗烟油，使得超声雾化过程中导油棉上的烟油处于未饱和状态，因此导油棉在烟油流速加快时可以吸收更多的烟油)，并为超声波雾化片工作过程提供足量烟油，防止超声波雾化片干烧；另外由于吸烟的作用，雾化腔的气压比外界气压低，经过第二进气通道的气流作用力与导油棉上烟油流动方向一致，因此可以使导油棉上的烟油传导速度更快，从而能防止导油棉上的烟油有气泡而阻碍导油速度，进一步避免超声波雾化片干烧的现象。当用户不吸烟时，即超声波雾化片的超声雾化停止，没有外界气流经过第二进气通道进入雾化腔时，导油棉上的烟油处于饱和状态，由于烟油粘度比较大，因此辅气道、 辅气槽可能被烟油滴堵住，从而可以减缓烟油流动，不会出现超声波雾化片被烟油浸泡的现象；当用户再次吸烟时，超声波雾化片将导油棉上饱和状态的烟油进行雾化，并利用经过第二进气通道的气流可以将堵在辅气槽和辅气道的烟油冲击到超声波雾化片上参与雾化，确保参与雾化的烟油足量。
进一步地，所述辅气道设置在与所述过油口对应的位置，这样进入的气体与油仓距离近，气体穿过导油棉进入油仓能更快实现气体和烟油置换。
进一步地，所述主气槽设置在所述内套管的外壁上，且所述主气槽与所述导油棉错开设置，使主气槽经过的主气流不影响导油棉上的烟油流速，避免导油棉上烟油流动速度过快而使超声波雾化片雾化烟油不充分或泡油。
进一步地，所述辅气入口为倒锥台状，以便于气体顺畅地进入辅气入口。
进一步地，所述内套管的下部设置与所述雾化腔一体设置的第三腔体，且第三腔体为锥台状，因此，超声波雾化片超声雾化时飞溅的烟油会被第三腔体的倾斜内壁遮挡，从而防止飞溅起来的烟油滴被出气管内的气流带出而被用户吸食。
进一步地，所述内套管的外周纵向对称设置导向槽，所述导油棉的两端经导向槽包覆在所述内套管上，且所述导向槽内设置所述辅气槽。这样，在组装导油棉时，导油棉沿导向槽的纵向方向组装，能有效防止导油棉歪斜而影响其导油效果。
所述第三腔体内设置弹簧，所述弹簧的一端将所述导油棉抵持在所述超声波雾化片上形成雾化区。
基于同一构思，本发明提供了一种电子烟雾化器，其包括上述的电子烟雾化芯。
进一步地，所述雾化器还包括相互连接的吸嘴装置和油仓装置，所述吸嘴装置上设置吸嘴和进气口，所述油仓装置的中部设置所述雾化芯，且所述油仓装置的出油口连通所述雾化芯的过油口，所述吸嘴的底部连通出气管，所述出气管的底部经所述内套管伸入所述雾化腔中，使雾化腔、出气管的内腔及吸嘴相连通形成烟雾排出通道。
本发明雾化器将进气流分为两股进入到雾化腔内，主气流通过主气槽进入雾化腔带走烟雾，辅气流通过辅气道、辅气槽与导油棉接触既可以实现气体与油仓内烟油快速置换又可以辅助导油棉上烟油流动的动力。同时导油棉与油仓的出油口连通即导油棉吸收烟油并且将烟油传导到超声波雾化片上表面雾化成烟雾。当用户肺活量大，吸烟速度快时，经过辅气道、辅气槽的气流速度也比较快，从而气体透过导油棉进入到油仓内与烟油置换速度快，同时辅气流动力辅助导油棉上烟油流动，因此增加导油棉的导油量，避免烟油供给超声波雾化片雾化不足而产生干烧或烟雾量比较小现象；当用户肺活量小，吸烟速度慢时，经过辅气槽的气流速度也比较慢，从而气体透过导油棉进入到油仓内与烟油置换速度慢，甚至辅气流动力无 法冲击掉辅气槽内的烟油滴即辅气流不能辅助导油棉上烟油流动，因此减少导油棉的导油量，避免烟油供给超声波雾化片雾化过多而产生被烟油浸泡或或雾化不充分而吸食到烟油的现象。

雾化芯4包括外套管42，外套管42上设置与出油口221相对的过油口421。外套管42的内腔从上至下依次设置内套管43、弹簧44、导油棉45、超声波雾化片46及电极组件47，内套管43的底部与超声波雾化片46之间形成雾化腔41。内套管43的外周对称设置主气槽431和导向槽432，且主气槽431的一端与进气口12相连通，另一端与雾化腔41相连通，导向槽432朝向出油口221设置，且导向槽432内设置连通雾化腔41和出油口221的辅气槽4321。内套管43的内腔上部设置倒锥台状的第一腔体433，中部设置用于连接出气管3的圆柱状的第二腔体434，下部设置锥台状的第三腔体435。出气管3经第一腔体433插入第二腔体434中并与第二腔体434固定连接，且第一腔体433与出气管3的外壁之间形成辅气入口436，辅气入口436与辅气槽4321之间设置辅气道437，出气管3的底部伸入雾化腔41内。这样，进气口12经主气槽431连通雾化腔41形成雾化腔41的第一进气通道，进气口12经辅气入口436、辅气道437、辅气槽4321连通雾化腔41形成雾化腔41的第二进气通道，第一、二进气通道共同构成外部空气进入通道。
超声波雾化片46设置在硅胶套48上，导油棉45经内套管43的导向槽432包覆在内套管43上，并被外套管42夹持，且导油棉45朝向出油口221设置，第三腔体435内设置弹簧44，弹簧44的下端将导油棉45抵顶在超声波雾化片46上形成雾化区。
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。
