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，特别是一种电子烟雾化芯及雾化器。
背景技术
现有超声波电子烟中，在连续抽吸几口烟雾时雾化器的超声波雾化片容易出现被烟油浸泡或干烧现象，从而导致烟雾量变小，烟雾口感差，且连续多次干烧后，超声波雾化片的使用寿命缩短，不仅增加了使用成本，而且用户体验感差。
另外，现有超声波雾化器的超声波雾化片包括压电陶瓷基体和在压电陶瓷基体的上、下表面分别设置的上表面电极和下表面电极，当电源的两极分别接通上表面电极和下表面电极时即可使压电陶瓷基体产生高频振荡，使烟油在压电陶瓷基体的表面雾化成烟雾。但，在使用超声波雾化片雾化烟油时，超声波雾化片在雾化电路中相当于一个电容，所以在电路断路后超声波雾化片所承载的能量无处释放，在再次接通电路时超声波雾化片瞬间释放高能量到主板的各个元器件上，因此容易将元器件烧掉，比如MOS管被高电压击穿，从而影响电路的正常工作，不仅增加了使用成本，而且使用户体验差。
超声波雾化器中超声波雾化片的侧面没有被卡设固定，很容易出现晃动或移动，进而容易产生电连接不良的现象，同时组装使用过程中超声波雾化片容易偏移或翘起，使得烟油在超声波雾化片表面上分布不均匀，容易产生干烧的现象。
发明内容
本发明要解决的技术问题是，克服现有技术的不足，提供一种导油顺畅，且导油速度均匀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，包括雾化棉安装座、雾化棉和超声波雾化片，所述雾化棉安装座的中部设置雾化腔，所述超声波雾化片包括上表面电极和下表面电极，所述上表面电极与外电极连接，所述下表面电极与内电极连接，所述雾化棉安装座的上表面设置连通成一体的第一空槽和第二空槽，第一空槽的顶部设置出气开口，所述出气开口对应油仓装置的出油口设置，第一空槽和第二空槽靠近所述雾化腔的一端分别设置进气开口，第一空槽经其进气开口连通第二空槽，第二空槽的进气开口连通雾化腔，且第一空槽的进气开口小于第二空槽的进气开口。
由于第一空槽通过其进气开口与第二空槽连通，并且第一空槽的进气开口小于第二空槽的进气开口，使第一、二空槽整体形成设置在雾化腔一侧的喇叭状开口，当第一空槽积有烟油时，烟油可以随着喇叭状开口从第二空槽流出，因此不仅可防止第一空槽被烟油滴堵住而影响出油口的气体置换，而且雾化腔内的气体可经第二空槽进入第一空槽，然后从第一空槽 顶部的出气开口透过雾化棉，再从油仓装置的出油口进入到油仓内，使油仓内气压升高，油仓内烟油导出更加顺畅，进而使雾化棉导油顺畅，导油速度均匀，超声波雾化片雾化烟油的效果更好，不至出现超声波雾化片干烧现象；另外，第一空槽的进气开口小于第二空槽的进气开口，可避免过量的空气进入到第一空槽以及油仓内，从而避免在不吸烟时从油仓内导出的烟油量过多而浸泡超声波雾化片导致的超声波雾化片对烟油的雾化效率降低，并加大了用户吸食到烟油的风险。
进一步地，所述第一空槽外侧的所述雾化棉安装座上设置有第一固定槽，所述雾化棉的端部覆盖在第一空槽和第二空槽上，并延伸到所述第一固定槽内，所述雾化棉的中部与所述超声波雾化片的雾化区域接触，并使第一空槽和第二空槽对应的雾化棉始终呈悬空状态，从而使导油时，烟油受到的阻力小，导油更加顺畅。
进一步地，所述外电极与内电极之间卡设电阻板，电阻板上设置电阻，所述电阻的一端经所述外电极与所述超声波雾化片的上表面电极电连接，所述电阻的另一端经所述内电极与所述超声波雾化片的下表面电极电连接。这样，本发明通过将电阻板卡接在外电极与内电极之间，不仅使雾化器在断电后，超声波雾化片与电阻板上的电阻形成一个闭合电路，从而消耗超声波雾化片在通电又断开后自身存储的能量，从而使得超声波雾化片再次通电后能够正常工作，避免超声波雾化片再次通电后释放瞬时高电压而烧坏其他电子元器件，降低使用成本，由于电阻板卡接在外电极与内电极之间，因而电阻板的组装简单、方便、快捷，安装稳定，使雾化器的制作成本相应降低。
进一步地，所述内电极包括一电极座，所述电极座上设置卡柱，所述卡柱的顶部设置凸台，所述电阻板上设置一便于将电阻板插入电极座的插入口，所述插入口内设置便于电阻板与所述卡柱及凸台卡合的卡住口，所述电阻板经插入口套设在所述电极座上，并经卡住口与所述电极座的卡柱及凸台卡设固定。这样，组装时，电阻板通过其插入口插进电极座内，然后推动电阻板使电阻板的卡住口卡在电极座的卡柱上，并与凸台抵接，就可使电阻板被稳定卡住，并使电极座与电阻板形成电路接通，不需要再另外通过螺丝固定，从而使组装简单，制造成本降低。
进一步地，所述卡住口的开口与所述卡柱的外形匹配，使电阻板与电极座组装更加稳定。
进一步地，所述外电极的下部置入衔接电极，所述衔接电极的中部设置让位槽，所述让位槽上设置凸起的顶持台，所述电阻板的下表面放置在所述顶持台上，且所述电阻板的上表面与所述电极座的凸台相抵持。这样，在电阻板在插入电极座后，在将电阻板的卡住口移动卡住电极座的卡柱及凸台过程中，让位槽不与电阻板接触，使得电阻板移动的过程中摩擦力减小，更加省力，组装更为方便。
进一步地，所述超声波雾化片安装在雾化座上，且所述雾化座上设置有用于固定所述超声波雾化片的第二固定槽和限位环，从而可有效阻挡超声波雾化片的掉出或者移动，避免由于超声波雾化片组装不稳定而造成超声波雾化片倾斜及与烟油接触不充分而产生干烧的现象，提高组装后超声波雾化片的稳定性。
进一步地，所述雾化座外周套设所述外电极，所述外电极的上端跨过所述雾化座的顶面并设置向下弯折的抵持部，所述抵持部上设置外凸的导电环，所述外电极通过导电环抵持在所述超声波雾化片的上表面电极上实现电连接。这样，外电极与超声波雾化片的电连接不需要焊接电子线，从而使得雾化芯组装方便，电性连接稳定。
进一步地，所述雾化座的底部设置插入端，所述雾化座通过其插入端插入衔接电极的顶部并固定安装在所述衔接电极上，从而不仅使雾化座与衔接电极连接稳定，而且使雾化芯组装方便快捷，成本低。
进一步地，所述雾化棉安装座的上表面对称设置有第一固定槽，所述雾化棉的两端分别插设在所述第一固定槽内，并覆盖在第一空槽和第二空槽上，从而使雾化棉被更为稳定地安装在雾化棉安装座上。
进一步地，所述第一固定槽、第一空槽、第二空槽从外至内依次设置在所述雾化棉安装座的上表面。
基于同一发明构思，本发明还提供了一种电子烟雾化器，其包括所述电子烟雾化芯，所述油仓装置的下表面与所述雾化棉安装座的上表面抵接，使所述雾化棉的两端被所述油仓装置与所述雾化棉安装座夹紧，所述雾化腔位于所述油仓装置下表面与所述超声波雾化片的上表面之间，所述雾化腔与外部空气连通，且所述第一空槽的出气开口大于所述出油口。
这样，不仅雾化腔内的气体可经第二空槽进入第一空槽，并透过雾化棉而从出油口进入到油仓内，使油仓内烟油与气体的置换更加顺畅，从而保证了烟油从油仓流出的流速，进而使超声波雾化片雾化烟油的效果更好，不至出现超声波雾化片干烧现象，而且第一空槽的出气开口大于所述出油口，可防止第一空槽被烟油滴堵住而影响出油口的气体置换。。
另外，本发明雾化棉的两端覆盖过第一空槽和第二空槽后，雾化棉两端的两侧均被雾化棉安装座的顶部端面抵接在油仓外壳的出油口端面上，雾化棉两端的两侧顶接处由于被抵压太紧而无法导流烟油，所以雾化棉的导流烟油部分仅为第一空槽和第二空槽对应的位置，使烟油的流量得到控制，从而不会出现超声波雾化片被烟油浸泡的现象，同时也可以防止雾化棉掉进第一空槽或第二空槽内而影响油仓内烟油和气体置换速度比较慢而引起导油速度慢，进而使超声波雾化片出现干烧现象。
进一步地，所述油仓装置由油仓内壳和油仓外壳相互卡合形成，所述油仓外壳上设置所 述出油口。
进一步地，所述油仓装置中部设置旋柄，所述旋柄的顶端套设吸嘴装置，且吸嘴装置可相对旋柄转动，从而打开或关闭油仓装置的注油口。所述吸嘴装置上设置吸嘴和进气口，所述旋柄中部设置与所述吸嘴和雾化腔连通的出气通道，所述旋柄的外周设置与所述进气口和雾化腔连通的进气通道，从而为雾化器提供了完整的气流途径。

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，本发明电子烟雾化器一实施例包括吸嘴装置1、油仓装置3和雾化芯4。吸嘴装置1上设置吸嘴11和进气口12。油仓装置3由油仓内壳31和油仓外壳32相互卡合形成油仓，油仓的底部设置出油口321。油仓装置3的上面罩设压盖2，油仓装置3的下面套设底盖5。雾化芯4经底盖5插入油仓外壳32内，并使油仓外壳32的下表面中部与雾化芯4的上表面相抵接。
雾化芯4包括雾化棉41、雾化棉安装座42、超声波雾化片43、雾化座44、外电极45、电阻板46、衔接电极47、绝缘环48、内电极49。
雾化棉安装座42的上表面从外到内对称设置第一固定槽421、第一空槽422和第二空槽423，第一空槽422与第二空槽423相连通，且第一空槽422正对油仓装置3的出油口321设置，第一空槽422的出气开口大于出油口321，优选为出油口321口径的两倍，以防止第一空槽422被烟油堵塞而影响出油口321的气体置换；第一空槽422的进气开口小于第二空槽423的进气开口，保证了第一空槽422不容易被烟油堵住。雾化棉安装座42优选采用硅胶套。
雾化座44的内腔上部设置有第二固定槽441和限位环442，雾化座44的下部设置插入端443。雾化座44通过其插入端443插入衔接电极47的内腔，使雾化座44稳定放置在衔接电极47的顶部。超声波雾化片43嵌套在雾化座44的第二固定槽441内并被限位环442抵顶限位，从而可有效阻挡超声波雾化片43从雾化座44掉出或者在其中移动，进而有效避免由于超声波雾化片组装不稳定而造成的超声波雾化片倾斜及其与烟油接触不充分而产生干烧的现象，提高组装后超声波雾化片的稳定性。
雾化棉41的两端覆盖在第一空槽422和第二空槽423上后，其末端插设在第一固定槽421内，且雾化棉41的中部在弹簧7的作用下下凹，并与水平放置在雾化座44内的超声波雾化片43接触形成雾化区，同时使第一空槽422和第二空槽423对应的雾化棉41呈悬空状态。超声波雾化片43的上表面与油仓外壳32的下表面之间形成雾化腔，第二空槽423的进气开口与雾化腔连通，第一空槽422正对油仓装置3的出油口321设置，因而雾化腔内的气体可经第二空槽423、第一空槽422、出油口321进入到油仓内进行烟油和气体置换，从而保证了烟油的流速。雾化棉41的两端覆盖过第一空槽422和第二空槽423后，雾化棉41的两侧均被雾化棉安装座42的顶部端面抵接在油仓外壳32的出油口端面上，雾化棉41的两侧顶接处由于被抵压太紧而无法导流烟油，所以雾化棉41的导流烟油部分仅为第一空槽422和第二空槽423对应的位置，从而使烟油的流量得到控制，不会出现超声波雾化片43被烟油浸泡的现象，同时也可以防止雾化棉41掉进第一空槽422或第二空槽423内而影响油仓内烟油和气体置换速度比较慢而引起导油速度慢，进而使超声波雾化片43出现干烧现象。
雾化棉安装座42的下面连接外电极45，外电极45的上部套设在雾化座44上，以利用外电极45保护雾化座44，防止雾化座44变形而影响雾化座44内的超声波雾化片43的形态。外电极45的上端跨过雾化座44的顶面并设置向下弯折的抵持部451，该抵持部451上设置外凸的导电环452，外电极45通过导电环452抵持在超声波雾化片43的上表面电极上实现电连接。外电极45的下部连接衔接电极47，衔接电极47的中部设置让位槽471，让位槽471的内侧设置凸起的顶持台472。超声波雾化片43的下表面电极与内电极49连接。内电极49包括电极座491，电极座491的中部设置与超声波雾化片43的下表面电极抵接的弹性电极492。内电极49安装在衔接电极47的内腔，且衔接电极47与内电极49之间设置绝缘环48。电极座491上设置卡柱4912和凸台4911，电阻板46上设置插入口461和卡住口462，且插入口461与卡住口462相连，电阻板46经插入口461套设在电极座491的卡柱4912上，并经卡住口462与凸台4911卡设固定，同时与衔接电极47的顶持台472相抵持，从而实现电阻板46上的电阻与衔接电极47、内电极49的电连接，使电阻的两端分别与超声波雾化片43的上、下表面电极连接，从而使超声波雾化片43与电阻之间形成一个闭合电路，这样，通过电阻可消耗超声波雾化片43自身存储的能量，从而使得超声波雾化片43再次通电后能够正常工作，避免雾化器主板上的元器件受到极大电压冲击而受损，延长其寿命，降低实用成本。
油仓装置3的中部设置旋柄6，旋柄6的顶端套设吸嘴装置1，且吸嘴装置1可绕旋柄6旋转，从而可将油仓装置3的进油口封闭或打开。旋柄6的中部设置与吸嘴11和雾化腔连通的出气通道61，旋柄6的外周设置与进气口12和雾化腔连通的进气通道62。
本发明使用时，吸烟者从吸嘴11处进行抽吸，使外部空气从进气口12进入，经进气通道62进入雾化腔，烟油从油仓的出油口321流到雾化棉41上，并经第一、二空槽对应的雾化棉41处流到与超声波雾化片43接触的雾化棉中部，经超声雾化后，经出气通道61流到吸嘴11而被吸烟者吸食。
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。
