实施该发明的最佳实施例
本发明的最佳实施方式
本发明下面将结合附图作进一步详述：
本发明采用超声波雾化单元的电子烟雾化器，为便于以下行文描述，如图1所示将该电子烟雾化器的吸嘴朝上竖直放置，下文所述有关其部件的“上端、下端”，均是指在该电子烟雾化器竖直放置情况下的上下方向和位置关系。
如图1、图2所示，本发明实施例采用超声波雾化单元的电子烟雾化器，包括上端带吸嘴11和下端开口的外管1，外管1内自上而下向依次设有储液杯2、多孔支 撑片3、烟液渗透片4、压紧片5、超声波雾化单元6、雾化座7、电源连接座8；雾化座7上端的端面通过贴紧压紧片5后将烟液渗透片4压紧在多孔支撑片3上，雾化座7的下端与电源连接座8连接，电源连接座8套接在外管1下端的内壁。
如图1、图2、图3所示，储液杯2的上端封闭和下端开口，储液杯2用于储存电子烟烟液。多孔支撑片3横向固定在储液杯2下端开口处的内壁上，多孔支撑片3为设有多个小通孔的硬片，其上下两面所在的储液杯内壁上设有可以夹住多孔支撑片3的凸点或凸环(图中未示)以便对其固定。多孔支撑片3上设有若干小通孔以便电子烟烟液从储液杯2中缓慢流出，多孔支撑片3同时对烟液渗透片4起到固定支撑的作用。烟液渗透片4紧贴于多孔支撑片3上，其一般由具有多孔隙、能缓慢渗透的材料制成，在用户吸烟时，雾化座7内产生负压可使储液杯2内的电子烟烟液通过烟液渗透片4渗透出来，而用户不吸烟时，储液杯2内外压力平衡，烟液渗透片4可阻止烟液从储液杯2内漏出。
如图1、图2、图3所示，储液杯2在下端侧壁部设有矩形缺口21，储液杯2的外表面在与矩形缺口21相同的周向位置轴向设有一道烟雾槽22，多孔支撑片3、烟液渗透片4横置于储液杯2的矩形缺口21位置以上的内壁，烟液渗透片4下平面与矩形缺口21的上沿相平。雾化座7的上端套设于储液杯2在矩形缺口21位置的内壁，雾化座7的烟雾出口正对储液杯2的矩形缺口21重合设置，这样经超声波雾化单元6雾化的电子烟雾即可经烟雾出口71(矩形缺口21)排出，再经烟雾槽22与外管1的内壁围合而成的电子烟出雾通道，最后从吸嘴11的吸口111流出至用户口中。
如图1、图3、图4所示，压紧片5呈工字形并可恰好放入储液杯2的下端开口内，其上下两边为外凸的圆弧段，下边还设有垂直的片状凸起51。本发明的烟液渗透片4，当其吸纳饱满了电子烟烟液时，重力增加，在重力作用下，软性的烟液渗透片4容易偏离多孔支撑片3，发生松脱，这样电子烟烟液就容易从储液杯2内发生泄漏。为此设有压紧片5，在雾化座7的上端端面压紧下，压紧片5可将烟液渗透片4压紧在多孔支撑片3上，这样烟液渗透片4就不会发生松脱，避免了电子烟烟液从储液杯2内泄漏出来。本发明的压紧片5，可采用薄不锈钢钢片制成，以减少厚度提高支撑刚性。
如图5、图6、图7所示，雾化座7为侧壁部开设有烟雾出口71的管状体、内置超声波雾化单元6，超声波雾化单元6包括导液条61、雾化片62和超声波震荡片63，导液条61两端分别连接烟液渗透片4和雾化片62，超声波震荡片63可将自烟液渗透片4、导液条5传导至雾化片62的电子烟烟液进行超声波雾化。雾化座7的内部设有底壁72，底壁72的中间设有进气通孔73，底壁72上自进气通孔73向烟雾出口71对面的方向设有进气凹槽74，进气凹槽74延续到雾化座7的内侧壁上，雾化座7的底壁72上还设有向下的穿线孔721供超声波震荡片63的两个电极引线631穿过。超声波震荡片63设于底壁72的上面，雾化片62设于超声波震荡片63的上面，导液条61有两条设于烟液渗透片4和雾化片62之间并与两者抵触连接，其作用是可将烟液渗透片4中的烟液传导至雾化片62。
本发明的烟液渗透片4和雾化片62由陶瓷纤维制成，导液条61由陶瓷纤维、玻璃纤维或硬体多孔陶瓷材料制成，用以更好地吸纳、传导、储存电子烟烟液。雾化座7由硅胶材料制成，软性的硅胶材料起到减震和密封的作用。
如图5、图6所示，雾化座7还包括其上端所设的雾化座盖75，雾化座盖75上开设有与导液条61位置相对应的盖孔751，导液条61穿过盖孔751。雾化座盖75用于定位、固定导液条61以及使雾化座7不易发生变形。
如图1、图8所示，电源连接座8包括一端设有环形凸肩810的管体81，管体81另一端内壁套接电极座82，电极座82的外国设有螺纹820，电极座82内设有一道径向阻隔环821，阻隔环821的中间通孔套设有绝缘套83，绝缘套83内套设有钉形电极84，钉形电极84的中间设有电极通孔841。超声波震荡片63的两个电极分别和钉形电极84及电极座82电性连接，并进一步和电子烟电源的正负极电连接。
如图1、图3、图6、图8所示，本发明的实施例，当雾化器工作时，储液杯2内装有的电子烟烟液经多孔支撑片3的小通孔流出至烟液渗透片4，烟液渗透片4充满烟液时，可将烟液传导给导液条61，再经导液条61传导给雾化片62，雾化片62上吸纳电子烟烟液时，经超声波震荡片63通电工作即可将烟液进行雾化；此时外界空气自钉状电极84的电极通孔841流入，再经进气通孔73、进气凹槽74流入到雾化座7内的雾化片62之上的雾化空间，产生的电子烟烟雾，即可经烟雾出口71(矩形缺口21)排出，再经烟雾槽22与外管1的内壁围合而成的电子烟出雾通道 ，最后从吸嘴11的吸口111流出并被用户吸入口中。
发明实施例
本发明的实施方式
实施例二
本实施例二在上述实施例一的基础上，对雾化单元进行改动，在导液条上加设有加温用的电热丝，其余结构不变。
如图9所示，导液条61上加设有加温用的电热丝64，该电热丝64工作时仅可对流经导液条上的电子烟烟液进行加温。由于不同种类的电子烟烟液具有不同的粘度，在粘度较大时，超声波震荡片63对该电子烟烟液的雾化效果就可能降低，因此在导液条61上设有加温用的电热丝64，这样即可对流经导液条61的电子烟烟液进行加温，当电子烟烟液传导至雾化片62时，因其粘度已降低，即可提高超声波震荡片63对其的雾化效果。因本实施例二的电热丝64仅用于加温，故其对电热丝的要求可以较细、较短，对通电电流要求也较小，其加温时不会使电子烟烟液雾化。
如图10所示，本实施例的导液条61为一圆柱体，采用多孔易渗透的陶瓷材料制成，外面缠绕电热丝64，电热丝62两端连接引线641，导液条61的中心轴线上设有一导液通孔610，其上端端面上沿直径设有一道导液凹槽611，电热丝64缠绕于导液条61的外壁，与电热丝64上端线头相连的引线641设于导液凹槽611内并穿过导液通孔610向下引出，另一引线641则位于导液条61的外壁向下引出。
实施例三
本实施例三在上述实施例一的基础上，对雾化单元进行改动，在导液条上加设有加热雾化用的电热丝，其余结构不变。
如图11所示，导液条61上加设有加热雾化用的电热丝65，该电热丝65工作时可对流经导液条61的部分电子烟烟液进行雾化，另一部分电子烟烟液传导至雾化片62，以便超声波震荡片63对其进行雾化。本实施例三设定电热丝65和超声波震荡片63在用户吸烟时同时工作，因此可以大大提高一次吸烟时产生的烟雾量，提升用户吸烟的口感。与实施例二不同的是，因本实施例三的电热丝65用于加热雾化，故其对电热丝的要求应当较粗、较长，对通电电流要求也较大，其 加热时应使部分电子烟烟液雾化。
如图12所示，本实施例的导液条61为一圆柱体，采用多孔易渗透的陶瓷材料制成，其中心轴线上设有一导液通孔610，其上端端面上沿直径设有一道导液凹槽611，电热丝65缠绕于导液条61的内部并与其融合制成为一体，电热丝65的引线651露出于导液条61并向下引出。导液通孔610与导液凹槽611可以通气及更好地传导烟液。
工业实用性
以上所述仅为本发明的较佳实施例，凡依本发明权利要求范围所做的均等变化与修饰，皆应属本发明权利要求的涵盖范围。
