Description

雾化器及其电子烟 技术领域
本发明涉及模拟吸烟技术领域，特别涉及一种雾化器及其电子烟。
背景技术
电子烟又名为虚拟香烟、电子雾化器、电子雪茄烟，有着与香烟一样的外观，与香烟近似的味道，主要是用于模拟吸烟的感觉，以供戒烟或香烟替代使用。
雾化器是电子烟的重要组成部分。目前市场上的雾化器在雾化室内设置加热电阻丝，电阻丝内部再设置导液纤维材料例如纤维棉，通过导液纤维材料与烟液储存室连通，其主要是利用纤维导液材料来导液，这些纤维材料在加热状态下容易焦化、干烧并产生异味，而且热效率低，浪费电量，同时纤维材料也属于易耗物品，增加了使用成本。现有技术中也出现了取消导液纤维材料的尝试，其试图通过加压装置将烟液喷入雾化室，以代替纤维导液材料的导液功能，但是这种方式需要添加增压装置，造成了产品结构的复杂，使用不太可靠，如果采用较为强力的增压方式的话，还会带来使用安全的问题。
发明内容
基于此，有必要针对上述问题，提供一种使用安全可靠，没有焦化和干烧现象，不会产生异味的雾化器及其电子烟。
一种雾化器，包括壳体、收容于壳体内的雾化组件和烟液袋，壳体内设有一级雾化通道，烟液袋开设有与所述一级雾化通道连通的出液口，雾化组件具有二级雾化元件，二级雾化元件设置有与一级雾化通道连通的二级雾化空间，二级雾化元件的上部设有出气孔，经过二级雾化空间雾化形成的气溶胶在气流作用下从出气孔流出，烟液袋受到空气压力使得烟液从出液口流出并在一级雾化通道内与空气混合后进入二级雾化空间进行雾化。
进一步地，壳体的一端装设有进气件，壳体包括外壳、内壳和底板，所述 内壳的内部构成容纳雾化组件的雾化内腔，所述外壳、内壳和底板共同构成容纳烟液袋的烟弹腔，烟弹腔包围在雾化内腔的周围。内壳的底壁上设置有壳体支撑部，壳体支撑部上开设一级雾化通道。底板上设有向下突出的凹陷部,在凹陷部上设有压力平衡通道，压力平衡通道可操作的与烟弹腔和/或进气件的内部连通。
进一步地，压力平衡通道上安设通气阀。通气阀包括通气塞和阻尼元件，所述通气塞包括设于烟弹腔内的密封端部和设于进气件内的抵接端部，阻尼元件设于底板和抵接端部之间。
进一步地，在底板上安装遮罩件，所述遮罩件容纳伸入烟弹腔内的通气塞的密封端部，遮罩件容纳密封端部的空间与烟弹腔连通。
进一步地，进气件具有与一级雾化通道连通的进气内腔，进气内腔外周的侧壁上开设有进气口。所述进气内腔顶部与所述一级雾化通道底部连通，进气内腔的截面积大于一级雾化通道的截面积。
进一步地，在烟液袋和内壳的外壁之间设有隔温件。
进一步地，所述烟液袋具有出液端，出液端上设置有出液口。
可选地，所述二级雾化元件的结构形状为腔体/片状/球状/网状。
可选地，所述二级雾化元件为不锈钢/陶瓷发热体。
进一步地，烟液袋为在大气压和重力作用下可自由形变的软质烟液袋。
进一步地，还包括电极组件，电极组件具有与壳体连接的负极套筒、安装在负极套筒内的绝缘圈和安装在绝缘圈内的正极接触件。负极套筒和正极接触件分别通过负极引线和正极引线与二级雾化元件电连接。
一种电子烟，所述电子烟包括前述任一项的雾化器。
本发明的雾化器，不需要设置烟液加压装置，简化了产品结构，使用更安全可靠。由于不需要导液纤维材料，降低使用时的成本消耗，也没有焦化和干烧现象，不会产生异味，同时也能有效避免未雾化的烟油炸油。由于烟液在进入雾化内腔之前已经被打散成微小液滴，且在雾化内腔内受热面积大，因此所需雾化温度低且雾化充分，雾化效率高，热效率高，电池得到充分利用，节省了电量，也延长了产品使用寿命。

实施例一
请参阅图1-5，本发明实施例一提供了一种雾化器，包括壳体1、进气件2、雾化组件3、烟液袋4、烟嘴5和电极组件6。进气件2和烟嘴5分别装设于壳体1的两端，雾化组件3设置在壳体1的内部并位于进气件2的上方，烟液袋4设置在雾化组件3的周围，且烟液袋4收容于壳体1内，电极组件6安装于进气件2的一端。
请参考图2，壳体1大致呈两端具有开口的筒体状，包括外壳10、内壳11和底板12，所述内壳11的内部构成容纳雾化组件3的雾化内腔13，所述外壳10的内壁、内壳11的外壁和底板12共同构成容纳烟液袋4的烟弹腔14。在烟液袋4和内壳11的外壁之间设有隔温件15，隔温件15阻止雾化内腔13内的高温向烟弹腔14内传递。
内壳11的底壁上设置有壳体支撑部16，壳体支撑部16中心圆孔中安装有壳体支撑件17。壳体支撑部16上围绕壳体支撑件17开设有一级雾化通道203。在本实施例中，一级雾化通道203为围绕壳体支撑件17设置的对称的两个圆孔，可以理解，此处的一级雾化通道203的形状不限定于圆孔，还可以为矩形通孔等，其数量也可以为一个、两个或两个以上。
如图4和图5所示，底板12上设有向下突出的凹陷部121,在凹陷部121 上设有穿过底板12的透气圆孔以构成压力平衡通道204，压力平衡通道204连通烟弹腔14和进气件2的内部。
在本实施例中，凹陷部121设置了一个，在底板12上呈环状向下突出，可以理解，凹陷部121可以设置不止一个，也不限定于环状，其可以为其它任何连续或断续的形状。
底板12的凹陷部121的压力平衡通道204上安装有通气阀40，通气阀40包括通气塞41和阻尼元件42。通气塞41包括设于烟弹腔14内的密封端部411和设于进气件2内的抵接端部412，阻尼元件42设于底板12和抵接端部412之间。
在底板12上还设有遮罩件43，所述遮罩件43用于容纳伸入烟弹腔14内的通气塞41的密封端部411，遮罩件43容纳密封端部411的空间与烟弹腔14连通。
相应地，可以理解，压力平衡通道204及通气阀40和遮罩件43也可以设置一个或多个。
本实施方式中，阻尼元件42为安装在底板12和抵接端部412之间的弹簧，可以理解的，该弹簧的数量不做限定，可以围绕压力平衡通道204设置多个，例如在压力平衡通道204的左右位置各设置一个弹簧以防止通气塞41影响正常运作。阻尼元件42也可以套设于通气塞41上，阻尼元件42一端弹性抵持底板12，阻尼元件42的另一端弹性抵持抵接端部412。
阻尼元件42的种类也不做限定，只要具有弹性和刚性的元件或者其组合，都在本发明的保护范围之内。
如图2和图3所示，进气件2设置在壳体1的下部，大致呈两端封闭的圆筒状，具有与压力平衡通道204连通的进气内腔21，进气内腔21外周的侧壁上开设有进气口22。进气内腔21顶部与一级雾化通道203底部连通，进气内腔21的截面积大于一级雾化通道203的截面积。
雾化组件3设置在壳体1的内壳11内并位于进气件2的上方，所述雾化组件3具有二级雾化元件30，二级雾化元件30设置在雾化内腔13内，二级雾化元件30由不锈钢板制成，本发明实施方式中，二级雾化元件30为中空结构， 二级雾化元件30内部形成二级雾化空间31，二级雾化元件30的上部开设有出气孔301，用于将经过两级雾化的气溶胶通过。
本实施方式中，二级雾化元件30为空心结构，其由可通电发热的不锈钢薄片构成。可以理解，二级雾化元件30也可以为可通电发热的其他材料例如陶瓷片构成，也不限定于图示结构，也可以为片状、网状或球状等其他结构，只要能够使得将烟液在加热情况下雾化均可。
烟液袋4设置在壳体1的烟弹腔14内并大致包围在雾化组件3的周围，烟液袋4下方具有出液端404，出液端404的末端开设有与所述一级雾化通道203连通的出液口403，所述出液端404至所述出液口403的截面积逐渐变小。在本实施例中，出液口403为围绕壳体支撑件17设置的对称的两个直孔，可以理解，此处的出液口403的形状不限定于直孔，其数量也不限定于两个，可以为一个或多个。
烟液袋4为在大气压和重力作用下可自由形变的非弹性软质烟液袋，烟液存放于非弹性的软质烟液袋内，烟液袋4随烟液减少在大气压和重力的作用下产生形变，使得烟液所受到的压力等于大气压力。压力平衡通道204便于烟液在正常大气压和重力的作用下从出液口403流出。烟液袋4限定为非弹性的，因为烟液袋4具有弹性时，烟液袋4及其内腔中的烟液除了受到自身的重力和大气压力作用外还存在弹力的作用，烟液袋4易于在弹力的作用下收缩，导致烟液容易发生泄露，且烟液袋4内外重力和大气压达不到平衡，实现不了一级雾化。
烟嘴5设置在壳体1的上方，烟嘴5开设有烟嘴通道51，二级雾化空间31和烟嘴通道51经由出气孔301连通。
电极组件6设置在壳体1的下方，包括与壳体1连接的负极套筒61，安装在负极套筒61内的绝缘圈62，以及安装在绝缘圈62内的正极接触件63。负极套筒61和正极接触件63分别通过引线与二级雾化元件30电连接以使二级雾化元件30可以通电发热。
在本发明中，当用户进行抽吸时，气流经由进气口22进入进气内腔21，将出液口403流出的的烟液与空气混合，进入二级雾化空间31，在经过二级雾化 元件30雾化后，从出气孔301流出，经过烟嘴供用户吸入。在气流流动过程中，烟弹腔14内的气压大于进气内腔21内的气压，烟液袋4在大气压力下将烟液从出液口403中喷出，以完成一级雾化。经过一级雾化后形成的雾状烟液与空气混合，进入二级雾化空间31进行雾化，以形成气溶胶供用户吸食。
随着烟液的不断消耗，进气内腔21的气压大于烟弹腔14内的气压，使得烟液很难从从出液口403中流出。此时，当用户不进行抽吸时，由于进气内腔21的气压大于烟弹腔14内的气压，气体压力作用在通气阀40的抵接端部412上，克服阻尼元件42的弹力，使通气塞41向上升起，从而打开通气阀，气体通过压力平衡通道204进入烟弹腔14，使得烟弹腔14和进气内腔21之前的气压一致。在上述气压一致后，通气塞41在阻尼换件42的弹力作用下复位，通气阀40关闭。此后，当用户再次进行抽吸时，烟液袋4在大气压力下，能够再次将烟液从出液口403中喷出，以进行一级雾化形成雾状烟液与空气混合，再进入二级雾化空间31进行雾化，已形成气溶胶供用户吸食。
软质烟液袋4内的烟液在大气压力和重力的作用下，从烟液袋4底部的出液口403流出。此时进入进气内腔21内的气体同时通过一级雾化通道203进入二级雾化空间31。
所述进气内腔21远大于所述一级雾化通道203截面积，所述进气内腔21顶部与所述一级雾化通道203底部连通。当使用者抽吸时，气体从进气口22进入进气内腔21内，而此时烟液从底部的出液口403流出到达一级雾化通道203，由于单位时间内的流量不变，在截面积骤然减小的情况下，流速增大，从而形成高速气流，而此时一级雾化通道203内的压强小于烟液袋4内的压强，烟液喷出，在高速气流和压强的作用下形成雾状的微小液滴，实现一级雾化。
该微小液滴在气流的带动下，通过一级雾化通道203进入二级雾化空间31，设置在此处的二级雾化元件30亦即本实施例中的二级雾化元件30一端与正极相连，一端与负极相连，通过电能转化成热量，将烟液进一步进行二级雾化。
二级雾化元件30顶部设有出气孔301，既增加了液滴在二级雾化元件30内的雾化时间，使其充分雾化，又可使气流和雾化后的气溶胶从二级雾化空间31进入烟嘴通道51。
在烟液袋4和内壳11的外壁之间设置的隔温件15，用来隔热烟液袋4和二级雾化元件30，避免在加热雾化二级雾化元件30内的气溶胶时导致烟液袋4内的烟液也被加热。
可以理解的，本实施例中的进气件2也可以通过其他多种已公开的技术方案实现，例如CN201610024931.4已经公开的在雾化器的进气件的外周设置有调气环，调气环设置有调气孔，调节调气环与雾化器进气件的相对位置，可以调节调气孔与通气孔的连通面积，进而能够调节进入雾化器之中的空气量，从而可以调节产生的烟雾量以精确调节。
本实施例的雾化器，不需要设置烟液加压装置，使用更安全可靠。由于不需要导液纤维材料，降低使用时的成本消耗，也没有焦化和干烧现象，不会产生异味，同时也能有效避免未雾化的烟液炸油。由于烟液在进入雾化内腔之前已经被打散成微小液滴，且在雾化内腔内受热面积大，因此所需雾化温度低且雾化充分，雾化效率高，热效率高，电池得到充分利用，节省了电量，也延长了产品使用寿命。
实施例二
请参阅图6和图7，本发明实施例二的雾化器与实施例一的雾化器的区别在于，在内壳11的内壁和二级雾化元件30的外壁之间设有固定件103，所述的固定件103为与内壳11的内壁和二级雾化元件30外壁的形状相吻合的硅胶塞。同时，电极组件6的负极套筒61和正极接触件63分别通过负极引线611和正极引线631与二级雾化元件30连接。
可以理解的，本实施例中的固定件103可以为硅胶塞，也可以为其它任何能够实现固定功能的固定材料或其组合，其结构形状也不限于图示结构，可以根据设计需要在本发明的基础上进行合理的变形。
本实施例的雾化器，进一步优选了实施方式，由于设置了固定件103，可以确保二级雾化元件31稳定可靠使用，同时通过引线方式将电极组件6与二级雾化元件30连接，简便可靠，在充分满足使用性能的同时简化产品结构，降低产品成本。
上述实施例仅表达了本发明的实施方式，其描述较为具体和详细，但并不 能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
