Description

电子烟及其雾化器
本申请要求于 2015 年 10 月 22 日提交的中国发明专利申请 201510690956.3 （名称为电子烟及其雾化组件和雾化元件）和 2015 年 11 月 27 日提交的中国发明专利申请 201510854348.1 （名称为电子烟及其雾化组件和雾化元件）的优先权，将其全部内容整体并入本文。
【技术领域】
本发明涉及烟具的技术领域，特别是涉及一种电子烟及其雾化器。
【背景技术】
电子烟又名虚拟香烟、电子雾化器。电子烟具有与香烟相似的外观和味道，但一般不含香烟中的焦油、悬浮微粒等有害成分。
雾化组件作为电子烟产生雾化气体的核心装置，其雾化效果决定了烟雾的质量与口感。一般的雾化组件的加热体为螺旋状的发热丝，发热丝缠绕在一吸液芯上。当发热丝通电时，存储在吸液芯上的烟液，经发热丝的加热作用雾化，产生烟雾。
然而，上述电子烟在使用过程中，由于发热丝呈线状，只能对位于发热丝附近的烟液加热使其雾化，而离发热丝较远的烟液，螺旋状的发热丝空隙处的烟液，不容易被雾化，另外，随着与发热丝距离的增大，温度会大幅下降，因此，烟液的雾化温度不均，导致烟液的雾化颗粒大小不一，雾化效果较差。
【发明内容】
基于此，有必要提供一种雾化效果更好的电子烟及其雾化器。
一种电子烟的雾化器，包括:
本体，所述本体内部开设有相隔离的气流通道和储液腔；以及
雾化元件，包括多孔体和多孔发热膜；所述多孔体包括雾化面和吸液面；所述雾化面为平面，且与所述气流通道中的气体流动方向基本平行，所述多孔发热膜形成于所述雾化面上；所述吸液面能够吸取所述储液腔内的所述烟液。
一种电子烟，包括电池装置和所述的雾化器，所述电池装置和所述雾化器电连接并为所述雾化器供电。
上述电子烟及其雾化器，多孔体即能够封堵住烟液，又能保障导液效果。多孔发热膜用于将多孔体内的烟液雾化，多孔发热膜上的微孔，能够大大增加与烟液的接触面积，提高雾化效率。多孔发热膜位于多孔体的雾化面上，便于雾化后的烟液从多孔体中跑出。雾化面为平面，从而便于形成均匀的多孔发热膜。多孔发热膜能够使多孔体的表面均匀的受热，因此雾化作用的温度是均匀一致的，不会出现局部温度低导致的雾化颗粒较大的问题，保证了雾化颗粒均匀。雾化面与气流通道中的气体流动方向基本平行，从而更加便于气流掠过雾化面，带走汽化的烟液。上述电子烟及其雾化器的雾化效果好，提高了电子烟的口感。

【具体实施方式】
为了便于理解本发明，下面将参照相关附图对电子雾化装置进行更全面的描述。附图中给出了电子雾化装置的首选实施例。但是，电子雾化装置可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对电子雾化装置的公开内容更加透彻全面。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在电子雾化装置的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“及／或”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1、图2所示，一实施方式的电子烟包括雾化器10和电池装置20，电池装置20和雾化器10电连接并为雾化器10供电。其中，雾化器10包括本体100和雾化元件200，本体100内部开设有气流通道102和用于存储烟液的储液腔104，气流通道102和储液腔104相隔离。同时参见图3、图4，雾化元件200包括多孔体120和多孔发热膜（图中未示出）。多孔体120包括雾化面122和吸液面124。雾化面122为平面，且与气流通道102中的气体流动方向基本平行，多孔发热膜形成于雾化面122上。吸液面124能够吸取储液腔104内的烟液。具体的，在一实施例中，雾化面122的数量为两个，两个雾化面122相对设置。及/或吸液面124的数量为两个，两个吸液面124相对设置。雾化面122、吸液面124相对的设置两个，可以提高雾化、吸液的效率。
多孔体120即能够封堵住烟液，又能保障导液效果。多孔发热膜用于将多孔体120内的烟液雾化，多孔发热膜上的微孔，能够大大增加与烟液的接触面积，提高雾化效率。多孔发热膜位于多孔体120的雾化面122上，便于雾化后的烟液从多孔体120中跑出。雾化面122为平面，从而便于形成均匀的多孔发热膜。多孔发热膜能够使多孔体120的表面均匀的受热，因此雾化作用的温度是均匀一致的，不会出现局部温度低导致的雾化颗粒较大的问题，保证了雾化颗粒均匀。雾化面122与气流通道102中的气体流动方向基本平行，从而更加便于气流掠过雾化面122，带走汽化的烟液。上述电子烟及其雾化器10的雾化效果好，提高了电子烟的口感。
参见图3、图5，在其中一个实施例中，本体100包括储液器140和雾化芯160，储液腔104位于储液器140内，雾化芯160设置在储液腔104中。雾化元件200和气流通道102均位于雾化芯160内，雾化芯160上开设有连通孔，吸液面124位于连通孔处，吸液面124通过连通孔吸取储液腔104内的烟液。
同时参见图2、图6，进一步的，在一实施例中，雾化芯160包括外管162、内管164和密封垫圈166，外管162套设在内管164外部，外管162和内管164之间形成进气通道106。雾化元件200和气流通道102均位于内管164内。进气通道106与气流通道102的一端连通。具体的，在一实施例中，可以在内管164上开设用于通气的孔165，实现进气通道106与气流通道102的连通。外管162、内管164、雾化元件200三者套接，即可方便的形成进气通道106和气流通道102，方便生产加工，可以降低成本。
连通孔包括第一连通孔162a和第二连通孔164a，第一连通孔162a位于外管162，第二连通孔164a位于内管164，第一连通孔162a和第二连通孔164a相对应，密封垫圈166位于内管164和外管162之间，且密封垫圈166环绕第一连通孔162a和/或第二连通孔164a处，使进气通道106相对于第一连通孔162a和第二连通孔164a隔离。同时，由于密封垫圈166具有一定的柔性，可以使内管164和外管162之间的连接更加可靠。密封垫圈166可以是橡胶或硅胶材质，密封较高较佳。
同时参见图4、图6，在其中一个实施例中，多孔体120可以包括一体连接的主体部126和凸出部128，雾化面122位于主体部126上，吸液面124位于凸出部128上，且吸液面124相对远离主体部126。内管164的侧壁上开设有卡接槽164b，凸出部128卡接在卡接槽164b内，至少部分卡接槽164b形成第二连通孔164a，密封垫圈166环绕凸出部128。安装多孔体120时，可以直接将凸出部128卡入卡接槽164b，同时即可形成连通孔，方便安装，简化加工过程。
同时参见图2、图7，在其中一个实施例中，本体100还可以包括烟嘴180和连接套190。烟嘴180包括嘴部182和遮挡部184，嘴部182开设有出气通道108，出气通道108与气流通道102的另一端连通。遮挡部184与嘴部182固定连接，遮挡部184上开设有调节口184a。连接套190与外管162连接，且连接套190套设在烟嘴180上，与烟嘴180转动连接。连接套190开设有连通进气通道106的进气口192，遮挡部184能够遮挡进气口192，调节口184a与进气口192相对应，转动烟嘴180能够调节调节口184a与进气口192的重合面积。
本实施例的电子烟，可以通过旋转烟嘴180调节气流量，具体的，遮挡部184能够遮挡进气口192，调节口184a与进气口192相对应，转动烟嘴180能够调节调节口184a与进气口192的重合面积，从而可以调节气流量。通过烟嘴180调节气流量，可以省略掉传统的气流调节组件中的转动环，结构简单，可以降低电子烟的成本。
具体的，在一实施例中，进气口192为沿连接套190的圆周方向延伸的长条孔，可以增加转动烟嘴180能够调节的气流量的范围。在一实施例中，调节口184a为由遮挡部184的远离嘴部182的边缘向嘴部182开设的缺口，进一步的简化结构，方便加工，减低生产成本。
烟嘴180还可以包括连接部186，连接部186位于嘴部182和遮挡部184之间，连接套190套接在连接部186上，烟嘴180通过连接部186与连接套190转动连接。再参见图6，在一实施例中，雾化芯160还可以包括连接管168，连接管168套设在外管162的外部，连接管168的一端连接储液器140，连接管168的另一端连接连接套190。在一实施例中，雾化芯160还包括接气管169，接气管169的一端连接内管164，接气管169的另一端连接烟嘴180。设置连接管168和接气管169，方便加工和组装，有利于提高连接的可靠性。
再参见图3，在其中一个实施例中，多孔发热膜上的微孔的孔径小于多孔体120上的微孔的孔径。电子烟中的雾化面122位于气流通道102中，多孔体120直接与空气接触，多孔体120具有相对较大直径的微孔，因此，电子烟在存放过程中，烟液更加容易泄露。而本实施例中，因为多孔体120表面形成有孔径相对更小的多孔发热膜，多孔发热膜在电子烟存放过程中可以减小烟液的泄露程度。
在其中一个实施例中，多孔体120上的微孔的孔径为1μm至100μm。较佳地，多孔体120上的孔径为5μm至30μm的微孔的体积，占多孔体120上的所有微孔体积的60%以上。多孔体120使烟液不会快速的流到多孔发热膜的一侧，此为封堵作用，与此同时，多孔体120使烟液相对缓慢的渗透至于多孔发热膜接触处，此为导液作用。本实施例中，多孔体120的封堵作用的效果和导液作用的效果俱佳。封堵作用佳可以防止多孔体120漏液，导液作用佳可以确保不会发生干烧。
在一实施例中，多孔体120的孔隙率为30%至83%，孔隙率是指多孔介质内的微小空隙的总体积与该多孔介质的总体积的比值。孔隙率的大小可以根据烟液的成分来调整，例如烟液的粘稠度大的，孔隙率则可以高一些，以保证导液效果。
进一步的，在一实施例中，多孔发热膜的材质为金属，更进一步的，在一实施例中，多孔发热膜的材质为钛、镍、镍铬中的一种。多孔发热膜的厚度为0.5μm至1.5μm，较佳地，多孔发热膜的厚度为0.8μm至1μm，多孔发热膜的上的微孔的孔径为5μm至30μm。
多孔发热膜可以通过气相沉积法形成在多孔体120上，可以确保多孔发热膜具有一定的厚度，也能确保多孔发热膜为多孔的形态。由于多孔体120的主要微孔孔径大于多孔发热膜的厚度，因此，在通过气相沉积法在多孔体120上沉积薄膜时不会封堵住多孔体120上的微孔，从而直接形成多孔发热膜。具体的，在一实施例中，气相沉积法包括化学气相沉积法和物理气相沉积法，其中物理气相沉积法包括蒸镀、溅镀。
本实施例中，多孔体120可以是多孔陶瓷，多孔陶瓷化学性质稳定，不会与烟液发生化学反应，多孔陶瓷能够耐高温，不会受到多孔发热膜发热的影响，且多孔陶瓷为绝缘体，不会与多孔发热膜电连接，方便制造、成本低。在其他实施例中，多孔体120也可以是多孔玻璃、多孔塑料、多孔金属或者其他可形成多孔结构的材质。若多孔体120为多孔塑料等耐温较低的材质，可在多孔体120上形成多孔发热膜前，先形成隔热材料层。若多孔体120为多孔金属等导电材质，可在多孔体120上形成多孔发热膜前，先形成绝缘层，例如，对多孔金属的表面进行氧化处理等。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，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。
