技术领域
本申请涉及电子烟技术领域，尤其涉及一种雾化器。
背景技术
电子烟是一种模仿卷烟的电子产品，电子烟不含焦油，且具有便携、美观等优点而受到欢迎。相关电子烟包括雾化器，雾化器用于将烟油在雾化芯的加热作用下雾化蒸发，以生成可供吸收的雾化蒸汽，即“烟雾”，通过雾化蒸汽使得用户获得吸烟的刺激感。相关的雾化器产生的雾化蒸汽较多，加热的雾化蒸汽易于与雾化器内设置的气流通道的壁面接触从而形成冷凝液，导致用户在吸入雾化蒸汽时体验感不佳。
发明内容
有鉴于此，本申请提供一种雾化器，以解决如何减少雾化过程中冷凝液产生的技术问题。
本申请的技术方案是这样实现的：
本申请实施例提供一种雾化器，包括：底座；导液片，用于吸收液体；雾化芯，与所述底座分别设置在所述导液片的相对两侧，所述雾化芯加热以雾化所述液体；罩体，包覆所述雾化芯的端部并抵压所述雾化芯与所述导液片接触；其中，所述雾化器具有气流通道，所述气流通道贯穿所述底 座、所述导液片和所述罩体，且所述雾化芯至少部分位于所述气流通道内。

上述方案中，所述气流通道沿第一方向延伸，所述抵压部包覆所述雾化芯在第二方向上的端部，所述液体通道在所述第二方向上位于所述气流通道的外侧，所述第一方向垂直于所述第二方向。

上述方案中，所述抵压部的内表面呈台阶状，所述内表面包括第一表面和位于第一表面的外侧的第二表面，所述第二表面与所述雾化芯抵接，所述第一表面与所述雾化芯之间具有间隔空间，所述气流通道贯穿所述间隔空间。
上述方案中，所述底座包括：座体；凸起，突出于所述座体；其中，所述导液片套设在所述凸起外侧且与所述座体抵接。
上述方案中，所述凸起设置为环状，以与所述座体上表面围成第二空腔；其中，所述座体开设用于导线通过的通孔，所述气流通道和所述通孔间隔设置且均与所述第二空腔连通。
上述方案中，所述雾化芯包括：芯体，所述芯体的边缘与所述导液片的外边缘间隔预定距离；发热件，环绕所述芯体设置，所述发热件至少部分位于所述气流通道内；所述发热件与所述导线连接。
上述方案中，所述雾化器还包括：外壳，套设在所述罩体外侧，所述气流通道贯穿所述外壳；其中，所述外壳内具有储液部，所述储液部与所 述液体通道连通以输出所述液体。
上述方案中，所述雾化器还包括：底壳，用于容纳所述底座，所述底壳与所述罩体固定以封装所述底座、所述导液片和所述雾化芯；其中，所述气流通道贯穿所述底壳。
本申请实施例提供的一种雾化器，包括底座、导液片、雾化芯和罩体，导液片用于吸收液体，雾化芯与底座分别设置在导液片的相对两侧，雾化芯加热以雾化液体，罩体包覆雾化芯的端部并抵压雾化芯与导液片接触，并且雾化芯至少部分位于气流通道内。本申请实施例通过将雾化芯和底座分别设置在导液片的相对两侧，罩体包覆雾化芯的端部并抵压雾化芯，使得雾化芯与导液片接触，从而雾化芯只能从与导液片接触的方向吸油，减慢了雾化芯的吸油速度，进而使得烟油被雾化生成蒸汽的速度较慢，生成的蒸汽能够被用户快速吸出而减少了与气流通道的壁面接触产生冷凝液的可能性。本申请实施例有利于减慢雾化芯吸收烟油的速度，从而减少冷凝液的产生，使得用户吸入的雾化蒸汽细腻均匀，具有良好的使用体验感。

本申请实施例提供一种雾化器。雾化器用于电子烟，是电子烟的主要组成结构，电子烟根据用户是否能够自主添加烟油的方式可以包括换弹电 子烟和可注油电子烟；换弹电子烟预先在雾化器中注好烟油，并将储油仓封闭，使用完用户无需自己灌油，只要更换厂家提供的专属烟弹即可；可注油电子烟为用户在使用时可自主向储油仓添加烟油。本申请实施例以雾化器应用于可注油电子烟为例进行说明，本领域技术人员可以理解，本申请实施例的雾化器也可以应用于换弹电子烟。
如图1所示，本申请实施例提供的一种雾化器10，包括底座1、导液片2、雾化芯3和罩体4。为了方便结合图对雾化器10进行说明，以下提到的上下左右方向为图1示出的雾化器放置状态下的上下左右方向，可以理解，以下提到的上下左右方向并不限定是实际使用情况下的上下左右方向。导液片2用于吸收液体，例如，液体可以是烟油。雾化芯3与底座1分别设置在导液片2的相对两侧，底座1位于导液片2的下方，用于支撑导液片2，雾化芯3位于导液片2的上方，与导液片2接触。其中，底座1可以与套设在其外侧的外壳7抵接，并且底座1的密封性能良好，从而液体不容易通过底座1渗透到底座1的下方，例如，底座1的材料可以是硅胶，硅胶具有良好的密封性能。雾化芯3设置在导液片2的上表面，与导液片2接触，雾化芯3用于加热导液片2吸收的液体，使得液体受热蒸发从而产生雾化蒸汽。雾化芯3仅与导液片2的一个表面接触，接触面积相对较小，因此雾化芯3从导液片2上吸收液体的速度较慢，对应的加热液体得到雾化后的蒸汽的速度较慢。罩体4包覆雾化芯3的端部，因此对雾化芯3的端部进行隔离保护，使得液体不会直接流到雾化芯3。并且，罩体4从上方抵压雾化芯3，使得雾化芯3与导液片2更好地接触，即从上向下施加压力在雾化芯3上，使得雾化芯3稳定的和下方的导液片2接触，而不容易发生偏移，通过罩体4对雾化芯3端部的包覆以及在上方的抵压，进一步的增加了雾化芯3只能从下方的导液片2吸收液体的稳定性。如图1所示，雾化器10具有气流通道5，其中，气流通道5并不是仅存在雾化器 10的某个部件中，气流通道5贯穿底座1、导液片2和罩体4，使得气体可通过底座1、导液片2和罩体4。气流通道5贯穿雾化器10的方向为上下方向，在使用时，气流的流向从底座1到罩体4，对应的，经过罩体4的气体可以是空气和液体雾化后形成的蒸汽，而经过底座1、导液片2的气体可以是空气，由于雾化芯3设置在导液片2上方，气流方向由下向上，并且底座也具有良好的密封作用，因此液体雾化后形成的蒸汽不会向下渗透。并且，雾化芯3至少部分位于气流通道5内，在用户使用时，空气被吸入经底座1、导液片2再到雾化芯3，即：空气从下往上吹向导液片2和雾化芯3，带动液体雾化后形成的蒸汽通过罩体4再到吸嘴72中。
本申请实施例通过将雾化芯和底座分别设置在导液片的相对两侧，罩体包覆雾化芯的端部并抵压雾化芯，使得雾化芯与导液片接触，从而雾化芯只能从与导液片接触的方向吸油，减慢了雾化芯的吸油速度，进而使得烟油被雾化生成蒸汽的速度较慢，生成的蒸汽能够被用户快速吸出而减少了与气流通道的壁面接触产生冷凝液的可能性。本申请实施例有利于减慢雾化芯吸收烟油的速度，从而减少冷凝液的产生，使得用户吸入的雾化蒸汽细腻均匀，具有良好的使用体验感。
在一些实施例中，图2示意了从图1所示上下方向的从下向上看的角度下的罩体4的立体结构示意图，图3示意了沿着雾化器的对称面剖面的剖视图，图4示意了图3所示A区域的放大图，图3和图4中的实线箭头为液体流动方向，虚线箭头为气流流动方向。如图2所示，罩体4包括第一外壳41和抵压部42。其中，第一外壳41内部中空，内部形成第一空腔411。抵压部42设置在第一空腔411内且与第一外壳41固定连接，抵压部42包覆雾化芯3的端部以抵压雾化芯3，以使得雾化芯3能稳定通过下部的表面与下方的导液片2接触，气流通道5贯穿抵压部42且与第一空腔411连通，气流可经过气流通道5而穿过罩体4。其中，抵压部42与第一外壳 41之间形成液体通道43，使得液体可通过液体通道43流入罩体4内的第一空腔411，液体的流向如图3和图4所示的实线箭头方向，例如，液体通道43可以是环绕抵压部42设置一圈，也可以是在抵压部42的一侧或两侧分布，只要导液片2与液体通道43连通可吸收液体即可。导液片2可以是导油棉片，也可以是其他可用于吸收、传导的纤维、玻璃、陶瓷或包含以上任一种的复合材质。导液片2设置在雾化芯3的下方并与雾化芯3接触，并且导液片2部分位于液体通道43内与液体接触并吸收传导液体给雾化芯3，雾化芯3的材质可以与导液片2相同或不同，只要是可用于吸收、传导的纤维、玻璃、陶瓷或以上的复合材质即可。本申请实施例通过设置液体通道43，导液片2可吸收传导通过液体通道43流入的液体给雾化芯3，从而雾化芯3加热从导液片2吸收的液体，使得液体受热蒸发从而产生雾化蒸汽。
在一些实施例中，如图3和图4所示，气流通道5沿第一方向延伸，第一方向如图3所示的L1方向，其中，第一方向是指雾化器10在正常使用状态下气流的方向，可以理解为是图1所示的上下方向，可以理解，气流通道5的延伸方向可以是与雾化器的轴线方向一致，雾化器整体可以为轴对称结构，具有轴线。气流通道5的两端均与外界连通，雾化器10在正常使用状态时，液体加热后的雾化蒸汽可通过气流通道5进入吸嘴，并且空气可加快液体的雾化，从而带动液体雾化后形成的蒸汽通过气流通道5到吸嘴中。如图4所示，抵压部42包覆雾化芯3在第二方向上的端部，抵压部42对雾化芯3的包覆使得雾化芯3与液体通道43隔离开来，第二方向如图3所示的L2方向，第一方向垂直于第二方向。液体通道43在第二方向上位于气流通道5的外侧，通过导液片2和雾化芯3连通液体通道43和气流通道5，具体的，如图3所示，导液片2沿第二方向设置，雾化芯3沿第二方向设置在导液片2的上方，气流通道5沿第一方向延伸且位于抵 压部42的中间区域，从而液体先经液体通道43向下流向到导液片2，然后导液片2吸收液体并沿第二方向传导到导液片2靠近中部的区域，同时，导液片2吸收了液体的区域将吸收的液体传导到与导液片2接触的雾化芯3，气流通道5沿第一方向设置在抵压部42的中间区域，通过气流通道5内的气流运动可以加速液体雾化蒸发以及引导雾化后的蒸汽沿气流通道5向上流动。本申请实施例通过设置液体通道在两侧，而气流通道在中间，从而引导液体的流向，使得液体容易朝向气流通道设置的方向流动，从而提升液体的利用效率以及减少液体向非气流通道方向渗漏的可能性。
在一些实施例中，如图2和图4所示，抵压部42设置凹槽421。凹槽421用于容纳雾化芯3，凹槽421的尺寸与雾化芯3的尺寸相匹配，例如，凹槽421的长度、宽度和高度对应与雾化芯3的长度、宽度和高度基本相同，使得雾化芯3不至于在凹槽421内过于晃动。如图2所示，抵压部42具有与凹槽421相邻的侧壁422，侧壁422位于凹槽421的第二方向的外侧，侧壁422分隔凹槽421与液体通道43，使得从液体通道43流下的液体不会直接流入凹槽421，而必须先流到凹槽421下侧的导液片2，液体只能经导液片2流向雾化芯3，从而减少液体不经导液片2而直接流向雾化芯3所造成了雾化芯吸收液体速度过快的问题。本申请实施例通过设置凹槽，使得雾化芯可容纳于凹槽内而不与液体通道43直接接触，使得雾化芯只能从下方的导油片上吸油，从而减慢吸油速度，降低了雾化器内产生冷凝液的可能性。
在一些实施例中，如图4所示，抵压部42的内表面423呈台阶状，抵压部的内表面可以理解为靠近抵压部的轴线的表面，抵压部42的内表面423并不是平面，而是第二方向上靠近中间区域的内表面更高，从而形成凹槽421。内表面423表示位于侧壁422以内的抵压部42的表面，内表面423包括第一表面4231和位于第一表面4231的外侧的第二表面4232。第二表 面4232形成凹槽421，凹槽421用于容纳雾化芯3并抵压雾化芯3。第一表面4231与雾化芯3之间具有间隔空间4233，间隔空间4233在圆周方向的尺寸是大于气流通道5的，气流通道5贯穿间隔空间4233，液体经雾化芯3加热雾化后的蒸汽可在间隔空间4233内充分混合后再经气流通道5吸入到吸嘴中。本申请实施例通过在雾化芯3的上侧设置间隔空间4233，使得雾化蒸汽可在间隔空间4233内充分混合。
可以理解，在一些实施例中，位于侧壁422以内的抵压部42的内表面423也可以基本是平面，即内表面423到导液片2的高度基本是相同的，该高度可以是雾化芯3的高度，那么间隔空间4233可以不存在。在另一些实施例中，位于侧壁422以内的抵压部42的内表面423也可以是弧面而不存在台阶。通过将抵压部42的内表面423设置为各种形状可以满足雾化器的小型化、加工方便等多种不同需求。
在一些实施例中，图5示意出了放置状态下底座和导液片以及雾化芯的设置方式示意图。如图5所示，底座1包括座体11和凸起12。凸起12突出于座体11。其中，导液片2套设在凸起12外侧且与座体11抵接，例如，凸起12的高度是略小于或等于导液片2的厚度的，导液片2套设在凸起12外侧后，雾化芯3可以与导液片2贴合并较好地接触。如图1所示，外壳7可以套设在底座1的外侧，座体11与外壳7的内壁贴合几乎没有缝隙，并且底座1具有良好的密封性能，使得液体较难渗入到底座1的下方。本申请实施例通过设置在底座1上设置凸起12，有利于导液片2的定位和安装。
在一些实施例中，如图5所示，凸起12设置为环状，导液片2可环绕设置在凸起12的外侧，并且凸起12与座体11的上表面围成第二空腔13，第二空腔13内部中空。座体11开设用于导线6通过的通孔14，通孔14在第二方向上设置在第二空腔13的范围内。如图1所示，导线6穿过通孔14 与设置在座体11下侧的电极81连接，电极81可嵌入底壳8，底壳8对电极81起到安装和固定的作用。气流通道5贯穿座体11，气流通道5和通孔14间隔设置且均与第二空腔13连通，可以理解，气流通道5和通孔14间隔设置表示二者在第二方向是没有连通，那么导线不会设置在气流通道5内影响气流流动以及美观性。本申请实施例通过设置凸起12为环状，使得导线6与气流通道5均设置在环状凸起12的第二空腔13内，环状结构的凸起12在起到方便导液片嵌套定位之外也起到了收纳导线的作用。
在一些实施例中，如图1和图5所示，雾化芯3包括芯体31和发热件32。其中，芯体31与导液片2接触，且在第二方向上，芯体31的边缘与导液片2的外边缘间隔预定距离，芯体31的边缘伸入液体通道43预定距离与液体接触，使得导液片2能够较好地控制液体的吸收量。发热件32与导线6电连接，导线6与用于提供电能的电极81连接，电极81嵌入在底壳8内，从而发热件32将电能转化成热能，使芯体31发热从而雾化所吸收的液体。发热件32环绕芯体31设置，使得芯体31能够充分加热，发热件32至少部分位于气流通道5内，使得发热件32处受热蒸发的蒸汽通过气流通道5传导至吸嘴中。本申请实施例通过设置环绕芯体31的发热件32，有利于雾化芯3整体的均匀发热，使得产生的蒸汽整体上均匀，有利于提高用户的体验感。
在一些实施例中，如图1所示，雾化器10还包括外壳7。外壳7套设在罩体4外侧，气流通道5贯穿外壳7，液体蒸发后的蒸汽可输出到外壳7的外侧；其中，外壳7内具有储液部71，储液部71位于罩体4上方，储液部71与液体通道43连通以输出液体。罩体4的上方设置密封盖9，密封盖9分别与外壳7的内侧壁及罩体4的外侧壁相顶持，密封盖9进一步确保储液部71内的液体只能通过液体通道43进入罩体4，防止储液部71内的液体漏到罩体4内。本申请实施例通过设置储液部71，使得液体可存储在外 壳7中，并通过液体通道43输出到罩体4的内部供导液片2吸收。
在一些实施例中，如图1所示，雾化器10还包括底壳8。其中，底壳8可以是一个中空部件，至少部分设置在底座1的下方，底壳8用于支撑和容纳底座1，并且底壳8与罩体4固定以封装底座1、导液片2和雾化芯3；其中，气流通道5贯穿底壳8，外部的气流可进入到气流通道5，气流通道5贯穿底壳8、底座1、导液片2、罩体4以及外壳7，因此通过气流通道5，雾化器10是内外导通的。本申请实施例通过设置底壳8，使得底壳8与罩体4固定从而对底座1、导液片2和雾化芯3做进一步的封装，防止底座1、导液片2和雾化芯3受损影响其封闭性和寿命。通过设置气流通道5，使得雾化器10的内部气压与外部一致，雾化蒸汽可以较好地传递至吸嘴中，并且外部的空气对雾化蒸汽具有导向作用。
对雾化器整体的工作原理简要说明如下：当雾化器10被使用时，电极81提供电能，发热件32与导线6电连接，导线6与电极81电连接，从而发热件32将电能转化成热能，发热件32环绕芯体31设置，使得芯体31能够充分加热从而雾化所吸收的液体，液体来自于储液部71，储液部71内的液体经液体通道43流向到导液片2，然后导液片2吸收液体并沿第二方向传导到导液片2靠近中部的区域，同时，导液片2吸收了液体的区域将吸收的液体传导到芯体31，气流通道5沿第一方向设置在抵压部42的中间区域，用户通过吸嘴72沿第一方向吸入雾化蒸汽时，外部的气流进入气流通道5，通过气流通道5内的气流运动可以加速液体雾化蒸发以及引导雾化后的蒸汽沿气流通道5流动。
以上所述，仅为本申请的较佳实施例而已，并非用于限定本申请的保护范围。
