Description

烟弹 技术领域
本申请涉及电子产品领域，具体来说，是有关于一种用于电子烟的烟弹。
背景技术
随着世界各地区、政府对于烟草产品的管控与限制越来越严格，人们对烟草替代品的需求也不断地成长。电子烟装置可能是一种烟草替代品，其通过电子气雾产生装置或电子雾化装置将可雾化(vaporizable)材料(例如，烟油)雾化以产生用于使用者吸入的气雾，进而达到模拟吸烟的感官体验。相对于传统烟草产品，电子烟装置作为其替代品能够有效的降低因燃烧而产生的有害物质，进而降低吸烟的有害副作用。
在使用替换式烟弹的电子烟产品中，通常具有电触元件以将电功率传导至烟弹中，然而不良的电触元件设计将导致电功率传导效率不佳，进而使得烟弹内的烟油雾化不顺，产生不良的使用体验。
实用新型内容
本申请的目的之一在于提供一种烟弹，以解决背景技术中的问题。
依据本申请的一实施例，公开一种用于电子烟的烟弹。所述烟弹 包括具有开口的外壳以及封闭所述开口的底座。所述底座上设有进气区域和电触元件。所述电触元件具有暴露在所述底座外表面的电触面。所述进气区域的两侧分别设有所述电触面，所述电触面沿所述底座长度方向的尺寸范围为3mm～5.5mm。

具体实施方式
以下揭示内容提供了多种实施方式或例示，其能用以实现本揭示内容的不同特征。下文所述之组件与配置的具体例子系用以简化本揭示内容。当可想见，这些叙述仅为例示，其本意并非用于限制本揭示内容。举例来说，在下文的描述中，将一第一特征形成于一第二特征上或 之上，可能包括某些实施例其中所述的第一与第二特征彼此直接接触；且也可能包括某些实施例其中还有额外的组件形成于上述第一与第二特征之间，而使得第一与第二特征可能没有直接接触。此外，本揭示内容可能会在多个实施例中重复使用组件符号和/或标号。此种重复使用乃是基于简洁与清楚的目的，且其本身不代表所讨论的不同实施例和/或组态之间的关系。
再者，在此处使用空间上相对的词汇，譬如「之下」、「下方」、「低于」、「之上」、「上方」及与其相似者，可能是为了方便说明图中所绘示的一组件或特征相对于另一或多个组件或特征之间的关系。这些空间上相对的词汇其本意除了图中所绘示的方位之外，还涵盖了装置在使用或操作中所处的多种不同方位。可能将所述设备放置于其他方位(如，旋转90度或处于其他方位)，而这些空间上相对的描述词汇就应该做相应的解释。
虽然用以界定本申请较广范围的数值范围与参数皆是约略的数值，此处已尽可能精确地呈现具体实施例中的相关数值。然而，任何数值本质上不可避免地含有因个别测试方法所致的标准偏差。在此处，「约」通常系指实际数值在一特定数值或范围的正负10％、5％、1％或0.5％之内。或者是，「约」一词代表实际数值落在平均值的可接受标准误差之内，视本申请所属技术领域中具有通常知识者的考虑而定。当可理解， 除了实验例之外，或除非另有明确的说明，此处所用的所有范围、数量、数值与百分比(例如用以描述材料用量、时间长短、温度、操作条件、数量比例及其他相似者)均经过「约」的修饰。因此，除非另有相反的说明，本说明书与附随权利要求书所揭示的数值参数皆为约略的数值，且可视需求而更动。至少应将这些数值参数理解为所指出的有效位数与套用一般进位法所得到的数值。在此处，将数值范围表示成由一端点至另一端点或介于二端点之间；除非另有说明，此处所述的数值范围皆包括端点。

雾化装置100可包含烟弹(cartridge)100A及主体100B。在某些实施例中，烟弹100A及主体100B可设计为一个整体。在某些实施例中，烟弹100A及主体100B可设计成分开的两组件。在某些实施例中，烟弹100A可设计成可移除式地与主体100B结合。在某些实施例中，当烟弹100A与主体100B结合时，烟弹100A的一部分收纳于主体100B中。在某些实施例中，烟弹100A可称为储油组件，主体100B可称为本体(main body)或电池组件。在某些实施例中，烟弹100A可称为储油组件，主体100B可称为本体(main body)或电池组件。

主体100B具有主体外壳22。主体外壳22具有一开口22h。开口22h可收纳烟弹100A的一部分。开口22h可包覆烟弹100A的一部分。在某些实施例中，烟弹100A可设计成可移除式地与主体100B结合。在某些实施例中，烟弹100A可以不具有方向性。在某些实施例中，烟弹100A以两种不同方向皆可以与主体100B可移除式地结合。
图3A、3B、3C与3D演示根据本申请一些实施例的烟弹100A的示范性正面视图、侧面视图、顶面视图以及透视示意图。
烟弹100A包含烟弹外壳1以及底座9，其中烟弹外壳1的底部具有开口，底座9用于封闭烟弹外壳1的底部开口。在某些实施例中，烟弹外壳1上具有烟嘴盖(mouthpiece)1b。在某些实施例中，烟弹外壳1与烟嘴盖1b可以是分开的两个组件。在某些实施例中，烟嘴盖1b与烟弹外壳1可以由不同材料制成。在某些实施例中，烟嘴盖1b与烟弹外 壳1可以一体成形。在某些实施例中，烟嘴盖1b与烟弹外壳1可以由相同材料制成。
烟弹外壳1包括用于插入主体100B的配合部1p。配合部1p沿烟弹外壳1的长度方向。在某些实施例中，配合部1p的尺寸L在1.5mm～2.5mm的范围。在某些实施例中，配合部1p的尺寸L在1.8mm～2.2mm的范围。
如图3C所示，烟弹外壳1的顶部具有开口1h。开口1h可作为气雾出口。烟弹外壳1内包含出气通道1t。出气通道1t的一端与开口1h连通，出气通道1t的另一端与烟弹外壳1内的雾化室连通。雾化装置100产生的气雾可经由管1t与开口1h被使用者吸食。
图4演示根据本申请一些实施例的底座9的分解示意图。
底座9包含进气区域9a，进气区域9a包括凹槽9a1。凹槽9a1设有开口9h1及开口9h2。开口9h1及开口9h2可设置于进气区域9a的范围内。开口9h1及开口9h2可设置于凹槽9a1的范围内。
开口9h1及开口9h2与烟弹100A内部的雾化室连通。开口9h1及开口9h2作为进气孔，空气可经由开口9h1及开口9h2进入烟弹100A内部。
底座9另外包含设置于进气区域9a两侧的开口9h3和9h4。电触元件9p1及9p2可分别穿过开口9h3及9h4并固定于底座9上。电触 元件9p1及9p2穿过开口9h3及9h4并延伸至烟弹100A内部。电触元件9p1及9p2可具有传导电流的功能。电触元件9p1及9p2可将功率提供至烟弹100A内的气雾产生组件。在某些实施例中，烟弹100A内的气雾产生组件可以是一种加热组件。
电触元件9p1及9p2穿过开口9h3及9h4后，电触元件9p1的电触面9s1和电触元件9p2的电触面9s2暴露在底座9的外表面。
电触元件9p1及9p2可包含金属。电触元件9p1及9p2可被磁性组件吸附。烟弹100A可经由电触元件9p1及9p2被设置于主体100B内的磁性组件吸附。烟弹100A可经由电触元件9p1及9p2与主体100B可移除式地结合。
可理解地，当主体100B内的磁性组件的磁力大小相等时，若电触元件9p1的电触面9s1和电触元件9p2的电触面9s2的面积较大，通过主体100B内的磁性组件吸附时，主体100B与烟弹100A之间的吸力较为平均，因此，烟弹100A较不容易脱离主体100B。
需注意的是，本申请并不限制凹槽9a1中作为进气孔的开口数量。在某些实施例中，凹槽9a1包含有一个开口。在某些实施例中，凹槽9a1上设置有三个或多于三个开口。另外，本申请并不限制底座9上设置的电触元件的数量。在某些实施例中，底座9上设置有一个电触元件。在某些实施例中，底座9上设置有三个或多于三个电触元件。
图5演示根据本申请一些实施例的底座9的底面视图。
在某些实施例中，电触面9s1和电触面9s2沿底座9长度方向(即虚线A-A'方向)的尺寸r1在3mm～5.5mm的范围内。在某些实施例中，电触面9s1和电触面9s2沿底座9的长度方向(即虚线A-A'方向)的尺寸r1在5mm～5.1mm的范围内。在某些实施例中，凹槽9a1沿底座9的长度方向(即虚线A-A'方向)的尺寸r2不大于电触面9s1和电触面9s2沿底座9的长度方向(即虚线A-A'方向)的尺寸r1。在某些实施例中，尺寸r1与尺寸r2的差不大于0.5mm。
在某些实施例中，凹槽9a1为圆形。在某些实施例中，凹槽9a1为环形。在某些实施例中，电触面9s1和电触面9s2为圆形。在某些实施例中，凹槽9a1、电触面9s1和电触面9s2为圆形。
在某些实施例中，开口9h1及开口9h2的中心点和电触面9s1和电触面9s2位于同一直线上。在某些实施例中，开口9h1及开口9h2的中心点和电触面9s1和电触面9s2的中心点位于底座9的长度方向(即虚线A-A'方向)的沿线上。在某些实施例中，底座9的外表面呈椭圆形，换言之，底座9的长度方向即为底座9的长轴。在如此设置下，开口9h1的中心点、开口9h2的中心点、电触面9s1的中心点、和电触面9s2的中心点位于底座9的长轴上。
底座9外表面呈现的椭圆形具有中心O。在某些实施例中，开口 9h1及开口9h2分布于中心O的周围。然而，开口9h1及开口9h2的分布并非本申请的限制。在某些实施例中，凹槽9a1中至少一个作为进气孔的开口可与所述椭圆的中心O重合。
由于底座9的面积有限，因此电触面9s1和电触面9s2的面积大小的设计将影响电功率传导进入烟弹100A内。详细来说，若电触面9s1和电触面9s2的面积较小，其形成的电阻较大，电功率的损耗较大，造成电功率的传导效率不佳，进而影响烟油的雾化效果。同时，若电触面9s1和电触面9s2的面积较小，烟弹100A与主体100B之间的吸附磁力相对不均，容易造成烟弹100A的脱落。
另方面，若电触面9s1和电触面9s2的面积过大，将压缩到进气区域9a的空间，进而影响开口9h1及开口9h2的分布与面积大小，同样会影响烟油的雾化效果。
有鉴于此，申请人在经过实验后发现，当电触面9s1和电触面9s2沿底座9长度方向的尺寸r1设计在3mm～5.5mm的范围内时，电功率的传导与磁力吸附大小最为适当，同时，不会影响空气进入烟弹100A的多寡。在如此设计下，使用者能有较良好的使用体验。
