在本发明中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“上方”可以是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“下方”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
图1-3示出了本发明第一实施例中的气溶胶生成制品10，该气溶胶生成制品10呈圆柱状，其可包括外包层11、发烟基材段12以及气溶胶提取段13。气溶胶提取段13沿纵向设置于发烟基材段12的一端，外包层11包裹发烟基材段12以及至少部分气溶胶提取段13外。本实施例中的气溶胶生成制品10为由发烟基材段12和气溶胶提取段13组成的两段式结构，结构更简洁，用料更少，使得整个用料成本明显降低，且加工工艺更简便。可以理解地，在其他实施例中，气溶胶生成制品10也可呈椭圆形柱状、方形柱状等其他形状。
外包层11可呈圆筒状，其一端形成有开口110。发烟基材段12、气溶胶提取段13可经由该开口110装入到外包层11中。外包层11的材料可包括纸张、纸管、锡箔、铝箔中的一种或多种。发烟基材段12可包括丝状、片状、颗粒状、粉末状、膏状等固态发烟基材中的一种或多种。例如，外包层11采用纸管型材料，发烟基材段12可采用灌装工艺装入到外包层11中，然后再将气溶胶提取段13装入到外包层11中。灌装工艺所需的设备成本低廉，工艺简洁，操作方便，工业化简易程度高。再例如，外包层11采用纸张材料，气溶胶生成制品10可通过卷制工艺成型，具体地，可将发烟基材段12覆盖在纸张上再将纸张卷制成管状，然后将气溶胶提取段13插入到外包层11中；或者，也可将发烟基材段12和气溶胶提取段13覆盖在纸张上后再卷制成型。
外包层11包括筒状侧壁111，筒状侧壁111内沿纵向依次形成有第一腔1111和第二腔1112。第二腔1112与开口110相连通，气溶胶提取段13至少部分收容于第二腔1112。第一腔1111与第二腔1112远离开口110的一端相连通，发烟基材段12收容于第一腔1111。进一步地，外包层11还包括底壁112，底壁112设置于筒状侧壁111远离开口110的一端，可用于支撑发烟基材段12。在本实施例中，开口110、底壁112分别位于筒状侧壁111的上端和下端。
在一些实施例中，发烟基材段12、气溶胶提取段13均可分离地收容于第二腔1112内。抽吸者可将气溶胶提取段13从第二腔1112取出，然后在第一腔1111自主填充或更换发烟基材以形成发烟基材段12，填充完成后再将气溶胶提取段13装入第二腔1112，气溶胶提取段13的底部抵靠于发烟基材段12上。发烟基材段12、气溶胶提取段13可分离设置，一方面提升了气溶胶生成制品10的交互性，另一方面大大提升了发烟基材的可添加范围。
气溶胶提取段13的上端可伸出于开口110外一段距离，气溶胶提取段13伸出开口110外的部分可形成吸嘴部131，该吸嘴部131可供抽吸者抽吸使用。可以理解地，在其他实施例中，气溶胶提取段13也可完全收容于第二腔1112内。
气溶胶提取段13的外表面和第二腔1112的腔壁面之间形成有至少一个进气通道133，外界空气可由该至少一个进气通道133进入发烟基材段12。气溶胶提取段13内还贯穿形成有至少一个提取通道130，用于提取发烟基材段12产生的气溶胶并将该气溶胶输出。抽吸者抽吸时，外界空气经由至少一个进气通道133进入，随该至少一个进气通道133在发烟基材段12与气溶胶提取段13的交汇处进入至少一个提取通道130，在此处形成负压，对发烟基材段12产生的气溶胶进行卷吸，空气与气溶胶混合后形成烟气，该烟气再通过该至少一个提取通道130进入抽吸者口中。空气在发烟基材段12与气溶胶提取段13的交汇处对发烟基材段12产生的气溶胶进行卷吸时，大部分空气并未直接通过发烟基材段12进行换热，发烟基材段12未受气流扰动，所以产生的烟气温度适中，烟气较为纯净。此外，从至少一个进气通道133进入的空气也能对发烟基材段12产生的气溶胶进行降温，从而保证气溶胶提取段13的出口端的烟气温度在50℃以下。因此，本实施例可将传统的隔热段、冷却段、过滤段合并为一个气溶胶提取段13，大大简化了气溶胶生成制品10的结构。
在本实施例中，进气通道133有多个，该多个进气通道133可沿气溶胶提取段13的周向均匀间隔分布。具体地，气溶胶提取段13的外表面内凹形成有多个凹槽1330，该多个凹槽1330与第二腔1112的腔壁面之间形成多个进气通道133。每一凹槽1330均可沿气溶胶提取段13的轴向延伸，凹槽1330的横截面形状可以为圆弧形、椭圆弧形、三角形、方形等各种形状。
此外，在本实施例中，提取通道130有一个，该一个提取通道130位于气溶胶提取段13的中心位置，其可呈圆柱状并沿气溶胶提取段13的轴向延伸。可以理解地，在其他实施例中，提取通道130也可以有多个，提取通道130的横截面形状也可以为椭圆形、三角形、方形等其他形状。
进一步地，该至少一个提取通道130内还可设置有过滤材料，对烟气进行过滤，达到提升烟气纯净度的增益效果。该过滤材料可以为多孔过滤材料，其可包括醋酸纤维、聚丙烯纤维、聚乳酸纤维、树脂、植物多糖、植物多孔材料等中的一种或多种。
在一些实施例中，第一腔1111的腔壁上还可形成有至少一个进气孔1120，外界空气可经由该至少一个进气孔1120进入到第一腔1111内。该至少一个进气孔1120以及至少一个进气通道133同时进气，有助于加大烟雾量，降低吸阻及气溶胶提取段13的出口端的烟气温度。具体地，在本实施例中，该至少一个进气孔1120设置于底壁112上。在其他实施例中，该至少一个进气孔1120也可设置于第一腔1111的侧壁上。在另一些实施例中，外包层11也可不包括底壁112，从而使得第一腔1111的底端与外界连通。
在一个实施方式中，气溶胶提取段13的外径为7mm，轴向长度为45mm；气溶胶提取段13的中心设置有1个横截面为圆形的沿纵向贯穿的提取通道130，该提取通道130的孔径为5mm；提取通道130内设置有过滤材料，该过滤材料为醋酸纤维；气溶胶提取段13的外表面沿纵向设置有32个凹槽1330，每一凹槽1330的横截面为V型，深度为0.4mm；外包层11的轴向长度为35mm，壁厚为0.3mm，内径为7mm，外包层11下端的第一腔1111未封闭，即第一腔1111的腔壁上形成有进气孔1120；发烟基材段12为烟草薄片，轴向长度为12mm。
图4示出了本发明第二实施例中的气溶胶生成制品10，其与上述第一实施例的主要区别在于，本实施例中的第一腔1111的腔壁封闭不通气，发烟基材段12在无氧环境中进行加热，烟气更纯净。
在一个实施方式中，气溶胶提取段13的外径为8mm，轴向长度为45mm；气溶胶提取段13设置有7个横截面为圆形的沿纵向贯穿的提取通道130，每一提取通道130的孔径为1.5mm；气溶胶提取段13的外表面沿纵向设置有32个凹槽1330，每一凹槽1330的横截面为U型，深度为0.5mm；外包层11的轴向长度为30mm，壁厚为0.4mm，内径为8mm，外包层11的下端的第一腔1111封闭；发烟基材段12为烟草颗粒，轴向长度为12mm。
图5示出了本发明一些实施例中的气溶胶生成系统100，该气溶胶生成系统100可包括气溶胶生成制品10以及用于收容并加热气溶胶生成制品10的气溶胶产生装置20。气溶胶生成制品10可拆卸地插接于气溶胶产生装置20中，方便在加热完成后取出并更换新的气溶胶生成制品10。该气溶胶产生装置20可在通电后对插接于其中的气溶胶生成制品10进行低温烘烤加热，以在不燃烧的状态下释放气溶胶生成制品10中的气溶胶提取物。该气溶胶产生装置20大致可呈方形柱状。可以理解地，在其他实施例中，该气溶胶产生装置20并不局限于呈方形柱状，其也可以呈圆柱状、椭圆柱状等其他形状。
可以理解地，上述各技术特征可以任意组合使用而不受限制。
以上实施例仅表达了本发明的优选实施方式，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，可以对上述技术特点进行自由组合，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，凡跟本发明权利要求范围所做的等同变换与修饰，均应属于本发明权利要求的涵盖范围。
