  • the oil absorbing rope draws the smoky oil into the heating wire, and the heating wire temperature rises after heating.
  • the smoke on the oil absorbing rope is volatilized by heat, forming smoke, and is sucked into the mouth of the smoker from the mouthpiece. Since there is no burning, the content of harmful substances such as carbon monoxide and tar is relatively small, which greatly reduces the harm of second-hand smoke.
  • Low-temperature heating smoke is also known as heating non-burning smoke. It is more common in the form of cigarettes. However, unlike traditional cigarettes that produce flue gas, the low-temperature heating smoke designed with the idea of “heating without burning” can make the tobacco just enough heating. The degree of taste is emitted without igniting the tobacco leaves. Normally, ordinary cigarettes produce a lot of harmful substances under the high temperature of 400 ° C to 1000 ° C, while low temperature heating smoke mostly works below 400 ° C, which greatly reduces harmful substances in first-hand smoke and second-hand smoke. However, the conventional electric heating elements of the low-temperature heating smoke and the electronic cigarette are disposed in the smoking article, and the tar generated during the long-term use is likely to contaminate the smoking article and the harmful harmful substances are removed.

本申请要求2018年04月28日申请的，申请号为201810404619.7，名称为“气溶胶生成装置和系统”的中国专利申请的优先权，在此将其全文引入作为参考。
技术领域
本申请涉及气溶胶生成装置和气溶胶生成系统。
背景技术
传统的电子烟主要由雾化器、电池部、烟嘴组成。电池部提供电源，对雾化器的电热丝进行加热。电热丝一般都会缠绕有吸油绳，吸油绳的两端放入烟油容腔内，当烟油容腔充入烟油后，吸油绳将烟油吸入发热丝处，加热后的发热丝温度升高，吸油绳上的烟受热挥发，形成烟雾，从烟嘴部吸入吸烟者口中。由于没有经过燃烧，故而一氧化碳和焦油等有害物质含量较少，较大程度减少了二手烟危害。
低温加热烟又称加热不燃烧烟，以卷烟形式比较多见，但与传统的燃烧产生烟气的卷烟不同，以“加热不燃烧”为思路设计的低温加热烟，能使烟叶刚好加热到足以散发出味道的程度而不点燃烟叶。通常情况下，普通卷烟在400℃至1000℃的吸食高温下会产生众多有害物质，而低温加热烟大多是在400℃以下工作，使一手烟和二手烟中的有害物质大幅减少。但是传统的低温加热烟和电子烟的通电加热元件设置在烟具中，长时间使用过程中产生的焦油容易污染烟具，且不利有害物质清除。

可以理解，当所述通电加热元件120本身不需要与装置电极之间产生磁性作用力，而是通过制品电极与装置电极连接时，通电加热元件120的材料的选择范围较宽。具体的，所述类二维结构的通电加热元件120可以为由导电材料，如金属、合金或碳材料制造的箔层或薄膜，例如金属箔、合金箔、碳纸、碳纤维纸、碳纤维膜、碳纳米管薄膜等。所述金属箔和合金箔的材料可以选自但不限于金、银、铜、铝、镍、铬、铁、不锈钢、镍铬合金、铁铬铝合金、钯合金等中的一种或多种。另外，所述类二维结构的通电加热元件120的材料也可以是所述金属、合金或碳材料与其他无机或有机材料复合得到的复合材料，例如与陶瓷颗粒、玻璃纤维、高分子聚合物等复合得到的复合材料。
在一实施例中，所述通电加热元件120包括与所述烟料110均匀混合的通电加热材料，所述通电加热材料为粉末状、小片状、小颗粒状或短纤维状，所述通电加热材料与所述烟料110混合并且相互连接形成导电通路，使电流更为均匀的导入气溶胶生成制品100内部，对局部区域的烟料110进行均匀加热。所述通电加热材料的尺寸例如可以为10纳米至5毫米。所述通电加热材料例如可以是金属或合金的粉末或碎屑，或者导电碳材料，如碳纳米管、石墨烯、碳纤维、无定型碳或石墨的颗粒或粉体。
理论上只要将通电加热元件120的两端连接至气溶胶生成装置200的装置电极即可对通电加热元件120供电，达到通电加热烟料110的目的。例如，当所述通电加热元件120 为筒状结构，包裹于烟料110之外时，所述通电加热元件120与所述装置电极相对的部分可以直接与装置电极接触从而电连接。为更好的与装置电极电连接，气溶胶生成制品100可包括所述制品电极，如第一制品电极122和第二制品电极124。所述制品电极的材料可以为相对于通电加热元件120导电性更好的材料，形态可以为层状、膜状、丝状、片状或块状等。所述制品电极可以分别与所述通电加热元件120焊接、通过卡扣固定连接或通过导电胶粘结。或者，制品电极也可以通过镀膜、喷涂或印刷的方式形成在所述通电加热元件120的表面。
为使气溶胶生成装置200的装置电极和气溶胶生成制品100的制品电极容易的相互接触从而实现电连接，所述装置电极在所述容纳腔204中的位置与制品电极在所述气溶胶生成制品100上的位置相对应，使气溶胶生成制品100设置在所述气溶胶生成装置200时所述装置电极与制品电极相面对。在一实施例中，所述气溶胶生成制品100的尺寸，例如径向尺寸，与所述容纳腔204的尺寸，例如径向尺寸相配合，使所述装置电极和制品电极在使用的初期即能够相互接触。
请一并参阅图3和图4，在一实施例中，所述气溶胶生成制品100为柱状结构，所述第一制品电极122和所述第二制品电极124为沿所述柱状结构周向设置的环状结构。所述通电加热元件120为筒状结构，所述第一制品电极122和第二制品电极124分别设置在筒状结构沿轴向的两端，绕气溶胶生成制品100周向延伸，使通电加热元件120的各个位置均匀的通入电流从而使温度均匀。相对应的，所述气溶胶生成装置200的壳体包括能够限定所述容纳腔204的筒状侧壁202，所述装置电极包括环状结构的第一装置电极222和第二装置电极224，沿周向设置在所述筒状侧壁202的内表面，且所述第一装置电极222和第二装置电极224的在容纳腔204轴向上的位置与所述第一制品电极122和第二制品电极124的位置对应，从而使气溶胶生成制品100设置在所述气溶胶生成装置200时所述第一装置电极222正好与所述第一制品电极122相对，所述第二装置电极224正好与所述第二制品电极124相对。环状的第一制品电极122和第二制品电极124的外径等于或稍小于环状的第一装置电极222和第二装置电极224的内径。
环状的第一装置电极222和第二装置电极224可以对所述气溶胶生成制品100产生沿径向向外的拉力，防止气溶胶生成制品100变形引起的装置电极和制品电极之间的接触不良。尤其是当通电加热元件120和制品电极为易变形的柔性材料，例如作为包裹烟料110的烟纸使用时，随着烟料110的不断加热和挥发，气溶胶生成制品100在径向上容易产生较大的形变，例如整体或局部的塌陷和收缩，装置电极有利于维持受其吸附的制品电极和/或通电加热元件120的形状，实现持续稳定的电连接。
请参阅图5，在另一实施例中，每个装置电极包括多个沿周向排列在所述筒状侧壁202的内表面的装置子电极222’。多个装置子电极222’之间可以相互间隔设置，例如等间隔设置。相对于与筒状侧壁202尺寸配合的一体结构的环状装置电极，多个装置子电极222’共同形成环状的方式对尺寸精度要求相对较低，制造相对容易。在一实施例中，同一装置电极中的装置子电极222’共同连接至同一电压源，具有相同电位。
可选择的，所述制品电极也可包括多个制品子电极122’，所述多个制品子电极122’沿所述气溶胶生成制品100的周向排列，且位置与所述装置子电极222’一一对应。
请参阅图6和图7，气溶胶生成装置200可进一步包括设置在侧壁202和装置子电极222’之间的弹簧250，装置子电极222’通过弹簧250固定在侧壁202的内表面。所述装置子电极222’共同形成的环形结构的内径略小于制品电极的外径，在将气溶胶生成制品100装入容纳腔204的初期，所述弹簧250即被压缩，从而使在施加磁力的同时提供弹性力，使装置子电极222’与制品电极更牢固的连接，同时还可以降低气溶胶生成制品100与容纳腔204的尺寸配合精度要求。
请参阅图8，在另一实施例中，所述壳体的筒状侧壁202由两个可拆分的弧形侧壁202拼合而成，所述装置电极也由两个分别设置在弧形侧壁202上的弧形装置子电极222’组成。在使用时可以将弧形侧壁202打开后从侧方装入气溶胶生成制品100，再扣合两个弧形侧壁202，从而更容易的将气溶胶生成制品100放入容纳腔204的同时压缩弹簧250。
请参阅图9，在另一实施例中，气溶胶生成制品100还包括绝热层140，能够将烟料110分隔成不同区域。所述气溶胶生成制品100的制品电极包括多对由第一制品电极122和第二制品电极124组成的制品电极对，通电加热元件120也包括多个子加热元件120’，每个子加热元件120’分别与一制品电极对连接，能够对不同区域的烟料110进行加热。每个区域均包括各自的子加热元件120’和制品电极对。相对应的，所述装置电极包括设置在不同位置的多对由第一装置电极222和第二装置电极224组成的装置电极对，能够独立控制，多个制品电极对的位置与多个装置电极对的位置一一对应，对不同区域的烟料110分别加热。在一实施例中，所述绝热层140沿径向延伸，将烟料110在气溶胶生成制品100的轴向上分隔成多个区域。在另一实施例中，绝热层140沿轴向延伸，将烟料110在气溶胶生成制品100的径向上分隔成多个区域。
请参阅图10至图12，在一实施例中，第一制品电极122和第二制品电极124沿气溶胶生成制品100长度方向延伸，例如第一制品电极122和第二制品电极124的长度方向平行于气溶胶生成制品100的轴向，使筒状结构的通电加热元件120沿周向导通。第一制品电极122和第二制品电极124与气溶胶生成装置200的装置电极，例如第一装置电极222 和第二装置电极224的位置一一对应。在一实施例中，第一制品电极122和第二制品电极124相互间隔的设置在筒状结构的通电加热元件120径向上的两端，第一装置电极222和第二装置电极224相互间隔的设置在筒状侧壁202径向上的两端。第一装置电极222和第二装置电极224的形状可以与第一制品电极122和第二制品电极124的形状分别对应，例如第一装置电极222和第二装置电极224的长度方向平行于筒状侧壁202的轴向，且长度与制品电极的长度基本相同。
可以理解，由于装置电极与制品电极之间能够产生磁力吸引，可以帮助装置电极与制品电极之间定位。使用者在将气溶胶生成制品100设置在气溶胶生成装置200的容纳腔204中时，可以容易的通过磁力使气溶胶生成制品100转动，使制品电极的位置对应于装置电极。
上述各实施例中的第一制品电极122和/或第二制品电极124可以为复合电极，包括能够导电的第一元件与能够产生磁力吸附的第二元件。所述第二元件可环绕所述第一元件设置，或者与所述第一元件层叠设置。所述第一元件的材料可以选择为相对于第二元件具有更好导电性的材料，所述第二元件的材料可以选择为相对于第一元件具有更好导磁性、更高居里温度和更高剩磁的材料。
上述各实施例中的第一装置电极222和/或第二装置电极224也可以为复合电极，包括能够导电的第三元件与能够产生磁力吸附的第四元件。所述第四元件可环绕所述第三元件设置，或者与所述第三元件层叠设置。所述第三元件的材料可以选择为相对于第四元件具有更好导电性的材料，所述第四元件的材料可以选择为相对于第三元件具有更好导磁性、更高居里温度和更高剩磁的材料。
在一实施例中，也可以通过所述装置电极、通电加热元件和/或制品电极，或者通过单独设置的元件，使所述气溶胶生成装置200与气溶胶生成制品100之间在需要时或需要的位置上产生磁性斥力从而相远离。例如在需要使气溶胶生成制品100从容纳腔204中取出时，或者检测到温度过高、检测到短路等不正常通电状态，需要使电连接断开时。所述磁性斥力可以是通过控制电磁铁产生的磁场方向改变实现。
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申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范 围。因此，本申请专利的保护范围应以所附权利要求为准。
