本申请涉及气溶胶生成制品。
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350℃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300℃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。
发明内容
基于此，为解决焦油容易累积在烟具中的问题，确有必要提供一种气溶胶生成制品。

需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。相反，当元件被称作“直接在”另一元件“上”时，不存在中间元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的。实施例附图中各种不同对象按便于列举说明的比例绘制，而非按实际组件的比例绘制。
本申请实施例所称“烟料”指发烟物质，是经加热或燃烧可以产生气味和/或尼古丁和 /或烟气的物质，即可被雾化的物质，即气溶胶生成物质。烟料可以是固态、半固态和液态。固态烟料因为透气性、组装和制作等方面的考虑，经常加工成薄片状，因此又俗称为薄片，丝状薄片也称为薄片丝。本申请实施例所讨论的烟料可为天然的或人工合成的烟液、烟油、烟胶、烟膏、烟丝、烟叶等，例如，人工合成的烟料含有甘油、丙二醇和烟碱等。所述烟液为液体，所述烟油为油状，所述烟胶为凝胶状，所述烟膏为膏状，所述烟丝包括天然的或人造的或萃取加工过的烟丝，所述烟叶包括天然的或人造的或萃取加工过的烟叶。烟料可以在被其它物质封存的形式下被加热，如保存在可遇热降解的包装中，例如微胶囊中，加热后所需挥发性物质从降解或有孔隙的封存包装中导出。
本申请实施例所述的烟料可以含有烟碱，也可以不含有烟碱。含有烟碱的烟料可以包括天然烟叶制品，以烟碱为原料制成的烟液、烟油、烟胶、烟膏、烟丝、烟叶等中的至少一种。烟液为水状，烟油为油状，烟胶为凝胶状，烟膏为膏状，烟丝包括天然的或人造的或萃取加工过的烟丝，烟叶包括天然的或人造的或萃取加工过的烟叶。不含有烟碱的烟料主要含有香味物质，例如香料，既可被雾化以起到模拟吸烟过程又起到戒烟等目的。在一实施例中，所述香料包括薄荷油。所述烟料还可包括其他添加剂，例如甘油和/或丙二醇。
请参阅图1，本申请实施例提供一种气溶胶生成制品100，包括用于产生气溶胶的烟料110，以及设置在所述烟料110附近，能够对所述烟料110加热的通电加热单元，所述通电加热单元用于连接外部电源的部分能够在磁力作用下保持与所述外部电源连接。在一实施例中，所述通电加热单元用于连接外部电源的部分具有可变形性，且能够在磁力作用下维持与所述外部电源连接的形状。
通电加热单元用于连接外部电源的部分能够在磁力作用下保持与外部电源的电连接，降低了与外部电源之间的接触电阻，使接触更为紧密和稳定，避免了接触不良带来的加热效率不高或功耗增大的问题。
请参阅图2和图3，本申请实施例还提供作为所述外部电源，为气溶胶生成制品100供电的气溶胶生成装置200。所述气溶胶生成装置200与所述气溶胶生成制品100组成气溶胶生成系统10。所述气溶胶生成装置200包括壳体，所述壳体开设有用于容纳所述气溶胶生成制品100的容纳腔204，以及设置在所述容纳腔204中的第一、第二装置电极222、224。所述气溶胶生成制品100在使用时设置在所述容纳腔204中，所述第一、第二装置电极222、224与所述通电加热单元用于连接外部电源的部分接触，使所述通电加热元件单元与所述装置电极电连接。所述第一、第二装置电极222、224中的至少一个能够与所述通电加热单元用于连接外部电源的部分之间产生磁性吸力。所述气溶胶生成装置200可进一步包括用于提供直流电的供电单元210，例如电池或用于连接外部电源的插座。所述 供电单元210的电源正负极分别与第一、第二装置电极222、224通过导线240电连接。所述气溶胶生成装置200可进一步包括控制单元230，用于控制所述供电单元210通入所述第一、第二装置电极222、224的电压和/或电流，以实现开关功能和/或加热温度调节功能。所述供电单元210和控制单元230可设置在壳体中。
所述气溶胶生成制品100中的烟料110在加热一段时间后随着物质挥发，烟料110的体积会逐渐减小，从而容易造成气溶胶生成制品100的变形，使通电加热单元用于连接外部电源的部分变形，容易导致与气溶胶生成装置200之间的电气接触不良。本申请实施例的通电加热单元能够在磁力作用下维持自身形状，从而实现通电加热单元更好的维持与气溶胶生成装置200的电连接，避免了在持续使用的过程中由于变形引起的接触不良，导致的加热效率不高或功耗增大的问题。
在一实施例中，所述第一、第二装置电极222、224中的至少一个具有磁性，例如包括永磁铁或电磁铁，对通电加热单元产生磁性吸力。所述通电加热单元用于连接外部电源的部分能够受到所述磁性吸力的吸引，例如包括具有铁磁性或亚铁磁性的材料。
在另一实施例中，所述通电加热单元用于连接外部电源的部分具有磁性，对所述第一、第二装置电极222、224中的至少一个产生磁性吸力。所述第一、第二装置电极222、224中的至少一个能够受到所述通电加热单元用于连接外部电源的部分的吸引。
由于所述通电加热单元在使用时被加热至较高温度，所述用于连接外部电源的部分能够在150℃至500℃，在一实施例中，在200℃至400℃仍然具有磁力或者能够被磁力吸引。在一实施例中，所述通电加热单元用于连接外部电源的部分的材料的居里温度大于300℃，在另一实施例中大于400℃。
在一实施例中，所述通电加热单元用于连接外部电源的部分的材料包括永磁铁和/或软磁材料。所述永磁铁可以为导电磁性材料，例如可以包括碳钢磁铁、钐钴磁铁、钕铁硼磁铁、铝镍钴磁铁、铁铬钴磁铁中的至少一种。所述软磁材料例如可以包括非晶软磁合金和纳米晶软磁合金中的至少一种，例如铁基、钴基、铁镍基和铁钴镍基等纳米晶软磁合金，或者铁基、钴基、铁镍基和铁钴镍基等非晶软磁合金。
通过将通电加热单元设置在所述气溶胶生成制品100内部，即将所述通电加热单元作为气溶胶生成制品100本身具有的元件，可以在气溶胶生成制品100的制造过程中使烟料110与通电加热单元实现更良好充分的接触，提高加热效率。通电加热单元的形状和结构可以多样化，且无需具有较高强度耐受多次插入烟料110受到的压力。所述气溶胶生成制品100可以为一次性制品，因此所述通电加热单元也可以是一次性的，避免了通电加热单元反复使用带来的问题，例如残留在通电加热单元表面的焦油等物质难以清除造成的污染 和有害物质累积。在一实施例中，所述气溶胶生成制品100为一次性香烟。
在一实施例中，所述气溶胶生成制品100还包括滤嘴130，设置在气溶胶生成制品100的气体流出端。当将所述气溶胶生成制品100设置在气溶胶生成装置200的容纳腔204中时，滤嘴130可以从所述开口暴露于外，供使用者抽吸。
为容易的与通电加热装置200电连接，所述气溶胶生成制品100设置在所述气溶胶生成装置200的容纳腔204中时，所述通电加热单元用于连接外部电源的部分暴露于外，并与气溶胶生成装置200的第一、第二装置电极222、224的位置对应，所述通电加热单元用于连接外部电源的部分与所述第一、第二装置电极222、224能够接触从而电连接。在一实施例中，所述气溶胶生成装置200的壳体具有与所述容纳腔204连通的开口，用于使气溶胶生成制品100从开口插入容纳腔204。所述壳体可包括侧壁202和底壁，相互连接形成杯状结构，用于限定出所述容纳腔204。所述第一、第二装置电极222、224暴露在所述容纳腔204中，在一实施例中为设置在所述侧壁202上。对应的，所述气溶胶生成制品100设置在所述气溶胶生成装置200的容纳腔204中时，所述通电加热单元用于连接外部电源的部分从所述气溶胶生成制品100的侧方(例如径向)暴露于外，从而使所述通电加热单元用于连接外部电源的部分能够受到沿侧向(例如径向)的向外的拉力。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，使所述通电加热单元用于连接外部电源的部分能够受到沿侧向(例如径向)的向外的拉力，有利于径向上的形状，实现持续稳定的电连接。
所述通电加热单元至少包括能够将电能转换为热能的元件，例如通电加热层120。在图1的实施例中，所述通电加热层120卷绕成筒状结构且包裹在所述烟料110外围。所述通电加热层120具有可变形性，例如为柔性结构。所述通电加热层120本身包括所述用于连接外部电源的部分，即与所述第一装置电极222和/或第二装置电极224位置对应的局部区域，至少该局部区域能够与第一装置电极222和/或第二装置电极224之间产生磁性吸引力，以维持该局部区域的形状，使两者保持较好的电连接，降低接触电阻。
具体的，所述通电加热层120的厚度可以为1纳米至1毫米，在一实施例中为500纳米至500微米，在一实施例中为1微米至10微米。所述通电加热层120本身可具有自支撑性，作为烟纸或支撑外管，在通电加热的同时起到整体性的包裹、支撑和容置所述烟料110的作用。当然，所述气溶胶生成制品100也可以包括单独的烟纸(图未示)，所述烟纸可以包裹在所述通电加热层120之外，或者夹于所述通电加热层120和所述烟料110整体之间，在前一种情形中，包裹在通电加热层120与装置电极对应区域的部分烟纸在使用时在一实施例中能够被撕下，以暴露出通电加热层120的局部区域，用于与装置电极接触而 电连接，在后一种情形中，所述烟纸可以具有较好的导热性。在一实施例中，所述通电加热层120为形成在所述烟纸内表面和/或外表面的导电层，通过所述烟纸支撑。
在本实施例中，所述通电加热层120中至少与所述第一装置电极222和/或第二装置电极224位置对应的局部区域能够产生磁力或能够被磁力吸引。
请参阅图4和图5，在一实施例中，所述通电加热单元包括所述卷绕成筒状结构且包裹在所述烟料110外围的通电加热层120；并进一步包括设置在所述通电加热层120上并与所述通电加热层120电连接的第一、第二制品电极122、124。所述第一制品电极122和/或第二制品电极124为所述用于连接外部电源的部分。所述第一、第二制品电极122、124本身具有可变形性，或者由于设置在通电加热层120上而容易变形。在气溶胶生成制品100使用过程中，所述第一装置电极222和/或第二装置电极224与对应的所述第一制品电极122和/或第二制品电极124之间产生磁性吸引力，以维持该制品电极的形状，使两者保持较好的电连接，降低接触电阻。
可以理解，在本实施例中，所述第一装置电极222和/或第二装置电极224能够产生磁力或能够被磁力吸引，而所述通电加热层120的材料选择范围可以较宽，只要能够具有导电性，并将电能转换为热能即可。具体的，所述通电加热层120可以为由导电材料，如金属、合金、导电聚合物和导电碳材料中的额至少一种制造的箔层或薄膜，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，所述通电加热层120的材料也可以是所述金属、合金、聚合物和/或导电碳材料与其他无机或有机材料复合得到的复合层，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层。

在另一实施例中，所述第一、第二制品电极122、124分别包括多个子电极，所述多个子电极沿所述筒状结构的通电加热层120的周向排列。
请参阅图6和图7，在另一实施例中，所述第一、第二制品电极122、124沿气溶胶生成制品100长度方向延伸，例如第一、第二制品电极122、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层120沿周向导通。在一实施例中，第一、第二制品电极122、124相互间隔的设置在筒状结构的通电加热层120径向上的两端。对应的，所述第一、第二装置电极222、224的长度方向平行于容纳腔204的轴向，在一实施例中为相互间隔的设置在容纳腔204的筒状侧壁202径向上的两端。所述第一、第二制品电极122、124的形状可以与所述第一、第二装置电极222、224的形状分别对应，例如均为条带状，且长度基本相同。
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，使制品电极转动到合适的位置与装置电极相互接触。

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。
