本申请要求于2019年11月26日提交中国专利局、申请号为2019111710844、发明名称为“气溶胶生成制品、电子雾化装置及吸波相变体制备方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域

技术背景

具体实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施方式。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施方式。相反地，提供这些实施方式的目的是使对本发明的公开内容理解的更加透彻全面。
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。本文所使用的术语“内”、“外”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
参阅图1，一实施例提供的雾化介质11，包括基质体100、温控体200和吸波体300，通过将该三者均匀混合即可形成上述雾化介质11。在混合均匀后，可以通过压实设备将者进行压实处理，使得雾化介质11处于压实而非蓬松的状态，确保雾化介质11具有一定的形状。本实施例中，压实后的雾化介质11可以呈圆柱体状，即类似于普通香烟的形状。
在一些实施例中，基质体100可以为烟草。基质体100可以呈颗粒状，也可以呈具有一定长度的丝条状。基质体100可以通过加热不燃烧的方式雾化形成烟雾，其雾化温度可以低于350℃。
温控体200可以呈颗粒状。温控体200可以为硝酸钾、硝酸钙和硝酸钠三种材料的混合物。当温控体200达到预设温度阈值时，温控体200可以产生相变而吸收热量，在吸收热量并产生相变的过程中，温控体200自身的温度可以保持不变，或者升温缓慢且升幅较小，例如升温不高于1℃。预设温度阈值的取值可以为约300℃至约350℃，其具体取值可以为300℃、310℃、340℃或350℃等。在一些实施例中，温控体200的相变可以为固-固相变。例如，温控体200具有第一固相和第二固相。第一固相为结晶固态，第二固相为无定型固态。温控体200吸收热量后可以从第一固相转化为第二固相，反之，释放热量后，温控体200可以从第二固相再转化为第一固相。在一些实施例中，温控体200的相变可以为固-液相变。例如，温控体200具有固相和液相，温控体200吸收热量后可以从固相转化为液相，反之，释放热量后，温控体200可以从液相再转化为固相。
吸波体300也可以呈颗粒状。吸波体300可以采用氧化锌材料制成。吸波体300能够吸收微波。吸收微波后的吸波体300能迅速升温并产生热量，吸波体300能够将热量传导至基质体100和温控体200。
传统的气溶胶生成制品通常采用发热片插入气溶胶生成制品的方式对其进行加热。上述电加热方式使得发热片相对吸波体300升温速度较慢，再加上热量从发热片传导至气溶胶生成制品还需要一段时间，导致气溶胶生成制品从常温升高至雾化温度往往需要10秒至30秒的时间，这难以快速雾化基质体形成烟雾。并且，距离发热片相对较远的部分气溶胶生成制品吸收热量的机会较少，使得该 部分气溶胶生成制品更加难以快速雾化形成烟雾，进一步导致气溶胶生成制品中各处的雾化速度存在快慢差异。
而根据本实施例，当吸波体300吸收微波之后，由于微波加热机制的特殊性，吸波体300的中心部和边缘部同时产生热量而升温，故吸波体300能在极短时间内迅速升温，这样使得吸波体300能在短时间内向基质体100传导大量的热量而使基质体100快速升温，从而缩短基质体100从常温升高到雾化温度所需的时间，最终使得基质体100能够在短时间(低于0.5秒)内快速雾化以形成可供抽吸的烟雾，确保整个雾化介质11具有良好的用户体验。同时，由于吸波体300均匀分布在雾化介质11中，每个吸波体300可以看成为一个热源，使得雾化介质11中的基质体100从各热源处吸收热量的机会均等，确保雾化介质11中各处的基质体100均能在相同的短时间内升高至雾化温度以雾化，即整个雾化介质11中各处的雾化速度相同。
另外，由于引入了温控体200，可以使得基质体100的最高温度能够被有效控制，确保基质体100的最高温度不超过温控体200的预设温度阈值。具体地，当基质体100的最高温度达到温控体200的预设温度阈值时，温控体200产生相变而持续吸收热量，温控体200本身不升温或升幅较小，在吸波体300所产生的一部分热量被温控体200吸收的情况下，基质体100无法吸收多余的热量而继续升温，从而避免基质体100因超过最高温度而产生烧焦，防止产生烧焦过程中所形成的烟垢和其它有害气体。
同时参阅图2至图4，在一些实施例中，在将基质体100、温控体200和吸波体300混合形成雾化介质11的过程中，首先将温控体200和吸波体300两者混合形成一体形式的吸波相变体500，该吸波相变体500记为第一吸波相变体510，然后再将第一吸波相变体510与基质体100两者混合形成雾化介质11。第一吸波相变体510同样可以呈颗粒状。
参阅图3，在一个实施例中，一个温控体200嵌入在吸波体300的内部。吸波体300的内部仅开设一个容积较大的容置孔310。容置孔310可以呈球形，并使得温控体200填满容置孔310。吸波体300包裹容置孔310中的温控体200而形成第一吸波相变体510。换言之，在单个的第一吸波相变体510中，吸波体300包裹一个体积较大的温控体200。在该第一吸波相变体510中，吸波体300的体积略大于温控体200的体积。
参阅图4，在另一个实施例中，多个离散的温控体200嵌入在吸波体300的内部。吸波体300的内部开设有多个容积较小的容置孔310。容置孔310同样可以呈球形并均匀分布在吸波体300的内部，各个容置孔310相互独立而互不连通。通过将每个容置孔310中都填满有温控体200，吸波体300包裹容置孔310中的全部温控体200而形成第一吸波相变体510。换言之，在单个的第一吸波相变体510中，多个温控体200呈离散状分布在吸波体300的内部，即吸波体300包裹 多个离散且体积较小的温控体200。在该第一吸波相变体510中，吸波体300的体积远大于单个温控体200的体积。
在上述第一吸波相变体510中，吸波体300产生的热量直接传导至温控体200和基质体100，温控体200的相变可以为固-液相变，由于吸波体300的包裹作用，液态的温控体200将收容在容置孔310中而无法溢出至吸波体300之外以构成泄露损失。当然，温控体200的相变也可以为固-固相变。
参阅图5，在一些实施例中，雾化介质11还包括导热体400。导热体400可以采用导热性能良好的材料制成。在将基质体100、温控体200和吸波体300混合形成雾化介质11的过程中，首先将导热体400、温控体200和吸波体300混合形成一体形式的吸波相变体500，该吸波相变体500记为第二吸波相变体520，然后再将第二吸波相变体520与基质体100两者混合形成雾化介质11。第二吸波相变体520同样可以呈颗粒状。
具体地，导热体400内开设有多个容置孔310，各容置孔310可以为大小相等且呈球形。多个容置孔310同样相互独立且互不连通。一部分容置孔310中填满温控体200，另一部分容置孔310中则填满吸波体300。导热体400包裹温控体200和吸波体300而形成第二吸波相变体520。换言之，在单个的第二吸波相变体520中，多个温控体200和多个吸波体300均呈离散状分布在导热体400的内部，即一个导热体400包裹多个离散且体积较小的温控体200和吸波体300。在该第二吸波相变体520中，温控体200和吸波体300两者的体积可以大致相等，而导热体400的体积则远大于温控体200和吸波体300的体积。
在上述第二吸波相变体520中，吸波体300产生的热量将通过导热体400间接传导至温控体200和基质体100，同样地，由于容置孔310的收容作用，液态的温控体200将收容在容置孔310中而无法溢出至导热体400之外，温控体200的相变也可以为固-固相变。
参阅图1，在其它实施例中，在混合的过程中，温控体200与吸波体300可以彼此分离而处理相互独立状态，即不再将温控体200和吸波体300合成一个中间形态的吸波相变体500，而是将温控体200、吸波体300、基质体100三者直接混合形成雾化介质11。此时，吸波体300不会对温控体200产生包裹作用，且吸波体300和温控体200两者也不会同时被其它物质包裹。在该实施例中，为防止相变后液态温控体200的自由流动和泄露，温控体200的相变采用固-固相变。
同时参阅图6和图7，在一些实施例中，提供了一种气溶胶生成制品10，其包括雾化介质11和保护层12。保护层12可以采用纸质材料制成。保持层12附着在雾化介质11的侧周面上，即雾化介质11被包覆在保护层12内。当然，在其他实施例中，保护层12也可以完全覆盖整个雾化介质11的表面。保护层12的作用是可以对雾化介质11形成一定的约束力，防止雾化介质11在外力作用下产生材料脱离而形成局部坍塌。
同时参阅图8和图9，在一些实施例中，气溶胶生成制品10还包括过滤段610、冷却段630和第一滤波膜620。雾化介质11和过滤段610分居两端，冷却段630位于中间，即冷却段630的上端与过滤段610连接，冷却段630的下端与雾化介质11连接。第一滤波膜620附着在过滤段610靠近雾化组件700的一端，即第一滤波膜620位于过滤段610的下端。第一滤波膜620可以防止微波穿透，以减少微波损失。过滤段610可以采用棉质材料制成，其功能与普通香烟中过滤嘴的功能类似，可以过滤烟雾中的有害悬浮微粒以防止其被用户吸收。同时，当烟雾经过冷却段630时，烟雾将与冷却段630产生热量交换，使得烟雾的温度合理降低，防止温度偏高的烟雾对用户形成烫热的不适感。
参阅图15，还提供一种制备吸波相变体的方法。通过该方法可以制备形成上述第一吸波相变体510。该方法主要包括以下步骤：
步骤S901，将硝酸钾、硝酸钙和硝酸钠均匀混合后形成混合原料，并将所述混合原料加热熔化形成熔融液。
具体地，混合原料按重量份计包括约10至约30份的硝酸钾、约10至约40份的硝酸钙和约30至约80份的硝酸钠。可以将硝酸钾、硝酸钙和硝酸钠构成的混合原料置于坩埚中，并将坩埚放入电炉等加热设备中，将电炉的温度加热至约330℃至约380℃，使得上述混合原料熔化形成液体的熔融液，再通过搅拌使熔融液混合均匀。
步骤S902，将所述熔融液保温一段时间后冷却至室温，得到混合相变粉末。
具体地，将熔融液在其最高温度点处保温约3h至约8h，然后将熔融液在电炉中随炉冷却至室温，此时，熔融液将转化形成混合相变粉末。
步骤S903，制备二水合乙酸锌的乙醇溶液，和草酸乙醇溶液。
具体地，将二水合乙酸锌溶解于无水乙醇中以形成二水合乙酸锌的乙醇溶液。将草酸溶解于另外的无水乙醇中以形成草酸乙醇溶液。
更具体的，可以准备第一容器和第二容器，在第一容器和第二容器中分别加入无水乙醇。在第一容器的无水乙醇中加入二水合乙酸锌，并对第一容器加热使得二水合乙酸锌完全溶解于无水乙醇中，加热的温度可以为约40℃至约60℃。当二水合乙酸锌完全溶解后，即将形成二水合乙酸锌的乙醇溶液。在第二容器的无水乙醇中加入草酸，充分搅拌溶解后形成草酸乙醇溶液。
步骤S904，将所述混合相变粉末和所述草酸乙醇溶液加入至所述二水合乙酸锌的乙醇溶液中，加热搅拌以形成凝胶。
具体地，首先可以采用诸如超声波振动的方式将混合相变粉末分散，超声波振动的时间为约10min约20min。然后将分散后的混合相变粉末加入至第一容器的二水合乙酸锌的乙醇溶液中。接着，再将第二容器中的草酸乙醇溶液缓慢加入至第一容器中。最后在加热的条件下对第一容器中的混合溶液进行高速搅拌，加热的温度可以为约70℃至约90℃，此时，第一容器中的混合溶液将转化为凝胶。
步骤S905，凝胶经陈化和干燥处理后再煅烧得到所述吸波相变体。
具体地，将凝胶放入高温炉中煅烧，煅烧的温度为约400℃至约800℃，煅烧的时间为约2h至约8h。经过上述煅烧处理后，凝胶将转化为第一吸波相变体510，即吸波体300仅包裹一个温控体200。
参阅图10，还提供一种电子雾化装置20。该电子雾化装置20用于将上述雾化介质11通过加热不燃烧的方式雾化形成烟雾。该电子雾化装置20包括雾化组件700和微波发生器800。雾化组件700包括加热部710，加热部710开设有加热腔711和传输通道712，加热腔711与外界和该传输通道712均连通，加热腔711用于收容雾化介质11。微波发生器800与雾化组件700连接，微波发生器800产生的微波通过传输通道712进入加热腔711。由于雾化介质11位于加热腔711内，雾化介质11中的吸波体300将吸收微波并产生热量，吸波体300的热量再传导至基质体100、以使基质体100达到雾化所需的温度。同时，温控体200可以产生相变以吸收多余的热量，从而防止基质体100温度过高而产生烧焦。
在一些实施例中，加热部710采用金属材料制成，使得加热部710对微波具有很好的反射功能，防止进入加热腔711内的微波穿透加热部710而造成微波损失。当微波在加热腔711内多次反射时，吸波体300将对加热腔711内的微波进行全部吸收，提高能量的利用率。在另一些实施例中，加热部710也可以采用陶瓷材料或聚四氟乙烯材料等非金属材料制成，此时，雾化组件700还包括金属反射层(图未示)。金属反射层同时覆盖在加热腔711的底壁711b和侧壁711a上。通过设置金属反射层，同样可以防止微波穿透加热部710损失，保证吸波体300将加微波进行全部吸收。
同时参阅图10至图13，在一些实施例中，微波发生器800包括环绕加热腔711设置的阴极810和阳极820，阴极810相对阳极820更加靠近加热腔711。加热腔711的侧壁711a环绕加热腔711的底壁711b设置，传输通道712设置在加热腔711的底壁711b上。阳极820和阴极810激发产生的微波通过底壁711b上的传输通道712进入加热腔711内。传输通道712的数量可以为一个或多个。通过该设置可以使得整个电子雾化装置20的结构更加紧凑。
参阅图12，在一些实施例中，雾化组件700还包括过滤体720和第二滤波膜730。过滤体720可以采用陶瓷材料制成，过滤体720用于插置在加热腔711中以密封加热腔711。过滤体720也与普通香烟中过滤嘴的功能类似，可以过滤烟雾中的有害悬浮微粒以防止其被用户吸收。第二滤波膜730附着在过滤体720的端部。当过滤体720插置在加热腔711中时，第二滤波膜730位于加热腔711中。第二滤波膜730能够对微波进行反射。过滤体720具有可重复使用和插拔方便的优点。考虑到雾化介质11和过滤体720呈圆柱形，加热腔711的横截面可以设计为圆形，即加热腔711也成圆柱性，以便与加热腔711配合时，雾化介质11或过滤体720能对加热腔711形成密封作用。
当雾化介质11位于加热腔711中时，将过滤体720插置在加热腔711中。一方面，过滤体720对加热腔711起到密封作用，使得加热腔711形成一个密闭的腔体。此时，由于第二滤波膜730和加热部710对微波的反射作用，或者由于第二滤波膜730和金属反射层对微波的反射作用，进入加热腔711中的微波将无法从密闭的加热腔711中泄露，也使得吸波体300能全部吸收加热腔711内的微波，提高电子雾化装置20的能量利用率。另一方面，当用户通过过滤体720抽吸烟雾时，气溶胶生成制品10所产生烟雾经过过滤体720的过滤作用，使得烟雾中的有害悬浮微粒无法经过该过滤体720而被用户抽吸，提高电子雾化装置20使用的健康安全性。同时，过滤体720与烟雾产生热量交换，可以合理降低烟雾的温度。
参阅图13，对于自带过滤段610和冷却段630的气溶胶生成制品10，由于过滤段610具有过滤体720的过滤功能，冷却段630具有过滤体720的冷却功能。此时，可以无需使用电子雾化装置20的过滤体720，直接将整个气溶胶生成制品10插置在加热腔711中即可。由于第一滤波膜620和加热部710对微波的反射作用，或者由于第一滤波膜620和金属反射层对微波的反射作用，微波将无法从密闭的加热腔711中泄露，吸波体300能全部吸收加热腔711内的微波。并且，气溶胶生成制品10自带的过滤段610能过滤掉烟雾中的有害悬浮微粒，其自带的冷却段630能合理降低烟雾的温度。
参阅图14，雾化组件700上开设有安装腔713，传输通道712同时连通加热腔711和安装腔713，微波发生器800包括磁控管830和输出管840，磁控管830收容在安装腔713中并能产生微波，输出管840的一端与磁控管830连接，输出管840的另一端穿设在传输通道712中。磁控管830产生微波，磁控管830产生的微波通过输出管840经传输通道712进入加热腔711。传输通道712设置在加热腔711的侧壁711a上，传输通道712的数量可以为一个或多个，譬如传输通道712的数量为三个。
电子雾化装置20还包括电池910和电路板920。电池910通过电路板920与微波发生器800电性连接。当电池910对微波发生器800供电时，微波发生器800能够产生传输至加热腔711中的微波。
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发明的几种实施方式，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，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，本发明专利的保护范围应以所附权利要求为准。
