Description

气溶胶生成设备及其加热装置 技术领域
本公开涉及电子烟技术领域，特别地，本公开涉及气溶胶生成设备及其加热装置。
背景技术
本部分提供了与本公开有关的背景信息，但是这些信息并不必然构成现有技术。
目前，随着电子产品在香烟技术的普及，提供了各种各样的用于气溶胶生成设备的加热装置，该加热装置的主要原理是通过发热元件对气溶胶生成制品进行加热，以生成供吸烟者吸入的气溶胶。目前，气溶胶生成设备的加热方式通常为管式外围加热或中心嵌入加热。管式外围加热是指加热管围绕气溶胶生成制品外侧。管式加热装置在实际工作过程中可以达到的加热温度较高，当使用者手握气溶胶生成设备进行抽吸时，气溶胶生成设备内部的高温会传递到气溶胶生成设备的外壳上，从而产生烫手的触觉。另一方面，现有的气溶胶生成设备内部的发热元件的余热通过壳体导热散发出去，导致其热能不能很好的利用，使其发热元件的发热效率降低，从而使气溶胶产生效率降低。
在相关技术中，中心嵌入加热是指加热装置插入至气溶胶生成制品内并且与气溶胶生成制品紧密接触以对气溶胶生成制品进行加热，从而使气溶胶生成制品释放多种挥发性化合物。这种加热装置由于与气溶胶生成制品直接接触，在加热过程中由气溶胶生成制品产生的烟油等渗出物不可避免地污染加热装置，影响加热装置的加热效率和使用寿命。例如，专利申请CN104010531A公开了一种插入至气溶胶生成制品内对气溶胶生成制品进行加热的加热组件，该加热组件与气溶胶生成制品直接接触。此外，一种相关技术中的加热装置设置在气溶胶生成制品的底部，通过热空气对气溶胶生成制品的底部进行集中加热，从而使得气溶胶生成制品的底部被过度加热，而气溶胶生成制品的与底部相反的另一端欠加热，从而造成加热不均匀。
发明内容
本部分提供本公开的一般概要，而不是本公开的全部范围或全部特征的全面披露。
本申请的发明人发现，现有的通过管式外围加热或中心嵌入加热方式来对气溶胶生成制品进行加热时，气溶胶生成效率不高，特别对于中心嵌入加热方式而言，这种加热装置由于与气溶胶生成制品直接接触，在加热过程中由气溶胶生成制品产生的烟油等渗出物不可避免地污染加热装置，影响加热装置的加热效率和使用寿命。
因此，存在对用于气溶胶生成设备的加热装置进行改进的需要，以克服或缓解上述技术问题的全部或者至少一部分。
本公开的示例性实施方式提供了一种用于气溶胶生成设备的加热装置，该加热装置可以构造成用于对插入到气溶胶生成设备中的气溶胶生成制品进行加热以生成气溶胶，气溶胶生成制品包括气溶胶形成基质。
加热装置可以包括：第一壁体，该第一壁体包括加热部件，加热部件构造成具有中空的筒形形状以形成中空容置部，中空容置部构造成用于对气溶胶生成制品的气溶胶形成基质进行容置，加热部件的中空容置部的内径设置成大于待插入的气溶胶生成制品的气溶胶形成基质的外径，以使得在加热部件与气溶胶形成基质之间形成第一空气通道；第二壁体，第二壁体与第一壁体沿着纵向轴线以彼此同轴的方式设置，第二壁体包括第一夹持部件，第一夹持部件构造成用于对插入到气溶胶生成设备中的气溶胶生成制品进行夹持并且具有通气槽道，第二壁体设置有贯穿第二壁体的第一通气孔；以及第三壁体，第三壁体设置在第一壁体与第二壁体之间，第三壁体包括第二夹持部件，第二夹持部件设置成大致筒形的，并且第二夹持部的内径基本上等于气溶胶生成制品的外径。
根据本公开的用于气溶胶生成设备的加热装置，加热装置与气溶胶生成制品的气溶胶形成基质彼此间隔开并且形成有第一空气通道，由于加热装置不与气溶胶形成基质直接接触，从而有效避免了在加热过程中产生的烟油等渗出物对加热装置造成污染，实现了对加热装置的零清洁，提高了加热装置的加热效率并且延长了使用寿命。
在一些示例性实施方式中，加热装置还包括壳体，壳体沿着纵向轴线延伸并且在壳体内部形成有纵向延伸腔，纵向延伸腔构造成对加热装置的第一壁体、第二壁体的至少一部分、以及第三壁体进行容纳，壳体围绕加热部件设置，以在壳体与加热部件之间形成第二空气通道。
在根据本公开示例性实施方式的加热装置中，加热装置形成包括第一空气通道和第二空气通道的独特的气流流动路径，实现了对气溶胶形成基质的均匀且高效的加热。具体地，第一空气通道中的经加热的热空气能够实现对气溶胶形成基质的充分预热，第二空气通道中的经加热的热空气与第一空气通道中的经加热的热空气在气溶胶生成制品的底部处汇合，并且从气溶胶形成基质的远端部进入气溶胶形成基质，两股热气流一起对气溶胶形成基质进行高效加热，即实现了通过经加热的热空气从气溶胶形成基质的外围以及底部对气溶胶形成基质进行加热。
在一些示例性实施方式中，第一夹持部具有用于接纳气溶胶生成制品的插入口并且在与插入口相邻的内表面上设置有多个突出部，多个突出部在周向方向上彼此间隔开，并且在相邻的突出部之间形成通气槽道。
在根据本公开示例性实施方式的加热装置中，在使用者抽吸气溶胶生成制品期间，外部环境空气从第一夹持部件的插入口经由通气槽道进入加热装置，第一夹持部件的插入口可以充当进气口，提供了充分且均匀的进气。
在一些示例性实施方式中，多个突出部从第一夹持部件的内表面朝向纵向轴线延伸，并且多个突出部构造成与气溶胶生成制品的外表面相接触。
在一些示例性实施方式中，第二壁体包括与第三壁体连接的渐缩形部，在渐缩形部处设置有贯穿渐缩形部的壁部的一个或更多个第一通气孔，第一通气孔构造成沿着渐缩形部的周向方 向设置，以允许气流从第一夹持部的通气槽道经由第一通气孔进入第二空气通道。
在根据本公开示例性实施方式的加热装置中，外部环境空气从第一夹持部件的插入口进入第一夹持部件的通气槽道，进入的气流从通气槽道经由设置在渐缩形部上的第一通气孔进入第二空气通道。在加热装置的加热部件被通电而发热的情况下，进入第二空气通道的气流的温度升高，从而形成热气流。
在一些示例性实施方式中，第一壁体包括与第三壁体相邻的第一壁体近端部和与第一壁体近端部相反的第一壁体远端部，第一壁体远端部设置有开口。
在一些示例性实施方式中，第一壁体包括一个或更多个第二通气孔，一个或更多个第二通气孔设置成贯穿第一壁体的与第一壁体近端部邻近的壁部，一个或更多个第二通气孔构造成沿着周向方向设置。
在加热装置的加热部件被通电而发热的情况下，第一空气通道中的空气被加热以对气溶胶形成基质进行充分加热。第二空气通道中的经加热的热空气经由位于第一壁体远端部处的开口而与第一空气通道中的经加热的热空气在第一壁体远端部处汇合，两股热气流一起从气溶胶形成基质的远端部进入气溶胶形成基质，对气溶胶形成基质进行高效加热，从而实现了利用热空气流从气溶胶形成基质的外围以及底部对气溶胶形成基质进行均匀加热，可以最大限度地使气溶胶形成基质整体受热，提高了加热装置的蓄热效果。
此外，在使用者对气溶胶生成制品进行抽吸期间，外部环境空气经由加热装置的第二空气通道持续输入，进一步减少了传导至气溶胶生成设备的外壳的热，有效实现了对气溶胶生成设备的外壳的隔热降温，提高了用户体验感。
在一些示例性实施方式中，加热部件可以构造成包括设置在径向内部的第一材料部分和围绕第一材料部分设置的第二材料部分。
在一些示例性实施方式中，加热部件构造成包括筒形的陶瓷本体和围绕陶瓷本体设置的金属线材。可选地，金属线材以螺旋形的方式围绕陶瓷本体的外周表面延伸。

通过使加热部件设置成具有凹凸形式的花纹，使得加热装置的结构紧凑，有效增大了加热部件的单位体积的传热面积，从而提高了加热装置的传热效率。

下面结合图4至图6对气溶胶生成制品(例如烟支10)进行说明。如图6所示，烟支10包括气溶胶形成基质11、支撑部分13、冷却部分15以及滤嘴部分17。气溶胶形成基质11、支撑部分13、冷却部分15以及滤嘴部分17由包装件19包装。如图5所示，在烟支10的气溶胶形成基质11被完全插入到气溶胶生成设备的加热装置20中时，气溶胶形成基质11位于气溶胶生成设备的内部，并且冷却部分15的至少一部分可以暴露于气溶胶生成设备100(参见图15)的外部。使用者可以通过滤嘴部分17吸入气溶胶。通过加热装置20对气溶胶形成基质11进行加热时，由气溶胶形成基质11生成气溶胶，并且所生成的气溶胶可以随着被引入到烟支10中的空气穿过支撑部分13、冷却部分15、滤嘴部分17而被传输至使用者的嘴中。

加热装置20与气溶胶生成制品10的气溶胶形成基质11彼此间隔开，由于加热装置20不与气溶胶形成基质11直接接触，从而有效避免了在加热过程中产生的烟油等渗出物对加热装置20造成污染，实现了对加热装置20的零清洁，提高了加热装置20的加热效率并且延长了使用寿命。
此外，在一些示例性实施方式中，加热装置20可以包括壳体24，如图5所示，壳体24沿着纵向轴线A-A延伸并且在壳体24内部形成有纵向延伸腔，纵向延伸腔构造成对加热装置20的第一壁体201、第二壁体202的一部分、以及第三壁体203进行容纳。壳体24围绕加热部件21设置，以在壳体24与加热部件21之间形成第二空气通道52。在本申请中，壳体24可以是加热装置20的外壳，也可以是用于气溶胶生成设备的外壳。

可选地，如图2所示，第一夹持部件251的与插入口相邻的内表面上设置有多个凸肋，多个凸肋可以与烟支10紧密接触，并且第二夹持部253的内表面可以与烟支10的外表面紧密接触，以将烟支10固定到位。第一夹持部件251的插入口可以形成为喇叭形，以允许供给充足的环境空气。在一种示例中，突出部70可以构造成从第一夹持部件251的内表面朝向纵向轴线A-A沿着径向方向延伸，以在周向上将烟支10夹持到位。本公开的第一夹持部件251和第二夹持部件253不限于本文所描述的夹持部件的构型，只要夹持部件能够将烟支10固定到合适的位置即可。
在一些示例性实施方式中，第二壁体202和第三壁体203可以形成为一体件，第一壁体201可以与第二壁体202和第三壁体203以可拆卸的方式连接。第一壁体201可以与第三壁体203可以通过以下方式中的一者连接：卡扣连接、粘合连接、螺纹连接等。在另外一些示例中，第二壁体202与第三壁体203可以以可拆卸的方式连接。
应理解的是，烟支10包括近端部和远端部，气溶胶形成基质11所生成的气溶胶穿过该近端部离开烟支10并且被输送到使用者。在使用中，使用者可以对烟支10的近端部抽吸，以吸入由气溶胶形成基质11生成的气溶胶。此外，在本文的描述中，近端部指的是靠近使用者的一端部，远端部是指与近端部相反的远离使用者的端部。
在本公开的上下文中，纵向方向可以特别地表示加热装置的长度方向(例如图5所示的纵向轴线A-A的延伸方向)，周向方向可以特别地表示为与纵向方向垂直的方向，径向方向可以与加热部件的纵向方向垂直并且特别地表示加热装置的直径方向。此外，本公开的上下文中的表示数目的表述“多个”可以理解为表示两个或两个以上。
如图2所示，第二壁体202包括设置在渐缩形部253处的一个或更多个第一通气孔71，第一通气孔71设置成贯穿渐缩形部253的壁部，第一通气孔71构造成沿着渐缩形部253的周向方向设置，以允许气流从第一夹持部251的通气槽道经由第一通气孔71进入第二空气通道52。
此外，第一壁体201包括与第三壁体203相邻的第一壁体近端部和与第一壁体近端部相反的第一壁体远端部，第一壁体远端部设置有开口27。
在一些示例性实施方式中，第一壁体201包括一个或更多个第二通气孔72，一个或更多个 第二通气孔72设置成贯穿第一壁体201的与第一壁体近端部邻近的壁部，一个或更多个第二通气孔72构造成沿着周向方向设置。
第一通气孔71或第二通气孔72可以构造成具有以下形状中的任一者：圆形、矩形、菱形、三角形、椭圆形、梯形或不规则形状。第一通气孔71或第二通气孔72的形状、尺寸和布置方式不限于本公开所描述的构型，而是可以根据气溶胶生成设备的吸阻调节需要来改变。
在加热装置20的加热部件21被通电而发热的情况下，外部环境空气从第一夹持部件251的近端部经由多个突出部70之间的通气槽道、穿过第二壁体202的第一通气孔71而进入加热装置20的第二空气通道52。第二空气通道52中的空气被加热部件21加热以形成热空气流。此外，第一空气通道51中的空气被加热部件21加热而形成热空气流，该热空气流在周向上对烟支10的气溶胶形成基质11进行充分预热。另外，第二空气通道52中的部分热空气流可以经由第二通气孔72进入第一空气通道51。
第二空气通道52中的热气流可以经由第一壁体远端部处的开口27与第一空气通道51中的热气流汇合，以使得汇合的两股热气流从烟支10的远端部进入烟支10的气溶胶形成基质11以对其加热。
由此，本公开的示例性实施方式中的加热装置20形成了包括第一空气通道51和第二空气通道52的独特的气流传热路径，实现了对气溶胶形成基质11的均匀且高效的加热。具体地，第一空气通道51中的经加热的热空气能够围绕气溶胶形成基质11以对气溶胶形成基质进行充分预热，第二空气通道52中的经加热的热空气与第一空气通道51中的经加热的热空气可以在第一壁体远端部处汇合而从气溶胶形成基质11的底部进入烟支10，两股热气流一起对气溶胶形成基质11进行高效加热，即实现了通过经加热的热空气从气溶胶形成基质的外围以及底部对气溶胶形成基质进行加热。通过这种气流传热路径，加热装置20能够实现零清洁并且能够高效利用热能，节省了电力。
另外，加热部件21通电时产生的热量基本完全被烟支10的气溶胶形成基质11吸收，提升了热量利用率，进而可以节省能耗，并且减小预热时间。
此外，在使用者对烟支10进行抽吸期间，外部环境空气经由加热装置20的第二空气通道52持续输入，进一步减少了传导至气溶胶生成设备的外壳的热，在一定程度上实现了对气溶胶生成设备的外壳的隔热降温。
在一些示例中，第一夹持部件251可以由塑料材料制成。可选地，多个突出部70可以由弹性塑料材料制成。
此外，应理解的是，本申请的加热装置还可以包括另外的加热元件，另外的加热元件构造成通过其他方式对烟支10的气溶胶形成基质11进行加热，比如另外的加热元件通过插入至气溶胶形成基质中来对气溶胶形成基质进行加热。
