为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
在本发明的描述中，需要理解的是，术语“纵向”、“轴向”、“长度”、“宽度”、 “上”、“下”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系或者是本发明产品使用时惯常摆放的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中，“多个”的含义是至少两段，例如两段、三个等，除非另有明确具体的限定。
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，可以是两段元件内部的连通或两段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。
图1示出了本发明一些实施例中的气溶胶产生装置1以及可拆卸地插设于该气溶胶产生装置1一端的气溶胶产生基质2。该气溶胶产生装置1在一些实施例中可呈方柱状，以方便使用者手握，其可对插接于其中的气溶胶产生基质2进行低温烘烤加热，以在不燃烧的状态下释放气溶胶产生基质2中的气溶胶提取物。该气溶胶产生基质2在一些实施例中可呈圆柱状，其可包含经过处理的植物叶类固态气溶胶产生基质。可以理解地，该气溶胶产生装置1并不局限于呈方形柱状，在其他一些实施例中，其也可以呈圆柱状、椭圆柱状等其他形状。
该气溶胶产生装置1在一些实施例中可包括加热装置10以及用于承载该加热装置10的壳体20。该加热装置10在一些实施例中可呈筒状，并可供气溶胶产生基质2可拆卸地插设于其中，以从外围对气溶胶产生基质2进行加热烘烤。该气溶胶产生装置1在一些实施例中还可包括设置于壳体20内的电池（未图示）。该电池与该加热装置10电性连接，以为该加热装置10供电。
一同参阅图2至图5，加热装置10在一些实施例中可包括基体11、设置在基体11外表面上的绝缘层12、设置在绝缘层12外表面的两个发热层13以及设置在两个发热层13外表面的保护层14。可以理解地，发热层13的数量可大于两个。
基体11在一些实施例中可呈圆筒状并可采用金属材料制成，其包括在轴向的一体连接的两个加热区域以及设置在这两个加热区域之间的第一隔断113，具体地，这两个加热区域包括第一加热区域111和第二加热区域112，第一加热区域111和第二加热区域112之间设有第一隔断113。当第一加热区域111加热，第二加热区域112不加热时，第一隔断113能够减少该第一加热区域111的热量向第二加热区域112的热传递、进而减少第一加热区域111的热量散失，进而提高第一加热区域111的加热效率，降低功耗。同时，当第一加热区域111加热，第二加热区域112不加热时，可以快速提高第一加热区域111的温度，从而减少预热时间；进一步地，由于第一加热区域111的固定，被加热介质的面积减小，进而能够小面积地快速加热雾化气溶胶产生基质，提高气溶胶的浓度。
同样地，当第二加热区域112加热，第一加热区域111不加热时，第一隔断113能够减少该第二加热区域112的热量向第一加热区域111的热传递、进而减少第二加热区域112的热量散失，进而提高第二加热区域112的加热效率，降低功耗。同时，当第二加热区域112加热，第一加热区域111不加热时，可以快速提高第二加热区域112的温度，从而减少预热时间；进一步地，由于第二加热区域112的固定，被加热介质的面积减小，进而能够小面积地快速加热雾化气溶胶产生基质，提高气溶胶的浓度。
在一些实施例中，两个发热层13分别设置于两个加热区域的外侧，两个另一发热层13也可分别布置于两个加热区域的内侧。可以理解地，基体11并不局限于呈圆筒状，其也可以呈方筒状、正多边形筒状等其他筒状。再可以理解地，基体11并不局限于呈筒状，其也可以呈片状等其他形状。又可以理解地，基体11并不局限于采用金属等导电材料制成，其也可以采用导热陶瓷等非金属材料制成。可以理解地，加热区域并不局限于两个，其也可以为三个或三个以上，且每相邻的两个加热区域之间均设置一个第一隔断113。
第一隔断113在一些实施例中可包括多个切槽，每一切槽均贯基体11的内表面和外表面，使得切槽具有较佳的隔热效果。在一些实施例中，切槽可呈条形并具有一定的延伸长度。每一切槽均沿筒状基体11的周向延伸，多个切槽沿筒状基体11的周向均匀间隔分布。可以理解地，每一第一隔断113也可仅包括一个切槽。在其他一些实施例中，切槽也可不贯穿筒状基体11的内外表面，例如，切槽也可由筒状基体11的外表面向内表面延伸但不贯穿内表面。可以理解地，第一隔断113在基体11上占据的空间越多，隔热效果越好，但过多则可能会导致基体11的结构强度不够，影响加热效果。在其他实施例中，可根据基体11的材质、厚度等来设计切槽的数量和尺寸。
在一些实施例中，第一隔断113可包括多个通孔（未图示），这些通孔可沿基体11的周向间隔地分布。每一通孔均贯穿基体11的内表面和外表面。可以理解地，通孔的形状不受限制，例如其可以为圆形、椭圆形、方形或三角形等各种形状。可以理解地，多个通孔的排布方式可根据需要进行设置，例如多个通孔沿基体11的轴向分布。可以理解地，第一隔断113可通过切槽和/或通孔的方式实现，也可通过其他方式实现，在此不做局限。
绝缘层12在一些实施例中可覆盖在基体11的外表面，包括第一绝缘部121和第二绝缘部122，第一绝缘部121和第二绝缘部122分别覆盖于第一加热区域111和第二加热区域112上。第一绝缘部121和第二绝缘部122之间设有第二隔断123，第二隔断123的大小、形状以及位置与第一隔断113的大小形状以及位置相对应。绝缘层12可通过浸涂、烧结、磁控溅射、喷涂中的其中一种工艺形成，覆盖到基体11的外表面。具体地，绝缘层12在一些实施例中也可以是通过流延工艺形成的陶瓷薄膜，发热层13丝印在绝缘层12后将陶瓷薄膜卷绕于基体11上且使发热层13位于相背于基体11的一侧，然后将陶瓷薄膜和发热层13烧结于基体11上。可以理解地，当基体11采用导热陶瓷等非金属材料制成时，也可以不设置绝缘层12。
发热层13在一些实施例中可为呈螺旋状的电阻膜层，其包括第一发热层以及第二发热层，第一发热层以及第二发热层分别通过丝印等方式结合于第一绝缘部121和第二绝缘部122上，从而还可实现对气溶胶产生基质的分段式加热。该第一发热层和第二发热层可沿筒状基体11的轴向分布，从而在气溶胶产生基质的轴向对其分段加热。可以理解地，第一发热层和第二发热层也可沿着基体11的周向上进行分布。当对发热层13的两极施加电压时，电流通过发热层13产生热量，实现对气溶胶产生基质的烘烤加热。可以理解地，发热层13的结构形式不受限制，例如其可以为发热膜、金属发热丝、金属发热片或金属发热网。可以理解地，发热层13并不局限于两个，其也可以为三个或三个以上。
保护层14在一些实施例中可包括第一保护部141和第二保护部142，其分别覆盖于两个发热层13上。在一些实施例中，保护层14可采用玻璃釉料或陶瓷涂料等进行施釉处理而形成。该保护层14可降低氧和杂质对发热层13的侵蚀作用，延长发热层的使用寿命。在一些实施例中，保护层14的外表面可设有第三隔断143，第三隔断143的形状、大小和位置与第一隔断113的形状、大小和位置相对应。
一同参阅图6，在一些实施例中，基体11在一些实施例中还可包括设置在基体11末端的固定区域114，该固定区域114与第二加热区域112一体连接，该固定区域114用于实现基体11的固定安装。可以理解地，在其他一些实施例中，基体11中的固定区域114与第二加热区域112也可为单独制成两个部件，与此同时，固定区域114可采用热容小、导热率低的材料制成如采用PEEK或陶瓷材料；而第二加热区域112可采用导热率高的材料制成，进而能够减少第二加热区域112上的热量的经由固定区域114传递。
可以理解的，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。
