本发明的实施例
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1是本发明气溶胶产生方法实施例一的流程图，首先说明的是，气溶胶产生装置设置成在使用中用于加热气溶胶形成基质（例如烟支）的至少两个热源，即，至少包括第一发热体及第二发热体，相应地，气溶胶形成基质包括第一部分和第二部分。而且，第一发热体用于对第一部分进行加热，第二发热体用于对第二部分进行加热。例如，在一个具体实施例中，如图2所示，气溶胶形成基质为一个完整的整体，即，其第一部分31和第二部分32并没有物理分割，当然，在其它实施例中，第一部分31和第二部分32也可为彼此独立的两个部分。第一发热体21及第二发热体22分别为圆筒状发热体，且分别套设在气溶胶形成基质的第一部分31及第二部分32上，当然，在其它实施例中，第一发热体21及第二发热体22也可为发热片、加热针、加热棒、加热线或丝，且分别插设在气溶胶形成基质的第一部分31及第二部分32上。第一发热体21及第二发热体22可以为单个发热体上的不同的区段，也可以是物理上相间隔的不同的两个发热体。
如图1所示，该实施例的气溶胶产生方法包括以下步骤： 
步骤S10.在第一阶段，对第一发热体进行加热控制，以使所述第一发热体的温度上升至第一温度，再下降至第二温度；以及，对第二发热体进行加热控制，以使所述第二发热体的温度上升至第三温度，其中，所述第三温度小于所述第二温度；
在该步骤中，在第一阶段，第一发热体及第二发热体的温度均是从初始温度开始上升的，该初始温度可为室温，例如25度、0度等。
步骤S20.在第二阶段，对所述第二发热体进行加热控制，以使所述第二发热体的温度从所述第三温度上升至第四温度；以及，对所述第一发热体进行加热控制，以使所述第一发热体的温度从所述第二温度下降至第五温度，其中，所述第四温度大于所述第五温度。
在该实施例的技术方案中，结合图3A及图3B，0～t1为第一阶段，t1～t2为第二阶段。在第一阶段（0～t1），通过对第一发热体的加热控制，先使第一发热体的温度升高到第一温度T1（第一阶段的最高温度点），这样，可以让气溶胶形成基质得到充分的预热，有利于气溶胶的产生；然后再使第一发热体的温度从第一温度T1持续下降至第二温度T2（T2<T1），这样可以让气溶胶形成基质不会过度高温烘烤，从而抑制了杂气和焦味的产生。同时，在第一阶段（0～t1），通过对第二发热体的加热控制，使第二发热体的温度上升到第三温度T3（T3<T2），这样，可以让气溶胶形成基质的第二部分提前烘烤，有利于第二部分在第二阶段产生气溶胶。在第二阶段（t1～t2），通过对第二发热体的加热控制，使第二发热体的温度上升到第四温度T4（第二阶段的最高温度点），同时，通过对第一发热体的加热控制，使第一发热体的温度下降至第五温度T5（T5<T4），从而保证抽吸时间内口感和气溶胶的质量。
进一步地，第一温度在150℃～300℃之间（包括150℃及300℃），第二温度在150℃～300℃之间（包括150℃及300℃），第二温度与第一温度的差值在5℃～100℃之间（包括5℃及100℃）。第三温度在50℃～200℃之间（包括50℃及200℃）；第四温度在150℃～300℃之间（包括150℃及300℃）。
在一个具体实施例中，如图3A、3B所示，第一温度为300℃，第二温度为240℃，第三温度为100℃，第四温度为290℃，第五温度为200℃。这样，在第一阶段，对于第一发热体，其温度先升高到300℃（第一阶段的最高温度点），从而使气溶胶形成基质的第一部分得到充分的预热，有利于该第一部分在第一阶段气溶胶的产生，然后再下降至240℃，从而使该第一部分不会过度高温烘烤，从而抑制了杂气和焦味的产生。对于第二发热体，其温度上升到100℃，从而为气溶胶形成基质的第二部分在第二阶段产生气溶胶进行预热。在第二阶段，对于第二发热体，其温度上升到290℃，从而该第二部分进行充分加热，利于气溶胶的产生；对于第一发热体，其温度下降至200℃，从而避免第一部分因过度高温烘烤而产生的杂气或焦味，保证抽吸时间内口感和气溶胶的质量。
进一步地，在一个可选实施例中，步骤S10中的对第一发热体进行加热控制，以使所述第一发热体的温度上升至第一温度，再下降至第二温度，具体包括：对第一发热体进行加热控制，以在所述第一阶段的第一时段，使所述第一发热体的温度上升至第一温度；在所述第一阶段的第二时段，使所述第一发热体的温度从所述第一温度持续下降至第二温度，或使所述第一发热体的温度先下降至所述第二温度，再维持在所述第二温度，而且，所述第一时段小于第二时段。
在一个具体实施例中，如图3B所示，0～t11为第一阶段的第一时段，t11～t1为第一阶段的第二时段。在第一阶段的第一时段，由于第一时段（例如10s）小于第二时段（例如2分钟），所以，可使第一发热体的温度快速升到第一温度T1，以对气溶胶形成基质的第一部分进行快速预热，从而避免了第一部分在开始阶段因为烘烤不足而导致的口感和气溶胶浓度不足。在第一阶段的第二时段，第一发热体的温度从第一温度T1持续下降至第二温度T2，这样可避免第一部分因温度过高而产生杂气和焦味。
在另一个具体实施例中，如图3B所示，0～t11为第一阶段的第一时段，t11～t1为第一阶段的第二时段。在第一阶段的第一时段，由于第一时段（例如10s）小于第二时段（例如2分钟），所以，可使第一发热体的温度快速升到第一温度T1，以对气溶胶形成基质的第一部分进行快速预热，从而避免了开始阶段因为烘烤不足而导致的口感和气溶胶浓度不足。在第一阶段的第二时段，第一发热体的温度在 t11～t12段内先下降至第二温度T2，在t12～t1段内维持在第二温度T2，这样，也可避免第一部分因温度过高而产生杂气和焦味。
进一步地，在一个可选实施例中，步骤S10中对第二发热体进行加热控制，以使所述第二发热体的温度上升至第三温度，包括：在所述第一阶段的第二时段，对第二发热体进行加热控制，以使所述第二发热体的温度先上升至第三温度再维持在所述第三温度，或使所述第二发热体的温度持续上升至所述第三温度。
在该实施例中，在第一发热体的温度从第一温度T1持续下降到第二温度T2的过程中，即，在第二时段，才开始对第二发热体进行加热控制，例如，如图3A所示，从第二时段的t13时刻（t13时刻在第二时段内）开始对第二发热体进行加热控制，以使其温度先上升至第三温度T3再维持在第三温度T3，这样，可避免气溶胶形成基质的第一部分因温度过高而产生杂气和焦味（因为第二发热体开始加热时，气溶胶形成基质第二部分的热量也会热传导至第一部分），也避免第二部分产生气溶胶的时间过早，气溶胶产生物质被过早地消耗，而导致在抽吸后期第二部分产生的气溶胶的浓度过低。当然，在其它实施例中，也可使第二发热体的温度持续上升至所述第三温度。
关于图3A及图3B中第二发热体在第一阶段的发热曲线，还需说明的是，虽然图3B中第二发热体的温度从第一时段开始时便开始上升，但这是因为第一发热体的热传导而导致的被动升温，第二时段的升温才是第二发热体主动加热而导致的升温。例如，在图4所示的实施例中，第一发热体21与第二发热体22为一体式管状结构，且第一发热体21与第二发热体22之间通过多个孔23进行部分间隔，当然，在其它实施例中，也可通过挖槽来进行部分间隔。这样，第一发热体21与第二发热体22之间的温度场的相互影响较小，便于单独控制第一发热体21或第二发热体22的温度，同时第一发热体21与第二发热体22之间的相对位置较为确定，便于制作和安装。
进一步地，在一个可选实施例中，对所述第二发热体进行加热控制，以使所述第二发热体的温度从所述第三温度上升至第四温度，包括：对所述第二发热体进行加热控制，以在所述第二阶段的第三时段使所述第二发热体的温度从所述第三温度上升至第四温度；在所述第二阶段的第四时段，使所述第二发热体的温度维持在所述第四温度，或使所述第二发热体的温度从所述第四温度上升至第六温度，其中，所述第三时段及所述第四时段是对所述第二阶段按第一划分方式所划分的两个时段，且所述第三时段小于所述第四段时段。
在一个具体实施例中，如图5所示，可将第二阶段（t1～t2）按第一划分方式划分成第三时段（t1～t21）及第四时段（t21～t2），且第三时段小于第四时段。对于第二阶段的第二发热体，通过对其进行加热控制，可使其在第三时段的温度从第三温度T3上升至第四温度T4，及在第四时段的温度维持在第四温度T4。由于第三时段小于第四时段，所以，第二发热体的快速预热可避免气溶胶形成基质的第二部分因为烘烤不足而导致的口感和气溶胶浓度不足。
在一个具体实施例中，如图6所示，同样将第二阶段（t1～t2）划分成第三时段（t1～t21）及第四时段（t21～t2），且第三时段小于第四时段。对于第二阶段的第二发热体，通过对其进行加热控制，可使其在第三时段的温度从第三温度T3上升至第四温度T4，及在第四时段的温度从第四温度T4上升至第六温度T6。由于第三时段小于第四时段，所以，第二发热体的快速预热可避免气溶胶形成基质的第二部分因为烘烤不足而导致的口感和气溶胶浓度不足。同时，由于第二发热体在第四时段也会升温，所以还可避免后续加热过程中因为烘烤不足而导致的口感和气溶胶浓度不足。
进一步地，在一个可选实施例中，对所述第一发热体进行加热控制，以使所述第一发热体的温度从所述第二温度下降至第五温度，包括：对所述第一发热体进行加热控制，以在第二阶段的第五时段，使所述第一发热体的温度从所述第二温度下降至第五温度；在第二阶段的第六时段，使所述第一发热体的温度维持在所述第五温度，或使所述第一发热体的温度从所述第五温度上升至第七温度，其中，所述第五时段及所述第六时段是对所述第二阶段按第二划分方式所划分的两个时段，且所述第五时段小于所述第六时段，且所述第四温度大于所述第七温度。另外，第一发热体的温度在第五时段从第二温度下降至第五温度的过程可为：按同一下降速率持续下降，还可为：先按第一下降速率缓慢下降，再按第二下降速率快速下降。
在一个具体实施例中，如图5所示，可将第二阶段（t1～t2）按第二划分方式划分成第五时段（t1～t22）及第六时段（t22～t2），且第五时段小于第六时段。对于第二阶段的第一发热体，通过对其进行加热控制，可使其在第五时段的温度从第二温度T2下降至第五温度T5，及在第六时段的温度维持在第六温度T6。这样，可避免气溶胶产生基质的第二部分不会因为过度高温烘烤而导致杂气和焦味的产生（因为第一发热体在加热时，气溶胶形成基质第一部分的热量也会热传导至第二部分）。
在一个具体实施例中，如图6所示，同样将第二阶段（t1～t2）划分成第五时段（t1～t22）及第六时段（t22～t2），且第五时段小于第六时段。对于第二阶段的第一发热体，通过对其进行加热控制，可使其在第五时段的温度从第二温度T2下降至第五温度T5，及在第六时段的温度从第五温度T5上升至第六温度T6，这样既可避免气溶胶产生基质的第二部分不会因为过度高温烘烤而导致杂气和焦味的产生，又由于第一发热体在第六时段也会升温，所以又可避免气溶胶产生基质的第二部分因为烘烤不足而导致的口感和气溶胶浓度不足。
进一步地，在一个可选实施例中，可采用电磁加热方式对第一发热体进行加热控制；和/或，采用电磁加热方式对第二发热体进行加热控制。而且，对两个发热体的控制可采用独立控制方式，也可集中控制方式。 
在一个具体实施例中，采用电磁加热方式对第一发热体进行加热控制，具体包括：
实时检测所述第一发热体的温度，以获取第一温度检测值；
根据所述第一发热体的所述第一温度检测值及在每个阶段的目标温度输出第一控制信号，其中，所述第一发热体在第一阶段的目标温度为所述第一温度、所述第二温度，第二阶段的目标温度为所述第五温度；

相应地，采用电磁加热方式对第二发热体进行加热控制，具体包括：

根据所述第二控制信号产生相应的第二交变磁场，且所述第二发热体位于所述第二交变磁场内。
在上述实施例中，可在第一发热体及第二发热体的表面上分别设置热敏电阻，并通过检测每个热敏电阻的电压值来计算出热敏电阻的阻值，从而得到第一发热体及第二发热体的实时温度检测信号。另外，还设置两个分别用于产生第一交变磁场及第二交变磁场的谐振电路，该谐振电路的线圈可产生交变的电磁场，且两个发热体分别置于相应的电磁场，从而会在表面产生感应涡电流使发热体发热。而且，由主控模块通过软件算法根据所检测的两个部分的温度检测信号来控制谐振电路的震荡的强度。
当然，第一发热体及第二发热体对气溶胶形成基质加热的方式还可以是红外辐射加热、电阻加热等，在此不作限制。
图7是本发明气溶胶产生装置实施例一的逻辑结构图，该实施例的气溶胶产生装置100包括：第一发热体21、第二发热体22、第一控制单元11、第二控制单元12。另外，气溶胶形成基质包括第一部分和第二部分。而且，第一发热体21用于对第一部分进行加热，第二发热体22用于对第二部分进行加热。例如，在一个具体实施例中，如图2所示，气溶胶形成基质是一个完整的整体，即，其第一部分31和第二部分32并没有物理分割，当然，在其它实施例中，第一部分31和第二部分32也可为彼此独立的两个部分。第一发热体21及第二发热体22分别为圆筒状发热体，且分别套设在气溶胶形成基质的第一部分31及第二部分32上，当然，在其它实施例中，第一发热体21及第二发热体22也可为发热片、加热针、加热棒、加热线或丝，且分别插设在气溶胶形成基质的第一部分31及第二部分32上。
在图7所示的实施例中，第一控制单元11用于在第一阶段，对第一发热体21进行加热控制，以使所述第一发热体21的温度上升至第一温度，再下降至第二温度；以及，在第二阶段，对第一发热体21进行加热控制，以使所述第一发热体21的温度从第二温度下降至第五温度；第二控制单元12用于在第一阶段，对第二发热体22进行加热控制，以使所述第二发热体22的温度上升至第三温度；以及，在第二阶段，对第二发热体22进行加热控制，以使所述第二发热体22的温度从第三温度上升至第四温度，其中，第三温度小于第二温度，第四温度大于第五温度。
进一步地，第一控制单元11用于对所述第一发热体进行加热控制，以在所述第一阶段的第一时段，使所述第一发热体的温度上升至第一温度；在所述第一阶段的第二时段，使所述第一发热体的温度从所述第一温度持续下降至所述第二温度，或使所述第一发热体的温度先下降至所述第二温度，再维持在所述第二温度，而且，所述第一时段小于第二时段。
进一步地，第二控制单元12用于在所述第一阶段的第二时段，对第二发热体进行加热控制，以使所述第二发热体的温度先上升至第三温度再维持在所述第三温度，或使所述第二发热体的温度持续上升至所述第三温度。
进一步地，第二控制单元12用于对所述第二发热体进行加热控制，以在所述第二阶段的第三时段使所述第二发热体的温度从所述第三温度上升至第四温度；在所述第二阶段的第四时段，使所述第二发热体的温度维持在所述第四温度，或使所述第二发热体的温度从所述第四温度上升至第六温度，其中，所述第三时段及所述第四时段是对所述第二阶段按第一划分方式所划分的两个时段，且所述第三时段小于所述第四段时段。
进一步地，第一控制单元11用于对所述第一发热体进行加热控制，以在第二阶段的第五时段，使所述第一发热体的温度从所述第二温度下降至第五温度；在第二阶段的第六时段，使所述第一发热体的温度维持在所述第五温度，或使所述第一发热体的温度从所述第五温度上升至第七温度，其中，所述第五时段及所述第六时段是对所述第二阶段按第二划分方式所划分的两个时段，且所述第五时段小于所述第六时段，且所述第四温度大于所述第七温度。
进一步地，第一温度在150℃～300℃之间；第二温度在150℃～300℃之间，且第二温度与第一温度的差值在5℃～100℃之间；第三温度在50℃～200℃之间；第四温度在150℃～300℃之间。
进一步地，第一控制单元11包括第一温度检测模块、第一主控模块和第一谐振模块，其中，第一温度检测模块用于实时检测所述第一发热体的温度，以获取第一温度检测值；第一主控模块用于根据所述第一温度检测值及每个阶段的目标温度输出第一控制信号，其中，第一阶段的目标温度为所述第一温度、所述第二温度，第二阶段的目标温度为所述第五温度；第一谐振模块用于根据所述第一控制信号产生相应的第一交变磁场，且所述第一发热体位于所述第一交变磁场内。该第一谐振模块例如为第一并联谐振电路。
进一步地，第二控制单元12包括第二温度检测模块、第二主控模块和第二谐振模块，其中，第二温度检测模块用于实时检测所述第二发热体的温度，以获取第二温度检测值；第二主控模块用于根据所述第二温度检测值及每个阶段的目标温度输出第二控制信号，其中，第一阶段的目标温度为所述第三温度，第二阶段的目标温度为所述第四温度；第二谐振模块用于根据所述第二控制信号产生相应的第二交变磁场，且所述第二发热体位于所述第二交变磁场内。该第二谐振模块例如为第二并联谐振电路。
当然，在其它实施例中，第一谐振模块还可为第一串联谐振电路，第二谐振模块还可为第二串联谐振电路。
图8是本发明气溶胶产生装置中第一控制单元的电路结构图， 在该第一控制单元中，电阻R2与设置在第一发热体表面的热敏电阻RT1串联组成第一温度检测模块，通过测量热敏电阻RT1上的电压值可以算出热敏电阻RT1的阻值，从而得到第一发热体的第一温度检测值，所检测的第一温度检测值送入第一主控模块。另外，电感线圈L1、电容C1及MOS管Q1组成单管并联谐振电路，工作时，电池电压（BAT+）接入该单管并联谐振电路，电感线圈L1将流过交变电流，该交变电流让电感线圈L1产生交变的电磁场。第一发热体由于置于该电磁场中，由于在第一发热体内的磁滞效应，第一发热体会发热，进一步地，如果第一发热体采用导电材料制成，还会在第一发热体的表面产生感应涡电流使第一发热体发热。 主控模块通过软件算法，根据第一温度检测值控制谐振电路震荡的强度，从而控制第一发热体的温度随着设定的温度曲线变化。
应理解，第二控制单元的电路结构与图8类似，在此不做赘述。

而且，由于处理器在执行计算机程序时可实现本发明实施例所提供的任一种气溶胶产生方法的步骤，因此，可以实现本发明实施例所提供的任一种气溶胶产生方法所能实现的有益效果，详见前面的实施例，在此不再赘述。
