Description

一种温控方法、气雾产生装置及气雾产生系统 技术领域
本发明涉及气雾产生技术领域，具体涉及一种温控方法、气雾产生装置及气雾产生系统。
背景技术
近年来，随着人们对健康的日益关注，人们都意识到吸食传统卷烟对健康有一定的危害，传统卷烟对健康及环境的影响问题开始逐步受到世界各国的重视。烟草生产商均致力于向消费者提供危害更低的烟草制品，近年，加热不燃烧烟制品作为烟草消费的新形式，逐步受到市场的欢迎，正日益被大多数国家的卷烟消费者接受。
目前市面上关于加热不燃烧烟草器具的加热体升温控制程现形式较为单一。一般不论消费者有没有插入雾化烟支，有没有抽吸动作，设计者都采用同一种温度曲线控制方式，容易造成浪费和干烧的风险。此外，这些加热不燃烧烟具的温度曲线也没有根据消费者抽吸行为和与之相匹配的雾化烟草进行单独设计，使消费者的抽吸体验下降。
因此，如何提供一种抽吸体验更好的温控方法成为本领域亟待解决的技术问题。
发明内容
本发明要解决的技术问题是如何提供一种抽吸体验更好的温控方法。
为了解决上述问题，本发明提供了一种温控方法，用于气雾产生装置，气雾产生装置包括检测元件和用于加热气雾产生基质的加热元件，温控方法包括：
在第一阶段，控制加热元件从初始温度升高到第一温度；
在第二阶段，控制加热元件从第一温度下降至第二温度；
在第三阶段，控制加热元件在第二温度恒温运行，若检测元件检测到抽吸，控制加热元件升高到第三温度。
进一步地，在第三阶段，若检测元件在第一预设时长内检测到抽吸，控制加热元件在第二温度恒温第一预设时长后，再控制加热元件升高至第三温度。
进一步地，若检测元件在第一预设时长内未检测到抽吸时，控制加热元件以第二温度 持续运行至第三阶段结束。
进一步地，第一预设时长等于第三阶段开始至气雾产生基质在第二温度下产生的气雾量开始不足的时长。
进一步地，第三阶段中分为若干过程，每个过程独立地设置有预设时长、预设抽吸次数和预设温度，在任意一个过程中，控制加热元件以该过程的预设温度恒温运行，当在该过程的预设时长内检测到该过程的预设抽吸次数时，则结束该过程，升高温度，进入下一个过程。
进一步地，在第三阶段中，相邻的两个过程的预设温度的差值小于或等于15℃。
进一步地，在第三阶段中，在后过程中的预设抽吸次数小于或等于在先过程中的预设抽吸次数。
进一步地，在第三阶段中，若在任意一个过程中，在该过程的预设时长内，检测到的抽吸次数小于该过程的预设抽吸次数，则控制加热元件以该过程预设温度恒温运行至第三阶段结束。
进一步地，当检测到预定的总抽吸次数时，第三阶段结束。
进一步地，在第一温度、第二温度和第三温度要高于气雾产生基质产生气雾的温度，并且低于气雾产生基质燃烧的温度。
进一步地，第一温度和/或第三温度在200～500℃之间，和/或第二温度在180～350℃之间。
进一步地，本发明提供了一种气雾产生装置，包括控制元件、检测元件和用于加热气雾产生基质的加热元件，控制元件用于控制加热元件的能源供应，实现前述的温控方法。
进一步地，检测元件为温度检测元件，用于检测加热元件的温度，通过加热元件温度变化判断是否发生抽吸动作；
或检测元件为气流检测元件，通过气流流动判断是否发生抽吸动作。
进一步地，本发明提供了一种气雾产生系统，包括前述的气雾产生装置及气雾产生基质。
综上所述，本发明中根据消费者抽吸行为控制加热元件的温度变化。在第三阶段中，只有在检测到抽吸时才提升加热元件温度，即可以保证消费者抽吸时气雾的供应量始终满足需求；还可以避免电能和气雾产生基质的浪费。提供了一种更为智能的温控方法，提高了消费者的抽吸体验。

优选地，所述第三阶段ⅲ的持续时间在30秒至120秒之间，预定的总抽吸次数为5～30口，更优选为10～25口。
进一步地，在本发明的一个优选实施例中，如图1所示，温控方法包括：
在第一阶段ⅰ，在第一阶段持续时间内(即t 0至t 1这段时间内)，加热元件从初始温度T 0升高至第一温度T 1；
在第二阶段ⅱ，在第二阶段持续时间内(即t 1至t 2这段时间内)，加热元件从第一温度T 1降低到第二温度T 2；
在第三阶段ⅲ，控制加热元件在第二温度T 2恒温运行，若检测元件在第一预设时长(即t 2至t 3’这段时间内)检测到抽吸，则控制加热元件在t 3’至t 3这段时间内从第二温度T 2升高到第三温度T 3。
在本发明的另一个优选实施例中，如图2所示，若检测元件在第一预设时长(即t 2至t 3’这段时间内)未检测到抽吸，则控制加热元件在t 3’至t 3这段时间内继续保持第二温度T 2运行至第三阶段ⅲ结束。
进一步地，第一预设时长可以设定为第三阶段开始至气雾产生基质在第二温度T 2下产 生的气雾量开始不足的时长。其中，“气雾量开始不足”是指品吸员在第二温度下品吸该气雾产生基质过程中确定的气雾量不满足抽吸需求时的时间。实际中由于不同消费者对于气雾量的需求不同，可以根据实际情况在同一个气雾产生装置内设置多个具有不同第一预设时长的温控系统；或者是生产一系列具有不同第一预设时长的气雾产生装置。优选地，该第一预设时长可以为20至90秒，更优选为30至60秒。
进一步地，传统的加热不燃烧烟具的温度控制方法中，加热曲线都是预先设定，不会根据消费者的抽吸频率发生改变。在消费者抽吸频率较高的情况下，随着加热过程进行，加热元件周围的气雾产生基质中的气雾很快就会释放殆尽，距离加热元件较远的气雾产生基质受热不足，气雾释放量少，释放速率较慢，后期气雾产生基质整体产生的气雾量逐渐不能满足消费者的需求。相对地，如果消费者抽吸频率较低，加热温度还是根据预先设定运行，产生的气雾量超过消费者的需求，则会浪费电能和气雾产生基质。
本申请中通过预定时间内是否达到预设抽吸次数来确定是否升高加热元件的温度，提供了一种更为智能的加热曲线。
在本申请的再一优选实施例中，将第三阶段ⅲ中分为若干过程，每个过程独立地设置有预设时间、预设抽吸次数和预设温度，在任意一个过程中，控制加热元件以该过程的预设温度恒温运行，当在该过程的预设时间内检测到该过程内的抽吸次数达到预设抽吸次数时，则结束该过程，升高温度，进入下一个过程。
具体来说，如图3所示，
在第一阶段ⅰ，在第一阶段持续时间内(即t 0至t 1这段时间内)，加热元件从初始温度T 0升高至第一温度T 1；
在第二阶段ⅱ，在第二阶段持续时间内(即t 1至t 2这段时间内)，加热元件从第一温度T 1降低到第二温度T 2；
在第三阶段ⅲ，包括n个过程，在第一过程ⅲ 1中，控制加热元件以第二温度T 2(同时亦为第一过程ⅲ 1的预设温度T 3.1)恒温运行，若在第一过程的预设时长内(即t 2至t 3.1’这段时间内)检测到第一过程的预设抽吸次数(检测到第一过程的预设抽吸次数的时间点为t 3.1)，立即结束第一过程ⅲ 1，第一过程ⅲ 1的持续时间即为t 2至t 3.1这段时间，随后将温度升高到第二过程的预设温度T 3.2，进入第二过程ⅲ 2；
在第二过程ⅲ 2中，控制加热元件以第二过程的预设温度T 3.2恒温运行，若在第二过程的预设时长内(即t 3.1至t 3.2’这段时间内)检测到第二过程的预设抽吸次数(检测到第二过程的预设抽吸次数的时间点为t 3.2)，立即结束第二过程ⅲ 2，第二过程持续时间即为t 3.1至 t 3.2这段时间，随后将温度升高到第三过程ⅲ 3的预设温度T 3.3，进入第三过程ⅲ 3；
……
在第n-1个过程ⅲ n-1中，控制加热元件以第n-1过程ⅲ n-1的预设温度T 3.n-1恒温运行，若在第n-1过程的预设时长(即t 3.n-2至t 3.n-1’这段时间)内检测到第n-1过程的预设抽吸次数(检测到第n-1过程的预设抽吸次数的时间点为t 3.n-1)，立即结束第n-1过程ⅲ n-1，第n-1过程持续时间即为t 3.n-2至t 3.n-1这段时间，随后将温度升高到第n过程ⅲ n的预设温度T 3.n，进入第n过程ⅲ n；
在第n过程ⅲ n中，控制加热元件以第n过程ⅲ n的预设温度T 3.n恒温运行，检测到预定的总抽吸次数，结束第三阶段ⅲ。
进一步地，每一个过程中的预设时长和预设抽吸次数可以相同也可以不同，可以根据具体的气雾产生基质气溶胶释放情况设定，预设抽吸次数优选为1～10口，更优选为2～5口，预设时长优选为3～30秒，更优选为5～20秒。进一步地，在第三阶段中，随着抽吸时间增加，加热元件周围的气雾产生基质中的气雾释放殆尽，距离加热元件较远的气雾产生基质受热不足，气雾释放量少，释放速率较慢，为了保证每次抽吸的气雾量满足需求，在后过程中的预设抽吸次数要小于或等于在先过程中的预设抽吸次数。
进一步地，为了保证气雾产生基质中气雾释放量的一致性，前后两个过程的预设温度的差值小于或等于15℃。
进一步地，在本发明的又一优选实施例中，在前述任意一个过程中，若在该过程的预设时长内，检测到的抽吸次数小于该过程的预设抽吸次数，则控制加热元件以该过程预设温度恒温运行至第三阶段结束。
举例来说，如图4所示，在第三阶段ⅲ，在第一过程ⅲ 1中，控制加热元件以第二温度T 2恒温运行，若在第一过程ⅲ 1的预设时长内(即t 2至t 3.1’这段时间内)检测到第一过程的预设抽吸次数，立即结束第一过程ⅲ 1，第一过程ⅲ 1持续时间即为t 2至t 3.1这段时间，随后将温度升高到第二过程ⅲ 2的预设温度T 3.2，进入第二过程ⅲ 2；
在第二过程ⅲ 2中，控制加热元件以第二过程ⅲ 2的预设温度T 3.2恒温运行，若在第二过程ⅲ 2的预设时长内(即t 3.1至t 3.2’.这段时间内)未检测到第二过程的预设抽吸次数，则控制加热元件以第二过程ⅲ 2预设温度T 2恒温运行至第三阶段ⅲ结束。此时，第三阶段只包括两个过程。
结合上述两个优选实施例可以理解的是，前述的“第三阶段，包括n个过程”中n大于等于1，n的上限没有特殊限定，以达到预定的总抽吸次数所经历的实际的过程数目确 定。
采用上述技术方案，在第三阶段中，根据抽吸频率来控制加热元件的温度逐步上升，当抽吸频率较高的情况下，加热元件温度上升较快，产生的气雾量保持较高的水平；当抽吸频率较低时，加热元件温度不上升或者上升较慢，产生的气雾保持在较低的水平，避免浪费。
在本申请中通过消费者抽吸来控制温度曲线变化，既能保证消费者连续抽吸时气雾产生基质产生的气雾量满足消费者需求，在消费者抽吸频率较低时，更节约电能，避免气雾产生基质浪费。
进一步地，本发明还提供了一种气雾产生装置，包括控制元件、检测元件和用于加热气雾产生基质的加热元件，控制元件用于控制加热元件的能源供应，实现前述任一种温控方法。
进一步地，检测元件可以为现有技术中已有的任何检测抽吸动作的检测元件，例如，可以为温度检测元件，用于检测加热元件的温度，通过加热元件温度变化判断是否发生抽吸动作，当温度检测元件检测到加热元件的温度突然显著下降时，判断为一次抽吸动作。
可选地，检测元件还可以为气流检测元件，通过气流流动判断是否发生抽吸动作。
进一步地，本发明还提供了一种气雾产生系统，包括前述的气雾产生装置及气雾产生基质。
本发明中根据消费者抽吸行为控制加热元件的温度变化。在第三阶段中，只有在检测到抽吸时才提升加热元件温度，即可以保证消费者抽吸时气雾的供应量始终满足需求；还可以避免电能和气雾产生基质的浪费。提供了一种更为智能的温控方法，提高了消费的抽吸体验。
虽然通过参照本发明的某些优选实施方式，已经对本发明进行了图示和描述，但本领域的普通技术人员应该明白，以上内容是结合具体的实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。本领域技术人员可以在形式上和细节上对其作各种改变，包括做出若干简单推演或替换，而不偏离本发明的精神和范围。
