 附图说明
下面将结合附图及实施例对本发明作进一步说明，附图中：
图1是本发明一实施例的电子烟防干烧温控方法流程示意图；
图2是本发明另一实施例的电子烟防干烧温控方法流程示意图；
图3是本发明一实施例的防干烧温控电子烟的结构框图；
图4是本发明另一实施例的防干烧温控电子烟的结构框图。
 本发明的实施方式
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。
参考图1，本发明一实施例的电子烟防干烧温控方法，包括以下步骤：
S1、电子烟的供电装置在检测获取雾化装置的干烧信号后，将雾化装置中发热体的加热温度从原先的第一恒温加热温度降至第二恒温加热温度。
其中，第一恒温加热温度和第二恒温加热温度均是预先设定在供电装置的控制电路或对应的恒温加热控制单元中。通常情况下，电子烟的供电装置启动后，控制发热体进行加热并以第一恒温加热温度对烟液进行加热雾化。在供电装置无获取干烧信号时，发热体仍以第一恒温加热温度进行加热。
供电装置在获取干烧信号后，控制发热体降低加热温度，以第二恒温加热温度进行加热。对于降低恒温加热温度，可以通过调节发热体的电阻值等来实现。
第二恒温加热温度为低于第一恒温加热温度的加热温度，且为对雾化装置以及人体都安全的温度。并且，第二恒温加热温度低于干烧温度阈值，这样既可以解决干烧问题，还可以保持较低的温度继续加热，尤其是雾化装置新注入浓稠烟液立即抽吸时，避免频繁的启停，不损伤雾化装置。
供电装置检测获取的干烧信号可以通过多种信息获得。例如，发热体的电阻值变化（判断是否达到干烧阻值阈值）、发热体的温度值（判断是否达到干烧温度阈值）等等。
S2、发热体以第二恒温加热温度继续加热，直至收到供电装置的停止信号。
其中，在发热体以第二恒温加热温度继续加热的同时，不影响烟液导入并浸润发热体，当使用者再次抽吸时，由于雾化液已浸润发热体，可正常抽吸电子烟，不再产生干烧警告。在收到供电装置的停止信号后，发热体停止加热。
S3、供电装置再次启动时，发热体以第一恒温加热温度进行加热；在供电装置检测获取干烧信号后，返回步骤S1。
在上述步骤S1-S3的循环过程中，供电装置在设定时间内，检测获取雾化装置的干烧信号的次数达到设定次数时，供电装置控制发热体停止加热，以此表明雾化装置中存在液量不足或耗尽的情况。
设定时间和设定次数具体可根据雾化装置中的容量以及结合其每次雾化量的情况设置。对于上述在设定时间内检测获取的雾化装置的干烧信号的次数达到设定次数的情况，供电装置中对应的默认模式为非新注入浓稠烟液并立即抽吸的情况，即：当供电装置在设定时间内检测获取雾化装置的干烧信号的次数达到设定次数时，排除了是新注入浓稠烟液并立即抽吸的情况，从而对应是属于雾化装置中存在液量不足或耗尽的情况，因此供电装置控制发热体停止加热。
进一步地，对于供电装置上设有显示屏等显示模块时，供电装置可将雾化装置中液量不足或耗尽、或者新注入浓稠烟液流通不畅等的信息通过其显示屏示出，示出的方式可以是文字、液量线、亮灯和声音等各种方式中至少一种，以此告知使用者。
参考图2，本发明另一实施例的电子烟防干烧温控方法，包括以下步骤：
S1、电子烟的供电装置在检测获取雾化装置的干烧信号后，将雾化装置中发热体的加热温度从原先的第一恒温加热温度降至第二恒温加热温度。
其中，第一恒温加热温度和第二恒温加热温度均是预先设定在供电装置的控制电路或对应的恒温加热控制单元中。通常情况下，电子烟的供电装置启动后，控制发热体进行加热并以第一恒温加热温度对烟液进行加热雾化。在供电装置无获取干烧信号时，发热体仍以第一恒温加热温度进行加热。
供电装置在获取干烧信号后，控制发热体降低加热温度，以第二恒温加热温度进行加热。第二恒温加热温度为低于第一恒温加热温度的加热温度，且为对雾化装置以及人体都安全的温度。
第二恒温加热温度低于干烧温度阈值，这样既可以解决干烧问题，还可以保持较低的温度继续加热，避免频繁的启停，不损伤雾化装置。
供电装置检测获取的干烧信号可以通过多种信息获得。例如，发热体的电阻值变化（判断是否达到干烧阻值阈值）、发热体的温度值（判断是否达到干烧温度阈值）等等。
S2、发热体以第二恒温加热温度继续加热，直至收到供电装置的停止信号。
本实施例中，在收到供电装置的停止信号后，发热体按设定的持续时间继续以第二恒温加热温度加热，这样可以使烟液顺利导入并浸润发热体（特别对于较为浓稠的烟液新注入雾化装置内并立即抽吸时），以便下次供电装置启动后发热体上有足够的烟液先被加热雾化。持续时间可根据实际情况设置。
S3、供电装置再次启动时，发热体以第一恒温加热温度进行加热。在供电装置检测获取干烧信号后（再次干烧），控制发热体停止加热，以此发出雾化装置中存在液量不足或耗尽等的警报。
进一步地，对于供电装置上设有显示屏等显示模块时，供电装置可将雾化装置中液量不足或耗尽、或者新注入浓稠烟液流通不畅等的信息通过其显示屏示出，示出的方式可以是文字、液量线和亮灯等各种方式中至少一种，以此告知使用者。
本发明的电子烟防干烧温控方法可由防干烧温控电子烟实现，如图3、4所示，该防干烧温控电子烟可包括雾化装置10、供电装置20、第一恒温加热控制单元30和第二恒温加热控制单元40。供电装置20连接雾化装置10，为其供电及控制其加热工作。第一恒温加热控制单元30与供电装置20和雾化装置10连接，第二恒温加热控制单元40与供电装置20和雾化装置10连接。
其中，供电装置20通过第一恒温加热控制单元30控制雾化装置10的发热体以第一恒温加热温度进行加热。在电子烟的正常使用时，供电装置20启动后，均是通过第一恒温加热控制单元30控制发热体以第一恒温加热温度进行加热。
供电装置20在检测获取雾化装置10的干烧信号后，通过第二恒温加热控制单元40控制发热体以第二恒温加热温度进行加热。第二恒温加热温度低于第一恒温加热温度，通过控制降低发热体的加热温度，避免其进行持续干烧，解决干烧问题。
对于干烧信号的检测获取，可通过雾化装置20内设置的电阻丝或温度传感器，根据电阻丝的电阻值变化（判断是否达到干烧阻值阈值）或温度传感器检测到的温度变化（判断是否达到干烧温度阈值）判断是否发生干烧。
在一实施例中，如图3所示，供电装置20设有检测单元21。检测单元21检测到供电装置20在设定时间内获取雾化装置的干烧信号的次数达到设定次数时，供电装置20控制发热体停止加热，以此表明雾化装置10中存在液量不足或耗尽的情况。该实施例的防干烧温控电子烟可用于实现上述图1所示的一实施例的电子烟防干烧温控方法。
在另一实施例中，如图4所示，供电装置20设有加热控制单元22。供电装置20向发热体发出停止信号后，加热控制单元22控制发热体按设定的持续时间继续以第二恒温加热温度加热。较于立刻停止加热的情况，发热体按持续时间继续以第二恒温加热温度加热可以使烟液顺利导入并浸润发热体（特别对于较为浓稠的烟液），以便下次供电装置启动后发热体上有足够的烟液先被加热雾化。持续时间可根据实际情况设置。该实施例的防干烧温控电子烟可用于实现上述图2所示的另一实施例的电子烟防干烧温控方法。
综上可知，本发明的电子烟防干烧温控方法及防干烧温控电子烟，当电子烟检测到雾化装置干烧时，不立即停止加热，而是降低恒定加热温度，使电子烟不烧焦烟液且不损伤雾化装置。降低的温度可持续加热烟液，使烟液能顺利导到发热体；当使用者再次抽吸时，由于烟液已浸润发热体，可正常抽吸电子烟，不再产生干烧告警。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
