Description

一种电子烟的控制方法及电子烟 技术领域
本发明涉及电子烟技术领域，尤其涉及一种电子烟的控制方法及电子烟。
背景技术
传统吸烟方式是利用明火点燃烟草，烟草燃烧产生烟雾以供吸烟者吸食。烟草燃烧产生的烟雾通常会含有上千种有害物质，因而，传统吸烟方式不但给吸烟者造成严重的呼吸系统疾病，还容易带来二手烟危害。为解决吸烟方式中烟草燃烧产生较多有害物质的技术问题，现有技术提出了雾化电子烟及电子烤烟两种解决方案。
其中，雾化电子烟通过雾化烟液形成烟雾，以供吸烟者吸食，雾化电子烟虽然克服了传统卷烟的以上不足，能够在一定程度上满足消费者对烟草的依赖。但电子烟的烟液是由香精香料调配而成，并不是真正的卷烟产品，其烟味淡，缺乏烟草的芳香，而不能被消费者广泛地接受。其中，电子烤烟主要为低温电子烤烟，采用低温(100摄氏度左右)不燃烧方式加热烟丝，由于其加热温度较低，所以加热产生的危害物质少，但烟雾量明显不足。而若采用高温对烟草进行加热，则容易将烟草考黑，碳化，且热量分布不均，容易产生部分烟草已经碳化而另一部分烟草温度还不足的问题，因而也不可避免的会产生较多的有害物质。
且现有电子烟，没有有效的用户提醒机制，即没有提示信息可以提示用户何时进行更换烟草，给用户带来极大的不变，造成极差的用户体验效果。

实施例一：
参考图1，本发明实施例提供了一种电子烟的控制方法，包括：
S1、在检测到烟草加热信号时，控制烟草加热元件进入加热状态以对烟草进行烘烤；
S2、若检测到吸烟信号，则记录吸烟信号的持续时间，且当吸烟信号的持续时间累计达到预设时间时发出提示信息。
需要说明的是，该提示信息，可以是LED灯亮或者闪光，或者发出声音提示，只要能对用户进行提示即可，具体不做限定。
关于步骤S1：
步骤S1的目的是在检测到烟草加热信号时，即对烟草进行预热处理。烟草插入电子烟后会触发烟草加热信号，而烟草加热信号会控制烟草加热元件工作，以对烟草进行烘烤。
步骤S1具体包括：在检测到烟草插入电子烟腔体而产生的烟草加热信号 时，控制烟草加热元件进入加热状态以对烟草进行烘烤。
其中，烟草加热信号的触发方式有多种，例如，在烟草插入电子烟腔体后，烟草挤压电子烟腔体中的压力传感器，压力传感器检测到压力变化则产生烟草加热信号；在烟草插入电子烟腔体后，电子烟腔体中的电容传感器检测到电容变化则产生烟草加热信号；在烟草插入电子烟腔体后，烟草挤压电子烟腔体中的轻触开关，则触发轻触开关发送烟草加热信号。
因此可选的，所述烟草加热信号为压力传感器在烟草插入电子烟腔体后检测到压力变化时产生的信号，或者所述烟草加热信号为电容传感器在烟草插入电子烟腔体后检测到电容变化时产生的信号，或者所述烟草加热信号为轻触开关在烟草插入电子烟腔体后受到挤压时产生的信号。
可选的，压力传感器采用美国飞思卡尔公司生产的型号为MPX5100的压力传感器。可以理解的，电子烟中还可设置其他能够检测烟草插入的传感器，在此不做限制。
在本实施例中，步骤S1具体包括：在检测到烟草插入电子烟腔体而产生的烟草加热信号时，控制烟草加热元件进入加热状态，以第一预设功率对烟草进行烘烤。其中，第一预设功率可以为全功率或一半功率，可以根据需求设定。
为了避免预热过度，同时又能保证预热充分，一般建议预热升温到200℃—260℃的时候停止以第一预设功率的预热，此时用户可以正式吸烟了。在预热完成后，会通过发光单元提示用户使用。在一个可选的实施方式中，步骤S1还包括：当所述烟草加热元件以第一预设功率工作至预设的烟草预烤时间时，控制第一发光单元发光，以提示用户使用。
为了更直观的提醒用户电子烟的状态以及是否可以开始吸烟，可以在预热时第二发光单元发红光提醒，在停止预热可以吸烟的时候将第二发光单元的红光熄灭，且第一发光单元发绿光。因此在另一个可选的实施方式中，步骤S1还包括：在控制所述烟草加热元件进入加热状态的同时，还控制第二发光单元发红光，在发光时间达到预设的烟草预烤时间时控制所述第二发光单元切换到熄灭状态，并控制第一发光单元发绿光，以提示用户使用。
可以理解的是，当第一预设功率工作的时间没有达到烟草预烤时间时，用户无法输入吸烟信号，此可以通过开关将吸烟信号的输入路径断开即可；或者 可以输入吸烟信号，但是该吸烟信号无效，即不会对此吸烟信号进行任何处理。其中，所述吸烟信号为用户吸烟时气流传感器检测到用户吸烟动作而产生的信号。可以理解的是，所述吸烟信号可以为用户触发吸烟按键开关而产生的信号，因此，所述吸烟信号的产生方式在此不作具体限定。
其中，烟草预烤时间建议为0.5分钟至1分钟。当然也可以根据停止预热时的温度和第一预设功率确定。例如假定设定的停止预热时的温度为250℃，起始加热的温度默认为25℃，则需要升温200℃。根据热能计算法公式计算得到热量Q＝C*M*ΔT，C为空气比热容，ΔT为升温值，此处即为200℃，M为空气质量，可以根据估算的加热空间的体积估算M。再Q＝P*t，根据即可估算得到烟草预烤时间t＝Q/P，P为加热功率，即第一预设功率。
在已经进行使用提示后，需要等待用户吸烟，因此为了在用户吸烟之前的等待时间内保持烟草的预热效果，可以将功率降低后对烟草进行加热保温。因此可选的，步骤S1还包括：当所述烟草加热元件以第一预设功率工作至烟草预烤时间时，控制所述烟草加热元件以第二预设功率工作；所述第二预设功率小于所述第一预设功率。其中，加热保温建议温度为120℃至200℃。
关于步骤S2：
在一个可选的实施方式中，步骤S2具体包括：若检测到吸烟信号，则控制烟液雾化元件进入加热状态以及记录吸烟信号的持续时间，以使所述烟液雾化元件及所述烟草加热元件同时工作，且将烟液雾化元件雾化烟油产生的烟雾流入烟草加热元件所烘烤的烟草区域时对所述烟草进行蒸，以与所述烟草加热元件烘烤烟草产生的烟雾混合而产生混合烟雾，且当所述吸烟信号的持续时间累计达到预设时间时发出提示信息。
其中，当检测到吸烟信号的持续时间累计达到预设时间时(该预设时间例如可以设置为10分钟，或者其他的数值，用户可以根据自己的喜好进行设置，如用户喜欢抽浓一点的味道，可以设置时间短一些例如5分钟，反之亦可，具体不做限定)，此时所述烟草的味道已经变淡了，为了提高用户的体验，此时可以发出提示信息，该提示信息指示用户更换所述烟草，为用户提供更优的体验。
其中，所述吸烟信号为用户吸烟时气流传感器检测到用户吸烟动作而产生 的信号。可选的，气流传感器为杭州展业兴电子有限公司的生产型号为S087的气流感应器。
理论上，在步骤S2中烟草加热元件和烟液雾化元件同时工作时，对于烟草加热元件的加热功率可以不做限制，既可以在用于加热保温时的第二预设功率工作，也可以在第二预设功率的基础上提升，以实现在吸烟时尽量提升电子烟模拟真烟的口感，因此可选的，步骤S2中，当接收到吸烟信号时烟草加热元件以第一预设功率工作。
为了尽量模拟吸烟的过程，在接收到烟草加热信号之后的预设吸烟有效时间之内，一旦预热好用户即可吸烟，且无论用户任意两次吸烟的时间间隔多少，在等待吸烟的过程中烟草加热元件都保持以第二预设功率工作以实现加热保温。但为了避免预热好之后一直等待下去，即防止电子烟预热后长期处于等待吸烟的状态。因此可选的，步骤S2还包括：在检测到所述烟草加热信号后的预设吸烟有效时间内，若未检测到吸烟信号，则控制所述烟草加热元件停止工作。
其中，预设吸烟有效时间可以根据平常用户每次吸烟的总时长预先设定，预设吸烟有效时间一般建议为3至8分钟的一个数值，可以在电子烟出厂时设定，也可以提供一个用户设定方案。例如，可以提供代表时间增加的加按键和代表时间减小的减按键，如果用户同时按下加按键和减按键，则会触发电子烟进入设定状态，在设定状态下，每按压一次加按键或者减按键，预设吸烟有效时间会以预设步长进行增加或者减小，设定好之后，用户再次同时按下加按键和减按键，即可保存此次的预设吸烟有效时间的设定信息。当然此设定方案必须在步骤S1之前或者步骤S2之后才能执行。
在另一个可选的实施方式中，为了防止电子烟预热后长期处于等待吸烟的状态，还可在第一发光单元工作后设置一个预设时间。因此步骤S2具体包括：在所述第一发光单元工作的预设时间内，若检测到吸烟信号，则控制烟液雾化元件进入加热状态，以使所述烟液雾化元件及所述烟草加热元件同时工作，烟液雾化元件雾化烟油产生的烟雾流入烟草加热元件所烘烤的烟草区域时对所述烟草进行蒸，以与所述烟草加热元件烘烤烟草产生的烟雾混合后排出以供用户吸食。步骤S2还包括：在所述第一发光单元工作的预设时间内，若从未检 测到吸烟信号，则控制所述烟草加热元件和所述第一发光单元停止工作。其中，预设时间一般建议为3-8分钟的一个数值，可以在电子烟出厂时设定，也可以提供一个用户设定方案。
可以理解的是，在烟草加热元件和第一发光单元停止工作后，不再检测吸烟信号，或者即使检测吸烟信号，也不再对该吸烟信号进行任何处理。因此可选的，步骤S2还包括：在所述第一发光单元停止工作后，若检测到吸烟信号，则所述烟液雾化元件不工作。
下面结合附图2-5，说明本发明实施例中电子烟的控制方法的电路实现方案。

需要说明的是，当烟草插入电子腔体后，触发K1发送信号给微处理器U，从而U控制烟草加热元件B1给烟草加热(可以全功率或者一半功率)，同时微处理器U开始计时，当烟草加热元件B1累计给烟草加热预设时间时，所述微处理器U控制所述LED1不断闪烁或者亮灯，以提示用户更换烟草，以避免烟味长时间使用而使味道淡的问题。
