本发明涉及用于加热器的电阻检测***和电阻检测方法。
 背景技术
低温加热烟又称加热不燃烧烟，以卷烟形式比较多见，但与传统的燃烧产生烟气的卷烟不同，以“加热不燃烧”为思路设计的低温加热烟，能使烟叶刚好加热到足以散发出味道的程度而不点燃烟叶，使一手烟和二手烟中的有害物质大幅减少。PCT/EP2010/006598公开了一种发烟***，加热器包括在电绝缘衬底上的多个导电轨迹，所述电绝缘衬底是刚性的，并且布置成***到所述形成浮质的衬底中，导电轨迹具有这样的电阻温度系数特征，所述电阻温度系数特征使得所述多个导电轨迹能够既用作电阻加热器又用作温度传感器。在实际的生产过程中，加热器的一致性不够高，使得每个加热器的电阻温度系数特征具有差别，给加热器使用过程中的温度控制带来困难。

 本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。相反，当元件被称作“直接在”另一元件“上”时，不存在中间元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的。实施例附图中各种不同对象按便于列举说明的比例绘制，而非按实际组件的比例绘制。
本发明实施例所称“气溶胶生成物质”指发烟物质，是经加热或燃烧可以产生气味和/或尼古丁和/或烟气的物质，即可被雾化的物质，即烟料。烟料可以是固态、半固态和液态。固态烟料因为透气性、组装和制作等方面的考虑，经常加工成薄片状，因此又俗称为薄片，丝状薄片也称为薄片丝。本发明实施例所讨论的烟料可为天然的或人工合成的烟液、烟油、烟胶、烟膏、烟丝、烟叶等，例如，人工合成的烟料含有甘油、丙二醇和烟碱等。所述烟液为液体，所述烟油为油状，所述烟胶为凝胶状，所述烟膏为膏状，所述烟丝包括天然的或人造的或萃取加工过的烟丝，所述烟叶包括天然的或人造的或萃取加工过的烟叶。烟料可以在被其它物质封存的形式下被加热，如保存在可遇热降解的包装中，例如微胶囊中，加热后所需挥发性物质从降解或有孔隙的封存包装中导出。
本发明实施例所述的烟料可以含有烟碱，也可以不含有烟碱。含有烟碱的烟料可以包括天然烟叶制品，以烟碱为原料制成的烟液、烟油、烟胶、烟膏、烟丝、烟叶等中的至少一种。烟液为水状，烟油为油状，烟胶为凝胶状，烟膏为膏状，烟丝包括天然的或人造的或萃取加工过的烟丝，烟叶包括天然的或人造的或萃取加工过的烟叶。不含有烟碱的烟料主要含有香味物质，例如香料，即可被雾化以起到模拟吸烟过程又起到戒烟等目的。在一实施例中，所述香料包括薄荷油。所述烟料还可包括其他添加剂，例如甘油和/或丙二醇。
本发明实施例所述的“气溶胶生成制品”指包含烟料，能够通过加热产生气溶胶，例如烟气或雾气的产品，例如香烟、烟弹或烟支，优选为一次性使用的制品。所述气溶胶生成制品本身不能够提供电能。
***式加热器被配置为***低温加热烟内部进行加热，是加热不燃烧烟技术领域比较最常见的加热器形态，本身具有一定强度且体积小。筒状加热器被配置为容纳低温加热烟，对其进行外部加热。
现有技术中通常基于电阻温度系数来实现加热器的温度控制，较好情况下，导体的电阻与温度之间的关系是基本线性的。但是导电轨迹在较小的加热器体积上通常呈细线分布，局部的差异都会对电阻特性具有较大影响，实际制备得到的加热器，由于使用的材料、工艺等各方面因素的影响，初始电阻值和电阻温度系数均难以做到一致性很好，如果直接使用固定的电阻温度系数特征进行温度控制将势必导致加热温度控制的不准确，并直接影响口感。
本发明实施例提供一种电阻检测***，图1示出了本发明实施例电阻检测***的结构，主要包括温度探测单元100、电源200、电阻测量单元300、控制单元400，用于对加热器500（图中未示出，参见图4）的电阻进行检测，所述加热器500优选为***式加热器，现分别就其结构和功能予以介绍。由于加热器500的电阻值随温度的升高而持续变大或者持续变小，对加热器500供电的情况下加热器500到达预设温度时其电阻值也升高或者降低到一个目标值，温度探测单元100检测器温度值，电阻测量单元300检测电阻值，本发明电阻检测***在同时检测加热器温度和电阻的情况下获取该目标值并予以记录，用于后续的加热控制。
温度探测单元100是用于检测所述加热器500实际发热温度的核心部件，包括至少一个温度传感器110，当所述加热器500固定并使得至少一个温度传感器110对准所述加热器500时，电阻检测***即可开始工作。例如，所述加热器500在通电的情况下温度持续升高，温度传感器110即可检测其实际发热温度；由于加热器500实际使用时也是***低温加热烟内部进行加热，此种结构的温度探测单元100的检测结果接近真实使用情形下加热器500的温度状况。
电源200，结合图1可知，用于将电能供给到所述加热器500；电流、电压、脉冲频率等供电方式可以与实际的电加热器具不一样，也可以模拟实际的电加热器具的供电方式以达到更接近真实状况的效果；电源200的形式可以多样，例如，直接检测成品或者半成品的加热器500的电阻值，可以直接使用成品或者半成品的电源200对加热器500进行供电，如果检测对象时单个的加热器500，直接将其连接至外接电源200即可。
电阻测量单元300，结合图1可知，与所述加热器500电连接，测量接入所述加热器500的电压和电流值，换算得到电阻值，该电压和电流值越接近实际值其所测量得到的电阻值越接近准确。由于加热器500的电阻值随温度的升高而持续变大或者持续变小，对加热器500供电的情况下加热器500到达预设温度时其电阻值也升高或者降低到一个目标值。
控制单元400，结合图1可知，分别与所述温度探测单元100和所述电阻测量单元300信号连接，所述加热器500在所述电源200的供电下升温，由于加热器500置于温度探测单元100上，温度传感器110检测到的温度也随之升高，如果不考虑温度传感器110的温度检测滞后或者检测误差，温度传感器110检测到的温度即为与所述加热器500表面的实际温度，如果考虑温度传感器110的温度检测滞后或者检测误差，可以通过软件算法对其进行修正或者补偿，当所述温度探测单元100检测到所述加热器500达到预设温度，调取电阻测量单元300此时检测到的电阻值，并记录在此温度下所述加热器500的电阻值。此电阻值即可以用于后续加热控制的目标值，例如，一款加热不燃烧烟的最适加热温度为300℃，加热器500的电阻值随温度的升高而持续变大，所述加热器500加热至300℃时的电阻值为R，则实际使用和控制过程中，测量所述加热器500的电阻值升高到R时说明已经到达最适加热温度，降低功率或者停止供电；测量所述加热器500的电阻值低于R时说明还没有已经到达最适加热温度，继续供电。
在本发明电阻检测***的另一实施例中，所述温度探测单元100中包括用于测量所述加热器500同一位置或者区域温度的至少两个温度传感器110。该位置或者区域指温度探测单元100在被测对象表面的检测范围，只有在这个检测范围红外信号才会被温度探测单元100吸收以转换为电信号。例如同一位置位于与所述加热器500的长度延伸方向垂直的同一平面，同一区域位于与所述加热器500的长度延伸方向的高度范围，所述加热器500在该同一位置或者区域的温度应该基本相等，多个此种方式设置的温度传感器110可以用于相互之间的校准。类似的，所述温度探测单元100中包括用于测量所述加热器500不同位置或者区域温度的至少两个温度传感器110。沿所述加热器500的长度延伸方向一字排列，也可以呈螺旋形排列。所述加热器500不同位置或者区域的温度应该存在一定差异，多个此种方式设置的温度传感器110可更准确的反应出所述加热器500上的温度分布，可以用于更准确的加热温度控制，实现更好的出烟口感和吸味。
在本发明电阻检测***的另一实施例中，所述腔体110的形状与所述加热器500相适配。参见图2，所述加热器500为长条形的棒状或者针状，腔体110的尺寸略大于所述加热器500，便于所述加热器500***有不会存在过大的间隙。当然，所述加热器500为其他形状，例如，片状等，腔体110的形状也应该与其适配。
在本发明电阻检测***的另一实施例中，所述预设温度至少包括第一预设温度和第二预设温度，例如，一款加热不燃烧烟的最适加热温度为300℃～330℃，加热器500的电阻值随温度的升高而持续变大，第一预设温度即可以定为300℃，第二预设温度即可以定为330℃，所述控制单元400分别记录与此温度对应的所述加热器500的第一电阻值和第二电阻值。所述加热器500加热至300℃时的第一电阻值为R1，所述加热器500加热至330℃时的第二电阻值为R2，很明显R1＜R2，实际使用和控制过程中，测量所述加热器500的电阻值升高到R1时说明已经到达最适加热温度区间，继续供电或者降低功率供电，使得温度继续升高；测量所述加热器500的电阻值升高到R2时说明已经到达温度上限，降低功率或者停止供电，使得温度降低；测量所述加热器500的电阻值降低到R1时说明已经到达最适温度下限，开始供电或者提高功率供电。当然，如果加热器500的电阻值随温度的升高而持续变小，则R1＞R2，维持最适加热温度的办法类似，依然是使得所述加热器500的电阻在R1和R2之间，只是在具体控制时电阻降低至R2时需要降低功率或者停止供电，等待电阻升高至R1时需要开始供电或者提高功率供电。
优选的，如果一款加热不燃烧烟的加热控制过程中需要更多的目标值，以更加精准的温度控制，可以设置更多的预设温度T1、T2、T3、T4……，以及与这些预设温度对应的电阻值R1、R2、R3、R4……，构成所述加热器500的一组离散的温度电阻关系，任意选择其中的一个或者两个均可以使用前述实施例中的方式予以实施温度控制。
优选的，所述温度探测单元100实时检测所述加热器500的温度，所述电阻测量单元300实时检测所述加热器500的电阻值，这样就构成所述加热器500的线型的温度电阻关系，所述控制单元400记录所述加热器500的电阻与温度之间的关系，可以根据所述加热器500任意时刻的电阻值确定其加热温度，实现更加灵活多样的控制。
在本发明电阻检测***的另一实施例中，温度探测单元100的腔体110内设置至少两个温度传感器110，将这些不同温度传感器110检测得到的温度值组合使用或者选择性使用，以得到更加准确的所述加热器500的温度值。例如，同时有两个或者两个以上的温度传感器110检测所述加热器500同一位置或者区域的温度，如果这些温度传感器110全部对准良好，检测到的温度应该基本相等，不会出现太大偏差，但是检测过程中时情况不会每次都如此理想，因此通过使用平均温度的方式，可以将此种情形带来的误差降低可控范围。
再例如，每一款加热不燃烧烟都有其适合的加热温度，如果加热温度过高，被加热的烟草制品会出现过度的热裂解，不仅会释放出更多的有害物质，还影响吸烟口感。相反，如果加热温度过低，又不足以释放出足够的被吸食成分，例如香味成分和盐碱等，影响吸烟体验。因此检测所述加热器500的最高温度、最低温度可以作为后续控制的重要参考。当然，平均温度、最高温度、最低温度也可以组合使用，例如所有检测到的温度中去掉最高值和最低值，剩下的取平均值。可以根据实际的加热器500的类型和温度分布特点，将各温度传感器110检测到的温度，选取适合的组合方式予以使用。上述检测温度的使用方式只是示例性的，没有包括具体使用过程中的全部实例，只要这些检测温度的单独使用或者组合使用不存在矛盾，都应当认为是本说明书记载的范围。
优选的，所述腔体110内设置至少两个温度传感器110，如果其中两个温度传感器110检测所述加热器500不同位置的温度值，两者之间会存在一个大体固定的温差值，如果两个温度传感器110检测所述加热器500同一位置的温度值，检测到的温度应该基本相等。当其中两个温度传感器110的位置固定，其检测所述加热器500的温度差值也大体固定，因此可以根据实际情况确定一个阈值，如果其中两个温度传感器110检测到的温度差值小于此阈值，说明检测正确，记录在此温度下所述加热器500的电阻值；否则，说明检测错误，重新检测。
在本发明电阻检测***的另一实施例中，所述电阻检测***包括大于两个的温度探测单元100和大于两个的电阻测量单元300，其可以共用同一个控制单元400，也可以分别连接一个控制单元400，这样就形成了多组检测子***并行的情形，此种设置可以实现同时连接多个加热器500，实现对多个加热器500的批量检测。
在本发明电阻检测***的另一实施例中，所述温度传感器110为红外温度传感器，它的敏感元件与被测对象加热器500之间互不接触，是非接触式温度传感器，也称为红外测温仪。这种温度传感器可用来测量运动物体、小目标和热容量小或温度变化迅速（瞬变）对象的表面温度，也可用于测量温度场的温度分布。本实施例中，加热器的温度变化范围位于所述红外温度传感器的量程范围内，量程也就是测温范围，选择红外温度传感器时一定要注意到它的量程，只有选择了适合的量程才能进行测量。另外，要注意传感器的类型和尺寸以实现温度的准确测量，例如，红外温度传感器的距离系数D：S是红外探头的一个重要参数，即测温仪探头到目标之间的距离D与被测目标直径S之比。在被测目标尺寸确定的情况下，可以确定一个探头到目标之间的合适距离范围；同时传感器的尺寸不能选择过大也不能太小，特别是对于固定焦距的测温仪，在光学***焦点处为光斑最小位置，近于和远于焦点位置光斑都会增大，要根据加热器500的尺寸选择传感器的尺寸，避免测量光斑大于传感器的尺寸的情况出现。选择红外温度传感器时，还要确定光学分辨率、确定波长范围、确定响应时间、信号处理功能等，例如被测物体的材料确定测量时的波长范围，另外，需要特别考虑温度、气氛、污染和干扰等因素对性能指标的影响，以确定修正方法增加测量精度。优选的，在使用电阻检测***时，加热器500设置在所述红外温度传感器110的最佳测量位置，例如使用具有光学辅助定位单元的红外温度传感器，最佳测量位置最优选为其最小光斑位置，为了能在接近和远离焦点的距离上准确测温，被测目标尺寸应大于焦点处光斑尺寸，实现的对加热器500表面温度的最精准测量。
在本发明电阻检测***的另一实施例中，温度探测单元100对筒状加热器进行温度检测，例如直接测量筒状加热器的外壁温度，或者将温度探测单元100对准筒状加热器的内壁，即可完成对容纳腔中温度的检测。同时测量接入所述筒状加热器的电压和电流值，换算得到电阻值，该电压和电流值越接近实际值其所测量得到的电阻值越接近准确。具体的电阻测量过程和控制单元400的工作过程与前述实施例相同，在此不再赘述。
在本发明电阻检测***的另一实施例中，还包括用于固定所述加热器500的固定单元510，使其与温度探测单元100之间的距离d不能随便偏移，保证测量的准确和稳定。优选的，所述电阻检测***还包括位置调节单元（图中未示出），与所述固定单元510和/所述温度探测单元100连接，调整所述加热器500与所述温度传感器110的相对位置，特别是将加热器500与温度传感器110之前的距离d调整到温度传感器110的焦距上，使得加热器500位于温度传感器110的最佳测量位置。本发明还提供一种电阻检测方法，反应前述电阻检测***的工作过程，包括如下步骤：
S1、固定加热器与温度探测单元之间的距离，使得所述加热器位于所述温度探测单元内设置的至少一个温度传感器的检测范围内；
S2、将电能供给到加热器，使其升温，检测所述加热器的温度和电阻值；
S3、当所述加热器达到预设温度，记录在此温度下所述加热器的电阻值。

4）后续装机时，将此电阻值写入烟具的控制板，用于烟具在后续使用过程中的温控参数。后续使用过程中，只要加热器500的电阻值达到上述温控参数，即表明加热器500已经到达了需要的目标温度，即可调整供电方式，例如调整功率或者停止供电或者停止供电。
