本申请实施例采用递进的方式撰写。
如图1所示，本申请实施例提供一种加热烟具，包括：烟支容纳腔1和形成烟支容纳腔1的壳体2，以及设置在壳体2上加热单元、控制单元和采集单元，其中：
烟支容纳腔1的内环下部缩径设置，以形成用于限定烟支位置的限位台阶4；限位台阶4上存在与烟支容纳腔1中插入的烟支5的底部端面接触的第一端面6，第一端面6上预设有第一通孔7；
采集单元包括第一红外温度传感器8，第一红外温度传感器8，布置在第一通孔7的正下方；第一通孔7在第一红外温度传感器8所在的水平面形成的第一投影区域9，与第一通孔7之间，形成半封闭的第一通道10；第一红外温度传感器8，用于通过第一通道10，测量第一通孔7区域的温度；
加热单元的位置，高于限位台阶4的位置，加热单元用于对烟支容纳腔1中的烟支5进行加热；
控制单元，与加热单元和采集单元连接；控制单元，用于获取烟支容纳腔1中的烟支5的目标加热温度和采集单元测量的实时温度；控制单元，还用于将实时温度和目标加热温度进行比较，并根据比较结果，对加热单元进行控制，以使采集单元测量的实时温度等于目标加热温度。
在具体实施例中，烟支容纳腔1的高度可以根据实际应用需求进行设定。烟支容纳腔1的内径，可以略大于烟支5直径，以便烟支5顺利插入并且不会晃动。具体地，当烟支5插入烟支容纳腔1后，烟支5的底部端面可以与限位台阶4上的第一端面6抵接。第一端面6上预设有第一通孔7，第一通孔7与布置在第一通孔7正下方的第一红外温度传感器8所在的水平面之间，可以对应形成第一投影区域9，第一投影区域9与第一通孔7之间，形成半封闭的第一通道10，也就是说，第一通道10的底部是封闭式的，即为第一投影区域9，第一通道10的顶部为非封闭式的，即为第一 通孔7。第一红外温度传感器8，可以布置在第一投影区9，第一红外温度传感器8，用于通过第一通道10，对第一通孔7区域进行红外温度测量。其中，第一通孔7的大小及形状，可以实际应用需求设置。
在具体实施例中，采集单元中的第一红外温度传感器8与第一通孔7的距离，可以根据实际需求确定。当烟支5插入烟支容纳腔1时，烟支5的底部端面与限位台阶4的第一端面6接触，加热单元的位置高于限位台阶4的位置，加热单元用于对烟支5的烟丝段11进行加热，第一红外温度传感器8通过第一通道10测量第一通孔7区域的温度，即烟支5的底部端面的温度，可以直接测量反映烟丝温度。基于上述设置，能够使作为测温元件的第一红外温度传感器8，在远离加热区域的情况下，实现烟支5的底部端面的温度的测量，能够提高测温的准确性。
在具体实施例中，加热单元可以包括对称设置的极板3，通过极板3输出高频电磁波，以对烟支进行加热，极板3可以镶嵌在烟支容纳腔1的壳体2的壳壁内。在另一些实施例中，加热单元可以包括磁感应线圈，通过磁感应线圈输出高频电磁波，磁感应线圈绕设在烟支容纳腔1的壳体2的外表面上或镶嵌在烟支容纳腔1的壳体2的壳壁内，磁感应线圈的绕制方向与烟支容纳腔1的壳体2轴向平行。在另一些实施例中，加热单元，可以包括发热体(如金属发热体或陶瓷介质发热体)，通过发热体与烟丝接触，来对烟丝进行加热；加热单元还可以合理采用其他类型的加热组件，本申请不限于此。
在具体实施例中，控制单元，可以通过设置在加热烟具上的输入组件获取目标加热温度，目标加热温度也可以根据烟支类型预先设置，本申请对此不作限制。在一些实施例中，控制单元，将采集单元测量的实时温度和目标加热温度进行比较，当实时温度低于目标加热温度时，可以控制加热单元加大输出功率；当实时温度高于目标加热温度时，可以控制加热单元减小输出功率；当实时温度和目标加热温度相等时，可以不执行操作，加热单元维持当前的输出功率。控制单元，基于目标加热温度和实时温度，对加热单元进行控制，可以实现加热烟具的精准控温。控制单元还可以合理采用其他控制方式，本申请不限于此。
现有加热卷烟器的测温方式，一般是将测温元件直接布置在卷烟加热器的加热区域进行测温，测温元件处于加热区域中，测温元件自身温度升高，也会影响加热卷烟器测温及控温准确性。
上述实施例，涉及一种加热烟具，当烟支5插入加热烟具的烟支容纳腔1时，烟支5的底部端面与限位台阶4的第一端面6接触，加热单元的位置高于限位台阶4的位置，加热单元用于对烟支容纳腔1中的烟支5进行加热，第一端面6上预设有第一通孔7，采集单元包括布置在第一通孔7的正下方的第一红外温度传感器8，第一红外温度传感器8通过与第一通孔7之间的第一通道10，测量第一通孔7区域的温度，即烟支5的底部端面的温度，可以直接测量反映烟丝温度。基于上述设置，能够使作为测温元件的第一红外温度传感器8，在远离加热区域的情况下，实现烟支5温度的测量，可以提高测温的准确性；同时，通过控制单元，获取烟支5的目标加热温度和采集单元测量的实时温度，并根据两者的比较结果，对加热单元进行控制，以使采集单元测量的实时温度等于目标加热温度，以此可以实现加热烟具的精准控温。综上所述，上述实施例能够提高加热烟具测温和控温的准确性。
特别地，当加热单元采用高频加热方式时，基于上述设置，能够使作为测温元件的第一红外温度传感器8，在远离高频电磁场区域的情况下，实现烟支5温度的测量，一方面可以减小高频电磁场对测温元件的电学性质的影响，另一方面可以避免测温元件在高频电磁场的作用下自身产热从而影响测温的准确性。由此可知，通过上述设置，可以减少高频电磁场对测温元件的影响，提高测温的准确性。
在本申请的其他实施例中，第一投影区域9与第一通孔7之间的距离设置为第一预设距离，以使第一端面6形成预设直径的聚焦成像点12。其中，第一预设距离，也即第一红外传感器8与第一通孔7之间的距离，聚集成像点12的直径大小随第一投影区域9与第一通孔7之间的距离的变化而改变，第一预设距离和预设直径可以根据实际应用需求设置，预设直径应设置为尽可能小的值，其目的是使布置在第一投影区域9的第一红外温度传感器8接近或达到最佳测温距离，以提高测温的准确性。在具体实施 例中，烟支5插入烟支容纳腔1后，烟支5的底部端面与第一端面6接触，当第一端面6(也即烟支5的底部端面)形成聚焦成像点12的直径最小时，第一红外温度传感器8达到最佳测温距离，即可将加热烟具第一投影区域9和第一通孔7之间的当前的距离，作为第一预设距离。
在本申请的其他实施例中，第一红外温度传感器8设置在在聚焦成像点12的正下方。相应地，第一红外温度传感器8，可以测量第一通孔7区域中心的温度，即烟支5的底部端面中心的温度，烟支5的底部端面中心的温度，更能表征烟支5的实际加热情况，以此可以提高测温的准确性。
如图2所示，在本申请的其他实施例中，采集单元还包括至少一个第二红外温度传感器13，其中：第二红外温度传感器13，布置在第一通孔7的正下方，与第一温度传感器8处于同一水平面，且在以第一温度传感器8为圆心的圆周上；第二红外温度传感器13，用于通过第一通道10，测量第一通孔7区域的温度。在本实施例中，采集单元包括至少两个红外温度传感器，通过多点测量的方式，采集单元通过多个红外温度传感器，可以同时测量第一通孔7区域的多个位置的实时温度，更能表征烟支的实际加热情况，以此可以提高测温的准确性。相应地，控制单元，可以根据目标加热温度和采集单元测量的多个实时温度进行比较来对加热单元进行控制，以此可以提高控温的准确性。
在本申请的其他实施例中，当第二红外温度传感器13为多个时，多个第二红外温度传感器13，在以第一温度传感器8为圆心的圆周上均匀布置。在本实施例中，第二红外温度传感器13通过均匀布置，可以同时测量第一通孔7区域内多个均匀分布位置的实时温度，更能表征烟支的实际加热情况，以此可以提高测温的准确性。在具体实施例中，第二红外温度传感器13的数量，可以根据实际应用需求确定，本申请对此不作限制。
在本申请的其他实施例中，当采集单元包括多个红外温度传感器时，控制单元，还用于对采集单元测量的多个实时温度进行计算处理，得到统计温度，其中：统计温度，包括多个实时温度的平均数、众数、中位数、极差、方差、标准差中的任意一种；

在本实施例中，采集单元可以包括至少两个红外温度传感器，采集单元可以同时测量第一通孔7区域的多个位置的实时温度，得到多个实时温度。通过控制单元，可以对采集单元测量的多个实时温度进行统计学计算，得到统计温度。统计温度，更能更能表征烟支的实际加热情况。同时，通过对统计温度和目标加热温度进行比较，并根据比较结果，对加热单元进行控制，以使控制单元计算得到的统计温度等于目标加热温度，以此可以提高控温的准确性。
在本申请的其他实施例中，控制单元，在执行获取烟支容纳腔1中的烟支5的目标加热温度时，具体用于：获取烟支容纳腔1中的烟支5的加热温升曲线；
相应地，控制单元，在执行对实时温度和目标加热温度进行比较，并根据比较结果，对加热单元进行控制，以使采集单元测量的实时温度等于目标加热温度时，具体用于：对实时温度和加热温升曲线的预设温度值进行比较，并根据比较结果，对加热单元进行控制，以使采集单元测量的实时温度等于加热温升曲线的预设温度值。
