参照图1，基体1具有相对的第一端11和第二端12，基体1沿第一端11和第二端12之间的轴向延伸并且内部中空形成有收容烟草基质的加热腔室13，基体1可以由石英玻璃、陶瓷或云母等耐高温且透明的材料制成，基体1优选中空的圆柱状，加热腔室13即为贯穿基体1中部的孔，只需将烟支等烟草基质***加热腔室13内即可对其进行加热。
参照图1，导电模块2包括设置在基体1上的第一导电部21和第二导电部22，其中，优选的，第一导电部21设于基体1靠近第一端11的外侧面，第二导电部22设于基体1靠近第二端12的外侧面，当然，当远红外涂层3设于基体1的内侧面时，导电模块2也可以设置在基体1的内侧面；在本实施例中，第一导电部21和第二导电部22均呈圆环状，第一导电部21和第二导电部22可以为涂覆在基体1靠近第一端11和第二端12位置的外侧面的圆环形导电涂层，导电涂层为金属涂层或导电胶带等，也可以是套接在基体1靠近第一端11和第二端12位置的外侧面的圆环形导电片，导电片为金属导电片，例如铜片、钢片等等。

参照图1，在本实施例中，第一导电部21包括第一本部211和自第一本部211沿基体轴向方向延伸的第一延伸段212，第二导电部22包括第二本部221沿基体1轴向方向延伸的第二延伸段222，第一延伸段212和第二延伸段222呈中心对称的间隔设于基体1外侧面；具体的，位于第一延伸段212与第二延伸段222之间的远红外涂层3沿基体1外侧面的周向宽度和位于第一延伸段212与第二本部221之间的的远红外涂层的轴向宽度之间的比例，和/或位于第一延伸段212与第二延伸段222之间的远红外涂层3沿基体1外侧面的周向宽度和第二延伸段222与第一本部211之间的远红外涂层3的轴向宽度之间的比例均为N，其中0.8≤N≤1.2。需要指出的是，如图1所示，上述周向宽度是指由第一延伸段212沿基体1的弧形侧面的周向方向到第二延伸段222的距离，即图1所示的距离d；上述轴向宽度是指第一延伸段212沿基体1轴向方向到第二本部221的距离，或者是第二延伸段222沿基体1轴向方向到第一本部211的距离，即图1中的距离h。在该实施例中，N优选为1，即位于第一延伸段212与第二延伸段222之间的远红外涂层3沿基体1外侧面的周向宽度与位于第一延伸段212与第二本部221之间的远红外涂层3的轴向宽度相等，和/或位于第一延伸段212与第二延伸段222之间的远红外涂层3沿基体1外侧面的周向宽度和第二延伸段222与第一本部211之间的远红外涂层3的轴向宽度相等。另外值得一提的是，在该实施例中，第一延伸段212的长度与第二延伸段222的长度相等，使得第一延伸段212与第二本部221的距离和第二延伸段222与第一本部211的距离相同。
第一延伸段212和第二延伸段222将基体1外侧面的远红外涂层3大致分为对称的两部分，第一延伸段212和第二延伸段222呈中心对称设于基体1外侧面，这样第一延伸段212顺时针沿基体1外侧面周向与第二延伸段222间的远红外涂层3的周向宽度，以及第一延伸段212逆时针沿基体1外侧面周向与第二延伸段222间的远红外涂层3的周向宽度是相等的，通过控制第一延伸段212和第二延伸段222分别与第一本部211和第二本部221之间的距离，即可控制位于第一延伸段212与第二本部221之间的远红外涂层3的轴向宽度以及第二延伸段222与第一本部211之间的远红外涂层3的轴向宽度，进而控制周向宽度与轴向宽度之间的比例，使得该比例在固定范围之内。具体的说，当第一导电部21和第二导电部22与外部电源的正负极连接后，第一导电部21与第二导电部22之间的远红外涂层3相当于一等效电阻，由于第一导电部21和第二导电部22分别具有第一延伸段212和第二延伸段222，这样，位于第一延伸段212与第二延伸段222之间的两部分远红外涂层3和位于第一延伸段212与 第二本部221之间的远红外涂层3、以及位于第二延伸段222与第一本部211之间的远红外涂层3即相当于四个并联的等效电阻，通过控制上述的周向宽度和轴向宽度之间的比例，使得这四个等效电阻的阻止大致相同，这样流过这四个等效电阻的电流大小也大致相同，即流过各部分的远红外涂层3的电流大小基本相同，远红外涂层3的各区域均有电流流过，且电流大小相差不大，各区域的远红外涂层3一起发出强度大致相同的远红外光，这样就可以对基体1内的烟草基质进行均匀辐射加热，烟支等烟草基质均匀受热，利用率高，可以有效节省成本。
进一步的，在上述实施例中，第一本部211和第二本部221可以是导电涂层，也可以是导电片，第一本部211和第二本部221为导电片时，均为具有断裂缺口的环形导电片，这样便于套入基体外侧面；第一延伸段212和第二延伸段222可以是导电片，也可以是导电涂层。当第一导电部21和第二导电部22均为导电涂层时，先在基体1外侧面涂覆远红外涂层3，然后再在远红外涂层3上涂印导电涂层，以使导电涂层与远红外涂层3紧密连接保持导电连接，保证通电顺畅。
在一实施例中，基体1的截面为圆环形，远红外涂层3附设于基体1的外侧面，第一延伸段212与第二延伸段222平行延伸且沿基体1的中心轴线对称地设置在基体1的外侧面上；这样将第一延伸段212与第二延伸段222之间的远红外涂层3分为沿基体1的周向宽度相等的两部分，远红外涂层3通电时，流过这两部分远红外涂层3的电流相同，可以发出强度相同的红外光，对基体1内的烟草基质进行均匀辐射加热。值得一提的是，在本实施例中，在第一本部211延伸至第二本部221的远红外涂层3具有均匀的厚度，以保证远红外涂层3通电后发出强度基本相同的远红外光。
参照图2-3，在一实施例中，第一导电部21还包括自第一本部211沿基体1轴向方向延伸的第三延伸段213，第二导电部22还包括自第二本部221沿基体1轴向方向延伸的第四延伸段223，第一延伸段212、第二延伸段222、第三延伸段213以及第四延伸段223呈顺时针等间隔地沿基体1的周向方向设置于基体1外侧面，且第三延伸段213的长度等于第一延伸段212的长度，第四延伸段223的长度等于第二延伸段222的长度。在该实施例中，第一延伸段212与第二延伸段222的长度相等。第一延伸段212、第二延伸段222、第三延伸段213以及第四延伸段223将基体1外侧面的远红外涂层3分为四个部分，且相邻的延伸段之间沿基体1外侧面周向的距离相同；具体的，位于第三延伸段213与第四延伸段223之间的远红外涂层3沿基体1的周向宽度与第三延伸段213与第二本部221之间的远红外涂层3的轴向宽度之间的比例、以及位于第三延伸段213与第四延伸段223之间的远红外涂层3沿基体1外侧面的周向宽度和第四延伸段223与第一本部211之间的远红外涂层3的轴向宽度之间的比例均为N1，其中0.8≤N1≤1.2，优选N1为1，也即位于第三延伸段213与第四延伸段223之间的远红外涂层3沿基体1外侧面的周向宽度与位于第三延伸段213与第二本部221之间的远红外涂层3的轴向宽度相等，和/或位于第三延伸段213与第四延伸段223之间的远红外涂层3沿基体1外侧面的周向宽度和位于第四延伸段223与第一本部211之间的远红外涂层 3的轴向宽度之间的比例相等。当第一导电部21和第二导电部22与外部电源的正负极连通时，电流从第一导电部21先流到第一延伸段212和第三延伸段213，然后一部分电流由第一延伸段212和第三延伸段213沿基体1外侧面的周向方向经远红外涂层3流向第二延伸段222和第四延伸段223，然后经第二延伸段222和第四延伸段223流到第二导电部22，另一部分电流经第一延伸段212、第三延伸段213与第二导电部22之间的远红外涂层3流向第二导电部22，最后流到外部电源的负极以形成电流回路，基体1外侧面的远红外涂层3均有电流经过，而且电流大小基本相等，远红外涂层3发出的红外光可以对基体1的加热腔室13内的烟草基质进行均匀辐射加热，烟草基质均匀受热，利用率更高，可以减少更换烟草基质的频率，进而降低使用成本。
参照图4，在一实施例中，导电模块2还包括第三导电部23，第三导电部23设于第一导电部21和第二导电部22之间的基体1外侧面，第三导电部23与远红外涂层3导电连接，第三导电部23将远红外涂层3沿基体1轴向方向分隔为两个加热区域，以实现对加热腔室13内的烟草基质的分段加热。在该实施例中，第三导电部23将远红外涂层3分割为两个加热区域，可以通过控制第一导电部21、第二导电部22以及第三导电部23的通断电实现对加热腔室13内的烟草基质的分段加热。
进一步的，第三导电部23包括第三本部231和自第三本部231沿基体1轴向方向延伸的第五延伸段232和第六延伸段233，其中第五延伸段232自第三导电部23向第一导电部21方向延伸，第六延伸段233自第三导电部23向第二导电部22方向延伸，第五延伸段232和第六延伸段233分别与第一延伸段212和第二延伸段222呈中心对称的间隔设于基体1外侧面。具体的，第三导电部23也可以具有多个延伸段，具体的分布方式与上述实施例类似，在此不再赘述。
具体的，在一实施例中，位于第五延伸段232与第一延伸段212之间的远红外涂层3沿基体1外侧面的周向宽度和位于第一延伸段212与第三本部231之间的远红外涂层3的轴向宽度之间的比例，和/或位于第五延伸段232与第一延伸段212之间的远红外涂层3沿基体1外侧面的周向宽度和位于第五延伸段232与第一本部211之间的远红外涂层3的轴向宽度之间的比例为N2，0.8≤N2≤1.2。需要指出的是，如图3所示，上述周向宽度是指由第一延伸段212沿基体1的弧形侧面的周向方向到第五延伸段232的距离，即图3所示的距离d’；上述轴向宽度是指第一延伸段212沿基体1轴向方向到第三本部231的距离，或者是第五延伸段232沿基体1轴向方向到第一本部211的距离，即图3中的距离h’。优选的，N2等于1，也即位于第五延伸段232与第一延伸段212之间的远红外涂层3沿基体1外侧面的周向宽度和位于第一延伸段212与第三本部231之间的远红外涂层3的轴向宽度相等，和/或位于第五延伸段232与第一延伸段212之间的远红外涂层3沿基体1外侧面的周向宽度和位于第五延伸段232与第一本部211之间的远红外涂层3的轴向宽度相等；以使远红外涂层3均匀发射红外光对烟草基质进行均匀加热。
进一步的，位于第六延伸段233与第二延伸段222之间的远红外涂层3沿基体1外侧面 的周向宽度和位于第六延伸段233与第二本部221之间的远红外涂层3的轴向宽度之间的比例，和/或位于第六延伸段233与第二延伸段222之间的远红外涂层3沿基体1外侧面的周向宽度和位于第二延伸段222与第三本部231之间的远红外涂层3的轴向宽度之间的比例为N3，0.8≤N3≤1.2。需要指出的是，如图3所示，上述周向宽度是指由第二延伸段222沿基体1的弧形侧面的周向方向到第六延伸段233的距离，即图3所示的距离d’；上述轴向宽度是指第二延伸段222沿基体1轴向方向到第三本部231的距离，或者是第六延伸段233沿基体1轴向方向到第二本部221的距离，即图3中的距离h’。优选的，N3等于1，即位于第六延伸段233与第二延伸段222之间的远红外涂层3沿基体1外侧面的周向宽度和位于第六延伸段233与第二本部221之间的远红外涂层3的轴向宽度相等，和/或位于第六延伸段233与第二延伸段222之间的远红外涂层3沿基体1外侧面的周向宽度和位于第二延伸段222与第三本部231之间的远红外涂层3的轴向宽度相等。
值得一提的是，在其它一些实施例中，导电部可以为多个，例如四个、五个等等，多个导电部将远红外涂层3分成三个部分、四个部分等等，以实现对烟草基质的三段、四段等段数进行加热。
参照图5-7，本申请实施例还提出一种低温加热烟具100，包括壳体组件4和上述的加热器10，加热器10设于壳体组件4内。本申请实施例的低温加热烟具100，在基体1外侧面设置远红外涂层3以及与远红外涂层3导电连接的第一导电部21和第二导电部22，并且从第一导电部21和第二导电部22分别沿基体1的轴向方向延伸的第一延伸段212和第二延伸段222，通过控制位于第一延伸段212与第二延伸段222之间的远红外涂层3沿基体1外侧面的周向宽度与位于第一延伸段212与第二导电部22之间的远红外涂层3的轴向宽度之间的比例，和/或位于第一延伸段212与第二延伸段222之间的远红外涂层3沿基体1外侧面的周向宽度与位于第二延伸段222与第一导电部21之间的远红外涂层3的轴向宽度之间的比例，使该比例在预设的范围之内，当第一导电部21和第二导电部22与外部电源的正负极连接后，电流就会从第一导电部21流向第一延伸段212，之后一部分电流沿基体1的外侧面周向方向经远红外涂层3流向第二延伸段222，另一部分电流会从位于第一延伸部与第二本部221之间远红外涂层3流到第二本部221上，当比例在预定范围内时，可以使流经基体1外侧面的远红外涂层3的电流大小基本相同，基体1外侧面上的远红外涂层3基本都有电流经过，远红外涂层3即可发出红外光对基体1的加热腔室13内的烟支进行辐射加热，烟支均匀受热，烟支的利用率高，低温加热烟具100的用户体验更好。
参照图6-7，壳体组件4包括外壳41、固定壳42、固定件43以及底盖44，固定壳42、固定件43均固定于外壳41内，其中固定件43用于固定加热器10，固定件43设置于固定壳42内，底盖44设于外壳41一端且盖设外壳41；具体的，固定件43包括上固定座431和下固定座432，上固定座431和下固定座432均设于固定壳42内，加热器10的第一端11和第二端12分别固定在上固定座431和下固定座432上，底盖44上凸设有进气管441，下固定座432背离上固定座431的一端与进气管441连接，上固定座431、加热器10、下固定座432 以及进气管441同轴设置，且加热器10与上固定座431、下固定座432之间密封，下固定座432与进气管441也密封，进气管441与外界空气连通以便于用户抽吸时可以顺畅进气。
参照图6-7，上述低温加热烟具100还包括隔热管5，隔热管5设置在固定壳42内，隔热管5套设在基体1外，隔热管5可以吸收大部分烟草基质受红外光辐射产生的热量，避免大量的热量传递到外壳41上而导致用户觉得烫手。具体的，隔热管5内还涂覆有红外光反射涂层，以将基体1上的远红外涂层3发出的红外光反射回基体1内部来加热位于加热腔室13内的烟草基质，提高加热效率。
参照图6-7，上述低温加热烟具100还包括控制主板6、按键7以及电池8，固定壳42包括前壳421与后壳422，前壳421与后壳422固定连接，控制主板6和电池8均设置在固定壳42内，电池8与主板电连接，红外发热管与主板也电连接，按键7凸设在外壳41上，通过按压按键7，可以实现对基体1外侧面上的远红外涂层3的通电或断电。在本实施例中，控制主板6还连接有一充电接口61，充电接口61裸露于底盖44上，用户可以通过充电接口61对低温加热烟具100进行充电或升级，以保证低温加热烟具100的持续使用。
进一步地，在本实施例中，低温加热烟具100还包括测温件9，测温件9设置在基体1上，测温件9为温度传感器，用于检测基体1的实时温度，并将检测的实时温度传输到控制主板6，控制主板6根据该实时温度调节流经远红外涂层3上的电流的大小。具体的，当测温件9检测到基体1内的实时温度较低时，譬如测温件9检测到基体1内侧的温度不到150℃时，控制主板6控制电池8输出较高的电压给导电模块2，进而提高远红外涂层3中馈入的电流，提高烟草基质的加热功率，减少用户抽吸第一口烟所要等待的时间；当测温件9检测到基体1的温度为150℃-200℃时，控制主板6控制电池8输出正常的电压给导电模块2；当测温件9检测到基体1的温度在200℃-250℃时，控制主板6控制电池8输出较低的电压给导电模块2；当测温件9检测到基体1内侧的温度在250℃及以上时，控制主板6控制电池8停止输出电压给导电模块2。
