具体实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施方式。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施方式。相反地，提供这些实施方式的目的是使对本发明的公开内容理解的更加透彻全面。
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。本文所使用的术语“内”、“外”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
图1示出了本发明一些实施例中的发热组件10，该发热组件10可用于电加热烟具或医疗器械领域使用的吸入式加热器，其包括筒状的壳体11以及设置在壳体11内的固定座14；安装在固定座14上的加热片12。
壳体11包括内层11a和外层11b，且内层11a和外层11b之间设有空隙。采用双层结构的壳体11具有很好的隔热效果，可以防止加热片12在加热过程中热量传递到壳体11外表面，从而避免烫伤。此外，壳体11上还可设有连接电池组件20的连接结构，整个壳体11可为塑料壳，采用塑胶材料制成，节约成本，使得该加热组件10可以一次性使用。
结合图2和图3，加热片12的一个表面或两个表面涂有气溶胶生成物质层15；该气溶胶生成物质层15经加热后可以产生气体、或气溶胶物质。该气溶胶生成物质层15可以为固体、膏状物、胶状物等。可以理解地，采用这 种涂布有气溶胶生成物质层15的加热片12，直接放入加热式吸入器，在加热该加热片12时，可以产生气体或者气溶胶，从而无需额外再在该壳体11内添加其他烟草制品或者药品等气溶胶生成物质，较为方便快捷，且该加热片易于清洗。另外，该加热片12结构简单、成本低，可一次性使用。可以理解地，该加热片12也可以多次使用。
如图4所示，该加热片12可用于加热烟草制品或者药品等气溶胶生成物质的吸入式加热器，该加热片12包括加热部121、电连接部122以及气溶胶生成物质层15。其中，加热部121与电连接部122相连；气溶胶生成物质层15涂布在加热部121的表面上。需要说明的是，气溶胶生成物质层15是由烟草制品或者药品等气溶胶生成物质涂布在加热部121表面上所形成的层状结构，也就是说，在一些实施方式中，可以通过烟草制品或者药品等气溶胶生成物质先形成气溶胶生成物质层15，再贴到加热部121的表面上。本实施方式，电连接部122包括正极电连接部和负极电连接部，正极电连接部和负极电连接部间隔地设置在加热部121的底部，以分别与电池组件20的正极和负极电连接。加热部121与电连接部122可以是一体结构，以简化制作工艺，且可以使电流的流向更加稳定。
加热部121呈平坦的片状，方便制造且占用空间小，空间散热均匀。加热部121包括至少一道缝隙结构13，该缝隙结构13用于引导通过加热部121的电流流向而使加热部121发热均匀。可以理解的，缝隙结构13包括至少两道缝隙结构13；该至少两道缝隙结构13包括两道或者N道缝隙结构，该N大于2，这些缝隙结构13将加热部121分隔出N+1个串联的加热单元；且这些缝隙结构13中至少有两道缝隙结构13由加热部121底边向顶边延伸；从而在加热部121的底部形成正极电连接部和负极电连接部
再如图2所示，N道缝隙结构13包括依次排布的第一缝隙结构131、第二缝隙结构132以及第三缝隙结构133，其中，第一缝隙结构131和第三缝隙结构133分别由加热部121的底边朝顶边延伸，第二缝隙结构132由加热部121的顶边向底边延伸。缝隙结构13将加热部121规划成一个规律的串联 电路，在电流通过电连接部122流入加热部121时，使得整个加热部121发热均匀，避免与电连接部122相连一端的加热部121在热传导过程中热量损失较远离电连接部122一端的加热部121快，造成加热部121整体发热不均匀。
如图5所示，第一缝隙结构131、第二缝隙结构132以及第三缝隙结构133依次将加热部121分隔成两个第一加热段和至少一个第二加热段，两个第一加热段分别位于第二加热段的两侧，并且与电连接部122相连接，其中，所述第一加热段的宽度小于第二加热段。且该第一加热段的宽度从靠近电连接部122到远离电连接部122的方向上逐渐变宽，也就是说第一加热段在靠近电连接部122到远离电连接部122的方向上电阻值随宽度的变宽而变小，即在第一加热段与电连接部122相连的地方具有较大阻值，热效率高，以此补偿经电连接部122热传导而损失的热量，进而使得第一加热段各部分发热均匀。
上述实施方式中，该第一加热段包括第一加热单元1211、以及第四加热单元1214，第一加热单元1211与正极电连接部连接，第四加热单元1214与负极电连接部连接。第二加热段包括靠近第一加热单元1211的第二加热单元段1212以及靠近第四加热单元1214的第三加热单元1213；也就是说，所述第二加热单元段1212和所述第三加热单元1213依次串联在所述第一加热单元1211和所述第四加热单元1214之间。在本实施方式中，第一加热单元1211和第四加热单元1214的宽度小于第二加热单元1212和第三加热单元1213的宽度。由于第一加热单元1211和第四加热单元1214位于加热片12的边缘，散热速度快；且由于第一加热单元1211和第四加热单元1214与电连接部122相连，热量因为热传导，损失快。因此，第一加热单元1211和第四加热单元1214被设置为窄点，可以获得有较大的功率。
具体地，第一加热单元1211与第二加热单元1212的宽度比控制在0.5-0.7之间，第四加热单元1214与第三加热单元1213的宽度比也控制在0.5-0.7之间。比如，第一加热单元1211和第四加热单元1214的宽度可设为1.15mm， 第二加热单元1212与第三加热单元1213的宽度可设为2.2mm。
在一些实施方式中，第一加热单元1211和第四加热单元1214的宽度沿着加热部121的底边到顶边的方向逐渐增大；也就是说，第一加热单元1211和第四加热单元1214越靠近加热部121的底边部分具有越大的电阻值，即热效率越高，以此补偿第一加热单元1211和第四加热单元1214靠近电连接部122的部分因热传导而损失的热量，进而使得第一加热单元1211和第四加热单元1214各部分发热均匀。具体地，可通过设置不同的第一缝隙结构131和第三缝隙结构133方式来实现。例如，第一缝隙结构131和第三缝隙结构133的宽度相同且向上延伸时渐渐地向第二加热单元1212或第三加热单元1213方向偏移一部分距离；另一种设置方式，第一缝隙结构131和第三缝隙结构133竖直向上延伸且宽度逐渐变小设置。
在一些实施方式中，第一缝隙结构131和第三缝隙结构133的宽度大于第二缝隙结构132的宽度。由于第一加热单元1211和第四加热单元1214加热时功率较大，通过第一缝隙结构131和第三缝隙结构133的宽度大于第二缝隙结构132的宽度设置，可以防止第一加热单元1211和第四加热单元1214靠近加热片121内侧的一侧温度过高，从而使得加热部121整体温度更加均匀。具体地，第一缝隙结构131和第三缝隙结构133的宽度与第二缝隙结构132的宽度比控制在1.8-2.2之间。比如，第一缝隙结构131和第三缝隙结构133的宽度取0.1mm，第二缝隙结构132的宽度取0.05mm。
具体地，在一些实施方式，第一加热单元1211和第四加热单元1214宽度取1.15mm，长度取8mm；第二加热单元1212和第三加热单元1213宽度取2.2mm，长度取8mm；第一缝隙结构131和第三缝隙结构133宽度取0.1mm，长度取5.5mm；第二缝隙结构132宽度0.05mm，长度5.5mm；水平部1221宽度取2mm，长度取2mm；垂直部1222宽度取2mm，长度取1.55mm。
结合图5，固定座14设有供加热部121插置的长条状安装孔140，该安装孔140中设有线性抵接部141，线性抵接部141从安装孔140的一个侧壁面朝相对的另一个侧壁面伸出，以抵压固定加热部121；固定座14还包括一 个中心通孔142，中心通孔142与安装孔140相交，也就是说，中心通孔142和安装孔140之间是相连通，这样，加热部121插置在安装孔140时，线性抵接部141可以将加热部121抵接固定在安装孔140内；如图5所示，线性抵接部141位于中心通孔142和安装孔140的交汇处，即中心通孔142的开设使得线性抵接部141之间形成拱形，使得线性抵接部141具有良好的张力性能，提高对加热部121的抵压固定效果。本实施方式中，固定座14可以采用耐高温、不导电材料，例如陶瓷、瓷芯、云母板等。
再结合图4，在一些实施方式中，电连接部122包括水平部1221和垂直部1222；水平部1221连接在加热部121和垂直部1222之间，且与加热部121位于同一平面上；垂直部1222垂直于水平部1221；水平部1221与壳体11的轴向平行，垂直部1222与壳体11的轴向垂直；加热部121安装在固定座14上时，水平部1221固定在线性抵接部141上，垂直部1222与固定座14底部贴合。
结合图7和图8所示，在一些实施方式中，固定座14包括基座143和压盖144，压盖144上开设有插槽1441，电连接部122的水平部1221穿过插槽1441，并将垂直部1222固定于基座143和压盖144之间，从而将加热片12的加热部121固定住。本实施方式中，由于垂直部1222被固定在基座143和压盖144之间，因此，垂直部1222处于基座143的上表面143a上，此时，在基座143的上表面143a上设置凸起1431，凸起1431的位置与垂直部1222相对，在固定加热片12时，凸起1431可以将垂直部1222抵压在压盖144上，以防止垂直部1222在基座143和压盖144之间移动，提高加热片12的安装稳定性。
结合图9至图12所示，在一些实施方式中，基座143和压盖144之间可以采用卡扣连接进行固定。具体的，基座143的上表面143a上设有卡扣1432，相应的，在压盖144上设有与该卡扣1432配合的扣槽1442。在固定加热片12时，可以将电连接部122的水平部1221穿过压盖144上的插槽1441，然后弯折该电连接部122穿过插槽1441的部分，即形成垂直部1222。将压盖 144卡扣固定在基座143上时，垂直部1222便被夹持在凸起1431和压盖144之间。需要说明的是，基座143和压盖144之间不仅可以采用上述的卡扣连接方式进行固定，还可以采用螺纹旋合等其它可拆卸连接的方式进行固定。
上述实施方式中，垂直部1222不仅可以设置在加热部121的同侧，还可以设置在加热部121的不同侧，如图9所示，垂直部1222位于加热部121的两边，即，垂直部1222错开布置在基座143上，从而增大垂直部1222之间的距离，方便在垂直部1222的下方设置电性触点来导通加热部121。当然，这样设置也会相应增加固定座14对加热片12固定的稳定性，位于不同侧的垂直部1222在凸起1431的作用下分别在抵压在压盖144上，使得加热片12两侧的受力均匀，从而避免了加热片12倾向一侧。
如图6所示，另一实施方式的加热式吸入器，包括电池组件20以及加热组件10；加热组件10与电池组件20可拆卸地连接。
电池组件20包括电池壳体21、电池22以及两个导电结构23，电池22安装在电池壳体21内，两个导电结构23分别与该电池的正极和负极电连接，同时，两个导电结构23分别与加热组件10的加热片12的正极电连接部和负极电连接部电连接；从而实现加热片12与电池22之间的电性连接。
导电结构23包括导电柱231、触头232、弹簧233。触头232安装在导电柱231内并从导电柱231的顶部露出；所述弹簧233设置在所述导电柱231上而将所述触头232抵向所述加热组件10，从而在加热组件10和电池组件20连接时，弹簧可以将触头232抵接在加热片12的电连接部122上，使得加热组件10上的电连接部122与导电结构23更充分地接触，保证电池22向加热片12供电的稳定性。
此外，电池组件20上还包括气流量调节组件，该气流量调节组件包括环状连接件，该环状连接件可以安装在电池壳体21上，且环状连接件上开设有通气孔；在环状连接件上滑动装配控制阀门，以调节通气孔大小，进而实现气流量的调节。需要说明的是，一方面，气流量调节组件可根据用户需求调节气体通入量，增加用户体验感；另一方面，由于电池组件20的结构复杂且 使用寿命远远大于加热组件10的使用寿命，也就是说，一个电池组件20往往可以搭配多个加热组件10使用，将气流量调节组件设置在电池组件20上，而没有设置在加热组件10上，从而可以避免气流量调节组件随加热组件10一起报废，进而降低使用成本。此外，本实施方式中，整个加热组件是一次性使用消耗品，因此，也不存在清洁等问题。
结合图7至9所示，在另一些实施方式中，导电结构23还包括导柱安装座210，触头232安装在导柱安装座210内，将导柱安装座210连接在电池壳体21靠近加热组件10的一端，可以理解的，触头232从导柱安装座210面向加热片12的一端露出，以在加热组件10安装在电池组件20上时，触头232可以与加热组件10的加热片12相抵接，进而实现加热片12和电池22的电性连接。可以理解的，在本实施方式中，弹簧233可以设置在触头232和导柱安装座210之间，以在加热组件10和电池组件20装配时，弹簧233可以将触头232抵向加热片12的电连接部122，以保障触头232与加热片12之间良好的电性接触，进而确保电池22有效的向加热片12的供电。
结合图13所示，上述实施方式中，加热式吸入器还包括温控电路板30，温控电路板30电性连接在加热片12与电池22之间，以采集加热片12的温度并根据采集的温度对加热片12进行温度调节控制。本实施方式中，加热片12采用电阻温度系数的材料制成，这样，加热片12的电阻值会随温度变化，相应的，可以根据加热片12的电阻值来确定加热片12的温度，具体的，温控电路板30包括电压测量模块31、电流测量模块32和控制模块33，需要说明的是，电压测量模块31和电流测量模块32分别测量加热片12的电压和电流，从而可以测得加热片12的电阻值，以确定加热片12的温度，控制模块33根据该温度对电池22的输出功率进行调节，以对加热片12的温度进行调控。比如，当加热片12的温度高于预设温度范围时，则降低电池22的输出功率，进而降低加热片12的发热效率并恢复至预设温度；当加热片12的温度低于预设温度范围时，则提高电池22的输出功率，进而提高加热片12的发热效率并恢复至预设温度。需要说明的是，预设温度是使用该加热式吸入 器时的设置温度，也就是说，根据不同的需要，可以将预设温度设置成某一个特定的温度，也可以将预设温度设置成一定的温度范围，这里不再一一赘述。
上述实施方式中，电压测量模块31可以通过感测触头220与加热片12的电连接部122并联连接，以测量加热片12两端的电压；电流测量模块可以通过触头232串联在加热片12上，以测量经过加热片12的电流，需要说明的是，在本实施方式中，电流测量模块32两端的引脚AB是串联在加热片12和电池22之间，因此经过引脚AB的电流较大，也就是说，如果在引脚AB对加热片12的电压进行测量，该测得电压值就会包括引脚AB与加热片12之间电压，即在引脚AB上测得的电压跟加热片12两端的电压会存在较大的差值，相应的，以引脚AB计算得到的加热片12阻值跟实际加热片12的阻值会偏差很大，难以准确的控制加热片12的温度。为了避免加热片12两端测量电压的误差对温度控制的影响，在本实施方式中，感测触头220抵接在电连接部122的垂直部1222上，也就是说，感测触头220是将电压测量模块31直接并联在加热片12的两端，因此，在电压测量模块31两端的引脚CD之间的几乎没有电流经过，使得电压测量模块31所测得的电压值接近加热片12两端的电压值，以此电压值所算得的加热片12的阻值也会比较准确，相应的，控制模块33可以根据电压测量模块31所测得的电压值以及电流测量模块32所测得的电流值准确的控制加热片12的温度。
在一些实施方式中，在感测触头220的下方可以设置弹性件，以将感测触头220抵压在电连接部122的垂直部1222上，实现良好的电性接触。在本实施方式中，弹性件可以是弹簧，也可以是弹性材料制成的弹性棒或弹性杆。需要说明的是，感测触头220和触头232均是通过抵接在加热片12的电连接部122来实现电接触，因此，感测触头220也可以相应的设置在导柱安装座210内并从导柱安装座210面向加热片12的一端露出，以便将加热组件10安装在电池组件20上时，导柱安装座210与加热组件10中的固定座14相配合，进而将导柱安装座210上的触头232和感测触头220同时抵接在安装在 固定座14上的加热片12上，使得装配更为简便。
需要说明的是，导柱安装座210与固定座14的配合可以采用多种形式，比如插接或卡扣等可拆卸方式，还是采用磁吸的方式将导柱安装座210吸附在固定座14上，以将触头232和感测触头220抵接在加热片12的电连接部122上。
具体的，结合图10至图12所示，在一些实施方式中，基座143具有上表面143a，基座143的下方设有中空槽腔143b，且基座143上沿基座143的轴向开设有贯孔1433；贯孔1433由中空槽腔143b的顶部贯穿上表面143a，在本实施方式中，导柱安装座210插设于中空腔槽143b内，使得触头232和感测触头220穿过贯孔1433而从基座143的上表面143a露出，以便触头232和感测触头220可以与加热片12的电连接部122相抵接，以实现电池22与加热片12的电性连接以及温控电路板30与加热片12的电性连接，需要说明的是，温控电路板30中的控制模块33连接在电池22与加热片12的电性回路上以控制电池22向加热片12的输出功率，进而实现对加热片12的稳定进行调控。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施方式中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
