 本发明的实施方式
下面结合附图所示的实施例对本申请作进一步说明。
在本申请中，应理解，诸如“包括”或“具有”等术语旨在指示本说明书中所公开的特征、数字、步骤、行为、部件、部分或其组合的存在，并且不旨在排除一个或多个其他特征、数字、步骤、行为、部件、部分或其组合存在的可能性。
另外还需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
参考图1-图3，本申请的实施例提供一种加热不燃烧装置，包括加热腔1和红外加热器2；加热腔1的底壁具有插孔1a，插孔1a位于底壁的中部区域；红外加热器2包括柱状的载体21、位于载体21外侧面上的红外涂层22、与红外涂层22电连接的电极(例如第一导体环23a、第二导体环23b和电极涂层23c)；载体21的顶面封闭，载体21的顶面以及载体21与红外涂层22相对的部分从插孔1a插入加热腔1；与红外涂层22电连接的电极引出至加热腔1外。
红外涂层22的材料例如是远红外纳米陶瓷涂层材料等。在红外涂层22的两端之间施加电压能够激发红外涂层22发射红外线。
使用时，将烟料置于加热腔1内，红外加热器2插入烟料内部，从烟料内部向周围辐射红外线，烟料对红外线的吸收更加充分且均匀，烟料的利用率更高，产生的烟雾更充足。
可选地，插孔1a位于加热腔1的底壁的中心。如此使得对烟料的加热更加均匀。
可选地，在加热腔1的内壁上设置有红外线反射结构(未示出)。红外线反射结构例如是涂覆在加热腔1内壁上的红外线反射涂层。其可以将未被烟料吸收的红外线再次反射向烟料，从而使得烟料的加热更加充分以及均匀。
可选地，参考图1和图2，载体21为中空结构且在载体21的底面形成开口24，加热不燃烧装置还包括测温元件3以及与测温元件3电连接的电极3a，测温元件3从开口24插入载体21的中空区域，与测温元件3电连接的电极引出至加热腔1外。
测温元件3插入载体21内部，有利于准确检测红外加热器2的温度。从而可以精确控制红外加热器2的温度。
如载体21的底面位于加热腔1外，与测温元件3电连接的电极3a自然也位于加热腔1外。本申请对于测温元件3电连接的电极如何设置不做限定。
可选地，测温元件3包括：热敏电阻、热电阻和热电偶中的任一项。这些测温元件3都适于放置在载体21的中空区域内。
可选地，载体21的顶面外还形成有尖端25，尖端25的指向为载体21的底面指向载体21的顶面的方向。尖端25可以是与载体21一体结构，也可以是与载体21为两个不同的部件，其作用是便于红外加热器2插入烟料中。当然，如果载体21本身直径较小，也可以不设置尖端25。
可选地，红外加热器2还包括位于红外涂层22背向载体21一侧的绝缘保护层(未示出)。绝缘保护层一方面对红外涂层22进行机械保护，另一方面需要对红外线的传导损耗较低，且耐高温。为此，绝缘保护层的材料例如是玻璃。
可选地，载体21的材料需要耐高温性、高导热性、高绝缘性且制作工艺简单。基于此，载体21的材料可以包括:石英玻璃、云母和陶瓷中的任一项。
可选地，红外加热器2还包括：环绕载体21且靠近载体21的底面的底座26。底座26的设置是为了便于红外加热器2与加热腔1之间的装配。底座26的上表面可以是与加热腔1底壁的下表面之间设置一定间距。底座26也可以直径略小，刚好卡在加热腔1底壁的插孔1a内。底座26与红外涂层22之间存有足够大的缝隙，从而保证红外涂层22完全深入烟料内部。
可选地，载体21的横截面呈圆形或多边形。红外涂层22的横截面的形状也是圆形或多边形。如此，是为了使不同方向上烟料的加热都较为均匀。
可选地，参考图1，与红外涂层22电连接的电极中位于加热腔1内的部分包括：第一导体环23a和第二导体环23b，第一导体环23a套在红外涂层22靠近载体21底面的部分外，第二导体环23b套在红外涂层22靠近载体21顶面的部分外。
第一导体环23a和第二导体环23b例如是金属环(例如铜环、钢环等)，其应与红外涂层22紧密接触，从而能够在红外涂层22的两端之间施加电压。
第一导体环23a和第二导体环23b可以各自通过附在载体21外表面上的导线引出至加热腔1，从而与加热腔1外部的控制单元4实现电连接。底座26则相应地套在该导线外。当然，将加热腔1内部的第一导体环23a和第二导体环23b引出至加热腔1外的方式不限于此(例如也可能是经穿透底座26的连接器引出至加热腔1外)。
可选地，与红外涂层22电连接的电极中位于加热腔1内的部分还包括：位于第一导体环23a和第二导体环23b之间且环绕红外涂层22的电极涂层23c，电极涂层23c与红外涂层22接触。电极涂层23c例如是金属涂层。电极涂层23c可以是一个也可以是分开的多个。如此，可以实现对烟料的不同区域分区域的加热，从而提高烟料的利用率，并能控制烟雾量。
电极涂层23c引出加热腔1的方式例如是在前述的绝缘保护层敷在电极涂层23c上，在绝缘保护层上开通孔，通过这个通孔内填充导电浆料，再由导电浆料在绝缘保护层上形成走线，该走线被底座26环绕且延伸至底座26下方，然后经电极线连接至控制单元4。当然，电极涂层23c如何与加热腔1外的结构实现电连接的方式不限于此。
可选地，参考图3，加热不燃烧装置还包括：控制单元4，与红外涂层22电连接，控制单元4用于控制红外涂层22的发热功率。
具体地，控制单元4可以包含诸如微控制单元(MCU)的控制器以及DCDC转换器等。DCDC转换器的输出电压加载在红外涂层22上。DCDC转换器受MCU的控制，将电源5提供的电压转换为合适的电压值，从而控制红外涂层22的发热功率。
可选地，当加热器包括插入载体21中空区域的测温元件3时，控制单元4还与测温元件3电连接，控制单元4还用于：根据测温元件3反馈的电信号确定红外涂层22的温度，调整红外涂层22的加热功率以使红外涂层22的温度达到预期温度。如此，可对红外涂层22的温度实现精确的控制，提高烟雾的品质。
图3中还示出了电源5和外壳6。这部分按照常规设计即可。
本申请中的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。
本申请的保护范围不限于上述的实施例，显然，本领域的技术人员可以对本申请进行各种改动和变形而不脱离本申请的范围和精神。倘若这些改动和变形属于本申请权利要求及其等同技术的范围，则本申请的意图也包含这些改动和变形在内。
