本申请实施方式提供一种干燥设备。本申请的干燥设备可以通过利用红外(IR)辐射源作为热能源以从物体(例如头发、织物)去除水和湿气。红外辐射源可以发射具有预设波长范围和功率密度的红外能量以加热物体。红外能量携带的热量以辐射传热的方式直接传递至物体，使得与传统的对流传热方式相比，传热效率得到了提高(例如，基本上没有热量以辐射传热的方式被周围的空气吸收，而传统的热传导方式一大部分的热量被周围空气吸收后被带走)。红外辐射源可以与电机结合使用，电机产生的气流进一步加速了水从物体的蒸发。
利用红外辐射作为热能源的另一个好处是，红外热量可以穿透发干直到毛外皮的皮层，因此使头发干燥得更快，并且使头发松弛和柔软。红外能量还被认为有利于头皮健康，并通过增加头皮的血流量来刺激头发生长。红外辐射源的使用还可以使干燥设备紧凑轻便。红外辐射源的提高热传递效率和能量效率还可以延长由嵌入式电池供电的无线干燥设备的运行时间。
请参图1，本申请实施方式提供的一种干燥设备100可包括壳体10、电机20和辐射源30。壳体10内设有风道40。壳体10可容纳各种电气、机械和机电组件，例如电机20、辐射源30、控制板(未示出)和电源适配器(未示出)等。
壳体10可包括本体102和把手104，本体102和把手104中的每个都可以在其中容纳电气、机械和机电部件的至少一部分。在一些实施方式中，本体102和把手104可以是一体连接的。在一些实施方式中，本体102和把手104可以是单独的部件。例如，把手104可从本体102拆卸。在一个示例中，可拆卸把手104可在其中容纳用于为干燥设备100供电的电源(如一个或多个电池)。壳体10可以由电绝缘材料制成。电绝缘材料的示例可以包括聚氯乙烯(PVC)、聚对苯二甲酸乙二醇酯(PET)、丙烯腈-丁二烯-苯乙烯共聚物(ABS)、聚酯、聚烯烃、聚苯乙烯、聚氨酯、热塑性塑料、硅树脂、玻璃、玻璃纤维、树脂、橡胶、陶瓷、尼龙和木材。壳体10也可以由涂有电绝缘材料的金属材料制成，或者由电绝缘材料与涂有或未涂有电绝缘材料的金属材料的组合制成。例如，电绝缘材料可以构成壳体10的内层，而金属材料可以构成壳体10的外层。在一个示例中，把手104上还设有输入组件106，输入组件106可用于供用户操作干燥设备，例如开关干燥设备，调节电机转速，辐射源的功率等。输入组件106可包括实体按键、虚拟按键、触摸屏中的至少一者。在其它实施方式中，干燥设备也可省略输入组件，可以通过与干燥设备通信的终端对干燥设备进行控制，终端可包括但不限于手机、平板电脑、可穿载智能设备、个人计算机等。
壳体10可以在内部设置一个或多个风道40，风道40可固定在壳体10内，以使得电机20所产生的气流能够稳定流动，避免出现期望外的气流扰动。电机20产生的气流可以被引 导或调节通过风道并朝向使用者的头发。例如，风道40可以成形为至少调节离开干燥设备100的气流的速度、通过量、发散角或涡流强度。风道40可以包括气流入口402和气流出口404。在一个示例中，气流入口402和气流出口404可以沿着干燥设备100的纵向方向(如本体102的长度方向)放置在干燥设备100的相反端处。气流入口402和气流出口404可以各自是通风口，该通风口允许有效的气流通过量。可以将环境空气通过气流入口402抽入风道40中以产生气流，并且所产生的气流可以通过气流出口404离开风道40。电机20可以位于本体102的风道40内，也可以位于把手104的风道40内，在此不作具限定。气流入口402也可设置在把手104，或把手104和本体102。
气流出口404的截面形状可以是任何形状，优选圆形、椭圆形、长方形(矩形)、正方形、或者圆形和四边形的各种变体，比如四个角圆滑处理的四边形等。在此不作具体限定。
在一个示例中，本体102内设有一个风道40，风道40基本呈圆柱状。可以理解，在其它实施方式中，风道40还可以呈其它形状，例如漏斗形状，Y形状等各种规则或不规则形状，在此不作具体限定。
在一个实施方式中，可以在气流入口402处设置一个或多个空气过滤器(图未示)，以防止灰尘或头发进入风道40。例如，空气过滤器可以是具有适当网格尺寸的网格。空气过滤器可以是可拆卸的或可更换的，以进行清洁和维护。在一个实施方式中，可以在气流出口404处设置气流调节器(图未示)。气流调节器可以是可拆卸的管嘴、梳子或卷曲器。气流调节器可以被配置为调节从气流出口404吹出的气流的速度、通过量、发散角或涡流强度。例如，气流调节器可以成形为使气流会聚(例如集中)于距气流出口404前方的预设距离处。例如，气流调节器可以被成形为使离开气流出口404的气流发散。
在一个实施方式中，由于壳体10内设在用于产生红外辐射的辐射源30，因此，壳体10中可没有额外的加热设备，一方面，可以对辐射源30的辐射功率进行调节来达到预期的干燥效果，另一方面，没有额外的加热设备还可实现干燥设备100的小型化，进而提升干燥设备100的便携性，没有额外的加热设备也可使得干燥设备100的能耗较低，这样可以增加干燥设备100的续航。在一些实施方式中，加热设备包括电热丝(如电阻丝)。
在一个实施方式中，电机20位于壳体10中并用于在风道40中产生气流。在一个示例中，电机20可以设置在本体102的风道40内并靠近气流入口402。电机20可以包括驱动部202和叶轮204。叶轮204可以包括多个扇叶。当叶轮204由驱动部202驱动时，叶轮204的旋转可以将环境空气通过气流入口402送入风道40中以产生气流，推动所产生的气流通过风道40并将气流从气流出口404排出。驱动部202可以由支架支撑或容纳在护罩中。电机20可以包括无刷电机20，可以在控制器(未示出)的控制下调节叶轮204的旋转速度。例如，可以通过预设程序、用户输入或传感器数据来控制叶轮204的旋转速度。在一些实施 方式中，在任何方向上测量的驱动部202尺寸可以均处于14mm(毫米)到21mm之间的范围中。电机20的功率输出可以处于35至80瓦(W)的范围中。从气流出口404离开的气流的最大速度可以至少为8米/秒(m/s)。
在图1和图2中示出了电机20设置在本体102中，可以理解，在其它实施方式中，电机20也可以设置在把手104中。例如，叶轮204的旋转可将空气抽入设置在把手104处的气流入口402中并将空气推动通过风道40到设置在本体102的一端处的气流出口404。风道40可以相应地延伸通过壳体10的把手104和本体102。
在一个实施方式中，电机20的扇叶通过频率接近于超声波的频率范围。扇叶通过频率可以表示为电机转速与电机20的扇叶数量的乘积。电机20的扇叶通过频率接近于超声波的频率范围，可以理解为，扇叶通过频率位于超声波的频率范围内，或扇叶通过频率是超声波的频率范围的上限或下限，或扇叶通过频率与超声波的频率范围的上限或下限之间的差值小于预设值。在一个例子中，电机20的转速单位为rps(转每秒)，扇叶通过频率大于等于15KHz。
在一个实施方式中，电机20的扇叶数量为5以上的质数。
在图1的示例中，辐射源30有一部分位于风道40外，另一部分可以和风道40进行热交换，例如辐射源30可包括反光杯302，反光杯302外壁(如迎风面)的一部分位于风道40外，该部分并没有被风道40的气流吹到，进而该部分与风道40的热交换量较小，一方面，能够对辐射源30进行适当散热，另一方面，也能够使辐射源30工作时保持在合适的工作温度，可提高物体上的水的蒸发效率。
在一个实施方式中，电机20的转速大于等于50000rpm(转每分)。也就是说，电机转速至少为每分钟5万转。如此，利用高速电机20(电机20的转速大于等于50000rpm)，在产生足够的风量的同时，也能够对辐射源30作适当的散热。
具体地，在现有技术中，由于使用低速电机，为了给单个大功率的辐射源进行有效散热，通常是将辐射源整体地直接放置在风道中，例如，辐射源的反光杯的整个外壁(即整个迎风面)直接被风道的气流吹到，来带走辐射源的热量。但这种干燥设备的缺点是1)沿风道轴向(如水平方向)的本体长度较长(尺寸大)，因为a)辐射源的反光杯一般为抛物线型，比较长；b)离辐射近的气流出口温度极高，需要设置隔离装置防止烫伤和事故。2)风道40里的辐射源的形状(如反光杯的外壁形状)会对气流有影响，比如产生风阻、风噪、改变气流的方向等，最终损耗了风的能量。
在本申请实施方式中，物体将以热传递形式在红外到可见波长范围内进行辐射。这种热传递称为黑体辐射。黑体辐射是宽带辐射。中心波长以及光谱带宽随温度升高而降低。总能量与S×T 4成比例，其中S表示表面积，T表示温度。给定辐射源30的黑体辐射需要的工 作温度和高速电机20的风量(以Cubic per Minute/CPM来衡量)，可以推导出散热效率，进而推导出辐射源30需要的散热面积。这个散热面积比现有技术将整个辐射源30放入风道40的散热面积小，所以本申请实施方式中的辐射源30一部分可位于风道40外，没有被风道40的气流直接吹到，也可以使得即使使用大功率单一辐射源30的情况下，也能够使辐射源30保持在合适的工作温度，同时，由于辐射源30的一部分位于风道40外，结构上可以将辐射源30沿风道40的径向(如竖直方向)进行偏置，可减少本体102的长度，辐射源30的形状对气流不利影响也降低了。
在一个实施方式中，电机20通过减震装置(图未示)固定在壳体10内。如此，可以减少或避免电机20所产生的震动传递到壳体10，避免对用户在使用上造成困扰。
具体地，减震装置可包括弹性件，在电机20运行时所产生的震动，可通过弹性件进行吸收，减少震动的传递。
在一个实施方式中，减震装置与辐射源30固定连接。如此，增加电机20产生的震动的传递路径，进一步减少电机20产生的传递到壳体10的震动。具体地，减震装置与辐射源30固定连接，辐射源30可固定在壳体10内，这样，形成的震动传递路径进一步为，电机20->减震装置->辐射源30->壳体10。
在一个实施方式中，减震装置包括由弹性材料形成的套筒，套筒包括围绕套筒延伸的与壳体10、风道40和辐射源30中的至少一者柔性耦合的卡接部。如此，通过柔性耦合的卡接部，减少震动传递。
具体地，套筒可以套设在电机20的驱动部202外部，卡接部可以设置在套筒的外表面，卡接部可以形成为多个(两个或多于两个)，沿套筒的周向均匀间隔设置，以均匀地减少震动传递。当然，卡接部也可形成为单个，单个卡接部呈环形设置在套筒的外表面。

具体地，通过对辐射源30出光方向的调整，来使多个辐射源30在距离风道40的气流出口一定距离形成一光斑。光斑可以是圆形光斑，圆形光斑的直径可以为10cm。在一个例子中，一定距离可以是10cm。光斑还可以是椭圆形光斑，或其它形状的光斑，在此不作具体限定。可以理解，光斑的数量还可是两个或多个两个，通过对辐射源30的开口方向调整来实现。例如，辐射源30的数量是6个，可以是6个辐射源30可形成一光斑，也可以是3个辐射源30形成一光斑，另3个辐射源30形成另一光斑等。较佳地，光斑的数量小于辐射源30的数量。

在本申请实施方式中，对应一定的辐射照度，照到目标物体(被干燥物体)上的光斑有最优面积(同时热辐射的作用面积与风的作用面积有耦合关系，应尽量匹配，由此可确定发一个最优的辐射照射面积，如，直径10cm的圆内)，由此可推算出最终作用在目标物体上的辐照通量最优值(辐射照度x照射面积)，再通过辐射源30辐射到指定区域内的辐射能量/电能转换效率算出各种辐射源30布置方案所需的电功率，进而可选择合适的辐射源30的发光件的个数和尺寸组合和相应反光杯302的尺寸。在这些组合中，如果使用单个辐射源30，由于红外光射出后会发散，故辐射源30开口(反光杯302开口)处的热辐射功率密度较高，可能短时间内造成灼伤，而多个辐射源30可分开设置(多个辐射源30的总功率和单个辐射源30的功率相同)，每个辐射源30的开口(辐射出射口)的热辐射功率密度相对更低，更安全。

反光杯302可以被配置为调节从发光件304发射的辐射方向。例如，反光杯302可以被配置为减小反射的辐射束的发散角。
反光杯302的反射面可以涂有对由发光件304发射的辐射的波长或波长范围具有高反射率的涂层材料。例如，涂层材料可以对可见光谱和红外光谱两者中的波长都具有高反射率。 具有高反射率的材料在反射辐射能的方面可以具有很高的效率。涂层材料的示例可以包括金属材料和介电材料。金属材料可以包括例如银和铝。介电涂层可以具有交替的介电材料层，例如氟化镁。设有涂层的反射面的反射率可以为至少90％(例如90％的入射辐射被反光杯302的反射表面反射)、90.5％、91％、91.5％、92％、92.5％、93％、93.5％、94％、94.5％、95％、95.5％、96％、96.5％、97％、97.5％、98％、98.5％、99％、99.5％、99.6％、99.7％、99.8％、99.9％或更高。在一些实例中，设有涂层的反射面的反射率可以为大致为100％，这意味着可以将由发光件304发射的基本所有辐射都朝着干燥设备100的外部进行反射。因此，即使发光件304的温度高，反光杯302的反射面上的温度也基本上不会由于从发光件304发射的辐射而升高。
在一个实施方式中，反光杯302的反射面的轴向截面为多项式曲线的形状。如此，可以使反射面形成有焦点，便于对红外辐射的导向及减少反射的辐射束的发散角。
具体地，多项式曲线的形状，可包括抛物线、椭圆、双曲线等形状。在一个示例中，反光杯302的反射面的轴向截面为抛物线的形状。
在一个实施方式中，发光件304设置于反光杯302的反射面的焦点处。如此，可以使得发光件304发出的红外光束经反射面反射后，基本上平行地从反光杯302的开口出射，使得干燥设备100的发出的红外辐射的指向性好。
具体地，发光件304设置于反光杯302的反射面的焦点处，在焦点处的发光件304发射的红外辐射束经反光杯302的反射面反射后，基本相互平行地由反光杯302的开口出射。
在其它实施方式中，发光件304也可以偏离抛物线的焦点放置，使得反射的红外辐射束可以在干燥设备100前方的一定距离处会聚或发散。发光件304在反光杯302中的位置是可以调节，因此，可以改变输出的辐射束的会聚程度和/或方向。反光杯302的形状和发光件304的形状可以相对于彼此优化和变化，以在干燥设备100的期望位置输出期望的加热功率。
另外，可以在发光件304和反光杯302之间插入绝热材料(例如，玻璃纤维、矿棉、纤维素、聚氨酯泡沫或聚苯乙烯)，使得发光件304与反光杯302绝热。即使发光件304的温度高，热绝缘也可以保持反光杯302的温度不增加。也可以在光学元件的周边和反光杯302之间插入绝热材料，使得光学元件与反光杯302绝热。
在一个实施方式中，请参图19，辐射源30包括第一反光件306，第一反光件306设置在发光件304内。如此，可以将发光件304内的红外辐射反射至反光杯302的开口处，提升了红外辐射的利用率。
具体地，第一反光件306的反光面的轴向截面可为多项式曲线的形状，例如为抛物线形状。第一反光件306可采用耐高温材料，反光面上设置镀膜，该镀膜是对红外辐射具有高反射率。在一个示例中，发光件304为灯泡。
在一个实施方式中，发光件304包括夹封位308，第一反光件306靠近夹封位308设置。如此，可以将从夹封位308漏出的红外辐射反射至反光杯302的开口。
具体地，发光件304可包括灯丝，灯丝连接夹封位308。灯丝通电时发出红外辐射，红外辐射向四周发射，部分红外辐射会射向夹封位308。因此，在靠近夹封位308的位置设置第一反光件306，可以利用第一反光件306将该部分的红外辐射反射至反光杯302的开口，进而提升了红外辐射的利用率。第一反光件306与夹封位308的距离可以预先进行标定，在此不作具体限定。在一个示例中，第一反光件306可安装在灯丝靠近夹封位308的位置。
在一个实施方式中，发光件304包括发光部309，第一反光件306的反光面的轴向横截面为面向发光部309的多项式曲线的形状，发光部309位于第一反光件306的反光面的焦点处。如此，可以使得由发光部309向第一反光件306发射的红外辐射经第一反光件306反射后，形成平行光束向反光杯302的开口出射。
具体地，多项式曲线的形状，可包括抛物线、椭圆、双曲线等形状。在一个示例中，第一反光件306的反光面的轴向截面为抛物线的形状。
发光部309是通电时发出红外辐射的部位。在一个示例中，发光部309可为灯丝(如钨丝)。可以理解，在其它示例中，发光部309还可呈块状，或其它形状。
在一个实施方式中，发光件304包括发光部309，发光部309由导电支架支撑，第一反光件306安装在导电支架，辐射源30包括绝缘件，绝缘件连接导电支架和第一反光件306。如此，可以使得导电支架和第一反光件306之间绝缘。
具体地，发光件304还包括位于夹封位308处的引脚，导电支架可连接引脚和发光部309，第一反光件的材质可为金属，第一反光件306安装在导电支架上，和导电支架连接的地方要绝缘，以在安装时防短路。因此，绝缘件可以连接导电支架和第一反光件306，使得导电支架和第一反光件306之间绝缘，保证了发光件304的正常工作。
在一个实施方式中，发光件304包括夹封位308，第一反光件306由绝缘支架支撑，绝缘支架连接夹封位308。如此，可以实现第一反光件306的安装。
具体地，第一反光件306可不安装在发光部309上，可以由另外的绝缘支架安装在夹封位308。
在一个实施方式中，辐射源30包括第二反光件312，第二反光件312位于发光件304内靠近发光件304的顶部。如此，可以提升红外辐射的利用率。
通常地，发光部309发出的且经反光杯302开口边缘出射的光线的发射角度较大，这部分光线直接出射的话可能无法照射到目标物体上。通过在发光件304上方安装第二发光件304，位于反光杯302焦点处的发光部309发出的该部分光线可以被第二反光件312反射回反光杯302内，由反光杯302再重新反射，进而减少该部分光线的发射角度，使该部分光线 能够被导向目标物体。
在一个实施方式中，第二反光件312的反光面的轴向横截面为面向发光件304的多项式曲线的形状，发光件304位于第二反光件312的反光面的焦点处。如此，可以使得由发光部309向第二反光件312发射的红外辐射经第二反光件312反射后，形成平行光束向反光杯302内出射。
具体地，多项式曲线的形状，可包括抛物线、椭圆、双曲线等形状。在一个示例中，第二反光件312的反光面的轴向截面为抛物线的形状。
在一个实施方式中，第二反光件312开设有通光孔(图未示)。如此，可以使发光部309发出的部分光线由通光孔出射。
具体地，在一个实施方式中，第二反光件312的平面形状可为圆形，通光孔可以开设在圆心附近，这样，与通光孔相对的发光部309发光的光线可以直接从通光孔出射，这部分光线的发射角度通常是较小，因此，可以允许这部分光线直接从通光孔出射，而不经第二反光件312的反射。
在一个实施方式中，发光件304包括发光部309，发光部309由导电支架支撑，第二反光件312安装在导电支架，辐射源30包括绝缘件(图未示)，绝缘件连接导电支架和第二反光件312。如此，可以使得导电支架和第二反光件312之间绝缘。
具体地，第二反光件312的材质可为金属，第二反光件312安装在导电支架上，和导电支架连接的地方要绝缘，以在安装时防短路。因此，绝缘件可以连接导电支架和第二反光件312，使得导电支架和第二反光件312之间绝缘，保证了发光件304的正常工作。
在一个实施方式中，发光件304包括夹封位308，第二反光件312由第二绝缘支架支撑，第二绝缘支架连接夹封位308。如此，可以实现第二反光件312的安装。
具体地，第二反光件312可不安装在发光部309上，第二反光件312可以由位于夹封位308的另外的绝缘支架支撑，并靠近发光部309的顶部。
在一个实施方式中，请参图20和图22，反光杯302的壁形成有避空部，避空部的形状与风道40和/或壳体10相适应。可以使得干燥设备100更紧凑。
具体地，在多个辐射源30中，反光杯302的构型(抛物线型)会占用设备空间和/或压缩风道40(进而对风产生影响)。由于干燥设备100整体的尺寸限制，可以通过提高辐射源30的数量，同时减小单个反光杯302的尺寸来提高整体的空间利用率。但由于各种辐射源30工艺的限制(如灯泡中灯丝尺寸)的限制，如果反光杯302与辐射源30的尺寸相对过小，辐射效率会严重衰减。同时由于将发光件304安装在反光杯302里，反光杯302内需要一些安装定位结构，而此部分结构对小反光杯302的反射杯型的破坏比大尺寸反光杯302更大。而在给定的产品外形里，用大的反光杯302可能会超出外形限制，在满足辐射效率和以 上两个约束下，需要对反光杯302进行外观避空切割以与风道40和/或壳体10相适应。
辐射源30通过反光杯302壁与风道40进行热交换。传统反光杯302的构型使反光杯302壁和风道40的接触面积有限。要提高面积，需要部分反光杯302壁去侵蚀风道40，从而影响风速、风量和产生风阻。所以需要切割侵入风道40的反光杯302壁以适应风道40的形状，这样可以降低对风的影响。这样的好处在于，在给定壳体10尺寸的情况下，风道40的口径会比传统的大。
同时，反光杯302与壳体10内壁接触的部分也通过切割来适应那部分的形状。请结合图22，通过仿真对比不切割的反光杯发现，对于一定口径的反光杯302，上述两部分的切割对反光杯302的出口总功率和一定距离外的光斑的能量密度影响不明显，在可接受的范围内。
具体地，避空部可以是反光杯302外壁因适应风道40和/或壳体10的形状而形成的部位。这样，在反光杯302与风道40和/或壳体10耦合时，在不影响风道40和/或壳体10外形的情况下，可以减少装配后的整体尺寸。
需要说明的是，避空部的设置需要考虑因素如下：
切割面积：和散热效率和维持发光件304工作温度有关；
切割面的形状(与风道40接触面的切割)：平衡对风的影响和光的反射路径(进而影响光的汇聚)；
切割位置：对于不同的切割位置，出口功率和目标光斑处的功率存在最优解。
在切割时，需要注意：
入切口：在多项式曲线(如抛物线)的焦点的平面前方。
出切口：要满足干燥设备100的本体的外壁以及风道40的构型限制。
在图20-图21中，多个辐射源30围绕风道40的气流出口404布置。
在图23-图24中，多个辐射源30布置在风道40的气流出口404的一侧，在图示中是上半侧。
在图25-图26，图27-图28中，多个辐射源30被风道40包围。
在一个实施方式中，避空部包括第一避空部314，第一避空部314的形状与风道40的轮廓匹配。如此，可以使得反光杯302能够更靠近风道40设置，提升了干燥设备100的空间利用率。
在一个实施方式中，第一避空部314上距离反光杯302的开口最远的点位于反光杯302的反射面的焦点的靠近反光杯302开口的一侧。如此，可以保证避空部的入切口在反光杯302的焦点的平面前方。
具体地，反光杯302的反射面的轴向截面为多项式曲线(如抛物线)的形状。第一避空 部314上距离反光杯302的开口最远的点在入切口处。这样，可以使得发光件304发出的光线能够被连接避空部的反射面部位反射形成平行光束出射，减少避空部对发光件304发出光线的影响。
在一个实施方式中，第一避空部314与风道40内的气流接触。如此，可以提升第一避空部314与风道40的热交换效率。
具体地，第一避空部314可以形成为风道40的壁一部分，这样第一避空部314可与风道40内的气流接触，而被气流带走热量。
在一个实施方式中，风道40的轮廓为圆形，以壳体10径向截面的中心为圆心。第一避空部314的形状可以呈圆弧形，弧度与风道40的轮廓相适应，第一避空部314能够与风道40较好地贴合。一方面，提升热交换效率，另一方向，结构也更紧凑。
可以理解，在其它实施方式中，部分风道40的轮廓还可以是圆环的内或外轮廓的凹形，以壳体10径向截面的中心为圆心。
在一个实施方式中，避空部包括第二避空部316，第二避空部316的曲率不同于第一避空部314的曲率。如此，可以使反光杯302能够适应干燥设备100的其实部件。
具体地，第二避空部316位于相对于第一避空部314远离风道40的一侧。第二避空部316可与壳体10的内壁形状匹配，进一步减少反光杯302的空间占用，提升空间利用率。
具体地，在一个示例中，第二避空部316可与本体的内壁形状匹配。可以理解，第二避空部316还可以与干燥设备100的其它部件的形状匹配，在此不作具体限定。
在一个实施方式中，相邻两个辐射源30的两个反光杯302连接形成有共用部317。如此，能够进一步减少多个辐射源30的空间占用，提升了壳体10内的空间利用率。
具体地，在相邻两个辐射源30中，两个反光杯302通过共用部317连接，共用部317可以是反光杯302的壁。共用部317可以呈平板状以进一步减少两个反光杯302所占用的空间。
在一个实施方式中，反光杯302的反射面的径向和轴向截面为至少一个多项式曲线形状的一部分。具体地，多项式曲线形状包括圆、抛物线、椭圆、双曲线等形状。在一个示例中，反光杯302的反射面的轴向截面为至少一个抛物线形状的一部分，反光杯302的反射面的径向截面为至少一个抛物线形状的一部分。
在一个实施方式中，反光杯302的反射面的不同径向截面为不同心的圆形。可以理解，在其它实施方式中，反光杯302反射面的不同径向截面也可以是不同心的椭圆。
在一个实施方式中，反光杯302的反射面的径向和轴向截面由分段的多项式曲线连接而成。
在一个实施方式中，请参图29及图30，反光杯302包括基座310，发光件304连接基 座310，基座310不位于反光杯302外壁的顶点，发光件304位于反光杯302的焦点处。如此，可以实现发光件304的非正装安装方式。
非正装安装方式的好处是：1)夹封位308的热可以直接被传导，以和风道或风道内的空气进行热交换，或者直接辐射出去；2)因为基座处的夹封位比较长，想要保证发光件在反光杯的焦点处，正装的情况下往往使基座很长，占空间。非正装(如侧装和倒装)可以节省空间。
具体地，反光杯302的反射面(反光杯302的内壁)的轴向截面可为多项式曲线形状，反光杯302的外壁的轴向截面也呈这种形状，在这种形状下，反光杯302外壁具有一顶点。在本申请的一个实施方式中，请参图31，基座位于反光杯外壁的顶点，这种属于正装的方式。
在本申请实施方式中，发光件304位于反光杯302的焦点处，即发光件304位于反光杯302的反射面的焦点处。
基座310不位于反光杯302外壁的顶点，在一个实施方式中，请参图29，基座310位于反光杯302的侧壁。如此，可实现发光件304的侧装安装方式。
在一个实施方式中，反光杯302的侧壁与风道40壁耦合。如此，可以使得发光件304的热量可通过基座310，反光杯302的侧壁与风道40壁进行热交换，能够对发光件304进行适当散热。
具体地，风道40壁的热量能够被风道40内的气流带走，进而可对发光件304散热。
辐射源30可围绕风道40的气流出口布置，反光杯302的侧壁与风道40壁耦合，可以是反光杯302的壁与风道40壁直接接触，也可以通过额外的散热结构连接，还可以是反光杯302的壁形成风道40壁的一部分，具体请参本申请相关的实施方式，在此不作具体限定。
在一个实施方式中，反光杯302的侧壁用于与风道40中的气流进行热交换。如此，可以使得发光件304的热量可通过基座310，反光杯302的侧壁与风道40中的气流进行热交换，能够对发光件304进行适当散热。
具体地，辐射源30可被风道40包围，这样，反光杯302的侧壁会被风道40中的气流吹到，进而带走发光件304的热量，具体请参本申请相关的实施方式，在此不作具体限定。
基座310不位于反光杯302外壁的顶点，在一个实施方式中，请参图30，发光件304位于反光杯302的开口处。如此，可实现发光件304的倒装安装方式。

在一个实施方式中，反光杯302的开口处的壁上有凹槽，凹槽容纳发光件304的灯脚或者连接发光件304的灯脚的导线。具体地，可以将发光件304的灯脚或者连接发光件304的 灯脚的导线通过连接件318引到凹槽中。
在一个实施方式中，基座310开设有开孔，开孔容纳发光件304的灯脚或者连接发光件304的灯脚的导线。如此，发光件304的灯脚或连接发光件304灯脚的导线能够穿过基座310，并可穿过连接件318与外部电源连接。
在一个实施方式中，开孔由绝缘、绝热以及不透光的材料封闭。如此，可以减少红外辐射的泄露。
在一个实施方式中，请结合图32A-图32B，辐射源30包括光学元件90，光学元件90设置在反光杯302的开口处，用于滤除或反射非红外波段的辐射。如此，可以使得只有红外辐射导向至被干燥的物体。
具体地，光学元件90可以包括改变或重新引导光的透镜、反射器、棱镜、光栅、分束器、滤光器或它们的组合。在一些实施例中，光学元件90可以是透镜。在一些实施例中，光学元件90可以是菲涅耳透镜。
在一个实施方式中，非红外波段的辐射包括可见光和/或紫外光。光学元件90可以由具有高红外透射率的材料制成。用于光学元件90的材料的示例可以包括氧化物(例如二氧化硅)、金属氟化物(例如氟化钡)、金属硫化物或金属硒化物(例如硫化锌、硒化锌)和晶体(例如晶体硅，晶体锗)。进一步地，光学元件90的任一侧或两侧可以涂有吸收或反射可见光谱和紫外光谱的材料，使得仅红外范围内的波长可以穿过光学元件90。光学元件90可以滤出(例如吸收)不在红外光谱中的辐射。光学元件90的红外透射率可以为至少95％(例如，红外光谱中95％的入射辐射透过光学元件90)、95.5％、96.0％、96.5％、97.0％、97.5％、98.0％、98.5％、99％、99.1％、99.2％、99.3％、99.4％、99.5％、99.6％、99.7％、99.8％、99.9％或更高。在一个示例中，光学元件90的红外透射率可以是99％。
在一个示例中，发光件304可以发射波长为0.4μm到20μm的辐射，反光杯302可以将所有辐射朝向光学元件90反射(例如，没有辐射在反射表面处被吸收)，并且光学元件90可以从反射的辐射中滤出处于0.4μm至0.7μm之间的任何可见光谱波长，从而使得仅红外光谱中的辐射离开辐射源30。
在一个实施方式中，光学元件与反光杯的热膨胀系数差值在预设范围内。如此，使得光学元件和反光杯的热膨胀系数相近，避免因热膨胀系数相差较大而在受热时使热膨胀系数小的部件变形。热膨胀系数可以根据产品性能，通过仿真或测试来选择，在此不作具体限定。
在一个实施方式中，光学元件90密封反光杯302的开口。如此，可以使反光杯302内形成相对密封的内部空间。

在一个实施方式中，反光杯302内填充有保护气体，保护气体可以是一定量的非氧化性气体(如惰性气体)，同时仍保持一定水平的真空以减少由反光杯302和光学元件90的内表面形成的空间内部的气体的温度的升高。该温度升高虽然很小，但是由热对流和热传导引起的。非氧化性气体的例子可以包括氮气(N2)、氦气(He)、氩气(Ar)、氖气(Ne)、氪气(Kr)、氙气(Xe)、氡气(Rn)和氮气(N2)。惰性气体的存在可以进一步保护发光件304的材料免受氧化和蒸发。
在图32A所示的实施方式中，多个辐射源30共用同一个光学元件90，也就是说，一个光学元件设在所有辐射源的反光杯302的开口处。在图32B所示的实施方式中，每个辐射源具有一个光学元件90，也就是说，一个光学元件90设在一个反光杯302的开口处。在其它实施方式中，部分辐射源共用同一个光学元件，其余部分辐射源中的每个辐射源具有一个光学元件。

具体地，控制板可以将电源70的电压转换为适应于干燥设备100工作模式所对应的辐射源30的电压，和电机20的电压，使得辐射源30和电机20能够在该工作模式下工作。例如，通过对电压的调整，可以调整辐射源30的辐射功率，电机20的转速(即扇叶的转速)等。或对电源70进行通断，来控制辐射源30和电机20的工作时长。可以理解，在其它实施方式中，电源70、控制板、辐射源30和电机20还可以是其它连接方式。在一个示例中，电源70可以安装在把手104中。
在一个实施方式中，电源70包括可充电电池。如此，可以使干燥设备100使用时可脱离线束的束缚，提升用户体验。

在一个实施方式中，干燥设备100还包括传感器，传感器感测干燥设备100、干燥设备100所处的工作环境、气流或辐射的接受体中的至少一者的状态。如此，可以根据传感器的信号来控制干燥设备100运行，提升用户体验。
具体地，状态包括温度、湿度、距离、姿态、运动、流量、通量中的至少一者。
传感器可以包括温度传感器、接近/测距传感器、湿度传感器、姿态传感器、流量传感器、通量传感器中的至少一者。传感器可以例如放置在壳体10的气流出口404侧，以监视被干燥物体(即气流或辐射的接受体)状态(例如湿度)。气流施加到被干燥物体上的区域可以大致包括被干燥物体上的红外辐射区域(例如，辐射斑点)。气流可以通过吹走被干燥物体周围的湿空气来加速水从被干燥物体蒸发。气流还可以降低由红外辐射辐射的被干燥物体的温度，以避免被干燥物体受损。被干燥物体和被干燥物体上的水的温度必须保持在适当的范围内，以加速水从被干燥物体的蒸发，同时保持被干燥物体不要过热。适当的温度范围可以是50到60摄氏度。可以调节吹到被干燥物体上的气流的速度，以例如通过吹走热水和多余的热量来将被干燥物体的温度保持在适当的温度范围内。接近/测距传感器和温度传感器可以共同运行以确定被干燥物体的温度并通过反馈回路控制来调节气流的速度，以保持被干燥物体的恒定温度或编程温度。被干燥物体例如可为头发。
姿态传感器可以采集干燥设备100姿态和运动。例如姿态传感器可包括惯性检测模块(IMU)，可以检测干燥设备100的横滚轴、俯仰轴及偏航轴中至少一者的状态，也可以检测在相应轴上是否处于运动。例如，当用户长时间对着被干燥物体的一个部位吹时，姿态传感器检测到干燥设备100是长时间没有运动，那么，为避免对被干燥物体的该部位造成损伤，控制板可以根据姿态传感器输出的数据，来控制电机20的转速减少和/或辐射源30的辐射强度降低，还可以控制干燥设备100进行声光、震动提示等。
流量传感器可以检测气流的流量，使得控制板可以控制电机20的转速来适应被干燥物体的温度控制。类似地，控制板也可根据通量传感器输出的通量数据来控制电机20和/或辐射源30运行。
在一个实施方式中，传感器设置在壳体10内且位于风道40的气流出口404和/或辐射源30的开口。如此，可以实现气流状态和/或辐射状态的更准确控制。
具体地，传感器位于风道40的气流出口404，可以使得对离开干燥设备100的气流状 态，如流量、通量、温度、湿度等进行检测，可以对离开干燥设备100的气流状态进行更准确控制，避免干燥设备100的内部环境影响气流状态的检测。类似地，传感器位于辐射源30的开口，可以使得对离开干燥设备100的辐射状态，如强度等进行检测，可以对离开干燥设备100的辐射状态进行更准确控制，避免干燥设备100的内部环境影响辐射状态的检测。
综上，上述实施方式的干燥设备100，包括但不限于以下技术效果：
1.相对于传统的干燥设备100(如反光杯302外壁的全部直接在风道40中)太过散热，会影响辐射效率，因为过量的散热意味着发光件304需要将额外的电能转化为热能以维持产生黑体辐射所必要的温度。本申请实施方式的干燥设备100的构型可以适当降低辐射源30的温度，延长发光件304的使用寿命，同时又不至于把温度降得太低造成电能浪费(更多电能要用来维持黑体辐射的温度)。
2.辐射源30多余的热量被风带走，让风温上升几度(1～5度)，虽然完全不足以对干发产生决定性影响，但提升了风吹到人体后人的体感，让人不会感到被冷风吹，提升了用户体验。
在本说明书的描述中，参考术语“一个实施方式”、“一些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合实施方式或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一者实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
尽管已经示出和描述了本申请的实施方式，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施方式进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
