毛发干燥装置多用于头发的干燥和整形，也可供其他方面的干燥、美工之用。
 技术问题
现有的毛发干燥装置包括位于手柄处的进风口，以及位于体部的出风口，当手柄内的流体流入至体部内时，由于流体的惯性作用，从手柄流出的流体会继续沿手柄的延伸方向流动，在体部产生较大的阻力，影响出风口的风量及风压。

 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明，本申请实施例中所有方向性指示（诸如上、下、左、右、前、后……）仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系、运动情况等，如果所述特定姿态发生改变时，则所述方向性指示也相应地随之改变。
另外，在本申请中涉及“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个所述特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
如图1所示，本申请一实施例提供一种毛发干燥装置，包括手柄10、体部20及导风件40，手柄10设有相连通的第一进风口11及第一流道，体部20设有出风口22及第二流道，且第二流道与第一流道连通。导风件40位于体部20内，包括管体41及导流部42。一并参考图2及图3，管体41包括相对设置的第一端面411及第二端面412，第一端面411设有流体入口414，第二端面412设有与流体入口414连通的流体出口416。流体入口414与第二流道连通，即第二流道为流体在手柄10与流体入口414之间的流通路径，流体出口416则与出风口22连通。导流部42套设于管体41，并包括朝向流体入口414的导流面421，导流面421自管体41设有流体出口416的一端沿第二端面412至第一端面411的方向延伸，并朝向第一流道。
毛发干燥装置工作时，空气从第一进风口11进入手柄10内，并通过第一流道流入第二流道内，为便于理解，图中用带箭头的线条示意出空气在毛发干燥装置内部流动的路径。可以理解地，在惯性作用下，第一流道内的流体流入第二流道内后会继续沿第一流道的延伸方向流动。由于导流面421朝向第一流道，流体流入第二流道后会与导流面421接触，并沿导流面421流动。由于导流面421沿流体出口416至流体入口414的方向延伸，与导流面421接触的流体会在导流面421的作用下向流体入口414汇聚。通过导流面421对流体的导流作用，能够减小空气阻力，以增大流体入口414处的风量及风压。
在本实施例中，主要参考图1及图4，导流面421为弧面，使得流体与导流面421接触后平缓流动至流体入口414。为便于说明，图4以参照面剖切导风件40进行说明，导流面421与参照面的交线包括第一端点及第二端点，第一端点为导流面421与第一端面411距离最小的一点，第二端点为导流面421与第二端面412距离最小的一点，且管体41的轴线与参照面平行或重合。交线在第一端点处的切线L1与管体41的轴线的夹角α为0-40°，交线在第二端点处的切线与轴线的夹角β为60-90°。
可以理解地，经导流面421导流至流体入口414处的流体与导流面421分离后会在惯性作用下继续沿切线L1方向流动，若夹角α的度数过大，会有较大部分的流体与管体41的内壁接触，从而损耗较大的能量，减小流体入口414处的风量及风压。同理，第一流道内的流体在流入第二流道内并与导流面421接触时，若夹角β的值过小，导流面421在沿第一流道的延伸方向上对流体的阻碍作用较大，会使得流体的能量有较大损失，从而减小沿导流面421流动的流体的风量及风压。若夹角β的值过大，虽然会减小从第一流道流入的流体的阻碍作用，但导流面421将流体导流至流体入口414的作用也会减弱。
此外，在本实施例中，导流面421沿第一端面411至第二端面412的方向凹陷，以将流体平缓引导至流体入口414。
需要说明的是，本实施例中的导流部42的形状不做限定，可以是螺旋绕设在管体41上，也可以是对称套设在管体41上，可以是封闭的环状，也可以是非封闭的环状。
应当注意的是，在其他实施例中，导流面421也可以为平面，以简化导风件40的结构，降低加工难度。而且，导流面421与管体41的轴线的夹角为10-45°。同理，若导流面421与管体41的轴线的夹角过小，导流面421在沿第一流道的延伸方向上对流体的阻碍作用较大。若导流面421与管体41的轴线的夹角过大，导流面421将流体导流至流体入口414的作用也会减弱。而且，在管体41的长度及导流面421与管体41设有流体出口416的一端的连接位置确定的情况下，导流面421与管体41的轴线的夹角在此范围内使得导流面421靠近流体入口414的一端距离流体入口414的距离较小，以将流体有效引导至流体入口414，保证导流面421的导流效果。
值得一提的是，在本实施例中，导流面421关于对称面对称，且手柄10的轴线及体部20的轴线均位于对称面上，如图1及图4所示，该对称面与上述剖切面共面。流体流入第二流道时，在管体41的作用下大致分为环绕管体41的两部分，导流面421为对称结构使得环绕管体41流动的两部分流体流动时更加规律，以减弱流体流动时的阻力，并减小流体流动产生的噪音。当然，在其他实施例中，导流面421也可以是不对称的，即导流面421位于参照面两侧的形状及尺寸可以有不同。
而且，在本实施例中，主要参考图1及图5，毛发干燥装置还包括风机组件60，具体地，风机组件60包括相连接的电机及风扇，电机位于管体41内，并与管体41连接，电机能够驱动风扇转动，以增加流体入口414处的吸力，增强第二流道内的流体汇聚至流体入口414处的效果，从而增加流体出口416及出风口22处的风压及风量。而且，电机设置在管体41内还可以有效利用管体41内部的空间，以减小体部20的体积。在其他实施例中，风机组件60还可以位于管体41外部，并位于流体出口416与出风口22之间，或者，风机组件60还可以位于手柄10内。
主要参考图3及图4，导风件40包括设于管体41内的第一凸起44，第一凸起44设有多个，且多个第一凸起44间隔设置。电机安装在管体41内时，电机与第一凸起44接触，相较于电机与管体41的内壁完全贴合的方案，能够减小电机与导风件40的接触面积，使得电机有一定的振动空间，以减弱电机工作时由于振动产生的噪音。而且，通过设置第一凸起44，能够增加导风件40朝向电机的表面的面积，以增加导风件40内部声波的反射及折射，从而降低电机产生的噪音。同时，第一凸起44还能够增加导风件40的结构强度。
本实施例中，一并参考图6及图7，第一凸起44沿管体41的轴线延伸，以便于通过模具成型。而且，相邻的两个第一凸起44之间的距离沿管体41的径向向内方向逐渐增大。如此，可以保证第一凸起44与管体41的内壁连接处的结构强度，并使得第一凸起44具有较大的表面积。
具体地，主要参考图6及图7，在垂直于管体41的轴线的截面上，第一凸起44的截面形状为三角形，且相邻的两个第一凸起44的顶点的距离H1为0-10mm，以保证第一凸起44的数量。而且，第一凸起44的顶点与管体41的内壁（为便于理解，图中用虚线示出管体41的内壁）的最小距离H2为0-3mm，避免第一凸起44在管体41内占用较大空间而使得体部20的尺寸增加。
应当注意的是，在本实施例中，第一凸起44的截面形状为等腰三角形，以降低加工难度。在其他实施例中，第一凸起44的截面形状也可以为直角三角形等其他形状，或者，其表面还可以是弧面，即其截面形状为拱形。而且，其截面形状还可以是矩形或倒三角形，以使得相邻的两个第一凸起44之间的距离沿管体41的径向向内方向减小或保持不变。而且，第一凸起44还可以是点状结构，或者是环绕管体41的轴线设置的环形结构。
值得一提的是，在本实施例中，管体41的外壁包括位于导流面421与第二端面412之间的背风面，导风件40包括设于背风面的第二凸起46，第二凸起46设有多个，且多个第二凸起46间隔设置。第二凸起46能够增加管体41的结构强度，并使得导风件40的外表面的面积增加，以增强导风件40的散热效果。而且，第二凸起46设置在背风面上，不会影响导风件40对流体的导流作用。
在本实施例中，导风件40一体成型，能够降低导风件40的制作难度，简化导风件40的安装步骤。在其他实施例中，管体41与导流部42也可以分开制造后再进行组装，或者，导流部42还可以与体部20一体成型。
此外，如图1所示，体部20设有与第二流道连通的第二进风口21，且第二进风口21与流体入口414相对设置。通过设置第二进风口21，能够增加毛发干燥装置整体的进风面积，以增加毛发干燥装置的风量及风压。而且，通过设置第二进风口21，还能够减小毛发干燥装置的噪音。
毛发干燥装置还包括用于供用户控制毛发干燥装置的风量及工作温度的控制部80。在本实施例中，控制部80与手柄10连接，并位于第一流道内。空气从第一进风口11进入第一流道后，能够对控制部80进行散热。而且，控制部80的长度较长，将控制部80设置在手柄10内能够有效利用手柄10内的空间，避免将控制部80设置在体部20内使得体部20的体积较大，以减小毛发干燥装置的整体体积。同时，由于控制部80位于手柄10内，体部20选用材料时不用考虑材料对控制部80的影响，使得体部20可以选用金属材料进行制造，以增加毛发干燥装置的质感，提升用户体验。
以上所揭露的仅为本申请较佳实施例而已，当然不能以此来限定本申请之权利范围，因此依本申请权利要求所作的等同变化，仍属本申请所涵盖的范围。
