 本发明的实施方式
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。
如图1及图2所示，一实施例中的毛发干燥装置10包括手柄100、体部200及导流件300。手柄100上设有第一流体入口110。体部200包括壳体210和管体220。壳体210与手柄100连接。管体220穿设于壳体210内。管体220和壳体210之间设有第一流体出口230。第一流体入口110和第一流体出口230连通形成用于供流体流动的第一流体通道120。导流件300为中空结构。导流件300可拆卸地设于壳体210上。当导流件300安装在壳体210上时，导流件300的内部与第一流体出口230相连通，以使第一流体出口230输出的流体通过导流件300并沿导流件300的引流方向流出至外部。
上述毛发干燥装置10，由于导流件300与体部200的壳体210可拆卸连接，当导流件300出现损坏需要进行维护时，可将导流件300从体部200的壳体210上拆离，以便于及时对导流件300进行维修或更换，避免将导流件300和体部200的壳体210进行整体更换，大大提升了导流件300的维护便捷性，同时降低了维护成本。
如图3所示，在一实施例中，导流件300与壳体210卡扣连接。具体的，壳体210的内侧壁上设有扣柱212，导流件300上对应设有卡槽310，扣柱212与卡槽310相卡合，以使导流件300与壳体210固定连接。
在一实施例中，导流件300的截面呈锥形状。导流件300的直径从导流件300朝向第一流体出口230的一端至导流件300背离第一流体出口230的一端的方向递减。具体的，导流件300的引流方向与壳体210的侧壁的延伸方向形成夹角。在一实施例中，夹角可以但不限于为40度。
如图2所示，在一实施例中，第一流体通道120是非线性的。第一流体通道120包括相连通的第一段122和第二段124。第一段122的延伸方向与第二段124的延伸方向垂直。第一段122位于手柄100内，第二段124位于壳体210和管体220之间。即流体沿第一流体通道120的第一段122流动穿过手柄100并沿第一流体通道120的第二段124流动穿过体部200。
在一实施例中，毛发干燥装置10还包括风扇组件400。风扇组件400设于第一流体通道120内。在本实施例中，风扇组件400位于第一流体通道120的第一段122内。风扇组件400用于抽吸流体穿过第一流体入口110进入第一流体通道120。
如图2所示，在一实施例中，管体220背离第一流体出口230的一端设有第二流体入口221。管体220朝向第一流体出口230的一端设有第二流体出口222。第二流体入口221和第二流体出口222连通形成用于供另一股流体流动的第二流体通道223。
在风扇组件400运行时，风扇组件400抽吸流体，使其穿过第一流体入口110进入第一流体通道120并到达第一流体出口230，流动穿过体部200且从第一流体出口230流出的流体的作用使得另一股流体在第二流体入口221处被卷吸或拉入到第二流体通道223内，且沿着第二流体通道223朝向第二流体出口222流动。该经由第二流体出口222流出的另一股流体与经由第一流体出口230流出的流体在导流件300的出口端汇合，从而使得毛发干燥装置10的流体的出流量增强。
具体地，第二流体通道223由管体220限定。第二流体通道223在管体220内从第二流体入口221延伸到第二流体出口222。第一流体通道120的第二段124由管体220和壳体210之间的间隙限定。第一流体出口230的截面呈环形状。第一流体出口230围绕第二流体通道223延伸。
如图2所示，在一实施例中，手柄100包括内壳130和底壳140。内壳130与壳体210连接。内壳130与壳体210的内部相互连通。底壳140设于内壳130远离壳体210的一端。第一流体通道120的第一段122由内壳130限定。第一流体通道120的第一段122在内壳130内从第一流体入口110延伸到内壳130与壳体210的连接处。第一流体入口110设于底壳140的外侧壁上。具体在本实施例中，第一流体入口110包括多个通孔112。多个通孔112间隔围设于底壳140的外侧壁上。在一实施例中，手柄100还包括外壳150。外壳150套设于内壳130上，外壳150的两端分别与壳体210和底壳140相抵接。
如图3所示，在一实施例中，毛发干燥装置10还包括端盖500。端盖500设于管体220背离第一流体出口230的一端，且与管体220背离第一流体出口230的一端之间设有第一间隙510，第一间隙510构成第二流体入口221。通过在管体220背离第一流体出口230的一端设置端盖500，且端盖500与管体220背离第一流体出口230的一端之间设有第一间隙510，不仅可以保证第二流体通道223通过第一间隙510进行另一股流体的正常流入，而且还可以对第二流体入口221进行部分封堵，以减小第二流体入口221的开口尺寸大小，防止使用过程中操作人员的手指从第二流体入口221伸入至第二流体通道223内，进而保障操作人员的人身安全。
在一实施例中，端盖500设于管体220朝向第一流体出口230的一端，且与管体220朝向第一流体出口230的一端之间设有第二间隙520。第二间隙520构成第二流体出口222，以保证第二流体通道223通过第二间隙520进行另一股流体的正常流出并对第二流体出口222进行部分封堵。
在一实施例中，端盖500设于管体220背离第一流体出口230的一端和管体220朝向第一流体出口230的一端，且分别与管体220背离第一流体出口230的一端和管体220朝向第一流体出口230的一端之间设有第一间隙510和第二间隙520。第一间隙510构成第二流体入口221，第二间隙520构成第二流体出口222，以保证第二流体通道223分别通过第一间隙510和第二间隙520进行另一股流体的正常流入和流出并对第二流体入口221和第二流体出口222同时进行部分封堵。
如图3所示，在一实施例中，端盖500包括第一端盖530。第一端盖530设于管体220背离第一流体出口230的一端。第一端盖530与管体220背离第一流体出口230的一端之间设有第一间隙510。
如图4所示，进一步地，第一端盖530包括盖体532和多个凸起534。盖体532设于管体220背离第一流体出口230的一端。多个凸起534间隔设置于盖体532的外周。任意相邻两个凸起534之间形成隔孔536。多个隔孔536共同构成第一间隙510。通过将用于构成第二流体入口221的第一间隙510分割成为多个相互独立的隔孔536，从而可以进一步减小第二流体入口221的开口尺寸大小，防止使用过程中操作人员的手指从第二流体入口221伸入至第二流体通道223内，进而保障操作人员的人身安全。
如图3所示，在一实施例中，端盖500还包括第二端盖540。第二端盖540设于管体220朝向第一流体出口230的一端。第二端盖540与管体220朝向第一流体出口230的一端之间设有第二间隙520。在一实施例中，第二端盖540依次嵌设于导流件300及管体220朝向第一流体出口230的一端内。
进一步地，第二端盖540的尺寸大小与管体220朝向第一流体出口230的一端的尺寸大小相适配，从而可以在保证对第二流体出口222部分封堵的前提下一定程度地减小第一端盖530的体积，使得管体220内部的空间更大，避免对管体220内部的其他元件造成干涉。
在一实施例中，第二端盖540通过连接部550与导流件300固定连接。进一步地，在本实施例中，第二端盖540、连接部550及导流件300一体成型。
如图3所示，在一实施例中，管体220包括依次连接的第一部分224、第二部分225及第三部分226。第二流体入口221设于第三部分226远离第二部分225的一端。第二流体出口222设于第一部分224远离第二部分225的一端。具体的，第一端盖530与第一部分224之间设有用于构成第二流体入口221的第一间隙510。第二端盖540与第二部分225之间设有用于构成第二流体出口222的第二间隙520。进一步地，具体在本实施例中，第二部分225为筒状结构。第三部分226绕第二部分225延伸。第三部分226与第二部分225之间设有第一流体出口230。
此外，第二端盖540与导流件300之间设有汇流出口310。汇流出口310与第一流体出口230和第二流体出口222均相连通。第一流体出口230输出的流体与第二流体出口222输出的另一股流体在汇流出口310汇合并沿导流件300的引流方向流出至外部。
需要指出的是，在一实施例中，第一部分224的一端与第二部分225可拆卸连接，第一部分224的另一端与壳体210可拆卸连接，以便于管体220的拆卸与维护。具体在本实施例中，第一部分224的一端与第二部分225卡扣连接，第一部分224的另一端与壳体210卡扣连接。进一步地，导流件300与第三部分226可拆卸连接，以提升导流件300相对体部200的安装稳定性。具体在本实施例中，导流件300与第三部分226卡扣连接。
如图2所示，在一实施例中，毛发干燥装置10还包括加热器600。加热器600设于第一流体通道120内。具体在本实施例中，加热器600位于第一流体通道120的第二段124内。加热器600绕管体220延伸。加热器600用于加热第一流体通道120中的流体。
在本实施例中，为便于描述，定义加热器600靠近第一流体出口230的一端为加热器600的下游端，加热器600远离第一流体出口230的一端为加热器600的上游端。流体经由第一流体入口110进入第一流体通道120且从加热器600的上游端流动穿过加热器600的下游端，然后继续沿第一流体通道120流动并到达第一流体出口230，从而实现加热器600对该第一流体通道120内的流体的可选择性地直接加热。此外，流过第二流体通道223的另一股流体也可通过该加热器600进行间接地加热。
如图5所示，在一实施例中，加热器600包括里层610和加热元件620。里层610为环形结构。加热元件620用于加热通过加热元件620的流体。在一实施例中，里层610由塑料材质制成。塑料材质为聚苯酯、聚苯并咪唑、聚硼二苯基硅氧烷、聚苯硫醚、氯化聚醚中的任意一种。塑料材质相比云母材质而言具有更好地可塑性，且硬度更高，通过将加热器600的里层610设置为由塑料材质制成，从而便于将作为该加热元件620的热绝缘支撑结构的里层610设置为其他形状以及相对固定，进而便于其他结构部件相对作为该加热元件620的热绝缘支撑结构的里层610的安装，大大提高了加热器600的承载适应性。
加热元件620设于里层610上。具体的，加热元件620用于在通电时产生热能以加热通过加热元件620的流体。加热元件620为单层。加热元件620卷绕于里层610上。通过将加热元件620设置为单层，从而可以减小加热器600的整体体积，使得流体通过加热器600的障碍更小，降低了流体通过该加热器600的流量损失，另一方面，由于流体通过加热器600的空间更小，使得流体的流速更快，大大提升了加热器600的使用性能，具有结构简单、占用空间小的特点。
如图5所示，在一实施例中，上述加热器600还包括用于隔离加热元件620的外层630。外层630为环形结构，外层630绕加热元件620延伸。加热元件620位于里层610和外层630之间。外层630可以为加热器600及容纳加热器600的结构提供热绝缘，此外，外层630还可以对加热元件620沿里层610的径向移动起到一定的限位作用。在本实施例中，外层630由绝缘材质制成，优选地，外层630由云母制成。
如图6所示，在一实施例中，上述加热器600还包括用于支撑加热元件620的支撑件640。支撑件640设于里层610上，并沿里层610的径向朝向外层630延伸。在本实施例中，支撑件640由绝缘材质制成，优选地，支撑件640由云母制成。
进一步地，支撑件640包括多个。多个支撑件640沿里层610的周向间隔排布，以提升对加热元件620的支撑稳定性。在一实施例中，支撑件640包括至少六个，至少六个支撑件640沿里层610的周向间隔排布。进一步地，支撑件640上设有用于定位加热元件620的定位口642。定位口642为锯齿形。加热元件620定位于支撑件640的定位口642内。
如图6所示，在一实施例中，毛发干燥装置10还可包括温度检测器700。温度检测器700设于第一流体通道120内。温度检测器700可以但不限于为热敏电阻。温度检测器700用于检测第一流体通道120内的流体的温度。在加热器600所在第一流体通道120的第一流体入口110或第一流体出口230发生堵塞时，由于在加热元件620上的流体的流动被限制，导致该流体无法将加热元件620上的热量及时带走，从而使得加热元件620可能会过热，温度检测器700可以及时检测第一流体通道120内的流体的温度，用户可根据温度检测器700的检测结果判断加热元件620是否出现过热，从而准确控制加热器600对第一流体通道120内的流体的加热，确保毛发干燥装置10的正常使用。
进一步地，在本实施例中，温度检测器700设于加热器600的下游端。温度检测器700用于检测加热器600和第一流体出口230之间的流体的温度。由于加热器600和第一流体出口230之间的流体的温度更加贴近毛发干燥装置10的实际出流风温，通过将温度检测器700相对加热器600的下游端的设置，使得温度检测器700能够以该加热器600和第一流体出口230之间的流体的温度作为其温度检测的参考标准，从而准确控制加热器600对第一流体通道120内的流体的加热。
如图6所示，在一实施例中，毛发干燥装置10还可包括第一过温保护件720。第一过温保护件720设于第一流体通道120内，并与加热元件620电连接。第一过温保护件720可以但不限于为金属弹片。第一过温保护件720用于在第一流体通道120内的流体的温度达到第一预设阀值时切断接入到加热元件620的电力，以及用于在第一流体通道120内的流体的温度低于第一预设阀值时导通接入到加热元件620的电力。
第一过温保护件720在通常使用中不受流动经过的流体的影响，然而在第一流体通道120的第一流体入口110或第一流体出口230发生堵塞时，第一流体通道120内的流体的温度会升高，当第一流体通道120内的流体的温度达到第一预设阀值时，第一过温保护件720将会切断接入到加热元件620的电力；当第一流体通道120内的流体的温度低于第一预设阀值时，第一过温保护件720将会重新导通接入到加热元件620的电力，从而有效地控制加热器600对第一流体通道120内的流体的加热，确保毛发干燥装置10的使用安全性能。
在本实施例中，第一过温保护件720设于里层610和加热元件620之间。由于加热元件620内部的流体的温度相对更加均匀，通过将第一过温保护件720相对加热元件620内部的设置，使得第一过温保护件720能够以该加热元件620内部的流体的温度作为其控制切断或导通接入到加热元件620的电力的温度标准，从而准确控制加热器600对第一流体通道120内的流体的加热。
如图6所示，在一实施例中，毛发干燥装置10还可包括第二过温保护件740。第二过温保护件740设于第一流体通道120内，并与加热元件620电连接。第二过温保护件740可以但不限于为热熔丝。第二过温保护件740用于在第一流体通道120内的流体的温度达到第二预设阀值时断开并切断接入到加热元件620的电力。
进一步地，第二预设阀值高于第一预设阀值。第二过温保护件740在第一过温保护件720失效的情况下工作，当第一流体通道120内的流体的温度达到第二预设阀值时，第二过温保护件740将会切断接入到加热元件620的电力，从而更加有效地控制加热器600对第一流体通道120内的流体的加热，确保毛发干燥装置10的使用安全性能。
如图2所示，在一实施例中，上述毛发干燥装置10还可包括控制器800。控制器800设于第二流体通道223内。控制器800与风扇组件400和加热器600电连接。控制器800可用于控制加热器600的加热温度以及风扇组件400的旋转速度。进一步地，控制器800与温度检测器700电连接。控制器800可用于根据温度检测器700的检测结果控制加热器600的加热温度。
如图2所示，进一步地，在一实施例中，毛发干燥装置10还包括过滤器900。过滤器900设于底壳140内，并与内壳130相连接，以防止夹杂在流体内的大颗粒尘土通过第一流体入口110进入到第一流体通道120内。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例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。
