下面结合附图和实施例，对本实用新型的具体实施方式作进一步详细描述。以下实施例用于说明本实用新型，但不用来限制本实用新型的范围。
参阅图1-图9，本实用新型提供一种低温直发装置，包括：本体1，本体1上设置有风道101、加热单元3、吸风单元和吹风单元，加热单元3用于对风道101内的空气进行加热，风道101连通有吹风口102和吸风口组103，吹风单元用于带动风道101内加热后的空气从吹风口102吹出以对头发进行加热，吸风单元用于将头发周围的空气从吸风口组103吸入风道101内以降温；吹风口102用于吹出热风对头发进行加热，吸风口组103用于将加热后头发周围的空气吸入风道101内，以对头发进行降温定型，避免头发持续处于高温状态下受到损伤，使用安全可靠，且易于造型。
参阅图2和图5，风道101内设置有风扇2，加热单元3置于风道101内，风扇2具有吹风面和吸风面，吹风面构成吹风单元，吸风面构成吸风单元；风扇2转动从而带动风道101内的空气流动；在风扇2的作用下，外界的空气从吸风口组103处进入风道101，风道101内的空气经加热单元3加热后从吹风口102处吹出，以对流的方式传递热量给头发，避免高温的发热部位直接接触头发造成损伤。
参阅图2，吸风口组103沿拉直头发的方向设置于吹风口102的后端，拉直头发的方向为从发根向发尾拉直的方向，直发时先将头发靠近发根的部位放置于吹风口102处加热，再将本体1沿拉直头发的方向移动，使得先前加热过的头发置于吸风口组103处吸风降温。
参阅图1、图2和图5，加热单元3置于吹风口102与风扇2之间，风扇2朝加热单元3一侧吹风；便于风扇2将加热单元3加热后的空气从吹风口102吹出；风扇2包括扇叶201以及与扇叶连接的高速无刷电机202，高速无刷电机具有噪音小、运行平稳的优点。
参阅图1和图2，本体1内设置有PCB板4，PCB板4置于风扇2与吸风口组103之间的风道101内，PCB板4电连接有电源线7，电源线7与外部电源通电，以对本体1内的PCB板4、加热单元3、风扇2等电元件供电；加热单元3及风扇2均与PCB板4电连接，通过PCB板4对加热单元3及风扇2进行供电，且可通过PCB板4分别对加热单元3及风扇2进行控制，可在PCB板4上连接控制按钮以实现控制加热单元3的加热温度，使用方便。
参阅图2、图5、图6和图7，PCB板4上电性连接有用于控制加热单元3温度的控温机构，控温机构包括温度传感器51和电控开关52，温度传感器51置于加热单元3与吹风口102之间的风道101内，温度传感器51包括测温头，通过测温头对其周围空气进行测温，并将测得温度转化为电信号传递给PCB板4；当测得温度小于PCB板4程序的预设温度，则电控开关52控制加热单元3通电加热；当测得温度达到或超过PCB板4程序的预设温度时，则电控开关52控制加热单元3停止加热，以达到恒温的目的，防止加热单元3温度过高损伤头发；加热后头发周围带热量的空气从吸风口组103带入至风道101内，在风扇2的作用下流动至加热单元3处进行加热，提升加热效率；由于这部分空气本身带有热量，此时加热单元3能够适当降低功率来对这部分空气进行加热，使用更加节能；本实施例中预设温度可设为80-100℃范围内的一个温度，从而使得吹风口102所吹出的热风约为80-100℃。
参阅图1、图5、图6、图7和图8，加热单元3包括电热元件301以及与电热元件301接触的散热件302，散热件302与电热元件301接触进行热传导，以将电热元件301的热量散发至风道101内，避免电热元件301的热量无法及时传递至风道101内的空气；散热件302一体成型有多个用于对风道101内的空气进行导流的导流条3021，风扇2吹出的风沿导流条3021流动，使得吹过散热件302的空气流动更加平稳，从而使得吹过散热件302的空气受热均匀，进而使得吹风口102吹出的热风温度均匀以达到对头发的均匀加热；导流条3021同时能够增加与空气的接触面积，提升散热件302的散热效果；导流条3021包括凸条3022和凸筋3023，凸条3022一端与散热件302连接，凸筋3023一端与凸条3022连接，散热件302通过导流条3021增加与空气的接触面积，提升导热效果。
参阅图5、图7和图8，电热元件301为电加热棒，散热件302为中空状的散热管，凸条3022和凸筋3023均沿散热管轴线方向延伸；电热元件301套装在散热件302内侧，电加热棒的外壁与散热管的内壁接触进行导热，导热效果好，且电加热棒在散热管内不易发生晃动，工作稳定。
参阅图1-图4，本体1包括上夹板11以及可相对上夹板11浮动的下夹板12，上夹板11一端与下夹板12一端铰接；上夹板11的内腔与下夹板12的内腔通过通道6连通形成风道101，上夹板11上设置与上夹板11内腔连通的第一中空导柱114，下夹板12上设置有与下夹板12内腔连通的第二中空导柱123，第一中空导柱114插接至第二中空导柱123内侧，以使第一中空导柱114与第二中空导柱123连通，通道6形成于第一中空导柱114内侧；第一中空导柱114的向下延伸的长度大于第二中空导柱123向下延伸的长度，使得上夹板11与下夹板12在进行相对浮动的过程中第一中空导柱114与第二中空导柱123始终连通；吹风口102成型于下夹板12，吹风口102设置有多个且均倾斜设置于下夹板12上，使得头发受热均匀；吸风口组103包括第一吸风口111以及与第一吸风口111对应的第二吸风口121，上夹板11与下夹板12合拢时第一吸风口111置于第二吸风口121的正上方，第一吸风口111成型于上夹板11，第二吸风口121成型于下夹板12，第二吸风口121设置在吹风口102的一侧；直发时用右手握持住上夹板11与下夹板的铰接端，将头发置于另一端的上夹板11与下夹板12之间并稍稍夹紧，夹紧后对头发由上至下进行拉直；拉直过程中，吹风口102先对头发吹热风加热，再下拉本体1并与头发进行相对滑动，使得加热后的这部分头发位于第一吸风口111与第二吸风口121之间吸风，从而快速带走这部分头发的热量以达到定型的效果，保护发质且易于造型；参阅图2，箭头方向为空气流动示意方向。
参阅图1、图5、图6和图7，下夹板12上设置有第一隔套8以及与第一隔套8一端连接的第二隔套9，第二隔套9与吹风口102连通；加热单元3以及温度传感器51均置于第二隔套9内，风扇2置于第一隔套8内，使得风扇2吹出的风沿第一隔套8进入第二隔套9内，然后经加热单元3加热后从吹风口102吹出。
参阅图1和图9，下夹板12包括弧形凸起部122，上夹板11设置有与弧形凸起部122对应的弧形凹槽112，上夹板11与下夹板12合拢时，弧形凸起部122对应落入弧形凹槽112内，直发时将头发置于弧形凸起部122与弧形凹槽112之间，增加头发与本体1之间的摩擦力，便于拉直头发；吹风口102成型于弧形凸起部122上，便于在拉直头发的同时对头发进行吹热风加热；上夹板11开设有与吹风口102对应的通槽113，通槽113设置有多个，上夹板11与下夹板12合拢状态时，吹风口102所吹出的风能够经过通槽113贯穿上夹板11后吹出，避免吹风口102所吹出的风被上夹板11挡住导致流动不平稳吹散头发，使得吹风口102吹出的风更加平稳流畅，头发加热均匀。
本实用新型低温直发装置，拉直过程中，吹风口先对头发吹热风加热，再下拉本体并与头发进行相对滑动，使得加热后的这部分头发位于第一吸风口与第二吸风口之间吸风，从而快速带走这部分头发的热量以达到定型的效果；通过吹风口对头发吹出热风进行加热，通过吸风口对组加热后的头发降温定型，避免头发持续处于高温状态下受到损伤，使用安全可靠，且易于造型；加热单元包括电热元件以及散热件，散热件与电热元件接触进行热传导，以将电热元件的热量散发至风道内，避免电热元件的热量无法及时传递至风道内的空气；风扇吹出的风沿导流条流动，使得吹过散热件的空气流动更加平稳，从而使得吹过散热件的空气受热均匀以达到对头发的均匀加热；导流条同时能够增加与空气的接触面积，提升散热件的散热效果。
以上所述仅是本实用新型的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本实用新型技术原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本实用新型的保护范围。
