可选的，结合图5、图6所示，所述第一热传导组件62还包括第一铜传导片623，所述第一铜传导片623设置在所述第一铝传导片621与所述第一制 冷体64之间。
其中，第一制冷体64的数量为两个，且并排设置，且两者靠近第一铝传导片621的一侧相互齐平设置；第一铜传导片623的材质为铜片，铜片一般为长方形或圆形，成本较低，除此之外，还可选用其他导热性能好的材质；铜片的热传导效果很好，且铜片较软，具有一定的延展性，在第一铝传导片621与第一制冷体64的相互挤压下能发生延展变形，使得铜片的两侧面分别与第一铝传导片621和第一制冷体64的接触面积尽量大，防止能量在传递过程中流失，从而确保整体的导热效果更好，提升能量传递效率。
可选的，结合图5、图6、图7所示，所述手柄1内还设置有用于给所述第一电路板61供电的电池5，所述手柄1上设置有与所述第一电路板61连接的电量显示灯11。
其中，电池5为充电电池5，电量显示灯11用于显示电池5的电量，电量显示灯11暴露于手柄1的壳体进行设置，以便使用者可以及时观察电池5的使用情况，方便及时进行充电操作。
可选的，结合图5、图6、图7所示，所述手柄1上还设置有与所述第一电路板61连接的开关按钮12。
其中，开关按钮12暴露设置于手柄1的壳体表面；当需要将刀片3降温时，使用者按下开关按钮12，第一电路板61控制第一制冷体64进行制冷工作，当降低到一定温度时，第一铜传导片623上的能量被吸收到第一制冷体64上，第一铜传导片623温度降低，第一铝传导片621的能量被吸收到第一铜传导片623，第一铝传导片621温度降低，第一钣金连接头622的能量被吸收到第一铝传导片621，第一钣金连接头622的温度降低，刀片3上的能量再被吸收到第一钣金连接头622上，最终使得刀片3的温度下降。
本实用新型实施例还提供了一种具有变温功能的手动剃须刀，结合图9、图11所示，括相互连接的手柄1和刀架2，所述刀架2安装有刀片3，所述手柄1设置有制热结构7，所述制热结构7和所述刀片3相互热传导连接。
其中，刀片3由导热材质制作而成，如由金属材质或陶瓷材质制作而成，其具有较佳的导热性能；手柄1用于使用者剃须时握持用，刀架2安装在手 柄1的一端，手柄1和刀架2一般由塑料等绝缘材质制作而成；制热结构7可被控制进行制热工作，具体工作可根据使用者的需要进行选定；刀片3的温度可依靠制热结构7的温度的改变而改变，使得刀片3通过制热结构7的制热就能实现升温。
本实施例中的具有变温功能的手动剃须刀，在手柄1设置具有制热功能的制热结构7，且制热结构7与刀片3之间直接热传导连接，使得用于剃须的刀片3的温度随着制热结构7的温度的改变而改变，从而使得使用者在寒冷冬季使用时可启动制热功能，此时温热的刀片3能减少对皮肤的刺激，并有助于皮肤毛孔的扩张，使剃须效果更佳；这种结构设计，不仅部件尽量少，成本低，且整体结构紧凑，占用空间小。
可选的，结合图9、图10、图11所示，所述制热结构7包括第二电路板71、第二制热体73和与所述刀片3连接的第二热传导组件72，所述第二制热体73与所述第二电路板71电连接，且与所述第二热传导组件72热传导连接。
其中，当需要加热刀片3时，第二电路板71控制第二制热体73进行制热工作，当达到一定温度时，第二制热体73上的能量传导至第二热传导组件72，第二热传导组件72温度上升，第二热传导组件72上的能量再传递至刀片3，最终使得刀片3温度上升。
可选的，结合图9、图10所示，所述第二制热体73为制热半导体。
其中，制热半导体的制热，是应用温差电效应的结果；当有电流通过制热半导体时，就会在一端发热、另一端降温产生温差，即一端制热、另一端制冷，制热半导体的制热端与第二热传导组件72连接。
可选的，结合图9、图10、图11所示，所述手柄1内还设置有用于给所述第二电路板71供电的电池5，所述手柄1上设置有与所述第二电路板71连接的电量显示灯11。

可选的，结合图9、图10、图11所示，所述手柄1上还设置有与所述第 二电路板71连接的开关按钮12。
其中，开关按钮12暴露设置于手柄1的壳体表面；当需要加热刀片3时，使用者按下开关按钮12，第二电路板71控制第二制热体73进行制热工作，当达到一定温度时，第二制热体73上的能量传导至第二铜传导片723，第二铜传导片723将能量传递至第二铝传导片721，第二铝传导片721将能量传导至第二钣金连接头722，第二钣金连接头722上的能量再传递至刀片3，最终使得刀片3温度上升。
可选的，结合图9、图10、图12所示，所述第二热传导组件72包括相互连接的第二铝传导片721和第二钣金连接头722，所述第二钣金连接头722与所述刀片3抵接。
其中，第二铝传导片721的材质为铝，铝的质量轻，成本也低，还不易被氧化，且具有较佳的导热性能，除此之外，还可选用其他导热性能好的材质；第二钣金连接头722为不锈钢材质，由钣金工艺加工而成，其具有一定的弹性和韧性，形状呈弯曲的马蹄形结构，当刀架2相对于手柄1转动的过程中，第二钣金连接头722能始终与刀片3上的热传导支架31保持接触，第二钣金连接头722具有导热性能，能与刀片3之间进行热传导。
本实施例中，设置第二钣金连接头722，一方面，第二钣金连接头722具有一定的弹性和韧性，使得刀架2能顺利相对于手柄1转动，因此可以将刀架2设计为能相对于手柄1转动的结构，以方便用户使用，另一方面，第二钣金连接头722具有较佳的导热性能，刀架2相对于手柄1转动的过程中能始终保持热传导结构与刀片3相互接触，能确保有效控制刀片3进行升温。
可选的，结合图9、图10、图12所示，所述第二热传导组件72还包括第二铜传导片723，所述第二铜传导片723设置在所述第二铝传导片721与所述第二制热体73之间。
其中，第二制热体73的数量为两个，且并排设置，且两者靠近第二铝传导片721的一侧相互齐平设置；第二铜传导片723的材质为铜片，铜片一般为长方形或圆形，成本较低，除此之外，还可选用其他导热性能好的材质；铜片的热传导效果很好，且铜片较软，具有一定的延展性，在第二铝传导片 721与第二制热体73的相互挤压下能发生延展变形，使得铜片的两侧面分别与第二铝传导片721和第二制热体73的接触面积尽量大，防止能量在传递过程中流失，从而确保整体的导热效果更好，提升能量传递效率。
可选的，结合图9、图10所示，所述手柄1和所述刀架2相互铰接连接。
其中，手柄1一端的两侧分别设置有转轴，刀架2上设有与转轴配合的安装孔，转轴和安装孔相互配合后，刀架2受力时可相对于手柄1转动；本实施例中，将手柄1和刀架2设计为相互铰接的结构，使得安装有刀片3的刀架2能相对于手柄1转动，以方便使用者在各个部位进行剃须操作。
可选的，结合图9、图10、图12所示，所述刀片3连接有热传导支架31，所述刀片3通过所述热传导支架31与所述制热结构7热传导连接。
其中，刀片3的数量具有多个，刀片3之间相互平行间隔设置；热传导支架31呈7字型结构，数量为两个，每个热传导支架31与每片刀片3连接，使得热传导支架31接收到的能量能有效传递至各个刀片3，又能保证刀片3和热传导支架31的整体结构质量尽量小；热传导支架31由金属或陶瓷等导热材质制作而成，具有较佳的导热性能；本实施例中，在刀片3与制热结构7之间增设热传导支架31，使得刀片3的受热或受冷时的温度变化更加稳定均匀，以提升用户体验感。
可选的，结合图9、图10、图12所示，所述刀片3与所述热传导支架31一体成型设置。
其中，其中一个刀片3和热传导支架31一体成型设置，其他刀片3可以通过焊接或粘接的方式与热传导支架31连接，既能节约安装步骤，又能确保刀片3与热传导支架31之间的热传递效果。
