Technical Problem

现有的割草机无法及时的控制板和电机进行散热，因此导致割草机的工作效率降低

Benefits of technology

[0040]因此，本发明提出一种动力头和园林工具，该动力头可以包括壳体，壳体包括对称设置的第一壳体和第二壳体，第一壳体和第二壳体的上均设置外部进风孔。在壳体上设置盖体，第一壳体，第二壳体和盖体即形成第一腔体，冷却气流通过外部进风孔进入第一腔体内。本发明还在壳体上设置有支撑座，在支撑座的两端设置有内部进风孔，同时壳体上还包括导风板，导风板向支撑座的内部延伸，同时导风板连接内部进风孔，当在支撑座上设置控制组件时，控制组件和导风板即可形成第二腔体，同时控制组件上的散热片和控制元件也位于第二腔体内，进入第一腔体内的冷却气流可以通过内部进风孔进入第二腔体内，同时由于导风板的作用，冷却气流可以与散热片和控制元件充分接触，从而有利于控制元件和散热片快速散热。在壳体的底部设置有电机组件，电机组件上设置有出风孔，电机组件和导风板形成第三腔体，由于导风板形成通风间隙，因此可以连通第二腔体和第三腔体，因此冷却气流可以进入第三腔体内。本发明中电机至控制组件的高度可以大于100mm，因此可以对经过控制元件和散热片的冷却气流进行充分降温，然后冷却气流在进入电机组件内部，从而实现对电机组件的散热，冷却气流最后通过出风孔流出外部，从而使得该动力头处于较稳定的工作温度内，因此可以提高该园林工具的工作效率。
