Abstract
A handheld band saw includes a housing assembly including a battery pack mounting portion for mounting a battery pack, a rotating wheel assembly at least partially disposed in the housing assembly and including a first rotating wheel and a second rotating wheel, where the first rotating wheel and the second rotating wheel are configured to be substantially symmetrical about a midplane, an electric motor disposed in the housing assembly and capable of driving one of the first rotating wheel and the second rotating wheel to rotate, a fan which is capable of generating at least one airflow in the housing assembly, and a control circuit board disposed in the housing assembly.
Claims15
A handheld band saw, comprising:
- a housing assembly comprising a battery pack mounting portion for mounting a battery pack and a main handle formed with an accommodating space;
- a rotating wheel assembly at least partially disposed in the housing assembly and comprising a first rotating wheel and a second rotating wheel, wherein the first rotating wheel and the second rotating wheel are configured to be substantially symmetrical about a midplane;
- an electric motor disposed in the housing assembly and capable of driving one of the first rotating wheel and the second rotating wheel to rotate;
- a fan which is capable of generating an airflow in the housing assembly during rotation;
- and
- a control circuit board disposed in the accommodating space of the housing assembly,
- wherein the control circuit board is disposed on a side of the midplane facing the electric motor, the electric motor and the battery pack mounting portion are located on two sides of the midplane, the housing assembly is formed with an air inlet and an air outlet and, when the fan rotates, the airflow entering the housing assembly from the air inlet flows through at least the control circuit board and the electric motor.
