ABSTRACT:
A blender with a safe starting function includes a motor unit, a blade base and a container. The motor unit has an insert groove and a micro switch. The blade base has a hole, a threaded rod, a spring and an actuating member with a press member and an actuating arm. The container has its bottom pressing the press members. In using, the blade base is positioned to let the actuating arm slide in the insert groove and press the micro switch to keep the blender in an on-power position. Then a user presses the on-off button to start the blender. If the blade base is rotated only for a very small angle from the on-power position to an off-power position, with the actuating arm separating from the micro switch, then the blender is in an off-power condition, impossible to be started even the on-off press button should be pressed.
