Abstract
One aspect of the present disclosure provides a handheld grinder including a housing, a power port, a motor, a chuck, an illuminator, a first manual operating device, and a control circuit. The housing extends along a first direction. The first manual operating device is arranged in a region of the housing between the motor and the power port along the first direction. The first manual operating device receives a first manual operation. The control circuit sets an operation mode of the illuminator to either a light-on mode or a light-off mode in response to the first manual operation.
Claims22
A handheld grinder comprising:
- a housing (i) extending along a first direction and (ii) including an outer surface and a grip, the grip being configured to be gripped by a user of the handheld grinder;
- a power port (i) arranged on the outer surface of the housing and (ii) configured to receive an electric power from a power source;
- a motor (i) housed in the housing and spaced apart from the power port in the first direction and (ii) configured to be driven by the electric power received by the power port;
- a chuck configured to detachably attach a machining tool, the machining tool (i) being configured to grind and/or polish a workpiece, the machining tool (ii) including a support shaft having a rod shape, the chuck being (i) spaced apart from the motor in the first direction, (ii) configured to detachably attach the support shaft of the machining tool, and (iii) configured to be rotated by the motor;
- an illuminator configured to emit light onto the machining tool and/or the workpiece in contact with the machining tool;
- a first manual operating device (i) arranged in a region of the housing between the motor and the power port along the first direction and (ii) configured to receive a first manual operation, the first manual operation being performed to selectively set an operation mode of the illuminator to either a light-on mode or a light-off mode;
- and
- a control circuit configured to (i) set the operation mode to the light-on mode or the light-off mode in response to the first manual operation, (ii) control the illuminator not to emit the light based on the operation mode being set to the light-off mode, and (iii) control the illuminator to emit the light based on the operation mode being set to the light-on mode.
A method for controlling an illuminator for a handheld grinder, the method comprising:
- arranging a manual operating device between a motor and a power port of the handheld grinder, the power port being configured to receive an electric power for driving the motor, the motor being configured to drive a chuck, the chuck being configured to detachably attach a machining tool capable of grinding and/or polishing a workpiece, the manual operating device being configured to receive a manual operation, the manual operation being performed to selectively set an operation mode of the illuminator of the handheld grinder to either a light-on mode or a light-off mode, the light-on mode is a mode in which the illuminator emits light onto the machining tool, the light-off mode is a mode in which the illuminator does not emit the light;
- and
- setting the operation mode in response to the manual operation received by the manual operating device.
