Abstract
A dust collecting system includes a power tool and a dust collector. The power tool is configured to perform processing operation on a workpiece by driving a tool accessory. The dust collector is configured to collect dust generated by the processing operation. The power tool includes a first motor and a driving mechanism configured to drive the tool accessory by power of the first motor. The dust collector includes a second motor and a fan configured to be rotationally driven by the second motor to generate air flow for collecting dust. The dust collecting system includes a first control device configured to control a rotation speed of the second motor according to a driving state of the power tool.
Claims14
A dust collecting system including a power tool configured to perform a processing operation on a workpiece by driving a tool accessory and a dust collector configured to collect dust generated by the processing operation, wherein:
- the power tool comprises:
- a first motor;
- and
- a driving mechanism configured to drive the tool accessory by power of the first motor;
- the dust collector comprises:
- a second motor;
- and
- a fan configured to be rotationally driven by the second motor to generate air flow for collecting the dust;
- the dust collecting system comprises a first control device configured to change a rotation speed of the second motor according to a driving time of the first motor from a start of driving of the first motor;
- and
- the first control device is configured to increase the rotation speed of the second motor as the driving time increases.
