Suction device for separating particle in suction flow from handheld machine tool, has suction communication device with suction channel to transmit leadless control signal and alarm signal to external communication device of hand tool

摘要

The suction device (10) has a hand tool (80) that is provided with a drive motor (81) for driving a tool portion (82). A suction communication unit (40) of suction housing (11) is wireless-communicated with an external communication device (50) of hand tool. A suction device receiver (41r) of suction communication device is arranged to receive leadless control signal (51) and alarm signal (101,201) from external communication device. A suction channel (41s) is arranged to transmit leadless control signal (108) and alarm signal (105) to external communication device.
