Abstract: An accessory device for a hand-held power tool includes a dust collection box that has a housing and a filter unit configured to filter an airflow. The housing is configured to be connected to a housing of the accessory device via a first securing unit. The filter unit is configured to be connected to the housing of the dust collection box via a second securing unit. The filter unit has a first sealing element arranged on the dust collection box side and a second sealing element arranged on the accessory device side. The filter unit is sealed from the housing of the dust collection box and the housing of the accessory device via the first and second sealing elements. The hand-held power tool in one embodiment is configured with a percussive mechanism.

Abstract: The disclosure relates to a dust suction device for a hand-held power tool, comprising a housing, a fan unit accommodated in the housing for generating an air volume flow, at least one suction opening for suctioning off drill cuttings from a borehole, and at least one suction intake opening for generating a negative pressure in an adhesion region between the dust suction device and a workpiece on the basis of the air volume flow.

Abstract: A power-tool cooling apparatus for a portable power tool includes a first fan configured to generate a first cooling fluid flow to cool a drive unit of the portable power tool, and a second fan that generates a further cooling fluid flow to cool an electronics unit of the portable power-tool. A third fan generates a third cooling fluid flow to cool a second electronics unit of the power-tool, and supplies cooling fluid to the first cooling fluid flow.

Abstract: A rechargeable battery pack for a hand-held power tool, including a rechargeable battery pack housing, the rechargeable battery pack housing accommodating at least two rechargeable battery cells. The rechargeable battery pack is mechanically and electrically connectable to a hand-held power tool and/or to a charging device via an interface. The interface includes contact elements for electrically and/or mechanically contacting corresponding countercontact elements on the hand-held power tool and/or corresponding countercontact elements on the charging device. It is provided that the rechargeable battery pack housing includes at least one first rechargeable battery cell string for accommodating at least one first rechargeable battery cell, and at least one second rechargeable battery cell string for accommodating at least one second rechargeable battery cell. The rechargeable battery pack housing includes at least two electrical contact elements for each rechargeable battery cell string.
