A particle collection container that is designed as a stand structure for a cyclonic pre-separator, can be positioned on a flat underlying surface in a stable manner, and has an open upper face on which the cyclonic pre-separator can be placed, includes a rectangular container base and four container peripheral walls which extend upwards from the container base and define a horizontal outer contour of the particle collection container. The horizontal outer contour defined by the container peripheral walls tapers towards the container base, and the particle collection container can be stacked into an identical particle collection container.

An energy storage module for use with an electric device in the shape of an electric hand-held machine tool or a vacuum cleaner, with the energy storage module having a wireless communication interface for wireless communication with an external communication apparatus arranged remote from the energy storage module and a module housing in which an electric storage device with at least one electrically rechargeable storage cell is arranged and on which a device interface is provided for detachable connection of the energy storage module to the electric device, with the device interface having electric device supply contacts for the electric energy supply of the electric device. The device interface of the energy storage module has a data interface separate from the device supply contacts, for data communication with the electric device.

An extraction connection system for portable machine tools includes at least one tool connection element, at least one suction apparatus connection element, and at last one fixing unit. The at least one tool connection element is configured to be connected to the at least one suction apparatus connection element. The at least one fixing unit includes at least one movably mounted fixing element configured to fix the at least one tool connection element and the at least one suction apparatus connection element against a movement relative to each other in at least one direction.

Industrial vacuum cleaner configured for servicing at least one construction tool (2), said vacuum cleaner (1) comprising a vacuum inlet (3), wherein said vacuum cleaner (1) further comprises a controller (8) and connected to said controller (8) a wireless transceiver (10), a memory (12), and at least one location and/or orientation sensor (11) configured for detection of vacuum cleaner location and/or localization of other objects in relation to the vacuum cleaner (1) and wherein the vacuum cleaner (1) further comprises means for propulsion (13) controlled by said controller (8).

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.

A particle receiving device for attachment to a particle outlet of a vacuum cleaner and/or of a cyclone separator and for receiving separated particles, including: a particle receiving volume for receiving the particles, an access element with an access element opening through which the particles can be transported into the particle receiving volume, and a closure element. The access element is selectively displaceable relative to the closure element into a closure position in which the closure element closes access opening, or into an open position in which the closure element releases the access element opening.

This electric work machine is provided with a wireless communication unit for performing wireless communication with another electric work machine and can be switched by a switching switch between a linked operation mode in which the electric work machine works together with another electric work machine, and an independent operation mode in which the electric work machine works alone. When the switch is switched from the independent operation to the linked operation mode, a control unit for the electric work machine automatically searches for another electric work machine with which the electric work machine can communicate, and transitions the work machines to a linked state when the other electric work machine is detected and pairing registration is possible. When another linkable electric work machine is not detected, the search is continued.

A dust collector for use with a hand-held power tool includes a housing, a suction pipe coupled to the housing, and an electric motor positioned in the housing. The dust collector additionally includes a suction fan driven by the electric motor and operable to generate a vacuum in the suction pipe, and a depth stop assembly. The depth stop assembly is configured to limit the axial movement of the suction pipe. The depth stop assembly is configured to be alternately positioned on opposite sides of the suction pipe in a first configuration and a second configuration, respectively.

A dust collecting device with an extendible and flexible air tube including a housing, a cover, an air tube, a dust collecting head, a filter material and a gas guiding device. The cover is detachably disposed on the housing and has an accommodating groove. The air tube is positioned in the accommodating groove and extendible and flexible, the air tube is capable of being extended to outside the accommodating groove and retracted to be accommodated in the accommodating groove, and a bending angle and an extension direction of the air tube is changeable by flexibility. The dust collecting head is disposed at the air tube, and is positioned in the accommodating groove when the air tube is shortened to be accommodated in the accommodating groove. The filter material is disposed inside the housing and close to the cover. The gas guiding device is disposed inside the housing.

A yard waste clearing device includes a horizontal cross-flow fan blade assembly. The cross-flow fan blade assembly is disposed in a housing that operated in concert to produce an airflow from an inlet portion of the housing, through the cross-flow fan blade assembly, and out an outlet portion with a sufficient flow rate to carry plant matter shredded by the cross-flow fan blade assembly to a storage element such as a disposable yard waste bag. A vertical chute from the outlet portion carries the shredded plant matter up to the opening of the yard waste bag so that the yard waste bag may be held vertically, utilizing the available storage space more efficiently.
