A dust hood for a power tool, wherein the dust hood includes an extraction region in which a suction hose coming from a dust-sucking device opens into the dust hood. The dust hood has a curvature in the extraction region, wherein the curvature makes it possible for an impulse surge which is generated within a filter cleaning operation of a dust-sucking device to be attenuated by reflection.

Dust hood for a power tool

An apparatus for receiving a functional unit for a power tool, wherein the receiving apparatus can be fastened to the power tool by way of a fastening mechanism. A second aspect of the invention relates to a method for fastening a receiving apparatus of this kind to a power tool. In the fastening mechanism, a rotatable insert part can be inserted into an opening of the receiving apparatus and can be moved from an unfastened to a fastened state by this rotational movement. In the fastened state, a hook of the power tool engages with a raised portion of the insert part.

Apparatus for receiving a functional unit for a power tool and method for fastening a receiving apparatus of this kind to a power tool

A vacuum cleaner () having a housing (') and at least one battery () arranged therein, and/or at least one battery compartment () that serves to hold at least one battery (). The vacuum cleaner () has a vacuum generator () that serves to generate an air stream along a flow path (A), wherein the at least one battery () or the at least one battery compartment () is arranged in said flow path (A).

Vacuum cleaner with a temperature-controlled battery

A mobile electric appliance is disclosed. The mobile electric appliance includes at least one battery bay for accommodating a battery with at least one voltage-generating cell and a battery-side charge status indicator, an electrical consumer, a power connector, as well as a charging device for charging the at least one battery. In addition, the mobile electric appliance includes means for detecting the charge status of the at least one battery and a device-side charge status indicator arranged on the mobile electric appliance. The battery may also include an interface, which is prepared to relay the charge status determined to an external processing unit.
