Abstract: Improved cooling systems for handheld devices are disclosed. In some aspects, the cooling system may utilize air inlets disposed behind a guard to prevent debris or liquids from entering the handheld device and potentially causing damage to internal components of the handheld device. In aspects, a vents may be disposed on the guard to divert cooling air into a housing of the handheld device to cool internal components, such as the motor or a printed circuit board (PCB). In additional or alternative aspects, a motor mount may be provided that includes ribs defining air channels to divert or direct cooling air to components to be cooled. The air channels provided by the motor mount may enable the cooling air to reach portions of the internal components that may be distant from the air inlets of the housing.

Abstract: The utility model discloses a long-rod-type electric tool, comprising: a handle assembly, the handle assembly comprising a power supply unit; a machine head assembly, the machine head assembly comprising a driving unit and an operating unit connected to the driving unit; a long rod assembly, the long rod assembly being arranged between the handle assembly and the machine head assembly; and at least one interface. The long-rod-type electric tool is configured to make an orientation of the operating unit relative to the long rod assembly adjustable in at least one degree of freedom by means of the at least one interface.

Abstract: An electric power sprayer has a battery system with a battery interface and a voltage transformer. The battery interface may receive a plurality of different batteries having different voltages. The voltage transformer is operatively-connected to the battery interface and converts the different voltages into a standard voltage.

Abstract: A clip construction is provided for an article housing, e.g., a cordless telephone housing, which is movable between a deployed position, and a retracted position, in which the surface of the clip is disposed flush with the outer surface of the housing.
