Abstract: A multi-purpose cleaning appliance avoids the need for separate appliances for vacuuming and mopping, and includes a floor tool body including a base and wheels for supporting the floor tool body on a floor with the base above the floor; and a mopping module and a vacuum cleaner module that are interchangeably mountable to the floor tool body for mopping or vacuuming the floor respectively, with the mopping module configured to perform wet mopping.

Abstract: A modular handheld electric tool system comprises a handle, a motor module and a tool head. The handle includes a handle housing with an elongate portion configured to provide a grip, a handle electrical coupling on the handle housing, a circuit including a tool switch in the handle housing, the tool switch connected between a power supply and the handle electrical coupling. The motor module including a motor casing that holds an electric motor, a motor electrical coupling on the motor casing that is complementary to the handle electrical coupling and electrically connected to the electric motor, and a rotary output mounted to the motor casing and driven by the electric motor.

Abstract: A personal air conditioning apparatus includes a centrifugal fan received within a scroll casing. A container mounted to the inlet of the scroll housing is provided for receiving and holding a coolant member. The scroll casing is supported upon a base enclosing two liquid reservoirs and a battery compartment. A liquid atomizing device fed from one of the reservoirs dispenses liquid droplets into air flow from a discharge passage. A channel extends between the container and the other of the reservoirs for draining away condensation formed on the coolant member. The scroll casing defines the discharge passage, which has a cross-sectional area that increases toward an outlet at an end of the scroll casing. Axially opposing faces of the discharge passage are divergent, and the cross section of the discharge passage adjacent the outlet has a shape elongated substantially in the axial direction.
