Abstract: A dental cleaning appliance includes a handle and a fluid delivery system. The fluid delivery system includes a nozzle for delivering a burst of working fluid to the teeth of a user, and a moveable fluid conduit which is moveable about an axis relative to the handle. The nozzle is moveable with the fluid conduit, which is biased for movement about the axis in a direction which urges the nozzle against a user's teeth during use of the appliance.

Abstract: A dental cleaning appliance includes a handle and a fluid delivery system. The fluid delivery system includes a nozzle for delivering a burst of working fluid to the teeth of a user. A contact member for engaging the teeth of the user is moveable relative to the nozzle as the appliance is moved along the teeth of the user. A sensor provides an output which varies with movement of contact member relative to the nozzle. A control circuit actuates the delivery of working fluid to the teeth of the user depending on the output from the sensor.

Abstract: A domestic appliance includes an electric motor; a switch assembly for selectively connecting the motor to a power source; a handle; and a manually-operable trigger movable relative to the handle between an active position and a passive position. The trigger and the switch assembly are arranged such that the switch assembly is in a motor-connecting state when the trigger is in the active position, and is in a motor-disconnecting state when the trigger is in the passive position. The domestic appliance comprises a first biasing member which is arranged to urge the trigger away from the passive position and towards the active position.

Abstract: A dental cleaning appliance includes a handle, and a cleaning tool detachably connected to the handle. The cleaning tool includes a nozzle for delivering a burst of working fluid to the teeth of a user, a stem extending between the handle and the nozzle, and a fluid reservoir for storing working fluid. The fluid reservoir is connected to, and extends around, the stem.
