The mouthpiece appliance includes an assembly for receiving teeth () which includes a plurality of cleansing portions, typically two opposing side portions () and an intermediate center portion (). The brushing portions include bristle sections which are adapted to clean teeth. The appliance includes at least one DC motor assembly () with an output shaft with an eccentric mass of crankshaft (). The appliance further includes a mechanical motor cover comprising a plurality of arm members which are arranged to connect the DC motor assembly to the cleansing portions of the appliance so that as the unbalanced weight on the output shaft rotates, movement of the cleansing portions, toward and away from the teeth or along the surfaces of the teeth occurs, producing cleansing of the teeth.

Mouthpiece for cleaning teeth with a mechanical drive train

A magnetic actuator system which includes a case () and a spindle () which extends through the case comprising a magnetizable material such as iron. The actuator further includes a pair of permanent magnet assemblies () positioned fixedly within the casing with a longitudinal space there between, wherein the permanent magnet assemblies comprise an alternating plurality of north pole/south magnet sections () which extend longitudinally or circumferentially of the actuator. The actuator further includes a coil winding () which surrounds the spindle, positioned between the two permanent magnet assemblies. Magnetic pole assemblies () attached to the spindle are positioned within the volume encompassed by the permanent magnet assemblies, such that an alternating drive signal produces an oscillating action of the spindle of desired frequency and amplitude.

Resonant actuator using magnetic action for a power toothbrush

A device for performing a process of treating a liquid including a detachably arranged liquid treating unit and a basic part which is suitable for receiving and accommodating the liquid treating unit. The liquid treating unit has an air restriction for taking in air to be used in the liquid treating processes, wherein the air restriction includes a pin and a hole for receiving the pin. The pin is rotatably arranged in the hole, and means are provided for causing a rotation of the pin in case of a movement of the liquid treating unit relative to the liquid treating device.
