  • Publication number: 20200146796
    Abstract: An actuator (12) for a personal care appliance (10) having an eccentric core (21) to preload the actuator (12) to prevent rattling caused by detrimental reactionary forces. The eccentric core (21) includes a pole assembly (24) radially extending from a spindle 22 having at least a first set (25-1) and a second set (25-2) of pole members. The first set (25-1) has a greater length as measured from the center of the spindle 22 than the second set (24-2), reducing the magnet gap on one side of the spindle (22) to create an eccentric core and preload the actuator (12). Alternatively, the preload can be mechanically created by a set of bearings (28) disposed within housing (18) of the actuator 12, where the bearings (28) have a centerline (A3) offset from the principal axis (A1) of the housing (18).

  • Patent number: 10642948
    Abstract: The appliance includes a jet source of fluid, and a nozzle assembly through which the fluid is directed and then out for application to the teeth. A flow interrupter assembly is mounted within the nozzle assembly, such that the interrupter assembly is responsive to the fluid flow to produce momentary successive interruptions of the fluid flow by the action of the interrupter assembly moving from an original position to a flow interrupting position and then returning to its original position as the flow decreases and then is interrupted, due to the fluid flow itself, resulting in a cyclical perturbation in the fluid flow from the nozzle, by flow action alone.

  • Patent number: 10477959
    Abstract: A method (200) for manufacturing a brush head (100). The method includes the steps of providing a plurality of polypropylene bristle tuft retention rings (50), and inserting a respective nylon bristle tuft (21) into each of the bristle tuft retention rings. Heat is applied to each bristle tuft proximal end (23) at a temperature sufficient to at least partially melt the bristle tuft proximal end and create a proximal head portion (26). The platen (42) of the brush head is positioned in relation to the retaining rings (50) and proximal head portions (26) to define a space (92) in relation to the proximal head portions for injection of a thermoplastic elastomer, and the thermoplastic elastomer is injected into the space to create an elastomeric matrix (30) that at least partially encompasses the neck and the proximal head portions.
