摘要： An added inertia resonant system (12) for a power toothbrush (10) comprises a drive shaft (16), a drive system (22), and at least one inertial weight member (24). The drive shaft (16) has a principal axis (26) that defines a center of rotation. The drive system (22) imparts a reciprocating motion to the drive shaft (16) about the principal axis (26). The at least one inertial weight member (24) couples to the drive shaft (16) and comprises a planar material having a complex shape balanced along an x-, y- and z-axis to enable the drive system (22) to achieve low power, high amplitude motion of the drive shaft (16) when placed under user loading. A method for providing added inertia in a resonant system for a power toothbrush is also disclosed.

摘要： A brush head for an oral care implement includes at least one (first) group of tufts extending from a mounting surface of a tuft carrier having a rotation axis. The tufts have a base end and a free end. The tufts of the first group are tufts having an extension in a circumferential direction about the rotation axis exceeding an extension in a radial direction. The tufts of the first group may be inclined with respect to the mounting surface in at least one direction. Each of the first-group tufts may comprise a first group of filaments and a second group of filaments, wherein the second-group filaments' free ends protrude beyond the first-group filaments' free ends.

摘要： A personal care appliance 10 comprises an actuator 14, a current sensor 28 for monitoring a driving current, and a controller 24. The actuator 14, operable according to a non-linear response characteristic 58 of amplitude versus frequency, includes a movable shaft 18 configured for resonant movement 38 in response to a drive signal 25, further for being coupled with a workpiece 20. The controller 24 (i) detects at least one of a plurality of different characteristic load states (100,102,104,106,108,110) in response to a perturbation in the monitored driving current 29 and (ii) actively delivers the drive signal 25 to the actuator 14 selected from at least two different drive signals (66,70) as a function of a detected characteristic load state. In this manner, the controller 24 implements self-adaptive amplitude regulation of the movable shaft's resonant movement 38 among the plurality of difference characteristic load states that include additional loads of force, spring, mass, and/or damping to a given load state of a resonant spring mass system of actuator 14 coupled with workpiece 20.

摘要： Disclosed is a multi-functional visual electric toothbrush, including a main unit, an oral viewer, an interdental cleaning appliance and an electric toothbrush head. The oral viewer is connected to the main unit, the interdental cleaning appliance is connected to the front end of the oral viewer, and the electric toothbrush head is connected to a toothbrush driving mechanism. A circuit system and a control system of the main unit can not only transfer the energy of a power supply to the toothbrush driving mechanism, so as to drive the electric toothbrush head to work for large-area oral cleaning, but also connect a lighting system, an observation system and a switch of the oral viewer to control the oral viewer to work. The interdental cleaning appliance may be used cooperatively with the oral viewer to perform targeted cleaning on difficult-to-clean food debris in an oral cavity.

摘要： A powered toothbrush includes a handle, a power source disposed in the handle, a head including a cavity disposed at a distal end of the handle, an electrically conducting element disposed in the cavity and electrically connected to the power source, and a movable cleaning element connected to the head and movable relative to the cavity. The movable cleaning element includes a tooth cleaning support member, a tooth cleaning element mounted on the support member, and a ferromagnetic member. Application of an electrical current to the electrically conducting element generates a magnetic field at the electrically conducting element. The magnetic field selectively at least one of attracts and repels the ferromagnetic member to move the movable cleaning element relative to the electrically conducting element.
