Abstract: A toothbrush comprises a head including a plurality of cleaning elements attached to the head, a handle, a neck extending between the head and the handle, a motor unit including a motor and a manual winder for manually energizing the motor, and a force sensor configured to detect a user-applied force exceeding a predetermined threshold force, wherein the force sensor causes the toothbrush to produce at least one of an audible signal and a tactile signal when the user-applied force exceeds a predetermined threshold force. An audible signal and a tactile signal may comprise, respectively, muting of the motor and interruption of vibration of the toothbrush.

Abstract: An oral care implement (1) comprising: an electrode pair with an impedance formed therebetween when electrified; a frequency generator, electrically connected to the electrode pair, for applying a voltage with at least two different frequencies between the electrode pair; an impedance measurement unit, electrically coupled to the electrode pair, for measuring impedance values between the electrode pair at least at the different frequencies; and a contact determination unit, in communication with the impedance measurement unit, wherein the contact determination unit comprises a memory for storing a function, wherein the function correlates impedance values of a defined oral area at the different frequencies, and wherein the contact determination unit comprises a processor for processing the measured impedance values to the stored function so as to determine contact information of the electrode pair with the defined oral area.

Abstract: A replacement toothbrush head includes a movable functional element comprising either a piston or a piston chamber; and a fixation element comprising either a piston when the movable functional element comprises a piston chamber; or a piston chamber when the movable functional element comprises a piston. The piston chamber engages the piston to form a pump; and the movable functional element is structured and configured to oscillate relative to the fixation element.

Abstract: A personal hygiene implement comprises an axle that extends along a first longitudinal axis; a movable functional element comprising a base comprising a first side and an opposing second side, a first pillar extending from the first side of the base, wherein the first pillar comprises a piston chamber that is fluidly connected to a discharging through-hole, and at least one cleaning element extending from the second side of the base; and a fixation element comprising a piston which extends orthogonally to the first longitudinal axis; wherein the movable functional element is capable of rotatably oscillating around the axle, and the piston chamber engages with the piston to form a pump.

Abstract: A handle for a small electric handheld appliance in which the handle comprises a motor assembly disposed in the handle. The motor assembly comprises a generally L-shaped magnetic yoke formed from two substantially perpendicular surfaces, such that the two substantially perpendicular surfaces define a concave receiving portion. The motor assembly also comprises an iron core and a coil winding disposed substantially in the concave receiving portion, such that the iron core and the coil winding are free from contact with one of the two substantially perpendicular surfaces when the motor is at rest.
