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.

Force-sensing toothbrush

An oral care implement () 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.

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.

A therapeutic micro-current delivery device includes a first electrode in electrical contact with a user at a first user location, a second electrode in electrical contact with the user at a second user location, a power source operable to provide a first voltage potential at the first electrode and a second voltage potential at the second electrode, and a micro-current control circuit in electrical communication with the first electrode, second electrode and power source. Electrical contact of the first electrode at the first user location and electrical contact of the second electrode at the second user location completes an electrical circuit. The micro-current control circuit generates a micro-current Ithrough a user between the first location and the second location that increases from a start current Ito an end current Iover a rise time t. Oral care devices and micro-current control methods are also disclosed.

Therapeutic micro-current delivery devices and methods thereof

Embodiments of the present disclosure are directed to oral care devices, system and methods for advanced ionic micro-current control. In some embodiments, an oral care device is actuated upon completion of an electric circuit by a users hand and oral cavity. The electrode on an oral care implement may be configured to lose conductivity over time to indicate a replacement oral care implement is need. In some embodiments, a controller of the oral care device may detect the type of oral care implement and control the ionic micro-current accordingly. Additionally, embodiments may detect a region within the oral cavity that the oral care device is in contact with and apply the ionic micro-current accordingly. Further, in some embodiments, the health status of various regions of a user's oral cavity may be detected and monitored over time.

Oral care devices having automatic mode selection

An electric motor for operating a small electric device is disclosed. The electric motor includes at least one first oscillatory motor component; an inductor for producing a magnetic field; and a first magnet arrangement including a first permanent magnet that generates a force for activating a rotatory oscillating movement (R) of the at least one first oscillatory motor component around a rotating axis (z). The at least one first oscillatory motor component and the first magnet arrangement are configured such that a magnetic reluctance torque acting between the first oscillatory motor component and the first permanent magnet operates as a righting moment for the rotatory oscillating movement (R).
