An electric toothbrushing device is disclosed, the device comprising means (16) for producing vibration of a toothbrush head (14), means (24, 32, 40, 42, 44) for producing an orientation signal indicating of an area of the mouth being brushed, and means (47, 48, 49) for producing a pressure signal indicating a pressure applied to the toothbrush head. The device further comprises processing means (46) arranged to link values of the orientation signal with values of the pressure signal in order to provide feedback to a user regarding a brushing pressure applied to each of a plurality of different areas of the mouth. By linking values of the orientation signal with values of the pressure signal, the user can be better informed about which parts of the mouth are being or have been brushed too hard. This can help the user to correct their brushing technique.

An oral cleaning and/or treatment unit (10), e.g. a head for an oral cleaning and/or treatment device, includes electrodes (18a, 18b) for emitting RF energy for providing an oral cleaning and/or treatment function. The unit includes at least a first (14a) and second (14b) protruding member, which protrude in a same general direction away from a base or support structure (12). Each comprises one or more electrodes for generating an RF field. The protruding members are adapted to have a flexibility that permits the member to resiliently bend or deform in a direction perpendicular the direction of extension of the member out of the support surface (‘lateral direction’).

A vibrating toothbrush and an eccentric shaft are proposed. The vibrating toothbrush includes a head in which bristles are planted, and a handle from which a head coupler protrudes, the head being detachably coupled to the head coupler. The toothbrush includes an electric motor accommodated in the handle to generate rotating force; and an eccentric shaft rotatably connected to the electric motor, at least a portion thereof being eccentric to generate vibration and thereby transmit vibration to the head coupler. The eccentric shaft includes a motor fixing part connected to the electric motor; an eccentric weight configured to be offset from a rotation center of the electric motor; and a rotating shaft formed of a metal material, and connecting the motor fixing part and the eccentric weight.

An applicator device including at least one holding section, at least one working tip, and a neck section connecting the holding section and the working tip, the device also includes a base body formed at least partially from a first plastic component, the base body being at least partially overmolded by at least one second plastic component that is softer than the first plastic component. In the region of the working tip, the at least one second plastic component at least partially coats the base body, and the coating includes outwardly projecting, bristle-type cleaning elements.

An oral care apparatus that includes an oral care implement and a tracking module detachably coupled to the oral care implement. The oral care implement includes a body having an inner surface that defines an internal cavity. The tracking module may be coupled to the oral care implement by inserting a portion of the tracking module into the internal cavity of the body. The tracking module includes a coupling portion and an electronics portion that are coupled together so as to be fixed together in the axial direction but freely rotatable relative to one another. The tracking module may only be able to be inserted into the internal cavity of the body in a single orientation. Furthermore, when in the internal cavity, the electronics portion of the tracking module may be non-rotatable relative to the body while the coupling portion of the tracking module remains rotatable relative to the body.

A system and method for instant tongue sampling and diagnosis includes acquiring a plurality of tongue images from a plurality of digital oral devices, and a current health conditions, building a diagnosis framework for diagnosing a current health condition of a user by: i) analyzing the collected tongue images with a visual recognition engine to determine tongue characteristics of each tongue captured in the tongue images, and ii) correlating the tongue characteristics with the current health condition, identifying tongue characteristics from a received image of the tongue using the visual image recognition engine, applying the diagnosis framework to the tongue characteristics of the tongue to diagnosis the current health condition of the user, and modifying a graphical user interface of the digital oral device to display a custom health report indicative of the current health condition of the user, in response to applying the diagnosis framework.

A method includes determining a position of a skincare device with respect to a body part of a user via one or more sensors on the skincare device, the skincare device configured to apply a treatment to the user's body part; obtaining a location of a target area on the body part having a condition for application of the treatment; adjusting a parameter of the skincare device according to the location of the target area and based on the condition.

An oral care method using an electric toothbrush includes receiving brushing data from an electric toothbrush, by an application; and analyzing the brushing data by the application to display a brushing score indicating how much the brushing is performed.

An toothbrush having a handle and a head. The handle may include a first component and a second component covering at least a portion of the first component. The first and second components may be chemically compatible. The first and second components may both comprise a hard polyolefin. The first and second components may have different transparencies. In one aspect, the first component may be opaque and the second component may be transparent or semi-transparent. In some aspects, the handle may also include a third component comprising a thermoplastic elastomer. Furthermore, there may be at least one projection extending outwardly from an outer surface of the first component.

A brush assembly has a brush holder rotatable about a rotation axis, a ring brush carried on the holder and having an annular array of radially outwardly projecting bristles, and a stop element fixed adjacent the ring brush, of noncircular section. This stop element extends along and is rotatable about a longitudinal axis generally parallel to the rotation axis and projects into the array of bristles.
