The transmission according to the invention for an electric toothbrush serves for the transmission and reforming of a rotational movement provided by an electric motor into a particularly careful and effective cleaning movement of a cleaning element. The ratio of the distance between the longitudinal mid-axis of an output shaft and the longitudinal mid-axis of a drive shaft of the transmission and of the distance between the longitudinal mid-axis of a shaft driving a cam of the transmission and the longitudinal mid-axis of the cam amounts to at least 10:1.

Electric toothbrush, and transmission for an electric toothbrush

An oral care implement including a head, a gum massaging element extending from proximate a peripheral side of the head, and a plurality of tooth cleaning elements positioned on the head. The plurality of tooth cleaning elements including a side tooth cleaning element positioned inwards and adjacent the gum massaging element. The gum massaging element provides transverse support to the side tooth cleaning element during brushing.

Oral care implement

An oral care implement has a head and a first tooth cleaning element. The first tooth cleaning element has a generally convex end surface such that dentifrice applied to the head is adapted to be directed towards a distal cleaning surface of the head. The oral care implement can also include a gum massaging element extending from a peripheral side of the head.

A toothbrush has a removable end cap at its free end area directed away from the bristles, which end cap closes off an inner space of a grip element. The end cap accommodates an electrical control element, in particular a potentiometer, which can be adjusted via an adjustment element arranged rotatably on the end cap. The toothbrush also comprises an electrical power consumption unit, in particular an electric motor, which is designed to set the bristles in vibration. The energy supply from an energy reservoir arranged in the interior to the electrical power consumption unit can be adjusted continuously by means of the control element, as a result of which the vibration intensity of the bristles can be steplessly adjusted.

An oral care implement having an turbine-like arrangement of cleaning elements. In one aspect, the invention is an oral care implement comprising a handle: a head connected to the handle, the head comprising a first surface, the first surface comprising an elliptical zone and a plurality of circumferentially spaced apart spirals spreading out from the elliptical zone; and for each spiral, an arcuate cleaning element wall extending outward from the first surface of the head along the spiral. In another aspect, the invention may be an apparatus for incorporation into an ansate oral care implement that utilizes the aforementioned arrangement of cleaning elements.

The inventive handle for a brush, in particular for a toothbrush or a domestic brush, has an integral handle body with a hollow space which is surrounded by a wall. Recesses which are offset in relation to one another and open into the hollow space are formed in the wall. The handle is produced from a plastic in an injection-molding process using an injection-molding die which has finger elements, with sections of these finger elements touching in a sealing manner when the injection-molding die is in the closed state and, as a result, these finger elements forming the recesses and the hollow space in the hardened handle.

An oral care implement with a handle includes a head with a tissue cleanser. The tissue cleanser may be a pad composed of an elastomeric material. The pad is disposed on the head on a surface opposite the tooth cleaning elements. The tissue cleanser may include a plurality of nubs extending for cleaning between the papillae of the tongue. The tissue cleanser may include a plurality of conically shaped nubs. A tissue cleanser can be used to reduce oral malodor problems and remove oral epithelial cells.

The toothbrush body according to the invention has on its top side a hand-supporting section with at least one longitudinal support strip which extends along the longitudinal axis of a handle part and next to which is located at least one recess which extends laterally from the top side to a bottom side. The recesses can take the form of holes located between two longitudinal support strips or of open lateral recesses formed in the broad sides of the toothbrush body.
