Abstract:
A brush head for an electric toothbrush is disclosed. The brush head includes a plate-shaped bristle support including mounting means for the movable mounting of the bristle support, the bristle support carrying at least two outer bristle tufts and at least two inner bristle tufts, the outer bristle tufts having a greater height than the inner bristle tufts, such that in the working surface defined by the free ends of the tufts there is formed a central depression which has a groove-shaped concave bottom curved in one direction and extending substantially straight in the direction vertical thereto. At least one of the outer bristle tufts has a chamfer on its outer lying edge of its free end close to the circumferential side of the bristle support.
Abstract:
A brush head for an electric toothbrush is disclosed. The brush head includes a substantially plate-shaped bristle support carrying a bristle field, the bristle field having a main axis extending substantially perpendicularly to the bristle support and including a plurality of bristles defining with their free ends a flat or concave working surface to be put onto the teeth to be cleaned; driving and/or transmitting means for driving the bristle support using a reciprocating poking motion along a poking axis and an oscillatory rotational motion about an axis of rotation; and connecting means for connecting the bristle support with a toothbrush handpiece such that a brush head longitudinal axis extends substantially parallel to a toothbrush handpiece longitudinal axis in connected condition. The bristle field with its bristle field main axis is arranged at a tilt relative to the brush head longitudinal axis such that the bristle field main axis is inclined at an acute angle of inclination (Φ) to a perpendicular upon the brush head longitudinal axis, and wherein a working surface is inclined in opposite direction to the tilt of the bristle field main axis such that a plane lying onto the working surface is sloped at an acute angle to a plane perpendicular to the bristle field main axis.
Abstract:
A brush head for an electric toothbrush is disclosed. The brush head includes a bristle support having mounting means for the movable mounting of the bristle support and a plurality of bristle tufts arranged on the bristle support in at least one outer ring and one middle ring, the middle ring being nested within the outer ring and having a central area. The outer ring includes outer bristle tufts having an elongated tuft cross-section, which outer bristle tufts are mounted on opposing sides of the outer ring. The middle ring includes at least two middle bristle tufts that each have a cross-section that is smaller than the cross-section of the outer bristle tufts and a central area including at least one bristled section that consists of two center bristle tufts having a cross-section larger than the cross-section of the middle bristle tufts. The center bristle tufts each having an elongated, substantially kidney-shaped form that complement each other so that the bristled section of the central area has an approximately circular, oval or elliptical structure.
Abstract:
An electric toothbrush is disclosed. The tootbrush includes two elements to be driven, wherein the first element is a movable brush head and the second element is a pump; an electric motor; and a device that drives the movable brush head in both directions of rotation of the electric motor and drives the pump in one direction of rotation.
Abstract:
A package for an electrical device that facilitates product demonstration is provided. The package includes a power source; a display device for displaying a rest mode, a normal mode or a presentation mode; and a transparent window for viewing the display device. The presentation mode includes emission of a user-specific optical and/or acoustic signal sequence by the display device and can be activated without manual impact onto the packaging.

Abstract:
The invention relates to a small electrical appliance, for example an electric toothbrush (1), with two elements to be driven and with an electric motor (10). The small electrical appliance has a device (16.1; 16.2; 16.3) that drives the first and/or the second element depending on the direction of rotation of the electric motor (10). The first element to be driven can be a movable brush head (2), and the second element to be driven can be a pump (7, 14) for conveying a care agent to the brush head (2) from a reservoir, wherein the device (16.1, 16.2, 16.3) drives the brush head (2) in both directions of rotation of the electric motor (10), but drives the pump (7, 14) only in one direction of rotation of the electric motor (10). If the electric toothbrush (1) has a brush head (2) and first and second reservoirs (6, 13) for two different care agents, the first reservoir (6) is connected via a first pump (7) to a first channel (8) and the second reservoir (13) is connected via a second pump (14) to a second channel (15), these channels opening into the brush head (2). The first and/or second pump (7, 14) can alternately be driven from the electric motor (10), by means of a device (16/1; 16.2; 16.3), depending on the direction of rotation of the electric motor (10).
