Problems solved by technology

While such extended tufts on the outer circumference of the bristled portion do allow enhanced cleaning of the interproximal space, the cleaning effect on the portion of the tooth surface adjoining the interproximal space is not yet ideal
On the other hand, such a configuration of the bristled part cannot really move gently from tooth to tooth, so the brushing movement of the toothbrush head in the longitudinal direction of the toothbrush produces a jab

Embodiment Construction

[0085] figure 1 The illustrated exemplary electric toothbrush 1 includes a handle portion 2 and a toothbrush head 4 adapted to be detachably coupled thereto. The toothbrush head 4 comprises a neck part 3 of the toothbrush 1 connected to the handle part 2, said neck part 3 being configured in the form of a partially hollow tube.

[0086] The handle portion 2 houses in its interior an energy source 20 , preferably in the form of a rechargeable battery, a motor 5 , preferably in the form of an electric motor, and a control device 21 .

[0087] In the embodiment shown, the rotational motion of the motor 5 is converted by the transmission 22 into an oscillating rotational motion of a drive shaft 23 extending through the neck portion 3 to the distal end of the toothbrush head 4 . The toothbrush 1 can be activated and deactivated with a switch 24 mounted on the handle part 2 .

[0088] At the end of the transmission shaft 23, the bristle carrier 7 can be driven in an oscillating ro...

Abstract

The invention is directed to an electric toothbrush and a drivable brush head therefore having a bristle support including mounting means for the movable mounting of the bristle support as well as a plurality of bristle tufts arranged on the bristle support. A central area of said bristle support comprises at least one bristled section that consists of two centre bristle tufts having a cross- section larger than the cross-section of middle bristle tufts adjoining the central area, the centre bristle tufts each having an elongated, in particular half-moon shaped, banana-shaped or kidney- shaped form that complement each other so that the bristled section of the central area has an approximately circular, oval or elliptical structure. The plurality of bristle tufts may be provided in several nesting rings or regions, where on an outer ring outer bristle tufts of an elongated tuft cross-section are mounted, and on a middle ring the middle bristle tufts are mounted that each of a cross-section smaller than the cross-section of the elongated bristle tufts of the outer ring. The centre bristle tufts in accordance with the invention provide a high stability of the central bristled area so that the centre bristle tufts can withhold forces pushing the tufts against the teeth without easily bending away under this pushing force.

Description

technical field [0001] The invention relates to an electric toothbrush and a drivable toothbrush head for an electric toothbrush, the toothbrush head having a bristle support and a plurality of bristle tufts arranged on the bristle support, the bristle support Mounting parts for movably mounting the bristle support are included. Background technique [0002] With drivable bristled parts, it is often difficult to obtain high bristle densities on the bristle support, especially when it is desired to secure the bristle tufts to the bristle support using a technique known as anchor tufting. On the one hand, the drivable bristle supports of electric toothbrushes have a relatively small surface area for focusing the drive motion on the tooth surface, especially when the drive performs an oscillating rotational motion. On the other hand, it is desirable to have a specialized tuft configuration on the actuatable bristled portion. For example, circular bristle supports that oscilla...
