Problems solved by technology

On the other hand, such split bristle tufts known hitherto are not very favorable in terms of plaque removal or interproximal cleaning
[0003] However, and above all, such fanned-out bristle tufts are relatively complex to manufacture

Embodiment Construction

[0071] figure 1 The toothbrush 1 shown comprises a handle 2 and a head 4 adapted to be connected thereto. More precisely, the brush head 4 is adapted to be connected to the neck 3 of the toothbrush 1 connected to the handle 2, said neck being configured in the form of a hollow toothbrush tube. However, it is also possible for the brush head 4 to comprise said neck 3 or at least a part thereof, and to be adapted to be connected to the handle 2 therewith.

[0072] The handle 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 .

[0073] In the embodiment shown, the rotational movement of the motor 5 is converted by the transmission 22 into an oscillating rotational movement of the transmission shaft 23 , which extends through the neck 3 to the brush head 4 . The toothbrush 1 can be activated and deactivated with a switch 24 mounted on the handle 2 .

Abstract

The polyamide plastic monofilament bristle fixed on a bristle head (4), has a cloverleaf-shaped bristle structure (10) having several longitudinal ribs arranged in a star shape or circumferentially, and projecting laterally from a core of the bristle structure. The bristle structure is configured to be self-fanning by the action of cleaning forces. Independent claims are included for the following: (1) brush head; and (2) electric toothbrush.

Description

technical field [0001] The invention relates to a bristle for a toothbrush, said bristle consisting of plastic monofilaments, wherein the preferably cloverleaf-shaped bristle body has several longitudinal ribs arranged in a star shape, the longitudinal ribs extending from the core of the bristle body Prominent laterally. Furthermore, the invention relates to a brush head for an electric toothbrush and an electric toothbrush having such a brush head, which has at least one bristle tuft comprising at least one such bristle. Background technique [0002] EP 11 13 737 B1 or US 6,871,373 B2 disclose bristles for toothbrushes having a substantially cloverleaf-shaped cross-section. The bristles are fanned out over a certain length of the free end such that the longitudinal ribs forming the bristle body of the cloverleaf-shaped cross-section individually protrude at the bristle ends and collectively form the flower-shaped bristle ends. Such split bristle ends provide a number of d...
