Oral cleaning tool for an oral hygiene device
First Claim
1. An oral cleaning tool for an electric oral hygiene device, comprising:
- a housing having a head section with a head cavity for accommodating a movable oral cleaning head and a neck section with a neck cavity and a handle coupling section;
a first magnetic coupling element including at least a permanent magnet or a magnetizable element being provided in the neck section for mechanical handle drive shaft connection by magnetic interaction;
wherein the first magnetic coupling element is mounted at a motion transmitter, the motion transmitter extending inside the neck cavity to the head cavity, the motion transmitter arranged so as to be movable in a linear or longitudinal direction, and wherein the motion transmitter is coupled with the oral cleaning head, such that during operation, the linear reciprocation is transmitted to the oral cleaning head, andwherein the first magnetic coupling element has a protective cover that covers at least a coupling side of the first magnetic coupling element that is arranged for establishing a magnetic connection and wherein the protective cover is a cup that is mounted by gluing, press-fitting, crimping, shrink-fitting, welding, or snapping or any combination thereof.

Abstract
An oral cleaning tool for an electric oral hygiene device is disclosed. The oral cleaning tool includes a housing having a head section with a head cavity for accommodating a movable oral cleaning head and a neck section with a neck cavity and a handle coupling section; a first magnetic coupling element including at least a permanent magnet or a magnetizable element being provided in the neck section for mechanical handle drive shaft connection by magnetic interaction. The first magnetic coupling element is mounted at a motion transmitter, the motion transmitter extending inside the neck cavity to the head cavity, the motion transmitter arranged so as to be movable in a linear or longitudinal direction. The motion transmitter is coupled with the oral cleaning head, the oral cleaning head arranged so as to oscillate in a rotational direction.
