摘要:
An attachment section, in particular a brush section, suitable for connection to a handle section of an oral hygiene device is proposed. The attachment section has an attachment housing having a first coupling structure suitable for establishing a connection with a second coupling structure of the handle section, at least a functional element mounted at the attachment housing for driven movement, a motion transmitter extending in a cavity formed inside of the attachment housing, the motion transmitter being functionally connected on one end with the functional element, and a first magnetic coupling element arranged at another end of the motion transmitter, the first magnetic coupling element comprising at least a permanent magnet or a magnetizable element suitable for establishing a magnetic connection with a second magnetic coupling element provided in the handle section.

An attachment section, in particular a brush section, for connection, optionally for detachable connection, to a handle section (200) of an oral hygiene device, is proposed. The attachment section has a first magnetic coupling element (120) having at least a permanent magnet or a magnetizable element arranged for establishing a magnetic connection with a second magnetic coupling element (220) provided in the handle section (200) in an attached state. The attachment section further has an attachment housing (150) having a first coupling structure (152) for establishing a further connection with a second coupling structure of the handle section.

A personal care device has an electrically powered driving unit for driving a working implement of the personal care device at a desired speed and/or amplitude and/or frequency, and a control unit for controlling the driving unit in response to load onto the working implement to change speed and/or amplitude and/or frequency of the working implement upon a change in load applied thereto. The control unit includes a detector for detecting changes of an operating parameter of the driving unit, which operating value is responsive to load onto the working implement, and a powering unit for varying the electrical powering of the driving unit in response to a detected value of the operating parameter such that speed and/or amplitude and/or frequency of the working implement is changed from an idling value to an increased operation value.

The mouthpiece assembly includes a receptacle (12) for receiving teeth therein, with bristles (24) mounted thereon for contacting and cleaning the teeth. The receptacle and the bristles cover at least 4 cm. A drive train (20) drives the receptacle such that the bristles move substantially at right angles toward and away from the surfaces of the teeth, the drive train including a motor (22) which produces sufficient force to produce a minimum bristle tip threshold pressure of 6 Newtons per cm and a maximum of 85 Newtons per cm.

The power toothbrush includes a toothbrush body and a stem portion extending from the toothbrush body which has a workpiece with a flexible membrane at a remote end thereof, and a flexible membrane at a near end thereof as well. A movable piston is positioned in the stem portion, as well as a fluid which is in communication with the flexible membrane at the workpiece end of the toothbrush and the flexible membrane at the near end of the stem portion. The body includes a solenoid coil which, when actuated, moves the piston in opposing directions in a controlled manner within the stem, which acts on the fluid in the stem and moves the flexible membrane at the workpiece in and out at a desired frequency and amplitude.

The hands-free dental appliance includes upper and lower tray members (12, 14) for receiving the teeth of the user, the tray members having teeth contact members such as bristles. A power assembly (28) moves the tray member in a reciprocal manner, resulting in cleaning of the surfaces of the teeth by the bristles. A grounding system (30) with bite portions (32, 34, 36) for biting contact whereby the user's teeth grounds the appliance to the user's mouth structure, reacting both static and dynamic forces, the grounding system being either separate from the tray members or flexibly connected to the tray members, allowing the tray members to move and clean the teeth without the user having to hold or otherwise manipulate the appliance.
摘要:
A vibrating toothbrush comprising a handle including a body with a tubular member extending outwardly from one end. A replaceable sleeve slides over the tubular member and detachably engages the body. One or more of the sleeve, tubular member and body incorporates a vibration damping zone for reducing vibration transmission from the sleeve to the handle. The damping zone is one of a material that differs in damping properties to the material of the rest of the toothbrush; a hole defined in the one of the sleeve, tubular member and body, and a toothbrush where that hole is filled with an elastomeric material.
