Abstract

electrical toothbrush with a plurality of movable bristle segments, characterized that the attachment head of two or more consecutive Bristle segments consists.

Description

Today's common, electric toothbrushes consist of two parts. A handpiece / handle ( 1 , Part A) with battery and a replaceable, attachable toothbrush attachment ( 1 , Part B) at its upper end, or head are the bristles. Today's models have either a solid, one-piece toothbrush attachment or a two- or multi-part attachment consisting of the shaft ( 1 , Part C) and one or more movable, mostly rotating segment (s) with bristles ( 1 , Part D) at the top.

Dentists recommend when brushing one Movement from the edge of the gum to the gingival margin, ie from the top to the bottom down in even movements. The by the usual today Toothbrushes arising movement has on the models with a fixed attachment Although such a vertical movement, but the effect radius is through the one-piece, on the brush axis fixed essay very limited. You also have to work with the hand of the and ab movement from gum line to gum line follow to the complete dentition, optimally including gum insertion, to reach with the bristles. For the models with two or more parts, or round attachment head creates a circular, rotating movement, the dental technically is not optimal. There is still there numerous hybrids or variants with more or less low Modifications of the o. G. Cleaning principles.

The here present invention works according to another principle.

The toothbrush is also, as is usual today, battery-operated, and the handle or the handpiece ( 2 , Part E) corresponds to today's models in terms of size, ergonomics and electrical issues. The toothbrush attachment ( 2 , Part F) is interchangeable and consists, as in current models, of a shaft ( 2 , Part G) with a movable head ( 2 , Part H).

The top hat here, however, is longer, possibly larger and consists of several consecutively arranged bristle segments ( 3 , Part I) that can reciprocate and / or move independently and / or individually on their axis back and forth. These individual bristle segments can be mounted centrally or also up and down, or right and left, offset to the toothbrush axis. When the toothbrush is in a horizontal position, part of the segments may move upwards from a previously defined zero position and the other part downwards. It would also be possible for all segments to be able to move upwards and downwards, one after the other, alternately or otherwise coordinated with one another. ( 4 , Part a-d)

By the segmentation and a predefined sequence of movements of these individual segments is, with appropriate length of Segments and bristles, a larger radius as with conventional Achieved models. Follow the up and down movement with the Hand is no longer, or only minimal, necessary.

The transfer of kinetic energy (from the battery) on the tower head and on the individual bristle segments works, as with the conventional Models, about an integrated into the essay, or attachment shaft mechanism. This here described toothbrush attachment is, as well as the usual today Models, for designed a repeated use and then can after wear be thrown away.

The toothbrush can also Play music.

The toothbrush can also be purely mechanical, with a hand-operated elevator mechanism.

Of the in protection claim 1-7 The invention is based on the idea to use a toothbrush on the one hand construct an optimal one for dental health, vertical movement, from the edge of the gum to the edge of the gum, and on the other hand saves time and energy because less vertical Hand movements are required. In addition, she should, for example, for children entertaining, that's why the music.

Claims (7)

Electric toothbrush with a plurality of movable bristle segments, characterized in that the attachment head consists of two or more consecutive bristle segments. toothbrush according to claim 1, characterized in that the individual Bristle segments up and down or right and left can move. toothbrush according to one of the preceding claims, characterized that the individual bristle segments in opposite directions and / or alternately and / or independently and / or timed to move on your axis. Toothbrush according to one of the preceding claims, characterized in that the individual bristle segments in a different kind and To move harmoniously on your axis. toothbrush according to one of the preceding claims, characterized that the individual bristle segments center, or alternately after above and below, or alternately to the right and left, or in otherwise offset to the axis center are attached. toothbrush according to one of the preceding claims, characterized that the toothbrush Can play music. toothbrush according to one of the preceding claims, characterized that they also operated without a battery, so purely mechanical, with a manual wind mechanism, can be.
