Abstract
Description
Brosse à dents rotative Electriquet
L'invention concerne une brosse à dents électrique.Electriquet rotary toothbrush
The invention relates to an electric toothbrush.
Les brosses à dents électriques sont connues depuis longtemps. Elles comportent un manche creux dans lequel sont logés un moteur électrique et un dispositif d'alimentation électrique, ou de piles. L'arbre du moteur est relié par un dispositif mécanique à un support de brosse à dents auquel il imprime, grâce au dispositif mécanique, un mouvement angulaire alternatif ou hélicoldal. Sur le support de brosse à dents peut être emmanchée la tige d'une brosse à dents dont les soies sont arrangées de manière classique d'un seul côté de l'extrémité libre de la tige. Electric toothbrushes have been known for a long time. They include a hollow handle in which an electric motor and a power supply device, or batteries, are housed. The motor shaft is connected by a mechanical device to a toothbrush support to which it prints, thanks to the mechanical device, an alternating or helical angular movement. On the toothbrush holder can be fitted the rod of a toothbrush, the bristles of which are conventionally arranged on one side of the free end of the rod.
Grâce à une telle brosse électrique, on peut en la promenant sur les mâchoires, brosser les dents dans le sens vertical ce qui permet un bon nettoyage des espaces interdentaires.Thanks to such an electric brush, it is possible by walking it over the jaws, to brush the teeth in the vertical direction which allows a good cleaning of the interdental spaces.
Toutefois, de telles brosses ont pour inconvénient principal que les dents, si elles sont bien brossées verticalement, le sont dans les deux sens, c'est-à-dire de haut en bas et de bas en haut. Or, si le brossage de la dent s'effectue favorablement dans le sens gencive-pointe, le brossage dans le sens pointe-gencive est néfaste à cette dernière et contraire aux recommandations du corps médical y compris aux recommandations de l'O.M.S.However, such brushes have the main disadvantage that the teeth, if they are well brushed vertically, are in both directions, that is to say from top to bottom and from bottom to top. However, if the brushing of the tooth is done favorably in the gum-tip direction, brushing in the tip-gum direction is harmful to the latter and contrary to the recommendations of the medical profession including the recommendations of the O.M.S.
L'invention vise à pallier ces inconvénients en procurant un dispositif simple qui permet un brossage des dents, toujours dans le même sens, de la gencive vers la pointe et protège la paroi interne de la joue contre le frottement permanent de la brosse. The invention aims to overcome these drawbacks by providing a simple device which allows brushing of the teeth, always in the same direction, from the gum to the tip and protects the inner wall of the cheek against the permanent friction of the brush.
Selon l'invention, la brosse à dents électrique comporte une brosse à dents proprement dite, constituée par une tige à l'une des extrémités de laquelle les soies sont disposées sur toute la périphérie de la tige à la manière d'un écouvillon. L'autre extrémité de la tige est emmanchée dans un support monté sur le boîtier et en liaison directe, ou par l'intermédiaire d'un réducteur, avec l'arbre du moteur électrique, de façon à tourner avec lui. According to the invention, the electric toothbrush comprises a toothbrush proper, constituted by a rod at one end of which the bristles are arranged over the entire periphery of the rod in the manner of a swab. The other end of the rod is fitted into a support mounted on the housing and in direct connection, or via a reduction gear, with the shaft of the electric motor, so as to rotate with it.
Du côté de la brosse, le boîtier est prolongé jusqu'à l'extrémité de celle-ci d'un cache de protection ayant une surface interne cylindrique de diamètre légèrement supérieur à celui de la brosseen forme d'écouvillon et couvrant celle-ci sur un arc de 90" à 1800. Grâce à ce cache de protection, la paroi interne de la joue n'est pas soumise au frottement de la brosse à dents. On the side of the brush, the housing is extended to the end of the latter by a protective cover having a cylindrical internal surface of diameter slightly greater than that of the brush in the form of a swab and covering it on an arc from 90 "to 1800. Thanks to this protective cover, the internal wall of the cheek is not subjected to the friction of the toothbrush.
L'invention sera maintenant exposée plus en détails au moyen d'un exemple limitatif de réalisation représenté au dessin annexé sur lequel
La figure 1 est une vue en coupe partielle d'une brosse à dents électrique selon l'invention ;
La figure 2 est une vue de l'extrémité de la brosse à dents avec son cache de protection.The invention will now be explained in more detail by means of a limiting example of embodiment shown in the appended drawing in which
Figure 1 is a partial sectional view of an electric toothbrush according to the invention;
Figure 2 is a view of the end of the toothbrush with its protective cover.
La brosse à dents électrique comporte un boîtier 1 de forme générale cylindrique dont une partie 2 servant de manche contient les piles d'alimentation du moteur
Dans la partie- 3 du boîtier située au bout du manche 2 est disposé un moteur, non représenté, dont le sens de rotation et l'arrêt sont commandés par un interrupteur à trois positions 4. La partie 3 du boîtier est prolongée par un cache 5 moulé d'une seule pièce avec elle, ou rapporté, et formant une paroi cylindrique sur environ 1500. Une brosse à dents 6, interchangeable est emmanchée sur un support de brosse, non représenté, entraîné directement par l'arbre du moteur. Elle est constituée d'une tige 7 dont l'extrémité 8 est pourvue de soies sur toute- sa périphérie. L'axe de rotation de la brosse 6 correspond à l'axe de la surface cylindrique du cache 5.The electric toothbrush comprises a box 1 of generally cylindrical shape of which a part 2 serving as a handle contains the power supply batteries of the motor.
In the part 3 of the housing located at the end of the handle 2 is arranged a motor, not shown, whose direction of rotation and stopping are controlled by a three-position switch 4. Part 3 of the housing is extended by a cover 5 molded in one piece with it, or attached, and forming a cylindrical wall of about 1500. A toothbrush 6, interchangeable is fitted on a brush holder, not shown, driven directly by the motor shaft. It consists of a rod 7, the end 8 of which is provided with bristles over its entire periphery. The axis of rotation of the brush 6 corresponds to the axis of the cylindrical surface of the cover 5.
Sur la figure 2, on a représenté l'extrémité du cache 5 qui se termine par un bord radial couvrant les soies de la brosse sur environ 1500. In Figure 2, there is shown the end of the cover 5 which ends with a radial edge covering the bristles of the brush on about 1500.
La brosse électrique fonctionne comme suit
L'utilisateur amène l'interrupteur 4 sur une des deux positions de marche du moteur. La brosse 6 va tourner dans un sens qui va lui permettre de brosser, de la gencive vers la pointe, les dents situées d'un côté du maxillaire supérieur ou inférieur et devant, puis, en changeant de main et en amenant l'interrupteur sur l'autre position, celles de l'autre côté. Avec les mêmes opérations, l'utilisateur brossera ses dents de l'autre maxillaire i il fera de même pour la partie intérieure des dents.The electric brush works as follows
The user brings the switch 4 to one of the two engine operating positions. Brush 6 will rotate in a direction which will allow it to brush, from the gum towards the tip, the teeth located on one side of the upper or lower jaw and in front, then, changing hands and bringing the switch to the other position, those on the other side. With the same operations, the user will brush his teeth from the other maxilla i he will do the same for the inner part of the teeth.
Grâce au cache 5, les soies 8 de la brosse 6 ne touchent pas la paroi interne de la joue. Thanks to the cover 5, the bristles 8 of the brush 6 do not touch the inner wall of the cheek.
Il va de soi que l'on peut apporter à l'exemple décrit toute modification utile sans sortir du cadre de l'invention. Par exemple, la brosse peut être pourvue d'un dispositif de branchement sur le secteur au lieu de piles. It goes without saying that any useful modification can be made to the example described without departing from the scope of the invention. For example, the brush may be provided with a device for connection to the mains instead of batteries.
