BROSSE A DENTS A MOT;Ux ELECTRIQUE L' invention est relative a une brosse a dents a moteur electrique. L'efficacite du brossage des dents depend du mouvement impart) par l'utilisateur a la brosse. Ce mouvement est souvent insuffisant pour assurer un brossage correct. C' est pourquoi il est couramment recommande d'utiliser une brosse a dents a moteur electrique. Les brosses a dents connues de ce type comportent un corps contenant un moteur et une partie anterieure se terminant par un element de brossage tournant autour d'un axe perpendiculaire a l'axe de rotation du moteur, les polls de The invention relates to a toothbrush with an electric motor. The effectiveness of toothbrushing depends on the movement imparted by the user to the brush. This movement is often insufficient to ensure correct brushing. This is why it is commonly recommended to use a toothbrush with an electric motor. Known toothbrushes of this type comprise a body containing a motor and an anterior part ending in a brushing element rotating about an axis perpendicular to the axis of rotation of the motor, the polls of
['element de brossage etant parallele a son axe de rotation. ['brushing element being parallel to its axis of rotation.
Lorsque lt clement de brossage tourne, les extremites des polls effectuent un mouvement circulaire sur la dent. Ce mouvement When the brushing element rotates, the ends of the polls make a circular movement on the tooth. This movement
peut aussi etre alternatif.can also be an alternative.
Mais le mouvement de cet element de brossage nt assure pas un nettoyage optimal des dents car on salt que le brossage le plus efficace est celui qui est effectue verticalement, ctest-a-dire selon l'axe de la dent. En outre, du fait de sa perpendicularite entre l'axe du moteur et l'axe de ['element de brossage, la brosse presente une forme coudee et est done souvent encombrante et d'une realisation onereuse en raison de la presence d'un organe transformant le mouvement de rotation de l'arbre du moteur en un mouvement de rotation selon un axe perpendiculaire. L' invention a pour but de remedier a au moins certains des inconvenients mentionnes ci-dessus. La brosse a dents entralnee par moteur electrique conforme a l' invention est caracterisee en ce qutelle comporte un element de brossage dont les polls ont une direction sensiblement radiale par rapport a son axe de rotation. De preference, l'axe de rotation de l' clement de brossage est But the movement of this brushing element does not ensure optimal cleaning of the teeth because it is known that the most effective brushing is that which is carried out vertically, that is to say along the axis of the tooth. In addition, due to its perpendicularity between the axis of the motor and the axis of the brushing element, the brush has a bent shape and is therefore often bulky and of an expensive construction due to the presence of a organ transforming the rotational movement of the motor shaft into a rotational movement along a perpendicular axis. The object of the invention is to remedy at least some of the drawbacks mentioned above. The toothbrush driven by an electric motor according to the invention is characterized in that it comprises a brushing element the polls of which have a direction substantially radial with respect to its axis of rotation. Preferably, the axis of rotation of the brushing element is
sensiblement parallele a la direction de la poignee. substantially parallel to the direction of the handle.
Dans ces conditions, quand la poignee est maintenue horizontalement, ce qui constitue la position habituellement utilisee pour le brossage, les polls de l' clement de brossage defilent verticalement contre la dent. Ainsi, l'utilisateur peut, sans effort et sans entra1nement, obtenir un brossage efficace puisque ce dernier s'effectue dans la direction optimale en maintenant la poignee dans la position la plus naturelle. De preference, la zone arriere de lielement de brossage est entouree par un capot pour que cet element tournant Under these conditions, when the handle is held horizontally, which is the position usually used for brushing, the polls of the brushing element scroll vertically against the tooth. Thus, the user can, without effort and without entrainment, obtain an effective brushing since the latter is carried out in the optimal direction while maintaining the handle in the most natural position. Preferably, the rear area of the brushing element is surrounded by a cover so that this rotating element
ne vienne pas en contact avec la partie interne de la joue. do not come into contact with the inner part of the cheek.
Dans une realisation, l' clement de brossage est In one embodiment, the brushing element is
entralne en rotation de facon continue par un moteur electrique. rotated continuously by an electric motor.
Dans une autre realisation, on prevoit entre le moteur electrique et l' clement de brossage des moyens pour conferer un mouvement de rotation alternativement dans un sens et dans l'autre. L' invention concerne, de facon generale, un element de brossage de dents pour brosse a dents electrique, cet element etant rotatif, qui est caracterise en ce que les polls ont une direction sensiblement radiale par rapport a l'axe de rotation In another embodiment, means are provided between the electric motor and the brushing element for imparting a rotational movement alternately in one direction and in the other. The invention relates, in general, to a toothbrushing element for an electric toothbrush, said element being rotary, which is characterized in that the polls have a substantially radial direction relative to the axis of rotation.
de l' clement.of the clement.
Wile concerne aussi une brosse a dents electrique comportant un tel element de brossage et un moteur electrique i loge dans une poignee, l'axe de rotation de l' clement de Wile also relates to an electric toothbrush comprising such a brushing element and an electric motor housed in a handle, the axis of rotation of the clement of
brossage etant sensiblement parallele a l'axe de la poignee. brushing being substantially parallel to the axis of the handle.
Selon une realisation, l'axe de rotation de l' clement de brossage est sensiblement parallele a l'axe de rotation du moteur electrique. La brosse a dents peut comporter deux parties separables l'une de l'autre, a savoir une partie de poignee logeant le moteur electrique et une partie avant comprenant According to one embodiment, the axis of rotation of the brushing element is substantially parallel to the axis of rotation of the electric motor. The toothbrush may have two parts that can be separated from each other, namely a handle part housing the electric motor and a front part comprising
l' clement de brossage.the brushing element.
De preference, la brosse a dents comporte un capot entourant une partie de l' clement de brossage. Ce capot peut Preferably, the toothbrush has a cover surrounding part of the brushing element. This hood can
presenter des formes arrondies.present rounded shapes.
L' element de brossage est par exemple entralne en The brushing element is, for example,
rotation selon un mouvement continu. rotation in a continuous movement.
En variante, la brosse a dents comporte des moyens pour que l 'clement de brossage tourne alternativement dans un sens et dans l'autre. Par exemple, lt clement de brossage est solidaire d'une lumiere, cette lumiere recevant un ergot a distance de l'axe de rotation d'un arbre entra1ne par le moteur As a variant, the toothbrush includes means for the brushing element to rotate alternately in one direction and in the other. For example, the brushing element is integral with a light, this light receiving a lug at a distance from the axis of rotation of a shaft driven by the motor

D'autres caracteristiques et avantages de l' invention Other characteristics and advantages of the invention
apparaltront avec la description de certains de ses modes de will appear with the description of some of its modes of
realisation, celle-ci etant effectuee en se referent aux dessins ciannexes sur lesquels: la figure 1 est une vue d' ensemble d'une brosse a dents conforme a l' invention, la figure 2 est une vue partiellement en coupe de la partie avant de la brosse representee sur la figure 1, la figure 3 est une vue d'une extremite de la brosse representee sur la figure 1, la figure 4 est une coupe selon la ligne 4-4 de la figure 1, et la figure 5 illustre l'utilisation de la brosse embodiment, this being carried out with reference to the attached drawings in which: FIG. 1 is an overall view of a toothbrush according to the invention, FIG. 2 is a partially sectional view of the front part of the brush shown in Figure 1, Figure 3 is a view of one end of the brush shown in Figure 1, Figure 4 is a section along line 4-4 of Figure 1, and Figure 5 illustrates l using the brush
representee sur les figures 1 a 4.shown in Figures 1 to 4.
i La brosse a dents representee sur la figure 1 comporte une poignee 10, logeant un moteur electrique (non montre) dont i The toothbrush shown in FIG. 1 includes a handle 10, housing an electric motor (not shown),
l'axe de rotation est parallele a l'axe 12 de la poignee. the axis of rotation is parallel to the axis 12 of the handle.
Cette brosse comporte aussi une partie anterieure 14, amovible de la partie 10 de poignee, se terminant par un element de brossage 16 presentant un axe de rotation 18 parallele a l'axe 12. Les polls de ['element de brossage sont, selon une disposition importante de l' invention, perpendiculaires ou This brush also includes an anterior portion 14, removable from the handle portion 10, ending in a brushing element 16 having an axis of rotation 18 parallel to the axis 12. The polls of the brushing element are, according to a important arrangement of the invention, perpendicular or
sensiblement perpendiculaires a l'axe 18. substantially perpendicular to axis 18.
L'amovibilite de la partie avant 14 par rapport a la poignee 10 permet a l'utilisateur de disposer de plusieurs elements de brossage, par exemple pour pouvoir utiliser des elements de souplesses ou duretes differentes ou pour que le meme dispositif puisse etre utilise par plusieurs personnel, la The removability of the front part 14 relative to the handle 10 allows the user to have several brushing elements, for example to be able to use elements of different softnesses or hardnesses or so that the same device can be used by several staff, the
poignee avec son moteur etant commune. handle with its motor being common.
L'axe de rotation 18 de l' clement 16 etant parallele a l'axe de la poignee, il n'est pas necessaire de prevoir de renvoi angulaire comme dans les brosses precedemment connues et, en outre, la brosse presente une forme generale allongee avec un encombrement reduit et son aspect est tres similaire a celui The axis of rotation 18 of the element 16 being parallel to the axis of the handle, it is not necessary to provide angular reference as in the previously known brushes and, moreover, the brush has a generally elongated shape with a reduced bulk and its appearance is very similar to that
d'une brosse ordinaire.an ordinary brush.
De plus, l'utilisation de la brosse est tres simple et efficace. En effet, comme montre sur la figure 5, quand la brosse est maintenue horizontalement, l'axe de rotation 18 de l' clement 16 est egalement horizontal et les extremites 20 des polls 21 de cet element 16 defilent verticalement contre la In addition, the use of the brush is very simple and effective. Indeed, as shown in Figure 5, when the brush is held horizontally, the axis of rotation 18 of the element 16 is also horizontal and the ends 20 of the polls 21 of this element 16 scroll vertically against the
surface de la dent 22 en cours de brossage. surface of tooth 22 during brushing.
Pour separer la partie avant 14 de la poignee 10 il suffit de la firer et, pour associer la partie avant 14 a la poignee 10, on introduit un embout 44 de la partie avant 14, a l 'oppose de l' clement 16, dans une ouverture correspondante de la poignee et la position correcte est obtenue par cooperation To separate the front part 14 of the handle 10, it suffices to twist it and, to associate the front part 14 to the handle 10, a tip 44 of the front part 14, opposite the element 16, is introduced in a corresponding opening of the handle and the correct position is obtained by cooperation
d'une nervure 46 avec une encoche correspondante de la poignee. a rib 46 with a corresponding notch in the handle.
Dans l'exemple, la rotation s'effectue de facon alternative dans un sens et dans l'autre. A cet effet, du corps de l' clement 16 est solidaire une lumiere 24 (figure 4) et cette lumiere recoit un ergot 26 se trouvant a l'extremite d'un bras 28 solidaire d'un arbre 30 entralne par le moteur. Le bras 28 In the example, the rotation is performed alternately in one direction and in the other. To this end, the body of the element 16 is secured to a light 24 (FIG. 4) and this light receives a lug 26 located at the end of an arm 28 secured to a shaft 30 driven in by the motor. The arm 28
est perpendiculaire a l'arbre 30.is perpendicular to the tree 30.
Quand l'arbre 30 tourne autour de son axe 32, la cooperation de l' ergot 26 avec la lumiere 24 provoque ltoscillation de cette lumiere entre deux positions, 241 et 242 (figure 4), et, ainsi, l' oscillation de l' clement de brossage 16 When the shaft 30 rotates about its axis 32, the cooperation of the lug 26 with the light 24 causes the oscillation of this light between two positions, 241 and 242 (FIG. 4), and, thus, the oscillation of the brushing clement 16
autour de son axe 18.around its axis 18.
La partie avant 14 de la brosse a dents electrique comporte un capot 34 qui empeche le contact entre la partie arriere 36 de l' clement 16 avec la zone interne de la goue. Ce capot 34 presente des formes arrondies pour eviter de blesser l'utilisateur. Dans l'exemple, pour la mise en route et l'arret du moteur electrique, on prevoit un interrupteur de type "Reed" dont l'ouverture et la fermeture est commandee par un aimant 40 (figure 1) solidaire d'un contacteur glissant 42. Pour la mise en route du moteur on fait glisser le contacteur 42 et l'aimant 40 se place en face de contacts pour les attirer l'un vers l'autre. L'alimentation en energie electrique steffectue grace a des piles logees a l'interieur de la poignee 10 et/ou par The front part 14 of the electric toothbrush has a cover 34 which prevents contact between the rear part 36 of the element 16 and the internal zone of the groove. This cover 34 has rounded shapes to avoid injuring the user. In the example, for starting and stopping the electric motor, a "Reed" type switch is provided, the opening and closing of which is controlled by a magnet 40 (FIG. 1) secured to a sliding contactor 42. To start the engine, the contactor 42 is slid and the magnet 40 is placed in front of contacts to attract them towards each other. The electrical energy supply is effected by means of batteries housed inside the handle 10 and / or by
l'intermediaire du secteur.the intermediary of the sector.
