Description

BROSSE DE NETTOYAGE DE DENTS AMOVIBLE POUR DISPOSITIF DE PULVERISATION REMOVABLE TOOTH CLEANING BRUSH FOR SPRAYING DEVICE
En matière d'hygiène dentaire, on connaît différentes techniques de nettoyage dentaire visant à éliminer la plaque dentaire qui pollue les dents.In dental hygiene, various dental cleaning techniques are known which aim to remove the dental plaque which pollutes the teeth.
Une technique largement utilisée par le grand public consiste à se brosser les dents avec une brosse à dents ordinaire ou électrique. Cependant, l'efficacité du brossage est loin d'être satisfaisante, de nombreux essais cliniques ayant montré que même un brossage soigneux n'enlevait guère que 60% de la plaque dentaire.A technique widely used by the general public is to brush your teeth with an ordinary or electric toothbrush. However, the effectiveness of brushing is far from satisfactory, numerous clinical trials have shown that even careful brushing only removes 60% of dental plaque.
Il existe également des dispositifs à jet d'eau qui nettoient les dents à l'aide d'un jet d'eau puisé continu, la plaque dentaire se décollant sous la frappe du jet d'eau contre les dents. L'inconvénient majeur du jet d'eau puisé est qu'il n'élimine la plaque dentaire que sur une surface restreinte d'impact du jet, les dents ne pouvant pas être balayées parfaitement par le jet.There are also water jet devices which clean the teeth using a continuous pulsed water jet, the dental plaque peeling off under the impact of the water jet against the teeth. The major drawback of the pulsed water jet is that it removes plaque only on a restricted surface of impact of the jet, the teeth cannot be swept perfectly by the jet.
Pour résoudre cet inconvénient, le document PCT/FR93/00974 enseigne un dispositif de pulvérisation comprenant une buse de pulvérisation reliée, avec interposition d'un mélangeur eau-air, à un compresseur d'air et à un réservoir d'eau. Sous forme de gouttelettes puisées, l'eau est pulvérisée par la buse et vient frapper les dents sur une surface d'impact bien plus étendue que celle d'un jet. La pulvérisation permet d'éliminer toute la plaque dentaire mais un tel résultat n'est obtenu qu'après une longue durée de pulvérisation, trop longue par rapport au temps que consacre généralement une personne pour se nettoyer les dents.To resolve this drawback, document PCT / FR93 / 00974 teaches a spraying device comprising a spraying nozzle connected, with the interposition of a water-air mixer, to an air compressor and to a water tank. In the form of pulsed droplets, water is sprayed by the nozzle and strikes the teeth on a much larger impact surface than that of a jet. Spraying makes it possible to remove all the dental plaque, but such a result is obtained only after a long duration of spraying, too long compared to the time that a person generally spends to clean his teeth.
L'invention propose de résoudre cet inconvénient.The invention proposes to overcome this drawback.
A cet effet, l'invention concerne une tête de nettoyage de dents amovible pour dispositif de pulvérisation, destiné au nettoyage de dents, comprenant une buse de pulvérisation, destinée à pulvériser un liquide de nettoyage, et des poils de brossage formant un gabarit pour positionner la buse de pulvérisation à une distance prédéterminée par rapport aux dents à nettoyer, la pulvérisation et le brossage étant destinés à agir de façon combinée pour nettoyer les dents.To this end, the invention relates to a removable tooth cleaning head for a spraying device, intended for cleaning teeth, comprising a spray nozzle, intended to spray a cleaning liquid, and brushing bristles forming a template for positioning. the spray nozzle at a predetermined distance from the teeth to be cleaned, the spraying and brushing being intended to act in combination to clean the teeth.
Les poils de brossage, qui servent de gabarit, permettent de positionner facilement et surtout correctement la buse de pulvérisation par rapport aux dents à nettoyer. Il en résulte une. action combinée de la pulvérisation et du brossage qui procure une meilleure efficacité du brossage. La plaque dentaire est ainsi éliminée totalement et rapidement.The brushes, which serve as a template, allow the spray nozzle to be positioned easily and above all correctly with respect to the teeth to be cleaned. This results in one. combined action of spraying and brushing which provides better brushing efficiency. Dental plaque is removed completely and quickly.
Avantageusement encore, la buse de pulvérisation s'étend en dehors de la zone d'implantation des poils de brossage.Advantageously also, the spray nozzle extends outside the implantation area of the brushing bristles.
L'invention sera mieux comprise à l'aide de la description suivante d'une forme de réalisation particulière de l'invention en référence au dessin annexé sur laquelle:The invention will be better understood with the aid of the following description of a particular embodiment of the invention with reference to the appended drawing in which:

- la figure 4 qui représente une vue de côté d'une douille à baïonnette de l'ensemble de la figure 1.- Figure 4 which shows a side view of a bayonet socket of the assembly of Figure 1.
La tête de nettoyage de dents de l'invention est destinée à être montée de façon amovible sur un dispositif de pulvérisation, du type enseigné par le document PCT/FR93/00974.The tooth cleaning head of the invention is intended to be removably mounted on a spraying device, of the type taught by document PCT / FR93 / 00974.
Comme décrit plus en détail dans le document cité ci-dessus, le dispositif de pulvérisation comporte, dans une base, un compresseur d'air et un réservoir de liquide de nettoyage et, dans un manche 2 de réception de la tête de nettoyage 1, creux et de forme générale cylindrique, un mélangeur air- liquide, non représenté, à deux entrées et une sortie.As described in more detail in the document cited above, the spraying device comprises, in a base, an air compressor and a reservoir of cleaning liquid and, in a handle 2 for receiving the cleaning head 1, hollow and generally cylindrical, an air-liquid mixer, not shown, with two inlets and one outlet.
Les deux entrées du mélangeur sont respectivement reliées au compresseur d'air et au réservoir de liquide de nettoyage par l'intermédiaire d'un conduit d'alimentation en air et d'un conduit d'alimentation en liquide. Les deux conduits d'alimentation du mélangeur sortent du manche 2 par l'une de ses extrémités 22. La sortie du mélangeur est ici reliée à une buse de raccord 23 par l'intermédiaire d'un conduit de pulvérisation 24. En outre, un autre conduit d'air relie un point du conduit d'alimentation en air du mélangeur, situé juste en amont de l'entrée du mélangeur, à un point du conduit de pulvérisation, situé juste en aval de la sortie du mélangeur. Une vanne est montée sur le conduit de liquide, en amont de l'entrée d'alimentation en liquide du mélangeur, et peut être actionnée au moyen d'une commande manuelle 25 montée coulissante sur le manche 2 entre un position de fermeture et une position d'ouverture dans lesquelles la vanne est respectivement ouverte et fermée.The two inputs of the mixer are respectively connected to the air compressor and to the cleaning liquid tank via an air supply duct and a liquid supply duct. The two feed pipes of the mixer exit from the handle 2 through one of its ends 22. The outlet of the mixer is here connected to a connection nozzle 23 by means of a spray duct 24. In addition, a another air duct connects a point to the mixer air supply duct, located just upstream of the mixer inlet, at a point in the spray duct, located just downstream of the mixer outlet. A valve is mounted on the liquid conduit, upstream of the liquid supply inlet of the mixer, and can be actuated by means of a manual control 25 slidingly mounted on the handle 2 between a closed position and a position in which the valve is respectively open and closed.
La partie d'extrémité 21 du manche 2 opposée à l'extrémité 22 reliée à la base du dispositif de pulvérisation est taraudée intérieurement.The end part 21 of the handle 2 opposite the end 22 connected to the base of the spraying device is internally threaded.
Un élément de jonction 3, destiné à relier la tête de nettoyage 1 et le manche 2, comprend une portion de vissage 31, en forme d'anneau fileté extérieurement, destinée à être vissée dans la partie d'extrémité 21 du manche 2, et une portion en forme de douille à double baïonnette 32 pour la fixation à la tête de nettoyage 1, la portion de vissage 31 et la douille à double baïonnette 32 étant reliée l'une à l'autre par un tronc de cône 33 convergeant depuis la portion de vissage 31 vers la douille à baïonnette 32.A joining element 3, intended to connect the cleaning head 1 and the handle 2, comprises a screwing portion 31, in the form of an externally threaded ring, intended to be screwed into the end part 21 of the handle 2, and a portion in the form of a double bayonet socket 32 for fixing to the cleaning head 1, the screwing portion 31 and the double bayonet socket 32 being connected to each other by a truncated cone 33 converging from the screw portion 31 to the bayonet socket 32.
La douille à baïonnette 32, légèrement évasée vers l'extérieur, ménage deux fentes 34 de réception d'un téton à baïonnette 12, identiques et symétriques l'une de l'autre par rapport à l'axe de la douille 32. Chaque fente 34 comprend deux portions 36, 37 sensiblement rectangulaires s'étendant longitudinalement dans deux plans respectifs perpendiculaires à l'axe de la douille 32, légèrement décalées l'une de l'autre le long de l'axe de la douille 32 et perpendiculairement à celui-ci, et communiquant l'une avec l'autre, à l'une de leurs extrémités longitudinales, par une autre portion de fente sensiblement rectangulaire. Une encoche 39 d'encliquetage d'un téton à baïonnette 12 est ménagée dans le bord extérieur, autrement dit le bord le plus proche de l'extrémité libre de la douille à baïonnette 32, de la portion de fente 37 intérieure, autrement dit la plus proche du tronc de cône 33, à l'extrémité de la portion de fente 37 opposée à celle reliée aux autres portions de fente 36 et 38. Un anneau de recouvrement 35 entoure la douille à baïonnette 32.The bayonet socket 32, slightly flared towards the outside, provides two slots 34 for receiving a bayonet stud 12, identical and symmetrical to each other with respect to the axis of the socket 32. Each slot 34 comprises two substantially rectangular portions 36, 37 extending longitudinally in two respective planes perpendicular to the axis of the sleeve 32, slightly offset from each other along the axis of the sleeve 32 and perpendicular to that -ci, and communicating with each other, at one of their longitudinal ends, by another substantially rectangular slot portion. A notch 39 for latching a bayonet stud 12 is formed in the outer edge, in other words the edge closest to the free end of the bayonet socket 32, of the inner slot portion 37, in other words the closer to the truncated cone 33, at the end of the slot portion 37 opposite to that connected to the other slot portions 36 and 38. A covering ring 35 surrounds the bayonet socket 32.
La tête de nettoyage 1, de forme générale cylindrique, comprend une extrémité de fixation 11 comportant deux tétons à baïonnette 12, 12', diamétralement opposée l'un de l'autre.The cleaning head 1, of generally cylindrical shape, comprises a fixing end 11 comprising two bayonet pins 12, 12 ′, diametrically opposite one from the other.
L'autre partie d'extrémité 13 de la tête de nettoyage 1, opposée à l'extrémité de fixation 11, supporte des poils de brossage 19 implantés dans une zone d'implantation 15, ici plane et sensiblement parallèle à l'axe longitudinal 41 de la tête de nettoyage 1. Les poils de brossage 19 s'étendent perpendiculairement à la zone d'implantation 15. La hauteur des poils de brossage 19 est telle que les poils 19 forment un gabarit pour positionner une buse de pulvérisation 18, explicitée plus loin, à une distance prédéterminée par rapport à des dents à nettoyer, distance pour laquelle le nettoyage est le plus efficace, compte tenu de la compression de l'air.The other end portion 13 of the cleaning head 1, opposite the end fixing 11, supports brush bristles 19 implanted in an implantation zone 15, here flat and substantially parallel to the longitudinal axis 41 of the cleaning head 1. The brush bristles 19 extend perpendicular to the zone d implantation 15. The height of the brushing bristles 19 is such that the bristles 19 form a template for positioning a spray nozzle 18, explained below, at a predetermined distance from the teeth to be cleaned, distance for which cleaning is the most efficient, considering the air compression.
Un conduit de pulvérisation 16 s'étend à l'intérieur de la tête de nettoyage 1, sensiblement le long de son axe longitudinal 41. L'une des extrémités du conduit de pulvérisation 16 constitue un orifice de raccord 17 s'étendant dans un plan perpendiculaire à l'axe 41, à l'extrémité de fixation 17. L'autre extrémité du conduit 16 est coudée et débouche par la buse de pulvérisation 18 dans une zone plane prolongeant vers l'arrière (c'est-à-dire vers l'extrémité 11) la zone d'implantation 15. La buse de pulvérisation 18 s'étend ainsi en dehors de la zone 15 d'implantation des poils 19, au voisinage, et ici à l'arrière, des poils 19.A spray duct 16 extends inside the cleaning head 1, substantially along its longitudinal axis 41. One end of the spray duct 16 constitutes a connection orifice 17 extending in a plane perpendicular to the axis 41, at the fixing end 17. The other end of the duct 16 is bent and opens out by the spray nozzle 18 in a flat area extending towards the rear (that is to say towards the end 11) the implantation zone 15. The spray nozzle 18 thus extends outside the zone 15 of implantation of the bristles 19, in the vicinity, and here at the rear, of the bristles 19.
Le montage de la tête de nettoyage 1 sur son manche de réception 2 et une opération de nettoyage de dents vont maintenant être décrits.The mounting of the cleaning head 1 on its receiving handle 2 and a tooth cleaning operation will now be described.
L'élément de jonction 3 est vissé dans la partie d'extrémité 21 du manche 2. Le conduit de pulvérisation 24 sortant du mélangeur air-liquide s'étend alors le long de l'axe 43 de l'élément de jonction 3, la buse de raccord 23 dépassant légèrement le plan de jonction du tronc de cône 33 et de la douille à baïonnette 32, du côté de la douille 32.The joining element 3 is screwed into the end part 21 of the handle 2. The spray duct 24 exiting from the air-liquid mixer then extends along the axis 43 of the joining element 3, the connection nozzle 23 slightly projecting from the junction plane of the truncated cone 33 and the bayonet socket 32, on the side of the socket 32.
Puis, on introduit les deux tétons à baïonnette 12, 12' respectivement dans les deux fentes 34 de la douille à baïonnette 32, en positionnant la tête de nettoyage 1 de façon à ce que les axes 41, 42 et 43 de la tête de nettoyage 1, du manche 2 et de l'élément de jonction 3 soient confondus. On tourne la tête de nettoyage 1 autour de son axe 41 jusqu'à ce que les tétons 12, 12' viennent s'encliqueter dans les encoches d'encliquetage 39. Lors de la fixation de la tête de nettoyage 1 à l'élément de jonction 3, la buse de raccord 23 du conduit de pulvérisation 24 sortant du mélangeur est introduit dans le conduit de pulvérisation 16 de la tête de nettoyage 1 par l'orifice de raccord 17.Then, the two bayonet pins 12, 12 ′ are respectively introduced into the two slots 34 of the bayonet socket 32, by positioning the cleaning head 1 so that the axes 41, 42 and 43 of the cleaning head 1, the handle 2 and the junction element 3 are combined. The cleaning head 1 is rotated about its axis 41 until the pins 12, 12 ′ snap into the snap-in notches 39. When the cleaning head 1 is fixed to the junction 3, the connection nozzle 23 of the spray duct 24 leaving the mixer is introduced into the spray duct 16 of the cleaning head 1 through the connection orifice 17.
Pour nettoyer les dents, on met en marche la base du dispositif de pulvérisation. La vanne du mélangeur étant initialement fermée, le mélangeur n'est alimenté qu'en air comprimé et, par conséquent, la buse de pulvérisation 18 n'éjecte que de l'air comprimé.To clean the teeth, turn on the base of the spray. The mixer valve being initially closed, the mixer is only supplied with compressed air and, consequently, the spray nozzle 18 only ejects compressed air.
On positionne l'extrémité de brossage et de pulvérisation 13 de la tête de nettoyage 1 au voisinage de l'une des dents à nettoyer, en appliquant l'extrémité libre des poils de brossage 19 sur la dent, la buse de pulvérisation 15 est ainsi positionnée à une distance des dents pour laquelle le nettoyage est le plus efficace compte tenu de la compression de l'air.The brushing and spraying end 13 of the cleaning head 1 is positioned in the vicinity of one of the teeth to be cleaned, by applying the free end of the brushing bristles 19 to the tooth, the spray nozzle 15 is thus positioned at a distance from the teeth for which cleaning is most effective given the air compression.
Puis, on fait coulisser la commande manuelle 25 de la vanne de sa position de fermeture à sa position d'ouverture de façon à ouvrir la vanne du mélangeur. De l'air et du liquide de nettoyage alimentent alors le mélangeur et de l'air est également injecté dans le mélange à la sortie du mélangeur. Le mélange résultant est éjecté par la buse de raccord 23 dans le conduit de pulvérisation 16 de la tête de nettoyage 1 puis pulvérisé par la buse de pulvérisation 18 sur les dents à nettoyer. Concomitamment à la pulvérisation, on déplace la tête de nettoyage 1 sur les dents à nettoyer en brossant les dents avec les poils de brossage, la tête de nettoyage étant toujours maintenue à la même distance des dents.Then, the manual control 25 of the valve is made to slide from its closed position to its open position so as to open the mixer valve. Air and cleaning liquid then feed the mixer and air is also injected into the mixture at the outlet of the mixer. The resulting mixture is ejected through the connection nozzle 23 into the spray duct 16 of the cleaning head 1 and then sprayed by the spray nozzle 18 onto the teeth to be cleaned. Concomitantly with the spraying, the cleaning head 1 is moved over the teeth to be cleaned by brushing the teeth with the brushing bristles, the cleaning head being always kept at the same distance from the teeth.
Lors de la pulvérisation et du brossage, les gouttelettes d'eau pulvérisées viennent frapper contre les dents sur une surface étendue en désorganisant la plaque dentaire et les poils de brossage décollent la plaque dentaire. L'action combinée de la pulvérisation et du brossage permet d'éliminer la totalité de la plaque dentaire en une durée bien inférieure à la celle nécessaire pour obtenir le même résultat en pulvérisant un mélange de liquide de nettoyage et d'air comprimé sans brossage.During spraying and brushing, the sprayed water droplets strike against the teeth over a large area, disorganizing the dental plaque and the brushing bristles peel off the dental plaque. The combined action of spraying and brushing makes it possible to remove all of the dental plaque in a time much less than that necessary to obtain the same result by spraying a mixture of cleaning liquid and compressed air without brushing.
Au lieu d'être située à l'arrière de la zone d'implantation des poils, la buse de pulvérisation pourrait être située en dehors de la zone d'implantation des poils, mais à l'avant de celle-ci (c'est-à-dire du côté de l'extrémité 13). Instead of being located at the rear of the hair implantation area, the spray nozzle could be located outside the hair implantation area, but at the front of it (this is ie on the end side 13).
