Abstract

A hand piece housing (1) comprises a valve body (2) and a spray body (3) with several outlets. The valve body has a supply duct (4), connected to a pump and is controlled by a rotatable disc (5) which has a single fluid duct (6). In the same plane as the supply duct are outlet ducts (7,8) connected to further ducts (9,10) of the pluggable spray body, sealed by O-rings (14) and held in place by a clamp (15). The control disc has at its front end a toothed segment which engages a toothed rack of an extension (17) fixed to an adjuster slide (16) for rotating the controls disc.

Description

La présente invention concerne une poignée pour douches buccales reliée à un dispositif de pompe par un tube flexible, et qui porte un corps de buse débrochable à simple ou à jet multiple, et qui comporte à l'entrée d'autre part un dispositif de commande relié à un curseur, lui-même relié au tuyau flexible, pour obtenir à la sortie un jet simple ou multiple.The present invention relates to a handle for oral showers connected to a pump device by a flexible tube, and which carries a withdrawable nozzle body with single or multiple jet, and which comprises at the input on the other hand a control device connected to a slider, itself connected to the flexible hose, to obtain a single or multiple jet at the outlet.

Dans une poignée pour hydropulseur buccal et dentaire connue (DE-A 31 01 941) se trouve un obturateur à cône contrôlant le flux de liquide, relié à une douille coulissante à l'aide d'un curseur de positionnement disposé à l'extérieur sur la poignée, à positions d'ouverture ou de fermeture, tandis qu'un curseur de commande relié à la douille coulissante permet les commutations entre les positions d'emploi à projection simple ou multiple. La disposition du cône d'obturation de la douille coulissante et du curseur de commande, entraîne une grande longueur de la poignée et une réalisation compliquée de celle-ci. En plus le remplacement du tube de buse sur cette poignée est pénible.Dans une autre poignée connue d'un dispositif de lavage buccale (DE-A 30 44 025), il est prévu dans ladite poignée un piston coulissant doté de canaux et déplaçable longitudinalement à l'aide d'un curseur, qui suivant sa position libère ou obture l'arrivée du liquide, à partir d'une entrée commune et unique, vers les sorties du dispositif à buse à jet simple ou à jet multiple. Mise à part que le piston avec sa buse dont il a besoin conduit à de longues manipulations, il n'est pas prévu la possibilité de remplacer le corps à buse sur cette poignée.In a handle for a known oral and dental hydropulser (DE-A 31 01 941) there is a cone shutter controlling the flow of liquid, connected to a sliding bushing by means of a positioning cursor positioned outside on the handle, in open or closed positions, while a control cursor connected to the sliding bush allows switching between the positions of use with single or multiple projection. The arrangement of the shutter cone of the sliding bushing and the control cursor results in a long length of the handle and a complicated production thereof. In addition the replacement of the nozzle tube on this handle is painful. In another known handle of an oral washing device (DE-A 30 44 025), there is provided in said handle a sliding piston provided with channels and movable longitudinally using a slider, which, depending on its position, releases or blocks the arrival of the liquid, from a common and single inlet, towards the outlets of the device with a single jet or multiple jet nozzle. Apart from the fact that the piston with its nozzle which it needs leads to long manipulations, there is no provision for the possibility of replacing the nozzle body on this handle.

L'objet de l'invention est de créer des dispositifs économisant de la place, tout en permettant d'obtenir la séparation et la liaison étanche entre l'alimentation et les sorties. The object of the invention is to create devices which save space, while making it possible to obtain the separation and the sealed connection between the supply and the outputs.

Suivant l'invention ceci est obtenu par le fait que dans le même plan la poignée ne possède qu'unie seule alimentation et des sorties à jet simple ou multiple, et par le fait qu'entre l'alimentation et les deux sorties est disposé un disque rotatif de commande à un seul conduit de liquide, qui relie ou coupe au choix l'arrivée avec l'une ou l'autre sortie. La disposition de l'alimentation unique et des sorties dans le même plan, demande peu de surface d'étanchéité et conduit au faible encombrement de la poignée, ainsi qu'a une manipulation facilitée du curseur de positionnement.Le passage du liquide est avantagé à travers le disque de commande en raison de sa forme d'entonnoir qui présente à l'entrée une section essentiellement rectangulaire, se prolongeant en une section circulaire, grâce à quoi sont assurés des passages de liquide depuis l'alimentation jusqu'à l'une ou l'autre sortie, sans problème. Par essentiellement rectangulaire, il faut comprendre une section elliptique longitudinale ou rectangle avec des angles arrondis. En plus il a été prévu que l'alimentation et les sorties ainsi que le disque de commande soient disposés dans un corps de soupape monté dans un boîtier.According to the invention this is obtained by the fact that in the same plane the handle has only a single supply and single or multiple jet outputs, and by the fact that between the supply and the two outputs is arranged a rotary control disc with a single liquid conduit, which connects or cuts the inlet with either outlet. The arrangement of the single supply and the outlets in the same plane, requires little sealing surface and leads to the small size of the handle, as well as to an easier manipulation of the positioning slider. The passage of the liquid is advantageous to through the control disc due to its funnel shape which has a substantially rectangular section at the inlet, extending into a circular section, whereby liquid passages are ensured from the feed to one either way, no problem. By essentially rectangular is meant a longitudinal elliptical or rectangle section with rounded angles. In addition, provision has been made for the supply and outputs as well as the control disc to be arranged in a valve body mounted in a housing.

Dans le mode de réalisation de la poignée, il est prévu de coupler le disque de commande et le curseur de positionnement, soit à l'aide d'un engrenage par exemple à crémaillère ou à manivelle, soit à l'aide d'un dispositif à fentes de serrage.In the embodiment of the handle, provision is made to couple the control disc and the positioning slider, either using a gear, for example a rack or crank, or using a device. with clamping slots.

Les figures des dessins annexés feront bien comprendre comment l'invention pourra être réalisée.The figures of the appended drawings will make it easy to understand how the invention can be implemented.

La figure 1 est une coupe de la poignée. Figure 1 is a section of the handle.

La figure 2 est un élément de la poignée.Figure 2 is an element of the handle.

La figure 3 est une coupe partielle d'une poignée.Figure 3 is a partial section of a handle.

La figure 4 est une autre coupe de poignée.Figure 4 is another handle section.

La figure 5 est un aggrandissement de la coupe d'un disque de commande.Figure 5 is an enlargement of the section of a control disc.

La figure 6 est une coupe d'un disque de commande.Figure 6 is a section through a control disc.

La figure 7 est un disque de commande en vue latéral.Figure 7 is a control disc in side view.

Sur les figures, le boîtier de la poignée désigné par 1 possède un corps de soupape 2, un corps de buse 3 à sortie simple et multiple (non représentée). Le corps à soupape 2 est munie d'une alimentation 4, liée par l'intermédiaire d'un tuyau flexible, avec un dispositif de pompe. L'alimentation 4 est contrôlée par un disque de commande rotatif 5 qui ne possède qu'un seul conduit de liquide 6. Dans le même plan que l'alimentation 4, se trouve les sorties 7 et 8, celles-ci sont en liaison avec la sortie à jet simple respectivement à jet multiple par l'intermédiaire des canaux 9 et 10 d'un corps à buse embrochable 3. Le corps à buse 3 est maintenu dans le corps de soupape 2, et guidé de façon étanche à l'aide d'anneaux torriques 14 et d'un corps de blocage 15.Le disque de commande 5 sur un embout frontal porte un segment denté 12 débordant le corps de soupape, qui engrène une crémaillère 13 d'un curseur de positionnement 16 fixé à l'aide d'appendices 17 et monté de façon coulissante sur le boîtier de la poignée 1, de façon que dans les déplacements longitudinaux du curseur de positionnement, le disque de commande 5 est tourné. Comme reconnaissable surtout sur les figures 3,4 et 6, le passage du liquide 6 est avantagé par la forme d'entonnoir passant d'une section essentiellement rectangulaire à l'entrée à une section circulaire à la sortie.In the figures, the handle housing designated by 1 has a valve body 2, a nozzle body 3 with a single and multiple outlet (not shown). The valve body 2 is provided with a supply 4, linked via a flexible hose, with a pump device. The supply 4 is controlled by a rotary control disc 5 which has only one liquid conduit 6. In the same plane as the supply 4, are the outputs 7 and 8, these are in connection with the outlet with single jet or multiple jet respectively via the channels 9 and 10 of a plug-in nozzle body 3. The nozzle body 3 is held in the valve body 2, and guided tightly using O-rings 14 and a blocking body 15. The control disc 5 on a front end carries a toothed segment 12 projecting from the valve body, which meshes with a rack 13 of a positioning slider 16 fixed to the using appendages 17 and slidably mounted on the housing of the handle 1, so that in the longitudinal movements of the positioning cursor, the control disc 5 is rotated. As can be seen above all in FIGS. 3,4 and 6, the passage of the liquid 6 is favored by the shape of the funnel passing from an essentially rectangular section at the inlet to a circular section at the outlet.

Sur la figure 1, le disque de commande 5 et le curseur de positionnement 16 prennent la position d'arrêt. Dans ce cas l'alimentation 4 et les sorties 7 et 8 sont séparées l'une de l'autre alors que les appendices coulissants 17 libèrent l'élément de blocage 15 pour permettre l'interchangeabilité de la buse 3. Par le déplacement longitudinal du curseur 16 dans la direction de la buse, le disque de commande 5 est tourné dans la position de la figure 3 par l'intermédiaire d'un segment denté 12 et de la crémaillère 13, ce qui branche l'alimentation 4 sur la sortie 7 par le conduit de liquide 6. En continuant le déplacement du curseur 16 vers la position de la figure 4, on relie le conduit 6 avec la sortie 8. In FIG. 1, the control disc 5 and the positioning cursor 16 assume the stop position. In this case the supply 4 and the outputs 7 and 8 are separated from each other while the sliding appendages 17 release the locking element 15 to allow the interchangeability of the nozzle 3. By the longitudinal displacement of the cursor 16 in the direction of the nozzle, the control disc 5 is rotated in the position of FIG. 3 by means of a toothed segment 12 and of the rack 13, which connects the power supply 4 to the outlet 7 by the liquid conduit 6. Continuing the movement of the cursor 16 towards the position of FIG. 4, the conduit 6 is connected with the outlet 8.
