Description

Domaine techniqueTechnical area

La présente invention concerne le domaine des aspirateurs équipés d'un suceur d'aspirateur, également nommé tête de succion, permettant d'aspirer les poussières et les déchets de faible granulométrie présents sur une surface.The present invention relates to the field of vacuum cleaners equipped with a suction nozzle, also called suction head, to suck dust and small-size waste present on a surface.

Etat de la techniqueState of the art

Les aspirateurs équipés d'un suceur d'aspirateur sont bien connus sur le marché, ceux-ci permettant de nettoyer des surfaces par aspiration pour l'évacuation des poussières et des déchets de faible granulométrie reposant sur celles-ci. La surface à aspirer peut par exemple être du carrelage, du parquet, du stratifié, de la moquette ou un tapis.Vacuums equipped with a suction nozzle are well known on the market, they allow cleaning surfaces by suction for the evacuation of dust and small size waste based on them. The surface to be vacuumed may for example be tiled, parquet, laminate, carpet or carpet.

Un suceur d'aspirateur comprend traditionnellement un manchon de raccordement et une semelle munie d'une face inférieure et d'un canal d'aspiration communiquant avec le manchon de raccordement et débouchant sur la face inférieure de la semelle. La face inférieure de la semelle est destinée à être positionnée de manière attenante à la surface à aspirer durant l'utilisation du suceur d'aspirateur.A suction nozzle traditionally comprises a connecting sleeve and a sole provided with a lower face and a suction channel communicating with the connecting sleeve and opening on the underside of the sole. The underside of the soleplate is intended to be positioned adjacent to the surface to be sucked during use of the vacuum nozzle.

La semelle du suceur d'aspirateur peut par exemple être pourvue d'un canal d'aspiration s'étendant transversalement à une direction de déplacement du suceur d'aspirateur, et d'une surface de glissement avant et d'une surface de glissement arrière situées de part et d'autre du canal d'aspiration.The sole of the suction nozzle may for example be provided with a suction channel extending transversely to a direction of movement of the vacuum nozzle, and a front sliding surface and a rear sliding surface. located on both sides of the suction channel.

Une telle configuration du suceur d'aspirateur induit une pression d'aspiration plus importante dans la partie centrale du canal d'aspiration que dans les portions latérales du canal d'aspiration, et ce du fait que le canal d'aspiration est relié au manchon de raccordement par l'intermédiaire d'un conduit de liaison débouchant dans la partie centrale du canal d'aspiration. Cette différence d'aspiration entre la partie centrale de la semelle et les bords latéraux de cette dernière peut être une source d'insatisfaction pour un utilisateur.Such a configuration of the suction nozzle induces a greater suction pressure in the central part of the suction channel than in the side portions of the suction channel, and this because the suction channel is connected to the sleeve connection via a connecting conduit opening into the central part of the suction channel. This difference suction between the central portion of the sole and the side edges of the latter can be a source of dissatisfaction for a user.

Résumé de l'inventionSummary of the invention

Une telle configuration de la face inférieure de la semelle favorise un passage d'air au niveau des portions d'extrémité du canal d'aspiration, et garantit ainsi une aspiration satisfaisante sur sensiblement toute la longueur du canal d'aspiration, ce qui améliore les performances du suceur d'aspirateur.Such a configuration of the lower face of the sole promotes an air passage at the end portions of the suction channel, and thus ensures satisfactory suction over substantially the entire length of the suction channel, which improves the performance of the vacuum cleaner.

Description détailléedetailed description

Les figures 1 à 5 représentent un suceur d'aspirateur 2 comprenant un manchon de raccordement 3 à l'extrémité 3a duquel vient se raccorder un embout d'un tube rigide ou flexible, lui-même raccordé au système d'aspiration de l'aspirateur (non illustré). Diverses variantes d'aspirateurs existent déjà sur le marché et pourront être utilisées avec le suceur d'aspirateur 2 selon l'invention ; ces variantes étant connues de l'homme du métier, elles ne sont pas détaillées dans la présente demande de brevet.The Figures 1 to 5 represent a suction nozzle 2 comprising a connecting sleeve 3 at the end 3a which is connected to a tip of a rigid or flexible tube, itself connected to the suction system of the vacuum cleaner (not shown). Various vacuum cleaner variants already exist on the market and may be used with the vacuum nozzle 2 according to the invention; these variants being known to those skilled in the art, they are not detailed in the present patent application.

Le suceur d'aspirateur 2 comprend en outre une fourche 4 et deux roues de déplacement 4a-4b montées sur la fourche 4. Le manchon de raccordement 3 est monté en liaison pivot vis-à-vis de la fourche 4 selon un premier axe de pivotement transversal X1 correspondant de préférence avec l'axe de rotation des roues de déplacement 4a-4b disposées chacune d'un côté de la fourche 4 et du manchon de raccordement 3. On pourrait toutefois prévoir des variantes de suceur d'aspirateur selon l'invention avec un léger décalage de l'axe de rotation des roues de déplacement 4a-4b vers le bas et/ou vers l'arrière vis-à-vis du premier axe de pivotement transversal X1.The suction nozzle 2 further comprises a fork 4 and two displacement wheels 4a-4b mounted on the fork 4. The connecting sleeve 3 is mounted in pivot connection with respect to the fork 4 along a first axis of transverse pivot X1 corresponding preferably with the axis of rotation of the displacement wheels 4a-4b each disposed on one side of the fork 4 and the connecting sleeve 3. However, it is possible to provide variants of vacuum nozzle according to the invention. invention with a slight shift of the axis of rotation of the displacement wheels 4a-4b downwardly and / or rearwardly vis-à-vis the first transverse pivot axis X1.

Le suceur d'aspirateur 2 comprend de plus une semelle 5 par exemple en matière plastique. La fourche 4 est montée en liaison pivot vis-à-vis de la semelle 5 selon un deuxième axe de pivotement transversal X2. Pour cela, la fourche 4 comprend deux branches 6, 7 pourvues chacune, par exemple, d'un orifice (non visible sur les figures) recevant à pivotement un plot respectif prévu à l'arrière de la semelle 5.The suction nozzle 2 further comprises a sole 5 for example of plastic. The fork 4 is mounted in pivot connection with respect to the sole 5 along a second axis of transverse pivoting X2. For this, the fork 4 comprises two branches 6, 7 each provided, for example, with an orifice (not visible in the figures) pivotally receiving a respective stud provided at the rear of the sole 5.

Ainsi, le manchon de raccordement 3 peut basculer vers l'avant ou vers l'arrière par rapport à la fourche 4, comme l'illustrent respectivement les flèches 10a et 10b sur la figure 4, et la fourche 4 peut également basculer vers l'avant ou vers l'arrière par rapport à la semelle 5, comme l'illustrent respectivement les flèches 9a et 9b sur la figure 4.Thus, the connecting sleeve 3 can tilt forwards or backwards with respect to the fork 4, as illustrated respectively by the arrows 10a and 10b on the figure 4 , and the fork 4 can also tilt forwards or backwards relative to the sole 5, as shown respectively by the arrows 9a and 9b on the figure 4 .
