  • the underside of the soleplate is intended to be positioned adjacent to the surface to be vacuumed during use of the suction head.
  • closure cap increases the size of the closure cap and therefore of the cleaning unit, and can induce untimely unlocking of the closure cap during, for example, an impact of the closure cap against an obstacle. .
  • a cleaning unit according to the preamble of claim 1 is already described for example in the document WO-A-2020020862 .
  • the present invention aims to remedy all or part of these drawbacks.
  • the technical problem underlying the invention consists in particular in providing a cleaning unit for a suction head ensuring easy and ergonomic handling of the closure cap, while ensuring reliable locking of the closure cap on the main body of the suction head.
  • the closure cap has a gripping handle that is movable between a rest position and a gripping position in which the gripping handle is configured to be gripped by a user so as to be able to manipulate the closing plug, and for example in such a way as to be able to withdraw the rotating brush from the receiving housing when the rotating brush is mounted in the receiving housing.

Une tête d'aspiration comprend de façon connue un corps principal comportant une semelle munie d'une face inférieure et d'un orifice d'aspiration débouchant dans 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 de la tête d'aspiration.A suction head comprises, in known manner, a main body comprising a sole provided with a lower face and with a suction orifice opening out into the lower face of the sole. The underside of the soleplate is intended to be positioned adjacent to the surface to be vacuumed during use of the suction head.

Afin d'améliorer les performances de nettoyage d'une tête d'aspiration, il est connu d'équiper cette dernière d'une unité de nettoyage comprenant :

  • une brosse rotative qui est mobile en rotation autour d'un axe de rotation et qui est montée de manière amovible dans un logement de réception délimité par le corps principal de la tête d'aspiration, et
  • un bouchon de fermeture qui est configuré pour fermer au moins partiellement une ouverture de passage prévue sur le corps principal et à travers laquelle la brosse rotative est apte à être introduite dans et retirée hors du logement de réception, la brosse rotative étant rotative par rapport au bouchon de fermeture.
In order to improve the cleaning performance of a suction head, it is known to equip the latter with a cleaning unit comprising:
  • a rotary brush which is rotatable about a rotation axis and which is removably mounted in a receiving housing delimited by the main body of the suction head, and
  • a closing cap which is configured to at least partially close a passage opening provided on the main body and through which the rotary brush is adapted to be inserted into and withdrawn from the receiving housing, the rotary brush being rotatable with respect to the closure cap.

Afin de permettre une manipulation du bouchon de fermeture par un utilisateur, notamment lors d'un retrait de la brosse rotative en vue par exemple de son nettoyage, il est connu d'équiper le bouchon de fermeture de deux ailettes de préhension qui sont diamétralement opposées par rapport à l'axe de rotation de la brosse rotative et qui font saillie depuis une surface frontale du bouchon de fermeture.In order to allow manipulation of the closure cap by a user, in particular when removing the rotating brush with a view to cleaning it, for example, it is known to equip the closure cap with two gripping fins which are diametrically opposed. with respect to the axis of rotation of the rotating brush and which protrude from a front surface of the closure cap.

Or, une telle configuration du bouchon de fermeture augmente l'encombrement du bouchon de fermeture et donc de l'unité de nettoyage, et peut induire un déverrouillage intempestif du bouchon de fermeture lors par exemple d'un impact du bouchon de fermeture contre un obstacle.However, such a configuration of the closure cap increases the size of the closure cap and therefore of the cleaning unit, and can induce untimely unlocking of the closure cap during, for example, an impact of the closure cap against an obstacle. .

Afin de limiter l'encombrement du bouchon de fermeture, il peut être envisagé de diminuer les dimensions des deux ailettes de préhension, ce qui rend cependant malaisé la manipulation du bouchon de fermeture pour certains utilisateurs. Une unité de nettoyage selon le préambule de la revendication 1 est déjà décrite par exemple dans le document WO-A-2020020862 .In order to limit the size of the closure cap, it may be envisaged to reduce the dimensions of the two gripping fins, which however makes handling of the closure cap difficult for certain users. A cleaning unit according to the preamble of claim 1 is already described for example in the document WO-A-2020020862 .

Résumé de l'inventionSummary of the invention

La présente invention vise à remédier à tout ou partie de ces inconvénients.The present invention aims to remedy all or part of these drawbacks.

Le problème technique à la base de l'invention consiste notamment à fournir une unité de nettoyage pour tête d'aspiration assurant une manipulation aisée et ergonomique du bouchon de fermeture, tout en assurant un verrouillage fiable du bouchon de fermeture sur le corps principal de la tête d'aspiration.The technical problem underlying the invention consists in particular in providing a cleaning unit for a suction head ensuring easy and ergonomic handling of the closure cap, while ensuring reliable locking of the closure cap on the main body of the suction head.

A cet effet, la présente invention concerne une unité de nettoyage pour tête d'aspiration, comprenant :

  • une brosse rotative qui est mobile en rotation autour d'un axe de rotation et qui est configurée pour être montée de manière amovible dans un logement de réception délimité par un corps principal de la tête d'aspiration, et
  • un bouchon de fermeture qui est configuré pour fermer au moins partiellement une ouverture de passage prévue sur le corps principal et à travers laquelle la brosse rotative est apte à être introduite dans le logement de réception et retirée hors du logement de réception, la brosse rotative étant rotative par rapport au bouchon de fermeture.
To this end, the present invention relates to a cleaning unit for a suction head, comprising:
  • a rotary brush which is rotatable about a rotation axis and which is configured to be removably mounted in a receiving housing delimited by a main body of the suction head, and
  • a closure plug which is configured to at least partially close a passage opening provided on the main body and through which the rotating brush is adapted to be inserted into the receiving housing and withdrawn from the receiving housing, the rotating brush being rotatable relative to the closure cap.

Le bouchon de fermeture comporte une poignée de préhension qui est mobile entre une position de repos et une position de préhension dans laquelle la poignée de préhension est configurée pour être saisie par un utilisateur de manière à pouvoir manipuler le bouchon de fermeture, et par exemple de manière à pouvoir retirer la brosse rotative hors du logement de réception lorsque la brosse rotative est montée dans le logement de réception.The closure cap has a gripping handle that is movable between a rest position and a gripping position in which the gripping handle is configured to be gripped by a user so as to be able to manipulate the closing plug, and for example in such a way as to be able to withdraw the rotating brush from the receiving housing when the rotating brush is mounted in the receiving housing.

Une telle configuration de la poignée de préhension assure notamment un retrait aisé et ergonomique de la brosse rotative hors du logement de réception lorsque la poignée de préhension occupe la position de préhension, tout en limitant l'encombrement du bouchon de fermeture et donc de l'unité de nettoyage sur la tête d'aspiration, lorsque la poignée de préhension occupe la position de repos. De plus, une telle configuration de la poignée de préhension, et en particulier le fait que la poignée de préhension occupe la position de repos en conditions normales d'utilisation de la tête d'aspiration, limite considérablement les risques de déverrouillage intempestif du bouchon de fermeture.Such a configuration of the grip handle ensures in particular easy and ergonomic removal of the rotary brush from the receiving housing when the grip handle occupies the grip position, while limiting the size of the closure cap and therefore of the cleaning unit on the suction head, when the grip handle is in the rest position. In addition, such a configuration of the grip handle, and in particular the fact that the grip handle occupies the rest position under normal conditions of use of the suction head, considerably limits the risks of inadvertent unlocking of the closing.

L'unité de nettoyage peut en outre présenter une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison.The cleaning unit may further have one or more of the following features, taken alone or in combination.

Selon un mode de réalisation de l'invention, la poignée de préhension est configurée pour délimiter, lorsque la poignée de préhension occupe la position de préhension, au moins partiellement un passage de préhension apte à recevoir au moins un doigt d'un utilisateur.According to one embodiment of the invention, the gripping handle is configured to delimit, when the gripping handle occupies the gripping position, at least partially a gripping passage capable of receiving at least one finger of a user.

Selon un mode de réalisation de l'invention, la poignée de préhension s'étend sensiblement dans un plan de repos lorsque la poignée de préhension occupe la position de repos, le plan de repos s'étendant transversalement, et par exemple sensiblement perpendiculairement, à l'axe de rotation de la brosse rotative.According to one embodiment of the invention, the gripping handle extends substantially in a rest plane when the gripping handle occupies the rest position, the resting plane extending transversely, and for example substantially perpendicularly, to the axis of rotation of the rotating brush.

Selon un mode de réalisation de l'invention, la poignée de préhension s'étend sensiblement dans un plan de préhension lorsque la poignée de préhension occupe la position de préhension, le plan de préhension s'étendant sensiblement parallèlement à l'axe de rotation de la brosse rotative.According to one embodiment of the invention, the gripping handle extends substantially in a gripping plane when the gripping handle occupies the gripping position, the gripping plane extending substantially parallel to the axis of rotation of the rotating brush.

Selon un mode de réalisation de l'invention, dans la position de repos de la poignée de préhension, la poignée de préhension est logée dans un logement de poigné formé par une cavité du bouchon de fermeture.According to one embodiment of the invention, in the rest position of the grip handle, the grip handle is housed in a handle housing formed by a cavity of the closure cap.

Selon un mode de réalisation de l'invention, dans la position de repos de la poignée de préhension, la poignée de préhension est logée dans un logement de poigné formé par une cavité du bouchon de fermeture et est arrangée pour sensiblement affleurer ou être en retrait d'une surface extérieure du bouchon de fermeture. Ladite surface extérieure entoure la cavité du bouchon. En d'autres termes, dans la position de repos la poignée de préhension est logée dans une cavité du bouchon de fermeture et est arrangée pour ne pas faire saillie, ou que très légèrement, au-delà de la surface extérieure du bouchon de fermeture qui entoure la cavité du bouchon de fermeture. En effet, du fait des tolérances d'assemblage et jeux de fonctionnement, dans la position de repos de la poignée de préhension, la poignée de préhension pourrait être légèrement en saillie, de l'ordre de quelques dixièmes de millimètres jusqu'à environ 1 mm, au-delà de la surface extérieure du bouchon de fermeture qui entoure la cavité du bouchon de fermeture. La terminologie « sensiblement affleurante » couvre donc une saillie inférieure à 1mm de la poignée de préhension en position de repos par rapport à la surface extérieure du bouchon de fermeture qui entoure la cavité du bouchon.According to one embodiment of the invention, in the rest position of the grip handle, the grip handle is housed in a handle housing formed by a cavity of the closure cap and is arranged to be substantially flush or recessed an outer surface of the closure cap. Said outer surface surrounds the cavity of the stopper. In other words, in the rest position the grip handle is housed in a cavity of the closure cap and is arranged not to protrude, or only very slightly, beyond the outer surface of the closure cap which surrounds the cavity of the closure cap. Indeed, due to assembly tolerances and operating clearances, in the rest position of the grip handle, the grip handle could protrude slightly, of the order of a few tenths of a millimeter up to approximately 1 mm, beyond the outer surface of the closure plug which surrounds the cavity of the closure plug. The terminology “substantially flush” therefore covers a projection of less than 1 mm from the handle in the rest position with respect to the outer surface of the closing cap which surrounds the cavity of the cap.

Ainsi en position de repos, la poignée de préhension est discrète. Cette construction limite le risque d'accrochage inopiné de la poignée lorsque la tête d'aspiration en déplacement sur le sol à aspirer.Thus in the rest position, the grip handle is discreet. This construction limits the risk of the handle accidentally snagging when the suction head is moving on the floor to be vacuumed.

Dans une variante au mode de réalisation juste précité, dans la position de repos de la poignée de préhension, la poignée de préhension est logée dans un logement de poigné formé par une cavité du bouchon de fermeture et est arrangée pour sensiblement affleurer ou être en retrait d'une surface extérieure du bouchon de fermeture qui entoure la cavité du bouchon de fermeture, à l'exception d'une saillie de préhension de la poignée de préhension qui est configurée pour être saisie par un utilisateur lorsque la poignée de préhension occupe la position de repos de manière à pourvoir déplacer la poignée de préhension de la position de repos à la position de préhension.In a variant to the embodiment just mentioned, in the rest position of the grip handle, the grip handle is housed in a handle housing formed by a cavity of the closure cap and is arranged to be substantially flush or set back an exterior surface of the closure cap that surrounds the cavity of the closure cap, except for a gripping projection of the grip handle which is configured to be grasped by a user when the grip handle is in the position rest so as to be able to move the grip handle from the rest position to the grip position.

Selon un mode de réalisation de l'invention, la poignée de préhension est montée pivotante entre la position de repos et la position de préhension autour d'un axe de pivotement.According to one embodiment of the invention, the gripping handle is pivotally mounted between the rest position and the gripping position around a pivot axis.

Selon un mode de réalisation de l'invention, l'axe de pivotement de la poignée de préhension est sensiblement perpendiculaire à l'axe de rotation de la brosse rotative.According to one embodiment of the invention, the axis of pivoting of the gripping handle is substantially perpendicular to the axis of rotation of the rotary brush.

Selon un mode de réalisation de l'invention, le bouchon de fermeture comporte un corps de bouchon et des moyens de verrouillage configurés pour verrouiller le corps de bouchon sur le corps principal.According to one embodiment of the invention, the closure cap comprises a cap body and locking means configured to lock the cap body to the main body.

Selon un mode de réalisation de l'invention, les moyens de verrouillage comportent au moins un organe de verrouillage qui est mobile par rapport au corps de bouchon entre une position de verrouillage dans laquelle l'au moins un organe de verrouillage coopère avec au moins un élément de verrouillage prévu sur le corps principal de manière à empêcher un retrait de la brosse rotative hors du logement de réception et une position de libération dans laquelle l'au moins un organe de verrouillage libère l'au moins un élément de verrouillage de manière à autoriser un retrait de la brosse rotative hors du logement de réception.According to one embodiment of the invention, the locking means comprise at least one locking member which is movable relative to the cap body between a locking position in which the at least one locking member cooperates with at least one locking element provided on the main body so as to prevent withdrawal of the rotary brush from the receiving housing and a release position in which the at least one locking member releases the at least one locking element so as to allow removal of the rotating brush from the receiving housing.

Une telle configuration du bouchon de fermeture garantit un verrouillage aisé et ergonomique du corps de bouchon sur le corps principal de la tête d'aspiration. En outre, une telle configuration du bouchon de fermeture assure un maintien efficace du corps de bouchon dans l'ouverture de passage et donc de la brosse rotative dans le logement de réception, et limite sensiblement la génération de vibrations par la brosse rotative lors de la rotation de cette dernière. De ce fait, l'unité de nettoyage selon la présente invention limite grandement le transfert de vibrations de la brosse rotative au corps principal de la tête d'aspiration, et assure un confort d'utilisation accru pour un utilisateur.Such a configuration of the closure cap guarantees easy and ergonomic locking of the cap body on the main body of the suction head. In addition, such a configuration of the closure plug ensures effective maintenance of the plug body in the passage opening and therefore of the rotating brush in the receiving housing, and substantially limits the generation of vibrations by the rotating brush during the rotation of the latter. Therefore, the cleaning unit according to the present invention greatly limits the transfer of vibrations from the rotating brush to the main body of the suction head, and provides increased comfort of use for a user.

Selon un mode de réalisation de l'invention, l'au moins un organe de verrouillage est mobile par rapport au corps de bouchon selon une direction de déplacement qui s'étend transversalement à l'axe de rotation de la brosse rotative.According to one embodiment of the invention, the at least one locking member is movable relative to the cap body in a direction of movement which extends transversely to the axis of rotation of the rotary brush.

Selon un mode de réalisation de l'invention, la direction de déplacement de l'au moins un organe de verrouillage est sensiblement radiale par rapport à l'axe de rotation de la brosse rotative.According to one embodiment of the invention, the direction of movement of the at least one locking member is substantially radial relative to the axis of rotation of the rotating brush.

Selon un mode de réalisation de l'invention, la brosse rotative est configurée pour être montée de manière amovible dans un logement de réception selon une direction de montage qui s'étend transversalement, et de préférence perpendiculairement, à une direction de déplacement de la tête d'aspiration.According to one embodiment of the invention, the rotating brush is configured to be removably mounted in a receiving housing along a mounting direction which extends transversely, and preferably perpendicularly, to a direction of movement of the head suction.

Selon un mode de réalisation de l'invention, l'au moins un organe de verrouillage est un pêne de verrouillage.According to one embodiment of the invention, the at least one locking member is a locking bolt.

Selon un mode de réalisation de l'invention, l'axe de rotation de la brosse rotative est sensiblement confondu avec un axe central de la brosse rotative.According to one embodiment of the invention, the axis of rotation of the rotating brush is substantially coincident with a central axis of the rotating brush.

Selon un mode de réalisation de l'invention, l'au moins un organe de verrouillage est configuré pour faire saillie radialement d'une périphérie externe du corps de bouchon lorsque l'au moins un organe de verrouillage occupe la position de verrouillage.According to one embodiment of the invention, the at least one locking member is configured to project radially from an outer periphery of the cap body when the at least one locking member occupies the locking position.

Selon un mode de réalisation de l'invention, l'au moins un organe de verrouillage est configuré pour être situé en retrait de ou pour sensiblement affleurer la périphérie externe du corps de bouchon lorsque l'au moins un organe de verrouillage occupe la position de libération.According to one embodiment of the invention, the at least one locking member is configured to be set back from or to be substantially flush with the outer periphery of the cap body when the at least one locking member occupies the position of release.

Selon un mode de réalisation de l'invention, l'au moins un organe de verrouillage est monté coulissant par rapport au corps de bouchon.According to one embodiment of the invention, the at least one locking member is mounted to slide relative to the cap body.

Selon un mode de réalisation de l'invention, le bouchon de fermeture comporte un organe d'actionnement qui est configuré pour déplacer l'au moins un organe de verrouillage entre la position de verrouillage et la position de libération.According to one embodiment of the invention, the closure cap comprises an actuating member which is configured to move the at least one locking member between the locking position and the release position.

Selon un mode de réalisation de l'invention, l'organe d'actionnement est actionnable manuellement depuis l'extérieur de la tête d'aspiration lorsque le corps de bouchon est verrouillé sur le corps principal.According to one embodiment of the invention, the actuating member is manually operable from outside the suction head when the cap body is locked on the main body.

Selon un mode de réalisation de l'invention, l'organe d'actionnement est monté mobile par rapport au corps de bouchon entre une première position d'actionnement et une deuxième position d'actionnement, l'organe d'actionnement et l'au moins un organe de verrouillage étant configurés de telle sorte qu'un déplacement de l'organe d'actionnement de la première position d'actionnement à la deuxième position d'actionnement entraîne un déplacement de l'au moins un organe de verrouillage de la position de libération à la position de verrouillage et de telle sorte qu'un déplacement de l'organe d'actionnement de la deuxième position d'actionnement à la première position d'actionnement entraîne un déplacement de l'au moins un organe de verrouillage de la position de verrouillage à la position de libération. Une telle configuration du bouchon de fermeture permet un verrouillage/déverrouillage du corps de bouchon uniquement en déplaçant l'organe d'actionnement entre les première et deuxième positions d'actionnement, ce qui assure un retrait aisé et ergonomique de la brosse rotative hors du logement de réception.According to one embodiment of the invention, the actuating member is movably mounted relative to the plug body between a first actuating position and a second actuating position, the actuating member and the at least one locking member being configured such that a movement of the locking member actuation from the first actuation position to the second actuation position results in a displacement of the at least one locking member from the release position to the locking position and such that a displacement of the member actuation from the second actuation position to the first actuation position causes the at least one locking member to move from the locking position to the release position. Such a configuration of the closure plug allows locking/unlocking of the plug body only by moving the actuating member between the first and second actuating positions, which ensures easy and ergonomic removal of the rotating brush from the housing. reception.

Une telle configuration contribue aussi à assurer un verrouillage fiable indépendant de la force exercée par l'utilisateur pour verrouiller le bouchon de fermeture.Such a configuration also contributes to ensuring reliable locking independent of the force exerted by the user to lock the closure cap.
