L'organe de verrouillage 23 comporte plus particulièrement une première branche formant une partie de commande 24, une deuxième branche formant une partie de verrouillage 25, et une partie de liaison 26 qui est courbée, par exemple de manière sensiblement en arc de cercle, et qui relie la partie de commande 24 et la partie de verrouillage 25. De façon avantageuse, au moins la partie de verrouillage 25 est de forme allongée. Selon le mode de réalisation représenté sur les figures, la partie de commande 24 et la partie de verrouillage 25 sont chacune de forme allongée.The locking member 23 more particularly comprises a first branch forming a control part 24, a second branch forming a locking part 25, and a connecting part 26 which is curved, for example in a substantially circular arc, and which connects the control part 24 and the locking part 25. Advantageously, at least the locking part 25 is of elongate shape. According to the embodiment shown in the figures, the control part 24 and the locking part 25 are each of elongated shape.

La partie de commande 24 est montée coulissante sur le corps principal 4 selon une direction de coulissement D3 et entre une position inactive (voir la figure 5) et une position active. De façon avantageuse, la direction de coulissement D3 s'étend transversalement à la direction de retrait D2, et sensiblement verticalement lorsque la tête de nettoyage 2 repose sur une surface de support sensiblement horizontale.The control part 24 is slidably mounted on the main body 4 in a sliding direction D3 and between an inactive position (see figure 5 ) and an active position. Advantageously, the sliding direction D3 extends transversely to the retraction direction D2, and substantially vertically when the cleaning head 2 rests on a substantially horizontal support surface.

La partie de verrouillage 25 est mobile entre une position de verrouillage (voir la figure 5) dans laquelle la partie de verrouillage 25 coopère avec un élément de verrouillage 27 prévu sur l'élément de nettoyage 11, et par exemple sur le bouchon de fermeture 14, de manière à empêcher un retrait de l'élément de nettoyage 11 hors du logement de réception 9, et une position de libération dans laquelle la partie de verrouillage 25 libère l'élément de verrouillage 27 de manière à autoriser un retrait de l'élément de nettoyage 11 hors du logement de réception 9. L'élément de verrouillage 27 peut prendre différentes formes, et peut par exemple être formé par un logement de verrouillage, tel qu'une rainure de verrouillage, une butée de verrouillage ou encore un épaulement de verrouillage. De façon avantageuse, la partie de verrouillage 25 comporte une extrémité libre 25.1 qui est configurée pour coopérer avec l'élément de verrouillage 27 dans la position de verrouillage et pour se dégager de l'élément de verrouillage 27 dans la position de libération.The locking part 25 is movable between a locking position (see figure 5 ) in which the locking part 25 cooperates with a locking element 27 provided on the cleaning element 11, and for example on the closing plug 14, so as to prevent withdrawal of the cleaning element 11 from the housing receiving 9, and a release position in which the locking part 25 releases the locking element 27 so as to allow withdrawal of the cleaning element 11 from the receiving housing 9.

Advantageously, the locking part 25 comprises a free end 25.1 which is configured to cooperate with the locking element 27 in the locking position and to disengage from the locking element 27 in the release position.

Selon le mode de réalisation représenté sur les figures, la partie de commande 24 et la partie de verrouillage 25 sont inclinées l'une par rapport à l'autre d'un angle d'inclinaison, et l'organe de verrouillage 23 est configuré de telle sorte que l'angle d'inclinaison entre la partie de commande 24 et la partie de verrouillage 25 présente une première valeur lorsque la partie de verrouillage 25 occupe la position de verrouillage et une deuxième valeur lorsque la partie de verrouillage 25 occupe la position de libération, la deuxième valeur étant inférieure à la première valeur. Il en résulte que, lorsque la partie de verrouillage 25 passe de la position de verrouillage à la position de libération, son extrémité libre 25.1 se déplace en arc de cercle pour se dégager de l'élément de verrouillage 27 dans la position de libération. Dans l'exemple représenté aux figures, l'extrémité libre 25.1 de la partie de verrouillage 25 se déplace verticalement vers le haut entre la position de verrouillage et la position de libération.According to the embodiment shown in the figures, the control part 24 and the locking part 25 are inclined with respect to each other by an angle of inclination, and the locking member 23 is configured to such that the angle of inclination between the operating part 24 and the locking part 25 has a first value when the locking part 25 occupies the locking position and a second value when the locking part 25 occupies the locking position. release, the second value being less than the first value. As a result, when the locking portion 25 moves from the locking position to the release position, its free end 25.1 moves in an arc of a circle to disengage from the locking element 27 in the release position. In the example shown in the figures, the free end 25.1 of the locking part 25 moves vertically upwards between the locking position and the release position.

L'organe de verrouillage 23 est également configuré de telle sorte qu'un déplacement de la partie de commande 24 de la position inactive à la position active entraîne une déformation élastique de la partie de liaison 26 et un déplacement de la partie de verrouillage 25 de la position de verrouillage à la position de libération. De façon avantageuse, l'organe de verrouillage 23 est configuré pour solliciter élastiquement la partie de commande 24 vers la position inactive et la partie de verrouillage 25 vers la position de verrouillage, lorsque la partie de verrouillage 25 occupe la position de libération.The locking member 23 is also configured such that a movement of the control part 24 from the inactive position to the active position results in an elastic deformation of the connection part 26 and a movement of the locking part 25 of lock position to release position. Advantageously, the locking member 23 is configured to elastically urge the control part 24 towards the inactive position and the locking part 25 towards the locking position, when the locking part 25 occupies the released position.

Selon le mode de réalisation représenté sur les figures, la tête de nettoyage 2 comporte une butée d'appui 28 (voir la figure 5) prévue sur le corps principal 4 et contre laquelle prend appui la partie de verrouillage 25 lorsque la partie de commande 24 est déplacée de la position inactive à la position active. La butée d'appui 28 est plus particulièrement configurée pour entraîner la déformation élastique de la partie de liaison 26 lorsque la partie de commande 24 est déplacée de la position inactive à la position active.According to the embodiment shown in the figures, the cleaning head 2 comprises a bearing stop 28 (see figure 5 ) provided on the main body 4 and against which the locking part 25 bears when the control part 24 is moved from the inactive position to the active position. The support stop 28 is more particularly configured to cause the elastic deformation of the connecting part 26 when the control part 24 is moved from the inactive position to the active position.

Avantageusement, la butée d'appui 28 est disposée d'un côté de la partie de verrouillage 25 et la partie de commande 24, qui s'étend depuis la partie de liaison 26, est disposée de l'autre côté de la partie de verrouillage 25. Un tel agencement, permet à la partie de verrouillage 25 de basculer autour de la butée d'appui 28 lorsque la partie de commande 24 est déplacée, de préférence en translation, entre la position inactive et la position active. Dans cette configuration, la partie de liaison 26 qui est déformable élastiquement réalise avantageusement une fonction pivot et assure aussi un rappel élastique de la partie de commande 24 vers sa position inactive en l'absence de sollicitation sur la partie de commande 24.Advantageously, the support stop 28 is arranged on one side of the locking part 25 and the control part 24, which extends from the connecting part 26, is arranged on the other side of the locking part. 25. Such an arrangement allows the locking part 25 to swing around the support stop 28 when the control part 24 is moved, preferably in translation, between the inactive position and the active position. In this configuration, the connecting part 26 which is elastically deformable advantageously performs a pivot function and also provides an elastic return of the control part 24 to its inactive position in the absence of stress on the control part 24.

La butée d'appui 28 est configurée pour contacter la partie de verrouillage 25 au niveau du deuxième tiers de la longueur de la partie de verrouillage 25. Cette configuration permet de limiter les efforts nécessaires au déverrouillage tout en limitant l'encombrement interne que représente le mécanisme de verrouillage / déverrouillage comprenant l'organe de verrouillage 23 et la butée d'appui 28.The support stop 28 is configured to contact the locking part 25 at the level of the second third of the length of the locking part 25. This configuration makes it possible to limit the forces required for unlocking while limiting the internal bulk represented by the locking part. locking / unlocking mechanism comprising the locking member 23 and the support stop 28.

De préférence, la tête de nettoyage 2 et l'organe de verrouillage 23 sont conçus de telle sorte que, lors du déplacement de la partie de commande 24 de la position inactive à la position active, la partie de liaison 26 a une déformation élastique plus importante que la partie de verrouillage 25 et une déformation élastique plus importante que la partie de commande 24.Preferably, the cleaning head 2 and the locking member 23 are designed such that when moving the control part 24 from the inactive position to the active position, the connecting part 26 has a more elastic deformation. greater than the locking part 25 and a greater elastic deformation than the control part 24.

Lors du déplacement de la partie de commande 24 de la position inactive à la position active, la partie de commande 24 et la partie de verrouillage 25 subissent des déformations élastiques négligeables comparativement à celle de la partie de liaison 26. Autrement dit, la tête de nettoyage 2 et l'organe de verrouillage 23 sont conçus pour que ce soit la partie de liaison 26 qui se déforme en priorité lors du déplacement de la partie de commande 24 de la position inactive à la position active. Outre la présence de la butée d'appui 28, la déformation de la partie de liaison 26 peut être privilégiée en ajustant les formes et épaisseurs de la partie de commande 24, de la partie de verrouillage 25 et de la partie de liaison 26 de l'organe de verrouillage 23.When moving the control part 24 from the inactive position to the active position, the control part 24 and the locking part 25 undergo negligible elastic deformations compared to that of the connecting part 26. In other words, the head of cleaning 2 and the locking member 23 are designed so that it is the connecting part 26 which deforms as a priority when moving the control part 24 from the inactive position to the active position. In addition to the presence of the support stop 28, the deformation of the connecting part 26 can be favored by adjusting the shapes and thicknesses of the control part 24, of the locking part 25 and of the connecting part 26 of the 'locking member 23.
