Description

DISPOSITIF DE DIFFUSION D’UN FLUIDE ACTIF, NOTAMMENT D’UN FLUIDE DE TRAITEMENT D’ODEURS, À L’AIDE D’UN FLUX VECTEUR DEVICE FOR DIFFUSING AN ACTIVE FLUID, IN PARTICULAR AN ODOR TREATMENT FLUID, USING A VECTOR FLOW
[1] La présente invention concerne un dispositif de diffusion d'un fluide actif, notamment d’un fluide de traitement d’odeurs. Elle trouvera ses applications, par exemple, dans le domaine automobile. [1] The present invention relates to a device for diffusing an active fluid, in particular an odor treatment fluid. It will find its applications, for example, in the automotive field.
[2] Dans ce domaine, il est connu des diffuseurs permettant un écoulement du fluide actif dans l’habitacle d’un véhicule afin de le parfumer et/ou de masquer les mauvaises odeurs, ceci par entraînement à l’aide d’un flux vecteur, en particulier par un flux d’air. [2] In this field, it is known diffusers allowing a flow of the active fluid in the passenger compartment of a vehicle in order to perfume it and/or to mask bad odors, this by driving with the aid of a flow vector, in particular by an air flow.
[3] Cependant, les possibilités d’installation des diffuseurs disponibles selon cette technologie restent limitées. Cela oblige les fabricants de diffuseurs à multiplier leurs gammes de produit pour proposer des diffuseurs adaptés à différents supports. Cela oblige aussi les utilisateurs à employer plusieurs diffuseurs dans leur véhicule pour avoir un traitement de l’air qui soit approprié au cas d’espèce. [3] However, the installation possibilities of the diffusers available using this technology remain limited. This forces diffuser manufacturers to multiply their product ranges to offer diffusers adapted to different supports. This also forces users to use several diffusers in their vehicle to have an air treatment that is appropriate to the case in point.
[4] Un but de l’invention est de proposer un dispositif de diffusion qui pallie au moins en partie les inconvénients précédents. [4] An object of the invention is to provide a diffusion device which at least partially overcomes the above drawbacks.
[5] L’invention concerne de la sorte, selon un premier aspect, un dispositif de diffusion d'un fluide actif, ledit dispositif comprenant un boîtier définissant au moins un logement destiné à accueillir un matériau configuré pour libérer ledit fluide actif, ledit boîtier comprenant au moins deux jeux d’empreintes de fixation distinctes, chacun desdits jeux d’empreintes étant configuré pour permettre un positionnement différent du dispositif dans un flux vecteur d’entraînement dudit fluide actif. [5] The invention thus relates, according to a first aspect, to a device for diffusing an active fluid, said device comprising a housing defining at least one housing intended to receive a material configured to release said active fluid, said housing comprising at least two sets of distinct fixing cavities, each of said sets of cavities being configured to allow a different positioning of the device in a vector flow driving said active fluid.
[6] De la sorte, en plaçant le matériau libérant le fluide actif dans un boîtier et en munissant ledit boîtier de plusieurs jeux d’empreintes de fixation spécifiques, un même boîtier peut être utilisé dans différentes configurations, chaque configuration correspondant à un type de support et/ou de conditions d’utilisation donnés. Il n’est donc plus nécessaire de prévoir une multiplicité de diffuseurs intégrant ledit fluide actif, selon des caractéristiques distinctes, pour s’adapter à chaque cas de figures. [7] Selon des caractéristiques supplémentaires, qui pourront être mises en oeuvre indépendamment les unes des autres ou selon toutes les combinaisons techniquement possibles et qui forment autant de modes de réalisation de l’invention : [6] In this way, by placing the material releasing the active fluid in a housing and by providing said housing with several sets of specific fixing indentations, the same housing can be used in different configurations, each configuration corresponding to a type of given support and/or conditions of use. It is therefore no longer necessary to provide a multiplicity of diffusers integrating said active fluid, according to distinct characteristics, to adapt to each case.

[8] Chacun desdits jeux d’empreintes de fixation présente un intérêt propre et un dispositif de diffusion comprenant un boîtier muni de l’un seulement desdits jeux d’empreintes de fixation est également conforme à l’invention. [8] Each of said sets of fixing impressions has its own interest and a diffusion device comprising a housing provided with only one of said sets of fixing impressions is also in accordance with the invention.
[9] L’invention concerne de la sorte, selon un second aspect, un dispositif de diffusion d’un fluide actif, ledit dispositif comprenant un boîtier définissant un logement destiné à accueillir un matériau configuré pour libérer ledit fluide actif, ledit boîtier comprenant au moins un jeu d’empreintes de fixation permettant un positionnement du dispositif dans un flux vecteur d’entraînement dudit fluide actif, ledit jeu d’empreintes étant configuré pour coopérer avec support pour une fixation, notamment par encliquetage, sur ledit support à travers un substrat, notamment un filtre à air. [9] The invention thus relates, according to a second aspect, to a device for diffusing an active fluid, said device comprising a housing defining a housing intended to receive a material configured to release said active fluid, said housing comprising at at least one set of fixing cavities allowing the device to be positioned in a vector flow driving said active fluid, said set of cavities being configured to cooperate with a support for fixing, in particular by snap-fastening, to said support through a substrate , including an air filter.
[10] Dans une telle configuration, grâce à l’utilisation d’un boîtier contenant ledit le matériau configuré pour libérer le fluide à diffuser, l’invention permet d’utiliser un fluide actif qui ne permettrait pas son intégration directe dans le substrat. Il permet en outre d’utiliser le boîtier comme recharge de fluide actif ce qui permet de ne pas avoir à changer l’intégralité du substrat une fois le fluide actif épuisé. [10] In such a configuration, thanks to the use of a housing containing said material configured to release the fluid to be diffused, the invention makes it possible to use an active fluid which would not allow its direct integration into the substrate. It also allows the case to be used as an active fluid refill, which means that the entire substrate does not have to be changed once the active fluid has been used up.
[11] L’ invention concerne aussi, selon un troisième aspect, un dispositif de diffusion d’un fluide actif, ledit dispositif comprenant un boîtier définissant un logement destiné à accueillir un matériau configuré pour libérer ledit fluide actif, ledit boîtier comprenant au moins un jeu d’empreintes de fixation permettant un positionnement du dispositif dans un flux vecteur d’entraînement dudit fluide actif, ledit jeu d’empreintes comprenant une fente médiane ménagée sur ledit boîtier de sorte que ledit dispositif puisse être fixé transversalement à une paroi de séparation de deux conduits d’écoulement dudit flux vecteur. [11] The invention also relates, according to a third aspect, to a device for diffusing an active fluid, said device comprising a housing defining a housing intended to receive a material configured to release said active fluid, said housing comprising at least one set of fixing indentations allowing positioning of the device in a vector flow driving said active fluid, said set of indentations comprising a central slot provided on said housing so that said device can be fixed transversely to a partition wall of two flow ducts of said vector flow.
[12] Dans une telle configuration, grâce à l’extension du boîtier de part et d’autre de sa fente de fixation, l’invention permet au fluide actif d’être entraîné par un flux vecteur réparti dans différents conduits et donc d’éviter l’utilisation de diffuseurs dans chacun des conduits. [13] L’invention concerne encore, selon un quatrième aspect, un dispositif de diffusion d’un fluide actif, ledit dispositif comprenant un boîtier définissant un logement destiné à accueillir un matériau configuré pour libérer ledit fluide actif, ledit boîtier comprenant au moins un jeu d’empreintes de fixation permettant un positionnement du dispositif dans un flux vecteur d’entraînement dudit fluide actif, ledit jeu d’empreintes comprenant des formes d’articulation en rotation du boîtier dans un support destiné à former un capot d’ouverture/fermeture autorisant ou non la diffusion dudit fluide actif en dehors du boîtier, en fonction d’une position angulaire relative dudit boîtier et dudit capot. [12] In such a configuration, thanks to the extension of the housing on either side of its fixing slot, the invention allows the active fluid to be driven by a vector flow distributed in different ducts and therefore to avoid the use of diffusers in each of the ducts. [13] The invention also relates, according to a fourth aspect, to a device for diffusing an active fluid, said device comprising a housing defining a housing intended to receive a material configured to release said active fluid, said housing comprising at least one set of fixing indentations allowing positioning of the device in a vector flow driving said active fluid, said set of indentations comprising forms of articulation in rotation of the casing in a support intended to form an opening/closing cover authorizing or not the diffusion of said active fluid outside the housing, depending on a relative angular position of said housing and of said cover.
[14] Dans cette configuration, grâce au capot articulé coopérant avec le boîtier, l’invention permet de mieux contrôler la diffusion du fluide actif en pouvant ouvrir/fermer à volonté le boîtier. Ledit capot permet en outre d’envisager une fixation sur un grand nombre de supports divers. [14] In this configuration, thanks to the articulated cover cooperating with the housing, the invention makes it possible to better control the diffusion of the active fluid by being able to open/close the housing at will. Said cover also makes it possible to envisage fixing to a large number of various supports.
[15] D’autres caractéristiques, détails et avantages apparaîtront à la lecture de la description détaillée ci-après, et à l’analyse des dessins annexés, parmi lesquels : [15] Other characteristics, details and advantages will appear on reading the detailed description below, and on analyzing the appended drawings, including:
[16] La figure 1 est une vue en perspective d’un premier exemple de réalisation du dispositif conforme à l’invention, [16] Figure 1 is a perspective view of a first embodiment of the device according to the invention,
[17] La figure 2 est une vue en coupe transversale illustrant de façon schématique le dispositif de la figure 1 en utilisation sur un support, [17] Figure 2 is a cross-sectional view schematically illustrating the device of Figure 1 in use on a support,
[18] La figure 3 est une vue éclatée, en perspective, d’un deuxième exemple de réalisation du dispositif conforme à l’invention, [18] Figure 3 is an exploded view, in perspective, of a second embodiment of the device according to the invention,
[19] La figure 4 est une vue éclatée, en perspective, du dispositif de la figure 3 en utilisation sur un support, [19] Figure 4 is an exploded view, in perspective, of the device of Figure 3 in use on a support,
[20] La figure 5 est une vue éclatée, en perspective, d’un troisième exemple de réalisation de l’invention, [20] Figure 5 is an exploded view, in perspective, of a third embodiment of the invention,
[21] La figure 6 est une vue en perspective du dispositif de la figure 5, assemblé et placé dans une première configuration, [21] Figure 6 is a perspective view of the device of Figure 5, assembled and placed in a first configuration,
[22] La figure 7 est une vue en perspective du dispositif de la figure 5, assemblé et placé dans une deuxième configuration. [23] Comme illustré aux différentes figures, l’invention concerne un dispositif de diffusion d'un fluide actif. Elle trouvera ses applications, par exemple, dans le domaine automobile, notamment pour la diffusion du fluide actif dans un habitacle de véhicule. [22] Figure 7 is a perspective view of the device of Figure 5, assembled and placed in a second configuration. [23] As illustrated in the various figures, the invention relates to a device for distributing an active fluid. It will find its applications, for example, in the automotive field, in particular for the diffusion of the active fluid in a vehicle interior.
[24] Comme illustré aux figures 1 , 3 et 5, ledit dispositif comprend un boîtier 1 et une pluralité de billes 2 en un matériau configuré pour libérer ledit fluide actif sous forme gazeuse. Lesdites billes 2 sont illustrées à l’extérieur du boîtier car il s’agit d’une vue éclatée mais il est bien évident que, selon l’invention, elles se trouvent à l’intérieur dudit boîtier 1 . Pour cela ledit boîtier 1 définit au moins un logement accueillant lesdites billes 2. [24] As illustrated in Figures 1, 3 and 5, said device comprises a housing 1 and a plurality of balls 2 of a material configured to release said active fluid in gaseous form. Said balls 2 are illustrated outside the case because it is an exploded view but it is obvious that, according to the invention, they are inside said case 1. For this, said housing 1 defines at least one housing receiving said balls 2.
[25] Dans les exemples de réalisation illustrés, on remarque que l’ensemble formé par le boîtier 1 et les billes 2 qu’il contient est identique d’un exemple de réalisation à l’autre. Les avantages d’un tel mode de réalisation de l’invention seront détaillés plus bas. [25] In the illustrated embodiments, it is noted that the assembly formed by the housing 1 and the balls 2 that it contains is identical from one embodiment to another. The advantages of such an embodiment of the invention will be detailed below.
[26] Ledit boîtier 2 est configuré pour permettre un écoulement dudit fluide actif par mélange avec un flux vecteur balayant ledit dispositif. Ledit flux vecteur se décompose en un premier flux incident, illustré par les flèches repérées 4, et deuxième un flux, illustré par les flèches repérées 6, avec lequel le fluide actif sous forme gazeuse est mélangé. L’utilisation combinée des billes 2 permettant la libération du fluide actif sous forme gazeuse et du boîtier 1 permettant de configurer l’écoulement du flux vecteur, tout en contenant lesdites billes 2, permet de favoriser une bonne diffusion du fluide actif. [26] Said housing 2 is configured to allow a flow of said active fluid by mixing with a vector flow sweeping said device. Said vector flow breaks down into a first incident flow, illustrated by the arrows marked 4, and a second flow, illustrated by the arrows marked 6, with which the active fluid in gaseous form is mixed. The combined use of the balls 2 allowing the release of the active fluid in gaseous form and of the housing 1 making it possible to configure the flow of the vector flow, while containing said balls 2, makes it possible to promote good diffusion of the active fluid.
[27] Lesdites billes 2 présentent, par exemple, une forme sensiblement sphérique, ellipsoïdale et/ou cylindrique, notamment avec un diamètre compris entre 1 ,5 et 4 mm. [27] Said balls 2 have, for example, a substantially spherical, ellipsoidal and/or cylindrical shape, in particular with a diameter of between 1.5 and 4 mm.
[28] Elles sont formées, par exemple, d’un matériau polymère, préférentiellement d’un élastomère thermoplastique et encore plus préférentiellement d’un ou de copolymères séquencés constitués de blocs de polyamide rigides et de blocs de polyéther souples, notamment connu sous le nom commercial de PEBAX ®. En variante, il pourra s’agir, par exemple, d’EVA, de cellulose, de céramique, de coton et/ou de bois. [29] Ledit fluide actif comprend au moins une molécule volatile, voire est formé d’un matériau volatile. [28] They are formed, for example, of a polymer material, preferably of a thermoplastic elastomer and even more preferably of one or more block copolymers consisting of rigid polyamide blocks and flexible polyether blocks, in particular known as trade name of PEBAX ®. As a variant, it may be, for example, EVA, cellulose, ceramic, cotton and/or wood. [29] Said active fluid comprises at least one volatile molecule, or even is formed from a volatile material.
[30] Il s’agit, par exemple, d’un fluide de traitement d’odeurs tel qu’un fluide antiodeur ou formant une fragrance, dite blanche, c’est-à-dire ayant la capacité de réduire la perception de certaines odeurs, en particulier d’odeurs ressenties comme désagréables. Dans l’habitacle d’un véhicule, il pourra s’agir d’odeurs d’humidité ou de renfermé, de neuf, corporelle, de cigarettes, d’animaux, de nourriture ou autres. En variante, ledit fluide de traitement d’odeur est constitué d’une senteur permettant de désinfecter l’air, de réduire le mal des transports, ayant un effet énergisant, un effet d’alerte et/ou un effet calmant. Il peut encore s’agir d’une senteur d’aromathérapie et/ou d’un parfum. [30] This is, for example, an odor treatment fluid such as an anti-odor fluid or a so-called white fragrance-forming fluid, that is to say having the ability to reduce the perception of certain odors, in particular odors perceived as unpleasant. In the passenger compartment of a vehicle, there may be odors of damp or musty, new, bodily, cigarettes, animals, food or other. Alternatively, said odor treatment fluid consists of a scent for disinfecting the air, reducing motion sickness, having an energizing effect, a warning effect and/or a calming effect. It can also be an aromatherapy scent and/or a perfume.
[31] Ledit fluide actif est préférentiellement imprégné sous forme liquide dans lesdites billes. Il comprend, par exemple, moins de 35%, en poids, de solvant. [31] Said active fluid is preferably impregnated in liquid form in said balls. It comprises, for example, less than 35%, by weight, of solvent.
[32] La quantité de fluide actif est comprise entre 0,5 et 3 g, préférentiellement entre 1 ,25 et 2 g. Il représente, notamment, de 20 à 200%, voire de 40 à 60%, du matériau des billes, en poids. [32] The amount of active fluid is between 0.5 and 3 g, preferably between 1.25 and 2 g. It represents, in particular, from 20 to 200%, or even from 40 to 60%, of the material of the balls, by weight.
[33] Ledit flux vecteur est gazeux. Il s’agit, par exemple, d’un flux d’air. Il s’agit en particulier d’un flux d’air généré par un dispositif de chauffage, ventilation et conditionnement d’air de l’habitacle du véhicule, aussi connu sous l’acronyme HVAC, non-illustré. Un tel dispositif HVAC comprend un ou plusieurs pulseurs générant un flux d’air qui pourra être refroidi et/ou réchauffer à l’aide d’échangeurs de chaleur au niveau d’une chambre de traitement thermique dudit dispositif HVAC, ledit flux s’écoulant ensuite dans des conduits pour être diffusé au niveau d’aérateurs dans différentes directions, notamment en direction d’un pare-brise du véhicule et/ou en direction d’occupants du véhicule, plus spécialement leurs jambes et/ou leur visage. [33] Said carrier stream is gaseous. This is, for example, an airflow. This is in particular a flow of air generated by a heating, ventilation and air conditioning device for the passenger compartment of the vehicle, also known by the acronym HVAC, not shown. Such an HVAC device comprises one or more blowers generating a flow of air which can be cooled and/or heated using heat exchangers at the level of a heat treatment chamber of said HVAC device, said flow flowing then in conduits to be diffused at the level of aerators in different directions, in particular in the direction of a windshield of the vehicle and/or in the direction of the occupants of the vehicle, more especially their legs and/or their face.
[34] Il est à noter qu’un tel flux d’air présente un débit variable, dépendant de la demande de l’utilisateur, un tel débit pouvant être modulé en partant d’une valeur minimum correspondant à une vitesse d’environ 0,85 m/s. Une telle vitesse du flux d’air correspond généralement à une première position active du dispositif HVAC. [35] Préférentiellement, ledit boîtier 1 est configuré pour être balayé intérieurement et/ou extérieurement par ledit flux vecteur. [34] It should be noted that such an airflow has a variable flow, depending on the user's request, such a flow being able to be modulated starting from a minimum value corresponding to a speed of approximately 0 .85 m/s. Such a speed of the air flow generally corresponds to a first active position of the HVAC device. [35] Preferably, said housing 1 is configured to be swept internally and / or externally by said vector flow.
[36] Ledit flux vecteur pénètre de la sorte dans le logement accueillant les billes 2 et vient lécher chacune des billes 2. Ceci favorise la libération du fluide actif dans le logement du boîtier 1 , sous forme gazeuse, notamment par désorption. [36] Said vector flow penetrates in this way into the housing receiving the balls 2 and licks each of the balls 2. This promotes the release of the active fluid in the housing of the housing 1, in gaseous form, in particular by desorption.
[37] Ledit flux vecteur s’écoule aussi le long de faces externes du boîtier 2, en étant dévié par celui-ci, ce qui permet de provoquer un entraînement du fluide actif libéré sous forme gazeuse. [37] Said vector flow also flows along the outer faces of the housing 2, being deflected by the latter, which makes it possible to cause entrainment of the active fluid released in gaseous form.
[38] L’ efficacité d’un tel entraînement dépend de la nature, laminaire ou turbulent, de l’écoulement du flux vecteur autour du boîtier 1 . Pour un entraînement optimal, comme on l’a vu plus haut, ledit boîtier est configuré pour permettre un écoulement du flux vecteur qui provoque un mélange avec le fluide actif libéré sous forme gazeuse. [38] The effectiveness of such entrainment depends on the nature, laminar or turbulent, of the flow of the vector flux around the casing 1 . For optimal training, as seen above, said housing is configured to allow flow of the vector flow which causes mixing with the active fluid released in gaseous form.
[39] Plus précisément, ledit boîtier 1 est avantageusement dimensionné de sorte que l’écoulement dudit flux vecteur à l’extérieur du boîtier présente un nombre de Reynolds d’environ 1000. En effet, on se trouve alors, après l’obstacle constitué par le boîtier 1 , avec un écoulement plus instable présentant des caractéristiques se situant dans une zone de transition entre des écoulements présentant un sillage avec des vortex de Karman oscillants et des écoulements présentant des couches limites laminaire et un sillage turbulent large. [39] More specifically, said housing 1 is advantageously sized so that the flow of said vector flow outside the housing has a Reynolds number of approximately 1000. Indeed, we then find ourselves, after the obstacle constituted by the casing 1, with a more unstable flow having characteristics located in a transition zone between flows having a wake with oscillating Karman vortices and flows having laminar boundary layers and a wide turbulent wake.
[40] Pour cela, dans l’exemple illustré, ledit boîtier 1 s’étend selon un axe d’extension longitudinale X et il présente une section droite sensiblement circulaire le long d’une partie au moins dudit axe d’extension longitudinale. Plus précisément, il présente ici une section droite circulaire le long dudit axe d’extension longitudinale à l’exception de partie munies d’empreintes de fixation 12, 14, 16 qui seront détaillées plus bas. Ledit boîtier présente ainsi une forme globalement cylindrique. [40] For this, in the example shown, said housing 1 extends along an axis of longitudinal extension X and it has a substantially circular cross section along at least part of said axis of longitudinal extension. More specifically, it here has a circular cross section along said axis of longitudinal extension with the exception of parts provided with fixing indentations 12, 14, 16 which will be detailed below. Said housing thus has a generally cylindrical shape.
[41] Par ailleurs, en tenant compte, notamment, de la vitesse du flux d’air évoquée plus haut, ledit boîtier 1 présente préférentiellement un diamètre compris entre 14 et 22 mm, notamment de 18 mm. On obtient de la sorte un débit de diffusion optimum. [42] Pour assurer une diffusion d’une durée satisfaisante, on pourra jouer sur le nombre de billes. Lesdites billes 2 sont, par exemple, au nombre de 20 à 140. Pour un dispositif permettant une durée de diffusion supérieure à trois mois, avec une durée journalière d’utilisation d’environ une heure, lesdites billes 2 sont préférentiellement de 40 à 70. Ledit boîtier 2 présente alors une longueur comprise entre 70 et 80 mm, notamment de 75 mm, ce qui lui confère un encombrement qui reste réduit au regard de son efficacité. [41] Moreover, taking into account, in particular, the speed of the air flow mentioned above, said housing 1 preferably has a diameter of between 14 and 22 mm, in particular 18 mm. In this way, an optimum diffusion rate is obtained. [42] To ensure a diffusion of a satisfactory duration, one can play on the number of balls. Said balls 2 are, for example, 20 to 140 in number. Said box 2 then has a length of between 70 and 80 mm, in particular 75 mm, which gives it a size which remains small with regard to its effectiveness.
[43] Selon un autre aspect de l’invention, ledit boîtier 1 comprend une pluralité de fenêtres 8 de passage dudit fluide actif sous forme gazeuse. Lesdites fenêtres 8 s’étendent angulairement autour de l’axe d’extension longitudinale du boîtier et présentent de la sorte une forme allongée. [43] According to another aspect of the invention, said housing 1 comprises a plurality of windows 8 for passage of said active fluid in gaseous form. Said windows 8 extend angularly around the axis of longitudinal extension of the housing and thus have an elongated shape.
[44] Lesdites fenêtres 8 sont réparties en deux rangs diamétralement opposés. Un premier desdits rangs, non-visible sur les figures, permet au flux vecteur d’entrer dans le boîtier 1 , et un second 10 desdits rangs, permet au fluide actif libéré, sous forme gazeuse, par les billes 2 d’être entraîné par ledit flux vecteur. Lesdites fenêtres 8, en particulier lesdites fenêtres 8 d’un même rang, sont parallèles entre elles. [44] Said windows 8 are divided into two diametrically opposed rows. A first of said rows, not visible in the figures, allows the vector flow to enter the housing 1, and a second 10 of said rows, allows the active fluid released, in gaseous form, by the balls 2 to be driven by said vector flux. Said windows 8, in particular said windows 8 of the same row, are parallel to each other.
[45] Elles présentent une taille plus petite que la taille des billes afin d’éviter que celles-ci ne puissent sortir du boîtier une fois introduite dans leur logement. Lesdites fenêtres 8 présentent, par exemple, une longueur d’environ 6 mm et/ou une largeur d’environ 2 mm. Lesdites fenêtres 8 d’un même rang sont, notamment, au nombre de 20 à 25 et/ou espacées, notamment, d’environ 1 mm. [45] They are smaller than the size of the balls in order to prevent them from coming out of the case once introduced into their housing. Said windows 8 have, for example, a length of approximately 6 mm and/or a width of approximately 2 mm. Said windows 8 of the same row are, in particular, 20 to 25 in number and/or spaced apart, in particular, by approximately 1 mm.
[46] Tel que déjà évoqué plus haut, ledit boîtier 1 comprend par ailleurs au moins un jeu d’empreintes de fixation 12, 14, 16 permettant un positionnement du boîtier dans le flux vecteur. [46] As already mentioned above, said housing 1 also comprises at least one set of fixing indentations 12, 14, 16 allowing positioning of the housing in the vector flow.
[47] Chacun desdits jeux d’empreintes 12, 14, 16 est avantageusement configuré pour autoriser une fixation dudit boîtier 1 sur un support de sorte que ledit boîtier 1 soit orienté transversalement, notamment sensiblement perpendiculairement, à une direction incidente dudit flux vecteur. Ainsi, chacun desdits jeux d’empreintes 12, 14, 16 permet une fixation dudit boîtier 1 sur son support de sorte que lesdites fenêtres 8 soient orientées transversalement, notamment sensiblement perpendiculairement, à la direction incidente dudit flux vecteur. Une telle orientation des fenêtres 8 permet d’améliorer le bon mélange du fluide actif, sous forme gazeuse, dans le flux vecteur. [47] Each of said sets of indentations 12, 14, 16 is advantageously configured to allow said housing 1 to be fixed to a support so that said housing 1 is oriented transversely, in particular substantially perpendicularly, to an incident direction of said vector flow. Thus, each of said sets of indentations 12, 14, 16 allows said housing 1 to be fixed to its support so that said windows 8 are oriented transversely, in particular substantially perpendicularly, to the incident direction of said vector flux. Such an orientation of the windows 8 makes it possible to improve the good mixing of the active fluid, in gaseous form, in the vector flow.
[48] Selon les modes de réalisation illustrés, on constate que, selon un autre aspect de l’invention, ledit boîtier 1 comprend au moins deux, ici trois, jeux d’empreintes de fixation distinctes 12, 14, 16. [48] According to the illustrated embodiments, it can be seen that, according to another aspect of the invention, said housing 1 comprises at least two, here three, sets of distinct fixing indentations 12, 14, 16.
[49] Chacun desdits jeux d’empreintes 12, 14, 16 est configuré pour permettre un positionnement différent du boîtier 1 dans le flux vecteur d’entraînement dudit fluide actif. Avec un même boîtier 1 , le dispositif peut ainsi être fixé dans différentes configurations, comme cela est respectivement illustré aux figures 2, 4 ainsi que 6 et 7. Le dispositif de diffusion conforme à l’invention permet de la sorte d’être utilisé sur de multiples supports avec le même boîtier 1 . [49] Each of said sets of indentations 12, 14, 16 is configured to allow a different positioning of the housing 1 in the driving vector flow of said active fluid. With the same housing 1, the device can thus be fixed in different configurations, as shown respectively in Figures 2, 4 as well as 6 and 7. The diffusion device according to the invention thus allows it to be used on multiple media with the same enclosure 1 .
[50] Comme illustré par les figures 3 et 4, l’un 12 desdits jeux d’empreintes, dit premier jeu d’empreintes, est configuré pour coopérer avec un premier support 18 pour une fixation par encliquetage sur ledit premier support 18, à travers un substrat 20. [50] As illustrated by Figures 3 and 4, one 12 of said sets of prints, said first set of prints, is configured to cooperate with a first support 18 for attachment by snap-fastening on said first support 18, to through a substrate 20.
[51] Ledit substrat 20 est ici formé d’un filtre à air 22. Il s’agit en particulier d’un filtre à air destiné à être positionné au niveau d’une unité d’entrée d’air du dispositif HVAC évoqué plus haut. Ledit filtre à air 22 est formé d’un matériau, notamment fibreux, présentant des plis 24 parallèles. Ledit filtre 22 est fixé dans un cadre, non-illustré, lui-même rapporté à une armature dudit dispositif HVAC. Ledit boîtier 1 est configuré pour être situé dans l’un des plis 24 dudit filtre 22. [51] Said substrate 20 is here formed of an air filter 22. This is in particular an air filter intended to be positioned at an air inlet unit of the HVAC device mentioned more high. Said air filter 22 is formed of a material, in particular fibrous, having folds 24 parallel. Said filter 22 is fixed in a frame, not shown, itself attached to a frame of said HVAC device. Said box 1 is configured to be located in one of the pleats 24 of said filter 22.
[52] Ledit premier support 18 forme un crochet d’encliquetage. Le crochet présente ici une configuration en U. Il comprend une base 26 et deux bras 28 déformables élastiquement. Lesdits bras 28 sont symétriques. Ils s’étendent à partir de ladite base 26. Une extrémité libre desdits bras 28 comprend une déformation 30 formant une nervure d’encliquetage. Lesdits bras 28 sont configurés pour pouvoir passer à travers le filtre 22 qu’il transperce lors de la mise en place du dispositif de diffusion sur ledit filtre 22. [52] Said first support 18 forms a snap hook. The hook here has a U-shaped configuration. It comprises a base 26 and two elastically deformable arms 28. Said arms 28 are symmetrical. They extend from said base 26. A free end of said arms 28 includes a deformation 30 forming a latching rib. Said arms 28 are configured to be able to pass through the filter 22 which it pierces when the diffusion device is put in place on said filter 22.
[53] Ledit premier jeu d’empreintes 12 comprend au moins un, ici deux, premiers méplats 32, formés en surface dudit boîtier 1 pour définir une butée d’encliquetage ici par l’intermédiaire d’un bord 34 desdits premiers méplats 32, destiné à coopérer avec la déformation 30 des bras 28. [53] Said first set of cavities 12 comprises at least one, here two, first flats 32, formed on the surface of said housing 1 to define a latching abutment here via an edge 34 of said first flats 32, intended to cooperate with the deformation 30 of the arms 28.
[54] Lesdits premiers méplats 32 sont situés de part et d’autre desdits rangs de fenêtres 8. De la sorte, comme illustré, l’extension angulaire des fenêtres 8 se trouvant à leur niveau peut être identique à celle des autres fenêtres 8. Lesdits premiers méplats 32 sont parallèles audit axe d’extension longitudinale du boîtier 1 et/ou parallèles entre eux. Ils sont situés dans une partie médiane dudit boîtier 1 le long de son axe d’extension longitudinale. [54] Said first flats 32 are located on either side of said rows of windows 8. In this way, as shown, the angular extension of the windows 8 located at their level can be identical to that of the other windows 8. Said first flats 32 are parallel to said axis of longitudinal extension of housing 1 and/or parallel to each other. They are located in a middle part of said casing 1 along its axis of longitudinal extension.
[55] La mise en place du dispositif de diffusion sur le filtre 22 s’effectue de la façon suivante. Le boîtier 1 est positionné dans le pli choisi dudit filtre 22, d’un côté de celui-ci. Le crochet est placé de l’autre côté et ses bras 28 viennent transpercer le filtre 22 pour passer à travers ce dernier. Lesdits bras 28 s’écartent alors l’un de l’autre en passant au niveau des premiers méplats 32 puis se rapprochent une fois que leur déformation 30 a dépassé le bord 34 desdits premiers méplats 32. Lesdites déformations 30 sont alors en butée contre lesdits bords 34 et le boîtier 1 est bloqué dans le pli du filtre 22, le boîtier 1 étant encliqueté dans le crochet passant à travers ledit filtre 22. On aura en effet compris que la base 26 du crochet reste du côté du filtre 22 opposé à celui où se trouve le boîtier 1 . [55] The installation of the diffusion device on the filter 22 is carried out as follows. The box 1 is positioned in the chosen fold of said filter 22, on one side thereof. The hook is placed on the other side and its arms 28 pierce the filter 22 to pass through the latter. Said arms 28 then move away from each other passing at the level of the first flats 32 and then approach once their deformation 30 has exceeded the edge 34 of said first flats 32. Said deformations 30 are then in abutment against said edges 34 and the housing 1 is blocked in the fold of the filter 22, the housing 1 being snapped into the hook passing through said filter 22. It will in fact be understood that the base 26 of the hook remains on the side of the filter 22 opposite to that where is box 1.
[56] Comme illustré par les figures 1 et 2, l’un 14 desdits jeux d’empreintes, dit deuxième jeu d’empreintes, comprend une fente 36, médiane, ménagée sur ledit boîtier 1 de sorte que ledit dispositif puisse être fixé transversalement à une paroi 38 de séparation de deux conduits 40, 42 d’écoulement dudit flux vecteur. [56] As illustrated by Figures 1 and 2, one 14 of said sets of prints, said second set of prints, comprises a slot 36, median, provided on said housing 1 so that said device can be fixed transversely to a wall 38 separating two conduits 40, 42 for the flow of said vector flow.
[57] Il pourra s’agir de conduits du dispositif HVAC évoqué plus haut, par exemple de conduits situés entre son unité d’entrée d’air et la chambre de traitement thermique du flux d’air dudit dispositif HVAC ou encore de conduits de distribution dudit flux d’air en direction des aérateurs. [57] These may be ducts from the HVAC device mentioned above, for example ducts located between its air inlet unit and the heat treatment chamber for the air flow of said HVAC device or even ducts from distribution of said air flow towards the vents.
[58] On pourra noter que lesdits logements accueillant les billes 2 sont alors au nombre de deux, ladite fente 36 séparant lesdits logements. [58] It may be noted that said housings accommodating the balls 2 are then two in number, said slot 36 separating said housings.
[59] Ledit boîtier 1 comprend des parois transversales 44, fermant chacun desdits logements de part et d’autre de ladite fente 36. Un espacement entre lesdites parois transversales 44 est avantageusement prévu juste inférieur à une épaisseur de ladite paroi de séparation 28. La fixation du dispositif de diffusion sur ladite paroi 38 est ainsi obtenue par ajustement serré. [59] Said housing 1 comprises transverse walls 44, closing each of said housings on either side of said slot 36. A spacing between said transverse walls 44 is advantageously provided just less than a thickness of said partition wall 28. The attachment of the diffusion device to said wall 38 is thus obtained by tight fit.
[60] Ladite fente 36 présente un fond 45 formé par une paroi de butée, opposée à une partie ouverte par laquelle elle est destinée à être insérée dans la paroi 38. [60] Said slot 36 has a bottom 45 formed by an abutment wall, opposite an open part through which it is intended to be inserted into the wall 38.
[61] On constate que dans le mode de réalisation à plusieurs jeux d’empreintes illustré ici, ladite fente 36 débouche latéralement au niveau du ou des premiers méplats 32. [61] It can be seen that in the embodiment with several sets of indentations illustrated here, said slot 36 opens laterally at the level of the first flat(s) 32.
[62] La mise en place du dispositif de diffusion sur la paroi de séparation 38 s’effectue en se plaçant au niveau d’une extrémité débouchante desdits conduits 40, 42. Ledit dispositif de diffusion est positionné perpendiculairement à ladite paroi de séparation 38 et la fente 36 est insérée en force sur un bord libre de ladite paroi de séparation 38. Ledit boîtier 1 s’étend de la sorte en regard de chacun des conduits 40, 42 et le fluide actif peut ainsi être diffusé dans chacun d’eux sans avoir à multiplier le nombre de boîtiers. [62] The placement of the diffusion device on the dividing wall 38 is carried out by positioning itself at the level of an open end of said conduits 40, 42. Said diffusion device is positioned perpendicular to said dividing wall 38 and the slot 36 is inserted by force on a free edge of the said partition 38. The said casing 1 thus extends opposite each of the ducts 40, 42 and the active fluid can thus be diffused in each of them without having to multiply the number of enclosures.
[63] Comme illustré par les figures 5 à 7, l’un 16 desdits jeux d’empreintes, dit troisième jeu d’empreintes, comprend des formes d’articulation en rotation du boîtier 1 dans un capot 50 d’ouverture/fermeture autorisant ou non la diffusion dudit fluide de traitement d’odeurs en dehors du boîtier 1 en fonction d’une position angulaire relative dudit boîtier 1 et dudit capot 50. Un tel capot, en ouvrant et fermant le boîtier 1 , permet de mieux réguler la diffusion du fluide actif en évitant qu’elle ne dépende que du débit du flux vecteur. [63] As illustrated by Figures 5 to 7, one 16 of said sets of prints, said third set of prints, comprises forms of articulation in rotation of the housing 1 in a cover 50 of opening / closing allowing whether or not the diffusion of said odor treatment fluid outside the housing 1 as a function of a relative angular position of said housing 1 and of said cover 50. Such a cover, by opening and closing the housing 1, makes it possible to better regulate the diffusion of the active fluid, avoiding that it depends only on the flow rate of the vector flow.
[64] Ledit capot 50 est, par exemple, cylindrique de diamètre juste supérieur à celui du boîtier 1 . Ledit capot 50 présente un axe d’extension longitudinale confondu avec celui dudit boîtier 1. Ledit boîtier 1 est configuré pour pivoter autour dudit axe d’extension longitudinale, dans ledit capot 50, grâce audit troisième jeu d’empreintes 16. [64] Said cover 50 is, for example, cylindrical with a diameter just greater than that of the housing 1. Said cover 50 has an axis of longitudinal extension coincident with that of said housing 1. Said housing 1 is configured to pivot around said axis of longitudinal extension, in said cover 50, thanks to said third set of indentations 16.
[65] Ledit capot 50 comprend des lumières 52 de passage du flux vecteur. Elles sont destinées à laisser libre lesdites fenêtres 8 dans une configuration d’ouverture du dispositif de diffusion, autorisant la diffusion du fluide actif. [65] Said cover 50 comprises lights 52 for passing the vector flux. They are intended to leave said windows 8 free in an opening configuration of the diffusion device, allowing the diffusion of the active fluid.
[66] Lesdites lumières 52 sont orientées selon l’axe d’extension longitudinale dudit boîtier. Elles présentent une envergure angulaire sensiblement identique à celle desdites fenêtres 8 et/ou une longueur correspondant à celle desdits rangs de fenêtres 8. Elles sont au nombre de deux, diamétralement opposées, de sorte à pouvoir correspondre auxdits rangs de fenêtres 8 en configuration d’ouverture. Dans le mode de réalisation illustré, lesdites lumières 52 sont interrompues dans une partie médiane par des parties du capot 50, notamment de sorte à dissimuler la fente 36 du boîtier 1 . Lesdites parties du capot 50 interrompant lesdites lumières 52 pourront en outre obstruer une ou plusieurs des fenêtres se trouvant à proximité de ladite fente 36. [66] Said lights 52 are oriented along the axis of longitudinal extension of said housing. They have an angular span substantially identical to that of said windows 8 and/or a length corresponding to that of said rows of windows 8. They are two in number, diametrically opposed, so as to be able to correspond to said rows of windows 8 in the open configuration. In the illustrated embodiment, said slots 52 are interrupted in a central part by parts of the cover 50, in particular so as to conceal the slot 36 of the casing 1 . Said parts of the cover 50 interrupting said slots 52 may also obstruct one or more of the windows located close to said slot 36.
[67] Tel que cela est illustré à la figure 6, selon la position angulaire du boîtier 1 dans le capot 50, lesdites fenêtres 8 ne sont pas en vis-à-vis des lumières 52 et le dispositif de diffusion est dans une configuration fermée. [67] As shown in Figure 6, depending on the angular position of the housing 1 in the cover 50, said windows 8 are not vis-à-vis the lights 52 and the diffusion device is in a closed configuration .
[68] Tel que cela est illustré à la figure 7, après rotation d’un quart de tour du boîtier 1 par rapport au capot 50, lesdites fenêtres 8 sont désormais en vis-à-vis des lumières 52 et le dispositif de diffusion est dans la configuration ouverte. Il permet ainsi la diffusion du fluide actif par l’intermédiaire du flux vecteur. Dans cette configuration, on note que ledit flux vecteur balaie également le capot 50, intérieurement et/ou extérieurement. [68] As shown in Figure 7, after rotation of a quarter turn of the housing 1 relative to the cover 50, said windows 8 are now vis-à-vis the lights 52 and the diffusion device is in the open configuration. It thus allows the diffusion of the active fluid via the vector flow. In this configuration, it is noted that said vector flux also sweeps cover 50, internally and/or externally.
[69] Ledit capot 50 fait préférentiellement partie dudit dispositif de diffusion. Grâce audit capot 50 qui présentera éventuellement une configuration volontairement esthétique, ledit dispositif de diffusion pourra être proposé à un utilisateur final, comme produit à monter dans l’habitacle, alors que les deux modes de réalisation précédents du dispositif de diffusion conforme à l’invention ont plus vocation à être prémontés en véhicule par un professionnel. [69] Said cover 50 preferably forms part of said diffusion device. Thanks to said cover 50 which will optionally have a deliberately aesthetic configuration, said diffusion device can be offered to an end user, as a product to be mounted in the passenger compartment, whereas the two previous embodiments of the diffusion device according to the invention are more likely to be pre-assembled in the vehicle by a professional.
[70] Ledit dispositif comprend en outre ici un bouton 54 permettant un actionnement en rotation du boîtier 1 par rapport au capot 50. Ledit capot 50 présente un axe d’extension longitudinale confondu avec celui dudit boîtier 1 et il est situé dans le prolongement de l’une des extrémités longitudinales dudit boîtier 1 , dite proximale. Ledit bouton 54 permet de la sorte de faire pivoter ledit boîtier 1 autour dudit axe d’extension longitudinale. [71] Ledit bouton 54 est destiné à être actionné manuellement par un utilisateur. Il comprend éventuellement une nervure d’indexage 55 permettant de repérer les configurations d’ouverture/fermeture. [70] Said device further comprises here a button 54 allowing rotational actuation of the housing 1 relative to the cover 50. Said cover 50 has a longitudinal extension axis coinciding with that of said housing 1 and it is located in the extension of one of the longitudinal ends of said housing 1, called proximal. Said button 54 thus makes it possible to cause said casing 1 to pivot around said axis of longitudinal extension. [71] Said button 54 is intended to be operated manually by a user. It optionally includes an indexing rib 55 making it possible to locate the opening/closing configurations.
[72] Ledit troisième jeu d’empreintes 16 comprend, par exemple, une première nervure d’articulation 56 (mieux visible aux figures 1 et 3). Ladite nervure 56 est située ici à une extrémité longitudinale dudit boîtier 1 , dite distale, opposée à son extrémité proximale. [72] Said third set of indentations 16 comprises, for example, a first hinge rib 56 (best seen in Figures 1 and 3). Said rib 56 is located here at a longitudinal end of said housing 1, called distal, opposite its proximal end.
[73] Ledit troisième jeu d’empreinte 16 comprend en outre au moins un, ici deux, deuxièmes méplats 58 (mieux visible aux figures 1 et 3). Lesdits deuxièmes méplats 58 sont configurés pour coopérer avec des formes complémentaires 60, situées au niveau dudit bouton d’actionnement 54 pour autoriser un entraînement du boîtier 1 dans le capot 50 selon ladite articulation en rotation. [73] Said third set of impressions 16 further comprises at least one, here two, second flats 58 (better visible in Figures 1 and 3). Said second flats 58 are configured to cooperate with complementary shapes 60, located at the level of said actuating button 54 to allow the casing 1 to be driven into the cover 50 according to said articulation in rotation.
[74] Lesdits deuxièmes méplats 58 sont situés de part et d’autre desdits rangs de fenêtres 8. De la sorte, comme illustré, l’extension angulaire des fenêtres 8 se trouvant à leur niveau peut être identique à celle des autres fenêtres 8. Lesdits deuxièmes méplats 58 sont parallèles audit axe d’extension longitudinale du boîtier 1 et/ou parallèles entre eux. Lesdits deuxièmes méplats 58 sont ici parallèles aux premiers méplats 32. Le ou lesdits deuxièmes méplats 58 sont situés au niveau de ladite extrémité proximale du boîtier 1 . [74] Said second flats 58 are located on either side of said rows of windows 8. In this way, as shown, the angular extension of the windows 8 located at their level can be identical to that of the other windows 8. Said second flats 58 are parallel to said axis of longitudinal extension of case 1 and/or parallel to each other. Said second flats 58 are here parallel to first flats 32. Said second flat(s) 58 are located at said proximal end of housing 1 .
[75] Ledit capot 50 comprend en outre une deuxième nervure d’articulation 62. Elle est située à proximité d’une extrémité axiale ouverte dudit capot 50. Lesdites première et deuxième nervures d’articulation 56, 62 permettent le glissement en rotation du boîtier 1 dans le capot 50. [75] Said cover 50 further comprises a second hinge rib 62. It is located close to an open axial end of said cover 50. Said first and second hinge ribs 56, 62 allow the housing to slide in rotation 1 in the hood 50.
[76] Ledit bouton 54 comprend une nervure de butée axiale 64, destinée à coopérer avec le capot 50, en particulier ladite deuxième nervure d’articulation 62. Elle permet le blocage axial du bouton 52 dans le capot 50 et consécutivement le blocage axial du boîtier 1 dans le capot 50, tout en conservant le degré de liberté nécessaire à la rotation de l’un dans l’autre. [76] Said button 54 comprises an axial stop rib 64, intended to cooperate with the cover 50, in particular said second hinge rib 62. It allows the axial locking of the button 52 in the cover 50 and subsequently the axial locking of the housing 1 in cover 50, while retaining the degree of freedom necessary for the rotation of one into the other.
[77] Ledit bouton 54 comprend des saillies axiales 66, 68. Elles sont ici au nombre de deux, symétriquement opposées. Lesdites saillies axiales 66, 68 présentent lesdites formes complémentaires 60, notamment au niveau d’une face interne desdites saillies 66, 68, et/ou ladite nervure de butée axiale 64, notamment au niveau de l’une face externe desdites saillies. Lesdites faces internes des saillies axiales 66, 68 sont planes et/ou lesdites faces externes desdites saillies axiales 66, 68 sont arrondies. [77] Said button 54 comprises axial projections 66, 68. They are here two in number, symmetrically opposed. Said axial projections 66, 68 have said complementary shapes 60, in particular at the level of an internal face said projections 66, 68, and/or said axial abutment rib 64, in particular at the level of one external face of said projections. Said inner faces of the axial projections 66, 68 are flat and/or said outer faces of said axial projections 66, 68 are rounded.
[78] Ledit dispositif comprend en outre, éventuellement, un anneau 80, notamment métallique. Ledit anneau 80 est situé, par exemple, entre le capot 50 et ledit bouton 54 le long dudit axe d’extension longitudinale. Ledit anneau 80 permet un meilleur glissement en rotation du bouton 54 contre le capot 50. Il est aussi avantageusement à but esthétique. [78] Said device further comprises, optionally, a ring 80, in particular metal. Said ring 80 is located, for example, between cover 50 and said button 54 along said axis of longitudinal extension. Said ring 80 allows better sliding in rotation of button 54 against cover 50. It is also advantageously for aesthetic purposes.
[79] On peut noter que ledit boîtier 1 , ledit capot 50, ledit bouton 54 et/ou ledit anneau 80 sont coaxiaux. [79] It may be noted that said housing 1, said cover 50, said button 54 and/or said ring 80 are coaxial.
[80] Ledit capot 50 comprend en outre des moyens de fixation à un support. Il s’agit, par exemple, d’une pince 70. Ladite pince 70 est configurée pour être fixée à tout support tel que, notamment, une grille d’aérateur. Elle est rapportée, éventuellement de façon amovible, sur une embase 72 dudit capot. Ladite embase 72 forme, par exemple, l’une des parties du capot 50 interrompant lesdites lumières 52 dans leur partie médiane. [80] Said cover 50 further comprises means for attachment to a support. It is, for example, a clamp 70. Said clamp 70 is configured to be fixed to any support such as, in particular, an aerator grille. It is attached, optionally in a removable manner, to a base 72 of said cover. Said base 72 forms, for example, one of the parts of the cover 50 interrupting said slots 52 in their middle part.
[81] Cela étant, comme on l’aura compris, chacun desdits jeux d’empreintes de fixation 12, 14, 16 présente son intérêt propre et un dispositif de diffusion comprenant un boîtier 1 muni de l’un seulement desdits jeux d’empreintes de fixation est également conforme à l’invention. [81] This being the case, as will have been understood, each of said sets of fixing impressions 12, 14, 16 has its own interest and a diffusion device comprising a housing 1 provided with only one of said sets of impressions fixing is also in accordance with the invention.
[82] Il est à noter que lesdites billes 2 sont introduites dans le boîtier 1 , par exemple, par une ouverture située à l’une et/ou l’autre des extrémités longitudinale dudit boîtier 1 , lesdites ouvertures étant fermées après introductions desdites billes 2. [82] It should be noted that said balls 2 are introduced into the housing 1, for example, through an opening located at one and / or the other of the longitudinal ends of said housing 1, said openings being closed after introductions of said balls 2.
[83] Il est encore à noter que le boîtier 1 , chargé de billes 2, pourra être proposé seul. Il pourra encore être proposé avec le crochet d’encliquetage 18 et/ou avec les autres composants 50, 54, 80 dudit dispositif de diffusion dans son troisième exemple de réalisation, par exemple sous la forme d’un kit prêt au montage. [83] It should also be noted that the housing 1, loaded with balls 2, may be offered alone. It may also be offered with the latching hook 18 and/or with the other components 50, 54, 80 of said diffusion device in its third embodiment, for example in the form of a kit ready for assembly.
