DISPOSITIF DE DIFFUSION ET CARTOUCHE AMOVIBLE POUR  DIFFUSION DEVICE AND REMOVABLE CARTRIDGE FOR
LEDIT DISPOSITIF  LEDIT DEVICE
La présente invention concerne un dispositif de diffusion, en particulier pour véhicules automobiles, et une cartouche amovible pour un tel dispositif. The present invention relates to a diffusion device, in particular for motor vehicles, and a removable cartridge for such a device.
Une amélioration de la qualité de l'air d'un véhicule automobile est d'une importance primordiale pour un passager. Une meilleure qualité d'air implique non seulement une amélioration du confort du passager mais peut également avoir des répercussions sur la santé du passager. Différents dispositif de diffusion permettant un traitement de l'air de la cabine de véhicule existent. Ces derniers peuvent être directement reliés au système de ventilation, de chauffage ou de climatisation mais ils peuvent également être des dispositifs indépendants des systèmes préexistants tels que ceux cités ci- dessus. Dans ce cas, ils sont souvent dissimulés sous la planche de bord, par exemple dans une boîte à gants ou vide-poche. L'air traité, ou parfumé, ressort par une grille de ventilation pouvant être fixée sur la planche de bord ou ailleurs. An improvement of the air quality of a motor vehicle is of paramount importance for a passenger. Better air quality not only improves passenger comfort but can also affect the health of the passenger. Different diffusion device for an air treatment of the vehicle cabin exist. These can be directly connected to the ventilation, heating or air conditioning system but they can also be devices independent of pre-existing systems such as those mentioned above. In this case, they are often hidden under the dashboard, for example in a glove box or empty-pocket. The treated air, or perfumed, comes out of a ventilation grille that can be fixed on the dashboard or elsewhere.
De tels dispositifs sont pourvus d'un système permettant d'y insérer des cartouches comprenant un agent volatil. Ces cartouches sont amovibles et sont généralement changées lorsque la cartouche ne contient plus d'agent volatil. Such devices are provided with a system for inserting cartridges comprising a volatile agent. These cartridges are removable and are usually changed when the cartridge no longer contains volatile agent.
Afin d'assurer une bonne exploitation de la cartouche, il est avantageux que le dispositif de diffusion soit contrôlé par une unité de traitement. Le déposant a mis en évidence que différents problèmes se posent alors. Il est tout d'abord préférable que l'unité de traitement soit informée de la présence de la cartouche. En effet, si l'unité de traitement tente de contrôler la cartouche alors que celle-ci est absente, ceci peut amener à des disfonctionnement. Pour améliorer l'impression de confort, le déposant a également mis en évidence qu'il est intéressant de pouvoir utiliser différents types de cartouches. Pour assurer un contrôle approprié de la cartouche utilisée, il est alors préférable que l'unité de traitement soit informée du type de cartouche mis en place. In order to ensure good exploitation of the cartridge, it is advantageous for the diffusion device to be controlled by a processing unit. The applicant has pointed out that different problems then arise. It is first preferable that the processing unit is informed of the presence of the cartridge. Indeed, if the processing unit tries to control the cartridge while it is absent, this can lead to malfunction. To improve the impression of comfort, the applicant has also highlighted that it is interesting to use different types of cartridges. To ensure proper control of the cartridge used, it is then preferable that the processing unit is informed of the type of cartridge set up.
Dans ce cadre, l'invention propose un dispositif de diffusion, en particulier pour véhicules automobiles, ledit dispositif comprenant un logement pour une cartouche amovible, contenant un ou une pluralité d'agents volatils, notamment des fragrances, ledit logement étant configuré pour recevoir ladite cartouche, dans une position d'utilisation, et permettre l'extraction de ladite cartouche hors dudit dispositif, ledit dispositif comprenant un système d'identification de ladite cartouche. In this context, the invention proposes a diffusion device, in particular for motor vehicles, said device comprising a housing for a removable cartridge, containing one or a plurality of volatile agents, in particular fragrances, said housing being configured to receive said cartridge, in a position of use, and allow extraction of said cartridge out of said device, said device comprising a system for identifying said cartridge.
L'invention permet de la sorte de s'assurer de la présence, voire du type de cartouche employée, en particulier en vue de son contrôle. In this way, the invention makes it possible to ascertain the presence, or even the type of cartridge used, in particular with a view to its control.
On entend par système d'identification un système permettant d'établir une reconnaissance de la cartouche comme, par exemple, un système permettant de déterminer la provenance de la cartouche et/ou la nature du ou des agents volatiles. By identification system is meant a system for establishing a recognition of the cartridge such as, for example, a system for determining the origin of the cartridge and / or the nature of the volatile agent (s).
Selon un aspect de l'invention, ledit système comprend au moins un ou des commutateurs, aptes à être actionnés par un ou des pions de ladite cartouche lorsque cette dernière est en position d'utilisation. Une telle solution est particulièrement attractive par sa simplicité et sa robustesse. Elle permet en effet d'éviter d'avoir à munir la cartouche d'éléments complexe d'identification, notamment d'éléments d'identification dont le fonctionnement ne conviendrait pas à un environnement automobile dont on sait qu'il est soumis à de fortes vibrations et à de nombreux champs électromagnétiques. According to one aspect of the invention, said system comprises at least one or switches, able to be actuated by one or more pins of said cartridge when the latter is in use position. Such a solution is particularly attractive for its simplicity and robustness. It makes it possible to avoid having to provide the cartridge with complex identification elements, in particular identification elements the operation of which would not be suitable for an automobile environment which is known to be subject to strong vibrations and many electromagnetic fields.
Il est en particulier à noter qu'un tel système d'identification et la cartouche associée pourront être utilisés dans d'autres dispositifs que des dispositifs de diffusion sans sortir du cadre de l'invention. In particular, it should be noted that such an identification system and the associated cartridge may be used in other devices than broadcasting devices without departing from the scope of the invention.

Comme illustré sur la figure 1 , l'invention concerne un dispositif de diffusion ou diffuseur permettant le traitement d'un flux d'air à l'aide d'un ou plusieurs agents volatils, notamment des fragrances. Elle est en particulier destinée à équiper des véhicules automobiles. As illustrated in Figure 1, the invention relates to a diffusion device or diffuser for the treatment of an air flow with one or more volatile agents, including fragrances. It is particularly intended to equip motor vehicles.
Selon un mode de réalisation particulièrement avantageux de l'invention, les agents volatils, notamment les fragrances, comprennent un substrat, notamment des billes, chargé en composé(s) volatil(s). Il pourra en particulier s'agir de billes odorantes. According to a particularly advantageous embodiment of the invention, the volatile agents, in particular the fragrances, comprise a substrate, in particular beads, loaded with volatile compound (s). It may in particular be fragrant beads.
Le diffuseur est illustré sur cette figure dans son ensemble. Il comprend ici un boîtier 100 sur lequel deux orifices servent d'entrée 105 et de sortie 1 10 de l'air. Dès lors, le boîtier sert de guide d'air et comprend une pluralité de composants qui vont permettre à l'air de circuler dans le boîtier. De préférence, une interface sur les orifices 105, 1 10 permet à une tubulure, non représentée, de s'y fixer tout en assurant l'étanchéité du système à l'air. Le diffuseur conforme à l'invention comprend un logement 10 pour une cartouche 130, amovible, contenant le ou les agents volatils. Ledit logement 10 est configuré pour recevoir ladite cartouche, dans une position d'utilisation, et permettre l'extraction de ladite cartouche hors dudit dispositif, The diffuser is illustrated in this figure as a whole. It comprises here a housing 100 on which two orifices serve as inlet 105 and outlet 1 10 of the air. Therefore, the housing serves as an air guide and includes a plurality of components that will allow air to flow into the housing. Preferably, an interface on the orifices 105, 1 10 allows a tubing, not shown, to be attached while ensuring the airtightness of the system. The diffuser according to the invention comprises a housing 10 for a cartridge 130, removable, containing the volatile agent or agents. said housing 10 is configured to receive said cartridge, in a position of use, and allow extraction of said cartridge from said device,
Selon un premier mode de réalisation de l'invention la cartouche comprend un seul agent volatil. Dans ce cas, il est nécessaire de changer la cartouche si l'on souhaite changer d'agent. According to a first embodiment of the invention the cartridge comprises a single volatile agent. In this case, it is necessary to change the cartridge if you want to change the agent.
Selon un autre mode de réalisation, la cartouche comprend plusieurs agents. L'invention permet avantageusement alors de changer d'agents sans changer de cartouche. According to another embodiment, the cartridge comprises several agents. The invention advantageously makes it possible to change agents without changing the cartridge.
Ledit dispositif comprend ici pour cela un sélecteur, qui pourra être logés dans ledit boîtier 100. Le sélecteur comprend, par exemple, un sélecteur d'entrée 125a, un sélecteur de sortie 125b et un axe mobile 135 les entraînant. Ledit diffuseur comprend en outre ici un mécanisme d'actionnement 150, permettant un entraînement dudit axe 135. Said device comprises for this purpose a selector, which may be housed in said housing 100. The selector comprises, for example, an input selector 125a, an output selector 125b and a movable axis 135 driving them. Said diffuser further comprises here an actuating mechanism 150, allowing a drive of said axis 135.
Le boîtier 100 peut être fixé à différents emplacements du véhicule, de préférence sur la planche de bord ou dans la boîte à gants afin que ce dernier soit facilement accessible au passager. En effet, il est avantageux que le passager puisse facilement changer la cartouche. The housing 100 can be attached to different locations of the vehicle, preferably on the dashboard or in the glove box so that it is easily accessible to the passenger. Indeed, it is advantageous that the passenger can easily change the cartridge.
La sortie d'air du boîtier 1 10 est reliée, par exemple, à une grille par laquelle l'air traité ou parfumé sort. Cette grille peut être fixée à différents emplacements dans le véhicule. De préférence, elle est située sur la planche de bord ou près des systèmes de ventilation du pare-brise, la grille étant reliée à la sortie du boîtier par la tubulure déjà évoquée. The air outlet of the housing 1 10 is connected, for example, to a grid through which the treated or perfumed air comes out. This grid can be attached to different locations in the vehicle. Preferably, it is located on the dashboard or near the ventilation systems of the windshield, the gate being connected to the outlet of the housing by the tubing already mentioned.
Ici, le boîtier 100 comprend une base 180, par exemple parallélépipède rectangle. Dans la base sont logés un pulseur 1 15 situé au- dessus de l'entrée 105 du boîtier et au moins une partie du mécanisme d'actionnement 150. Ledit mécanisme d'actionnement pourra comprendre un moteur 140. Ce dernier est fixé sur le boîtier 100 au-dessus du pulseur 1 15, et se trouve en dehors du boîtier. Au-dessus de la base 180, et à côté du moteur 140, une seconde partie du boîtier 170 possède une forme sensiblement cubique pour y loger le sélecteur de fragrances et la cartouche 130. Ces parties du boîtier sont assemblées pour n'en former qu'une seule. L'étanchéité à l'air est assurée dans l'ensemble du boîtier. L'orifice d'entrée 105 est donc dans la base du boîtier 180, sur la face inférieure et en dessous du pulseur 1 15. L'orifice de sortie 1 10 est sur la face supérieure de la deuxième partie 170, au-dessus du sélecteur de sortie 125b. Here, the housing 100 comprises a base 180, for example a rectangular parallelepiped. In the base are housed a pulser 1 15 located above the inlet 105 of the housing and at least a part of the mechanism 150. Said actuation mechanism may comprise a motor 140. The latter is fixed on the housing 100 above the blower 1 15, and is outside the housing. Above the base 180, and next to the motor 140, a second portion of the housing 170 has a substantially cubic shape for accommodating the fragrance selector and the cartridge 130. These housing parts are assembled to form only one part. 'only one. Airtightness is ensured throughout the housing. The inlet orifice 105 is therefore in the base of the housing 180, on the lower face and below the blower 1 15. The outlet orifice 1 10 is on the upper face of the second portion 170, above the 125b output selector.
L'air pénètre dans le boîtier par l'orifice d'entrée 105, en étant aspiré par le pulseur 1 15. Ce pulseur génère le flux d'air qui va finalement sortir du boîtier par l'orifice de sortie 1 10 après avoir traversé la cartouche 130. Le flux d'air est illustré par la ligne 120 sur la figure 1 . De préférence, le pulseur 1 15 est de type radial, mais il peut également être de type axial. The air enters the housing through the inlet port 105, being sucked by the blower 1 15. This blower generates the flow of air that will finally exit the housing through the outlet port 1 10 after crossing the cartridge 130. The air flow is illustrated by the line 120 in FIG. Preferably, the blower 1 is of radial type, but it can also be of axial type.
Ici, la cartouche 130 est composée d'une pluralité de cavités dans lesquelles différentes fragrances peuvent être logées. L'agent volatil, notamment la fragrance, contenu dans chacune des cavités pourra comporter un seul ou un mélange de composés chimiques, naturels et/ou artificiels, destinés à traiter, notamment à parfumer, le flux d'air. Here, the cartridge 130 is composed of a plurality of cavities in which different fragrances can be accommodated. The volatile agent, in particular the fragrance, contained in each of the cavities may comprise a single or a mixture of chemical compounds, natural and / or artificial, intended to treat, including perfume, the air flow.
Le sélecteur 125a, 125b est configuré de sorte que l'une ou plusieurs de ces cavités soient traversées par le flux d'air afin que celui-ci soit chargé des composés volatils de la ou des fragrances sélectionnées. Autrement dit, lorsque le flux d'air traverse la ou lesdites cavités sélectionnées, l'air vient en contact avec l'ensemble du substrat contenu dans chacune desdites cavités et ledit substrat libère le ou les composés qui vont parfumer et/ou traiter le flux d'air, et ensuite l'habitacle du véhicule automobile. Pour cela, le flux d'air 120 pénètre dans la cartouche 130 par une entrée du sélecteur d'entrée. Le flux d'air traverse alors la cartouche 130 de part en part en passant par l'une ou plusieurs des cavités de ladite cartouche qu'il quitte à travers une sortie dudit sélecteur de sortie 125b. En faisant traverser la ou les cavités sélectionnées par le flux d'air, on s'assure d'un chargement optimisé du flux d'air par la fragrance, celui-ci venant au contact de l'ensemble de la surface du substrat associé. Après être sortie de la cartouche, le flux d'air est ici guidé jusqu'à l'orifice de sortie 1 10 du boîtier. De manière préférentielle, le pulseur 1 15 permet au dispositif d'être indépendant du système de ventilation, de climatisation ou de chauffage dont le véhicule est éventuellement équipé. Il peut dès lors être utilisé indépendamment de ces systèmes, ce qui le rend d'autant plus flexible à l'utilisation. Dans un autre mode de réalisation de la présente invention, il est relié au système de ventilation, de climatisation ou de chauffage du véhicule. L'orifice d'entrée 105 et de sortie 1 10 seraient dans ce mode de réalisation relié à un conduit dudit système. The selector 125a, 125b is configured so that one or more of these cavities are traversed by the air flow so that it is loaded with the volatile compounds of the selected fragrance or fragrances. In other words, when the flow of air passes through said selected cavity or cavities, the air comes into contact with the entire substrate contained in each of said cavities and said substrate releases the compound (s) that will perfume and / or treat the flow. air, and then the passenger compartment of the motor vehicle. For this, the air flow 120 enters the cartridge 130 through an inlet of the input selector. The air flow then passes through the cartridge 130 through one or more of the cavities of said cartridge that it leaves through an outlet of said output selector 125b. By passing through the cavity or cavities selected by the air flow, it ensures an optimized loading of the air flow by the fragrance, the latter coming into contact with the entire surface of the associated substrate. After leaving the cartridge, the air flow is guided here to the outlet port 1 10 of the housing. Preferably, the blower 1 15 allows the device to be independent of the ventilation system, air conditioning or heating of which the vehicle is possibly equipped. It can therefore be used independently of these systems, which makes it all the more flexible to use. In another embodiment of the present invention, it is connected to the ventilation system, air conditioning or heating of the vehicle. In this embodiment, the inlet port 105 and the outlet port 1 10 would be connected to a conduit of said system.
La figure 2 offre une vue plus détaillée de la figure 1 sans le boîtier 100. La figure 2 illustre les détails du mécanisme d'actionnement 150, de l'axe mobile 135 et du sélecteur d'entrée 125a et de sortie 125b. La cartouche 130 est illustrée plus en détails sur la figure 3. Figure 2 provides a more detailed view of Figure 1 without the housing 100. Figure 2 illustrates the details of the actuating mechanism 150, the movable axis 135 and the input selector 125a and 125b output. The cartridge 130 is illustrated in greater detail in FIG.
Le mécanisme d'actionnement 150 comprend par exemple outre le moteur 140, un arbre 220, un pignon de transmission 230, permettant avantageusement une démultiplication, et un pignon droit 240. Le moteur 140 entraîne les éléments situés en aval : l'arbre 220, directement relié à un actuateur du moteur, entraîne le pignon de transmission 230, qui entraîne le pignon droit 240. L'axe mobile 135 est directement fixé sur le pignon droit 240 et est dès lors également entraîné par ce dernier. Avantageusement, le sélecteur d'entrée 125a et le sélecteur de sortie 125b se présentent sous la forme de plateaux tournants, l'axe mobile 135 perçant les deux plateaux tournants en leur centre. La forme du trou perçant les plateaux tournants correspond à la forme d'une section de l'axe mobile, de préférence de forme carrée de telle sorte que lorsque l'axe mobile tourne, les plateaux tournants tournent également. Les plateaux tournants sont séparés par une distance correspondant à la hauteur de la cartouche 130 afin de permettre à la cartouche d'y être insérée. Lorsque la cartouche est insérée entre les deux plateaux, ces derniers sont avantageusement pressés contre la cartouche par des ressorts, non illustrés, afin d'assurer l'étanchéité à l'air. The actuating mechanism 150 comprises, for example, in addition to the motor 140, a shaft 220, a transmission pinion 230 advantageously allowing reduction, and a pinion 240. The motor 140 drives the downstream elements: the shaft 220, directly connected to an actuator motor, drives the transmission pinion 230, which drives the pinion 240. The movable axis 135 is directly attached to the pinion 240 and is therefore also driven by the latter. Advantageously, the input selector 125a and the output selector 125b are in the form of rotating plates, the movable axis 135 piercing the two rotating plates at their center. The shape of the hole piercing the rotating plates corresponds to the shape of a section of the movable axis, preferably of square shape so that when the movable axis rotates, the rotating plates also rotate. The turntables are separated by a distance corresponding to the height of the cartridge 130 to allow the cartridge to be inserted. When the cartridge is inserted between the two plates, the latter are advantageously pressed against the cartridge by springs, not shown, to ensure airtightness.
De préférence, l'entrée et la sortie du flux d'air sur les plateaux tournants situés respectivement en amont et en aval de la cartouche se présentent sous la forme d'ouvertures débouchantes 260b (l'ouverture 260a en amont de la cartouche n'est pas visible) dont la taille est comparable à celle d'une entrée, respectivement d'une sortie d'air, d'une cavité de la cartouche. Les ouvertures des deux plateaux tournants sont disposées en vis- à-vis de manière à assurer la continuité du flux d'air. D'autre part, les positions des ouvertures desdits plateaux tournants restent synchronisées pendant leur mouvement grâce à l'axe mobile 135 qui les relie. Preferably, the inlet and the outlet of the air flow on the rotating plates located respectively upstream and downstream of the cartridge are in the form of through openings 260b (the opening 260a upstream of the cartridge n ' is not visible) whose size is comparable to that of an inlet, respectively an air outlet, a cavity of the cartridge. The openings of the two rotating plates are arranged vis-à-vis so as to ensure the continuity of the air flow. On the other hand, the positions of the openings of said rotating plates remain synchronized during their movement through the movable axis 135 which connects them.
La figure 3 offre une vue de la cartouche isolée 130. Avantageusement, la cartouche 130 est un élément amovible par rapport au boîtier 100. Le passager du véhicule peut alors facilement changer de cartouche, notamment lorsqu'elle est vide, la durée de vie d'une cartouche étant d'environ 3 mois pour une utilisation normale. Par « vide », on entend dont les fragrances sont épuisées et ne libèrent plus de composés volatils. FIG. 3 provides a view of the insulated cartridge 130. Advantageously, the cartridge 130 is a removable element relative to the casing 100. The passenger of the vehicle can then easily change the cartridge, especially when it is empty, the service life a cartridge being approximately 3 months for normal use. By "vacuum" is meant the fragrances are exhausted and no longer release volatile compounds.
La cartouche est ici munie d'une façade d'introduction 310 dans ledit boîtier, se présentant de manière similaire à la façade d'un tiroir. Cette façade 310 facilite l'insertion de ladite cartouche 130 dans le boîtier 100, selon une direction d'introduction I. La cartouche 130 est également pourvue d'une nervure longitudinale 315 de guidage située le long des trois faces verticales qui vont s'insérer dans le boîtier 100. Pour accueillir lesdites nervures de guidage 315 de la cartouche 130, le boîtier possède également des rainures de guidage 160, illustrées sur la figure 1 , de part et d'autre du logement de la cartouche dans le boîtier et au-dessus du plateau tournant inférieur 125a. The cartridge is here provided with an introduction facade 310 in said housing, which is similar to the front of a drawer. This facade 310 facilitates the insertion of said cartridge 130 into the housing 100, according to a direction of introduction I. The cartridge 130 is also provided with a longitudinal guide rib 315 located along the three vertical faces which will fit into the casing 100. To accommodate said guide ribs 315 of the cartridge 130, the The housing also has guide grooves 160, shown in Figure 1, on either side of the cartridge housing in the housing and above the lower turntable 125a.
Une fente 320 permet le passage de l'axe lorsque la cartouche est insérée dans le boîtier entre les deux plateaux tournants 125a et 125b illustrés aux figures 1 et 2. En position d'utilisation, l'axe mobile 135 se trouve au centre de la cartouche dans le fond de la fente. A slot 320 allows the passage of the axis when the cartridge is inserted into the housing between the two turntables 125a and 125b illustrated in Figures 1 and 2. In the position of use, the movable axis 135 is in the center of the cartridge in the bottom of the slot.
La cartouche comprend un corps 360 et un couvercle 350 dont la forme est parallélépipédique et la base est sensiblement carrée. Le corps est compartimenté pour définir lesdites cavités, le fond dudit corps comprend les entrées du flux d'air desdites cavités, et le couvercle comprend les sorties du flux d'air desdites cavités. La cartouche est de préférence en matière plastique. Lesdites ouvertures pourront être revêtues d'un grillage ou d'un film poreux pour retenir le substrat desdites fragrances tout en laissant passer le flux d'air à travers. The cartridge comprises a body 360 and a lid 350 whose parallelepipedal shape and the base is substantially square. The body is compartmentalized to define said cavities, the bottom of said body comprises the air flow inlets of said cavities, and the cover comprises the airflow outlets of said cavities. The cartridge is preferably made of plastic. Said openings may be coated with a mesh or a porous film to retain the substrate of said fragrances while allowing the flow of air through.
Avantageusement, des cavités occupées par une fragrance et des cavités vides alternent. L'alternance de cavités vides et de cavités logeant une fragrance permet de passer de chacune des cavités comprenant un fragrance à une cavité n'en comportant pas, sans passer par une cavité comprenant une autre fragrance. Advantageously, cavities occupied by a fragrance and empty cavities alternate. The alternation of empty cavities and cavities housing a fragrance makes it possible to go from each of the cavities comprising a fragrance to a cavity that does not include one, without going through a cavity comprising another fragrance.
Dans un mode de réalisation de la présente invention tel qu'illustré sur la figure 3, les différentes cavités de la cartouche et leurs ouvertures respectives forment des portions angulaires d'un anneau. Dans ce mode de réalisation particulièrement avantageux, cinq cavités sont prévues, dont trois pour loger une fragrance 340a, 340c, 340e et deux sont laissées vides intentionnellement 340b, 340d. L'angle balayé par les ouvertures de chaque portion angulaire est dans ce mode de réalisation légèrement inférieur à 60 degrés. Dans un tel mode de réalisation, les ouvertures 260a, 260b des plateaux se présentent également sous la forme d'une portion angulaire, chaque plateau comprenant ici une unique ouverture 260a, respectivement 260b. In one embodiment of the present invention as illustrated in Figure 3, the different cavities of the cartridge and their respective apertures form angular portions of a ring. In this particularly advantageous embodiment, five cavities are provided, of which three to house a fragrance 340a, 340c, 340e and two are intentionally left empty 340b, 340d. The angle swept by the apertures of each angular portion is in this embodiment slightly less than 60 degrees. In such an embodiment, the openings 260a, 260b of the trays are also in the form of an angular portion, each plate here comprising a single opening 260a, respectively 260b.
Le passager peut dès lors choisir entre trois fragrances différentes selon ses goûts : différentes ambiances sont envisageables pendant le voyage, ce qui peut être particulièrement agréable pour les longs voyages. Ces différentes fragrances peuvent également être très utiles pour masquer ou filtrer une odeur indésirable de tabac par exemple. Le passager peut également choisir de laisser le système de ventilation en marche sans pour autant être en présence d'une fragrance. The passenger can choose between three different fragrances according to his tastes: different moods are possible during the trip, which can be particularly pleasant for long trips. These different fragrances can also be very useful to mask or filter an unwanted smell of tobacco for example. The passenger can also choose to leave the ventilation system running without being in the presence of a fragrance.
Une telle distribution des cavités, sous la forme de portions angulaires en anneau, permet de facilement augmenter le nombre de cavités sans pour autant devoir modifier le mécanisme d'actionnement associé. Le seul changement à effectuer pour augmenter le nombre de fragrances disponibles au passager réside dans la taille des cavités de la cartouche et dans la taille des ouvertures des plateaux tournants qui leur correspondent. Such a distribution of the cavities, in the form of angular portions ring, can easily increase the number of cavities without having to change the associated actuating mechanism. The only change to be made to increase the number of fragrances available to the passenger is the size of the cavities of the cartridge and the size of the apertures of the rotating plates that correspond to them.
Les figures 4a à 4e illustrent une vue du haut du mécanisme permettant le changement de fragrances effectué par l'ensemble comprenant la cartouche 130 et le sélecteur 125a, 125b. La figure ne montre que le plateau tournant 125b situé sur la cartouche 130. Cependant, la vue du bas serait représentée de la même manière. L'axe mobile 135 ainsi que la fente 320 de la cartouche 130 sont également visibles sur la figure. Dans le mode de réalisation de la présente invention décrit à la figure 3, où la cartouche comprend cinq cavités dont trois sont dédiées à loger une fragrance et deux sont laissées vides, les figures 4a à 4e illustrent le passage de l'ouverture 260b de la plaque tournante 125b sur chacune des cinq positions. La figure 4a illustre la première position de la plaque tournante où la fragrance libérée provient de la cavité 340a de la figure 3. Pour passer à la deuxième position, illustrée sur la figure 4b, la plaque tournante va tourner dans le sens antihoraire d'un angle d'environ 60 degrés. Cette position correspond à une cavité vide de la cartouche correspondant à la cavité 340b de la figure 3. La figure 4c illustre l'effet d'une rotation supplémentaire dans le sens antihoraire d'environ 60 degrés par rapport à la deuxième position permettant de libérer la deuxième fragrance logée dans la cavité 340c. De la même manière, les figures 4d et 4e illustrent l'ouverture du plateau tournant située respectivement sur les cavités 340d pour le quatrième position et 340e pour la cinquième position de la cartouche. Figures 4a to 4e illustrate a top view of the mechanism for the change of fragrance performed by the assembly comprising the cartridge 130 and the selector 125a, 125b. The figure shows only the turntable 125b located on the cartridge 130. However, the bottom view would be shown in the same way. The movable axis 135 and the slot 320 of the cartridge 130 are also visible in the figure. In the embodiment of the present invention described in Figure 3, where the cartridge comprises five cavities, three of which are dedicated to house a fragrance and two are left empty, Figures 4a to 4e illustrate the passage of the opening 260b of the turntable 125b on each of the five positions. FIG. 4a illustrates the first position of the turntable where the released fragrance comes from the cavity 340a of FIG. 3. To move to the second position, illustrated in FIG. 4b, the turntable will turn counterclockwise of a angle of about 60 degrees. This position corresponds to an empty cavity of the cartridge corresponding to the cavity 340b of FIG. 3. FIG. 4c illustrates the effect of an additional rotation in the counterclockwise direction of about 60 degrees with respect to the second position allowing to release the second fragrance housed in the cavity 340c. In the same way, Figures 4d and 4e illustrate the opening of the turntable located respectively on the cavities 340d for the fourth position and 340th for the fifth position of the cartridge.
Préférentiellement, pour passer à une position ultérieure, la plaque tournante va tourner dans le sens horaire. En effet, il y a une zone par laquelle la plaque tournante ne passe pas pendant son utilisation. Cette zone se trouve au-dessus de la fente 320, ou entre les cavités 340a et 340e. Preferably, to move to a later position, the turntable will rotate clockwise. Indeed, there is an area through which the turntable does not pass during its use. This zone is located above the slot 320, or between the cavities 340a and 340e.
L'alternance de cavités vides et de cavités logeant une fragrance permet au passager de régler l'intensité de la fragrance diffusée par un actionnement du sélecteur en va-et-vient. Dans le même but, il est également possible de placer l'ouverture du plateau tournant en une position intermédiaire entre la cavité vide et la cavité remplie. Lorsque l'ouverture recouvre en totalité l'ouverture de la cavité, alors la diffusion est totale, lorsque l'ouverture recouvre seulement une partie de l'ouverture de la cavité comportant l'agent volatil, alors la diffusion n'est que partielle. Dans une mode de réalisation préféré de l'invention, la vitesse du plateau tournant pour passer d'une fragrance à une utilisation sans fragrance est de 0.5 seconde. Par suite, la vitesse de transition pour passer de la première position à la cinquième position, et vice-versa, est de 2.5 secondes. The alternation of empty cavities and cavities housing a fragrance allows the passenger to adjust the intensity of the fragrance diffused by an actuation of the selector back and forth. For the same purpose, it is also possible to place the opening of the turntable in an intermediate position between the empty cavity and the filled cavity. When the opening completely covers the opening of the cavity, then the diffusion is total, when the opening covers only part of the opening of the cavity comprising the volatile agent, then the diffusion is only partial. In a preferred embodiment of the invention, the speed of the turntable from a fragrance to a use without fragrance is 0.5 seconds. As a result, the transition speed to move from the first position to the fifth position, and vice versa, is 2.5 seconds.
Ce changement rapide entre différentes positions est rendu possible grâce au mécanisme d'actionnement 140 illustré sur les figures 1 et 2, et déjà décrit en partie. Dans un mode de réalisation préféré, le moteur 140 est de type moto- réducteur pas à pas. Ce type de moteur standard est choisi pour des raisons de coût et de disponibilité sur le marché. Comme illustré sur les figures 1 et 2, l'arbre et le pignon de transmission sont à portion angulaire. En effet, la plage de rotation des plateaux tournants n'est pas de 360°, mais de 240° comme discuté ci-dessus. This rapid change between different positions is made possible by the actuating mechanism 140 illustrated in Figures 1 and 2, and already described in part. In a preferred embodiment, the motor 140 is of the stepper motor reducer type. This type of standard engine is chosen for reasons of cost and availability on the market. As illustrated in Figures 1 and 2, the shaft and the transmission pinion are angular portion. Indeed, the rotation range of the rotating plates is not 360 °, but 240 ° as discussed above.
C'est la combinaison de l'arbre 220, du pignon de transmission 230 et du pignon droit 240 qui permet une démultiplication du mouvement induit par le moto-réducteur 210 de telle sorte que le sélecteur passe d'une position à la suivante en 0.5 secondes et de la première position à la cinquième position en 2.5 secondes, et vice-versa. La combinaison de ces trois éléments forme un organe de démultiplication qui permet d'obtenir de telles performances avec un moteur standard. Un système de commande du dispositif conforme à l'invention pourra comprendre un module de programmation et l'électronique associée afin de permettre au passager de contrôler le pulseur et le moteur du mécanisme d'actionnement électrique. Préférentiellement, le passager peut contrôler le distributeur de fragrances à partir d'une commande au volant. Le système de commande permet au conducteur de mettre le distributeur de fragrances sous tension, de choisir l'intensité de la fragrance diffusée, de choisir le débit du flux d'air diffusé et/ou de choisir la fragrance. Avantageusement, le système de commande indique lorsqu'une fragrance de la cartouche est vide. It is the combination of the shaft 220, the transmission pinion 230 and the right gear 240 which allows a reduction in the movement induced by the geared motor 210 so that the selector switches from one position to the next in 0.5 seconds and from the first position to the fifth position in 2.5 seconds, and vice versa. The combination of these three elements forms a gearing member that achieves such performance with a standard engine. A control system of the device according to the invention may include a programming module and the associated electronics to allow the passenger to control the blower and the motor of the electric actuation mechanism. Preferably, the passenger can control the fragrance dispenser from a steering wheel control. The control system allows the driver to turn on the fragrance dispenser, select the intensity of the fragrance dispensed, select the flow rate of the airflow and / or select the fragrance. Advantageously, the control system indicates when a fragrance of the cartridge is empty.
Dans un premier temps, le système de commande permet au passager de choisir la fragrance qu'il souhaite diffuser. Ensuite, il peut également régler le débit du flux d'air généré par le pulseur. Le système de commande permet également au passager de régler l'intensité de la fragrance qu'il souhaite diffuser. At first, the control system allows the passenger to choose the fragrance he wants to broadcast. Then, it can also adjust the air flow rate generated by the blower. The control system also allows the passenger to adjust the intensity of the fragrance he wants to broadcast.
Dans un mode de réalisation de la présente invention, le système de commande permet au passager de préprogrammer une séquence de diffusion qu'il souhaite en choisissant une durée de diffusion, une fragrance et son intensité. L'intensité pourra également varier au cours du temps ; il est dès lors possible de commencer par une diffusion totale qui devient partielle au cours du temps. Le système de commande permet également de choisir une fréquence de diffusion. Par exemple, le passager peut choisir de diffuser une certaine fragrance pendant une durée choisie, et puis ne rien diffuser pendant une autre durée. In one embodiment of the present invention, the control system allows the passenger to preprogram a desired broadcast sequence by choosing a diffusion duration, a fragrance and its intensity. The intensity may also vary over time; it is therefore possible to begin with a total diffusion that becomes partial over time. The control system also makes it possible to choose a broadcast frequency. For example, the passenger may choose to broadcast a certain fragrance for a chosen period of time, and then not broadcast for another period.
Si l'on se reporte de nouveau à la figure 1 , on constate que, selon l'invention, ledit diffuseur comprend un système 400 d'identification de ladite cartouche 130. Il permet de la sorte de s'assurer de la présence de ladite cartouche ainsi que, éventuellement, de son type, lorsque des cartouches contenant un ou des agents volatils différents sont utilisées On favorise de la sorte un bon fonctionnement dudit système de commande. Avantageusement, ledit système d'identification 400 comprend un ou des commutateurs 402, notamment électrique, aptes à être actionnés par un ou des pions 404 de ladite cartouche 130, lorsque cette dernière est en position d'utilisation. Lesdits commutateurs 402 et lesdits pions 404 sont, par exemple, présents en même nombre et associés par paire. Ils sont ici au nombre de trois, ce qui permet une identification de neuf cartouches différentes, en fonction du nombre de pions présents, la présence d'au moins un pion étant préférable. L'utilisation de tels moyens d'identification, essentiellement mécaniques, permet de disposer d'une solution particulièrement robuste et fiable. Le ou lesdits commutateurs 402 sont préférentiellement configurés pour se fermer sous l'effet d'une pression exercée par le ou lesdits pions 404, lors de l'introduction de ladite cartouche 130, lorsque celle-ci est correctement positionnée, et/ou s'ouvrir en absence de ladite pression. Ils fonctionnent par exemple pour cela par effet ressort de sorte à rester ouvert sous ledit effet, en absence de la pression exercée par les pions 404. Lesdits commutateurs présentent ici en ce sens une partie fixe et une partie mobile par rapport à ladite partie fixe, la partie mobile venant au contact de la partie fixe sous ledit effet ressort pour établir le contact électrique recherché. Ledit système d'identification pourra en outre comprendre un circuit imprimé 406, formé d'un substrat présentant des pistes de conductions électriques, par exemple un circuit imprimé de type FR4. Le ou lesdits commutateurs 402 sont fixés sur ledit substrat et électriquement connectés auxdites pistes. Ledit circuit imprimé 406 est ici sensiblement orienté orthogonalement à la direction d'introduction I de la cartouche. Il est fixé sur un support 407 présentant la même orientation. Referring back to FIG. 1, it can be seen that, according to the invention, said diffuser comprises a system 400 for identifying said cartridge 130. In this way, it makes it possible to ascertain the presence of said cartridge and, if appropriate, of its type, when cartridges containing one or more volatile agents are used. In this way, a good operation of said control system is promoted. Advantageously, said identification system 400 comprises one or more switches 402, in particular electrical, capable of being actuated by a or pins 404 of said cartridge 130, when the latter is in the use position. Said switches 402 and said pins 404 are, for example, present in the same number and associated in pairs. There are three of them, which allows identification of nine different cartridges, depending on the number of pions present, the presence of at least one pion being preferable. The use of such identification means, essentially mechanical, provides a particularly robust and reliable solution. The at least one switch 402 is preferably configured to close under the effect of a pressure exerted by the at least one pin 404, during the insertion of said cartridge 130, when the latter is correctly positioned, and / or open in the absence of said pressure. They operate for example for this purpose by spring effect so as to remain open under said effect, in the absence of the pressure exerted by the pins 404. Said switches here have in this sense a fixed part and a movable part with respect to said fixed part, the moving part coming into contact with the fixed part under said spring effect to establish the desired electrical contact. Said identification system may further comprise a printed circuit 406 formed of a substrate having electrical conduction tracks, for example a FR4 type printed circuit. The at least one switch 402 is attached to said substrate and electrically connected to said tracks. Said printed circuit 406 is here substantially oriented orthogonally to the insertion direction I of the cartridge. It is fixed on a support 407 having the same orientation.
Une unité de traitement, non représentée, dudit système d'identification est avantageusement configurée pour recevoir un signal dépendant d'un état fermé ou ouvert du ou desdits commutateurs 402. Ladite unité de traitement est préférentiellement distante, par exemple intégré dans ledit système de commande. A processing unit, not shown, of said identification system is advantageously configured to receive a signal depending on a closed or open state of said one or more switches 402. Said processing unit is preferably distant, for example integrated in said control system.
Ledit système d'identification comprend ici un câble de liaison 408 entre l'unité de traitement et les commutateurs 402, plus précisément entre l'unité de traitement et un connecteur, non-visible, lié aux pistes de conduction du circuit imprimé 406. Said identification system here comprises a connection cable 408 between the processing unit and the switches 402, more precisely between the processing unit and a non-visible connector connected to the conduction tracks of the printed circuit 406.
Lesdits commutateurs 402, comme les pions 404, sont préférentiellement disposés les uns à côté des autres, en une rangée, comme ici, ou en plusieurs rangées parallèles, ceci avec d'éventuels emplacement libres de pions en fonction de la cartouche à identifier. Said switches 402, like the pins 404, are preferably arranged next to each other, in a row, as here, or in several parallel rows, this with possible locations free of pins depending on the cartridge to be identified.
Lesdits pions 404 sont, par exemple, issus de matière. Ici, l'un des pions est issu du couvercle 350 et les deux autres de corps 360 de ladite cartouche 130. Ils s'étendent préférentiellement selon ladite direction d'introduction I de la cartouche. Ils présentent, par exemple, une forme cylindrique ou légèrement pyramidale, de section sensiblement carrée. Said pins 404 are, for example, made from material. Here, one of the pins comes from the cover 350 and the other two bodies 360 of said cartridge 130. They preferably extend in said direction of introduction I of the cartridge. They have, for example, a cylindrical or slightly pyramidal shape, of substantially square section.
