    [0008] BRIEF DESCRIPTION OF THE DRAWINGS The object, object and feature of the present invention and its advantages will become more clearly apparent from the following description of the preferred embodiments of the at least one volatile agent diffusion device according to the invention. , with reference to the drawings in which: FIG. 1 shows, in an exploded and schematic view, a device for diffusing at least one volatile agent, according to one embodiment of the present invention, FIG. schematically, a device for diffusing at least one volatile agent, comprising an actuator and selection means, said selection means and the actuator being coaxial, FIG. 3 shows in particular, schematically, a broadcasting device of at least one volatile agent, comprising an actuator, selection means and gear elements, FIG. 4 represents in particular, schematically 1, a device for diffusing at least one volatile agent comprising an actuator, selection means and a connecting belt, FIG. 5 shows, in a view from above and in a schematic manner, a reservoir provided with a plurality of cavities for storing a determined quantity of volatile agent, and FIG. 6 represents an embodiment of the selection means according to the invention.
    [0009] Figure 1 shows a schematic view of a device for diffusing at least one volatile agent 1. The diffusion device 1 comprises a housing 10 adapted to receive within it various components, described below. The housing 10 is provided with an opening (not shown) used for an air inlet to allow air to enter the interior of the diffusion device of at least one volatile agent 1, and an outlet air 6 to let out the air outside the diffusion device of at least one volatile agent 1. The opening is formed by an opening in the upper wall of the housing or in a side wall of the housing. The air outlet 6 is formed by means of an opening in the upper wall of said housing 10. Alternatively, the air outlet 61 may be formed on a side wall of the housing 10 according to the desired use of the diffusion device 1. The device for diffusing at least one volatile agent 1 comprises a fan 2, disposed inside the casing 10, adapted to generate a flow of air flowing from the air intake towards the of the air outlet 6. The device for diffusing at least one volatile agent 1 comprises, within the housing 10, a reservoir 4 adapted to store a determined quantity of one or more volatile agents, in particular one or more fragrances . According to one embodiment, the removable reservoir 4 comprises a diffusion element adapted to store and diffuse a determined quantity of one or more volatile agents. Thus, the tank 4 can be removed and replaced by another tank of the same type, for example when the contents of said tank 4 are exhausted, or said tank 4 can be filled with a new amount of volatile agent. One possible form of the tank 4 according to the present invention is shown in more detail with reference to FIG.
    [0010] The device for diffusing at least one volatile agent 1, within the housing 10, comprises selection means 3, 5, each provided with an opening 31, 51, adapted to allow the flow of air to flow through openings 31, 51. The selection means 3, 5 comprise a longitudinal axis of rotation 62 of the diffusion device 1. The operation of the selection means 3, 5 is described in detail with reference to FIGS. 5 and 6. 3, 5, are connected to the axis of rotation 62. Thus, the selection means 3, 5, are simultaneously rotated, so that the opening 31 present in the selection means 3 is aligned with the opening 51 present in the selection means 5. The various components, that is to say the fan 2, the selection means 3, 5 and the tank 4 are positioned one above the other according to a stack shown in FIGS. 1, 2, 3 and 4 and along an axis d stack 60 to obtain a minimized volume of the diffusion device of at least one volatile agent 1.
    [0011] The order of the components within the stack can vary according to the desired use of the diffusion device 1. Thus, alternatively, the fan 2 can be positioned downstream of the tank 4.
    [0012] In order to obtain a minimum compactness of the diffusion device 1, the output of the fan 2 can be in direct contact with the inlet of the tank 4 when the fan 2 is positioned upstream of the tank 4. Similarly, the outlet of the tank 4 can be in direct contact with the inlet of the fan 2 when the tank 2 is positioned upstream of the fan 2.
    [0013] The stack of the fan 2, selection means 3, 5 and the tank 4 around the stacking axis 60 makes it possible to obtain an air flow whose trajectory is perpendicular to the planes in which respectively the reservoir 4 and the fan 2. Preferably, the path of the air flow can deviate from the axis of rotation 60 at an angle between 00 and 45 °. The air intake and the air outlet can be positioned along the stacking axis 60 in order to obtain an air flow whose trajectory is substantially rectilinear with respect to the tank 4 and the fan 2, between the air inlet and air outlet. Alternatively, the air inlet and / or the air outlet can be positioned on a side wall of the housing 10. The stack of the tank 4, the fan 2 and the selection means 3, 5 allows partly to improve the compactness of the diffusion device 1 and, secondly, to limit the pressure losses of the air flow circulating within the diffusion device 1, in particular before the tank 4 passes through the flow of air. Thus, advantageously, the use of the diffusion device 1 makes it possible to optimally diffuse at least one volatile agent or to reduce the power of the fan 2 necessary for the circulation of an air flow in the diffusion device 1 .
    [0014] FIG. 2 represents a device for diffusing at least one volatile agent 11 which comprises the same components and the same architecture as those of the device for broadcasting at least one volatile agent 1 according to FIG. 1. The fan 2 is used in order to to create a flow of air through the tank 4 by using the circulation channel imposed by the openings 31, 51 of the selection means 3, 5. The device for diffusing at least one volatile agent 11, according to FIG. , comprises an actuator 7 centered on the axis of rotation 60 of the selection means 3, 5, for selecting the optimum position of said selection means 3, 5 with respect to the reservoir 4. For example, the actuator 7 can be a stepper motor or a DC motor. An alternative embodiment, shown in FIG. 3, shows a device for diffusing at least one volatile agent 21 that comprises the same components as those for the device for diffusing at least one volatile agent 10 according to FIG. device for diffusing at least one volatile agent 21 shows an actuator 17 positioned to be in contact with the circumference of the selection means 3, 5 by means of a gear device comprising gear elements 18, 19. such positioning of the actuator 17 near the reservoir 4 imposes a height of the diffusion device of at least one volatile agent 21 lower than that of the diffusion device of at least one volatile agent 11 of FIG. embodiment of alternative embodiment, shown in Figure 4, shows a device for diffusing at least one volatile agent 31 which comprises the same components as those of the device for diffusing at least one volatile agent 10 according to the figurative 1. The device for diffusing at least one volatile agent 31 comprises an actuator 27 provided with at least one connecting belt 28 that can exert a force on the selection means 3, 5 in order to drive said selection means 3 5 in rotation when the actuator 27 is rotated. As for the embodiment shown in FIG. 3, the embodiment according to FIG. 4 shows that the height of the diffusion device of at least one volatile agent 31 is relatively smaller than that of the diffusion device of FIG. at least one volatile agent 11 according to FIG.
    [0015] FIG. 5 represents, in a view from above, an embodiment of a reservoir 4 for storing a determined quantity of volatile agent. The tank 4 is provided with a body 40 in which a slot 41 is present, said slot 41 allowing the insertion of said tank 4 inside the device for the diffusion of at least one volatile agent 1, 11, 21, 31 , as shown with reference to FIGS. 1 to 4. The slot 41 is necessary to allow the passage of the axis of rotation 62 of the selection means 3, 5 within the tank 4, as shown in FIG. 6 The reservoir 4 comprises one or more cavities. In a particular example, the reservoir 4 comprises a plurality of cavities 42, 43, 44 for receiving each a specific amount of volatile agent. In FIG. 5, the cavities 42, 43, 44 are provided with one or more grids 45, 55 between which it is possible to position a diffusion element such as a bag containing a determined quantity of balls. The thickness of the grids 45, 55 is relatively small, that is to say that the grids 45, 55 represent a barrier that can be crossed by the flow of air flowing through the tank 4. The bag of balls, which can be positioned on the grid 45 or between the grids 45 and 55, comprises micro-balls provided, on their surface, with a determined quantity of volatile agent. The reservoir 4, according to an illustrative example comprises three cavities 42, 43 44, and can therefore receive three bags containing microbeads impregnated with a determined amount of volatile agent. According to a first option, the volatile agents may be different in order to allow the user free to choose the volatile agent that he prefers to broadcast in the passenger compartment of the motor vehicle. A second possibility is to impose a single volatile agent in a first bag, the other bag or bags that can constitute a stock of said single volatile agent and thus avoid a shortage in case of exhaustion of the single volatile agent of the first bag. In a particular example, the tank 4 comprises one or more cavities 46, 47 not provided with diffusion elements. Cavities 46, 47 are used to circulate the flow of air when the user does not wish to release volatile agent within the passenger compartment. Thanks to the actuator 7, 17, 27, the openings 31, 51 of the selection means 3, 5 are positioned to allow the use of the device for diffusing at least one volatile agent 1, 11, 21, 31 according to the wishes of the user. If the cavities 42, 43, 44 are provided with a different volatile agent, the user can choose the type of volatile agent that he wishes to diffuse inside the passenger compartment of his vehicle. If the user does not wish to diffuse volatile agent inside the cabin of his vehicle, the openings 31, 51 of the selection means 3, 5 are then aligned with the cavity or cavities 47 without agent. volatile. The cavities 42, 43, 44, 46, 47 each form an air flow channel to allow the circulation of the air flow generated by the fan. When using the device for diffusing at least one volatile agent 1, 11, 21, 31, the selection means 3, 5 are respectively positioned near the lower and upper surface of the reservoir 4, that is, above and below the tank 4 and this, to ensure that said selection means 3, 5 hermetically seal the various cavities 42, 43, 44. Thus, the cavities which are not not used for the diffusion of a volatile agent are optimally sealed in order to avoid the evaporation of the other volatile agents stored in the other cavities 42, 43, 44 and the diffusion of these other fragrances in the passenger compartment of the motor vehicle . Thus, when the volatile agent selected by the user corresponds, for example, to the volatile agent stored in the cavity 42, the selection means 3, 5 are adapted to close the other cavities 43, 44, 46, 47 and leave the cavity 42 open. Similarly, when the user does not wish to diffuse volatile agent within the cabin of the motor vehicle, the selection means 3, 5 are adapted to close the cavity or cavities 42, 43, 44 provided with a volatile agent to leave the cavity or cavities 46, 47 not provided with a volatile agent not closed. This feature has a real advantage. Indeed, on the one hand, the mixture of volatile agents, during the diffusion of a volatile agent, is avoided and, on the other hand, the diffusion of a volatile agent inside the passenger compartment of the motor vehicle when the user does not wish any volatile agent diffusion, is prevented.
    [0016] According to a particular embodiment, the position of the openings 31, 51 of the selection means 3, 5 can be defined and used in combination with the air flow generated by the fan 2 in order to determine a precise quantity of volatile agent to broadcast inside the passenger compartment of the motor vehicle.
    [0017] The selection means 3, 5 and their respective openings 31, 51 may be positioned so as to allow the flow of air to circulate inside a cavity, for example the cavity 43. The openings 31, 51 are then positioned so as to completely open the lower and upper ends of said cavity 43, and the fan 2 can be used to generate a greater or lesser flow, thus generating a more or less significant scattering of volatile agent stored in the cavity 43, to inside the passenger compartment of the motor vehicle. Alternatively, with a constant air flow generated using the fan 2, the cavity 43 may be more or less closed, thereby generating a greater or lesser flow of air flowing through said cavity 43. diffused volatile agent is therefore greater when the cavity 43 is fully open. It should be noted that the combination resulting from the partial opening of a cavity 42, 43, 44 and an air flow generated by the fan 2 makes it possible to determine the amount of volatile agent diffused inside the the passenger compartment of a motor vehicle. The device for diffusing at least one volatile agent 1, 11, 21, 31 is connected to control means (not shown) notably comprising an electronic circuit making it possible to manage the speed of the fan 2 as well as the drive of the actuator 7, 17, 27 to define the exact position of the selection means 3, 5 when using the device for diffusing at least one volatile agent 1, 11, 21, 31. According to one embodiment, the device 1, 11, 21, 31 comprises a detection device for detecting the position of the selection means 3, 5.
    [0018] It is possible to define cycles of use of the device for broadcasting at least one volatile agent 1, 11, 21, 31 during which a volatile agent diffusion period can alternate with a period of no diffusion of volatile agent over a fixed period. For example, the user can decide on a broadcast cycle providing a broadcast period of 10 seconds per minute for 10 minutes. Such a determined cycle can be used to obtain a progressive diffusion of volatile agent and thus allow a period of prolonged use of the beads impregnated with a volatile agent.
    [0019] Alternatively, the start of the operation of the diffusion device of at least one volatile agent 1, 11, 21, 31 may be related to actions of the user of a motor vehicle. Indeed, for example, when the user starts the vehicle, a first volatile agent diffusion cycle can be engaged. The volatile agent broadcast or shutdown operation may be related to other actions such as, for example, operating the window regulator, turning on the radio, etc. According to one embodiment, the housing of the device is formed of half-housings connected by means of at least one fixing clip.
    [0020] The diffusion device 1, 11, 21, 31 according to the invention may be adapted to be permanently connected to the power supply system of the motor vehicle in which the broadcasting device is to be used.
    [0021] Alternatively, the diffusion device 1, 11, 21, 31 may be provided with an electrical connector to be removably connected to the power supply system of the motor vehicle, by means of an electrical device disposed within said motor vehicle, such as a cigarette lighter.
    [0022] Alternatively, the diffusion device 1, 11, 21, 31 can be electrically powered by means of an independent power supply device.
