    Device for diffusion of volatile substances
    The present invention relates to a device for diffusion of volatile substances, in particular to a device in which one or more volatile substances are diffused by an air flow of non-cylindrical geometry. Background of the invention
    10 Electrical devices are known, which are powered by batteries, batteries or the mains, which diffuse volatile substances by generating an air current through a blade fan.
    15 This type of device is normally designed to increase efficiency and achieve optimal control by the user of the level of dispensing or evaporation.
    This type of device is designed to improve evaporation and / or diffusion of volatile substances with the help of an additional air flow, even without temperature conditions.
    These devices, however, have a number of drawbacks, which are indicated below.
    25 On the one hand, most of the above solutions have a high or very high energy consumption, which sometimes can hardly work with batteries, and if it does, the duration of these batteries is very limited.
    On the other hand, with the known fan devices, the generated air flow has a cylindrical geometry, which does not coincide with the majority of the volatile substance diffusion elements, which are usually rectangular in projection.
    In addition, within this cylindrical geometry, the highest air velocity is in the most perimeter zone, which usually does not coincide with the diffusion element of volatile substance 35. This implies that a large part of the air flow is wasted, which implies, again, a loss of energy efficiency.
    P201331931
    12-30-2013
    On the other hand, the noise of the previous solutions may not be negligible, and may even increase over time. This may imply inconvenience to the user.
    5 Another important point in some of the above solutions is the size and shape that they adopt, usually of large volume, which requires designing the electric diffuser with a considerable size.
    Therefore, the need for a device for the diffusion of volatile substances 10 that solves the aforementioned drawbacks is evident. Description of the invention
    With the device for diffusion of volatile substances of the invention are achieved
    15 to solve the aforementioned problems, presenting other advantages that will be described below.
    The device for diffusion of volatile substances according to the present invention comprises means for generating an air current, and is characterized in that
    20 said means for the generation of an air stream comprise a flexible sheet and at least one piezoelectric element, so that said piezoelectric element undergoing expansion and contraction causes the oscillation of said flexible sheet to generate the air stream.
    According to an alternative embodiment, said means for generating an air current comprise two piezoelectric elements, said piezoelectric elements being placed on opposite faces of said flexible sheet.
    Advantageously, the device for diffusion of volatile substances in accordance with the
    The present invention also comprises a container of volatile substances that defines an evaporation surface, and in which the end of said flexible sheet that generates the air flow is oriented towards said evaporation surface.
    Preferably, the width of said end of said flexible sheet that generates the
    The air flow coincides with the width of said evaporation surface. In case the evaporation surface is a wick, said width of the flexible sheet can
    P201331931
    12-30-2013
    match the wick diameter.
    In addition, said flexible sheet may preferably be rectangular or quadrangular.
    5 According to an optional embodiment, said means for generating an air stream are housed in a housing, said housing being provided with air inlet and outlet holes.
    The device for diffusion of volatile substances according to the present invention 10 provides at least the following advantages:
    -It allows to generate an air flow adapted to the geometry of the evaporation surface.
    -The energy consumption is lower than in conventional devices which makes 15 that, in case of using batteries, the duration of these is longer than in conventional devices.
    -The dimensions and operation of the device according to the present invention make it possible to have different air flows (and, therefore, different evaporations) depending on the position in which the flexible sheet is in relation to the substance volatile to evaporate.
    -The noise is virtually negligible throughout the life of the product, since there is no friction or wear on the materials.
    25 -The regulation of the air flow can be generated by modifying the amplitude of the voltage, but also by modifying the frequency of the generated alternating signal.
    -The evaporation control and adjustment can also be done by housings, opening and closing the air inlet and / or outlet depending on the desired air flow.
    -The size of the device according to the present invention is configurable and adjustable according to the application
    35 -Optionally, if the system to be evaporated needs it, several devices could be used together.

    12-30-2013 Brief description of the drawings
    For a better understanding of what has been exposed, some drawings are attached in which, schematically and only by way of non-limiting example, a practical case of embodiment is represented.
    Figure 1 is a schematic elevational view of the device for diffusion of volatile substances according to the present invention, according to a first preferred embodiment;
    Figure 2 is a schematic plan view of the device for diffusion of volatile substances according to the present invention, according to a second preferred embodiment; Y
    Figure 3 is a schematic elevational view of the device for diffusion of volatile substances according to the present invention, according to a third preferred embodiment. 15 Description of a preferred embodiment
    In accordance with the embodiment presented in Figure 1, the device of the present invention comprises air flow generating means, comprising a
    20 flexible sheet 1 and a piezoelectric element 2. Said flexible sheet 1 is preferably rectangular or quadrangular, or could have any suitable shape. For example, it could have some curved part if necessary for some reason.
    Said piezoelectric element 2 is connected to a power supply 8, of
    25 so that when an alternating voltage is applied to said piezoelectric element 2, it expands and contracts.
    This phenomenon causes the sheet 1 to flex and oscillate at the same frequency of the applied voltage. This oscillatory movement causes an air flow that can be used
    30 to help and / or improve evaporation and / or diffusion of volatile organic substances.
    In the event that the power supply 8 is one or more batteries, an additional circuit, not shown, will be necessary to generate and amplify the alternating signal necessary for the operation of the piezoelectric element. In the event that the source of
    35 power supply 8 be the mains, the additional circuit may not be necessary.
    P201331931
    12-30-2013
    This additional circuit is capable of controlling the air flow by modifying the amplitude and / or frequency of the signal generated to feed the piezoelectric element 8, whereby evaporation and / or diffusion of volatile organic substances could be controlled.
    5 Figure 1 also depicts a container 3 that includes, among others, the volatile substance to be diffused, said container defining an evaporation surface 4, which in this case can be a wick. In this case, the width of the flexible sheet may coincide with the diameter of the wick, although it could also be of a different dimension.
    10 As can be seen in the figure, the end of said flexible sheet 1 that generates the air flow is oriented towards said wick.
    In figure 2 a second embodiment is shown, in which the flexible sheet 1
    15 is arranged perpendicularly on a membrane 9. In this case, the air flow is confined in a rectangular geometry parallel to the evaporation surface.
    A third embodiment is shown in Figure 3, in which the flexible sheet 1 and the piezoelectric element 2 are arranged inside a housing 5.
    20 Said housing 5 is provided with an inlet cover 10 with a plurality of inlet holes 6 and an outlet cover 11 with a plurality of outlet ports 7, such that air circulates inside said housing 5 through the action of said flexible sheet 1 when actuated by said piezoelectric element 2, as described
    25 previously.
    In this case, it can be seen in Figure 3 that the width of said end of said flexible sheet 1 that generates the air flow substantially coincides with the width of said evaporation surface 4.
    Although not shown in the figures, it should be noted that the means for generating an air current could comprise more than one piezoelectric element 2, for example two piezoelectric elements, placed on opposite faces of said flexible sheet 1.
    Although reference has been made to a specific embodiment of the invention, it is
    P201331931
    12-30-2013
    It is clear to one skilled in the art that the device for diffusion of volatile substances described is susceptible of numerous variations and modifications, and that all the mentioned details can be replaced by other technically equivalent ones, without departing from the scope of protection defined by the appended claims. .
