    DESCRIPTION
    Evaporation element of volatile substances
    The present invention relates to an element of evaporation of volatile substances, which can be used as an air freshener or as an insecticide.
    Background of the invention
    There are some very simple porous elements on the market that consist of a cylindrical rod made mainly of paper wrapped and impregnated with volatile substances. An example of this type of products is described in WO2006 / 02395.
    These very simple products are designed to be placed on a stand or hung and to release volatile substances in static conditions.
    The use of this type of evaporation elements of volatile substances of wrapped and impregnated paper presents several drawbacks.
    On the one hand, the way in which this paper is wrapped makes the level of compaction higher in the center than in the perimeter, which reduces the ability of the center to behave as a deposit of volatile substances.
    On the other hand, its surface cannot be mechanically altered to increase the evaporation surface, since a cut in the outer paper layer would cause the entire envelope to break.
    There is also the alternative of using wooden rods, but generally this type of material has a high porosity to contain volatile substances, but they are mechanically weak, or they have a high level of density when they have poor absorption capacity but good mechanical resistance. .
    Description of the invention
    With the evaporation element of volatile substances of the invention, the aforementioned drawbacks are resolved, presenting other advantages that will be described in

    The evaporation element of volatile substances according to the present invention comprises a rod impregnated with volatile substances, and is characterized in that said rod is made of sintered wood.
    Advantageously, the porosity of said rod varies between its core and its surface, preferably, the porosity of said rod is smaller in its surface than in its core, for example, 10% less, 30% less or 50% less in its surface than in its core.
    According to a preferred embodiment, the length of the rod is at least seven times greater than the width of the rod, and the rod is substantially cylindrical.
    Advantageously, the core extends up to 50% of the width of the rod, or up to 70% of the width of the rod, or up to 90% of the width of the rod.
    In addition, the rod may comprise at least one groove that extends along it, said groove having at least one groove having a helical shape.
    Preferably, the depth of said at least one groove is between 50% and 10% of the width of the rod.
    The evaporation element of volatile substances according to the present invention allows to obtain several advantages, such as:
    - The capacity of the core of the evaporation element to behave as a deposit of volatile substances is increased;
    - Allows mechanically alter its surface to increase the evaporation surface, for example by making one or more grooves;
    - It allows the evaporation element to be sufficiently porous to adequately fulfill its evaporation function and, in addition, mechanically it is sufficiently resistant.

    Brief description of the drawings
    To better understand how much has been exposed, some drawings are combined in which, schematically and only by way of non-limiting example, a practical case of realization is represented.
    Figure 1 is a perspective view of an evaporation element of volatile substances according to the present invention, indicating the core in dashed lines;
    Figures 2 and 3 are perspective views of two embodiments of the evaporation element of volatile substances according to the present invention, including slots; Y
    Figures 4 and 5 are perspective views of two possible uses of the evaporation element of volatile substances in accordance with the present invention.
    Description of a preferred embodiment
    The evaporation element of volatile substances of the present invention comprises a rod, preferably cylindrical, indicated in general by reference numeral 1. This rod 1 is made of sintered wood impregnated with volatile substances, that is, from particle agglomeration joined by a sintering procedure.
    The sintering process consists in passing an aqueous base paste with wood pulp and binders in a matrix and then drying the rod 1 to remove the water.
    The sintering process allows to obtain a high level of compaction of the particles on the outside of the rod 1, which will cause the formation of a surface 2 with a low porosity and a core 3 with a high porosity.
    The resulting rod 1 has a surface configuration 2 and core 3, where the surface 2 has a lower porosity than that of the core 3. Of course, it should be understood that reference is made to the average porosity, since the porosity varies along of the width or radius of the rod 1.

    The central core 3 with a high porosity provides the rod 1 with a high absorption capacity of the volatile substances, while the surface 2 controls the release of the volatile substances, as well as their mechanical resistance.
    Depending on the design and application, the distribution between surface 2 and nucleus 3 can be established in different relationships.
    Preferably, the width or radius of the core 3 is 70% of the width or radius of the rod 1. Alternatively, a value between 50% and 90% could be used.
    To increase the evaporation surface, the external diameter of the rod 1 can be machined to form one or more grooves 4, for example, a helical groove, as seen in Figure 2 and a plurality of transverse grooves, as seen in Figure 3
    Preferably, the depth of this groove 4 should be sufficient to allow in the area of the rod 1 referred to as surface 2, that is, a depth comprised between 50% and 10% of the width of the rod 1.
    As can be seen in Figures 4 and 5, the volatile substance evaporation element according to the present invention can be used alone or with other elements in a support 5.
    The rod 1 can be hung, for example using a chain that passes directly through a possible hole made in the upper part of the rod, or fixed in a cover fixed at one end of the rod 1.
    The rod 1 can also be fixed to a support 6 that can be attached to the ventilation grill of a vehicle.
    Although reference has been made to a specific embodiment of the invention, it is evident to one skilled in the art that the described volatile evaporation element is susceptible of numerous variations and modifications, and that all the mentioned details can be substituted. by others technically equivalent, without departing from the scope of protection defined by the appended claims.
