[0034] FIG. 1 shows a schematic representation of the bag sectioned along a vertical plane, wherein the different elements that are part of it and how they relate to each other are illustrated.

DETAILED DESCRIPTION

[0036] In view of the figures, a preferred embodiment of the invention proposed is described below.

[0037] FIG. 1 shows the desiccant bag for electronic devices of the invention comprising: [0038] A first outer bag (1) which is made of plastic material which can be hermetically sealed, for example, with a double seal (2). [0039] A second bag (3), housed inside the first bag (1), and made of porous material, leaving a gap between the first bag and the second porous bag, with an absorbent material or drying product (13) being housed in said gap. Both bags, the first (1) and the second bag (3) have a number of partitions, not shown, with the function of separating the products arranged between them, with the aim of forming a uniform layer over the entire surface. [0040] A third bag (4) housed inside the second bag (3), impregnated with an oxygen scavenger material (nitrogen pellets) making it a super-adsorbent material. It is inside this third bag (4), which is porous, where the electronic device (5) to recover and/or protect is housed.

[0041] The first two bags are crossed by a transverse pipe (6), which crosses the interior space defined by both bags, having an inlet (7) and an outlet (8); said pipe has in its interior a connection (14) into which the pipe penetrates from the inlet and emerges towards the outlet (8), and a bypass (9) which, starting from the connection (14) penetrates inside the third bag (4), wherein the electronic device (5) is housed.

[0042] The transverse pipe (6) housed at the ends inside the connection (14) comprises check valves (11) and (12), so that by passing a fluid, preferably air through the inlet (7) towards the outlet (8), in its path it produces a vacuum or a depression inside the third bag (4) causing all the air contained inside to go out, producing contact of the porous wall of this third bag with the electronic device, thus ensuring that the terminal is cleaned and that all residues come out through that hole and that thanks to the heat effect generated and the vacuum produced, it is possible to recover the electronic device which came into contact with a liquid.

[0043] Thanks to the presence of check valves (11) and (12) in the connection (14) a liquid, for example water can be used as depression-producing fluid in the bypass (9).

[0044] In the space between the outer bag and the inner bag, an absorbent or drying material is arranged, preferably polymers which can absorb and retain extremely large amounts of a liquid relative to their own mass, hence they are known as super absorbent polymers.

[0045] Both bags, the first outer bag (1) and the second bag (2) have on their facing sides with a series of partitions that allow uniform distribution of the absorbent and drying product across the entire surface. Furthermore, in the area of the space between both bags, there is an air extraction valve (10).

[0046] As also noted above, the drying bag serves as means for preventing disablement of an electronic device in case of direct contact with moisture. In this case, the inner bag can be removed depending on the size of the object introduced or otherwise a centering element (17) is introduced into the third bag (4), as shown in FIG. 3, in which the electronic device to protect is housed so that the walls of this third bag do not come into contact with the electronic device, and in addition the outlet (8) is covered with a plug or stopper (15), a gas is introduced through the inlet (7) which for example may come from a bottle (16), which can be fixed in the inlet (7) by screwing.

[0047] Said bottle (16) contains a composition of a combination of Co2, n-hexane, isopropyl alcohol and acetone bonded to a fluoropolymer. Thanks to this gas mixed with the powder introduced into the bag, a protective film with hydrophobic properties designed to waterproof the surface and prevent the action of water is formed inside the device.

[0048] Thanks to this gas mixed with powder introduced into the bag, i.e., the drying or adsorbent material (superabsorbent polymers) is formed inside the device a protective film with hydrophobic properties designed to waterproof the surface and prevent the action of water is formed inside the device.

[0049] In some devices, the bypass (9) is inserted through a hole in the device to be protected to ensure the entry of the gasified product, but this is not too important as the product is based on a nanoscale size structure that maintains a microscopic film of air from the nanostructure of super hydrophobic powder on surfaces where the product is sprayed, producing a change in the solid-water basic interface preventing the liquid from interacting with the surface.

[0050] Once the preventive treatment has been performed it is important to avoid in the next 48 hours an accident or getting the treated object wet.

[0051] Also, it is very important to thoroughly clean the object before being treated and if possible remove the battery and any accessories or data card or Sim card in the case of a phone.

[0052] This operation should be done for both treatments, i.e., treatment as a desiccant and as prevention.

[0053] Having sufficiently described the nature of the present invention, as well as how to implement it, it should be noted that, within its essence, it may be implemented in other embodiments that differ in detail from that indicated by way of example, and which are also acquire the protection, provided that its fundamental principle is not altered, changed or modified.
