DESCRIPTION

Volatile evaporator device

The present invention relates to a volatile element evaporator device that efficiently exploits the calorific value of the radiation.

Background of the invention

10 Volatile evaporator devices are known, comprising a body embedded in a liquid or solid to be evaporated and means of supplying heat to the liquid

or solid to evaporate or sublimate respectively.

In the market there are available heaters consisting of axial resistors, 15 SMD resistors or PTC. These technologies are often used in electric air fresheners,

or in insecticide evaporators mainly by price and operation. In most air fresheners, the heater heats the liquid in a hair wick, increasing the vapor pressure and increasing the rate of evaporation. Said heat transmission is mainly carried out by the conduction and / or convection phenomena.

20 radiation being an insignificant phenomenon.

There are other ways to vaporize liquids in the air, not necessarily by heating, which can be by moving air with a fan, shaking the liquid with ultrasonic, piezoelectric vibrations or with an electromechanical actuator to open-close a

25 aerosol valve

On the other hand, the perfume used in an air freshener is the sum of many chemical components that, when mixed, emit a characteristic and supposedly pleasant smell. Solvents are also used to adjust durations and

30 intensities of perfume or insecticide.

The behavior from the point of view of heat absorption of the perfume (or any substance to evaporate) with respect to light is not optimal for use as a source of heat. It practically does not absorb radiation, which makes it impossible to heat perfume (or

35 any substance to evaporate) to evaporate using light.

To be able to heat, the transmittance must be different from 100%. Ideally to maximize energy, it should be 0.

(1) In the visible range (between 400 and 750 nm) the transmittance is total. It makes no sense to emit light because the perfume is transparent

5 (2) In the infrared band (> 750 nm) there are areas that do absorb radiation. Ideally, the longer the wavelength, the better. There are light emitters at a very high wavelength, above 2000 nm, but they are currently economically unfeasible for high-consumption equipment.

(3) From the economic point of view there are currently only viable LEDs in the visible range 10 and near infrared.

Therefore, with current devices it is not possible to use radiation as an effective alternative to other heating means.

Description of the invention

In order to solve the aforementioned drawback, the present invention proposes an evaporator device for volatile elements, comprising:

-A body embedded in a liquid or solid to evaporate;

-means of heat supply to the liquid or solid to evaporate;

30 characterized in that said means of supplying heat to the liquid or solid to be evaporated consist of one or more radiation emitting elements arranged to radiate at least a part of the body.

35 The said body must be selected to absorb the radiation emitted by the emitters.

In this way, the liquid or solid to be evaporated / sublimed is not directly heated, but the said embedded body is heated. The inventors have been able to verify that in this way a greater homogeneity of temperature of the entire surface of the surface is achieved.

5 wick

In addition, the fact of using radiation allows a safer isolation between the energy source and the material to be heated.

According to a particularly preferred variant of the invention, the device comprises:

-a deposit filled with a liquid to evaporate; -in which said body is at least one capillary wick that has a lower part intended to be submerged in the liquid and an upper part that protrudes outside the

15 deposit; -in which the radiation emitting element (s) are arranged to radiate at least a part of the wick protruding from the tank, so that said part of the wick protruding directly from the tank is heated directly, which in turn heats the liquid contained in said part and the liquid evaporates

20 contained in said part, which causes the liquid contained in the tank to rise from the submerged part towards said protruding part.

Mecha should be understood as the element that carries the liquid, and that a plurality of wicks arranged together also in this sense equals a wick.

According to various other optional features of the invention, taken in isolation or in combination, whenever technically possible:

-the radiation emitting element or elements are LEDs (Light Emiting Diodes), and 30 are preferably LEDs emitting in the infrared.

-the body is made of polyamide and polyethylene terephthalate, and more preferably it is of the commercial product Filtrona ® BNL 439860.

35 -the device comprises an excitation source of the radiation emitting element (s) that is pulsed or continuous, which also allows automatic control

more versatile dosage.

-the device comprises a housing provided with a plug to an electrical outlet.

5 -the radiation emitting element or elements are integrated in the housing.

-the device comprises removable coupling means from the tank to the housing.

Finally, the coupling means are threaded or pressure.

Brief description of the figures

To better understand how much has been exposed, a drawing is attached in which, schematically and only by way of non-limiting example, a case is represented

15 practical implementation.

Figure 1 is a very schematic drawing showing the main components of the device of the invention.

20 Description of a preferred embodiment

As can be seen in the single figure, the invention relates to a volatile element evaporator device 1, which comprises a body 3 embedded in a liquid or solid L to evaporate and heat supply means 4 to the liquid or solid L to evaporate .

25 Normally, these means consist of a resistor.

Now, according to the present invention, the means of supplying heat to the liquid to be evaporated or solid L to sublimate consist of one or more radiation emitting elements 4 arranged to radiate at least a part of the body 3.

According to an especially preferred embodiment, which is illustrated in Figure 1, the device comprises:

-a deposit 2 filled with a liquid L to evaporate;

35 -in which said body 3 is a capillary wick 3 having a lower part 3a intended to be submerged in the liquid L and an upper part 3b protruding outside the

P201330408

03-21-2013

deposit 2; -in which the radiation emitting element (s) 4 are arranged to radiate at least a part 3b of the wick 3 that protrudes from the tank 2, so that said part 3b of the wick 3 protruding directly from the

5 tank 2, which in turn heats the liquid contained in said part and the liquid contained in said part 3b evaporates, which causes the liquid L contained in the tank 2 to rise from the submerged part 3a towards said part which excels 3b.

These radiation emitting elements 5 are LEDs that emit in the infrared. In combination with these LEDs, the inventors have been able to verify that a body 3 of polyamide and polyethylene terephthalate is especially efficient.

As an example of a body containing these components, the commercial product Filtrona ® BNL 439860 can be cited.

15 It is also provided that the device comprises an excitation source of the radiation emitting element (s) 4 which is pulsed or continuous, a housing 5 provided with a plug 6 to an electrical outlet. The radiation emitting elements 4 will preferably be integrated in the housing 5, in which the

20 tank 2, for example by threading or pressure.

Although reference has been made to a specific embodiment of the invention, it is apparent to one skilled in the art that the described device is susceptible to numerous variations and modifications, and that all the mentioned details may be

25 substituted by other technically equivalent ones, without departing from the scope of protection defined by the appended claims.

For example, it can be conceived to combine the radiation source with other energy sources currently used, such as a resistor, or the heat emitted directly by the 30 radiation sources.
