Definitions
- porous media previously impregnated with the product to be diffused, said porous media possibly being, for example, cellulose supports or pieces of pottery which are not completely varnished.
- the object of the present invention is in particular to improve the methods and devices for manufacturing and diffusing volatile substances such as perfumes.
- the ideal would indeed be to ensure that the perfume diffuser allows to evaporate throughout its lifetime a constant flow of perfume whose relative proportions in its various constituents would be equal to those desired by the perfumer.
- the odor is indeed characterized by the concentrations in the air of the various bodies constituting the perfume. For a given mixture of constituents, there is an ideal composition of these concentrations in the air. A good evaporator must therefore be capable of continuously supplying the ideal composition to the air.
- the aim sought would be that the initial proportions of the product to be evaporated in its different constituents are identical to this ideal composition in the air.

- said elementary components are preferably impregnated in permeable substances constituted by ribbons wound in spirals, the turns of which are spaced and arranged so that the gas flows passing through the containers pass between these turns.
- FIG. 1 illustrates, in a schematic sectional view, the operating principle of a plurality of containers in which are placed porous elements impregnated with a single chemically pure component, these containers being provided with a device for adjusting the air flow through them, said setting being adjustable or not according to the needs of the user.
- This device is particularly well suited to the production of perfumes.
- FIG. 2a shows a schematic horizontal section Iia-IIa and Figure 2b shows a vertical section along llb-IIb, of another embodiment of the invention in which are implemented containers in limited number whose elements porous are saturated by a mixture of elementary bodies of similar volatility, the passage of air in each of these containers at a regulated flow rate making it possible to evaporate a quantity of perfume defined according to pre-established criteria.

- FIG. 7 shows a horizontal section of a container of the evaporator of Figure 5.
- FIG. 8 represents a vertical section of the container of FIG. 7.
- FIG. 9 shows a section corresponding to that of FIG. 6 of an alternative embodiment of the evaporator of FIGS. 5 to 8.
- FIG 1 there is shown a set of n containers 101 in each of which is placed a cellulose wadding 102 impregnated with a pure body constituting a perfume.
- These containers are provided with two pipes 103 and 104 situated at their opposite ends.
- the first of these pipes 103 is connected to a second air distributor 105, itself connected to a first air distributor 115 supplied by a common fan 106 to all distributors 105 and containers. It is provided with a stop valve 107 which is either open or closed.
- the second piping 104 is provided with a valve 108 for adjusting the air flow rate which passes through the container. We know how to adjust this valve as a function of the pressures prevailing on either side of the container to impose a flow rate or, conversely, knowing the adjustment and the pressures to deduce the flow rate therefrom.
- the device is equipped with pressure measurements which are not shown and which are part of the known art which make it possible to achieve these conditions. This circuit is called first circuit in what follows.
- the containers have been distributed into four categories according to the vapor pressure of the bodies to be diffused. All the containers of a category are connected to one of the distributors 105. An air flow control valve 109 is placed between the fan and each of these assemblies which allows a higher flow to be passed over the containers containing the least volatile products and on the contrary a relatively less important flow as the volatility of the bodies increases.
- the air flows leaving the containers then pass through collectors 128, then through a mixer 129 common to all of the containers.
- a common adjustment valve 110 is placed at the outlet of all of the containers, which makes it possible to adjust the total air flow passing through all of the containers. By opening the valve 110 more or less, the overall air flow rate passing through the containers is modified while keeping the proportion of the flow rate to the total flow rate passing through one or other of the containers.
- each container can be heated by means of electrical resistors 11 1.
- electrical resistors 11 1 In practice, only low volatility products will require such heating, which explains why only one resistance has been shown in FIG. 1.
- the entire flow of air passing through the containers is purified by means of activated carbon cartridges 112 located on the flow common to all of the containers upstream thereof, at the outlet of the fan.
- This device can be supplemented by a cartridge 113 intended to lower the vapor content of the water in the air passing through the device, as well as by an air conditioner 114 making it possible to impose its temperature.
- One of the containers used 119 contains water, which is a particular component of a fragrant mixture. It controls the humidity of the air exiting the device.
- this particular container which is crossed by an air flow much greater than that of the other containers is supplied by a specific fan 120 whose flow rate is much greater than that of the fan which creates the air flow passing through the containers.
- two parallel circuits 127 and 132 are implemented provided with flow adjustment valves 124, 125 and 126. This circuit is called the second circuit.
- the moist air leaving this second circuit is then mixed with the air having passed through the first circuit and which is charged with perfumes, this mixture being carried out in the mixer or chamber 30. After mixing, the flow of perfumed air s' extracted from the device through orifice 13 1.
- each container 101 The air flow rate passing through each container 101 is sufficiently low for it to saturate with vapor from the component of the container, that is to say that the partial vapor pressure of said component in the air is almost equal to what it would be after a very long time in a stagnant air.
- This partial pressure is called the vapor pressure at temperature considered.
- the ratio between this partial pressure of the pure component in the air and its vapor pressure will be at least equal to 0.8.
- Such a condition is obtained according to the invention by using porous bodies whose exchange surface is sufficiently large, which are cellulose wadding in our example, these methods being known from the prior art.
- the air flows thus leaving the containers and containing known quantities of perfumes are then mixed together in a first mixer 129, then with the air flow from the secondary circuit in a second mixer 130.
- the arrangement of the general adjustment valve 11 0 located between the first mixer and the second mixer makes it possible to maintain the relative proportions of perfume while modifying the total air flow rate of the first circuit, saturated with perfume, leaving all of the containers. It is thus possible to adjust the power of the perfume in the outlet air flow by acting on the opening of the valve 110.
- the assembly thus constituted therefore makes it possible to produce a metering and mixing system of pure bodies constituting a perfume, this mixture, the proportions and total flow of which are continuously adjustable, being itself mixed with an air flow variable. It therefore creates an atmosphere containing a perfume whose components are controlled in proportions and quantity. In principle, as long as the number of basic bodies is sufficient, any odor can be created at will, the odor being the result, pleasant or not, of a mixture of such elementary bodies. This system is particularly well suited to creation in perfumery.
- the device will be controlled by an automaton making it possible to carry out the dosing and mixing operations as well as the measures necessary for their control.
- This automaton will be provided with means for memorizing compositions as well as automatic modes making it possible to create particular mixtures. In general, it is a matter of creating in the air a homogeneous mixture of elementary bodies in proportions defined.
- This automaton which is part of the known art, is not shown in FIG. 1.
- FIGS 2a and 2b give another embodiment of the invention in which a limited number of containers 201 (201 a to 201 h) is used, for example eight containers. Each of these containers is filled with a porous body 202 soaked in a mixture of several elementary bodies of neighboring volatilities. In this example, this porous body 202 is a cellulose wadding. In what follows, “volatility of a pure body” is called the product of the vapor pressure of said body by its molar mass.
- the first container 20 1 a is filled with the most volatile elementary bodies, characterized by a maximum ratio of their volatilities equal to 2.
- the second container 201_b is filled with bodies a little less volatile also in a maximum ratio of volatilities equal to 2. Successive containers are filled according to this same principle with bodies of decreasing volatilities.
- the range of volatilities covered is at least equal to 2 S (two to the power 8), or 256. This means that the ratio of the volatility of the most volatile body contained in the first container the volatility of the least volatile body contained in an eighth container is at least 256. In general, the range covered will be slightly greater than 256 since the volatilities of the constituent bodies of a substance are discrete values and the passage of one container to another is never done continuously.
- the relative quantity of each constituent in the set of containers is generally equal to the proportions of said bodies which it is desired to obtain in the air.
- the containers are provided with an inlet orifice 203 communicating with an inlet chamber 203 a and an outlet orifice 204 communicating with a mixing chamber 208, the surface of the inlet orifice 203 being much greater than that of the outlet orifice 204.
- a fan 205 driven by a motor 206 makes it possible to introduce air into the inlet chamber 203 a.
- An air flow is imposed in each of the containers by means of the fan 205 by imposing or calibrating for each of them the surface of the outlet port 204 so that the desired flow rate is obtained. This type of adjustment is done by applying the laws of fluid mechanics which are part of the known art.
- These individual air flows passing through the containers then pass into a mixing chamber 208 which makes it possible to obtain a homogeneous mixture of air and of the various scented components, these scented compounds being in the proportions finally desired in the air.
- these individual flows are mixed with an unscented air flow passing around the containers and in particular in the orifices 209 and 207 in order to avoid deposits by condensation.
- an adjustable outlet orifice 210 acting as a valve intended to regulate the total flow passing through the device, this outlet orifice 21 0 being adjustable by rotation of two discs 21 0a and 21 0b having corresponding through holes brought more or less in coincidence.
- the dimensions of the device are as follows.
- Each container is provided with hydrophilic wadding impregnated with the components of the perfume to be evaporated. They all have a diameter of 25 mm and a height of 40 mm.
- the cross-section of the container inlet is 0.75 cm 2 .
- the vapor pressure of the most volatile body placed in the container 20 1 a is 10 Pa and its molar mass is 150 g. The volatility of this body is therefore equal to 1.5 Pa.kg.
- the vapor pressure of the least volatile body placed in the last container 20 1 h is 0.02 Pa and its molar mass of 200 g. Its volatility is therefore 0.004 Pa.kg.
- the first container initially contains a total mass of fragrance components of 2 g and the last contains a total mass of 0.5 g.
- the air flow rates implemented are 1.5 ml / s for the first container and 90 ml / s for the last container, respectively. For the other containers, they depend on the exact composition of the mixtures they contain.
- the device makes it possible to diffuse a perfume in a room of approximately 25 m 3 .
- the total mass of perfume after filling the device is 10g, which corresponds to an operating time of one month.
- the total flow rate of the fan is 500 ml / s, of which only 200 ml / s pass through the container.
- the residual air flow of 300 ml / s passes through the specific conduits located between the containers before being mixed with the air flows almost saturated with vapor leaving each of said containers.
- the theoretical (aerodynamic) power of the fan is -5 mW, which, taking into account the yields, leads to an actual power of 20 mW.
- the fan is connected to the electrical network, which makes it possible to heat the air entering the last container 201 h by means of the electrical resistance not shown.
- the engine can be powered by electric accumulators 21 1 or by cigarette lighter sockets of private cars.
- the device is used to scent a large space, such as a public transport station.
- the volume of this station is for example fifteen thousand cubic meters.
- this flow rate was ten grams per month for twenty five cubic meters. It therefore becomes equal to six thousand grams / month, or six kg / month for a public transport station.
- ten apparatuses of this type are used, the total initial charge of perfume being six hundred grams, therefore sixty times greater than the previous one.
- the containers 301 are arranged one above the other in a cylindrical column 306.
- the air which enters the column through the lower inlet orifices 310 via an inlet chamber 302a, is driven by a lower fan 305. It then passes through containers 301 which are provided with internal lateral inlet ports 302 and external lateral outlet ports 303. On passing through the containers 30 1, the air . takes care of the perfumed mixtures which permeate the wadding 304 contained in the containers. he then passes into the annular space 307 surrounding the containers 30 1 and into an upper mixer or upper mixing chamber 308.
- FIG. 4 shows a perfume display 409 equipped with several sets of containers 403, each of said sets of containers containing a specific perfume.
- Each set of containers is connected to a fan 401 common to the display unit supplied with pure air through orifices 409.
- Each set of containers is moreover provided with a valve 404 allowing the air coming from the fan to pass through it or not according to whether it is open or closed.
- the open valve is denoted 405.
- This air charged with perfume is then introduced into the tube 406, then into the mixer or chamber 407.
- a main flow of air from the fan passes directly to the mixer through duct 410, which makes it possible to produce an intimate mixture of the main air flow and the perfumed air flow having passed through at least one set of containers.
- the consumer will thus be able to choose a perfume corresponding to his tastes.
- the opening of the valves can of course be automated and it is possible to test a mixture of several perfumes, or essences such as for example those used in aromatherapy. To do this, it is sufficient to simultaneously open several valves 404.
- the evaporator 500 shown in FIGS. 5 to 8 comprises a box 50 1 which comprises a vertical cylindrical wall 502 and, at low distance from its lower end, a horizontal radial wall 503.
- This radial wall has a central passage 504 and passages or orifices 505 distributed around its periphery.
- the radial wall 503 carries a motor 506 from above, the axis 507 of which passes through the passage 504 and. is provided, below this radial wall i, with a fan blade wheel 508.
- An attached radial wall 509 is fixed to the container 50 1 and extends just below the blades 508, this attached wall having a passage input 509a. Below this added plate 509, the peripheral wall 502 of the container 50 1 has inlet orifices 502a. Between the radial wall 503 and the added radial wall 509 is provided a rectifier blade 51 0 carried by the added plate 509 and surrounding the blades 508.
- the evaporator 500 further comprises a cartridge 51 1 whose general shape is cylindrical and which delimits 8 vertical containers 512 distributed around a central passage 513 in which the motor 506 is engaged.
- This removable cartridge is engaged from above in the box 501, its lower radial wall 514 being kept at a distance from the radial wall 503 by virtue of a projecting support 51 5 provided on this radial wall around the motor 506, so that an inlet chamber 505 a is provided below the removable cartridge 51 1.
- the peripheral part of the cartridge 51 1. has vertical grooves 51 6 formed between each container 512 and in the lower radial wall 514.
- Each container 512 has at least one lateral inlet through hole 51 7 connected to an adjacent groove 516. This lateral through hole 516 is placed approximately halfway up each box.
- the upper radial wall 518 of the cartridge 51 1, the periphery of which is adjusted in the box 50 1 has calibrated through passages or orifices of outlet 51 9 which are placed in the center of the containers 5 12.
- the upper wall 518 also has 520 calibrated through passages or orifices located respectively above the grooves.
- the evaporator 500 further comprises a removable intermediate cover 521 placed above the removable cartridge 51 1.
- This intermediate cover 52 1 comprises a radial disc 522 whose periphery is supported on an inner shoulder of the upper edge of the peripheral wall 502 of the container 501 and which extends above and at a distance from the cartridge 5 1 1.
- the intermediate cover 52 1 further comprises a cylindrical skirt 523 projecting downward from the disc 522 and which engages slightly in the central passage 513 of the removable cartridge, this skirt having passages 524 opening above the cartridges.
- the removable intermediate cover 521 thus delimits a mixing chamber 52 1 a above the cartridge 51 1, including the central passage 513 obstructed at its lower parity by the radial wall 503 and the motor 506.
- the disc 522 also has, for example, two through holes 525 off-center opening into the interior of the skirt ' 523.
- the evaporator 500 also comprises a removable upper cover 526 which envelops the upper part of the box 501 and which has two orifices 527 capable of being brought into coincidence with the orifices 525 of the intermediate cover 521.
- permeable materials constituted by ribbons 528 wound in a spiral are placed in the containers 512.
- the turns of the ribbons 528 are kept apart, for example by wound wires 529.
- the ribbons extend over the entire height of the containers 512 and are impregnated with volatile substances.
- the evaporator 500 is intended in particular to reconstitute a perfume from the evaporation of its elementary components.
- the ribbons 528 contained in each of the containers 512 are impregnated with elementary components of the perfume whose molecular weight products by their vapor pressure, which represent the volatility, are fairly close.
- Each of the containers therefore contains mixtures of increasingly volatile components. For example, if we consider that the maximum difference between the volatilities of the species contained in a box is 2, we see that by implementing 8 containers, we cover at least a range of volatilities equal to
- each box being themselves proportional to the surface of the corresponding calibrated orifice 519 and to the square root of the pressure difference prevailing between the interior of the groove 516 and of the mixing chamber 521 a, the relative flows of each of the components are independent of the total air flow.
- the components contained in the boxes are those of a perfume, it can be seen that the quality of the latter, its odor, is constant as a function of time since this depends only on the relative quantities of the elementary components of the perfume.
- the evaporator 500 operates in the following manner.
- the air entering from the lower part of the container 50 1 through the lateral passages 502a is directed between the radial walls 503 and 509 to pass via the passages 505 into the chamber d entry 505 a.
- the air then engages in the vertical channels 530 formed by the vertical grooves 5 1 6 of the cartridge 51 1 and the cylindrical wall 502 of the container 501.
- Part of the air enters the containers 512 through the lateral orifices 51 7 while the other part passes through calibrated through orifices 519.
- the part of the air entering the containers 512 is forced to pass between the turns of the ribbon 528 of permeable substance and emerges from the containers through the calibrated upper ports 51 9 while being charged with the vapors of the components with which the ribbons 526 are impregnated. orifices 519 mix during their passage in the upper chamber 521 a and the mixture is discharged to the outside through orifices 525 of the intermediate cover and 527 of the upper cover.
- the upper calibrated orifices of the cartridge 51 1 are respectively adjusted to the vo latile substances contained in each and the direct air circulation orifices are calibrated as a function of the orifices 5 1 1 and of the desired maximum volatile matter flow rate.
- the upper cover 526 By rotating the upper cover 526, it is possible to adjust the outlet section of the evaporator by making the openings 525 of the intermediate cover 52 1 coincide more or less with the openings 527 of this upper cover 526.
- the components to be evaporated contained in the removable cartridge 51 1 are exhausted, it suffices to remove the upper cover 526 then the intermediate cover 521, to extract the cartridge 51 1, to install a new cartridge 51 1 with impregnated ribbons 528 and of . replace the upper cover 526 then the intermediate cover 521.
- FIG. 9 we see that there is shown an alternative embodiment of the evaporator 500 described with reference to Figures 5 to 8, wherein this evaporator is provided with an annular disc 550 which is placed flat on the upper face of the wall 51 8 of the cartridge 51 1.
- This disc 550 has a central passage engaged with little play around the skirt 523 of the intermediate cover 52 1 and has an outside diameter located at a distance from the cylindrical wall 502 of the box 501 so that the orifices 520 of the wall 518 of the cartridge 51 1 are not covered.
- the disc 550 has a tongue 55 1 which extends flat from its periphery and which passes through a slot 552 formed in the cylindrical wall 502 of the box 501, so that by acting on the tongue 55 1, it can rotate the disc 550 around the skirt 523 between two extreme positions in which the tongue abuts respectively against the ends of the slot 552.
- the disc 550 has two series 553 and 554 of through passages 555 and 556 arranged so that, when it is placed in one of its extreme positions, the through passages 555 uncover some of the orifices 519 of the cartridge 51 1, and, when it is placed in its other extreme position, the through passages 556 discover the other ports 519 of this cartridge.
- the evaporator 500 is thus adapted to generate two volatile substances.
