Description

[0001] PORTABLE ESSENTIAL OIL DIFFUSION SYSTEM

[0002] The present invention relates to a portable essential oil diffusion system for one user, and more particularly to such a system equipped with a nebulizing device arranged to cooperate with at least one removable and / or rechargeable reservoir comprising an essential oil solution.

[0003] Diffusion methods and, more recently, essential oil diffusers are well known in terms of the state of the art.

[0004] Indeed, historically the diffusion of essential oils was carried out by placing a few drops on a fabric such as a cloth handkerchief or by mixing the essential oils with candle wax to be diffused at a high temperature.

[0005] More recently, given that high-temperature diffusion had certain disadvantages, gentler diffusers have been developed, for example, gentle heat diffusers or ventilation diffusers.

[0006] Unfortunately, although they allow for an improvement over older techniques, the effectiveness of these diffusers remains limited.

[0007] Ultrasonic essential oil diffusers have therefore been developed, in which the essential oil is mixed with water and ultrasonic vibrations transform this mixture into a fine mist. This method is particularly advantageous because it does not heat the essential oil, thus preserving its properties.

[0008] There are also essential oil diffusers using nebulization technology which atomize the essential oil into microparticles using air pressure.

[0009] Finally, such devices can also be connected to a smartphone or an electronic board to be programmable, or to further personalize the broadcast.

[0010] We also know the benefits of diffusing essential oils which can be for well-being and relaxation, for certain therapeutic properties or even for the purification of indoor air.

[0011] Unfortunately, although these essential oil diffusers may have some advantages, they could be improved. Indeed, the diffusers allow diffusion into the surrounding air, and it turns out that this can be undesirable for those nearby, or even disturbing, or harmful and toxic to pets.

[0012] For example, a user who wants to relax while working in their office with a conventional essential oil diffuser will inadvertently release particles into the surrounding rooms, which is undesirable for those nearby and even more so for pets. At best, the user can isolate themselves and close their office door, but in this case, diffusion in a confined and poorly ventilated space can lead to adverse effects or allergic reactions.

[0013] There is therefore a real need to provide an essential oil diffuser that allows users to avoid contaminating their environment, that prevents the generation of undesirable effects or allergic reactions, and that optimizes the necessary consumption of essential oil while maintaining its effectiveness.

[0014] One objective of the present invention is to overcome the challenges and biases of the state of the art.

[0015] In particular, one objective of the present invention is to provide a portable essential oil diffusion system for a user that allows for local and optimized diffusion.

[0016] Furthermore, an objective of the present invention is to provide a portable essential oil diffusion system that limits and optimizes the consumption of essential oil solution and reduces the generation of adverse effects or allergic reactions.

[0017] The present invention aims to overcome the drawbacks of the prior art by providing a portable essential oil diffusion system for a user, equipped with a nebulizing device arranged to cooperate with at least one removable and / or refillable reservoir containing an essential oil solution. The nebulizing device comprises an electronic board connected to at least one power supply and at least one piezoelectric element, which includes a central micro-perforated membrane and a perimeter encapsulated in a circumferential seal fixed within the inner light of a housing. This at least one central micro-perforated membrane comprises a first outer surface arranged to be in contact with the surrounding air, and a second inner surface arranged to be in contact with at least one capillary of a reservoir.said at least one removable and / or refillable reservoir includes a storage space for an essential oil solution being a cavity with at least one opening and at least one capillary comprising a first end arranged to be in contact with said second lower surface of said micro-perforated central membrane and said capillary being in direct contact with the essential oil solution in the storage space of the reservoir through the opening to convey the essential oil solution from the reservoir by capillary action.

[0018] As can be seen, the portable essential oil diffusion system for one user according to the present invention has on the one hand a nebulizing device and on the other hand at least one removable and / or rechargeable reservoir containing an essential oil solution.

[0019] In addition, the nebulization system includes:

[0020] an electronic circuit board connected to at least one power supply and at least one piezoelectric element,

[0021] at least one piezoelectric element comprises a central micro-perforated membrane and a perimeter encapsulated in a circumferential seal fixed in the inner light of a housing, more particularly, at least one central micro-perforated membrane comprises a first outer surface arranged to be in contact with the surrounding air, and a second inner surface arranged to be in contact with at least one capillary of a reservoir.

[0022] This advantageously allows for the provision of a nebulizing device that operates autonomously and is portable for a user to provide local diffusion close to the user's nose.

[0023] Thus, the device according to the invention allows the user to benefit from the advantages of nebulizing essential oils in a localized manner directly near their nose, thereby greatly reducing the necessary dose while maintaining effectiveness, and advantageously without disturbing those around them.

[0024] Furthermore, the use of a piezoelectric element comprising a central micro-perforated membrane allows the diffuser to function and be activated only when the piezoelectric element is excited at its resonant frequency. Thus, the excitation signal to the piezoelectric element from the electronic board is pulsed, giving the user the visual impression of continuous diffusion while limiting the device's energy consumption, the consumption of essential oil solution, and extending the device's lifespan according to the present invention by maintaining stable diffusion over time and across multiple usage cycles.

[0025] Finally, at least one removable and / or refillable reservoir comprising a storage space for an essential oil solution, being a cavity in which the solution is located with at least one opening giving access to the piezoelectric element, and at least one capillary comprising a first end arranged to be in contact with said second lower surface of said central micro-perforated membrane through the opening and a second end in the storage space, the capillary being in direct contact with the essential oil solution in the storage space of the reservoir to convey the essential oil solution from the reservoir by capillary action to the piezoelectric element through the opening, allows the user to interchange the aroma and the essential oil solution from one use to another, while maintaining the sealing of the device according to the invention.

[0026] Indeed, the housing of the nebulizing device according to the present invention includes a light in which the piezoelectric element is fixed, making accessible to the surrounding air only the first outer surface of the central micro-perforated membrane, on the other side of this membrane, at least one capillary of the reservoir is in direct contact with the essential oil solution in the storage space in order to convey the essential oil solution from the reservoir by capillarity, and the reservoir acts as a tight stopper in order to close the housing.

[0027] Preferably, at least one capillary is an absorbent material, for example cotton. Indeed, an absorbent material such as cotton absorbs the essential oil solution present in the storage space and brings it to its first end in contact with the second lower surface of the central micro-perforated membrane, allowing a constant supply of the essential oil solution to at least one piezoelectric element, and therefore sufficient diffusion of essential oil.

[0028] According to one embodiment, the reservoir further comprises a spring located in the cavity, the capillary being made of absorbent material and positioned between the spring and the piezoelectric element, the spring ensuring that the absorbent material remains in contact with the second inner surface of the central micro-perforated membrane.

[0029] Thus, the portable essential oil diffusion system according to the present invention can be activated on demand by the user, providing a direct and targeted diffusion towards the user's nose in order to avoid disturbing those around them, while providing an economical device, whose energy and essential oil consumption is optimized and finally avoiding unwanted drips or leaks.

[0030] According to a particular embodiment, at least one removable and / or refillable reservoir containing an essential oil solution is a removable reservoir.

[0031] According to another particular embodiment, at least one removable and / or refillable reservoir containing an essential oil solution is a refillable reservoir.

[0032] Advantageously, at least one removable and / or refillable reservoir further includes a cover covering at least one capillary and the cavity opening, preferably an aluminum cover.

[0033] Equally advantageously, the nebulizing device includes at least one opening and / or drilling means located at the level of the second lower surface of the central micro-perforated membrane arranged to perform an opening and / or drilling of the lid when at least one reservoir cooperates with the nebulizing device.

[0034] The presence of a seal ensures a leak-proof reservoir, preventing any essential oil from leaking before use. This facilitates storage and transport while preserving the quality of the essential oil solution. Furthermore, the automatic opening and / or piercing of the reservoir seal, when the reservoir is used with the device, eliminates the need for the user to manually open and / or pierce the seal, which could result in product loss, stains, or odor residue on the fingers. This also allows for optimal opening and / or piercing, ensuring the essential oil solution flows correctly to the central micro-perforated membrane.

[0035] More advantageously, the at least one removable and / or rechargeable reservoir further includes a fastening element arranged to secure the at least one reservoir in the inner light of the nebulizing device housing with the at least one capillary of the reservoir in contact with the second inner surface of the central micro-perforated membrane, preferably the fastening element is an annular fastening element surrounding the reservoir.

[0036] Even more advantageously, the securing element includes at least one locking lug, preferably at least two locking lugs, arranged to cooperate with at least one notch, preferably at least two notches, of the internal light of the housing of the nebulizing device.

[0037] This securing element allows the reservoir to be held in the optimal position when used with the nebulizer, thus preventing the user from having to manually hold it during system operation. It also acts as a seal, minimizing the risk of essential oil solution leakage when the reservoir is connected to the device.

[0038] Preferably, the nebulizing device further includes a lid having a closed position and an open position, the lid in the closed position being arranged to cover the first outer surface of the central micro-perforated membrane of the piezoelectric element, and the lid in the open position being arranged to allow the first outer surface to be in contact with the surrounding air.

[0039] The presence of a lid prevents the continuous diffusion of the essential oil solution's odor to the outside when the system is not in use.

[0040] According to a particular embodiment, the portable essential oil diffusion system for one user according to the present invention is equipped with a nebulizing device arranged to cooperate with at least one removable and / or refillable reservoir comprising an essential oil solution. Said nebulizing device comprises an electronic board connected to at least one power supply and to at least one piezoelectric element, which includes a central micro-perforated membrane and a periphery encapsulated in a circumferential seal fixed in the inner light of a housing. Said at least one central micro-perforated membrane comprises a first outer surface arranged to be in contact with the surrounding air, and a second inner surface arranged to be in contact with at least one capillary of a reservoir.said at least one removable and / or refillable reservoir comprises a storage space for an essential oil solution provided with a cavity having at least one opening and at least one capillary comprising a first end arranged to be in contact with said second lower surface of said micro-perforated central membrane and a second end in contact with said at least one opening of said cavity of said reservoir.

[0041] According to this particular embodiment, at least one removable and / or refillable reservoir comprises, on the one hand, a storage space for an essential oil solution provided with a cavity having at least one opening, and on the other hand, at least one capillary in the cavity comprising a first end arranged to be in contact with said second lower surface of said central micro-perforated membrane and a second end in contact with said at least one opening of said cavity of said reservoir, which allows the user to interchange the aroma and the essential oil solution from one use to another, while maintaining the sealing of the device according to the invention.

[0042] Preferably, at least one piezoelectric element of the portable essential oil diffusion system according to the present invention vibrates at a frequency between 20 kHz and 10 MHz, preferably between 30 kHz and 9 MHz, preferably between 40 kHz and 8 MHz, more precisely between 50 kHz and 7 MHz, more particularly between 60 kHz and 6 MHz, advantageously between 70 kHz and 5 MHz, more advantageously between 75 kHz and 4 MHz, even more advantageously between 75 kHz and 3 MHz, preferably between 75 kHz and 2 MHz, preferably between 75 kHz and 1 MHz, more precisely between 75 kHz and 900 kHz, more particularly between 75 kHz and 800 kHz, advantageously between 75 kHz and 700 kHz, more advantageously between 75 kHz and 600 kHz, even more advantageously between 75 kHz and 500 kHz, preferably between 75 kHz and 400 kHz,preferably between 75 kHz and 300 kHz, more precisely between 75 kHz and 200 kHz, even more advantageously between 75 kHz and 190 kHz, preferably between 80 kHz and 180 kHz, preferably between 90 kHz and 170 kHz, advantageously between 100 kHz and 160 kHz, more advantageously between 100 kHz and 150 kHz, even more advantageously between 100 kHz and 140 kHz, preferably between 100 kHz and 130 kHz, more preferably between 100 kHz and 120 kHz, for example at a frequency of 110 kHz.

[0044] Preferably, the central micro-perforated membrane of the portable essential oil diffusion system for one user according to the present invention comprises a series of micro-perforations with diameters between 1 and 40 µm, preferably between 1 and 35 µm, preferably between 1 and 30 µm, advantageously between 1 and 25 µm, more advantageously between 1 and 20 µm, preferably between 1 and 15 µm, even more advantageously between 1 and 10 µm, for example a series of micro-perforations with diameters of 2 µm, 3 µm, 4 µm, 5 µm, 6 µm, 7 µm, 8 µm, 9 µm, and combinations thereof.

[0045] It has appeared according to the present invention that the vibration of the piezoelectric element at a frequency between 75 and 190 kHz and more particularly at about 110 kHz associated with a series of micro perforations with a diameter between 1 and 40 pm, more particularly between 1 and 10 pm, makes it possible to nebulize the essential oil solution, pure or diluted, to a particle size particularly suited to nasal olfaction.

[0046] Advantageously, at least one piezoelectric element connected to said electronic board of the portable essential oil diffusion system for one user according to the invention, exhibits an adjustable oscillation between a first activated state and a second off state.

[0049] This makes it particularly advantageous to provide the user with the impression of continuous essential oil diffusion while limiting the use of the piezoelectric element, energy consumption and essential oil consumption.

[0050] Furthermore, it was shown that the synergistic combination of a piezoelectric element vibrating at approximately 110 kHz, or precisely at 110 kHz, with an activation cycle comprising a first activated state of 5 ps and a second off state of 95 ps, made it possible both to give the visual impression of continuous diffusion, to avoid overheating of the piezoelectric element, to avoid burning the essential oil and was particularly suited to the expectations of users.Furthermore, in the event that the user desires a higher intensity of essential oil diffusion, the diffusion device according to the present invention will maintain the predetermined duration of the first activated state of the piezoelectric element, for example 5 s, and decrease the predetermined duration of the second off state, for example the transition from 95 ps to 70 ps, ​​which will allow the diffusion intensity to increase, while limiting the overheating of the piezoelectric element, burning the essential oil and still giving the user the visual impression of continuous diffusion.

[0067] Other features, details and advantages of the invention will become apparent from the description given below, by way of non-limitation and with reference to the drawings and examples.

[0071] Figure 4 shows the portable essential oil diffusion system according to the invention with the removable reservoir in the mounted state, seen from the side.

[0072] Figure 5 shows a cross-sectional view of the nebulizing device of the system according to the invention, with the reservoir in the mounted state.

[0073] In the figures, identical or analogous elements bear the same references.

[0074] Figures 1 and 2 represent the portable essential oil diffusion system 1 for one user comprising a nebulizing device 2. Figures 3 and 4 represent the portable essential oil diffusion system 1 for one user comprising a nebulizing device 2 which cooperates with a removable and / or refillable reservoir 3 (shown in cross-section in Figure 5) which contains a pure or diluted essential oil solution.

[0075] The nebulizing device 2 according to the invention comprises a piezoelectric element 4 connected to an electronic board, and which includes a central micro-perforated membrane 5 and a perimeter 6 which is hermetically encapsulated in a circumferential seal 7 allowing fixation in the inner light of a housing 8. In addition, the central micro-perforated membrane 5 has two surfaces opposite each other, the first outer surface 9 is in contact with the surrounding air in order to allow the diffusion of the essential oil, and the second inner surface 10 is in contact with a capillary 11.

[0076] The reservoir 3 includes a storage space 12 for an essential oil solution, being a cavity 13 in which the solution is located, with an opening 14 giving access to the piezoelectric element 4, in particular to the second inner surface 10 of the central micro-perforated membrane 5. The reservoir also includes the capillary 11 in direct contact with the essential oil solution in the storage space 12.

[0077] The capillary 11 has two ends; the first end 15 is in contact with the second inner surface 10 of the central micro-perforated membrane 5, and the second end 16 is in the cavity 13 of the storage space 12 of the reservoir 3 containing the essential oil solution. Thus, the capillary 11, being in direct contact between the central micro-perforated membrane 5 and the essential oil solution in the storage space 12 of the reservoir, allows the essential oil solution to be conveyed to the piezoelectric element 4, through the opening 14 of the cavity 13, for nebulization and diffusion near the user's nose.

[0078] As illustrated in Figure 5, a spring 26 is located in the cavity 13, with the capillary 11 which is made of absorbing material and positioned between the spring 26 and the piezoelectric element 4, to ensure that the absorbing material remains in contact with the second inner surface 10 of the central micro-perforated membrane 5.

[0079] The reservoir 3 also includes a securing element 23 for securing the reservoir 3 within the inner lumen of the housing 8 to the capillary 11 in contact with the second inner surface 10 of the central micro-perforated membrane 5. This securing element 23 is an annular securing element surrounding the reservoir 3. It includes two locking lugs 24 which are arranged to cooperate with two notches (not visible in the figures) in the inner lumen of the housing 8. The locking lugs 24 are housed in the notches by an insertion and / or rotation movement, thus holding the securing element 23 within the inner lumen of the housing 8, securing the reservoir 3 there.Furthermore, the housing 8 of the nebulizing device 2 according to the present invention includes a light in which the piezoelectric element 4 is fixed, making accessible to the surrounding air only the first outer surface 9 of the central micro-perforated membrane 5, on the other side of this membrane 5, at the level of the second inner surface 10, at least one capillary 11 of the reservoir 3 is in direct contact in order to convey the essential oil solution from the storage space 12 of the reservoir 3 by capillarity, and the reservoir 3 acts as a sealing plug in order to close the housing 8.

[0080] To prevent the continuous diffusion of the odor of the essential oil solution to the outside when the system is not in use, the nebulizing device also includes a cover 25. This cover 25 is shown in the closed position in Figures 3 and 5, covering the first outer surface 9 of the central micro-perforated membrane 5 of the piezoelectric element 4. In the open position (not shown in the figures), the cover 25 allows the first outer surface 9 to be in contact with the surrounding air.

[0081] Furthermore, although not shown in the figures, the reservoir 3 also includes a lid, for example made of aluminum, which covers the capillary 11 and the opening 14 of the cavity 13, thus creating a sealed reservoir before use. In addition, the nebulizing device 2 includes a means for opening and / or drilling the second lower surface 10 of the central micro-perforated membrane 5 so as to open and / or drill this lid when the reservoir 3 is in contact with the nebulizing device 2, allowing the essential oil solution to reach the second lower surface 10 via the capillary 11 when the reservoir is in use.

[0082] In addition, and in a particularly synergistic way, the piezoelectric element 4 and more precisely the central micro-perforated membrane 5, vibrates at a frequency between 75 and 190 kHz, more precisely around 110 kHz, associated with a series of micro-perforations with a diameter between 1 and 40 m, more precisely between 1 and 10 m, allows the essential oil solution, pure or diluted, to be nebulized to a particle size particularly suited to nasal olfaction.

[0083] Furthermore, it was highlighted that the synergistic combination of the piezoelectric element 4 vibrating at approximately 110 kHz, with an activation cycle comprising a first activated state of 5 ps and a second off state of 95 ps, made it possible both to give the visual impression of continuous diffusion, to avoid overheating of the piezoelectric element, to avoid burning the essential oil and was particularly suited to the expectations of users.

[0084] The housing 8 comprising the nebulizing device 2 and the reservoir 3 associated with the capillary 11 is mounted on a support 18 such as an adjustable arm 19.

[0085] The steerable arm 19 is movablely attached to a control body 20 which includes a control interface 17, itself connected to the piezoelectric element 4 by means of the electronic board. The control interface 17 can be local as shown in Figure 2 and / or remote, and includes a means for switching the system 1 on and off, a Bluetooth pairing means, a means for managing the power and / or activation time of the piezoelectric element 4, a means for monitoring the autonomy of the system 1, and indicator lights such as LEDs.

[0086] In contrast to the control body 20, the portable essential oil diffusion system 1 according to the invention includes a battery body 22 which houses the power supply such as a rechargeable battery via a connector having a capacity between 100 and 1000 mAh, connected to the electronic board.

[0087] Finally, a flexible and adjustable band 21 connects the control body 20 to the battery body 22 to form an example of an embodiment of the portable essential oil diffusion system 1 according to the invention, allowing it to be placed and worn around the user's neck to enjoy aromatherapy without disturbing those around them, while having targeted and optimized diffusion at the level of their nose by olfaction.

[0088] In addition, the heavy neck headband 21 and / or at least one control body 20 and / or at least one battery body 22 of the portable essential oil diffusion system 1 for a user according to the present invention includes at least one shoulder, arranged to rest on a part of the shoulder or even the clavicle of a user, thereby enabling the system according to the present invention to rest stably around the neck, more precisely on the back of the user's neck as well as on his / her shoulder(s) or even his / her clavicle(s).

[0089] Furthermore, by resting stably around the neck, more precisely at the back of the user's neck and on their shoulder(s) or even collarbone(s), the adjustable arm 19 carrying the nebulizing device 2 can be easily moved to direct the diffusion of the essential oil towards the user's nose, advantageously at a distance of less than 50 cm from the user's nose, preferably less than 30 cm from the user's nose, preferably less than 20 cm from the user's nose, and even more advantageously less than 10 cm from the user's nose. Thus, according to the present invention, the diffusion of the essential oil solution occurs as close as possible to the user's nose, in a targeted and localized manner, without disturbing their surroundings or interfering with their mouth.

[0090] This advantageously allows for the provision of a nebulizing device 2 and more specifically a system 1 which operates autonomously and is portable for a user in order to provide local diffusion close to the user's nose.

[0091] Thus, the device according to the invention allows the user to benefit from the advantages of nebulizing essential oils in a localized manner directly near their nose, thereby greatly reducing the necessary dose while maintaining effectiveness, and advantageously without disturbing those around them.

[0092] In addition, the removable and / or refillable reservoir 3 allows the user to interchange the aroma and essential oil solution from one use to another or to refill the storage space 12 with an essential oil solution, while maintaining the sealing of the device according to the invention.

[0093] Thus, the portable essential oil diffusion system 1 according to the present invention can be activated on demand by the user, providing a direct and targeted diffusion towards the user's nose in order to avoid disturbing those around them, while providing an economical device, whose energy and essential oil consumption is optimized and finally avoiding unwanted drips or leaks.

[0094] It is understood that the present invention is in no way limited to the embodiments described above and that many modifications can be made to it without departing from the scope of the attached claims.
