Description

OLFACTORY DEVICE/SYSTEM

DESCRIPTION

The present invention relates to an olfactory device/ system for releasing a functional fragrance or mixture into an environment. The present invention also relates to an olfactory system comprising a plurality of olfactory devices.

With the term functional fragrance, we intend all that category of health and experiential products able to activate the brain plasticity of a user to obtain psychophysical benefits. The benefits that can be obtained in the health field can be for example neurophysiological, in the experiential field can be for example the reduction of stress, the reduction of anxiety, the increase of concentration.

Another type of functional fragrance is used in the field of sanitation to reduce and/ or eliminate viruses, bacteria, and mould.

The term environment can be used to mean a home, shop, or other closed environment for domestic, public, commercial, health and similar purposes.

The term mixture refers to a mixture of functional fragrances or other products such as sanitiser or sanitary products.

To date, several devices are known for releasing fragrances or mixtures into the environment. However, these devices have several disadvantages which will be discussed below.

Disadvantageously, the known devices are not able to regulate the level of saturation of the functional fragrance or blend in the environment thus leading to an overdose and possible waste of the product in question.

In addition, some of the known devices are not able to operate autonomously considering this saturation level.

A further disadvantage arises from the use in the field of sanitisation, as there are currently machines which only reach saturation and stop.

Olfactory devices of the type described above are known from document US2016/339136 and document US 2019/216967, wherein the device, or a system of a plurality of devices, varies the concentration of functional fragrance until reaching saturation, in particular said saturation is detected by means of some environmental sensors of physical quantities of the same environment.

A technical task of the present invention is therefore to provide an olfactory device/ system capable of overcoming the drawbacks of the prior art.

It is therefore an object of the present invention to provide an olfactory device/ system that avoids product wastage.

A further scope of the present invention is therefore to provide an olfactory device/ system which allows for automation to ensure efficient use and consumption of the functional fragrance or blend.

A further scope of the present invention is to provide an olfactory device/ system which can achieve efficient and continuous sanitisation.

A further scope of the invention is to provide an olfactory device/system that is structurally entirely reliable.

It is a further scope of the invention to provide an olfactory device/system that is functionally entirely reliable.

It is a further scope of the present invention to provide an olfactory device/ system that is simple and/ or inexpensive to manufacture.

It is a further scope of the present invention to provide an olfactory device/ system that is cost-effective.

It is a further scope of the present invention to provide an olfactory device/ system that is industrially feasible. A further scope of the present invention is to provide an olfactory device/ system that is alternative and/ or improved with respect to conventional solutions.

A further scope of the present invention is to provide an olfactory device/ system that has an alternative and/or improved configuration, both in terms of construction and function, compared to conventional solutions.

The specified technical task and the specified purposes are substantially achieved by an olfactory device/system comprising the technical features set forth in one or more of the appended claims. The dependent claims correspond to possible embodiments of the invention.

Further features and advantages of the present invention will become clearer from the indicative, and therefore non-limiting, description of a form of embodiment of an olfactory device/ system.

With reference to the atached figures, with 1 has been overall indicated an olfactory device/system for the release of a functional fragrance or mixture in an environment "A" which, for simplicity of description, will be hereinafter indicated as olfactory device/system 1.

With the term functional fragrance, we intend all that category of therapeutic products that can directly influence and activate the biochemistry of a user to bring him to a mental state of calm and concentration. In particular, the term functional fragrance refers to all those health and experiential products that can activate the brain plasticity of a user to obtain psychophysical benefits. The benefits that can be obtained in the health field can be for example neurophysiological, in the experiential field can be for example the reduction of stress, the reduction of anxiety, the increase of concentration.

The term "A" environment can be understood as a home, shop, or other closed environment for domestic, public, commercial, health and similar use.

Advantageously, the olfactory device according to the invention comprises at least one containment structure 100, internally hollow and defining a containment compartment 101.

Appropriately, the device 1 according to the invention has small dimensions, i.e. it has dimensions suitable to be arranged within any environment, be it industrial and/or domestic without generating cluter.

For example, the containment structure 100 of the device 1 is configured to be arranged above a shelf, for example a table, in a simple manner, also allowing the user to use the table for other purposes.

The olfactory device/system 1 comprises a plurality of environmental sensors, housed within the containment compartment 101 of the containment structure 100 and configured to detect environmental parameters from the environment, and a dispensing device/ system, at least partially housed within the containment compartment 101, and comprising a housing 2a in which at least one functional fragrance or blend is stored.

Preferably, the housing 2a is shaped to define several compartments in which to hold specific functional fragrances or mixtures and mixing means for mixing (if necessary) different functional fragrances or mixtures as required, as will become clearer from the remainder of the present description.

In other words, the housing 2a comprises a plurality of compartments, advantageously formed within the containment structure 100, each containing a specific functional fragrance or blend and mixing means configured to mix functional fragrances and/or blends with each other.

The dispensing device 2 preferably comprises a pump 2b, housed within the containment structure 100, connected or connectable to a filtered air inlet "F", preferably formed on a side wall 102 of the containment structure 100, and configured to pressurise the housing 2a so as to release via a dispenser 2c the functional fragrance or mixture into the environment "A".

The olfactory device 1 comprises a processing unit 3, housed within the containment compartment, electronically connected with the plurality of environmental sensors and configured to receive and process environmental parameters in order to identify an amount of functional fragrance or mixture to be dispensed.

In this way, the processing unit 3 can send an actuation signal to the dispensing device 2 to dispense a specific functional fragrance or mixture in the environment "A".

In other words, depending on the actuation signal, the processing unit 3 enables control of the pump 2b of the dispensing device 2 so as to put the housing 2a under pressure and implement, depending on the processed environmental parameters, the mixing means if necessary so as to obtain the desired mixture to be dispensed.

Furthermore, depending on the measured and processed environmental parameters, the actuation signal allows the activation of the mixing means of the housing 2a to obtain the suitable mixture to be released into the environment.

Furthermore, the device according to the invention is compact, extremely manageable, with reduced overall dimensions and easily usable and transportable by the end user, who can store it in any environment he wishes to treat with the functional fragrance.

The above plurality of environmental sensors comprises at least one olfactory sensor 4a, at least one temperature sensor 4b, at least one humidity sensor 4c and at least one atmospheric pressure sensor 4d.

The olfactory sensor 4a is configured to measure a concentration of functional fragrance or mixture in the environment "A", whereby the processing unit 3 is configured to send a further actuation signal to the dispensing device 2 if the measured concentration is below a predetermined threshold.

In other words, should it be apparent from a first dispensing that the functional fragrance or mixture is insufficient to scent or sanitise the environment "A", the olfactory device/ system 1 would further be configured to dispense a further amount of functional fragrance or mixture to adequately saturate the environment "A" according to the measured environmental parameters. In this way, uniform delivery of the functional fragrances or mixture can be achieved.

Preferably, the olfactory sensor 4a is a radio frequency identification sensor (RFDI) comprising a functional fragrance or blend sensitive material element, at least a humidity sensing portion in the environment and a cross-sectional radar diffuser (RCS) for detecting the functional fragrance or blend in the environment "A". Preferably, the olfactory device/ system 1 further comprises a communication system 5 configured to interact with a user interface device (not shown) to send the actuation signal via the processing unit 3 according to pre-set parameters or a real-time actuation selected via the user interface device.

In other words, the user interface device (such as a PC, smartphone, smartwatch or the like) may be used to set the parameters that will dictate the operation of the olfactory device/ system 1 or may be used to implement as needed the olfactory device/ system 1. Thus, a user can customize the operation of the olfactory device/ system 1 or implement the same at will. Preferably, the communication system 5 is further configured to send, via the user interface device, position parameters of the user in the environment "A" to the processing unit 3 so that the processing unit 3 sends the actuation signal according to a positioning of the user in the environment "A".

Preferably, the olfactory device/ system 1 is powered by means of a mains power supply or a battery 6.

In the light of the above, the device/ olfactory system 1 is able to change the concentration of certain functional fragrances in an environment "A" by interacting with it on the basis of information (the environmental parameters) that the device/ olfactory system 1 itself is able to acquire either on the basis of pre-set settings or on the basis of user input or on the basis of the device/ olfactory system l's own artificial intelligence.

The olfactory device/ system 1 (i.e. the processing unit 3) processes the environmental parameters measured via the sensors and, based on the pre-set parameters, provides an impulse to the dispensing device 2 which, via the pump 2b, goes on to put pressure on the housing 2a by diffusing the functional fragrance or mixture via the dispenser 2c

The olfactory device/system 1 (i.e. housing 2a) can accommodate several functional fragrances (or mixtures) with different characteristics. The user can choose the fragrance to be used via the synoptic screen or via remote control. The olfactory device/ system 1 via RFID can recognise the type of fragrance.

The fragrance concentration in the room is detected by the olfactory sensor 4a which closes the cycle by providing a signal again to the processing unit 3.

The olfactory sensor 4a allows the olfactory device/system 1 to adapt to the characteristics of the environment "A" itself and to measure the result obtained. In other words, the olfactory sensor 4a can accurately measure the fragrance concentration in each environment "A". The other sensors measure the other parameters of the working environment (temperature, humidity, and atmospheric pressure). Processing Unit 2 is now able to determine the required fragrance concentration for room "A" and thus control the release of fragrance into room "A" until the set concentration is reached.

Using the other sensors, it is also possible to detect anomalies in the measurements taken and send alarm signals to operators who can intervene and check the environment.

In addition, the alarm signals can be used to quantify the functional fragrances used and signal to the production and supply chains the need to send new stocks of functional fragrances to produce them when needed and avoid wastage.

The olfactory device/system 1 further comprises inputs (RFID or Bar Code or NFC or WIFI or Bluetooth) to be able to acquire other information from the environment (via the communication system 5).

Preferably, the olfactory device/ system 1 may be implemented in the form of a device that is placeable on a horizontal surface or placeable on a vertical surface.

Preferably, the olfactory device/ system 1 may be implemented in the form of a device that is portable or wearable by a user.

The present invention further relates to an olfactory system 10 for releasing a functional fragrance or blend in an environment "A" comprising a plurality of olfactory devices 1 as described above. Figure 2 depicts a generic environment "A" (e.g., a large room such as a conference room) in which four olfactory devices 1 are present.

The olfactory system 10 further comprises a remote data processing centre 11 communicating with each olfactory device/ system 1 so as to obtain functional parameters from each olfactory device/ system and process the functional parameters so as to send a control signal to each olfactory device/ system 1 depending on a saturation state of the environment "A".

Since each device/olfactory system 1 is provided with an olfactory sensor 4a, each device/ olfactory system 1 is configured to communicate with the remote data processing centre 11 if the measured concentration of functional fragrance or mixture in the environment "A" is below a predetermined threshold so as to dispense the amount necessary to reach the threshold.

Furthermore, the olfactory sensor 1 allows to communicate to the remote data processing centre 11 that the sanitisation effect has ended and that it is necessary to dispense again the functional fragrance or mixture in the environment.

The plurality of olfactory devices 1 and the remote data processing centre 11 are preferably configured to communicate with each other via cloud technology.

The remote data processing centre 11 is further configured to generate a log 12 of the functional parameters acquired by each olfactory device/ system 1.

By means of the log 12, the olfactory system 10 is able to send a report to a user for each sanitisation that has been carried out, allowing to obtain a certification on the sanitisation that has been carried out that is constant and not modifiable.

The remote data processing centre 11 is also configured to communicate with a user interface device to send an alarm signal if the functional parameters indicate a malfunctioning condition of one or more olfactory devices 1.

In other words, the olfactory system 10 comprises multiple olfactory devices 1 arranged in multiple environments A or in different portions of a single large environment A and alerting the remote data processing centre 11 about the need to intervene in that particular environment "A", based on the measured saturation state.

The remote data processing centre 11 also receives information from the olfactory devices 1 about the measurements acquired by the various sensors, about the type of fragrance in use on the particular device/ olfactory system 1 and about the identifier of the environment "A" in which the device/ olfactory system 1 is operating, in order to record the measured data and the operating conditions and to issue possible alarm signals to the operator for maintenance or control interventions or to communicate an emptying of one or more bays 2a.

The olfactory system 10 is therefore capable of keeping various "A" or large environments monitored and allows to control the air quality as well as to manage the needs of different users and provide appropriate supplies or technical interventions in case of anomalies. Advantageously, the present invention can overcome the drawbacks arising from the known art.

Advantageously, the present invention can improve the quality of life and the health and experiential well-being of people as well as improving health safety.

Preferably, the containment structure 100 is developed along a prevailing development axis Y between a support base 103 and a cap 104. Advantageously, the axis of prevailing development Y is substantially vertical.

Appropriately, the support base 103 delimits the containment volume inferiorly and the cap 104 delimits the containment volume 101 itself superiorly.

In accordance with the preferred embodiment form illustrated in the appended figures, the side wall 102 has a substantially cylindrical shape and more preferably has a cylindrical shape substantially convex in the centre. In particular, the side wall 102 is developed starting from the support base 103, widening until reaching a maximum transversal encumbrance and then narrowing until reaching again a substantially congruent encumbrance of the cap 104 with that of the support base 103.

Appropriately, the device according to the invention and with specific reference to Figures 4 - 6, comprises at least one electric motor 105 housed within the containment structure 100, preferably in proximity to the support base 103.

Advantageously, the side wall 102 of the containment structure 100 is provided with a through opening 106 made at the electric motor 105 and configured to allow a passage of cooling air from the outside to cool the same electric motor 105 during its operation. Appropriately, the device 1 according to the invention further comprises pumping means, operatively connected with the electric motor 105, and in particular comprising said pump 2b housed within the containment volume 101 of the containment structure 100.

Operationally, the pumping means are fluidically connected with the functional fragrance housing 2a and are configured to be activated by the electric motor 105 to compress the functional fragrance and atomise it towards the external environment A. In particular, the housing 2a is mounted within the containment volume 101 of the containment structure 100 and configured to contain a volume of functional fragrance. For this purpose, the device includes atomising nozzles 111 for passing the atomised fragrance.

Preferably, the nozzles 111 are aligned with corresponding further through openings 112 made on the side wall 102 of the containment structure 100.

The device 1 further comprises air passage means 107 rotatably mounted within the containment structure 100 in proximity to the hood 104. More in detail, the air passage means 107 are configured to allow a flow of air from the external environment to enter through the hood 104. For this purpose, the air passage means 107 include at least one fenestration made at the hood 104 and in particular an annular through-light 108, defined laterally between the hood 104 and an upper edge of the side wall 102, wherein the annular through-light 108 puts the external environment in communication with the containment volume 101 of the containment structure 100. The air passageway is operatively used to be mixed with a dose of nebulised functional fragrance, as described in detail below.

Preferably, the air passage means 107 comprise at least one suction conduit 110 formed in the containment structure 100 that connects the annular pass-through light 108 to the functional fragrance housing 2a.

In other words, the device allows air to enter from the light 108 during expulsion of the atomised fragrance through the nozzles 111. Suitably, the device comprises the above processing unit 3, which preferably comprises at least one PCB 109 electronically connected to the electric motor 105 and configured to drive the latter in rotation in a commanded manner.

Further, the electronic control unit 109, which is electronically connected to the sensors 4, in particular at least one relative humidity sensor.

The processing unit 3 is configured to calculate the amount (e.g. the mass) of functional fragrance dispensed at each activation of the pumping means.

Advantageously, said processing unit 3 is configured to calculate a comparison value, based on the amount of functional fragrance dispensed by said dispensing device 2.

Suitably, said olfactory sensor comprises at least one relative humidity sensor, configured to detect a relative humidity value of the ambient air A and send it to said processing unit 3.

Preferably, said processing unit 3 is configured to receive said relative humidity value from said olfactory sensor and compare it with said comparison value and correspondingly generate a command value to activate said dispensing device/ system 2.

Preferably, said processing unit 3 is configured to calculate a required humidity value based on comparing said relative humidity value of said environment A with said comparison value to reach said predetermined threshold.

Suitably, the relative humidity of environment A is substantially proportional to the concentration of functional fragrance in said environment A.

Preferably, in order to make the relative humidity of room A substantially proportional to the functional fragrance concentration in said room A, said predetermined threshold is a relative humidity value of said room A, equal to the difference between a humidity offset value of said room A and a pre-set saturation humidity value.

Advantageously, said predetermined threshold is calculated by said processing unit 3 based on a first measurement of relative humidity of said environment A before starting the dispensing of said functional fragrance.

In this way, the device according to the invention makes it possible to automatically vary the delivery of functional fragrance by directly measuring its concentration in the environment A in which it is positioned, obviating the drawbacks of the known technique mentioned above.

In accordance with a further embodiment, the olfactory sensor 4a further comprises at least one sensor of at least one chemical element and/ or compound present within the functional fragrance, in order to allow calculation of the comparison value directly based on the presence and/ or concentration of said chemical element and/ or compound in the environment A.

Advantageously, the predetermined threshold is set as a value slightly higher than the offset value, in order to allow for a deferred delivery of functional fragrance, in particular by decreasing the amount of persistent fragrance and obviating the risk of the fragrance being intrusive to any users.

Furthermore, preferably, the device comprises the aforementioned temperature sensor 4b and/ or a carbon dioxide sensor, which is also housed within the containment volume 101 and is configured to detect at least one ambient air temperature measurement A and/ or a carbon dioxide concentration.

Advantageously, the temperature and/ or carbon dioxide value is used by the processing unit in a manner analogous to the relative humidity value.

More in detail, the processing unit initially sets a temperature and/ or carbon dioxide offset value, substantially equal to the temperature value of the environment A prior to the start of the functional fragrance delivery.

Advantageously, the processing unit comprises a memory module in which a control algorithm is advantageously stored, whereby the processing unit 3 enables control of the dispensing device/ system.

Advantageously, the control algorithm enables binding of the change in temperature and/ or carbon dioxide with the change in functional fragrance concentration to be able to command fragrance delivery by activation of the delivery device.

Advantageously, the device comprises at least one acquisition path, obtained inside the containment volume, configured to be crossed by an air flow of the environment A from which to acquire at least the measurement of relative humidity and preferably also of temperature and/ or carbon dioxide.
