Description

Scent delivery device
The present invention relates to a scent delivery device, comprising an aromatic source and ventilation means which are able and adapted to generate a forced airflow, wherein the aromatic source comprises a reservoir for receiving a scent substance therein, which reservoir is in open communication with an outlet at which, at least during operation, the scent substance escapes into the airflow.
Such a scent delivery device is increasingly finding application in public or other spaces for the purpose of creating a more pleasant environment therein by stimulating the olfactory organs. Particularly the disappearance of cigarette smoke as aromatic blanket in public spaces due to legal smoking bans has resulted in a need to provide an alternative background fragrance in order to obscure possibly present bodily odours perceived as penetrating. In addition, a scent delivery device of the type described in the preamble can provide a useful aromatic support to a setting, image or advertising message created in order to positively enhance, or at least influence in a desired manner, the mood of a target group.
Known scent delivery devices have the drawback however that the scent delivered thereby is not infrequently itself perceived as penetrating and unpleasant The only alternative in such case is to deactivate the device, although this is not in itself a satisfactory solution.
The present invention has for its object, among others, to provide a scent delivery device which does not have this drawback, or at least does so to significantly less extent, and which will therefore result in a higher degree of acceptance.
hi order to achieve the stated object a scent delivery device of the type described in the preamble has the feature according to the invention that the ventilation means are electronically controllable and that dosing means are provided which are able and adapted, at least during operation, to limit a maximum quantity of the scent substance delivered at the outlet. Both the airflow and the scent delivery are thus controllable and adjustable in the device according to the invention. It has been found, surprisingly, that with these parameters the device can be adjusted sufficiently precisely so as to create in practically any situation a desired scent pattern around the device. By decreasing or increasing the airflow the delivered scent substance penetrates less far or, conversely, further into a surrounding space and a mainly local or widespread scent perception will be created. The dosing means will here maintain a maximum momentary concentration in the space which is always below an accepted maximum, so that the scent is nowhere perceived as intrusive. The scent delivery device according to the invention can thus always be adequately adjusted in order to enable a precise response to the requirements of an actual situation.
For the purpose of an accurate and reproducible adjustment of the device a preferred embodiment of the scent delivery device according to the invention has the feature that at least one of the ventilation means and the dosing means is microprocessor- controlled by a microprocessor unit, and that the microprocessor unit is manually adjustable. A setting of the microprocessor can here be modified as required for the end user by a service engineer, or optionally carried out by the end user him/herself.
In a particular embodiment the scent delivery device according to the invention is characterized in that the reservoir comprises an inlet which is in open communication with an outlet of pump means for the purpose of receiving a pump pressure therefrom, and that the dosing means are able and adapted to electronically control the pump pressure of the pump means. The device herein has pump means which create an airflow through the reservoir and herein force the scent outside via the outlet. Control of the pump pressure provides a controllable dosing of the scent substance to the outlet in an exceptionally practical though no less effective manner. The container here particularly comprises an atomizer which forms a fine mist or aerosol from the scent substance and disseminates it into the surrounding area at the outlet.
Operation of the device for determined intervals usually suffices, and fully continuous operation is undesirable since an unnecessarily large amount of scent substance will thereby be consumed or satiation in the scent perception can occur among the public. In order to obviate both of these drawbacks, a further preferred embodiment of the scent delivery device according to the invention has the feature that clock means are provided which are able and adapted, on the basis of a time schedule adjustable therein, to activate or deactivate the device.
A particularly practical embodiment of the scent delivery device is characterized according to the invention in that at least the controllable ventilation means and the aromatic source with the dosing means are accommodated in a shared housing. At least the main components of the device are here accommodated in a shared housing, which facilitates installation thereof and is also aesthetically advantageous in those cases where the device is disposed in visible manner. In order to prevent misuse and vandalism, a further particular embodiment of the scent delivery device according to the invention herein has the feature that the housing is closable with lock means.
A further preferred embodiment of the scent delivery device according to the invention is characterized in that the reservoir is provided in a releasable container which is provided with an inlet which can be inserted into an outlet of pump means, wherein the container comprises the outlet. The releasable container herein provides for an exceptionally simple refilling in that an empty container simply need only be exchanged for a full one. A scent substance can thus also be easily exchanged for another. An empty container can be discarded as disposable article or, if desired, be refilled.
In order to enhance a correct positioning of a container in the device, a further particular embodiment of the scent delivery device according to the invention has the feature that an outer form and dimensioning of the container and an inner form, placing and dimensioning of a receiving element provided for this purpose in the device are specifically adapted to each other for the purpose, when the container is placed in a chamber, of aligning a pressure inlet of the container with the outlet of the pump means. An end user will thus also always be able to place the container correctly in the device. A further embodiment of the scent delivery device according to the invention is here more particularly characterized in that the container comprises a substantially hollow plastic body.
The invention will now be further elucidated on the basis of an exemplary embodiment and an associated drawing. In the drawing: figure 1 shows a view of an exemplary embodiment of a device according to the invention with a pivotable access door.
The figures are here schematic and not drawn to scale. Some dimensions in particular may be exaggerated to greater or lesser extent for the sake of clarity.
The device of figure 1 comprises an impact-resistant housing 1 which in this example takes a relatively robust form but which can in some cases be given a more decorative and aesthetically more powerful form. For the housing use is predominantly made in this case of preserved steel, although a suitable plastic or even wood can also be chosen instead.
The housing provides space for a fan 2 for generating a forced airflow and a container 3 having therein a reservoir for an aromatic liquid. In this example the container is fully releasable from the device and comprises a hollow body with sufficient volume to deliver a sufficient quantity of scent for a longer period of time. In this example the container is formed wholly from plastic, for instance transparent polypropylene, although other materials are also suitable for this purpose.
The scent substance is driven out of container 3 during operation under the influence of a pump pressure applied by means of pump means 5 provided for this purpose. An outer form and dimensioning of the container on the one hand and of a receiving element in the form of a bracket 6 provided therefor in the device on the other are adapted to each other such that a pressure inlet 7 of the container corresponds precisely with an outlet 8 of the pump means so that pressure inlet 7 of the container is inserted into outlet 8 of the pump when the container is placed. On a cover 4 the container 3 comprises an outlet 41 which is in open communication with an atomizer or nozzle 40 located thereunder. The air pressure produced by pump 5 is guided from pressure inlet 7 through nozzle 40 and, owing to a venturi action in the nozzle, entrains scent liquid from the reservoir into container 3. A riser tube 43 in the container herein provides for an uninterrupted supply of scent substance in nozzle 40 until container 3 is empty. The nozzle in turn forms a fine mist of the liquid and delivers this into a cavity inside convex cover 4. An extension pipe 41 guides the mist therefrom to outlet 42 of the container, at which the aromatic mist then escapes and is entrained by the airflow provided by fan 2.
Container 3, with the scent substance and nozzle 40-43, forms an aromatic source and is provided according to the invention with dosing means in that use is made of a pump 5 with an electronically controllable pump pressure. The pump is actuated for this purpose by a microprocessor 10 which also controls a rotation speed of fan 2. Microprocessor 10 can be adjusted by the user or a service engineer by means of a number of control buttons 11-13 so that the maximum dosage of the scent substance at outlet 42 of source 3 and the force of the airflow of fan 2 are particularly finely adjusted to a scent pattern to be created therewith in the surrounding space.
The microprocessor further comprises clock means for the purpose of activating or deactivating the whole device or a part thereof for determined time intervals on the basis of an input time schedule, so as to also have the delivered scent pattern respond precisely in this respect to the wishes of the user and prevent scent satiation and unnecessary consumption of scent substance.
An electric power supply to the device is provided by an electric power source (not shown). In this case this is a power source with an output voltage of about 12 V direct voltage. This power supply can be provided internally by means of for instance an accumulator or set of batteries, or obtained externally from a mains electricity network, hi this latter case an internal or external adapter/rectifier provides for the required voltage reduction and rectification. Control LEDs (not shown) provide continuous insight into the status of the device. The device is closable by means of a door 20 which is shown separately in the figure but which in practice is mounted pivotally in housing 1 by means of eyes 21 provided thereon. For this purpose eyes 21 are folded to the rear round the indicated fold line and mounted rotatably in the housing. The door can be closed by means of lock means 22 and an appropriate key in order to prevent misuse, theft of the container or other vandalism.
Although the invention has been further elucidated above on the basis of only a single exemplary embodiment, it will be apparent that the invention is by no means limited thereto. On the contrary, many variations and embodiments are still possible within the scope of the invention. The dosing means of the aromatic source can thus also comprise an optionally electronic valve. A controllable pump as in the example does however have the advantage that, except for the pressure inlet, no further connections are required for electronic dosing of the outlet of the container.
A control of the fan and of the pump means or other dosing means is realized in the exemplary embodiment using a programmable digital microprocessor, although use can also be made instead of an analog control, for instance a resistance circuit on the basis of one or more controllable resistances. A clock function can be provided both internally and externally and take a digital as well as analog form using appropriate capacitance values of capacitors provided for this purpose, in particular so-called varicaps, and resistance values.
The device can be disposed on its own in a space but, if desired, can also be added to an air duct of an existing ventilation system or air-conditioning system.
