  • the present invention relates to a fragrance delivery device comprising a chamber having a first circular aperture and an actuator for forcing air from said chamber through said aperture to form a vortex comprising said fragrance.
  • the present invention further relates to a method of delivering a fragrance from such a device.
  • Fragrance dispensing is commonplace in modern society. Many applications can be thought of, ranging from toilet fresheners to entertainment devices dedicated to providing someone with an olfactory sensation, e.g. in combination with image delivery, e.g. television including olfactory stimulus generation. An example of the latter can for instance be found in the paper "Pulse Ejection Technique of Scent to Create Dynamic Perspective" by Junta Sato et al., which can be retrieved from the Internet at
  • dispenser/diffusers for example, ultrasonic dispensers, perfume burners, aromatic candles and aromatic tissues.
  • Such devices suffer from a number of problems. Because of their poor directionality, they are unsuitable for targeted fragrance delivery, i.e. the delivery of a fragrance to an individual in a specific location. Moreover, as such devices have to rely on diffusion of the fragrance to create the intended olfactory sensation in a large volume, e.g. a room, large quantities of the fragrance have to be used, which not only adds to the cost of the device as such fragrances can be expensive, but also limits the active life of such devices. In order to deliver a fragrance to a target destination rather than a random distribution of the fragrance by diffusion principles, the fragrance- laden air may be generated in the form of a ring vortex. An example of such a device is for instance known from US 6,536,746.
  • scent vortex generating devices have an improved directionality, they are not without problems.
  • the size of the device has to be increased. This is because the distance D a single vortex can travel before it disintegrates is typically governed by the empirical formula:

  • a fragrance delivery device comprising a chamber having a first circular aperture and an actuator for forcing a fluid from said chamber through said aperture to form a vortex comprising said fragrance, wherein the device is adapted to generate a coalescent train of said vortices.
  • the present invention is based on the realization that the theoretical limit of vortex propagation can be extended by the generation of a coalescent train of vortices, i.e. a pattern of positive interference between such vortices, which improves directionality as well as propagation distance of each vortex.
  • This facilitates a miniaturization of the device, thus improving its applicability in application domains requiring a small form factor, e.g. for aesthetic reasons, and reducing the amount of fragrance to be added to each vortex due to the smaller size of the vortices compared to prior art fragrance vortex generating devices.
  • the actuator is a piezo element or a loudspeaker.
  • typical inner dimensions of said chamber preferably are in the range of 1-5 cm to optimize the quality of the generated vortex.
  • Preferable size of the aperture is in the range of 1-10 mm.

  • the first and further apertures are located in a sidewall of said chamber connecting opposite surfaces of said chamber, the actuator being located in one of said surfaces and arranged to force the fluid in the direction of the opposite surface.

  • a particularly powerful vortex can be generated by periodically disrupting a circulation, i.e. backflow, from and to the inner compartment through the outer compartment, whereby the disruption forces the vortex generated at the aperture through the further opening.

  • a fragrance delivery device 1 comprises a chamber 10 which has an aperture 12 in an exit surface and an actuator 20 in an opposite surface.
  • the actuator 20 may for instance be a mechanical actuator, e.g. a diaphragm of a loudspeaker, a piezo element and so on.
  • the actuator 20 is controlled by a controller (not shown), which is configured to control the actuator 20 such that the fluid inside the chamber 10 is harmonically vibrating.
  • the fluid will be regularly referred to as air although it should be understood that any suitable gaseous fluid may be used as the medium inside the chamber 10.
  • the controller is adapted to actuate the actuator 20 in a pattern that causes the generation of a train of partially spatially overlapping ring vortices 30 from the aperture 12, which preferably is a circular aperture having rounded edges as this promotes the formation of stable ring vortices.
  • the train of ring vortices 30 (or parallel trains of vortex pairs) forms a coalescent pattern, i.e. a pattern in which the vortices 30 positively interact with each other via fluid flows that results in increase of stability and directionality of the vortex train.
  • a slight overpressure zone exists in front of the vortex, which can destabilize a single vortex.
  • the preceding vortex reduces this overpressure, resulting in further increase of vortex stability and directionality of entire train.
  • This can be seen as a tidal wave of vortices 30 propagating in a controlled direction.
  • Such a tidal wave can be generated by accurately controlling the actuation frequency of the actuator 20 and the dimensions of the aperture 12. Consequently, a fragrance jet is formed in which the fragrance remains contained in the vortices 30 until they disintegrate, such that all fragrance can be delivered to the target area without significant losses, e.g. through diffusion, along the way.
  • the amount of fragrance to be delivered to the target area can be accurately controlled by the coalescent train of ring vortices 30.
  • the fragrance experience for a (human) target can be effectively terminated by disabling the actuator 20, which causes the rapid dissipation of the already expelled fragrance by means of diffusion due to the fact that the termination of the tidal wave stops the propagation of the fragrance towards the target and the concentrations of the fragrance in the air rapidly drop below (human) perception levels.
  • This therefore also facilitates the delivery of precise amounts of the fragrance to the target, as the amount of fragrance per vortex 30 is well-defined, and the number of vortices 30 delivered to the target can be accurately controlled by controlling the duration of the coalescent train at a well- defined frequency of vortices per second.
  • the chamber 10 will typically be refilled with the air expelled in the form of a vortex 30 by a back draft through the aperture 12.
  • a back draft can destabilize a vortex 30 and reduce the amount of kinetic energy stored in the vortex.

  • the fragrance delivery device 1 may comprise an additional or auxiliary chamber 40. This is shown in FIG. 2.
  • the auxiliary chamber 40 is in fluid communication with the chamber 10 to replenish the air (or alternatively gaseous fluid) in the chamber 10 in between subsequent generations of the vortices 30. This reduces or even cancels the back draft through the aperture 12 after generation of a vortex 30.

  • the auxiliary chamber 40 is designed to displace a volume of fluid larger than the volume of the chamber 10 into the chamber 10, which has the technical effect that a portion of the displaced fluid is forced out of the chamber 10 through the aperture 12, thus providing an additional propulsion, i.e.

In a disengaged state, the actuator 130 allows a recirculation of air driven by the fan in the opening 114. This is shown in the top pane of FIG. 4. The air is forced out of the inner compartment through the aperture 112, but sucked back into the inner compartment 110 by the fan through the outer compartment 120 and the opening 114.
