Definitions

  • the present invention is generally directed to an aroma diffuser and a method of using an aroma diffuser.
  • Aroma diffusers also sometimes known as aroma lamps, are used to diffuse aromas arising from scented liquids such as essential oils, and may be used as part of aromatherapy and otherwise to improve the aroma of a living space such as a living room or bedroom.
  • Aroma diffusers operate by diffusing scented liquids such as essential oils into the air by, for example: heating essential oils, allowing essential oils to naturally evaporate, or by nebulising essential oil I water mixtures whether by use of compressed air or ultrasonic methods.
  • a natural evaporation diffuser may be provided as simply as by placing rattan reed sticks (or similar) into a container of essential oil.
  • the porosity of the reeds provides forwicking activity and increased evaporation, thereby diffusing the aroma of an essential oil into a space.
  • Natural evaporation diffusers by nature operate more slowly and passively than more active diffuser arrangements, and can take time for aromas to become noticeable while providing low levels of aroma.
  • a heat diffuser increases the rate of evaporation by, for example, heating essential oils through placing a candle underneath a dish or bowl of essential oils. More sophisticated devices may provide electric resistance heating for controlled heating. Heating of the essential oils naturally increases the rate of evaporation and diffusion of the oils, thereby providing a more noticeable diffusion of aroma. However, it may also affect the chemical composition of the oils as they evaporate, thereby altering the resultant aroma.
  • a nebulisation diffuser operates by generating droplets of scented liquid (such as an oil-water mixture) to generate a mist for dispersion throughout a room.
  • a nebuliser diffuser may operate by for example applying a jet of compressed air though the scented liquid to generate droplets, or by subjecting the scented liquid to ultrasonic vibrations that in turn cause cavitation and generation of droplets.
  • Ultrasonic nebulisers generally provide the advantage of consistent droplet size and low-noise operation when compared to jet nebulisers.
  • US patent 9259497 in the name of Lui Lock Chak, discloses an evaporative-style aroma diffuser in which one or more fragrance containers are held in series within a retainer. Each fragrance container houses a fragrance substance held within a roll of absorbent paper and is configured to enable air to pass through the fragrance container. A fan or similar is used to blow air though the fragrance containers such that fragrance substance evaporates and passes into the air which is then discharged into a room or space.
  • US patent 9421295 in the name of Puzhen Life Co., Limited, discloses an aroma diffuser that generates mist through jet nebulisation.
  • the device of US 9421295 enables mixing of essential oils in adjustable proportions through use of multiple separate essential oil bottles.
  • the generated mist passes from the device through an upward facing diffusion outlet into a room or space.
  • US patent application 2002/00680023 in the name of Jorgensen discloses an aroma diffuser that generates mist through ultrasonic oscillation.
  • the ultrasonic oscillator generates high frequency sound waves and to cause atomisation of the aromatic fluid contained in the fluid container to produce a mist.
  • the breakup of fine droplets is seen emitted the transmissive cover and at the same time the device emits music and a mixed colour of light.
  • an aroma diffuser comprising: a housing comprising a mist outlet located in an upper surface of the housing, the housing containing: a liquid reservoir for storing a scented liquid; a mist generator for generating a mist of scented liquid, wherein the aroma diffuser further comprises a mist guide member configured to direct mist passing from the mist outlet to the outer perimeter of the mist guide member.
  • the mist guide member comprises a circular outer perimeter.
  • the mist guide member is substantially disc-shaped.
  • the mist guide member is located directly above the mist outlet.
  • the mist outlet is located within an upper recess in turn located in the upper surface of the housing.
  • the mist guide member is located at least partially within the upper recess. In a further embodiment, the mist guide member is located entirely within the upper recess.
  • the aroma diffuser is configured such that mist passes through a gap between the upper recess and the mist guide member.
  • the mist outlet comprises a mist guard, the mist guard further comprising a lower mist guard surface and a sidewall extending upward from the lower mist guard surface, wherein the sidewall comprises one or more apertures to allow mist to pass therethrough.
  • the lower mist guard comprises a convex lower surface.
  • the sidewall comprises apertures substantially along its entire perimeter.
  • the housing further comprises one or more internal baffles surrounding the mist outlet.
  • the mist generator comprises an ultrasonic oscillator.
  • the mist generator is located in the base of the liquid reservoir and is considered to generate mist within the liquid reservoir.
  • the liquid reservoir is configured to provide an open topped tank.
  • the housing further contains a battery for powering the aroma diffuser.
  • the housing comprises a base housing member and a cover housing member, the cover housing member detachably connected to the base housing member, such that the cover housing member may be removed to access the liquid reservoir.
  • the housing further contains a fan, the fan configured to blow mist out of the mist outlet.
  • the fan is further configured to circulate air to cool components located within the housing.
  • a method of using the aroma diffuser of the first aspect to diffuse an aroma into a space there is provided a method of using the aroma diffuser of the first aspect to diffuse an aroma into a space.

  • the aroma diffuser comprising: a housing further comprising a mist outlet, and a mist guide member configured to direct mist passing though the mist outlet to the outer perimeter of the mist guide member.
  • the exemplified aroma diffuser comprises a housing 1 , the housing 1 comprising a mist outlet 3 located in an upper surface of the housing 1 to enable mist generated by the aroma diffuser to pass from the device and be dispensed into a space such as a room.
  • a mist guide member 2 Above the mist outlet 3 is located a mist guide member 2, the mist guide member 2 configured to direct mist passing from the mist outlet 3 to the outer perimeter 23 of the mist guide member 2.
  • the scented liquid reservoir may comprise a reservoir frame 10 supporting the scented liquid reservoir 4 within housing 1.
  • a mist outlet would typically be provided as a single aperture located in an upper portion of an aroma diffuser (such as a nebulising aroma diffuser).
  • an aroma diffuser such as a nebulising aroma diffuser.
  • This configuration generally allows mist to be directed generally upward into a space to be diffused.
  • the present inventors have identified that such a configuration may not necessarily allow sufficiently fast and efficient dispersal of aroma, since natural flow (such as through Brownian motion) would be relied upon to diffuse about the space.
  • the present invention addresses this issue by providing a configuration that directs mist existing the aroma diffuser in more than one direction and, according to certain embodiments, in a 360-degree field about the aroma diffuser.
  • the mist guide member 2 may be generally disc shaped and may further include a slight raise from the centre to the perimeter 23 of the mist guide member 2.
  • the mist guide member 2 is positioned above the mist outlet 3 within a recess 22 located within an upper surface of the housing. This provides a more visually pleasing configuration (whereby the mist guide member is generally out of sight when the aroma diffuser is viewed from side-on) while also: affording the mist guide member 3 protection from knocks and falls; and enabling the mist to be directed in a somewhat upward direction for greater dispersion into a space and away from surfaces capable of being stained by a scented liquid, as for example where the recess includes an outer lip to direct the flow of mist. As exemplified, the mist guide member 2 is held above the mist outlet 3 by a mist guide member support 6.
  • the mist outlet 3 may be configured to provide a mist guard, the mist guard comprising a lower mist guard surface 7 and side wall 8 extending upward from the lower mist guard surface 7.
  • the side wall 8 includes one or more apertures 9 enabling mist to pass through the mist guard.
  • the lower mist guard surface 7 may provide a concave lower surface. It is believed that the mist guard serves to enable a more uniform mist of droplets to exit the aroma diffuser. That is, larger droplets thrown up by the nebuliser will be blocked by the mist guard so that they cannot exit the aroma diffuser.
  • mist does not exit the aroma diffuser from a single narrow aperture that may be caused to partially or completely block due to dust or similar small debris.
  • mist may exit the aroma diffuser from a number of locations and directions through the gap formed between recess 22 and the mist guide member 2, and via a number of apertures 9 in the mist outlet 3, decreasing the likelihood of any significant blockage.
  • the nebuliser 5 is provided as an ultrasonic oscillator provided at the bottom of an open topped scented liquid tank 4.
  • the ultrasonic oscillator causes cavitation in the above-located scented liquid which in turn causes mist to form above the liquid.
  • Other embodiments are contemplated where, for example, mist is generated by jet nebulisation or other forms of nebulisation.
  • a fan 14 which forces a flow of air through the aroma diffuser.
  • the flow of air is sucked from air inlet 20 into the scent diffuser passes by the top of the scented liquid reservoir 4 (via air flow path 21) so as to capture mist rising from the scented liquid reservoir and force it though the mist outlet 3.
  • the fan 14 also passes air past electronic components of the aroma diffuser so as to cool those components, as discussed in further detail below. In this way, the fan 14 may serve more than one purpose.
  • the fan 14 (as with other components of the aroma diffuser, including the exemplified nebuliser 5) is powered according to certain embodiments by a battery 12 such as a rechargeable battery.
