Definitions

  • the invention relates to a device for dispensing a fluid for fragrancing, deodorising or sanitising air. Particularly, the invention relates to an air freshening device incorporating a light .
  • Air freshener devices are commonplace, particularly in domestic environments where they are used to create a pleasant fragrance or mask a bad odour.
  • the devices are generally of two types, a stand-alone type which can be placed away from a mains socket and which may be electrically operated by means of an electrical lead or batteries, or the type which plugs directly in to a mains socket, known as a plug-in device.
  • a plug-in device usually, either one of these said types operates in combination with a fragrance refill cartridge.
  • the refill cartridge may be gel-based in which fragrance in the gel emanates on contact with air or, aerosol based, or alternatively, the refill cartridge may be wick-based, wherein a fragranced liquid is drawn up the wick and evaporates on exposure to the air.
  • air freshener devices serve as purely functional articles. Due to their functional nature, these devices are generally not designed to be visually striking and the consumer often hides the device from public view.
  • manufacturers to make air freshener devices which are aesthetically appealing. In so doing, air fresheners are becoming ornamental articles for the home, being placed in prominent positions in a room. Air freshener devices are fixed in their outward appearance. The only availability for consumer choice is the choice of refill fragrance. However, over a period of time, the consumer often tires of the appearance of the device and simply throws the air freshener device away in order to replace it with an alternative device. This is environmentally unfriendly and costly to the consumer.
  • air freshener devices comprise a housing and a chassis.
  • Component parts for example, electrical parts, are located around various points on the housing and the chassis. Due to this arrangement, in the event of the device becoming damaged, the consumer has no alternative but to replace the entire device. Again, this is environmentally damaging and expensive for the consumer.
  • a device for dispensing a fluid for fragrancing, deodorising or sanitising air having a body for housing at least one cartridge containing a fluid to be dispensed, the body comprising a shade, a chassis having a support surface which forms a base of the device, and a plurality of component parts which are adapted to operate the device, wherein the plurality of component parts are located on the chassis of the device, and the body is adapted to receive said cartridge through an opening in the support surface.
  • all of the component parts which are necessary to operate the device are located on the chassis of the device .
  • the shade is free of such component parts and as such is simpler to manufacture. Further, due to the component parts being located on the chassis, the centre of gravity of the device is lowered and thus the device is more stable.
  • the provision of the opening in the support surface enables a consumer to insert a fragrance cartridge from underneath the device without being directly exposed to the component parts of the device.
  • At least one light source is located on the device, preferably within the shade, more preferably on the chassis inside the shade.
  • the light source is preferably aesthetically appealing to the consumer.
  • five light sources are provided and are preferably arranged in a symmetrical curved shape around the cartridge housing, preferably a circular arrangement.
  • An especially preferred arrangement is horseshoe shape around the chamber.

  • the component parts are located on the chassis and a light source is provided on the device, preferably on the chassis and preferably inside the shade.
  • the light source is visually preferably stimulating but it also may serve as a nightlight.
  • the body comprises a support surface having an opening, and the at least one cartridge is preferably received in the body through said opening.
  • the at least one light source is a light emitting diode (LED) .
  • the LED may be a single coloured LED, for example but not restricted to, red, green or blue. Alternatively, a RGB type LED is equally suitable.
  • the at least one light source is located in the chassis.
  • the at least one light source is operable to produce a modulating light effect.
  • the at least one light source is an LED having a light intensity of preferably about 500 to 10,000 milliCandelas (mcd) , preferably about 3000 to 5000mcd, most preferably about 3900mcd. Such LEDs produce sufficient light to create the desired effect but at the same time require little electrical energy to work.

  • the device incorporates a means for the consumer to adjust the intensity of the at least one light source.
  • the device incorporates means whereby the brightness of the at least one light source is directly related to the intensity of fragrance dissemination.
  • the component parts which are preferably electrically operated, are adapted to operate only when the at least one shade is fitted to the chassis.
  • the component parts are adapted to operate only when a fragrance cartridge is located in the device.
  • a magnetic reed switch is employed to ensure that the component parts only operate when either or both of an at least one shade is fitted to the chassis or a fragrance cartridge is located in the device. Other means of achieving this are also possible.
  • the device is configured to operate as a fragrance dispenser when the shade is fitted to the chassis.
  • the device may only operate when the cartridge is present in the device.
  • Such an arrangement ensures that the power supply to the device is not drained, and it further serves as a guiding means to help guide the consumer to fit the shade of cartridge into the device properly. For example, misalignment of the shade of cartridge will, in this configuration, prevent the device from being operational .
  • the at least one light source when a light source is present in the device, the at least one light source is adapted to operate when the at least one shade is fitted to the chassis.
  • the at least one light source is adapted to operate when a fragrance cartridge is located in the device.
  • the light source preferably only operates when the shade is fitted to the device, or a cartridge is located in the device. This is achieved by the cartridge causing an electrical circuit to close. Closure of the electrical circuit causes power to be supplied to the light source. For example, a part of the cartridge may push against a part of the device, which results in the circuit being closed. Alternatively, a magnetic reed switch as hereinbefore mentioned may be i used.
  • the light source preferably operates only when fluid is present in the cartridge.
  • the container is preferably adapted such that when the fluid in the fragrance container reaches a minimum level, a minimum level indicator triggers the circuit to be broken.
  • the minimum level indicator may comprise a light sensor on the device which operates to monitor the level of fluid in the cartridge, preferably by detecting changes in light transmitted through the cartridge due to the presence or non-presence of fluid in the cartridge.
  • the cartridge is manufactured from transparent material, preferably, glass or a suitable material which allows light to pass through.
  • the light source When the minimum level is reached, the light source preferably operates to flash on/off for a set period of time. This would serve to warn the consumer that the refill cartridge should be replaced imminently.

  • the consumer is able to interchange the shades to suit his mood or the decor in a room. Thus the consumer is given an increased flexibility with the look of the device.
  • the shades are of the same colour, the consumer is provided with a "spare" shade.
  • the shade may be chosen to match a particular fragrance to be used in the device. For example, an orange shade may ⁇ be paired with a citrus fragrance cartridge. Such matching enhances the effect created by the device.

  • One possible method of fragrance recognition could include the use of a magnetic reed switch. Each fragrance variety would have the magnet in a different location around the neck of the refill bottle. When inserted into the device the magnet on the refill would trigger the reed switch adjacent to the magnet. Depending on which reed switch in the device was activated, a specific colour of LED would be illuminated.

  • the total cycle time is 10s. Speed control options allow the consumer to set the cycle time, for example, to 2.5s, 5s, 10s, 20s or 40s or any time in between.
  • a candle mode uses yellow LEDs or the yellow colour achieved by RGB LEDs.
  • one or more LEDs is held in a static yellow mode while one or more other LEDs is switched on/off in a yellow mode to produce a flicker effect.
  • the on/off cycle is typically fast, with on and off being of preferably equal duration and preferably 5 cycles being achieved per second.
  • the pulse speed can be varied by the consumer.
  • the mode of operation of the LEDs 74 can produce a flickering effect reminiscent of a candle flickering. Further, an effect may be produced over a programmed time period which may coincide with a change in the intensity of the fragrance. For example, a red candle may coincide with a strong intensity of fragrance and the fragrance decreases in intensity as the LED changes to an orange colour. The effect can be enhanced by the use of the filter element working in co-operation with the LEDs.

  • a circuit breaker may comprise a magnetic reed switch.
  • a recognition system is provided on the device 2.
  • the recognition system comprises electronic identification means which can be located on the device 2, on each shade 8, and on a cartridge to be used in the device.
  • the identification means detects a preferred match, for example, a particular shade with a particular fragrance cartridge.
  • the consumer chooses a preferred shade 8 and fixes said shade 8 to the chassis 10.
  • the consumer can make his choice according to the recognition system as hereinbefore mentioned.
  • the cartridge 36 is then inserted into the opening 34 in the chamber 26 of the air fragrancing device 2.
  • the vent 32 provides an easily- accessible thumb hole for inserting and removing the cartridge 36.
  • the contours of the chamber wall 38 act to guide the cartridge 36 towards an operative position in which the wick 40 passes through the chamber 26 and into the portal 55 of the heat source 54; the end of the wick ⁇ 40 is co-linear with an end of the heat source 54.
  • the shoulders of the cartridge 36 abut against the fins 46 of the chamber 26.
  • the neck of the cartridge 36 is pushed against the arms 42 which resiliently deform to receive said cartridge 36. In this position, the air fragrancing device 2 is releasably held in the operative position.

Together, the portion 37 of the cartridge 36 and the support surface 31 form the base 6 of the device. Due to this configuration, a level base 6 of the device 2 is achieved. The user is able to place the device 2 down on a surface and the device remains in a steady configuration. In this position, a section of the cartridge 36 remains visible to the consumer due to the vent 32 in the skirt 24 of the chassis 10. This allows the consumer to monitor the level of liquid remaining in the cartridge 36, particularly when nearing the end of life of the cartridge 36.

  • the LEDs 74 in the air fragrancing device 2 can be switched on by pushing the operating button 72 into an operative position.
  • the operating button 72 can operate either or both the LEDs 74 or heat source 54.
  • the air fragrancing device 2 is visually striking to a consumer while simultaneously operating as a fragrance dispenser.
  • the light effect is not diminished by unsightly shadowing of internal parts of the device because of the arrangement of the collar 53 and flange 56 which co-operate to minimise such an effect.
  • the smoothed internal surfaces of the device 2 further ensure unwanted shadowing is minimised. Particularly, there are substantially no sharp corners on snap fits or screw points on the internal surface.
  • the ability to interchange shades 8 of the device 2 provides the consumer with a choice of external appearance of the device 2. Further, because a particular shade can be fitted with the identification means, the shade can be matched to a specific cartridge fragrance.
  • the recognition means can be mechanical, for example, using co-operating mechanical parts on the shade and cartridge. The recognition system can also cause the operation of a particular mode of LEDs.
  • the vent 32 provides a viewing window for the consumer.
  • the appeal of this feature is enhanced when the or each cartridge 36,136 is manufactured from transparent material and the fluid contained therein is coloured. When a plurality of cartridges is provided, each may contain a different coloured fluid. Also, due to the transparent nature of the or each cartridge, the consumer is given a visual indication of how full the cartridge is and when to replace it.
  • the or each cartridge is manufactured from glass.
  • Glass is a robust material which can be blown thick enough to withstand impact .
  • the manufacture of glass does not generally create sharp edges, which may sometimes result from injection moulding of plastics.
  • glass is compatible with the combination of fragrance and heat .
  • the configuration of a portion of the cartridge forming a part of the base of the device, together with the support surface of the chamber, requires less material to make the device. Therefore, the cost of producing the device is less than that compared to a device which incorporates a complete and integrally moulded base.
  • the chamber may be manufactured from plastics material. Particularly suitable plastics materials are those which are opaque in nature, for example polypropylene. In so doing, the opaque areas aid in hiding internal component parts.
  • the invention is not limited to the use of a fragrance but is equally suited to use with liquids for pest control, pharmaceutical preparations which can be vaporised, for example, formulations to ease congestion.
  • the light source is preferably a UV light, particularly a UV germicidal light.
  • the device is shown connected to a mains power lead, • it is envisaged that the device make comprise a docking station and rechargeable batteries. Such an arrangement allows the consumer to move the device around the home and outside, for example to the garden. When used in the garden, the device is preferably adapted for pest control .
