Definitions

  • the present invention elates to a plug-in fragrancer and particularly to a fragrancer which delivers more than one fragrance to the ambient atmosphere.
  • Plug-in fragrancers are well known and typically comprise a liquid fragrance which is held in a container.
  • a wick extends out of the container into close proximity with a heating element which is powered from mains " electricity. Heat from the heating element causes accelerated evaporation of the fragrance from the wick to disperse the fragrance to the ambient atmosphere.
  • One such device is seen in EP-A-451 331.
  • AU2005 101001 describes a triple fragrance system in which, in its commercial implementation, three ceramic heaters are embedded in respective cavities of a plastics moulding which has apertures or chimneys in which the wicks are received.
  • the cavities are connected by bridges to from a unitary heating block.
  • This arrangement enables heat to be focussed at individual wicks but there is still a problem with heat transfer via the moulding bridges.
  • a plug-in fragrancer having at least three containers for fragrances, a wick extending from each container, wherein a heating device for causing evaporation of fragrance from the wicks comprises three heaters which are mounted spaced apart to provide a gap between the heaters.
  • the gap may be filled with a thermal insulator, preferably air.
  • the heaters may be mounted on a common circuit board to facilitate manufacture and assembly of the device.
  • the heaters may be of the ceramic type, preferably with an aperture through the heater body.
  • each heater may be formed by a resistive heating element embedded in a thermally conductive plastics housing.
  • a control circuit may be provided to switch on each heater in turn. Preferably there is a time gap between switching off one heater and turning on another heater. A heater will maintain its temperature for some time and so it is desirable to let the heater cool to a temperature at which little fragrance is emitted, before switching on the next heater. This avoids substantial overlap of the release of two fragrances. In some situations, of course, it maybe desirable to have overlap.
  • the duty cycle of a heater may be varied to provide a greater or lesser amount of heat or higher or lower temperature, and so release higher or lower amounts of fragrance during the 'on' period of a heater and its subsequent cooling down period.
  • Each heater may be 'on' for a period of from 10 to 30 minutes and there may be a gap of from 15 to 35 minutes before another heater is switched on.
  • a heater may be on for a period of 15 to 25 minutes, preferably about 20 minutes.
  • a time gap of from 20 to 30 minutes may be provided before the next heater is switched on, preferably about 25 minutes.
  • the control circuit may be adapted to switch randomly between the heaters or to cycle through them sequentially.
  • the containers when assembled together may provide a generally semicircular outline in plan view.
  • the containers are of identical shape.
  • Three containers may be provided.
  • the containers are held together at one end to provide a refill unit, so that the multiple containers can be removed from the device and replaced as a single unit.
  • a supporting bracket which engages the lower end of one container and clips into a housing.
  • Figure 1 is a perspective view of a plug-in fragrancer in accordance with the invention.
  • Figure Ia is a perspective view of the fragrancer of Figure 1 with a front cover removed;
  • Figure 2 is an exploded view of the fragrancer of Figure 1;
  • Figure 3 is a cross-section on line III-III of Figure 1;
  • Figure 4 shows a refill unit for the fragrancer of Figure 1
  • Figures 5a and 5b show a fragrance container for the fragrancer of Figure 1 ;
  • Figures 6a and 6b show front and rear perspective views of a refill unit
  • Figures 7a to 7d show a method of insertion of a refill unit.
  • a plug-in fragrancer 2 in accordance with the invention comprise a top cover 4 having three apertures 6 through which fragrance is released.
  • Three transparent containers or bottles 8a, 8b, 8c having a generally truncated sector shaped cross-section are held together to provide an arcuate cylindrical outer surface 66.
  • An outer cover 10 covers the container outlets and wicks and associated heaters as will be described hereinafter.
  • An electrical switch 12 controls the rate of fragrance release.
  • each container 8a, 8b, 8c has a neckl4 in which a wick 16 is held by a plastic collar 18.
  • a cap not shown, is screwed onto the threaded neck 14, covering the wick 16, to seal the container and is removed prior to the insertion of the container into the fragrancer.
  • a collar 20 is a snap fit onto the upper ends of the containers to hold the containers together so that they can be handled as single unit.
  • a bracket or tray 22 is a snap fit onto a base 24 of the central container 8b only.
  • the wick 16 extends down into fragrance 17 in the container and fragrance is ducted up to the upper wick portion 16a.
  • a printed circuit board 26 carries electronic control circuitry (not illustrated), three heaters 28, switch 12 and LEDs 30.
  • the PCB 26 is held between a back cover 32 and a chassis 34.
  • the PCB is electrically connected with two plug pins (not shown) which extend through apertures 35 in the back cover 32.
  • the safety or earth pin 33 of a UK style electrical plug is shown moulded integrally with the back cover 32.
  • Heaters 28 may take various forms as known in the art but we presently prefer a resistive heater which is embedded or potted in a ceramic holder or a resistive heater embedded or housed in a thermally conductive plastics such as polybutylene terepthalate.
  • the heater 28 has a body 38 which has a through aperture 40 which receives the upper end 16a of the wick 16. As seen in Figure Ia, the heaters 28 are separated, that is spaced apart on the PCB, with a thermally insulating air gap 29 between them.
  • the heaters 28 are mounted on the PCB by electrically conductive wires 36.
  • the heaters are positioned above a plate 78 on the chassis 34.
  • Plate 78 has apertures 80 which are aligned with the apertures 40 in the heater bodies 38 (refer to Figure 3).
  • the LEDs 30 are positioned near a thin wall region 42 of the back cover (they are not shown in Figure Ia).
  • An LED is associated with a respective heater 28.
  • the LED may be illuminated when the heater is 'on', i.e. when voltage is being applied to the heater, or during the full cycle of the heater, that is the 'on' period and the subsequent cool down period before the next heater is switched on.
  • the illuminated LED 30 will be seen through the wall portion 42.
  • a collar 38a on the heater body 38 extends up to be level with the upper surface of the cover 4, to provide a heated path for the fragrance as it leaves the plug-in fragrancer unit 2.
  • a refill unit 50 (with container caps removed) comprises three containers 8a, 8b, 8c held together by collar 20 which is snap fit onto the upper ends of the containers.
  • Tray 22 is a snap fit onto the bottom end of the centre container 8b only and has a tongue 56 which engages with a recess or detent 58 in the chassis 34 to hold the refill unit in place.
  • a skirt 22a passes around the front of the side containers 8a, 8c for aesthetic effect.
  • FIGS. 5a and 5b show a container 8a, 8b, 8c which is moulded of glass, for example.
  • the containers 8a, 8b, 8c are identical, but typically will be filled with different fragrances.
  • the container has bottom portion 24 which has a groove 58 to receive a nibs 59 on radial ribs 60 and a back rib 61 of a central portion of tray 22 (see Figure 2) so that the tray 22 is a snap fit onto the central container 8b.
  • the container upper portions 62 also have recesses 64 formed therein to receive nibs formed on the collar 20 which serves to secure the three containers 8a, 8b, 8c together.
  • the containers have an arcuate outer wall 68, side walls 70 which are formed on a radius of the arcuate outer wall 68, and a flat rear wall 72.
  • the collar 20 and or tray 22 may be glued in place.
  • the container 8a, 8b, 8c may be glued together.
  • the collar 20 and the rear walls 72 of the three containers 8a, 8b, 8c form a recess 90 and the tongue 56 extends upwards and carries teeth 72 on a flexible portion 74 to engage the detent 58 in the chassis 34.
  • the cover 10 and chassis form a cavity 80.
  • a saddle 82 is provided on the chassis 34 and corresponds to the recess 70.
  • the refill is offered up to the chassis, below the cavity 80, the saddle 82 facing the recess 90 at the level of the collar 20 ( Figure 7b).
  • the unit is then slid upwards (Figure 7c), the tongue 56 sliding in a recess 96 in the chassis 34, until the teeth 92 engage in the detent 58 to lock the refill in place ( Figure 7d).
  • the refill can be removed by pulling firmly downwards so that teeth 92 ride out of the detent 58.
  • a fragrancer is typically provided with a refill unit 50 on the initial sale, and so strictly speaking it is not a refill unit at that time, but subsequent units, refill units, are purchased to replace the used unit 50.
