Abstract

An aroma diffuser assembly is provided with an electrical wire heating element for effecting the release of an aroma from a contained aroma producing material. Power is supplied to the heating element by a power supply assembly which has a first portion for electrical connection to an external power source and a second portion for supplying power from the external power source to other than the heating element. The power supply assembly is rotational within the aroma diffuser assembly to accommodate both vertical and horizontal orientations of a conventional household outlet as a source of power.

Claims

1. An aroma diffuser assembly comprising a housing providing a cavity for receiving aroma producing material, heating means within said housing for effecting the release of an aroma from the aroma producing material, and power supply means for supplying power to said heating means, said power supply means having a first portion for electrical connection to an external power source and a second portion having connecting means for supplying power from said external power source through said housing to an external power consuming apparatus when engaged with said connecting means, said power being supplied to said connecting means independent of the supplying of said power to said heating means.

2. The assembly of claim 1, further including aroma producing material received within said cavity.

3. The assembly of claim 1, wherein said housing includes an openable top for providing access to said cavity.

4. The assembly of claim 1, wherein said heating means is arranged underlying said cavity.

5. The assembly of claim 4, wherein said heating means comprises a pair of spaced-apart members providing a vertical opening therebetween, a heating element disposed between said members, and a temperature regulator arranged within said vertical opening above said heating element.

6. The assembly of claim 1, wherein said housing includes a plurality of inwardly projecting ribs for supporting the aroma producing material.

7. The assembly of claim 1, wherein said power supply means is rotatable between a first position and a second position to maintain said housing in a preselected orientation.

8. The assembly of claim 7, wherein said first position and said second position are approximately 180°

apart.

9. The assembly of claim 7, wherein said housing includes stop means for engaging a portion of said power supply means to prevent the further rotation thereof when arranged in said first position or said second position.

10. The assembly of claim 7, wherein said power supply means is shiftable with respect to said housing between a first location whereby said power supply means is prevented from rotation and a second location, whereby said power supply means is rotatable about its axis.

11. The assembly of claim 10, wherein said first portion of said power supply means is located within said housing and said second portion of said power supply means is located outside said housing when said power supply means is arranged in said second location.

12. The assembly of claim 11, wherein said first portion of said power supply means comprises a circular member and said second portion of said power supply means comprises a rectangular member, said circular member received within a corresponding circular opening within said housing and said rectangular member received within a corresponding rectangular opening within said housing when said power supply means is arranged within said first location.

13. The assembly of claim 12, wherein said rectangular opening is formed of a portion of said housing having means for preventing the inward movement of said rectangular member.

14. The assembly of claim 12, wherein said circular opening is formed of a portion of said housing having means for limiting the inward movement of said circular member.

15. The assembly of claim 14, wherein a portion of said housing forming said circular opening includes stop means for engaging a portion of said power supply means to limit the extent of rotation of said power supply means.

16. The assembly of claim 10, wherein said housing includes positioning means for positioning said power supply means in said first location.

17. The assembly of claim 16, wherein said positioning means includes plurality of projecting members engaging said first portion of said power supply means.

18. The assembly of claim 17, wherein said first portion of said power supply means is shiftable to said second location upon application of a sufficient force to displace said first portion from one side of said projecting members to the other side thereof inwardly of said housing, whereby said power supply means may be rotated about its axis.

19. An aroma diffuser assembly comprising a housing providing a cavity for receiving aroma producing material, heating means within said housing for effecting the release of aroma from the aroma producing material, and power supply means arranged within an opening of said housing for supplying power to said heating means, said power supply means shiftable between a first location releasably secured within said housing at a selected orientation and a second location within said housing permitting rotation of said power supply means between a plurality of orientations, and a projecting member extending from said housing and into said opening, said projecting member maintaining said power supply means at said first location and said second location, said power supply means shiftable between said first location and said second location upon application of a sufficient force to displace said power supply means from one side of said projecting member to the other side thereof.

20. The assembly of claim 19, wherein said heating means comprises a pair of spaced-apart members providing a vertical opening therebetween, a heating element disposed between said members, and a temperature regulator arranged within said vertical opening above said heating element.

21. The assembly of claim 19, further including aroma producing material received within said cavity.

22. The assembly of claim 19, wherein said power supply means is rotatable between a first position and a second position to maintain said housing in a preselected orientation.

23. The assembly of claim 22, wherein said housing includes stop means for engaging a portion of said power supply means to prevent the further rotation thereof when arranged in said first position or said second position.

24. The assembly of claim 19, wherein said power supply means includes a circular member and a rectangular member, said circular member received within a corresponding circular opening within said housing and said rectangular member received within a corresponding rectangular opening power supply means when in said first location.

25. An aroma diffuser assembly comprising a housing providing a cavity for receiving aroma producing material, heating means within said housing for effecting the release of aroma from the aroma producing material, and power supply means arranged within an opening of said housing for supplying power to said heating means, said power supply means shiftable between a first location releasably secured within said housing at a first orientation and a second location permitting rotation of said power supply means to a second orientation, said power supply means being releasably secured within said housing at said second orientation upon shifting said power supply means to said first location from said second location.

26. The assembly of claim 25, wherein said heating means comprises a pair of spaced-apart members providing a vertical opening therebetween, a heating element disposed between said members, and a temperature regulator arranged within said vertical opening above said heating element.

27. The assembly of claim 25, further including aroma producing material received within said cavity.

28. The assembly of claim 25, wherein said housing includes stop means for engaging a portion of said power supply means to prevent the further rotation thereof when arranged in said first orientation or said second orientation.

29. The assembly of claim 25, wherein said power supply means includes a circular member and a rectangular member, said circular member received within a corresponding circular opening within said housing and said rectangular member received within a corresponding rectangular opening within said housing, thereby preventing rotation of said power supply means when in said first location.
