Abstract

A filtered exhaust conduit is provided. The conduit includes an intake end, an exit end, a curved section, a vent, and a filter device. The intake end is connectable to a blower unit, while the exit end is connectable to a debris collector container. The curved section extends between and joins the intake end and the exit end. The vent is between the intake end and the exit end and is positioned through a lower inner wall of the filtered exhaust conduit. The filter device is removably secured over the vent to form a substantially air tight fit on the vent. An organic debris collection device having the filtered exhaust conduit is also provided.

Claims

1. A filtered exhaust conduit comprising:

an intake end connectable to a blower unit;

an exit end connectable to a debris collector container;

a curved section extending between and joining said intake end and said exit end;

a vent between said intake end and said exit end, said vent being positioned through a lower inner wall of the filtered exhaust conduit; and

a filter device removably secured over said vent to form a substantially air tight fit on said vent.

2. The filtered exhaust conduit of claim 1, wherein said filter device comprises a filter bag.

3. The filtered exhaust conduit of claim 2, wherein said filter bag comprises a neck area for maintaining said substantially airtight fit.

4. The filtered exhaust conduit of claim 1, wherein said filter device comprises a cyclone separator.

5. The filtered exhaust conduit of claim 4, wherein said cyclone separator comprises a collection container for collecting separated particles and an outlet pipe for venting cleaned air.

6. The filtered exhaust conduit of claim 5, wherein said collection container is removably secured to said cyclone separator.

7. The filtered exhaust conduit of claim 5, wherein said collection container is made of a transparent or translucent material.

8. The filtered exhaust conduit of claim 1, wherein said vent comprises a pair of oppositely directed exhaust vents.

9. The filtered exhaust conduit of claim 8, wherein said filter device comprises a single filter bag having a pair of neck areas, each of said pair of necl areas being removably secured over a respective one of said pair of exhaust vents.

10. The filtered exhaust conduit of claim 8, wherein said filter device comprises a pair of filter bags, each of said pair of filter bags being removably secured over a respective one of said pair of exhaust vents.

11. The filtered exhaust conduit of claim 10, wherein said filter device further comprises one or more elastic members securing said pair of filter bags to one another.

12. The filtered exhaust conduit of claim 8, wherein said filter device comprises a cyclone separator positioned at each of said pair of exhaust vents.

13. The filtered exhaust conduit of claim 12, wherein said cyclone separators each comprise a collection container removably secured to said cyclone separator.

14. The filtered exhaust conduit of claim 13, wherein, said collection container is made of a transparent or translucent material.

15. The filtered exhaust conduit of claim 1, wherein said curved section has a sector angle of about 75 degrees.

16. An organic debris collection device comprising:

a blower unit;

a debris collector container;

an exhaust conduit having an intake end connected to said blower unit and an exit end connected to said debris collector container;

a vent between said intake end and said exit end, said vent being positioned through a lower inner wall of said exhaust conduit; and

a filter device removably secured over said vent to form a substantially air tight fit on said vent.

17. The organic debris collection device of claim 16, wherein said collector container is selected from the group consisting of a closed rigid container, a closed soft container, a vented rigid container, a vented soft container, and any combinations thereof.

18. The organic debris collection device of claim 16, wherein said exhaust conduit comprises a curved section having a sector angle of between about 40 to about 90 degrees.

19. The organic debris collection device of claim 16, wherein said vent comprises a pair of oppositely directed exhaust vents, said filter device comprising a pair of filter bags, each of said pair of filter bags being removably secured over a respective one of said pair of exhaust vents.

20. The organic debris collection device of claim 19, wherein said filter device further comprises one or more elastic members securing said pair of filter bags to one another.

21. The organic debris collection device of claim 16, wherein said vent comprises a pair of oppositely directed exhaust vents, said filter device comprising a cyclone separator positioned at each of said pair of exhaust vents.

22. The organic debris collection device of claim 21, wherein said cyclone separator comprises a collection container for collecting separated particles and an outlet pipe for venting cleaned air, said collection container being removably secured to said cyclone separator.
