Abstract

A docking station for a dust collection box comprising: a housing; a socket formed by the housing configured to receive a dust collection box of a dust extractor; first and second apertures formed through a wall of the housing which aligns with air outlet and inlet apertures of a dust collection box when the dust collection box is mounted within the socket; a connector connectable to a vacuum source; and a dust channel mounted inside of the housing, which provides a passageway between the second aperture and the connector. The docking station may further include an air vent formed through a wall of the housing to allow air surrounding the housing to enter a cavity formed inside of the housing, where the first aperture is connected to the cavity in the housing to allow air in the cavity to exit the housing through the first aperture.

First claim

The invention claimed is:

1. A docking station for a dust collection box comprising:
a housing;
a socket formed by the housing configured to receive a dust collection box of a dust extractor;
a first aperture formed through a wall of the housing which aligns with an air outlet aperture of a dust collection box when the dust collection box is mounted within the socket;
a second aperture formed through a wall of the housing which aligns with an air inlet aperture of a dust collection box when the dust collection box is mounted within the socket;
a connector connectable to a vacuum source; and
a dust channel, formed inside of the housing, which provides a passageway between the second aperture and the connector.

2. A docking station for a dust collection box according to claim 1 , further comprising:
at least one air vent formed through a wall of the housing to allow air surrounding the housing to enter a cavity formed inside of the housing,
wherein the first aperture is connected to the cavity in the housing to allow air in the cavity to exit the housing through the first aperture.

3. A docking station according to claim 1 , wherein the first aperture is located in a wall which forms part of the socket.

4. A docking station according to claim 1 , wherein the second aperture is located in a wall which forms part of the socket.

5. A docking station according to claim 1 , wherein the first and second apertures are located in the same wall.

6. A docking station according to claim 2 , wherein air passing through the cavity is prevented from interacting with air passing through the dust channel.

7. A docking station according to claim 1 , wherein the connector is a tube which extends away from the housing.

8. A docking station according to claim 1 , wherein the connector is integrally formed with the dust channel.

9. A docking station according to claim 1 , wherein the dust channel comprises two plastic clam shells which are fastened to each other.

10. A docking station according to claim 1 , wherein the connector is a standard design of connector capable of engaging an adapter of a vacuum cleaner.

11. A docking station according to claim 1 , wherein at least one of the dust channel and/or connector are made from an anti-static material.

12. A docking station according to claim 1 , wherein the housing comprises two clam shells which are fastened to each other.

13. A docking station according to claim 12 , wherein the dust channel is mounted within the housing by a part of the dust channel being sandwiched between and held by parts of each of the two clam shells when the two clam shells are fastened to each other.

14. A docking station according to claims 13 wherein a seal surrounds the dust channel which is sandwiched between the dust channel and the parts of the two clam shells which are holding the dust channel to prevent air from passing between the dust channel and the parts of the two clam shells which are holding the dust channel.

15. A docking station according to claim 2 , further comprising internal walls within the housing which act as air guides to direct the movement of the air inside of the cavity.

16. A docking station according to claim 1 , wherein the housing is mounted on a frame.

17. A docking station according to claim 16 , wherein the frame comprises:
a rectangular metal bar which is angled towards one end to form a raised portion and a horizontal portion;
a cross bar is attached to the rectangular bar at both of its ends and which traverses it in a width wise direction between the sides of the rectangular bar across the horizontal portion; and
a rib formed along the top of the cross bar which engages with a slot formed in the underside of the housing when the frame is attached to the housing;
wherein the frame is attached to the housing by locating the rib within the slot and attaching the raised portion to the housing.

18. A docking station according to claims 17 , wherein the raised portion extends from the horizontal portion part way up the front of the housing.

19. A docking station according to claim 17 , wherein the horizontal portion of the frame extends under the full width of the housing and past the rear of the housing so that, when a dust collection box is mounted on the docking station, the horizontal portion extends beneath the dust collection box.

20. A docking station according to claim 17 , wherein, when docking station is placed on a work surface, the horizontal portion lies against the work surface to support the docking station.

21. A docking station according to claim 1 , wherein the dust channel comprises a tube which is mounted within the housing.

22. A dust collection box cleaning system comprising a docking station according to claim 1 and a dust collection box, wherein the dust collection box comprises:
a housing;
a filter mounted within the housing;
a first air inlet chamber formed within the housing;
an air inlet aperture in a wall of the housing which connects to the first air inlet chamber through which air is capable of being drawn into the first air inlet chamber when used on a dust extractor; and
an air outlet aperture formed in the wall of the housing which connects to the filter through which air is capable of being drawn through the filter by a vacuum source when mounted on a dust extractor;
wherein the first inlet chamber is connected to the filter;
wherein, when the dust collection box is mounted on the docking station, air is capable of being drawn out of the first air inlet chamber through the air inlet aperture in the wall of the housing of the dust collection box and into the second aperture formed through a wall of the housing of the docking station.

23. A dust collection box cleaning system according to claim 22 , wherein there is further provided a first aperture formed through a wall of the housing of the docking station which aligns with an air outlet aperture of a dust collection box when the dust collection box is mounted within the socket;
wherein at least one air vent is formed through a wall of the housing to allow air surrounding the housing to enter a cavity formed inside of the housing;
wherein the first aperture is connected to the cavity in the housing to allow air in the cavity to exit the housing through the first aperture;
wherein the first aperture is connected to the cavity in the housing to allow air in the cavity to exit the housing through the first aperture; and
wherein, when the dust collection box is mounted on the docking station, air is capable of being blown through the filter via the air outlet aperture formed in the wall of the housing of the dust collection box from the first aperture formed through the wall of the housing of the docking station.

24. A dust collection box cleaning system as claimed in claim 22 , wherein there is further provided a second air outlet chamber formed within the housing of the dust collection box;
wherein the air outlet aperture formed in the wall of the housing connects to the air outlet chamber through which air is capable of being drawn out of the air outlet chamber by a vacuum source when mounted on a dust extractor;
wherein the first inlet chamber is connected to the second air outlet chamber via the filter;
wherein there is further provided a first aperture formed through a wall of the housing of the docking station which aligns with the air outlet aperture of a dust collection box whe
