Abstract

Embodiments are directed to a vacuum cleaner and removably attachable filter. The filter is configured to separate debris from a flow of fluid drawn through the suction inlet. The filter includes a housing forming a first volume and a filter media forming a second inner volume. The filter media is coupled to the housing such that the first and second inner volumes together at least partially define a collection container configured to store debris separated by the filter media from the flow of fluid. The filter further includes an inlet opening that extends through the housing to provide fluid communication into the collection container such that the flow of fluid with the debris can flow into the collection container such that the flow of fluid with the debris can flow into the collection container and a relatively clean flow of fluid exits through the filter media.

First claim

What is claimed is:

1. A vacuum cleaner comprising:
a suction inlet and a suction source configured to draw debris through the suction inlet;
a conduit in fluid communication with the suction inlet, the conduit including a first magnetic member;
a filter having an inner volume configured to collect debris from the conduit, the filter having a valve releasably connected to a filter inlet opening, the valve including a second magnetic member, the first and second magnetic members being attracted to one another; and
the filter being moveable from a first position to a second position, wherein the filter in the first position is in fluid communication with the conduit with the valve being disengaged from and opening the filter inlet opening to collect the debris, and wherein the filter in the second position is disconnected from the conduit with the valve closing the filter inlet opening.

2. The vacuum cleaner of claim 1 , wherein movement of the filter to the first position disconnects the valve from the filter inlet opening and magnetically couples the valve to the conduit.

3. The vacuum cleaner of claim 2 , wherein the valve includes flexible fingers on an outer periphery thereof to engage the inlet opening, and the valve includes a pocket that receives the conduit.

4. The vacuum cleaner of claim 3 , wherein the flexible fingers are configured to couple the valve to the conduit.

5. The vacuum cleaner of claim 1 , wherein the first magnetic member is a magnet and the second magnetic member includes a material attracted by a magnet.

6. The vacuum cleaner of claim 1 , wherein the second magnetic member is a material forming at least a portion of the valve.

7. The vacuum cleaner of claim 1 , wherein movement of the filter from the first position to the second position connects the valve to the filter inlet opening and releases the valve from the conduit.

8. The vacuum cleaner of claim 7 , wherein the valve is coupled to the conduit by magnetic force between the conduit and the valve retaining the valve to the conduit until the valve connects to the filter inlet opening during movement of the filter to the second position.

9. The vacuum cleaner of claim 8 , wherein the valve remains coupled to the conduit until a force pressing the valve away from the conduit exceeds a pre-determined threshold.

10. A filter configured to separate debris from a flow of fluid in a vacuum cleaner having a conduit for coupling to the filter, the conduit including a conduit magnetic member, the filter comprising:
a housing;
a filter media coupled to the housing to form a collection container having an inner volume configured to store debris separated by the filter media from the flow of fluid;
an inlet opening extending through the housing; and
a valve releasably connected to the inlet opening, the valve movable between an opened position and a closed position, movement of the valve to the open position disconnects the valve from the inlet opening and the housing, the valve including a valve magnetic member, the valve magnetic member and conduit magnetic member being attracted to one another;
wherein the inlet opening provides fluid communication into the collection container when the valve is in the opened position such that the flow of fluid with the debris can flow into the collection container and a relatively clean flow of fluid exits through the filter media.

11. The filter of claim 10 , wherein the valve includes flexible fingers on an outer periphery thereof to engage the inlet opening, and the valve includes a pocket that receives the conduit.

12. The filter of claim 10 , wherein the conduit magnetic member is a magnet and the valve magnetic member includes a material attracted by a magnet.

13. The filter of claim 10 , wherein the valve magnetic member is a material forming at least a portion of the valve.

14. The filter of claim 10 , further comprising a seal between the valve and the housing at the inlet opening.
