Abstract

A vacuum cleaner including a suction inlet, a conduit in fluid communication with the suction inlet, a filter having a valve releasably connected to a filter inlet, the filter configured to collect debris drawn through the suction inlet. The vacuum cleaner further comprising a release mechanism moveable from a first position to a second position. In the first position, the filter is in fluid communication with the conduit to collect debris with the valve being open, and in the second position, the filter is disconnected from the conduit with the valve being closed. Movement of the release mechanism between the first and second positions closes the valve.

First claim

What is claimed is:

1. A vacuum cleaner comprising:
a suction inlet;
a conduit in fluid communication with the suction inlet;
a filter having a valve releasably connected to a filter inlet, the filter configured to collect debris drawn through the suction inlet; and
a release mechanism moveable from a first position to a second position, wherein in the first position, the filter is in fluid communication with the conduit to collect debris with the valve being open, and in the second position, the filter is disconnected from the conduit with the valve being closed,
wherein the valve is coupled to the conduit for movement with the conduit to move the valve to the open and closed positions, and
wherein movement of the release mechanism from the first position to the second position closes the valve and ejects the filter from the vacuum cleaner.

2. The vacuum cleaner of claim 1 , wherein a user can eject the filter without touching the filter.

3. The vacuum cleaner of claim 1 , wherein the conduit extends into the filter when the release mechanism is in the first position.

4. The vacuum cleaner of claim 1 , wherein the release mechanism is operable such that a user can dispose of the filter without touching the filter.

5. The vacuum cleaner of claim 1 , wherein the valve includes an engagement member to engage at least one of the upper housing and the inlet, and a receiver that couples the valve to the conduit.

6. The vacuum cleaner of claim 5 , wherein the engagement member is provided on the outer periphery to engage the inlet, and the receiver is a pocket that receives and couples to the conduit.

7. The vacuum cleaner of claim 1 , further comprising a seal between the valve and the inlet.

8. The vacuum cleaner of claim 7 , where the seal is an o-ring.

9. A vacuum cleaner comprising:
a suction inlet;
a conduit in fluid communication with the suction inlet;
a filter having a valve releasably connected to a filter inlet, the filter configured to collect debris drawn through the suction inlet; and
a release mechanism moveable from a first position to a second position, wherein in the first position, the filter is in fluid communication with the conduit to collect debris with the valve being open, and in the second position, the filter is disconnected from the conduit with the valve being closed,
wherein the valve is coupled to the conduit for movement with the conduit to move the valve to the open and closed positions, and
wherein movement of the release mechanism between the first and second positions closes the valve,
wherein the filter includes
an upper housing configured to be supported by the vacuum cleaner;
a lower housing coupled to the upper housing;
a filter media coupled to the upper housing, the filter media and the upper housing at least partially define a chamber configured to collect debris; and
wherein the valve is coupled to the upper housing and movable between the open position where debris is permitted to enter the chamber and the closed position where debris is inhibited from entering and exiting the chamber.

10. The vacuum cleaner of claim 9 , wherein the lower housing is a film.

11. A vacuum cleaner comprising:
a suction inlet;
a conduit in fluid communication with the suction inlet;
a filter having a valve releasably connected to a filter inlet, the filter configured to collect debris drawn through the suction inlet; and
a release mechanism moveable from a first position to a second position, wherein in the first position, the filter is in fluid communication with the conduit to collect debris with the valve being open, and in the second position, the filter is disconnected from the conduit with the valve being closed,
wherein the valve is coupled to the conduit for movement with the conduit to move the valve to the open and closed positions, and
wherein movement of the release mechanism between the first and second positions closes the valve,
wherein the filter includes
an upper housing configured to be supported by the vacuum cleaner; and
a filter media coupled to the upper housing, the filter media and the upper housing at least partially define a chamber configured to collect debris, and the filter media is moveable between a collapsed position and an expanded position,
wherein at least a portion of the filter media is encased by the upper housing when the filter media is in the collapsed position, and the filter media extends away from the upper housing when the filter media is in the expanded position.

12. The vacuum cleaner of claim 11 further comprising a lower housing, wherein the filter media is encased by the upper housing and the lower housing when the filter media is in the collapsed position.

13. The vacuum cleaner of claim 12 , wherein the lower housing is movable relative to the upper housing.

14. The vacuum cleaner of claim 12 , wherein the lower housing is a film.

15. The vacuum cleaner of claim 11 , wherein the filter media includes a nonwoven, HEPA filter material.

16. The vacuum cleaner of claim 11 , wherein the valve is coupled to the upper housing and movable between the open position where debris is permitted to enter the filter and the closed position where debris is inhibited from entering and exiting the filter.

17. The vacuum cleaner of claim 16 , wherein the upper housing includes an inlet, and wherein the valve is received within the inlet when the valve is in the closed position.

18. A vacuum cleaner comprising:
a suction inlet;
a conduit in fluid communication with the suction inlet;
a filter having a valve releasably connected to a filter inlet, the filter configured to collect debris drawn through the suction inlet; and
a release mechanism moveable from a first position to a second position, wherein in the first position, the filter is in fluid communication with the conduit to collect debris with the valve being open, and in the second position, the filter is disconnected from the conduit with the valve being closed,
wherein the valve is coupled to the conduit for movement with the conduit to move the valve to the open and closed positions, and
wherein movement of the release mechanism between the first and second positions closes the valve,
wherein the filter includes
an upper housing configured to be supported by the vacuum cleaner; and
a filter media coupled to the upper housing, the filter media and the upper housing at least partially define a chamber configured to collect debris, and the filter media is moveable between a collapsed position and an expanded position,
wherein at least a portion of the filter media is encased by the upper housing when the filter media is in the collapsed position.

19. The vacuum cleaner of claim 18 , further comprising a lower housing, wherein the filter media is encased by the upper housing and lower housing when the filter media is in the collapsed position.

20. The vacuum cleaner of claim 18 , wherein an end of the filter media extends away from the upper housing a desired length forming an overlapping filter media section.
