Abstract

A handheld vacuum cleaner including a suction inlet, a main body, a handle defined by a portion of the main body, a motor disposed within the main body operating a suction source, and a filter coupled to the main body. 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 handheld vacuum cleaner comprising:
a suction inlet;
a main body and a handle defined by a portion of the main body;
a motor disposed within the main body operating a suction source; and
a filter coupled to the main body, the filter configured to separate debris from a flow of fluid drawn through the suction inlet, the filter including
a housing forming a first volume;
a filter media forming a second inner volume, the filter media 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;
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 and a relatively clean flow of fluid exits through the filter media.

2. The handheld vacuum cleaner of claim 1 , wherein the filter is releasable from the main body without a user touching the filter.

3. The handheld vacuum cleaner of claim 1 , further comprising a conduit in fluid communication with the suction inlet, wherein the conduit extends into the collection container coupling the filter to the conduit.

4. The handheld vacuum cleaner of claim 3 , wherein the filter includes a valve releasably connected to the inlet opening, wherein the conduit opens the valve when the conduit extends into the collection container.

5. The handheld vacuum cleaner of claim 4 , wherein the valve includes an engagement member on an outer periphery to engage the inlet opening, and a pocket that receives and couples to the conduit.

6. The handheld vacuum cleaner of claim 1 , further comprising an actuator that is operable to uncouple the filter from the main body.

7. The handheld vacuum cleaner of claim 6 , wherein the actuator is operable such that a user can dispose of the filter without touching the filter.

8. The handheld vacuum cleaner of claim 1 , further comprising an outer housing surrounding the filter, where the outer housing includes a porous structure forming an airflow exhaust outlet.

9. The handheld vacuum cleaner of claim 1 , further comprising a battery that is at least partially disposed within the handle.

10. The handheld vacuum cleaner of claim 1 , wherein the filter is provided downstream of the suction source.

11. The handheld vacuum cleaner of claim 1 , further comprising:
a fan for creating suction through the suction inlet;
a volute surrounding the fan, the volute upstream of the filter to direct debris from the suction inlet toward the filter.

12. The handheld vacuum cleaner of claim 11 , further comprising a conduit in fluid communication with the suction inlet and connected to the filter.

13. The handheld vacuum cleaner of claim 12 , wherein the volute is operably disposed between the suction inlet and the conduit.

14. The handheld vacuum cleaner of claim 11 , wherein the motor and the suction inlet are co-axial.

15. The handheld vacuum cleaner of claim 11 , wherein the volute includes an inner periphery that is spaced circumferentially away from an outer periphery of the fan.

16. The handheld vacuum cleaner of claim 11 , wherein the suction inlet is transverse to a plane defined by the fan.

17. The handheld vacuum cleaner of claim 11 , where the volute further comprises a volute inlet, the volute inlet being aligned with the suction inlet.

18. The handheld vacuum cleaner of claim 11 , wherein the volute is operably disposed between the suction inlet and the fan dirt collection container.

19. The handheld vacuum cleaner of claim 1 , further comprising,
the suction inlet defining an inlet axis;
a conduit in fluid communication with the suction inlet, the conduit defining a conduit axis transverse to the inlet axis; and
the motor defining a rotational axis that is generally aligned with the inlet axis.

20. The handheld vacuum cleaner of claim 19 , further comprising a user interface disposed on the main body positioned on a user-facing surface.

21. The handheld vacuum cleaner of claim 20 , wherein the user interface is adjacent the handle such that a user can operate the user interface with the same hand that is grasping the handle.

22. The handheld vacuum cleaner of claim 19 , wherein the user interface is operable to control the motor.

23. The handheld vacuum cleaner of claim 19 , further comprising a fan that is driven by the motor for creating suction through the suction inlet, the fan defines a plane, and wherein the conduit axis is along the plane of the fan.

24. The handheld vacuum cleaner of claim 19 , further comprising a battery, wherein the battery is at least partially disposed within the handle.

25. The handheld vacuum cleaner of claim 1 , wherein the housing includes an upper housing configured to be supported by the handheld vacuum cleaner, wherein an end of the filter media extends away from the upper housing a desired length forming an overlapping filter media section.
