Abstract

A handheld vacuum cleaner having a housing with an electric motor, a fan driven by the motor, a debris emptying hole for removal of debris from a debris collecting compartment inside the vacuum cleaner, a lid pivotally hinged about a pivot axis and adapted to allow closing and opening of the debris emptying hole, a nozzle defining a nozzle opening in a forward end of the vacuum cleaner through which an air stream may be drawn for collecting debris, and at least two wheels, which are positioned adjacent the nozzle opening and are rotatable about a common rotation axis. The pivot axis for the lid and the rotation axis for the wheels are located on a common axis.

Claims

1. A handheld vacuum cleaner comprising:

a housing having an electric motor and a fan driven by the motor, a debris emptying hole for removal of debris from a debris collecting compartment inside the vacuum cleaner, a lid being pivotally hinged about a pivot axis and adapted to allow closing and opening of the debris emptying hole, a nozzle defining a nozzle opening in a forward end of the vacuum cleaner through which an air stream may be drawn for collecting debris, and at least two wheels, which are positioned adjacent the nozzle opening and are rotatable about a common rotation axis, wherein the pivot axis for the lid and the rotation axis for the wheels are located on a common axis.

2. The handheld vacuum cleaner according to claim 1, wherein the pivot axis and the rotation axis are formed by two separate shaft pieces that are collinearly aligned with each other.

3. The handheld vacuum cleaner according to claim 2, wherein the shaft pieces have outer ends that are directed outwards in opposite directions.

4. The handheld vacuum cleaner according to claim 2, wherein the wheels and the lid are separately mounted to the shaft pieces, and the wheels are mounted on the shaft pieces inwardly of the lid.

5. The handheld vacuum cleaner according to claim 4, wherein the lid has a generally U-shaped portion having two legs, and wherein each leg is mounted over a respective shaft piece, and pivotally attached on the shaft pieces by pivoting mount.

6. The handheld vacuum cleaner according to claim 2, wherein the shaft pieces are positioned more distally, as compared to the nozzle opening, from the forward end of the vacuum cleaner.

7. The handheld vacuum cleaner according to claim 2, wherein the housing spaces in which the wheels are mounted, each space being defined between a central portion of the housing and a respective mounting wall located adjacent the central portion of the housing.

8. The handheld vacuum cleaner according to claim 7, wherein the shaft pieces pass through respective hole through the mounting walls, through the respective wheel, and into respective holes in the housing, and a portion of each shaft piece protrudes outside the mounting wall to define shaft end portions onto which the lid is pivotally mounted.

9. The handheld vacuum cleaner according to claim 1, wherein the lid at least partly surrounds the nozzle opening and forms part of a rim surrounding the nozzle opening.

10. The handheld vacuum cleaner according to claim 1, wherein the wheels are at least partly covered by the lid.

11. The handheld vacuum cleaner according to claim 1, wherein the lid is pivotally opened by rotating it towards the forward end of the vacuum cleaner.

12. The handheld vacuum cleaner according to claim 1, wherein the housing and the lid are comprise stop means to limit the pivoting movement of the lid.
