Abstract

A stick vacuum cleaner comprising an elongated shaft part, a housing arranged to be attached to the elongated shaft part, the housing comprising an air inlet, a container arranged to accommodate a removable air-permeable dust bag, a motor fan unit for creating an airflow, and an exhaust air outlet, a nozzle arranged at a first end of the elongated shaft part, the nozzle comprising a nozzle inlet via which debris is transported from a surface to be cleaned by means of the created airflow to the dust container, and a handle arranged at a second end of the elongated shaft part, wherein the container is arranged to be removably attached to the housing.

First claim

The invention claimed is:

1. A stick vacuum cleaner comprising:
an elongated shaft part;
a housing configured to be attached to the elongated shaft part, the housing comprising an air inlet, a container configured to accommodate a removable air-permeable dust bag, a motor fan unit configured to create an airflow, and an exhaust air outlet;
a nozzle arranged at a first end of the elongated shaft part, the nozzle comprising a nozzle inlet configured to transport debris from a surface to be cleaned to a dust container by means of the created airflow; and
a handle arranged at a second end of the elongated shaft part; wherein:
the container is configured to be removably attached to the housing and comprises
an aperture configured to be openable for facilitating removal of the removable air-permeable dust bag, and a bracket configured to accommodate the removable air-permeable dust bag and including at least one spring-loaded member configured to block the aperture from being closed when no removable air-permeable dust bag is placed in the bracket, wherein the removable air-permeable dust bag is configured to press against the spring-loaded member when placed in the bracket, causing a spring of the spring-loaded member to compress and move the spring-loaded member in a transversal direction towards an interior of the container, thereby allowing the aperture to be closed, and wherein removal of the removable air-permeable dust bag causes the spring to expand and move the spring-loaded member in a transversal direction towards an exterior of the container, thereby blocking the aperture from being closed.

2. The stick vacuum cleaner of claim 1 , wherein the aperture further comprises at least one flange configured to press against the removable air-permeable dust bag upon a user closing the aperture.

3. The stick vacuum cleaner of claim 1 , wherein the container further comprises a push-button configured to snap open the aperture upon a user pressing the push-button.

4. The stick vacuum cleaner of claim 1 , wherein the container further comprises a container air outlet arranged in a bottom section of the container and configured to mate with a motor fan inlet that is in fluid communication with the exhaust air outlet.

5. The stick vacuum cleaner of claim 1 , wherein the air inlet is arranged in a top section of the container and configured to mate with a shaft air outlet arranged on the elongated shaft part and in fluid communication with the nozzle.

6. The stick vacuum cleaner of claim 1 , wherein the container further comprises a snap-in mechanism configured to removably attach the container to the housing.

7. The stick vacuum cleaner of claim 1 , wherein the container further comprises elongated protruding members arranged on an interior wall of the container.

8. The stick vacuum cleaner of claim 4 , wherein the container further comprises one or more protruding members arranged at the air outlet of the container.

9. The stick vacuum cleaner of claim 1 , wherein the dust container further comprises a visual indicator configured to indicate to a user a degree of fullness of the removable air-permeable dust bag.

10. The stick vacuum cleaner of claim 1 , wherein the container further comprises a push-button configured to release the container from the housing upon a user pressing the push-button.

11. The stick vacuum cleaner of claim 1 , wherein the container comprises airtight walls.

12. The stick vacuum cleaner of claim 11 , wherein at least some part of the airtight walls constitute the vacuum cleaner housing.

13. The stick vacuum cleaner of claim 1 , wherein the removable air-permeable dust bag a connector plate configured to engage with the bracket.

14. The stick vacuum cleaner of claim 11 , wherein a majority of the airtight walls constitute the vacuum cleaner housing.

15. The stick vacuum cleaner of claim 7 , wherein the elongate protruding members are arranged along a longitudinal axis of the container.

16. The stick vacuum of claim 1 , wherein the housing is attachable and detachable to the elongated shaft part at a first position on the elongated shaft part and a second position along the elongated shaft part.

17. The stick vacuum of claim 1 , wherein the housing is slidable along the elongated shaft part between a first position on the elongated shaft part and a second position along the elongated shaft part.

18. The stick vacuum of claim 1 , wherein the housing is slidable along and attachable to the elongated shaft part at any position along the length of the elongated shaft part.

19. The stick vacuum of claim 18 , wherein the housing comprises a latch configured to fix the housing in a selected position along the length of the elongated shaft part and release the housing to slide along the elongated shaft part when the latch is opened.

20. The stick vacuum of claim 1 , wherein the housing comprises a handle that can be operated by a user to move the housing along or from the elongated shaft part.
