COMPACT DUST BAG FOR A VACUUM CLEANER

Abstract

A vacuum cleaner dust bag having a connector plate comprising a hole section, an air permeable filter bag positioned on a downstream side of the connector plate, and a flexible sleeve. The filter bag is attached to the connector plate and the sleeve is provided outside the filter bag. The sleeve is arranged to keep the filter bag in an initial folded position and allow the filter bag to expand when air is blown through a hole formed in the hole section of the connector plate.

Description

Claims

1. A dust bag for a vacuum cleaner comprising: a connector plate comprising a hole section;a filter bag of an air-permeable material positioned on a downstream side of the connector plate; anda sleeve of a flexible material positioned on the downstream side of the connector plate outside the filter bagwherein the sleeve is arranged to hold the filter bag in an initial folded position and allow the filter bag to expand when air is blown towards the downstream side of the connector plate through the hole section of the connector plate.

2. The dust bag according to claim 1, wherein the filter bag is connected to the connector plate at filter bag sides, and the sleeve surrounds an entirety of the sleeve sides when the filter bag is in the initial folded position.

3. The dust bag according to claim 1, further comprising a guide on the connector plate, the guide being configured -to assist in correctly positioning the dust bag in a vacuum cleaner.

4. The dust bag according to claim 3, wherein the guide is formed by a flange and/or aperture in the outer perimeter of the connector plate.

5. The dust bag according to claim 4, wherein the flange extends all around a perimeter of the connector plate.

6. The dust bag according to claim 1, wherein the hole section comprises a perforation in the connector plate, the perforation being configured to form a hole in the connector plate.

7. The dust bag according to claim 1, wherein the hole section comprises a hole in the connector plate.

8. The dust bag according to claim 1, wherein the filter bag does not extend further than the connector plate as seen in a direction perpendicular to the axial direction of the connector plate.

9. The dust bag according to claim 1, wherein the sleeve is formed by a paper material.

10. The dust bag according to claim 1, wherein the sleeve is made of a non-air permeable material.

11. The dust bag according to claim 1, wherein the hole section comprises a sealing configured to form an air tight connection to a vacuum cleaner when the dust bag is placed in the vacuum cleaner and a hole is in the hole section.

12. The dust bag according to claim 1, wherein the sleeve is attached to the connector plate.

13. The dust bag according to claim 1, wherein the sleeve is folded in an end distanced away from the connector plate.

14. A vacuum cleaner comprising a dust bag holder, wherein the dust bag holder is configured to receive a dust bag according to claim 1 .

15. A vacuum cleaner according to claim 14, wherein the dust bag is configured to be placed in the dust bag holder and wherein the vacuum cleaner is configured to blow air through the dust bag such that air is blown axially from a hole in the connector plate through the dust bag.

16. The dust bag according to claim 1, wherein the filter bag and the sleeve are connected to the connector plate.

17. The dust bag according to claim 1, wherein the sleeve comprises: a proximal end attached to the connector plate;sidewalls extending from the proximal end and surrounding sides of the filter bag in the initial closed position; anda distal end extending from the sidewalls, wherein the distal end is movable from a closed position in which the distal end encloses an end of the filter bag, and an opened position in which the distal end does not enclose the end of the filter bag, and wherein the distal end is configured to move from the closed position to the open position upon application of a suction force.

18. The dust bag according to claim 17, wherein the distal end is folded in the closed position, and unfolded in the opened position.

19. The dust bag according to claim 17, wherein the distal end is held in the closed position by glue.

20. The dust bag according to claim 17, wherein the sidewalls and distal end completely enclose the entire filter bag when the filter bag is in the initial closed position and the distal end is in the closed position.
