Abstract

Vacuum cleaner hose adapter for connecting to a vacuum cleaner hose of a wet and dry vacuum cleaner, wherein the vacuum cleaner hose has an inner lumen extending in the longitudinal direction, wherein a flow guiding geometry is formed within the vacuum cleaner hose adapter, by which a suction flow occurring during the operation of the wet and dry vacuum cleaner can be influenced.

First claim

What is claimed is:

1 - 15 . (canceled)

16 . A vacuum cleaner hose adapter for connecting to a vacuum cleaner hose of a wet and dry vacuum cleaner, the vacuum cleaner hose having an inner lumen extending in a longitudinal direction, the vacuum cleaner hose adapter comprising:
a flow guiding geometry formed within the vacuum cleaner hose adapter, the flow guiding geometry influencing a suction flow occurring during the operation of the wet and dry vacuum cleaner.

17 . The vacuum cleaner hose adapter as recited in claim 16 wherein the flow guiding geometry has a central guiding body arranged coaxially with a vacuum cleaner hose adapter longitudinal direction

18 . The vacuum cleaner hose adapter as recited in claim 17 wherein the central guiding body is designed as a solid body.

19 . The vacuum cleaner hose adapter as recited in claim 17 wherein the central guiding body has a flow channel ( 5 ).

20 . The vacuum cleaner hose adapter as recited in claim 16 wherein the flow guiding geometry has a plurality of spokes extending inwardly in the radial direction.

21 . The vacuum cleaner hose adapter as recited in claim 16 wherein the flow guiding geometry extends over a total length of the vacuum cleaner hose adapter.

22 . The vacuum cleaner hose adapter as recited in claim 16 wherein the flow guiding geometry has a cross section in the form of a sun wheel or a four-way lug wrench.

23 . The vacuum cleaner hose adapter as recited in claim 16 wherein the vacuum cleaner hose adapter is designed as an intermediate adapter.

24 . The vacuum cleaner hose adapter as recited in claim 16 wherein the vacuum cleaner hose adapter is designed as an end-located adapter.

25 . The vacuum cleaner hose adapter as recited in claim 16 further comprising a retention element.

26 . The vacuum cleaner hose adapter as recited in claim 25 wherein the retention element is a flexible retention ring.

27 . The vacuum cleaner hose adapter as recited in claim 16 wherein the vacuum cleaner hose adapter is of double-shell design.

28 . The vacuum cleaner hose adapter as recited in claim 16 wherein the vacuum cleaner hose adapter is composed of plastic.

29 . A vacuum cleaner hose for connection to a wet and dry vacuum cleaner comprising: at least one vacuum cleaner hose section and at least one vacuum cleaner hose adapter as recited in claim 16 arranged or arrangeable on the vacuum cleaner hose section.

30 . The vacuum cleaner hose as recited in claim 29 wherein the vacuum cleaner hose adapter is secured permanently on the vacuum cleaner hose.

31 . The vacuum cleaner hose as recited in claim 29 wherein the vacuum cleaner hose is designed as a spiral hose.
