Problems solved by technology

This lateral movement requires more force for the user
When the size of the opening of a niche is significantly smaller than the width of the nozzle, suction is not possible with known nozzles, for which it is sometimes necessary to replace slit nozzles or other similar nozzles

Embodiment Construction

[0039] Firstly, a vacuum cleaner 1 with a suction nozzle 2 for treating a floor 3 is depicted and described with reference to FIG. 1 . In the illustrated embodiment the nozzle 2 is a hard floor nozzle. However, the features of the suction nozzle 2 described below are also conceivable with rotating suction nozzles for cleaning carpets.

[0040] The suction nozzle 2 basically consists of a nozzle head 4 placed on the ground 3 and a nozzle body 5 connecting the nozzle head 4 with the vacuum cleaner 1, wherein a connecting pipe 6 is constructed on the nozzle body 5 so that the suction The mouth 2 is connected to the vacuum cleaner 1 . From the connecting pipe 6 a suction channel 7 extends through the nozzle body 5 , which opens into the nozzle tip 4 . The suction opening is marked with reference numeral 8 in the figure.

[0041] The connecting pipe 6 is arranged in the upper side of an end region of the nozzle body 5 such that the connecting pipe 6 is pivotable in a first swive...

Abstract

A nozzle for a dust collecting machine, especially a nozzle for a hard floor is provided with a nozzle head part (4) placed on a floor and a nozzle main body (5) for connecting the part 4 to the dust-collecting machine. A connection short pipe (6) is formed at the main body (5), the whole nozzle (2) can be moved by traveling wheels (10) or a sliding surface and a suction duct (7) extended through the main body (5) from the pipe (6) opening at the part (4) is provided. In order to develop the nozzle of the dust collecting machine of a kind of topic in an advantageous method so as to attain, e.g., the improved suction of the peripheral part like the place along the core print and improved approachability to the corner part and the recess, the part (4) is made rotatable with respect to the main body (5).

Description

technical field [0001] The invention relates to a suction nozzle for a vacuum cleaner, especially a suction nozzle for hard floors, which has a nozzle head placed on the floor and a nozzle body for connecting the nozzle head to a vacuum cleaner, wherein a connection is formed on the nozzle body Tube and the suction nozzle can move together with the running wheel or through the sliding surface, a suction channel is arranged in the nozzle body, which extends from the connecting pipe through the nozzle body and then leads into the nozzle head. Background technique [0002] Nozzles for vacuum cleaners of the above-mentioned type are known. Correspondingly designed hard-floor suction nozzles are proposed for treating hard floors, and correspondingly designed suction nozzles are provided for treating carpeted floors, preferably with rotating bristle rollers. Suctioning in particular in alcoves, or suctioning around objects such as chair legs or table legs ...
