Problems solved by technology

In suction nozzles with a rectangular suction opening, although the suction efficiency is approximately the same along the expansion of the suction opening transverse to the direction of advancement of the suction nozzle, the generally increased suction opening area leads to an undesirable and non-negligible increase in thrust
All in all, in the suction nozzles known from the prior art, there is almost without exception a satisfactory compromise between the size of the suction opening and the surface design of the suction opening, which likewise leads to an unsatisfactory suction efficiency

Embodiment Construction

[0033] figure 1 A suction nozzle known from the prior art is shown in a bottom side view of the suction nozzle. The nozzle has a base body 1 whose base 2 delimits upwardly a suction chamber 4 when the nozzle is placed on a floor 3 , the lower boundary of which is formed by the floor 3 to be sucked. The suction chamber 4 is delimited on the front side in the normal advancing direction during suction operation by a sealing lip 5 as a fluid seal. The suction chamber 4 is delimited on the rear side by a brush strip 6 . The suction channel 7 as vacuum connection opens into the suction chamber 4 in the middle of the longitudinal extent of the sealing lip 5 and at a distance from the front side. In this suction nozzle known from the prior art, the bottom side of the base 2 or base body 1 has the shape of a circular arc.

[0034] Due to the arcuate shape of the surface of the suction chamber 4 which is delimited by the sealing lip 5 and the brush strip 6 and which is subjected to n...

Abstract

The invention relates to a suction nozzle provided with a base (1), a suction port and a suction channel (7) connected to the suction port (9), wherein the suction port (9) is formed as a bottom side opening of the base (1). Dirt and / or dust absorbed together with suction air flow can be conveyed to the suction channel (9) from the floor (3) through the bottom side opening. The suction port (9) is provided with a first suction port section (10a) and at least one other suction port section (10b). The first suction port section (10a) and the other suction port section (10b) are arranged to communicate with the suction channel (7) in the base (1). In order to form a pressure gradient for passing through suction air flows, the other suction port section (10b) is arranged on a side face of the nozzle, namely, the included angle alpha between the longitudinal extension of suction port section (10b) and the longitudinal extension of the first suction port section (10a) is greater than or equal to 35 degrees and smaller than or equal to 135 degrees.

Description

technical field [0001] The invention relates to a suction nozzle with a base body, a suction opening and a suction channel connected to the suction opening, wherein the suction opening forms as an opening on the bottom side of the base body, through which dirt and / or dust absorbed by means of a suction airflow can pass. The opening on the bottom side is conveyed by the floor into the suction duct, wherein the suction opening has a first suction opening section and at least one further suction opening section, and wherein the first suction opening section and the further suction opening section Leads into a suction channel provided in the base body. Background technique [0002] Suction nozzles are known in the prior art as accessories, floor nozzles, also referred to simply as suction nozzles or, depending on the purpose of use, as hard floor nozzles or motorized brushes, and these nozzles are usually combined with manually guided, motorized vacuum cleaners Or vacuuming rob...
