AI Technical Summary

Problems solved by technology

If a suction device with a weaker suction unit is used, this can lead to a significant deterioration of the suction performance of the suction nozzle
The suction performance on hard floors deteriorates particularly significantly if the suction nozzle is used with a low-power suction unit for suction not only on smooth floors but also on tiled floors

Abstract

The present invention relates to a suction nozzle of a floor vacuum cleaner. The suction nozzle comprises a suction head, a suction pipe connecting piece, a sliding base plate, at least one supporting sealing element, and a control element that can reach the suction head. The suction pipe connecting piece can be pivotally connected to a suction channel around a pivot axis. The sliding base plate comprises at least one suction port defined by an edge of the suction port at the lower side. The supporting sealing element is fixed to a support that can be vertically adjusted for vertically adjusting the support between at least two functional positions. The supporting sealing element is lifted so far in the first functional position so as to abut the sliding base plate on a fabric ground. The supporting sealing element is decreased in the second functional position and supports the suction head on the firm ground so as to form a gap between the edge of the suction port and the firm ground. The gap between the edge of the suction port and the firm ground can be adjusted between two different preset values.

Description

technical field [0001] The invention relates to a suction nozzle for a floor vacuum cleaner, which has a suction head, a suction pipe connection, a sliding base, at least one bearing sealing element and a control element accessible on the suction head, the suction pipe connection being able to rotate around a pivot The axis of rotation is pivotally connected to the suction channel of the suction head, the sliding bottom plate has at least one suction opening defined on the underside by the suction opening edge, the supporting sealing element is fixed on a vertically adjustable bracket, the control element is used for Vertical adjustment of the support between at least two functional positions. In the first functional position for cleaning the fabric floor, the bearing sealing element is raised so far that the sliding base rests on the fabric floor. In a second functional position for cleaning hard floors, the support sealing element is lowered and supports the suction head on...
