Embodiment Construction

[0019] figure 1 Shows a suction nozzle 1 for a floor vacuum cleaner according to the invention, wherein the housing channel 2 forms the first part of the air guiding channel and the rear connection 3 with the rotatable suction pipe receiver 4 forms the air Guide the second part of the channel. The rear end of the housing channel 2 comprises an outer joint part 5 into which an inner joint part 6 of the connecting part 3 is inserted so as to be movable on an axis of rotation 8 defined by a pivot pin 7 . Such as Figure 2a with 2b As shown in the detailed view of , the outer joint part 5 and the inner joint part 6 are sealed by a flexible sealing lip 9 formed on the outer joint part 5 and surrounding the outer surfaces 10a, 10b, 10c of the inner joint part 6 . The end of the sealing lip 9 , ie the end pointing towards the rear of the suction nozzle 1 , is free and is therefore directly exposed to the ambient pressure. During use of the nozzle 1, the sealing lips 9 are drawn b...

Abstract

The invention relates to a nozzle used in a floor vacuum dust collector which includes a first part of an air guide chunnel. The first part is movably connected with a second part of the air guide chunnel with rotary method, one end of the first part of the air guide chunnel limits an exterior joint member, an inner joint member of the second part of the air guide chunnel is inserted into the exterior joint member for moving on a rotary axes, and the exterior joint member and the inner joint member are sealed through a flexible sealing lip. All sealed lips provided between the first and second parts of the air guide chunnel forms on the exterior joint member and encloses exterior surface of the inner joint member at least partly. In use process of the nozzle, free end of the seal lip is shocked by environment pressure, so leans against exterior surface of the inner joint member for providing seal. The first and second parts of the air guide chunnel can be designed, for example, a joint member of a casting chunnel and the nozzle.

Description

technical field [0001] The invention relates to a suction nozzle for a floor vacuum cleaner comprising a first part of an air guiding channel movably connected in a rotatable manner to a second part of the air guiding channel, wherein one end of the first part of the air guiding channel defines An outer joint part is provided, into which the inner joint part of the second part of the air guide channel is inserted so as to be movable on the axis of rotation, and wherein the outer and inner joint parts are sealed by a flexible sealing lip. Background technique [0002] In nozzles for floor vacuum cleaners, a good seal between the individual components forming the air duct is important, on the one hand to avoid unpleasant air noise, on the other hand to achieve a good negative pressure and Good suction performance. This is especially important when the nozzle is used in floor vacuum cleaners to increase energy efficiency by reducing the secondary air fraction. Within the scop...
