Embodiment Construction

[0022] figure 1 An extraction cleaning device 2 with a suction nozzle 1 is shown by way of example. The suction cleaning device 2 is embodied as a hand-held vacuum cleaner. The suction nozzle 1 has a housing 7 and is designed as a separate accessory device which can be detached from the base device 13 of the suction cleaning device 2 . The suction cleaning device 2 has a telescoping shaft 15 which is connected to the base device 13 in the usual manner. Arranged on the shaft 15 is a handle 16 with a switch 17 for switching the fan of the suction cleaning device 2 on and off. Furthermore, a cable 18 for connecting the fan motor to a power supply is inserted into the shaft 15 . A dust collection chamber (not shown) is constructed in the basic device 13, in which the sucked matter sucked through the suction nozzle 1 can be collected. The suction nozzle 1 is connected to the suction connection 14 of the basic device 13 , so that suction can be sucked from the surface to be clea...

Abstract

The invention relates to a suction nozzle (1) for a vacuum cleaning device (2). The suction nozzle (1) has a suction mouth (3) and a suction channel (4) for connecting the suction mouth (3) to a blower of the vacuum cleaning device (2), wherein the suction nozzle (1) comprises a sensor (5), which is movably mounted on a housing (7) of the suction nozzle (1) and is used for detecting the nature of a surface (6) to be cleaned. The suction channel (4) moves relative to surface (6) depending on the detection result of the sensor (5), in particular from a hard bottom position to a carpet position or vice versa. In order to improve the detection result of the sensor (5), it is proposed that the sensor (5), which is in a normal operation state in the suction nozzle, has permanent contact with the surface (6) regardless of the type of surface (6) and moves on the basis of a frictional force between the surface (6) and the sensor (5).

Description

technical field [0001] The invention relates to a suction nozzle for a suction cleaning device, the suction nozzle having a suction opening and a suction channel for connecting the suction opening to a fan of the suction cleaning device, wherein the suction nozzle has A sensor movably supported on the housing of the suction nozzle is used to detect the type of surface to be cleaned, and wherein the suction channel can be moved relative to the surface according to the detection result of the sensor, especially from a hard floor position to a Carpet floor position or vice versa moving from a carpet floor position to a hard floor position. [0002] Furthermore, the invention relates to an extraction cleaning appliance, in particular a household vacuum cleaner, which has a suction nozzle of the above-mentioned type. Background technique [0003] Suction nozzles for suction cleaning appliances are known in the prior art. Depending on the type of accessory device, the suction no...
