Problems solved by technology

[0006] A disadvantage here is that the housing of the suction nozzle also moves due to the movement of the brush unit and here has a different distance from the surface to be cleaned.
Especially since the lifting of the housing from the hard floor to be cleaned can reach the height of the suction nozzle, said height hinders or at least hinders the cleaning of the bottom of the cabinet or the like

Embodiment Construction

[0027] figure 1 A suction cleaning device 2 with a suction nozzle 1 is shown schematically. The suction cleaning device 2 is designed as a hand-held vacuum cleaner. The suction nozzle 1 is designed as a separate accessory device which can be detached from the base device 24 of the suction cleaning device 2 . The suction nozzle 1 has a housing 3 with two wheels 30 with which the suction nozzle 1 can be moved over the surface to be cleaned. The shaft 25 is connected to the base unit 24 , and is here arranged telescopically on the base unit 24 . The shaft 25 has a handle 26 with a switch 27 . The switch 27 is here an on and off switch. Furthermore, a cable 28 is guided through the shaft 25 .

[0028] The suction cleaning device 2 conventionally has only a fan (not shown) with which suction material can be taken up and removed via the suction nozzle 1 from the surface to be cleaned. For this purpose, the fan generates a suction air flow which impinges on the suction channel ...

Abstract

The invention relates to a suction nozzle (1) of a suction cleaning device (2) having a housing (3) and a suction opening (29) for connection to the fan of the suction cleaning device (2). A suction channel (4), wherein the suction channel (4) and / or the suction opening (29) can be moved by means of an actuator (5) from a first position to a second position, in particular from a hard floor position to a carpeted floor location, and vice versa. In order to provide a suction nozzle (1), wherein the height of the suction nozzle (1) standing on the surface to be cleaned remains substantially constant, the suction nozzle (1) has a function with the actuator (5) A connected transmission (6), in particular a guide chute (6) movably arranged on the housing (3), which has a suction channel (4) and / or a suction opening ( 29) First moving means (7) for moving relative to the housing (3) and second moving means (8) for moving the seal (9), especially the brush element, relative to the housing (3). The invention also relates to a suction cleaning device ( 2 ) with a suction nozzle ( 1 ) and a method for operating the suction nozzle ( 1 ).

Description

technical field [0001] The invention relates to a suction nozzle for a suction cleaning device, said suction nozzle having a housing and a suction channel opening into the suction opening for connection to a fan of the suction cleaning device, wherein the suction The mouth and / or the suction channel can be moved by means of the actuator from a first position to a second position, in particular from a hard floor position to a carpeted position, and in reverse from the second position to the first position, in particular from a carpeted position Move to a hard floor location. [0002] Furthermore, the invention relates to an extraction cleaning device with a suction nozzle and a method for operating the suction nozzle. Background technique [0003] Suction nozzles of the above-mentioned type are known. The suction nozzle can either be arranged as an accessory device on the base device of the suction cleaning device, or it can be an inseparable part of the suction cleaning de...
