Abstract (en)
[origin: DE3502064C1] Various nozzles, usually as attachments for household and industrial vacuum cleaners, are used for sucking up dust. In order to achieve a no-contact and thus gentle cleaning of objects, the plug-on nozzle is constructed in such a way that the suction flow of the vacuum cleaner produces a blowing-off flow via turbine wheels arranged successively in separate air-conducting systems. Said blowing-off flow is eddied with the flow of suction air using a conically shaped suction hood which is fitted on coaxially in order thus to achieve a controlled cleaning effect on the objects to be cleaned.
