Abstract (en)
[origin: WO2021233660A1] The invention relates to a suction device comprising a suction head (20), a suctioned material container (12) for receiving a suctioned material, a suction fan device (22) which is arranged on the suction head (20), and a channel device (96) which is paired with the suction fan device (22) for conducting process air to the suction head (20), wherein the channel device (96) has at least one first air outlet (102) and a second air outlet (104), and the channel device (96) has a first channel (106) paired with the first air outlet (102) for supplying air to the first air outlet (102) and a second channel (108) paired with the second air outlet (104) for supplying air to the second air outlet (104). A tube element (186a) with an adapter device (186) is provided. The adapter device (186) is fluidically connected or can be fluidically connected to a suction connection (34) of the suction device in a releasable manner in order to carry out a suction process, and the adapter device (186) is fluidically connected or can be fluidically connected to the first air outlet (102) in a releasable manner in order to carry out a blowing process. An air inlet opening (160) of the second channel (108) for supplying process air from the suction fan device (22) to the second air outlet (104) is closed by at least one wall element (189) of the adapter device (186) when the adapter device (186) is properly connected to the first air outlet (102).
