Title:
LIQUID ASPIRATOR FOR DRAWING OFF AND SUCKING UP LIQUIDS
Document Type and Number:
WIPO Patent Application WO/2012/163926
Kind Code:
A1
Abstract:
Liquid aspirator for drawing off and sucking up liquids, having a drawing-off lip (7), having a suction device for sucking up the liquid into a separating space (8) in the housing (1) of the liquid aspirator, having an exhaust-air channel (3), which is subjected to a negative suction pressure and is intended for leading the air out of the separating space (8), having a separating device (13), which is arranged in the separating space (8) and separates the liquid from the water, and having a tank for accommodating the liquid. Complex guidance of the liquid/air stream is avoided in that the housing (1) has a hollow chamber (2) which forms the separating space (8) and the tank, and into which the intake channel (4) opens and from which the exhaust-air channel (3) is guided out of the housing (1); wherein the hollow chamber (2) contains a motor-driven rotor (6) with a rotating impact surface, and the intake channel (4) is designed such that the air/liquid stream is directed for radial direction reversal and acceleration onto the impact surface.
