Liquid aspirator for drawing off and sucking up liquids

A suction device for drawing off and sucking up liquids, including:

• a casing;
• a removal device, formed at least of a suction nozzle and a leveling blade, for the removal and collection of the liquid before at least the suction nozzle, wherein the leveling blade is connected to the casing in a movable manner, by moving bearings that include a switch, the moving of which can switch the leveling blade between an OFF and an ON setting, and whereby a motor drive is configured to be switched on and off by the switch;
• a separation chamber located in the casing;
• a suction device configured to guide an air and liquid flow that includes the liquid intended for removal via a flow trajectory from the suction nozzle through an intake duct into the separation chamber;
• a negatively pressured exhaust air duct configured to guide air out of the separation chamber;
• a separation device located inside the separation chamber which, in order to separate the liquid from the air, is configured to divert the air and liquid flow;
• a tank configured to collect the separated liquid,
• whereby wherein the casing includes a hollow chamber linking the separation chamber with the tank, into which the intake duct opens, and in which the separation device is arranged in such a way that the sucked-in air and liquid flow is diverted into the tank, the air duct is in a flow connection with the tank,
• wherein the separation device is formed by a flow guide on an air intake side in the form of a stator or a rotor configured to be driven by the motor drive, which is positioned in the tank on the intake duct or inside the tank before the intake of the air and liquid flow, and which is configured to radially guide the sucked-in air and liquid flow outwards into the tank, and
• further including a flow labyrinth, positioned before an intake into the air duct and configured to hold back spray water from entering the air duct.
