Liquid aspirator for drawing off and sucking up liquids

摘要

A liquid vacuuming device for drawing off and vacuuming up liquids may include a housing (1), an extractor device formed by at least one extracting lip (7) for extracting and collecting the liquid in front of at least one vacuum mouth (5), a vacuuming device that features a motor-driven vacuum subassembly and is able to vacuum an air/liquid flow mixed with the liquid to be vacuumed up along a flow pathway from the vacuum mouth (5) through an intake channel (4) into the housing (1), a separating device (13) for separating the liquid from the air and a tank for receiving the separated liquid. The device may further include an on/off function that turns on the motorized drive or increases the motor power when pressure is exerted upon the extracting lip (7) and turns off the motorized drive or reduces the motor power when the pressure decreases. Similar functionality may be implemented by an orientation switch.

1. A liquid vacuuming device for drawing off and vacuuming up liquids, including:
a housing, an extractor device, including at least one extracting lip configured to extract and collect liquid in front of at least one vacuum mouth, a vacuuming device including a motor-driven vacuum subassembly and configured to vacuum an air/liquid flow that includes the liquid to be vacuumed up along a flow pathway from the vacuum mouth through an intake channel into the housing, a separating device configured to separate the liquid from the air, a tank configured to receive the separated liquid, an exhaust air channel configured to discharge the air from the housing, and a switch configured to turn on a motorized drive of the vacuum subassembly or to increase the motor power when pressure is exerted upon the extracting lip and to turn off the motorized drive or to reduce the motor power when the pressure decreases.
