发明名称 Liquid aspirator
摘要 The use of liquid aspirators which are connected to conventional vacuum cleaners is known. In this invention a reservoir-body of an elongated form extends at its lower part to a nozzle, and at its upper part to a lid which is provided with an end-piece for the attachment of an external hose from a conventional vacuum cleaner. The said lid is placed on the inside of a lid-handle which extends above the reservoir-body. A tube following the nozzle penetrates into the interior of the elongated body-reservoir to discharge the liquid, where in the interior of the said body spacers and separators are provided, while a transparent window permits viewing the level of the liquid and a float closes the air vacuum when the level of the liquid reaches a predetermined value. Some baffle-plates and a filter are provided to prevent sprayed drops of water from being drawn towards the vacuum cleaner and damaging its electric motor.
