In-line vacuum lquid aspirator

Abstract

An apparatus for removing fluids from a vacuum flow path comprises a body defining a containment chamber having an inlet port connectable to a vacuum hose and a barrier wall within the containment chamber isolating a transfer chamber within the containment chamber. The containment chamber has an outlet port connectable to a vacuum hose. The transfer port has a suction port fluidicly connecting the transfer chamber and the containment chamber. The apparatus further comprises a float positioned below the transfer port and adapted to be raised into sealing contact with the transfer port as a fluid level in the containment chamber rises.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of Invention[0002]The present invention relates to vacuum cleaners in general and in particular to a method and attachment for vacuuming liquids to as to prevent the liquids from entering the vacuum cleaner.[0003]2. Description of Related Art[0004]Vacuum cleaners are typically provided with a flexible hose that is connectable to a pick-up nozzle at one end and to a housing at the other end. The housing accommodates the filters for trapping the waste solid particles and an electric motor. An electrical cord for the electric motor protrudes out of the housing and is attachable to an external electric supply port. During operation, when the motor is switched on, air stream carrying the solid particles is sucked in through the nozzle and passed through the filter. The filter traps the solid particles substantially and the air stream is released back to the ambience.[0005]During the common processes of cleaning of floors and carpets by vacuum cle...

AI Technical Summary

Benefits of technology

The present invention relates to an apparatus and method for removing fluids from a vacuum flow path. The apparatus includes a body with an isolation chamber and a transfer chamber, connected by a suction port. A float is provided to engage and obstruct the transfer port when a predetermined fluid volume is reached. A baffle member is also included to support a lid and prevent fluid from splashing during use. The technical effects of the invention are improved fluid removal efficiency, reduced waste of fluids, and improved user safety.

Problems solved by technology

However, the electrical and electronic parts of the vacuum cleaners are prone to getting damaged by the liquids.

This generally makes it heavy for the user to handle and maneuver during the process of cleaning.

In such cases, the sizes of such attachments also need to be significantly small to fit into the nozzle, thereby having limited one-time liquid collecting capacity.
