Abstract
A disposable bag for removal of dust vacuum cleaners comprised of a nonporous polymer composition sheeting sealed water tight for internally containing a quantity of water that functions as the dust removal media. The bag is configured for mounting internally within the external fabric bag customarily provided by the vacuum cleaner manufacturer. Discharge of dust laden air from the vacuum blower is connected to an air inlet on the bag from which an internal guide directs the air flow to within the body of water. Emerging from the water substantially dust free, the air is directed past baffles to eliminate entrained moisture before being discharged through an outlet opening to the surrounding environment.
Claims8
A disposable dust collection bag for use internally of the dust collection compartment of a vacuum cleaner apparatus and comprising in combination:
- an elongated collection bag of nonporous composition defining an internal compartment having a portion in which to contain a body of liquid comprising the dust collection media, said bag being of a size and shape adapted to be received internally of the vacuum cleaner dust collection compartment with which the collection bag is to be utilized;
- inlet means defined in said collection bag at a location above the normal liquid level and adapted to receive dust laden air from the vacuum cleaner;
- conduit means extending downwardly internally of said collection bag in communication with said inlet for discharging the received dust laden air flow to a location within the body of liquid in said compartment portion;
- and
- outlet means defined in said collection bag at a location removed from the contained body of liquid through which air flow emerging from the body of liquid can be discharged relatively dust free to atmosphere.
In a vaccum cleaner apparatus having vacuum generating means and a collection compartment through which vacuum air is passed for collection of dust particles therefrom, a disposable dust collection bag for liner use within said collection compartment and comprising in combination:
- an elongated collection bag of nonporous composition defining an internal compartment having a portion in which to contain a body of liquid comprising a dust collection media;
- inlet means defined in said collection bag at a location above the normal liquid level and adapted to receive dust laden air from the vacuum cleaner;
- conduit means extending downwardly internally of said collection bag in communication with said inlet for discharging the received dust laden air flow to a location within the body of liquid in said compartment portion;
- and
- outlet means defined in said collection bag at a location removed from the contained body of liquid through which air flow emerging from the body of liquid can be discharged relatively dust free to atmosphere.
