Abstract
A filter apparatus. The filter apparatus further comprises a filter, a canister, and a trigger, wherein the trigger permits or prevents airflow through the filter.
Description
- This Application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/843,159, filed on Jul. 5, 2013, incorporated herein in its entirety by reference.
- The present invention is directed to a filter attachment for a cleaning apparatus and, more particularly, to a HEPA filtration system that may be used in conjunction with a vacuum cleaner or sweeper machine.
- From time to time, a person may use a vacuum or sweeper machine to clean a mess that has a bad odor, is partially or completely liquid, or has other properties that make it undesirable to store in a standard vacuum bag or canister. In order to clean this mess, the person must use a specialized machine made for a specific purpose or clean the mess by hand.
- Of particular interest is the lack of a means in the art to clean, collect, or vacuum odorous insects such as “stink bugs” (insects of the families Pentatomidae and Rhopalidae, for example) without causing the insects to release a foul odor. When these insects are disturbed or damaged, they secrete a foul-smelling cyanide-based liquid which can permanently contaminate the inner workings of a machine such as a vacuum cleaner and can cause a residence or workplace to have a foul smell over time.
- Vacuum cleaners containing an internal HEPA filtration system are available for purchase separately, however they are not designed to prevent odors from escaping the bag or canister and are directed to reducing dust and allergens. They are further unable to accommodate liquid messes. These teach away from the present invention because they require the person to purchase and maintain multiple machines to accomplish different purposes.
- Machines which divert liquids into a canister by means of suction, often known as “wet/dry vacs” are commercially available. These teach away from the present invention because they focus their cleaning ability on non-dry debris and are often unsuitable for a high level of cleaning, for example, in a soiled residential carpet. They are further not directed at preventing odors from escaping the canister and are directed towards dust management. Notably, the high suction forces created by these machines cause substantial damage to stink bugs, increasing the smell released even as the insects are swept up.
- The present invention resides in one aspect in a filtration apparatus. The filtration apparatus has a handle, a filter, and a canister. The handle has a trigger which permits or prevents air flow through the filters. The canister collects debris prior to air filtration.

FIG. 3 , in one embodiment, thefilter 410 is enclosed within afilter case 440. In one embodiment, afilter gasket 442 is disposed between thefilter case 440 and anouter surface 642 of thecontainer outlet 640. In one embodiment, thefilter 410 and thefilter case 440 form a “sealed HEPA” system whereby no air may travel in Direction C without passing throughfilter 410. - As shown in
FIGS. 2A and 2B , thetrigger assembly 300 receives the air leaving thecanister 600 through thefilter 410 at thetrigger inlet 332 along Direction C. As shown inFIG. 2B , thetrigger assembly 300 is in the closed position. In one embodiment, atrigger valve 340 is large enough to block thetrigger outlet 330. In one embodiment, atrigger gasket 342 is disposed between thetrigger valve 340 and anoutlet surface 344. - As shown in
FIG. 1 , thetrigger assembly 300 is in the open position allowing air to travel in Direction C from thecanister 600 to thetrigger outlet 330. - Referring to
FIG. 2B , atrigger 310 has astem end 312, apivot point 314, and anoperational end 316.
