CROSS REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims the benefit of U.S. Provisional Application 62/979,737 filed February 21, 2020.
FIELD OF THE INVENTION
[0002] The field of the present invention generally relates to hand-held battery powered vacuum devices. In particular a device for the sanitary collection and disposal of solid pet waste.
BACKGROUND OF THE INVENTION
[0003] Cleaning up after pets is a chore. Whether you clean up after every bathroom break or come back to tackle a yard full of accumulated waste there has been no clean and easy way to get this job done. Classic tools include a hand shovel, pooper scooper (with pinching blades closing below the waste), and individual plastic poop bags (flipped inside-out with your hand inside). The tools all come into direct contact with the waste, dirtying the tools and requiring them to be sanitized regularly. The inside-out poop bag is probably the most sanitary solution (although it can feel gross to hold waste through a thin barrier), but it only works well for a single pile of waste. It would be very difficult to use the small bags for a yard’s worth of accumulated waste, and therefore results in the use of a lot of disposable plastic over time.
[0004] One inventor, Tory Reynolds, has developed a basic sanitary vacuum product, marketed as the Power Pooch Shovel by Pet Power Products LLC (detailed product information available at https://petpowerproducts.com/shop/product/pooch- power-shovel-3/), while this advancement is a good first step toward a novel solution, the device itself has presented with many clear drawbacks that the present application seeks to build-upon and remedy to create a gold standard vacuum based solid pet waste solution.
SUMMARY OF THE INVENTION
[0005] The present invention uses vacuum suction to collect solid pet waste into sanitary disposable filter bags. The filter bags cover the intake and prevent solid pet waste from escaping into the collection chamber, allowing waste to be collected with minimal mess. Furthermore, using vacuum power to collect solid pet waste from the grass or ground will avoid the smearing and smashing that often results from using a shovel, pooper scooper, or individual plastic bags - ground and grass alike should be left as clean as possible. For convenience and ease of use, the unit is battery operated and rechargeable.

DETAILED DESCRIPTION
[0015] The invention shown in Fig. 1, Fig. 6 and Fig. 7 is one embodiment of a hand-held solid pet waste vacuum featuring an intake 1001, a lower collection chamber 1003, an upper collection chamber 1009, a collection chamber hinge 1002, two attachment nuts 1005, 1006, an extension tube 1004, a front handle 1007, and a top handle 1008.
[0016] The invention further shown in Fig. 3 reveals a power port for recharging 1010. The invention further shown in Fig. 4 and Fig. 5 further reveals a power on/off switch 1011.
[0017] The invention further shown in Fig. 8 shows the interior of the upper collection chamber 1009 and lower collection chamber 1003, in particular a bag flange 1012 to secure the disposable waste bag.
[0018] In one embodiment of the present invention, a hand held solid pet waste vacuum can be configured with a 22,000 rpm or 30,000 rpm motor (to quickly suction dog waste from grass, concrete, or even snow-covered ground into a plastic bag that removes for ease of waste disposal). In a further embodiment, the collection bag wraps around the vacuum’s intake to prevent waste from touching any part of the device. In a further embodiment the collection bag can be biodegradable. In a further configuration of the present invention, it can provide up to 50 cleanups after a 12-hour charge via the included AC adapter. In a further configuration each disposable bag holds roughly a week’s worth of solid waste.
[0019] In a further embodiment of the present invention, the lower collection chamber could have one or more small wheels on its base. In a further embodiment of the present invention the lower surface of the lower collection chamber could have one or more raised ridges running front to back allowing easier movements along the ground.
