Abstract
A hand-held cleaning device that utilizes a low-power, low-torque motor coupled to an impeller for creating a vacuum. The device includes a contact head having a plurality of protrusions formed on its top surface. The contact head contacts the surface to be cleaned, for example, the coat of a pet. The protrusions are sized and spaced to avoid tangling or clumping of pet hair. The device includes a container for collecting hair and debris. The impeller includes ribs on a disk portion thereof for increasing the efficiency of the vacuum system.
Claims19
A hand-held cleaning device, comprising:
- a housing having a swirl chamber;
- an impeller mounted in the swirl chamber;
- a motor for driving the impeller;
- and
- a contact head mounted to the housing upstream of the impeller for loosening debris to be collected by the device, said contact head comprising a contact surface having a plurality of protrusions formed thereon, wherein the ratio of the height of each protrusion to the width of each respective protrusion at its widest portion is less than 1.
A hand-held cleaning device, comprising:
- a housing having a swirl chamber;
- an impeller mounted in the swirl chamber;
- a motor for driving the impeller;
- a contact head mounted to the housing upstream of the impeller for loosening debris to be collected by the device, said contact head comprising a contact surface having a plurality of protrusions formed thereon;
- and
- a collection container having a first end and a second end, wherein the first end includes a first opening that is coupled to the swirl chamber for receiving debris and wherein the second end includes a hinged door for closing a second opening, wherein collected debris may be evacuated from the collection container when the hinged door is open.
A hand-held cleaning device, comprising:
- a housing having a swirl chamber;
- an electric motor;
- at least one source of electric power connected to the motor;
- an impeller coupled to said motor and disposed in said swirl chamber, comprising a disk portion and a plurality of impeller blades attached to a bottom surface of said disk portion;
- wherein a top surface of said disk portion includes at least one rib extending from the center of said disk portion to the edge of said disk portion.
