BRUSH ENTANGLEMENT PREVENTION APPARATUS IN AUTONOMOUS ROBOTIC VACUUMS

摘要

An apparatus draws or leads hair and other potential entanglement debris away from the hub of a brush assembly in a vacuum as the brush rotates during vacuuming, thus avoiding or reducing entanglement and attendant problems, and obviating or reducing the need for manual removal of the entanglement. The apparatus has a profile which draws hair and other entanglement debris away from a hub of the brush assembly, or prevents it from reaching the hub, thus enabling the brush/brush assembly to continue to rotate freely. In one implementation, the apparatus attaches to a vacuum brush in an autonomous robotic vacuum.

主权项

1. A brush entanglement prevention apparatus comprising:
a first endpiece having a first, beveled side; a second endpiece; and an insert fitting between said first and second endpieces, said insert having a generally circular portion with a beveled insert side having a contour matching that of the first, beveled side of the first endpiece, the insert further having an extension that extends from the beveled insert side and extends through the first endpiece into an opening in an elongate brush assembly, such that the first beveled side of the first endpiece faces the elongate brush assembly; the first endpiece having a second, complementary side facing the insert, the second, complementary side having a surface generally fitting around the beveled insert side; the arrangement being such that the first, beveled side of the first endpiece prevents entanglement of hair that otherwise would prevent rotation of the brush assembly.
