Abstract:
Disclosed is a self-cleaning roller cleaning apparatus, comprising an apparatus main body (10), a drive mechanism, a cleaning roller (20) and a cleaning brush (30), wherein the cleaning roller (20) is arranged in the apparatus main body (10) and exposed from the bottom of the apparatus main body (10); the apparatus main body (10) is internally provided with a holding cavity (11); the holding cavity (11) is arranged close to the cleaning roller (20), and is used for holding the dirt that is spun away from a surface of the roller; the cleaning brush (30) is rotatably arranged between the cleaning roller (20) and the holding cavity (11) and abuts against the roller; and both the roller and the cleaning brush (30) are in transmission connection with the drive mechanism. In this way, the cleaning brush (30) can be driven by the drive mechanism to rotate relative to the surface of the cleaning roller (20) and in turn brush the dirt on the surface of the cleaning roller (20) into the holding cavity (11) so as to thoroughly remove the dirt left on the cleaning roller (20). The cleaning roller (20) only needs to be rolled across a surface to be cleaned, such as the ground, once to achieve efficient and thorough collection and removal of the dirt therefrom, thereby significantly improving the cleaning efficiency thereof.
