发明名称 Debris removal apparatus for power blowers
摘要 A hollow tubular nozzle for attachment to power blowers or "leaf blowers" has a depending rectangular mounting flange extending transversely across its underside, the bottom portion of which is adapted to removably receive and retain a debris and trash loosening attachment member in the form of a brush or scraper blade which forcefully engages the surface to be cleaned to dislodge debris and trash therefrom while preventing damage to the nozzle from contacting the surface. The mounting flange may be integrally formed on the nozzle, or it may be a separate piece having a top portion conforming to the configuration of existing rectangular or round nozzles and adapted to be secured thereto. The mounting flange, brush and scraper attachments may be sold as a do-it-yourself kit to be installed on the existing nozzles. The user may simply install and remove the brush or scraper blade onto the mounting flange when desired. Another embodiment of the brush and scraper attachments have a top portion adapted to be received and retained on the nozzle by means of spring clip members.
