Apparatus for collection of garden waste

摘要

An apparatus for collection of garden waste wherein the apparatus has a vacuuming mode of operation and a dirty fan operation in the vacuuming mode of operation thereof, the apparatus comprising: a hand-holdable unit comprising a motor with an output shaft coupled to an impeller for generation of air flow; a volute enclosing the impeller for direction of air flow from an axial air inlet of the volute past the impeller to a tangential air outlet of the volute; a vacuum tube for conducting dirty air flow to the air inlet of the volute in the vacuuming mode of operation; and a cyclonic separation arrangement for receiving dirty air flow from the air outlet of the volute and separating garden waste from said dirty air flow in the vacuuming mode of operation. A blowervac comprising the apparatus for collection of garden waste.

主权项

1. An apparatus for collection of garden waste (W) wherein the apparatus has a vacuuming mode of operation, the apparatus comprising:
a hand-holdable unit comprising a motor with an output shaft coupled to an impeller for generation of air flow; a volute enclosing the impeller for direction of air flow from an axial air inlet of the volute past the impeller to a tangential air outlet of the volute; a vacuum tube for conducting dirty air flow to the air inlet of the volute in the vacuuming mode of operation; a cyclonic separation arrangement for receiving dirty air flow from the air outlet of the volute, separating garden waste from said dirty air flow in the vacuuming mode of operation and expelling cleaned air flow; wherein the cyclonic separation arrangement comprises: a cyclone having a hollow generally cylindrical cyclone body (54) with a longitudinal central axis; a tangential air inlet port through a side of the cyclone body to generate a vortex in the cyclone body with dirty air flow received from the air outlet of the volute; an air outlet port through a first longitudinal end of the cyclone body for expelling cleaned air flow; means for collecting garden waste (W) separated from said dirty air flow by the cyclone; and wherein the central axis of the cyclone body and an axis of rotation of the impeller are substantially parallel.
