Portable blower with wear resistant discharge end

摘要

A portable blower having a propulsion unit for continuously generating a supply of pressurized fluid and a conduit assembly for controllably directing fluid from the propulsion unit to and through a discharge opening on the conduit assembly. The discharge opening is bounded by a rim, defined at least partially by a discrete component made from a first material. The conduit assembly has a first portion made from a second material to which the discrete component is operatively connected. The first material is at least one of: a) more resistant to abrasive wear than the second material; b) more resistant to impact than the second material; and c) harder than the second material.

1. A portable blower comprising:
a propulsion unit for continuously generating a supply of pressurized fluid; and a conduit assembly for controllably directing fluid from the propulsion unit to and through a discharge opening on the conduit assembly, the discharge opening having a central axis and a diameter, the discharge opening bounded by a rim, the rim defined at least partially by a discrete component made from a first material, the discrete component extending axially relative to the central axis a distance less than the diameter of the discharge opening, the conduit assembly comprising a first portion made from a second material to which the discrete component is operatively connected, the first material being at least one of: a) more resistant to abrasive wear than the second material; b) more resistant to impact than the second material; and c) harder than the second material, wherein the discrete component is in the form of a ring, wherein air moving through the discharge opening moves in a first line, the first portion of the conduit assembly defines a first edge on the rim facing in one direction generally parallel to the first line and the discrete component defines a second edge that extends transversely to the first line and abuts to the first edge with the discrete component operatively connected.
