STANDALONE PORTABLE ELECTRIC BLOWER WITH VARIABLE AIR EXIT SPEED
First Claim
1. Stand-alone portable electric blower, featuring at least one propeller generating an an flow and driven by an electric motor powered by a current source, said blower comprising an air-guide conduit consisting of three successive tubular parts of a general cylindrical shape, namely a proximal part or suction nozzle ti provided with an in inlet, a distal air outlet part or exhaust pipe and a central or intermediary part, characterized in that the central pan is a separate piece and is fitted to constitute a functional assembly solid bloc or formed by an assembly of a number of elements and made of a good heat-conducting material, said central part featuring the following functional sub-assemblies housed in said central part of said air-guide conduit:
- an electric motor with electronic switching;
at least one axial propeller driven in rotation by the electric motor and constituting, together with the latter, an axial fan;
air an rectifiers;
an electronic board for tool management and motor control, said functional assembly being housed in the central or intermediary pan of said air-guide conduit with which it is in contact.

Abstract
A standalone portable electric blower has a propeller generating airflow and driven by an electric motor powered: by a power source, said blower including an air-guide conduit made up of a series of three generally cylindrical tubular portions, namely a proximal portion or suction nozzle provided with an air inlet, a distal air exit portion or exhaust nozzle and a central portion. The central portion is a separate piece and is arranged to form a functional assembly, unitary or made up of a plurality of elements and made of a heat conducting material, said central portion comprising the following functional sub-assemblies; an electronic switching electric motor; at least one axial, propeller rotated b the electric motor; air rectifiers; and an electronic board for managing the tool and controlling the motor. The functional assembly is housed in the central or intermediate portion of said air-guide conduit with which said assembly engages,
