Problems solved by technology

The mounting of the support sleeve on the control handle of the appliance at the opposite end of the blower head makes the work very difficult and laborious because of such a permanent effort, which should provide the operator with countering the tendency of said blower head to tip over towards the lower end , despite using the carrying strap
Furthermore, making the blower duct out of insulating material does not allow the heat generated by the operation of the motor or fan to dissipate

Embodiment Construction

[0071] Interesting but by no means limiting embodiments of an air blower device and a portable electric blower are described by way of application with reference to the accompanying drawings.

[0072] The blower shown consists essentially of an air guide duct 1 consisting of three consecutive integral cylindrical tubular parts, namely a proximal part or suction nozzle 2 provided with an air inlet 3, a distal air outlet A portion or exhaust jet 4 and a central or intermediate portion 5 arranged between said proximal and distal portions. In this central part is placed the functional assembly, designated 6 as a whole, integral or assembled from several elements and made of a material with good thermal conductivity, said functional assembly comprising the following functional sub-assemblies:

[0073] - an electronically commutated electric motor 7, usually called a brushless motor;

[0074] - at least one axial propeller 8 driven in rotation by the electric motor;

[0075] - air...

Abstract

The invention relates to a standalone portable electric blower, comprising at least one propeller (8) generating an 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, characterised in that the central portion is arranged such as to form a functional assembly (6), unitary or made up of a plurality of elements and made of a material that is a good heat conductor, said central portion comprising the following functional sub-assemblies: an electronic switching electric motor (7); at least one axial propeller (8) rotated by the electric motor; air rectifiers (9); and an electronic board (10) for managing the tool and controlling the motor, said functional assembly being housed in the central or intermediate portion of said air-guide conduit with which said assembly engages.

Description

technical field [0001] The present invention relates to a self-contained portable electric blower with adjustable air discharge velocity. It applies in particular to appliances of the type intended for sweeping and / or cleaning by blowing air over large surfaces such as lawns, city breezeways, outdoor car parks, sports or playgrounds and the like. The results obtained by using this equipment are similar to those achieved by using a traditional broom or tine rake, but the work is much easier and infinitely faster. In this application, the use of such a machine is to drive off debris strewn on the ground and partly arranged under obstacles such as cars in a parking lot, to form piles or piles which are then absorbed by the machine , sweeper or sweeper (brosseuse) collection. Such appliances are usually in the form of handheld portable devices and may be carried by a strap. In practice, they are used by continuously adapting the speed of the air stream to the conditions of the ...
