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 as separate components and 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 elec...

Abstract

The present invention relates to a self-contained portable electric blower comprising at least one propeller (8) generating an air flow and driven by an electric motor powered by a mains, said blower comprising an air guide duct formed by a series of three integral columns shaped tubular part, i.e. a proximal part provided with an air inlet or suction nozzle, a distal air outlet part or exhaust nozzle and a central part, characterized in that the central part is arranged to form a functional assembly (6 ), which is monolithic or composed of multiple elements and made of a material with good thermal conductivity, said central part includes the following functional subassemblies: an electronic exchange electric motor (7); at least one motor driven in rotation by this electric motor an axial propeller (8); an air rectifier (9); an electronic circuit board (10) for managing the tool or controlling this motor, said functional assembly being housed in the center or middle part of said air guide duct and connected to the Air guide tube engaged.

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 ...
