Vacuum cleaner nozzle with turbine-driven roller brush

摘要

The nozzle has a union for the hose and a roller brush driven by a turbine in the housing. The turbine is embraced by a linkage pivoting about the turbine axis. The housing has flow channels opening out into a central one where the turbine is, past which the suction air flows. The turbine is made up of several modules plugged together. The modules are separate chambers with blades on the outer periphery of the side walls, joined by complementary connectors. At least two modules use one connector. In the middle of the side walls are other connectors for the axles of the modules. The turbine blades are also joined to the blades of adjacent modules by connectors.
