Description
Technical Field
The present invention relates to the field of vacuum cleaners equipped with a cleaning head, also called vacuum cleaner nozzle, which allows to suck in dust and small-sized waste present on a surface.
Background
Vacuum cleaners equipped with a cleaning head are well known in the market which allow cleaning of surfaces by suction to evacuate dust and small particle size waste that remains on the surface. The surface to be cleaned may be, for example, a tile floor, a laminate, a carpet or a carpet.
The cleaning head conventionally comprises a connecting sleeve and a housing equipped with a lower surface positioned in an adjacent manner on a surface to be cleaned and a suction chamber communicating with the connecting sleeve, the suction chamber comprising a suction opening which opens onto the lower surface of the housing and accommodates a rotating brush located opposite the suction opening.
In order to improve in particular the dust removal efficiency of such cleaning heads on the carpet, it is known to provide a system for driving the rotation of the rotating brush inside the rotating brush. In fact, this configuration of the cleaning head allows to dispense with the presence of a belt and pinion, so as to couple the rotation of the drive motor and of the rotating brush.
However, mounting a cleaning head equipped with such a rotary drive system can be complex and cumbersome, since such arrangement of the rotary drive system requires the presence of a first rolling bearing and a second rolling bearing, respectively, provided at each end of the rotary brush to ensure proper positioning and centering of the rotary brush relative to the drive motor.
Disclosure of Invention
The present invention aims to overcome all or part of these disadvantages.
The object underlying the invention is in particular to provide a cleaning head which is structurally reliable and economical, while ensuring improved suction performance and easy installation of the cleaning head.
To this end, the invention relates to a cleaner head for a vacuum cleaner, comprising: a housing, a drive motor, a reducer rotatably coupled to the drive motor, and a rotating brush configured to be driven in rotation by the drive motor through the reducer, the rotating brush being removably mounted in the housing of the cleaning head, characterized in that the reducer is housed in the rotating brush and is fixed to the rotating brush such that the reducer remains integral with the rotating brush when the rotating brush is removed from the housing of the cleaning head.
This configuration of the cleaning head allows to divide the drive motor and the reducer into two separate parts, which allows to greatly simplify the mounting of the cleaning head, since it is possible to dispense with the presence of a rolling bearing at the end of the rotating brush located on one side of the drive motor. In fact, the positioning and centering of the rotating brush with respect to the drive motor can be ensured, for example, on the one hand by a rolling bearing located at the end of the rotating brush opposite the drive motor and, on the other hand, directly by the reducer. Thus, the speed reducer enables the rotating brush to be centered in an offset manner with respect to the drive motor.
Thus, the cleaning head according to the present invention allows the rotating brush to be centered with respect to the driving motor using a single rolling bearing, which reduces the weight of the cleaning head and shortens the installation time of the cleaning head.
