Definitions

  • the present invention concerns a multi-functional electric brush, able to be used to suck in solid dry- particles of dust and dirt, and also liquid substances and damp materials.
  • An electric brush for cleaning comprising a supporting structure on which a suction unit is assembled provided with an electric motor and able to create a suction flow.
  • a cleaning end-piece is able to be connected to the supporting structure by means of a tubular connector, and is provided with a suction aperture disposed in correspondence with the surface to be cleaned, or is able to be extended as far as the latter.
  • the cleaning end-piece comprises, for example, a device with rotary brushes and driven by an electric motor, or a device to deliver a cleaning liquid.
  • WO-A-97/29675 describes an electric brush provided with a cleaning end-piece having an aperture for delivering a liquid and an aperture for sucking in said liquid.
  • a tank for the liquid is mounted on the supporting structure and is connected to the delivery aperture by means of a tube.
  • This known electric brush has the disadvantage that it is difficult to move and maneuver, because its baricenter is very high with respect to the floor, due to the raised position of the tank. Moreover, it does not comprise means to generate steam for cleaning and/or making the surface hygienic.
  • EP-A-0621003 describes an electric brush having a cleaning end-piece able to be associated with the supporting structure and provided with an electric motor in order to make the brushes rotate.
  • the electric brush of a known type also comprises a container associated with the suction unit and in which the material sucked in is collected.
  • This container is provided with a filter which can be of the dry type, or the water type, to contain possible liquids sucked in.
  • dry filters and water filters are not interchangeable, due to their different sizes, so that it is not possible to assemble them selectively and alternately in the same electric brush. This is therefore another disadvantage of known electric brushes.
  • One purpose of the present invention is to achieve a multi-functional electric brush in which the cleaning end- piece is connectable, simply and quickly, by means of a single operation, to the end of the supporting structure, guaranteeing both the mechanical assembly for conveying the material sucked in, and also the electric connection.
  • Another purpose of the present invention is to achieve a multi-functional electric brush which allows to deliver steam and/or cleaning liquids and which can be used, moved and maneuvered easily.
  • Another purpose of the present invention is to achieve a multi-functional electric brush in which the container for the material sucked in, either dry or containing water, can easily be replaced and is interchangeable with another that may not be of the same type.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • a multi-functional electric brush comprises a supporting structure, a suction unit fed electrically and able to create a suction flow, means to contain the material sucked in from the surface to be cleaned and at least a cleaning end-piece having at least a suction aperture.
  • the supporting structure is provided, at a lower end, with first connection means able to be coupled mechanically and removably with second connection means disposed on the cleaning end-piece in order to put the suction aperture in communication with the suction unit.
  • the cleaning end-piece comprises at least an electric device which is able to generate steam and/or deliver cleaning liquids, including hot or cold water.
  • the first and the second connection means comprise respectively first and second electric feed means able to feed the electric device electrically.
  • the cleaning end-piece can be connected to or removed from the end of the supporting structure, simply and quickly by means of a single operation, guaranteeing both the mechanical assembly for conveying the material sucked in by the suction aperture to the suction unit, and also the electric connection.
  • the electric device is integrated into the cleaning end-piece, allowing to displace the baricenter of the electric brush downwards, thus making it more easily usable, movable and maneuverable with respect to known solutions.
  • the cleaning end-piece comprises at least an electric cleaning device having one or more brushes driven by an electric motor.
  • the first connection means comprise a first tubular suction pipe, not necessarily cylindrical, communicating at one end with said containing means, and terminating at another end with a first coupling element.
  • the second connection means comprise a second tubular suction pipe, also not necessarily cylindrical, communicating at one end with the suction aperture and terminating at another end with a second coupling element. Said two tubular pipes are able to be coupled in correspondence with the respective coupling elements, so as to achieve the mechanical connection between the supporting structure and the cleaning end-piece, and at the same time to guarantee continuity to the suction flow.
  • the first electric feed means are disposed adjacent to the first tubular suction pipe, while the second electric feed means are disposed adjacent to the second tubular suction pipe.
  • the first electric feed means are connected to an electric cable, for example arriving from the supporting structure, while the second electric feed means are connected to a feed cable that terminates in the cleaning end-piece in order to feed at least the electric device electrically.
  • the containing means comprise a liquid bath filter, towards which the dirt sucked in is conveyed and remains trapped, or alternatively a dry filter consisting for example of a bag made of paper or similar material, and able to block and contain the particles of dirt sucked in.
