Abstract

A suction nozzle (otherwise called “brush”) for sucking up dust and/or fluids and/or waste from a surface is described. The suction nozzle comprises a base plate with at least one channel open towards said surface, a suction duct in fluid communication with the at least one channel of the base plate and a body associated with said base plate. According to the invention, the suction duct is produced as a component separate from the plate and the body. Connection means are also provided for connecting the suction duct to the body and/or to the base plate. Owing to the present invention, more efficient suction ducts which produce less noise than the known ducts may be produced.

Claims

1. Suction nozzle for sucking up dust and/or fluids and/or waste from a surface, said suction nozzle comprising a base plate With at least one channel open towards said surface, a suction duct in fluid communication with the at least one channel of the base plate, characterized in that said suction duct is produced as a component separate from said plate and from a suction nozzle body and in that it comprises connection means for connecting said suction duct to at least either one of said body and said base plate.

2. Suction nozzle according to claim 1, characterized in that said connection means comprise a mechanical snap-engaging system.

3. Suction nozzle according to claim 1, characterized in that said connection means comprise a screw-type or similar fixing system.

4. Suction nozzle according to claim 1, characterized in that said connection means comprise a substantially inseparable fixing system, realized by means of adhesive, hot-plate bonding or ultrasound.

5. Suction nozzle according to claim 1, characterized in that said connection means comprise a combination of two or more of the following systems:

mechanical snap-engaging system, screw-type or similar fixing system and fixing system realized by means of adhesive, hot-plate bonding or ultrasound.

6. Suction nozzle according to any one of the claim 1, characterized in that said suction duct is fixed to said base plate substantially at its end which is in fluid communication with the at least one base plate channel.

7. Suction nozzle according to any one of the claim 1, characterized in that said suction duct and said base plate comprise positioning/engaging members for correctly joining together suction duct and base plate.

8. Suction nozzle according to claim 7, characterized in that said positioning/engaging members comprise at least one pin projecting from said base plate and said suction duct comprises at least one corresponding cavity complementing said at least one pin.
