Definitions

  • the present invention relates to the field of vacuum cleaners and relates particularly to the design of the vacuum nozzle, also called suction head or suction head, which are sucked dust.
  • the invention aims to design a suction nozzle which ensures optimal suction over the entire surface to be sucked, despite the possible presence of obstacles.
  • vacuum cleaners trolley type vacuum or brush type vacuum comprises a nozzle consisting of a head having either a rectangular shape or a triangular shape.
  • suckers with rectangular head can effectively dust all types of surfaces, such as carpets, carpets, smooth floors, floors or other, the most difficult to achieve performance on carpets.
  • the arrival of energy labels in the field of vacuum cleaners has led manufacturers to reduce the power of the vacuum cleaner motors and thus the air flow sucked in and to develop rectangular suckers maintaining maximum suction performance with a lower suction airflow.
  • suckers rectangular head It would therefore be ideal to equip each vacuum cleaner with two suckers, one consisting of a rectangular head and the other consisting of a triangular head, in order to have optimal performance in all circumstances (clear surfaces or in the presence of obstacles such as a corner of a room, a plinth or furniture).
  • the nozzle consists of a suction head having two rectangular side elements adapted to fold for suction in the corners of rooms.
  • the present invention aims to design a nozzle to overcome the aforementioned drawbacks.
  • the invention relates to a vacuum nozzle designed to be moved on a surface to be sucked.
  • the nozzle comprises a first, preferably rectangular head, which comprises a first suction pipe connected to a first suction mouth arranged on a lower face of said first head.
  • the nozzle comprises a second head, preferably triangular, which extends forwardly the first head.
  • the second head comprises a second suction duct connected to a second suction mouth arranged on a lower face of said second head.
  • the nozzle comprises distributing means for modifying the distribution of the suction between the first suction mouth and the second suction mouth.
  • Such a characteristic makes it possible to have a nozzle whose suction performance and ergonomics of use can be strongly modified by modifying the distribution of suction between the two heads. It is thus possible to obtain a nozzle whose suction performance approaches that of the first head used alone, the second head used alone or a mix of the two heads.
  • the nozzle can combine both the performance of the first head, which has been the subject of in-depth studies and whose suction performance has been optimized to successfully pass the various performance tests, and those of a second head to provide additional functionality such as dusting in difficult to access area.
  • the nozzle according to the invention has the advantage of being partly constituted by a first head, which can be standard and marketed in large quantities without being associated with the second head, and a second more specific head which allows to differentiate the nozzle according to the invention of the nozzle constituted by the single first head.
  • a first head which can be standard and marketed in large quantities without being associated with the second head
  • a second more specific head which allows to differentiate the nozzle according to the invention of the nozzle constituted by the single first head.
  • the distribution means can occupy a first position in which they allow suction only by the first suction mouth and at least a second position in which they allow aspiration at least by the second suction mouth .
  • Such a nozzle has the advantage of being able to be used with a position of the distributor means in which the suction takes place only through the first head, making it possible to obtain suction performance similar to the nozzle usually only constituted by the first head.
  • the distribution means in the second position, can occupy a position in which they allow suction only by the second suction mouth.
  • the second head comprises an obstacle detection device and the distribution means are automatically moved to the second position when the detection device detects an obstacle.
  • Such a characteristic makes it possible to favor suction as close as possible to the obstacle when the nozzle meets an obstacle such as a skirting board.
  • the first head has a trapezoidal shape, preferably rectangular.
  • Such a characteristic makes it possible to have a nozzle having a first head of usual shape and construction, the performances of which have been tested on other suckers.
  • the second head has a width in width smaller than the first head.
  • Such a characteristic makes it possible to obtain a nozzle having both a first head having a width sufficient to ensure dust suction over a large width and a second head, arranged in front of the first head, having a smaller width to suck more easily in the corners of the rooms or in the recesses.
  • the second head has a shape converging towards a front end of reduced width, the second head advantageously having a triangular shape.
  • Such a feature can further optimize the ability of the nozzle to suck in the corners.
  • the first head ensures suction of the surface, the suction by the second head being condemned.
  • the nozzle meets an obstacle, for example a room angle, a plinth along a wall or furniture, or only the second head ensures suction of the surface, the suction by the first head being condemned, either to both the first head and the second head provide suction.
  • the second head is triangular and the stop means comprise two stop bars arranged respectively along the two sides forming the tip of the triangular head.
  • the two stop bars are mounted pivotally connected to each other at the tip of the triangular head.
  • Other abutment means remain possible within the scope of the invention.

  • sealing means are implemented between the shutter and the orifice to ensure a tight closure of said orifice. This seal optimizes suction performance by the first head.
  • At least a portion of the intermediate conduit is flexible so as to allow freedom of movement between the first head and the second head. This freedom of movement allows the first head to work freely and correctly during the suction of an unobstructed surface, without interference of the second head.
  • the shutter is constituted by a valve mounted in pivot connection, said valve being configured to pivot in a closed position of the orifice or in an open position of the orifice, said valve being configured to close the first suction mouth in its open position of the orifice.
  • said sealing means are configured to ensure a seal between the valve and the first suction mouth in the open position of said valve.
  • the transmission means comprise at least one arm extending forwards the valve and at least one lever mounted in pivot connection and arranged between the at least one arm and the stop means, activation of the abutment means in contact with an obstacle causing the pivoting of the valve in the open position of the orifice.

  • the first nozzle head according to the invention can comprise all the advantageous functions of the suckers, in particular with a rectangular head, which currently exist, such as the functions making it possible to perform angular wedging of the head, for example to scrape the surface while by aspiring him.
  • the latter comprises at least one connecting rod whose two ends are mounted in pivot connection respectively on the first head and the second head.
  • the articulation system comprises two connecting rods.
  • the second head comprises a ground clearance greater than that of the first head. This makes it possible to maintain all the efficiency of the dust collection, in particular during carpet-type surface suction; this greater ground clearance for the second head, disposed in front of the first head, ensures in fact that the underside of said second head does not touch the surface, especially in the case of carpets, which would have the effect of retaining the dust on the surface during suction by the first head.
