Definitions

  • the present invention relates to the field of vacuum cleaners equipped with a vacuum cleaner nozzle, also called a suction head, making it possible to suck up dust and waste present on a surface to be cleaned, which can for example be tiles, parquet or parquet. laminate.
  • a vacuum cleaner nozzle according to the preamble of claim 1 is known for example from the document US-A-2012000033 .
  • the first and second scraping branches delimit at least in part a central passage opening which is fluidly connected to the suction channel so as to allow suction of waste through the central passage opening and towards the suction channel , and are configured to direct waste, coming into contact against the front scraping member during forward movement of the vacuum cleaner nozzle, towards the central passage opening.
  • the first and second extension directions are inclined relative to each other by an inclination angle of approximately 135°.
  • Such an angle of inclination makes it possible to channel large waste, coming into contact against the front scraping member during a forward movement of the vacuum cleaner nozzle, towards the central passage opening with a view to their suction , and also ensure rapid movement of this large waste towards the central passage opening.
  • a vacuum cleaner nozzle ensures rapid and efficient suction of large waste present on a surface to be cleaned.
  • such an angle of inclination of the first and second directions of extension has the disadvantage of giving the vacuum cleaner nozzle a large frontal bulk, such that it is not easy to vacuum, with such a vacuum cleaner nozzle, waste located for example along a wall or plinth.
  • the present invention aims to remedy these drawbacks.
  • the technical problem underlying the invention consists in particular of providing a vacuum cleaner nozzle which is simple and compact in structure, while allowing effective suction of dust and large waste, such as grains of rice or lentils, present on a surface to be cleaned.
  • the first and second directions of extension are inclined relative to each other by an angle of inclination of between 165° and 178°, and advantageously between 170 and 178°, and for example approximately 176° .
