Definitions

  • the present invention relates to the field of vacuum cleaners equipped with a suction nozzle, also called suction head, to suck dust and small-size waste present on a surface.
  • Vacuums equipped with a suction nozzle are well known on the market, they allow cleaning surfaces by suction for the evacuation of dust and small size waste based on them.
  • the surface to be vacuumed may for example be tiled, parquet, laminate, carpet or carpet.
  • a suction nozzle traditionally comprises a connecting sleeve and a sole provided with a lower face and at least one suction channel communicating with the connecting sleeve and opening on the underside of the sole.
  • the underside of the soleplate is intended to be positioned adjacent to the surface to be sucked during use of the vacuum nozzle.
  • a sole of the vacuum nozzle having a substantially triangular shape and provided with a main suction channel opening into the lower face and extending in a first direction of extension which is substantially transverse to a direction of movement of the nozzle nozzle; vacuum cleaner, and a secondary suction channel opening into the lower face and extending in a second extension direction which is substantially parallel to the direction of movement of the vacuum nozzle, the secondary suction channel being fluidically connected to the main suction channel.
  • part of the waste sucked by the suction nozzle follows the path formed by the main suction channel and is discharged through a suction pipe which is provided with the sole , while another part of the waste sucked by the suction nozzle follows the secondary suction channel before being evacuated also by the suction duct.
  • the presence of the main and secondary suction channels ensures that such a suction nozzle has improved suction capacity compared to triangular shaped nozzles without a secondary suction channel.
  • the suction efficiency of such a suction nozzle, and especially at the secondary suction channel, may sometimes be insufficient to ensure suction of large waste (of the order of a few grams) when the vacuum equipped with such a nozzle has relatively low suction rates.
  • the present invention aims to remedy all or part of these disadvantages.
  • the technical problem underlying the invention consists in particular in providing a sucker sucker structural reliable and economical, while ensuring improved suction performance.
  • the present invention relates to a vacuum nozzle comprising a sole having a substantially triangular shape and comprising first and second side edges forming a front tip of the vacuum nozzle, the sole being provided with a lower face, a main suction channel opening into the lower face and extending in a first direction of extension which is substantially transverse, and for example substantially perpendicular, to a direction of movement of the vacuum nozzle, and a channel secondary suction nozzle opening into the lower face and extending in a second direction of extension which is substantially parallel to the direction of movement of the vacuum nozzle, the secondary suction channel being fluidly connected to the suction channel; characterized in that the underside of the sole comprises a front portion extending from a front edge of the main suction channel to the vicinity of the front tip of the vacuum nozzle, and for example to the front tip of the vacuum nozzle, the front portion of the lower face being substantially flat and inclined so that when the sole is disposed on a surface to be cleaned, the front tip of the vacuum cleaner is closer to the surface to
  • Such a configuration of the front portion of the underside of the soleplate has the effect of reducing the passage section of the air flow at the front tip of the vacuum nozzle, and thus to increase the speeds of air flow at the front tip of the nozzle.
  • Such an increase in suction speeds at the tip of the nozzle enhances the suction of large waste via the secondary suction channel and the evacuation of this waste to the main suction channel.
  • the vacuum nozzle according to the present invention has an optimum suction efficiency, and thus improved suction performance.
  • the vacuum nozzle may further have one or more of the following features, taken alone or in combination.
