Definitions

• the present invention relates to a vacuum cleaner device, designed for suction of air and liquid on a flat surface, and more particularly active part of said vacuum device, intended to be moved on said surface.
• the present invention more particularly relates to the field of flat surface cleaning squeegees such as glazed surfaces, using suction to remove residual cleaning water.
• the present invention is however not limited to this use and can very well be applied to the cleaning of other surfaces than glass surfaces.
• the active part of the vacuum cleaner device according to the invention can be associated on said device with additional means for treating the surface to be cleaned, whether it be cleaning means such as a wipe, for example, and / or means for spraying cleaning liquid or steam.
• These squeegees generally comprise a flexible scraping blade, associated with an active suction means at the lower edge of said blade.
• Such cleaning devices are already known, and in particular those described in WO2010018312 for example, or the document WO2009086891.
• the suction can be carried out in different ways, for example between two blades forming a suction mouth, or through a textile cloth disposed under a scraper blade and in which is collected the residual water.
• the scraping operation is to move the squeegee on the flat surface in a succession of more or less rectilinear movements, preferably from top to bottom when said surface is vertical.
• the user is still faced with the same problem the subsistence of a mark of residual water at the end of the path of the squeegee. This is mainly due to the fact that the angle formed by the scraping blade with the flat surface is not constant but increases, and that therefore the mouth through which the suction is carried out is not of optimal shape.
• the two blades B and C deform and get closer which restricts the suction capabilities, and which requires creating on the edge of the blade that enters in contact first with the residual liquid, notches, not shown, allowing the passage of said liquid.
• Scrapers are also known which comprise a single blade pierced with channels which open out behind the scraping edge, and which are intended for the evacuation of water under the effect of a depression.
• a scraper is described in EP 0 422 977, where the channels are extended by pipes.
• the disadvantage of this type of squeegee besides the fact that the channels can easily become clogged, is that by capillary effect, the water tends to cling to the walls of the channels, so as to require a strong depression, and therefore a greater motorization with all the consequences related to that , ie higher consumption, higher weight etc ...
• the present invention aims to overcome the aforementioned various drawbacks, by providing a vacuum cleaner device for cleaning a flat surface leaving as few traces as possible, regardless of the direction in which the movement is given.
• the vacuum cleaner device designed adapted to the suction of air and liquid on a flat surface, and more particularly the active part of scraper blade type intended to be displaced on said surface, is characterized by that said active part is in the form of a single blade, made of a flexible or semi-rigid material, intended to be moved in a direction against said flat surface, and which has an internal cavity connected to a means for producing said suction of air and liquid, and delimited, at the distal portion of said blade, behind the edge intended to be displaced on said surface, by two walls forming an angle between them and which meet at the of said ridge, the wall intended to be presented first to said surface to be scraped during a scraping operation, having, along and near said ridge, a multiplicity of holes which open into said cavity.
• the present invention also relates to a vacuum cleaner device, according to the invention, designed for suction of air and liquid on a flat surface, and more particularly the active part of scraper blade type to be moved.

• the scraping blade-type active part comprises, on each of the two blades or walls, on either side and close to the edge, a multiplicity of holes which lead into the cavity.
• Such a variant allows and scrape and suck when scraping performed in both directions of movement of the active part on the surface to be scraped.
• the scraper blade has no channels or tubes likely to clog or limit the suction capabilities.
• the holes each have an outer chamfer.
• the cavity is provided with reinforcing means which extend between the two walls or blades, ensuring its non-crushing.

• each of the non-return means consists of a frustoconical channel allowing the communication between a hole of the multiplicity of holes, and the internal cavity connected to the means for producing the suction of air and liquid.
