Suction device designed for air and liquid suction on a flat surface and a scraper blade for such a device

摘要

Suction device designed for air and liquid suction on a flat surface, more particularly a scraper blade type active part (1) for moving on said surface (S). The active part (1) is formed of a flexible or semi-rigid material and takes the form of a single blade for movement in one direction relative to a flat surface, said blade being for air and liquid suction An internal cavity connected to the implementation means, the internal cavity being located at the end of the blade (1), behind the ridge (21) for moving on the surface (S), and two septa (24, 30), the two partition walls form an angle between them and meet at the position of the ridge (21), in the direction of the surface to be scraped during the scraping operation The initially present partition (24) comprises a number of holes (23) leading to the cavity along and in the vicinity of the ridge (21).
