SURFACE CLEANER NOZZLE DEVICE Russian patent published in 2018 - IPC A47L11/40 

FIELD: personal use and household items.

SUBSTANCE: nozzle device (10) of the surface cleaner (100) (20) is proposed that comprises the casing (28) of the nozzle; the rotating brush (12), which comprises the cylindrical central element (52) with the flexible brush elements (16) that are located on the circumferential surface (56) of the central element (52). Brush elements (16) are arranged in order allow to contact with the surface (20) to be cleaned and picking up particles (22, 24) of liquid and dirt from the surface to be cleaned (20) during rotation of the rotating brush (12). Nozzle device comprises the drive for driving the rotating brush (12), the device (58) for supplying the cleaning liquid (68) to the rotary brush (12), the scraping member (32) for wiping the particles (22, 24) of liquid and dirt along the cleaning surface (20) or from this surface. Scraper element (32) extends in the longitudinal direction (48) parallel to the brush axis (14) and is situated on the first longitudinal side (27) of the rotating brush (12), on which the brush elements (16) enter the casing (28) of the nozzle as the rotating brush (12) rotates. Nozzle device comprises at least one lateral sealing element (62a, b) for sealing the side (82a, b) of the nozzle casing (28), where at least one lateral sealing element (62a, b) is spaced from the transverse side (80a, b) of the central element (52), which is the transverse circumferential surface (56) of the central element (52), so as to form the gap (84a, b) between the mentioned transverse side (80a, b) of the central element (52) and at least one lateral sealing element (62a, b). Liquid supply device (58) is configured in order to supply the cleaning fluid (68) also to the mentioned gap (84a, b).

EFFECT: surface cleaner nozzle device is proposed.
