Ground suction nozzle for suction equipment for cleaning and caring for floor surface

The invention relates to a ground suction nozzle (1) for suction equipment, in particular a vacuum cleaner, for cleaning a floor surface, which comprises a suction opening (2) having at least one suction opening edge (3) arranged on the floor side, and an air supply device (5) for supplying air to the ground suction nozzle (1), wherein the suction opening edge at least partially encloses and delimits the suction opening (4), in the operating state of the ground suction nozzle (1), the air supply device (5) is fluidically connected to the suction opening (2) via the suction opening (4), so thatthe supplied air flows from at least one outlet (7) of the air supply device (5) under the at least one suction opening edge (3) into the suction opening (4). 本发明涉及一种用于清洁地面表面的抽吸设备、特别是吸尘器的接地吸嘴(1)，包括：具有设置在地面侧的至少一个抽吸口边棱(3)的抽吸口(2)，该抽吸口边棱至少部分地包围界定抽吸开口(4)，用于为接地吸嘴(1)输入补加空气的补加空气装置(5)，其中，在接地吸嘴(1)的运行状态中，补加空气装置(5)通过抽吸开口(4)与抽吸口(2)流体连接，使得补加空气从补加空气装置(5)的至少一个出口(7)在至少一个抽吸口边棱(3)之下流入抽吸开口(4)。
