WIPO Patent Application WO/2024/050691
Kind Code:
A1
Abstract:
A floor brush (100) of a floor cleaning device, comprising a housing (1) and a roller cavity (2) formed by the housing (1). A suction channel (3) communicated with the roller cavity (2) is formed in the housing (1); a self-rolling roller (4) is mounted in the roller cavity (2); a bottom opening (21) communicated with the roller cavity (2) is provided at the bottom of the housing (1); the roller (4) is in contact with a cleaning surface through the bottom opening (21); sealing rubber strips (5) are arranged on the peripheral edges of the bottom opening (21), the sealing rubber strip (5) located at the front side is divided into multiple sections, and the end of each section of the sealing rubber strip (5) can be deformed to be opened to form a dust suction inlet. When the floor is cleaned, the sealing rubber strips (5) are attached to the floor to enhance the suction force of the bottom opening (21) to the floor, and garbage and dust in front of the floor brush (100) are suctioned, by using the dust suction inlet on the front side, into a closed space formed by the bottom opening (21) so as to prevent the garbage and dust from being popped out by the roller (4) rotating at a high speed, and are then suctioned and recycled through the suction channel (3), thereby effectively collecting, cleaning, and suctioning away the garbage, and improving the floor cleaning effect. Moreover, the self-rolling roller (4) can be used for providing power for driving the floor brush (100) to walk, so that a user can use the floor brush more easily.
