Title:
FLOOR BRUSH ASSEMBLY FOR CLEANING DEVICE, CLEANING DEVICE, AND VACUUM CLEANER
Document Type and Number:
WIPO Patent Application WO/2021/253669
Kind Code:
A1
Abstract:
A floor brush assembly (10) for a cleaning device (1) may be connected to a body unit (20) of the cleaning device (1). A first positioning part (201) is arranged on the back of the body unit (20). A plurality of first limiting parts (202) are arranged at the bottom of the body unit. The floor brush assembly (10) comprises a floor brush housing (11) and a connecting member (15). The connecting member (15) is pivotably connected to the floor brush housing (11). The connecting member (15) is provided with a second positioning part (153) and a plurality of second limiting parts (154). When the body assembly (20) is connected to the floor brush assembly (10), the second positioning part (153) engages the first positioning part (201), and the plurality of second limiting parts (154) respectively engage with the plurality of first limiting parts (202) on the basis of a one-to-one correspondence. When the body unit (20) is turned relative to the floor brush housing (11), the second positioning part (153) and the plurality of second limiting parts (154) simultaneously act on the body unit (20). By providing a plurality of second limiting parts (154), and by allowing the second positioning part (153) and the plurality of second limiting parts (154) to simultaneously act on the body unit (20), both may absorb the torque generated when the body unit (20) is turned.
