Document Type and Number:
WIPO Patent Application WO/2024/093216
Kind Code:
A1
Abstract:
A lifting/lowering apparatus (100) and a cleaning apparatus. The lifting/lowering apparatus (100) comprises a driving motor (1), a rotating shaft (2), a transmission assembly (3), and a traction member (4); the rotating shaft (2) comprises a mounting portion (21) and a lifting/lowering driving portion (22) that are connected, and the mounting portion (21) is used for being connected to a cleaning member (300); the transmission assembly (3) is separately connected to the output end of the driving motor (1) and the rotating shaft (2) so as to transmit the power of the driving motor (1) to the rotating shaft (2); the traction member (4) is in threaded connection with the lifting/lowering driving portion (22); when the rotating shaft (2) is driven by the driving motor (1) to rotate in a first rotating direction, the lifting/lowering driving portion (22) rotates relative to the traction member (4) and moves in a direction close to the mounting portion (21); when the rotating shaft (2) is driven by the driving motor (1) to rotate in a second rotating direction opposite to the first rotating direction, the lifting/lowering driving portion (22) rotates relative to the traction member (4) and moves in a direction away from the mounting portion (21). The present invention is conductive to reducing the size of a cleaning apparatus having a lifting/lowering function, thereby improving the practicability of the cleaning apparatus.
