Document Type and Number:
WIPO Patent Application WO/2023/040944
Kind Code:
A1
Abstract:
A cutting apparatus (100), a cleaning device (200), a cleaning base station (300), and a cleaning system and method. The cutting apparatus (100) comprises a housing (11), N sets of blades and a driving mechanism, and the housing (11) is provided with an opening (110). Each set of blades comprises one fixed blade (12) and one movable blade (13); N fixed blades (12) are located within the housing (11) and are arranged in a straight line; N movable blades (13) are located within the housing (11) and are arranged in a straight line; each movable blade (13) is correspondingly arranged with one fixed blade (12); the fixed blades (12) and the movable blades (13) each have a toothed edge portion (14), and the toothed edge portions (14) protrude from the opening (110) toward the outer side of the housing (11); the toothed edge portions (14) of the fixed blades (12) are closely fitted to the toothed edge portions (14) of the movable blades (13); and the driving mechanism linkingly cooperates with the movable blades (13) to drive the movable blades (13) to reciprocate between a first position and a second position relative to the fixed blades (12), and the movement directions of at least two movable blades (13) are opposite to one another. Thus, the straightness and degree of fitting between the movable blades (13) and the fixed blades (12) are ensured, and the movement directions of two adjacent movable blades (13) are opposite to one another, which may offset the inertial force and reduce system vibration.
