In the above embodiment, the first elastic member 701 is used to provide a force that enables the movable cover 302 to move relative to the rolling brush 200, so that the movable cover 302 can be always pressed against the surface of the rolling brush 200, and the rotating rolling brush 200 is always in contact with the inner side of the movable cover 302 during the operation of the cleaning device, so that the cleaning of the movable cover 302 is achieved through the friction action of the rolling brush 200.
The specific form of the first elastic member 701 is not specifically limited in this embodiment, and any elastic member capable of achieving the above functions may be used, for example, specific forms of the first elastic member 701 include, but are not limited to, torsion springs, compression springs, tension springs, leaf springs, etc., but from the viewpoints of structural simplicity and energy consumption, the first elastic member 701 is preferably a coil spring. The number of the first elastic members 701 may be one or more, for example, the first elastic members 701 may be selected to be coil springs, and two first elastic members are disposed along the axial direction of the rolling brush 200, and the elastic force of each coil spring is preferably 10-15N, so as to avoid that the cleaning effect cannot be achieved due to too low elastic force of the coil springs, and avoid that the current of the driving motor is influenced due to too high elastic force of the coil springs, thereby influencing the duration of the whole machine.
In some embodiments, the rolling brush cover assembly 300 further includes a fixed cover plate 303 connected to or integrally formed with the base 301, the fixed cover plate 303 is disposed on a side of the movable cover plate 302 facing away from the rolling brush 200, a gap 304 is formed between the fixed cover plate 303 and the movable cover plate 302, the first elastic member 701 is disposed in the gap 304, and two ends of the first elastic member 701 are respectively connected to the fixed cover plate 303 and the movable cover plate 302. On the one hand, the fixed cover 303 can be used for protecting the movable cover 302 which is arranged movably; on the other hand, the fixed cover 303 may serve as a carrier to which the first elastic member 701 is attached; furthermore, the gap 304 formed between the fixed cover plate 303 and the movable cover plate 302 provides room for movement of the movable cover plate 302 to the second position.
