Description

(Related applications) This disclosure claims priority to Chinese patent applications No. 202211734557.9, 202211739051.7, 202211739794.4, 202211740301.9, and 202211736856.6, filed on December 30, 2022, all of which are incorporated herein by reference as part of this disclosure. This disclosure relates to the technical field of cleaning devices, and more specifically, to automatic cleaning devices. With the continuous advancement of technology, automatic cleaning devices such as sweeping robots and sweeping mops have become widespread in ordinary households. Sweeping robots achieve their sweeping function by using cleaning brushes to pick up debris of different sizes from the floor surface and then using suction to send it to a waste collection bin. The structure and installation method of the cleaning brush are crucial factors influencing the cleaning effectiveness of automatic cleaning devices. However, existing single-brush structures fail to improve the cleaning effectiveness of automatic cleaning devices and cannot perform targeted cleaning on different surfaces, thus limiting the wide range of applications for automatic cleaning devices. Embodiments of this disclosure provide an automatic cleaning device comprising a first roller brush and a second roller brush, wherein the first roller brush comprises a first shaft member and a first brush member, the first shaft member having a support surface that contacts and supports the first brush member, and at least a portion of the support surface of the first shaft member is incompressible, and/or, the second roller brush comprises a second shaft member and a second brush member, the second shaft member having a support surface that contacts and supports the second brush member, and at least a portion of the support surface of the second shaft member is incompressible. In some embodiments, the support surfaces of the first axial member are entirely non-compressible, and/or the support surfaces of the second axial member are entirely non-compressible.

In some embodiments, all surfaces on which the first shaft member supports the first cylindrical member are incompressible, and/or all surfaces on which the second shaft member supports the second cylindrical member are incompressible. In some embodiments, the support surface at the axial end of the first shaft member is compressible, while the remaining portion is not compressible, and/or the support surface at the axial end of the second shaft member is compressible, while the remaining portion is not compressible. In some embodiments, the support surface of the first shaft member at its axial center is compressible, while the remaining portion is not compressible, and/or the support surface of the second shaft member at its axial center is compressible, while the remaining portion is not compressible.
