Cleaning equipment Cross-reference of related applications This disclosure claims priority to Chinese patent application No. 202422685297.1, filed on November 4, 2024, the entire contents of which are incorporated herein by reference. Technical Field This disclosure relates to the field of cleaning technology, and more specifically, to a cleaning device. Background Technology During the cleaning process, cleaning robots or cleaning equipment such as robot vacuums and robot mops are prone to having debris such as hair and fibers entangled on cleaning components such as roller brushes. These debris are not easily sucked into the dust collection components, which affects the cleaning effect. The cleaning components need to be cleaned and replaced frequently and are difficult to clean. Summary of the Invention This disclosure aims to at least partially address one of the technical problems in the related art. Embodiments of this disclosure provide a cleaning device. The cleaning device of this disclosure includes: a body having a receiving cavity; a cleaning component rotatably disposed within the receiving cavity about its central axis, the cleaning component having a cleaning element; and a comb component including a mounting plate and a plurality of comb teeth for cleaning the cleaning element, the mounting plate being detachably mounted on the wall of the receiving cavity, the plurality of comb teeth being disposed on the mounting plate and arranged along the axial direction of the cleaning component, the included angle between the comb teeth and the axial direction of the cleaning component being greater than or equal to 65 degrees and less than or equal to 85 degrees. In the cleaning device of this embodiment, the comb teeth are detachably mounted on the wall of the receiving cavity, facilitating disassembly, maintenance, and replacement. Simultaneously, the included angle between the comb teeth and the cleaning component's axial direction is greater than or equal to 65 degrees and less than or equal to 85 degrees. This improves the cleaning effect of the comb teeth on debris entangled on the cleaning component. If the included angle between the comb teeth and the cleaning component's axial direction is less than 65 degrees, the resistance from the comb teeth to the cleaning component is greater, affecting the rotation of the cleaning component, increasing energy consumption, and causing damage to the cleaning component. If the included angle between the comb teeth and the cleaning component's axial direction is greater than 85 degrees, the cleaning component can easily pass through the gaps between adjacent comb teeth when passing over them, affecting the cleaning effect of the comb teeth on the cleaning component.

In some embodiments, the mounting plate is snapped into the mounting groove by a snap-fit structure. In some embodiments, the comb teeth and the mounting plate are integrally injection molded. In some embodiments, the mounting plate has a first side and a second side extending axially along the cleaning component, and the comb teeth have a first tooth tip and a second tooth tip, the first tooth tip of the comb teeth being adjacent to the first side of the mounting plate, and the second tooth tip of the comb teeth being away from the first side of the mounting plate. The end face of the first tooth of the comb is flush with the first side of the mounting plate, or the end face of the first tooth of at least one comb extends outward beyond the first side of the mounting plate. In some embodiments, the accommodating cavity has a dust collection port, the mounting plate is disposed adjacent to the dust collection port, a first side of the mounting plate is adjacent to the dust collection port, a second side of the mounting plate is away from the dust collection port, a first tooth tip of the comb is adjacent to the first side of the mounting plate, a second tooth tip of the comb is away from the first side of the mounting plate, in the axial direction of the cleaning component, the outermost comb tooth is adjacent to the first end of the dust collection port, the other outermost comb tooth is adjacent to the second end of the dust collection port, and/or, the distance between the first side of the mounting plate and the side of the dust collection port adjacent to the mounting plate is greater than zero and less than or equal to 10 mm.
