Abstract
This application discloses a side brush and a smart cleaning device. The side brush includes a side brush base for mounting to a smart cleaning device and a scraper connected to a peripheral side of the side brush base. The scraper is configured to be in contact with the floor, so as to scrape sundries. A structure of the side brush can effectively prevent the side brush from being entangled with sundries during cleaning.

A side brush, comprising:
- a side brush base, configured to be mounted to a smart cleaning device;
- and
- one or more scrapers, connected to a peripheral side of the side brush base and configured to engage a floor surface to remove debris,
- wherein each scraper comprises a connecting part connected to the side brush base, and a scraping part connected to a first portion of the connecting part and configured to extend from the first portion of the connecting part to the floor surface;
- wherein each scraper is configured to rotate about an axis to remove the debris, where the axis is configured to be generally perpendicular to the floor surface;
- wherein the scraping part comprises a front surface and a rear surface in a rotational direction of the scraper, and the front surface is configured to tilt at an angle relative to the floor surface;
- wherein the front surface comprises a first end configured to make contact with the floor surface and a second end connected to the connecting part, where the first end precedes the second end in the rotational direction of the scraper;
- wherein each scraper further comprises a secondary scraping part connected to a second portion of the connecting part and configured to extend from the second portion of the connecting part to the floor surface, where the secondary scraping part is configured to be disposed vertically relative to the floor surface, and
- wherein the second portion of the connecting part is parallel to the first portion of the connecting part.
