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.

First claim

What is claimed is:

1. 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.

2. The side brush of claim 1 , wherein the scraping part precedes the secondary scraping part in the rotational direction of the scraper.

3. The side brush of claim 1 , wherein an opening is provided between the first portion of the connecting part and the second portion of the connecting part.

4. The side brush of claim 1 , wherein the side brush comprises a plurality of scrapers, and the plurality of scrapers are evenly distributed along a circumference of the side brush base.

5. The side brush of claim 1 , wherein each scraper is formed through glue injection molding.

6. A smart cleaning device, comprising:
a device body;
a driving system connected to the device body and configured to drive the smart cleaning device across a floor surface;
a cleaning system configured to perform a cleaning operation, wherein:
the cleaning system comprises a side brush comprising:
a side brush base mounted to a bottom of the device body, and
one or more scrapers connected to a peripheral side of the side brush base and configured to engage the 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.

7. The smart cleaning device of claim 6 , wherein the side brush comprises a brush body base connected to the one or more scrapers and assembled to the side brush base.

8. The smart cleaning device of claim 7 , wherein the side brush base comprises a side brush base body, a boss to be assembled to the device body, and a receiving part between the side brush base body and the boss, where the brush body base is accommodated in the receiving part.

9. The smart cleaning device of claim 8 , wherein the side brush base body comprises one or more side brush base openings, each side brush base opening is configured to be penetrated by a respective scraper, and each scraper comprises a brush body mounting part adapted in shape to a respective side brush base opening.

10. The smart cleaning device of claim 6 , wherein the scraping part precedes the secondary scraping part in the rotational direction of the scraper.

11. The side brush of claim 1 , wherein the side brush comprises a brush body mounting part connected to the side brush base, and the connecting part of each scraper is connected to the side brush base through the brush body mounting part.

12. The side brush of claim 11 , wherein the connecting part of each scraper is integrally formed with the brush body mounting part.

13. The smart cleaning device of claim 6 , wherein the side brush comprises a brush body mounting part connected to the side brush base, and the connecting part of each scraper is connected to the side brush base through the brush body mounting part.

14. The smart cleaning device of claim 13 , wherein the connecting part of each scraper is integrally formed with the brush body mounting part.
