Sweeping and Suction Device, Dust-collecting Box Thereof, and Cleaning Robot Using the Same

Abstract

The present invention discloses a sweeping and suction device and a dust-collecting box thereof and a cleaning robot using the same, wherein the cleaning robot comprises the dust-collecting box connecting with the sweeping and suction device; when the cleaning robot is operating and moving, protruding tube bodies of the sweeping and suction device sweep the surface to be cleaned to push the dust and dirt away from the surface to be cleaned; then the cleaning robot guides the outside air to flow from the protruding tube bodies into the dust-collecting box, thereby allowing to remove the dust and dirt easily from the surface to be cleaned and to transfer the dust and dirt to the dust-collecting box by using the sweeping and suction device to reach into and to sweep the surface to be cleaned.

Description

[0001]The present application is based on, and claims priority from, the Taiwanese Republic of China application number 106128225, filed on Aug. 21, 2017, the disclosure of which is hereby incorporated by reference herein in its entirety.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The present invention relates to a robot, and more particularly to a cleaning robot comprising of a dust-collecting box and a sweeping and suction device.2. Description of the Prior Art[0003]With the penetration of various smart home devices into all aspects of life, in particular, cleaning robots can be regarded as one of the relatively skilled appliances, and by applying artificial intelligence control, cleaning robots can automatically move back and forth on the floor to clean up dust and dirt.[0004]Cleaning effect is one of the priorities of cleaning robots, and it will vary with the design of sweeping brushes and vacuuming modules, wherein the two designs need to coordinate with each oth...

AI Technical Summary

Benefits of technology

The invention is a device that helps cleaning robots to better clean surfaces. It has a feature that can sweep the surface and push dust and dirt away from it easily. This improves the cleaning effect of the cleaning robot. Another aspect is a dust-collecting box that can hold the collected dust and dirt, making it easier to dispose of it. Overall, this device helps to make cleaning robots better and more effective.

Problems solved by technology

However, the above-mentioned cleaning method use brushes to sweep the dust and dirt to the suction port, it fails to achieve desirable cleaning effect because the carpet is not flat and the brushes made of flexible materials cannot smoothly push the dust and dirt away from the carpet.

On the other hand, even if cleaning robots are designed with multiple suction ports, the cleaning robots cannot rely solely on negative pressure to draw all the dust and dirt from the carpet.
