When the notch 41 is squeezed and reduced when the working portion 30 meets an external obstacle, and when the edge of the notch 41 of the working portion 30 at least partially abuts against the surface of the transition section 20, the working portion 30 bends backward by the maximum curvature at this time, the working portion 30 does not bend any more, and the reaction force of the transition section 20 to the working portion 30 abuts against the ground while passing over the external obstacle, so that the ground is scraped clean.
In the first embodiment, the length of the working portion 30 is extended at an acute angle with respect to the floor (the acute angle formed by the working portion 30 and the floor is open toward the forward direction of the cleaning robot 200). Specifically, the notch 41 is squeezed and reduced when the working portion 30 encounters an external obstacle, so that the working portion 30 can smoothly escape from the external obstacle and continue to scrape the ground forward. As shown in FIG. 3, the distance from the edge of the notch 41 of the working portion 30 to the bottom of the notch 41 along the horizontal direction is the notch depth B (taking the maximum depth), and the distance from the edge of the notch 41 of the working portion 30 to the surface of the transition section 20 along the vertical direction is the notch width D (taking the maximum width), so that B/D is greater than or equal to 0.45 and less than or equal to 0.7. And the thickness of the junction 40 between the working portion 30 and the transition section 20 in the horizontal direction is 0.5mm to 1.5mm, as shown in fig. 3, for example equal to 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.5 mm.

The cleaning wiper strip 100 provided by the invention is assembled on the cleaning robot 200, the first end of the connecting head section 10 of the cleaning wiper strip 100 is connected and fixed to the corresponding mounting position 211 of the cleaning robot 200, the second end of the working part 30 of the cleaning wiper strip 100 extends out of the bottom of the cleaning robot 200 to be contacted with the ground, water in the wet cleaning piece 220 can remain on the ground and residual garbage is not completely cleaned after the cleaning piece 220 wipes the ground in the process of cleaning the ground, and the residual waste water and the residual garbage are wiped away because the cleaning wiper strip 100 is assembled at the rear end position of the cleaning piece 220. In the process that the notch 41 is squeezed and reduced when the working part 30 meets an external obstacle, when the edge of the notch 41 of the working part 30 abuts against the surface of the transition section 20, the working part 30 bends backwards by the maximum radian at the moment, the working part 30 does not bend continuously, and when the notch passes over the external obstacle, the notch 30 abuts against the ground by using the reaction force of the transition section 20 on the working part 30, so that the ground is scraped completely.
As shown in fig. 6, the cleaning member 220 is a rolling brush (the rolling brush can be used for mopping the floor by the surface of a mop cloth, or can be used for sweeping the floor by the surface of a brush). The rolling brush is assembled in the inner cavity 212 and extends out of the inner cavity 212 to roll and wipe the ground, one side of the rolling brush, facing the cleaning scraping strip 100, is arranged to be an arc-shaped surface matched with the outer contour of the rolling brush, and the cleaning scraping strip 100 and the rolling brush are arranged at intervals. Driving wheels 240 are provided near both ends of the roll brush, respectively, forward power is supplied through the driving wheels 240, and a universal wheel 250 is provided at the front end of the housing 210 in the forward direction, and when a speed difference is generated between the two driving wheels 240, the universal wheel 250 automatically adjusts the direction according to the speed difference to steer.
As shown in fig. 7 and 8, the cleaning robot 200 further includes a force bearing member 230, the force bearing member 230 is mounted on the wall of the inner cavity 212, and the side of the cleaning wiper strip 100 facing away from the cleaning member 220 abuts against the force bearing member 230. On the cleaning scraping strip, the connection part of the transition section 20 and the connecting section 10 is arranged in a turning shape to form a stress step 21, and the middle position of the transition section 20 is provided with the stress step 21. Correspondingly, the force bearing part 230 is provided with two matching steps corresponding to the two stress steps 21, and the two stress steps 21 are respectively and correspondingly meshed with and abutted against the two matching steps, so that in the advancing process of the cleaning robot 200, the force bearing part 230 applies force to the cleaning wiper strip 100, and the cleaning wiper strip 100 is stressed stably without deviation.
According to yet another aspect of the present invention, a cleaning system (not shown) is provided. Specifically, the cleaning system includes a cleaning base station (not shown) for cleaning the cleaning member 220 of the cleaning robot 200 and accommodating the cleaning robot 200 after the cleaning robot 200 completes the work of cleaning the floor, and the aforementioned cleaning robot 200. In fact, the cleaning base station can also be used for cleaning the cleaning elements 220 of the cleaning robot 200, because the floor area cannot be cleaned by the cleaning robot 200 at one time, the cleaning robot 200 needs to go and return the cleaning base station many times, each time the cleaning base station enters the cleaning base station, the cleaning elements 220 are cleaned by the cleaning base station, then the cleaning robot 200 is separated from the cleaning base station again to clean the floor, and so on until the cleaning robot 200 completely cleans the floor.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
