Therefore, the driving mechanism can finally drive the rib structure 21 to perform a relative motion with respect to the mop 101 (at this time, the mop 101 may be kept stationary with respect to the ground on the cleaning robot 100, the mop 101 may also perform a relative motion with respect to the ground on the cleaning robot 100, and a motion direction of the relative motion of the mop 101 with respect to the ground is opposite to a motion direction of the relative motion of the rib structure 21 with respect to the ground).
Specifically, the driving mechanism comprises a power motor and a transmission assembly, the transmission assembly can adopt a reduction gear box or a gear rack transmission structure, the power motor is connected with the transmission assembly, the power motor outputs power to the transmission assembly, the transmission assembly is connected with the base 23 or the convex rib structure 21, the transmission assembly transmits the power to the base 23 or the convex rib structure 21, and finally the convex rib structure 21 is driven to move relatively to the mopping piece 101.
Alternatively, in embodiments of the present invention, the drive mechanism may also be a vibratory drive mechanism, a pendulum drive mechanism, or a rotary drive mechanism. When the driving mechanism selects the vibration driving mechanism, the vibration part of the vibration driving mechanism is connected with the connecting plate, the vibration driving mechanism drives all the convex rib structures 21 on the connecting plate to continuously vibrate with the mopping part 101, so that the second side convex ribs 2111 abut against the mopping part 101 to extrude the sewage in the mopping part 101, at the moment, a plurality of spray heads are linearly arranged in each liquid storage tank 211 along the length direction of the tank, and in the vibration process, the spray heads spray liquid, so that the mopping part 101 can be soaked in the liquid. When the driving mechanism selects the swing driving mechanism, the swing part of the swing driving mechanism is connected with the connecting plate. Similarly, when the rotation driving mechanism is selected as the driving mechanism, the rotating portion of the rotation driving mechanism is connected to the connecting plate, so that the rotation driving mechanism drives all the rib structures 21 on the connecting plate to rotate continuously in one direction (clockwise or counterclockwise) relative to the mop 101, and at this time, the mop 101 may be kept stationary relative to the ground, or the mop 101 may rotate relative to the ground, but the rotation direction of the mop 101 relative to the ground is opposite to the rotation direction of the connecting plate relative to the ground. The horizontal movement of the convex rib structure and the vertical movement of the mopping piece can be replaced by the swinging of the convex rib structure 21, the relative movement between the mopping piece 101 and the convex rib structure 21 is swinging, the convex rib structure can be provided with a swinging structure to swing upwards in the initial working position, the convex rib on the second side of the convex rib structure is extruded to the mopping piece and the liquid storage tank is moved to the lower part of the mopping piece for liquid absorption in the upward swinging process, the initial position is swung back in the downward swinging process, the horizontal movement is replaced by the swinging mode, the mopping piece of the cleaning robot can be prevented from moving upwards, and the liquid on the mopping piece is prevented from being extruded back to the liquid storage tank by the convex rib on the second side. The specific swing structure may be a link mechanism such as a crank and a rocker, or may be a structure capable of swinging. Alternatively, other relative movements between the rib structure and the scrubbing element may be used for the superposition. For example, when the rib structure swings, the vibration or rotation of the mopping piece is combined; for another example, the convex rib structure vibrates or translates, and is cleaned by combining the rotation of the mopping piece; for another example, the rib structure rotates in combination with the vibration or rotation of the mop, and at this time, there is a rotation speed difference between the rotation of the rib structure and the rotation of the mop or the rotation directions of the rib structure and the mop are opposite.
In this embodiment, the relative movement between the mop 101 and the rib structure 21 is preferably: the dragging piece 101 translates relative to the rib structure 21, and the translation may be a movement in a single direction, in this case, the dragging piece 101 may be rectangular, circular, oval, or other shapes; alternatively, the scrubbing member 101 may rotate relative to the rib structure 21, wherein the scrubbing member 101 is circular.
Preferably, the cleaning mechanism 20 further includes a drain structure (not shown) connected to the connecting plate, the drain structure being a waste tank or drain. The drain structure is connected to all of the drain holes 213 so as to drain the dirty liquid squeezed out of the mop 101 to the drain structure, and when the drain structure is a sewage tank, the sewage tank stores the sewage, and when the sewage tank is about to be full, the sewage tank can be lifted up to dump the sewage clean and then store the sewage; when the drainage structure is a sewage discharge pipe, the sewage discharge pipe is directly communicated to a sewer to directly drain sewage.
It should be noted that the first side rib 2112 and the second side rib 2111 have a height difference of less than 3cm, when the second side rib 2111 is pressed and scraped by the wiping member 101, the non-pressed portion of the wiping member 101 and the top wall of the second side rib 2111 may just abut against each other, or may not contact each other, or may interfere with each other, and when interfering with each other, the second side rib 2111 may also have a little scraping effect. In addition, the first side ribs 2112 and/or the second side ribs 2111 may also be provided with protruding structures such as bumps or protruding strips to assist scraping.

This is to flow liquid (for example, clean water) into the reservoir 211 of the cleaning mechanism 20, and since the mop 101 can be immersed into the clean water in the reservoir 211 to absorb the clean water, the dirt on the mop 101 is diluted by the clean water absorbed by the mop 101, and then the rib structure 21 and the mop 101 move relatively, at this time, the top of the second side rib 2111 is kept abutting against the mop 101, so that the sewage in the mop 101 is squeezed out to the side of the second side rib 2111 far from the first side rib 2112 and flows into the drainage chamber 212.
In the cleaning base station, the cleaning base station further includes a control module (not shown) and a position sensing device (not shown), the control module is connected to the position sensing device and the cleaning mechanism 20, the position sensing module is used for sensing the relative position of the cleaning robot 100 with respect to the base 10, and when the cleaning robot 100 stops at the stop station 11 of the base 10, the control module controls the cleaning mechanism 20 to clean the mopping member 101 of the cleaning robot 100.
In the process of cleaning the floor in the room, the cleaning robot 100 cannot clean the floor at one time, so that the floor needs to go to and fro the base station several times, clean the mop 101 in the base station, then leave the base station to clean the floor again, and clean the floor completely for several times. The cleaning robot 100 stops at the parking station 11 every time it enters the cleaning base station, the mopping piece 101 is located in the area of the rib structure 21 of the cleaning mechanism 20, the control module controls the pump of the water supply mechanism 22 to pump clean water to the reservoir 211, meanwhile, the control module is electrically connected with the cleaning robot 100, the control module sends a control command to the cleaning robot 100, the cleaning robot 100 controls the mopping piece 101 to move relative to the ground according to the control command, and the control module controls the driving mechanism of the cleaning mechanism 20 to work to drive the rib structure 21 to move relative to the ground, so that, relative movement of the mop 101 and the rib structure 21 is directly generated, and the top of the second side rib 2111 is held in abutment with the mop 101, thereby squeezing the liquid from the mop 101 out to the side of the second side rib 2111 remote from the first side rib 2112 and into the drain chamber 212 for drainage.
According to still another aspect of the present invention, there is provided a cleaning robot system. Specifically, the cleaning robot system includes the cleaning robot 100 and the aforementioned cleaning base station.
