[0019] The cross section of the liquid outlet groove is trumpet-shaped, gradually expanding from one end of the liquid outlet to the top

[0020] The advantages or principles of the present invention are described below:

[0021] 1. A cleaning mechanism and a power mechanism are arranged on the shell of the mopping robot, wherein the wiping cloth is installed in such a way that it passes through the power mechanism and extends out from the first port, goes around to the bottom of the shell, and extends into the shell from the second port. The wiping cloth is located at the bottom of the cleaning brush. During operation, the power mechanism located at the first port is started to drive the wiping cloth to move. The moving wiping cloth passes through the bottom of the shell, contacts the ground, and wipes the ground. After wiping, the wiping cloth continues to move and enters the shell from the second port. The cleaning mechanism cleans the wiping cloth, wherein the cleaning brush brushes the wiping cloth to brush the dirt and dust off the surface of the wiping cloth, and then a water pump is used to drive the water flow, and then the water flow cleans the wiping cloth to wash away the dirt and dust. In this mopping process, the wiping cloth is cyclically cleaned and wiped, and the wiping cloth is more clean after repeated cleaning.

[0022] 2. The power mechanism includes a driving wheel, a driven wheel and a first motor. The driving wheel and the driven wheel are parallel to each other and there is a gap between them. The wiping cloth passes through the gap. In addition, the driving wheel is driven by the first motor to rotate. The driving wheel and the driven wheel clamp the wiping cloth. The driving wheel rotates to drive the wiping cloth to move outward, providing power to the wiping cloth. Not only that, the wiping cloth is squeezed between the driving wheel and the driven wheel. The wiping cloth is continuously squeezed during the rolling process to squeeze out the water on the wiping cloth, thereby ensuring that the wiping cloth has less residual water when wiping the ground, and no water will accumulate on the ground.

[0023] 3. A card slot is provided at the first port, and a card convex is movably connected to the other side of the driving wheel relative to the first motor. The card slot and the card convex cooperate with each other. During installation, the driving wheel and the card convex are installed first, and then the driving wheel and the card convex are installed at the first port of the shell, and the card convex is then inserted into the card slot, so it is easy to install.

[0024] 4. In addition, a first connecting hole is provided on the side wall of the groove, and a second connecting hole is provided on the card convex. The positional relationship between the first connecting hole and the second connecting hole corresponds to each other, and then the card convex is fixed to the first connecting hole and the second connecting hole through a nail body. The card convex can be firmly inserted into the card slot, making the driving wheel more secure and convenient for disassembly and replacement of the wiping cloth.

[0025] 5. The shell is recessed from the outer bottom to the inner side to form a pump chamber. Installing the water pump in this position will not affect the wiping cloth wiping the ground at the bottom. The water pump and the water body can be separated by a dedicated pump chamber. The circuit part of the water pump will not be soaked in the cleaning fluid, which is safer and more durable.

[0026] 6. A liquid outlet groove is provided at the lower part of the first port of the shell, which is connected to the liquid outlet. The water pump drives the cleaning liquid out, and then disperses through the long strip opening at the top of the liquid outlet groove to rinse the wiping cloth. Moreover, it is arranged at the bottom of the first port so that the water flow can rinse for a longer distance and the rinse effect is better.

[0027] 7. A wiring hole is provided in the pump chamber, and a wiring conduit is provided on the shell wall. One end of the wiring conduit is connected to the wiring hole, and the other end passes through the outer wall of the shell. The circuit is separated from the cleaning fluid, and then an electrical connection is made using a power supply provided on the outside of the shell to supply power.

[0028] 8. A guide plate is installed inside the shell, and the top surface of the guide plate is smooth. The cleaning brush is on the top of the guide plate, and the wiping cloth is between the guide plate and the cleaning brush. The wiping cloth will not be blocked when passing through the guide plate, and then the cleaning brush can also brush the wiping cloth. The wiping cloth can play a supporting role when brushing on the guide plate, so that the brushing effect is better.

[0029] 9. A curved rail groove is provided at the bottom of the guide plate. The flow rate of the cleaning liquid is reduced after passing through the rail groove, and then the cleaning liquid enters the curved rail groove, where a notch is provided at the port, so that the cleaning liquid enters the liquid inlet for water circulation.

[0052] Advantages of this embodiment:

[0053] 1. A cleaning mechanism and a power mechanism 30 are provided on the robot shell 10, wherein the wiping cloth 40 is installed in such a manner that it passes through the power mechanism 30, extends from the first port 11, goes around the bottom of the shell 10, and extends into the shell 10 from the second port 12. The wiping cloth 40 is located at the bottom of the cleaning brush 21. During operation, the power mechanism 30 located at the first port 11 is started to drive the wiping cloth 40 to move. The moving wiping cloth 40 passes through the bottom of the shell 10, contacts the ground, and wipes the ground. After wiping, the wiping cloth 40 continues to move and enters the shell 10 from the second port 12. The cleaning mechanism cleans the wiping cloth 40, wherein the cleaning brush brushes the wiping cloth 40 to brush the dirt and dust out of the surface of the wiping cloth 40, and then uses the water pump 22 to drive and form a water flow, and then the water flow cleans the wiping cloth 40 to wash away the dirt and dust. In this mopping process, the wiping cloth 40 is cyclically cleaned and wiped, and the wiping cloth 40 is repeatedly cleaned to be cleaner.

[0054] 2. The power mechanism 30 includes a driving wheel 31, a driven wheel 32 and a first motor 33.
