In some embodiments, the outer wall of the liquid storage tank 30 is provided with a communication contact 301, the liquid storage tank 30 is mounted to the main body 100, and is in communication with the controller 50, if the cleaning robot enters a first cleaning mode, the controller 50 controls the liquid applying device 80 to periodically apply the liquid in the liquid storage tank 30 to the outside or the cleaning member 10 via the liquid applying pipe 81 and the liquid outlet part 70; if the cleaning robot enters the second cleaning mode, the controller 50 controls the liquid applying device 80 to stop applying the liquid. The liquid stored in the reservoir 30 may be clear water or cleaning liquid. With specific reference to fig. 10, fig. 10 is a flow chart of liquid application during operation of the cleaning robot according to an embodiment of the present invention.

S10, the cleaning robot starts working, the trigger condition for the cleaning robot to start working may be manual trigger or self-starting of the cleaning robot, and the manual trigger mode may be pressing a switch button to start working the cleaning robot or starting working the cleaning robot by giving a signal to start working to the cleaning robot through a remote controller, an App, or other mobile terminal device. The cleaning robot self-start may be a cleaning robot self-start to operate by the time of completion of charging or scheduled start of operation through a memory function of the controller 50. After the cleaning robot starts working, the working mode of the cleaning robot needs to be judged in real time, and the liquid application modes in the liquid storage tank 30 are controlled to be different in different working modes.

The S20 cleaning robot enters a first cleaning mode, and the S40 liquid applying device periodically applies the liquid in the liquid storage tank to the outside or the cleaning piece through the liquid applying pipe and the liquid outlet part. The first mode of operation of the cleaning robot is a mode in which liquid can be applied to the cleaning elements 10 or outwardly, and is in a normal operating condition when the cleaning robot is running on a floor surface without getting trapped. The controller 50 controls the driving motor 850 to drive the rotating disc 830 to rotate, and the squeezing portion 835 periodically squeezes the connecting pipe 802, so as to uniformly and sequentially segment the liquid in the liquid storage tank 30 from the liquid inlet pipe 801 to the liquid outlet pipe 803 via the connecting pipe 802, and then the liquid enters the liquid outlet part 70 and flows from the liquid outlet 701 to the cleaning member 10 or is sprayed out from the liquid outlet 701. The controller 50 can also control the rotation speed of the driving motor 850 to drive the rotating disc 830 to rotate, so that the same amount of water is extruded at different time, and the liquid outlet rate is controlled.

The S30 cleaning robot enters the second cleaning mode and the S50 liquid applying means stops applying the liquid. When the cleaning robot walks to a soft surface to be cleaned, it can be determined that the cleaning robot enters the second cleaning mode, and the liquid applying device 80 stops applying the liquid to the cleaning member 10 or applies the liquid to the outside.

When the cleaning robot enters the charging mode, the cleaning robot can be judged to enter the second cleaning mode, and the cleaning robot needs to stop applying liquid when entering the mode of finding and recovering the charging seat or when charging is carried out on the charging seat. When the cleaning robot searches for the recharging seat, the walking speed is reduced, the cleaning effect is poor, and secondary pollution is easily caused by continuously applying liquid. The cleaning robot enters into charging after the charging contact of the charging seat is successfully butted, and stops applying liquid, so that the liquid is prevented from flowing out to contact with the charging contact of the charging seat, and short circuit of a charging circuit is prevented or other potential safety hazards are prevented. When the cleaning robot is in the abnormal working state, it may be judged that the cleaning robot enters the second cleaning mode, and the abnormal working state may be that the cleaning robot is trapped or stuck. The cleaning robot enters the second cleaning mode, which may be one or more of the above. When the cleaning robot enters the second operation mode, the controller 50 controls the driving motor 850 to stop driving, the rotating disc 830 stops rotating, the pressing portion 835 keeps pressing the connection pipe 802, prevents the liquid from flowing through the connection pipe 802, and stops applying the liquid to the cleaning member 10 or to the outside.

In this embodiment, the cleaning robot enters different cleaning modes according to different actual working conditions, and in the corresponding cleaning modes, the controller 50 can effectively control whether the liquid in the liquid storage tank 30 continuously flows to the cleaning member 10 or whether the liquid is continuously sprayed outwards, so that the liquid application of the cleaning robot is intelligently controlled. And the liquid applying device 80 comprises a liquid applying pipe 81 and a power component 82, the liquid applying pipe 81 comprises a liquid inlet pipe 801, a liquid outlet pipe 803 and a connecting pipe 802, the power component 82 further comprises a driving motor 850 and a rotating disc 830 which are installed on the installation part 820, the rotating disc 830 is provided with an extrusion part 835, the rotating disc 830 is driven by the driving motor 850 to rotate, the extrusion part 835 extrudes the connecting pipe 802, the liquid in the liquid storage tank 30 is uniformly and sequentially distributed from the liquid inlet pipe 801 to the liquid outlet pipe 803 through the connecting pipe 802 in a segmented mode, and then the liquid enters the liquid outlet component 70 and flows out from the liquid outlet 701, so that the water supply of the cleaning robot is stable.

In the embodiment, the cleaning robot includes main part 100, drive cleaning robot is treating drive wheel 20 that cleans the face and is removing, stock solution tank 30, the clean piece 10 and the liquid applying device 80 of cleaning the face of waiting to clean, liquid applying device 80 includes that liquid applies pipe 81 and power part 82, liquid applies pipe 81 and includes feed liquor pipe 801, drain pipe 803, connecting pipe 802, feed liquor pipe 801 one end with stock solution tank 30 is connected, go out liquid part 70 is connected to the one end of drain pipe 803, the both ends of connecting pipe 802 are connected respectively feed liquor pipe 801's the other end and drain pipe 803's the other end, power part 82 is configured as with liquid in feed liquor pipe 801 periodically carry to drain pipe 803, realize cleaning robot passes through liquid applying device 80 with the liquid in stock solution tank 30 via liquid apply pipe 81 and go out liquid part 70 periodically The liquid is applied to the cleaning piece 10, the liquid outlet rate or the liquid outlet amount of the liquid is effectively controlled, the liquid supply of the cleaning robot is stable, the cleaning robot can have different liquid supply modes, and the user experience is improved.
