The following describes the specific process of cleaning the mopping member 90 of the cleaning robot 9 in the specific example of fig. 5-14, which is for the convenience of understanding only and should not be construed as limiting the invention.

Firstly, the cleaning robot 9 drives the head forward into the base station 1, the cleaning robot 9 advances, the water spraying pipe 70 located behind the cleaning roller 21 sprays water to the mopping member 90, when the head of the mopping member 90 starts to contact with the cleaning roller 21, the forward travel of the cleaning robot 9 makes the pressing device 80 abut on the top of the cleaning robot 9, and further makes the cleaning roller 21 provide a larger pressing force to the head of the mopping member 90, so that the cleaning of the mopping member 90 is started under the rotation of the cleaning roller 21. As the cleaning robot 9 continues to travel forward, the pressing device 80 remains in abutment against the top of the cleaning robot 9 to ensure that downward pressure is continuously given to the cleaning robot 9, so that the cleaning robot 9 can keep giving a large pressure to the cleaning roller 21, and in turn, the cleaning roller 21 keeps giving a large pressing force to the wiper 90. The cleaning roller 21 moves to the tail of the wiping member 90 to clean the tail of the wiping member 90, and the first sequential cleaning is completed. Specifically, it may be configured that only one time of sequential cleaning is completed, which means that the entire cleaning is completed, and at this time, the cleaning robot 9 may be driven away from the base station 1, and accordingly, the driving of the cleaning roller 21 may be stopped, and the water spraying from the water spraying pipe 70 may be stopped. Of course, when the cleaning of the cleaning robot 9 is not performed, the cleaning robot may move back and forth to perform a plurality of sequential cleaning operations, and during the cleaning operation, the rotation direction of the cleaning roller 21 may or may not be changed as required, and during the last sequential cleaning operation, the cleaning roller 21 may be rotated at a higher speed to squeeze off the excess water in the mop 90, so as to meet the requirement of the cleaning robot 9 during normal operation. When cleaning in order at least for the first time, cleaning roller 21 is driven with clockwise rotation to when guaranteeing to clean mopping piece 90, clear up rubbish forward, can not wipe the regional clearance of piece 90 cleaner with rubbish orientation, avoid causing secondary pollution, be favorable to promoting clean effect. During the moving cleaning of the cleaning robot 9, the scraper 30 scrapes off the garbage on the cleaning roller 21 during the rotation cleaning of the cleaning roller 21.

According to the specific example of the embodiment, the tail or other parts of the mop 90 may be cleaned first, and whether the cleaning is performed sequentially is not important, as long as the cleaning of the positions of the mop 90 can be completed finally.

Fig. 15 shows a second embodiment of the base station 1 and the cleaning robot system having the base station 1 according to the present invention.

The difference between this embodiment and the first embodiment mainly lies in the arrangement of the water spraying pipe 70.

On the basis of the solution in the first embodiment, the base station 1 in this embodiment further includes a water spraying pipe 70, the water spraying pipe 70 is used for spraying clean water onto the cleaning roller 21, and the rotation of the cleaning roller 21 can bring a part of the water onto the mop 90. Since the water spray pipe 70 sprays clean water onto the cleaning roller 21, the cleaning roller 21 can be washed and the cleaning roller 21 can bring a part of water onto the wiping member 90 by rotation for cleaning, thereby ensuring that each position of the cleaning roller 21 is always kept in a relatively clean state each time it is in contact with the wiping member 90, and further facilitating clean cleaning of the wiping member 90.

Of course, in other embodiments, it is not excluded to provide both the water spray conduit 70 spraying water directly onto the cleaning cylinder 21 and the water spray conduit 70 spraying water directly onto the mop 90, or the same water spray conduit 70 may spray water onto both the cleaning cylinder 21 and the water spray conduit 70.

On the basis of the corresponding technical solution in the first embodiment, the base station 1 in this embodiment further includes a water spraying pipe 70, the water spraying pipe 70 is used for spraying clean water onto the cleaning roller 21, and the rotation of the cleaning roller 21 can bring a part of the water onto the mopping member 90; when the cleaning roller 21 rotates in a predetermined direction, each contact position of the cleaning roller 21 contacts the wiping member 90, and then interferes with the scraping member 30, and is sprayed with water by the water spraying pipe 70.

Since the water spray pipe 70 sprays clean water onto the cleaning roller 21, the cleaning roller 21 can be washed and the cleaning roller 21 can bring a part of water onto the wiping member 90 by rotation for cleaning, thereby ensuring that each position of the cleaning roller 21 is always kept in a relatively clean state each time it is in contact with the wiping member 90, and further facilitating clean cleaning of the wiping member 90. When the cleaning roller 21 rotates in the preset direction, after each contact position of the cleaning roller 21 contacts with the wiping part 90, the cleaning roller firstly interferes with the scraping part 30 and then is sprayed with water by the water spraying pipeline 70, so that the cleaning roller 21 can firstly utilize the scraping part 30 to scrape residual garbage on the cleaning roller and then is cleaned by clean water sprayed by the water spraying pipeline 70, and further, the real-time cleaning in the rotating process of the cleaning roller 21 can be relatively thoroughly realized, and the cleaning effect of the cleaning roller 21 is powerfully ensured.

In addition, considering that the cleaning roller 21 may involve the change of the rotation direction during the cleaning of the wiping member 90, in this case, the water spraying pipes 70 may be provided on both sides of the cleaning roller 21 for selectively spraying water, or other methods may be adopted to ensure that the wiping member 90 contacts each contact position of the cleaning roller 21, and then the wiping member 30 is in interference contact with the wiping member, and then the water is sprayed by the water spraying pipes 70.

Of course, it is not excluded that the cleaning roller 21 is first sprayed with water by the water spraying pipe 70 and then brought into interference contact with the scraping member 30 after each contact position of the cleaning roller 21 is brought into contact with the wiping member 90 while the cleaning roller 21 is rotated in a predetermined direction.

Fig. 16 shows a third embodiment of the base station 1 and the cleaning robot system having the base station 1 according to the present invention.

In this embodiment, the traveling device 91 of the cleaning robot 9 is disposed at a different position from the mopping member 90, compared with the previous embodiments. In the present embodiment, the cleaning robot 9 includes a main running wheel 92 and an auxiliary running wheel 93 provided along the running direction thereof, the main running wheel 92 being provided between the mop 90 and the auxiliary running wheel 93; when the downward pressure is applied by the pressing device 80 in the cleaning process, one end of the cleaning robot 9, which is provided with the auxiliary walking wheel 93, is lifted upwards, one end of the cleaning robot 9, which is provided with the mopping piece 90, is pressed downwards on the cleaning roller 21, so that the auxiliary walking wheel 93 is suspended without special arrangement, or the landing place of the auxiliary walking wheel is compressible, or the universal wheel is compressible, the effect of obviously increasing the extrusion force of the cleaning roller 21 on the mopping piece 90 can be achieved, and the cleaning effect is effectively improved.

In the present embodiment, specifically, the auxiliary traveling wheel 93 is disposed at a head region of the cleaning robot 9, and the mop 90 is disposed at a tail region of the cleaning robot 9. In a particular example, when cleaning of the mop 90 is required, the cleaning robot 9 is advanced tail-first into the base station 1 to facilitate cleaning of the mop 90. In other embodiments, depending on the base station 1, the cleaning robot 9 may enter the base station 1 with its head facing forward. In addition, the auxiliary traveling wheel 93 may be disposed at a rear region of the cleaning robot 9, and the mop 90 may be disposed at a head region of the cleaning robot 9.

The following describes a specific process of cleaning the mop 90 of the cleaning robot 9 in the specific example of fig. 16, which is only for the convenience of understanding and should not be construed as a limitation of the present invention.

Firstly, the cleaning robot 9 drives into the base station 1 with the tail portion facing forward, the cleaning robot 9 moves forward, the water spraying pipe 70 sprays water to the mopping member 90, when the tail portion of the mopping member 90 starts to contact with the cleaning roller 21, the forward movement of the cleaning robot 9 makes the pressing device 80 abut against the top of the cleaning robot 9, so that the cleaning roller 21 can provide a larger pressing force to the tail portion of the mopping member 90, and the cleaning of the mopping member 90 is started under the rotation of the cleaning roller 21. As the cleaning robot 9 continues to travel forward, the pressing device 80 remains in abutment against the top of the cleaning robot 9 to ensure that downward pressure is continuously applied to the cleaning robot 9, so that the cleaning robot 9 can maintain a large pressure applied to the cleaning roller 21, and in turn, the cleaning roller 21 maintains a large pressing force applied to the wiper 90. Until the cleaning roller 21 moves relatively to the head of the wiping member 90 to clean the head of the wiping member 90, the first sequential cleaning is completed. Specifically, it may be configured that only one time of sequential cleaning is completed, which means that the entire cleaning is completed, and at this time, the cleaning robot 9 may be driven away from the base station 1, and accordingly, the driving of the cleaning roller 21 may be stopped, and the water spraying from the water spraying pipe 70 may be stopped. Of course, when the cleaning of the cleaning robot 9 is not performed, the cleaning robot may move back and forth to perform a plurality of sequential cleaning operations, and during the cleaning operation, the rotation direction of the cleaning roller 21 may or may not be changed as required, and during the last sequential cleaning operation, the cleaning roller 21 may be rotated at a higher speed to squeeze off the excess water in the mop 90, so as to meet the requirement of the cleaning robot 9 during normal operation. When cleaning in sequence at least for the first time, the cleaning roller 21 is driven to rotate anticlockwise so as to ensure that when the mopping piece 90 is cleaned, the garbage is not cleaned towards a cleaner area of the mopping piece 90, so that the secondary pollution is avoided, and the cleaning effect is favorably improved. During the moving cleaning of the cleaning robot 9, the scraper 30 continuously scrapes the garbage on the cleaning roller 21 during the rotation cleaning of the cleaning roller 21.

According to the specific example of the embodiment, the head or other parts of the mop 90 may be cleaned first, and whether the cleaning is performed sequentially is not important, as long as the cleaning of the positions of the mop 90 can be completed finally.

Fig. 17 shows a fourth embodiment of the base station 1 and the cleaning robot system having the base station 1 according to the present invention.

This embodiment is different from the first embodiment in the arrangement of the filter screen 40. In the specific example of the present embodiment, the scraping member 30 is also disposed on the filtering net 40, but the filtering net 40 is mainly located at a side corresponding to the garbage scraping direction of the scraping member 30, in which case, the cleaning roller 21 is usually set to rotate in a preset direction so that the scraping member 30 can always scrape the garbage toward the filtering net 40. Of course, in this embodiment, the scraping member 30 may not be provided on the filter screen 40, and it is sufficient that the filter screen 40 capable of receiving the scraped waste exists in the waste scraping direction of the scraping member 30.

In this embodiment, because the filter screen 40 is mainly or completely located at the side corresponding to the garbage scraping direction of the scraping member 30, preferentially, the water spraying section 71 of the water spraying pipeline 70 provided on the base station 1 in this embodiment is located at the other side of the scraping member 30 so as to be staggered with the filter screen 40, and then the corresponding relationship between the filter screen 40 and the water spraying section 71 when the installation is not considered, the filter screen 40 will not affect the water spraying operation of the water spraying pipeline 70, thereby being beneficial to the installation and the water spraying operation of the water spraying pipeline 70.

Please refer to fig. 1 to 17, the present invention further discloses a method for cleaning a cleaning robot 9 by using the base station 1, the base station 1 includes a cleaning roller 21 for cleaning a wiping member 90 at the bottom of the cleaning robot 9, the method for cleaning the cleaning robot 9 includes:

the cleaning robot 9 drives into the base station 1 and moves in the front-rear direction along the base station 1;

by the movement of the cleaning robot 9 in the forward and backward directions of the base station 1 and the rotation of the cleaning roller 21, the cleaning roller 21 cleans different portions thereof along the wiping member 90.

As an alternative embodiment, when the cleaning robot 9 is normally cleaning the floor, the cleaning robot 9 has a head facing forward, and the wiper 90 has a head that comes into contact with the debris first; the preset direction of rotation of the cleaning roller 21 is such that it clears the dirt from the mop 90 in the same direction as the head of the mop 90, at least for the first time the head of the mop 90 is being cleaned. Therefore, the garbage can not be cleaned towards a cleaner area of the mopping piece 90, so that secondary pollution is avoided, and the cleaning effect is favorably improved.

Specifically, at least during the first sequential cleaning along the wiping member 90, the cleaning roller 21 is rotated in a predetermined direction such that the direction in which the cleaning roller cleans the wiping member 90 of the waste is the same as the direction of the head of the wiping member 90, thereby ensuring that the cleaning roller does not clean the waste toward a relatively clean area of the wiping member 90 during at least the first successful cleaning.

In this case, the cleaning robot 9 first moves different portions of the wiping member 90 in a backward-forward or forward-backward movement to sequentially pass through the cleaning roller 21 to perform the first cleaning. If the cleaning member 90 cannot be cleaned after the first cleaning, the cleaning member can be moved back and forth by the cleaning robot 9 to continue cleaning, for example, the cleaning robot 9 can move back and forth again to sequentially clean different parts of the cleaning member 90 for multiple times, and during this process, the rotation direction of the cleaning roller 21 can be selectively changed or maintained.

When cleaning is specifically performed, a preset cleaning strategy can be established, and different cleaning strategies can be selected. For example, the cleaning robot 9 may be set to move back and forth a predetermined number of times, and the cleaning roller 21 may sequentially clean each part of the mop 90 once during each unidirectional movement; it is also possible to choose to focus the cleaning of the mop 90, for example, the cleaning robot 9 may stay for a preset time or may choose to move back and forth to a small extent while the focus is being cleaned.

As an alternative embodiment, when cleaning each part of the wiping member 90 for the last time, the rotation speed of the cleaning roller 21 is increased to squeeze the moisture on the wiping member 90. That is, in the case that the positions of the wiping member 90 need to be cleaned at least twice, the water on the wiping member 90 can be squeezed to the required degree when the cleaning robot 9 normally works by increasing the rotation speed of the cleaning roller 21 in the last cleaning, so that the cleaning robot 9 can be immediately put into operation after being driven away from the base station 1.

As an alternative embodiment, the base station 1 further comprises a scraping member 30 and a water spraying pipe 70, the scraping member 30 scrapes off the residual garbage on the cleaning roller 21 by interfering contact with the rotation of the cleaning roller 21, the water spraying pipe 70 is used for spraying clean water onto the cleaning roller 21, and the rotation of the cleaning roller 21 can bring a part of the water to the mopping member 90; the cleaning roller 21 rotates in a predetermined direction, and after each contact position of the cleaning roller 21 contacts the wiping member 90, the cleaning roller first interferes with the scraping member 30 and is sprayed with water by the water spraying pipe 70.

As an alternative embodiment, the base station 1 comprises pressure applying means 80; when the cleaning roller 21 performs squeeze cleaning on different parts of the cleaning roller along the wiping member 90, the pressing device 80 applies downward pressure on the cleaning robot 9 so that the cleaning robot 9 applies pressure on the cleaning roller 21. That is to say, when the cleaning roller 21 cleans the wiping member 90 in a squeezing type cleaning manner, the squeezing degree of the cleaning roller 21 to the wiping member 90 can be properly increased by the pressing device 80, and then the cleaning effect can be improved.

Specifically, when the cleaning roller 21 cleans different portions thereof along the wiping member 90, the pressing device 80 moves relatively along the top of the cleaning robot 9 to be pressed against different positions of the top of the cleaning robot 9.

Specifically, the cleaning robot 9 includes a main running wheel 92 and an auxiliary running wheel 93 provided along its running direction, the main running wheel 92 being provided between the mop 90 and the auxiliary running wheel 93; when a downward pressure is applied by the pressing device 80 during cleaning, the end of the cleaning robot 9 provided with the auxiliary traveling wheel 93 is lifted upward, and the end of the cleaning robot 9 provided with the mop 90 is pressed downward against the cleaning roller 21 (as shown in fig. 16). Under this condition, need not to carry out special setting and make supplementary walking wheel 93 unsettled, perhaps make its landing place compressible, perhaps the universal wheel is compressible again, can play the effect that shows the extrusion force that increases cleaning roller 21 to mopping piece 90 equally, has effectively promoted clean effect.

As an alternative embodiment, the cleaning robot 9 includes a main running wheel 92 and an auxiliary running wheel 93 provided along its running direction, the mop 90 being located between the main running wheel 92 and the auxiliary running wheel 93; the auxiliary traveling wheel 93 is suspended while the cleaning roller 21 cleans different portions thereof along the wiping member 90. That is to say, in the process of cleaning the mop 90 by the cleaning roller 21, the auxiliary traveling wheel 93 of the cleaning robot 9 is kept in a suspended state, and further, under the condition that the pressure is applied by the pressure applying device 80, it can be ensured that most of the pressure applying device 80 acts on the cleaning robot 9, pressure loss due to the fact that the auxiliary traveling wheel 93 is supported is avoided, the extrusion force of the cleaning roller 21 on the mop 90 is effectively increased, and therefore the cleaning effect is further improved.
