The utility model provides a base station 100 and a cleaning robot system 1000, and aims to solve the technical problems of high labor intensity and poor user experience caused by the fact that the base station 100 needs to manually clean a sewage collection place in the base station 100 in the prior art.

The specific structure of the base station 100 of the present utility model will be described below:

referring to fig. 1 to 5 in combination, in an embodiment of the base station 100 of the present utility model, the base station 100 is configured to be capable of cleaning the cleaning robot 200; the base 10 has a sump 11; the nozzle 20 is provided to the base 10, and the nozzle 20 can spray liquid toward the sump 11 to clean the dirt adhered to the sump 11.

It can be appreciated that in the base station 100 provided by the utility model, when the cleaning structure in the base station 100 cleans the cleaning member 220 of the cleaning robot 200, a plurality of dirty objects such as hairs, sludge and the like which cannot be timely recovered along with sewage are attached to the surface of the sewage collecting place (the sewage tank 11), at this time, the nozzle 20 works, can spray liquid into the sewage tank 11, and can clean the dirty objects attached to the sewage tank 11, so that the nozzle 20 can automatically clean the dirty objects on the sewage collecting place (the sewage tank 11), and the cleaning and maintenance of the sewage collecting place in the base station 100 are not required, thereby solving the technical problems of high labor intensity and poor user experience.

When spraying liquid into the sewage tank 11, the nozzle 20 may spray liquid with or without impact force, as long as it is sufficient to clean the sewage tank 11 of the dirt adhering thereto.

It should be noted that, the nozzle 20 may be capable of spraying liquid toward the sump 11, which may mean that the nozzle 20 may be capable of spraying liquid only toward the sump 11, or may mean that the nozzle 20 may be capable of spraying liquid toward other structures to be cleaned (e.g., the cleaning member 220 of the cleaning robot 200, a cleaning structure for cleaning the cleaning member 220, etc.) in addition to spraying liquid toward the sump 11.

In the practical application process, the nozzle 20 may be mounted on the wall of the sewage tank 11, or may be mounted at a position higher than any wall surface of the bottom surface of the sewage tank 11, or may be mounted at the bottom of the sewage tank 11. For example, a mounting opening may be formed on a wall of the sewage tank 11, and the nozzle 20 may be disposed at the mounting opening in a penetrating manner, so that the nozzle 20 may spray liquid toward the sewage tank 11; and, the cleaning liquid may be supplied to the nozzle 20 through a water supply pipe.

Further, in the embodiment of the present application, referring to fig. 2, 4 and 5 in combination, the sump 11 has a drain 111, and the drain 111 is used for discharging the dirt in the sump 11.

In this way, the nozzle 20 is operated to spray the dirt on the sewage tank 11, and then the dirt can be discharged out of the sewage tank 11 through the water outlet 111, so as to achieve the purpose of automatically cleaning the dirt on the sewage tank 11.

In practical applications, the drain opening 111 may be disposed at any position of the bottom wall of the sump 11, and of course, in order to enable the dirt in the sump 11 to quickly pass through the drain opening 111 and drain, in an embodiment, the drain opening 111 may be disposed in the middle of the bottom wall of the sump 11, so that the dirt at the edge of the sump 11 is concentrated and flows out to the drain opening 111 in the middle.

Further, in the embodiment of the present application, referring to fig. 2, 4 and 5 in combination, the bottom wall of the sump 11 has the water guide 112 disposed obliquely, and the height of the water guide 112 gradually decreases from the side far from the drain port 111 to the side near the drain port 111.

By using the phenomenon that water flows downwards, the bottom wall of the sewage tank 11 is provided with the water guide part 112 which is obliquely arranged, the height of the water guide part 112 gradually decreases from the side far away from the water outlet 111 to the side close to the water outlet 111, and after the nozzle 20 sprays liquid to the sewage tank 11 to spray the dirt on the sewage tank 11, the dirt can smoothly flow to the water outlet 111 under the guide of the water guide part 112, so that the phenomenon that water accumulation exists in the sewage tank 11 is avoided.

For example, in an embodiment, the bottom wall of the sewage tank 11 may be divided into a first bottom wall and a second bottom wall which are bilaterally symmetrical, and the first bottom wall and the second bottom wall are connected to provide the water discharge port 111 at the junction of the first bottom wall and the second bottom wall, so that the height of the water guide portion 112 on the first bottom wall may gradually decrease from the side away from the water discharge port 111 (the side away from the second bottom wall) to the side close to the water discharge port 111, and at the same time, the height of the water guide portion 112 on the second bottom wall may gradually decrease from the side away from the water discharge port 111 (the side away from the first bottom wall) to the side close to the water discharge port 111. In another embodiment, the sump 11 may be a unitary sump structure, similar to a washbasin.

Further, in the embodiment of the present application, referring to fig. 2, 4 and 5 in combination, the nozzle 20 sprays liquid along a side away from the drain port 111 to a side close to the drain port 111 to spray dirt attached to the wall of the sump 11 toward the drain port 111, that is, the nozzle 20 can be moved from the side away from the drain port 111 to the side close to the drain port 111.

By this arrangement, the dirt on the sewage tank 11 can be sprayed down and quickly toward the drain outlet 111 under the action of the nozzle 20, so as to improve the sewage draining efficiency.

In another embodiment, the spray direction of the nozzle 20 may be along a side away from the drain opening 111 to a side close to the drain opening 111, i.e., the nozzle 20 may be directed to spray the drain opening 111 to spray the dirt on the sump 11 down and toward the drain opening 111.

Further, in the embodiment of the present application, referring to fig. 2, fig. 4 and fig. 5 in combination, at least two nozzles 20 are provided, and at least two nozzles 20 may be disposed opposite to each other, or disposed on the same side, or disposed on different sides.

By this arrangement, the sewage tank 11 can be cleaned by at least two nozzles 20 at the same time, thereby improving the cleaning effect of the sewage tank 11.

For example, two nozzles 20 may be provided, and both nozzles 20 are provided on the wall of the sump 11, and are disposed opposite to each other, or on the same side wall of the sump 11, or on two adjacent side walls of the sump 11, respectively; alternatively, the nozzles 20 may be provided in three, the three nozzles 20 are all provided on the wall of the sump 11, and the three nozzles 20 are arranged at intervals in the circumferential direction of the sump 11, and two of the nozzles 20 are arranged opposite to each other (i.e., two of the nozzles 20 are arranged on two opposite side walls of the sump 11), or two of the nozzles 20 are arranged on the same side wall of the sump 11, or two of the nozzles 20 are respectively arranged on two adjacent side walls of the sump 11; alternatively, four nozzles 20 may be provided, and four nozzles 20 may be provided on the wall of the sewage tank 11, two of the nozzles 20 may be provided opposite to each other, and the other two nozzles 20 may be provided opposite to each other, for example, four nozzles 20 may be provided on the four walls of the sewage tank 11, respectively; alternatively, the four nozzles 20 may be provided on the same side wall of the sewage tank 11; alternatively, four nozzles 20 may be provided on two adjacent side walls of the sump 11, respectively, for example, one of the nozzles 20 may be provided on one side wall of the sump 11 and the other three nozzles 20 may be provided on the other side wall of the sump 11; alternatively, two of the nozzles 20 may be provided on one side wall of the sump 11, and the other two nozzles 20 may be provided on the other side wall of the sump 11.

Further, in the embodiment of the present application, referring to fig. 7 in combination, the base station 100 further includes a control valve 60, where the control valve 60 has a liquid inlet 611 and at least two liquid outlets 612, each liquid outlet 612 is connected to a nozzle 20, and the control valve 60 is used for controlling at least one nozzle 20 to spray liquid.

So configured, the cleaning fluid may enter through the inlet 611 of the control valve 60 and then be split to at least two outlets 612 to provide cleaning fluid to at least two nozzles 20, respectively, so as to control the spraying of one or more of the nozzles 20.

It should be noted that, in one embodiment, the control valve 60 may control at least two nozzles 20 to spray liquid simultaneously; in another embodiment, the control valve 60 may control at least two nozzles 20 to spray liquid in a time-sharing manner, for example, the control valve 60 controls a part of the nozzles 20 to spray liquid first, and after the part of the nozzles 20 operate for a period of time, controls the part of the nozzles 20 to stop operating, and then controls another part of the nozzles 20 to spray liquid; alternatively, a part of the nozzles 20 is controlled to spray liquid by the control valve 60, and after a certain period of time, another part of the nozzles 20 is controlled to spray liquid, and at this time, all the nozzles 20 can start to operate.

It should be noted that, when the control valve 60 is used to control the simultaneous spraying of the liquid from at least two nozzles 20, the spraying water pressure of the at least two nozzles 20 may be ensured by increasing the power of the pump body, or by reducing the loss of the flow of the cleaning liquid in the control valve 60, or by reducing the aperture of the nozzles 20.

In the practical application process, the nozzle 20 may be directly connected to the liquid outlet 612 of the control valve 60, or may be indirectly connected to the liquid outlet 612 of the control valve 60.

For example, the nozzle 20 may be directly connected to the liquid outlet 612 of the control valve 60 by a threaded connection, for example, an external thread is provided on an outer surface of the nozzle 20, and an internal thread is provided on an inner wall surface of the liquid outlet 612, that is, the nozzle 20 may be connected to the liquid outlet 612 under the cooperation of the external thread and the internal thread; alternatively, the nozzle 20 may be directly adhesively attached to the control valve 60 at the outlet 612.

Further, in the embodiment of the present application, referring to fig. 2, 4 and 5 in combination, the nozzle 20 may be rotated and/or moved with respect to the sump 11 to change the spray direction of the nozzle 20.

Thus, the nozzle 20 can be rotated or moved to adjust the spraying direction of the nozzle 20 so that the nozzle 20 faces different positions, for example, the nozzle 20 can spray liquid at each position of the sewage tank 11 to improve the cleaning effect of the sewage tank 11; alternatively, the nozzle 20 may be used to spray the cleaning member 220 or the cleaning structure 50 for cleaning the cleaning member 220 by adjusting the spray direction of the nozzle 20 so that the nozzle 20 sprays the cleaning member 220 or the cleaning structure 50 for cleaning the cleaning member 220; alternatively, at least two of the nozzles 20 may be controlled by different motors so that the nozzles 20 may be oriented in different positions to simultaneously clean the different positions.

Of course, in other embodiments, since the nozzle 20 can be rotated and/or moved with respect to the sump 11, only one nozzle 20 may be provided to spray the liquid at various positions of the sump 11 by changing the spray direction of the nozzle 20.

The direction of spraying the liquid from the nozzle 20 is the direction along the central axis of the water outlet of the nozzle 20.

Further, in the embodiments of the present application, referring to fig. 2, 4 and 5 in combination, the nozzle 20 rotates and has a first spray angle, a second spray angle and a third spray angle;

when the nozzle 20 is at the first spray angle, the nozzle 20 is used for spraying liquid towards the cleaning member 220;

when the nozzle 20 is at the second spray angle, the nozzle 20 is used for spraying liquid towards the cleaning structure 50 for cleaning the cleaning member 220 of the cleaning robot 200;

when the nozzle 20 is at the third spray angle, the nozzle 20 sprays liquid toward the sewage tank 11.

The arrangement can control the spray angle of the nozzle 20 according to the cleaning process, for example, when the cleaning member 220 needs to be cleaned, the nozzle 20 can be controlled to be adjusted to the first spray angle (the first spray angle can be a specific position or a range, for example, the first spray angle can be a non-fixed angle, the nozzle 20 can rotate within the first spray angle range to spray the cleaning member 220), and at this time, the nozzle 20 can operate to spray the cleaning member 220; for another example, after the cleaning member 220 is cleaned, the nozzle 20 may be controlled to adjust to the second spray angle (may be a specific position or a range, for example, the second spray angle may be a non-fixed angle, and the nozzle 20 may rotate within the second spray angle range to perform spray cleaning on the bottom surface of the cleaning structure 50), where the nozzle 20 may operate to perform spray cleaning on the bottom surface of the cleaning structure 50; also, for example, after the cleaning structure 50 is cleaned, the nozzle 20 may be controlled to adjust to the third spray angle (may be a specific position or a range, for example, the third spray angle may be a non-fixed angle, and the nozzle 20 may rotate within the third spray angle range to spray the liquid for cleaning the sewage tank 11), where the nozzle 20 may work to clean the sewage tank 11. Of course, the liquid spraying cleaning may be performed not in the above sequence, but the liquid spraying angle of the nozzle 20 may be controlled according to the cleaning requirement, for example, when the sewage tank 11 is cleaned, the nozzle 20 may be controlled to be always at the third liquid spraying angle.

For example, the liquid spray angle when the liquid spray direction of the nozzle 20 is directed directly above is 0 degrees, and the liquid spray angle when the liquid spray direction of the nozzle 20 is directed directly below is 180 degrees, so that the first liquid spray angle of the nozzle 20 may be 0 to 30 degrees, the second liquid spray angle of the nozzle 20 may be 30 to 90 degrees, and the third liquid spray angle of the nozzle 20 may be 90 to 180 degrees.

Further, in the embodiment of the present application, referring to fig. 3 in combination, the base station 100 further includes a driving member 30, where the driving member 30 is disposed on the base 10 and is drivingly connected to the nozzle 20 to drive the nozzle 20 to rotate and/or move. So configured, the driving member 30 may rotate and/or move the nozzle 20 to rotate the nozzle 20 to the first spray angle, the second spray angle, the third spray angle, or move the nozzle 20 to the first position, the second position, or the third position.

The driving member 30 may be a motor, the motor is fixedly mounted on the base 10, the nozzle 20 is connected to an output shaft of the motor to rotate along with the output shaft of the motor, and the spraying direction of the nozzle 20 and the axial direction of the output shaft form an included angle, so that the nozzle 20 can be driven to rotate under the rotation of the output shaft to adjust the spraying angle of the nozzle 20; of course, the driving member 30 may also be a combination structure of a telescopic cylinder and a rack and pinion, specifically, the telescopic cylinder is fixedly mounted on the base 10, the rack is connected to a telescopic portion of the telescopic cylinder to extend and retract along with the telescopic portion, the pinion 31 is meshed with the rack to drive the pinion 31 to rotate under the movement of the rack, the nozzle 20 is connected to the pinion 31 to rotate along with the pinion 31, and, referring to fig. 6, a spraying direction (a first direction) of the nozzle 20 and a rotation axis direction (a second direction) of the pinion 31 are disposed at an included angle, so that the nozzle 20 can be driven to rotate under the rotation of the pinion 31 to adjust a spraying angle of the nozzle 20.

Or, the driving member 30 may be an air cylinder, the air cylinder is mounted on the base 10, and the nozzle 20 is connected to a telescopic rod of the air cylinder so as to stretch along with the telescopic rod of the air cylinder, so that the nozzle 20 can be driven to move to the first position or the second position or the third position under the action of the air cylinder; for example, the air cylinder may move the nozzle 20 to a first position (may be a specific position or a range, for example, the first position may be a non-fixed range, and the nozzle 20 may move within the first position range to perform spray cleaning on the cleaning member 220); at this time, the nozzle 20 works to spray the liquid to clean the cleaning member 220; for another example, after cleaning the cleaning member 220 is completed, the nozzle 20 may be controlled to adjust to the second position (may be a specific position or a range, for example, the second position may be a non-fixed range, and the nozzle 20 may be moved within the second position range to perform liquid spraying cleaning on the bottom surface of the cleaning structure 50), where the nozzle 20 may operate to perform liquid spraying cleaning on the bottom surface of the cleaning structure 50; for example, after the cleaning structure 50 is cleaned, the nozzle 20 may be controlled to be adjusted to a third position (may be a specific position or a range, for example, the third position may be a non-fixed range, and the nozzle 20 may be moved within the third position range to perform liquid spraying cleaning on the sump 11), where the nozzle 20 may operate to clean the sump 11. Of course, the liquid spraying cleaning may be performed not in the above-described order, but the liquid spraying direction of the nozzle 20 may be controlled according to the cleaning requirement, for example, when the sewage tank 11 is cleaned, the nozzle 20 may be controlled to be always at the third position.

Further, in the embodiment of the present application, the driving member 30 may include a first driving system, a second driving system, and a third driving system, wherein the first driving system drives the at least one nozzle 20 to spray toward the cleaning member 220 of the cleaning robot 200, the second driving system drives the at least one nozzle 20 to spray toward the cleaning structure 50 for cleaning the cleaning member 220, and the third driving system drives the at least one nozzle 20 to spray toward the sump 11.
