[0040] like Figure 1 As shown, a Cartesian coordinate system is established, and it is defined that the length direction of the cleaning device 1000 is parallel to the direction shown by the x-axis, and the height direction of the cleaning device 1000 is parallel to the direction shown by the z-axis. The length direction and height direction of the base station 2000 may be consistent with the length direction and height direction of the cleaning device 1000. It can be understood that the above definition is only for the convenience of understanding the relative position relationship of the various structures in the surface cleaning system, and should not be understood as a limitation to the present application.

[0041] like Figure 1 As shown, an embodiment provides a surface cleaning system, including a cleaning device 1000 and a base station 2000. The cleaning device 1000 can be used to provide a cleaning function for a surface to be cleaned, such as a floor, a desktop, or a window. Accordingly, the cleaning device 1000 can be a sweeper, a floor scrubber, a desktop cleaning robot, or a window cleaning robot. The base station 2000 can be used to recycle the sewage in the cleaning device 1000.

[0042] Of course, the base station 2000 can also provide functions such as charging and water supply for the cleaning device 1000.

[0043] like Figure 1 and Figure 2As shown, the cleaning device 1000 includes a cleaning device body 1100 and a sewage pipe 1200. Among them, the cleaning device 1000 may include a first shell 1110 and a sewage box (not shown) located in the first shell 1110. A connection groove 1111 that communicates with the external environment is configured on one side of the first shell 1110. In some embodiments, the connection groove 1111 can be formed by a side wall of the first shell 1110 being recessed into the interior of the first shell 1110.

[0044] The sewage pipe 1200 is fixedly mounted on the first housing 1110. One end of the sewage pipe 1200 extends to the interior of the first housing 1110 and can be connected to the sewage box through a connecting pipe (not shown) and other structures. The other end of the sewage pipe 1200 is inserted into the wall plate of the connecting groove 1111 and is connected to the connecting groove 1111. In some embodiments, the end of the sewage pipe 1200 away from the sewage box can protrude relative to the inner side of the wall plate of the connecting groove 1111. Among them, the inner side of the wall plate of the connecting groove 1111 can refer to the side of the wall plate close to the external environment, that is, the side away from the internal environment of the first housing 1110.

[0045] Combined with Figure 3 and Figure 4 The base station 2000 includes a base station body 2100 and a transfer tube 2200. The base station body 2100 may include a second shell 2110 and a sewage tank 2120 located inside the second shell 2110. The transfer tube 2200 is installed in a floating manner on one side of the second shell 2110. One end of the transfer tube 2200 extends into the second shell 2110 and is connected to the sewage tank 2120. The other end of the transfer tube 2200 away from the sewage tank 2120 is used to plug into the connection groove 1111 and is connected to the end of the sewage pipe 1200 away from the sewage box. The floating direction of the transfer tube 2200 is parallel to the plug-in direction of the transfer tube 2200. In some embodiments, the floating direction of the transfer tube 2200 may be parallel to the length direction of the base station 2000.

[0046] In the embodiment, the adapter tube 2200 is installed in a floating manner on the second housing 2110, and the floating direction of the adapter tube 2200 is parallel to the plugging direction of the adapter tube 2200. When the cleaning device 1000 enters the base station 2000, the adapter tube 2200 is inserted into the connection groove 1111, and the adapter tube 2200 can move along the plugging direction to achieve a soft connection between the adapter tube 2200 and the cleaning device 1000, thereby avoiding a rigid collision between the cleaning device 1000 and the adapter tube 2200, thereby reducing the possibility of damage to the cleaning device 1000 and the base station 2000, protecting the cleaning device 1000 and the base station 2000, and extending their service life.

[0047] like Figures 1 to 5As shown, in some embodiments, the transfer tube 2200 may be roughly in the shape of an inverted L. The transfer tube 2200 includes a first structural segment 2210 and a second structural segment 2220 that are perpendicular to each other, and the first structural segment 2210 and the second structural segment 2220 are an integral structure. The transfer tube 2200 is configured with a water receiving trough that passes through the first structural segment 2210 and the second structural segment 2220.

[0048] The first structural section 2210 may be parallel to the height direction of the base station 2000. The first structural section 2210 is located inside the second housing 2110 and is connected to the sewage tank 2120. Specifically, the first structural section 2210 is provided with a first water outlet 2211 at one end away from the second structural section 2220. The first water outlet 2211 may be arranged toward the sewage tank 2120 and located above the gravity direction of the sewage tank 2120 to achieve the connection between the transfer tube 2200 and the sewage tank 2120. When the sewage flows out from the first water outlet 2211 of the transfer tube 2200, it may fall into the sewage tank 2120. It can be understood that the sewage tank 2120 is provided with an opening structure opposite to the first water outlet 2211 at one end facing the first structural section 2210, so that the sewage can smoothly enter the sewage tank 2120.

[0049] The second structural section 2220 is inserted into the second shell 2110 and can slide relative to the second shell 2110. One end of the second structural section 2220 away from the first structural section 2210 protrudes relative to the outer side of the second shell 2110 and can be used to plug into the connecting groove 1111. A water inlet 2221 is arranged on one side of the second structural section 2220, and the water inlet 2221 can be relatively located on the outer side of the second shell 2110. When the second structural section 2220 is inserted into the connecting groove 1111, the water inlet 2221 can be opposite to the second water outlet 1210 of the sewage pipe 1200, and the water inlet 2221 can be located below the second water outlet 1210 in the direction of gravity, so that the sewage in the sewage pipe 1200 can smoothly flow into the transfer pipe 2200 and enter the sewage tank 2120 through the transfer pipe 2200.

[0050] In some embodiments, the area of ​​the water inlet 2221 is much larger than the area of ​​the second water outlet 1210, so that the second water outlet 1210 can be easily connected to the water inlet 2221, allowing a certain movement error when the cleaning equipment 1000 enters the base station 2000, ensuring that the sewage output from the second water outlet 1210 can smoothly enter the water inlet 2221, reducing the possibility of sewage spilling.

[0051] like Figure 2 and Figure 5As shown, in some embodiments, the second structural section 2220 includes a bottom plate 2222 opposite to the water inlet 2221. The bottom plate 2222 can be gradually inclined in a direction away from the water inlet 2221 from one end away from the first structural section 2210 to one end close to the first structural section 2210. Thus, the bottom plate 2222 can drain the sewage entering the second structural section 2220, and the sewage can flow in a relatively low position in the bottom plate 2222 under the action of gravity, so that the sewage enters the first structural section 2210 and enters the sewage tank 2120 as much as possible, reducing the residual sewage in the transfer pipe 2200, thereby reducing the probability of scaling and clogging of the transfer pipe 2200.

[0052] like Figure 2 , Figures 4 to 6 As shown, the adapter tube 2200 further includes an adapter frame 2230, which can be disposed around the second structural section 2220 and located inside the second housing 2110. In an embodiment, the adapter frame 2230 and the second structural section 2220 can be an integral structure.

[0053] In other embodiments, the adapter frame 2230 may also be fixedly connected to the second structural segment 2220 by means of snap connection or gluing.

[0054] In the embodiment, the base station 2000 further includes a mounting bracket 2300 and an elastic member 2400 , and the adapter tube 2200 can be floatingly mounted on the second housing 2110 via the mounting bracket 2300 and the elastic member 2400 .

[0055] In some embodiments, the mounting bracket 2300 can be fixedly mounted on the inner side of the second housing 2110 by screw connection or the like, and is arranged around the circumference of the second structural segment 2220. That is, the second structural segment 2220 is passed through the mounting bracket 2300 and can slide relative to the mounting bracket 2300. In an embodiment, the mounting bracket 2300 can be located on a side of the adapter frame 2230 close to the first structural segment 2210.

[0056] The elastic member 2400 can abut between the mounting bracket 2300 and the adapter frame 2230. When the adapter tube 2200 is not squeezed by the cleaning device 1000, the elastic member 2400 can be in a compressed or naturally stretched state, and at the same time, the side of the adapter frame 2230 away from the mounting bracket 2300 can abut against the inner wall of the second housing 2110.

[0057] When the adapter tube 2200 is inserted into the connection slot 1111 of the cleaning device 1000 and abuts against the wall of the connection slot 1111, the adapter tube 2200 can be retracted into the second housing 2110, and at the same time, the elastic member 2400 can be compressed and store elastic potential energy under the squeezing action of the adapter frame 2230. When the cleaning device 1000 is separated from the base station 2000, the adapter tube 2200 is no longer subjected to the force of the cleaning device 1000, and the adapter tube 2200 can be extended to the outside of the second housing 2110 and reset under the elastic force of the elastic member 2400.

[0058] In other embodiments, one end of the elastic member 2400 may be connected to the adapter frame 2230, and the other end of the elastic member 2400 may be connected to a portion of the inner wall of the second shell 2110 that is opposite to the adapter frame 2230. When the adapter tube 2200 is not squeezed by the cleaning device 1000, the elastic member 2400 may be in a stretched state or a naturally elongated state, and a protrusion is protruded from one side of the adapter frame 2230 that is close to the inner wall of the second shell 2110 and abuts against the inner wall of the second shell 2110.

[0059] In some embodiments, the elastic member 2400 may be a spring.

[0060] In other embodiments, the elastic member 2400 may also be a spring sheet or a flexible column.

[0061] like Figure 5 and Figure 6 As shown, the base station 2000 also includes a guide rod 2500. One end of the guide rod 2500 can be fixedly connected to the adapter frame 2230 by means of screwing, bonding or clamping. The other end of the guide rod 2500 can be slidably penetrated into the mounting bracket 2300, and the elastic member 2400 can be sleeved on the guide rod 2500. In the embodiment, the guide rod 2500 can provide a guiding function for the floating of the adapter tube 2200, reduce the possibility of the adapter tube 2200 being skewed, and thereby reduce the probability of the adapter tube 2200 being stuck or stuck during the floating process. At the same time, the guide rod 2500 can provide radial limiting for the elastic member 2400 to prevent the elastic member 2400 from being skewed, so as to ensure that the elastic member 2400 provides a stable and reliable elastic force for the adapter frame 2230, and also extend the service life of the elastic member 2400.

[0062] In other embodiments, a limit block is provided on one side of the guide rod 2500 away from the adapter frame 2230, and the limit block may be provided along the radial protrusion of the guide rod 2500. In addition, the limit block may be located on one side of the mounting bracket 2300 away from the adapter frame 2230, and may be used to limit the stroke of the adapter tube 2200 extending relative to the second housing 2110.

[0063] In some embodiments, a limiting groove 2231 is further configured on one side of the adapter frame 2230 close to the mounting bracket 2300, and one end of the elastic member 2400 close to the adapter frame 2230 can be limited in the limiting groove 2231 to achieve further radial limitation and reduce the possibility of the elastic member 2400 being skewed.

[0064] like Figure 2 and Figure 4 As shown, in some embodiments, the connection groove 1111 includes an open end 1111c, a groove bottom 1111a and a side wall 1111b, wherein the groove bottom 1111a and the side wall 1111b may constitute a wall plate of the connection groove 1111. In some embodiments, the sewage pipe 1200 may be passed through the side wall 1111b and protrude relative to the side of the side wall 1111b close to the external environment. In an embodiment, the transfer pipe 2200 may be inserted into the connection groove 1111 through the open end 1111c. The groove bottom 1111a may be opposite to the open end 1111c, and the side wall 1111b may extend from the open end 1111c to the groove bottom 1111a.

[0065] In some embodiments, the side wall 1111b may be gradually inclined toward the direction close to the central axis L of the connection groove 1111 from the end close to the opening end 1111c to the end close to the groove bottom 1111a. Thus, the adapter tube 2200 can be conveniently plugged into the connection groove 1111, and the accuracy of the alignment plugging of the adapter tube 2200 and the connection groove 1111 can be improved. At the same time, the side wall 1111b can guide the adapter tube 2200 so as to be plugged into place.

[0066] like Figure 3 and Figure 4 As shown, the base station 2000 further includes a trigger member 2600, which is disposed at one end of the transfer tube 2200 for rubbing the connection groove 1111. In some embodiments, an end of the second structural segment 2220 away from the first structural segment 2210 is provided with an assembly groove 2212, and the opening structure of the assembly groove 2212 is arranged opposite to the water inlet 2221. The trigger member 2600 can be fixedly installed in the assembly groove 2212 by means of clamping or bonding.

[0067] Combined with Figure 7 The cleaning device 1000 further includes a sensing member 1300 that cooperates with the trigger member 2600. The sensing member 1300 may be fixedly disposed in the first housing 1110 and disposed close to the bottom 1111a of the connecting groove 1111. In the embodiment, the sensing member 1300 may be electrically connected to the main control board 1120 in the cleaning device body 1100.

[0068] During the process of the cleaning device 1000 entering the base station 2000, one end of the transfer tube 2200 provided with the trigger 2500 is gradually inserted into the connection groove 1111 and gradually approaches the sensing member 1300. When the sensing member 1300 senses the trigger member 2600, a corresponding sensing signal can be generated and sent to the main control board 1120. When receiving the sensing signal, the main control board 1120 can control the sewage pump 1130 in the cleaning device body 1100 to discharge the sewage in the sewage box, and output it to the transfer tube 2200 through the sewage pipe 1200, and then enter the sewage tank 2120 of the base station 2000 through the transfer tube 2200. It can be understood that when the sensing member 1300 senses the trigger member 2600, it can indicate that the second water outlet 1210 is opposite to the water inlet 2221, and the cleaning device 1000 can successfully transport the sewage to the base station 2000.

[0069] In some embodiments, the triggering member 2600 may be a magnet, and the sensing member 1300 may be a Hall sensor.

[0070] In other embodiments, the sensing element 1300 may also be a reed switch.

[0071] In other embodiments, the trigger member 2600 may also be a magnetic member such as an electromagnet.

[0072] In the related art, the sewage pipe 1200 and the transfer pipe 2200 are aligned and detected by aligning the cleaning device 1000 with the charging terminals in the base station 2000. However, in order to ensure that the cleaning device 1000 is accurately electrically connected to the base station 2000, its charging terminal will be set relatively long. In this way, when the cleaning device 1000 enters the base station 2000, it is not necessarily centered with the base station 2000. The cleaning device 1000 may have a certain deviation or skew, resulting in a relatively large error in the alignment of the second water outlet 1210 and the water inlet 2221, which can easily lead to the misdischarge of sewage.

[0073] In the embodiment, by setting the trigger member 2600 and the sensor member 1300, accurate alignment detection of the transfer tube 2200 and the connecting groove 1111 can be achieved, and then accurate alignment detection of the water inlet 2221 of the transfer tube 2200 and the second water outlet 1210 can be achieved, thereby improving the accuracy of the alignment detection and reducing the possibility of accidental discharge of sewage.
