The direction opposite to the arrow along the front-to-back axis X, that is, the direction in which the automatic cleaning device enters the self-cleaning maintenance station, is marked as "backward", and the direction along the arrow along the front-to-back axis X, that is, the direction in which the automatic cleaning device leaves the self-cleaning maintenance station, is marked as "forward". The transverse axis Y is essentially along the direction of the width of the self-cleaning maintenance station body. The direction of the arrow along the transverse axis Y is the "left side" of the self-cleaning maintenance station, and the opposite direction of the arrow along the transverse axis Y is the "right side" of the self-cleaning maintenance station. The vertical axis Z is the direction extending upward along the bottom surface of the self-cleaning maintenance station. The direction of the arrow along the vertical axis Z is the "upper side" of the self-cleaning maintenance station, and the opposite direction of the arrow along the vertical axis Z is the "lower side" of the self-cleaning maintenance station.

[0058] like Figure 1 , Figure 2 As shown, the self-cleaning maintenance station provided in this embodiment includes a self-cleaning maintenance station bottom plate 1000 and a self-cleaning maintenance station body 2000, wherein the self-cleaning maintenance station bottom plate 1000 and the self-cleaning maintenance station body 2000 are detachably or non-detachably connected, and the detachable connection facilitates the transportation and maintenance of the self-cleaning maintenance station bottom plate 1000 and the self-cleaning maintenance station body 2000.

[0059] like Figure 1 , Figure 2As shown, the maintenance station body 2000 includes a clean water pipe assembly 2100, a sewage pipe assembly 2200 and a water pipe groove 2300. The clean water pipe assembly 2100 is connected to the clean water tank 3000 and is configured to inject clean water into the clean water tank 3000; the sewage pipe assembly 2200 is connected to the sewage tank 4000 and is configured to export sewage from the sewage tank 4000; the water pipe groove 2300 is arranged at one end of the maintenance station body 2000 near the bottom, and the water pipe groove 2300 is roughly along the maintenance station body 2000. The station body 2000 extends in the left-right direction and is configured to accommodate at least a portion of the clean water pipe assembly 2100 and / or at least a portion of the sewage pipe assembly 2200. The water pipe groove 2300 can only accommodate at least a portion of the clean water pipe assembly 2100, or only accommodate at least a portion of the sewage pipe assembly 2200. After the water pipe groove 2300 is widened, it can accommodate at least a portion of the clean water pipe assembly 2100 and at least a portion of the sewage pipe assembly 2200 at the same time. At least a portion of the clean water pipe assembly 2100 and / or at least a portion of the sewage pipe assembly 2200 is located behind the water pipe groove 2300, and the projections of the clean water pipe assembly 2100 and the sewage pipe assembly 2200 on the horizontal plane do not exceed the projection of the maintenance station body 2000 on the horizontal plane, so that at least a portion of the clean water pipe assembly 2100 and / or at least a portion of the sewage pipe assembly 2200 are completely hidden in the water pipe groove 2300, making the appearance of the self-cleaning maintenance station more neat.

[0060] In some embodiments, Figure 1 As shown, the maintenance station body 2000 also includes a back panel 2400, which is detachably arranged on the back side of the maintenance station body 2000, and the lower edge of the back panel 2400 extends to the upper edge of the water pipe groove 2300, so that the water pipe groove 2300 is exposed to the outside of the self-cleaning maintenance station, which is convenient for manual storage of at least a portion of the clean water pipe assembly 2100 and / or at least a portion of the sewage pipe assembly 2200. Optionally, both ends of the water pipe groove 2300 have a wider size to accommodate the first clean water pipe joint 2110 and the first sewage pipe joint 2210.

[0061] In some embodiments, Figure 1 As shown, the maintenance station body 2000 also includes at least one locking member 2310, which is located at the upper edge or the lower edge of the water pipe groove 2300, and is used to lock at least a portion of the clean water pipe assembly and / or at least a portion of the sewage pipe assembly, for example, to lock the first clean water pipe 2120 and / or the first sewage pipe 2220 to prevent the first clean water pipe 2120 and / or the first sewage pipe 2220 from falling off from the water pipe groove 2300.

[0062] In some embodiments, Figure 2As shown, the clean water pipe assembly 2100 includes a clean water pipe first joint 2110, which is disposed at one end of the water pipe groove 2300 adjacent to the clean water tank 3000; the sewage pipe assembly 2200 includes a sewage pipe first joint 2210, which is disposed at one end of the water pipe groove 2300 adjacent to the sewage tank 4000; wherein the water inlet of the clean water pipe first joint 2110 and the water outlet of the sewage pipe first joint 2210 are oriented in the same or opposite directions. In some embodiments, the clean water pipe first joint 2110 and the sewage pipe first joint 2210 are located at one end of the water pipe groove 2300 and can rotate in the horizontal direction. Exemplarily, the water inlet of the first joint 2110 of the clean water pipe can be set to the left or right, and the water outlet of the first joint 2210 of the sewage pipe can also be set to the left or right. Accordingly, the first clean water pipe 2120 connected to the water inlet of the first joint 2110 of the clean water pipe can be snapped into the water pipe groove 2300, or rotated to another direction and not located in the water pipe groove 2300. Similarly, the first sewage pipe 2220 connected to the water outlet of the first joint 2210 of the sewage pipe can be snapped into the water pipe groove 2300, or rotated to another direction and not located in the water pipe groove 2300. This makes it convenient to reasonably arrange the positions of the first clean water pipe 2120 and the first sewage pipe 2220 according to the water inlet and sewage discharge positions.

[0063] In some embodiments, Figure 2 As shown, the clean water pipe assembly 2100 further includes a first clean water pipe 2120, which is connected to the clean water pipe first joint 2110; the sewage pipe assembly 2200 further includes a first sewage pipe 2220, which is connected to the sewage pipe first joint 2210; the first clean water pipe 2120 and / or the first sewage pipe 2220 are clamped in the water pipe groove 2300. That is, only the first clean water pipe 2120 can be clamped in the water pipe groove 2300, or only the first sewage pipe 2220 can be clamped in the water pipe groove 2300, or the first clean water pipe 2120 and the first sewage pipe 2220 can be clamped in the water pipe groove 2300 at the same time, so that the positions of the first clean water pipe 2120 and the first sewage pipe 2220 can be reasonably arranged according to the water inlet and sewage discharge positions. The diameter of the first sewage pipe 2220 should be larger than that of the first clean water pipe 2120, because the first sewage pipe 2220 needs to output sewage to prevent garbage in the sewage from being stuck in the first sewage pipe 2220. Optionally, the first sewage pipe 2220 and the first clean water pipe 2120 are formed of hard materials.

[0064] In some embodiments, Figure 2As shown, the clean water pipe assembly 2100 further includes a clean water pipe second joint 2130, which is disposed at the top of the maintenance station body 2000; a water inlet solenoid valve 2140, which is disposed between the clean water pipe second joint 2130 and the clean water tank 3000, and one end of the clean water pipe second joint 2130 extends into the water inlet solenoid valve 2140 and communicates with the water inlet solenoid valve 2140; and a second clean water pipe 2150, which is connected between the clean water pipe first joint 2110 and the clean water pipe second joint 2130, and is disposed approximately along the vertical direction at the edge or corner of the maintenance station body 2000. The second clean water pipe 2150 is formed of a hard material so as to be disposed in the vertical direction without being easily bent.

[0065] In some embodiments, the maintenance station body 2000 further includes a stopper 2160, which is disposed on the inner side wall of the outer shell of the maintenance station body 2000 and abuts against the outer end of the second clean water pipe joint 2130, and the stopper 2160 is configured to apply an external force toward the water inlet solenoid valve 2140 to the second clean water pipe joint 2130 to prevent the second clean water pipe joint 2130 from being separated from the water inlet solenoid valve 2140 due to the water pressure after the water inlet solenoid valve 2140 is closed. Optionally, there is an assembly gap between the stopper 2160 and the second clean water pipe joint 2130.

[0066] In some embodiments, Figure 4 As shown, the clean water pipe assembly 2100 also includes a third clean water pipe joint 2170, which is connected to the first clean water pipe joint 2110 and is used to change the direction of water flow, such as changing the horizontal water flow into the vertical water flow; the clean water pipe assembly 2100 also includes a positioning member 2180, which is arranged on the outside of the third clean water pipe joint 2170, for example, fixed by at least one screw, and the positioning member 2180 is used to fix the third clean water pipe joint 2170 to prevent the third clean water pipe joint 2170 from being separated from the first clean water pipe joint 2110 under water pressure.

[0067] In some embodiments, Figure 1 and Figure 5As shown, the sewage pipe assembly 2200 further includes a sewage pipe second joint 2230, which is arranged at the top of the maintenance station body and communicates with the sewage tank 4000, and can be a water outlet joint of the sewage tank 4000; a water diversion pipe 2240, which is, for example, a Y-shaped structure, and has a first water inlet, a second water inlet and a water outlet, and the water outlet is connected to the sewage pipe first joint 2210; a second sewage pipe 2240, which is arranged between the first water inlet and the sewage pipe second joint 2230. The sewage pipe assembly 2200 further includes a third sewage pipe 2250, which is arranged between the second water inlet and the overflow port of the sewage tank 4000. The sewage in the sewage tank 4000 is discharged through the sewage pipe second joint 2230, the second sewage pipe 2240, the sewage pipe first joint 2210, and the first sewage pipe 2220. In addition, when the sewage tank 4000 is full of water, pumping water into the sewage tank 4000 may not stop due to failure of the float valve or other reasons. At this time, excessive sewage can be discharged from the overflow port of the sewage tank 4000, and then the sewage in the third sewage pipe 2250 and the second sewage pipe 2240 is collected in the diversion pipe 2260 and discharged through the first sewage pipe 2220, thereby preventing sewage from overflowing into the self-cleaning maintenance station and causing damage to other components of the self-cleaning maintenance station.

[0068] In some embodiments, Figure 5 As shown, the sewage pipe assembly 2200 also includes a duckbill valve 2270, which is arranged at the overflow outlet of the sewage tank 4000 to prevent sewage backflow. The outlet of the duckbill valve 2270 is usually a one-way flat-mouth structure. When water flows into the inlet of the duckbill valve 2270, it will break through the flat-mouth structure of the outlet and flow out.

[0069] The disclosed embodiment also provides a maintenance system, including an automatic cleaning device and any of the self-cleaning maintenance stations described above.
