[0038] like Figure 1 and Figure 2As shown, according to the implementation mode of the utility model, the first aspect of the utility model proposes a cleaning base station 100, the cleaning base station 100 includes a water tank 10, a cleaning disc 40 and an air pump 30, the water tank 10 includes a clean water chamber 11 and a sewage chamber 12, the cleaning disc 40 is connected to the clean water chamber 11 through a first pipeline 13, and the exhaust port of the air pump 30 is connected to the first pipeline 13 through a second pipeline 21.

[0039] It can be understood that the water tank 10 can be a box structure, that is, the water tank 10 can be formed by integral injection molding and form two cavities, namely the clean water chamber 11 and the sewage chamber 12. The clean water chamber 11 is used to hold clean water for the cleaning disc 40 to clean the cleaning components of the cleaning robot, such as the rag of the floor cleaning robot, and the sewage chamber 12 is used to hold the sewage after the cleaning disc 40 cleans. It can also be a structure with two water tanks, and the interiors of the two water tanks respectively define the clean water chamber 11 and the sewage chamber 12. The cleaning tray 40 is a tray-shaped structure and has a parking space for cleaning equipment, such as a floor-cleaning robot. The cleaning tray 40 is also provided with a plurality of cleaning parts, such as a scraper or a brush head, for cleaning the rag on the floor-cleaning robot by rotation or reciprocating motion. During cleaning, the water pump 20 extracts clean water from the clean water chamber 11 and drives the clean water into the cleaning tray 40 to spray and clean the rag. After cleaning, the air pump 30 evacuates the air in the closed sewage chamber 12, and then under the negative pressure of the sewage chamber 12, the sewage in the cleaning tray 40 is extracted into the sewage chamber 12 to complete the water change. The utility model connects the exhaust port of the air pump 30 with the clean water chamber 11 to the first pipeline 13 of the cleaning tray 40. When the air pump 30 is running, the extracted gas is discharged to the first pipeline 13 through the second pipeline 21 to discharge the water in the first pipeline 13 to the clean water tray, thereby reducing the phenomenon of water in the water channel being frozen and improving the reliability of the water channel.

[0040] The utility model connects the exhaust port of the air pump 30 to the clean water chamber 11 to connect the first pipeline 13 of the cleaning tray 40. After the cleaning tray works, a large amount of clean water remains in the first pipeline 13 due to the air pressure closure in the first pipeline 13. When the air pump 30 starts to work, the air exhausted by the air pump 30 enters the first pipeline 13 through the second pipeline 21, and the clean water in the first pipeline 13 is discharged to the cleaning tray 40, so as to reduce the phenomenon of freezing and cracking of the water channel when the temperature is low, and improve the reliability of the cleaning base station 100.

[0041] In some embodiments of the present invention, the cleaning base station further includes a third pipeline 31 , the third pipeline 31 connects the sewage chamber 12 and the cleaning plate 40 , and an air inlet of the air pump 30 connects the sewage chamber 12 .

[0042] It is understandable that the air inlet of the air pump 30 can be connected to the sewage chamber 12 through the fifth pipe 32. When the air pump 30 starts working, negative pressure is formed in the sewage chamber 12, and the sewage in the cleaning disc 40 enters the sewage chamber 12 through the third pipe 31 to clean the cleaning disc 40.

[0043] In some embodiments of the present invention, the cleaning base station 100 further includes a one-way valve 212 disposed on the second pipeline 21 , and the one-way conducting direction of the one-way valve 212 is from the air pump 30 to the first pipeline 13 .

[0044] It can be understood that a one-way valve 212 can be set on the second pipeline 21. The one-way valve 212 can be a spring-type one-way valve or a gravity-type one-way valve. By setting the one-way valve 212, the air pump 30 to the first pipeline 13 is unidirectionally connected, so that when the water pump 20 is running, the extracted clean water will not flow through the second pipeline 21 to the position of the air pump 30, thereby improving the reliability of the whole machine.

[0045] In some embodiments of the present invention, the one-way valve is a duckbill valve.

[0046] It can be understood that the duckbill valve is a rubber-billed check valve having a normally closed rubber duckbill. When the air pump 30 is running, the duckbill valve opens under the pressure of the air pump 30, allowing gas to enter the first pipeline 13 to discharge the clean water. When the air pump 30 is not running, the duckbill valve closes so that the clean water in the first pipeline 13 will not pass through the duckbill valve to the second pipeline 21, thereby protecting the air path from water ingress.

[0047] In some embodiments of the utility model, the first pipeline 13 includes a first pipe section and a second pipe section, and the cleaning base station 100 also includes a tee 23, the first interface of the tee 23 is connected to the clean water chamber 11 through the first pipe section, the second interface of the tee 23 is connected to the inlet of the cleaning disk 40 through the second pipe section, and the third interface of the tee 23 is connected to the exhaust port of the air pump 30 through the second pipeline 21.

[0048] It is understandable that the tee 23 can be a conventional tee 23, and the tee 23 can be threadedly connected to the first pipe section, the second pipe section and the third pipe 31 or fastened by a clamp.

Part of the second pipeline 21 can be arranged in a U-shape so that it has a water storage effect. In actual use, the water flowing from the first pipeline 13 can be stored in the water trap 211 to avoid affecting the air pump 30 and related air circuit parts, thereby improving the reliability of the whole machine.

[0051] In some embodiments of the present invention, the cleaning base station 100 further includes a water pump 20 , an inlet of the water pump 20 is connected to the clean water chamber 11 , and an outlet of the water pump 20 is connected to the cleaning tray 40 through a first pipeline 13 .

[0052] It can be understood that the water pump 20 can be set in the clean water chamber 11, or it can be set outside the water tank 10 and connected to the clean water chamber through the fourth pipe 22. By setting the water pump 20, the clean water in the clean water chamber 11 is transported to the cleaning tray 40 to clean the cleaning tray 40.

[0053] In some embodiments of the present invention, the water pump 20 and the air pump 30 are both disposed outside the water tank 10 .

[0054] It is understandable that mounting holes or clamping structures may be provided on the outer wall of the water tank 10 to install the water pump 20 and the air pump 30 , and pipeline fixing clamps may also be provided to fix the pipelines, reduce abnormal displacement of the pipelines, and improve the reliability of the cleaning base station 100 .

[0058] In some embodiments of the present invention, the water pump 20 is an electromagnetic pump.

[0059] It is understandable that the control device of the cleaning base station 100 is electrically connected to the water pump 20 so that water can be pumped automatically, thereby improving the intelligence of the cleaning base station 100.

[0060] In some embodiments of the present invention, along the vertical direction, the clean water tank 10 and the dirty water tank 10 are both located above the cleaning tray 40 .
