Users need to periodically remove these tanks to empty the wastewater, but water can easily accumulate inside, leading to bacterial growth. Furthermore, most of the industry's wastewater pumps do not have a designated outlet, directly venting the contaminated air from the wastewater tank into the base station, which may damage the base station's electrical system. Utility Model Content

[0003] Therefore, it is necessary to provide a base station and cleaning system to address the above problems.

[0004] The technical solution is as follows:

[0005] On the one hand, a base station is provided, including:

The exhaust resistance of the first pipe section is greater than the exhaust resistance of the second pipe section.

[0011] The technical solution will be further explained below:

[0012] In one embodiment, the first pipeline segment is located above the second pipeline segment, and the length of the first pipeline segment is greater than the length of the second pipeline segment.

[0013] In one embodiment, the drainage pipeline includes a first connecting pipe with one end connected to the drain outlet, a second connecting pipe with one end connected to the sludge collection tank, and a first connecting member. The first connecting member has a first end, a second end, and a third end that are connected to each other. The first end is connected to the other end of the first connecting pipe, the second end is connected to the other end of the second connecting pipe, and the third end is connected to the air outlet.

[0014] In one embodiment, the sludge collection tank includes a tank body communicating with the sludge inlet and a discharge connector installed on the top of the tank body. One end of the discharge connector is connected to the end of the second connecting pipe away from the first connecting member, and the other end extends to the top of the tank body so that the tank body can collect the water discharged from the discharge connector.

[0015] In one embodiment, the base station further includes an air extraction pipe and an air exhaust pipe, the two ends of the air extraction pipe being connected to the air extraction port and the air inlet, respectively, and the two ends of the air exhaust pipe being connected to the air outlet and the third end, respectively.

[0016] In one embodiment, the mounting cavity is further provided with a baffle plate, which divides the mounting cavity into a first mounting chamber for installing the sewage tank and a second mounting chamber for installing the clean water tank. The bottom walls of the first mounting chamber and the second mounting chamber are provided with the drain outlets. The drain pipe further includes a third connecting pipe, a fourth connecting pipe and a second connecting member. One end of the third connecting pipe and one end of the fourth connecting pipe are respectively connected to the two drain outlets. The second connecting member is provided with a fourth end, a fifth end and a sixth end that are interconnected. The fourth end is connected to the other end of the third connecting pipe, the fifth end is connected to the other end of the fourth connecting pipe, and the sixth end is connected to the end of the first connecting pipe away from the first connecting member.

[0017] In one embodiment, the first connecting pipe is located above the second connecting pipe, and the third and fourth connecting pipes are both located above the first connecting pipe.

[0018] In one embodiment, the mounting cavity is further provided with a baffle plate, which divides the mounting cavity into a first mounting chamber for installing the sewage tank and a second mounting chamber for installing the clean water tank. The bottom walls of the first mounting chamber and the second mounting chamber are both provided with the drain outlets.

[0021] In the base station and cleaning system described in the above embodiments, when water accumulates in the installation cavity, it flows through the drain outlet to the drain pipe for drainage. When the air pump operates, it draws air from the wastewater tank through the air inlet and outlet, and exhausts air into the drain pipe through the air outlet. Because the exhaust resistance of the first pipe section is greater than that of the second pipe section, the polluted gas in the drain pipe will flow along the second pipe section from the sludge collection tank to the outside of the base station, preventing polluted gas from entering the base station and causing damage to the internal circuitry, thus improving the reliability of the base station. In addition, the flow of polluted gas in the second pipe section creates a negative pressure, allowing all the water in the installation cavity and drain pipe to be discharged into the sludge collection tank under this negative pressure, ensuring that the installation cavity and drain pipe remain dry, preventing bacterial growth, and improving the cleanliness of the base station.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In one embodiment, a cleaning system is provided, including a cleaning device and a base station 10. The base station 10 has a working position and is configured to collect wastewater discharged by the cleaning device and replenish water to the cleaning device when the cleaning device moves to the working position. Thus, the base station 10 can store wastewater from the cleaning device and provide clean water to the cleaning device, enabling the cleaning device to have continuous cleaning capabilities and improving the practicality of the cleaning system.

[0035] The cleaning equipment can be a sweeper, a floor scrubber, or other cleaning machines.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, a base station 10 is provided, including an installation body 100, a sludge collection tank 200, a drainage pipe 300, and an air pump 400. The installation body 100 has an installation cavity 110 and an air extraction port 120 and a sludge extraction port 130 communicating with the installation cavity 110. A drainage port 140 is provided on the bottom wall of the installation cavity 110. Both the air extraction port 120 and the sludge extraction port 130 are configured to communicate with a sludge tank 500 when the sludge tank 500 is installed in the installation cavity 110. The sludge collection tank 200 communicates with the sludge extraction port 130 and is used to collect sludge discharged from cleaning equipment. The drainage pipe 300 connects the drainage port 140 to the sludge collection tank 200. The air pump 400 has an air inlet and an air outlet; the air inlet communicates with the air extraction port 120, and the air outlet communicates with the drainage pipe 300. The drainage pipe 300 between the air outlet and the drain outlet 140 is set as the first pipe section, and the drainage pipe 300 between the air outlet and the sludge collection tank 200 is set as the second pipe section. The exhaust resistance of the first pipe section is greater than that of the second pipe section.

[0037] In the above embodiment, when water accumulates in the mounting cavity 110, the water can flow through the drain outlet 140 to the drain pipe 300, thus discharging the water. When the air pump 400 operates, it draws air from the sewage tank 500 through the air inlet and the air outlet 120, and exhausts air into the drain pipe 300 through the air outlet. Since the exhaust resistance of the first pipe section is greater than that of the second pipe section, the polluted gas in the drain pipe 300 will be discharged from the sewage collection tank 200 to the outside of the base station 10 along the second pipe section, preventing polluted gas from being discharged into the base station 10 and causing damage to the internal circuits of the base station 10, thereby improving the reliability of the base station 10. In addition, the foul gas will form a negative pressure during the flow of the second pipeline section, and the water in the installation cavity 110 and the drainage pipe 300 can be discharged into the dirt collection tank 200 under the action of the negative pressure, so as to keep the installation cavity 110 and the drainage pipe 300 dry, avoid the growth of bacteria, and improve the cleanliness of the base station 10.

[0038] Specifically, in this embodiment, the drain outlet 140 is connected to the lowest point of the bottom of the mounting cavity 110. The drain pipe 300 is located between the mounting body 100 and the sludge collection tank 200. The base station 10 also includes a sludge suction pipe 730, the two ends of which are respectively connected to the sludge suction outlet 130 and the sludge collection tank 200.

[0039] Optionally, the first pipe section is located above the second pipe section, and the length of the first pipe section is greater than the length of the second pipe section. In this way, the first pipe section is longer and the exhaust direction is upward, resulting in greater resistance for the suction pump 400 when exhausting gas through the first pipe section; while the second pipe section is shorter and the exhaust direction is downward, resulting in less resistance for the suction pump 400 when exhausting gas through the second pipe section. This ensures that the polluted gas discharged by the suction pump 400 is discharged along the second pipe section, improving the reliability of the base station 10.

[0040] It should be noted that, in this embodiment, the base station 10, as verified by experiments, can effectively discharge the polluted gas discharged by the air pump 400 along the second pipeline section.

[0041] like Figure 2 As shown, in one embodiment, the drainage pipe 300 includes a first connecting pipe 310 with one end connected to the drain outlet 140, a second connecting pipe 320 with one end connected to the sludge collection tank 200, and a first connector 330. The first connector 330 has a first end, a second end, and a third end that are interconnected. The first end is connected to the other end of the first connecting pipe 310, the second end is connected to the other end of the second connecting pipe 320, and the third end is connected to the vent. This improves the ease of assembly of the base station 10.

[0042] The first connector 330 can be configured as a three-way connector, a solenoid three-way valve, or other connection structures.

[0043] like Figure 2 , Figure 4 and Figure 5 As shown, optionally, the sludge collection tank 200 includes a tank body 210 communicating with the sludge suction port 130, and a discharge connector 220 installed on the top of the tank body 210. One end of the discharge connector 220 is connected to the end of the second connecting pipe 320 away from the first connecting member 330, and the other end extends above the tank body 210 so that the tank body 210 can collect the accumulated water discharged from the discharge connector 220. In this way, the relative position between the discharge connector 220 and the tank body 210 can remain stable, ensuring that all the accumulated water discharged from the discharge connector 220 will fall into the tank body 210, thereby improving the reliability of the base station 10.

[0044] Specifically, in this embodiment, the sludge collection tank 200 further includes a mounting bracket 230, which can be installed on the top of one side of the tank body 210 by snap-fit, screw-fit, plug-in, or other means. The mounting bracket 230 can be integrally formed with the discharge connector 220.

[0045] like Figure 2As shown, optionally, the base station 10 also includes an extraction pipe 710 and an exhaust pipe 720. The two ends of the extraction pipe 710 are connected to the extraction port 120 and the air inlet, respectively, and the two ends of the exhaust pipe 720 are connected to the air outlet and the third end, respectively. In this way, the extraction pump 400 is connected to the mounting body 100 through the extraction pipe 710 and to the drainage pipe 300 through the exhaust pipe 720, which allows the position of the extraction pump 400 inside the base station 10 to be flexibly adjusted, while also improving the assembly convenience of the base station 10.

[0046] like Figure 1 , Figure 6 and Figure 7 As shown, in one embodiment, a baffle 150 is also provided inside the mounting cavity 110, dividing the mounting cavity 110 into a first mounting chamber 111 for mounting a sewage tank 500 and a second mounting chamber 112 for mounting a clean water tank 600. Both the bottom walls of the first mounting chamber 111 and the second mounting chamber 112 are provided with drain outlets 140. The drainage pipe 300 also includes a third connecting pipe 340, a fourth connecting pipe 350, and a second connecting member 360. One end of the third connecting pipe 340 and one end of the fourth connecting pipe 350 are respectively connected to the two drain outlets 140. The second connecting member 360 has a fourth end, a fifth end, and a sixth end that are interconnected. The fourth end is connected to the other end of the third connecting pipe 340, the fifth end is connected to the other end of the fourth connecting pipe 350, and the sixth end is connected to the end of the first connecting pipe 310 away from the first connecting member 330. In this way, the water accumulated in the first installation chamber 111 and the second installation chamber 112 can be discharged into the sludge collection tank 200 through the corresponding drain outlet 140 and drain pipe 300, thereby improving the practicality of the base station 10.

[0047] The second connector 360 can be configured as a three-way connector, a solenoid three-way valve, or other connection structures.

[0048] Specifically, in this embodiment, the mounting body 100, air extraction port 120, sewage extraction port 130, drain port 140, and baffle plate 150 can all be integrally formed. The mounting body 100 also has a water extraction port communicating with the mounting cavity 110. The water extraction port is configured to communicate with the clean water tank 600 when the clean water tank 600 is installed in the second mounting chamber 112. The base station 10 also includes a water extraction pipe communicating with the water extraction port. The water extraction pipe is configured to communicate with the cleaning equipment when the cleaning equipment is moved to the working position, so as to deliver water to the cleaning equipment.

[0049] like Figure 2As shown, optionally, the first connecting pipe 310 is located above the second connecting pipe 320. The third connecting pipe 340 and the fourth connecting pipe 350 are both located above the first connecting pipe 310. In this way, the exhaust direction of the first connecting pipe 310, the third connecting pipe 340 and the fourth connecting pipe 350 is upward, which further increases the resistance encountered by the polluted gas when flowing in the first pipe section, ensuring that the polluted gas is discharged through the second pipe section and improving the reliability of the base station 10.

[0050] The first connecting pipe 310, the second connecting pipe 320, the third connecting pipe 340, the fourth connecting pipe 350, the air extraction pipe 710, the exhaust pipe 720, and the sewage extraction pipe 730 can all be made of flexible materials. For example, the first connecting pipe 310, the second connecting pipe 320, the third connecting pipe 340, the fourth connecting pipe 350, the air extraction pipe 710, the exhaust pipe 720, and the sewage extraction pipe 730 can all be made of flexible pipes such as silicone tubes.

[0051] Specifically, in this embodiment, the drainage pipe 300 has two first pipe sections and one second pipe section. The first connector 330, the first connecting pipe 310, the second connector 360, and the third connecting pipe 340 are sequentially connected to form one first pipe section. The first connector 330, the first connecting pipe 310, the second connector 360, and the fourth connecting pipe 350 are sequentially connected to form another first pipe section. The first connector 330 and the second connecting pipe 320 are connected to form a second pipe section.

[0052] In one embodiment, the mounting cavity 110 is further provided with a baffle 150, which divides the mounting cavity 110 into a first mounting chamber 111 for installing a sewage tank 500 and a second mounting chamber 112 for installing a clean water tank 600. Both the bottom walls of the first mounting chamber 111 and the second mounting chamber 112 are provided with drain outlets 140. The first connector 330 is also provided with a seventh end communicating with the first end, and the drain pipe 300 further includes a fifth connecting pipe with one end communicating with the seventh end. The end of the fifth connecting pipe away from the first connector 330 and the end of the first connecting pipe 310 away from the first connector 330 are respectively connected to the two drain outlets 140.

[0053] In this specific embodiment, the first end, the second end, the third end, and the seventh end are interconnected.

[0054] Optionally, the first connector 330 can be configured as a four-way structure. In this way, one four-way structure can be used instead of two three-way structures to achieve interconnection between the first connecting pipe 310, the second connecting pipe 320, the fifth connecting pipe and the exhaust pipe 720, thereby reducing the production cost of the base station 10.

[0055] Specifically, in this embodiment, the drainage pipe 300 has two first pipe sections and one second pipe section. The first connector 330 communicates with the first connecting pipe 310 to form one first pipe section. The first connector 330 communicates with the fifth connecting pipe to form another first pipe section. The first connector 330 communicates with the second connecting pipe 320 to form a second pipe section.

[0056] In one embodiment, a partition 150 is further provided within the mounting cavity 110, dividing the mounting cavity 110 into a first mounting chamber 111 for mounting a sewage tank 500 and a second mounting chamber 112 for mounting a clean water tank 600. A drain outlet 140 is provided on the bottom wall of either the first mounting chamber 111 or the bottom wall of the second mounting chamber 112. The bottom wall of the partition 150 is provided with an opening for connecting the first mounting chamber 111 and the second mounting chamber 112. This reduces the number of drain outlets 140, thereby reducing the number of third connecting pipes 340 and fourth connecting pipes 350, and lowering the production cost of the base station 10.

[0057] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0062] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
