[0015] In one embodiment, the cleaning device further includes a main driver that drives the main cleaning assembly, the main driver including a heat sink connected between the first water pump and the second connector; or, the heat sink connected between the second connector and the main cleaning assembly.

[0016] In one embodiment, the cleaning device further includes a third connector and a one-way air valve connected between the third connector and the water tank. The cleaning pump and the one-way air valve are respectively connected to different output positions of the third connector, and the input position of the third connector is used to connect to the water tank.

[0017] In one embodiment, the water tank has a first connecting position, a second connecting position, a third connecting position, and a fourth connecting position. The first connecting position is used to connect to a base station, the second connecting position is used to connect to the main cleaning component, the third connecting position is used to connect to the first water pump, and the fourth connecting position is used to connect to the second water pump.

Furthermore, the cleaning pump can both pump water from the base station into the water tank and pump water from the tank into the main cleaning component for cleaning, thus providing multiple functions and achieving a dual-purpose pump. This simplifies the structure of the cleaning robot. Attached Figure Description

[0034] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

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.

[0038] See Figure 1 and Figure 2An embodiment of this application provides a cleaning robot including a main unit and a cleaning device 10. The cleaning device 10 is mounted on the main unit and includes a water tank 100, a cleaning mechanism 200, a cleaning pump 300, a first water pump 410, and a second water pump 420. The cleaning mechanism 200 includes a main cleaning component 210 and a secondary cleaning component 220. The main cleaning component 210 may include a water spray bar 212 and a main mop 211, with the main mop 211 mounted on the water spray bar 212. The secondary cleaning component 220 includes a secondary mop 221, which can also be understood as an edge mop. The cleaning pump 300 is connected to the water tank 100 and is used to inject water from a base station 20 into the water tank 100. The base station 20 stores a large amount of water, and the cleaning pump 300 is used to clean the main mop 211 of the main cleaning component 210 with the water from the water tank 100. A first water pump 410 is connected between the water tank 100 and the main cleaning assembly 210. The first water pump 410 pumps water from the water tank 100 into the main mop 211 of the main cleaning assembly 210, thus wetting the main mop 211 so that it can clean the object to be cleaned. A second water pump 420 is connected between the water tank 100 and the auxiliary cleaning assembly 220. The second water pump 420 pumps water from the water tank 100 into the auxiliary mop 221 of the auxiliary cleaning assembly 220, thus wetting the auxiliary mop 211 so that it can clean the object to be cleaned.

[0039] See Figure 1 and Figure 2During operation, when the cleaning robot moves to base station 20, the cleaning pump 300 can be activated to pump water from base station 20 into water tank 100. Under the action of the cleaning pump 300, the water in water tank 100 flows into the main cleaning component 210, cleaning the main mop 211 and improving its cleanliness for reuse. Simultaneously, the second water pump 420 can be activated to pump water from water tank 100 into auxiliary cleaning component 220, cleaning the auxiliary mop 221 and improving its cleanliness for reuse. After the main mop 211 and auxiliary mop 221 are completely cleaned, ensure that the cleaning pump 300 fills water tank 100. When the cleaning robot leaves base station 20 to clean items waiting to be cleaned on the ground, the first water pump 410 can be activated to pump water from water tank 100 into the main cleaning assembly 210 to wet the main mop 211, thereby improving the cleaning effect of the main mop 211 on the items waiting to be cleaned on the ground. Simultaneously, the second water pump 420 can be activated to pump water from water tank 100 into the auxiliary cleaning assembly 220 to wet the auxiliary mop 221, thereby improving the cleaning effect of the auxiliary mop 221 on the items waiting to be cleaned on the ground. Since the water volume required for cleaning the main mop 211 is greater than the water volume required for wetting both the main mop 211 and the auxiliary mop 221, and the water volume required for cleaning the main mop 211 is also greater than the water volume required for cleaning the auxiliary mop 221, the flow rate of the cleaning pump 300 can be greater than the flow rates of the first water pump 410 and the second water pump 420.

[0040] If the cleaning pump 300 is installed on the base station 20, on the one hand, when the cleaning robot moves to the base station 20, if the cleaning pump 300 on the base station 20 malfunctions, the cleaning pump 300 will be unable to pump water from the base station 20 to clean the main mop 211 and the auxiliary mop 221, thus affecting the reliability of the cleaning robot. On the other hand, it also makes the structure of the base station 20 more complex.

[0041] See Figure 1 and Figure 2Regarding the cleaning robot in the above embodiments, since the cleaning pump 300 is integrated into the main unit of the cleaning robot, on the one hand, when the cleaning robot moves to the base station 20, the cleaning pump 300 integrated into the cleaning robot can pump water from the base station 20 into the water tank 100, thereby facilitating the cleaning of the main mop 211 and the auxiliary mop 221, thus improving the reliability of the cleaning robot. On the other hand, the cleaning pump 300 can pump water from the base station 20 into the water tank 100, and the cleaning pump 300 can also pump water from the water tank 100 into the main cleaning component 210 to clean the main mop 211. Therefore, the cleaning pump 300 has multiple functions, achieving the effect of one pump for two uses, thereby achieving the goal of reasonably simplifying the structure of the cleaning robot. Furthermore, eliminating the cleaning pump 300 from the base station 20 can also simplify the structure of the base station 20.

[0042] See Figure 1 and Figure 2 In some embodiments, the cleaning pump 300 is connected between the water tank 100 and the main cleaning assembly 210. When the cleaning robot moves to the substrate, the water tank 100 can be connected between the cleaning pump 300 and the base station 20. At this time, the cleaning pump 300 can be turned on, generating negative pressure in the water tank 100. Under the action of negative pressure, water in the base station 20 will be pumped into the water tank 100. While the water in the base station 20 flows into the water tank 100, the cleaning pump 300 can also pump water from the water tank 100 into the main cleaning assembly 210, thereby cleaning the main mop 211. Given that there is sufficient water in the water tank 100, the second water pump 420 can also pump water into the auxiliary cleaning assembly 220, thereby cleaning the auxiliary mop 221.

[0043] See Figure 1 and Figure 2 In some embodiments, the cleaning device 10 further includes a first connector 500, which can be a tee connector. The cleaning pump 300 and the first water pump 410 are respectively connected to two different input positions of the first connector 500, and the main cleaning component 210 is connected to the output position of the first connector 500. By setting the first connector 500, water from the cleaning pump 300 and the first water pump 410 is prevented from entering the main cleaning component 210 through different pipelines. This ensures that water from the cleaning pump 300 and the first water pump 410 is input to the main cleaning component 210 through the same pipeline connected to the first connector 500. This reduces the piping structure of the cleaning device 10, thereby simplifying the structure of the entire cleaning robot.

[0044] In some embodiments, the cleaning device 10 further includes a main drive 700 for driving the main mop 211 of the main cleaning assembly 210. The main drive 700 includes a heat dissipation pipe 710 through which water can pass, allowing the water in the heat dissipation pipe 710 to absorb heat from the main drive 700, thereby dissipating heat and cooling the main drive 700. See also Figure 2 For example, the heat pipe 710 can be connected between the output position of the first connector 500 and the main cleaning assembly 210. This allows water flowing from the cleaning pump 300 and the first water pump 410 into the first connector 500 to pass through the heat pipe 710 before flowing into the main cleaning assembly 210. Similarly, water flowing out of the cleaning pump 300 and the first water pump 410 can flow into the heat pipe 710 to dissipate heat from the main driver 700, thereby improving the heat dissipation effect of the main driver 700. See also... Figure 1 For example, the heat pipe 710 is connected between the first water pump 410 and the first connector 500, so that the water flowing out of the first water pump 410 will pass through the heat pipe 710 to dissipate heat from the main drive 700. In this case, it can be understood that the water flowing out of the cleaning pump 300 will not be able to pass through the heat pipe 710.

[0045] See Figure 1 and Figure 2 In some embodiments, the water tank 100 has a first communication port 110, a second communication port 120, a third communication port 130, and a fourth communication port 140. The first communication port 110 is used to connect to the base station 20, through which water in the base station 20 enters the water tank 100. The second communication port 120 is used to connect to the main cleaning assembly 210, for example, the second communication port 120 is directly connected to the cleaning pump 300, so that water in the water tank 100 flows into the main cleaning assembly 210 through the second communication port 120 and the cleaning pump 300. The third communication port 130 is used to connect to the first water pump 410, which pumps water from the water tank 100 out of the third communication port 130 to be input into the main cleaning assembly. The fourth communication port 140 is used to connect to the second water pump 420, which pumps water from the water tank 100 out of the fourth communication port 140 to be input into the auxiliary cleaning assembly. The water level at the first connecting position 110 and the second connecting position 120 is higher than the water level at the third connecting position 130 and the fourth connecting position 140. This optimizes the routing and layout of various pipelines, making the cleaning device 10 more compact in structure.

[0046] See Figure 3 and Figure 4In some embodiments, the water tank 100 is connected between the cleaning pump 300 and the main cleaning assembly 210. When the cleaning robot moves to the base station 20, the cleaning pump 300 can be connected between the water tank 100 and the base station 20. The cleaning pump 300 pumps water from the base station 20 into the water tank 100 via a clean water pump. As the cleaning pump 300 continuously pumps water into the water tank 100, a positive pressure will exist in the water tank 100. Under the action of the positive pressure, the water in the water tank 100 will flow into the main cleaning assembly 210 to clean the main mop 211. Of course, while cleaning the main mop 211, the second water pump 420 can pump water from the water tank 100 into the auxiliary cleaning assembly 220 to clean the auxiliary mop 221.

[0047] See Figure 3 and Figure 4 In some embodiments, the cleaning device 10 further includes a second connector 610 and a one-way liquid valve 620. The second connector 610 can be a three-way connector. The one-way liquid valve 620 is connected between the water tank 100 and the second connector 610. The first water pump 410 is connected between the water tank 100 and the second connector 610, and the main cleaning component 210 is connected to the second connector 610. For example, the second connector 610 and the one-way liquid valve 620 are respectively connected to different input positions of the second connector 610, and the main cleaning component 210 is connected to the output position of the second connector 610. The cleaning pump 300 is connected to the first communication position 110 of the water tank 100, so that the cleaning pump 300 inputs water from the base station 20 into the water tank 100 through the first communication position 110. The one-way liquid valve 620 is connected to the second communication position 120 of the water tank 100, so that water in the water tank 100 enters the main mop 211 through the second communication position 120 and the one-way liquid valve 620.

[0048] See Figure 3 and Figure 4 When the cleaning robot moves to the base station 20, the cleaning pump 300 pumps water from the base station 20 into the water tank 100. Under the positive pressure in the water tank 100, the water flows through the one-way valve 620 into the main mop 211, thereby cleaning the main mop 211. By setting the one-way valve 620, when the cleaning robot leaves the base station 20, the one-way valve 620 can be closed, thereby preventing water in the water tank 100 from flowing into the main cleaning assembly through the one-way valve 620, ensuring that the water in the water tank 100 flows into the main cleaning assembly through the first water pump 410.

[0049] See Figure 3 and Figure 4 In some embodiments, see Figure 4For example, the heat pipe 710 is connected between the second connector 610 and the main cleaning assembly 210. This allows water flowing from the first water pump 410 and the one-way valve 620 to the second connector 610 to pass through the heat pipe 710 before flowing into the main cleaning assembly 210. Similarly, water flowing out of the first water pump 410 and the one-way valve 620 can flow into the heat pipe 710 to dissipate heat from the main drive 700, thereby improving the heat dissipation effect of the main drive 700. See also... Figure 3 For example, the heat sink 710 is connected between the first water pump 410 and the second connector 610, so that the water flowing out of the second water pump 420 will pass through the heat sink 710 to dissipate heat from the main drive 700. In this case, it can be understood that the water flowing out of the one-way valve 620 will not be able to pass through the heat sink 710.

[0050] See Figure 3 and Figure 4 In some embodiments, the cleaning device 10 further includes a third connector 810 and a one-way valve 820. The third connector 810 can be a three-way connector, and the one-way valve 820 is connected between the third connector 810 and the water tank 100. The cleaning pump 300 and the one-way valve 820 are respectively connected to different output positions of the third connector 810, and the input position of the third connector 810 is used to connect to the water tank 100. The one-way valve 820 can also be connected to the first connection position 110 of the water tank 100, so that the external gas can enter the water tank 100 through the first connection position 110, thereby making the gas pressure in the water tank 100 equal to the external gas pressure, avoiding the formation of negative pressure in the water tank 100 during water consumption, and ensuring that the first water pump 410 and the second water pump 420 can smoothly draw water from the water tank 100. During the process of the cleaning pump 300 pumping water into the water tank 100, the water in the base station 20 cannot enter the water tank 100 through the one-way air valve 820. That is, the one-way air valve 820 only allows gas to flow and cannot allow liquid to flow.

[0051] See Figure 3 and Figure 4 In some embodiments, the cleaning device 10 further includes a wastewater container 910, a sludge pump 920, and a noise muffler 930. The wastewater container 910 is connected between the main cleaning assembly 210 and the sludge pump 920, and the noise muffler 930 is disposed on the sludge pump 920. The wastewater container 910 can contain wastewater from the main cleaning assembly, and the sludge pump 920 can discharge the wastewater buffered in the wastewater container 910. Due to the presence of the noise muffler 930, the noise generated by the sludge pump 920 during operation can be eliminated, thereby reducing noise pollution from the cleaning robot.

[0052] In some embodiments, the cleaning robot includes a main unit and a cleaning device 10, which is mounted on the main unit. The cleaning device 10 includes a water tank 100, a cleaning mechanism 200, and a third water pump. The cleaning mechanism 200 includes a main cleaning component 210, and the third water pump is connected between the water tank 100 and the main cleaning component 210. The third water pump has one or more flow patterns, allowing it to pump water from the water tank 100 into the main cleaning component 210 to clean or wet it. Alternatively, when the main unit is connected to the base station 20 via a water path, the third water pump can pump water from the base station 20 into the water tank 100 and / or the main cleaning component 210. This allows the third water pump to serve multiple purposes, simplifying the structure of the cleaning robot and the cleaning device 10.

[0053] 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. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
