[0024] The technical solution of this invention has the following advantages:

[0025] The water tank provided by this invention allows for the following process: When a user fills the clean water chamber with liquid through the inlet, as the liquid volume increases, the baffle moves towards the wastewater chamber under the influence of the liquid's potential energy, causing the clean water chamber to continuously enlarge. When this water tank is used in a cleaning robot base station, for example, when the clean water in the clean water chamber is used to clean the mop of a floor cleaning machine, the clean water in the clean water chamber is continuously consumed, while the wastewater generated during the cleaning process is continuously pumped into the wastewater chamber. The baffle gradually moves towards the clean water chamber, causing the wastewater chamber to continuously enlarge. Therefore, by incorporating a movable baffle within the tank, this water tank, compared to existing technologies, can halve the tank volume while meeting the total volume requirements for both clean and wastewater, resulting in higher space utilization and thus reducing the overall size of the cleaning robot base station.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0046] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] Example 1

[0048] Currently, cleaning robots mainly fall into three categories: first, robot vacuums that combine sweeping and mopping; second, robot vacuums that only vacuum and sweep; and third, robot mops that only mop. The mopping robot requires a base station capable of cleaning its cleaning components. This base station has a wastewater tank and a clean water tank. To address the issue of frequent water refills and emptying, both tanks are relatively large, preventing the base station from being miniaturized, resulting in a bulky and space-consuming system with high costs.

[0049] Therefore, this embodiment provides a water tank that, when applied to a cleaning robot base station, can reduce its volume compared to existing technologies, thereby reducing the overall size of the cleaning robot base station.

[0050] In one implementation, such as Figures 1 to 10As shown, the water tank includes a tank body 1 and a baffle 2 movably disposed inside the tank body 1. The tank body 1 has a water inlet 101. The baffle 2 divides the tank body 1 into a clean water chamber 3 and a wastewater chamber 4. The clean water chamber 3 has a water outlet, and the wastewater chamber 4 has a water return outlet.

[0051] In this embodiment, when the user fills the clean water chamber 3 with liquid through the water inlet 101, as the liquid in the clean water chamber 3 increases, the baffle 2 moves towards the wastewater chamber 4 under the influence of the liquid's potential energy, and the clean water chamber 3 continuously enlarges. When this water tank is used in a cleaning robot base station, for example, when the clean water in the clean water chamber 3 is used to clean the mop of a floor cleaning machine, the clean water in the clean water chamber 3 is continuously consumed, while the wastewater generated during the cleaning process is continuously pumped into the wastewater chamber 4, causing the baffle 2 to gradually move towards the clean water chamber 3, and the wastewater chamber 4 to continuously enlarge. Therefore, by setting a baffle 2 inside the tank body 1 and making the baffle 2 movable, compared with the prior art, this water tank can reduce the volume of the tank body 1 by half while meeting the total amount requirements of clean water and wastewater, resulting in high space utilization and thus reducing the volume of the cleaning robot base station.

[0052] like Figure 1 As shown, the top of the tank 1 has a water inlet 101, through which water can be injected into the tank 1 or water can be extracted from the tank 1.

[0053] Based on the above embodiments, in a preferred embodiment, such as Figure 4 As shown, the baffle 2 includes a main body 201, first fixed ends 202 located on both sides of the main body 201, and a second fixed end 203 located at the bottom of the main body 201. The two first fixed ends 202 are respectively fixedly connected to the side walls of the housing 1, and the second fixed end 203 is fixedly connected to the bottom wall of the housing 1. The main body 201 is made of elastic material. In this embodiment, since the sides and bottom of the main body 201 are fixed, and the main body 201 is made of elastic material, when the user fills the clean water chamber 3 with liquid through the water inlet 101, as the liquid in the clean water chamber 3 increases, the main body 201 deforms and moves towards the wastewater chamber 4 under the action of liquid potential energy, and the clean water chamber 3 continuously increases in size. When this water tank is used in a cleaning robot base station, for example, when the clean water in the clean water chamber 3 is used to clean the mop of the floor cleaning machine, the clean water in the clean water chamber 3 is continuously consumed, and the wastewater generated during the cleaning process is continuously drawn into the wastewater chamber 4. Under the action of liquid potential energy, the main body 201 gradually deforms and moves towards the clean water chamber 3, and the wastewater chamber 4 continuously increases in size. In this embodiment, no additional drive mechanism is required; the main body 201 automatically deforms and moves using the potential energy of water, resulting in a simple structure. In an alternative embodiment, a drive mechanism can be provided, which is connected to the baffle 2 and can drive the baffle 2 to move toward the clean water chamber 3 or the wastewater chamber 4.

[0054] The main body 201 is made of a ductile material, such as rubber or silicone.

[0055] Based on the above embodiments, in a preferred embodiment, a first fixing plate 5 is fixedly connected to two opposite side walls of the housing 1, and a plurality of first grooves 501 are spaced apart on the surface of the first fixing plate 5 and the side wall connected thereto. Figure 5 As shown, the first fixed end 202 includes a plurality of first protrusions 2021 adapted to the first groove 501. In this embodiment, the first fixed plate 5 is fixedly connected to the two opposite side walls of the housing 1 respectively, and the first fixed end 202 and the first fixed plate 5 are fixedly connected by the first protrusions 2021 and the second groove. The fixing method of the baffle 2 is simple and convenient, and the assembly process is easy to operate. In other alternative embodiments, the first fixed end 202 can be directly fixedly connected to the side wall of the housing 1.

[0056] In a preferred embodiment, such as Figure 8 As shown, two symmetrically arranged first fixing plates 5 can be connected to each side wall, forming a gap between the two first fixing plates 5 suitable for the main body 201 to pass through, and the two first fixing plates 5 clamp the main body 201 therein. In this embodiment, the two sides of the baffle 2 can be stably fixed to the side wall of the box 1.

[0057] The first fixing plate 5 can be connected to the side wall of the box 1 by screws or clips.

[0058] Based on the above embodiments, in a preferred embodiment, the cross-section of the first groove 501 is a dovetail groove, and correspondingly, the first protrusion 2021 is a dovetail tooth. In this embodiment, it can be ensured that the first protrusion 2021 will not come out of the first groove 501, thereby ensuring that the two sides of the baffle 2 are stably fixed to the side wall of the housing 1.

[0059] Based on the above embodiments, in a preferred embodiment, such as Figure 10 As shown, the first fixing plate 5 includes a first flat surface 502 adapted to abut against the side wall. The first fixing plate 5 has a first mounting groove, and a first recess 501 is disposed in the first mounting groove. The first fixing end 202 includes a first plate-like member 2022. The side of the first plate-like member 2022 away from the main body 201 is a second flat surface 20221. A first protrusion 2021 is disposed on the first plate-like member 2022. After the first protrusion 2021 is embedded in the first recess 501, the second flat surface 20221 is flush with the first flat surface 502. In this embodiment, after assembly, the first fixing end 202 is in contact with the side wall of the housing 1, thereby ensuring that water will not enter between them, achieving a sealed connection, and preventing the mixing of clean water and sewage.

[0060] Based on the above embodiments, in a preferred embodiment, a second fixing plate 6 is fixedly connected to the bottom wall of the housing 1, two first fixing plates 5 are respectively pressed against the two ends of the second fixing plate 6, and a plurality of second grooves are spaced apart on the surface of the second fixing plate 6 facing the bottom wall, such as... Figure 3 and Figure 6 As shown, the second fixing end 203 includes a plurality of second protrusions 2031 adapted to the second groove. In this embodiment, the first fixing plate 5 can press the second fixing plate 6 onto the bottom wall of the housing 1, thereby fixing the second fixing plate 6 to the bottom wall of the housing 1. The second fixing plate 6 and the second fixing end 203 are fixedly connected by the second groove and the second protrusions 2031 engaging. The fixing method of the baffle 2 is simple and convenient, and the assembly process is easy to operate. In other alternative embodiments, the second fixing end 203 can be directly fixedly connected to the bottom wall of the housing 1.

[0061] Based on the above embodiments, in a preferred embodiment, the second groove is a dovetail groove, and correspondingly, the second protrusion 2031 is a dovetail tooth. In this embodiment, it can be ensured that the second protrusion 2031 will not come out of the second groove, thereby ensuring that the bottom of the baffle 2 is stably fixed to the bottom wall of the housing 1.

[0062] Based on the above embodiments, in a preferred embodiment, the second fixing plate 6 includes a third plane adapted to abut against the bottom wall. The second fixing plate 6 has a second mounting groove, and a second recess is disposed within the second mounting groove. The second fixing end 203 includes a second plate-like member 2032. The side of the second plate-like member 2032 away from the main body 201 is a fourth plane 20321. A second protrusion 2031 is disposed on the second plate-like member 2032. After the second protrusion 2031 is embedded in the second recess, the fourth plane 20321 is flush with the third plane. In this embodiment, after assembly, the second fixing end 203 is in contact with the bottom wall of the housing 1, thereby ensuring that water will not enter between them, achieving a sealed connection, and preventing the mixing of clean water and sewage.

[0063] Example 2

[0064] This embodiment provides a cleaning robot base station, such as Figures 11 to 14As shown, the system includes a housing 7, a cleaning mechanism 23 housed within the housing 7, and a water tank as described in the above embodiment. The cleaning mechanism 23 has a water inlet and a water outlet. The water inlet is connected to the clean water chamber 3 via a water inlet pipe, and the water outlet is connected to the wastewater chamber 4 via a drain pipe. In this embodiment, the user fills the clean water chamber 3 with liquid through the water inlet 101. As the liquid in the clean water chamber 3 increases, the baffle 2 moves towards the wastewater chamber 4 under the influence of the liquid's potential energy, causing the clean water chamber 3 to continuously increase in size. When the clean water in the clean water chamber 3 is used to clean the mop of the floor cleaning robot, the clean water in the clean water chamber 3 is continuously transported to the cleaning mechanism 23 through the water inlet pipe and consumed. Meanwhile, the wastewater generated during the cleaning process is continuously drawn into the wastewater chamber 4 by the drain pipe, causing the baffle 2 to gradually move towards the clean water chamber 3, and the wastewater chamber 4 to continuously increase in size. Therefore, compared with the prior art, the volume of the water tank 1 can be halved while meeting the total requirements for clean water and wastewater, resulting in high space utilization and thus reducing the volume of the cleaning robot base station.

[0065] like Figure 11 As shown, the housing 7 includes a main body 701 and a cover 702 provided at the top of the main body 701. The cover 702 is provided on the main body 701 in an openable and closable manner. When the cover 702 is opened, the dust collection structure 18 can be cleaned and the water tank can be filled or the water in the water tank can be extracted.

[0066] Based on the above embodiments, in a preferred embodiment, such as Figure 12 As shown, the housing 7 is provided with a first partition 8, which divides the housing 7 into an upper space and a lower space. The water tank is located in the upper space, and the cleaning mechanism 23 is located in the lower space. In this embodiment, the space in the vertical direction can be fully utilized, thereby reducing the space occupied by the cleaning robot base station in the horizontal direction.

[0067] like Figure 12 As shown, charging terminals 22 are provided on the bottom and side walls of the lower space to facilitate charging of the cleaning robot.

[0068] Based on the above embodiments, in a preferred embodiment, a first interlayer space is formed between the box body 1 and the rear side wall of the shell 7. The water inlet pipe includes a first water pump 9, a water suction pipe 10, and a water outlet pipe 11. The first water pump 9 is mounted on the first partition 8 and located in the first interlayer space. One end of the water suction pipe 10 is connected to the clean water chamber 3, and the other end is connected to the water inlet of the first water pump 9. The water outlet pipe 11 is disposed through the first partition 8. One end of the water outlet pipe 11 is connected to the water outlet of the first water pump 9, and the other end is connected to the water inlet. And / or, the drainage pipe includes a second water pump 12, a recovery pipe 13, and a drain pipe 14. The second water pump 12 is mounted on the first partition 8 and located in the first interlayer space. One end of the recovery pipe 13 is connected to the drain outlet, and the other end is connected to the water inlet of the second water pump 12. The recovery pipe 13 is disposed through the first partition 8. One end of the drain pipe 14 is connected to the water outlet of the second water pump 12, and the other end is connected to the sewage chamber 4. In this embodiment, when the cleaning module of the cleaning robot, such as the mop, needs to be cleaned, the first water pump 9 operates, and the clean water in the clean water chamber 3 is transported to the cleaning mechanism 23 through the water suction pipe 10 and the water outlet pipe 11, so as to provide clean water for the cleaning mechanism 23. When the second water pump 12 operates, the wastewater generated during the cleaning process can be discharged into the wastewater chamber 4 through the recycling pipe 13 and the drain pipe 14.

[0069] Based on the above embodiments, in a preferred embodiment, a first support plate 15 is vertically movably provided in the lower space, and a cleaning mechanism 23 is disposed on the first support plate 15. In this embodiment, by vertically movably providing the first support plate 15, the space in the vertical direction can be fully utilized. When the first support plate 15 is raised, the space below the first support plate 15 can be used for charging or dust collection of other cleaning robots.

[0070] Based on the above embodiments, in a preferred embodiment, a second support plate 16 is further provided in the lower space, located below the first support plate 15. The second support plate 16 has a dust suction port 17. The upper space also includes a dust collection structure 18 and a fan 19. The dust collection structure 18 has a dust collection chamber, which is connected to the dust suction port 17 via an air duct structure 20. The air inlet of the fan 19 is connected to the dust collection chamber. In this embodiment, when it is necessary to suck up the debris from the cleaning robot's dust box, the cleaning robot is placed on the first support plate 15, and its exhaust port is aligned with the dust suction port 17 on the first support plate 15. The fan 19 operates, sucking the debris from the cleaning robot's dust box into the dust collection structure 18 through the air duct structure 20. Therefore, this cleaning robot base station can meet the user's simultaneous need for dust collection and water washing functions, and can accommodate at least two cleaning robots simultaneously, requiring only one base station to serve multiple cleaning robots.

[0071] like Figure 12 As shown, the first support plate 15 is inclined, and its bottom surface forms a second interlayer space with the shell 7. A second partition 21 is provided inside the shell 7, and a third interlayer space is formed between the second partition 21 and the side wall of the shell 7. Both the first support plate 15 and the second support plate 16 are connected to the second partition 21. The air duct structure 20 includes a first air duct 2001 located in the second interlayer space and a second air duct 2002 located in the third interlayer space. In this embodiment, by tilting the first support plate 15 and forming a second interlayer space between its bottom surface and the shell 7, it is convenient for the cleaning robot to mount onto the first support plate 15. The second partition 21, which forms a second interlayer space with the side wall of the shell 7, conceals the first air duct 2001 and the second air duct 2002 in the second and third interlayer spaces, respectively. This cleaning robot base station has a reasonable layout, an aesthetically pleasing appearance, and makes full use of the space in the vertical direction.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
