[0002] With social development and technological advancements, more and more intelligent devices are being applied to people's lives. Cleaning robots, as cleaning devices that can automatically navigate and sweep and vacuum floors, effectively free users' hands compared to traditional manual cleaning, significantly reducing household chores and bringing great convenience to people's lives.

[0003] With the continuous development of cleaning robots, some cleaning robots are now equipped with independent self-service base stations. After completing a cleaning operation, the cleaning robot can automatically return to the base station to perform operations such as wastewater discharge, cleaning water replenishment, charging, and vacuuming. This automatically prepares the cleaning robot for the next cleaning session without requiring manual operation by the user, thus further improving the ease of use of cleaning robots and facilitating their further promotion.

[0004] In order to perform cleaning, wastewater recycling, and fresh water replenishment operations for cleaning robots, base stations are usually equipped with water tanks for water storage. However, during the long-term placement of the water tanks, bacteria can easily grow inside, producing an odor, which affects the user experience of the base station and poses hygiene and safety hazards.

[0018] According to another aspect of this application, a base station is provided, including the above-described filtration and sterilization device, the base station further including a water tank, the filtration and sterilization device being located inside the water tank.

[0019] In one embodiment, the main housing of the filtration and sterilization device has an installation groove at one end where the water pumping chamber is located, and the filtration and sterilization device is connected to the water tank through the installation groove.

[0032] 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.

[0033] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, 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.

[0034] Furthermore, the terms "first" and "second" are used 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 as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0038] Embodiments of the present application provide a cleaning device (not shown in the figure), including a cleaning robot and a base station configured to support the cleaning robot. The cleaning robot is used to clean the ground, and the base station is fixedly installed on the ground. After the cleaning operation of the cleaning robot is completed, the cleaning robot can enter the base station for operations such as sewage discharge, water replenishment, and charging.

[0039] Furthermore, the base station generally includes a clean water tank and a sewage tank. The clean water tank is used to clean the cleaning components of the cleaning robot and replenish water for the cleaning robot at the same time. The sewage tank is used to collect the sewage generated after the base station cleans the cleaning components. As described in the background art, during long-term placement, bacteria are likely to grow inside the clean water tank and the sewage tank. Moreover, after the sewage is collected into the sewage tank of the base station, due to the presence of a large number of bacteria in the sewage, the bacteria are likely to adhere to the sewage tank of the base station, causing secondary pollution to the sewage tank and producing a pungent smell. Therefore, users need to perform additional sterilization treatment on the clean water tank and the sewage tank, which brings inconvenience to the use of the cleaning robot.

[0040] Based on the above problems, the base station includes a sterilization and filtration device 100 (see Figure 1 ). The filtration and sterilization device 100 is disposed in the clean water tank. The filtration and sterilization device 100 is used to filter impurities in the cleaning water in the clean water tank and perform sterilization treatment on the cleaning water, so as to reduce the bacteria in the water and endow the water in the clean water tank with a sterilization function. Furthermore, the number of bacteria in the sewage collected in the sewage tank can be effectively reduced, thereby achieving comprehensive sterilization of the clean water tank of the cleaning robot, the cleaning components of the cleaning robot, the ground, and the clean water tank and sewage tank of the base station. It can be understood that in some other embodiments, the filtration and sterilization device 100 can also be disposed in the sewage tank to directly perform filtration and sterilization treatment on the sewage tank.

[0041] Please refer to Figures 1 to 4 , the filtration and sterilization device 100 includes a main housing 20, a partition member 30, a filter member 40, and a sterilization member 60.

[0042] The main housing 20 has a receiving cavity and an inlet 20b and an outlet connecting the receiving cavity to the external environment, respectively. A partition 30 is disposed within the receiving cavity, dividing it into a sterilization chamber 20a connected to the inlet 20b and a pumping chamber 20c connected to the outlet. A sterilization component 60 is located within the sterilization chamber 20a and is used to sterilize the water. A filter component 40 is disposed within the receiving cavity and is used to filter the water to block impurities. Along the length of the sterilization chamber 20a, the pumping chamber 20c is located at one end of the sterilization chamber 20a. The partition 30 has a connecting groove 30a, through which the sterilization chamber 20a and the pumping chamber 20c are interconnected.

[0043] Thus, water in the clean water tank can enter the sterilization chamber 20a through the inlet 20b. Driven by the water flow generated when the water is pumped into the pumping chamber 20c, the water passes through the connecting groove 30a of the separator 30 after being sterilized by the sterilization component 60 in the sterilization chamber 20a, and finally flows out of the pumping chamber 20c. During this process, the filter component 40 can filter the water in the filtration and sterilization device 100 to remove impurities.

[0044] The aforementioned filtration and sterilization device 100 integrates filtration and sterilization functions through the arrangement of the filter element 40 and the sterilization element 60. On the one hand, it sterilizes the cleaning water flowing out of the clean water tank, thereby effectively cleaning the cleaning components of the cleaning robot, reducing the number of bacteria in the wastewater returned to the base station's clean water tank, and effectively cleaning the ground. On the other hand, it has a high degree of integration, so it does not occupy too much space in the clean water tank. Moreover, since the pumping chamber 20c is located at one end of the length direction of the sterilization chamber 20a containing the sterilization element 60, it effectively extends the flow path of water through the sterilization chamber 20a into the pumping chamber 20c, allowing the water to fully contact the sterilization element 60 and achieving a better sterilization effect.

[0045] Please continue reading. Figures 1 to 4 The main housing 20 includes a first housing 21, a second housing 23, and a water pumping pipe 27.

[0046] The first housing 21 and the second housing 23 are fitted together to define a receiving cavity, and the partition 30 is located inside the receiving cavity and integrally formed with the first housing 21. The water suction pipe 27 is integrally formed with the second housing 23 and extends into the water suction chamber 20c through the water suction port to extract water from the water suction chamber 20c. Because the first housing 21 and the partition 30 are integrally formed, and the second housing 23 and the water suction pipe 27 are integrally formed, the overall structure and assembly process of the main housing 20 are simplified. Moreover, by opening the second housing 23, the sterilization component 130 can be easily replaced, thereby simplifying the maintenance of the filtration and sterilization device 100.

[0047] Specifically, in some embodiments, the first housing 21 is a cubic housing structure with one open end, including a bottom wall and side walls extending in the same direction from the edge of the bottom wall. Multiple water inlets 20b are provided on the side walls, and all water inlets 20b are arranged circumferentially at intervals. Each water inlet 20b is an inclined, elongated strip, thus forming a grid-like structure for preliminary filtration of impurities in the clean water tank. It is understood that the shape, number, and arrangement of the water inlets 20b can be set as needed to meet different water intake requirements.

[0048] The second housing 23 is generally flat and covers the end of the housing sidewall away from the bottom wall to form a receiving cavity. The first housing 21 and the second housing 23 can be fixed to each other by means of snap fasteners. Specifically, the housing sidewall of the first housing 21 has snap-fit ​​grooves 21a on opposite sides in the width direction, and the second housing 23 has snap fasteners 232 protruding from its two sides in the width direction, which are corresponding to the snap-fit ​​grooves. The snap fasteners 232 are detachably snapped into the snap-fit ​​grooves 21a, thereby realizing the detachable connection between the first housing 21 and the second housing 23.

[0049] It is understood that the method of fixing the first housing 21 and the second housing 23 is not limited to this. In some other embodiments, the first housing 21 and the second housing 23 may also be fixed to each other by means of interference fit, magnetic connection, pin connection, threaded connection, etc. to meet different installation requirements.

[0050] In the following embodiments, the length direction of the first housing 21 is defined as the first direction (i.e., Figure 1 In the X direction), the width direction of the first shell 21 is defined as the second direction (i.e., the X direction). Figure 1 In the Y direction), the height direction of the first shell 21 is defined as the third direction (i.e., Figure 1 The first direction, the second direction, and the third direction intersect each other. In a preferred embodiment, the first direction, the second direction, and the third direction are perpendicular to each other. In some embodiments, the bottom wall of the first housing 21 is perpendicular to the third direction, and the side walls of the housing extend from the bottom wall along the third direction. When the base station is placed on the ground, the third direction extends vertically.

[0051] like Figure 2 As shown, the cross-section of the partition 30 perpendicular to the third direction is roughly "C" shaped. One end of the partition 30 in the third direction is connected to the bottom wall of the housing, and the other end of the partition 30 extends toward the second housing 23 along the third direction. The two sides of the partition 30 in the second direction are respectively connected to one side wall of the first housing 21 in the first direction.

[0052] Thus, the two opposite sides of the separator 30 in the first direction define the sterilization chamber 20a and the water pumping chamber 20c with the side wall of the housing, respectively, and the length direction of the sterilization chamber 20a is parallel to the first direction. The end of the separator 30 facing the second housing 23 is spaced apart from the second housing 23 to form a water pumping port that communicates with the water pumping chamber 20c.

[0053] In some further embodiments, the separator 30 includes a plurality of separators, all of which are spaced apart around a third direction. Each separator extends from the bottom wall of the housing toward the second housing 23 along a third direction. A connecting groove 30a extending along a third direction is formed between every two adjacent separators 30. The sterilization chamber 20a and the water pumping chamber 20c are interconnected through these connecting grooves 30a. At the same time, the separator 30 can also serve as an isolation to prevent the sterilization component 60 in the sterilization chamber 20a from entering the water pumping chamber 20c and blocking the water pumping chamber 20c.

[0054] like Figure 2 , Figure 3 As shown in Figure 4, the water pumping pipe 27 has a hollow tubular structure. One end of the water pumping pipe 27 protrudes along the third direction on the side of the second housing 23 away from the receiving cavity to connect with the external device. The other end of the water pumping pipe 27 passes through the second housing 23 along the third direction and extends into the water pumping chamber 20c through the water pumping port.

[0055] Specifically, in some embodiments, one end face of the water pump 27 abuts against the bottom wall of the first housing 21, and at least one water inlet hole 27a is provided at the end of the water pump 27 abutting against the bottom wall of the housing. Water in the water pumping chamber 20c can enter the water pump 27 through the water inlet hole 27a, while preventing the sterilization component 60 from entering the water pump 27.

[0056] In a preferred embodiment, the end of the water inlet pipe 27 that abuts against the bottom wall of the housing has multiple water inlet holes 27a, all of which are arranged at intervals along the circumference. Therefore, water in the water inlet chamber 20c enters the water inlet pipe 27 from all sides simultaneously. It is understood that the location and number of water inlet holes 27a are not limited and can be set as needed to meet different water inlet requirements.

[0057] In some embodiments, the sterilization element 60 is formed of silver ion antibacterial material, polyferric sulfate, solid alkali aluminum, or other materials with sterilization function. In a preferred embodiment, the sterilization element 60 is a spherical structure formed of silver ion antibacterial material, and multiple sterilization elements 60 are filled in the sterilization chamber 20a to sterilize the water flowing through the sterilization chamber 20a. The water flowing through the sterilization element 60 can carry a certain number of silver ions into the pumping chamber 20c. It is understood that the material, shape, and number of the sterilization elements 60 are not limited and can be configured as needed to meet different sterilization requirements.

[0058] The filter element 40 has a mesh structure, and the porosity of the filter element 40 can be set as needed to meet different filtration requirements.

[0059] Please combine Figure 2 , Figure 5 as well as Figure 6 As shown, in some embodiments, the filter element 40 is located between the sterilization chamber 20a and the external environment and connects the sterilization chamber 20a with the external environment. Therefore, the water in the clean water tank is first filtered by the filter element 40 and then enters the sterilization chamber 20a. The water sterilized by the sterilization element 60 enters the water pumping chamber 20c through the connecting groove 30a of the separator 30 and is finally pumped out by the water pumping pipe 27.

[0060] Furthermore, in some embodiments, the filter element 40 has a cylindrical structure surrounding the sterilization chamber 20a in the circumferential direction, thereby having a large filtration area to effectively prevent clogging.

[0061] In one specific embodiment, the shape of the filter element 40 matches the shape of the side wall of the first housing 21. The filter element 40 is integrally injection molded into the side wall of the first housing 21, and the portion of the filter element 40 corresponding to the water inlet 30b is embedded in the water inlet 20b. Therefore, the water in the clean water tank is filtered by the filter element 40 as it passes through the water inlet 20b.

[0062] It is understood that the shape and fixing method of the filter element 40 located between the sterilization chamber 20a and the external environment are not limited, and can be set as needed to meet different requirements. For example, in another embodiment, the shape of the filter element 40 matches the shape of the side wall of the first housing 21, and the filter element 40 is fixed to the inner surface of the side wall of the first housing 21 by adhesive bonding and covers the water inlet 20b.

[0063] In other embodiments, the filter element 40 is disposed on the separator 30 and connected to the inlet 20b. Therefore, the water in the clean water tank first enters the sterilization chamber 20a through the inlet 20b and is sterilized by the sterilization element 60. Then, it is filtered by the filter element 40 and enters the pumping chamber 20c. Finally, it is pumped out by the pumping pipe 27.

[0064] In one specific embodiment, the shape of the filter element 40 matches the shape of the separator 30. The filter element 40 is integrally injection molded into the separator 30, and the portion of the filter element 40 corresponding to the connecting groove 30a is embedded in the connecting groove 30a. Therefore, water is filtered by the filter element 40 as it passes through the connecting groove 30a.

[0065] It is understood that the shape and fixing method of the filter element 40 located between the sterilization chamber 20a and the water pumping chamber 20c are not limited to this, and can be set as needed to meet different installation requirements. In another embodiment, the shape of the filter element 40 matches the shape of the partition 30, and the filter element 40 is connected to one side of the partition 30 by adhesive bonding and covers the connecting groove 30a.

[0066] like Figure 1 As shown, in some embodiments, the main housing 20 has a mounting groove 21b at one end where the water pumping chamber 20c is located, and the filtration and sterilization device is connected to the clean water tank through the mounting groove 21b. Specifically, in one embodiment, the mounting groove 21b is located on the first housing 21.

[0067] The aforementioned filtration and sterilization device 100 integrates the sterilization component 60 and the filter component 40, thus simultaneously performing sterilization and filtration functions. The overall structure of the filtration and sterilization device 100 is simple and reliable, and it can be easily replaced as a whole or individually with the sterilization component 60, facilitating the disassembly and maintenance of the base station and providing convenience for base station maintenance. The sterilization chamber 20a and the water pumping chamber 20c are separated by a grid-like partition 30. When water is pumped through the water pumping chamber 20c, the flow trend of the water pulls the water in the sterilization chamber 20a out, ensuring that water containing a high concentration of silver ions is extracted, maintaining the silver ion concentration in the water within the ideal range. Furthermore, since the water pumping chamber 20c is located at one end of the sterilization chamber 20a along its length, compared to the arrangement where the water pumping chamber 20c is located in the middle of the sterilization chamber 20a, the length of the sterilization chamber 20a is fully utilized, effectively extending the flow path of water in the sterilization chamber 20a. This effectively improves the sterilization effect of the filtration and sterilization device 100, thereby enhancing the cleaning effect of the cleaning robot and improving the cleanliness of the clean water tank and wastewater tank in the base station.

[0068] 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.

[0069] 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.
