[0002] With the development of modern society, in order to save time and maintain household hygiene, more and more people are buying cleaning equipment to clean their homes promptly and conveniently. Cleaning equipment can automatically clean floors throughout the room.

[0003] The cleaning equipment in related technologies are mostly robotic vacuum cleaners and mops. After performing cleaning tasks, these robots usually need to return to the cleaning base station to recharge.

Therefore, it is necessary to ensure that the cleaning equipment can stably connect with the charging module of the cleaning base station while it is charging.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this disclosure is to provide a cleaning base station, cleaning equipment, and cleaning system that improves the reliability of the connection between the cleaning equipment and the charging components on the cleaning base station.

[0006] According to one aspect of this disclosure, a clean base station is provided, the clean base station comprising: Base station body; A first positioning component is disposed on the base station body, and the first positioning component includes a positioning protrusion. A first charging component, comprising a base station electrode disposed on the positioning protrusion, wherein the base station electrode is used to achieve electrical connection with the cleaning equipment.

[0007] In one exemplary embodiment of this disclosure, the dimensions of the positioning protrusion decrease in the width and / or height direction of the base station body along the direction from the bottom to the top.

[0011] In one exemplary embodiment of this disclosure, the clean base station further includes: A water supply nozzle is located on the positioning protrusion and is used to connect with the water inlet of the cleaning equipment.

[0012] In an exemplary embodiment of this disclosure, the positioning protrusion has base station electrodes on both sides of the base station body in the width direction, and the water supply nozzle is located between the base station electrodes on both sides of the positioning protrusion.

[0013] According to another aspect of this disclosure, a cleaning apparatus is provided, the cleaning apparatus comprising: Equipment body; A second positioning component is disposed on the device body, and the second positioning component includes a positioning groove; The second charging component includes a device electrode disposed in the positioning groove, and the device electrode is used to achieve electrical connection with the clean base station.

[0014] In one exemplary embodiment of this disclosure, the positioning groove gradually expands toward the opening side.

[0015] In one exemplary embodiment of this disclosure, the second charging component includes a first device electrode and a second device electrode, which are located on two opposing groove walls in the positioning groove.

[0016] In one exemplary embodiment of this disclosure, the cleaning device further includes: The water inlet is located in the positioning groove, and the first device electrode and the second device electrode are located on both sides of the water inlet.

[0017] In one exemplary embodiment of this disclosure, the cleaning device includes a top cover, a bottom shell, and a side surface located between the top cover and the bottom shell, with the positioning groove located on the side surface.

[0018] In one exemplary embodiment of this disclosure, the cleaning device is a self-propelled cleaning device.

[0019] According to another aspect of this disclosure, a cleaning system is provided, the cleaning system comprising: The aforementioned clean base stations; The cleaning equipment described above is capable of positioning and docking with the cleaning base station through the positioning protrusion and the positioning groove, so that the equipment electrode and the base station electrode are positioned, docked, and connected.

[0020] In one exemplary embodiment of this disclosure, the positioning groove gradually expands toward the opening side.

[0021] In one exemplary embodiment of this disclosure, the first positioning component includes a first base station electrode and a second base station electrode, and the second charging component includes a first device electrode and a second device electrode; the first base station electrode is used to connect and conduct with the first device electrode, and the second base station electrode is used to connect and conduct with the second device electrode.

[0022] The cleaning base station disclosed herein integrates base station electrodes with positioning protrusions, achieving unified positioning and charging functions. While ensuring precise docking between the cleaning equipment and the cleaning base station, the positioning structure, with the base station electrodes located on the positioning structure, allows for better maintenance of relative position accuracy during docking, reducing the impact of equipment vibration or offset. Compared to existing technologies where the charging pad and positioning structure are separate, leading to increased cumulative vibration and offset at the charging contact point, this significantly improves the stability of the electrical connection between the base station electrodes and the cleaning equipment during charging. For example, during dust collection and / or mop cleaning on the cleaning base station, even if the cleaning equipment vibrates to some extent, the effective constraint of the positioning structure on the base station electrode position ensures that the second charging component and the first charging component maintain a stable docking and conductive state, thereby ensuring smooth charging and improving the user experience.

[0041] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0042] Embodiments of this disclosure provide a cleaning system, such as Figure 1 As shown, the cleaning system includes a cleaning device 10 and a cleaning base station 20. The cleaning device 10 can be, for example, a mopping robot, a sweeping robot, or a combined sweeping and mopping robot; the cleaning device 10 may include a device body, a drive module, a sensing module, a control module, a cleaning module, an energy module, and a human-machine interaction module. The cleaning base station 20 is used to dock with the cleaning device 10, allowing the cleaning device 10 to be parked. The cleaning device 10 can perform functions such as charging, self-cleaning, docking, sewage discharge, water replenishment, and dust collection on the cleaning base station 20.

[0043] In some embodiments, the device body is configured to automatically move along a target direction on a travel surface, which can be the surface to be cleaned by the cleaning device 10. If the cleaning device 10 is a sweeping and mopping robot, then the cleaning device 10 operates on the ground.

[0044] In some embodiments, the drive module may include a drive wheel assembly. The drive module can simultaneously control the left and right wheels. For more precise control of the machine's movement, the drive module preferably includes a left drive wheel assembly and a right drive wheel assembly. The left and right drive wheel assemblies are symmetrically arranged along a transverse axis defined by the device body. In some embodiments, to enable the automatic cleaning device 10 to move more stably or with greater mobility on the ground, the automatic cleaning device 10 may include one or more steering wheels. These steering wheels may be driven wheels or drive wheels, and their structural forms include, but are not limited to, casters. The steering wheels may be located in front of the drive wheel assembly. A drive motor provides power to the drive wheel assembly and / or the steering wheels.

[0045] In some embodiments, the cleaning device 10 may be a self-propelled cleaning device. The sensing module may include a position determination device located above the device body, a buffer located on the forward portion of the device body, and a cliff sensor and ultrasonic sensor, infrared sensor, magnetometer, accelerometer, gyroscope, odometer, and other sensing devices located at the bottom of the device body, providing the control module with various position and motion state information of the device body. For example, the forward portion of the device body is provided with a buffer. During the cleaning process, when the drive wheel assembly propels the cleaning device 10 to walk on the ground, the buffer detects one or more objects in the travel path of the cleaning device 10 via a sensor module, such as a collision sensor. The cleaning device 10 can pass through the objects detected by the collision sensor, such as steps, obstacles, or walls, and the control drive structure makes the cleaning device 10 respond to the objects, such as stepping over steps.

[0046] In some embodiments, the control module can combine distance and speed information fed back from sensors such as buffers, cliff sensors, ultrasonic sensors, infrared sensors, magnetometers, accelerometers, gyroscopes, and odometers to comprehensively determine the current working state of the robot vacuum cleaner, such as climbing stairs, crossing thresholds, walking on carpets, being on a cliff, stuck above or below, having a full dustbin, or being picked up. It will also provide specific next action strategies for different situations, making the cleaning device 10 work more in line with the user's requirements and providing a better user experience. Furthermore, the control module can plan the most efficient and reasonable cleaning path and cleaning method based on real-time map information drawn using SLAM (Simultaneous Localization and Mapping), which can improve the cleaning efficiency of the cleaning device 10.

[0047] In some embodiments, the energy module may include a rechargeable battery, such as a nickel-metal hydride battery or a lithium battery. The rechargeable battery may be connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit. These circuits are then connected to a microcontroller control circuit. The main unit is charged by connecting to a charging station via charging electrodes located on the side or bottom of the device.

[0048] In some embodiments, the human-machine interface module may include buttons on the main control panel for users to select functions; it may also include a display screen and / or indicator lights and / or a speaker, which display the current status of the machine or the available function options to the user; and it may also include a mobile client application. For path navigation cleaning equipment, the mobile client can display a map of the environment where the equipment is located, as well as the machine's position, and can provide users with richer and more user-friendly functions.

[0049] In some embodiments, the cleaning module may include a dry cleaning module, or a dry and wet cleaning module. The dry cleaning module may include a roller brush assembly, side brushes, etc., while the wet cleaning module may include cleaning components, a water tank, etc. The cleaning components in the wet cleaning module may be mopping components, such as roller mops or belt mops, for mopping and washing the surface to be cleaned.

[0050] Currently, self-propelled cleaning devices can autonomously clean indoor floors. When charging is required, the device automatically locates a cleaning base station. After docking, the second charging component on the self-propelled cleaning device contacts the first charging component on the cleaning base station, enabling the cleaning base station to charge the self-propelled cleaning device. However, because the mounting accuracy and posture of the self-propelled cleaning device are dynamic and vary considerably, and because the device vibrates relative to the cleaning base station during dust collection and mop washing, the contact between the second and first charging components becomes unstable, leading to charging failures. This affects the next use of the cleaning device and consequently impacts the user experience.

[0051] In related technologies, a positioning structure is provided between the cleaning device 10 and the cleaning base station 20 to maintain the stability of their positions. However, due to the certain distance between the charging terminal and the positioning structure, the jitter and offset of the contact position of the charging terminal on the cleaning device 10 and the cleaning base station 20 will accumulate and increase, resulting in unstable contact of the charging terminal.

[0052] To address the aforementioned technical problems, embodiments of this disclosure provide a clean base station 20, such as... Figure 2 and Figure 8As shown, the cleaning base station 20 includes a base station body 21, a first positioning component, and a first charging component 22. The first positioning component is disposed on the base station body 21 and includes a positioning protrusion 23. The first charging component 22 includes a base station electrode, which is disposed on the positioning protrusion 23. The base station electrode is used to achieve electrical connection with the cleaning device 10.

[0053] The cleaning base station 20 provided in this disclosure integrates the base station electrodes with the positioning protrusion 23, achieving a unified positioning and charging function. While ensuring precise docking between the cleaning device 10 and the cleaning base station 20, the positioning structure, with the base station electrodes located on it, allows for better maintenance of relative position accuracy during docking, reducing the impact of device vibration or offset. Compared to the prior art where the charging pad and positioning structure are separated, leading to a cumulative increase in vibration and offset at the charging contact point, this disclosure significantly improves the stability of the electrical connection between the base station electrodes and the cleaning device 10 during charging. For example, during dust collection and / or mop cleaning on the cleaning base station 20, even if the cleaning device 10 vibrates to some extent, the effective constraint of the positioning structure on the position of the base station electrodes ensures that the second charging component 12 and the first charging component 22 maintain a stable docking and conduction state, thereby ensuring smooth charging and improving the user experience.

[0054] Embodiments of this disclosure also provide a cleaning device 10, such as... Figures 2-13 As shown, the cleaning device 10 has a second charging component 12 and a positioning groove 13 on its main body 11. The second charging component 12 includes device electrodes, which are located in the positioning groove 13. The cleaning device 10 and the cleaning base station 20 can be positioned and docked with each other through the positioning protrusion 23 and the positioning groove 13, so that the device electrodes and the base station electrodes are positioned, docked, and connected.

[0055] The cleaning device 10 disclosed herein integrates a second charging component 12 on the device body 11 with a positioning groove 13, and a first charging component 22 with a positioning protrusion 23, achieving integrated positioning and charging functions. The positioning structure formed by the positioning groove 13 and the positioning protrusion 23 ensures precise docking between the cleaning device 10 and the cleaning base station 20. Because the first positioning component and the second charging component 12 are located on the positioning structure, they maintain accurate relative positions during docking, reducing the impact of device vibration or offset and improving the stability of charging terminal contact during charging. When the cleaning device 10 approaches the cleaning base station 20, the positioning protrusion 23 accurately inserts into the positioning groove 13. This tight fit restricts the displacement and shaking of the cleaning device 10 in all directions, thereby improving the positioning accuracy between the cleaning device 10 and the cleaning base station 20. The positioning structure of the positioning protrusion 23 and the positioning groove 13 has low processing difficulty, does not require complex manufacturing processes or high-precision processing equipment, and can reduce production costs and improve production efficiency. Furthermore, the device electrodes are located in the positioning groove 13, which enables the hidden assembly of the device electrodes on the cleaning device 10. During the autonomous movement of the cleaning device 10, the direct contact between the charging components and the external environment is reduced, thus lowering the risk of the electrodes being contaminated by dust and dirt. It also avoids the need to set protruding positioning protrusions 23 on the cleaning device 10, thereby preventing interference between the positioning protrusions 23 and other objects in the cleaning environment during the autonomous movement of the cleaning device 10, and improving the passability of the cleaning device 10.

[0056] The positioning groove 13 is disposed on the device body 11 of the cleaning device 10. The device body 11 includes, for example, a first mounting housing. The positioning groove 13 can be formed on the first mounting housing and can be an integrally molded structure formed on the first mounting housing. The positioning protrusion 23 can be disposed on the base station body 21 of the cleaning base station 20. The base station body 21 includes, for example, a second mounting housing. The positioning protrusion 23 can be formed on the second mounting housing and can be an integrally molded structure formed on the second mounting housing.

[0057] In some embodiments, the cleaning device 10 includes a top cover 111, a bottom shell, and a side surface 112 located between the top cover 111 and the bottom shell, with a positioning groove on the side surface 112. When the cleaning device 10 docks with the cleaning base station 20, the side surface 112 is more easily aligned with the corresponding structure of the cleaning base station 20, facilitating docking operations and positioning. When the cleaning device 10 approaches the cleaning base station 20, the positioning groove on the side surface 112 can more easily align with the positioning protrusion on the cleaning base station 20, meaning the moving direction of the cleaning device 10 can be parallel to the heating docking direction of the positioning groove and the positioning protrusion, improving docking convenience and increasing the success rate and efficiency of docking. Furthermore, the side surface 112 has ample space available for installing the positioning groove, the second charging component 12, the water inlet 14, and other components. Simultaneously, it does not occupy space on the top cover 111 and the bottom shell, allowing the top cover 111 to be used for installing the operation panel, sensors, and other components, and the bottom shell to be used for installing the cleaning mechanism, drive wheels, etc., improving the utilization rate of the internal space of the device.

[0058] In some embodiments, such as Figure 5 As shown, the positioning groove 13 gradually expands towards the opening, and the positioning protrusion 23 matches the shape of the positioning groove 13. During the process of the cleaning device 10 approaching the cleaning base station 20, the gradually expanding positioning groove 13 provides a larger entrance for the positioning protrusion 23, making it easier for the protrusion 23 to find the entrance of the positioning groove 13. Even if the cleaning device 10 has a certain angular deviation or positional error during movement, the gradually expanding positioning groove 13 can effectively guide the positioning protrusion 23 into the groove for docking, significantly improving the success rate of docking between the cleaning device 10 and the cleaning base station 20, reducing waiting time, and improving the working efficiency of the equipment. Simultaneously, after the positioning protrusion 23 enters the positioning groove 13, as the fit between the two gradually tightens, the gradually expanding positioning groove 13 can better adapt to the slight displacement and adjustment of the positioning protrusion 23 during the docking process, further improving the accuracy and stability of the positioning. Furthermore, after the cleaning device 10 is connected to the cleaning base station 20, even if it is affected by factors such as the vibration of the device itself, the tight and stable cooperation between the positioning protrusion 23 and the positioning groove 13 can ensure that the relative position of the cleaning device 10 and the cleaning base station 20 remains stable, thereby ensuring that the connection between the second charging component 12 and the first charging component 22 is not affected, and improving the stability and reliability of charging.

[0059] The positioning groove 13 extends in the direction (first direction X) where the positioning protrusion 23 mates with the positioning groove 13. The positioning groove 13 gradually increases in size along the first direction X towards the opening side in the second direction Y and / or the third direction Z. That is, the positioning groove 13 has a larger size at the opening and a smaller size at the bottom. The change in size from the opening to the bottom can be continuous or gradual, meaning there is a portion of constant size between two adjacent changing parts. The positioning groove 13 can be conical, frustum-shaped, pyramidal, truncated pyramid, or irregular in shape, as long as the size of the positioning groove 13 gradually decreases in the direction towards the bottom.

[0060] In this design, the bottom of the positioning protrusion 23 points towards the top (first direction X). The dimensions of the positioning protrusion 23 decrease in the width direction (second direction Y) and / or height direction (third direction Z) of the base station body. This means the shape of the positioning protrusion 23 matches that of the positioning groove 13, and the outer contour of the positioning protrusion 23 is consistent with or substantially consistent with the shape of the positioning groove 13. This ensures that the distance between the relative positions of the outer surface of the positioning protrusion 23 and the groove wall 131 of the positioning groove 13 remains essentially consistent, reducing the gap after the positioning protrusion 23 and the positioning groove 13 are joined, thereby improving the stability after their joining. For example, if the positioning groove 13 is frustum-shaped, the positioning protrusion 23 can also be frustum-shaped, allowing the positioning protrusion 23 and the positioning groove 13 to be highly integrated and joined together.

[0061] In some embodiments, such as Figures 4-7 As shown, the second charging component 12 includes a first device electrode 121 and a second device electrode 122; as Figures 8-11 As shown, the first charging component 22 includes a first base station electrode 221 and a second base station electrode 222; as Figure 12 and Figure 13 As shown, the first device electrode 121 is used to dock with the first base station electrode 221, and the second device electrode 122 is used to dock with the second base station electrode 222.

[0062] In this configuration, the first device electrode 121 and the second device electrode 122 have opposite polarities, and the first base station electrode 221 and the second base station electrode 222 have opposite polarities. For example, both the first device electrode 121 and the first base station electrode 221 are positive electrodes, and both the second device electrode 122 and the second base station electrode 222 are negative electrodes. In some embodiments, the second charging component 12 and the first charging component 22 may further include more electrode terminals, which, after docking, can serve as a communication channel between the cleaning device 10 and the cleaning base station 20, for example.

[0063] In some embodiments, the first device electrode 121 and the second device electrode 122 are spaced apart in the positioning groove 13, and the first base station electrode 221 and the second base station electrode 222 are spaced apart on the positioning protrusion 23. This spaced-apart arrangement of the first device electrode 121 and the second device electrode 122 in the positioning groove 13, and the first base station electrode 221 and the second base station electrode 222 on the positioning protrusion 23, effectively avoids the risk of short circuits between the electrodes. During the docking process between the cleaning device 10 and the cleaning base station 20, if the electrode terminals are too close, the presence of impurities such as dust and water droplets may cause a short circuit, affecting the charging effect or even damaging the device. By reasonably spacing the electrodes, the distance between the electrode terminals is increased, reducing the possibility of short circuits caused by impurities.

[0064] Among them, such as Figure 5 As shown, the first device electrode 121 and the second device electrode 122 are respectively located on two opposite groove walls 131 in the positioning groove 13 along the first direction X; Figure 9 As shown, the first base station electrode 221 and the second base station electrode 222 are respectively located on two opposite sidewalls 231 of the positioning protrusion 23 along the first direction X. During the docking process between the cleaning device 10 and the cleaning base station 20, when the positioning protrusion 23 is inserted into the positioning groove 13, the corresponding electrode terminals can gradually come into contact with each other as the positioning protrusion 23 is inserted. Since the positioning groove 13 is gradually expanding and the shape of the positioning protrusion 23 matches that of the positioning groove 13, the corresponding electrode terminals are parallel to each other and intersect in the opposite direction to the docking of the positioning protrusion 23 and the positioning groove 13, which can improve the reliability of the docking of the corresponding electrode terminals. Even when the attitude of the cleaning device 10 relative to the cleaning base station 20 changes or there is a positioning error, the corresponding electrode terminals can still reliably dock together. In other embodiments, the first device electrode 121 and the second device electrode 122 may also be located on the top and bottom groove walls of the positioning groove 13 opposite each other in the third direction Z, and the first base station electrode 221 and the second base station electrode 222 may also be located on the top and bottom side walls of the positioning protrusion 23 opposite each other in the third direction Z. When the positioning protrusion 23 is inserted into the positioning groove 13, the first device electrode 121 and the second device electrode 122 abut against each other, and the first base station electrode 221 and the second base station electrode 222 abut against each other.

[0065] In some embodiments, at least one of the second charging component 12 and the first charging component 22 is an elastic charging component. After the cleaning device 10 and the cleaning base station 20 are positioned and docked, the first charging component 22 and the second charging component 12 are elastically docked. During the docking process between the second charging component 12 and the first charging component 22, due to factors such as manufacturing process and installation accuracy, there may be a certain slight deviation between the cleaning device 10 and the cleaning base station 20. The elastic charging component can adapt to these deviations through its own elastic deformation, ensuring that the second charging component 12 and the first charging component 22 can be tightly docked and connected. At the same time, after the cleaning device 10 and the cleaning base station 20 are docked, the elastic force of the elastic charging component can maintain a continuous and stable contact pressure between the second charging component 12 and the first charging component 22. Even if slight vibration or displacement occurs during the operation of the cleaning device 10, the elastic effect of the elastic charging component can maintain the stability of the contact pressure, avoiding current fluctuations or contact interruptions caused by changes in contact pressure. Furthermore, during the multiple docking processes between the cleaning device 10 and the cleaning base station 20, the hard contact between traditional rigid charging components can easily lead to wear on the electrode terminal surface, affecting the conductivity of the electrodes; while the elastic charging component can buffer the contact impact force through elastic deformation during docking, reducing friction and compression between the electrode terminals and reducing wear.

[0066] The first charging component 22 mounted on the positioning protrusion 23 of the cleaning base station 20 can be a flexible charging component. When the cleaning device 10 docks with the cleaning base station 20, the positioning protrusion 23 inserts into the positioning groove 13. At this time, the flexible charging component on the positioning protrusion 23 faces the second charging component 12 in the positioning groove 13. When the positioning protrusion 23 is inserted into the positioning groove 13, the flexible charging component can gradually undergo elastic deformation as it is inserted, ensuring close contact with the second charging component 12 and improving the reliability of electrode docking. At the same time, since the flexible charging component requires a large assembly space and the installation space on the cleaning device 10 is limited, setting the flexible charging component on the cleaning base station 20 can make full use of the installation space on the cleaning base station 20 and avoid occupying the installation space of the cleaning device 10. In addition, the flexible charging component on the cleaning base station 20 is in a non-docked state. During the autonomous cleaning process, the cleaning device 10 can avoid damage and contamination of the flexible charging component by the external environment, keeping the flexible charging component clean and in good condition.

[0067] like Figures 10-13As shown, the elastic first charging component 22 also includes a mounting base 251 and an elastic element 252. The mounting base 251 is elastically mounted on the positioning protrusion 23 via the elastic element 252, and the base station electrode is located on the mounting base 251. The base station electrode is used to conduct current, the mounting base 251 provides a stable mounting foundation for the base station electrode, and the elastic element 252 provides elastic support for the mounting base 251 and the base station electrode. The elastic element 252 can be a spring, sheet metal, etc. When the base station electrode is subjected to pressure, the mounting base 251 undergoes elastic displacement on the positioning protrusion 23 via the elastic element 252, allowing the base station electrode to make close contact with the corresponding device electrode. In other embodiments, the elastic first charging component 22 can be directly formed from the elastic base station electrode, such as a conductive sheet, i.e., elastic contact is achieved through the elastic deformation of the elastic conductive sheet itself. Of course, other forms of elastic charging components can also be provided; any changes to the elastic charging component fall within the protection scope of this disclosure.

[0068] In some embodiments, such as Figure 9 As shown, the first base station electrode 221 and the second base station electrode 222 are provided with multiple protrusions 223, that is, the first base station electrode 221 and the second base station electrode 222 respectively make contact and conduct with the first device electrode 121 and the second device electrode 122 through the protrusions 223. By providing the protrusions 223, the reliability of the contact between the first device electrode 121 and the first base station electrode 221, and the reliability of the contact between the second device electrode 122 and the second base station electrode 222 can be improved.

[0069] In some embodiments, such as Figure 5 and Figure 9 As shown, the cleaning device 10 is equipped with a water inlet 14, and the cleaning base station 20 is equipped with a water supply 24. After the cleaning device 10 and the cleaning base station 20 are positioned and docked, the water inlet 14 and the water supply 24 are connected. By setting the water inlet 14 on the cleaning device 10 and the water supply 24 on the cleaning base station 20, after the cleaning device 10 and the cleaning base station 20 are positioned and docked, the water inlet 14 and the water supply 24 can automatically connect and connect. The cleaning base station 20 can automatically supply water to the cleaning device 10, eliminating the need for the user to manually supply water to the cleaning device 10, greatly improving the convenience of using the cleaning device 10, and thus enhancing the user experience. After the cleaning device 10 and the cleaning base station 20 are positioned and docked, the water inlet 14 and the water supply 24 are connected. That is, the cooperation between the positioning groove 13 and the positioning protrusion 23 provides accurate position guidance for the docking of the water inlet 14 and the water supply 24, improving the docking accuracy of the water inlet 14 and the water supply 24.

[0070] Among them, such as Figure 5 As shown, the water inlet 14 is located in the positioning groove 13; as Figure 9As shown, the water supply nozzle 24 is located on the positioning protrusion 23. During the insertion of the positioning protrusion 23 into the positioning groove 13, it ensures that the water supply nozzle 24 can accurately align with the water inlet nozzle 14, avoiding leakage due to misalignment and ensuring smooth water filling. Simultaneously, the positioning groove 13 provides a relatively enclosed space for the water inlet nozzle 14, reducing collisions between the water inlet nozzle 14 and external objects during daily use of the cleaning equipment 10, thus lowering the risk of damage. For the water supply nozzle 24, being located on the positioning protrusion 23 provides a degree of shielding and protection when not filling water, reducing contamination and damage from the external environment. Furthermore, integrating the water inlet nozzle 14 and the water supply nozzle 24 into the positioning groove 13 and the positioning protrusion 23 respectively makes the structure of the cleaning equipment 10 and the cleaning base station 20 more compact, improving space utilization. It eliminates the need for separate additional installation space and positioning structures for the water inlet nozzle 14 and the water supply nozzle 24, reducing the overall size and structural complexity of the equipment.

[0071] Among them, such as Figure 5 As shown, the first device electrode 121 and the second device electrode 122 are located on both sides of the water inlet 14 along the first direction X; as Figure 9 As shown, the first base station electrode 221 and the second base station electrode 222 are located on both sides of the water supply nozzle 24 along the first direction X. When the cleaning device 10 docks with the cleaning base station 20, under the guidance of the positioning structure, the water inlet nozzle 14 and the water supply nozzle 24 can dock accurately at the same time. That is, the charging and water supply processes can be completed in the same docking action, without the need for separate positioning docking, which simplifies the operation process of the device and improves the working efficiency of the device. For example, after the robot vacuum returns to the cleaning base station 20, charging and water supply can be achieved simultaneously in one docking action, reducing the operation time of the device on the cleaning base station 20, allowing it to be put into the next cleaning task more quickly, thereby improving the user experience.
