Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a water tank assembly, a cleaning base station, and a cleaning system. Background Technology

[0002] After the cleaning robot returns to the cleaning base station after completing its cleaning task on the surface to be cleaned, the cleaning base station usually cleans the cleaning actuators on the cleaning robot to ensure that the cleaning actuators do not breed bacteria and produce odors due to dirt residue, and to ensure the cleaning effect of the surface to be cleaned next time.

[0003] Hair and solid debris removed from the cleaning actuators usually remain in the cleaning tank, requiring regular manual cleaning, which is time-consuming and labor-intensive. Therefore, current cleaning base stations all have a self-cleaning function for the cleaning tank. To save on drive power, the cleaning actuators simultaneously drive the cleaning tank to self-clean during the self-cleaning process. However, because hair and solid debris continuously fall into the cleaning tank during the self-cleaning process, the self-cleaning process of the cleaning actuators becomes ineffective. Over time, this also accelerates the wear of the scraper strips at the bottom of the cleaning tank, reducing their service life. Utility Model Content

[0063] Another objective of this utility model is to provide a water tank assembly that self-cleans after the cleaning actuator has finished self-cleaning.

[0064] To achieve this objective, the present invention adopts the following technical solution:

[0065] A water tank assembly,

[0066] The base of the cleaning base station is detachably equipped with a cleaning tank, and the water tank assembly is located on one side of the cleaning tank;

After self-cleaning, the cleaning actuator moves towards the side of the water tank assembly and connects with it. At this point, the cleaning actuator is in the second position, and its rotation drives the water tank assembly to perform the base station self-cleaning task. Because the base station's self-cleaning occurs after the cleaning actuator's self-cleaning process is completed, rather than occurring simultaneously with it, ineffective self-cleaning of the water tank assembly can be avoided, reducing wear and ensuring service life.

[0088] The inventors of this application conducted a detailed study on cleaning base stations and found that, for cleaning tanks capable of accommodating cleaning actuators for self-cleaning, although there are currently scraper assemblies that automatically clean the bottom of the tank, the scraper assembly often scrapes the bottom of the cleaning tank simultaneously with the self-cleaning of the cleaning actuators. This results in the scraper assembly cleaning the bottom of the tank while the cleaning actuators discharge solid waste or hair into the bottom of the tank. This not only renders the scraper assembly ineffective in cleaning the bottom of the tank but also increases the wear and tear on the scraper assembly. In addition, current scraper assemblies typically use a back-and-forth scraping method, which makes it impossible to gather solid waste or hair in one place. This is not only detrimental to the treatment of solid waste and hair but also leads to poor cleaning results due to the accumulation of solid waste and hair in multiple places.

[0089] Based on the aforementioned problems, the inventors of this application have attempted to configure the scraping mechanism for scraping the bottom of the cleaning tank so that, during its reciprocating movement along the cleaning tank, it only contacts the bottom of the tank to perform the scraping task when moving in one direction, and resets when moving in the other direction, without contacting the bottom of the tank and performing the scraping task. Thus, solid waste and hair deposited at the bottom of the cleaning tank can only be scraped to one side of the tank by the scraping mechanism during the scraping task, facilitating subsequent cleaning and ensuring a good cleaning effect. Furthermore, the inventors of this application utilize the outward swing function of the cleaning actuator. After the cleaning actuator performs self-cleaning, it connects to the drive mechanism via the outward swing. The drive mechanism can transmit the rotational power of the cleaning actuator to the scraping mechanism that performs the cleaning task on the bottom of the cleaning tank, thereby avoiding scraping during the cleaning process of the cleaning actuator, preventing ineffective cleaning of the bottom of the cleaning tank by the scraping mechanism, and preventing premature wear of the scraper blades on the scraping mechanism that contact the bottom of the cleaning tank to perform the scraping task, thus extending the life of the scraping mechanism. Therefore, the following embodiments are obtained.

[0090] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0091] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0092] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0093] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0094] This embodiment provides a cleaning system including a cleaning robot and a cleaning base station. The cleaning robot has cleaning actuators that can come into contact with the surface to be cleaned and perform cleaning tasks. To achieve better cleaning, the cleaning actuators can be extended outwards to clean hard-to-reach areas such as corners, reducing blind spots and ensuring good cleaning results. After completing a cleaning task, emptying wastewater, or needing to recharge, the cleaning robot can move to the cleaning base station and dock to empty its wastewater tank, recharge, perform self-cleaning of the cleaning actuators, and accommodate the robot.

[0095] Specifically, please refer to Figures 1-3As shown, the cleaning base station is equipped with a base 1, and a ramp 4 is provided on one side of the base 1. The cleaning robot can walk along the ramp 4 until it docks with the cleaning base station. The base 1 is equipped with a sewage outlet that docks with the sewage tank on the cleaning robot. After the cleaning robot docks with the cleaning base station, the sewage in the sewage tank is emptied through the sewage outlet. The base 1 is also equipped with a charging structure. After the cleaning robot docks with the cleaning base station, the charging plate on the cleaning robot can abut against the charging structure to charge. The cleaning base station is also equipped with a clean water tank. After the cleaning robot docks with the cleaning base station, the clean water tank can replenish the cleaning fluid in the cleaning water tank on the cleaning robot, and so on.

[0096] Cleaning robots can be mopping robots, sweeping and mopping robots, window cleaning robots, etc., as long as they can perform cleaning tasks on the surfaces to be cleaned. This application does not make any specific limitations.

[0097] In some embodiments of this application, please refer to Figures 1-2 As shown, the base 1 is also equipped with a cleaning tank 11 and a water tank assembly 10 located on one side of the cleaning tank 11. The cleaning actuator has an initial state, a self-cleaning state, and a power supply state. Before the cleaning robot walks on the ramp 4 and docks with the cleaning base station, the cleaning actuator is in the initial state above the cleaning tank 11, at which point the cleaning actuator is at its highest point. After the cleaning robot docks with the cleaning base station, the cleaning actuator falls into the cleaning tank 11. Please refer to... Figures 7-8As shown, the cleaning actuator is housed within the cleaning tank 11 and has at least a first position and a second position. When the cleaning actuator is in the first position, it is in a self-cleaning state. At this time, the cleaning actuator abuts against the cleaning scraper 50 and scraping ribs in the cleaning tank 11. During the rotation of the cleaning actuator, the cleaning scraper 50 can scrape the sewage on the cleaning actuator into the cleaning tank 11, and the scraping ribs can rub the cleaning actuator to achieve self-cleaning, avoiding manual cleaning by the user. This not only reduces the user's labor but also prevents the user from coming into contact with dirt on the cleaning actuator, thus avoiding user annoyance. After the cleaning actuator has completed self-cleaning, it can be swung out to one side of the cleaning tank 11 to the second position connected to the water tank assembly 10. At this time, the cleaning actuator is in a powered state, and the rotation of the cleaning actuator can drive the water tank assembly 10 to perform self-cleaning of the base station. The system automatically cleans up hair and solid waste that falls to the bottom of the cleaning tank 11 during the self-cleaning process of the cleaning actuators. This avoids frequent manual cleaning of the cleaning tank 11 by the user, freeing up user labor, preventing bacterial growth and odors in the cleaning tank 11, and ensuring a good self-cleaning effect on the cleaning actuators. Furthermore, the self-cleaning of the base station in this application is driven by the external docking of the cleaning actuators after the self-cleaning process is completed. This not only saves power components but also avoids simultaneous self-cleaning with the cleaning actuators, preventing hair and solid waste from falling off the cleaning actuators while the water tank assembly 10 is self-cleaning the base station, thus avoiding ineffective self-cleaning of the base station. Because the self-cleaning time of the base station is shortened during this process, excessive wear on the water tank assembly 10 is reduced, thereby ensuring its service life.

[0098] Further, please refer to Figures 1-2 As shown, in some embodiments of this application, the sink assembly 10 includes a drive mechanism 2 and a scraping mechanism 3. The drive mechanism 2 is disposed on one side of the cleaning tank 11, and the cleaning actuator can swing outward to a second position connected to the input end of the drive mechanism 2 after self-cleaning. The scraping mechanism 3 is connected to the output end of the drive mechanism 2, and the drive mechanism 2 can transmit the rotational power of the cleaning actuator to the scraping mechanism 3 to drive the scraping mechanism 3 to reciprocate along the cleaning tank 11 to perform scraping work on the bottom of the cleaning tank 11. The scraping mechanism 3 can slide across the cleaning tank 11, and can cover the entire area of ​​the bottom of the cleaning tank during the back-and-forth movement to reduce cleaning dead corners and ensure good cleaning effect.

[0099] It is understandable that during the reciprocating movement of the scraping mechanism 3, it will inevitably come into contact with the bottom of the cleaning tank 11 to achieve scraping. Therefore, the hair and other solid waste deposited on the bottom of the cleaning tank 11 will be pushed by the scraping mechanism 3 and move with it. When the scraping mechanism 3 moves towards the drive mechanism 2, the hair and solid waste will gather on the side of the bottom of the cleaning tank 11 close to the scraping mechanism 3 under the action of the scraping mechanism 3. When the scraping mechanism 3 moves away from the drive mechanism 2, the remaining hair and solid waste on the bottom of the cleaning tank 11 will gather on the side of the bottom of the cleaning tank 11 away from the scraping mechanism 3 under the action of the scraping mechanism 3. With the back and forth movement of the scraping mechanism 3, the hair and solid waste will accumulate on both sides of the bottom of the cleaning tank 11. The sewage adsorbed in the hair and solid waste will flow along the bottom of the cleaning tank 11 after the water tank assembly 10 has cleaned the bottom of the cleaning tank 11. Compared with the method of accumulating on only one side, this makes the cleaning of the cleaning tank 11 more difficult.

[0100] To address the aforementioned issues, please refer to the following embodiments in this application: Figures 1-2 As shown, the scraping mechanism 3 has a working state and a reset state. In the working state, the scraping mechanism 3 moves towards the drive mechanism and applies a force greater than 0 to the bottom of the cleaning tank 11. At this time, the scraping mechanism 3 is in close contact with the bottom of the cleaning tank. During its movement, it scrapes solid waste such as hair deposited at the bottom of the cleaning tank 11 to the side of the bottom of the cleaning tank 11 closest to the drive mechanism 2. In the reset state, the scraping mechanism moves away from the drive mechanism and applies a force of 0 to the bottom of the cleaning tank. At this time, the scraping mechanism can either be in contact with the bottom of the cleaning tank 11 without applying force, or it can be separated from the bottom of the cleaning tank 11. Thus, the scraping mechanism does not move solid waste such as hair when it moves. Therefore, during the entire scraping process, the scraping mechanism 3 only moves solid waste such as hair when it moves towards the drive mechanism 2, thereby ensuring that solid waste such as hair deposited at the bottom of the cleaning tank 11 is only gathered on the side of the bottom of the cleaning tank 11 closest to the drive mechanism 2. Furthermore, a filter element 12 is provided on the bottom of the cleaning tank 11 near the drive mechanism 2, and a drain outlet 41 is provided on the base 1 below the filter element 12. During the scraping process, solid waste such as hair will be scraped onto the filter element by the scraping mechanism 3. The filter element can prevent solid waste such as hair from entering the drain outlet 41. After the water tank assembly 10 cleans the cleaning tank 11, the sewage adsorbed by solid waste such as hair will also flow out from the filter element 12 into the drain outlet 41 and will not flow along the bottom of the cleaning tank 11, thereby ensuring a good self-cleaning effect of the cleaning tank 11.

[0101] In some embodiments of this application, please refer to Figures 1-5As shown, the scraping mechanism 3 includes a scraping arm 31 and a scraper 33. The scraping arm 31 spans within the cleaning tank 11 and is movably connected to the output end of the drive mechanism 2. The scraper 33 is rotatably mounted on the scraping arm and has a first angle and a second angle. When the scraping mechanism is in the working state, the scraper 33 is located at the first angle, which is in close contact with the bottom of the cleaning tank. When the scraping mechanism is in the reset state, the scraper 33 is located at the second angle, which has a gap with the bottom of the cleaning tank. By adjusting the angle of the scraper 33, the contact between the scraping mechanism and the bottom of the cleaning tank can be determined, resulting in a simple structure. One possible implementation is that the scraping mechanism 3 also includes a rotating shaft 34, which is rotatably mounted on the side of the scraping arm 31 facing the bottom of the cleaning tank 11. The side of the scraper 33 facing away from the bottom of the cleaning tank is connected to the rotating shaft 34. One end of the rotating shaft 34 can be equipped with a rotating shaft motor. When the water tank assembly 10 cleans the cleaning tank 11, the angle of the rotating shaft 34 is adjusted by controlling the rotation of the rotating shaft motor, thereby realizing the angle adjustment of the scraper 33.

[0102] In the embodiments of this application, please refer to Figures 1-5 As shown, another feasible solution for adjusting the angle of the scraper 33 is as follows: Specifically, the scraping mechanism 3 further includes a roller 35, which is interference-fitted onto the end of the rotating shaft 34 away from the output end of the drive mechanism. The cleaning tank 11 has an abutment platform 14 on the side wall away from the output end of the drive mechanism. The roller 35 abuts against the abutment platform 14 and is supported on the abutment platform 14. The roller 35 can roll relative to the abutment platform 14 to drive the rotating shaft 34 to rotate, thereby causing the rotating shaft 34 to drive the scraper 33 to switch between a first angle and a second angle. The roller 35 can also slide relative to the abutment platform 14 to maintain the scraper 33 at the first angle or the second angle. When the scraping mechanism 3 switches from the working state to the reset state, or from the reset state to the initial working state, the roller 35 rotates, driving the rotating shaft 34 to rotate from the second angle to the first angle, or driving the rotating shaft 34 to rotate from the first angle to the second angle. The rotating shaft 34 drives the scraper 33 to switch from a state with a gap from the bottom wall of the cleaning tank 11 to a state of contact with the bottom wall of the cleaning tank 11, or the rotating shaft 34 drives the scraper 33 to switch from contact with the bottom wall of the cleaning tank 11 to a state with a gap. When the scraping mechanism 3 is in the working state, the rotating shaft 34 is maintained at the first angle, and the scraper 33 scrapes the bottom wall of the cleaning tank 11. The roller 35 no longer rolls but slides relative to the contact platform 14. When the scraping mechanism 3 is in the reset state, the rotating shaft 34 is maintained at the second angle, and the scraper 33 always maintains a certain gap with the bottom of the cleaning tank 11. By setting rollers 35 on the rotating shaft 34, the rotation of rollers 35 drives the rotating shaft 34 to adjust the angle. The structure is simpler, the cost is lower, no electricity is required, and the space occupied is smaller.

[0103] Further, please refer to Figures 1-5As shown, in some embodiments of this application, the scraper 33 includes a scraping part 331, a limiting part 332, and a connecting part 333. The connecting part 333 is interference-fitted onto the rotating shaft 34. The scraping part 331 and the limiting part 332 are both located on the side of the connecting part 333 away from the scraping arm 31. There is a suitable angle between the scraping part 331 and the limiting part 332. The length of the scraping part 331 extending in the radial direction of the rotating shaft 34 is longer than the length of the limiting part 332. The side of the scraping part 331 away from the rotating shaft 34 can abut against the bottom wall of the scraping tank and perform the scraping task. When the rotating shaft 34 drives the scraper 33 to rotate to the first angle, the limiting part 332 abuts against the scraping arm 31 to limit the scraper 33 from continuing to rotate. At this time, the roller 35 switches from the rolling state on the abutment platform 14 to the sliding state on the abutment platform 14, thereby ensuring that the rotating shaft 34 no longer rotates and the scraper 33 remains at the first angle, thereby ensuring that the scraping part 331 always abuts against the bottom wall of the cleaning tank 11. The scraping arm 31 has a stop structure 311 on the side facing the drive mechanism 2. When the rotating shaft 34 drives the scraper 33 to rotate from the first angle to the second angle, the scraping part 331 abuts against the stop structure 311. This not only ensures that there is a gap between the scraping part 331 and the bottom of the cleaning tank 11, but also restricts the position of the scraping part 331, preventing the scraping part 331 from rotating too much. This reduces the angle between the first angle and the second angle, shortens the time for the rotating shaft 34 to rotate from the first angle to the second angle, and shortens the switching time of the scraping part 331 from abutting against the bottom of the cleaning tank 11 to having a gap. This prevents the area of ​​the bottom wall of the cleaning tank 11 that the scraping arm 31 drives the scraper 33 to pass through during the switching process of the scraping part 331 from being too large, ensuring that the bottom wall of the cleaning tank 11 can be cleaned sufficiently.

[0104] In another embodiment of this application, please refer to Figure 2 , Figure 8 and Figure 9As shown, another possible structure of the scraping mechanism 3 includes a scraping arm 31 and a scraper 33. The scraping arm 31 is straddling the cleaning tank 11 and is movably connected to the output end of the drive mechanism 2. At least one mounting groove 315 is provided at intervals on the side of the scraping arm 31 facing the bottom of the cleaning tank 11. The scraper abuts against the bottom of the cleaning tank 11, and the scraper 33 is installed in the mounting groove 315. The scraper 33 has a scraping state and a reset state. When the scraper 33 is in the scraping state, the contact force applied by the scraper 33 to the bottom of the cleaning tank 11 is greater than 0, thus enabling it to perform the scraping task on the bottom of the cleaning tank 11. When the scraper 33 is in the reset state, the contact force applied by the scraper 33 to the bottom of the cleaning tank 11 is equal to 0. At this time, although the scraper 33 is in contact with the bottom of the cleaning tank 11, it does not apply any contact force, thus failing to push away solid waste such as hair deposited on the bottom of the cleaning tank 11, leaving the hair and other solid waste in place. The scraper 33 is installed in a one-to-one correspondence with the mounting slot 315, with at least one scraper 33 installed in the corresponding mounting slot 315. That is to say, one or more scraper 33s can be installed on the scraping arm 31 to increase the contact force between the scraping mechanism 3 and the bottom of the cleaning tank 11 when the scraping mechanism 3 is in working state, ensuring a good cleaning effect on the bottom of the cleaning tank 11.

[0105] Furthermore, in some embodiments of this application, please refer to Figure 9As shown, one possible structure of the scraper 33 is as follows: the scraper 33 includes a connecting portion 333 and a scraping portion 331. The connecting portion 333 is detachably disposed within the mounting groove 315. The end of the connecting portion away from the mounting groove 315 is an inclined surface facing away from the drive mechanism. One end of the scraping portion 331 is connected to the tip of the inclined surface, and the other end is inclined towards the drive mechanism 2 and abuts against the bottom of the cleaning tank 11. The width of the portion of the connecting portion 333 installed within the mounting groove 315 is the widest, which ensures the stability of the connection. The width of the scraping portion 331 is smaller than the portion of the connecting portion 333 installed within the mounting groove 315. This not only allows for easy deformation to increase the contact area with the bottom of the cleaning tank 11 to ensure a good cleaning effect, but also provides sufficient strength to prevent excessive deformation, ensuring sufficient contact force with the bottom of the cleaning tank 11. The connection between the connecting part 333 and the scraping part 331 is oriented at an angle away from the drive mechanism 2. This means that when the scraping mechanism 3 is in operation, the friction force exerted by the bottom of the cleaning tank 11 on the scraping part 331 is directed in the opposite direction of the angle. In other words, the angle tends to increase under the action of friction. Under this trend, since the connection between the connecting part 333 and the scraping part 331 has a certain rigidity, although the angle increases, it does not increase too much. This causes the scraping part 331 to rotate slightly counterclockwise, which increases the contact area between the scraping part 331 and the bottom of the cleaning tank 11, thereby increasing the abutment force between the scraping part 331 and the bottom of the cleaning tank 11. This allows solid waste such as hair to be scraped away from the bottom of the cleaning tank 11 as much as possible. When the scraping mechanism is in the reset state, the frictional force exerted by the bottom of the cleaning tank 11 on the scraping part 331 is in the direction of the included angle. This means that the included angle tends to decrease under the action of friction. The scraping part 331 rotates slightly clockwise, further reducing the contact area between the scraping part 331 and the bottom support of the cleaning tank 11. This makes the contact force between the scraping part 331 and the bottom of the cleaning tank 11 almost zero, thus preventing the scraping part 331 from removing solid waste such as hair deposited at the bottom of the cleaning tank 11. By utilizing the structural properties of the scraper itself, unidirectional scraping can be achieved when moving back and forth along the cleaning tank 11. This not only simplifies the structure but also reduces the number of parts and lowers costs.

[0106] It should be noted that, in the embodiments of this application, in order to ensure that the cleaning tank 11 has the maximum volume, the output end of the drive mechanism 2 is located on the side of the cleaning tank 11 away from the slope 4, and the end of the scraping arm 31 away from the slope 4 is movably connected to the output end of the drive mechanism 2. The other end of the scraping arm 31 has a second sliding structure 314, and the cleaning tank 11 has a first sliding structure 13 on the tank wall near the slope. The second sliding structure 314 cooperates with the first sliding structure 13 to reduce the friction of the end of the scraping arm 31 away from the output end of the drive mechanism 2 during sliding, thereby facilitating the scraping arm 31 to move back and forth along the cleaning tank 11.

[0107] In some embodiments of this application, please refer to Figures 4-6 As shown, one possible structure of the drive mechanism 2 includes a transmission assembly 21, a drive wheel 22, and an output component 23. The transmission assembly 21 has an output end and an input end. One end of the drive wheel 22 is connected to the input end; when the cleaning actuator is in the second position, it is connected to the other end of the drive wheel, and the drive wheel rotates with the cleaning actuator. One end of the output component 23 is connected to the output end, and the other end is rotatably disposed on the side of the cleaning tank 11 away from the drive wheel 22. The scraping mechanism 3 is movably connected to the output component 23. In other words, the input end of the drive mechanism 2 is the input end of the transmission assembly 21, and the output end of the drive mechanism 2 is the output end of the transmission assembly 21. The input end of the transmission assembly 21 can be connected to the cleaning actuator via the drive wheel 22, and the output end of the drive mechanism 2 is connected to the scraping mechanism 3 via the output component 23. After completing self-cleaning, the cleaning actuator swings outward and connects to the drive wheel 22, driving the drive wheel 22 to rotate. The drive wheel 22 inputs the rotational power of the cleaning actuator to the transmission assembly 21, which transmits the power and outputs it through the output component 23, driving the scraping mechanism 3 to move along the cleaning tank 11. The transmission assembly 21 can be a structure of multiple meshing gears or a structure composed of a belt and pulley, as long as it can transmit force, this application does not make specific limitations. The output component can be a lead screw. The scraping mechanism 3 also includes a power component 32, which is located at the end of the scraping arm 31 away from the roller 35. The power component 32 can be a lead screw nut, which meshes with the lead screw to connect the power component and the output component 23. The rotation of the lead screw can drive the lead screw nut to move along the lead screw. Of course, the structure of the output component 23 and the structure of the power component 32 can also be other, as long as the output component 23 can be connected to the power component 32, and the rotation of the power component 32 can drive the output component 23 to move along the power component 32, this application does not make specific limitations.

[0108] Please refer to Figures 1-6As shown, since the cleaning actuator docks with the drive wheel 22 via an outward swing mechanism, in this embodiment, the end of the cleaning actuator can have a first docking structure, while the side of the drive wheel 22 facing away from the transmission assembly 21 has a second docking structure. The first docking structure can be inserted into the second docking structure to connect the cleaning actuator and the drive wheel 22. One of the first and second docking structures can be a groove with a certain shape, such as a plum blossom-shaped groove, a cross-shaped groove, a straight groove, or a triangular groove. The other is a protrusion that matches the groove, such as a plum blossom-shaped protrusion, a cross-shaped protrusion, a straight protrusion, or a triangular protrusion, as long as it can match the groove. However, with this solution, the drive wheel 22 and the cleaning actuator need to have a specific docking angle when docking with the first and second docking structures. Therefore, the docking accuracy requirement is relatively high. In addition, the strength of the first and second docking structures needs to be sufficiently strong; otherwise, they are easily damaged during force transmission.

[0109] In some other embodiments of this application, the end of the cleaning actuator has a slot. When the cleaning actuator swings outward, the drive wheel 22 can be inserted into the slot and abut against the slot wall. During the rotation of the cleaning actuator, the drive wheel 22 is driven to rotate by the friction between the cleaning actuator and the drive wheel 22. This method can not only achieve sufficient force transmission strength, but also reduce the accuracy requirements of docking, ensuring that the cleaning actuator can be smoothly connected to the drive wheel 22.

[0110] During the process of the cleaning actuator driving the drive wheel 22 to rotate, the greater the friction between the cleaning actuator and the drive wheel 22, the more rotation of the cleaning actuator the drive wheel 22 can absorb. Therefore, please refer to... Figures 4-6 As shown, in some embodiments of this application, the outer periphery of the drive wheel 22 is provided with a plurality of force transmission structures 222 to increase the transmission friction, thereby increasing the friction between the drive wheel 22 and the cleaning actuator. The force transmission structure 222 may be ribs or protrusions spaced apart on the outer periphery of the drive wheel 22. The material of the ribs or protrusions may be rubber or other materials with a certain amount of compressibility that can increase friction, as long as it can increase the friction between the drive wheel 22 and the cleaning actuator. The specific shape and material of the force transmission structure 222 are not specifically limited in this application.

[0111] Setting the cleaning actuator and drive wheel 22 to be an interference fit is a good solution to increase the friction between the cleaning actuator and drive wheel 22. However, this will cause the drive wheel 22 to interfere with the cleaning actuator when it first enters the slot, which is not conducive to the drive wheel 22 entering the slot.

[0112] To solve the above problems, please refer to Figures 4-6As shown in some embodiments of this application, a guide structure 221 is provided at the end of the drive wheel 22 facing away from the transmission assembly 21. The guide structure 221 can guide the drive wheel 22 into the slot, increasing the probability of successful docking between the drive wheel 22 and the cleaning actuator. The guide structure 221 can be a tapered shape provided at the end of the drive wheel 22. The tapered guide structure 221 makes the initial diameter of the drive wheel 22 entering the slot relatively small, thereby facilitating the entry of the drive wheel 22 into the slot. Furthermore, during the docking process, there will inevitably be some error between the drive wheel 22 and the cleaning actuator. Even if the ends of the drive wheel 22 and the cleaning actuator are not precisely aligned, the tapered guide structure 221 can still guide the drive wheel 22 into the slot. Therefore, the guide structure 221 also has the function of eliminating the influence of error, ensuring the probability of successful docking between the drive wheel 22 and the cleaning actuator.

[0113] In other embodiments of this application, please refer to Figure 8 As shown, the cleaning actuator moves to the outer periphery of the second position and abuts against the force transmission structure 222. The rotation of the cleaning actuator can drive the drive wheel 22 to rotate together by applying friction to the force transmission structure 222. The guide structure 221 can prevent the cleaning actuator from interfering with the drive wheel 22 during its outward swing from the first position to the second position, and guide the cleaning actuator to move to the second position where it can abut against the force transmission structure 222 on the outer periphery of the drive wheel 22.

[0114] In some embodiments of this application, please refer to Figures 4-6 As shown, the filter element 12 can also be detachably snapped onto the bottom of the cleaning tank 11 using a snap-fit ​​mechanism. After the cleaning tank 11 has finished self-cleaning, the filter element 12 can be removed from the bottom of the cleaning tank 11, and solid waste such as hair can be cleaned off the filter element 12. After cleaning the filter element 12, it can be reinstalled. The upper surface of the filter element 12 is lower than or flush with the surface of other parts of the bottom wall of the cleaning tank 11, thereby ensuring that the scraping mechanism 3 can scrape solid waste such as hair onto the scraping mechanism 3.

[0115] Further, please refer to Figure 6As shown in some embodiments of this application, the base 1 is provided with a disassembly groove, and the cleaning groove 11 is detachably disposed on the disassembly groove. The detachability can be achieved by having a slot on the periphery of the disassembly groove and a corresponding locking block on the periphery of the cleaning groove 11. The cleaning groove 11 can be installed in the disassembly groove by engaging the locking block in the slot, or the cleaning groove 11 can be removed from the disassembly groove by removing the locking block. Alternatively, the connection between the cleaning groove 11 and the disassembly groove can be achieved by having an installation step inside the disassembly groove. The cleaning groove 11 can be placed on the installation step for installation, and removed from the installation step for disassembly. As long as a detachable connection between the cleaning groove 11 and the disassembly groove can be achieved, this application does not impose specific limitations. After the cleaning groove 11 is disassembled, it can be thoroughly cleaned before being reinstalled, thereby ensuring the cleanliness of the cleaning groove 11. A drain outlet 41 is provided on the bottom wall of the disassembly tank, located at the filter element 12. The filter element 12 covers the drain outlet 41, allowing wastewater to drain directly from the filter element 12 and exit through the drain outlet 41 without lingering at other locations on the bottom of the disassembly tank. In the embodiment of this application, the drain outlet 41 is the lowest point of the bottom wall of the disassembly tank, ensuring that all wastewater flows out from the drain outlet 41, preventing wastewater from lingering at the bottom of the disassembly tank.

[0116] Application Scenario 1:

[0117] After completing its cleaning task, the cleaning robot returns to the cleaning base station. While moving along ramp 4, the cleaning actuator is elevated due to the ramp's angle. As the robot approaches the base station, the actuator is positioned above the cleaning tank 11. Once the robot reaches its designated position and docks with the base station, it is no longer affected by the ramp's angle. The actuator then falls into the cleaning tank 11. Its rotation allows it to continuously contact the cleaning scraper 50 and ribs within the tank for self-cleaning. After self-cleaning, the actuator swings the robot out to one side of the tank and docks with the drive mechanism. The actuator then rotates to drive the mechanism to clean the bottom of the cleaning tank 11.

[0118] Application Scenario 2:

[0119] After cleaning is completed, the cleaning actuator swings out toward one side of the cleaning tank 11 and abuts against the drive wheel 22. The rotation of the cleaning actuator drives the drive wheel 22 to rotate through the friction between the cleaning actuator and the drive wheel 22. The drive wheel 22 inputs the power of the rotation of the cleaning actuator to the transmission component 21. The transmission component transmits the power to the output component 23. The output component 23 drives the power component 32 to move along the output component 23, so that the power component 32 drives the scraping arm 31 to move along the cleaning tank.

[0120] When the scraping arm 31 moves toward the drive mechanism 2, the scraper on the scraping arm abuts against the bottom wall of the cleaning tank 11 to scrape the hair or solid waste deposited on the bottom wall of the cleaning tank 11 toward the filter element, thereby scraping the bottom of the cleaning tank 11 and causing solid waste or hair to accumulate at the filter element.

[0121] When the scraping arm 31 is located on the side of the cleaning tank 11 close to the drive mechanism 2, the cleaning actuator rotates in the opposite direction to drive the scraping arm 31 to move toward the side away from the drive mechanism 2. During this process, there is a gap between the scraper 33 and the bottom wall of the cleaning tank 11, and the scraping task is not performed to avoid scraping hair or solid waste onto the side of the cleaning tank 11 away from the drive mechanism 2, so as to ensure that hair or solid waste only accumulates on the filter element 12.

[0122] After the cleaning tank 11 is cleaned, the user can remove the filter element 12 from the cleaning tank 11 to clean hair or solid waste, and then put the filter element 12 back in.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
