[0029] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0030] To address the aforementioned problems, this utility model proposes a robotic cleaning device.

[0031] Reference Figure 1 In one embodiment, the robotic cleaning device includes: Base 10; A first cleaning component 20 is connected to the base 10. The first cleaning component 20 is used to accommodate the robot liquid cleaning module and introduce cleaning fluid to clean the robot liquid cleaning module. The second cleaning component 30 is detachably connected to the first cleaning component 20. The second cleaning component 30 is used to accommodate the robot solid cleaning module and to clean the robot solid cleaning module.

[0032] In this embodiment, the base 10 can fix the robot cleaning device to other devices or fasteners, preventing the robot cleaning device from shifting due to external forces. This ensures the stability of the robot cleaning device during docking with the robot and the stability of the robot's cleaning module during cleaning. Since the robot has a liquid cleaning module and a solid cleaning module, the robot cleaning device in this embodiment can be equipped with a first cleaning component 20 and a second cleaning component 30.

[0033] The robot's liquid cleaning module can be a squeegee, mop, or absorbent pad, etc., that absorbs liquid. Since the robot's liquid cleaning module easily accumulates stains when absorbing wastewater from the ground, in this embodiment, the first cleaning component 20 can soak the liquid cleaning module in a cleaning solution to dissolve and remove oil stains. The cleaning solution can be water, hot water, water with added detergent, or other liquids with cleaning properties. Furthermore, the specific shape and size of the base 10 can be designed accordingly based on the shape of the first cleaning component 20. The robot's solid cleaning module can be a roller brush, disc brush, roller, dust mop, or vacuum rake, etc., that cleans solid stains on the ground. Since the robot's solid cleaning module is also easily covered with solid stains when cleaning ground stains, in this embodiment, the stains on the solid cleaning module can be cleaned by friction and brushing, specifically by using friction to remove the adhering substances from the surface of the solid cleaning module. It is understandable that the second cleaning component 30 and the first cleaning component 20 can be detachably connected by means of buckles, clips, pins, etc. The detachable connection between the second cleaning component 30 and the first cleaning component 20 allows the extra cleaning components to be disassembled when the robot only has a solid cleaning module or a liquid cleaning module, reducing the space occupied by the robot cleaning device, and also making it convenient to repair and clean the cleaning components separately.

[0034] The robot cleaning device of this utility model is equipped with a first cleaning component 20 and a second cleaning component 30 corresponding to the robot's liquid cleaning module and solid cleaning module. After the robot and the robot cleaning device are docked, the robot's liquid cleaning module and solid cleaning module can be cleaned separately. At the same time, cleaning multiple cleaning modules of the robot can improve the cleaning efficiency of the robot's cleaning modules.

[0035] Reference Figure 1 In one embodiment, the robotic cleaning device further includes: A water guide channel 40 is provided, with its first end disposed on the second cleaning component 30 and its second end disposed on the first cleaning component 20. The water guide channel 40 is used to allow liquid to flow between the first cleaning component 20 and the second cleaning component 30.

[0036] In this embodiment, a water guide channel 40 is provided between the second cleaning component 30 and the first cleaning component 20, allowing liquid in the first cleaning component 20 to flow to the second cleaning component 30, or vice versa. For example, when cleaning fluid is introduced into the first cleaning component 20 to clean the robot's liquid cleaning module, the cleaning fluid can also flow into the second cleaning component 30 through the water guide channel 40. The cleaning components in the second cleaning component 30 can then use the cleaning fluid to clean the robot's solid cleaning module, improving cleaning efficiency. Alternatively, after the second cleaning component 30 has cleaned the robot's solid cleaning module, the liquid can flow into the first cleaning component 20 through the water guide channel 40, where the robot's liquid cleaning module can absorb the liquid from the first cleaning component 20. Therefore, in this embodiment, a water guide channel 40 is provided between the first cleaning component 20 and the second cleaning component 30, allowing liquid to circulate between them and improving the cleaning efficiency of the robot's cleaning module.

[0037] Reference Figure 2 and Figure 3 In one embodiment, the robotic cleaning device further includes: Fixed connector 51 is used to fix the first cleaning component 20 and the second cleaning component 30; A water-guiding fixing component 52 is disposed on the first cleaning component 20; The fixing member 53 is used to fix the second end of the water guide channel 40 onto the water guide fixing member 52.

[0038] In this embodiment, the fixing connector 51 can be a hook, screw, bolt, or other similar device. By fixing the first cleaning component 20 and the second cleaning component 30 together with the fixing connector 51, the overall stability of the robot cleaning device can be improved. Multiple fixing connectors 51 can be provided, and the specific number can be determined according to the actual structural size of the first cleaning component 20 and the second cleaning component 30. The water guiding fixing component 52 and the fixing pressure component 53 are used to fix the second end of the water guiding channel 40. First, the water guiding fixing component 52 is placed on the first cleaning component 20 to provide a stable support point for the water guiding channel 40, ensuring its accurate position and preventing liquid splashing or drainage failure caused by shaking or displacement during water flow. The fixing pressure component 53 provides a reliable connection method. When the second end of the water guiding channel 40 is placed on the water guiding fixing component 52, the fixing pressure component 53 can further fix the second end of the water guiding channel 40 to the water guiding fixing component 52, preventing the water guiding channel 40 from falling off. This increases the stability of the connection between the water guiding channel 40, the first cleaning component 20, and the water guiding fixing component 52. This ensures that the water guide channel 40 will not easily detach from the water guide fixing component 52 during equipment operation, guaranteeing the stability and integrity of the entire water guide system. The water guide fixing component 52 and the fixing pressure component 53 can be made of silicone or plastic materials. Silicone or plastic materials have good elasticity and sealing performance, which can effectively prevent liquid leakage from the connection and ensure that the liquid in the first cleaning component 20 will not overflow; and silicone or plastic materials have good shock absorption performance, which can absorb vibration and impact, reducing damage to the first cleaning component 20 and the water guide fixing component 52 during use.

[0039] Reference Figure 4 In one embodiment, the first cleaning component 20 includes: The first cleaning seat 21 is connected to the base 10; The first cleaning tank 22 is disposed on the first cleaning seat 21; An ultrasonic cleaning component 23 is disposed in the first cleaning tank 22. The ultrasonic cleaning component 23 is used to emit ultrasonic waves to clean the robot's liquid cleaning module.

[0040] In this embodiment, the first cleaning component 20 consists of a first cleaning seat 21, a first cleaning tank 22, an ultrasonic cleaning component 23, and a lifting member. The first cleaning tank 22 can be fixedly mounted on the first cleaning seat 21 to increase stability; alternatively, the first cleaning tank 22 can be detachably mounted on the first cleaning seat 21 to increase flexibility. The ultrasonic cleaning component 23 uses ultrasonic waves to clean solid dirt adsorbed on the robot's cleaning module. Ultrasonic cleaning is a cleaning technology that uses high-frequency sound waves to generate microbubbles in a liquid. These bubbles rapidly form and collapse in the liquid, generating powerful shock waves, thereby effectively removing dirt, grease, dust, and other contaminants from the surface of objects. The ultrasonic cleaning component 23 can be made of ceramic sheets, piezoelectric polymers, or metal materials. These materials can convert electrical energy into mechanical vibrations, thereby generating ultrasonic waves. After the robot completes docking and the robot cleaning device begins cleaning the robot's liquid cleaning module, the ultrasonic cleaning component 23 can receive the working signal output by the controller and emit ultrasonic waves to clean the robot's liquid cleaning module. The controller can be located in an external workstation and electrically connected to the ultrasonic cleaning component 23 via wires. After the robot completes docking, the controller receives the corresponding docking signal, at which point the controller can output a working signal to the ultrasonic cleaning component 23. Alternatively, the user can output a control signal to the controller via wireless communication, causing the controller to output a working signal to the ultrasonic cleaning component 23. By introducing a cleaning fluid, it can be combined with ultrasonic waves to clean the robot's cleaning module. The cleaning fluid can amplify the cavitation effect of ultrasonic cleaning, and the cavitation effect of ultrasonic cleaning can also accelerate the dissolution and removal of oil stains by the cleaning fluid, resulting in higher cleaning efficiency.

[0041] In one embodiment, the first cleaning component 20 is provided with a first water inlet and a first water outlet.

[0042] In this embodiment, the first water inlet and the first water outlet on the first cleaning component 20 can be specifically set on the first cleaning tank 22 of the first cleaning component 20. The first water inlet can be used to introduce cleaning fluid to clean the robot's liquid cleaning module. It is understood that the wastewater generated after cleaning the robot's liquid cleaning module can be sucked away by the robot's liquid cleaning module. In this embodiment, the first water outlet is set on the first cleaning tank 22 so that the wastewater can be discharged through the first water outlet after cleaning, thus avoiding the robot's liquid cleaning module failing to automatically suck away the wastewater or not sucking away all the wastewater. The first water inlet and the first water outlet on the first cleaning tank 22 are not shown in the figure, and their specific positions, numbers, and sizes can be determined according to the actual situation and user needs.

[0043] In one embodiment, the first water inlet provided on the first cleaning tank 22 can be connected to an external workstation to introduce cleaning fluid from the workstation.

[0044] In another embodiment, the first inlet can be connected to the robot to introduce cleaning fluid from the robot.

[0045] In another embodiment, the first inlet may also be connected to other devices storing cleaning fluid via a pipe, thereby introducing cleaning fluid.

[0046] Reference Figures 4 to 6 In one embodiment, the second cleaning component 30 includes: The second cleaning seat 31 is connected to the first cleaning component 20, and the second cleaning seat 31 has a receiving cavity; The second cleaning tank 32 is detachably assembled into the receiving cavity and is in clearance fit with the receiving cavity; A cleaning brush 33 is detachably mounted in the second cleaning tank 32, and the cleaning brush 33 is used to clean the robot's solid cleaning module; A lifting component 34 is disposed on the second cleaning seat 31, and the lifting component 34 is used to lift the robot. The elastic element 35 is connected to the bottom of the second cleaning tank 32 and the second cleaning seat 31 respectively, so as to elastically expand and contract up and down when the second cleaning tank 32 is pressed and depressurized.

[0047] In this embodiment, the second cleaning seat 31 is used to support and accommodate the second cleaning tank 32, which is used to assemble the cleaning brush 33, and the cleaning brush 33 is used to clean the solid cleaning module. The bottom of the second cleaning tank 32 is connected to the second cleaning seat 31 through an elastic member 35, so that when the second cleaning tank 32 is compressed, the elastic member 35 can be compressed, thereby reducing the height of the second cleaning tank 32 and avoiding interference between the second cleaning tank 32 and the cleaning brush 33 in the second cleaning tank 32 during docking with the robot; at the same time, when the second cleaning tank 32 is in a depressurized state, the second cleaning tank 32 can be restored to its initial height under the action of the elastic member 35.

[0048] The elastic element 35 connects the second cleaning groove 32 and the second cleaning seat 31. When the robot is not docked with the robot cleaning device, the second cleaning seat 31 is in a depressurized state. When the robot docks with the robot cleaning device, the robot's rollers roll onto the second cleaning groove 32, and the second cleaning groove 32 becomes compressed. The elastic element 35 is then compressed, and the height of the second cleaning groove 32 decreases, allowing the robot to dock with the robot cleaning device. When the robot docks with the robot cleaning device, the robot's rollers disengage from the second cleaning seat 31, the elastic element 35 returns to its elastic deformation, and the second cleaning groove 32 returns to its depressurized state. The height of the second cleaning groove 32 is then restored, allowing it to interfere with the solid cleaning module at the bottom of the robot. Thus, as the robot starts, the solid cleaning module rotates, and the relative interference friction between the solid cleaning module and the cleaning brush 33 achieves self-cleaning of the solid cleaning module. The specific location of the elastic element 35 can be found in [reference needed]. Figure 5 .

[0049] Because the second cleaning tank 32 and the receiving cavity are fitted with a clearance, and the elastic element 35 is elastic, when the second cleaning tank 32 is under pressure, it will not only move vertically, but also float freely within a certain direction due to the change in the direction of the force exerted on it by the robot as the robot moves. This allows the cleaning brush 33 to float freely within a certain range. The solid cleaning modules at the bottom of the robot are arranged in pairs; see reference... Figure 6 Taking the solid cleaning module with roller brush 100 as an example, the robot has two relatively rotating roller brushes 100 at its bottom, with the rotation direction of the two roller brushes 100 facing the central area. Because the cleaning brush 33 is designed to have a certain floating range in the up-down, forward-backward, and left-right directions, when the two roller brushes 100 rotate, the friction generated between the roller brushes 100 and the cleaning brush 33 will drive the cleaning brush 33 to move closer to the central area between the two roller brushes 100, thereby increasing the contact area between the cleaning brush 33 and the roller brushes 100, and thus increasing the friction. This is beneficial for improving the removal efficiency of the deposits on the surface of the roller brush 100, achieving a better cleaning effect. Alternatively, the robot has a single roller brush 100 at its bottom, which can also rub against the cleaning brush 33 to remove the deposits on the surface of the roller brush 100.

[0050] This design assembles a second cleaning groove 32 within the receiving cavity of the second cleaning seat 31, and installs a cleaning brush 33 within the second cleaning groove 32. A floating cleaning brush 33 is provided by the connection between the bottom of the second cleaning groove 32 and the second cleaning seat 31 via an elastic element 35. Furthermore, through a dual-solid cleaning module structure rotating in opposite directions, the cleaning brush 33 automatically adheres to the solid cleaning modules using the friction generated during their rotation, achieving effective cleaning of the bristles and surface of the solid cleaning modules without manual disassembly, thus improving maintenance efficiency. The cleaning brush 33 has floating spaces in the vertical and horizontal directions, allowing it to automatically adjust its position and enter the cleaning area between the two solid cleaning modules under friction, increasing the contact area and friction, thereby enhancing the cleaning effect. Simultaneously, based on the elastic expansion and contraction deformation of the elastic element 35, the cleaning brush 33 achieves height adjustment, passively adjusting its height according to the docking status between the robot and the robot cleaning device, avoiding obstruction of the robot's normal docking path, and ensuring that the self-cleaning function of the solid cleaning module and the robot docking process do not interfere with each other.

[0051] Furthermore, to prevent interference between the robot's solid cleaning module and liquid cleaning module and the first cleaning tank 22 and the second cleaning tank 32 during operation, a lifting component 34 can be installed on the second cleaning tank 32 to elevate the robot and allow it to dock with the robot cleaning device. This avoids interference between the robot's solid cleaning module and liquid cleaning module and the first cleaning tank 22 and the second cleaning tank 32, and also reduces the footprint of the second cleaning component 30. The height of the lifting component 34 can be set according to actual conditions and user needs; if the height is too high, the robot will be unstable and the second cleaning component 30 will not be able to effectively clean the robot's solid cleaning module, or if the height of the lifting component 34 is too low, the robot's solid cleaning module and liquid cleaning module will interfere with the first cleaning tank 22 and the second cleaning tank 32.

[0052] Additionally, refer to Figure 4 The second cleaning unit 30 also includes a ramp in its second cleaning seat 31 structure. The ramp serves as a guide during the docking process between the robot and the robot cleaning device. The robot can dock with the robot cleaning device via the ramp, or the robot can leave the robot cleaning device via the ramp. The inclination angle of the ramp can be set according to the actual situation and user needs.

[0053] In one embodiment, the second cleaning component 30 is provided with a second water inlet and a second water outlet.

[0054] In this embodiment, the second water inlet and the second water outlet on the second cleaning component 30 can be specifically set on the second cleaning tank 32 of the second cleaning component 30. The second water inlet can also be used to introduce cleaning fluid, which, in conjunction with the cleaning brush, cleans the robot's solid cleaning module, improving cleaning efficiency. It is understood that the wastewater generated after cleaning the robot's solid cleaning module can flow through the water guide trough 40 to the first cleaning component 20, and then be sucked away by the robot's liquid cleaning module. In this embodiment, a second water outlet is provided on the second cleaning tank 32, which allows the wastewater to be discharged after cleaning, simplifying the process. The second water inlet and the second water outlet on the second cleaning tank 32 are not shown in the figure; their specific location, number, and size can be determined according to actual conditions and user needs.

[0055] For the liquid introduction source of the second water inlet provided on the second cleaning tank 32, the liquid introduction source of the first water inlet provided on the first cleaning tank 22 in the above embodiment can be referred to.

[0056] This utility model also proposes a robotic cleaning workstation.

[0057] Reference Figure 4 and Figure 7 In one embodiment, the robotic cleaning workstation includes a fixed workstation 200 and a robotic cleaning device 300 as described above, wherein the fixed workstation 200 is connected to a base 10 in the robotic cleaning device 300.

[0058] It is understood that, since the robot cleaning device 300 described above is used in the robot cleaning workstation of this utility model, the embodiments of the robot cleaning workstation of this utility model include all the technical solutions of all embodiments of the robot cleaning device 300 described above, and the technical effects achieved are exactly the same, so they will not be repeated here.

[0059] In this embodiment, physical docking structures can also be provided on the fixed workstation 200 and / or the robot cleaning device 300. Corresponding physical docking structures can also be provided on the robot body and / or cleaning modules (liquid cleaning modules or solid cleaning modules). During the docking process between the robot and the robot cleaning workstation, physical docking structures provide physical limits, ensuring that the robot's cleaning modules can accurately dock with the first cleaning component 20 and the second cleaning component 30 of the robot cleaning device 300, without interfering with other structures of the robot cleaning device 300, thus ensuring the stability of the overall structure. The physical docking structure can be a guide rail, slider, positioning pin, limit block, or snap-fit ​​structure, etc.

[0060] In one embodiment, the fixed workstation 200 has a water pipe connected to the robot cleaning device 300, and the fixed workstation 200 is used to inject cleaning fluid through the water pipe into the first cleaning component 20 and the second cleaning component 30 of the robot cleaning device 300.

[0061] In this embodiment, the fixed workstation 200 can be connected to municipal tap water and sewers via water pipes, and can also be equipped with a water tank 230 to store cleaning fluid, and connected to the power grid for power supply. Additionally, a heating device 220 can be installed in the fixed workstation to heat the cleaning fluid in the water tank 230; using heated cleaning fluid increases cleaning efficiency. The fixed workstation 200 can inject the cleaning fluid into the first cleaning component 20 and the second cleaning component 30 of the robotic cleaning device 300 via water pipes, or it can inject it into the robot itself. This enables the supply of water and power to both the robotic cleaning device 300 and the robot. The fixed workstation 200 can be permanently installed in one location, facilitating automatic pathfinding and return after the robot completes its cleaning work, and its fixed location ensures stability during the robot docking process.

[0062] Reference Figure 7 In one embodiment, the robotic cleaning workstation further includes: A control board 210 is disposed within the fixed workstation 200. A control circuit 211 is disposed on the control board 210. The control circuit 211 is electrically connected to the first cleaning component 20 in the robot cleaning device 300. The control circuit 211 is used to output working signals to the first cleaning component 20.

[0063] In this embodiment, the control board 210 in the fixed workstation 200 can be a printed circuit board for integrating electronic components. A control circuit 211 can be installed on the control board 210, electrically connected to the ultrasonic cleaning component 23 in the first cleaning component 20. The control circuit 211 can be composed of electronic components such as a control chip, switching transistors, capacitors, resistors, and diodes. The control circuit 211 can also integrate power supply functions; by controlling the switching transistors to turn them on and off, it can control the fixed workstation 200 to power external drives and devices. After the robot docks with the fixed workstation 200, the control circuit 211 in the fixed workstation 200 can output a working signal to the ultrasonic cleaning component 23 to control its operation, thus achieving ultrasonic cleaning. Furthermore, the control circuit 211 can also be connected to the heating device 220 to control its operation, heating the cleaning fluid in the water tank 230 to improve cleaning efficiency. The heating device can be a resistance heater or a PTC heater, etc.

[0064] Reference Figure 7In one embodiment, the first cleaning component 20 in the robot cleaning device 300 includes a liquid level detection mechanism 310, which is used to detect the liquid level in the first cleaning component 20 and output a corresponding liquid level detection signal. The robotic cleaning workstation also includes: A liquid level detection circuit 212 is disposed on the control board 210. The liquid level detection circuit 212 is connected to the liquid level detection mechanism 310. The liquid level detection circuit 212 is used to receive the liquid level detection signal output by the liquid level detection mechanism 310, and output a stop water adding signal when the liquid level in the cleaning seat of the robot cleaning device 300 is detected to be higher than the safe height according to the liquid level detection signal.

[0065] In this embodiment, the liquid level detection mechanism 310 can be composed of multiple liquid level sensors. These sensors detect the liquid level within the first cleaning component 20, specifically the liquid level in the first cleaning tank 22 within the first cleaning component 20, and then output a corresponding liquid level detection signal to the liquid level detection circuit 212 on the control board 210. The liquid level detection circuit 212 outputs the liquid level detection signal to the processor on the control board 210. The processor converts the liquid level detection signal into a digital signal and then determines the liquid level in the first cleaning tank 22. When the liquid level in the first cleaning tank 22 is higher than the safe height, it indicates that water is about to overflow. At this time, a stop water supply signal can be output to stop adding water to the first cleaning tank 22. For example, when adding water through a water pipe, the processor controls the valve on the water pipe to close, thereby stopping the water supply; or when adding water through a robot, the processor can output an electrical signal to the robot to stop the robot from adding water. The safe liquid level in the first cleaning tank 22 can be set according to actual conditions and user needs. Specifically, this embodiment can employ a capacitive liquid level detection scheme or an electrode-type liquid level detection scheme. The capacitive level detection scheme uses a capacitance detection chip to sense the capacitance value in real time. The liquid level detection circuit 212 of the control board 210 periodically acquires the capacitance value through the I2C interface. When the capacitance value is greater than the set value, a stop water addition signal is output to stop adding water to the first cleaning tank 22. The electrode-based liquid level detection scheme arranges conductive electrodes at the corresponding liquid level height. Based on the principle that conductive electrodes conduct when in contact with water, a corresponding liquid level detection circuit 212 is designed on the control board 210 to detect the voltage between the electrodes, thus realizing the liquid level detection function. The liquid level detection circuit 212 can be composed of electronic components such as inductors, capacitors, and resistors.

[0066] In one embodiment, the fixed workstation 200 includes a housing and a platform, the housing being disposed on the platform and the platform being connected to the base 10 in the robot cleaning device 300; wherein, the housing is a plastic housing and the platform is a metal platform; or, the housing is a metal housing and the platform is a metal platform.

[0067] In this embodiment, the platform is connected to the base 10 of the robot cleaning device 300, which connects the fixed workstation 200 to the robot cleaning device 300, increasing the stability of the overall mechanism, ensuring the stability of the robot docking process, and ensuring stability when cleaning the robot's cleaning module. The plastic shell reduces the overall weight of the fixed workstation 200, facilitating handling and installation, and provides insulation, effectively preventing safety hazards caused by electrical component leakage. The plastic shell also has a certain degree of elasticity, absorbing and buffering vibrations, reducing noise and vibration transmission generated by the fixed workstation 200 during operation. A metal shell, on the other hand, effectively shields electromagnetic interference, preventing interference from external electromagnetic signals to the internal electronic components of the fixed workstation 200, and can withstand greater external impacts and pressures, making it less prone to damage. The metal platform increases the overall weight of the fixed workstation 200, lowers its center of gravity, and makes the workstation more stable on the ground, less prone to tipping or wobbling. Furthermore, when the robot returns to the fixed workstation 200 for charging, cleaning, or other operations, it exerts pressure on the platform. The metal platform has high strength and load-bearing capacity, capable of withstanding the weight of the cleaning robot and the impact forces generated during operation, and is not easily deformed or damaged. The specific materials for the shell and platform can be selected based on actual conditions and user needs.
