[0016] The following description provides more specific details to allow for a more thorough understanding of the technical solutions provided by this disclosure. However, it will be obvious to those skilled in the art that the technical solutions provided by this disclosure can be implemented even if one or more of these details are omitted.

[0017] It should be noted that the terms used herein are used to describe specific embodiments and are not intended to limit the exemplary embodiments of this disclosure. Where used herein, singular terms include plural forms unless otherwise specified in the context. Furthermore, where the terms “includes” and / or “compose” are used herein, they refer to the presence of such features, wholes, steps, operations, elements and / or assemblies, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, elements, assemblies and / or combinations thereof. Now, exemplary embodiments of this disclosure will be described in more detail with reference to the attached drawings. However, these exemplary embodiments can be implemented in a variety of different forms and are not limited to the embodiments described herein. These embodiments are used to make the disclosure more thorough and complete and to fully convey the concepts of these exemplary embodiments to those skilled in the art.

[0018] As shown in Figures 1 to 16, embodiments of the present disclosure provide a base station 200 and a cleaning robot system, where the cleaning robot system comprises a self-propelled cleaning machine 100 and a base station 200, i.e., the base station 200 is used in combination with the self-propelled cleaning machine 100.

[0019] Furthermore, as shown in Figures 1 and 2, the self-propelled cleaning machine 100 comprises a machine body 110, a sensing system 120, a control module, a drive system 140, a cleaning system 150, an energy system, and a man-machine interactive system 170. Note that the self-propelled cleaning machine 100 may be an automatic cleaning device or another self-propelled cleaning machine 100 that meets the requirements. The self-propelled cleaning machine 100 is a device that automatically performs cleaning operations in an area to be cleaned without user intervention. Here, when the self-propelled cleaning machine 100 starts work, it departs from the base station 200 and performs the cleaning task. When the self-propelled cleaning machine 100 completes the cleaning task or stops the cleaning task as necessary, it returns to the base station 200 for operations such as charging, and / or rehydrating, and / or washing, and / or dust collection.

[0020] As shown in Figure 1, the device body 110 includes a front portion 111 and a rear portion 112 and has an approximate circular shape. It may also have other shapes, such as an approximate D-shape with a rectangular front and a circular rear, or a rectangular or square shape with rectangular front and rear.

[0021] As shown in Figure 1, the sensing system 120 includes a position determination device 121 located on the main body 110, a collision sensor and a short-range sensor provided on the buffer 122 of the front portion 111 of the main body 110, a cliff sensor provided on the bottom of the main body 110, and sensing devices such as a magnetometer, accelerometer, gyroscope, and odometer provided inside the main body 110, and is used to provide the control module with various position information and motion state information of the equipment. The position determination device 121 includes a camera and a laser distance measuring device (LDS).

[0022] As shown in Figure 1, a shock absorber 122 is mounted on the front portion 111 of the main body 110. During the cleaning process, when the drive wheel module 141 moves the self-propelled cleaning machine 100 on the ground, the shock absorber 122 detects one or more events in the travel path of the self-propelled cleaning machine 100 through a sensor system mounted on it, such as an infrared sensor. The self-propelled cleaning machine 100 then controls the drive wheel module 141 in response to the event detected by the shock absorber 122, such as an obstacle or a wall, causing the self-propelled cleaning machine 100 to move away from the obstacle or otherwise respond to the event.

[0023] The control module is located on a circuit board within the main unit 110 and includes a computing processor, such as a central processing unit and an application processor, which communicate with non-temporary storage devices, such as hard disks, flash memory, and random access memory. The application processor uses a positioning algorithm, such as Simultaneous Localization and Mapping (SLAM), based on obstacle information fed back from the laser rangefinder, to create an immediate map of the environment in which the self-propelled cleaning device 100 is located. Furthermore, by combining distance information and speed information fed back from sensing devices such as sensors, cliff sensors, magnetometers, accelerometers, gyroscopes, and odometers installed on the buffer 122, the system comprehensively determines the working state of the self-propelled cleaning machine 100, its location, and its current position and orientation, such as crossing thresholds, climbing onto carpets, being on cliffs, getting stuck above or below, having a full dustbin, or being lifted. Based on these determinations, the system presents specific next action strategies according to different situations, thereby improving the cleaning performance and user experience of the self-propelled cleaning machine 100.

[0024] As shown in Figure 2, the drive system 140 operates the machine body 110 to travel on the ground based on drive commands that include distance and angle information, e.g., x, y, and θ components. The drive system 140 includes a drive wheel module 141, which can control the left and right wheels simultaneously. Preferably, to precisely control the motion of the machine, the drive wheel module 141 includes a left drive wheel module and a right drive wheel module. The left and right drive wheel modules are arranged along the lateral axis defined by the machine body 110. To enable the self-propelled cleaning machine 100 to move more stably on the ground and to exhibit higher mobility, the self-propelled cleaning machine 100 includes one or more driven wheels 142, which include, but are not limited to, omnidirectional wheels. The drive wheel module 141 includes driving wheels, a drive motor, and a control circuit that controls the drive motor. The drive wheel module 141 may further include a circuit for measuring the drive current and an odometer. The drive wheels have an offset drop suspension system, which is movable and fixed, for example, rotatably connected to the equipment body 110, and offset downward away from the equipment body 110 by an offset spring. The offset spring allows the drive wheels to maintain contact and traction with the ground with a constant grounding force, and at the same time, the cleaning element 183 of the self-propelled cleaning equipment 100 can also contact the ground with a constant pressure.

[0025] The energy system includes rechargeable batteries, such as nickel-metal hydride batteries or lithium batteries. The rechargeable batteries are connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery voltage under-monitoring circuit. These circuits are connected to a microcontroller control circuit. The main unit is connected to the base station 200 for charging via charging electrodes located on its side or bottom.

[0026] The man-machine interactive system 170 includes buttons on the main unit panel, which the user uses to select functions; a display and / or indicator lights and / or a speaker, which the display, indicator lights and speaker are used to show the user the current status of the device or function options; and further includes a smartphone application program. In the case of the route navigation type self-propelled cleaning device 100, the smartphone app can display to the user a map of the environment in which the device is located and the location of the device, providing the user with a richer and more user-friendly set of functions.

[0027] As shown in Figure 2, the cleaning system 150 includes a dry cleaning system 151, meaning the self-propelled cleaning machine 100 may be a sweeping vacuum cleaner, or the cleaning system 150 includes a wet cleaning system and a dry cleaning system 151, meaning the self-propelled cleaning machine 100 may be a sweeping and mopping vacuum cleaner. Here, the wet cleaning system includes at least one cleaning element 183, which may be a mop plate or other wet cleaning member.

[0028] As shown in Figure 2, the dry cleaning system 151 provided by an embodiment of the present disclosure includes a roller brush, a dust box, and a dust collection fan. The roller brush, having a certain interference with the ground, sweeps up debris from the ground and draws it into the dust collection port in front of the dust collection port between the roller brush and the dust box, where it is then sucked into the dust box by a gas with suction force generated by the dust collection fan and passing through the dust box. The dry cleaning system 151 also includes a side brush 152 having a rotating shaft, which is at a certain angle to the ground and is used to move debris to the roller brush area of ​​the cleaning system 150.

[0029] The dust box 160 provided in the embodiment of this disclosure is detachably connected to the main body 110 of the self-propelled cleaning machine 100, thereby allowing the dust box 160 to be removed from the main body 110 of the self-propelled cleaning machine 100 for cleaning or maintenance, and allowing the dust collection operation to be performed easily and quickly by attaching the dust box 160 to the main body 110, making it easy to operate and use.

[0030] As shown in Figures 3, 4, 5, and 6, the self-propelled cleaning machine 100 provided in the embodiment of the present disclosure has a dust box 160 equipped with a waste storage chamber 162, an air intake port 163 communicating with the waste storage chamber 162, and a dust discharge port 164. Here, the dust box 160 is further equipped with a dust inlet 166 communicating with the waste storage chamber 162 and an exhaust port 1601. The dust inlet 166 communicates with the dust intake port of the self-propelled cleaning machine 100 via a dust collection pipe, and the dust collection fan of the self-propelled cleaning machine 100 communicates with the exhaust port 1601 of the dust box 1601. A filter 161 is provided at the exhaust port 1601, and the airflow generated by the operation of the dust collection fan and having suction force removes dust from the surface to be cleaned. The dust is sucked into the dust box 160 via the dust intake port, dust intake conduit, and dust entry port 166, filtered by the filter section 161 at the exhaust port 1601, and then discharged from the exhaust port 1601 by the dust collection fan. As a result, the dust can be stored in the dust box 160, and by providing the filter section 161, the dust in the dust box 160 is sucked into the dust collection fan, thereby extending the lifespan of the dust collection fan.

[0031] Furthermore, as shown in Figure 3, a dust outlet 169 is provided in the main body 110 of the self-propelled cleaning machine 100, and a dust discharge passage 168 is provided inside the main body 110 to connect the dust discharge port 164 and the dust outlet 169. The base station 200 is provided with a dust collection port 2115 and a dust collection assembly 260 that communicates with the dust collection port 2115, and when the self-propelled cleaning machine 100 is parked at the base station 200, the dust outlet 169 of the self-propelled cleaning machine 100 is located at the base station 200. After docking with the dust collection port 2115 on the station 200, the dust collection assembly 260 on the base station 200 operates, and airflow flows in from the intake port 163 of the dust box 160, through the dust discharge port 164 and dust discharge passage 168, and into the base station 200 from the docked dust outlet 169 and dust collection port 2115, thereby collecting the debris in the dust box 160 into the base station 200 and enabling the dust collection operation.

[0032] Here, one-way valves are provided at both the intake port 163 and the dust outlet port 164 of the dust box 160. When cleaning the debris inside the dust box 160, that is, while the base station 200 is performing the dust collection operation of the self-propelled cleaning equipment 100, both the intake port 163 and the dust outlet port 164 of the dust box 160 are opened, allowing the airflow generated inside the dust box 160 to easily carry away the debris.

[0033] As shown in Figures 6 and 7, the base station 200 provided in this disclosure further includes a base station housing 210, the base station housing 210 being provided with a dust collection port 2115. Here, when the self-propelled cleaning machine 100 is docked at the base station 200, the dust outlet 169 of the self-propelled cleaning machine 100 is docked with the dust collection port 2115 on the base station 200 to perform dust collection operations. Specifically, the base station 200 is provided with a housing chamber 211, and when the self-propelled cleaning machine 100 is docked at the base station 200, at least a portion of the self-propelled cleaning machine 100 is housed in the housing chamber 211, the dust collection port 2115 is located inside the housing chamber 211, specifically the dust collection port 2115 is located on the side wall of the housing chamber 211.

[0034] As shown in Figure 8, the dust collection assembly 260 of the base station 200 includes a dust collection device 261, a dust bag bin 215 located within the base station housing 210, a noise reduction housing 262, a dust collection conduit 263, and a dust collection fan 264, where the dust collection device 261 is located within the dust bag bin 215, the noise reduction housing 262 has an air outlet 2621, the dust collection conduit 263 connects the dust outlet 2115, the dust bag bin 215, and the noise reduction housing 262 to form a dust collection air duct, and the dust collection fan 264 is located in the dust collection air duct. The dust collection airflow generated by the dust collection fan 264 sucks in debris from the dust box 160 of the self-propelled cleaning machine 100 through the dust outlet 2115, and after the debris is collected and blocked by the dust collection device 261, the dust collection airflow is discharged from the air outlet 2621. The airflow generated by the operation of the dust collection fan 264 is discharged from the air outlet 2621 on the noise reduction housing 262. The noise reduction housing 262 processes the airflow flowing inside to reduce noise, so the airflow in the dust collection duct is discharged after being noise-reduced by the noise reduction housing 262. This significantly reduces the aerodynamic noise of the dust collection fan 264, reduces the operating noise of the fan, and improves user comfort. Here, the dust collection device 261 may be a dust bag or other component that meets the requirements.

[0035] Specifically, as shown in Figure 8, the dust collection conduit 263 includes a first dust collection conduit 2631 and a second dust collection conduit 2632, the first dust collection conduit 2631 connecting the dust collection port 2115 and the dust bag bin 215, and the second dust collection conduit 2632 connecting the dust collection fan 264 and the noise reduction housing 262. When the dust outlet 169 of the self-propelled cleaning machine 100 is docked with the dust collection port 2115 of the base station 200, the dust collection airflow generated by the dust collection fan 264 flows from the dust box 160, dust discharge passage 168, dust outlet 169, and dust collection port 2115 of the self-propelled cleaning machine 100 through the first dust collection pipeline 2631 into the dust bag 216 in the dust bag bin 215. After the debris is collected and blocked by the dust collection device 261, the dust collection airflow flows from the dust bag bin 215 through the dust collection fan 264 and the second dust collection pipeline 2162 into the noise reduction housing 262. The air is then discharged into the base station housing 210 from the air outlet 2621 of the noise reduction housing 262. The noise reduction housing 262 processes the airflow flowing inside to reduce noise, achieving the objective of reducing the operating noise of the dust collection fan 264 and improving user comfort.

[0036] In some feasible embodiments provided by this disclosure, as shown in Figures 9 and 13, an air outlet 2119 is further opened in the base station housing 210, and the air outlet 2621 does not face the air outlet 2119. That is, the dust collection airflow is discharged from the air outlet 2621 of the noise reduction housing 262, flows into the base station housing 210, and is discharged to the outside environment through the air outlet 2119 opened in the base station housing 210. Since the air outlet 2621 does not face the air outlet 2119, the propagation path of the dust-collecting airflow between the air outlet 2621 and the air outlet 2119 becomes a winding path. This means that the operating noise of the dust-collecting fan 264 is discharged from the air outlet via the winding propagation path between the air outlet 2621 and the air outlet 2119. The winding propagation path blocks the propagation of sound to the outside and enhances the friction and dissipation of sound waves. As a result, the dust-collecting airflow achieves noise reduction again in the process of being discharged into the external environment via the air outlet 2621 and the air outlet 2119, reducing the impact of noise on the user and ultimately improving user comfort.

[0037] As shown in Figures 10 and 11, in some feasible embodiments provided by this disclosure, the dust bag bin 215 is provided with an air inlet 2151 and an air outlet 2152, a dust collector 261 is in communication with the air inlet 2151, the air inlet end of a dust collection fan 264 is connected to the air outlet 2152, and the air outlet end of the dust collection fan 264 is connected to a noise reduction housing 262 via a second dust collection conduit 2632. That is, the dust collection fan 264 is located between the dust bag bin 215 and the noise reduction housing 262 and is in communication with the noise reduction housing 262 via the second dust collection conduit 2632. As shown in Figure 8, the air inlet 2151 of the dust bag bin 215 is connected to the dust collection port 2115 of the base station via the first dust collection pipeline 2631. As shown in Figure 5, the dust box 160 of the self-propelled cleaning machine 100 is further provided with an air intake port 163 and a dust entry port 166. Here, as shown in Figure 3, after the dust outlet 169 of the self-propelled cleaning machine 100 is docked with the dust collection port 2115 of the base station 200, the dust collection fan 264 operates to generate a dust collection airflow, causing the dust in the dust box 160 of the self-propelled cleaning machine 100 to flow with the dust collection airflow and through the dust outlet 169 of the self-propelled cleaning machine 100, the dust collection port 2115 on the base station 200, the first dust collection pipeline 2631, and the air inlet 2151 of the dust bag bin 215 to flow into the dust collection device 261. After the dust is collected and blocked by the dust collection device 261, the dust collection airflow flows from the air outlet 2152 of the dust bag bin 215 into the dust collection fan 264, and then flows from the air outlet end of the dust collection fan 264 through the second dust collection pipeline 2632 into the noise reduction housing 262, is discharged into the base station housing 210 from the air outlet 2621 of the noise reduction housing 262, and is discharged into the external environment from the air outlet 2119 on the base station housing 219, thus achieving overall circulation.

[0038] Here, as shown in Figures 10, 11, and 12, the opening of the dust bag bin 215 on the base station housing 210 faces forward, and the front of the base station 200 is shown in Figure 6. As shown in Figures 6, 7, and 13, the base station 200 further includes a dust bag bin cover 2156, the dust bag bin cover 2156 and the base station housing 210 are detachably connected via a locking assembly that opens or closes the opening of the dust bag bin 215. When the dust bag bin cover 2156 closes the opening of the dust bag bin 215, it can also seal the opening of the dust bag bin 215, creating a sealed chamber in the dust collection duct and generating negative pressure, ensuring reliable operation of the dust collection operation. When the dust bag bin cover 2156 opens the opening of the dust bag bin 215, it facilitates the replacement of the dust collection device 261 inside the dust bag bin 215. Here, as shown in Figures 10 and 11, the base station 200 further includes a dust bag supporter 270 provided inside the dust bag bin 215, and the dust collection device 261 is mounted inside the dust bag bin 215 via the dust bag supporter 270.

[0039] In this embodiment, the dust bag bin cover 2156 is detachably connected to the base station housing 210 via a locking assembly. The locking assembly has a simple structure and low cost, which simplifies the structure of the base station 200 and reduces the manufacturing cost of the base station 200 compared to a system in related technology in which a pull-out drawer is placed on the base station to store the dust bag. At the same time, it has the advantage of being lower cost compared to a system in related technology in which the dust bag bin cover and the base station housing are connected by a magnetic attraction assembly. As shown in Figures 12 and 14, in some feasible embodiments provided by the Disclosure, a locking assembly connecting the dust bag bin cover 2156 to the base station housing 210 includes a first locking member 2157 and a second locking member 2158 that fit together, the first locking member 2157 located on the dust bag bin cover 2156 and the second locking member 2158 located on the base station housing 210, thereby allowing the dust bag bin cover 2156 to be connected to the base station housing 210 to block the opening of the dust bag bin 215, or the dust bag bin cover 2156 to be removed from the base station housing 210.

[0040] Here, the first locking member 2157 is detachably connected to the dust bag bin cover 2156, and maintenance costs can be reduced by removing and separating the first locking member 2157 and the dust bag bin cover 2156 for individual maintenance. In other embodiments, the positions of the first locking member 2157 and the second locking member 2158 are interchangeable. For example, the first locking member may be located on the base station body and the second locking member on the dust bag bin cover. In this disclosure, the case in which the first locking member 2157 is located on the dust bag bin cover 2156 and the second locking member 2158 is located on the base station housing 210 will be described as an example.

[0041] Furthermore, during the process of attaching and detaching the dust bag bin cover 2156 and the base station housing 210, the first locking member 2157 and the second locking member 2158 come into contact and wear occurs. Therefore, by making the first locking member 2157 detachably connected to the dust bag bin cover 2156, it becomes possible to replace the first locking member 2157 if it is significantly worn or damaged, making operation easier and reducing maintenance costs compared to related technologies where the first locking member and the dust bag bin cover are integrally molded, requiring the entire dust bag bin cover to be replaced if the first locking member is significantly worn or damaged.

[0042] As shown in Figure 12, in one specific example, the second locking member 2158 and the base station housing 210 are integrated into a single structure. This simplifies the assembly operation of the second locking member 2158 and the base station housing 210, which is advantageous for improving assembly efficiency. At the same time, it improves the connection reliability between the second locking member 2158 and the base station housing 210, and consequently improves the overall reliability of the base station 200. Under equivalent conditions, the wear rate of the second locking member 2158 may be lower than that of the first locking member 2157. In other words, by integrating the second locking member 2158, which has a lower wear rate, onto the base station housing 210, and detachably connecting the first locking member 2157, which has a higher wear rate, to the dust bag bin cover 2156, the replacement of the first locking member 2157 becomes easier, and the service life of the locking assembly can be extended.

[0043] In another specific example (not shown), the second locking member is detachably connected to the base station housing 210, which allows the second locking member and the base station housing 210 to be removed and separated for individual maintenance or replacement, thus reducing maintenance costs.

[0044] As shown in Figures 13 and 14, in some feasible embodiments provided by the present disclosure, the dust bag bin cover 2156 has a U-shaped structure and includes a front plate 21561 and side plates 21562 on both sides of the front plate 21561, with a first locking member 2157 located on the side plates 21562, and the base station housing 210 has two bag chamber side walls 21551 located on both sides of the opening of the dust bag bin 215 along a first direction, the first direction being the left-right direction of the base station 200, and as shown by arrow X in Figure 7, a second locking member 2158 is located on the bag chamber side wall 21551 and outside the dust bag bin 215. As a result, the dust bag bin cover 2156 snaps onto the outside of the two bag chamber side walls 21551 of the base station housing 210, and the first locking member 2157 and the second locking member 2158 lock together, so that the front plate 21561 blocks and seals the opening of the dust bag bin 215, resulting in a simple structure that can meet the compact structure and miniaturization design requirements of the base station 200, and such a structure is low cost.

[0045] As shown in Figures 15 and 16, in some feasible embodiments provided by the Disclosure, the first locking member 2157 includes a connected first connecting portion 21571 and a locking portion 21572, the first connecting portion 21571 being connected to a side plate 21562, thereby allowing the entire first locking member 2157 to be attached to the dust bag bin cover 2156. Here, the first connecting portion 21571 and the side plate 21562 are screw-connected, for example, by providing a through hole in the first connecting portion 21571 and a screw hole in the side plate 21562, and the screw being connected through the through hole to the screw hole on the side plate 21562, thereby fixing the first connecting portion 21571 to the dust bag bin cover 2156.

[0046] Here, as shown in Figure 12, the second locking member 2158 is a locking groove opened in the bag chamber side wall 21551, and the locking portion 21572 can be accommodated in or released from the locking groove. When the locking portion 21572 is accommodated in the locking groove, it connects the dust bag bin cover 2156 and the base station housing 210, blocking and sealing the opening of the dust bag bin 215. When the locking portion 21572 is released from the locking groove, it separates the dust bag bin cover 2156 and the base station housing 210, opening the opening of the dust bag bin 2155 and facilitating the replacement of the dust collection device 261.

[0047] Here, at least the locking portion 21572 of the first locking member 2157 is configured as an elastic member, and by configuring the locking portion 21572 as an elastic member, the locking portion 21572 can be smoothly and reliably accommodated in and out of the locking groove, thereby ensuring smooth locking or separation of the first locking member 2157 and the second locking member 2158. Furthermore, the first connecting portion 21571 of the first locking member 2157 is configured as an elastic member, and for example, the entire first locking member 2157 is configured as an elastic member, which facilitates processing.

[0048] As shown in Figure 14, in the above embodiment, the dust bag bin cover 2156 includes a bin cover body 21567 and a decorative cover 21568 located outside the bin cover body 21567. The first locking member 2157 is located between the bin cover body 21567 and the decorative cover 21568 and is connected to the bin cover body 21567. That is, the first connecting portion 21571 of the first locking member 2157 is connected to the bin cover body 21567, and the decorative cover 21568 can block the first locking member 2157, thereby ensuring the aesthetic appearance of the dust bag bin cover 2156.

[0049] A retraction hole 21563 is provided in the bin cover body 21567 at a position opposite to the locking portion 21572. The retraction hole 21563 exposes at least a portion of the locking portion 21572 to the inside of the dust bag bin cover 2156. The dust bag bin cover 2156 is then locked to the second locking member 2158 outside the two bag bin side plates 21562 of the base station 200, connecting the dust bag bin cover 2156 to the base station housing 210 and sealing the dust bag bin 215. At the same time, in this arrangement, the decorative cover 21568 at the position opposite to the retraction hole 21563 acts to block and restrict the locking portion 21572, thereby further improving the reliability and stability of the locking portion 21572's accommodation within the locking groove and improving the locking reliability between the dust bag bin cover 2156 and the base station housing 210.

[0050] Here, the decorative cover 21568 is detachably connected to the bottle cover body 21567 by at least one of a screw structure, a locking structure, a mortise joint structure, or a heat-welding adhesive, making it easy to remove the decorative cover 21568 and the bottle cover body 21567 and replace the first locking member 2157.

[0051] As shown in Figures 14 and 15, in some feasible embodiments provided in this disclosure, a positioning portion 21565 is provided on the side of the bin cover body 21567 away from the decorative cover 21568, and a limiting portion 21552 is further provided on the base station housing 210, and the limiting portion 2155 The positioning portion 21565 is fitted to the dust bag bin cover 2156, and is used to restrict the movement of the dust bag bin cover 2156 relative to the base station housing 210. This allows the positioning portion 21565 and the limiting portion 21552 to pre-position the assembly of the dust bag bin cover 2156 and the base station housing 210, improve the locking accuracy of the first locking member 2157 and the second locking member 2158, and improve the assembly efficiency of the dust bag bin cover 2156 and the base station housing 210. Here, the positioning portion 21565 and the limiting portion 21552 may be a groove and projection that fit together with each other, for example, the positioning portion 21565 is a positioning projection provided on the bin cover body 21567, and the limiting portion 21552 is a limiting groove provided on the bag chamber side wall 21551 of the base station housing 210.

[0052] In some feasible embodiments provided in this disclosure, a sealing structure is provided on the side of the bin cover body 21567 away from the decorative cover 21568 to seal the gap between the bin cover body 21567 and the base station housing 210 when the dust bag bin cover 2156 closes the opening of the dust bag bin 215. The installation of the sealing structure improves the sealing of the connection between the dust bag bin cover 2156 and the base station housing 210, thereby creating a sealed chamber for the dust bag bin 215 and ensuring the reliability of the dust collection operation. Specifically, the sealing structure may be a sealing ring, a sealing surface, or other sealing structure, but is not limited thereto. The sealing structure is attached to the bin cover body 21567 using at least one of an adhesive, a locking structure, a mortise and tenon structure, or a screw structure.

[0053] As shown in Figures 15 and 16, in some feasible embodiments provided by this disclosure, the number of locking portions 21572 is one or at least two, and the number of locking portions 21572 can be reasonably determined depending on the specific structure and dimensions of the locking portions 21572 to ensure the reliability and stability of the locking of the first locking member 2157 and the second locking member 2158. Here, at least two locking portions 21572 are distributed at intervals so that even if one locking portion 21572 is damaged and deformed, the locking of the non-deformable locking portion 21572 with the second locking member 2158 still ensures the reliability of the connection between the first locking member 2157 and the second locking member 2158, and thus extends the service life of the first locking member 2157.

[0054] As shown in Figures 15 and 16, in the above embodiment, the retraction holes 21563 correspond one-to-one with the locking portions 21572, and the bin cover body 21567 is provided with a partition rib 21564 between two adjacent retraction holes 21563. The installation of the partition rib 21564 effectively protects the two adjacent locking portions 21572, reduces the impact of a deformed locking portion 21572 on the adjacent locking portion 21572, is advantageous in extending the service life of the entire first locking member 2157, and consequently improves the reliability of the first locking member 2157.

[0055] In one specific example, the locking groove corresponds one-to-one with the locking portion 21572, which is advantageous in improving the locking reliability of the first locking portion 21572 and the second locking portion 21572, and consequently, the locking reliability of the dust bag bin cover 2156 and the base station housing 210 can be improved.

[0056] As shown in Figure 12, in another specific example, all locking parts 21572 correspond to a single locking groove, which simplifies the machining of the locking groove and is advantageous in reducing the manufacturing cost of the base station housing 210.

[0057] As shown in Figure 10, in the above embodiment, a first filter member 2153 is provided inside the dust bag bin 215, and the first filter member 2153 is located at the air outlet 2152. By installing the first filter member 2153, the dust collection airflow that flows into the dust collection fan 264 from the air outlet 2152 of the dust bag bin 215 can be filtered, thereby improving the cleaning performance of the airflow that flows into the dust collection fan 264, which is advantageous in extending the service life of the dust collection fan 264 and improving the reliability of the dust collection assembly 260.

[0058] Specifically, the first filtration member 2153 may be a filter rope, filter cotton, or other filtration member, and the first filtration member 2153 is fixed to the outlet 2152 of the dust bag bin 215 by at least one of a locking structure, a mortise and tenon joint structure, an adhesive, or a screw structure.

[0059] Typically, to improve space utilization and dust bag capacity, dust bags are often designed and manufactured to be the same size as, or slightly smaller than, the dust bag bin. However, during dust collection, the suction force of the dust collection fan can cause the bottom of the dust bag to adhere to the air outlet of the dust bag bin, potentially leading to clogging. Over long periods of use, the gravity of the dust and the suction force of the dust collection fan can cause even dust bags that were not initially in contact with the air outlet to stretch, potentially covering the air outlet and causing clogging. Therefore, as shown in Figure 10, in some feasible embodiments provided by this disclosure, a plurality of support parts 2154 are provided within the dust bag bin 215, distributed at intervals around the air outlet 2152, supporting at least some of the dust collection devices 261. The installation of the support parts 2154 prevents the dust collection devices 261 from completely covering the air outlet 2152, promoting the flow of the dust collection airflow, preventing clogging, and contributing to improved dust collection efficiency.

[0060] As shown in Figure 2, the self-propelled cleaning machine provided in this disclosure includes a cleaning assembly, a water supply mechanism, a liquid storage tank, etc. The cleaning assembly is located below the liquid storage tank, and the cleaning liquid inside the liquid storage tank is transported to the cleaning assembly via the water supply mechanism, thereby allowing the cleaning assembly to wet-clean the surface to be cleaned. In other embodiments of this disclosure, the cleaning liquid inside the liquid storage tank is sprayed directly onto the surface to be cleaned, and the cleaning assembly uniformly applies the cleaning liquid to achieve cleaning of the surface. The self-propelled cleaning machine 100 is also provided with a water inlet that communicates with the liquid storage tank, and the water inlet can be used to replenish the liquid storage tank with liquid from outside the self-propelled cleaning machine 100, thereby enabling the liquid storage tank to be refilled.

[0061] The cleaning assembly provided in the embodiments of this disclosure includes a motion mechanism and a cleaning element 183 mounted on a device body 110, i.e., the entire cleaning assembly is mounted on the device body 110 via the motion mechanism, and the cleaning assembly moves with the movement of the device body 110 to perform a mopping function. Here, the motion mechanism is used to drive the movement of the cleaning element 183, for example, the motion mechanism can drive the lifting and lowering of the cleaning element 183, or the motion mechanism can drive the rotation of the cleaning element 183, and thus, depending on whether the cleaning element 183 needs to come into contact with the surface to be cleaned, the lifting and lowering and rotational operations of the cleaning element 183 can be realized through the motion mechanism, and different functional requirements of the cleaning element 183 can be met, i.e., the segmentation strategy of the cleaning element 183 can be handled, improving the cleaning performance of the self-cleaning device and improving cleaning efficiency and user experience.

[0062] Here, as shown in Figure 2, in the forward direction of the self-propelled cleaning machine 100, the cleaning element 183 is located at the rear of the dry cleaning system 151, and the cleaning element 183 is usually a flexible material with water absorption, such as cloth or sponge. In this solution, the cleaning element 183 is at least one turntable, which guides water from the liquid storage tank of the self-propelled robot to the cleaning element 183, and the wet cleaning element 183 removes dirt from the ground by rotational motion.

[0063] Although this disclosure has been described through the above-described embodiments, these embodiments are for illustrative and explanatory purposes only and do not limit this disclosure to the scope of the embodiments described. Furthermore, those skilled in the art will understand that this disclosure is not limited to the above-described embodiments and that many more variations and modifications are possible based on the teachings of this disclosure, all of which fall within the scope of protection of this disclosure. The scope of protection of this disclosure shall be defined by the appended claims and their equivalent scope.
