[0022] 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.

[0023] 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.

[0024] 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.

[0025] As shown in Figures 1 to 24, embodiments of the present disclosure provide a base station 200 and a cleaning robot system comprising 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.

[0026] 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. The self-propelled cleaning machine 100 may also 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, if necessary, stops the cleaning task, it returns to the base station 200 for operations such as charging, and / or rehydrating, and / or washing, and / or dust collection.

[0027] 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.

[0028] 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 sensor (LDS).

[0029] 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.

[0030] The control module is provided on a circuit board within the main unit 110 of the device and includes a computing processor, such as a central processing unit and an application processor, which communicates with non-temporary storage devices, such as a hard disk, 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 whether it has crossed a threshold, climbed onto a carpet, is on a cliff, is stuck above or below, its dustbin is full, or has been 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.

[0031] 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, and to precisely control the motion of the machine, the drive wheel module 141 optionally 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 running wheels, a drive motor, and a control circuit that controls the drive motor, and 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] As shown in Figure 3, the main body 110 of the self-propelled cleaning machine 100 is further provided with a dust outlet 169, and a dust discharge passage 168 for connecting a dust discharge port 164 and a dust outlet 169 is further provided inside the main body 110, and the base station 200 is provided with a dust collection port 2115 and a dust collection assembly 260 communicating 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 connected to the base 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.

[0038] 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 out the debris. The specific structure of the dust box 160 will be described in detail later.

[0039] As shown in Figures 7 and 8, the base station 200 provided in this disclosure includes a base station housing 210 and a dust collection assembly 260, 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.

[0040] As shown in Figures 9, 10, and 13, the dust collection assembly 260 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 is provided with an air outlet 2621, and the dust collection conduit 263 is provided with a dust collection port 2115, and a dust bag bin 215. The fan 215 communicates with the noise reduction housing 262 to form a dust collection air passage. The dust collection fan 264 is installed in the dust collection air passage to generate a dust collection airflow. The dust collection airflow generated by the dust collection fan 264 draws dust from the dust box 160 of the self-propelled cleaning machine 100 through the dust collection port 2115 to the dust bag collection device 261. The dust is collected and sealed by the dust collection device 261 and then contained within it. The dust collection airflow is then discharged from the air outlet 2621. The dust collection 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 dust collection airflow flowing inside to reduce noise. Therefore, the dust collection airflow in the dust collection air passage is discharged after noise reduction by the noise reduction housing 262, which significantly reduces the aerodynamic noise of the dust collection fan 264, reduces the fan's operating noise, and improves user comfort. Here, the dust collection device 261 may be a dust bag or other component that meets the requirements.

[0041] Specifically, as shown in Figure 9, the dust collection pipeline 263 includes a first dust collection pipeline 2631 and a second dust collection pipeline 2632, the first dust collection pipeline 2631 connecting the dust collection port 2115 and the dust bag bin 215, and the second dust collection pipeline 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, as shown in Figures 3, 9, and 13, and the dust collection airflow collects the debris in the dust box 160 from the dust collection device 261 After the dust is drawn in and 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, and is 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.

[0042] In some feasible embodiments provided by this disclosure, a first sound-absorbing member is provided within the noise reduction housing 262, and the first sound-absorbing member may be made of sound-absorbing cotton or other sound-absorbing material. By providing the first sound-absorbing member within the noise reduction housing 262, the dust collection airflow flowing within the noise reduction housing 262 can be subjected to noise reduction treatment, thereby further improving the noise reduction effect of the noise reduction housing 262.

[0043] Furthermore, in the dust collection assembly 260 provided in this disclosure, by adding a noise reduction housing 262 to the end of the dust collection air passage, the dust collection airflow is not directly discharged by the dust collection fan as in embodiments of related technologies, but is discharged from the noise reduction housing 262 connected to the dust collection fan 264. As a result, the dust collection airflow continues to flow within the noise reduction housing 262 before being discharged, thereby achieving the noise reduction objective with the first sound-absorbing member provided within the noise reduction housing 262, further ensuring a good noise reduction effect, and reducing the operating noise of the dust collection fan 264.

[0044] In some feasible embodiments provided by this disclosure, as shown in Figures 12 and 19, the base station housing 210 is further provided with an air outlet 2119, 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 from the air outlet 2119 provided in the base station housing 210. Since the air outlet 2621 does not face the air outlet 2119, the propagation path of the dust collection airflow between the air outlet 2621 and the air outlet 2119 becomes a winding path. This means that the operating noise of the dust collection 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 collection 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, which is advantageous in reducing the impact of noise on the user and ultimately improving user comfort.

[0045] In the above embodiment, as shown in Figure 12, the base station housing 210 includes four main body side walls that are sequentially connected to form a frame structure. Furthermore, the housing chamber 211 for housing the self-propelled cleaning equipment 100 in the base station 200 is located on one of the main body side walls at the front of the base station 200, which is shown in Figure 7. Here, the air outlet 2621 faces one of the main body side walls, and the air outlet 2119 is provided on the other main body side wall. As a result, the propagation path for the dust collection airflow between the air outlet 2621 and the air outlet 2119 becomes a winding path, ensuring a good noise reduction effect.

[0046] Here, the air outlet 2119 may be provided on one, two, or three of the other three main body side walls, excluding the main body side wall facing the air outlet 2621. In some embodiments, the air outlet 2119 may be provided on the main body side wall facing the air outlet 2621, and the air outlet 2119 may not face the air outlet 2621; for example, the air outlet 2119 may be provided at a distance from the air outlet 2621.

[0047] As shown in Figure 11, in some feasible embodiments provided by this disclosure, a second sound-absorbing member 2641 is provided on the dust collection fan 264, and the second sound-absorbing member 2641 is used to absorb sound from the dust collection airflow at the air outlet of the dust collection fan 264, thereby further reducing the aerodynamic noise of the dust collection fan 264, reducing the operating noise of the dust collection fan 264, and improving user comfort.

[0048] Furthermore, the second sound-absorbing member 2641 is configured to filter the dust-collecting airflow at the air outlet of the dust collection fan 264. For example, if the second sound-absorbing member 2641 is sound-absorbing filter cotton, the second sound-absorbing member 2641 also has a simultaneous filtering effect. That is, the second sound-absorbing member 2641 simultaneously exhibits noise reduction and re-filtration of the dust-collecting airflow. This significantly reduces the operating noise of the dust collection fan 264, and by filtering the dust-collecting airflow that flows out from the air outlet of the dust collection fan 264, the cleanliness of the airflow discharged into the external environment can be improved.

[0049] Furthermore, impurities such as carbon powder are generated during the operation of the dust collection fan 264, and these impurities can also be filtered by the second sound-absorbing member 2641. In other words, the second sound-absorbing member 2641 not only filters the dust collection airflow from the dust box 160, but also filters out impurities such as carbon powder generated by the operation of the dust collection fan 264, further improving the cleanliness of the airflow discharged into the external environment and reducing environmental pollution.

[0050] As shown in Figures 10 and 11, in the above embodiment, the dust collection fan 264 is a vortex fan. Here, because the vortex fan has a small volume, high pressure and a comfortable airflow velocity, it can meet the miniaturization design requirements of the base station 200 while ensuring high dust collection efficiency and a good dust collection effect.

[0051] Here, the vortex fan is provided with a vortex chamber 2642 and a transition chamber 2643 that communicate with each other via an air vent 2644. An air inlet is provided in the chamber wall of the vortex chamber 2642, and an air outlet is provided in the chamber wall of the transition chamber 2643. The second sound-absorbing member 2641 is located inside the vortex chamber 2642. As a result, as shown in Figure 11, the second sound-absorbing member 2641 can absorb and filter the dust-collecting airflow flowing from the vortex chamber 2642 into the transition chamber 2643.

[0052] As shown in Figures 9, 13, and 14, 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, the dust collection device 261 communicates with the air inlet 2151, the air inlet of the dust collection fan 264 is connected to the air outlet 2152, and the air outlet of the dust collection fan 264 is connected to the noise reduction housing 262 via a second dust collection air inlet conduit 2632. That is, the dust collection fan 264 is located between the dust bag bin 215 and the noise reduction housing 262 and communicates with the noise reduction housing 262 via the second dust collection conduit 2632. Furthermore, the air inlet 2151 of the dust bag bin 215 communicates with the dust collection port 2115 of the base station via the first dust collection conduit 2631, and 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, 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 works to generate a dust collection airflow, thereby causing the dust in the dust box 160 of the self-propelled cleaning machine 100 to flow with the dust collection airflow and flow 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 airflow inlet 2151 of the dust bag bin 215 to the dust collection device 261, and the dust flows into the dust collection device 261. After being 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 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, thereby achieving overall circulation.

[0053] Here, a sealing section is further provided around the dust collection port 2115 of the base station 200. After the dust outlet 169 of the self-propelled cleaning device 100 is docked with the dust collection port 2115, the installation of the sealing section seals the gap between the dust outlet 169 and the dust collection port 2115. This avoids the problem of inability to collect dust due to airflow leakage between the dust outlet 169 and the dust collection port 2115, which prevents the formation of negative pressure in the dust collection airflow path. At the same time, it prevents dust from leaking to the outside due to airflow leakage between the dust outlet 169 and the dust collection port 2115, ensuring smooth execution of the dust collection operation and ensuring a good dust collection effect. Specifically, the sealing section may be made of an elastic material.

[0054] As shown in Figure 8, a decorative opening 21151 is further provided within the housing chamber 211 of the base station 200. For example, the decorative opening 21151 is provided on the side wall of the housing chamber 211, and the decorative opening 21151 and the dust collection opening 2115 are positioned on both sides of the center line parallel to the vertical direction of the base station 200. For example, the decorative opening 21151 and the dust collection opening 2115 are positioned on both the left and right sides of the housing chamber 211, and an elastic part is also provided around the decorative opening 21151, thereby allowing the self-propelled cleaning machine 100 to move to the base station When docking at station 200, after the dust outlet 169 is docked with the dust collection port 2115, the rest of the self-propelled cleaning machine 100 comes into contact with the elastic part around the decorative port 21151, ensuring that the self-propelled cleaning machine 100 is securely docked at base station 200 and reducing the possibility of the self-propelled cleaning machine 100 swaying during the dust collection process. At the same time, the installation of the decorative port 21151 ensures a clean and aesthetically pleasing appearance of base station 200.

[0055] As shown in Figure 13, 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.

[0056] 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 an engagement structure, a mortise and tenon joint structure, an adhesive, or a screw structure.

[0057] Typically, in order to improve space utilization and dust bag capacity, the dimensions of the dust bag are often set to be the same as or slightly smaller than the dimensions of the dust bag bin during design and production. However, during dust collection, the suction force of the dust collection fan can draw the bottom of the dust bag into the air outlet of the dust bag bin, potentially causing clogging. During prolonged use, due to the effects of dust gravity and the suction force of the dust collection fan, even dust bags that do not normally come into contact with the air outlet can stretch, and their bottoms can cover the air outlet, potentially causing clogging. Therefore, as shown in Figure 13, in some feasible embodiments provided by this disclosure, a plurality of support parts 2154 are provided within the dust bag bin 215, and the plurality of support parts 2154 are arranged at intervals in the air outlet 2152 and configured to support 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, which is advantageous for the flow of the dust collection airflow, prevents clogging, and is advantageous for improving dust collection efficiency.

[0058] As shown in Figures 7, 8, 13, 14, 19, and 20, in some feasible embodiments provided by this disclosure, the base station 200 further includes a dust bag bin cover 2156, and the opening of the dust bag bin 215 on the base station housing 210 faces forward, where the front-to-back direction of the base station 200 is shown in Figure 7, i.e., the opening of the dust bag bin 215 is located at the front of the base station 200. The dust bag bin cover 2156 is detachably connected to the base station housing 210 to block or open the opening of the dust bag bin 215, and when the dust bag bin cover 2156 blocks the opening of the dust bag bin 215, the opening of the dust bag bin 215 is also sealed, thereby creating a sealed chamber in the dust bag bin 215 that generates negative pressure in the dust collection air passage, ensuring reliable execution of the dust collection operation.

[0059] In this embodiment, the dust bag bin cover 2156 allows for easy opening and closing of the dust bag bin 215. For example, the dust bag bin cover 2156 can be removed from the base station housing 210 to expose the opening of the dust bag bin 215, allowing the user to easily remove or replace the dust collection device 261 through the opening of the dust bag bin 215, making it easy to use. When a dust collection operation needs to be performed, the dust bag bin cover 2156 is engaged with the opening of the dust bag bin 215 to seal the dust bag bin 215, so that the dust bag bin 215 forms part of the dust collection airflow path.

[0060] Here, the dust bag bin cover 2156 is detachably connected to the base station housing 210 via at least one of the following: an engaging structure, a mortise joint structure, a magnetic attraction structure, and a screw structure.

[0061] In the above embodiment, the dust bag bin cover 2156 is removably connected to the base station housing 210 via an engagement assembly. Because the engagement assembly has a simple structure and low cost, it simplifies the structure of the base station 200 and reduces the manufacturing cost of the base station 200 compared to the method in related technologies in which a pull-out drawer is placed in the base station to store the dust bag. At the same time, it has the advantage of being similarly low-cost compared to the method in related technologies in which the dust bag bin cover and the base station housing are connected via a magnetic attraction assembly.

[0062] As shown in Figures 18 and 20, in some feasible embodiments provided by the Disclosure, an engagement assembly connecting a dust bag bin cover 2156 to a base station housing 210 includes a first engagement member 2157 and a second engagement member 2158 that match each other, the first engagement member 2157 located on the dust bag bin cover 2156 and the second engagement member 2158 located on the base station housing 210, thereby enabling the mutual engagement of the first engagement member 2157 and the second engagement member 2158 to connect the dust bag bin cover 2156 to the base station housing 210 to seal the opening of the dust bag bin 215, or to detach the dust bag bin cover 2156 from the base station housing 210.

[0063] Here, the first engaging member 2157 is detachably connected to the dust bag bin cover 2156, allowing the first engaging member 2157 and the dust bag bin cover 2156 to be removed, separated, and maintained individually, which is advantageous in reducing maintenance costs. In other embodiments, the first engaging member 2157 and the second engaging member 2158 are interchangeable. For example, the first engaging member may be located in the base station housing 210 and the second engaging member in the dust bag bin cover. In this disclosure, the case in which the first engaging member 2157 is located in the dust bag bin cover 2156 and the second engaging member 2158 is located in the base station housing 210 will be described as an example.

[0064] Furthermore, during the process of attaching and detaching the dust bag bin cover 2156 and the base station housing 210, the first engaging member 2157 comes into contact with the second engaging member 2158 and wears down. The detachable connection between the first engaging member 2157 and the dust bag bin cover 2156 allows for the replacement of the first engaging member 2157 if it is significantly worn or damaged, making the operation easy and reducing maintenance costs compared to related technologies where the first engaging member and the dust bag bin cover are integrally molded, requiring the replacement of the entire dust bag bin cover when the first engaging member is significantly worn or damaged.

[0065] As shown in Figures 13 and 18, in one specific example, the second engaging member 2158 and the base station housing 210 are integrated into a single structure, which simplifies the assembly operation of the second engaging member 2158 and the base station housing 210, is advantageous for improving assembly efficiency, and at the same time improves the connection reliability between the second engaging member 2158 and the base station housing 210, and further improves the overall reliability of the base station 200. Furthermore, under equivalent conditions, the wear rate of the second engaging member 2158 may be lower than that of the first engaging member 2157. That is, by integrating the second engaging member 2158, which has a lower wear rate, into the base station housing 210, and detachably connecting the first engaging member 2157, which has a higher wear rate, to the dust bag bin cover 2156, the replacement of the first engaging member 2157 becomes easier, and the service life of the engaging assembly can be extended.

[0066] In another specific example (not shown), the second engaging member is detachably connected to the base station housing 210, which allows the second engaging member to be removed from the base station housing 210, separated, and then individually maintained or replaced, which is advantageous in reducing maintenance costs.

[0067] As shown in Figures 19 and 20, in some feasible embodiments provided by the 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 engaging member 2157 located on the side plates 21562, and the base station housing 210 includes 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 8, a second engaging member 2158 is located on the bag chamber side wall 21551 and is located outside the dust bag bin 215. As a result, the dust bag bin cover 2156 engages with the outside of the two bag chamber side walls 21551 of the base station housing 210, and the first engaging member 2157 engages with the second engaging member 2158, so that the front plate 21561 can block and seal the opening of the dust bag bin 215, the structure is simple, it can meet the design requirements of a compact and miniaturized base station 200, and such a structure is inexpensive.

[0068] As shown in Figures 21 and 22, in some feasible embodiments provided by this disclosure, the first engaging member 2157 includes a connected first connecting portion 21571 and an engaging portion 21572, the first connecting portion 21571 being connected to a side plate 21562, and the connection between the first connecting portion 21571 and the side plate 21562 allows the entire first engaging 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, the first connecting portion 21571 is provided with a through hole and the side plate 21562 is provided with a screw hole, and the screw passes through the through hole and is connected to the screw hole on the side plate 21562, thereby fixing the first connecting portion 21571 to the dust bag bin cover 21566.

[0069] Here, as shown in Figures 13 and 18, the second engaging member 2158 is an engaging groove provided in the bag chamber side wall 21551, and the engaging portion 21572 can be housed in or disengaged from the engaging groove. When the engaging portion 21572 is housed in the engaging 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 engaging portion 21572 is disengaged from the engaging groove, it separates the dust bag bin cover 2156 and the base station housing 210, opening the opening of the dust bag bin 215 and facilitating the replacement of the dust collection device 261.

[0070] Here, at least the engaging portion 21572 of the first engaging member 2157 is configured as an elastic member. By configuring the engaging portion 21572 as an elastic member, the engaging portion 21572 can be smoothly and reliably accommodated in and disengaged from the engaging groove, ensuring smooth engagement or disengagement of the first engaging member 2157 and the second engaging member 2158. The first connecting portion 21571 of the first engaging member 2157 may also be configured as an elastic member, or for example, the entire first engaging member 2157 may be configured as an elastic member, which facilitates processing.

[0071] As shown in Figure 20, 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 engaging 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 engaging member 2157 is connected to the bin cover body 21567, and the decorative cover 21568 can block the first engaging member 2157, thereby ensuring the aesthetic appearance of the dust bag bin cover 2156.

[0072] A retraction hole 21563 is provided in the bin cover body 21567 at a position opposite to the engaging portion 21572. The retraction hole 21563 exposes at least a portion of the engaging portion 21572 to the inside of the dust bag bin cover 2156. The dust bag bin cover 2156 engages with the second engaging 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 engaging portion 21572, thereby further improving the reliability and stability of the engagement of the engaging portion 21572 within the engagement groove, and improving the engagement reliability between the dust bag bin cover 2156 and the base station housing 210.

[0073] Here, the decorative cover 21568 is detachably connected to the bottle cover body 21567 by at least one of a screw structure, an engagement 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 engagement member 2157.

[0074] As shown in Figures 18 and 20, in some feasible embodiments provided by 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 21552 and the positioning portion 21565 are used in cooperation to restrict the movement of the dust bag bin cover 2156 relative to the base station housing 210. This makes it possible to use 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 engagement accuracy of the first engaging member 2157 and the second engaging 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 can be a groove and a projection that match 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.

[0075] 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, an engagement structure, a mortise and tenon structure, or a screw structure.

[0076] As shown in Figures 21 and 22, in some feasible embodiments provided by this disclosure, the number of engaging portions 21572 is one or at least two, and the number of engaging portions 21572 can be reasonably determined depending on the specific structure and dimensions of the engaging portions 21572 to ensure the reliability and stability of the engagement between the first engaging member 2157 and the second engaging member 2158. Here, at least two engaging portions 21572 are spaced apart so that even if one engaging portion 21572 is damaged and deformed, the engagement between the non-deformable engaging portion 21572 and the second engaging member 2158 still ensures the reliability of the connection between the first engaging member 2157 and the second engaging member 2158, thereby extending the service life of the first engaging member 2157.

[0077] As shown in Figure 21, in the above embodiment, the retraction holes 21563 correspond one-to-one with the engaging 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 engaging portions 21572, reduces the impact of a deformed engaging portion 21572 on the adjacent engaging portion 21572, is advantageous in extending the service life of the entire first engaging member 2157, and consequently improves the reliability of the first engaging member 2157.

[0078] In one specific example, the engagement groove corresponds one-to-one with the engagement portion 21572, which is advantageous for improving the engagement reliability of the first engagement portion 21572 and the second engagement portion 21572, and consequently, can improve the engagement reliability of the dust bag bin cover 2156 and the base station housing 210.

[0079] As shown in Figure 18, in another specific example, all engaging portions 21572 correspond to a single engaging groove, which facilitates the machining of the engaging groove and is advantageous in reducing the manufacturing cost of the base station housing 210.

[0080] As shown in Figures 13, 14, and 15, in some feasible embodiments provided by this disclosure, the base station 200 further includes a dust bag bracket 270 provided in a dust bag bin 215, the dust bag bracket 270 being configured to mount a dust collection device 261, the dust bag bracket 270 being provided with a guide groove 271, the guide groove 271 being configured to guide the connection or disconnection of the dust collection device 261 and the dust bag bracket 270. That is, the guidance of the guide groove 271 on the dust bag bracket 270 enables quick and convenient fast attachment and detachment of the dust collection device 261 and the dust bag bracket 270, allowing for easy processing of the waste collected by the base station 200 and simplification of operation.

[0081] The provision of an anti-pinch structure 2711 on the groove wall of the guide groove 271 reduces the phenomenon of the dust collection device 261 getting caught or pinched in the guide groove 271. The installation of the anti-pinch structure 2711 allows the dust collection device 261 to be deployed smoothly and completely, and the dust collection device 261 has a large capacity. This avoids the problem of the dust collection device 261 getting caught in the guide groove 271 and affecting the circulation of the dust collection airflow, which is advantageous for improving the dust collection efficiency of the base station 200. The dust collection device 261 includes a dust bag body, which is made of a material that is breathable yet can filter fine particles, such as nonwoven fabric or paper material, and is configured to collect dust. In this disclosure, the dust collection device 261 getting caught on the groove wall of the guide groove 271 refers to the dust bag body getting caught on the side wall of the guide groove 271.

[0082] Here, as shown in Figures 13, 14, and 15, the opening of the guide groove 271 coincides with the direction of the opening of the dust bag bin 215, so that when the dust bag bin cover 2156 opens the opening of the dust bag bin 215, the dust collector 261 can be attached to or removed from the dust bag bracket 270 via the guide groove 271 through the opening of the dust bag bin 215. For example, if the opening of the dust bag bin 215 faces forward of the base station 200, the opening of the guide groove 271 also faces forward of the base station 200, so that the user can attach or remove the dust collector 261 to or from the dust bag bracket 270 via the guide groove 271 from the front of the base station 200, and within the dust bag bin 215, the user does not need to change the direction of their hand, making it ergonomically matched and easy to operate.

[0083] As shown in Figure 15, in some feasible embodiments provided by this disclosure, the guide groove 271 is inclined with respect to the vertical, where the vertical is the direction from the top to the bottom of the base station 200, for example, the length of the guide groove 271 is inclined with respect to the vertical, where the length of the guide groove 271 is indicated by arrow L in Figure 15, so that after the dust collection device 261 is attached to the dust bag bracket 270, the dust bag body of the dust collection device 261 hangs downward under the effect of gravity. Furthermore, the dust bag bracket 270 is located at the top of the dust bag bin 215, where the top of the dust bag bin 215 is indicated by the arrow in Figure 15, for example, the dust bag bracket 270 is located at one corner of the top of the dust bag bin 215.

[0084] Here, because the dust bag body is made of a soft material, during the process of attaching the dust collection device 261 to the dust bag bracket 270, the dust bag body sags due to gravity, and therefore, a situation occurs where the dust bag body gets caught on the lower groove wall of the guide groove 271, which may prevent the dust bag body from unfolding properly during the subsequent dust collection process. However, if the dust collection fan 264 is operating after the dust bag 216 has been attached to the dust bag bracket 270, the dust bag body will unfold under the action of the dust collection airflow. Typically, the dust collection device 261 is inserted and installed through the front end opening of the guide groove 271. The front end of the guide groove 271 is the surface facing the opening of the dust bag bin 215. Therefore, a notch structure is provided on the front end surface of the lower groove wall of the guide groove 271. The notch structure faces the opening of the dust bag bin 215 and is provided on the lower groove wall of the guide groove 271. This notch structure avoids the dust bag body, preventing a situation where part of the dust bag body gets caught in the guide groove 271 under the influence of gravity, and ensuring that the dust bag body unfolds smoothly and completely during the subsequent dust collection process.

[0085] Here, the notch structure may be a triangular notch, an arc-shaped notch, or a notch of other shape that satisfies the requirements. Furthermore, a transition surface that serves a guiding function is provided at the edge of the notch structure, for example, the transition surface may be a smooth curved surface or an inclined surface, so that the dust bag body falls smoothly under the action of gravity without getting caught on the groove wall of the guide groove 271.

[0086] As shown in Figures 16 and 17, in some feasible embodiments provided by this disclosure, a hollow chamber is provided inside the dust bag bracket 270, the hollow chamber includes a dust discharge port 2712 provided on the bracket side wall of the dust bag bracket 270 facing inward towards the dust bag bin 215, the dust discharge port 2712 is configured to dock with the inlet of a dust collection device 261. Here, the hollow chamber further includes a dust inlet port 2713 provided on the bracket side wall of the dust bag bracket 270 facing outward towards the dust bag bin 215, the dust bag bin 215 is provided with an air inlet 2151, and the dust inlet port 2713 is configured to dock with the air inlet 2151 of the dust bag bin 215.

[0087] In other words, the hollow chamber of the dust bag bracket 270 functions as part of the dust collection airflow path of the base station 200, and as the dust collection assembly 260 of the base station 200 operates, the dust collection airflow flows from the dust box 160 of the self-propelled cleaning machine 100 into the base station 200, through the airflow inlet 2151 of the dust bag bin 215 and the hollow chamber of the dust bag bracket 270 into the dust collection device 261, where the debris is collected and contained within the dust collection device 261.

[0088] As shown in Figure 17, the notch structure is provided at the connection point between the groove wall and the dust discharge port 2712. Normally, the dust bag body gets caught at the connection point between the groove wall of the guide groove 271 and the dust discharge port 2712. By providing the notch structure at this position, the occurrence of the dust bag body getting caught can be reduced. At the same time, normally, the dust bag body hangs down under the effect of gravity and gets caught on the bottom end of the dust discharge port 2712. Therefore, by providing the notch structure at least at the front bottom of the dust discharge port 2712, the occurrence of the dust bag body getting caught can be greatly reduced.

[0089] Specifically, a notch structure can be provided at the connection point between the front bottom of the dust discharge port 2712 and the lower groove wall of the guide groove 271, or, as shown in Figure 15, a notch structure can be provided at the connection point between the front bottom of the dust discharge port 2712 and the lower groove wall of the guide groove 271, and at the connection point between the front top and the lower groove wall of the guide groove 271. Here, the top-bottom direction in Figure 15 refers to the top-bottom direction of the base station.

[0090] As shown in Figures 14 and 16, in the above embodiment, the base station 200 further includes a sealing member 273 provided between the bag chamber side wall 21551 of the dust bag bin 215 and the bracket side wall where the dust entry port 2713 is located. The sealing member 273 seals the gap between the bag chamber side wall 21551 and the bracket side wall, thereby improving the sealing of the connection between the bag chamber side wall 21551 of the dust bag bin 215 and the bracket side wall of the dust bag bracket 270. This avoids the problem of inability to collect dust due to the inability to form negative pressure in the dust collection air passage because of airflow leakage between the bag chamber side wall 21551 and the bracket side wall of the dust bag bracket 270. At the same time, it avoids the problem of dust leaking out from the gap between the bag chamber side wall 21551 and the bracket side wall, which is advantageous in ensuring the smooth progress of the dust collection operation and ensuring a good dust collection effect.

[0091] Here, the sealing member 273 may be sealing cotton, a sealing ring, a sealing strip, or other sealing structure. Specifically, the sealing member 273 is sealing foam cotton, which is fixed to the bracket side wall by bolts and / or positioning posts, and then the sealing member 273 seals the gap between the bracket side wall and the bag chamber side wall 21551 by connecting the dust bag bracket 270 and the bag chamber side wall 21551.

[0092] As shown in Figure 17, in some feasible embodiments provided by this disclosure, the dust bag bracket 270 includes a sliding baffle 272 that slides along a guide groove 271, the sliding baffle 272 is configured to switch between a first position and a second position, in which case the sliding baffle 272 blocks the dust discharge port 2712 in response to the sliding baffle 272 being in the first position, and in which case the sliding baffle 272 exposes the dust discharge port 2712 in response to the sliding baffle 272 being in the second position. A dust collector 261 is a consumable and is removably attached to the dust bag bracket 270. Due to the design described above, when the dust bag bracket 270 is not attached to the dust collection device 261, the sliding baffle 272 blocks the dust discharge port 2712, isolating the dust bag bin 215 from the dust collection air passage. As a result, the suction force generated by the dust collection fan 264 cannot enter the dust bag bin 215, thus preventing dust from entering the dust bag bin 215 when the dust collection device 261 is not attached. As shown in Figure 16, the dust bag bracket 270 further includes an elastic part 274 connected to the sliding baffle 272, and the elastic part 274 is configured to hold the sliding baffle 272 in a first position. When the sliding baffle 272 is not subjected to external force, under the action of the elastic part 274, the sliding baffle 272 is in the first position, thereby blocking the dust discharge port 2712.

[0093] The dust bag 216 is configured to slide along the extension direction of the guide groove 271. When the dust collection device 261 is inserted into the guide groove 271 and slides along the guide groove 271 into the dust bag bin 251, the sliding baffle 272 slides along the extension direction of the guide groove 271 to attach the dust collection device 261 to the dust bag bracket 270, exposing the sliding baffle 272 from the dust discharge port 2712, and the opening of the dust bag 216 docks with the dust discharge port 2712. After the dust bag 216 is attached to the dust bag bracket 270, the dust bag 216 and dust bag bracket 270 are removed by pulling the dust bag outward from the dust bag bin 215, which causes the dust bag 216 to slide along the guide groove 271 and detach from the guide groove 271. At the same time, the sliding baffle 272 is reset to its initial position under the action of the elastic part 274, blocking the dust discharge port 2712.

[0094] As shown in Figure 17, in some feasible embodiments provided by this disclosure, a cutout structure is provided in the lower groove wall of the guide groove 271 away from the anti-pinch structure 2711, i.e., a cutout structure is provided in the dust bag bin 215 at an opening in the lower groove wall of the guide groove 271 away from the dust bag bin 215, the cutout structure is configured to expose a portion of the sliding baffle 272, the cutout structure may be an opening, and a guide structure 2714 is provided in the bottom wall of the bracket of the dust bag bracket 270, the guide structure 2714 is located on the side of the cutout structure away from the sliding baffle 272. The installation of the guide structure 2714 prevents the dust collection device 261 from shifting position, getting stuck, or protruding from the cutout structure within the guide groove 271 when it is inserted into the guide groove 271. Guided by the guide groove 271 and the guide structure 2714, the dust collection device 261 smoothly contacts the sliding baffle 272 on the dust bag bracket 270, causing the sliding baffle 272 to slide within the guide groove 271 and expose the dust discharge port 2712.

[0095] Here, the guide structure 2714 is a guide projection, and a guide slope is provided on the side of the guide projection facing the guide groove 271. Under the guiding action of the guide slope, the dust collection device 261 in the guide groove 271 can slide smoothly within the guide groove 271 and come into contact with the sliding baffle 272.

[0096] In a specific example, in the dust box 160 of the self-propelled cleaning device 100 provided in this disclosure, the filter unit 161 is detachably connected to the dust box 160. After the dust box 160 is removed from the main body 110 of the self-propelled cleaning device 100, the filter unit 161 can be removed from the dust box 160, and the dust inside the dust box 160 can be cleaned using the exhaust port, or the dust box can be washed.

[0097] In another specific example, the dustbin 160 includes a top wall, a bottom wall, and a dustbin side wall, and the waste storage chamber 162 has an opening, for example, the dustbin side wall encloses the waste storage chamber opening 1621, and the top wall of the dustbin is movably connected to the dustbin side wall to open and close the waste storage chamber opening 1621. After the dustbin 160 is removed from the main body 110 of the self-propelled cleaning machine 100, the dustbin 160 can be cleaned by opening the waste storage chamber opening 1621 from the top wall of the dustbin, for example, washing the dustbin 160, removing the waste inside the dustbin 160, or performing maintenance on the dustbin 160. After the dustbin top wall blocks the waste storage chamber opening 1621, the dustbin 160 can be attached to the main body 110 to perform dust collection operations.

[0098] As shown in Figures 4 and 6, in the dust box 160 provided by the embodiment of the present disclosure, the dust outlet 164 is provided on the side wall of the waste storage chamber 162, and the side wall of the waste storage chamber 162 on which the dust outlet 164 is located is inclined with respect to other side walls on the circumferential direction of the waste storage chamber 162, where the area around the waste storage chamber 162 may be understood as the area around the waste storage chamber opening 1621. That is, the dust outlet 164 is provided on one side wall around the opening of the waste storage chamber 162, and this side wall is inclined with respect to other side walls on the circumferential direction of the opening of the waste storage chamber 162, and the plane on which the dust outlet 164 is located is inclined with respect to other side walls on the circumferential direction of the waste storage chamber 162, thereby improving the smoothness of the airflow inside the dust box 160 when it is discharged from the dust outlet 164, and improving the airflow circulation efficiency inside the dust box 160.

[0099] As shown in Figures 3 and 6, by providing a flow guide member 165 in the waste storage chamber 162, the flow guide member 165 guides the airflow that flows into the intake port 163 to the dust discharge port 164. For example, the flow guide member 165 guides the dust collection airflow that flows into the intake port 163 to the dust discharge port 164. Furthermore, it avoids the problem of waste in the dust box 160 accumulating in the corners of the waste storage chamber 162 and not being collected, improving the thoroughness of collecting the waste in the dust box 160 to the base station 200 and improving the dust collection effect.

[0100] In the above embodiment, the air guide member 165 has an arc-shaped structure, and the arc-shaped air guide member 165 has a good airflow guiding effect, further improving the smoothness of the airflow in the dust box 160 when it is discharged from the dust outlet 164, improving the efficiency of dust collection airflow circulation in the dust box 160, and at the same time reducing the situation in which dust accumulates on the air guide member 165, which is advantageous in improving the thoroughness of collecting the dust in the dust box 160 to the base station 200.

[0101] As shown in Figures 3 and 6, the windward surface 1651 of the flow guide member 165 has a concave arc shape. This concave and arc shape expands the circulation space of the dust collection airflow between the intake port 163 and the dust discharge port 164 to some extent, which is advantageous in improving the smooth circulation of the dust collection airflow within the dust box 160. At the same time, the concave and arc-shaped windward surface 1651 allows the dust collection airflow flowing into the intake port 163 to be smoothly guided to the dust discharge port 164, and further guides the debris inside the dust box 160 to the dust discharge port 164 along with the dust collection airflow, which is advantageous in improving the dust collection effect.

[0102] As shown in Figures 3 and 6, in some feasible embodiments provided by this disclosure, the first end of the flow guide member 165 is connected to the side wall of the waste storage chamber 162 at the dust outlet 164, and the second end of the flow guide member 165 extends toward the intake port 163 and is connected to the side wall of the waste storage chamber 162. That is, the flow guide member 165 simultaneously acts as a baffle, dividing the internal space of the dust box 160 into two chambers that are isolated from each other, with the intake port 163 and the dust outlet 164 located within the chamber where the windward surface 1651 of the flow guide member 165 is located, or, in some examples, the dust box 160 is set to an irregular shape, and one side wall of the dust box 160 is configured as the flow guide member 165. As a result, the flow guide member 165 smoothly guides the dust collection airflow that flows into the intake port 163 to the dust discharge port 164, avoiding the problem of dust collection airflow flowing into the chamber or its location where the downwind surface 1652 of the flow guide member 165 is located, preventing it from being discharged from the dust discharge port 164, and causing dust to accumulate and making collection difficult. This significantly improves the thoroughness of collecting the dust in the dust box 160 to the base station 200.

[0103] At the same time, because the windward surface 1651 of the flow guide member 165 is concave and arc-shaped, the angle between the connection point between the two ends of the flow guide member 165 and the side wall of the waste storage chamber 162 becomes large, which can reduce or avoid the accumulation of waste.

[0104] As shown in Figures 4, 5, and 6, in some feasible embodiments provided by this disclosure, the side walls of the waste storage chamber 162 include sequentially connected first dustbin side wall 1611, second dustbin side wall 1612, third dustbin side wall 1613, fourth dustbin side wall 1614, and fifth dustbin side wall 1615, wherein the first dustbin side wall 1611 and the third dustbin side wall 1613 are opposite each other, the second dustbin side wall 1612 and the fifth dustbin side wall 1615 are opposite each other, and the fourth dustbin side wall 1614 is connected between the third dustbin side wall 1613 and the fifth dustbin side wall 1615. The dust outlet 164 is provided at an angle with respect to the side wall 1615, and is located on the fourth dust box side wall 1614. This ensures that the fourth dust box side wall 1614, where the dust outlet 164 is located, is provided at an angle with respect to the first dust box side wall 1611, the second dust box side wall 1612, the third dust box side wall 1613, and the fifth dust box side wall 1615. In other words, the dust outlet 164 is provided at an angle with respect to the first dust box side wall 1611, the second dust box side wall 1612, the third dust box side wall 1613, and the fifth dust box side wall 1615, which is advantageous for improving the smoothness of the dust collection airflow inside the dust box 160 when it is discharged from the dust outlet 164.

[0105] Here, the inclination angle between the fourth dust box side wall 1614 and the third dust box side wall 1613 is greater than 90° and less than 180°. This increases the inclination angle between the side wall of the dust box 160 in the waste storage chamber 162 where the dust outlet 164 is located and the side wall of the dust box 160 in the adjacent waste storage chamber 162. This facilitates the circulation of the dust collection airflow and reduces the accumulation of dust at the connection points between the fourth dust box side wall 1614 and the third dust box side wall 1613, and between the fourth dust box side wall 1614 and the fifth dust box side wall 1615.

[0106] In the above embodiment, the intake port 163 is provided on the second dust box side wall 1612, and the dust discharge port 164 is provided on the fourth dust box side wall 1614, which allows for smooth circulation of the dust collection airflow. Here, the dust entry port 166 is provided on the first dust box side wall 1611, and the exhaust port is provided on the third dust box side wall 1613, which allows for smooth circulation of the dust intake airflow.

[0107] As shown in Figure 6, one end of the flow guide member 165 is adjacent to one side of the dust discharge port 164 and is positioned at an angle of approximately 90° to the plane on which the dust discharge port 164 is located. This ensures that the dust collection airflow is guided by the flow guide member 165 and discharged from the dust discharge port 164 at an almost vertical angle.

[0108] As shown in Figure 3, in some feasible embodiments provided by this disclosure, within the main body 110 of the self-propelled cleaning machine 100, the dust outlet 164 and the dust exit 169 are connected via a dust discharge passage 168, where the dust discharge passage 168 is positioned at an angle of approximately 90° to the plane in which the dust outlet 164 is located, i.e., the direction of extension of the flow guide member 165 is approximately parallel to the direction of extension of the dust discharge passage 168. This allows the dust collection airflow in the dust box 160 to flow smoothly into the dust discharge passage 168 guided by the flow guide member 165, reducing the accumulation and clogging of debris in the dust box 160 at the connection point between the dust outlet 164 and the dust discharge passage 168, improving the thoroughness of collecting the debris in the dust box 160 to the base station 200, and is advantageous for improving the dust collection effect.

[0109] As shown in Figure 2, the self-propelled cleaning machine 100 provided in this disclosure includes a wet cleaning system comprising a cleaning assembly, a water supply mechanism, a liquid storage tank, etc. Here, the cleaning assembly is located below the liquid storage tank, and the cleaning fluid inside the liquid storage tank is transported to the cleaning assembly via the water supply mechanism, thereby allowing the cleaning assembly 180 to wet clean the surface to be cleaned. In other embodiments of this disclosure, the cleaning fluid inside the liquid storage tank is sprayed directly onto the surface to be cleaned, and the cleaning assembly 180 uniformly applies the cleaning fluid 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.

[0110] The cleaning assembly 180 provided in the embodiments of this disclosure includes a motion mechanism and a cleaning element 183 provided on the equipment body 110, i.e., the entire cleaning assembly 180 is attached to the equipment body 110 via the motion mechanism, and the cleaning assembly 180 moves with the movement of the equipment 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.

[0111] 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.

[0112] As shown in Figures 23 and 24, in some feasible embodiments provided by this disclosure, the base station 200 further includes a washing plate 220, which is mounted on the bottom wall of the housing chamber 211 and is configured to interfere with the cleaning element 183 of the self-propelled cleaning machine 100 to remove dirt from the cleaning element 183. This allows the washing plate 220 to perform a cleaning operation on the cleaning element 183 when the self-propelled cleaning machine 100 is docked in the housing chamber 211 of the base station 200, converting the dirty cleaning element 183 into a clean cleaning element 183 that can be used for the next mopping.

[0113] As shown in Figure 23, in some feasible embodiments provided by this disclosure, the cleaning plate 220 is detachably connected to the base station 200, thereby allowing the entire cleaning plate 220 to be removed from the base station 200 for cleaning, which is advantageous for improving the thoroughness of the cleaning plate 220, avoiding the possibility of insufficient cleaning or difficulty in cleaning, which could lead to dirt remaining on the cleaning plate 220 for extended periods and causing unpleasant odors, thus improving the cleaning experience of the cleaning plate 220 and improving user satisfaction. At the same time, the detachable connection of the cleaning plate 220 to the base station 200 is advantageous for improving maintenance efficiency.

[0114] Here, as shown in Figure 23, the cleaning platen 220 includes a cleaning chamber 2211 and a cleaning unit 222 provided inside the cleaning chamber 2211. The cleaning unit 222 is configured to interfere with the cleaning element 183 of the self-propelled cleaning device 100 to remove dirt from the cleaning element 183, thereby enabling the cleaning operation of the cleaning element 183. For example, if the cleaning element 183 is a mop plate, the cleaning operation of the mop plate is enabled by the interference between the mop plate and the cleaning unit 222 in the cleaning chamber 2211. Since the cleaning chamber 2211 is used to contain the dirt, the cleaning unit 222 accumulates the dirt inside the cleaning chamber 2211 after removing the dirt from the cleaning element 183.

[0115] The cleaning panel 220 is detachably connected to the base station 200, so that the entire cleaning panel 220 is detachably connected to the base station 200, and the user can attach or detach the cleaning panel 220 to or from the base station 200 as needed. For example, the user can detach the entire cleaning panel 220 from the base station 200, making it easier to clean the cleaning panel 220, improving the convenience of cleaning the cleaning panel 220, improving the thoroughness of cleaning the cleaning panel 220, preventing dirt from accumulating or remaining in the cleaning chamber 2211 for a long period of time and generating unpleasant odors, and thus improving user satisfaction.

[0116] As shown in Figure 23, in some feasible embodiments provided by this disclosure, a wastewater tank 2212 is provided in the bottom wall of the cleaning chamber 2211, the groove bottom of the wastewater tank 2212 is lower than the top surface of the bottom wall of the cleaning chamber 2211, and after the cleaning unit 222 removes dirt from the cleaning element 183, the dirt accumulates in the wastewater tank 2212 under the action of gravity. Here, the cleaning platen 220 further includes a wastewater pipe 223, which is provided in the cleaning platen 220, with a first end of the wastewater pipe 223 communicating with the wastewater tank 2212 and a second end of the wastewater pipe 223 extending outside the cleaning chamber 2211. This allows the wastewater pipe 223 to discharge dirt from the wastewater tank 2212, allowing immediate discharge of dirt from the cleaning chamber 2211, while the cleaning chamber 2211 continues to contain dirt, enabling continuous cleaning of the cleaning element 183 and improving the cleaning effect. At the same time, this is advantageous in improving user satisfaction by preventing the dirt in the washing chamber 2211 from overflowing and causing secondary contamination due to not being immediately discharged.

[0117] In the above embodiment, the base station 200 includes a wastewater tank 214, and the second end of the wastewater pipe 223 communicates with the wastewater tank 214, allowing waste to be collected in the wastewater tank 214. A water pump is provided in the pipeline connecting the wastewater pipe 223 and the wastewater tank 214 to enable wastewater collection.

[0118] As shown in Figures 8 and 23, in some feasible embodiments provided by the Disclosure, the cleaning platen 220 further includes a water guide section 224, which is provided on the inner bottom wall of the cleaning chamber 2211 and protrudes from the surface of the cleaning chamber 2211, i.e., the water guide section 224 is understood to be a water guide rib, and a water guide tank 2241 is provided at the top of the water guide section 224, which communicates with a water outlet 2112 on the base station 200, and the water guide tank 2241 is set to contain cleaning fluid and interfere with the cleaning element 183. Thus, the cleaning fluid flows from the water outlet 2112 of the base into the water guide tank 2241, and when the cleaning element 183 interferes with the water guide tank 2241, it wets itself with the cleaning fluid in the water guide tank 2241, and then the cleaning element 183 can be cleaned by interfering with the cleaning section, which is advantageous in improving the cleaning effect of the cleaning element 183. Here, the water guide section 224 protrudes from the surface of the cleaning chamber 2211, and the water guide tank 2241 on the water guide section 224 reliably interferes with the cleaning element 183, ensuring that the cleaning element 183 is smoothly moistened with water from the water guide tank 2241.

[0119] Here, as shown in Figure 24, the water intake section 224 is provided with a liquid leak port 2242 that communicates with the water intake tank 2241. After the cleaning liquid flows into the water intake tank 2241 of the water intake section 224, the cleaning element 183 of the self-propelled cleaning equipment 100 cannot completely suck up the cleaning liquid in the water intake tank 2241, and there is a possibility that cleaning liquid will remain in the water intake tank 2241. By providing a liquid leak port 2242 that communicates with the water intake tank 2241 in the water intake section 224, the cleaning liquid remaining in the water intake tank 2241 can be discharged from the liquid leak port 2242, thus avoiding a situation where liquid remains in the water intake tank 2241 for a long period of time and generates an unpleasant odor, and is also advantageous in improving the cleanliness of the water intake tank 2241. Note that the water intake section 224 and the cleaning section 222 may be cleaned simultaneously during the process of removing the cleaning plate 220 from the base station 200 and cleaning it.

[0120] As shown in Figures 7 and 8, the clean water tank 213 is located above the containment chamber 211 and is used to contain the cleaning solution. The water outlet 2112 communicates with the clean water tank 213 and can transport the cleaning solution in the clean water tank 213 into the water conduit tank 2241. Here, the water outlet 2112 is located at the top of the containment chamber 211 and faces the water conduit tank 2241 of the water conduit section 224. By controlling the opening and closing of the water outlet 2112 with a valve or other component, the cleaning solution in the clean water tank 213 is transported into the water conduit tank 2241 under the influence of gravity. Alternatively, the water outlet 2112 can be located on the side wall of the containment chamber and connected to the water conduit tank 2241 via a pipeline, allowing the cleaning solution in the cleaning box to flow into the water conduit tank 2241.

[0121] 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. [Explanation of symbols]
