[0030] 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.

[0031] 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.

[0032] In this disclosure, "provided at a 90° angle" refers to a state in which the corresponding structure is provided at an angle of approximately 90° within the allowable error range for processes, measurements, etc. The allowable error range for such processes and measurements is determined according to the actual operation, and is not limited to, for example, within ±10%.

[0033] 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.

[0034] As shown in Figures 1 to 19, 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.

[0035] 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.

[0036] 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.

[0037] 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).

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] In one specific example, the filtration unit 161 is detachably connected to the dust box 160. After removing the dust box 160 from the main body 110 of the self-propelled cleaning device 100, the filtration 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 1601, or the dust box can be washed.

[0050] In another specific example, the dustbin 160 has a top wall, a bottom wall, and dustbin side walls, and the waste storage chamber 162 has an opening, for example, the waste storage chamber opening is surrounded by the dustbin side walls, and the top wall of the dustbin is movably connected to the dustbin side walls to open and close the waste storage chamber opening. After removing the dustbin 160 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 with the top wall of the dustbin, allowing for operations such as washing the dustbin 160, discharging the waste inside the dustbin 160, or performing maintenance on the dustbin 160. After closing the waste storage chamber opening with the top wall of the dustbin, the dustbin 160 can be attached to the main body 110 and dust collection operations can be performed.

[0051] As shown in Figures 4 and 6, in the dust box 160 provided by the embodiment of the present disclosure, a dust outlet 164 is provided in 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 in the circumferential direction of the waste storage chamber 162, where the circumferential side of the waste storage chamber 162 is understood to be the circumferential side of the opening of the waste storage chamber. That is, the dust outlet 164 is provided in one side wall on the circumferential side of the opening of the waste storage chamber 162, and this side wall is inclined with respect to other side walls on the circumferential side of the opening of the waste storage chamber 162, so that the plane on which the dust outlet 164 is located is inclined with respect to other side walls in the circumferential direction of the waste storage chamber 162, and as a result the smoothness of the airflow in the dust box 160 being discharged through the dust outlet 164 is improved, and the airflow circulation efficiency in the dust box 160 is improved.

[0052] As shown in Figures 3 and 6, by providing a flow guide member 165 in the waste storage chamber 162 and guiding the airflow that flows into the intake port 163 to the dust discharge port 164 using the flow guide member 165, the problem of waste in the dust box 160 accumulating in the corners of the waste storage chamber 162 and not being collected can be avoided, the thoroughness of collecting the waste in the dust box 160 to the base station 200 can be improved, and the dust collection effect can be improved.

[0053] In the above embodiment, the air guide member 165 has an arc-shaped structure, and the arc-shaped air guide member 165 effectively guides the airflow, further improving the smoothness of the airflow in the dust box 160 when it is discharged through the dust outlet 164, improving the airflow circulation efficiency in the dust box 160, and at the same time reducing the occurrence of situations in which dust accumulates on the air guide member 165, which is advantageous in further improving the thoroughness of collecting the dust in the dust box 160 to the base station 200.

[0054] Here, 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 airflow circulation space between the air intake port 163 and the dust outlet port 164 to some extent, which is advantageous in improving the smoothness of airflow circulation within the dust box 160. At the same time, the concave and arc-shaped windward surface 1651 smoothly guides the airflow that flows into the air intake port 163 to the dust outlet port 164, and further guides the debris inside the dust box 160 to the dust outlet port 164 along with the airflow, which is advantageous in improving the dust collection effect.

[0055] 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 where the dust outlet 164 is located, and the second end of the flow guide member 165 extends toward the intake port 163 and is also connected to the side wall of the waste storage chamber 162. That is, the flow guide member 165 also acts as a baffle, dividing the internal space of the dust box 160 into two isolated chambers, 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 set as the flow guide member 165. This allows the airflow guide member 165 to smoothly guide the airflow that flows into the intake port 163 to the dust discharge port 164, avoiding the problem of airflow flowing into the chamber or its location where the downwind surface 1652 of the airflow guide member 165 is located, preventing smooth discharge from the dust discharge port 164, and causing dust to accumulate and become difficult to collect. This significantly improves the thoroughness of collecting the dust in the dust box 160 to the base station 200.

[0056] 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, thereby reducing or avoiding the accumulation of waste.

[0057] 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, the fourth dustbin side wall 1614 is connected between the third dustbin side wall 1613 and the fifth dustbin side wall 1615, and the third dustbin side wall 1613 and the fifth dustbin The dust outlet 164 is provided at an angle with respect to the side wall 1615 of the dust box, and is opened in the side wall 1614 of the fourth dust box. As a result, the side wall 1614 of the fourth dust box where the dust outlet 164 is located is provided at an angle with respect to the side wall 1611 of the first dust box, the side wall 1612 of the second dust box, the side wall 1613 of the third dust box, and the side wall 1615 of the fifth dust box. In other words, the dust outlet 164 is provided at an angle with respect to the side wall 1611 of the first dust box, the side wall 1612 of the second dust box, the side wall 1613 of the third dust box, and the side wall 1615 of the fifth dust box. This is advantageous in improving the smoothness of the airflow inside the dust box 160 when it is discharged through the dust outlet 164.

[0058] 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°. As a result, 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 adjacent waste storage chamber 162 dust box 160 is large, which is advantageous for airflow circulation and prevents dust from accumulating 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.

[0059] In the above embodiment, the intake port 163 is opened in the side wall 1612 of the second dust box, and the dust discharge port 164 is opened in the side wall 1614 of the fourth dust box, allowing the dust collection airflow to circulate smoothly. Here, the dust entry port 166 is opened in the side wall 1611 of the first dust box, and the exhaust port 1601 is opened in the side wall 1613 of the third dust box, allowing the dust intake airflow to circulate smoothly.

[0060] As shown in Figure 6, one end of the flow guide member 165 is positioned adjacent to one side of the dust discharge port 164 and at a 90° angle to the plane on which the dust discharge port 164 is located, so that the dust collection airflow is discharged from the dust discharge port 164 at a nearly vertical angle under the guidance of the flow guide member 165.

[0061] 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, a dust outlet 164 and a dust exit 169 are connected via a dust discharge passage 168, where the distance between the dust discharge passage 168 and the plane in which the dust outlet 164 is located is 90°, that is, the extension direction of the flow guide member 165 is approximately parallel to the extension direction of the dust discharge passage 168. As a result, the dust collection airflow in the dust box 160 flows smoothly into the dust discharge passage 168 guided by the flow guide member 165, reducing the accumulation of debris in the dust box 160 or clogging at the connection point between the dust outlet 164 and the dust discharge passage 168, improving the thoroughness of collecting debris in the dust box 160 to the base station 200, and is advantageous in improving the dust collection effect.

[0062] As shown in Figures 7 and 8, 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.

[0063] As shown in Figures 9, 10, and 12, 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.

[0064] Here, in the dust collection assembly 260 of the base station 200 provided in the embodiment of the present disclosure, specifically as shown in Figure 9, 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.

[0065] Here, as shown in Figures 13 and 14, 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 7. As shown in Figures 7 and 8, the base station 200 further includes a dust bag bin cover 2156, and 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, the opening of the dust bag bin 215 is also sealed, and the dust bag bin 215 becomes a sealed chamber, generating negative pressure in the dust collection air duct, ensuring reliable dust collection. When the dust bag bin cover 2156 opens the opening of the dust bag bin 215, the dust collection device 261 inside the dust bag bin 215 can be easily replaced. Here, as shown in Figures 13, 14, 15, and 17, 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.

[0066] 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.

[0067] In some feasible embodiments provided by this disclosure, as shown in Figure 12, an air outlet 2119 is further provided 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 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.

[0068] 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 passage for the dust collection airflow between the air outlet 2621 and the air outlet 2119 becomes a winding passage, ensuring a good noise reduction effect.

[0069] Here, the air outlet 2119 may be opened in 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 opened in 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 located away from the air outlet 2621.

[0070] 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 airflow at the air outlet end 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.

[0071] Furthermore, the second sound-absorbing member 2641 is configured to filter the airflow at the air outlet end 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 performs noise reduction and re-filters the dust collection airflow, significantly reducing the operating noise of the dust collection fan 264 while also improving the cleanliness of the airflow discharged to the external environment by filtering the airflow that flows out from the air outlet end of the dust collection fan 264.

[0072] 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.

[0073] 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.

[0074] Here, a vortex flow chamber 2642 and a transition chamber 2643 are provided, communicating with the vortex fan via an air vent 2644. The air inlet end is opened in the inner wall of the vortex flow chamber 2642, and the air outlet end is opened in the inner wall of the transition chamber 2643. The second sound-absorbing member 2641 is located inside the vortex flow chamber 2642. As a result, the second sound-absorbing member 2641 can absorb and filter the dust-collecting airflow flowing from the vortex flow chamber 2642 into the transition chamber 2643.

[0075] 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 collector 261 communicates with the air inlet 2151, the air inlet end of the 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 the noise reduction housing 262 via a second dust collection pipeline 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 pipeline 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 pipeline 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 is then collected. 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 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.

[0076] 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 negative pressure from forming in the dust collection duct. 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 operation of the dust collection process and a good dust collection effect. Specifically, the sealing section may be made of an elastic material.

[0077] 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 opened in the side wall of the housing chamber 211, and the decorative opening 21151 and the dust collection opening 2115 are distributed 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 distributed 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 equipment 100 to enter the base station When docked at base 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.

[0078] 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.

[0079] 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.

[0080] 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 that connects the dust box 160 and the dust outlet 169. 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, and the dust collection assembly 260 communicating with the dust collection port 2115, so that when the self-propelled cleaning machine 100 is docked at the base station 200 and the dust outlet 169 of the self-propelled cleaning machine 100 is docked with the dust collection port 2115 on the base station 200, the dust collection assembly 260 on the base station 200 operates, and airflow flows into the base station 200 from the docked dust outlet 169 and dust collection port 2115 through the dust box 160 and dust discharge passage 168, and further collects the debris in the dust box 160 into the base station 200, thereby realizing a dust collection operation. Specifically, a storage chamber 211 is provided in the base station 200, and when the self-propelled cleaning equipment 100 is parked at the base station 200, at least a portion of the self-propelled cleaning equipment 100 is housed in the storage chamber 211, and the dust collection port 2115 is located inside the storage chamber 211, specifically, the dust collection port 2115 is located on the side wall of the storage chamber 211.

[0081] As shown in Figures 13, 14, 15, and 17, in some feasible embodiments provided by this disclosure, the base station 200 further includes a dust bag supporter 270 provided in a dust bag bin 215, the dust bag supporter 270 configured to attach a dust collection device 261, the dust bag supporter 270 is provided with a guide groove 271, the guide groove 271 configured to guide the connection or disconnection of the dust collection device 261 and the dust bag supporter 270. That is, the guidance of the guide groove 271 on the dust bag supporter 270 enables quick and convenient fast attachment and detachment of the dust collection device 261 and the dust bag supporter 270, allowing for easy processing of the waste collected by the base station 200 and simplification of operation.

[0082] 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.

[0083] Here, as shown in Figures 18 and 19, the opening of the dust bag bin 215 is located at the front of the base station 200, where the front of the base station is shown in Figure 7, i.e., the dust bag bin 215 is provided at the front of the base station 200, and the opening of the guide groove 271 coincides with the direction of the opening of the dust bag bin 215, thereby allowing the dust collection device 261 to be attached to the dust bag supporter 270 via the guide groove 271, or to the dust bag via the guide groove 271. When the dust bag bin 215 is removed from the supporter 270, 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, thereby allowing the user to attach the dust collection device 261 to the dust bag supporter 270 or remove it from the dust bag supporter 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 ergonomic and easy to operate.

[0084] In the above embodiment, as shown in Figures 5, 7, 18, and 19, the base station 200 further includes a dust bag bin cover 2156, the dust bag bin 215 is located at the front of the base station housing 210, and the dust bag bin cover 2156 is detachably connected to the base station housing 210 and can block or open the opening of the dust bag bin 215. Specifically, the dust bag bin cover 2156 and the base station housing 210 are detachable via a locking assembly, and the dust collection device 261 can be attached and detached by opening the opening of the dust bag bin 215. Because the locking assembly has a simple structure and low cost, it simplifies the structure of the base station 200 and is advantageous in reducing the manufacturing cost of the base station 200 compared to the method in related technologies in which the dust collection device 261 is placed in a pull-out drawer on the base station 200. 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 2156 and the base station housing 210 are connected via a magnetic attraction assembly, making it suitable for widespread adoption and application.

[0085] As shown in Figure 18, 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 18, so that after the dust collection device 261 is attached to the dust bag supporter 270, the dust bag body of the dust collection device 261 hangs downward under the effect of gravity. Furthermore, the dust bag supporter 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 18, for example, the dust bag supporter 270 is located at one corner of the top of the dust bag bin 215.

[0086] 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 supporter 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 supporter 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.

[0087] 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.

[0088] As shown in Figures 16 and 17, in some feasible embodiments provided by this disclosure, a hollow chamber is provided inside the dust bag supporter 270, the hollow chamber includes a dust discharge port 2712 provided on the supporter side wall of the dust bag supporter 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 supporter side wall of the dust bag supporter 270 facing outward towards the dust bag bin 215, where, as shown in Figure 14, the dust bag bin 215 is provided with an airflow inlet 2151, and the dust inlet port 2713 is configured to dock with the airflow inlet 2151 of the dust bag bin 215.

[0089] In other words, the hollow chamber of the dust bag supporter 270 functions as part of the dust collection air duct 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 supporter 270 into the dust collection device 261, where the debris is collected and contained within the dust collection device 261.

[0090] 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. By distributing 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.

[0091] 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 18, 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 18 refers to the top-bottom direction of the base station.

[0092] 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 supporter 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 supporter side wall, thereby improving the sealing of the connection between the bag chamber side wall 21551 of the dust bag bin 215 and the supporter side wall of the dust bag supporter 270. This avoids the problem of dust not being able to be collected because negative pressure cannot be formed in the dust collection airway due to airflow leakage between the bag chamber side wall 21551 and the supporter side wall of the dust bag supporter 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 supporter side wall, which is advantageous in ensuring the smooth progress of the dust collection operation and ensuring a good dust collection effect.

[0093] 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 supporter side wall by bolts and / or positioning posts, and then the sealing member 273 seals the gap between the supporter side wall and the bag chamber side wall 21551 by connecting the dust bag supporter 270 and the bag chamber side wall 21551.

[0094] As shown in Figure 17, in some feasible embodiments provided by this disclosure, the dust bag supporter 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 supporter 270. Due to the design described above, if the dust bag supporter 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 duct. 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 supporter 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.

[0095] 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 supporter 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 supporter 270, the dust bag 216 and dust bag supporter 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.

[0096] 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 supporter of the dust bag supporter 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 supporter 270, causing the sliding baffle 272 to slide within the guide groove 271 and expose the dust discharge port 2712.

[0097] 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.

[0098] As shown in Figure 13, the dust bag bin 215 is provided with an air outlet 2152, which is connected to a dust collection fan 214. Typically, in order to improve space utilization and dust bag capacity, the dust bag is 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 the dust bag, which was not initially in contact with the air outlet, to stretch, and its bottom can cover the air outlet, potentially causing clogging. Therefore, in some feasible embodiments provided by this disclosure, a plurality of support parts 2154 are provided within the dust bag bin 215, the plurality of support parts 2154 are distributed around the air outlet 2152 at intervals, and support at least some of the dust collection devices 261, and the installation of the support parts 2154 prevents the dust collection devices 261 from completely covering the air outlet 2152, promotes the flow of the dust collection airflow, prevents clogging, and is advantageous for improving dust collection efficiency.

[0099] 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.

[0100] 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.

[0101] 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.
