However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present disclosure thorough and complete, and to fully convey the concepts of these exemplary embodiments to those having ordinary knowledge in the art.

As shown in Figures 1 to 24, the embodiments of the present disclosure provide a base station 200 and a cleaning robot system, wherein the cleaning robot system includes a self-moving cleaning device 100 and a base station 200, that is, the base station 200 is used in conjunction with the self-moving cleaning device 100.

Further, as shown in FIG. 1 and FIG. 2 , the self-moving cleaning device 100 may include a machine body 110, a sensing system 120, a control module, a drive system 140, a cleaning system 150, an energy system, and a human-computer interaction system 170. It is understandable that the self-moving cleaning device 100 may be an automatic cleaning device or other self-moving cleaning devices that meet the requirements. The self-moving cleaning device 100 is a device that automatically performs cleaning operations in a certain area to be cleaned without user operation. Among them, when the self-moving cleaning device 100 starts working, the self-moving cleaning device 100 starts from the base station 200 to perform the cleaning task. When the self-moving cleaning device 100 completes the cleaning task or other situations require the termination of the cleaning task, the self-moving cleaning device 100 can return to the base station 200 for charging, and/or water replenishment, and/or cleaning, and/or dust collection, etc.

As shown in FIG. 1 , the machine body 110 includes a forward portion 111 and a rearward portion 112, which have an approximately circular shape or other shapes, including but not limited to an approximately D-shaped shape with a front and rear circle and a rectangular or square shape with a front and rear circle.

As shown in FIG1 , the sensing system 120 includes a position determination device 121 located on the machine body 110, a collision sensor and a proximity sensor arranged on the buffer 122 of the forward part 111 of the machine body 110, a cliff sensor arranged at the bottom of the machine body 110, and a magnetometer, accelerometer, gyroscope, odometer and other sensing devices arranged inside the machine body 110, which are used to provide various position information and motion status information of the machine to the control module. The position determination device 121 includes but is not limited to a camera and a laser distance sensor (LDS, full name Laser Distance Sensor).

As shown in FIG. 1 , the forward portion 111 of the machine body 110 can carry the buffer 122. During the cleaning process, the driving wheel module 141 propels the self-propelled cleaning device 100 to walk on the ground. The buffer 122 detects one or more events in the driving path of the self-propelled cleaning device 100 through a sensor system, such as an infrared sensor, disposed thereon. The self-propelled cleaning device 100 can control the driving wheel module 141 to make the self-propelled cleaning device 100 respond to the event, such as staying away from the obstacle, through the event detected by the buffer 122, such as an obstacle or a wall.

The control module is disposed on a circuit board in the machine body 110, and includes a computing processor, such as a central processing unit and an application processor, that communicates with a non-volatile memory, such as a hard drive, a flash memory, or a random access memory. The application processor utilizes a positioning algorithm, such as a real-time positioning and mapping algorithm (SLAM, full name Simultaneous Localization And Mapping), based on obstacle information fed back by a laser ranging device to draw a real-time map of the environment in which the self-moving cleaning device 100 is located. In addition, the distance information and speed information fed back by the sensors, cliff sensors, magnetometers, accelerometers, gyroscopes, odometers and other sensing devices installed on the buffer 122 are combined to comprehensively judge the current working state and location of the self-moving cleaning device 100, as well as the current location of the self-moving cleaning device 100, such as passing the threshold, being on the carpet, being on the cliff, being stuck above or below, the dust box is full, being picked up, etc., and specific next action strategies are given for different situations, so that the self-moving cleaning device 100 has better cleaning performance and user experience.

As shown in FIG. 1 and FIG. 2 , the drive system 140 can control the machine body 110 to travel across the ground based on a drive command having distance and angle information, such as x, y, and θ components. As shown in FIG. 1 , x and y are two axes representing rectangular coordinates, and θ is the pitch angle of the xy plane. The drive system 140 includes a drive wheel module 141, and the drive wheel module 141 can control the left wheel and the right wheel at the same time. In order to more accurately control the movement of the machine, it is preferred that 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 transverse axis defined by the machine body 110. In order to enable the self-propelled cleaning device 100 to move more stably or have stronger mobility on the ground, the self-propelled cleaning device 100 may include one or more driven wheels 142, and the driven wheels 142 include but are not limited to universal wheels. The driving wheel module 141 includes a travel wheel and a driving motor and a control circuit for controlling the driving motor. The driving wheel module 141 can also be connected to a circuit and an odometer for measuring the driving current. The driving wheel can have a biased drop-down suspension system, which is fastened in a movable manner, for example, attached to the machine body 110 in a rotatable manner, and receives a spring bias that is biased downward and away from the machine body 110. The spring bias allows the drive wheel to maintain contact and traction with the ground with a certain ground force, while the self-propelled cleaning device 100 also includes a cleaning element 183, which also contacts the ground with a certain pressure.

The energy system includes a rechargeable battery, such as a nickel-metal hydride battery and a lithium battery. The rechargeable battery can be connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit, and the charging control circuit, the battery pack charging temperature detection circuit, and the battery undervoltage monitoring circuit are further connected to the single-chip control circuit. The host is connected to the base station 200 through a charging electrode arranged on the side or bottom of the fuselage for charging.

The human-machine interaction system 170 includes buttons on the host panel for users to select functions; it may also include a display screen and/or indicator lights and/or speakers, which display the current state of the machine or function options to the user; it may also include a mobile client program. For the path navigation type self-moving cleaning device 100, the mobile client can display a map of the environment where the device is located and the location of the machine to the user, which can provide the user with more abundant and humanized functions.

As shown in FIG2 , the cleaning system 150 includes a dry cleaning system 151, that is, the self-propelled cleaning device 100 can be a sweeper, or the cleaning system 150 includes a wet cleaning system and a dry cleaning system 151, that is, the self-propelled cleaning device 100 can be a sweeper-mopper.

As shown in FIG. 2 , the dry cleaning system 151 provided in the disclosed embodiment may include a roller brush, a dust box, and a dust suction fan. The roller brush that has a certain interference with the ground sweeps up the garbage on the ground and rolls it to the front of the dust suction port between the roller brush and the dust box, and then the gas with suction generated by the dust suction fan and passing through the dust box is sucked into the dust box. The dry cleaning system 151 may also include a side brush 152 with a rotating shaft, which is at a certain angle relative to the ground to move the debris into the roller brush area of the cleaning system 150.

As shown in Figures 3, 4, 5, and 6, the self-moving cleaning device 100 provided in the disclosed embodiment has a dust box 160 provided with a garbage storage chamber 162, and an air inlet 163 and a dust outlet 164 connected to the garbage storage chamber 162. The dust box 160 is also provided with a dust inlet 166 and an air outlet 1601 connected to the garbage storage chamber 162. The dust inlet 166 is connected to the dust suction port of the self-moving cleaning device 100 through a dust suction pipe. The dust suction fan of the self-moving cleaning device 100 is connected to the air outlet 1601 of the dust box 160. A filter 161 is provided at the air outlet 1601. The suction airflow generated by the dust suction fan will remove the dust to be removed. The garbage on the cleaned surface is sucked into the dust box 160 through the dust suction port, the dust suction pipe, and the dust inlet 166, and after being filtered by the filter 161 at the exhaust port 1601, the dust suction airflow is discharged from the exhaust port 1601 through the dust suction fan. Thus, the garbage can be stored in the dust box 160, and the setting of the filter 161 can prevent the garbage in the dust box 160 from entering the dust suction fan, which is beneficial to improve the service life of the dust suction fan.

It should be noted that, as shown in FIG. 3 , the machine body 110 of the self-moving cleaning device 100 is also provided with a dust outlet 169, and a dust exhaust passage 168 connecting the dust outlet 164 and the dust outlet 169 is provided inside the machine body 110. The base station 200 is provided with a dust collecting port 2115 and a dust collecting assembly 260 connected to the dust collecting port 2115. When the self-moving cleaning device 100 is docked on the base station 200, and the self-moving cleaning device 100 is After the dust outlet 169 of the device 100 is connected to the dust collecting port 2115 on the base station 200, the dust collecting assembly 260 on the base station 200 works, and the airflow flows in from the air inlet 163 of the dust box 160, passes through the dust outlet 164, the dust exhaust channel 168, and flows into the base station 200 from the connected dust outlet 169 and the dust collecting port 2115, thereby collecting the garbage in the dust box 160 in the base station 200, thereby realizing the dust collection operation.

Among them, the air inlet 163 of the dust box 160 and the dust outlet 164 of the dust box 160 are both provided with one-way valves. When cleaning the impurities in the dust box 160, that is, in the process of the base station 200 collecting dust on the self-moving cleaning device 100, the air inlet 163 and the dust outlet 164 of the dust box 160 are opened to make it easier for the airflow generated in the dust box 160 to take away the impurities therein. Among them, the specific structure of the dust box 160 will be described in detail later.

As shown in Figures 7 and 8, the base station 200 provided in the present disclosure includes a base station housing 210 and a dust collection assembly 260, and the base station housing 210 is provided with a dust collection port 2115. When the self-moving cleaning device 100 is docked on the base station 200, the dust outlet 169 of the self-moving cleaning device 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 receiving chamber 211, and when the self-moving cleaning device 100 is docked on the base station 200, at least part of the self-moving cleaning device 100 is accommodated in the receiving chamber 211, and the dust collection port 2115 is located in the receiving chamber 211. Specifically, the dust collection port 2115 can be located on the side wall of the receiving chamber 211.

As shown in FIG9, FIG10 and FIG13, the dust collecting assembly 260 includes a dust collecting device 261, a dust bag bin 215, a noise reduction housing 262, a dust collecting pipe 263 and a dust collecting fan 264 arranged in the base station housing 210, wherein the dust collecting device 261 is arranged in the dust bag bin 215, the noise reduction housing 262 is provided with an exhaust port 2621, and the dust collecting pipe 263 is connected to the dust collecting port 2115, the dust bag bin 215, and the noise reduction housing 262. 5. The noise reduction shell 262 is used to form a dust collecting air duct. The dust collecting fan 264 is arranged on the dust collecting air duct to generate a dust collecting airflow. The dust collecting airflow generated by the dust collecting fan 264 brings the garbage in the dust box 160 of the self-moving cleaning device 100 into the dust bag collecting device 261 through the dust collecting port 2115. The garbage is collected and intercepted by the dust collecting device 261 and then contained in the dust collecting device 261. The dust collecting airflow is discharged from the exhaust port 2621. Since the dust-collecting airflow generated by the dust-collecting fan 264 will be discharged through the exhaust port 2621 on the noise reduction shell 262, the noise reduction shell 262 can perform noise reduction treatment on the dust-collecting airflow passing through it, so the dust-collecting airflow in the dust-collecting air duct will be discharged after being noise-reduced by the noise reduction shell 262, thereby greatly reducing the pneumatic noise of the dust-collecting fan 264, reducing the working noise of the fan, and improving the comfort of the user. Among them, the dust collection device 261 can be a dust bag, or other components that meet the requirements.

Specifically, as shown in FIG. 9 , the dust collecting duct 263 includes a first dust collecting duct 2631 and a second dust collecting duct 2632 . The first dust collecting duct 2631 is connected to the dust collecting port 2115 and the dust bag bin 215 , and the second dust collecting duct 2632 is connected to the dust collecting fan 264 and the noise reduction housing 262 . When the dust outlet 169 of the self-moving cleaning device 100 is connected to the dust collecting port 2115 of the base station 200, the dust collecting airflow generated by the dust collecting fan 264, as shown in FIG. 3, FIG. 9 and FIG. 13, flows from the dust box 160 of the self-moving cleaning device 100, the dust discharge channel 168, the dust outlet 169, the dust collecting port 2115, and flows into the dust bag 216 in the dust bag bin 215 through the first dust collecting pipe 2631. The dust collecting airflow brings the garbage in the dust box 160 into the dust bag 216. The dust collecting device 261 collects and intercepts the garbage, and the dust collecting airflow flows from the dust bag bin 215 through the dust collecting fan 264 and the second dust collecting pipe 2632 into the noise reduction shell 262, and is discharged into the base station shell 210 through the exhaust port 2621 of the noise reduction shell 262. The noise reduction shell 262 is used to reduce the noise of the airflow passing through it, so as to reduce the working noise of the dust collecting fan 264 and improve the comfort of the user.

In some possible embodiments provided by the present disclosure, a first sound absorbing member is disposed in the noise reduction housing 262. The first sound absorbing member may be a member made of sound absorbing cotton or other sound absorbing materials. By disposing the first sound absorbing member in the noise reduction housing 262, the dust collecting airflow flowing through 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.

It can be understood that the dust collecting assembly 260 provided by the present disclosure, by adding a noise reduction shell 262 at the end of the dust collecting air duct, makes the dust collecting airflow not be discharged directly by the dust collecting fan as in the embodiments of the related art, but discharged by the noise reduction shell 262 connected to the dust collecting fan 264, so that the dust collecting airflow continues to flow in the noise reduction shell 262 before being discharged. Therefore, the first sound absorbing member provided in the noise reduction shell 262 can be used to achieve the purpose of noise reduction, so as to further ensure a good noise reduction effect and reduce the working noise of the dust collecting fan 264.

In some possible implementations provided by the present disclosure, as shown in FIG12 and FIG19, an air outlet 2119 is further provided on the base station housing 210, and the exhaust port 2621 is not opposite to the air outlet 2119. In other words, after the dust-collected airflow is discharged from the exhaust port 2621 of the noise reduction housing 262, it will flow into the interior of the base station housing 210, and be discharged to the external environment through the air outlet 2119 provided on the base station housing 210. Because the exhaust port 2621 is not opposite to the air outlet 2119, the transmission channel of the dust-collecting airflow between the exhaust port 2621 and the air outlet 2119 is a bent channel, that is, the working noise of the dust-collecting fan 264 needs to pass through the bent transmission channel between the exhaust port 2621 and the air outlet 2119 to be discharged from the air outlet. Since the bent transmission channel blocks the outward transmission of sound and can enhance the friction and dissipation of sound waves, the dust-collecting airflow once again achieves the purpose of noise reduction in the process of being discharged from the exhaust port 2621 and the air outlet 2119 to the external environment, reducing the impact of noise on users, thereby helping to improve the comfort of users.

In the above embodiment, as shown in FIG12, the base station housing 210 includes four body side walls connected in sequence to form a frame structure. Furthermore, the accommodating cavity 211 on the base station 200 for accommodating the self-moving cleaning device 100 can be located on one of the four body side walls located at the front of the base station 200, and the front of the base station 200 can be as shown in FIG7. Among them, the exhaust port 2621 is opposite to one of the body side walls, and the air outlet 2119 can be set on the other body side walls, thereby ensuring that the propagation channel of the dust-collected airflow between the exhaust port 2621 and the air outlet 2119 is a curved channel to ensure a good noise reduction effect.

The air outlet 2119 can be opened on one, two or three of the other three body side walls except the body side wall opposite to the exhaust port 2621. In some embodiments, the air outlet 2119 can also be opened on the body side wall opposite to the exhaust port 2621, and the air outlet 2119 and the exhaust port 2621 are not opposite, such as the air outlet 2119 is set far away from the exhaust port 2621.

As shown in FIG. 11 , in some possible embodiments provided by the present disclosure, a second sound absorbing member 2641 is provided on the dust collecting fan 264, and the second sound absorbing member 2641 is used to absorb the sound of the dust collecting airflow flowing through the air outlet of the dust collecting fan 264, thereby further reducing the aerodynamic noise of the dust collecting fan 264, reducing the working noise of the dust collecting fan 264, and improving the comfort of the user.

Furthermore, the second sound absorbing member 2641 is also configured to filter the dust collecting airflow flowing through the air outlet of the dust collecting fan 264. For example, the second sound absorbing member 2641 can be a sound absorbing filter cotton, so that the second sound absorbing member 2641 has a filtering function at the same time, that is, the second sound absorbing member 2641 simultaneously plays a role in reducing noise and filtering the dust collecting airflow again. Under the condition of greatly reducing the working noise of the dust collecting fan 264, the dust collecting airflow flowing out of the air outlet of the dust collecting fan 264 can be filtered, thereby improving the cleanliness of the airflow discharged to the external environment.

Furthermore, the dust collecting fan 264 generates impurities such as carbon powder during operation, and the impurities can also be filtered by the second sound absorbing member 2641. In other words, the second sound absorbing member 2641 can not only filter the dust collecting airflow from the dust box 160, but also filter the impurities such as carbon powder generated by the dust collecting fan 264, thereby further improving the cleanliness of the airflow discharged to the external environment and reducing the pollution to the environment.

As shown in FIG. 10 and FIG. 11 , in the above embodiment, the dust collecting fan 264 is a vortex fan, wherein the vortex fan has a small volume, high pressure, and high wind speed, which can meet the design requirements of the small volume of the base station 200, and at the same time can ensure a high dust collecting efficiency and a good dust collecting effect.

The vortex fan is provided with a vortex cavity 2642 and a transition cavity 2643 connected through an air port 2644, an air inlet port is provided on the cavity wall of the vortex cavity 2642, an air outlet port is provided on the cavity wall of the transition cavity 2643, and a second sound absorbing member 2641 is located in the vortex cavity 2642. Thus, the second sound absorbing member 2641 can absorb and filter the dust-collecting airflow flowing from the vortex cavity 2642 to the transition cavity 2643, as shown in FIG11.

As shown in FIG9, FIG13, and FIG14, in some possible embodiments provided by the present disclosure, the dust bag bin 215 is provided with an airflow inlet 2151 and an airflow outlet 2152, the dust collection device 261 is connected to the airflow inlet 2151, the air inlet port of the dust collecting fan 264 is connected to the airflow outlet 2152, and the air outlet port of the dust collecting fan 264 is connected to the noise reduction shell 262 through the second dust collecting duct 2632. In other words, the dust collecting fan 264 is located between the dust bag bin 215 and the noise reduction shell 262, and is connected to the noise reduction shell 262 through the second dust collecting duct 2632. It should be noted that the air flow inlet 2151 of the dust bag bin 215 is connected to the dust collecting port 2115 of the base station through the first dust collecting pipe 2631 , and the dust box 160 of the self-moving cleaning device 100 is also provided with an air inlet 163 and a dust inlet 166 . When the dust outlet 169 of the self-moving cleaning device 100 is connected to the dust collecting port 2115 of the base station 200, the dust collecting airflow generated by the dust collecting fan 264 can make the garbage in the dust box 160 of the self-moving cleaning device 100 flow along with the dust collecting airflow, and the dust will flow through the dust collecting port 2115 of the dust collecting port 2151 of the dust bag bin 215 through the dust outlet 169 of the self-moving cleaning device 100, the dust collecting port 2115 on the base station 200, the first dust collecting pipe 2631, and the airflow inlet 2151 of the dust bag bin 215. Device 261, after the garbage is collected and intercepted by the dust collection device 261, the dust collection airflow flows into the dust collection fan 264 from the air flow outlet 2152 of the dust bag bin 215, and then flows into the noise reduction housing 262 through the second dust collection duct 2632 from the air outlet of the dust collection fan 264, and is discharged to the inside of the base station housing 210 through the exhaust port 2621 of the noise reduction housing 262, and is discharged to the external environment through the air outlet 2119 on the base station housing 210, realizing the whole cycle.

Among them, a sealing part is also provided around the dust collecting port 2115 of the base station 200. When the dust outlet 169 of the self-moving cleaning device 100 is connected with the dust collecting port 2115, the setting of the sealing part can seal the gap between the dust outlet 169 and the dust collecting port 2115, and can avoid the problem that the dust collecting air duct cannot form a negative pressure due to air leakage between the dust outlet 169 and the dust collecting port 2115, resulting in the inability to achieve dust collection. At the same time, it can avoid the situation that the dust outlet 169 and the dust collecting port 2115 leak out due to air leakage, thereby ensuring that the dust collecting operation can be carried out smoothly and is conducive to ensuring a good dust collecting effect. Specifically, the sealing portion may be an elastic member.

It can be understood that, as shown in FIG8 , a decorative opening 21151 is further provided in the receiving chamber 211 of the base station 200. For example, the decorative opening 21151 is opened on the side wall of the receiving chamber 211. The decorative opening 21151 and the dust collecting opening 2115 are distributed on both sides of the center line of the base station 200 parallel to the vertical direction. For example, the decorative opening 21151 and the dust collecting opening 2115 are distributed on the left and right sides of the receiving chamber 211. An elastic portion can also be provided around the decorative opening 21151. In this way, When the self-moving cleaning device 100 is docked on the base station 200, after the dust outlet 169 is docked with the dust collection port 2115, the other parts of the self-moving cleaning device 100 will abut against the elastic part around the decorative port 21151, thereby ensuring that the self-moving cleaning device 100 is reliably docked on the base station 200 and avoiding the possibility of the self-moving cleaning device 100 shaking during the dust collection process. At the same time, the setting of the decorative port 21151 can ensure the neatness and aesthetics of the appearance of the base station 200.

As shown in FIG. 13 , in the above embodiment, a first filter 2153 is disposed in the dust bag bin 215, and the first filter 2153 is located at the airflow outlet 2152. The first filter 2153 can filter the dust collecting airflow flowing from the airflow outlet 2152 of the dust bag bin 215 into the dust collecting fan 264, thereby improving the cleanliness of the airflow flowing into the dust collecting fan 264, which is beneficial to improving the service life of the dust collecting fan 264 and improving the reliability of the dust collecting assembly 260.

Specifically, the first filter 2153 can be a filter mesh, filter cotton or other filter components, and the first filter 2153 can be fixed at the outlet 2152 of the dust bag bin 215 by at least one of a snap-fit structure, a mortise and tenon structure, an adhesive, and a screw structure.

In order to improve space utilization and the volume of dust bags, dust bags are usually designed and manufactured to be as large as or slightly smaller than the size of the dust bag bin. However, during dust collection, the dust bag bottom may be attracted to the airflow outlet of the dust bag bin due to the suction of the dust collection fan, causing blockage. During long-term use, the dust bag that was not originally in contact with the airflow outlet may be stretched due to the gravity of the dust and the suction of the dust collection fan, so that its bottom covers the airflow outlet and causes blockage. To this end, as shown in FIG. 13 , in some possible embodiments provided by the present disclosure, a plurality of supporting parts 2154 are provided in the dust bag bin 215, and the plurality of supporting parts 2154 are spaced and distributed around the airflow outlet 2152, and are used to support at least part of the dust collecting device 261. The arrangement of the supporting parts 2154 prevents the dust collecting device 261 from completely covering the airflow outlet 2152, thereby facilitating the flow of the dust collecting airflow, preventing blockage, and improving the dust collecting efficiency.

As shown in Figures 7, 8, 13, 14, 19 and 20, in some possible embodiments provided by the present disclosure, the base station 200 further includes: a dust bag compartment cover 2156, and the opening of the dust bag compartment 215 on the base station shell 210 faces forward, wherein the front and rear directions of the base station 200 are as shown in Figure 7, that is, the opening of the dust bag compartment 215 is located at the front of the base station 200. The dust bag compartment cover 2156 is detachably connected to the base station housing 210 to cover or open the opening of the dust bag compartment 215. It can be understood that when the dust bag compartment cover 2156 covers the opening of the dust bag compartment 215, it can also seal the opening of the dust bag compartment 215, so that the dust bag compartment 215 is a closed cavity to ensure that the dust collection air duct can generate negative pressure and ensure that the dust collection operation can be performed reliably.

In this embodiment, the dust bag bin cover 2156 can be conveniently opened or closed. 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, so that the user can disassemble and replace the dust collection device 261 through the opening of the dust bag bin 215, which is convenient to use. When the dust collection operation needs to be performed, the dust bag bin cover 2156 is buckled at the opening of the dust bag bin 215 to seal the dust bag bin 215, so that the dust bag bin 215 constitutes a part of the dust collection air duct.

Among them, the dust bag cover 2156 can be detachably connected to the base station housing 210 through at least one of a snap-on structure, a mortise and tenon structure, a magnetic structure, and a screw structure.

In the above embodiment, the dust bag cover 2156 is detachably connected to the base station housing 210 through a snap-on assembly. Since the snap-on assembly has a simple structure and low cost, compared with the base station in the related art that has a pull-out drawer to place the dust bag, the structure of the base station 200 is simplified, which is conducive to reducing the manufacturing cost of the base station 200. At the same time, compared with the dust bag cover and the base station housing connected by a magnetic suction assembly in the related art, it also has the advantage of low cost.

As shown in Figures 18 and 20, in some possible embodiments provided by the present disclosure, the card assembly connecting the dust bag compartment cover 2156 and the base station housing 210 includes a first card connector 2157 and a second card connector 2158 that match each other. The first card connector 2157 is located on the dust bag compartment cover 2156, and the second card connector 2158 is located on the base station housing 210. Thus, by using the first card connector 2157 and the second card connector 2158 to cooperate with each other, the dust bag compartment cover 2156 can be connected to the base station housing 210 to close the opening of the dust bag compartment 215, or the dust bag compartment cover 2156 can be removed from the base station housing 210.

Among them, the first clamping member 2157 is detachably connected to the dust bag compartment cover 2156, and the first clamping member 2157 and the dust bag compartment cover 2156 can be disassembled and separated for maintenance respectively, which is conducive to reducing maintenance costs. It is understandable that in other embodiments, the first clamping member 2157 and the second clamping member 2158 can be interchanged, such as the first clamping member is located on the base station housing 210, and the second clamping member is located on the dust bag compartment cover. This disclosure takes the first clamping member 2157 located on the dust bag compartment cover 2156 and the second clamping member 2158 located on the base station housing 210 as an example for explanation.

Furthermore, since the first clamping member 2157 and the second clamping member 2158 will be in contact and worn during the disassembly and assembly process of the dust bag cover 2156 and the base station housing 210, the first clamping member 2157 can be detachably connected to the dust bag cover 2156, and the first clamping member 2157 that is worn or damaged can be replaced, which is convenient to operate. Compared with the related art in which the first clamping member and the dust bag cover are integrally formed, when the first clamping member is worn or damaged, the entire dust bag cover needs to be replaced, which reduces the maintenance cost.

As shown in Figures 13 and 18, in a specific example, the second clip 2158 and the base station housing 210 are an integrated structure, which simplifies the operation of assembling the second clip 2158 and the base station housing 210, which is beneficial to improving the assembly efficiency. At the same time, it is beneficial to improve the reliability of the connection between the second clip 2158 and the base station housing 210, thereby improving the overall reliability of the base station 200. It is understandable that, under the same conditions, the wear rate of the second clamping member 2158 can be lower than the wear rate of the first clamping member 2157, that is, the second clamping member 2158 with a lower wear rate in the clamping assembly is integrated on the base station housing 210, and the first clamping member 2157 with a higher wear rate is detachably connected to the dust bag cover 2156, so that the first clamping member 2157 can be easily changed to extend the service life of the clamping assembly.

In another specific example (not shown in the figure), the second clip is detachably connected to the base station housing 210. In this way, the second clip and the base station housing 210 can be disassembled and separated and then repaired and replaced separately, which is conducive to reducing maintenance costs.

As shown in Figures 19 and 20, in some possible embodiments provided by the present disclosure, the dust bag bin cover 2156 is a U-shaped structure, the dust bag bin cover 2156 includes a front plate 21561 and side plates 21562 located on both sides of the front plate 21561, the first clamping piece 2157 is located on the side plate 21562, the base station housing 210 includes two bag cavity side walls 21551 located on both sides of the opening of the dust bag bin 215 along a first direction, and the first direction can be the left and right direction of the base station 200, as shown by the arrow X in Figure 8, and the second clamping piece 2158 is located on the bag cavity side wall 21551 and outside the dust bag bin 215. Thus, by buckling the dust bag compartment cover 2156 on the outer sides of the two bag cavity side walls 21551 of the base station housing 210, the first clamping piece 2157 and the second clamping piece 2158 cooperate with each other, and the front plate 21561 can be used to cover and seal the opening of the dust bag compartment 215. The structure is simple and can meet the design requirements of the base station 200 with a compact structure and a small volume, and the cost of this structure is low.

As shown in Figures 21 and 22, in some possible embodiments provided by the present disclosure, the first clip 2157 includes a first connecting portion 21571 and a clip 21572 connected to each other, and the first connecting portion 21571 is connected to the side plate 21562. Thus, the entire first clip 2157 can be installed on the dust bag bin cover 2156 by connecting the first connecting portion 21571 to the side plate 21562. The first connecting part 21571 and the side plate 21562 can be connected by screws. For example, a through hole is provided on the first connecting part 21571, and a threaded hole is provided on the side plate 21562. The screw passes through the through hole and connects with the threaded hole on the side plate 21562, so that the first connecting part 21571 can be fixed on the dust bag bin cover 2156.

As shown in FIG. 13 and FIG. 18 , the second clamping member 2158 is a clamping slot provided on the side wall 21551 of the bag cavity, and the clamping portion 21572 can be accommodated in the clamping slot and detached from the clamping slot. Thus, when the clamping portion 21572 is accommodated in the clamping slot, the dust bag compartment cover 2156 can be connected to the base station housing 210 to cover and seal the opening of the dust bag compartment 215. When the clamping portion 21572 is detached from the clamping slot, the dust bag compartment cover 2156 can be separated from the base station housing 210 to open the opening of the dust bag compartment 215, so as to facilitate the replacement of the dust collection device 261.

Among them, at least the clamping part 21572 of the first clamping part 2157 is set as an elastic part. Setting the clamping part 21572 as an elastic part can ensure that the clamping part 21572 is smoothly and reliably accommodated in the clamping slot or detached from the clamping slot, so as to ensure that the first clamping part 2157 and the second clamping part 2158 are smoothly clamped or separated. It can be understood that the first connecting part 21571 of the first clamping part 2157 can also be set as an elastic part, such as the entire first clamping part 2157 is set as an elastic part, which is convenient for processing.

As shown in FIG. 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 clamping 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 clamping member 2157 is connected to the bin cover body 21567, and the decorative cover 21568 can be used to cover the first clamping member 2157, thereby ensuring the aesthetic appearance of the dust bag bin cover 2156.

By setting an avoidance hole 21563 at a position opposite to the bag cover body 21567 and the clamping part 21572, at least a portion of the clamping part 21572 can be exposed inside the dust bag cover 2156 by utilizing the avoidance hole 21563, so that the dust bag cover 2156 can be clamped with the second clamping part 2158 from the outside of the two bag cover side panels 21562 of the base station 200, so as to connect the dust bag cover 2156 to the base station shell 210 and seal the dust bag cover 215. At the same time, with this arrangement, the decorative cover 21568 opposite to the avoidance hole 21563 can block and limit the clamping portion 21572, thereby improving the reliability and stability of the clamping portion 21572 being accommodated in the clamping slot, and improving the reliability of the clamping of the dust bag cover 2156 and the base station housing 210.

Among them, the decorative cover 21568 and the warehouse cover body 21567 can be detachably connected through at least one of a screw structure, a clamping structure, a mortise and tenon structure, and a hot melt adhesive, so as to facilitate the removal of the decorative cover 21568 and the warehouse cover body 21567 and replace the first clamping member 2157.

As shown in Figures 18 and 20, in some possible embodiments provided by the present disclosure, a positioning portion 21565 is provided on a side of the cover body 21567 away from the decorative cover 21568, and a limiting portion 21552 is also provided on the base station shell 210. The limiting portion 21552 and the positioning portion 21565 are adapted to limit the movement of the dust bag cover 2156 relative to the base station shell 210. Therefore, the dust bag cover 2156 and the base station housing 210 can be pre-positioned by using the positioning part 21565 and the limiting part 21552, which is conducive to improving the accuracy of the first clamping part 2157 and the second clamping part 2158, thereby improving the assembly efficiency of the dust bag cover 2156 and the base station housing 210. Among them, the positioning part 21565 and the limiting part 21552 can be matching grooves and protrusions, such as the positioning part 21565 is a positioning protrusion provided on the cover body 21567, and the limiting part 21552 is a limiting groove provided on the bag cavity side wall 21551 of the base station housing 210.

In some possible implementations provided by the present disclosure, a sealing structure is provided on one side of the bin cover body 21567 away from the decorative cover 21568, which is used to seal the gap between the bin cover body 21567 and the base station housing 210 when the dust bag bin cover 2156 covers the opening of the dust bag bin 215. The provision of the sealing structure can improve the sealing of the connection between the dust bag bin cover 2156 and the base station housing 210, thereby ensuring that the dust bag bin 215 is a closed cavity and the reliability of the dust collection operation. Specifically, the sealing structure can be a sealing ring, a sealing surface or other sealing structure, which is not specifically limited in the present disclosure. The sealing structure can be installed on the warehouse cover body 21567 by at least one of an adhesive, a snap-fit structure, a mortise and tenon structure, and a screw structure.

As shown in Figures 21 and 22, in some possible embodiments provided by the present disclosure, the number of the clamping parts 21572 is one or at least two. The number of the clamping parts 21572 can be reasonably set according to the specific structure and size of the clamping parts 21572 to ensure the reliability and stability of the clamping of the first clamping member 2157 and the second clamping member 2158. Among them, at least two clamping parts 21572 are spaced apart, so that it can be ensured that after one clamping part 21572 is damaged and deformed, it will not cause the adjacent clamping part 21572 to deform. By using the undeformed clamping part 21572 to clamp with the second clamping part 2158, the reliability of the connection between the first clamping part 2157 and the second clamping part 2158 can still be ensured, thereby extending the service life of the first clamping part 2157.

As shown in FIG. 21 , in the above embodiment, the avoidance holes 21563 correspond to the clamping parts 21572 one by one, and the warehouse cover body 21567 is provided with a rib 21564 between two adjacent avoidance holes 21563. The provision of the rib 21564 plays a good protective role for the two adjacent clamping parts 21572, and can reduce the influence of the deformed clamping part 21572 on the adjacent clamping part 21572, which is conducive to extending the overall service life of the first clamping part 2157, thereby improving the reliability of the first clamping part 2157.

In a specific example, the card slot corresponds to the card connection portion 21572 one by one, which is conducive to improving the reliability of the card connection between the first card connection portion 21572 and the second card connection portion 21572, thereby improving the reliability of the card connection between the dust bag compartment cover 2156 and the base station housing 210.

As shown in FIG. 18 , in another specific example, all the card-connecting parts 21572 correspond to one card slot, which facilitates the processing of the card slot and helps reduce the manufacturing cost of the base station housing 210 .

As shown in FIG. 13, FIG. 14, and FIG. 15, in some possible embodiments provided by the present disclosure, the base station 200 further includes a dust bag bracket 270 disposed in the dust bag bin 215, the dust bag bracket 270 is configured to install the dust collection device 261, and the dust bag bracket 270 is provided with a guide groove 271, and the guide groove 271 is configured to guide the dust collection device 261 to connect or separate from the dust bag bracket 270. In other words, through the guidance of the guide groove 271 on the dust bag bracket 270, the dust collection device 261 and the dust bag bracket 270 can be quickly and conveniently disassembled and assembled, thereby facilitating the processing of the garbage collected by the base station 200, and the operation is convenient.

By providing an anti-pinch structure 2711 on the groove wall of the guide groove 271, the possibility of the dust collecting device 261 being stuck or pinched in the guide groove 271 can be reduced. The provision of the anti-pinch structure 271 enables the dust collecting device 261 to be smoothly and completely opened. The dust collecting device 261 has a larger volume and avoids the problem of the dust collecting device 261 being stuck in the guide groove 271 and affecting the circulation of the dust collecting airflow, which is beneficial to improving the dust collection effect of the base station 200. It should be noted that the dust collecting device 261 includes a dust bag body, which is made of a breathable material that can filter small particles, such as non-woven fabrics or paper materials, and is configured to receive garbage. The dust collecting device 261 mentioned in this disclosure is stuck on the groove wall of the guide groove 271, which means that the dust bag body is stuck on the side wall of the guide groove 271.

As shown in FIGS. 13, 14 and 15, the opening of the guide groove 271 is in the same direction as the opening of the dust bag compartment 215. Thus, when the dust bag compartment cover 2156 opens the opening of the dust bag compartment 215, the dust collecting device 261 can be installed on the dust bag bracket 270 through the guide groove 271 through the opening of the dust bag compartment 215, or can be removed from the dust bag bracket 270 through the guide groove 271. The opening of the bin 215 faces the front of the base station 200, and the opening of the guide groove 271 also faces the front of the base station 200. Therefore, the user can smoothly install the dust collection device 261 on the dust bag bracket 270 or remove it from the dust bag bracket 270 through the guide groove 271 from the front of the base station 200. In the dust bag bin 215, the user's hand does not need to change direction, so it is ergonomic and easy to operate.

As shown in FIG15 , in some possible embodiments provided by the present disclosure, the guide groove 271 is inclined relative to the vertical direction, and the vertical direction is such as the direction from the top to the bottom of the base station 200, such as the length direction of the guide groove 271 is inclined relative to the vertical direction, wherein the length direction of the guide groove 271 is as shown by the arrow L in FIG15 , thereby, when the dust collecting device 261 is installed on the dust bag bracket 270, the dust bag body of the dust collecting device 261 will droop downward under the action of gravity. Furthermore, the dust bag support 270 can be located at the top of the dust bag bin 215, wherein the top of the dust bag bin 215 is shown by the arrow in FIG. 15, such as the dust bag support 270 is located at a corner of the top of the dust bag bin 215.

Among them, since the dust bag body is made of soft material, when the dust collecting device 261 is installed on the dust bag bracket 270, the dust bag body will sag due to the effect of gravity, so the dust bag body will be clamped by the groove wall located below the guide groove 271, thereby affecting the dust bag body to be stretched out in the subsequent dust collection process. It should be noted that after the dust bag 216 is installed on the dust bag bracket 270, when the dust collecting fan 264 is working, the dust bag body will be stretched out under the action of the dust collecting airflow. Moreover, under normal circumstances, the dust collecting device 261 is inserted into the front opening of the guide groove 271 for installation. The front end of the guide groove 271 can be understood as the side of the guide groove 271 opposite to the opening of the dust bag bin 215. For this purpose, a notch structure is provided on the front end surface of the groove wall of the guide groove 271 located below, that is, the notch structure is opposite to the opening of the dust bag bin 215 and is provided on the groove wall of the guide groove 271 located below. The notch structure is used to avoid the dust bag body, which can avoid the situation where part of the dust bag body is stuck in the guide groove 271 under the action of gravity, which is conducive to the dust bag body being smoothly and completely opened in the subsequent dust collection process.

The notch structure can be a triangular notch, an arc notch, or a notch of other shapes that meet the requirements. Furthermore, the edge of the notch structure can be provided with a transition surface to play a guiding role, such as a smooth curved surface or a slope to ensure that the dust bag body can fall smoothly under the action of gravity and will not be stuck on the groove wall of the guide groove 271.

As shown in FIG. 16 and FIG. 17 , in some possible embodiments provided by the present disclosure, a hollow cavity is provided inside the dust bag support 270, and the hollow cavity includes a dust outlet interface 2712 located on the support side wall of the dust bag support 270 facing the dust bag bin 215, and the dust outlet interface 2712 is configured to dock with the inlet of the dust collection device 261. The hollow cavity also includes a dust inlet interface 2713 located on the support side wall of the dust bag support 270 facing the outside of the dust bag bin 215, and the dust bag bin 215 is provided with an airflow inlet 2151, and the dust inlet interface 2713 is configured to dock with the airflow inlet 2151 of the dust bag bin 215.

That is, the hollow cavity of the dust bag holder 270 can be used as a part of the dust collection duct of the base station 200. The dust collection assembly 260 of the base station 200 works so that the dust collection air flows through the dust box 160 of the self-moving cleaning device 100 into the base station 200, and flows into the dust collection device 261 through the air flow inlet 2151 of the dust bag bin 215 and the hollow cavity of the dust bag holder 270, and the garbage is collected and intercepted in the dust collection device 261.

As shown in FIG17 , the notch structure is located at the connection position between the groove wall and the dust outlet interface 2712. Since the dust bag body is usually stuck at the connection position between the groove wall of the guide groove 271 and the dust outlet interface 2712, the notch structure is provided at this position to reduce the occurrence of the dust bag body being stuck. At the same time, the dust bag body usually sags under the action of gravity and is stuck at the bottom portion of the dust outlet interface 2712. Therefore, by distributing the notch structure at least at the front bottom of the dust outlet interface 2712, the occurrence of the dust bag body being stuck can be greatly reduced.

Specifically, a notch structure can be provided at the connection position between the front bottom of the dust outlet interface 2712 and the groove wall below the guide groove 271, or, as shown in FIG15, a notch structure can be provided at the connection position between the front bottom of the dust outlet interface 2712 and the groove wall below the guide groove 271, and at the connection position between the front top and the groove wall below the guide groove 271. The top and bottom directions in FIG15 are the top and bottom directions of the base station.

As shown in FIG. 14 and FIG. 16 , in the above embodiment, the base station 200 further includes: a sealing member 273 disposed between the bag cavity side wall 21551 of the dust bag chamber 215 and the bracket side wall where the dust inlet interface 2713 is located. The seal 273 is used to seal the gap between the bag cavity side wall 21551 and the bracket side wall, thereby improving the sealing of the connection between the bag cavity side wall 21551 of the dust bag bin 215 and the bracket side wall of the dust bag bracket 270, avoiding the problem that the negative pressure cannot be formed in the dust collection duct due to air leakage between the bag cavity side wall 21551 and the bracket side wall of the dust bag bracket 270, resulting in the inability to achieve dust collection. At the same time, it can avoid the problem of garbage leaking from the gap between the bag cavity side wall 21551 and the bracket side wall, thereby ensuring that the dust collection operation can be carried out smoothly and is conducive to ensuring a good dust collection effect.

The seal 273 can be a sealing cotton, a sealing ring, a sealing strip or other sealing structures. Specifically, the seal 273 can be a sealing foam, and the seal 273 can be fixed on the side wall of the bracket by bolts and/or positioning columns, and then the dust bag bracket 270 is connected to the bag cavity side wall 21551 to use the seal 273 to seal the gap between the bracket side wall and the bag cavity side wall 21551.

As shown in FIG. 17 , in some possible embodiments provided by the present disclosure, the dust bag support 270 includes a sliding baffle 272 that can slide along the guide groove 271. The sliding baffle 272 is configured to switch between a first position and a second position. In response to the sliding baffle 272 being in the first position, the sliding baffle 272 shields the dust outlet interface 2712. In response to the sliding baffle 272 being in the second position, the sliding baffle 272 exposes the dust outlet interface 2712. Since the dust collecting device 261 is a consumable, it can be detachably mounted on the dust bag support 270. The dust bag holder 270 adopts the above design. When the dust bag holder 270 is not installed with the dust collecting device 261, the sliding baffle 272 shields the dust outlet interface 2712, isolates the dust bag bin 215 and the dust collecting air duct, so that the suction force generated by the dust collecting fan 264 cannot enter the dust bag bin 215, and prevents garbage from entering the dust bag bin 215 without the dust collecting device 261. It should be noted that, as shown in FIG16, the dust bag holder 270 further includes an elastic portion 274 connected to the sliding baffle 272, which is configured to make the sliding baffle 272 have a tendency to be in the first position. When the sliding baffle 272 is not acted upon by external force, under the action of the elastic part 274, the sliding baffle 272 is in the first position, so that the sliding baffle 272 shields the dust outlet interface 2712.

It can be understood that the dust bag 216 is configured to be able to slide along the extension direction of the guide groove 271. When the dust collecting device 261 is inserted into the guide groove 271 and slides along the guide groove 271 toward the inside of the dust bag bin 215, the sliding baffle 272 is pushed to slide along the extension direction of the guide groove 271 so that the dust collecting device 261 is installed on the dust bag bracket 270, and the sliding baffle 272 exposes the dust outlet interface 2712, so that the opening of the dust bag 216 is connected to the dust outlet interface 2712. After the dust bag 216 is installed on the dust bag bracket 270, the dust bag can be pulled out of the dust bag bin 215 so that the dust bag 216 slides along the guide groove 271 and detaches from the guide groove 271 to realize the removal of the dust bag 216 from the dust bag bracket 270. At the same time, the sliding baffle 272 can be reset to the initial position under the action of the elastic part 274 to shield the dust outlet interface 2712.

As shown in FIG. 17 , in some possible embodiments provided by the present disclosure, a groove wall located below the guide groove 271 is provided with a hollow structure at a position far away from the anti-pinch structure 2711, that is, a groove wall located below the guide groove 271 is provided with a hollow structure located in the dust bag compartment 215 at a position far away from the opening of the dust bag compartment 215, and the hollow structure is configured to expose part of the sliding baffle 272, and the hollow structure can be an opening, and a guide structure 2714 located in the dust bag compartment 215 is provided on the bottom wall of the dust bag bracket 270, and the guide structure 2714 is located on one side of the hollow structure far away from the sliding baffle 272. The setting of the guide structure 2714 can prevent the dust collecting device 261 from being misplaced, stuck, or protruding through the hollow structure when inserted into the guide groove 271, so that the dust collecting device 261 can smoothly abut against the sliding baffle 272 on the dust bag bracket 270 under the guidance of the guide groove 271 and the guide structure 2714, so as to push the sliding baffle 272 to slide in the guide groove 271 to expose the dust interface 2712.

The guiding structure 2714 can be a guiding protrusion, and a guiding slope is provided on one side of the guiding protrusion facing the guiding groove 271. Under the guiding effect of the guiding slope, the dust collecting device 261 in the guiding groove 271 can slide smoothly in the guiding groove 271 and can accurately abut against the sliding baffle 272.

Among them, in a specific example, the dust box 160 of the self-moving cleaning device 100 provided in the present disclosure has a filter 161 detachably connected to the dust box 160. When the dust box 160 is removed from the machine body 110 of the self-moving cleaning device 100, the filter 161 can be removed from the dust box 160 to use the exhaust port to clean the garbage in the dust box 160, or to clean the dust box 160, etc.

In another specific example, the dust box 160 includes a top wall, a bottom wall, and a dust box side wall, and the garbage storage chamber 162 has an opening, such as the dust box side wall encloses a garbage storage chamber opening 1621, and the top wall of the dust box 160 is configured to be movably connected to the dust box side wall to open or close the garbage storage chamber opening 1621. When the dust box 160 is disassembled from the machine body 110 of the self-moving cleaning device 100, the top wall of the dust box 160 is used to open the garbage storage chamber opening 1621, and the dust box 160 can be cleaned, such as cleaning the dust box 160 or dumping the garbage in the dust box 160, or repairing the dust box 160. After the top wall of the dust box 160 closes the garbage storage chamber opening 1621, the dust box 160 is installed on the machine body 110 and the vacuuming operation can be performed.

As shown in FIG. 4 and FIG. 6 , the dust box 160 provided in the disclosed embodiment has a dust outlet 164 opened on the side wall of the garbage storage chamber 162, and the side wall of the garbage storage chamber 162 where the dust outlet 164 is located is inclined with respect to other side walls of the garbage storage chamber 162 in the circumferential direction, wherein the circumference of the garbage storage chamber 162 can be understood as the circumference of the garbage storage chamber opening 1621. That is, the dust outlet 164 is arranged on a side wall around the opening of the garbage storage chamber 162, and the side wall is inclined with other side walls around the opening of the garbage storage chamber 162, so that the plane where the dust outlet 164 is located is inclined with other side walls in the circumferential direction of the garbage storage chamber 162, thereby improving the smoothness of the air flow in the dust box 160 through the dust outlet 164 and improving the circulation efficiency of the air flow in the dust box 160.

As shown in FIG3 and FIG6, by providing a guide member 165 in the garbage storage chamber 162, the guide member 165 is used to guide the airflow flowing into the air inlet 163 to the dust outlet 164, such as using the guide member 165 to guide the dust collecting airflow flowing into the air inlet 163 to the dust outlet 164, thereby avoiding the problem that the garbage in the dust box 160 is gathered at the corner of the garbage storage chamber 162 and is not collected, which is conducive to improving the thoroughness of collecting the garbage in the dust box 160 to the base station 200 and improving the dust collection effect.

In the above embodiment, the guide member 165 is an arc-shaped structure. The arc-shaped guide member 165 has a good guiding effect on the airflow, which can further improve the smoothness of the airflow in the dust box 160 discharged through the dust outlet 164, improve the circulation efficiency of the dust-collecting airflow in the dust box 160, and at the same time, can reduce the occurrence of garbage gathering on the guide member 165, which is conducive to further improving the thoroughness of the garbage collection in the dust box 160 to the base station 200.

As shown in FIG. 3 and FIG. 6 , the windward surface 1651 of the guide member 165 is in a concave arc shape. The concave arc shape can increase the circulation space of the dust collecting airflow between the air inlet 163 and the dust outlet 164 to a certain extent, which is conducive to improving the smoothness of the dust collecting airflow in the dust box 160. At the same time, the concave arc-shaped windward surface 1651 can smoothly guide the dust collecting airflow flowing into the air inlet 163 to the dust outlet 164, and then guide the garbage in the dust box 160 to the dust outlet 164 along with the dust collecting airflow, which is conducive to improving the dust collection effect.

As shown in FIG3 and FIG6 , in some possible embodiments provided by the present disclosure, the first end of the guide member 165 is connected to the side wall of the garbage storage chamber 162 at the dust outlet 164, and the second end of the guide member 165 extends toward the air inlet 163 and is connected to the side wall of the garbage storage chamber 162. In other words, the guide member 165 also acts as a baffle, and the guide member 165 can be used to divide the internal space of the dust box 160 into two chambers isolated from each other, and the air inlet 163 and the dust outlet 164 are located in the chamber where the windward surface 1651 of the guide member 165 is located, or, in some examples, the dust box 160 can be set to an irregular shape, and one side wall of the dust box 160 is set as the guide member 165. Thus, the guide member 165 can smoothly guide the dust collecting airflow flowing into the air inlet 163 to the dust outlet 164, avoiding the problem that the dust collecting airflow flowing into the chamber or position where the leeward side 1652 of the guide member 165 is located cannot be smoothly discharged through the dust outlet 164, resulting in the accumulation of garbage and inconvenience in collection, which greatly improves the thoroughness of collecting garbage in the dust box 160 to the base station 200.

At the same time, since the windward surface 1651 of the guide member 165 is a concave arc, the angles at the connection positions between the two ends of the guide member 165 and the side walls of the garbage storage chamber 162 are larger, which will reduce or avoid the phenomenon of garbage accumulation.

As shown in FIG. 4, FIG. 5 and FIG. 6, in some possible embodiments provided by the present disclosure, the side wall of the garbage storage chamber 162 includes a first dust box side wall 1611, a second dust box side wall 1612, a third dust box side wall 1613, a fourth dust box side wall 1614 and a fifth dust box side wall 1615 which are connected in sequence, the first dust box side wall 1611 and the third dust box side wall 1613 are arranged opposite to each other, the second dust box side wall 1612 and the fifth dust box side wall 1615 are arranged opposite to each other, the fourth dust box side wall 1614 is connected between the third dust box side wall 1613 and the fifth dust box side wall 1615 and is connected to the third dust box side wall 1614. 13 and the fifth dust box side wall 1615 are arranged obliquely, and the dust discharge port 164 is opened on the fourth dust box side wall 1614, thereby ensuring that the fourth dust box side wall 1614 where the dust discharge port 164 is located is in contact with 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 1614. The dust box side walls 1615 are all inclined, that is, the dust outlet 164 is inclined relative 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 conducive to the smoothness of the dust collected in the dust box 160 flowing through the dust outlet 164.

Among them, the inclination angle of the fourth dust box side wall 1614 and the third dust box side wall 1613 is greater than 90° and less than 180°, so that the inclination angle between the dust box 160 side wall of the garbage storage chamber 162 where the dust discharge port 164 is located and the dust box 160 side wall of the adjacent garbage storage chamber 162 is larger, which is convenient for the circulation of dust collection airflow and can reduce the accumulation of garbage at the connection position of the fourth dust box side wall 1614 and the third dust box side wall 1613 and the connection position of the fourth dust box side wall 1614 and the fifth dust box side wall 1615.

In the above embodiment, the air inlet 163 is opened on the second dust box side wall 1612, and the dust exhaust port 164 is opened on the fourth dust box side wall 1614, so that the dust collecting airflow flows smoothly. Among them, the dust inlet 166 is opened on the first dust box side wall 1611, and the air exhaust port is opened on the third dust box side wall 1613, so that the dust suction airflow flows smoothly.

As shown in FIG6 , one end of the guide member 165 is adjacent to one side of the dust outlet 164 and is arranged at approximately 90° to the plane where the dust outlet 164 is located, so that the dust-collected airflow is discharged from the dust outlet 164 at an approximately vertical angle under the guidance of the guide member 165 .

As shown in FIG. 3 , in some possible embodiments provided by the present disclosure, the machine body 110 of the self-moving cleaning device 100 is connected to the dust outlet 164 and the dust outlet 169 via a dust outlet channel 168, wherein the dust outlet channel 168 is arranged at approximately 90° to the plane where the dust outlet 164 is located, that is, the extension direction of the guide member 165 is approximately parallel to the extension direction of the dust outlet channel 168. As a result, the dust-collected air in the dust box 160 can flow smoothly into the dust discharge channel 168 through the guidance of the flow guide 165, thereby reducing the situation where the garbage in the dust box 160 is accumulated or blocked at the connection position between the dust discharge port 164 and the dust discharge channel 168, which is conducive to improving the thoroughness of collecting the garbage in the dust box 160 to the base station 200 and improving the dust collection effect.

As shown in FIG2 , the self-moving cleaning device 100 provided by the present disclosure, the wet cleaning system may include: a cleaning component, a water supply mechanism, a liquid storage tank, etc. Among them, the cleaning component may be arranged below the liquid storage tank, and the cleaning liquid inside the liquid storage tank is transmitted to the cleaning component through the water supply mechanism, so that the cleaning component performs wet cleaning on the surface to be cleaned. In other embodiments of the present disclosure, the cleaning liquid inside the liquid storage tank may also be directly sprayed onto the surface to be cleaned, and the cleaning component cleans the surface by evenly applying the cleaning liquid. It can be understood that the self-moving cleaning device 100 is provided with a water injection port connected to the liquid storage tank. The liquid outside the self-moving cleaning device 100 can be replenished into the liquid storage tank through the water injection port to realize the water replenishment operation of the liquid storage tank.

The cleaning assembly provided in the disclosed embodiment includes a motion mechanism and a cleaning element 183 disposed on the machine body 110, that is, the entire cleaning assembly can be installed on the machine body 110 through the motion mechanism, and the cleaning assembly moves with the movement of the machine body 110 to achieve the mopping function. Among them, the motion mechanism is used to drive the cleaning element 183 to move, such as the motion mechanism can drive the cleaning element 183 to rise and fall, and the motion mechanism can also drive the cleaning element 183 to rotate. Therefore, according to the requirement of whether the cleaning element 183 is in contact with the surface to be cleaned, the lifting and rotating operations of the cleaning element 183 can be realized through the motion mechanism to meet the different functional requirements of the cleaning element 183, that is, the processing of the distinguishing strategy of the cleaning element 183 can be realized, the cleaning performance of the self-cleaning device is improved, and the cleaning efficiency and use experience are improved.

As shown in FIG2 , in the forward direction of the self-propelled cleaning device 100, the cleaning element 183 is located at the rear of the dry cleaning system 151. The cleaning element 183 can generally be a flexible material with water absorption such as fabric or sponge. In this solution, the cleaning element 183 can be at least one rotating turntable. The water in the liquid storage tank of the self-propelled robot is guided to the cleaning element 183. The soaked cleaning element 183 removes the dirt on the ground through the rotating motion.

As shown in FIG. 23 and FIG. 24 , in some possible embodiments provided by the present disclosure, the base station 200 further includes a cleaning plate 220, which is disposed on the bottom wall of the receiving chamber 211. The cleaning plate 220 is used to interfere with the cleaning element 183 of the self-moving cleaning device 100 to remove dirt from the cleaning element 183. Thus, when the self-moving cleaning device 100 is docked in the receiving chamber 211 of the base station 200, the cleaning plate 220 can be used to clean the cleaning element 183, so that the dirty cleaning element 183 becomes a clean cleaning element 183 for the next mopping.

As shown in FIG. 23 , in some possible embodiments provided by the present disclosure, the cleaning plate 220 is detachably connected to the base station 200, so that the cleaning plate 220 can be removed from the base station 200 as a whole and cleaned, which is conducive to improving the thoroughness of the cleaning of the cleaning plate 220 and avoiding the possibility of the cleaning plate 220 being left on the cleaning plate 220 for a long time due to incomplete cleaning or inconvenient cleaning, thereby generating odor, which is conducive to improving the cleaning experience of the cleaning plate 220 and improving user satisfaction. At the same time, the cleaning plate 220 is detachably connected to the base station 200, which is conducive to improving maintenance efficiency.

As shown in FIG. 23 , the cleaning tray 220 includes a cleaning cavity 2211 and a cleaning portion 222 disposed inside the cleaning cavity 2211. The cleaning portion 222 is used to interfere with the cleaning element 183 of the self-moving cleaning device 100 to remove dirt on the cleaning element 183, thereby realizing a cleaning operation on the cleaning element 183. For example, when the cleaning element 183 is a tray, the cleaning operation on the tray is realized by the interference between the tray and the cleaning portion 222 in the cleaning cavity 2211. Since the cleaning cavity 2211 is used to accommodate dirt, the cleaning portion 222 can collect dirt on the cleaning element 183 after removing it and then gather it in the cleaning cavity 2211.

The cleaning plate 220 is configured to be detachably connected to the base station 200, so that the cleaning plate 220 can be detachably connected to the base station 200 as a whole, so that the user can install the cleaning plate 220 on the base station 200 or remove it from the base station 200 as needed. For example, the user can remove the entire cleaning plate 220 from the base station 200, which is convenient for cleaning the cleaning plate 220, improves the convenience of cleaning the cleaning plate 220, and can improve the thoroughness of cleaning the cleaning plate 220, and can avoid the accumulation of dirt or residue in the cleaning cavity 2211 for a long time to produce odor, which is conducive to improving user satisfaction.

As shown in FIG. 23 , in some possible embodiments provided by the present disclosure, a sewage tank 2212 located inside the cleaning chamber 2211 is provided on the bottom wall of the cleaning chamber 2211, and the bottom of the sewage tank 2212 may be lower than the upper surface of the bottom wall of the cleaning chamber 2211, so that after the cleaning part 222 removes the dirt on the cleaning element 183, the dirt will be gathered in the sewage tank 2212 under the action of gravity. Among them, the cleaning plate 220 further includes a sewage pipe 223, which is provided on the cleaning plate 220, and the first end of the sewage pipe 223 is connected to the sewage tank 2212, and the second end of the sewage pipe 223 extends to the outside of the cleaning chamber 2211. Thus, the sewage pipe 223 can be used to discharge the dirt in the sewage tank 2212, and then the dirt in the cleaning chamber 2211 can be discharged in time, so that the cleaning chamber 2211 can continue to contain the dirt, so as to achieve the continuous cleaning of the cleaning element 183, which is beneficial to improve the cleaning effect. At the same time, it can avoid the dirt in the cleaning chamber 2211 from overflowing due to failure to be discharged in time, which is beneficial to improve the user's satisfaction.

In the above embodiment, the base station 200 includes a sewage tank 214, and the second end of the sewage pipe 223 is connected to the sewage tank 214, so that the sewage can be collected in the sewage tank 214. It can be understood that a water pump can be provided on the pipeline connecting the sewage pipe 223 and the sewage tank 214 to realize the collection of sewage.

As shown in Figures 8 and 23, in some possible embodiments provided by the present disclosure, the cleaning plate 220 further includes: a water guide portion 224, which is arranged on the inner bottom wall of the cleaning cavity 2211 and protrudes from the surface of the cleaning cavity 2211, that is, the water guide portion 224 can be understood as a water guide rib, and a water guide groove 2241 is opened on the top of the water guide portion 224, and the water guide groove 2241 is connected to the water outlet 2112 on the base station 200. The water guide groove 2241 is used to contain cleaning liquid and can interfere with the cleaning element 183. Thus, the cleaning liquid flows from the water outlet 2112 of the base into the water guide groove 2241. When the cleaning element 183 interferes with the water guide groove 2241, it can use the cleaning liquid in the water guide groove 2241 to wet itself, and then the cleaning element 183 interferes with the cleaning part to achieve the cleaning of the cleaning element 183. Such a setting is conducive to improving the cleaning effect of the cleaning element 183. Among them, the water guide part 224 protrudes from the surface of the cleaning cavity 2211, so that the water guide groove 2241 on the water guide part 224 can reliably interfere with the cleaning element 183 to ensure that the water in the water guide groove 2241 can be smoothly dipped by the cleaning element 183.

As shown in FIG. 24 , a liquid leakage port 2242 connected to the water guide groove 2241 is provided on the water guide portion 224. After the cleaning liquid enters the water guide groove 2241 of the water guide portion 224, the cleaning element 183 of the self-moving cleaning device 100 cannot completely absorb the cleaning liquid in the water guide groove 2241, and residual cleaning liquid may remain in the water guide groove 2241. By providing a liquid leakage port 2242 connected to the water guide groove 2241 on the water guide portion 224, the residual cleaning liquid in the water guide groove 2241 can be discharged from the liquid leakage port 2242, thereby avoiding the situation in which the liquid remains in the water guide groove 2241 for a long time and generates an odor, thereby helping to improve the cleanliness of the water guide groove 2241. It is understandable that when the cleaning plate 220 is removed from the base station 200 for cleaning, the water guide portion 224 and the cleaning portion 222 may also be cleaned.

As shown in FIG7 and FIG8, the clean water tank 213 is located above the receiving chamber 211 for receiving cleaning liquid, and the water outlet 2112 is connected to the clean water tank 213, and the cleaning liquid in the clean water tank 213 can be input into the water guide groove 2241 through the water outlet 2112. The water outlet 2112 can be located at the top of the receiving chamber 211, and the water outlet 2112 is directly opposite to the water guide groove 2241 of the water guide part 224. In this way, the opening and closing of the water outlet 2112 can be controlled by a valve or other components, so that the cleaning liquid in the clean water tank 213 can be input into the water guide groove 2241 under the action of gravity. It is understandable that the water outlet 2112 can also be located on the side wall of the container cavity, and the water outlet 2112 and the water guide groove 2241 are connected through a pipeline to flow the cleaning liquid in the cleaning box into the water guide groove 2241.
