[0045] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of this application without making creative efforts are within the scope of protection of this application.

[0046] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0047] One aspect of the present application provides a cleaning system. In a specific embodiment, please refer to Figure 1, which is a cross-sectional view of an embodiment of the cleaning system provided by the present application. The cleaning system includes a cleaning device 100 and a dust collection station 200. The cleaning device 100 can be a sweeping robot, a mopping robot, a sweeping and mopping robot, etc., which is used to vacuum, sweep, or even wet mop the floor of a house. In addition, the cleaning device 100 can be separated from the dust collection station 200 to perform cleaning work independently and store dust, debris, and other garbage collected during the cleaning or vacuuming process. When the cleaning device 100 completes its work or the stored dust and debris reaches a preset capacity, the cleaning device 100 is docked with the dust collection station 200, and the dust collection station 200 collects the dust and debris stored in the cleaning device 100.

[0048] To ensure that the dust collection station 200 can uniformly process dust and debris, referring again to Figure 1 , in some embodiments, the dust collection station 200 includes a docking port 201, an internal fan 202, a dust chamber 203, and a channel 204. Channel 204 connects the docking port 201 and the dust chamber 203. The suction port 2021 of the internal fan 202 communicates with the dust chamber 203. The cleaning device 100 includes a main body 1 and a dust box 3. The dust box 3 is detachably mounted on the main body 1 and has a dust outlet 312.

[0049] When the cleaning device 100 is docked with the dust collection station 200, the docking port 201 communicates with the dust outlet 312. The station's internal fan 202 operates, sucking air from the area where the dust collection station 200 and the cleaning device 100 are docked. The suction force of the station's fan 202 causes the dust and dirt inside the dust box 3 to flow from the dust outlet 312 into the docking port 201, and then into the dust chamber 203 along the passage 204.

[0050] It can be understood that in some embodiments, a garbage bag (not shown) can be installed in the dust chamber 203 to completely store dust or garbage in the garbage bag. When the garbage in the dust chamber 203 needs to be processed, the cover of the dust chamber 203 (not shown) is opened and the installed garbage bag can be thrown away, thereby realizing quick garbage disposal.

[0051] Specifically, the main body 1 is provided with a dust collection channel 11. When the cleaning device 100 is docked with the dust collection station 200, the dust collection channel 11 connects the dust outlet 312 and the dust collection station 200. In some specific embodiments, the main body 1 is provided with at least one dust collection channel 11. Each dust collection channel 11 is provided with at least one dust inlet port 111 and at least one dust outlet port 112. The dust inlet port 111 is connected to the corresponding dust outlet 312, and the dust outlet port 112 is connected to the docking port 201. To improve dust collection efficiency, the number of dust outlets 312 can be multiple, and the number of dust collection channels 111 can be set to correspond to the number of dust outlets 312; alternatively, the number of dust inlet ports 111 of the dust collection channel 11 can be set to correspond to the number of dust outlets 312. Similarly, to facilitate docking connection between the cleaning device 100 and the dust collection station 200, the number of docking ports 201 is the same as the number of dust outlet ports 112. As needed, the docking port 201 and the dust outlet port 112 can be set to one or to a corresponding number. The specific structure will be described in detail later in conjunction with the specific structure of the main body 1 and the dust box 3.

[0052] Please refer to Figures 2 to 4. Figure 2 is a schematic structural diagram of an embodiment of the cleaning device described in Figure 1; Figure 3 is a top view of the cleaning device described in Figure 2; and Figure 4 is a bottom view of the cleaning device described in Figure 2. Specifically, the cleaning device 100 further includes a wheel assembly 4 connected to the main body 1, supported on the work surface, and movable on the work surface. The dust box 3, projected toward the work surface, is located within the projection of the main body 1. In other words, the dust box 3 can be positioned anywhere within the contour of the main body 1 according to actual design requirements, as long as the dust box 3, projected toward the work surface, is located within the projection of the main body 1. This facilitates design diversity for the entire cleaning device 100 and avoids the situation where the dust box 3 is placed externally to the main body 1 during the overall design of the cleaning device 100, which would result in the cleaning device 100 being excessively bulky, making it unable to fit into gaps between furniture and the floor, and creating blind spots during operation.

[0053] Among them, the running wheel assembly 4 includes a first running wheel 41 and a second running wheel 42, and the first running wheel 41 and the second running wheel 42 are both connected to the main body 1. The first running wheel 41 and the second running wheel 42 can be arranged at the bottom of the main body 1 to drive the main body 1 to move on the work surface. And along the forward direction of the cleaning device 100, that is, the X direction in Figure 3, the first running wheel 41 and the second running wheel 42 can be respectively located on the left and right sides of the dust box 3. It should be noted that the first running wheel 41 and the second running wheel 42 are respectively located on the left and right sides of the dust box 3, which can mean that the dust box 3 is staggered with the first running wheel 41 and the second running wheel 42 in the X direction, or it can mean that on the projection surface perpendicular to the left and right directions, the projection of the dust box 3 has an overlapping area with the projection of the first running wheel 41 and the second running wheel 42, which can be reasonably arranged according to the center of gravity of the cleaning device 100.

[0054] It is understood that in some embodiments, the cleaning device 100 further includes universal wheels 14 for supporting the main body 1 and assisting the movement of the first and second travel wheels 41, 42. These wheels are used to steer the cleaning device 100 when it needs to change direction, assisting in steering and maneuvering. The universal wheels 14 are located at the bottom of the main body 1. Optionally, the universal wheels 14 are located at the rear side of the dust box 3, along the direction of travel of the cleaning device 100.

[0055] Optionally, the main body 1 is provided with a mounting cavity 120, and the dust box 3 is removably disposed within the mounting cavity 120. To facilitate the removal of the dust box 3, the main body 1 specifically includes a mounting base 12, which is provided with a mounting cavity 120. The mounting cavity 120 is recessed from the top to the bottom of the mounting base 12, and the dust box 3 is removably mounted within the mounting cavity 120, making it easy to remove the dust box 3 and clean it separately. In addition, the dust box 3 can be removed and installed in the mounting cavity 120 in the vertical direction relative to the mounting base 12, that is, the dust box 3 supports upward removal and downward installation into the mounting cavity 120, which is more convenient for user operation. The first running wheel 41, the second running wheel 42, and the universal wheel 14 are all mounted on the bottom of the mounting base 12 facing away from the mounting cavity 120. Of course, in other embodiments, the opening direction of the mounting cavity 120 can also be left-right or front-back, and correspondingly, the dust box 3 can be removed and installed in the left-right or front-back direction relative to the mounting base 12, which is not a sole limitation here.

[0056] It is understood that the front direction in the front-to-back direction is the forward direction of the cleaning device 100, that is, the x-direction shown in Figure 3; the rear direction is the backward direction of the cleaning device 100, which is opposite to the forward direction; the left and right directions are the left and right directions of the cleaning device 100, respectively, both of which are perpendicular to the forward direction. It is understood that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative position relationship and movement of various components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indication will also change accordingly.

[0057] Furthermore, the cleaning device 100 also includes a cover 13, which is provided on the main body 1 and covers the mounting cavity 120, thereby accommodating the dust box 3 inside the mounting cavity 120 of the main body 1. On the one hand, the cover 13 cooperates with the main body 1 to position the dust box 3, preventing the dust box 3 from being shaken when the cleaning device 100 is working, causing the dust box 3 to separate from the mounting cavity 120, and then simultaneously separating from the suction assembly 2 and other structures, thereby affecting the normal operation of the cleaning device 100. On the other hand, the cover 13 can prevent dust and other impurities from falling onto the main body 1 and the dust box 3.

[0058] In this embodiment, the cover 13 is detachably connected to the main body 1. To remove the dust box 3, the user can first remove the cover 13 and then take out the dust box 3. The cover 13 can be connected to the main body 1 using a magnetic connection, a snap-on connection, or other methods. In some embodiments, the cover 13 can also be designed so that one portion is fixedly connected to the main body 1, such as by bonding or threading, while the other portion is reversible relative to the main body 1. To remove the dust box 3, the user can first lift up the reversible portion of the cover 13 and then remove the dust box 3.

[0059] In order to more conveniently disassemble and clean the dust box 3, please refer to Figure 5, which is a schematic structural diagram of another embodiment of the cleaning device described in Figure 2. In other embodiments, an opening window 130 is provided on the cover 13. The opening window 130 is used to avoid the dust box 3. The dust box 3 is installed in the installation cavity 120 through the opening window 130. By providing the opening window 130, the dust box 3 is completely accommodated in the main body 1 and is convenient for access to the dust box 3. In this embodiment, the cover 13 can be detachably connected to the main body 1 or fixedly connected to the main body 1. The connection method refers to the above embodiment and will not be repeated here.

[0060] Optionally, the main body 1 includes a mounting base 12 and a cover 13. The mounting base 12 defines a mounting cavity 120, and the dust box 3 is detachably disposed within the mounting cavity 120. The cover can be disposed on top of the mounting base 12 and cover the dust box 3. The cover 13 can cover the mounting cavity 120, i.e., cover the mounting cavity 120.

[0061] In some embodiments, as shown in FIG5 , the cover 13 may be provided with an opening window 130 , and the dust box 3 may be installed in or removed from the installation cavity 120 through the opening window 130 . The dust box 3 may be exposed to the outside through the opening window 130 .

[0062] In other embodiments, as shown in FIG2 , the cover 13 may not have a window, but may cover the dust box 3. The dust box 3 may be hidden inside the main body 1. When installing or removing the dust box 3, the cleaning device 100 may first remove the cover 13, and then install the dust box 3 into or remove it from the installation cavity 120.

[0063] Optionally, as shown in FIG3 , the dust box 3 of the cleaning device 10 is disposed within the main body 1, with the central axis of the main body 1 passing through the dust box 3. The dust box 3 can be stacked with the main body 1. The central axis of the main body 1 passing through the dust box 3 is, for example but not limited to, the central axis Y1 shown in FIG3 . The central axis Y1 is the central axis of the main body 1 extending along the forward direction of the cleaning device 100, i.e., the x-direction.

[0064] In some embodiments, the main body 1 is used to move on a work surface. The projection of the dust box 3 on the work surface is located within the projection of the main body 1 on the work surface. It is understandable that the work surface can be the surface to be cleaned by the cleaning device 100, such as but not limited to the ground. Optionally, two perpendicular central axes of the main body 1, such as the central axis Y1 and the central axis Y2 shown in Figure 3, both pass through the dust box 3. Among them, the central axis Y2 is, for example, the central axis of the main body 1 extending along the left and right directions. Among them, the dust box 3 can be located at the position where the central axis Y1 and the central axis Y2 overlap. In other embodiments, the dust box 3 can also be located at the position where two other central axes overlap, and the two central axes can be not only two perpendicular central axes, but also two central axes inclined at other angles, such as two central axes inclined at acute angles or obtuse angles.

[0065] The dust box 3 can be symmetrically arranged along the central axis of the main body 1, for example, symmetrically arranged along the central axis Y1, symmetrically arranged along the central axis Y2, or symmetrically arranged along both the central axis Y1 and the central axis Y2. In other embodiments, the dust box 3 can also be symmetrically arranged along other central axes of the main body 1.

[0066] Through the above design, the cleaning device 100 can set the dust box 3 in the middle of the main body 1 and stack it with the main body 1, so that other installation space of the main body 1, such as the tail space, can be used to install other cleaning mechanisms, which is conducive to enriching the design diversity of the cleaning device 100, and can also make the structural layout of the cleaning device 100 compact, which is conducive to reducing the volume of the cleaning device 100.

[0067] As needed, the cleaning device 100 can be configured to include a cleaning module, for example, at least one of a dry cleaning module and a wet cleaning module 5. In some embodiments, the cleaning device 100 includes a dry cleaning module, that is, a roller brush assembly 15 and a roller brush drive assembly (not shown) that drives the roller brush assembly 15. Specifically, a dust inlet 311 is also provided on the dust box 3. The positions of the roller brush assembly 15 and the dust box 3 are not limited. In this way, the roller brush assembly 15 works normally on the working surface, and the garbage or debris on the working surface is rolled up along the rotation direction of the roller brush assembly 15. The garbage or debris on the working surface enters the dust box 3 through the dust inlet 311 under the action of the airflow. It can be understood that in some embodiments, the dry cleaning module can also be omitted, and a dust suction port (not shown) is provided at the bottom of the main body 1 to suck the garbage or debris into the dust box 3 by pure suction.

[0068] In some other embodiments, the cleaning device 100 includes a wet cleaning module 5, which includes a wiping member 51 and a drive assembly 52 in transmission connection with the wiping member 51. The drive assembly 52 is mounted within the main body 1 and positioned behind the dust box 3 along the forward direction of the cleaning device 100. The wiping member 51 faces the work surface, and the drive assembly 52 can drive the wiping member 51 to clean the work surface, such as by rotating the wiping member 51 relative to the main body 1 or by vibrating the wiping member 51. Depending on the type of the wiping member 51, the drive assembly 52 can also drive the wiping member 51 away from or against the work surface. Positioning the drive assembly 52 behind the dust box 3 along the forward direction of the cleaning device 100 further reduces the size of the entire cleaning device 100 while ensuring a reasonable distribution of the center of gravity of the cleaning device 100, thereby preventing the cleaning device 100 from tilting due to the center of gravity being too far back.

[0069] It should be noted that in some embodiments, the cleaning device 100 may include both a dry cleaning module and a wet cleaning module 5. Depending on actual use, either the dry cleaning module or the wet cleaning module 5 may be used alone. For example, when the work surface is carpeted, the dry cleaning module may be used alone; or when the work surface is free of excess debris, the wet cleaning module 5 may be used alone. Alternatively, both the dry cleaning module and the wet cleaning module 5 may be used simultaneously.

[0070] Optionally, the wiping member 51 is provided at the bottom of the main body 1, and the driving assembly 52 is provided in the main body 1. Along the forward direction of the cleaning device 100, the driving assembly 52 can be located at the rear side of the dust box 3. In other words, the driving assembly 52 can be provided at the rear of the dust box 3.

[0071] In some embodiments, the cleaning device 100 may include multiple wiping members 51, such as the two wiping members 51 shown in FIG4 . The drive assemblies 52 may correspond one-to-one with the wiping members 511. The multiple drive assemblies 52 may all be located on the rear side of the dust box 3 along the forward direction of the cleaning device 100. The multiple wiping members 51 may be symmetrically arranged along the central axis of the main body 1, such as along the central axis Y1 extending in the forward direction of the cleaning device 100. The multiple drive assemblies 52 may also be symmetrically arranged along the central axis of the main body 1.

[0072] Optionally, along the forward direction of the cleaning device 100, the roller brush assembly 15 can be located at the front side of the dust box 3. The wiping member 51 can be located at the rear side of the dust box 3. The roller brush assembly 15 and the wiping member 51 are both arranged at the bottom of the main body 1.

[0073] Since the cleaning device 100 needs to map, locate, and avoid some obstacles on the work surface, such as furniture, living things, etc., when actually used, in some embodiments, the cleaning device 100 also includes an obstacle avoidance sensing device 6. Along the forward direction of the cleaning device 100, the obstacle avoidance sensing device is located on the front side of the entire main body 1. The obstacle avoidance sensing device 6 is used to detect whether there are obstacles on the travel route of the main body 1. The cleaning device 100 plans a walking route or determines a cleaning strategy based on the detection results of the obstacle avoidance sensing device 6.

[0074] Furthermore, to expand the detection range of the obstacle avoidance sensor 6, the obstacle avoidance sensor 6 protrudes from the top of the main body 1, enabling 360° detection. The obstacle avoidance sensor 6 can be a lidar or other sensing device, such as a time-of-flight sensor, camera, or infrared sensor. In other embodiments, the obstacle avoidance sensor 6 can also be installed inside the main body 1, with an avoidance window corresponding to the obstacle avoidance sensor 6 defined in the main body 1.

[0075] In this embodiment, the dust box 3 is located behind the obstacle avoidance sensing device 6, ensuring the rationality of the center of gravity distribution of the cleaning device 100, avoiding the center of gravity of the cleaning device 100 being too close to the front, and also avoiding the dust brought out when disassembling the dust box 3 from contaminating the obstacle avoidance sensing device 6.

[0076] Optionally, as shown in FIG3 , the cleaning device 100 includes an obstacle avoidance sensor 61 disposed on the main body 1. Along the forward direction of the cleaning device 100, the obstacle avoidance sensor 61 may be located in front of the dust box 3. Both the obstacle avoidance sensor 61 and the drive assembly 52 may be disposed within the main body 1. The dust box 3 may be disposed between the obstacle avoidance sensor 61 and the drive assembly 52. ​​In other embodiments, the obstacle avoidance sensor 611 and the drive assembly 52 may also be disposed elsewhere on the main body 1, such as at the top or front end of the main body 1.

[0077] In some embodiments, the cleaning device 100 may include an obstacle avoidance sensing device 6 and an obstacle avoidance sensor 61. The obstacle avoidance sensing device 6 is primarily used for navigation and mapping, and may be, for example, a radar. The obstacle avoidance sensor 61 is a sensor specifically designed for obstacle avoidance. Optionally, the obstacle avoidance sensor 61 may be a visual obstacle avoidance sensor. In other embodiments, the obstacle avoidance sensor may also be another type of sensor, such as a laser sensor.

[0078] In order to quickly and smoothly transport the dust and debris removed by the cleaning module into the dust box 3, the cleaning device 100 further includes an air suction assembly 2 for generating a suction airflow. The dust box 3 may be provided with an air suction port 313, and the air suction assembly 2 may be disposed on the main body 1 and communicate with the air suction port 313. In some embodiments, the air suction assembly 2 is mounted on the main body 1 and connected to the dust box 3. Specifically, the dust box 3 includes a box body 31 and a cyclone separator 32 disposed within the box body 31. Please refer to Figures 5 to 7 in conjunction with the above. The box body 31 may be provided with a dust inlet 311 and an air suction port 313. The dust inlet 311 is used to introduce the suction airflow, the air suction port 313 is used to discharge the suction airflow, and the cyclone separator 32 is used to separate the suction airflow from the garbage entering the box body 31 along with the suction airflow. The dust outlet 312 and the dust inlet 311 are both disposed on the box body 31. The suction end 211 of the air suction assembly 2 may be communicated with the air suction port 313. When the cleaning device 100 is operating normally on a work surface, the suction assembly 2 begins to operate. The suction airflow generated by the suction assembly 2 carries the garbage into the dust box 31 through the dust inlet 311 and then passes through the cyclone separator 32. The garbage and fine dust remain in the dust box 31 due to gravity and the action of the cyclone separator 32. The suction airflow flows out of the dust box 3 through the suction port 313.

[0079] To ensure effective suction separation, the height of the dust inlet 311 is lower than that of the air intake 313, thereby increasing the suction airflow path of the suction assembly 2. This allows the garbage entering the housing 31 through the dust inlet 311 to rise while rotating as the suction airflow passes through the cyclone separator 32 for cyclonic separation. At this point, the garbage in the suction airflow falls into the housing 31 due to the combined effects of gravity and collision separation with the cyclone separator 32. The suction airflow does not carry dust, preventing dust from entering the air intake 313 and potentially affecting or damaging the normal operation of the suction assembly 2 or even the entire cleaning device 100.

[0080] In some embodiments, when there is a lot of garbage inside the cleaning device 100, the cleaning effect may be poor due to insufficient suction force, and the air intake port 313 can be multiple, such as at least two, and correspondingly, there are at least two air intake components 2. Each air intake component 2 is arranged on the main body 1, and the air intake end 211 of each air intake component 2 is connected to the corresponding air intake port 313. Optionally, the number of air intake components 2 is at least two, and at least two air intake components 2 are arranged at intervals. In other embodiments, at least two air intake components 2 can be arranged in contact, that is, one air intake component 2 is next to another air intake component 2, which is conducive to shortening the air duct and improving the installation space utilization of the main body 1. Among them, the air intake component 2 and the air intake port 313 can correspond one to one.

[0081] On the one hand, providing multiple air intake ports 313 and corresponding multiple air intake assemblies 2 can solve the problem of insufficient air volume of the air intake assembly 2 when the cleaning device 100 is cleaning on a carpet or when there is large-sized garbage and debris on the ground. By adopting at least two air intake assemblies 2, the air volume that the air intake assembly 2 can provide can be doubled, further enhancing the cleaning ability of the cleaning device 100. On the other hand, when at least two air intake assemblies 2 are adopted, compared with the case of adopting only one air intake assembly 2, the two air intake assemblies 2 working simultaneously can improve the cleaning efficiency and shorten the cleaning time. Further, it can be understood that in order to maximize the cleaning efficiency of the cleaning device 100, in other embodiments, when a dry cleaning module and a wet cleaning module 5 are provided at the same time, two wet cleaning modules 5 are also provided, and are respectively provided at both ends of the two air intake assemblies 2, so that the area adsorbed by the roller brush assembly 15 is completely covered, thereby achieving a larger area to be mopped at one time. Of course, in some embodiments, only one set of air intake assemblies 2, or more than two sets of air intake assemblies 2, can also be used.

[0082] More preferably, at least two suction components 2 are arranged so that the directions of the suction airflows generated by each suction component 2 flowing out of the dust box 3 are different, that is, these suction components 2 are located in different directions of the dust box 3, so that the spatial structure of the suction component 2 is more reasonably utilized inside the entire cleaning device 100, and the noise of the cleaning device 100 can be reduced while avoiding mutual interference between the suction airflows. For example, the suction components 2 are arranged at intervals, and each suction component 2 is arranged crosswise between the center lines connecting the corresponding suction ports 313. More specifically, along the forward direction of the main body 1, each suction component 2 is arranged at the rear of the dust box 3 to ensure that the direction in which the dust is driven into the dust box 3 by the suction component 2 when working remains consistent, thereby accelerating the dust collection speed and enhancing the working efficiency of the cleaning device 100. The rear mentioned here can be understood as the rear, left rear or right rear. In other embodiments, according to the arrangement of the actual internal structure of the cleaning device 100, at least one of the at least two suction components 2 can be set on the left or right side of the dust box 3, or the two suction components 2 can be set on the left or right side of the dust box 3 respectively, leaving sufficient installation space for other structures in the cleaning device 100.

[0083] Continuing with reference to FIG7 , in some embodiments, an airflow chamber 316 communicating with the air intake port 313 is further provided in the box body 31. The airflow chamber 316 is located downstream of the cyclone separator 32, and the air intake port 313 is communicated with the airflow chamber 316. When the cleaning device 100 is in operation, each suction component 2 is in operation, and the suction airflow of each suction component 2 enters the cyclone separator 32, enters the airflow chamber 316, and then flows out from the air intake port 313. At this time, the garbage that enters the dust box 3 along with the suction airflow is separated and collected in the cyclone separator 32. The provision of the airflow chamber 316 can make the flow of the suction airflow smoother.

[0084] In order to avoid interference between the suction airflows of the suction components 2 and cause turbulence, in some specific embodiments, please continue to refer to Figure 6, a partition 317 is further provided in the airflow chamber 316. The partition 317 divides the airflow chamber 316 into at least two sub-airflow chambers 3160, and the sub-airflow chambers 3160 are connected to the suction ports 313 in a one-to-one correspondence. The number of partitions 317 is related to the number of suction components 2. It can be understood that when there are two suction components 2, there is one partition 317, which divides the airflow chamber 316 into two sub-airflow chambers 3160, each sub-airflow chamber 3160 is connected to an suction port 313, and each suction port 313 is connected to an suction component 2. Therefore, the suction airflow generated by the operation of the suction component 2 circulates in its respective sub-airflow chamber 3160 without interfering with each other in the airflow chamber 316, further improving the suction effect of the suction component 2. In other embodiments, the partition 317 may not be provided in the airflow chamber 316. The airflow cavity 316 may be an integrated cavity and communicate with each of the air inlets 313 respectively.

[0085] In order to prevent garbage and impurities from entering the suction assembly 2 along with the suction airflow, please refer to Figures 9 and 10. Figure 9 is a structural diagram of a connection method between the dust box and the suction assembly described in Figure 2; Figure 10 is a structural diagram of an embodiment of the suction assembly described in Figure 9. Each suction assembly 2 includes a suction fan 21 and a filter module 22. The filter module 22 is located between the suction port 313 and the suction fan 21. The filter module 22 filters the airflow processed by the dust box 3 and flows out of the airflow cavity 316 again, preventing fine dust from entering the interior of the suction assembly 2 along with the airflow, thereby affecting the normal operation of the suction assembly 2 and further affecting the normal operation of the cleaning device 100.

[0086] The airflow direction at the air inlet of the suction fan 21 is aligned with the airflow direction at the air outlet of the suction fan 21, thereby increasing the wind pressure generated by the suction fan 21 during operation, thereby improving the cleaning effect of the cleaning device 100. At the same time, the volume of the suction fan 21 can be reduced, thereby reducing the space occupied by the suction fan 21 within the main body 1, and further reducing the overall volume of the cleaning device 100. In this embodiment, the suction fan 21 can be an axial flow fan or a mixed flow fan. Furthermore, the suction fan 21 can also be equipped with a diffuser to further increase the wind pressure.

[0087] It can be understood that in some embodiments, the filter module 22 is detachably connected to the main body 1, and the user can clean or replace it after removing the filter module 22, thereby avoiding clogging of the filter module 22 after long-term use and reducing the cleaning effect of the cleaning device 100. It can also avoid the heating problem of the suction fan 21 caused by clogging of the filter module 22, thereby improving the service life of the entire cleaning device 100.

[0088] Furthermore, in this embodiment, each filter module 22 is configured to be detachable from the main body 1 after the dust box 3 is detached from the main body 1. That is, when the user detaches the filter module 22, the dust box 3 must be detached first. This ensures that the filter module 22 fits tightly against the dust box 3 and improves the sealing between the filter module 22 and the dust box 3. Of course, in some embodiments, the filter module 22 can also be configured to support independent detachment, that is, the detachment and assembly of the filter module 22 is not affected by the dust box 3.

[0089] In some embodiments, please continue to refer to Figures 10, 11, and 12. Figure 11 is an exploded structural diagram of an embodiment of the suction assembly described in Figure 10; Figure 12 is a structural schematic diagram of an embodiment of the filter element described in Figure 10. Each filter module 22 includes a fixing bracket 221 and a filter element 222. The fixing bracket 221 is detachable relative to the main body 1. The filter element 222 is mounted on the fixing bracket 221. The fixing bracket 221 is provided with an air hole 220. The air hole 220 is sealed and connected to the air inlet 313. The filter element 222 covers the air hole 220 and the air inlet 313 and is used to filter the suction air flowing through the air hole 220 and the air inlet 313. The fixing bracket 221 is used to install the filter element 222 and seal it with the dust box 3, and to prevent the filter element 222 from deforming.

[0090] It can be understood that since the air flow separated and filtered by the dust box 3 no longer carries larger particles of dust, in order to achieve further filtering effect of the filter element 222, in some embodiments, the filtering accuracy range of the filter element 222 is such that the purification rate of smaller dust of 0.1μm-0.3μm needs to reach 99.998%, further ensuring the effectiveness of the filter element 222 in filtering the suction air flow.

[0091] It is worth mentioning that in this embodiment, the filter module 22 is disposed outside the dust box 3, which not only simplifies the structure of the dust box 3 but also prevents the user from directly touching the interior of the dust box 3 and getting their hands dirty when removing and installing the filter module 22. In other embodiments, the filter module 22 may also be disposed inside the dust box 3, for example, between the cyclone separator 32 and the airflow chamber 316.

[0092] Furthermore, in some embodiments, each suction assembly 2 also includes a mounting bracket 23, which is connected to the main body 1. The suction fan 21 and the filter module 22 are both mounted on the mounting bracket 23. The mounting bracket 23 also includes a buffer pad 230. Two buffer pads 230 may be provided. The two buffer pads 230 are respectively mounted at both ends of the suction fan 21 and abut against the mounting bracket 23 to provide shock absorption for the suction fan 21. When the suction fan 21 is operating, the buffer pads 230 can absorb some of the vibration and noise generated by the suction fan 21, thereby improving the user experience of the entire cleaning device 100.

[0093] Specifically, referring to FIG11 , the mounting bracket 23 includes a first accommodating chamber 231 and a second accommodating chamber 232, and the mounting bracket 23 abuts against the peripheral wall of the box body 31. The first accommodating chamber 231 covers the air intake port 313. The air intake end 211 of the air intake fan 21 faces the first accommodating chamber 231. The air intake assembly 2 draws dust and debris from a working surface such as the floor of a house into the dust collection box 3 through the air intake port 313. The filter module 22 is installed in the first accommodating chamber 231, and the air intake fan 21 is installed in the second accommodating chamber 232. This allows the filter module 22 to be additionally provided without interfering with the normal operation of the air intake fan 21, further preventing dust and debris from passing through the air intake port 313 along with the airflow when the air intake fan 21 is sucking the interior of the dust collection box 3.

[0094] Further, referring to Figure 12, in some embodiments, the filter module 22 further includes a sealing gasket 223. Two sealing gaskets 223 are provided, wherein one sealing gasket 223 is provided between the fixing bracket 221 and the inner wall of the first accommodating chamber 231, and is used to stably fix the entire filter module 22 in the first accommodating chamber 231. The other sealing gasket 223 is provided between the air hole 220 and the air inlet 313 to achieve a close seal at the air inlet 313, thereby preventing the suction airflow from overflowing from the connection between the filter element 222 and the fixing bracket 221, which would cause smaller dust to enter the interior of the cleaning device 100 along the gap in the connection, causing dust accumulation. In severe cases, abnormal noise would be generated, affecting the user experience of the entire cleaning device 100.

[0095] It is understandable that in order to smoothly discharge the suction airflow generated by the suction fan 21 when it is in operation from the suction assembly 2, referring to Figures 1 and 11, in some embodiments, an exhaust duct 234 is further provided on the mounting bracket 23. The suction airflow entering from the suction end 211 of the suction fan 21 flows out from the air outlet end 212 of the suction fan 21, and flows out of the suction assembly 2 through the exhaust duct 234, and then is discharged from the cleaning device 100. In the present application, the filter module 22, the suction fan 21, and the exhaust duct 234 are all mounted or integrated on the mounting bracket 23, resulting in a simple structure. The suction assembly 2 occupies less space, which can make the overall volume of the cleaning device smaller.

[0096] In order to improve the separation and collection effect of the dust box 3 and avoid blockage, please refer to Figures 6 and 7. Figure 6 is a schematic diagram of the exploded structure of an embodiment of the dust box described in Figure 2; Figure 7 is a schematic diagram of the structure of the box body described in Figure 6. In some embodiments, the cyclone separator 32 is connected to the box body 31 to form a first sub-dust collecting chamber 33 and a second sub-dust collecting chamber 34 that are interconnected. The dust inlet 311 is connected to the first sub-dust collecting chamber 33, and the air intake 313 is connected to the second sub-dust collecting chamber 34. The dust outlet 312 is connected to the first sub-dust collecting chamber 33 and the second sub-dust collecting chamber 34. When the cleaning device 100 is cleaning the work surface, the suction component 2 starts working. The suction airflow generated by the suction component 2 enters the first sub-dust collecting chamber 33 from the dust inlet 311, passes through the cyclone separator 32, and flows out from the air intake 313. In the direction of the suction airflow, the first sub-dust collecting chamber 33 is located upstream of the second sub-dust collecting chamber 34. When the garbage enters the dust box 3, the cleaning device 100 of the present application uses the cyclone separator 32 to first filter the larger garbage and collect it in the first sub-dust collecting chamber 33; the garbage with smaller particles, such as dust, enters the cyclone separator 32, and the suction effect inside the cyclone separator 32 forms a cyclone, which generates centrifugal force so that all the garbage gathers in the center of the cyclone and falls into the second sub-dust collecting chamber 34. Finally, the garbage in the first sub-dust collecting chamber 33 and the garbage in the second sub-dust collecting chamber 34 can be discharged from the dust outlet 312, thereby collecting garbage of different particle sizes and preventing the smaller particles from causing blockage in the dust box 3 or entering the suction component 2 with the airflow, thereby affecting the suction component 2. When the cleaning device 100 is docked with the dust collection station 200, the docking port 201 is connected to the dust outlet 312, and the fan 202 in the station works to allow the dust collected in the dust box 3 to flow into the dust holding chamber 203 through the dust outlet 312, the dust collection channel 11, the docking port 201 and the channel 204, thereby realizing the collection and processing of garbage of different particle sizes.

[0097] Specifically, the cyclone separator 32 includes a filter housing 321 and a cyclone tube assembly 322. The filter housing 321 is positioned outside the cyclone tube assembly 322 and prioritizes filtering larger waste. The suction airflow passes through the filter housing 321 from the first sub-dust collection chamber 33 and into the cyclone tube assembly 322. The first sub-dust collection chamber 33 is used to collect waste intercepted by the filter housing 321, while the second sub-dust collection chamber 34 is used to collect waste separated by the cyclone tube assembly 322. This completes secondary dust filtration and collection, further preventing some dust from entering the suction assembly 2 with the airflow and affecting it.

[0098] Specifically, please refer to Figure 13, which is a structural diagram of another embodiment of the dust collection box described in Figure 2. In some embodiments, the box body 31 includes a bottom wall 318 and a side wall 319 connected to the bottom wall 318. The bottom wall 318 and the side wall 319 form a receiving chamber 310, and the cyclone separator 32 is accommodated in the receiving chamber 310. The filter housing 321 divides the receiving chamber 310 into a first sub-dust collecting chamber 33 and a second sub-dust collecting chamber 34. For example, in one example, the filter housing 321 is installed in the receiving chamber 310 and connected to the bottom wall 318. The filter housing 321 can be plate-shaped or cylindrical. When the filter housing 321 is plate-shaped, the first sub-dust collecting chamber 33 and the second sub-dust collecting chamber 34 are respectively located on both sides of the filter housing 321, and are respectively surrounded by the bottom wall 318, the side wall 319 and the filter housing 321. When the filter housing 321 is cylindrical, a first sub-dust collection chamber 33 is formed between the bottom wall 318, the side wall 319, and the outer wall of the filter housing 321; and a second sub-dust collection chamber 34 is formed between the bottom wall 318 and the inner wall of the filter housing 321. Of course, it is understood that when the filter housing 321 is cylindrical, it can be cylindrical or have other shapes.

[0099] Specifically in this embodiment, the first sub-dust collecting chamber 33 is arranged around the second sub-dust collecting chamber 34. Specifically, the second sub-dust collecting chamber 34 is located inside the first sub-dust collecting chamber 33.

[0100] More preferably, in order to simultaneously ensure the dust separation efficiency and durability of the filter housing 321, with reference to FIG6 , in some embodiments, the filter housing 321 is annular and cylindrical. The cross-section of the receiving chamber 310 is circular, perpendicular to the direction of gravity, and the cross-section of the filter housing 321 is annular. The filter housing 321 is concentrically disposed within the receiving chamber 310, and the first sub-dust collection chamber 33 is disposed around the second sub-dust collection chamber 34. This arrangement allows the suction airflow to flow along the inner wall of the receiving chamber 310, thereby improving the centrifugal separation effect between large particles of waste and the suction airflow. Furthermore, after the suction airflow enters the cyclone separator 32, the cyclone separator 32 ensures the separation effect of small particles of waste from the suction airflow.

[0101] In order to increase the speed and efficiency of the subsequent discharge of dust from the dust box 3, the dust outlet 312 on the dust box 3 may be provided with one or more dust outlets. The following will describe in detail the dust outlet 312 configuration structure of the dust box 3 by category:

[0102] Example 1:

[0103] Please refer to Figures 13 and 14. Figure 14 is a cross-sectional view of another embodiment of the dust box described in Figure 2. In embodiment 1, the dust box 3 has one dust outlet 312. At this time, part of the dust outlet 312 is connected to the first sub-dust collecting chamber 33, and part of the dust outlet 312 is connected to the second sub-dust collecting chamber 34. That is, the first sub-dust collecting chamber 33 and the second sub-dust collecting chamber 34 share one dust outlet 312. According to the arrangement of the first sub-dust collecting chamber 33 and the second sub-dust collecting chamber 34, the dust outlet 312 is set on the bottom wall 318 or the side wall 319. At this time, the garbage collected in the first sub-dust collecting chamber 33 and the second sub-dust collecting chamber 34 is discharged through the dust outlet 312 at the same time when it is necessary to discharge the dust box 3. For example, in the embodiments shown in Figures 6, 13, and 14, the dust outlet 312 can be directly provided on the bottom wall 318 or on the side wall 319. When the dust outlet 312 is provided on the side wall 319, a separate process channel can be provided for the second sub-dust collecting chamber 34, and the process channel extends to communicate with the dust outlet 312. In the embodiment in which the first sub-dust collecting chamber 33 and the second sub-dust collecting chamber 34 are both surrounded by the bottom wall 318, the side wall 319, and the filter housing 321, the dust outlet 312 can be provided on the bottom wall 318 or on the side wall 319.

[0104] When the dust outlet 312 is set on the side wall 319, with Figure 14 as a reference, the inner wall surface of the accommodating cavity 310 includes at least a portion of the curved surface 3101, and the dust outlet 312 of the side wall 319 is set on the curved surface 3101, and the opening direction of the dust outlet 312 is tangent to the curved surface 3101, ensuring that when the cleaning device 100 is docked with the dust collection station 200 for dust collection operation, the garbage can smoothly leave the dust outlet 312 along the curved surface 3101 with the airflow.

[0105] It is understood that in order to prevent the garbage collected in the dust box 3 from spilling out of the dust box 3 during normal operation of the cleaning device 100 due to the normal operation of the cleaning device 100 or collisions caused by encountering obstacles, please refer to Figures 7 and 8. Figure 8 shows a cross-sectional view of the dust box described in Figure 6. In this embodiment, the dust box 3 also includes a baffle door 314, which is pivotally connected to the box body 31 and is used to cover or open the dust outlet 312. When the cleaning device 100 is disconnected from the dust collection station 200 or the fan 202 in the station is not operating, the baffle door 314 covers the dust outlet 312. When the cleaning device 100 is docked with the dust collection station 200 and the garbage collected in the first sub-dust collection chamber 33 and the second sub-dust collection chamber 34 needs to be discharged, the suction force generated by the fan 202 in the station drives the baffle door 314 to pivot to open the dust outlet 312, so that the garbage can enter the dust collection channel 11 through the dust outlet 312 and enter the dust collection station 200 under the action of the fan 202 in the station. It is not difficult to understand that when the dust collection station 200 completes the dust collection operation of the cleaning device 100, the baffle door 314 returns to the state of closing the dust outlet 312. The baffle door 314 can be reset under the action of a spring (not shown) or can be made of an elastic material. Of course, in other embodiments, the baffle door 314 can also be set to an electric form, that is, it is driven by a motor (not shown) to drive its movement so that the baffle door 314 opens or closes the dust outlet 312.

[0106] Further, in this embodiment, please refer to Figure 15, which is a structural diagram of an embodiment of the dust collection channel in the first embodiment proposed in this application. The main body 1 has one dust collection channel 11, which is provided with a dust inlet port 111 and a dust outlet port 112. The dust inlet port 111 and the dust outlet port 112 are both one. The dust inlet port 111 is connected to the dust outlet port 312. The dust outlet port 112 is used to connect to the docking port 201 of the dust collection station 200. When the dust collection station 200 performs dust collection operation on the cleaning device, the garbage inside the first sub-dust collection chamber 33 and the second sub-dust collection chamber 34 enters the dust collection channel 11 through the same dust outlet port 312, and then enters the dust holding chamber 203 through the docking port 201 and the channel 204. At this time, since there is only one dust outlet port 112, the dust collection station 200 is also provided with only one docking port 201.

[0107] Example 2:

[0108] In the second embodiment, please refer to Figures 16 and 17. Figure 16 is a schematic diagram of the structure of an embodiment of the dust collection channel in the second embodiment proposed in this application; Figure 17 is a schematic diagram of the structure of another embodiment of the dust collection channel in the second embodiment proposed in this application. There are two dust outlets 312, including a first dust outlet 3121 and a second dust outlet 3122 set at intervals. The first dust outlet 3121 is connected to the first sub-dust collection chamber 33, and the second dust outlet 3122 is connected to the second sub-dust collection chamber 34, ensuring that garbage with different weights and sizes in the first sub-dust collection chamber 33 and the second sub-dust collection chamber 34 can be discharged through different dust outlets 312. By setting the first dust outlet 3121 and the second dust outlet 3122 separately, it is ensured that when the fan 202 in the station is working, the garbage in the first sub-dust collection chamber 33 and the second sub-dust collection chamber 34 can leave the dust box 3 from the appropriate dust outlet 312.

[0109] Furthermore, the first dust outlet 3121 and the second dust outlet 3122 can be simultaneously provided on the bottom wall 318 or on the side wall 319. Alternatively, one of the first dust outlet 3121 and the second dust outlet 3122 can be provided on the side wall 319 and the other on the bottom wall 318. As shown in FIG7 , preferably, considering that the first sub-dust collecting chamber 33 stores larger particles of garbage, the first dust outlet 3121 can be provided on the side wall 319, while the first sub-dust collecting chamber 33 is provided around the second sub-dust collecting chamber 34, and the second dust outlet 3122 can be provided on the bottom wall 318. This structure is not only simple, but also enables larger particles of garbage to smoothly leave the dust collecting box 3 from the first dust outlet 3121, and smaller particles of garbage to smoothly leave the dust collecting box 3 from the second dust outlet 3122.

[0110] Similarly, similar to the first embodiment, for the first dust outlet 3121 and the second dust outlet 3122 that are simultaneously provided on the bottom wall 318 or the side wall 319, in order to prevent garbage from being scattered from the first dust outlet 3121 and the second dust outlet 3122, the box body 31 can also be provided with only one baffle door 314, and the baffle door 314 is used to cover or open the first dust outlet 3121 and the second dust outlet 3122 at the same time.

[0111] Understandably, since the first dust outlet 3121 and the second dust outlet 3122 are spaced apart in this second embodiment, as shown in FIG16 , in order to avoid problems such as a baffle door 314 not closing tightly or a baffle door 314 being too large, which would require too much suction force to open, thereby causing the fan 202 in the station to be unable to open the first dust outlet 3121 and the second dust outlet 3122 when docking with the dust collection station 200, in one embodiment, the box body 31 may further be provided with a first baffle door 3141 and a second baffle door 3142, wherein the first baffle door 3141 is used to cover or open the first dust outlet 3121, and the second baffle door 3142 is used to cover or open the second dust outlet 3122. When the cleaning device 100 is docked with the dust collection station 200 and the garbage collected in the first sub-dust collection chamber 33 and the second sub-dust collection chamber 34 needs to be discharged, the suction force generated by the fan 202 in the station drives the first baffle door 3141 and the second baffle door 3142 to open the first dust outlet 3121 and the second dust outlet 3122 respectively, so that the garbage in the first sub-dust collection chamber 33 can enter the dust collection channel 11 from the first dust outlet 3121 and the garbage in the second sub-dust collection chamber 34 can enter the dust collection channel 11 from the second dust outlet 3122, and enter the dust collection station 200 under the action of the fan 202 in the station.

[0112] Similarly, when one of the first dust outlet 3121 and the second dust outlet 3122 is disposed on the side wall 319, as in the first embodiment, the inner wall surface of the accommodating chamber 310 includes at least a portion of the curved surface 3101, the first dust outlet 3121 and / or the second dust outlet 3122 disposed on the side wall 319 are disposed on the curved surface 3101, and the opening direction of the first dust outlet 3121 and / or the second dust outlet 3122 is tangent to the curved surface 3101. Furthermore, the opening and closing methods of the baffle door, the first baffle door, and the second baffle door are the same as in the first embodiment and are not further described here.

[0113] It is understandable that the above-mentioned embodiment 2 is only described with two dust outlets. In practice, the number of dust outlets 312 in the cleaning device 100 can also be set to be greater than 2. When multiple dust outlets 312 are provided, there can be at least one first dust outlet 3121 that is in communication with the first sub-dust collecting chamber 33, and at least one second dust outlet 3122 that is in communication with the second sub-dust collecting chamber 34. Multiple first dust outlets 3121 and multiple second dust outlets 3122, as well as multiple baffle doors 314 that cover or open the multiple dust outlets 312, can also be provided. The specific structure can be referred to the setting in embodiment 2 and will not be repeated here.

[0114] In the second embodiment, the dust collecting channel 11 of the main body 1 can be provided with one dust collecting channel 11 or multiple dust collecting channels 11, etc. The specific structure is as follows:

[0115] When the dust collection channel 11 is set to one, the dust collection channel 11 is provided with at least one dust inlet port 111 and one dust outlet port 112. Correspondingly, the number of the docking ports 201 of the dust collection station 200 is the same as the number of the dust outlet ports 112, which is also one. In one embodiment, the number of the dust inlet ports 111 is the same as the number of the dust outlet ports 312. Since the second embodiment takes two dust outlet ports 312 as an example, the corresponding dust inlet ports 111 are described as being set to two. When there are two dust inlet ports 111, the two dust inlet ports 111 are respectively docked with the first dust outlet port 3121 and the second dust outlet port 3122. The two dust inlet ports 111 are connected to the same dust outlet port 112. The dust outlet port 112 is used to connect to the docking port 201 of the dust collection station 200. Under the action of the fan 202 in the station, the garbage in the first sub-dust collecting chamber 33 enters the dust collecting channel 11 through the first dust outlet port 3121 and the corresponding dust inlet port 111, and the garbage in the second sub-dust collecting chamber 34 enters the dust collecting channel 11 through the second dust outlet port 3122 and the corresponding dust inlet port 111. The garbage entering the dust collecting channel 11 enters the dust holding chamber 203 through the same dust outlet port 112 and the docking port 201.

[0116] In other embodiments, as shown in FIG17 , the number of dust inlet ports 111 may be smaller than the number of dust outlet ports 312. For example, only one dust inlet port 111 may be provided, and the inner diameter of the dust inlet port 111 is larger so as to surround and cover all dust outlet ports 312, such as the first dust outlet port 3121 and the second dust outlet port 3122. Alternatively, if there are two dust inlet ports 111 and three dust outlet ports 312, two of the dust outlet ports 312 may share one dust inlet port 111.

[0117] When there are multiple dust collection channels 11, the dust collection channels 11 can be designed to be the same as the number of dust outlets 312. Since the second embodiment takes two dust outlets 312 as an example, the corresponding dust collection channels 11 are described as being set to two. At this time, each dust collection channel 11 is provided with a dust inlet port 111 and a dust outlet port 112, and each dust inlet port 111 is connected to the corresponding dust outlet 312. In other words, the garbage in the first sub-dust collection chamber 33 enters the corresponding dust collection channel 11 through the first dust outlet 3121, and the garbage in the second sub-dust collection chamber 34 enters the other dust collection channel 11 through the second dust outlet 3122.

[0118] As for the docking ports 201 of the dust collection station 200, the number of docking ports 201 can be the same as the number of dust outlet ports 112, or can be less than the number of dust outlet ports 112. When the number of docking ports 201 is the same as the number of dust outlet ports 112, each dust outlet port 112 is used to dock with one docking port 201. When the number of docking ports 201 is less than the number of dust outlet ports 112, at least one docking port 201 is used to dock with at least two dust outlet ports 112 simultaneously.

[0119] Since the first sub-dust collecting chamber 33 contains larger garbage, in order to thoroughly collect these large particles of garbage into the dust collecting station 200, in some embodiments, the suction component 2 can be turned on as needed after the fan 202 in the station has been working for a first preset time and work together with the fan 202 in the station for a second preset time. For specific explanation, the embodiment shown in Figure 7 is used, that is, the first sub-dust collecting chamber 33 is correspondingly provided with a first baffle door 3141, and the second sub-dust collecting chamber 34 is correspondingly provided with a second baffle door 3142. During the first preset time of the fan 202 in the station, the first baffle door 3141 and the second baffle door 3142 are both in the open state under the adsorption effect of the fan 202 in the station. During this period, at least the small particles of garbage in the second sub-dust collecting chamber 34 can quickly enter the dust collecting station 200. When the suction fan 21 of the suction assembly 2 is turned on, the suction airflow generated by the suction fan 21 drives the second baffle door 3142 to pivot and close, so that the airflow generated by the station fan 202 can be fully used to suck the garbage in the first sub-dust collection chamber 33, so that the garbage in the first sub-dust collection chamber 33 can completely enter the dust collection station 200. Specifically, the cleaning system also includes a controller (not shown), which is connected to the station fan 202 and the suction assembly 2. The controller controls the suction fan 21 and the station fan 202 to work according to the first preset time length and the second preset time length according to preset conditions, thereby ensuring that the garbage in the dust collection box 3 can be completely cleaned.

[0120] To facilitate the removal and replacement of the cyclone separator 32, in some embodiments, the body 31 of the dust box 3 further includes a cover 315 disposed opposite the bottom wall 318 and detachably connected to the side wall 319. The cyclone separator 32 is detachably connected to the cover 315, and the dust inlet 311 is disposed on the side wall 319. The airflow chamber 316, the partition 317, and the air intake 313 are all disposed on the cover 315, ensuring that the suction airflow within the dust box 3 can flow over a relatively long distance during normal operation of the suction assembly 2. When the user removes the cover 315, the cyclone separator 32 is also removed, allowing the user to directly clean the inner wall of the receiving chamber 310. When the cyclone separator 32 needs to be cleaned, the cyclone separator 32 can be removed from the cover 315.

[0121] More specifically, the cyclone tube assembly 322 includes a plurality of tapered tubes 3220, each of which is mounted on the cover 315. Each tapered tube 3220 is hollow, with its opposite ends communicating with the second sub-dust collection chamber 34 and the corresponding sub-airflow chamber 3160, respectively. Furthermore, the inner diameter of each tapered tube 3220 facing the sub-airflow chamber 3160 is larger than the inner diameter facing the second sub-dust collection chamber 34. The axis of each tapered tube 3220 and the centerline of the second sub-dust collection chamber 34 are both parallel to the direction of gravity. Among them, the airflow after the first filtration by the filter shell 321 carries smaller garbage and enters different conical tubes 3220 respectively. Multiple conical tubes 3220 perform secondary separation simultaneously, which on the one hand speeds up the separation speed of garbage and suction airflow, and on the other hand can generate a cyclone effect inside the cyclone tube group 322. Compared with the situation where all the garbage is separated in a single conical tube 3220, it avoids some dust from not being able to rotate along the side wall of the conical tube 3220 along with the cyclone when the cyclone occurs, and then enters the suction component 2 with the suction airflow, which affects the normal operation of the suction component 2.

[0122] In addition, in order to be able to fix the cyclone tube group 322 more firmly inside the dust box 3, please continue to refer to Figures 6 and 8. In some embodiments, the dust box 3 also includes a connecting bracket 35, a first connecting bracket 351 is fixed to the cover body 315, and the cyclone tube group 322 is installed on the first connecting bracket 351 to avoid the cyclone tube group 322 from shaking due to the impact of the airflow on the side wall of the cyclone tube group 322 when a cyclone effect is generated inside the cyclone tube group 322, thereby affecting the internal cyclone effect, so that the dust heavier than the airflow cannot be completely separated and enters the airflow cavity 316 with the airflow, thereby affecting the normal function of the entire dust box 3. A hollow air inlet pipe 350 is provided on the side of the first connecting bracket 351 facing away from the cover body 315. Each hollow air inlet pipe 350 is located in the corresponding cyclone tube group 322, and each hollow air inlet pipe 350 connects the air flow cavity 316 and the corresponding cyclone tube group 322. The lighter air flow separated by the cyclonic action inside the cyclone tube group 322 is sent into the air flow cavity 316 through the hollow air inlet pipe 350.

[0123] On the other hand, the dust box 3 further includes a second connecting bracket 352 , which is also used to support the cyclone tube group 322 , so that one end of the cyclone tube group 322 away from the cover body 315 is fixed to the second connecting bracket 352 .

[0124] The dust box 3 also includes a third connecting bracket 353, which supports and connects the filter housing 321, stably securing the filter housing 321 to the second connecting bracket 352 and the cover 315, thereby preventing the filter housing 321 from shaking due to airflow. Furthermore, in the embodiment shown in FIG8 , the third connecting bracket 353 abuts against the bottom wall to form a portion of the second sub-dust collection chamber 34. In other embodiments, the third connecting bracket 353 may be omitted, and the filter housing 321 may directly abut against the bottom wall to form the second sub-dust collection chamber 34.
