Description

Technical Field

[0001] The present application relates to the technical field of intelligent appliances, in particular to a dust collection box, a cleaning device and a cleaning system. Background Art

[0002] With the development of the times, cleaning devices that can liberate hands have emerged as the times require and have gradually become essential cleaning helpers for people, effectively replacing manual cleaning.

[0003] Existing cleaning devices include a dust collection box and a suction assembly. During cleaning, under the action of the suction assembly, the garbage cleaned out enters the dust collection box. When the cleaning is completed or the garbage in the dust collection box is collected to a certain amount, the garbage in the dust collection box is transported away. As the fan power of the sweeping robot is getting larger and larger, along with the rapid iterative growth of the suction force, the cleaning device can handle finer garbage, such as dust. However, dust particles are more likely to adhere to the filter screen of the existing dust collection box, resulting in the blockage of the filter screen and reducing its cleaning effect. And after the user uses the cleaning device, the filter screen needs to be frequently replaced and the dust collection box needs to be manually cleaned, which affects the user experience. Summary of the Invention

[0004] The present application provides a dust collection box, which can avoid fine particles, such as dust, from being blocked in the dust collection box during the collection of garbage, thereby affecting the cleaning effect of the dust collection box and other problems.

[0005] To solve the above technical problems, a dust collection box proposed in the present application includes a box body and a cyclone separator disposed in the box body. The box body is provided with a dust inlet, a dust outlet and a suction port. The cyclone separator is connected to the box body to form a first sub-dust collection cavity and a second sub-dust collection cavity that communicate with each other. The dust inlet communicates with the first sub-dust collection cavity, the suction port communicates with the second sub-dust collection cavity, and the dust outlet communicates with the first sub-dust collection cavity and the second sub-dust collection cavity. The suction port is used to communicate with a suction assembly, and the suction airflow generated by the suction assembly enters the first sub-dust collection cavity from the dust inlet, passes through the cyclone separator, and flows out from the suction port. In the direction of the suction airflow, the first sub-dust collection cavity is located upstream of the second sub-dust collection cavity.

[0006] Another technical solution proposed in the present application is to provide a cleaning device, including a main body, a suction assembly and a dust collection box. The dust collection box is the dust collection box described above, and the dust collection box is detachably disposed on the main body. The suction assembly is installed on the main body and communicates with the corresponding suction port; a walking wheel assembly is installed on the main body and is used to drive the cleaning device to walk on the working surface.

[0007] Another technical solution proposed by this application is: to provide a cleaning system, including a dust collection station and a cleaning device. The dust collection station includes a docking port, an in-station fan, a dust storage chamber and a channel. The channel connects the docking port and the dust storage chamber, and the suction port of the in-station fan is connected to the dust storage chamber. The cleaning device is the cleaning device described above, and the cleaning device is detachably or dockably connected to the dust collection station. When the cleaning device is docked and connected to the dust collection station, the docking port is communicated with the dust outlet, and the in-station fan operates to enable the dust collected in the dust collection box to flow through the dust outlet and the channel into the dust storage chamber.

[0008] The beneficial effect of this application is: Compared with the existing dust collection box, the dust collection box proposed by this application includes a box body and a cyclone separator arranged in the box body. The box body is provided with a dust inlet, a dust outlet and a suction port. The dust inlet is used to send garbage into the interior of the dust collection box. The cyclone separator is connected to the box body to form a first sub-dust storage chamber and a second sub-dust storage chamber that communicate with each other. The dust inlet is communicated with the first sub-dust storage chamber, and the suction port is communicated with the second sub-dust storage chamber. The dust outlet is communicated with the first sub-dust storage chamber and the second sub-dust storage chamber. Under the action of the suction air flow generated by the suction component, the garbage enters the dust collection box from the dust inlet. The cyclone separator first filters the garbage with larger particles, so that the garbage with larger particles is contained in the first sub-dust storage chamber. The garbage with smaller particles, such as dust, enters the cyclone separator. The suction air flow forms a cyclone inside the cyclone separator, and the generated centrifugal force separates the garbage with smaller particles from the suction air flow and falls into the second sub-dust storage chamber. Finally, the garbage in the first sub-dust storage chamber and the garbage in the second sub-dust storage chamber can be discharged from the dust outlet. The dust collection box of this application can collect garbage with different particle sizes, and can prevent the garbage with smaller particles from clogging in the dust collection box or entering the suction component along with the air flow, affecting the suction component.

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. According to the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0028] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0029] In one aspect of the present application, a cleaning system is provided. In a specific embodiment, please refer to Figure 1 , Figure 1 is a 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 floor sweeping robot, a mopping robot, a sweeping and mopping integrated robot, etc., and is used to vacuum, clean, and even wet mop the floor of a house. Moreover, the cleaning device 100 can be separated from the dust collection station 200 and perform cleaning work independently, and store the dust and sundries collected during the cleaning or vacuuming process. When the cleaning device 100 finishes working or the stored dust and sundries reach the preset capacity, the cleaning device 100 is docked and connected to the dust collection station 200, and the dust collection station 200 centrally collects the dust and sundries stored in the cleaning device 100.

[0030] In order to ensure that the dust collection station 200 can achieve unified treatment of dust and sundries, please continue to refer to Figure 1 , in some embodiments, the dust collection station 200 includes a docking interface 201, an in-station fan 202, a dust storage cavity 203, and a channel 204. The channel 204 communicates the docking interface 201 and the dust storage cavity 203. The air suction port 2021 of the in-station fan 202 communicates with the dust storage cavity 203. The cleaning device 100 includes a main body 1 and a dust collection box 3. The dust collection box 3 is detachably arranged on the main body 1, and the dust collection box 3 is provided with a dust outlet 312.

[0031] When the cleaning device 100 is docked and connected to the dust collection station 200, the docking port 201 is communicated with the dust outlet 312. The fan 202 in the station operates to suck the area where the dust collection station 200 is docked with the cleaning device 100. Under the suction force of the fan 202 in the station, the garbage and dust in the dust collection box 3 can flow from the dust outlet 312 into the docking port 201 under the action of the air flow, and enter the dust storage cavity 203 through the channel 204.

[0032] It can be understood that in some embodiments, a garbage bag (not shown in the figure) can be additionally installed in the dust storage cavity 203, so as to completely collect the dust or garbage in the garbage bag. When it is necessary to process the garbage in the dust storage cavity 203, open the cover body (not shown in the figure) of the dust storage cavity 203, and just throw away the installed garbage bag to realize rapid garbage disposal.

[0033] 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 communicates 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 communicated with the corresponding dust outlet 312, and the dust outlet port 112 is communicated with the docking port 201. In order to improve the dust outlet efficiency, the number of the dust outlets 312 can be multiple, and according to the number of the dust outlets 312, the dust collection channels 11 can also be set to be corresponding multiple; or, the number of the dust inlet ports 111 of the dust collection channels 11 is set to be multiple corresponding to the dust outlets 312. Similarly, in order to facilitate the docking and connection between the cleaning device 100 and the dust collection station 200, the number of the docking ports 201 is the same as the number of the dust outlet ports 112. According to needs, the docking port 201 and the dust outlet port 112 can be set to one or set to be corresponding multiple. The specific structure will be described in detail in combination with the specific structures of the main body 1 and the dust collection box 3 hereinafter.

[0034] Please refer to Figures 2 to 4 , Figure 2 is Figure 1 a schematic structural diagram of an embodiment of the cleaning device described in Figure 3 is Figure 2 a top view of the cleaning device described in Figure 4 is Figure 2The bottom view of the cleaning device described in [reference]. Specifically, the cleaning device 100 further includes a walking wheel assembly 4. The walking wheel assembly 4 is connected to the main body 1 and is supported on the working surface and can move on the working surface. Among them, when projected along the direction towards the working surface, the projection of the dust collection box 3 is located within the projection of the main body 1. That is to say, the position of the dust collection box 3 can be set in any area inside the contour of the main body 1 according to actual design requirements, as long as the projection of the dust collection box 3 is located within the projection of the main body 1 when projected along the direction towards the working surface. Therefore, on the one hand, it is more conducive to the design diversity of the entire cleaning device 100. On the other hand, it avoids that when the overall design of the cleaning device 100 is carried out, the dust collection box 3 is additionally arranged outside the main body 1, resulting in an overly large overall volume of the cleaning device 100, making it unable to enter the gaps between some furniture and the ground, creating cleaning dead spots when the cleaning device 100 is working.

[0035] Among them, the walking wheel assembly 4 includes a first walking wheel 41 and a second walking wheel 42. Both the first walking wheel 41 and the second walking wheel 42 are connected to the main body 1. And along the forward direction of the cleaning device, which is also the Figure 3 X direction in [reference], the first walking wheel 41 and the second walking wheel 42 are respectively located on the left and right sides of the dust collection box 3. It should be noted that the first walking wheel 41 and the second walking wheel 42 being respectively located on the left and right sides of the dust collection box 3 can mean that the dust collection box 3 is offset from the first walking wheel 41 and the second walking wheel 42 in the X direction, or that on the projection plane perpendicular to the left-right direction, there is an overlapping area between the projection of the dust collection box 3 and the projections of the first walking wheel 41 and the second walking wheel 42, and it can be reasonably arranged according to the center of gravity of the cleaning device.

[0036] It can be understood that in some embodiments, the cleaning device 100 further includes a universal wheel 14, which is used to support the main body 1 and assist the first walking wheel 41 and the second walking wheel 42 in moving, and when the cleaning device 100 needs to change the traveling direction, it turns to assist in realizing the turning and avoidance of the cleaning device 100.

[0037] To facilitate the disassembly of the dust collection box 3, specifically, the main body 1 includes a mounting base 12. The mounting base 12 is provided with a mounting cavity 120. The mounting cavity 120 is recessed from the top to the bottom of the mounting base 12. The dust collection box 3 is detachably mounted in the mounting cavity 120, facilitating the disassembly of the dust collection box 3 for separate cleaning. Moreover, the disassembly and assembly direction of the dust collection box 3 relative to the mounting base 12 is the up and down direction. That is, the dust collection box 3 supports the user to take it out upward and install it downward into the mounting cavity 120, which is more convenient for the user to operate. The first traveling wheel 41, the second traveling 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 the left and right direction or the front and back direction. Correspondingly, the disassembly and assembly direction of the dust collection box 3 relative to the mounting base 12 is the left and right direction or the front and back direction, which is not uniquely limited here.

[0038] Furthermore, the cleaning device 100 further includes a face cover 13. The face cover 13 is arranged on the main body 1 and covers the mounting cavity 120, thereby accommodating the dust collection box 3 inside the mounting cavity 120 of the main body 1. On the one hand, the cooperation between the face cover 13 and the main body 1 can position the dust collection box 3, preventing the dust collection box 3 from being jolted during the operation of the cleaning device 100, resulting in the dust collection box 3 detaching from the mounting cavity 120 and then synchronously detaching from structures such as the suction assembly 2, thus affecting the normal operation of the cleaning device 100. On the other hand, the face cover 13 can prevent dust and other impurities from falling onto the main body 1 and the dust collection box 3.

[0039] It is worth mentioning that, in this embodiment, the face cover 13 is detachably connected to the main body 1. When the user needs to take out the dust collection box 3, the face cover 13 can be taken out first, and then the dust collection box 3 can be taken out. The connection method between the face cover 13 and the main body 1 can be magnetic connection, snap connection, etc. In some embodiments, the face cover 13 can also be designed such that a part is fixedly connected to the main body 1, such as bonding, screw connection, etc., and the other part is rotatable relative to the main body 1. When the user needs to take out the dust collection box 3, first lift the rotatable part of the face cover 13, and then take out the dust collection box 3.

[0040] To be able to disassemble and clean the dust collection box 3 more conveniently, please refer to Figure 5 , Figure 5 is Figure 2 a schematic structural diagram of another embodiment of the cleaning device described in. In other embodiments, an opening window 130 is provided on the face cover 13. The opening window 130 is used to avoid the dust collection box 3. The dust collection box 3 is installed in the mounting cavity 120 through the opening window 130. By providing the opening window 130, the dust collection box 3 is completely accommodated in the main body 1, and it is also convenient to take the dust collection box 3. In this embodiment, the face 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 embodiments and will not be elaborated here.

[0041] As needed, the cleaning device 100 can be configured to include a cleaning module, for example: including at least any 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.

[0042] 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.

[0043] 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.

[0044] Since the cleaning device 100 needs to perform map building, positioning, and avoid some obstacles on the working surface during actual use, such as furniture, living things, etc., in some embodiments, the cleaning device 100 further includes an obstacle avoidance sensing device 6. Along the advancing 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 traveling route of the main body 1, and the cleaning device 100 plans the traveling route or determines the cleaning strategy, etc. based on the detection result of the obstacle avoidance sensing device 6.

[0045] Furthermore, in order to expand the detection range of the obstacle avoidance sensing device 6, the obstacle avoidance sensing device 6 protrudes from the top of the main body 1 and can achieve detection within a 360° range. Among them, the obstacle avoidance sensing device 6 can be a lidar or other sensing devices, such as a TOF sensor, a camera, an infrared sensor, etc. In other embodiments, the obstacle avoidance sensing device 6 can also be installed inside the main body 1, and an avoidance window corresponding to the obstacle avoidance sensing device 6 is opened on the main body 1.

[0046] In this embodiment, the dust collection box 3 is located behind the obstacle avoidance sensing device 6 to ensure the rationality of the center of gravity distribution of the cleaning device 100, avoid the center of gravity of the cleaning device 100 being too far forward, and also avoid the dust brought out during the disassembly and assembly of the dust collection box 3 from polluting the obstacle avoidance sensing device 6.

[0047] In order to quickly and smoothly enter the dust and debris cleaned by the cleaning module into the dust collection box 3, the above-mentioned cleaning device 100 further includes an air suction component 2 for generating a suction airflow. The air suction component 2 is installed on the main body 1 and is connected to the dust collection box 3. Specifically, the dust collection box 3 includes a box body 31 and a cyclone separator 32 provided in the box body 31. The dust outlet 312 and the dust inlet 311 are both provided on the box body 31. And, the box body is further provided with an air suction port 313, and the air suction end 211 of the air suction component 2 is communicated with the air suction port 313. When the cleaning device 100 is working normally on the working surface, the air suction component 2 starts to work. The suction airflow generated by the air suction component 2 carries the garbage and enters the box body 31 from the dust inlet 311, and then passes through the cyclone separator 32. Garbage, finer dust, etc. remain in the box body 31 under the action of gravity and the cyclone separator 32. The suction airflow flows out of the dust collection box 3 from the air suction port 313.

[0048] To ensure the suction separation effect, the height of the dust inlet 311 is lower than that of the suction port 313, thereby increasing the suction air flow path of the suction assembly 2. This causes the garbage that enters the box body 31 from the dust inlet 311 to rise while rotating as it passes through the cyclone separation of the cyclone separator 32 with the suction air flow. At this time, the garbage in the suction air flow falls into the box body 31 under the combined action of gravity and collision separation with the cyclone separator 32; while the suction air flow does not carry dust, preventing the dust from entering the suction port 313 and further affecting or damaging the normal operation of the suction assembly 2 and even the entire cleaning device 100.

[0049] In some embodiments, when there is a large amount of garbage inside the cleaning device 100, the cleaning effect may be poor due to insufficient suction. The suction port 313 can be multiple, such as at least two. Correspondingly, the suction assembly 2 is also at least two. Each suction assembly 2 is arranged on the main body 1, and the suction end 211 of each suction assembly 2 is communicated with the corresponding suction port 313. On the one hand, setting multiple suction ports 313 and the corresponding multiple suction assemblies 2 can solve the problem of insufficient air volume of the suction assembly 2 when the cleaning device 100 is cleaning on the carpet or when there are large-sized garbage and sundries on the ground. By using at least two suction assemblies 2, the air volume provided by the suction assembly 2 can be doubled, further enhancing the cleaning ability of the cleaning device 100. On the other hand, when using at least two suction assemblies 2, compared with the case of only using one suction assembly 2, the two suction 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 some other embodiments, when both a dry cleaning module and a wet cleaning module 5 are provided, the wet cleaning module 5 also has two, and are respectively arranged at both ends of the two suction assemblies 2 to completely cover the area adsorbed by the roller brush assembly 15, achieving a larger area of mopping and washing in one pass. Of course, in some embodiments, only one set of suction assemblies 2 can also be used.

[0050] More preferably, at least two suction components 2 are arranged such that the directions in which the suction airflows generated by each suction component 2 flow out of the dust collection box 3 are all different, that is, these suction components 2 are located in different directions of the dust collection box 3, making the utilization of the spatial structure of the suction components 2 in the entire cleaning device 100 more reasonable. While avoiding interference between the suction airflows, it can reduce the noise of the cleaning device 100. For example, the suction components 2 are arranged at intervals, and the centerlines connecting each suction component 2 to the corresponding suction port 313 are arranged in a crossed manner. More specifically, along the forward direction of the main body 1, each suction component 2 is arranged behind the dust collection box 3, ensuring that when the suction component 2 is working, the direction of driving the dust into the dust collection box 3 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 directly behind, left rear, or right rear. In some other embodiments, according to the actual structure arrangement inside the cleaning device 100, at least one of the at least two suction components 2 can be arranged on the left or right side of the dust collection box 3, or the two suction components 2 can be respectively arranged on the left or right side of the dust collection box 3, leaving sufficient installation space for other structures inside the cleaning device 100.

[0051] Please continue to refer to Figure 7 , in some embodiments, an air flow chamber 316 communicating with the suction port 313 is further provided inside the box body 31. The air flow chamber is located downstream of the cyclone separator 32, and the suction port 313 communicates with the air flow chamber 316. When the cleaning device 100 is working, each suction component 2 works, and the suction airflow of each suction component 2 enters the air flow chamber 316 after entering the cyclone separator 32 and then flows out from the suction port 313. At this time, the garbage that enters the dust collection box 3 along with the suction airflow is separated and collected in the cyclone separator 32. The setting of the air flow chamber 316 can make the suction airflow flow more smoothly.

[0052] In order to avoid interference between the suction airflows of the suction components 2, resulting in turbulence, in some specific embodiments, please continue to refer to Figure 6 , a partition 317 is further provided inside the air flow chamber 316. The partition 317 divides the air flow chamber 316 into at least two sub-air flow chambers 3160, and the sub-air flow chambers 3160 communicate with the suction ports 313 one by one. The number of partitions 317 is related to the number of suction components 2. It can be understood that when two suction components 2 are provided, the partition 317 is one, dividing the air flow chamber 316 into two sub-air flow chambers 3160, each sub-air flow chamber 3160 communicates with one suction port 313, and each suction port 313 is connected to one suction component 2. Therefore, the suction airflows generated by the operation of the suction components 2 flow in their respective sub-air flow chambers 3160 without interfering with each other in the air flow chamber 316, further improving the suction effect of the suction components 2.

[0053] In order to prevent garbage and impurities from entering the suction component 2 along with the suction air flow, please refer to Figure 9 and Figure 10 , Figure 9 yes Figure 2 A structural diagram of a connection method between the dust collecting box and the suction component; Figure 10 yes Figure 9 Schematic diagram of the structure of an embodiment of the suction assembly described in . 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 further filters the airflow flowing out of the airflow chamber 316 and processed by the dust collection box 3 to prevent fine dust from entering the interior of the suction assembly 2 with the airflow, thereby affecting the normal operation of the suction assembly 2 and further affecting the normal operation of the cleaning device 100.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] In some embodiments, please refer to Figure 10 、 Figure 11 and Figure 12 , Figure 11 yes Figure 10Exploded view of an embodiment of the suction assembly described in Figure 12 is Figure 10 Schematic structural view of an embodiment of the filter element described in . 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 installed on the fixing bracket 221. The fixing bracket 221 is provided with air passing holes 220. The air passing holes 220 are hermetically docked with the suction port 313. The filter element 222 covers the air passing holes 220 and the suction port 313 and is used for filtering the suction air flow flowing through the air passing holes 220 and the suction port 313. The fixing bracket 221 is used for installing the filter element 222 on one hand and hermetically docking with the dust collection box 3 on the other hand, and can avoid the deformation of the filter element 222.

[0058] It can be understood that since the air flow separated and filtered by the dust collection box 3 will not carry large particles of dust inside, in order to ensure the further filtering effect of the filter element 222, in some embodiments, the filtering accuracy range of the filter element 222 is that the purification rate of small dust of 0.1μm - 0.3μm needs to reach 99.998%, further ensuring the effectiveness of the filtering of the suction air flow by the filter element 222.

[0059] It is worth mentioning that in this embodiment, the filter module 22 is arranged outside the dust collection box 3, which can not only simplify the structure of the dust collection box 3, but also avoid directly contacting the inside of the dust collection box 3 and getting hands dirty when the user disassembles and installs the filter module 22. In other embodiments, the filter module 22 can also be arranged inside the dust collection box 3, for example, between the cyclone separator 32 and the air flow chamber 316.

[0060] Furthermore, in some embodiments, each suction assembly 2 further includes a mounting bracket 23. The mounting bracket 23 is connected to the main body 1. The suction fan 21 and the filter module 22 are both installed on the mounting bracket 23. The mounting bracket 23 further includes buffer pads 230. There may be two buffer pads 230. The two buffer pads 230 are respectively installed at both ends of the suction fan 21 and are in contact with the mounting bracket 23, and are used for shock absorption treatment of the suction fan 21. When the suction fan 21 is working, the buffer pads 230 can absorb part of the vibration and noise generated by the suction fan 21, thereby improving the use feeling of the entire cleaning device 100.

[0061] Specifically, please continue to refer to Figure 11, the mounting bracket 23 includes a first accommodation cavity 231 and a second accommodation cavity 232, and the mounting bracket 23 abuts against the peripheral wall of the box body 31. The first accommodation cavity 231 covers the suction port 313, and the suction end 211 of the suction fan 21 faces the first accommodation cavity 231. The suction assembly 2 sucks dust and sundries on the working surface such as the house floor into the dust collection box 3 through the suction port 313. The filter module 22 is installed in the first accommodation cavity 231, and the suction fan 21 is installed in the second accommodation cavity 232, so that the filter module 22 can be additionally provided without disturbing the normal operation of the suction fan 21, and further prevent dust and sundries from passing through the suction port 313 along with the air flow when the suction fan 21 sucks the inside of the dust collection box 3.

[0062] Further, please continue to refer to Figure 12 , in some embodiments, the filter module 22 further includes two sealing gaskets 223. One of the sealing gaskets 223 is disposed between the fixing bracket 221 and the inner wall of the first accommodation cavity 231 to stably fix the entire filter module 22 in the first accommodation cavity 231. The other sealing gasket 223 is disposed between the air passing hole 220 and the suction port 313 to achieve fitting and sealing at the suction port 313, and prevent the suction air flow from overflowing from the connection between the filter element 222 and the fixing bracket 221, so that relatively small dust may enter the inside of the cleaning device 100 along the gap at the connection, resulting in dust accumulation, and in severe cases, abnormal noise may occur, affecting the use feeling of the entire cleaning device 100.

[0063] It can be understood that, in order to smoothly discharge the suction air flow generated when the suction fan 21 works from the suction assembly 2, please refer to Figure 1 and Figure 11 , in some embodiments, the mounting bracket 23 is further provided with an exhaust air duct 234. The suction air flow 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 then flows out of the suction assembly 2 through the exhaust air 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 air duct 234 are all installed or integrated on the mounting bracket 23, with a simple structure, and the suction assembly 2 occupies a relatively small space, which can make the overall volume of the cleaning device smaller.

[0064] In order to improve the separation and collection effect of the dust collection box 3 and avoid blockage, please refer to Figure 6 and Figure 7 , Figure 6 is Figure 2 an exploded structural schematic diagram of an embodiment of the dust collection box described in Figure 7 is Figure 6Schematic diagram of the structure of the box described therein. In some embodiments, the cyclone separator 32 is connected to the box 31 to form a first sub-dust collection chamber 33 and a second sub-dust collection chamber 34 that communicate with each other. The dust inlet 311 communicates with the first sub-dust collection chamber 33, and the suction port 313 communicates with the second sub-dust collection chamber 34. The dust outlet 312 communicates with the first sub-dust collection chamber 33 and the second sub-dust collection chamber 34. When the cleaning device 100 is cleaning on the working surface, the suction assembly 2 starts to work. The suction airflow generated by the suction assembly 2 enters the first sub-dust collection chamber 33 from the dust inlet 311, passes through the cyclone separator 32, and flows out from the suction port 313. In the direction of the suction airflow, the first sub-dust collection chamber 33 is located upstream of the second sub-dust collection chamber 34. When the cleaning device 100 of the present application enters the dust into the dust collection box 3, the cyclone separator 32 is used to first filter the garbage with larger sizes and accommodate it in the first sub-dust collection chamber 33; the garbage with smaller particles, such as dust, enters the cyclone separator 32. Due to the internal suction effect of the cyclone separator 32, a cyclone is formed, generating a centrifugal force that causes all the garbage to gather in the center of the cyclone and fall into the second sub-dust collection chamber 34. Finally, the garbage in the first sub-dust collection chamber 33 and the garbage in the second sub-dust collection chamber 34 can be discharged from the dust outlet 312, realizing the collection of garbage with different particle sizes, and avoiding the smaller particles of garbage from clogging in the dust collection box 3 or entering the suction assembly 2 with the airflow, which affects the suction assembly 2. When the cleaning device 100 is docked with the dust collection station 200, the docking port 201 communicates with the dust outlet 312, and the fan 202 in the station works to make the dust collected in the dust collection box 3 flow through the dust outlet 312, the dust collection channel 11, the docking port 201, and the channel 204 into the dust storage chamber 203, realizing the collection and treatment of garbage with different particle sizes.

[0065] Specifically, the cyclone separator 32 includes a filter housing 321 and a cyclone tube group 322. The filter housing 321 is provided on the periphery of the cyclone tube group 322 for preferentially filtering the garbage with larger sizes. The suction airflow enters the cyclone tube group 322 after passing through the filter housing 321 from the first sub-dust collection chamber 33. The first sub-dust collection chamber 33 is used to accommodate the garbage intercepted by the filter housing 321, and the second sub-dust collection chamber 34 is used to accommodate the garbage separated by the cyclone tube group 322, completing the secondary filtration and collection of dust, and further avoiding some dust from entering the suction assembly 2 with the airflow, which affects the suction assembly 2.

[0066] Specifically, please refer to Figure 13 , Figure 13 is Figure 2Schematic structural diagram of another embodiment of the dust collection box described in [reference]. In some embodiments, the box body 31 includes a bottom wall 318 and side walls 319 connected to the bottom wall 318. The bottom wall 318 and the side walls 319 form a receiving cavity 310, and the cyclone separator 32 is accommodated in the receiving cavity 310. The filter housing 321 divides the receiving cavity 310 into a first sub-dust collection cavity 33 and a second sub-dust collection cavity 34. For example, in one example, the filter housing 321 is installed in the receiving cavity 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 collection cavity 33 and the second sub-dust collection cavity 34 are respectively located on both sides of the filter housing 321, and are respectively surrounded by the bottom wall 318, the side walls 319, and the filter housing 321. When the filter housing 321 is cylindrical, a first sub-dust collection cavity 33 is formed between the bottom wall 318, the side walls 319, and the outer wall of the filter housing 321; a second sub-dust collection cavity 34 is formed between the bottom wall 318 and the inner wall of the filter housing 321. Of course, it can be understood that when the filter housing 321 is cylindrical, it can be a cylindrical tube or a cylindrical tube of other shapes.

[0067] Specifically in this embodiment, the first sub-dust collection cavity 33 is arranged to surround the second sub-dust collection cavity 34. Specifically, the second sub-dust collection cavity 34 is located inside the first sub-dust collection cavity 33.

[0068] More preferably, in order to ensure both the dust separation efficiency of the filter housing 321 and the durability of the filter housing 321, please refer to Figure 6 , in some embodiments, the filter housing 321 is in the shape of an annular cylinder. Along the direction perpendicular to the gravity direction, the cross-section of the receiving cavity 310 is circular, the cross-section of the filter housing 321 is circular-ring-shaped, the filter housing 321 is concentrically arranged in the receiving cavity 310, and the first sub-dust collection cavity 33 is arranged to surround the second sub-dust collection cavity 34. Such an arrangement can make the suction air flow along the inner wall of the receiving cavity 310, improving the centrifugal separation effect of large particle garbage and the suction air flow. And after the suction air flow enters the cyclone separator 32, under the action of the cyclone separator 32, the separation effect of small particle garbage and the suction air flow can be ensured.

[0069] In order to enhance the speed and efficiency of subsequent discharging of the dust inside the dust collection box 3 from the dust collection box 3, the dust outlet 312 on the dust collection box 3 can be provided with one or multiple. The following will classify and describe in detail the setting structure of the dust outlet 312 on the dust collection box 3:

[0070] Embodiment 1:

[0071] Please refer to Figure 13 and Figure 14 , Figure 14 in Figure 2Cross-sectional view of another embodiment of the dust collection box described in [the reference]. In the first embodiment, there is one dust outlet 312 of the dust collection box 3. At this time, some of the dust outlets 312 communicate with the first sub-dust collection cavity 33, and some of the dust outlets 312 communicate with the second sub-dust collection cavity 34. That is to say, the first sub-dust collection cavity 33 and the second sub-dust collection cavity 34 share one dust outlet 312. According to the arrangement of the first sub-dust collection cavity 33 and the second sub-dust collection cavity 34, the dust outlet 312 is provided on the bottom wall 318 or the side wall 319. At this time, the garbage collected in the first sub-dust collection cavity 33 and the second sub-dust collection cavity 34 is discharged through the dust outlet 312 simultaneously when the dust collection box 3 needs to be emptied. For example, in Figure 6 , Figure 13 and Figure 14 In the illustrated embodiment, 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 collection cavity 34, and the process channel extends to communicate with the dust outlet 312. For the embodiment in which both the first sub-dust collection cavity 33 and the second sub-dust collection cavity 34 are 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.

[0072] When the dust outlet 312 is provided on the side wall 319, taking Figure 14 as a reference, the inner wall surface of the receiving cavity 310 includes at least a partial arc surface 3101. The dust outlet 312 on the side wall 319 is provided at the arc surface 3101, and the opening direction of the dust outlet 312 is tangent to the arc 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 arc surface 3101 with the airflow.

[0073] It can be understood that in order to prevent the garbage collected in the dust collection box 3 from spilling out of the dust collection box 3 due to the normal operation of the cleaning device 100 or the collision when encountering an obstacle during the normal operation of the cleaning device 100, please refer to Figure 7 and Figure 8 , Figure 8 in Figure 6The cross-sectional view of the dust collection box described in [reference]. In this embodiment, the dust collection box 3 further includes a baffle door 314, which is pivotally connected to the box body 31. The baffle door 314 is used to cover or open the dust outlet 312. When the cleaning device 100 is detached from the dust collection station 200 or the in-station fan 202 is not working, the baffle door 314 covers the dust outlet 312. When the cleaning device 100 is docked with the dust collection station 200 and it is necessary to discharge the garbage collected in the first sub-dust collection cavity 33 and the second sub-dust collection cavity 34, the suction force generated by the operation of the in-station fan 202 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 in-station fan 202. It is not difficult to understand that when the dust collection operation of the cleaning device 100 by the dust collection station 200 is completed, the baffle door 314 returns to the state of closing the dust outlet 312 again. The baffle door 314 can be reset under the action of a spring (not shown in the figure) or can be made of an elastic material itself. Of course, in other embodiments, the baffle door 314 can also be set in an electric form, that is, it is driven by a motor (not shown in the figure) to move, so that the baffle door 314 opens or closes the dust outlet 312.

[0074] Further, in this embodiment, please refer to Figure 15 , Figure 15 FIG. [reference number] is a schematic structural diagram of an embodiment of the dust collection channel in Embodiment 1 proposed in the present application. The dust collection channel 11 of the main body 1 is one, provided with an inlet port 111 and an outlet port 112. Both the inlet port 111 and the outlet port 112 are one. The inlet port 111 is docked with the dust outlet 312, and the outlet port 112 is used to dock with the docking port 201 of the dust collection station 200. When the dust collection station 200 performs the dust collection operation on the cleaning device, the garbage inside the first sub-dust collection cavity 33 and the second sub-dust collection cavity 34 enters the dust collection channel 11 through the same dust outlet 312, and then enters the dust storage cavity 203 through the docking port 201 and the channel 204. At this time, since there is only one outlet port 112, only one docking port 201 of the dust collection station 200 is also provided.

[0075] Embodiment 2:

[0076] In Embodiment 2, please refer to Figure 16 and Figure 17 , Figure 16 FIG. [reference number] is a schematic structural diagram of an embodiment of the dust collection channel in Embodiment 2 proposed in the present application; Figure 17It is a schematic structural diagram of another embodiment of the dust collection channel in Embodiment 2 proposed in this application. There are two dust outlets 312, including a first dust outlet 3121 and a second dust outlet 3122 arranged at intervals. The first dust outlet 3121 communicates with the first sub-dust collection cavity 33, and the second dust outlet 3122 communicates with the second sub-dust collection cavity 34, ensuring that the garbage with different weights and sizes in the first sub-dust collection cavity 33 and the second sub-dust collection cavity 34 can be discharged through different dust outlets 312. By separately arranging the first dust outlet 3121 and the second dust outlet 3122, it is ensured that when the fan 202 in the station is working, the garbage in the first sub-dust collection cavity 33 and the second sub-dust collection cavity 34 can leave the dust collection box 3 from the appropriate dust outlet 312.

[0077] Furthermore, the first dust outlet 3121 and the second dust outlet 3122 can be both arranged on the bottom wall 318 at the same time, or both arranged on the side wall 319 at the same time. The first dust outlet 3121 and the second dust outlet 3122 can also be one arranged on the side wall 319 and the other arranged on the bottom wall 318. As Figure 7 shown, preferably, considering that the first sub-dust collection cavity 33 stores larger particle garbage, the first dust outlet 3121 can be arranged on the side wall 319, and since the first sub-dust collection cavity 33 surrounds the second sub-dust collection cavity 34, the second dust outlet 3122 can be arranged on the bottom wall 318. Such a structure is not only simple but also enables the larger particle garbage to smoothly leave the dust collection box 3 from the first dust outlet 3121, and the smaller particle garbage to smoothly leave the dust collection box 3 from the second dust outlet 3122.

[0078] Similarly, similar to Embodiment 1, for the first dust outlet 3121 and the second dust outlet 3122 both arranged on the bottom wall 318 or the side wall 319, in order to prevent the garbage from spilling 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.

[0079] It can be understood that in this Embodiment 2, the first dust outlet 3121 and the second dust outlet 3122 are arranged at intervals. As Figure 16As shown, in order to avoid problems such as an imperfect closing of a baffle door 314 or an excessive opening suction requirement caused by too large a size of the required baffle door 314, which may lead to issues where the power of the in-station fan 202 cannot 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. 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 it is necessary to discharge the garbage collected in the first sub-dust collection cavity 33 and the second sub-dust collection cavity 34, the suction force generated by the operation of the in-station fan 202 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 cavity 33 can enter the dust collection channel 11 from the first dust outlet 3121 and the garbage in the second sub-dust collection cavity 34 can enter the dust collection channel 11 from the second dust outlet 3122, and under the action of the in-station fan 202, it enters the dust collection station 200.

[0080] Similarly, when one of the first dust outlet 3121 and the second dust outlet 3122 is provided on the side wall 319, the same as in the first embodiment, the inner wall surface of the receiving cavity 310 includes at least a partial arc surface 3101. The first dust outlet 3121 and / or the second dust outlet 3122 provided on the side wall 319 is / are provided at the arc surface 3101, and the opening direction of the first dust outlet 3121 and / or the second dust outlet 3122 is tangent to the arc surface 3101. Also, the opening and closing manners of the baffle door, the first baffle door, and the second baffle door are the same as those in the first embodiment and will not be elaborated here.

[0081] It can be understood that the above second embodiment is only described with two dust outlets. In practice, the number of dust outlets 312 of the cleaning device 100 can also be set to more than 2. When multiple dust outlets 312 are provided, there is at least one first dust outlet 3121 communicating with the first sub-dust collection cavity 33, and there is also at least one second dust outlet 3122 communicating with the second sub-dust collection cavity 34. There can also be multiple first dust outlets 3121, multiple second dust outlets 3122, and multiple baffle doors 314 for covering or opening the multiple dust outlets 312. Their specific structures can refer to those set in the second embodiment and will not be elaborated here.

[0082] In this second embodiment, the dust collection channel 11 of the main body 1 can be provided with one dust collection channel 11 or multiple dust collection channels 11 in various setting manners. The specific structures are as follows:

[0083] When there is one dust collection channel 11, 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 docking interfaces 201 of the dust collection station 200 is the same as the number of dust outlet ports 112, which is also one. Among them, in one embodiment, the number of dust inlet ports 111 is the same as the number of dust outlet ports 312. Since Embodiment 2 takes two dust outlet ports 312 as an example, correspondingly, the dust inlet ports 111 are described with two as an example. When there are two dust inlet ports 111, the two dust inlet ports 111 are respectively docked with the first dust outlet 3121 and the second dust outlet 3122. The two dust inlet ports 111 are communicated with the same dust outlet port 112, and the dust outlet port 112 is used to dock with the docking interface 201 of the dust collection station 200. Under the action of the internal fan 202 of the station, the garbage in the first sub-dust collection chamber 33 enters the dust collection channel 11 through the first dust outlet 3121 and the corresponding dust inlet port 111, and the garbage in the second sub-dust collection chamber 34 enters the dust collection channel 11 through the second dust outlet 3122 and the corresponding dust inlet port 111. The garbage entering the dust collection channel 11 then enters the dust storage chamber 203 through the same dust outlet port 112 and the docking interface 201.

[0084] In other embodiments, such as Figure 17 shown, the number of dust inlet ports 111 can also be less than the number of dust outlet ports 312. For example, the number of dust inlet ports 111 can be set to only one, and the inner diameter of the dust inlet port 111 is larger, which can surround and cover all dust outlet ports 312, such as the first dust outlet 3121 and the second dust outlet 3122. Or, the number of dust inlet ports 111 is 2, and the number of dust outlet ports 312 is 3, then two of the dust outlet ports 312 share one dust inlet port 111.

[0085] When there are multiple dust collection channels 11, the dust collection channels 11 can be designed to have the same number as the dust outlet ports 312. Since Embodiment 2 takes two dust outlet ports 312 as an example, correspondingly, the dust collection channels 11 are described with two as an example. At this time, each dust collection channel 11 is provided with one dust inlet port 111 and one dust outlet port 112, and each dust inlet port 111 is communicated with the corresponding dust outlet 312. That is to say, 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 another dust collection channel 11 through the second dust outlet 3122.

[0086] Regarding the docking interface 201 of the dust collection station 200, the number of docking interfaces 201 can be the same as the number of dust outlet ports 112, or less than the number of dust outlet ports 112. When the number of docking interfaces 201 is the same as the number of dust outlet ports 112, each dust outlet port 112 is used to dock one docking interface 201. When the number of docking interfaces 201 is less than the number of dust outlet ports 112, at least one docking interface 201 is used to dock at least two dust outlet ports 112 simultaneously.

[0087] Since the larger-sized garbage is accommodated in the first sub-dust collection chamber 33, in order to completely collect these large-particle garbage into the dust collection station 200, in some embodiments, the suction assembly 2 can be turned on as needed after the station fan 202 has been operating for a first preset duration and work together with the station fan 202 for a second preset duration. Figure 7 Taking the illustrated embodiment as an example for specific description, that is, the first sub-dust collection chamber 33 is correspondingly provided with a first baffle door 3141, and the second sub-dust collection chamber 34 is correspondingly provided with a second baffle door 3142. During the first preset duration when the station fan 202 is operating, both the first baffle door 3141 and the second baffle door 3142 are in an open state under the adsorption effect of the station fan 202. During this period, at least the small-particle garbage in the second sub-dust collection chamber 34 can quickly enter the dust collection 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 all be used to suck the garbage in the first sub-dust collection chamber 33, thereby enabling the garbage in the first sub-dust collection chamber 33 to completely enter the dust collection station 200. Specifically, the cleaning system further includes a controller (not shown in the figure). The controller is connected to the station fan 202 and the suction assembly 2, and the controller controls the suction fan 21 and the station fan 202 to work according to the above first preset duration and second preset duration according to preset conditions, thereby ensuring that the garbage in the dust collection box 3 can be completely cleaned.

[0088] In order to facilitate the disassembly and replacement of the cyclone separator 32, in some embodiments, the box body 31 of the dust collection box 3 further includes a cover body 315 disposed opposite to the bottom wall 318 and detachably connected to the side wall 319. The cyclone separator 32 is detachably connected to the cover body 315, and the dust inlet 311 is provided on the side wall 319. Among them, the airflow chamber 316, the partition 317, and the suction port 313 are all provided on the cover body 315 to ensure that the suction airflow inside the dust collection box 3 during the normal operation of the suction assembly 2 can flow for a relatively long distance. When the user removes the cover body 315, the cyclone separator 32 will be removed together, facilitating the user to directly clean the inner wall of the accommodation chamber 310. When it is necessary to clean the cyclone separator 32, the cyclone separator 32 can be removed from the cover body 315 again.

[0089] More specifically, the cyclone tube group 322 includes a plurality of conical tubes 3220, and each conical tube 3220 is installed on the cover 315. Each conical tube 3220 is a hollow tube, so that the opposite ends of each conical tube 3220 communicate with the second sub-dust collection chamber 34 and the corresponding sub-air flow chamber 3160 respectively. Moreover, the inner diameter of each conical tube 3220 facing the sub-air flow chamber 3160 is larger than the inner diameter facing the second sub-dust collection chamber 34. The axial direction of each conical tube 3220 and the center line of the second sub-dust collection chamber 34 are both parallel to the direction of gravity. Among them, the air flow carrying smaller-sized garbage after being filtered once by the filter housing 321 enters different conical tubes 3220 respectively, and the plurality of conical tubes 3220 perform secondary separation synchronously. On the one hand, it speeds up the separation speed of the garbage from the suction air flow. On the other hand, when a cyclone effect is generated inside the cyclone tube group 322, compared with the situation where all the garbage is separated in a single conical tube 3220, it can avoid some dust not being able to rotate along the side wall of the conical tube 3220 in time along with the cyclone when the cyclone effect occurs, and then entering the suction assembly 2 along with the suction air flow, which affects the normal operation of the suction assembly 2.

[0090] In addition, in order to fix the cyclone tube group 322 more firmly inside the dust collection box 3, please continue to refer to Figure 6 and Figure 8 , in some embodiments, the dust collection box 3 further includes a connecting bracket 35. The first connecting bracket 351 is fixed to the cover 315, and the cyclone tube group 322 is installed on the first connecting bracket 351, so as to avoid the cyclone tube group 322 from shaking due to the impact of the air flow on the side wall of the cyclone tube group 322 when a cyclone effect is generated inside the cyclone tube group 322, which affects the internal cyclone effect, resulting in that the dust heavier than the air flow cannot be completely separated and enters the air flow chamber 316 along with the air flow, thereby affecting the normal function of the entire dust collection box 3. A hollow air inlet pipe 350 is provided on the side of the first connecting bracket 351 facing away from the cover 315. Each hollow air inlet pipe 350 is located inside the corresponding cyclone tube group 322, and each hollow air inlet pipe 350 communicates the air flow chamber 316 and the corresponding cyclone tube group 322. The relatively light air flow separated inside the cyclone tube group 322 due to the cyclone effect is sent into the air flow chamber 316 through the hollow air inlet pipe 350.

[0091] On the other hand, the dust collection box 3 further includes a second connecting bracket 352. The second connecting bracket 352 is also used to support the cyclone tube group 322, so that the end of the cyclone tube group 322 away from the cover 315 is clamped on the second connecting bracket 352.

[0092] The dust collection box 3 further includes a third connecting bracket 353 which supports and connects the filter housing 321, stably fixing the filter housing 321 on the second connecting bracket 352 and the cover body 315 to prevent the filter housing 321 from shaking under the action of air flow. Additionally, in Figure 8 the illustrated embodiment, the third connecting bracket 353 and the bottom wall are butted to enclose a part of the second sub-dust collection chamber 34. In other embodiments, the third connecting bracket 353 can also be omitted, and the filter housing 321 can be directly butted with the bottom wall to enclose the second sub-dust collection chamber 34.
