Description

Technical Field

[0001] This invention relates to the field of cleaning machine technology, and in particular to a dust box structure, a sweeper, a cleaning system, and a dust collection method. Background Technology

[0002] With the booming development of the smart cleaning industry, more and more robotic vacuum cleaners are equipped with all-purpose base stations to reduce the frequency of users emptying trash. However, due to the height limitations of existing traditional roller-type robotic vacuum cleaners, their dust collection channels often pass through the top of the roller. This results in a complex path that crosses the upper surface of the roller between the bottom of the dust box and the dust collection port of the base station. Under this structure, when the base station is performing dust collection, the airflow is obstructed by the roller, and it is impossible to form an effective negative pressure adsorption. This makes it easy for a large amount of dust and garbage to remain at the bottom and corners of the dust box. This not only affects the cleaning effect of a single cleaning, but also may breed bacteria and produce odors in the long run, reducing the cleaning performance and service life of the robotic vacuum cleaner and failing to meet users' expectations for efficient cleaning. Summary of the Invention

[0003] The main objective of this invention is to provide a dust box structure, a sweeper, a cleaning system, and a dust collection method. The aim is to solve the technical problem that existing traditional roller sweepers require the dust collection channel to cross the upper surface of the roller, which obstructs airflow during dust collection, prevents the formation of effective negative pressure adsorption, and leaves dust and debris still at the bottom and corners of the dust box, resulting in poor cleaning performance and the inability to achieve efficient cleaning.

[0004] To achieve the above-mentioned objectives, the first aspect of the present invention proposes a dust box structure for connecting to the outside world, including a host dust suction device, a host dust collection device, a host air duct module, and a host dust outlet channel.

[0005] The main unit dust collection device is connected to the main unit air duct module and the main unit dust outlet channel respectively, and the main unit air duct module and the main unit dust outlet channel are arranged opposite to each other. The main unit dust outlet channel is located above the roller of the sweeper, and the dust outlet of the main unit dust outlet channel at the end away from the main unit dust collection device is located on the side of the tail of the sweeper.

[0006] The main unit air duct module includes a main unit air outlet duct and a main unit air inlet duct corresponding to the main unit air outlet duct. The main unit dust collection device is connected between the main unit air outlet duct and the main unit dust collection device. The main unit dust collection device is used to provide the main unit dust collection airflow.

[0007] During the dust removal process, the base station external airflow of the dust collection base station flows into the host dust collection device from the host air outlet channel and the host air inlet channel to form a circulating turbulent flow, or the host dust suction airflow flows into the host dust collection device from the host air inlet channel through the reflector wall of the dust collection base station to form a circulating turbulent flow, which cooperates with the base station dust suction airflow of the dust collection base station to collect dust through the host dust outlet channel.

[0008] Furthermore, the main unit dust collection device includes a dust storage bin and a filter assembly disposed on the dust storage bin. The dust storage bin is connected to the filter assembly. The dust storage bin is provided with a dust bin air inlet that is connected to the main unit air inlet channel. The filter assembly is provided with a filter air outlet that is connected to the main unit air outlet channel. The filter air outlet and the dust bin air inlet are located on the same side and are arranged vertically.

[0009] Furthermore, the dust storage bin has a dust outlet on the side opposite to the dust bin air inlet that is connected to the dust outlet channel of the main unit, and an inclined dust suction port on the side adjacent to the dust bin air inlet. The bottoms of the dust outlet and the dust suction port are at the same designated height to the bottom of the dust storage bin.

[0010] Furthermore, the main unit dust collection device also includes an air inlet baffle and an air outlet baffle. The air inlet baffle is rotatably connected to the inner side of the air inlet of the dust bin via a connecting rod. The air inlet baffle is used to control the communication state between the main unit air inlet channel and the dust storage bin. The air outlet baffle is rotatably connected to the outer side of the dust outlet. The air outlet baffle is used to control the communication state between the main unit dust outlet channel and the dust storage bin. During the dust discharge process, the air inlet baffle opens towards the inside of the dust storage bin, and the air outlet baffle opens towards the outside of the dust storage bin. During the dust suction process, both the air inlet baffle and the air outlet baffle are closed.

[0011] Furthermore, the filter assembly includes a filter support frame, a filter body, and a cover plate. The filter support frame is disposed on the top of the dust storage bin. The filter body is disposed inside the filter support frame to connect the dust storage bin and the filter outlet on the filter support frame. The cover plate is disposed on the side of the filter body away from the dust storage bin. One side of the cover plate is rotatably connected to the filter support frame, and the opposite side of the cover plate is snap-fitted to the filter bracket.

[0012] Furthermore, the main dust collection device includes a main body, a main support frame, and a main connection plate. The main connection plate is connected to the dust storage bin and the filter support frame respectively. The main support frame is disposed between the main body and the main connection plate. The main connection plate is provided with a connecting plate air inlet communicating with the dust bin air inlet, and an air inlet buffer space is formed between the main connection plate and the dust storage bin. The main connection plate is also provided with a connecting plate air outlet communicating with the filter air outlet, and an air outlet buffer space is formed between the main connection plate and the main support frame.

[0013] Furthermore, the main unit air inlet channel includes a first air inlet channel and a second air inlet channel connected to the first air inlet channel. The first air inlet channel is isolated from the main unit air outlet channel by a partition plate. The second air inlet channel includes a first bend, a second bend, and a third bend. The first bend is connected to the end of the first air inlet channel near the dust collection device of the main unit. The second bend is obliquely connected to the end of the first bend away from the first air inlet channel. The third bend is connected to the end of the second bend away from the first bend, and the third bend is in contact with the main unit support frame and the main unit connecting plate, respectively.

[0014] A second aspect of the present invention also provides a sweeping machine, including the dust box structure described in any of the above embodiments, and a sweeping machine body, wherein the dust box structure is disposed within the sweeping machine body.

[0015] A third aspect of the present invention also proposes a cleaning system, including the sweeper described in the above embodiments, and a dust collection base station, wherein the dust collection base station includes a base station body, and a base station fan, a base station dust box, a base station dust collection channel and a base station blowing channel disposed within the base station body;

[0016] The base station fan is mounted on the base station dust box, the base station dust collection channel is connected to the base station dust box, and the base station dust collection channel corresponds to the dust outlet channel of the host unit;

[0017] The base station air blowing channel is connected to the base station fan, and the base station air blowing channel corresponds to the host air duct module. A reflective wall is provided at the end of the base station air blowing channel away from the base station fan. The reflective wall is used to control the connection state between the base station air blowing channel and the host air duct module.

[0018] A fourth aspect of the present invention also provides a dust collection method for a cleaning system, comprising the cleaning system described in the above embodiments, and further comprising:

[0019] Move the sweeper to the interface of the dust collection base station, so that the dust collection channel of the base station is connected to the dust outlet channel of the host, and the air blowing channel of the base station is connected to the air duct module of the host.

[0020] Determine whether the reflective wall connects the base station air blowing channel to the host air duct module;

[0021] If so, the host dust collection device stops operating, the base station fan starts operating, and the base station external airflow generated by the base station fan flows into the host dust collection device through the base station blowing channel, the host air outlet channel and the host air inlet channel respectively to form a circulating turbulent flow, and the dust collection airflow of the base station draws the material to be collected in the host dust collection device into the base station dust box through the host dust outlet channel and the base station dust collection channel;

[0022] If not, the main unit dust collection device starts operating first. The main unit dust collection airflow generated by the main unit dust collection device is reflected by the reflective wall and flows into the main unit dust collection device through the main unit air inlet channel to form a circulating turbulent flow. Then, the base station fan starts operating and sucks the object to be collected in the main unit dust collection device into the base station dust box through the base station dust outlet channel and the base station dust collection channel via the base station dust collection airflow.

[0023] Beneficial effects:

[0024] This invention discloses a dust collection station structure for connecting to the outside environment, comprising a main unit dust collection device, a main unit dust collection device, a main unit air duct module, and a main unit dust outlet channel. The main unit dust collection device is connected to both the main unit air duct module and the main unit dust outlet channel, and the main unit air duct module and the main unit dust outlet channel are arranged opposite each other. The main unit dust outlet channel is located above the roller of the sweeper, and the dust outlet of the main unit dust outlet channel at the end furthest from the main unit dust collection device is located on the side of the rear of the sweeper. The main unit air duct module includes a main unit air outlet channel and a connection to the main unit air outlet channel. The corresponding main unit air inlet channel is connected between the main unit air outlet channel and the main unit dust collection device. The main unit air inlet channel provides the main unit's suction airflow. During dust removal, the base station's external airflow flows into the main unit dust collection device from the main unit air outlet channel and the main unit air inlet channel, forming a circulating turbulent flow. Alternatively, the main unit's suction airflow flows into the main unit dust collection device from the main unit air inlet channel via the reflector wall of the dust collection base, forming a circulating turbulent flow. This turbulent flow, combined with the base station's suction airflow, collects dust through the main unit's dust outlet channel. Therefore, by creating a circulating turbulent flow within the main unit dust collection device, the airflow obstruction problem in traditional structures is overcome, allowing the dust and debris in the dust box to be fully agitated and no longer deposited at the bottom and corners. This makes it easier for the suction airflow from the dust collection base to be drawn into the base station dust box through the main unit's dust outlet channel, greatly improving the base station's dust collection efficiency and achieving highly efficient cleaning by the sweeper.

[0050] Reference Figures 1-10 This embodiment provides a dust box structure 100 for connecting a dust collection base station 300 to the outside world, including a host dust suction device 1, a host dust collection device 2, a host air duct module 3, and a host dust outlet channel 4.

[0051] The main unit dust collection device 2 is connected to the main unit air duct module 3 and the main unit dust outlet channel 4 respectively, and the main unit air duct module 3 and the main unit dust outlet channel 4 are arranged opposite to each other. The main unit dust outlet channel 4 is located above the roller of the sweeper 200, and the dust outlet of the main unit dust outlet channel 4 at the end away from the main unit dust collection device 2 is located on the side of the tail of the sweeper 200.

[0052] The main unit air duct module 3 includes a main unit air outlet duct 30 and a main unit air inlet duct 31 corresponding to the main unit air outlet duct 30. The main unit dust collection device 1 is connected between the main unit air outlet duct 30 and the main unit dust collection device 2. The main unit dust collection device 1 is used to provide the main unit dust collection airflow.

[0053] During the dust removal process, the base station external airflow of the dust collection base station 300 flows into the host dust collection device 2 from the host air outlet channel 30 and the host air inlet channel 31 to form a circulating turbulent flow, or the host dust suction airflow flows into the host dust collection device 2 from the host air inlet channel 31 via the reflector wall 306 of the dust collection base station 300 to form a circulating turbulent flow, which cooperates with the base station dust suction airflow of the dust collection base station 300 to collect dust through the host dust outlet channel 4.

[0054] In the above embodiments, the dust box structure 100 is used to work in conjunction with the dust collection base station 300 to realize the dust collection function of the sweeper 200. The dust box structure 100 includes a main unit suction device 1, a main unit dust collection device 2, a main unit air duct module 3, and a main unit dust outlet channel 4. The main unit suction device 1 is responsible for generating suction airflow and is the power source for the entire dust collection process. The main unit dust collection device 2 is used to temporarily store dust and other debris collected during the cleaning process. It is connected to the main unit air duct module 3 and the main unit dust outlet channel 4. The main unit air duct module 3 is positioned opposite to the main unit dust outlet duct 4. The main unit air duct module 3 includes a main unit air outlet duct 30 and a main unit air inlet duct 31, which are arranged correspondingly. The main unit dust outlet duct 4 is located above the roller of the sweeper 200, and the dust outlet of the main unit dust outlet duct 4 at the end away from the main unit dust collection device 2 is located on the side of the tail of the sweeper 200, thereby enabling side dust collection when the roller sweeper 200 and the dust collection base station 300 are used together. This guides the dust from the main unit's dust collection device 2 into the dust collection base station 300 channel. The main unit's vacuum cleaner 1 is connected between the main unit's air outlet channel 30 and the main unit's dust collection device 2. The main unit's air inlet channel 31 is mainly used to introduce external airflow into the main unit's dust collection device 2. When the main unit's dust collection device 2 blows air into the main unit's air outlet channel 30, it creates a negative pressure inside the main unit's vacuum cleaner 1, thereby generating an upward suction force within the main unit's vacuum cleaner 1. This suction force helps to suck dust from the ground into the dust box during cleaning. During the process, the airflow from the dust collection base station 300 is divided into two paths, flowing into the dust collection device 2 from the main unit's air outlet channel 30 and the main unit's air inlet channel 31, respectively, forming a circulating turbulent flow. Alternatively, the main unit's suction airflow flows into the dust collection device 2 from the main unit's air inlet channel 31 via the reflector wall 306 of the dust collection base station 300, forming a circulating turbulent flow. The circulating turbulence formed by both paths within the dust collection device 2, combined with the dust collection airflow from the dust collection base station 300, transports dust to the dust collection base station 300 through the main unit's dust outlet channel 4. Therefore, by forming a circulating turbulent flow within the dust collection device 2, the airflow obstruction problem in the traditional structure is broken, allowing the dust and debris in the dust box to be fully agitated, preventing them from accumulating at the bottom and corners. This makes it easier for the dust collection airflow from the dust collection base station 300 to be drawn into the base station dust box 303 through the main unit's dust outlet channel 4, greatly improving the dust collection efficiency of the base station and achieving highly efficient cleaning by the sweeper 200.

[0055] Reference Figures 1-4 In one embodiment, the host dust collection device 2 includes a dust storage bin 20 and a filter assembly 21 disposed on the dust storage bin 20. The dust storage bin 20 is connected to the filter assembly 21. The dust storage bin 20 is provided with a dust bin air inlet 22 that is connected to the host air inlet channel 31. The filter assembly 21 is provided with a filter air outlet 23 that is connected to the host air outlet channel 30. The filter air outlet 23 and the dust bin air inlet 22 are located on the same side and are arranged vertically.

[0056] In the above embodiment, the main dust collection device 2 includes a dust storage bin 20 and a filter assembly 21. The dust storage bin 20 is the main dust storage space, and the filter assembly 21 is installed on top of the dust storage bin 20. The dust storage bin 20 and the filter assembly 21 are connected to each other to achieve air filtration and purification, preventing dust from leaking into the external environment or entering other parts of the sweeper 200. The dust bin air inlet 22 is located on one side of the dust storage bin 20 and is the airflow inlet between the main unit air inlet channel 31 and the dust storage bin 20, allowing external airflow to enter the dust storage bin 20 and participate in circulation. The filter air outlet 23 is located on one side of the filter assembly 21 and is connected to the main unit air outlet channel 30, through which the filtered air is discharged. The filter assembly 21 is installed on the dust storage bin 20. When the filter outlet 23 and the dust bin inlet 22 are located on the same side of the entire main dust collection device 2, and the centers of the filter outlet 23 and the dust bin inlet 22 are on the same central axis. At the same time, the filter outlet 23 is located on the upper side of one side of the entire main dust collection device 2, and the dust bin inlet 22 is located on the lower side of one side of the entire main dust collection device 2. The airflow moves upward, carrying the bottom garbage up with it. The vertical arrangement of the filter outlet 23 and the dust bin inlet 22 helps to form a specific airflow direction, which promotes the air to form a circulating turbulent flow in the dust collection bin 20, thereby effectively stirring the garbage at the bottom and making the garbage at the bottom fully lifted up. This greatly reduces the dust residue at the bottom and corners of the dust collection bin 20 and improves the dust collection effect.

[0057] Reference Figures 1-5 In one embodiment, the dust storage bin 20 has a dust outlet 24 on the side opposite to the dust bin air inlet 22, which is connected to the dust outlet channel 4 of the main unit. The dust storage bin 20 has an inclined suction port 25 on the side adjacent to the dust bin air inlet 22. The bottoms of the dust outlet 24 and the suction port 25 are at the same designated height from the bottom of the dust storage bin 20.

[0058] In the above embodiment, the dust outlet 24 is located on the side opposite to the dust storage bin 20 and the dust bin air inlet 22, that is, the dust outlet 24 and the dust bin air inlet 22 are arranged opposite each other. The dust outlet 24 is the outlet for dust to exit from the dust storage bin 20 and enter the host dust outlet channel 4, and is directly connected to the host dust outlet channel 4 to ensure that the dust can be smoothly transferred to the dust collection base station 300. The suction port 25 is located on the side adjacent to the dust storage bin 20 and the dust bin air inlet 22, and the side of the suction port 25 is inclined towards the inside of the dust storage bin 20, so that the upper space of the dust storage bin 20 is larger and the bottom space of the dust storage bin 20 is smaller, so that the suction port 25 is relatively large relative to the dust storage bin 20. The air inlet 22 is inclined, and its main function is to suck up dust during the sweeping process of the sweeper 200. The bottom of the dust outlet 24 and the suction port 25 are both at the same specified height from the bottom of the dust storage bin 20, so that the bottom space of the dust storage bin 20 has a certain depth of dust storage space. The height setting of the dust outlet 24 allows the garbage raised by the circulating turbulence to be sucked into the base station more efficiently when collecting dust in the base station. The inclined design and height of the suction port 25 ensure that the dust storage bin 20 has sufficient dust storage depth. At the same time, the open inclined structure of the suction port 25 can effectively prevent garbage from leaking from the suction port 25 during the dust collection process in the base station.

[0059] Reference Figures 1-4 In one embodiment, the main unit dust collection device 2 further includes an air inlet baffle 26 and an air outlet baffle 27. The air inlet baffle 26 is rotatably connected to the inner side of the dust bin air inlet 22 via a connecting rod 28. The air inlet baffle 26 is used to control the communication state between the main unit air inlet channel 31 and the dust storage bin 20. The air outlet baffle 27 is rotatably connected to the outer side of the dust outlet 24. The air outlet baffle 27 is used to control the communication state between the main unit dust outlet channel 4 and the dust storage bin 20. During the dust discharge process, the air inlet baffle 26 opens towards the inside of the dust storage bin 20, and the air outlet baffle 27 opens towards the outside of the dust storage bin 20. During the dust suction process, both the air inlet baffle 26 and the air outlet baffle 27 are closed.

[0060] In the above embodiment, the main unit dust collection device 2 further includes an air inlet baffle 26 and an air outlet baffle 27. The air inlet baffle 26 is rotatably connected to the inner side of the dust bin air inlet 22 via a connecting rod 28, so that the air inlet baffle 26 is used to control whether the main unit air inlet channel 31 and the dust storage bin 20 are connected. By opening or closing the dust bin air inlet 22 via the air inlet baffle 26, the timing of external airflow entering the dust storage bin 20 is precisely controlled. The connecting rod 28 is preferably U-shaped, with one end of the connecting rod 28 rotatably connected to the outer wall of the dust storage bin 20 via a spring, and the other end of the connecting rod 28 integrally connected to the air inlet baffle 26. The air outlet baffle 27 is rotatably connected to the outer side of the dust outlet 24, and the air outlet baffle 27 is used to control whether the main unit dust outlet channel 4 and the dust storage bin 20 are connected. The air inlet baffle 26 is inside the dust bin air inlet 22, facing the inside of the dust storage bin 20. The dust outlet baffle 27 is located outside the dust outlet 24, facing the outside of the dust storage bin 20. Both baffles change the airflow and dust transmission path of the dust storage bin 20 at different working stages. During dust removal, the inlet baffle 26 opens inward towards the dust storage bin 20, allowing external airflow to enter the dust storage bin 20 and form a circulating turbulent flow with the internal dust. The dust outlet baffle 27 opens outward towards the dust storage bin 20, allowing the raised dust to be smoothly discharged from the dust storage bin 20 and enter the dust outlet channel 4 of the main unit. During dust collection, both the inlet baffle 26 and the dust outlet baffle 27 close on the dust storage bin inlet 22 and the dust outlet 24, respectively, to prevent dust leakage and ensure that the dust storage bin 20 is in a closed state, so that the dust collection work can proceed normally. The reasonable use of the inlet baffle 26 and the dust outlet baffle 27 effectively controls the airflow and dust entry and exit of the dust storage bin 20, ensuring the cleaning effect of the floor scrubber and the dust collection efficiency of the base station.

[0061] Reference Figures 1-4 In one embodiment, the filter assembly 21 includes a filter support frame 210, a filter body 211, and a cover plate 212. The filter support frame 210 is disposed on the top of the dust storage bin 20.

[0062] In the above embodiment, the filter assembly 21 includes a filter support frame 210, a filter body 211, and a cover plate 212. The filter support frame 210 serves as the basic frame of the entire filter assembly 21 and is installed on top of the dust storage bin 20, providing a stable support structure for the filter body 211 and the cover plate 212. The filter body 211 is placed inside the filter support frame 210 and is the core part for dust filtration. The filter body 211 is preferably a filter screen or filter cotton, connecting the dust storage bin 20 with the filter outlet 23 on the filter support frame 210. This ensures that the air in the dust storage bin 20 must pass through the filter body 211 during the exhaust process, thereby intercepting dust particles. The cover plate 212 is located on the side of the filter body 211 away from the dust storage bin 20, that is, the cover plate 212 is set on the filter body. The top of the support frame 210 has a cover plate 212 on one side connected to the filter support frame 210 via a rotating rod. The other side of the cover plate 212, which is rotatably connected to the filter support frame 210, is snap-fitted to the filter support frame 210, forming an openable and closable structure. The filter body 211, surrounded by the filter support frame 210, forms a complete airflow channel with the internal space of the dust storage bin 20 and the filter outlet 23. The cover plate 212 covers the filter body 211. When snap-fitted, it can effectively prevent dust from leaking from above. At the same time, when it is necessary to maintain or clean the filter body 211, the cover plate 212 can be opened by rotating it, which is convenient for users to clean and replace the filter body 211 regularly, ensuring the long-term stable filtration performance of the filtration system.

The main unit connecting plate 12 is provided with a connecting plate air inlet 13 communicating with the dust bin air inlet 22, and an air inlet buffer space 14 is formed between the main unit connecting plate 12 and the dust storage bin 20. The main unit connecting plate 12 is also provided with a connecting plate air outlet 15 communicating with the filter air outlet 23, and an air outlet buffer space 16 is formed between the main unit connecting plate 12 and the main unit support frame 11.

[0064] In the above embodiments, the main dust collection device 1 includes a main body 10, a main support frame 11, and a main connection plate 12. The main body 10 is the core structure for generating suction in the entire device, including but not limited to a centrifugal fan, an axial fan, and a brushless fan. The main connection plate 12 is connected to the dust collection bin 20 and the filter support frame 210, respectively, and is located on the side of the main dust collection device 2 where the dust bin air inlet 22 and the filter air outlet 23 are provided. The main support frame 11 is connected between the main body 10 and the main connection plate 12, that is, the main body 10 is located on the side of the main support frame 11 away from the main connection plate 12, and the main support frame 11, the main body 10, and the main connection plate 12 are interconnected. The main support frame 11 supports and fixes the main body 10 to ensure its stability during operation. The plate 12 is provided with a connecting plate air inlet 13 that communicates with the dust bin air inlet 22, and an air inlet buffer space 14 is formed between the main unit connecting plate 12 and the dust bin 20, so that the dust bin air inlet 22 and the connecting plate air inlet 13 are located on both sides of the air inlet buffer space 14. After the airflow enters the dust bin air inlet 22, it enters the connecting plate air inlet 13 through the air inlet buffer space 14. The main unit connecting plate 12 is also provided with a connecting plate air outlet 15 that communicates with the filter air outlet 23, and an air outlet buffer space 16 is formed between the main unit connecting plate 12 and the main unit support frame 11, so that the airflow output from the connecting plate air outlet 15 flows out to other positions after passing through the air outlet buffer space 16. The setting of the air inlet buffer space 14 and the air outlet buffer space 16 can make the airflow more stable, avoid the impact of abrupt changes in airflow on the entire dust box structure 100, and improve the stability of dust collection and discharge.

[0065] Reference Figures 1-6 In one embodiment, the main unit air inlet channel 31 includes a first air inlet channel 310 and a second air inlet channel 311 connected to the first air inlet channel 310. The first air inlet channel 310 is isolated from the main unit air outlet channel 30 by a partition plate 315. The second air inlet channel 311 includes a first bend 312, a second bend 313 and a third bend 314. The first bend 312 is connected to the end of the first air inlet channel 310 near the main unit dust collection device 2. The second bend 313 is obliquely connected to the end of the first bend 312 away from the first air inlet channel 310. The third bend 314 is connected to the end of the second bend 313 away from the first bend 312. The third bend 314 is in contact with the main unit support frame 11 and the main unit connecting plate 12 respectively.

[0066] In the above embodiment, the main unit air intake channel 31 includes a first air intake channel 310 and a second air intake channel 311. The first air intake channel 310 and the second air intake channel 311 are connected and are separate components. The first air intake channel 310 is isolated from the main unit air outlet channel 30 by a partition plate 315 to ensure that the airflow of the intake and exhaust does not interfere with each other and to maintain the orderliness of the airflow. The first air intake channel 310 and the main unit air outlet channel 30 are formed by two U-shaped cover plates 212 that are interlocked. The partition plate 315 consists of two parts that are integrally connected to the upper and lower cover plates 212 respectively. The channel formed by fastening the upper and lower cover plates 212 is divided into a first air inlet channel 310 and a main unit air outlet channel 30. The first air inlet channel 310 and the main unit air outlet channel 30 are respectively bent in the direction away from the main unit dust collection device 2, and the width of the first air inlet channel 310 and the main unit air outlet channel 30 gradually increases from the main unit dust collection device 2 towards the free end. At the same time, the space of the first air inlet channel 310 is smaller than the space of the main unit air outlet channel 30. The second air inlet channel 311 includes a first bend 312, a second bend 313 and a third bend 314. Channel 311 is also formed by two upper and lower cover plates 212 fastened together. The lower cover plate 212 of the second air inlet channel 311 can be directly set on the bottom shell of the floor scrubber. The first bend 312 is connected to the end of the first air inlet channel 310 near the dust collection device 2 of the main unit. The first bend 312 is perpendicular to the first air inlet channel 310, thus changing the airflow direction. The second bend 313 is inclined to connect to the first bend 312, that is, the second bend 313 is the end of the first bend 312 away from the first air inlet channel 310 along the direction of the inclined first bend 312. The downward extension further adjusts the airflow direction; the third bend 314 connects to the second bend 313, that is, the third bend 314 is the end of the second bend 313 away from the first bend 312 that extends in a direction parallel to the first bend 312, and the third bend 314 contacts the main support frame 11 and the main connection plate 12 respectively. The third bend 314 connects to the air inlet 13 of the connection plate to ensure that the airflow smoothly enters the main dust collection device 2, which can more effectively agitate the dust in the dust storage bin 20, avoid garbage accumulation in corners, and improve the overall cleaning performance.

[0067] Reference Figure 1 , Figure 7 This invention also proposes a sweeping machine 200, including the aforementioned dust box structure 100 and a sweeping machine body 400. The dust box structure 100 is disposed inside the sweeping machine body 400, wherein the roller is a part of the sweeping machine body 400, ensuring that the sweeping machine 200 can agitate and transfer the dust in the dust box to the integrated base station when collecting dust, thus avoiding the problem of dust residue caused by airflow obstruction in the sweeping machine 200.

[0068] Reference Figures 1-10The third aspect of the present invention also proposes a cleaning system, including the sweeper 200 described in the above embodiments, and also includes a dust collection base station 300. The dust collection base station 300 includes a base station body 301, and a base station fan 302, a base station dust box 303, a base station dust collection channel 304 and a base station blowing channel 305 disposed in the base station body 301.

[0069] The base station fan 302 is mounted on the base station dust box 303, the base station dust collection channel 304 is connected to the base station dust box 303, and the base station dust collection channel 304 corresponds to the host dust outlet channel 4.

[0070] The base station air blowing channel 305 is connected to the base station fan 302, and the base station air blowing channel 305 corresponds to the host air duct module 3. A reflective wall 306 is provided at the end of the base station air blowing channel 305 away from the base station fan 302. The reflective wall 306 is used to control the connection state between the base station air blowing channel 305 and the host air duct module 3.

[0071] In the above embodiment, the cleaning system includes the sweeper 200, and also includes a base station body 301, a base station fan 302, a base station dust box 303, a base station dust collection channel 304, and a base station air blowing channel 305. The base station fan 302, base station dust box 303, base station dust collection channel 304, and base station air blowing channel 305 are respectively disposed within the base station body 301. The base station body 301 provides protection and support for the internal components. The base station fan 302, mounted on the base station dust box 303, generates airflow (including but not limited to centrifugal fans, axial fans, and brushless fans). The negative pressure generated during its operation is used to draw dust from the sweeper 200's dust box into the base station dust box 303. The base station dust box 303 stores dust and debris collected from the sweeper 200 and is connected to the base station dust collection channel 304, forming a dust transmission path. The base station air blowing channel 305 is connected to the base station fan 302, and the base station air blowing channel 305... Channel 305 is used to transport the airflow generated by the base station fan 302. At the same time, the base station blowing channel 305 corresponds to the main air duct module 3 of the sweeper 200, and provides airflow to it through the base station fan 302. The reflector wall 306 is movably connected to the end of the base station blowing channel 305 away from the base station fan 302. Its movable connection method is preferably a sliding connection, that is, an opening is opened in the base station blowing channel 305, and the reflector wall 306 is slidably connected in the opening. It is used to control the communication state between the base station blowing channel 305 and the main air duct module 3. The reflector wall 306 can be controlled by the system to open or close its state automatically, or it can be controlled manually to open or close its state, thereby affecting the airflow circulation and dust collection method. Through the cooperation of the base station fan 302 and related channels, efficient dust collection between the sweeper 200 and the dust collection base station 300 is achieved, reducing the tediousness of manually cleaning the dust box.

[0072] Reference Figures 1-10 , Figure 11 The fourth aspect of the present invention also provides a dust collection method for a cleaning system, comprising the cleaning system described in the above embodiments, and further comprising:

[0073] S1: Move the sweeper 200 to the interface 307 of the dust collection base station 300, so that the dust collection channel 304 of the base station is connected to the dust outlet channel 4 of the host, and the air blowing channel 305 of the base station is connected to the air duct module 3 of the host.

[0074] S2: Determine whether the reflective wall 306 connects the base station air blowing channel 305 to the host air duct module 3;

[0075] S3: If so, the host dust collection device 1 stops operating, the base station fan 302 starts operating, and the base station external airflow generated by the base station fan 302 flows into the host dust collection device 2 through the base station blowing channel 305, the host air outlet channel 30 and the host air inlet channel 31 respectively to form a circulating turbulent flow, and the dust collection airflow of the base station draws the material to be collected in the host dust collection device 2 into the base station dust box 303 through the host dust outlet channel 4 and the base station dust collection channel 304;

[0076] S4: If not, the host dust collection device 1 starts operating first. The host dust collection airflow generated by the host dust collection device 1 is reflected by the reflector wall 306 and flows into the host dust collection device 2 through the host air inlet channel 31 to form a circulating turbulent flow. Then the base station fan 302 starts operating and sucks the object to be collected in the host dust collection device 2 into the base station dust box 303 through the base station dust outlet channel 4 and the base station dust collection channel 304.

[0077] In the above embodiments, the dust collection method of the cleaning system includes the cleaning system described in the above embodiments, and further includes that after the sweeper 200 completes the floor cleaning operation, it automatically or under user instruction goes to the docking interface 307 of the dust collection base station 300. At this time, the sweeper 200 and the dust collection base station 300, through precise mechanical structure and positioning device, make the base station dust collection channel 304 and the host dust outlet channel 4 tightly connected, and at the same time, the base station blowing channel 305 and the host air duct module 3 are also accurately connected. After the docking is completed, the base station system immediately starts the detection program of the reflector wall 306 status. If the reflector wall 306 is detected to be in the state of connecting the base station blowing channel 305 and the host air duct module 3, the host dust collection device 1 immediately stops running, because at this time the external airflow generated by the base station fan 302 is sufficient to form a circulating turbulence in the host dust collection device 2 through a specific path. The base station fan 302 starts to run, and the powerful external airflow generated by it passes through the base station blowing channel 305. The air flows into the main unit's exhaust duct 30 and intake duct 31 respectively, forming a circulating turbulent flow within the main unit's dust collection device 2. Simultaneously, the base station fan 302 generates negative pressure within the base station dust box 303, creating a base station suction airflow. This airflow draws the dust and other items awaiting collection from the main unit's dust collection device 2 into the base station dust box 303 via the main unit's exhaust duct 4 and base station dust collection duct 304. If the reflector wall 306 is not connected to the two, the main unit's suction device 1 starts first, and the suction airflow it generates enters the main unit's intake duct 31 after being reflected by the reflector wall 306, thus forming a circulating turbulent flow within the main unit's dust collection device 2. Subsequently, the base station fan 302 starts again, using the base station suction airflow to draw the items to be collected from the main unit's dust collection device 2 into the base station dust box 303, completing the dust collection process. Therefore, this cleaning system can automatically select the optimal dust collection method according to the actual situation of the equipment, improving dust collection efficiency and reliability, effectively solving the problem of dust residue, improving cleaning quality, and reducing manual operation, bringing a convenient experience to users.

Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
