Description

Technical Field

[0001] This utility model relates to the technical field of cleaning tools, specifically to a vacuuming system. Background Technology

[0002] The vacuuming system consists of a vacuum cleaner and a base station. The vacuum cleaner can operate independently of the base station for cleaning. After cleaning, the vacuum cleaner can be placed on the base station, which charges it, allowing for continuous use. The vacuum cleaner includes a dust cup assembly and a floor brush assembly. The floor brush assembly contacts the surface to be cleaned (such as the floor). The floor brush assembly and the dust cup assembly are connected. The floor brush assembly picks up and sucks up dirt (such as dust, debris, and hair) from the floor, guiding it into the dust cup assembly. After multiple filtrations, the dirt is collected in the dust cup. In traditional vacuuming systems, after the vacuum cleaner is placed on the base station, the suction device on the base station can suck the dirt from the dust cup into the base station, achieving self-cleaning of the dust cup. However, the floor brush assembly is the part that has the most contact with the floor, and its roller brush easily accumulates dirt. Traditional base stations cannot clean the floor brush assembly, requiring manual cleaning by the user, increasing the user's workload and resulting in a poor user experience. Utility Model Content

[0034] The technical solution provided by this utility model has the following beneficial effects:

[0035] The vacuuming system provided by this utility model includes a vacuum cleaner, a base station, and a dirt collection structure. The vacuum cleaner includes a dust cup assembly and a floor brush assembly. The dust cup assembly is used to store dirt sucked up by the vacuum cleaner when cleaning surfaces (such as floors, walls, etc.). The floor brush assembly is connected to the dust cup assembly and is used to directly contact the surface to be cleaned. The floor brush assembly picks up dirt from the surface and sucks it into the dust cup assembly, achieving effective cleaning of the surface. The base station is used to place the vacuum cleaner and is provided with a placement part for the floor brush assembly. Furthermore, the dirt collection structure is connected to the air inlet of the suction device through a dirt storage component, which allows negative pressure to be formed inside the dirt storage component when the suction device is working. This creates a negative pressure in the first and second dirt-guiding channels connected to the dirt storage unit. The dirt drawn from the floor brush assembly is guided through the first dirt-guiding channel into the dirt storage unit, while the dirt in the dust cup assembly is drawn out through the second dirt-guiding channel and guided into the dirt storage unit. Therefore, a single suction device can clean both the dust cup assembly and the floor brush assembly, resulting in a simple structure, low cost, and higher cleaning efficiency. Furthermore, a single dirt storage unit can simultaneously store dirt from both the dust cup assembly and the floor brush assembly, reducing the number of storage cavities and saving space. This allows for a smaller overall vacuuming system with a simpler structure. Attached Figure Description

[0047] This utility model provides a vacuuming system 1000. For details, please refer to [link / reference needed]. Figures 1 to 2In this embodiment, the vacuuming system 1000 includes a vacuum cleaner 100, a base station 200, and a dirt collection structure 6. The vacuum cleaner 100 includes a vacuuming body 1, a dust cup assembly 2 and a floor brush assembly 3 disposed on the vacuuming body 1. The base station 200 includes a base station body 4, a suction device 5 disposed on the base station body 4, and a placement part for placing the floor brush assembly 3. The dirt collection structure 6 includes a dirt storage component 61, a first dirt guiding channel 62 and a second dirt guiding channel 63 connected to the dirt storage component 61. The dirt storage component 61 is connected to the air inlet end of the suction device 5, the first dirt guiding channel 62 is connected to the placement part, and the second dirt guiding channel 63 is used to connect and communicate with the dust cup assembly 2.

[0048] In this embodiment, the dust cup assembly 2 can be used to store the dirt sucked up by the vacuum cleaner 100 when cleaning a surface to be cleaned (such as a floor, wall, etc.). The floor brush assembly 3 is connected to the dust cup assembly 2 and is used to directly contact the surface to be cleaned. The floor brush assembly 3 picks up the dirt on the surface to be cleaned and sucks it into the dust cup assembly 2, thereby achieving effective cleaning of the surface to be cleaned. The base station 200 is used to place the vacuum cleaner 100 and is provided with a placement part for placing the floor brush assembly 3. Moreover, the dirt storage component 61 of the dirt collection structure 6 is connected to the air inlet of the suction device 5. When the suction device 5 is working, a negative pressure can be formed in the dirt storage component 61, thereby allowing the first dirt guiding channel 62 connected to the dirt storage component 61 to be connected. A negative pressure is formed in the second dirt-guiding channel 63, so that dirt in the placement part, that is, dirt sucked from the floor brush assembly 3, can be guided through the first dirt-guiding channel 62 into the dirt storage component 61. Moreover, dirt in the dust cup assembly 2 can be sucked out through the second dirt-guiding channel 63 and guided into the dirt storage component 61. Therefore, the dust cup assembly 2 and the floor brush assembly 3 can be cleaned by a single suction device 5. The structure is simple, the cost is low, and the cleaning efficiency is higher. In addition, dirt in the dust cup assembly 2 and the floor brush assembly 3 can be stored in a single dirt storage component 61, which reduces the number of dirt storage cavities and saves more space. Therefore, the entire vacuum system 1000 can be smaller and the structure is simpler.

[0049] Among them, combined Figure 2 and Figure 3As shown, the vacuum cleaner 100 also includes a dust guide tube 33 connecting the floor brush assembly 3 and the dust cup assembly 2. The dust guide tube 33 is used to guide the dirt sucked in by the floor brush assembly 3 into the dust cup assembly 2. The dust guide tube 33 is located on one side of the dust cup assembly 2, and preferably, both the dust cup assembly 2 and the dust guide tube 33 are generally cylindrical, with the axis of the dust guide tube 33 parallel to the axis of the dust cup assembly 2. The dust guide tube 33 is connected to one side of the dust cup assembly 2, with the dust cup assembly 2 near one end of the dust guide tube 33, and the floor brush assembly 3 located at the other end of the dust guide tube 33. When the vacuum cleaner 100 is in normal use and in cleaning mode, the floor brush assembly 3 contacts the surface to be cleaned. The floor brush assembly 3 includes a roller brush 32, a roller brush driver connected to the roller brush 32, and a suction port located on one side of the roller brush 32. The roller brush driver drives the roller brush 32 to rotate, so that the roller brush 32 contacts and rubs against the surface to be cleaned, so as to roll up the dust, impurities and other dirt on the surface to be cleaned, and then suck the dirt into the dust guide tube 33 through the suction port, so as to guide the dirt into the dust cup assembly 2 through the dust guide tube 33, and store the dirt through the dust cup of the dust cup assembly 2.

[0050] After the vacuum cleaner 100 has finished cleaning, it can be placed on the base station 200. The base station 200 can then charge the vacuum cleaner 100 and perform self-cleaning. Specifically, when the vacuum cleaner 100 is placed on the base station 200, the dust guide tube 33 extends vertically, the dust cup assembly 2 is located at the upper end of the dust guide tube 33, and the floor brush assembly 3 is located at the lower end of the dust guide tube 33. The dust cup assembly 2 and the floor brush assembly 3 are staggered vertically. In the following description, in conjunction with… Figure 1 Unless otherwise specified, the directions shown are based on the orientation of the vacuum cleaner 100 placed on the base station 200.

[0051] It is understandable that the pollution collection structure 6 can be integrated into the base station 200, making the base station 200 more powerful; or, the pollution collection structure 6 can be an independent entity, existing separately, easy to move, and making the structure of the base station 200 simpler.

[0052] Preferably, the dirt collection structure 6 is located on the base station 200, which reduces the number of parts in the entire vacuum system 1000 and makes it more convenient to use.

[0053] In order to collect the dirt in the dust cup assembly 2 and the dirt on the floor brush assembly 3 into the dirt storage component 61, the first dirt guiding channel 62 can directly or indirectly connect the placement part and the dirt storage component 61, and the second dirt guiding channel 63 can directly or indirectly connect the dust cup assembly 2 and the dirt storage component 61.

[0054] The arrangement of the second dirt-guiding channel 63 will also differ depending on the different first dirt-guiding channels 62. Specifically, the first dirt-guiding channel 62 may be connected to the dirt-storage component 61; or, the first dirt-guiding channel 62 may be connected to the second dirt-guiding channel 63; or, the second dirt-guiding channel 63 may be connected to the first dirt-guiding channel 62.

[0055] In one embodiment, one or more first connecting members may be provided between the dirt storage member 61 and the first dirt guiding channel 62, and the first dirt guiding channel 62 and the dirt storage member 61 may be connected through one or more first connecting parts, so that the first dirt guiding channel 62 can be connected to the dirt storage member 61.

[0056] In another embodiment, the first dirt-guiding channel 62 can be directly connected to the dirt-storing component 61, avoiding the need for too many intermediate components, which would result in high wind resistance and affect dust collection efficiency.

[0057] Similarly, in one embodiment, one or more second connecting components may be provided between the dirt storage component 61 and the second dirt guiding channel 63 to connect the second dirt guiding channel 63 and the dirt storage component 61, so that the second dirt guiding channel 63 can be connected to the dirt storage component 61.

[0058] In another embodiment, the second contaminant channel 63 can be directly connected to the contaminant storage component 61, making the structure of the base station 200 simpler.

[0059] Furthermore, since the second dirt-guiding channel 63 is used to connect with the dust cup assembly 2 to guide dirt into the dirt storage component 61, in one embodiment, the second dirt-guiding channel 63 can also be configured as a dirt inlet of the dirt storage component 61. When the vacuum cleaner 100 is placed on the base station 200, it connects with the dirt outlet of the dust cup assembly 2 through the dirt inlet, so that when the suction device 5 is working, the dirt in the dust cup assembly 2 can be directly discharged from the dirt outlet into the dirt inlet and enter the dirt storage component 61, resulting in higher dirt suction efficiency.

[0060] The dust cup assembly 2 includes a dust cup and a dust cup cover. The bottom of the dust cup is a drain outlet, and the dust cup cover can open and close the drain outlet. When the vacuum cleaner 100 is placed on the base station 200 for self-cleaning, the dust cup cover is opened to allow the dirt inside the dust cup to be discharged and enter the dirt storage component 61 of the base station 200. Preferably, combined with Figure 3 and Figure 4As shown, the second dirt-guiding channel 63 includes a docking cavity 631 located at one end of the dirt-storing component 61 and connected to it. When the vacuum cleaner 100 is placed on the base station 200, at least a portion of the dust cup assembly 2 is housed in the docking cavity 631. That is, when the dust cup cover is open, the dust cup cover can rotate toward the docking cavity 631 to open the dust cup. After the dust cup cover is opened, the dirt in the dust cup falls into the docking cavity 631 under its own gravity and the suction force of the suction device 5. Then, the dirt is guided into the dirt-storing component 61 by the docking cavity 631. At this time, the first dirt-guiding channel 62 can directly connect the docking cavity 631 and the placement part, so that the dirt at the floor brush assembly 3 can be guided into the docking cavity 631 through the first dirt-guiding channel 62 and then into the dirt-storing component 61. Under the guidance of the docking cavity 631, the dirt can enter the dirt-storing component 61 more effectively.

[0061] Furthermore, such as Figure 4 As shown, the docking cavity 631 is generally funnel-shaped and has a first pair of interfaces 6311 and a second pair of interfaces 6312. The first pair of interfaces 6311 is arranged upwards and formed at the flared end of the docking cavity 631, while the second pair of interfaces 6312 is arranged downwards to communicate with the dirt storage component 61. The second pair of interfaces 6312 is formed at the constricted end of the docking cavity 631. Dirt can enter the docking cavity 631 through the first pair of interfaces 6311 and enter the dirt storage component 61 through the second pair of interfaces 6312. Specifically, after the vacuum cleaner 100 is placed on the base station 200, dirt in the dust cup assembly 2 can fall into the docking cavity 631, and dirt conducted to the floor brush assembly 3 through the first dirt guiding channel 62 can also fall into the docking cavity 631. Through the guiding effect of the docking cavity 631, dirt can flow better toward the second pair of interfaces 6312 and enter the dirt storage component 61 under the action of the suction device 5.

[0062] More preferably, the docking cavity 631, the dirt storage component 61, and the suction device 5 are arranged sequentially from top to bottom along the base station body 4. When the dust cup assembly 2 is docked with the docking cavity 631, it is placed at the first pair of interfaces 6311 of the docking cavity 631. Therefore, after the dust cup cover of the dust cup assembly 2 is opened, the dirt can fall into the docking cavity 631 under its own gravity, and further enter the dirt storage component 61 better under the suction action of the suction device 5, making the recycling of dirt smoother.

[0063] Moreover, preferably, such as Figure 4As shown, the docking cavity 631, the dirt storage component 61, and the suction device 5 are coaxially arranged, ensuring that the dust cup assembly 2, docking cavity 631, and dirt storage component 61 are all centered. Therefore, after dirt falls into the dirt storage component 61, it will not accumulate on one side of the component, resulting in more even dispersion of dirt within the component 61 and a larger amount of dirt collected. Furthermore, the suction device 5 is also coaxially arranged with the dirt storage component 61. When the airflow flows from the dust cup assembly 2 towards the docking cavity 631 and into the dirt storage component 61, the wind resistance formed in the flow channel is smaller, and the airflow efficiency is higher, thus resulting in higher dirt removal efficiency.

[0064] Of course, the configuration of the second contaminant channel 63 is not limited to the above-described forms. In other embodiments, the second contaminant channel 63 may also be configured as a contaminant pipe 621 or a channel enclosed by the rib structure inside the base station body 4. Since there are many configuration forms for the second contaminant channel 63, any configuration that allows the dust cup assembly 2 and the contaminant storage component 61 to pass through should fall within the protection scope of this application.

[0065] The first dirt-guiding channel 62 is used to draw dirt from the placement area of ​​the floor brush assembly 3 into the dirt storage container 61. It can be understood that the specific form of the first dirt-guiding channel 62 can be configured according to the form of the placement portion of the floor brush assembly 3. Specifically, a recessed placement groove can be formed on the base station body 4. When the vacuum cleaner 100 is placed on the base station 200, at least a portion of the floor brush assembly 3 is accommodated within the placement groove. The first dirt-guiding channel 62 can be connected to one side of the placement groove, thereby drawing out dirt from the floor brush assembly 3 that has fallen into the placement groove.

[0066] Preferably, combined with Figure 3 and Figure 4 As shown, the placement part includes a receiving cavity 43 disposed on the base station body 4. The relative positions of the receiving cavity 43 and the docking cavity 631 match the relative positions of the dust cup assembly 2 and the floor brush assembly 3, so that when the vacuum cleaner 100 is placed on the base station 200, the dust cup assembly 2 is precisely housed in the docking cavity 631, and the floor brush assembly 3 is precisely housed in the receiving cavity 43, making the alignment of the dust cup assembly 2 and the floor brush assembly 3 more convenient, and making it more convenient for the user to place.

[0067] Furthermore, the docking direction of the dust cup assembly 2 and the docking cavity 631 is consistent with the docking direction of the floor brush assembly 3 and the receiving cavity 43. When placing the vacuum cleaner 100 on the base station 200 in one direction, the user can achieve the alignment of the dust cup assembly 2 and the docking cavity 631, as well as the alignment of the floor brush assembly 3 and the receiving cavity 43. The user does not need to repeatedly adjust the placement direction and position of the dust cup assembly 2 or the floor brush assembly 3. The user-friendly operation method makes the user experience better.

[0068] Preferably, such as Figure 2 As shown, both the receiving cavity 43 and the docking cavity 631 have upward-facing openings. When placing the vacuum cleaner 100, it can be placed on the base station 200 from top to bottom. At this time, the dust cup assembly 2 can be placed from top to bottom at the first interface 6311 of the docking cavity 631, and the floor brush assembly 3 can enter the receiving cavity 43 from top to bottom through the opening of the receiving cavity 43. When the user releases their grip, both the dust cup assembly 2 and the floor brush assembly 3 are in place, and the self-cleaning state can begin. Preferably, the first dirt-guiding channel 62 is connected to the bottom of the receiving cavity 43. After the dirt on the floor brush assembly 3 falls into the receiving cavity 43, it can better enter the first dirt-guiding channel 62 from the bottom of the receiving cavity 43, thereby guiding it into the dirt storage component 61.

[0069] Of course, in other embodiments, the openings of the accommodating cavity 43 and the docking cavity 631 can also be oriented in other directions. For example, the openings of the accommodating cavity 43 and the docking cavity 631 can both face one side in the horizontal direction, such as facing the left side of the base station body 4. Then, when placing the vacuum cleaner 100, the vacuum cleaner 100 can be placed on the base station 200 from left to right in the horizontal direction, so that the floor brush assembly 3 and the dust cup assembly 2 can be placed in place at the same time.

[0070] Specifically, the first contamination channel 62 may be formed inside the base station 200, enclosed by the ribs inside the base station 200, or enclosed by multiple components inside the base station 200. Alternatively, the first contamination channel 62 may be at least partially formed on the outside of the base station body 4, enclosed by external components of the base station body 4.

[0071] Preferably, the first wastewater guiding channel 62 is configured as a wastewater guiding pipe 621, with one end of the wastewater guiding pipe 621 communicating with the receiving cavity 43 and the other end communicating with the docking cavity 631. Waste from the floor brush assembly 3 is guided into the wastewater storage component 61 through the wastewater guiding pipe 621. This design facilitates easier disassembly and assembly of the wastewater guiding pipe 621 with the docking cavity 631 and the receiving cavity 43, and makes it easier to replace and maintain the wastewater guiding pipe 621.

[0072] Further relating to the floor brush assembly 3, the floor brush assembly 3 is used to contact the surface to be cleaned during normal vacuuming operations of the vacuum cleaner 100, in order to suck up dirt from the surface. When the vacuum cleaner 100 is placed on the base station 200, the floor brush assembly 3 is housed within the receiving cavity 43. Specifically, as... Figure 4As shown, the floor brush assembly 3 includes a floor brush housing 31 and a roller brush 32 rotatably mounted on the floor brush housing 31. By rotating the roller brush 32 and contacting and rubbing against the surface to be cleaned, dirt on the surface to be cleaned is rolled up and sucked into the dust guide tube 33 from the suction port at the bottom of the floor brush housing 31, so as to enter the dust cup assembly 2. The floor brush assembly 3 can rotate relative to the dust guide tube 33. When the vacuum cleaner 100 is in the cleaning state, the suction port on the floor brush assembly 3 faces the surface to be cleaned. When the vacuum cleaner 100 is placed on the base station 200, the floor brush assembly 3 can rotate 90° relative to the dust guide tube 33, so that the suction port of the floor brush assembly 3 faces one side and the roller brush 32 is located at the bottom of the vacuum cleaner 100. Thus, the roller brush 32 can better extend into the receiving cavity 43 and be more closely positioned at the bottom of the receiving cavity 43. Moreover, after the floor brush assembly 3 is flipped over, the area occupied by the floor brush assembly 3 in the horizontal direction is smaller, so the area occupied by the base station body 4 in the horizontal direction is smaller, and the volume of the base station 200 can also be smaller.

[0073] Preferably, when the vacuum cleaner 100 is placed on the base station 200 for self-cleaning, the roller brush 32 is rotatably disposed within the receiving cavity 43. Specifically, the floor brush assembly 3 also includes a scraping member disposed on one side of the roller brush 32. During the self-cleaning of the roller brush 32, when the roller brush 32 rotates, the scraping member can scrape away dirt from various parts of the roller brush 32, resulting in a better cleaning effect of the roller brush 32.

[0074] In one embodiment, when the roller brush 32 is disposed in the receiving cavity 43, the roller brush 32 can rotate under the drive of the roller brush driver on the vacuum cleaner 100 to perform self-cleaning of the roller brush 32.

[0075] In another embodiment, when the roller brush 32 is disposed within the receiving cavity 43, the base station 200 further includes a first driving structure. The first driving structure is disposed on the base station body 4. When the roller brush 32 is disposed within the receiving cavity 43, the first driving structure is driven to connect with the roller brush 32, and the first driving structure is used to drive the roller brush 32 to rotate. When the vacuum cleaner 100 is placed on the base station 200, the roller brush 32 is positioned in the receiving cavity 43. At this time, the first driving structure is engaged with the roller brush 32, thereby driving the roller brush 32 to rotate and achieving self-cleaning of the roller brush 32. The first driving structure can be movably disposed on the dust box and can move automatically or manually to connect with the roller brush 32 when it is positioned, so that the roller brush 32 can be driven to rotate.

[0076] In another embodiment, the roller brush 32 can be driven to rotate by the airflow formed within the accommodating cavity 43. For example, the roller brush 32 can rotate on its own under the action of the suction airflow formed by the dirt guide pipe 621; or, an auxiliary air duct is also provided within the accommodating cavity 43, which generates airflow within the auxiliary air duct and blows the airflow toward the roller brush 32, thereby driving the roller brush 32 to rotate. Moreover, the airflow in the auxiliary air duct can originate from the airflow blown from the air outlet of the suction device 5 on the base station 200. Specifically, the base station 200 also includes an exhaust channel that connects the air outlet of the suction device 5 and the placement part, guiding a portion of the airflow from the air outlet of the suction device 5 into the accommodating cavity 43, causing the roller brush 32 to rotate, and blowing away dirt on the roller brush 32 and / or the sidewalls of the roller brush 32, resulting in a wider cleaning range and better cleaning effect for the floor brush assembly 3.

[0077] During normal cleaning operation of the vacuum cleaner 100, the roller brush 32 rotates in a first direction. When the roller brush 32 is within the receiving cavity 43, it rotates in at least a second direction, wherein the first and second directions are opposite. For example, when the first direction is clockwise, the second direction is counterclockwise. When the roller brush 32 is self-cleaned by the base station 200, the reverse rotation of the roller brush 32 makes it easier for dirt adhering to the roller brush 32 to fall off, effectively improving the cleaning efficiency of the roller brush 32.

[0078] Furthermore, during the self-cleaning process of the roller brush 32 within the receiving cavity 43, the roller brush 32 rotates alternately along the first direction and the second direction. Compared to rotating only along the second direction, the self-cleaning effect brought about by the alternating rotation is better, and the hair wrapped on the roller brush 32 is easier to loosen and be carried away from the roller brush 32 by the airflow.

[0079] In one embodiment, combined with Figure 1 and Figure 2 As shown, the base station body 4 also includes a base 41 and a support 42 protruding from the base 41. The base 41 is generally disc-shaped to form a bottom support with sufficient area. One end of the support 42 is connected to the base 41, and the other end of the support 42 extends upward to support the suction device 5 at a certain height. The dirt storage component 61 is disposed above the suction device 5, so that when the vacuum cleaner 100 is placed on the base station 200, the dust cup assembly 2 can be better placed above the dirt storage component 61 and communicate with the dirt storage component 61. A gap is formed between the top of the support 42 and the base 41; a receiving cavity 43 is disposed on the base 41 to better align with the floor brush assembly 3 located at the bottom of the vacuum cleaner 100.

[0080] In one embodiment, a valve structure may be provided on the first and / or second dirt guide channels. The valve structure can control the opening and closing of the first and / or second dirt guide channels, thereby controlling whether the dust cup assembly 2 and the floor brush assembly 3 are self-cleaning components, making the cleaning methods more flexible and diverse.

[0081] Specifically, a first valve can be installed on the first dirt-guiding channel, and a second valve can be installed on the second dirt-guiding channel. When only the dust cup assembly 2 needs to be cleaned, the second valve can be opened and the first valve can be closed simultaneously, allowing dirt in the dust cup assembly 2 to enter the dirt storage container 61 through the second dirt-guiding channel. When only the floor brush assembly 3 needs to be cleaned, the first valve can be opened and the second valve can be closed simultaneously, allowing dirt at the floor brush assembly 3 to enter the dirt storage container 61 under the guidance of the first dirt-guiding channel 62. When both the floor brush assembly 3 and the dust cup assembly 2 are self-cleaning simultaneously, the first and second valves are opened simultaneously, allowing dirt at the floor brush assembly 3 to be guided into the dirt storage container 61 through the first dirt-guiding channel 62, while dirt in the dust cup assembly 2 can be guided into the dirt storage container 61 through the second dirt-guiding channel 63, achieving simultaneous removal of dirt from both locations and improving cleaning efficiency.

[0082] Furthermore, by controlling the opening and closing of the first and second valves, the time required for cleaning dirt from the dust cup assembly 2 and the floor brush assembly 3 can be better controlled. For example, if there is a lot of dirt in the dust cup assembly 2 and the cleaning time is relatively longer, the first valve can be closed after simultaneously opening the first and second valves for a certain period of time. This results in a stronger suction airflow within the dust cup assembly 2, thereby improving cleaning efficiency and saving energy. This allows the base station 200 to offer more diverse self-cleaning modes for the vacuum cleaner 100, resulting in higher cleaning efficiency and better cleaning effects.

[0083] This utility model also provides a vacuuming system 1000, which includes a vacuum cleaner 100, a base station 200, and a dirt collection structure 6. The vacuum cleaner 100, base station 200, and dirt collection structure 6 can be the same as those described in the above embodiments, or they can be novel vacuum cleaners 100, base stations 200, and dirt collection structures 6, different from those described in the above embodiments. In this embodiment, combined with... Figure 4As shown, the vacuum cleaner 100 includes a vacuum body 1, a dust cup assembly 2 and a floor brush assembly 3 disposed on the vacuum body 1; the base station 200 includes a base station body 4, a suction device 5 disposed on the base station body 4, and a placement part for placing the floor brush assembly 3 therein; the dirt collection structure 6 includes a dirt storage component 61, and a first dirt guiding channel 62 and a second dirt guiding channel 63 connected to the dirt storage component 61. The dirt storage component 61 is connected to the air inlet end of the suction device 5. The first dirt guiding channel 62 is connected to the placement part. The second dirt guiding channel 63 is used to connect and communicate with the dust cup assembly 2. At least a portion of the first dirt guiding channel 62 and at least a portion of the second dirt guiding channel 63 are arranged in parallel, and the airflow directions within the two parallel channel segments are opposite.

[0084] In this embodiment, the first dirt-guiding channel 62 removes dirt from the floor brush assembly 3, and the second dirt-guiding channel 63 simultaneously removes dirt from the dust cup assembly 2, enabling both the dust cup assembly 2 and the floor brush assembly 3 to achieve self-cleaning. Furthermore, dirt on the floor brush assembly 3 and in the dust cup assembly 2 can be stored in the dirt storage component 61, reducing the space occupied by the dirt storage cavity and the overall size of the vacuuming system 1000. The use of a single suction device 5 also simplifies the structure and lowers costs. Moreover, when the dust cup assembly 2 and the floor brush assembly 3 are simultaneously self-cleaning, the airflow directions in the two dirt-guiding channels are opposite, allowing the vibrations generated by the suction airflow to be better canceled out. Therefore, the base station 200 operates more stably and generates less noise.

[0085] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
