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

[0042] The technical solution provided by this utility model has the following beneficial effects:

[0043] The vacuuming system provided by this utility model includes a vacuum cleaner, a base station, and a guide air duct. The vacuum cleaner includes a vacuum body, a dust cup assembly, and a floor brush assembly. The floor brush assembly contacts the surface to be cleaned (such as a floor or wall), allowing the suction port to be closer to the surface. The floor brush assembly effectively picks up dirt from the surface and sucks it in, guiding it towards the dust cup assembly. After entering the dust cup assembly, the dirt is filtered through its internal filter structure and stored in the dust cup. Clean airflow is then discharged into the user's environment or outside the user's environment by the vacuum cleaner's motor, creating an airflow circulation for the vacuum cleaner's operation. The base station includes a base station body, and the vacuum body and / or the base station body are equipped with a suction device. After the vacuum cleaner finishes vacuuming... Afterwards, the vacuum cleaner can be placed on the base station, allowing the dust cup assembly to connect with the first storage chamber on the base station. The floor brush assembly is then placed on the placement area. When the suction device is activated, airflow is generated, and the dirt in the dust cup assembly enters the first storage chamber under the action of the airflow, achieving self-cleaning of the dust cup assembly. Simultaneously, the clean airflow discharged from the first storage chamber flows outward under the guidance of the guide air duct. Since the guide air duct is connected to the second storage chamber through the first pair of interfaces, and the second storage chamber is connected to the placement area, when the airflow passes through the first pair of interfaces, a negative pressure is created at least at the first pair of interfaces. This creates airflow from the second storage chamber towards the first pair of interfaces and into the guide air duct. Under the action of this airflow, dirt on the floor brush assembly is carried into the second storage chamber by the airflow, achieving self-cleaning of the floor brush assembly. The self-cleaning of the floor brush assembly does not require a separate drive device to provide suction power, making the structure of the entire vacuum system simpler and the cost lower. This vacuuming system not only enables self-cleaning of the dust cup assembly but also the floor brush assembly, resulting in better cleaning performance. Furthermore, a single suction device provides the power for both the dust cup and floor brush self-cleaning, simplifying the structure and reducing costs. The entire cleaning process requires no manual intervention from the user, effectively reducing their workload and enhancing their user experience. Attached Figure Description

[0057] This utility model provides a dust collection system; for details, please refer to [link / reference]. Figures 1 to 3 In this embodiment, the vacuuming system includes: a vacuum cleaner 100, including a vacuum cleaner body 1, and a dust cup assembly 2 and a floor brush assembly 3 disposed on the vacuum cleaner body 1; a base station 200, including a base station body 4, on which a first storage cavity 41 for collecting dust from the dust cup assembly 2 and a second storage cavity 42 for collecting dust from the floor brush assembly 3 are formed, and a placement area for placing the floor brush assembly 3 is provided, the second storage cavity 42 being connected to the placement area; a suction device 8 is provided on the vacuum cleaner body 1 and / or the base station body 4; a guide air duct 7, adapted to allow the suction device 8 to be fluidly connected to the outside, and a first pair of interfaces 721 connected to the second storage cavity 42 is provided on one side of the guide air duct 7; wherein, the suction device 8 generates airflow from the dust cup assembly to the first storage cavity 41, and the airflow is discharged to the outside through the guide air duct 7 after passing through the first storage cavity 41, at least creating a negative pressure at the first pair of interfaces 721, so as to form airflow from the second storage cavity 42 into the guide air duct 7 through the first pair of interfaces 721. In this invention, the airflow can be generated by the suction device 8 installed on the base station body, or by the vacuum cleaner motor. In this case, the vacuum cleaner motor is the suction device, which blows air onto the dust cup assembly through a reverse rotation or air duct switching structure; or the airflow can be generated by both.

[0058] In this embodiment, the floor brush assembly 3 contacts the surface to be cleaned (such as the floor, wall, etc.), allowing the suction port 511 to be closer to the surface. The floor brush assembly 3 can better pick up and suck up dirt from the surface and guide it towards the dust cup assembly 2. After entering the dust cup assembly 2, the dirt can be filtered through the filter structure inside the dust cup assembly 2. The filtered dirt will be stored in the dust cup of the dust cup assembly 2. The clean airflow will be discharged into the user's environment or outside the user environment by the vacuum cleaner 100's suction motor, forming an airflow circulation for the vacuum cleaner 100's vacuuming operation. Moreover, the base station 200 includes a base station body 4, a vacuum body 1, and / or a suction device 8 on the base station body 4. After the vacuum cleaner 100 finishes vacuuming, it can be placed on the base station 200, allowing the dust cup assembly 2 to be placed on the base station 200. The first storage chamber 41 of the dust cup assembly 2 is connected to the floor brush assembly 3, which is placed on the placement area. When the suction device 8 is turned on, an airflow is generated, and the dirt in the dust cup assembly 2 is sucked into the first storage chamber 41 under the action of the airflow, realizing the self-cleaning of the dust cup assembly 2. At the same time, the clean airflow discharged through the first storage chamber 41 can flow to the outside under the guidance of the guide air duct 7. Since the guide air duct 7 is connected to the second storage chamber 42 through the first pair of interfaces 721, and the second storage chamber 42 is connected to the placement area, when the airflow flows through the first pair of interfaces 721, at least a negative pressure is formed at the first pair of interfaces 721, so as to form an airflow from the second storage chamber 42 toward the first pair of interfaces 721 and into the guide air duct 7. Under the action of this airflow, the dirt on the floor brush assembly 3 can enter the second storage chamber 42 with the airflow, realizing the self-cleaning of the floor brush assembly 3. The self-cleaning of the floor brush assembly 3 does not require a separate drive device to provide suction power, and the structure of the entire vacuum system 1000 can be simpler and the cost is lower. The vacuum system 1000 can not only self-clean the dust cup assembly 2 of the vacuum cleaner 100, but also self-clean the floor brush assembly 3, resulting in a better cleaning effect for the vacuum cleaner 100. Moreover, a single suction device 8 can provide the self-cleaning power for both the dust cup assembly 2 and the floor brush assembly 3, making the structure simpler and the cost lower. Furthermore, the entire cleaning process does not require manual intervention from the user, effectively reducing the user's labor intensity and improving the user experience.

[0059] In one embodiment, the suction device 8 is disposed on the base station body 4, and the air inlet of the suction device 8 is connected to the first storage cavity 41; the air guide duct 7 connects the air outlet of the suction device 8 to the outside, and the airflow discharged from the air outlet of the suction device 8 is discharged to the outside through the air guide duct 7.

[0060] The guide air duct 7 serves two purposes: firstly, it guides the clean airflow discharged from the suction device 8 to the user's living space or outside the living space; secondly, it reduces the air pressure at the first pair of interfaces 721, or in the lateral air duct 72 connecting the first pair of interfaces 721 and the second storage cavity 42, creating a pressure difference between the second storage cavity 42 and the lateral air duct 72. Preferably, it combines... Figure 3 and Figure 4 As shown, the cross-sectional area of ​​the guide duct 7 at the first pair of interfaces 721 is smaller than that at other locations. When the airflow flows from the area with a larger cross-sectional area to the area with a relatively smaller cross-sectional area, the corresponding flow velocity will increase, and its static pressure will decrease, thus forming a pressure difference with the surrounding airflow. Figure 3 The dashed arrows indicate the airflow direction, allowing airflow to flow from the placement area toward the second storage cavity 42 and toward the first pair of interfaces 721, thereby drawing dirt from the floor brush assembly 3 into the second storage cavity 42. By utilizing the airflow discharged by the suction device 8, the floor brush assembly 3 achieves self-cleaning power, making the cleaning method simpler and the cleaning cost lower.

[0061] Understandably, there are several ways to configure the air duct 7. The air duct 7 can be integrated with the base station 200, or it can be configured independently and detachably installed on the base station 200. Alternatively, the air duct 7 can be enclosed by the internal structure of the base station body 4, or it can be a detachable external pipe, or it can be located on the outside of the base station body 4 and enclosed by an external enclosure structure, etc. The specific configuration of the air duct 7 can be determined according to the actual structure of the base station 200, and will not be listed here.

[0062] Preferably, combined with Figure 2 and Figure 3As shown, the guiding air duct 7 is configured as a Venturi tube 71, and preferably, the cross-section of the Venturi tube 71 is approximately circular. One end of the Venturi tube 71 is connected to the air outlet of the suction device 8, and the other end of the Venturi tube 71 faces outward from the base station body 4. After the airflow discharged from the air outlet of the suction device 8 enters the Venturi tube 71, it is guided by the Venturi tube 71 and discharged from one side of the base station body 4. Specifically, the Venturi tube 71 has an inlet section 711, a constriction section 712, a throat 713, and a diffuser section 714 arranged in sequence. The inlet section 711 is connected to the air outlet of the suction device 8, the first pair of interfaces 721 is provided on the throat 713, and the end of the diffuser section 714 faces outward from the base station body 4. Therefore, according to the Venturi effect, in a high-speed flowing gas, when the gas passes through the narrow part (throat) in the pipe, the flow velocity increases and the pressure decreases, thus causing the air pressure in the throat 713 to decrease, thereby creating a pressure difference with the surrounding area. This causes the airflow in the second storage cavity 42 to flow towards the first pair of interfaces 721 and towards the Venturi tube 71 under the action of the pressure difference, thereby carrying the dirt on the floor brush assembly 3 into the second storage cavity 42, achieving the cleaning of the floor brush assembly 3.

[0063] In addition, a filter or isolation structure can be installed at the end of the venturi tube 71 facing the outside of the base station body 4 to prevent external debris from entering the venturi tube 71 and causing blockage.

[0064] A lateral air duct 72 is provided on one side of the second storage cavity 42. The lateral air duct 72 is connected to the first pair of interfaces 721, and the guide channel 7 and the second storage cavity 72 are connected through the lateral air duct 72. Preferably, the lateral air duct 72 is perpendicular to the guide air duct 7, and the lateral air duct 72 is shorter, resulting in less air resistance to the airflow, thus improving the efficiency of cleaning dirt from the floor brush assembly 3.

[0065] For vacuum cleaner 100, combined Figure 1 and Figure 2 As shown, the vacuum cleaner 100 also includes a handle. The handle of the vacuum cleaner 100 is positioned near the dust cup assembly 2 of the vacuum cleaner 100. A dust guide tube is connected between the dust cup assembly 2 and the floor brush assembly 3, extending vertically and parallel to the central axis of the dust cup assembly 2. The handle is connected to the upper end of the dust cup assembly 2, and the floor brush assembly 3 is located at the lower end of the dust cup assembly 2. By connecting the dust cup assembly 2 and the floor brush assembly 3 through the dust guide tube, the floor brush assembly 3 can protrude downwards from the dust cup assembly 2, allowing it to better reach low-lying areas. Furthermore, the user has a longer cleaning arm and finds operation easier.

[0066] It should be noted that, as Figure 1As shown, with the direction of the vacuum cleaner 100 placed on the base station 200 as a reference, the dust cup assembly 2 is located above the floor brush assembly 3, and the dust cup assembly 2 and the floor brush assembly 3 are staggered in the vertical direction, so that the floor brush assembly 3 is located on one side of the dust cup assembly 2. All descriptions of orientation in this utility model can be referred to accordingly.

[0067] When the vacuum cleaner 100 is placed on the base station 200, the suction device 8 and the dust cup assembly 2 are arranged coaxially, and at least a portion of the venturi tube 71 is arranged coaxially with the suction device 8. The venturi tube 71 can be better arranged in the direction of airflow, resulting in less wind resistance. When flowing towards the first pair of interfaces 721, the wind speed is greater, resulting in higher efficiency of the suction airflow.

[0068] Furthermore, in order to better connect the Venturi tube 71 to the second storage cavity 42, preferably, at least a portion of the Venturi tube 71 can be arranged around the outer periphery of the second storage cavity 42, so that the Venturi tube 71 is closer to the second storage cavity 42 and the resulting airflow pressure difference is greater.

[0069] It is understandable that the second storage cavity 42 can be formed on any path connecting the air outlet of the self-suction device 8 to the outside world. At the same time, the second storage cavity 42 is connected to the placement area, so that the space between the placement area and the dust cup assembly 2 can accommodate the floor brush assembly 3.

[0070] Preferably, the placement area is located near the bottom of the base station body 4, so that after the vacuum cleaner 100 is placed on the base station 200, the floor brush component 3 is also closer to the ground, the overall center of gravity is lower, and the stability is better.

[0071] The placement area is used to house the ground brush assembly 3, thereby restricting the movement of the ground brush assembly 3 relative to the base station body 4.

[0072] Preferably, such as Figure 2 As shown, the base station body 4 is provided with a mounting groove 512 for at least a portion of the ground brush assembly 3 to be accommodated therein. The second storage cavity 42 is connected to the mounting groove 512, which forms a placement area for the ground brush assembly 3. The mounting groove 512 can restrict the periphery of the ground brush assembly 3, ensuring the stability of the placement of the ground brush assembly 3. On the other hand, the mounting groove 512 can cover the ground brush assembly 3, preventing dirt on the ground brush assembly 3 from splashing during the self-cleaning process and causing secondary pollution.

[0073] Among them, combined Figure 4 and Figure 5As shown, the second storage cavity 42 has a dust suction port 511 connected to the mounting groove 512 and a second pair of interfaces 521 connected to the side air duct 42. The dust suction port 511 and the second pair of interfaces 521 are located on opposite sides of the second storage cavity 42. Preferably, the dust suction port 511 and the second pair of interfaces 521 are arranged opposite each other in the vertical direction. Dirt on the floor brush assembly 3 can enter the second storage cavity 42 from the dust suction port 511 under the action of air pressure difference and driven by airflow, thereby cleaning the dirt on the floor brush assembly 3.

[0074] Furthermore, the second pair of interfaces 521 is located at the bottom of the second storage cavity 42, and at least a portion of the guide channel passes through the bottom of the second storage cavity 42. This allows the generated suction airflow to flow better in a downward direction, and also allows dirt on the floor brush assembly 3 to enter the second storage cavity 42 under its own gravity, resulting in higher dirt collection efficiency.

[0075] In one embodiment, the second storage cavity 42 and the mounting slot 512 are detachably connected, which facilitates separate maintenance of the second storage cavity 42 and the mounting slot 512.

[0076] Preferably, the second storage cavity 42 and the mounting slot 512 can be integrally formed. Specifically, as shown in the example... Figure 5 As shown, the base station 200 also includes a dust box 5, which comprises a first housing 51 and a second housing 52 connected to each other. The first housing 51 and the second housing 52 enclose a second storage cavity 42. The first housing 51 has a mounting groove 512 formed on its side facing away from the second housing 52. Specifically, the second housing 52 is recessed and has an upward-facing opening. The first housing 51 covers the opening of the second housing 52 and has the mounting groove 512 on its side facing away from the first housing 51, allowing the floor brush assembly 3 to be placed on the first housing 51. This makes the second storage cavity 42 and the mounting groove 512 closer together, facilitating communication and reducing wind resistance when sucking up dirt from the floor brush assembly 3, thus effectively improving the dirt suction efficiency.

[0077] Furthermore, the first housing 51 is movably disposed on the second housing 52, having an open state for opening the second storage cavity 42 and a closed state for closing the second storage cavity 42. By movably disposing the first housing 51, the second storage cavity 42 can be exposed when the first housing 51 is in the open state, thereby facilitating the cleaning and maintenance of the interior of the second housing 52.

[0078] In one embodiment, the first housing 51 and the second housing 52 are rotatably connected. Specifically, both the first housing 51 and the second housing 52 are generally square in shape to form a cuboid dust box 5. Both the first housing 51 and the second housing 52 have two long sides and two short sides arranged opposite each other. One side of the first housing 51 is rotatably connected to the second housing 52, and the other side of the first housing 51 is engaged with the second housing 52. Preferably, one long side of the first housing 51 is rotatably connected to one long side of the second housing 52, and the other long side of the first housing 51 is engaged with the other long side of the second housing 52, ensuring the reliability of the connection between the first housing 51 and the second housing 52.

[0079] A hook may be provided on one of the first housing 51 and the second housing 52, and a buckle may be provided on the other housing to engage with the hook. The engagement of the hook and the buckle allows the first housing 51 to be in a closed state, ensuring that dirt in the second storage cavity 42 will not leak out.

[0080] In another embodiment, the first housing 51 is slidably disposed on the second housing 52 to switch between an open state and a closed state. Specifically, a slide rail may be provided on the second housing 52, and a slider may be provided on the first housing 51. The slider is slidably disposed on the slide rail, so that a drawer-type structure is formed between the first housing 51 and the second housing 52, making it more convenient to switch the state of the first housing 51.

[0081] Furthermore, a dust bag 6 can be installed inside the second storage cavity 42. Dirt entering the second storage cavity 42 can enter the dust bag 6 for filtration, while clean airflow can flow from the second pair of ports 521 into the first pair of ports 721 and then exit through the venturi tube 71. When in the open state, at least a portion of the dust bag 6 is exposed, facilitating its replacement without requiring cleaning of the second storage cavity 42, thus simplifying operation.

[0082] Furthermore, the first housing 51 is generally recessed, and includes a bottom housing wall and a plurality of side housing walls protruding from the bottom housing wall on the side facing away from the second housing 52. Preferably, four side housing walls are provided to surround the four sides of the square bottom housing wall. The bottom housing and the plurality of side housing walls together form the aforementioned mounting groove 512, and each side housing wall has a guide surface at the end facing away from the bottom housing wall to guide the floor brush assembly 3 toward the mounting groove 512, so that when the vacuum cleaner 100 is placed on the base station 200, the floor brush assembly 3 can fall more smoothly into the mounting groove 512.

[0083] The suction port 511 is located on the bottom shell wall, and preferably in the middle of the bottom shell wall. The second pair of interfaces 521 are located on the second shell 52 and are opposite to the suction port 511, so that the airflow is smoother.

[0084] For the floor brush assembly 3, it is used to contact the surface to be cleaned during normal vacuuming operations of the vacuum cleaner 100 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 in the mounting groove 512. Specifically, the floor brush assembly 3 includes a floor brush housing 31 and a roller brush 32 rotatably mounted on the floor brush housing 31. Through the rotation of the roller brush 32, it contacts and rubs against the surface to be cleaned, rolling up the dirt on the surface and sucking it into the dust guide tube from the suction port at the bottom of the floor brush housing 31, so that it enters the dust cup assembly 2. The floor brush assembly 3 can rotate relative to the dust guide tube. 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, 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 mounting groove 512 and be closer to the suction port 511. 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.

[0085] When the vacuum cleaner 100 is placed on the base station 200 for self-cleaning, the roller brush 32 is rotatably mounted in the mounting groove 512. Specifically, the floor brush assembly 3 also includes a scraping component located on one side of the roller brush 32. When the roller brush 32 is self-cleaning, as the roller brush 32 rotates, the scraping component can scrape away dirt from various parts of the roller brush 32, resulting in a better cleaning effect.

[0086] In one embodiment, when the roller brush 32 is disposed in the mounting slot 512, 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.

[0087] In another embodiment, when the roller brush 32 is disposed in the mounting slot 512, the base station 200 further includes a first driving structure. The first driving structure is disposed on the dust box 5. When the roller brush 32 is disposed in the mounting slot 512, the first driving structure is driven to connect with the roller brush 32 and 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 mounting slot 512. At this time, the first driving structure is in contact 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 5 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.

[0088] In another embodiment, the roller brush 32 can be driven to rotate by the airflow formed within the mounting groove 512. For example, the roller brush 32 can rotate on its own under the suction airflow formed by the venturi tube 71; or, an auxiliary air duct is also provided within the mounting groove 512, which generates airflow that blows toward the roller brush 32, driving the roller brush 32 to rotate. Moreover, the airflow in the auxiliary air duct can originate from the airflow blown from the exhaust end of the suction device 8 on the base station 200, guiding a portion of the airflow from the exhaust end of the suction device 8 into the mounting groove 512, causing the roller brush 32 to rotate, and blowing away dirt from the sidewalls of the roller brush 32, resulting in a wider cleaning range and better cleaning effect for the floor brush assembly 3.

[0089] During normal cleaning operation of the vacuum cleaner 100, the roller brush 32 rotates in a first direction. When the roller brush 32 is self-cleaning within the mounting groove 512, it rotates in a second direction, with the first and second directions being opposite. For example, when the first direction is clockwise, the second direction is counterclockwise. When the roller brush 32 is self-cleaned via the base station 200, the reverse rotation of the roller brush 32 makes it easier for dirt adhering to it to fall off, effectively improving the cleaning efficiency of the roller brush 32.

[0090] Furthermore, during the self-cleaning process of the roller brush 32 within the mounting slot 512, the roller brush 32 rotates alternately along the first and second directions. Compared to rotating only along the second direction, the alternating rotation results in a better self-cleaning effect, and the hair wrapped around the roller brush 32 is more easily loosened and carried away by the airflow.

[0091] Because the vacuum cleaner 100 is elongated and narrow, its length is relatively long. Correspondingly, the height of the base station 200 should be adapted to the vacuum cleaner 100. This ensures that when the vacuum cleaner 100 is placed on the base station 200, after the dust cup assembly 2 is aligned with the base station 200, there is sufficient space for the floor brush assembly 3 to be placed. Specifically, in conjunction with... Figure 5 and Figure 6 As shown, the base station body 4 also includes a base 43 and a support 44 protruding from the base 43. The base 43 is generally disc-shaped to form a bottom support with sufficient area. One end of the support 44 is connected to the base 43, and the other end of the support 44 extends upward to support the suction device 8 at a certain height. The first storage cavity 41 is located above the suction device 8, 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 first storage cavity 41 and communicate with the first storage cavity 41. A gap is formed between the top of the support 44 and the base 43; the dust box 5 is located on the base 43 to better connect with the floor brush assembly 3 located at the bottom of the vacuum cleaner 100. The air guide duct 7 can pass through the bottom of the support 44 and extend towards the base 43. The airflow at the suction device 8 is guided towards the base 43 by the guide air duct 7. When the airflow flows through the dust box 5, the change in the cross section of the venturi tube 71 reduces the air pressure in the side air duct 72. As a result, the airflow in the mounting groove 512 and the second storage cavity 42 can flow better into the side air duct. Under the action of the airflow, the dirt on the roller brush 32 in the mounting groove 512 is carried out.

[0092] This utility model also provides a vacuuming system 1000, which includes a vacuum cleaner 100 and a base station 200. The vacuum cleaner 100 and the base station 200 can be the vacuum cleaner 100 and base station 200 described in the above embodiments, or they can be different from the vacuum cleaner 100 and base station 200 described in the above embodiments. Specifically, in conjunction with... Figure 3 , Figure 4 and Figure 6 As 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 and a suction device 8 disposed on the base station body 4. The base station body 4 has a first storage cavity 41 and a second storage cavity 42, and a placement area for placing the floor brush assembly 3. The air inlet of the suction device 8 is connected to the first storage cavity 41, and the second storage cavity 42 is connected to the placement area; the guide air duct 7 is adapted to connect the air outlet of the suction device 8 to the outside; the lateral air duct 72 connects the guide air duct 7 and the second storage cavity 42; wherein, the guide air duct 7 and the lateral air duct 72 are perpendicular to each other, and when the airflow flows through the guide air duct 7, the air pressure in the lateral air duct 72 is less than the air pressure in the second storage cavity 42.

[0093] In this embodiment, by setting the guide air duct 7 perpendicular to the side air duct 72, the airflow in the second storage cavity 42 can enter the guide air duct 7 with a shorter distance, resulting in less wind resistance and higher airflow efficiency in the second storage cavity 42, thus improving the cleaning efficiency of the floor brush assembly 3.

[0094] The side air duct 72 has a first pair of interfaces 721, and the second storage cavity 42 has a second pair of interfaces 521. The first pair of interfaces 721 and the second pair of interfaces 521 are connected to each other. The first pair of interfaces 721 and the second pair of interfaces 521 are connected to each other to connect the guide air duct 7 and the second storage cavity 42, making assembly and disassembly more convenient.

[0095] Preferably, such as Figure 3 As shown, when the guide air duct 7 is configured as a venturi tube 71, at least a portion of the inlet section 711 is coaxially arranged with the suction device 8, so that the airflow is smoother and more efficient when it is discharged from the outlet end of the suction device 8.

[0096] More preferably, such as Figure 6 As shown, the lateral air duct 72 and the guide air duct 7 are integrally formed. The lateral air duct 72 is a side tube protruding from one side of the venturi tube 71. It is connected to the second pair of interfaces 521 through the side tube, making the connection between the venturi tube 71 and the second storage cavity 42 simpler and more convenient.

[0097] The first pair of interfaces 721 is located at the middle of the throat 713 of the venturi tube 71. Along the airflow direction, and along the direction close to the first pair of interfaces 721, the cross-section of the constriction section 712 of the venturi tube 71 gradually decreases, and along the direction away from the first pair of interfaces 721, the cross-section of the diffuser section 714 of the venturi tube 71 gradually increases, so that the cross-sectional area of ​​the venturi tube 71 is minimized at the position corresponding to the first pair of interfaces 721. Therefore, when the airflow passes through the first pair of interfaces 721, the air pressure in the throat 713 decreases, causing the airflow in the second storage cavity 42 to flow into the lateral air duct 72.

[0098] The inlet section 711 of the venturi tube 71 extends along the axial direction of the suction device 8 and is arranged in the direction of the air outlet of the suction device 8, so that the airflow can enter the venturi tube 71 more smoothly and the power of the airflow can be better preserved. The inlet section 711 also has a horizontal part connected to the converging section 712 to guide towards the bottom of the dust box 5, so as to better fix the relative position of the venturi tube 71 and the dust box 5.

[0099] In another embodiment of the vacuuming system 1000, when the airflow is discharged to the outside through the guide air duct 7, the airflow velocity at the first pair of interfaces 721 is greater than that at other locations. At least a portion of the guide air duct 7 is parallel to the axis of the suction device 8, making the structure of the entire base station 200 more compact. Moreover, the guide air duct 7 does not protrude from the base station body 4, and the guide air duct 7 does not occupy additional space outside the base station 200, making the overall volume of the base station 200 smaller, and effectively achieving the cleaning of the dust cup assembly 2 and the floor brush assembly 3.

[0100] 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.
