[0002] This application claims priority to Chinese Patent Application No. 202510363243.X, filed on March 25, 2025, entitled "Cleaning Equipment, Base Station and Cleaning System", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This utility model relates to the field of cleaning tool technology, and in particular to a vacuum cleaner and cleaning system. Background Technology

[0004] Cleaning equipment typically includes filters, vacuum heads, suction devices, and dust cups. External dirt is sucked in through the vacuum head and guided into the dust cup, where it is filtered. The dirt is then retained in the dust cup, while the filtered clean airflow flows out of the filter, enters the suction device, and is discharged from the cleaning equipment, forming an airflow cycle for cleaning.

[0005] When cleaning, dirty air drawn in by the vacuum head enters the dust cup through the air inlet and rotates around the cylindrical filter. When the cleaning equipment sucks in some longer hair, due to the principle of the cyclone separator, the airflow drives the hair to rotate around the filter. After long-term use, the longer hair will wrap around the filter surface, causing the filter to become clogged and affecting the efficiency of dust collection and filtration. Utility Model Content

Detailed Implementation

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] In cleaning equipment such as vacuum cleaners, mite removers, and robot vacuums, dirty air drawn in by the suction head enters the dust cup through the air inlet and rotates around the filter. When the cleaning equipment sucks in longer hairs, based on the principle of a cyclone separator, the airflow carries the hair around the filter. After prolonged use, longer hairs become entangled on the filter surface, clogging it and affecting the dust filtration efficiency. To remove the hair entangled on the cyclone separator surface, an additional cleaning mechanism is required, resulting in a complex overall structure, increased weight, and a negative impact on the user experience. Furthermore, the cleaning mechanism needs to extend from the main unit into the dust cup, which may cause sealing problems, and the complex structure is prone to malfunction, also increasing costs. Therefore, this invention proposes a cleaning device that, by optimizing its structure, improves the efficiency of cleaning dirt entangled on the filter surface.

[0036] Combination Figures 1 to 3 According to the first aspect of the present invention, a vacuum cleaner 100 includes a main unit 10, which includes a suction device 11. The suction device 11 can be used to provide negative pressure, and under the action of negative pressure, the vacuum cleaner 100 can easily clean dust, hair and other dirt from the working surface.

[0037] The vacuum cleaner 100 also includes a dust cup 21 and a lid 22. The dust cup 21 has an air inlet 211, an air outlet 212, and a dust discharge port 213. The lid 22 is closable at the dust discharge port 213. Exemplarily, the vacuum cleaner 100 may have a working mode and a self-cleaning mode. In the working mode, the lid 22 can close the dust discharge port 213 to facilitate the collection of dust, hair, and other contaminants sucked in by the vacuum cleaner 100 through the dust cup 21. Figure 10 In self-cleaning mode, the cup lid 22 can open the dust outlet 213 to facilitate cleaning of dirt inside the dust cup 21.

[0038] Combination Figure 3 The vacuum cleaner 100 also includes a filter device 30, at least a portion of which extends into the dust cup 21. Specifically, during operation, the cup lid 22 closes the dust outlet 213, and the suction device 11 provides negative pressure. Under this negative pressure, the vacuum cleaner 100 draws dust, hair, and other contaminants from the work surface into the dust cup 21 through the air inlet 211. The clean airflow filtered by the filter device 30 is then discharged from the air outlet 212 through the suction device 11 to the outside of the vacuum cleaner 100. When it is necessary to clean the contaminants in the dust cup 21, the cup lid 22 opens the dust outlet 213.

[0039] Combination Figure 3The filter device 30 includes a rotating part 31 and a fixed part 32. The vacuum cleaner 100 has a working mode and a self-cleaning mode. In the self-cleaning mode, the rotating part 31 rotates, and in the working mode, it stops rotating. Specifically, the fixed part 32 is relatively fixed, while the rotating part 31 can rotate. Understandably, when the vacuum cleaner 100 is working, the dust-laden airflow enters the dust cup 21 from the air inlet 211, forming a high-speed rotating airflow within the dust cup 21. Hair and other filamentous materials easily become entangled on the outside of the filter device 30, potentially causing blockage after prolonged use. By providing the rotating part 31, the hair and other filamentous materials entangled on the surface of the filter device 30 can be loosened by rotating the rotating part 31, facilitating separation of the hair and other filamentous materials from the filter device 30. This eliminates the need for an additional cleaning mechanism for the filter device 30 and prevents blockage, allowing the vacuum cleaner 100 to maintain a good cleaning effect even after prolonged use.

[0040] For example, in the working mode of the vacuum cleaner 100, the rotating part 31 can be in a stopped state. In this state, the rotating part 31 cannot rotate, and the filter device 30 can filter the dust-laden air entering the dust cup 21, preventing the rotation of the rotating part 31 from affecting the filtration effect of the filter device 30, thereby ensuring the working efficiency of the vacuum cleaner 100. In the self-cleaning mode of the vacuum cleaner 100, the rotating part 31 can be in a rotating state. The rotation of the rotating part 31 can loosen hair and other filaments entangled in the filter device 30, facilitating the separation of hair and other filaments from the filter device 30, eliminating the need for an additional cleaning mechanism for cleaning the filter device 30. Of course, in the self-cleaning mode, the rotating part 31 can rotate and stop as needed. For example, the rotating part 31 can have a stopped state depending on the driving method and control method, so that the state of the rotating part 31 can be adjusted according to actual usage requirements.

[0041] Combination Figure 2 and Figure 3 The vacuum cleaner 100 also includes a flow guiding structure 12, wherein, combined with Figure 3 In operating mode, the airflow inside the dust cup 21 enters from the outside of the rotating part 31 and flows to the suction device 11 from the air outlet 212. Specifically, under the action of the suction device 11, the vacuum cleaner 100 can draw dust, hair, and other dirt from the working surface into the dust cup 21 through the air inlet 211. The clean airflow filtered by the filter device 30 is discharged from the air outlet 212 through the suction device 11 to the outside of the vacuum cleaner 100. Figure 5In self-cleaning mode, the airflow guide structure 12 restricts at least part of the airflow from the air outlet 212 to the inside of the rotating part 31, and the rotating part 31 rotates under the drive of the airflow entering the dust cup 21. That is to say, in the rotating state, the rotating part 31 is mainly driven to rotate by the airflow on its outside. The airflow guide structure 12 restricts the airflow from the air outlet 212 to the inside of the rotating part 31, which can avoid the airflow turbulence when the rotating part 31 rotates, thereby improving the rotational stability of the rotating part 31.

[0042] Understandably, the dust cup 21 has an air inlet 211 and an air outlet 212. When the cleaning device 100 is in self-cleaning mode, airflow may enter the inner side of the rotating part 31 through the air outlet 212, and airflow may enter the outer side of the rotating part 31 through the air inlet 211. By setting the airflow guide structure 12 to restrict at least part of the airflow from the air outlet 212 to the inner side of the rotating part 31, it is possible to avoid airflow turbulence and affect the rotation efficiency of the rotating part 31.

[0043] According to the vacuum cleaner 100 of this utility model embodiment, the rotating part 31 can rotate in the self-cleaning mode, which can loosen the hair entangled in the filter device 30, making it easier for the hair and the like to be separated from the filter device 30. In this way, by setting the airflow guide structure 12 to restrict at least part of the airflow from the air outlet 212 to the inside of the rotating part 31, and the rotating part 31 is driven by the airflow entering the dust cup 21 to rotate, the airflow turbulence can be reduced, the rotational stability of the rotating part 31 can be improved, and thus it is easier for the hair and the like to be separated from the rotating part 31, thereby improving the cleaning efficiency of the filter device 30.

[0044] It should be noted that in the self-cleaning mode, the flow guiding structure 12 restricts at least part of the airflow from the air outlet 212 to the inside of the rotating part 31. That is, in the rotating state, the flow guiding structure 12 can block at least part of the airflow from entering the inside of the rotating part 31, so as to reduce the impact of the airflow from the air outlet 212 entering the inside of the rotating part 31 on the rotating part 31; or, the flow guiding structure 12 completely restricts the airflow from the air outlet 212 to the inside of the rotating part 31. That is, under the action of the flow guiding structure 12, the airflow from the air outlet 212 can be completely blocked from entering the inside of the rotating part 31, and the rotating part 31 is driven to rotate by the airflow on the outside, avoiding airflow turbulence and improving the rotational stability of the rotating part 31.

[0045] The flow guiding structure 12 may include a switch valve, which separates the suction device 11 and the air outlet 212 in the self-cleaning mode; or, the flow guiding structure 12 may include an air duct switching component 121, which fluidly connects the suction device 11 and the dust cup 21 in the working mode, and separates the suction device 11 and the dust cup 21 in the self-cleaning mode.

[0046] Optionally, the filter device 30 can be connected to the main unit 10 via the fixing part 32. It is understood that the dust cup 21 and the main unit 10 are typically detachably connected. When the dust cup 21 is installed on the main unit 10, at least a portion of the filter device 30 extends into the dust cup 21 to facilitate the filtration of dust and dirt drawn into the dust cup 21. When the dust cup 21 is separated from the main unit 10, the filter device 30 remains connected to the main unit 10. This makes disassembly of the dust cup 21 more convenient when it needs to be replaced or cleaned, improving the efficiency of dust cup assembly and disassembly. Furthermore, the connection of the filter device 30 to the main unit 10 via the fixing part 32 makes the structure of the filter device 30 more stable, improving the operational stability of the filter device 30 and reducing the impact of the dust cup 21 on the filter device 30 during assembly and disassembly. For example, the upper end of the fixing part 32 may be provided with a snap-fit ​​groove, and the main unit 10 may be provided with a buckle. The fixing part 32 and the main unit 10 can be rotated and snapped together through the snap-fit ​​structure, so that the filter device 30 is fixed on the main unit 10 and the filter device 30 is located upstream of the suction fan. The filter device 30 is detachably connected to the main unit 10, which facilitates the maintenance of the filter device 30.

[0047] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the airflow guiding structure 12 includes an air duct switching component 121, combined with... Figure 4 In the working mode air duct switching component 121, fluid communication is established between the suction device 11 and the dust cup 21, combined with Figure 5 In self-cleaning mode, the air duct switching component 121 blocks the airflow from the air outlet 212 to the dust cup 21, and the rotating part 31 rotates under the influence of the airflow entering the dust cup 21 through the air inlet 211. Specifically, when the vacuum cleaner 100 is vacuuming, the rotating part 31 is in a stopped state. The air duct switching component 121 connects the suction device 11 to the dust cup 21. The dust-laden airflow enters the dust cup 21 from the air inlet 211. The airflow enters the inner side of the rotating part 31 from the outside and is filtered by the rotating part 31. The filtered clean airflow flows from the air outlet 212 to the suction device 11. At this time, the rotating part 31 can be in a stopped state and cannot rotate, so that the filter device 30 can maintain a stable filtration effect. When the vacuum cleaner 100 is self-cleaning, the rotating part 31 can be in a rotating state. The air duct switching component 121 separates the dust cup 21 and the suction device 11. The rotating part 31 is driven to rotate by the airflow entering from the air inlet 211. At this time, no airflow enters the inner side of the rotating part 31 from the air outlet 212, so as to avoid airflow turbulence affecting the rotation efficiency of the rotating part 31. The airflow guiding structure 12 includes an air duct switching component 121, which can be used to directly restrict the airflow entering the rotating part 31 in the self-cleaning mode, thus simplifying the structure of the main unit 10.

[0048] Combination Figures 4 to 6Furthermore, the air duct switching component 121 has a suction port 1211, a self-cleaning interface 1212, and a dust cup interface 1213. The suction port 1211 is fluidly connected to the suction device 11, and the dust cup interface 1213 is fluidly connected to the dust cup 21. The main unit 10 is provided with a self-cleaning air duct 13 that is fluidly connected to the self-cleaning interface 1212. In the working mode, the suction port 1211 is fluidly connected to the dust cup interface 1213 and the suction port 1211 is separated from the self-cleaning interface 1212. In the self-cleaning mode, the suction port 1211 is separated from the dust cup interface 1213 and the suction port 1211 is fluidly connected to the self-cleaning interface 1212. The vacuum cleaner 100 can be connected to the base station. By setting a self-cleaning air duct 13 and an air duct switching component 121 on the main body, the vacuum cleaner 100's suction device 11 can generate negative pressure in the base station. The base station does not need to be equipped with a motor, which can realize the self-cleaning of the vacuum cleaner 100. The air duct switching component 121 can realize the switching of the air duct. At the same time, in the self-cleaning mode, when the rotating part 31 is rotating, the air duct switching component 121 can restrict the airflow into the rotating part 31, avoid the airflow entering the rotating part 31 from the air outlet 212 from affecting the rotating part 31, improve the rotational stability of the rotating part 31, and simplify the structure of the main unit 10.

[0049] Specifically, in the working mode, the rotating part 31 of the vacuum cleaner 100 can be in a stopped state, the air duct switching component 121 makes the suction port 1211 fluidly connected to the dust cup interface 1213, and the suction port 1211 is separated from the self-cleaning interface 1212. The suction head sucks dust, hair, debris and other dirt from the working surface into the dust cup 21 through the air inlet 211. The cup cover 22 closes the dust outlet 213. The filter device 30 filters the airflow. The clean airflow filtered by the filter device 30 is discharged to the outside of the vacuum cleaner 100 through the air outlet 212. After the vacuum cleaner 100 completes its cleaning work, it can be connected to the base station. In self-cleaning mode, the rotating part 31 of the vacuum cleaner 100 can rotate. Because the air duct switching component 121 blocks the airflow from the outlet 212 to the dust cup 21, and the suction port 1211 is fluidly connected to the self-cleaning interface 1212, that is, the suction device 11 is fluidly connected to the self-cleaning air duct 13, the dust cup 21 is fluidly connected to the base station, and the base station is fluidly connected to the self-cleaning air duct 13. Under the action of the suction device 11, a cleaning process is generated inside the base station. Negative pressure causes dust, debris, hair, and other contaminants in the dust cup 21 to be collected in the base station. The airflow in the base station flows back to the suction device 11 through the self-cleaning air duct 13 and is discharged outside the vacuum cleaner 100 through the suction device 11. At this time, because the air duct switching component 121 blocks the airflow from the air outlet 212 to the dust cup 21, the airflow will not enter the dust cup 21 interface 1213 from the suction port 1211, thereby ensuring that the airflow from the air outlet 212 will not enter the inside of the rotating part 31, and avoiding airflow turbulence from affecting the rotational stability of the rotating part 31. By setting a self-cleaning air duct 13 and an air duct switching component 121 on the vacuum cleaner 100, the base station does not need to be equipped with a motor. By using the suction device 11 of the vacuum cleaner 100 to generate negative pressure in the base station, the negative pressure inside the base station can clean the dust cup 21 of the vacuum cleaner 100, simplifying the structure of the base station and reducing the noise of the base station during operation. At the same time, when the rotating part 31 rotates, the air duct switching component 121 can be used to block the airflow entering the inside of the rotating part 31, thereby improving the rotational stability of the rotating part 31.

[0050] The air duct switching component 121 is configured to selectively fluidly connect the suction port 1211 to the dust cup interface 1213 and the self-cleaning interface 1212. In other words, the air duct switching component 121 can selectively fluidly connect the suction device 11 to the dust cup 21 and the self-cleaning air duct 13 to achieve air duct switching of the vacuum cleaner 100 in different modes. For example, the air duct switching component 121 can switch the air duct under the operation of the user. For example, the vacuum cleaner 100 may be provided with an operating part, which can be used to switch the air duct of the air duct switching component 121; or, the air duct switching component 121 can achieve air duct switching by cooperating with the structure corresponding to the base station. For example, the base station may be provided with a trigger part. After the vacuum cleaner 100 is connected to the base station, the trigger part triggers the air duct switching component 121 to switch the air duct, without requiring additional operation from the user, thus simplifying the user's operation steps.

[0051] Combination Figure 6 Optionally, the air duct switching assembly 121 includes a switching body 1214 and a sealing switching element 1215. The suction port 1211, the self-cleaning interface 1212 and the dust cup interface 1213 are disposed on the switching body 1214. The sealing switching element 1215 is connected to the switching body 1214 and is used to control the fluid communication and separation between the suction port 1211 and the dust cup interface 1213 and the self-cleaning interface 1212. Specifically, in the working mode, the sealing switch 1215 controls the suction port 1211 to be fluidly connected to the dust cup interface 1213, so that the suction device 11 is fluidly connected to the dust cup 21. In the self-cleaning mode, the sealing switch 1215 controls the suction port 1211 to be fluidly connected to the self-cleaning interface 1212, so that the suction device 11 is fluidly connected to the self-cleaning air duct 13, so that the suction device 11 can generate negative pressure in the base station. At the same time, the sealing switch 1215 blocks the airflow from the air outlet 212 to the dust cup 21, so as to prevent the airflow from entering the inside of the rotating part 31 from the suction port 1211 and affecting the rotating part 31. By setting the switching body 1214 and the sealing switch 1215 to cooperate, the structure of the air duct switching component 121 is simplified, which makes it easier for the vacuum cleaner 100 to switch the air duct in different modes, and can restrict the airflow from entering the inside of the rotating part 31 when rotating.

[0052] Combination Figure 5In some embodiments of this utility model, the air duct switching component 121 is located between the suction device 11 and the filter device 30. In the self-cleaning mode, the air duct switching component 121 restricts the airflow entering the inner side of the rotating part 31 from the air outlet 212, making the structure of the vacuum cleaner 100 more compact. For example, when the cleaning device 100 is in working mode, the airflow filtered by the filter device 30 flows from the inner side of the rotating part 31 through the air outlet 212 to the suction device 11, and then to the outside of the vacuum cleaner 100. In other words, there is a suction air duct between the suction device 11 and the filter device 30. By placing the air duct switching component 121 between the suction device 11 and the filter device 30, it is convenient for the air duct switching component 121 to block the channel between the suction device 11 and the filter device 30 in the self-cleaning mode, so that the suction device 11 is disconnected from the air outlet 212, thereby preventing the airflow from entering the inner side of the rotating part 31 from the air outlet 212.

[0053] In some embodiments of this utility model, the flow guiding structure 12 includes a switching valve that separates the suction device 11 and the air outlet 212 in self-cleaning mode. Exemplarily, in operating mode, the switching valve can be opened to allow fluid communication between the suction device 11 and the air outlet 212, so that the clean airflow filtered by the filter device 30 flows through the air outlet 212 to the suction device 11 and is discharged outside the vacuum cleaner 100. In self-cleaning mode, the switching valve can be closed to separate the suction device 11 from the air outlet 212, preventing the airflow from the air outlet 212 from entering the inner side of the rotating part 31 and avoiding airflow turbulence during rotation of the rotating part 31.

[0054] In some embodiments of this invention, in self-cleaning mode, the airflow guiding structure 12 restricts the airflow from the outlet 212 to the inside of the rotating part 31 along the axial direction of the filter device 30. Combined with Figure 5 As shown, the axis of the filter device 30 is A. The flow guiding structure 12 restricts the airflow to flow along the axis towards the inside of the rotating part 31, which can avoid the airflow turbulence on the inside and outside of the rotating part 31. When the airflow is introduced into the dust cup 21 through the air inlet 211, the airflow on the outside of the rotating part 31 stably drives the rotating part 31 to rotate, thereby improving the rotational stability of the rotating part 31.

[0055] Combination Figure 7 In some embodiments of this invention, blades 311 are provided on the outer side of the rotating part 31. Specifically, the blades 311 are adapted to be driven by the airflow entering the dust cup 21 from the air inlet 211. For example, when the vacuum cleaner 100 is in self-cleaning mode, the base station may have negative pressure, driving the airflow from the air inlet 211 to the dust outlet 213 to collect the dirt in the dust cup 21 into the base station. Providing blades 311 on the rotating part 31 can, on the one hand, push the rotating part 31 to rotate under the action of the airflow, and on the other hand, can also prevent hair and other objects from getting tangled on the outer side of the rotating part 31.

[0056] The blades 311 may include multiple blades arranged in a circumferential direction.

[0057] In some embodiments of this invention, at least a portion of the blade 311 extends along an axial direction. Exemplarily, the entire blade 311 may extend along an axial direction; or, a portion of the blade 311 may extend along an axial direction, while another portion forms an angle with the axis. Extending at least a portion of the blade 311 along an axial direction ensures that the normal of the blade 311 is parallel to the airflow direction, optimizing the airflow's pushing effect on the blade 311 and thereby improving hair removal efficiency.

[0058] In some embodiments of this utility model, at least a portion of the blade 311 has an angle with the axis, and the angle is less than 90°, so that the airflow can act on the blade 311, drive the blade 311 to rotate, and thus stably drive the rotating part 31 to rotate.

[0059] Preferably, the included angle is less than 45° to enhance the propulsive effect of the airflow on the blade 311.

[0060] In some embodiments of this utility model, the blade 311 is arranged opposite to the air inlet 211 so that the airflow through the air inlet 211 drives the blade 311 to rotate, thereby further enhancing the driving effect of the airflow on the blade 311.

[0061] Combination Figure 5 , Figure 7 and Figure 8 In some embodiments of this utility model, the rotating part 31 includes an impeller assembly 312 and a secondary dust chamber 313, and the fixed part 32 includes a secondary filter 321 and a shaft 322. The secondary filter 321 is disposed above the secondary dust chamber 313, and the shaft 322 passes through the impeller assembly 312 along the rotation axis of the rotating part 31. Specifically, the secondary dust chamber 313 can be used to collect the dust filtered by the secondary filter 321. The impeller assembly 312 can be driven to rotate by the airflow entering from the air inlet 211 to drive the rotating part 31 to rotate. The shaft 322 passes through the impeller assembly 312 along the rotation axis, and the shaft 322 can stably support the rotation of the rotating part 31, thereby improving the rotational stability of the rotating part 31.

[0062] The impeller assembly 312 is equipped with a bearing 33, and the impeller assembly 312 is rotatably connected to the shaft 322 via the bearing 33. The bearing 33 can reduce the friction between the rotating part 31 and the shaft 322, improve the smoothness of the rotating part 31 during rotation, and reduce the vibration of the rotating part 31 during rotation by installing the bearing 33 on the impeller assembly 312, further improving the rotational stability of the rotating part 31.

[0063] Furthermore, the rotating part 31 also includes a primary filter 314, and the impeller assembly 312 is connected to the primary filter 314 and the secondary dust chamber 313 respectively. In other words, the impeller assembly 312 is located between the primary filter 314 and the secondary dust chamber 313 so that the airflow can drive the impeller assembly 312 to rotate. The impeller assembly 312 can stably drive the rotating part 31 to rotate, reducing the shaking of the rotating part 31 during the rotation process.

[0064] Additionally, the secondary filter 321 is located inside the primary filter 314. The primary filter 314 is located on the outside. The primary filter 314 can filter larger dust particles such as debris and hair, while the secondary filter 321 can filter smaller dust particles. For example, airflow containing dirt and dust enters the dust cup 21 from the air inlet 211. The filter device 30 filters the airflow. Larger debris such as debris and hair are first filtered by the primary filter 314 and intercepted on the outside of the primary filter 314. The secondary filter 321 further filters the airflow that has been filtered by the primary filter 314. The filtered clean airflow flows to the suction motor through the air outlet 212 of the dust cup 21. When the cup lid 22 opens the dust outlet 213, the rotating part 31 rotates around the axis, which can loosen the hair and other filaments wrapped around the surface of the primary filter 314, making it easier for the hair and other filaments to separate from the primary filter 314. This eliminates the need for an additional cleaning mechanism for the primary filter 314 and makes the filter device 30 less prone to clogging, allowing the vacuum cleaner 100 to maintain a good cleaning effect even after long-term use.

[0065] For example, the primary filter 314 may include a filter screen or sponge, etc., to perform primary filtration of dirt entering the dust cup 21. The secondary filter 321 is located inside the primary filter 314. The secondary filter 321 may include a HEPA filter or a multi-cone cyclone separator, etc. The secondary filter 321 is located downstream of the primary filter 314 and can perform secondary filtration of the airflow filtered by the primary filter 314.

[0066] According to a second aspect embodiment of the present invention, a vacuum cleaner 100 includes: a main unit 10, a dust cup 21, a cup lid 22, and a filter device 30. The main unit 10 includes a suction device 11 and a flow guiding structure 12. The dust cup 21 includes an air inlet 211, an air outlet 212, and a dust discharge port 213. The cup lid 22 is closably disposed at the dust discharge port 213. At least a portion of the filter device 30 extends into the dust cup 21. The filter device 30 includes a rotating part 31 and a fixed part 32. The rotating part 31 has a rotating state and a non-rotating state. The axis of the suction device 11 is parallel to the axis of the rotating part 31. In the non-rotating state, the airflow in the dust cup 21 enters the inner side of the rotating part 31 from the outside of the rotating part 31 and flows to the suction device 11 from the air outlet 212. In the rotating state, the flow guiding structure 12 restricts the airflow from the air outlet 212 to the inner side of the rotating part 31, and the rotating part 31 rotates under the influence of the airflow entering the dust cup 21 from the air inlet 211.

[0067] Specifically, combined Figure 4 and Figure 5 The axis of the rotating part 31 is A. When the rotation is stopped, the suction device 11 works. The airflow enters the inner side of the rotating part 31 from the outside and is discharged from the air outlet 212 through the suction device 11 to the outside of the vacuum cleaner 100. The axis of the suction device 11 is parallel to the axis of the rotating part 31, which can improve the suction efficiency of the suction device 11 and thus improve the effect of the vacuum cleaner 100.

[0068] In addition, the main unit 10 includes a flow guide structure 12. In the rotating state, the flow guide structure 12 restricts the airflow from the air outlet 212 into the inner side of the rotating part 31, which can avoid the airflow turbulence on the inner and outer sides of the rotating part 31 and improve the rotational stability of the rotating part 31 when airflow is introduced into the dust cup 21 through the air inlet 211.

[0069] It should be noted that the aforementioned different embodiments can be implemented individually, or multiple implementation methods can be combined to form a new technical solution without conflict.

[0070] Combination Figure 9 and Figure 10According to an embodiment of the present invention, a cleaning system 1000 includes: a motorless base station 200 and the aforementioned vacuum cleaner 100. The motorless base station 200 has a dust collection duct 220 and a bypass duct 230 that are interconnected. The vacuum cleaner 100 can be separated from and connected to the motorless base station 200. The vacuum cleaner 100 has an air inlet duct 14 and a self-cleaning duct 13. The vacuum cleaner 100 has a working mode and a self-cleaning mode. In the working mode, the air inlet duct 14 is fluidly connected to the dust cup 21, and the suction device 11 is fluidly connected to the inner cavity of the dust cup 21. In the self-cleaning mode, the air inlet duct 14 is fluidly connected to the dust cup 21, and the dust cup 21 is fluidly connected to the dust collection duct 220, and the bypass duct 230 is fluidly connected to the suction device 11.

[0071] Combination Figure 3 For example, the arrows indicate the airflow direction of the vacuum cleaner 100 in operating mode. In operating mode, the suction device 11 is fluidly connected to the inner cavity of the dust cup 21. Dust, hair, debris, and other contaminants from the working surface are drawn into the dust cup 21 through the air inlet duct 14. The cup cover 22 closes the dust discharge port, keeping the dust cup 21 in a sealed state. The filter device 30 filters the airflow, and the clean airflow after dust filtration is discharged from the suction device 11 through the air outlet 212 to the outside of the vacuum cleaner 100. Figure 10 After the vacuum cleaner 100 completes the cleaning work, it can be connected to the motorless base station 200. In the self-cleaning mode, the vacuum cleaner 100 opens the dust discharge port with the cup lid 22, so that the dust cup 21 is fluidly connected to the dust collection air duct 220, and the bypass air duct 230 is fluidly connected to the suction device 11. Under the action of the suction device 11, a negative pressure is generated in the motorless base station 200, so that the dust, debris, hair and other dirt in the dust cup 21 are collected into the dust bag 240 of the motorless base station 200. The airflow in the motorless base station 200 flows back to the self-cleaning air duct 13 of the vacuum cleaner 100 through the bypass air duct 230, and finally is discharged from the suction device 11. By setting a bypass ventilation duct 230 on the motorless base station 200 and a self-cleaning air duct 13 on the vacuum cleaner 100, the motorless base station 200 does not need to be equipped with a motor. By using the suction device 11 of the vacuum cleaner 100, a negative pressure is generated inside the motorless base station 200. The negative pressure inside the motorless base station 200 can clean and collect dirt from the dust cup 21 of the vacuum cleaner 100, simplifying the structure of the motorless base station 200 and reducing the noise of the motorless base station 200 during operation.

[0072] Combination Figure 10Furthermore, in self-cleaning mode, airflow flows along the air inlet duct 14, dust cup 21, dust collection duct 220, bypass duct 230, self-cleaning duct 13, and suction device 11, driving the rotating part 31 to rotate. That is, the airflow entering the dust cup 21 in self-cleaning mode can be used to drive the rotating part 31 to rotate. Specifically, in working mode, when the dust-laden airflow enters the dust cup 21 through the air inlet duct 14, a high-speed rotating airflow is formed inside the dust cup 21. Hair and other filamentous materials are easily wrapped around the outside of the rotating part 31. However, when the vacuum cleaner 100 is in self-cleaning mode, the rotating part 31 is rotating. The airflow entering the dust cup 21 through the air inlet duct 14 can drive the rotating part 31 to rotate, so that the hair and other filamentous materials wrapped around the rotating part 31 in working mode can be loosened, and the filamentous materials are easier to fall off. The rotating part 31 is driven by the airflow entering the dust cup 21. Therefore, its rotation direction is the same as the rotation direction of the airflow entering the dust cup 21, and thus also the same as the direction in which the hair rotates and wraps around the airflow. Compared to the case where the rotating part 31 does not rotate, when the airflow rotates a certain number of times in the dust cup 21, the hair theoretically rotates less relative to the rotating part 31 when the rotating part 31 rotates, that is, the number of times the hair wraps around is also lower. Therefore, it is more conducive to the separation of hair from the rotating part 31. In the self-cleaning mode, the vacuum cleaner 100 can improve the cleaning effect on the filter device 30 without the need to set up a separate structure for cleaning the filter device 30, thereby reducing the situation where hair wraps around and clogs the filter device 30, affecting the filtration efficiency.
