[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 cleaning device 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

[0042] 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.

[0043] During cleaning, dirty air drawn in by the vacuum head enters the dust cup through the air inlet. When the cleaning device sucks in longer hairs, based on the principle of a cyclone separator, the airflow causes the hair to rotate around the filter. After prolonged use, these 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, complicating the overall structure, increasing the weight of the machine, and affecting 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 failure, also increasing costs. Therefore, this invention proposes a cleaning device that improves the structure of the filter device, making it easier to clean the dirt entangled on the filter surface.

[0044] Combination Figure 1 and Figure 2The cleaning device 100 according to an embodiment of the present invention includes: a main unit 10, a dust cup assembly 20, and a filter device 30. The main unit 10 includes a suction motor 11; the dust cup assembly 20 includes a dust cup 21 and a cup lid 22. The dust cup 21 has an air inlet 211, an air outlet 212, and a dust discharge port 213; the cup lid 22 is connected to the dust cup 21 and can open and close the dust discharge port 213; at least a portion of the filter device 30 extends into the dust cup 21. Specifically, during operation, the cup lid 22 closes the dust discharge port 213, and the suction motor 11 can provide negative pressure. Under the action of negative pressure, the cleaning device 100 can draw dust, hair, and other dirt from the work 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 motor 11 to the outside of the cleaning device 100. When it is necessary to clean the dirt in the dust cup assembly 20, the dust discharge port 213 is opened through the cup lid 22.

[0045] For example, the air inlet 211 may be located on the side wall of the dust cup 21, and the cleaning device 100 may also include an air suction pipe, which can be connected to the dust cup 21 through the air inlet 211.

[0046] Combination Figure 2 The filter device 30 includes a rotating part 31 and a fixing part 32, wherein the filter device 30 can be fixed to the main unit 10. It is understood that the dust cup assembly 20 and the main unit 10 are typically detachably connected. When the dust cup assembly 20 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 assembly 20. When the dust cup assembly 20 is separated from the main unit 10, the filter device 30 can still be connected to the main unit 10. When the dust cup assembly 20 needs to be replaced or cleaned, disassembly of the dust cup assembly 20 is more convenient, improving the efficiency of disassembly and assembly. Furthermore, the filter device 30 is connected to the main unit 10 through the fixing part 32, making the structure of the filter device 30 more stable, improving the working stability of the filter device 30, and reducing the impact of the dust cup assembly 20 on the filter device 30 during disassembly and assembly. The filter device 30 can be fixedly connected to the main unit 10 via a detachable connection method, such as by means of rotational snap-fit. Furthermore, the filter device 30 can be connected to the main unit 10 via a fixing part 32.

[0047] In another embodiment, the filter device 30 may also be fixed to the dust cup assembly 20. When the dust cup assembly 20 is disassembled, the filter device 30 and the dust cup assembly 20 are separated from the main unit 10 together.

[0048] It should be noted that the filter device 30 is connected to the main unit 10 through the fixing part 32. The fixing part 32 and the main unit 10 can be detachably connected. For example, the upper end of the fixing part 32 can be provided with a snap-fit ​​groove, and the main unit 10 can 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. The filter device 30 is located upstream of the suction fan. The detachable connection between the filter device 30 and the main unit 10 facilitates the maintenance of the filter device 30.

[0049] The rotating part 31 is rotatable relative to the fixed part 32. Understandably, when the cleaning equipment 100 is in operation, the dust-laden airflow enters the dust cup assembly 20, forming a high-speed rotating airflow within the dust cup assembly 20. 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 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 filaments from the filter device 30. This eliminates the need for an additional cleaning mechanism for the filter device 30 and prevents blockage, allowing the cleaning equipment 100 to maintain a good cleaning effect even after prolonged use. Furthermore, the rotating part 31 is rotatably connected to the fixed part 32. As mentioned above, since the fixed part 32 is connected to the main unit 10, its structure is more stable, allowing it to better support the rotation of the rotating part 31, thus making the rotation of the rotating part 31 more stable.

[0050] Combination Figure 2 The rotating part 31 includes a first rotating connector 311 and a second rotating connector 312 connected to the fixed part 32. The first rotating connector 311 and the second rotating connector 312 are arranged along the axis of the rotating part 31 (axis A). When the cup lid 22 opens the dust outlet 213, the distance between the first rotating connector 311 and the second rotating connector 312 is greater than the distance between the first rotating connector 311 and the second rotating connector 312 when the cup lid 22 closes the dust outlet 213. Figures 3 to 6When the dust outlet 213 is closed on the cup lid 22, the distance between the first rotating connector 311 and the second rotating connector 312 is d1. When the dust outlet 213 is open on the cup lid 22, the distance between the first rotating connector 311 and the second rotating connector 312 is d2, where d2 > d1. Specifically, the fixing part 32 is connected to the main unit 10, and the position of the fixing part 32 is relatively fixed. The rotating part 31 is rotatably connected to the fixing part 32 through the first rotating connector 311 and the second rotating connector 312. The first rotating connector 311 and the second rotating connector 312 can support the rotation of the rotating part 31. When the dust outlet 213 is closed, the distance between the first rotating connector 311 and the second rotating connector 312 is smaller, making the structure of the cleaning device 100 more compact. When the dust outlet 213 is opened by the cup lid 22, the distance between the first rotating connector 311 and the second rotating connector 312 increases, which can reduce the shaking and vibration of the rotating part 31 during rotation, improve the stability of the rotating part 31 during rotation, and facilitate the stable loosening of hair wrapped around the filter device 30 during rotation, thereby improving the cleaning efficiency of the filter device 30 and reducing the noise of the rotating part 31 during rotation.

[0051] According to the cleaning device 100 of this utility model embodiment, the filter device 30 further includes a rotating part 31. The rotating part 31 rotates relative to the fixed part 32 to loosen the hair wrapped around the filter device 30, making it easier to clean the filter device 30. When the cup lid 22 opens the dust discharge port 213, the distance between the first rotating connector 311 and the second rotating connector 312 increases, which can reduce the shaking and vibration of the rotating part 31 during rotation, improve the stability of the rotating part 31 during rotation, and thus improve the cleaning effect on the filter device 30.

[0052] When the dust outlet 213 is closed by the cup lid 22, the rotating part 31 can be locked by the fixing part 32 or the cup lid 22, preventing the rotating part 31 from rotating. This allows the filter device 30 to filter the dust entering the dust cup assembly 20, ensuring the filtration effect of the filter device 30. When the dust outlet 213 is open by the cup lid 22, the rotating part 31 can rotate relative to the fixing part 32 to loosen hair entangled on the filter device 30. Specifically, the rotating part 31 can have a rotating position and a non-rotating position. When the cup lid 22 is closed, the rotating part 31 can be in the non-rotating position, and the rotating part 31 and the fixing part 32 are relatively stationary. When the cup lid 22 is open, the rotating part 31 can be in the rotating position, and the rotating part 31 can rotate relative to the fixing part 32. For example, the rotating position can be located below the anti-rotation position. In other words, the rotating part 31 can move up and down along the axial direction. When the cup lid 22 is closed, the cup lid 22 abuts against the rotating part 31 to prevent the rotating part 31 from rotating. When the cup lid 22 is open, the cup lid 22 releases its abutment against the rotating part 31, allowing the rotating part 31 to move downward and rotate relative to the fixed part 32.

[0053] For example, the cleaning device 100 can be connected to the base station 200 to clean the dirt in the dust cup 21 through the base station 200, reducing the user's operational burden. The cleaning device 100 can have a working state and a cleaning state. In the working state, the cup cover 22 closes the dust outlet 213 and the rotating part 31 is in a stopped position. The filter device 30 filters the airflow entering the dust cup 21. At this time, the rotating part 31 and the fixed part 32 can be relatively stationary to ensure the filtration effect of the filter device 30. After the cleaning device 100 is connected to the base station 200, in the cleaning state, the cup cover 22 opens the dust outlet 213 and the rotating part 31 is in a rotating position. The rotating part 31 can rotate to loosen the hair wrapped around the surface of the filter device 30, thereby achieving a good cleaning effect for long hair wrapped around the filter device 30. The rotating part 31 can be driven to rotate directly by a drive structure such as a motor installed on the cleaning device 100 or the base station 200; or the rotating part 31 can be driven to rotate by the airflow introduced from the air inlet 211 of the dust cup 21.

[0054] Additionally, the cup lid 22 can open and close the dust exhaust port 213. For example, the base station 200 may be provided with an unlocking component. After the cleaning device 100 is connected to the base station 200, the unlocking component can trigger the opening of the dust exhaust port 213 of the cup lid 22. That is, the dust exhaust port 213 can be opened by a mechanical structure. Alternatively, in the self-cleaning state, the cleaning device 100, under the action of the motor, generates negative pressure in the base station 200, and the dust exhaust port 213 is opened under the action of negative pressure.

[0055] For example, the first rotating connector 311 and the second rotating connector 312 can be bearings, which can reduce the friction between the rotating part 31 and the fixed part 32, improve the smoothness of the rotating part 31 during rotation, and reduce the vibration of the rotating part 31 during rotation.

[0056] The first rotary connector 311 and the second rotary connector 312 are connected to the fixed part 32. The first rotary connector 311 and the second rotary connector 312 may be provided at the upper end of the fixed part 32; or the first rotary connector 311 and the second rotary connector 312 may be provided at the lower end of the fixed part 32; or the first rotary connector 311 may be provided at the upper end of the fixed part 32 and the second rotary connector 312 may be provided at the lower end of the fixed part 32.

[0057] Furthermore, when the cup lid 22 opens the dust outlet 213, the distance between the first rotating connector 311 and the second rotating connector 312 is greater than the distance between the first rotating connector 311 and the second rotating connector 312 when the cup lid 22 closes the dust outlet 213. For example, the position of the first rotating connector 311 in the axial direction can be relatively fixed, and the second rotating connector 312 moves along the axis when the cup lid 22 opens and closes the dust outlet 213; or, the position of the second rotating connector 312 in the axial direction can be relatively fixed, and the first rotating connector 311 moves along the axis when the cup lid 22 opens and closes the dust outlet 213. The first rotating connector 311 and the fixing part 32 can be in a clearance fit, and the second rotating connector 312 and the fixing part 32 can also be in a clearance fit.

[0058] For example, an elastic element 33 may be provided between the first rotary connector 311 and the second rotary connector 312. After the cup lid 22 opens the dust outlet 213, the elastic element 33 drives the distance between the first rotary connector 311 and the second rotary connector 312 to increase. Alternatively, the filter device 30 includes a top rod. For example, the top rod may be connected to the second rotary connector 312 and opposite to the cup lid 22. When the cup lid 22 opens and closes the dust outlet 213, the top rod drives the second rotary connector 312 to slide in the up and down direction, thereby increasing the distance between the first rotary connector 311 and the second rotary connector 312.

[0059] Combination Figure 4 and Figure 6 In some embodiments of this utility model, the filter device 30 further includes an elastic element 33, which is elastically supported between the first rotary connector 311 and the second rotary connector 312. When the cup lid 22 opens the dust outlet 213, it drives the distance between the first rotary connector 311 and the second rotary connector 312 to increase. By providing the elastic element 33 between the first rotary connector 311 and the second rotary connector 312, the structure of the filter device 30 is simplified.

[0060] For example, when the cup lid 22 closes the dust outlet 213, the cup lid 22 can simultaneously stop the rotating part 31, making the distance between the first rotating connector 311 and the second rotating connector 312 smaller, and the structure of the filter device 30 more compact. When the cleaning device 100 is in the cleaning state, the cup lid 22 opens the dust outlet 213, the cup lid 22 releases the rotating part 31, and the elastic member 33 drives the distance between the first rotating connector 311 and the second rotating connector 312 along the axis to increase. The first rotating connector 311 and the second rotating connector 312 cooperate to stably support the rotating part 31 to rotate.

[0061] In some embodiments of this invention, at least a portion of the fixing part 32 is located within the rotating part 31. Specifically, the upper end of the fixing part 32 may extend out of the rotating part 31 to facilitate connecting the filter device 30 to the main unit 10 via the fixing part 32. A portion of the fixing part 32 is located within the rotating part 31, making the overall structure of the filter device 30 more compact. Furthermore, since hair and other debris are typically wrapped around the outside of the filter device 30, the rotating part 31 can loosen the hair wrapped around the outside of the filter device 30 during rotation. Alternatively, the entire fixing part 32 may be located inside the rotating part 31.

[0062] Combination Figure 3 In some embodiments of this utility model, the rotating part 31 includes a primary filter 313, and the fixing part 32 includes a secondary filter 321, which is disposed inside the primary filter 313. The primary filter 313 is disposed on the outside. The primary filter 313 can filter larger dust particles such as debris, hair, and other dirt, while the secondary filter 321 can filter smaller dust particles. Exemplarily, airflow containing dirt and dust enters the dust cup 21 from the air inlet 211. The filtering device 30 filters the airflow. Larger dirt such as debris and hair is first filtered by the primary filter 313 and intercepted on the outside of the primary filter 313. The secondary filter 321 further filters the airflow after it has been filtered by the primary filter 313. The filtered clean airflow flows to the suction motor 11 through the air outlet 212 of the dust cup 21. Figure 5 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 313, making it easier for the hair and other filaments to separate from the primary filter 313. There is no need to set up an additional cleaning mechanism for cleaning the primary filter 313, and the filter device 30 is not easily clogged, so that the cleaning equipment 100 can still maintain a good cleaning effect after long-term use.

[0063] For example, the primary filter 313 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 313. 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 313 and can perform secondary filtration of the airflow filtered by the primary filter 313.

[0064] Combination Figure 3 and Figure 7In some embodiments of this utility model, the rotating part 31 includes a primary filter 313 and a rotating bracket 314. The rotating bracket 314 is rotatably connected to the fixing part 32. The primary filter 313 is connected to the rotating bracket 314. A secondary dust collection part 3141 is constructed inside the rotating bracket 314. The fixing part 32 includes a secondary filter 321 and a support frame 322. The support frame 322 is connected to the main unit 10. The secondary filter 321 is connected to the support frame 322. The secondary filter 321 is disposed inside the primary filter 313 and above the secondary dust collection part 3141. The support frame 322 is used to connect the filter device 30 to the main unit 10. Additionally, the support frame 322 is used to fix and support the secondary filter 321, improving the structural stability of the secondary filter 321. Specifically, during the operation of the cleaning device 100, hair and other debris can easily become entangled on the outer surface of the primary filter 313. The rotating bracket 314 is rotatably connected to the fixed part 32 to support the rotation of the primary filter 313, so as to loosen the hair entangled on the surface of the primary filter 313. In addition, a secondary dust collection part 3141 is constructed on the inner side of the rotating bracket 314. The secondary dust collection part 3141 can be used to collect the dust filtered by the secondary filter 321, making the structure of the filter device 30 more compact.

[0065] In some embodiments of this utility model, the rotating bracket 314 has a mounting cavity 3142, and the fixing part 32 includes a support shaft 323 passing through the mounting cavity 3142 along its axis. A first rotating connector 311 is sleeved between the peripheral wall of the mounting cavity 3142 and the support shaft 323, and a second rotating connector 312 is sleeved between the peripheral wall of the mounting cavity 3142 and the support shaft 323. By providing a mounting cavity 3142 in the rotating bracket 314, the space of the rotating bracket 314 is fully utilized, and the first rotating connector 311 and the second rotating connector 312 are placed in the mounting cavity 3142, avoiding any impact on the structure of the primary filter 313 and the secondary filter 321.

[0066] For example, the support shaft 323 can be connected to the support frame 322, which is fixed to the host 11. The structure of the support frame 322 is more stable, which makes it easier for the support shaft 323 to support the rotating part 31 to rotate stably.

[0067] Combination Figure 7 Optionally, the support frame 322 may include an upper support 3221 and a lower support 3222 connected together. The secondary filter 321 is sandwiched between the upper support 3221 and the lower support 3222. The upper support 3221 is connected to the main unit 10, and the support shaft 323 is connected to the lower support 3222, which facilitates the installation of the filter device 30 and makes the structure of the filter device 30 compact.

[0068] The support shaft 323 is a fixed structure. The inner ring of the first rotating connector 311 can be clearance-fitted with the support shaft 323, and the inner ring of the second rotating connector 312 can be clearance-fitted with the support shaft 323, so that when the cup lid 22 is opened and closed, the first rotating connector 311 or the second rotating connector 312 can slide relative to the support shaft 323 along the axial direction.

[0069] Combination Figure 4 and Figure 6 In some embodiments of this utility model, the mounting cavity 3142 has a first limiting portion 3143 and a second limiting portion 3144 distributed along the axis, and the first rotary connector 311 and the second rotary connector 312 are limited between the first limiting portion 3143 and the second limiting portion 3144; the support shaft 323 has a third limiting portion 3231 and a fourth limiting portion 3232 distributed along the axis, and the first rotary connector 311 and the second rotary connector 312 are limited between the third limiting portion 3231 and the fourth limiting portion 3232. For example, the third limiting portion 3231 limits the first rotary connector 311, and the second limiting portion 3144 limits the second rotary connector 312. When the cup lid 22 closes the dust outlet 213, the first rotating connector 311 and the second rotating connector 312 are confined between the third limiting part 3231 and the second limiting part 3144. When the cup lid 22 opens the dust outlet 213, the first limiting part 3143 and the fourth limiting part 3232 cooperate to restrict the downward movement of the second rotating connector 312. Through the cooperation of the first limiting part 3143, the second limiting part 3144, the third limiting part 3231, and the fourth limiting part 3232, the stroke of the first rotating connector 311 and the second rotating connector 312 is limited, preventing the first rotating connector 311 and the second rotating connector 312 from disengaging from the mounting cavity 3142 when the cup lid 22 opens and closes the dust outlet 213, thereby allowing the first rotating connector 311 and the second rotating connector 312 to stably support the rotation of the rotating part 31.

[0070] In some embodiments of this utility model, the second rotating connector 312 is disposed below the first rotating connector 311. The outer ring of the first rotating connector 311 is clearance-fitted with the peripheral wall of the mounting cavity 3142, and the second rotating connector 312 is interference-fitted with the peripheral wall of the mounting cavity 3142. The rotating part 31 has a rotating position and a non-rotating position. In the rotating position, the second rotating connector 312 stops the fourth limiting part 3232. In the non-rotating position, the cup cover 22 closes the dust discharge port 213, and the cup cover 22 stops the rotating part 31 and restricts the rotation of the rotating part 31.

[0071] Specifically, when the cup lid 22 is closed, the rotating part 31 is in the anti-rotation position. The cup lid 22 stops the rotating part 31 and restricts its rotation. The rotating part 31 cannot rotate, which facilitates the filtering device 30 to filter the airflow entering the dust cup 21. After the cleaning device 100 is connected to the base station 200, the cup lid 22 can be opened, the rotating part 31 is in the rotating position, and the distance between the first rotating connector 311 and the second rotating connector 312 increases. The second rotating connector 312 stops the fourth limiting part 3232, which can limit the rotation of the rotating part 31.

[0072] For example, the rotating position can be located above the anti-rotation position, and the rotating part 31 can move up and down along the axial direction. An elastic member 33 can be provided between the first rotating connector 311 and the second rotating connector 312. When the cup lid 22 is closed, the rotating part 31 is in the anti-rotation position, and the rotating bracket 314 can abut against the cup lid 22. The primary filter 313 contacts and cooperates with the fixed part 32. That is, when the cup lid 22 closes the dust discharge port 213, the rotating part 31 cannot rotate or move under the action of the cup lid 22 and the fixed part 32. When the cup lid 22 opens the dust discharge port 213, the cup lid 212 can move up and down. 2. Release the rotating part 31. The rotating part 31 can move downward under the action of gravity and elastic member 33, giving the second rotating connector 312 a downward loosening force, increasing the distance between the first rotating connector 311 and the second rotating connector 312. At this time, the fourth limiting part 3232 can limit the second rotating connector 312 and the rotating bracket 314 to prevent the rotating part 31 from moving too far downward. At the same time, after the cup lid 22 releases the rotating part 31, the rotating part 31 can be driven to rotate by the airflow entering the dust cup 21 to loosen the hair wrapped around the surface of the filter device 30.

[0073] Combination Figure 4 In some embodiments of this utility model, the peripheral wall of the mounting cavity 3142 has a guide slope 3142a extending in the vertical direction, and the guide slope 3142a gradually narrows from top to bottom. Exemplarily, the mounting cavity 3142 can be configured as a structure that is narrower at the bottom and wider at the top, connected in the middle by the guide slope 3142a, so that the outer ring of the second rotating connector 312 is in an interference fit with the peripheral wall of the mounting cavity 3142, and the outer ring of the first rotating connector 311 is in a clearance fit with the peripheral wall of the mounting cavity 3142. Simultaneously, the guide slope 3142a facilitates the installation of the second rotating connector 312.

[0074] In some embodiments of this utility model, the distance between the first limiting part 3143 and the second limiting part 3144 is greater than or equal to the distance between the third limiting part 3231 and the fourth limiting part 3232. The greater distance between the first limiting part 3143 and the second limiting part 3144 allows for a greater distance between the first rotating connector 311 and the second rotating connector 312 when the rotating part 31 moves along the axis. This facilitates better cooperation between the first rotating connector 311 and the second rotating connector 312 to support the rotation of the rotating part 31 when the dust outlet 213 is opened on the cup lid 22.

[0075] Combination Figure 6 In some embodiments of this utility model, the fourth limiting part 3232 is provided with a buffer pad 3233. After the cup lid 22 opens the dust discharge port 213, the position of the buffer pad 3233 is relatively fixed, and the second rotating connector 312 can move downward. The buffer pad 3233 can reduce the friction between the second rotating connector 312 and the fourth limiting part 3232 after it descends, thereby playing a role in shock absorption and noise reduction.

[0076] Combination Figure 4 and Figure 7 For example, the first limiting part 3143 may be a cover plate covering the mounting cavity 3142. In addition, the mounting cavity 3142 may be provided with a first positioning groove, and the second limiting part 3144 may be a first step provided in the first positioning groove. The support shaft 323 may be provided with a second positioning groove, and the third limiting part 3231 may be a second step provided in the second positioning groove. In addition, the lower end of the support part may be provided with a screw, and the fourth limiting part 3232 may be a screw.

[0077] Combination Figure 5 and Figure 7 In some embodiments of this invention, the rotating part 31 includes blades 315, which are adapted to be driven by airflow flowing from the air inlet 211 to the dust outlet 213. For example, when the cleaning device 100 is in a cleaning state, the base station 200 can generate negative pressure, driving airflow from the air inlet 211 to the dust outlet 213 to collect dirt from the dust cup 21 into the base station 200. By using the airflow entering the dust cup 21 to drive the blades 315 to rotate, the rotating part 31 can be rotated. That is, there is no need to separately set up a drive structure to drive the rotating part 31 to rotate; the airflow entering the dust cup 21 can directly drive the rotating part 31 to rotate, simplifying the structure of the cleaning device 100. Furthermore, the blades 315 can improve the rotation efficiency of the rotating part 31.

[0078] The blades 315 may include a plurality of blades arranged in a circumferential direction. For example, the rotating part 31 may include a primary filter 313 and a rotating support 314, the rotating support 314 being provided with blades 315. Additionally, the primary filter 313 may include a filter screen and a filter screen support, the filter screen support surrounding the axis of the rotating part 31 and having a perforated structure, the filter screen being disposed on the filter screen support and covering the perforated structure, the filter screen support being provided with blades 315.

[0079] In addition, blades 315 are provided in the rotating part 31, which can drive the rotating part 31 to rotate under the action of airflow, and can also prevent hair and other objects from getting tangled in the filter device 30.

[0080] In some embodiments of this invention, at least a portion of the blade 315 extends along an axial direction. Exemplarily, the entire blade 315 may extend along an axial direction; or, a portion of the blade 315 may extend along an axial direction, while another portion forms an angle with the axis. The extension of at least a portion of the blade 315 along an axial direction ensures that the normal of the blade 315 is parallel to the airflow direction, optimizing the pushing effect of the airflow on the blade 315 and thereby improving the hair removal efficiency.

[0081] In some embodiments of this utility model, at least a portion of the blade 315 has an angle with the axis, and the angle is less than 90°, so that the airflow can act on the blade 315, drive the blade 315 to rotate, and thus stably drive the rotating part 31 to rotate.

[0082] Preferably, the included angle is less than 45° to enhance the propulsive effect of the airflow on the blade 315.

[0083] In some embodiments of this utility model, the blade 315 is arranged opposite to the air inlet 211 so that the airflow through the air inlet 211 drives the blade 315 to rotate, thereby further enhancing the driving effect of the airflow on the blade 315.

[0084] Combination Figure 3In some embodiments of this utility model, the rotating part 31 includes a primary filter 313, and the fixing part 32 includes a secondary filter 321. When the cup lid 22 is closed, the fixing part 32 is sealed to the upper edge of the primary filter 313 and the lower edge of the primary filter 313. The secondary filter 321 has an inlet connecting the space between the primary filter 313 and the secondary filter 321. Specifically, during the operation of the cleaning device 100, the cup lid 22 closes the dust discharge port 213, and the filtering device 30 filters the dust entering the dust cup assembly 20. The dust-laden airflow is first filtered by the primary filter 313 and then enters the space between the primary filter 313 and the secondary filter 321. It enters the secondary filter 321 from the inlet for filtration. The fixing part 32 is sealed to the upper and lower edges of the primary filter 313, which can play a role in blocking dust and preventing larger dust particles from entering the space between the primary filter 313 and the secondary filter 321 without being filtered by the primary filter 313.

[0085] For example, one of the fixing part 32 and the primary filter 313 is provided with a positioning groove, and the other is provided with a baffle. When the cup lid 22 closes the dust discharge port 213, the baffle extends into the positioning groove to seal the gap between the fixing part 32 and the primary filter 313, thereby extending the path that dust takes when passing through the gap and increasing the difficulty for dust to pass through the gap.

[0086] In addition, a sealing ring can be provided in the positioning groove. When the cup lid 22 is closed, the baffle can abut against the sealing ring, which can further improve the sealing effect.

[0087] Combination Figure 3 In some embodiments of this utility model, the cup lid 22 is provided with a damping member 221. When the cup lid 22 closes the dust outlet 213, the damping member 221 stops the rotating part 31 and restricts its rotation. When the cup lid 22 opens the dust outlet 213, the damping member 221 releases the restriction on the rotation of the rotating part 31. Specifically, the damping member 221 can be connected to the side of the cup lid 22 facing the dust cup 21. When the cup lid 22 closes the dust outlet 213, the damping member 221 presses the rotating part 31 upward, preventing it from rotating. This allows the filter device 30 to filter the dust-laden airflow entering the dust cup assembly 20, preventing the rotation of the rotating part 31 from affecting the filtration effect of the filter device 30. For example, the damping member 221 can be a rubber component.

[0088] In some embodiments of this utility model, when the cup lid 22 closes the dust outlet 213, the fixing part 32 and the rotating part 31 engage in a stop-and-resist engagement, restricting the rotation of the rotating part 31. Specifically, when the cup lid 22 closes the dust outlet 213, the fixing part 32 contacts the rotating part 31 and applies a force to the rotating part 31, restricting its rotation and keeping the fixing part 32 and the rotating part 31 relatively stationary. This allows the filter device 30 to filter the dust-laden airflow entering the dust cup assembly 20, preventing the rotation of the rotating part 31 from affecting the filtration effect of the filter device 30.

[0089] In some embodiments of this utility model, the cup lid 22 is provided with a damping member 221. When the cup lid 22 closes the dust outlet 213, the damping member 221 stops the rotating part 31 and restricts the rotation of the rotating part 31. The fixing part 32 stops the rotating part 31 and restricts the rotation of the rotating part 31. At this time, since the cup lid 22 is closed, the damping member 221 on the cup lid 22 presses the rotating part 31 upward, so that the upper end of the rotating part 31 abuts against the fixing part 32 and the lower end of the rotating part 31 abuts against the damping member 221, thereby fixing the rotating part 31 and preventing it from rotating, improving the structural stability of the rotating part 31 when the cup lid 22 is closed, and thus improving the working stability of the cleaning equipment 100 during the dust collection process.

[0090] Combination Figure 2 and Figure 8 The cleaning system according to the present utility model includes: a base station 200 and the aforementioned cleaning device 100. The base station 200 has a docking interface 210. The dust cup assembly 20 is separable from and dockable with the docking interface 210. The cleaning device 100 has a working state and a cleaning state. In the working state, the cup cover 22 closes the dust discharge port 213, and the rotating part 31 and the fixed part 32 are relatively stationary. In the cleaning state, the cup cover 22 opens the dust discharge port 213, and the rotating part 31 can rotate.

[0091] Specifically, when the cleaning device 100 is in operation, the rotating part 31 and the fixed part 32 are relatively stationary, which facilitates the filtration device 30 to filter the airflow entering the dust cup 21, thereby improving the working stability of the cleaning device 100. When the cleaning device 100 can be connected to the base station 200 and passes through the dirt in the dust cup 21 of the base station 200, the cleaning device 100 is in a clean state when connected to the base station 200. The cup cover 22 opens the dust discharge port 213, and the rotating part 31 rotates to loosen the tangled hair, thereby facilitating the separation of hair from the filtration device 30, improving the cleaning effect on the filtration device 30, making the filtration device 30 less prone to clogging, and the cleaning device 100 can still maintain a good cleaning effect after long-term use.

[0092] Furthermore, the interface 210 can have negative pressure to drive the cup lid 22 to open the dust outlet 213, and the rotating part 31 rotates under the action of airflow. That is to say, there is no need to set up a separate structure to drive the rotating part 31 to rotate. The rotating part 31 is directly driven to rotate by the airflow entering the dust cup 21, which simplifies the structure of the cleaning equipment 100.

[0093] Optionally, the base station 200 has a dust collection duct and a bypass duct that are interconnected; the cleaning device 100 has an air inlet duct and a return duct, wherein, in the working state, the air inlet duct of the cleaning device 100 is connected to the dust cup 21, and the dust cup 21 is connected to the suction motor 11; in the cleaning state, the air inlet duct is connected to the dust cup 21, and the dust cup 21 is connected to the dust collection duct, and the bypass duct is connected to the suction motor 11.

[0094] For example, in the working state, the suction motor 11 is connected to the dust cup 21. Dust, hair, debris, and other contaminants from the working surface are sucked into the dust cup 21 through the air inlet duct. The cup cover 22 closes the dust outlet 213, 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 to the outside of the cleaning equipment 100 via the suction motor 11. After the cleaning equipment 100 completes the cleaning work, it can be connected to the base station 200. In the cleaning state, the cup cover 22 opens the dust outlet 213, connecting the dust cup 21 to the dust collection duct, and the bypass duct is connected to the return duct. Under the action of the suction motor 11, a negative pressure is generated inside the base station 200, causing the dust, debris, hair, and other contaminants in the dust cup 21 to be collected into the dust bag of the base station 200. The airflow inside the base station 200 flows back to the return duct of the cleaning equipment 100 via the bypass duct, and finally is discharged to the outside of the cleaning equipment 100 via the suction motor 11. By setting a bypass ventilation duct on the base station 200 and a return air duct on the cleaning device 100, the base station 200 does not need to be equipped with a motor. By using the suction motor 11 of the cleaning device 100 to introduce negative pressure into the base station 200, a negative pressure is generated inside the base station 200. The negative pressure inside the base station 200 can clean and collect dirt from the dust cup 21 of the cleaning device 100, simplifying the structure of the base station 200 and reducing the noise of the base station 200 during operation.

[0095] In the working state, the cup lid 22 closes the dust outlet 213. The cup lid 22 may be provided with a damping upward pressing rotating part 31, so that the upper end of the rotating part 31 abuts against the fixed part 32, and the lower end of the rotating part 31 abuts against the damping member 221, thereby being fixed and not rotating. The filter device 30 can filter the airflow entering the dust cup 21.

[0096] Furthermore, in the clean state, the airflow flows along the inlet air duct, dust cup 21, dust collection air duct, bypass air duct, and return air duct, driving the rotating part 31 to rotate. That is, the airflow entering the dust cup 21 in the clean state can be used to drive the rotating part 31 to rotate. Specifically, in the working state, when the dust-laden airflow enters the dust cup 21 through the inlet air duct, 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 filter device 30. However, when the cleaning device 100 is in the clean state, the damping member 221 of the cup cover 22 no longer abuts against the lower end of the rotating part 31. The rotating part 31 can slide downward under its own weight and the elastic force of the elastic member 33 and is supported by the screw of the fixing part 32. The rotating part 31 can rotate and loosen the wrapped hair under the action of the airflow inside the dust cup 21, making it easier for the hair 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 also the same as the direction in which the hair rotates and wraps around the airflow. When the rotating part 31 rotates a certain number of times along the direction of hair wrapping, compared with the case where the rotating part 31 does not rotate, the hair is more likely to loosen from the surface of the filter device 30 and be collected by the base station 200 under the negative pressure of the interface 210, thereby reducing the situation where hair wrapping and clogging the filter device 30 affects the filtration efficiency.
