Detailed Implementation

[0047] 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.

[0048] Combination Figures 1 to 5 The cleaning device 100 according to an embodiment of the present invention includes: a dust cup 10, a lid 11, and a filter device 20. The lower end of the dust cup 10 has an opening 13, through which material inside the dust cup 10 can be discharged. The lid 11 is used to open and close the opening 13. When the lid 11 opens the opening 13, material inside the dust cup 10 can be discharged through the opening 13. When the lid 11 closes the opening 13, the material sucked up by the cleaning device 100 is stored inside the dust cup 10. At least a portion of the filter device 20 is located inside the dust cup 10 and is used to filter the air sucked into the dust cup 10.

[0049] The filter device 20 includes a rotatable first filter section 21 and a second filter section 22, at least part of which is disposed within the first filter section 21. The second filter section 22 can move up and down relative to the first filter section 21 along the axis of the first filter section 21. When the cup lid 11 closes the opening 13, the second filter section 22 moves up to the first position, and the gap between the upper end of the second filter section 22 and the upper end of the first filter section 21 is sealed, preventing air from flowing directly out of the filter device 20 from the gap between the first filter section 21 and the second filter section 22, thereby improving the filtration effect of the filter device 20.

[0050] In this application, the gap between the upper end of the second filter section 22 and the upper end of the first filter section 21 is the gap generated between the upper end of the second filter section 22 and the upper end of the first filter section 21 after the cup lid 11 opens the opening 13 and the second filter section 22 moves down to the second position. This gap can reduce the resistance experienced by the first filter section 21, allowing the first filter section 21 to rotate under the drive of airflow.

[0051] Furthermore, the first filter section 21 is rotatable relative to the second filter section 22, so as to loosen the hair and other filaments wrapped around the first filter section 21. The filaments are easier to fall off, and the dirt on the outer surface of the first filter section 21 is easier to clean. This achieves cleaning of the inside of the dust cup 10 and the first filter section 21 without the need for an additional cleaning mechanism for cleaning the first filter section 21. The structure is simpler and the cost is lower. Moreover, it makes the first filter section 21 less prone to clogging, and the cleaning device 100 can maintain a good cleaning effect continuously.

[0052] According to the cleaning device 100 of this utility model embodiment, by sealing the gap between the upper end of the second filter section 22 and the upper end of the first filter section 21, the overall structure of the filter device 20 is simple, while enhancing the sealing between the first filter section 21 and the second filter section 22, ensuring that air flows to the second filter section 22 after passing through the first filter section 21, and preventing air from flowing directly to the outside through the gap between the first filter section 21 and the second filter section 22, thereby improving the filtration efficiency of the filter device 20; at the same time, the first filter section 21 can be rotated to facilitate cleaning of hair and other filamentous materials wrapped around the outer surface of the first filter section 21, thereby achieving cleaning of the inside of the dust cup 10 and the first filter section 21.

[0053] In conjunction with the foregoing, the axis of the first filter section 21 is along the vertical direction (see Appendix). Figure 1 The second filter section 22 extends in the vertical direction and can move relative to the first filter section 21 in the vertical direction so as to move up to the first position and close the gap between the upper end of the first filter section 21 and the upper end of the second filter section 22.

[0054] Combination Figure 1 and Figure 2 In some embodiments, the filter device 20 further includes a bracket 23 supporting the first filter section 21 and the second filter section 22. In the first position, the upper end of the second filter section 22 is sealed with the bracket 23 to enhance the sealing between the second filter section 22 and the bracket 23.

[0055] For example, the upper end of the bracket 23 is provided with a sealing groove 2301 with the slot facing the second filter part 22, so that at least a part of the upper end of the first filter part 21 and the upper end of the second filter part 22 extends into the sealing groove 2301. When the second filter part 22 is in the first position, the upper end of the second filter part 22 abuts against the top wall of the sealing groove 2301 and seals the gap between the upper end of the second filter part 22 and the sealing groove 2301, preventing unfiltered air from flowing directly out of the filter device 20 from the gap between the second filter part 22 and the sealing groove 2301, thereby improving the filtration effect of the filter device 20.

[0056] In some embodiments, the cleaning device 100 further includes a first seal 30, which is disposed on the bracket 23 and / or the second filter section 22. In a first position, the first seal 30 closes the gap between the bracket 23 and the second filter section 22, thereby achieving a sealed fit between the second filter section 22 and the bracket 23.

[0057] In conjunction with the foregoing embodiments, the upper end of the bracket 23 is provided with a sealing groove 2301 with the slot facing the second filter section 22. The second filter section 22 may include a mounting section 221. The first sealing member 30 may be provided at the top wall of the sealing groove 2301. In the first position, the upper end of the mounting section 221 abuts against the first sealing member 30, so that the gap between the upper end of the mounting section 221 and the sealing groove 2301 is sealed. The air in the dust cup 10 can only flow out of the filter device 20 after being filtered by the first filter section 21 and the second filter section 22, thus preventing the air from flowing directly out of the filter device 20 from the gap between the second filter section 22 and the bracket 23, thereby optimizing the filtration performance of the filter device 20. At the same time, the use of a sealing member can reduce the wear caused by direct contact between the bracket 23 and the upper end of the mounting section 221, thereby extending the service life of the bracket 23 and the mounting section 221.

[0058] Optionally, the first sealing element 30 can be a rubber sealing ring. The rubber sealing ring has excellent elasticity and toughness, which can effectively prevent the leakage of liquid or gas. It also has good wear resistance and anti-aging properties, a long service life, and low production cost. Of course, the first sealing element 30 can also adopt other forms of structure. For example, a brush structure can be provided on the top of the bracket 23 to prevent dust from flowing out of the filter device 20 from the gap between the second filter part 22 and the bracket 23.

[0059] The cleaning device 100 of this utility model embodiment is mainly described by using the first sealing element 30 to close the gap between the bracket 23 and the second filter part 22, but this is not a limitation on the protection scope of this utility model.

[0060] Combination Figures 1 to 5In some embodiments, the bracket 23 includes a main support, a rotating support 232, and a telescopic support 233. The main support is connected to the dust cup 10 and is fixed in position relative to the dust cup 10; the rotating support 232 is rotatably connected to the main support; the telescopic support 233 is movably connected to the main support in the vertical direction, wherein the first filter part 21 is connected to the rotating support 232, allowing the first filter part 21 to rotate; the second filter part 22 is connected to the telescopic support 233, allowing the second filter part 22 to move vertically along the axis of the first filter part 21.

[0061] For example, the main support can be snapped together with the dust cup 10. The main support can be provided with a first snap 2313, and the inner side wall of the dust cup 10 can be provided with a first latch 12. When the main support is connected to the dust cup 10, the first snap 2313 is snapped into the first latch 12 to ensure that the relative position of the main support and the dust cup 10 is fixed. Of course, the main support can be provided with a first latch 12, and the inner side wall of the dust cup 10 can be provided with a first snap 2313.

[0062] Among them, combined Figure 1 , Figure 4 , Figure 6 and Figure 10 The rotating support 232 is rotatably connected to the lower part of the main support. The first filter part 21 includes a cylindrical bracket 211 and a filter screen 212. The cylindrical bracket 211 is located outside the second filter part 22, and the filter screen 212 is located on the cylindrical bracket 211. The lower end of the cylindrical bracket 211 is snapped to the rotating support 232. The cylindrical bracket 211 is provided with a second snap 2111. The rotating support 232 is provided with a corresponding slot 2325 inside. When the first filter part 21 is connected to the rotating support 232, the second snap 2111 is snapped into the slot 2325. The first filter part 21 is fixed relative to the rotating support 232. When the rotating support 232 rotates, it drives the first filter part 21 to rotate, which facilitates the cleaning of long and numerous impurities such as hair wrapped around the outside of the first filter part 21.

[0063] Additionally, the telescopic support 233 can be fixedly connected to the second filter section 22 via bolts 2331, and the telescopic support 233 can drive the second filter section 22 in the vertical direction (e.g., attached). Figure 1 When the cleaning device 100 is suctioning air, the telescopic support 233 can move the second filter section 22 to the first position, thereby sealing the gap between the upper part of the second filter section 22 and the main support, preventing unfiltered air and impurities from flowing directly out of the filter device 20 through the aforementioned gap, and optimizing the filtration performance of the filter device 20.

[0064] Combination Figures 1 to 5In some embodiments, the main support includes a first support portion 2311, wherein the upper end of the first filter portion 21 is clearance-fitted with the first support portion 2311. For example, the first support portion 2311 is provided with a sealing groove 2301 with its opening facing the first filter portion 21. The groove wall of the sealing groove 2301 can extend toward the first filter portion 21 in the vertical direction. The groove wall of the sealing groove 2301 can wrap around at least a portion of the upper end of the first filter portion 21, and there is a gap between the groove wall of the sealing groove 2301 and the outer wall of the first filter portion 21, so that the first filter portion 21 can rotate relative to the first support portion 2311. In addition, without affecting the rotation and filtration of the first filter portion 21, the gap between the groove wall and the upper end of the first filter portion 21 is as narrow and long as possible to prevent large impurities and dust from entering the gap between the first filter portion 21 and the sealing groove 2301 and affecting the rotation of the first filter portion 21.

[0065] Optionally, the gap between the groove wall of the sealing groove 2301 and the outer wall of the first filter part 21 can be in the range of 0.4mm to 3mm, with a preferred gap of 0.7mm. With this size gap, the first filter part 21 can deform and vibrate when rotating, thereby providing sufficient redundancy space for the offset of the upper position of the first filter part 21, avoiding interference between the first support part 2311 and the first filter part 21, and reducing the amount of garbage entering the gap when the first filter part 21 is stationary.

[0066] In some embodiments, the upper end of the second filter section 22 at the first position is sealed to the first support section 2311 to enhance the sealing between the second filter section 22 and the first support section 2311.

[0067] In conjunction with the foregoing embodiments, the second filter section 22 may include a mounting section 221. At least a portion of the upper end of the first filter section 21 and the upper end of the mounting section 221 extend into the sealing groove 2301. When the second filter section 22 is in the first position, the upper end of the mounting section 221 abuts against the top wall of the sealing groove 2301 and seals the gap between the upper end of the mounting section 221 and the sealing groove 2301, preventing unfiltered air from flowing directly out of the filter device 20 through the gap between the mounting section 221 and the sealing groove 2301, thereby improving the filtration effect of the filter device 20.

[0068] Optionally, the first support portion 2311 may be provided with a first sealing element 30. When the second filter portion 22 is in the first position, the mounting portion 221 of the second filter portion 22 may abut against the first sealing element 30 to seal the gap between the second filter portion 22 and the first support portion 2311, and at the same time reduce the friction between the second filter portion 22 and the first support portion 2311.

[0069] Combination Figure 1 , Figure 4 , Figure 10 and Figure 11 In some embodiments, the main support further includes a second support portion 2312, which is connected to the first support portion 2311 and is located below the first support portion 2311. A rotating support 232 is rotatably sleeved on the outside of the second support portion 2312, and a first filter portion 21 is connected to the rotating support 232, so that the first filter portion 21 is rotatable relative to the main support.

[0070] For example, the second filter section 22 may further include a mounting section 221, wherein a plurality of first connecting posts 2315 of the first support section 2311 extend from top to bottom into a plurality of third connecting posts 2211 of the mounting section 221, and a plurality of second connecting posts 2316 of the second support section 2312 extend from bottom to top into a plurality of third connecting posts 2211 of the mounting section 221, and the plurality of first connecting posts 2315 and the plurality of second connecting posts 2316 are connected to maintain the relative fixation of the first support section 2311 and the second support section 2312; the plurality of third connecting posts 2211 are slidable relative to the plurality of first connecting posts 2315 and the plurality of second connecting posts 2316, so that the second filter section 22 can move in the vertical direction relative to the main support.

[0071] The rotating support 232 includes a connecting part 2321 and a dust collection part 2322. The connecting part 2321 is snapped into the dust collection part 2322. A third snap 2326 may be provided on the inner side of the connecting part 2321, and a third latch 2327 may be provided on the upper end of the dust collection part 2322. When the connecting part 2321 is connected to the dust collection part 2322, the third snap 2326 can be engaged in the third latch 2327. The rotating support 232 may be located at the lower end of the second filter part 22. The lower end of the second filter part 22 is provided with a dust discharge port. The dust filtered by the second filter part 22 is discharged from the second filter part 22 through the dust discharge port, and the dust falls into and is stored in the dust collection part 2322.

[0072] In addition, combined Figure 4 , Figure 9 and Figure 11 The inner wall of the dust collection section 2322 is provided with a mounting groove 2328 for mounting the bearing 234. The dust collection section 2322 is rotatably connected to the second support section 2312 via the bearing 234. The mounting groove 2328 is provided with a limiting protrusion, and the second support section 2312 is provided with a limiting step 2318. When the dust collection section 2322 is mounted on the second support section 2312 via the bearing 234, the limiting protrusion and the limiting step 2318 can prevent the axial movement of the bearing 234, thereby preventing the axial movement of the first filter section 21 (e.g., attached). Figure 1The first filter unit 21 moves in the vertical direction. Furthermore, both the dust collection section 2322 and the second support section 2312 are interference-fitted with the bearing 234. This interference fit ensures that the dust collection section 2322 and the second support section 2312 are tightly fitted to the bearing 234, preventing loosening and vibration caused by gaps between the bearing 234 and the dust collection section 2322 and the second support section 2312, thereby improving the stability of the rotation of the first filter unit 21.

[0073] Optionally, combined Figure 10 The outer peripheral surface of the connecting part 2321 may be provided with multiple first blades 2323, which may extend in the vertical direction. The side wall of the dust cup 10 is provided with an air inlet 14. The air drawn in by the cleaning equipment 100 can enter the dust cup 10 through the air inlet 14. The air is continuously drawn into the dust cup 10 to form an airflow. The airflow can drive the multiple first blades 2323 to rotate the rotating support 232, thereby driving the first filter part 21 to rotate.

[0074] Optionally, combined Figure 11 The inner circumferential surface of the dust collection section 2322 may also be provided with a plurality of second blades 2324. The second blades 2324 may be configured to receive the rotational force generated by the air flow from the first filter section 21 and the second filter section 22. External air enters the dust cup 10 through the air inlet 14. After passing through the first filter section 21 and the second filter section 22, part of the air flow flows into the dust collection section 2322. The airflow moves toward the opening 13 of the dust cup 10 so as to discharge the dust stored in the dust collection section 2322.

[0075] Combination Figures 1 to 5 In some embodiments, the telescopic support 233 is movably inserted through the inner side of the second support portion 2312 in the vertical direction, so that the telescopic support 233 drives the second filter portion 22 to move in the vertical direction.

[0076] For example, the second filter section 22 includes a mounting section 221. The connecting column of the mounting section 221 is fixedly connected to the telescopic support 233 by bolts 2331. The telescopic support 233 can drive the second filter section 22 to move in the vertical direction. The interior of the second support section 2312 is provided with a sliding groove 2317. The telescopic support 233 can pass through the sliding groove 2317 and move in the vertical direction within the sliding groove 2317, ensuring that the telescopic support 233 drives the second filter section 22 to move in the vertical direction, so that the second filter section 22 can move to the first position to close the gap between the second filter section 22 and the first support section 2311.

[0077] In some embodiments, when the cup lid 11 opens the opening 13, the second filter section 22 moves down to a second position, and the gap between the upper end of the first filter section 21 and the upper end of the second filter section 22 is opened. Specifically, in the second position, the gap between the upper end of the second filter section 22 and the upper end of the first filter section 21 is open, allowing airflow to flow directly into the interior of the second filter section 22 through the gap, and expelling dust and other impurities from the first filter section 21 and the second filter section 22 from the opening 13 into the dust cup 10, thereby cleaning the dust cup 10 and the filter device 20.

[0078] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments, the upper end of the filter device 20 is provided with a limiting part 24. In the first position, the second filter part 22 stops against the limiting part 24 and restricts the rotation of the first filter part 21. When the cup lid 11 opens the opening 13, the second filter part 22 moves down to the second position, and the upper end of the second filter part 22 separates from the limiting part 24 to release the restriction on the rotation of the first filter part 21.

[0079] For example, the limiting part 24 can be provided at the upper end of the first filter part 21. The limiting part 24 has a first inclined surface that slopes upward toward the second filter part 22. The upper end of the second filter part 22 can also be provided with a second inclined surface that slopes upward toward the inner side of the second filter part 22. When the cup lid 11 closes the opening 13, the second filter part 22 moves upward to the first position, the second inclined surface moves upward and stops against the first inclined surface, restricting the rotation of the first filter part 21. At the same time, the gap between the upper end of the second filter part 22 and the upper end of the first filter part 21 is closed to prevent unfiltered air from being discharged from the filter device 20. When the cup lid 11 opens the opening 13, the second filter part 22 moves downward to the second position, the second inclined surface moves downward and away from the first inclined surface, and the first filter part 21 can rotate relative to the second filter part 22 to facilitate the cleaning of longer and more numerous impurities such as hair wrapped around the outside of the first filter part 21. Under the action of airflow, the impurities and dust in the dust cup 10 and the filter device 20 are discharged from the opening 13.

[0080] Optionally, in conjunction with the foregoing embodiments, the bracket 23 may include a first support portion 2311, a second support portion 2312, and a telescopic support 233. The first support portion 2311 is fixed relative to the dust cup 10, the second support portion 2312 is connected to the first support portion 2311, and the telescopic support 233 passes through the interior of the second support portion 2312 and can move in the vertical direction. The second filter portion 22 may also include a mounting portion 221 and a limiting plate 223. The connecting column of the mounting portion 221, the connecting column of the limiting plate 223, and the telescopic support 233 can be fixedly connected by bolts 2331. The telescopic support 233 can drive the second filter portion 22 to move in the vertical direction between a first position and a second position. When the second filter portion 22 moves down to the second position, the lower part of the limiting plate 223 abuts against the top of the second support portion 2312, restricting the second filter portion 22 from moving further down and preventing the second filter portion 22 from falling off.

[0081] Combination Figure 7 In some embodiments, the second filter section 22 is a multi-cone filter 222. The multi-cone filter 222, through the synergistic action of multiple cones, utilizes centrifugal force to separate airborne particles from the air, effectively capturing smaller particles and significantly improving the filtration efficiency. Furthermore, the multi-cone filter 222 also includes a HEPA filter assembly 25. Since the multi-cone filter 222 can separate the vast majority of dust, the HEPA filter assembly 25 hardly bears the primary filtration burden, preventing dust accumulation on it and thus reducing the frequency of replacement and cleaning, and extending its service life.

[0082] Optionally, combined Figure 7 and Figure 12 Sealing rings 26 can be provided between the mounting part 221 of the first support part 2311 and the second filter part 22, the mounting part 221 and the multi-cone filter 222, the multi-cone filter 222 and the limiting plate 223, the connecting part 2321 of the rotating support 232 and the dust collection part 2322, respectively. This can reduce dust accumulation at the connection between the components. At the same time, when the cup lid 11 closes the opening 13, the multiple sealing rings 26 can prevent dust in the dust collection part 2322 from re-entering the second filter part 22 and prevent unfiltered air from flowing directly out of the filter device 20 from the gap between the components, thereby improving the filtration efficiency of the filter device 20.

[0083] Combination Figure 1 , Figure 4 , Figure 13 and Figure 14According to an embodiment of the present invention, a cleaning system 1000 includes: a base station 200 having a docking interface 201; and the aforementioned cleaning device 100, which is detachably docked with the docking interface 201. When the lower end of the dust cup 10 docks with the docking interface 201, the docking interface 201 may have a negative pressure to drive the cup lid 11 to open the opening 13, and the docking interface 201 may unload the negative pressure to close the opening 13 of the cup lid 11.

[0084] For example, the cleaning device 100 may also include a suction device 110 for creating a negative pressure relative to the dust cup 10 within the base station 200. The suction device 110 may be located on the upper part of the dust cup 10. In conjunction with the above embodiments, the cleaning device 100 is connected to the base station 200, and when the suction device 110 is running, the suction device 110 and the dust cup 10 are not connected to each other. The air inside the base station 200 is drawn out to the outside by the suction device 110, and a negative pressure is formed inside the base station 200 relative to the dust cup 10. The pressure inside the dust cup 10 is greater than the pressure inside the base station 200. The air pressure inside the dust cup 10 acts on the cup lid 11, causing the cup lid 11 to open the opening 13. At this time, the telescopic support 233 loses the restraining force of the cup lid 11. The telescopic support 233 drives the second filter part 22 to move downward to the second position. The gap between the first filter part 21 and the second filter part 22 is opened, and the airflow can flow directly through the second filter part 22 and into the dust collection part 2322 of the rotating support 232, discharging the dust in the dust collection part 2322 from the opening 13 into the base station 200. The upper end of the second filter part 22 separates from the limiting part 24, and the first filter part 21 rotates under the action of the airflow.

[0085] Furthermore, the first filter section 21 can rotate when the cleaning device 100 is connected to the base station 200, allowing hair and other filaments wrapped around it to loosen and fall off more easily. This also makes it easier to clean dirt from the outer surface of the first filter section 21. This achieves cleaning of both the dust cup 10 and the first filter section 21, eliminating the need for an additional cleaning mechanism. The structure is simpler and less expensive, and it prevents the first filter section 21 from clogging, allowing the cleaning device 100 to maintain a consistently good cleaning effect. When the suction device 110 stops operating, the negative pressure inside the base station 200 disappears, and the cup lid 11 closes the opening 13.

[0086] In conjunction with the foregoing, after the cup lid 11 closes the opening 13, the cup lid 11 abuts against the bottom of the telescopic support 233, and drives the telescopic support 233 to move the second filter part 22 to the first position. The upper end of the second filter part 22 is sealed with the first support part 2311 to prevent unfiltered air and impurities from flowing directly out of the filter device 20 through the gap between the second filter part 22 and the first support part 2311, thereby optimizing the filtration performance of the filter device 20. The upper end of the second filter part 22 abuts against the limiting part 24 to restrict the rotation of the first filter part 21. When the cleaning device 100 is detached from the base station 200 and sucks up impurities and air from the external environment, the dust cup 10 is connected to the suction device 110. The side wall of the dust cup 10 is provided with an air inlet 14. The sucked air and impurities flow into the dust cup 10 through the air inlet 14. After being filtered by the first filter part 21 and the second filter part 22, the air in the dust cup 10 flows out from the top of the dust cup 10 into the suction device 110.

[0087] Furthermore, in the first position, the upper end of the second filter section 22 is sealed to the first support section 2311, which can prevent unfiltered air from flowing directly into the suction device 110 from the gap between the upper part of the second filter section 22 and the first support section 2311, and prevent dust and other impurities from accumulating in the suction device 110, thereby ensuring the normal operation of the suction device 110 and extending the service life of the suction device 110.

[0088] Optionally, the suction device 110 can be installed in the cleaning equipment 100. The suction device 110 can be used to suction impurities and air from the external environment. When the cleaning equipment 100 is connected to the base station 200, the suction device 110 can be used to suction air from inside the base station 200, creating a negative pressure inside the base station 200 relative to the dust cup 10, and driving the cup cover 11 to open the opening 13. Setting a single suction device 110 can reduce the number of components in the cleaning system 1000 and reduce the production cost of the cleaning system 1000. Of course, an additional suction motor can also be installed inside the base station 200 to create a negative pressure inside the base station 200 relative to the dust cup 10 and drive the cup cover 11 to open the opening 13.

[0089] The specific structure of the cleaning device 100 is as described in the above embodiments. Since the cleaning device 100 adopts the technical solution of the above embodiments, it has at least the beneficial effects brought about by the technical solution of the above embodiments, which will not be described in detail here.

[0090] Combination Figure 1 and Figure 13The cleaning device 100 according to an embodiment of the present invention includes a main unit 40 and a filter device 20. The main unit 40 includes a cup lid 11; the filter device 20 is connected to the main unit 40 and is used to filter air and impurities drawn into the main unit 40; the filter device 20 includes a rotatable first filter section 21 and at least a portion of a second filter section 22 disposed within the first filter section 21. The second filter section 22 can move up and down relative to the first filter section 21 along the axis of the first filter section 21. When the cup lid 11 is closed, the second filter section 22 moves upward to a first position, and the gap between the upper end of the second filter section 22 and the upper end of the first filter section 21 is sealed, preventing air from flowing directly out of the main unit 40 through the gap between the first filter section 21 and the second filter section 22, thereby improving the filtration effect of the filter device 20.

[0091] Furthermore, the first filter section 21 is rotatable relative to the second filter section 22, so as to loosen the hair and other filaments wrapped around the first filter section 21. The filaments are easier to fall off, and the dirt on the outer surface of the first filter section 21 is easier to clean. This achieves cleaning of the inside of the main unit 40 and the first filter section 21 without the need for an additional cleaning mechanism for cleaning the first filter section 21. The structure is simpler and the cost is lower. Moreover, it makes the first filter section 21 less prone to clogging, and the cleaning device 100 can maintain a good cleaning effect continuously.

[0092] According to the cleaning device 100 of this utility model embodiment, by sealing the gap between the upper end of the second filter section 22 and the upper end of the first filter section 21, the overall structure of the filter device 20 is simple, while enhancing the sealing between the first filter section 21 and the second filter section 22, ensuring that dirty air flows to the second filter section 22 after passing through the first filter section 21, and preventing dirty air from flowing directly out of the main unit 40 through the gap between the first filter section 21 and the second filter section 22, thereby improving the filtration efficiency of the filter device 20; at the same time, the first filter section 21 can be rotated to facilitate cleaning of hair and other filamentous materials wrapped around the outer surface of the first filter section 21, thereby achieving cleaning of the inside of the main unit 40 and the first filter section 21.

[0093] In conjunction with the foregoing, the axis of the first filter section 21 is along the vertical direction (see Appendix). Figure 1 Extending in the direction of the first filter section 21, the second filter section 22 can move relative to the first filter section 21 in the vertical direction so as to move up to the first position and close the gap between the upper end of the first filter section 21 and the upper end of the second filter section 22.

[0094] Combination Figure 13 In some embodiments, the filter device 20 is detachably connected to the main unit 40, which facilitates the removal and installation of the filter device 20.

[0095] For example, the filter device 20 may include a bracket 23, the first filter part 21 and the second filter part 22 may be disposed on the bracket 23, the main unit 40 may include a bottom cover (not shown in the figure), the upper end of the bracket 23 may be detachably snapped to the bottom cover of the main unit 40, the periphery of the upper end of the bracket 23 may be provided with a groove 2314, and the inner periphery of the bottom cover may be provided with a fourth snap (not shown in the figure). When the bracket 23 is connected to the bottom cover, the fourth snap can be disengaged and snapped into the groove 2314.

[0096] Among them, combined Figure 8 The main unit 40 may also include a dust cup 10 and a main body. The filter device 20 may be located at least partly inside the dust cup 10. The outer peripheral surface of the upper end of the bracket 23 may be provided with a first buckle 2313. The inner side wall of the dust cup 10 may be provided with a corresponding first slot 12. When the filter device 20 is connected to the dust cup 10, the first buckle 2313 can be disengaged and locked into the first slot 12. The dust cup 10 and the main body are detachably connected. When the user needs to disassemble the filter device 20, he / she can first separate the dust cup 10 from the main body by rotating and moving it, and then rotate the filter device 20 to make the fourth buckle exit the slot 2314, thereby separating the filter device 20 from the main unit 40 and thus realizing the disassembly of the filter device 20.

[0097] The cleaning device 100 and cleaning system 1000 of the present invention are described below with reference to the accompanying drawings.

[0098] According to embodiments of the present invention, a cleaning device 100 and a cleaning system 1000 are provided. The cleaning device 100 includes a dust cup 10, a cup lid 11, and a filter device 20. The cup lid 11 is located at an opening 13 at the bottom of the dust cup 10. The filter device 20 is located inside the dust cup 10 and includes a support 23, a first filter section 21, and a second filter section 22. The first filter section 21 and the second filter section 22 are located on the support 23. The first filter section 21 is rotatable relative to the second filter section 22, and the second filter section 22 is movable vertically between a first position and a second position. The cleaning system 1000 includes the aforementioned cleaning device 100 and a base station 200. The cleaning device 100 is detachably connected to the base station 200.

[0099] In the first position, the upper end of the second filter section 22 is sealed to the bracket 23, preventing airflow from passing through the aforementioned gap and avoiding unfiltered air from flowing out of the filter device 20 through the gap between the upper end of the second filter section 22 and the bracket 23, thereby improving the filtration effect of the filter device 20. At the same time, the second filter section 22 abuts against the limiting part 24, restricting the rotation of the first filter section 21. In the second position, airflow can pass through the gap between the upper end of the second filter section 22 and the bracket 23, the second filter section 22 is away from the limiting part 24, and the first filter section 21 can rotate relative to the second filter section 22 to facilitate cleaning of the dust cup 10 and the filter device 20.

[0100] In addition, the cleaning device 100 also includes a suction device 110, which can be located on the upper part of the dust cup 10. When the cleaning device 100 is detached from the base station 200, the suction device 110 is used to suck up impurities and air from the external environment. When the cleaning device 100 is docked with the base station 200, the suction device 110 is used to suck up the air inside the base station 200, so that a negative pressure is generated inside the base station 200 relative to the dust cup 10, and drives the cup cover 11 to open the opening 13. Setting up a single suction device 110 reduces the number of components in the cleaning system 1000 and reduces the production cost of the cleaning system 1000.

[0101] Combination Figure 4 and Figure 5 When the cleaning device 100 is connected to the base station 200 and the suction device 110 is running, the suction device 110 and the dust cup 10 are not connected. The air inside the base station 200 is drawn out to the outside by the suction device 110, and a negative pressure is formed inside the base station 200 relative to the dust cup 10. The pressure inside the dust cup 10 is greater than the pressure inside the base station 200. The air pressure inside the dust cup 10 acts on the cup cover 11, causing the cup cover 11 to open the opening 13. At this time, the telescopic support 233 loses the restraining force of the cup cover 11. The telescopic support 233 drives the second filter part 22 to move downward to the second position. The gap between the first filter part 21 and the second filter part 22 is opened, and the airflow can flow directly through the second filter part 22 and into the dust collection part 2322 of the rotating support 232, discharging the dust in the dust collection part 2322 from the opening 13 into the base station 200. The upper end of the second filter part 22 separates from the limiting part 24, and the first filter part 21 rotates under the action of the airflow.

[0102] Furthermore, the first filter section 21 can rotate when the cleaning device 100 is connected to the base station 200, allowing hair and other filaments wrapped around it to loosen and fall off more easily. This also makes it easier to clean dirt from the outer surface of the first filter section 21. This achieves cleaning of both the dust cup 10 and the first filter section 21, eliminating the need for an additional cleaning mechanism. The structure is simpler and less expensive, and it prevents the first filter section 21 from clogging, allowing the cleaning device 100 to maintain a consistently good cleaning effect. When the suction device 110 stops operating, the negative pressure inside the base station 200 disappears, and the cup lid 11 closes the opening 13.

[0103] Combination Figures 1 to 3After the cup lid 11 closes the opening 13, the cup lid 11 abuts against the bottom of the telescopic support 233 and drives the telescopic support 233 to move the second filter part 22 to the first position. The upper end of the second filter part 22 is sealed with the first support part 2311 to prevent unfiltered air and impurities from flowing directly out of the filter device 20 through the gap between the second filter part 22 and the first support part 2311, thereby optimizing the filtration performance of the filter device 20. The upper end of the second filter part 22 abuts against the limiting part 24 to restrict the rotation of the first filter part 21. When the cleaning device 100 is detached from the base station 200 and sucks up impurities and air from the external environment, the dust cup 10 is connected to the suction device 110. The side wall of the dust cup 10 is provided with an air inlet 14. The sucked air and impurities flow into the dust cup 10 through the air inlet 14. After the air in the dust cup 10 is filtered by the first filter part 21 and the second filter part 22, it flows out from the top of the dust cup 10 into the suction device 110.

[0104] Furthermore, in the first position, the upper end of the second filter section 22 is sealed to the first support section 2311, which can prevent unfiltered air from flowing out of the filter device 20 through the gap between the upper part of the second filter section 22 and the first support section 2311 and directly flowing into the suction device 110, thereby optimizing the filtration performance of the filter device 20 and preventing dust and other impurities from accumulating in the suction device 110, thus ensuring the normal operation of the suction device 110 and extending its service life.
