[0002] This application claims the priority of a Chinese patent application with the application number 202510363243.X, titled "Cleaning Equipment, Base Station and Cleaning System", filed with the Chinese Patent Office on March 25, 2025. The entire content of which is incorporated herein by reference. Technical field

[0003] The present invention relates to the technical field of cleaning tools, and particularly to a cleaning equipment and a cleaning system. Background art

[0004] Cleaning equipment generally includes a filter, a suction head, a suction device, a dust cup, etc. The external dirt is sucked in through the suction head and introduced into the dust cup, and is filtered by the filter, so that the dirt can be retained in the dust cup, while the filtered clean air can flow out of the filter and enter the suction device and be discharged from the cleaning equipment, forming an air flow cycle for the cleaning equipment to clean.

[0005] When the cleaning equipment is cleaning, the dirty air sucked in by the suction head enters the dust cup through the air inlet on the dust cup and rotates around the cylindrical filter. When the cleaning equipment sucks in some long hairs, due to the principle of the cyclone separator, the air flow drives the hairs to rotate around the filter. After long - term use, the long hairs will be wound around the surface of the filter, causing the filter to be blocked and affecting the suction and filtration efficiency. Summary of the invention

Detailed implementation manners

[0047] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where 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 drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0048] When the cleaning device is cleaning, the dirty air sucked in by the suction head enters the dust cup through the air inlet on the dust cup and rotates around the filter. When the cleaning device sucks in some long hairs, based on the principle of the cyclone separator, the airflow drives the hairs to rotate around the filter. After long-term use, the long hairs will wind around the surface of the filter, causing the filter to be blocked and affecting the efficiency of dust suction and filtration. In order to remove the hairs wound around the surface of the cyclone separator, it is necessary to additionally set up a cleaning mechanism, which results in a complex overall structure, increases the weight of the whole machine, affects the user experience, and at the same time, the cleaning mechanism needs to extend from the main machine into the dust cup, which may cause problems in sealing, and the complex structure is prone to failure and also increases the cost. Based on this, the present invention proposes a cleaning device, which can facilitate the cleaning of the dirt wound around the surface of the filtering device by improving the structure of the filtering device.

[0049] Combined with Figure 1 and Figure 3, the cleaning device 100 according to an embodiment of the present invention includes: a dust cup 10, the dust cup 10 includes a cup body 11 and a cup lid 12, the cup body 11 has an ash discharge port 111, and the cup lid 12 is used to open and close the ash discharge port 111. Specifically, a dust storage cavity may be provided in the dust cup 10. During the operation of the cleaning device 100, the cup lid 12 closes the ash discharge port 111, and dust, dirt, etc. are collected in the dust storage cavity. When it is necessary to clean the dust cup 10, the cup lid 12 opens the ash discharge port 111 to clean the dirt in the dust storage cavity. Exemplarily, the user can manually open the cup lid 12 to clean the dust cup 10, or the cleaning device 100 can be docked with the base station 200 to clean the dirt in the dust cup 10 through the base station 200.

[0050] Combined with Figure 1 , the cleaning device 100 further includes a filtering device 20, and at least a part of the filtering device 20 is disposed in the dust cup 10. Exemplarily, when the user uses the cleaning device 100 to clean the working surface, the cleaning device 100 is in the working state, and the filtering device 20 can be used to separate and filter the dirty air entering the dust storage cavity. The clean air flow after being filtered by the filtering device 20 flows through the air outlet of the dust cup 10 to the suction device of the cleaning device 100, and the filtered dust and impurities are collected in the dust storage cavity.

[0051] Combined with Figure 1 and Figure 3 , wherein at least a part of the filtering device 20 is disposed in the dust cup 10, the filtering device 20 includes a rotatable first filtering part 21 and a second filtering part 22, the second filtering part 22 is located downstream of the first filtering part, the second filtering part 22 has a first position and a second position. When the cup lid 12 closes the ash discharge port 111, the second filtering part 22 is in the first position and locks the first filtering part 21; when the cup lid 12 opens the ash discharge port 111, the second filtering part 22 is in the second position and releases the lock on the first filtering part 21, and the first filtering part 21 can rotate. Herein, "downstream" refers to the rear end position along the air flow direction, that is, in the path where the air flow flows from the upstream (starting point) to the downstream (ending point), the position passed later is the downstream.

[0052] Specifically, the second filtering part 22 is located downstream of the first filtering part 21. After the dust-containing air flow enters the dust cup, it is first filtered by the first filtering part 21 and then by the second filtering part 22. The first filtering part 21 can filter larger dust particles such as debris, hair and other dirt, and the second filtering part 22 can filter smaller dust particles and the like. Exemplarily, the dust cup 10 may have an air inlet 112. The air flow containing dirt and dust enters the dust storage cavity from the air inlet 112. The filtering device 20 filters the air flow. Larger dirt such as debris and hair is first filtered by the first filtering part 21 and intercepted outside the first filtering part 21. The second filtering part 22 filters the air flow filtered by the first filtering part 21 again. The filtered clean air flow flows through the air outlet of the dust cup 10 to the suction device of the cleaning device 100, and dirt such as dust is collected in the dust storage cavity. Combined with Figure 1 , when the cup cover 12 closes the ash discharge port 111, the cleaning device 100 can be in a working state. The second filtering part 22 is in the first position and locks the first filtering part 21. At this time, the first filtering part 21 cannot rotate. The cooperation of the first filtering part 21 and the second filtering part 22 can perform two-stage filtering on the dirty air entering the dust storage cavity, improving the working stability and cleaning effect of the cleaning device 100. Combined with Figure 2 , when the cup cover 12 opens the ash discharge port 111, the second filtering part 22 moves to the second position. At this time, the second filtering part 22 releases the lock on the first filtering part 21, and the first filtering part 21 can rotate around the axis. It can be understood that when the cleaning device 100 is in a working state and the dust-containing air flow enters the dust cup 10, a high-speed rotating air flow is formed in the dust cup 10. Filamentous substances such as hair are easily wound around the outside of the first filtering part 21, and it is easy to cause the first filtering part 21 to be blocked after long-term use. When the cup cover 12 opens the ash discharge port 111, the rotation of the first filtering part 21 around the axis can loosen the filamentous substances such as hair wound on the surface of the first filtering part 21, facilitating the separation of the filamentous substances such as hair from the first filtering part 21. There is no need to additionally set a cleaning mechanism for cleaning the first filtering part 21, and the filtering device 20 is not easy to be blocked, so that the cleaning device 100 can still maintain a good cleaning effect after long-term use.

[0053] Exemplarily, the first filtering part 21 may include a filter screen or sponge, etc., to perform primary filtering on the dirt entering the dust cup 10. The second filtering part 22 may include a HEPA filter or a cyclone separator, etc. The second filtering part 22 is located downstream of the first filtering part 21 and can filter the air flow filtered by the first filtering part 21 again.

[0054] Among them, when the cup cover 12 opens the dust discharge port 111, the second filtering part 22 releases the locking of the first filtering part 21. The first filtering part 21 can rotate around the axis, and the first filtering part 21 can be driven to rotate by an external force. Exemplarily, the cleaning device 100 can be docked with the base station 200, and the dirt in the dust cup 10 can be cleaned by the base station 200, reducing the operation burden of the user. The first filtering part 21 can be directly driven to rotate by a driving structure such as a motor provided on the cleaning device 100 or the base station 200; or, the first filtering part 21 can be driven to rotate by the airflow introduced into the cup body 11 from the air inlet 112 of the dust cup 10, etc.

[0055] In addition, the second filtering part 22 has a first position and a second position. Among them, the second filtering part 22 can move between the first position and the second position along the axis direction of the first filtering part 21, that is to say, the first position and the second position are distributed in the up and down direction; or, the second filtering part 22 can move between the first position and the second position around the axis of the first filtering part 21.

[0056] For the cleaning device 100 according to an embodiment of the present invention, the second filtering part 22 has a first position and a second position. When in the first position, the first filtering part 21 is locked, which is convenient for the first filtering part 21 and the second filtering part 22 to cooperate to filter the dirt entering the dust cup 10. When the cup cover 12 opens the dust discharge port 111, the second filtering part 22 is in the second position, and the second filtering part 22 releases the locking of the first filtering part 21. The first filtering part 21 can rotate, which can loosen the filaments wound on the surface of the first filtering part 21, facilitating the separation of the filaments from the first filtering part 21 and avoiding the blockage of the filtering device 20 by the filaments.

[0057] Among them, at least a part of the filtering device 20 is provided in the dust cup 10. Exemplarily, all of the filtering device 20 can be provided in the dust cup 10; or, a part of the filtering device 20 is provided in the dust cup 10. Among them, the filtering device 20 can be connected to the dust cup 10, that is to say, when the dust cup 10 is separated from the main body of the cleaning device 100, the filtering device 20 can be separated from the main body of the cleaning device 100 together with the dust cup 10; or, the filtering device 20 can be connected to the main body of the cleaning device 100, and the dust cup 10 is detachably connected to the main body of the cleaning device 100. After the dust cup 10 is installed on the main body of the cleaning device 100, at least a part of the filtering device 20 extends into the dust cup 10, so as to facilitate the filtering device 20 to filter the dust and dirt sucked into the dust cup 10. When the dust cup 10 is separated from the main body of the cleaning device 100, the filtering device 20 is still connected to the main body of the cleaning device 100. When the dust cup 10 needs to be replaced or cleaned, the disassembly of the dust cup 10 is more convenient. Since the filtering device 20 is connected to the main body of the cleaning device 100, the disassembly and assembly of the dust cup 10 do not affect the filtering device 20, improving the disassembly and assembly efficiency of the dust cup 10.

[0058] In some embodiments of the present invention, the second filtering part 22 is configured to move up and down along the axial direction of the first filtering part 21 relative to the first filtering part 21 to switch between a first position and a second position. Specifically, in combination with Figure 1 , the axis of the first filtering part 21 is A. The first position can be located above the second position. When the cup cover 12 opens the ash discharge port 111, the second filtering part 22 can move downward to the second position and release the locking of the first filtering part 21. When the cup cover 12 closes the ash discharge port 111, the second filtering part 22 moves upward to the first position to lock the first filtering part 21. The second filtering part 22 moves up and down along the axial direction of the first filtering part 21, which facilitates the locking and releasing of the first filtering part 21 by the second filtering part 22.

[0059] Optionally, the filtering device 20 may include a support structure. The second filtering part 22 may be fixedly connected to the support structure, and the first filtering part 21 is rotatably connected to the support structure; or, the second filtering part 22 is fixedly connected to the support structure, and the first filtering part 21 is rotatably connected to the second filtering part 22.

[0060] In the present invention, the cleaning device 100 can be a vacuum cleaner, a floor sweeping robot, a mite remover, a floor washer, etc.

[0061] In some embodiments of the present invention, at least a part of the second filtering part 22 is disposed inside the first filtering part 21, making the structure of the filtering device 20 more compact. Specifically, all of the second filtering part 22 may be disposed inside the first filtering part 21, or a part of the second filtering part 22 is disposed inside the first filtering part 21, and the other part extends out of the first filtering part 21.

[0062] In some embodiments of the present invention, the second filtering part 22 abuts against the first filtering part 21 at the first position and restricts the rotation of the first filtering part 21. By directly contacting the first filtering part 21 and the second filtering part 22, the rotation of the first filtering part 21 is restricted, simplifying the structure of the filtering device 20. Specifically, when the cup cover 12 closes the ash discharge port 111, the second filtering part 22 is at the first position. The second filtering part 22 contacts the first filtering part 21 and applies a force to the first filtering part 21 to restrict the rotation of the first filtering part 21, facilitating the filtering of the dirt entering the dust cup 10 through the cooperation of the first filtering part 21 and the second filtering part 22, and improving the working stability of the cleaning device 100.

[0063] In combination with Figure 1 and Figure 2, wherein, the upper end of the first filter part 21 has a first fitting 211, and the upper end of the second filter part 22 has a second fitting 221. In the first position, the first fitting 211 and the second fitting 221 are in contact, and provide damping for the rotation of the first filter part 21. Specifically, when the second filter part 22 is in the first position, the first fitting 211 and the second fitting 221 are in contact, preventing the first filter part 21 from rotating. When the second filter part 22 moves to the second position, the position of the first filter part 21 in the axial direction is relatively fixed. Therefore, the first fitting 211 and the second fitting 221 are separated. At this time, the second filter part 22 releases the locking of the first filter part 21. By arranging the first fitting 211 at the upper end of the first filter part 21 and the second fitting 221 at the upper end of the second filter part 22, it is convenient for the second filter part 22 to contact the first filter part 21 and limit the rotation of the first filter part 21 when in the first position. When the second filter part 22 moves downward, the second filter part 22 can quickly release the locking of the first filter part 21, simplifying the structure of the filtering device 20.

[0064] Combined with Figure 4 , in some embodiments of the present invention, the first filter part 21 includes a filter net 2121 and a filter net support 2122. The filter net support 2122 surrounds the axis of the first filter part 21 and has a hollow structure. The filter net 2121 is arranged on the filter net support 2122 to cover the hollow structure, and the first fitting 211 is arranged at the upper end of the filter net support 2122. The filter net support 2122 can support and fix the filter net 2121, improving the structural strength and stability of the first filter part 21. By arranging the first fitting 211 at the upper end of the filter net support 2122, the filter net support 2122 can be directly used to cooperate with the second filter part 22, without additionally setting complex cooperation structures between the first filter part 21 and the second filter part 22, simplifying the structure of the filtering device 20.

[0065] Combined with Figure 4 , in some embodiments of the present invention, the second filter part 22 includes a multi - cone body 222 and an upper cover plate 223. The upper cover plate 223 is connected to the upper end of the multi - cone body 222 and includes a wind guide column 2231 communicating with the multi - cone body 222. Specifically, the second filter part 22 can be a multi - cone filtering structure. When the cleaning device 100 is in a working state, the dirty air entering the dust storage cavity of the cup body 11 passes through the first filter part 21, enters the interior of the first filter part 21, and then flows into the multi - cone body 222 for further filtration. The airflow that has completed filtration in the multi - cone body 222 flows through the wind guide column 2231 on the upper cover plate 223 to the suction device. Among them, the second fitting 221 can be arranged on the upper cover plate 223, and the upper cover plate 223 can be directly used to cooperate with the first filter part 21, without additionally setting complex cooperation structures between the first filter part 21 and the second filter part 22, simplifying the structure of the filtering device 20.

[0066] Combination Figure 1 , optionally, the second filter part 22 may further include a lower cover plate 224, and the lower cover plate 224 is connected to the lower end of the multi-cone body 222. In the first position, the lower cover plate 224 abuts against the first filter part 21. The lower cover plate 224 can provide a certain damping for the rotation of the first filter part 21. That is to say, in the first position, both the upper end and the lower end of the second filter part 22 are in contact with the first filter part 21 to effectively limit the rotation of the first filter part 21, so that the first filter part 21 and the second filter part 22 cooperate to filter the air flow entering the dust cup 10.

[0067] Exemplarily, the lower cover plate 224 may be provided with a rubber member. When in the first position, the rubber member abuts against the first filter part 21. On the one hand, it can seal the space between the first filter part 21 and the second filter part 22. On the other hand, it can provide damping for the rotation of the first filter part 21 through the rubber member.

[0068] Combination Figure 2 and Figure 4 , in some embodiments of the present invention, the inner peripheral surface of the first fitting 211 includes a first tapered surface 2111 that tapers in the upward direction, and the outer peripheral surface of the second fitting 221 includes a second tapered surface 2211 that tapers in the upward direction. In the first position, the second tapered surface 2211 abuts against the first tapered surface 2111. In the first position, the cooperation between the first tapered surface 2111 and the second tapered surface 2211 can stably limit the rotation of the first filter part 21, which is convenient for the first filter part 21 and the second filter part 22 to cooperate to filter the air flow entering the dust cup 10. When the second filter part 22 moves from the first position to the second position, the design of the first tapered surface 2111 and the second tapered surface 2211 can facilitate the separation of the first filter part 21 and the second filter part 22, avoiding the first filter part 21 from hindering the movement of the second filter part 22. In addition, when the second filter part 22 moves from the second position to the first position, the tapered surface can play a guiding role, thereby improving the smoothness of the second filter part 22 during the switching between the first position and the second position.

The support part 23 can support the rotation of the first filter part 21, improve the stability of the first filter part 21 during rotation, and further facilitate the loosening of the filaments wound on the surface of the first filter part 21. At the same time, the support part 23 can support the second filter part 22 to slide along the axis direction, improve the stability of the second filter part 22 during movement along the axis direction, and further facilitate the second filter part 22 to stably lock and release the first filter part 21.

In the second position, the lower cover plate 224 abuts against the lower bracket 232. The cooperation between the lower cover plate 224 and the lower bracket 232 can limit the second filter part 22 to prevent the second filter part 22 from disengaging from the second position.

When the cup cover 12 closes the ash discharge port 111, the lower end of the push rod 24 abuts against the cup cover 12. Specifically, the upper end of the push rod 24 is fixedly connected to the second filter part 22 through the upper cover plate 223 and the lower cover plate 224, and the lower end passes through the support part 23 and abuts against the cup cover 12 when the cup cover 12 is in a closed state. When the cup cover 12 is in a position to close the ash discharge port 111 of the cup body 11, the cup cover 12 presses against the push rod 24. Under the action of the pushing force of the cup cover 12, the push rod 24 makes the second filter part 22 in the first position, thereby locking the first filter part 21. At this time, the first filter part 21 is in a locked state; when the cup cover 12 is in a position to open the ash discharge port 111, the push rod 24 is no longer pushed by the cup cover 12. At this time, the second filter part 22 can slide to the second position under the action of gravity, thereby unlocking the first filter part 21.

By providing the support portion 23 to cooperate with the rotating support member 213, the first filter portion 21 is stably supported to rotate, thereby improving the stability of the first filter portion 21 during the rotation process.

[0086] Combination Figure 3, Further, the rotary support member 213 includes a support body 2131. The support body 2131 is connected to the lower end of the filter screen body 212 and extends in the direction of the ash discharge port 111. A secondary dust accumulation cavity 2133 communicating with the second filtering part 22 is defined inside the support body 2131. At least a part of the inner peripheral surface of the support body 2131 is a tapered surface that tapers in the top-down direction. Specifically, a secondary dust accumulation cavity 2133 for accommodating the dust filtered by the second filtering part 22 is formed inside the support body 2131. The dust filtered by the second filtering part 22 falls into the secondary dust accumulation cavity 2133 from the opening at the upper end of the rotary support member 213. When the cup cover 12 closes the ash discharge port 111, the opening at the lower end of the rotary support member 213 can be sealed by the cup cover 12. When the cup cover 12 opens the ash discharge port 111, the dust in the secondary dust cavity can be discharged from the ash discharge port 111. Among them, at least a part of the inner peripheral surface of the support body 2131 is a tapered surface that tapers in the top-down direction, which can guide the dust in the secondary dust accumulation cavity 2133, facilitating the rapid discharge of the dust in the secondary dust accumulation cavity 2133 after the cup cover 12 opens the ash discharge port 111.

[0087] Combined with Figure 6 and Figure 7 , Further, the rotary support member 213 further includes a positioning portion 2132. The positioning portion 2132 is provided inside the lower end of the support body 2131. There is a channel 2134 extending in the up-down direction between the support body 2131 and the positioning portion 2132. The positioning portion 2132 is rotatably sleeved on the outside of the support portion 23. Specifically, the channel 2134 between the positioning portion 2132 and the support body 2131 can facilitate the discharge of the dust in the secondary dust accumulation cavity 2133. The positioning portion 2132 is provided inside the support body 2131, which can make full use of the space inside the support body 2131, cooperate with the support portion 23, support the rotation of the first filtering part 21, and make the structure of the filtering device 20 compact and improve the space utilization rate.

[0088] Exemplarily, ribs may be connected between the support body 2131 and the positioning portion 2132, which can strengthen the connection stability between the support body 2131 and the positioning portion 2132 and facilitate the definition of the channel 2134 between the support body 2131 and the positioning portion 2132, facilitating the discharge of the dust in the secondary dust accumulation cavity 2133 from the ash discharge port 111.

[0089] Combined with Figure 3 , In some embodiments of the present invention, a bearing 214 is provided between the positioning portion 2132 and the support portion 23 to reduce the friction when the rotary support member 213 rotates relative to the support portion 23, improve the rotation smoothness of the first filtering part 21, and further facilitate the loosening of the filaments wound on the surface of the first filtering part 21.

[0090] In some embodiments of the present invention, combined withFigure 6 and Figure 7 In the figure, the bearing 214 is hidden. The positioning portion 2132 is provided with a first positioning groove 21321. The outer ring of the bearing 214 is arranged in the first positioning groove 21321. The first positioning groove 21321 can position the bearing 214 to prevent the bearing 214 from axially displacing relative to the rotating support member 213.

[0091] In some embodiments of the present invention, in combination with Figure 6 and Figure 7 In the figure, the bearing 214 is hidden. The lower end of the support portion 23 is provided with a second positioning groove 2323. The inner ring of the bearing 214 is arranged in the second positioning groove 2323. The second positioning groove 2323 can position the bearing 214 to prevent the bearing 214 from axially displacing relative to the support portion 23.

[0092] In some embodiments of the present invention, the positioning portion 2132 is provided with a first positioning groove 21321, and the lower end of the support portion 23 is provided with a second positioning groove 2323. The outer ring of the bearing 214 is arranged in the first positioning groove 21321, and the inner ring of the bearing 214 is arranged in the second positioning groove 2323.

The positioning portion 2132 is provided with a first positioning groove 21321, and the support portion 23 is provided with a second positioning groove 2323. When the rotating support member 213 is installed on the support portion 23 through the bearing 214, the cooperation of the first positioning groove 21321 and the second positioning groove 2323 can prevent the axial movement of the bearing 214, thereby avoiding the axial movement of the first filtering portion 21 and improving the structural stability of the first filtering portion 21.

[0093] In combination with Figure 5 wherein, the support portion 23 may include an upper bracket 231 and a lower bracket 232. The first filtering portion 21 may be rotatably connected to the support shaft 2322. The upper bracket 231 and the lower bracket 232 are fixedly connected. The second filtering portion 22 is clamped between the upper bracket 231 and the lower bracket 232. A sliding interval for the second filtering portion 22 may be defined between the upper bracket 231 and the lower bracket 232. The upper bracket 231 and the lower bracket 232 may be fixedly connected by at least one set of connecting columns arranged therebetween. The second filtering portion 22 includes a sliding groove 225 or a sliding hole for slidingly cooperating with the connecting columns. Wherein, a support shaft 2322 may be provided on a side of the lower bracket 232 facing away from the second filtering portion 22. The rotating support member 213 may be rotatably connected to the support shaft 2322. That is to say, the upper bracket 231 and the lower bracket 232 define a sliding interval for the second filtering portion 22 for supporting the second filtering portion 22 to slide in the up and down direction. The lower end of the lower bracket 232 is provided with a support shaft 2322, and the support shaft 2322 is rotatably connected to the first filtering portion 21, which can support the rotation of the first filtering portion 21 and improve the structural stability of the first filtering portion 21.

[0094] In some embodiments of the present invention, the cleaning device 100 has a working mode and a self-cleaning mode. In the working mode, the second filtering part 22 is in the first position. In the self-cleaning mode, the second filtering part 22 is in the second position. Specifically, when the cleaning device 100 is in the working mode, it can be used to clean the working surface. The second filtering part 22 is in the first position, and the second filtering part 22 locks the first filtering part 21, and the first filtering part 21 cannot rotate. The first filtering part 21 and the second filtering part 22 cooperate to filter the airflow entering the dust cup 10, improving the cleaning effect of the cleaning device 100. When the cleaning device 100 is in the self-cleaning mode, the cleaning device 100 can cooperate with the base station 200 to discharge dust, dirt, etc. inside the cleaning device 100, realizing self-cleaning of the cleaning device 100. The second filtering part 22 is in the second position, and the first filtering part 21 can rotate around the axis, facilitating the loosening of the filaments wound on the surface of the first filtering part 21 during the self-cleaning mode, so that the dirt on the outer surface of the first filtering part 21 is more easily cleaned.

[0095] Combined with Figures 8 to 10 , the cleaning system 1000 according to the first aspect embodiment of the present invention includes: a base station 200 and the aforementioned cleaning device 100, and the base station 200 has a docking interface 210. Among them, the dust cup 10 is separable and dockable with the docking interface 210. Exemplarily, when the cleaning device 100 is in the working mode, the cup cover 12 closes the dust discharge port 111. In the self-cleaning mode, the cup cover 12 opens the dust discharge port 111, and the dust discharge port 111 communicates with the base station 200 to facilitate cleaning the dirt in the dust cup 10 through the base station 200.

[0096] Exemplarily, an unlocking member may be provided on the base station 200. After the cleaning device 100 is docked with the base station 200, the unlocking member can trigger the opening of the dust discharge port 111 of the dust cup 10, that is, the dust discharge port 111 can be opened through a mechanical structure; or, when the cleaning device 100 is in the self-cleaning mode, under the action of the suction device, a negative pressure is generated in the base station 200, and the dust discharge port 111 is opened under the action of the negative pressure.

[0097] In some embodiments of the present invention, the docking interface 210 may have a negative pressure to drive the cup cover 12 to open the dust discharge port 111, and the first filtering part 21 rotates under the action of the airflow drive. After the dust cup 10 is docked with the docking interface 210, the docking interface 210 generates a negative pressure to open the dust discharge port 111, and at the same time the first filtering part 21 rotates under the action of the airflow drive. On the one hand, the cleaning of the garbage in the cup body 11 is realized, and on the other hand, the cleaning of the first filtering part 21 is realized. There is no need to additionally set a cleaning mechanism for cleaning the first filtering part 21, the structure is simpler, the cost is lower, and the first filtering part 21 is not easily blocked, and the cleaning device 100 can continuously maintain a good cleaning effect.

[0098] Combined with Figures 8 to 11, the cleaning system 1000 according to the second aspect embodiment of the present invention includes: a base station 200 and the aforementioned cleaning device 100. The base station 200 has a dust collection air duct 220 and a bypass air duct 230 that communicate with each other; the cleaning device 100 is separable and dockable with the base station 200. The cleaning device 100 has an air inlet air duct 31, a return air duct 32, and a suction air duct 33. Among them, the cleaning device 100 has a working mode and a self-cleaning mode. In the working mode, the air inlet air duct 31 communicates with the dust cup 10, and the dust cup 10 communicates with the suction air duct 33; in the self-cleaning mode, the air inlet air duct 31 communicates with the dust cup 10, the dust cup 10 communicates with the dust collection air duct 220, and the bypass air duct 230 communicates with the suction air duct 33.

[0099] Exemplarily, in combination with Figure 9 , the arrows show the flow direction of the air flow of the cleaning device 100 in the working mode. The cleaning device 100 may include a suction device. In the working mode, the suction device communicates with the dust cup 10. Dirt such as dust, hair, and debris on the working surface is inhaled into the dust cup 10 through the air inlet air duct 31. The cup cover 12 closes the ash discharge port 111 to keep the dust cup 10 in a closed state. The filtering device 20 filters the air flow, and the clean air flow after dust filtration is discharged from the suction air duct 33 outside the cleaning device 100 through the suction device. In combination with Figure 11 , when the cleaning device 100 finishes the cleaning work, the cleaning device 100 can be docked with the base station 200. In the self-cleaning mode of the cleaning device 100, the cup cover 12 opens the ash discharge port 111 to connect the dust cup 10 with the dust collection air duct 220, and the bypass air duct 230 communicates with the suction air duct 33. Under the action of the suction device, a negative pressure is generated in the base station 200, so that dirt such as dust, debris, and hair in the dust cup 10 is collected into the dust bag 240 of the base station 200. The air flow in the base station 200 flows back to the return air duct 32 of the cleaning device 100 through the bypass air duct 230, and finally is discharged from the suction air duct 33. By providing the bypass air duct 230 on the base station 200 and the return air duct 32 on the cleaning device 100, the base station 200 does not need to be provided with a motor. By introducing negative pressure into the base station 200 by means of the suction device of the cleaning device 100, a negative pressure is generated in the base station 200. The negative pressure in the base station 200 can clean and collect dirt from the dust cup 10 of the cleaning device 100, simplify the structure of the base station 200, and reduce the noise of the base station 200 during operation.

[0100] In combination with Figure 9 , where, in the working mode, the cup cover 12 closes the ash discharge port 111, and the second filtering part 22 locks the first filtering part 21, and the first filtering part 21 does not rotate. At this time, the first filtering part 21 and the second filtering part 22 cooperate to filter the air flow entering the dust cup 10.

[0101] In combination with Figure 11, Further, in the self-cleaning mode, the air flow circulates along the air inlet duct 31, the dust cup 10, the dust collection duct 220, the bypass duct 230, the return duct 32 and the suction duct 33, and drives the first filter unit 21 to rotate. That is to say, the air flow entering the dust cup 10 in the self-cleaning mode can be utilized to drive the first filter unit 21 to rotate. Specifically, in the working mode, when the dust-containing air flow enters the dust cup 10 through the air inlet duct 31, a high-speed rotating air flow is formed in the dust cup 10, and filaments such as hair are easily wound around the outer side of the first filter unit 21. When the cleaning device 100 is in the self-cleaning mode, the second filter unit 22 releases the first filter unit 21, and the first filter unit 21 can rotate around the axial direction. The air flow entering the dust cup 10 through the near air duct 31 can drive the first filter unit 21 to rotate, so that the filaments such as hair wound around the first filter unit 21 in the working mode can be loosened, and the filaments are more likely to fall off. Among them, the first filter unit 21 is driven by the air flow entering the dust cup 10, so its rotation direction is the same as the rotation direction of the air flow entering the dust cup 10, and thus is also the same as the rotation direction of the hair wound by the air flow. Compared with the situation where the first filter unit 21 does not rotate, when the air flow rotates a certain number of circles in the dust cup 10, when the first filter unit 21 rotates, theoretically, the number of circles that the hair rotates relative to the first filter unit 21 is less, that is, the number of circles of hair winding is also lower. Therefore, it is more conducive to the separation of the hair from the first filter unit 21. In the self-cleaning mode, the cleaning device 100 can improve the cleaning effect on the filter device 20, without additionally setting a structure for cleaning the filter device 20, thereby reducing the situation that the hair winding blocks the first filter unit 21 and affects the filtering efficiency.
