Of course, they are merely examples and are not intended to limit the present invention.

[0059] An embodiment of the present application provides a dust cup assembly 100, as shown in Figures 1 and 2. The dust cup assembly 100 includes a cup body 10 and a dust separation assembly 20. The cup body 10 has a accommodating cavity 10a, an air inlet 10b, and an air outlet 10c. An air flow path is formed between the air inlet 10b and the air outlet 10c. The accommodating cavity 10a includes a first dust collecting cavity 10aa in communication with the air inlet 10b. The first dust collecting cavity 10aa is located at the bottom side of the air inlet 10b.

[0060] The dust separation assembly 20 includes a fine ash separator 22 and a separation portion 21. At least a portion of the fine ash separator 22 is located on the airflow path so that the airflow flowing in from the air inlet 10b flows along the airflow path through rotation. The separation portion 21 is located in the first dust collecting chamber 10aa and is eccentrically arranged relative to the first dust collecting chamber 10aa. The outer dimensions of the separation portion 21 gradually decrease from the end close to the fine ash separator 22 to the end away from the fine ash separator 22.

[0061] Specifically, the dust separation assembly 20 is disposed in the accommodating chamber 10a and is used to separate dust from the airflow. The airflow path from the air inlet 10b to the air outlet 10c passes through at least a portion of the fine dust separator 22, and the airflow on the airflow path is in a rotational motion.

[0062] The specific structure of the separation unit 21 is not limited. For example, referring to FIG2 , the separation unit 21 is a fine ash collector having a second dust collecting chamber 21 a , and the second dust collecting chamber 21 a is connected to the fine ash separator 22 .

[0063] Specifically, the second dust collecting chamber 21a is used to collect fine dust in the airflow flowing along the airflow path. While being able to collect fine dust, the fine dust collector can also disturb the airflow in the first dust collecting chamber 10aa.

[0064] The fine dust separator 22 and the accommodating chamber 10a may be centrally aligned to prevent the dust separation assembly 20 from interfering with the rotational motion of the airflow on the airflow path.

[0065] The fine ash separator 22 may have only a partial area located on the airflow path, or may have the entire area located on the airflow path.

[0066] In addition, the specific structure of the fine ash separator 22 can be set according to actual conditions.

[0067] For example, referring to Figures 2 and 3, the fine ash separator 22 includes an airflow guide 221 and a dust guide 222, the airflow guide 221 has a first guide channel 221a, the dust guide 222 has a second guide channel 222a, the airflow guide 221 is located at one end of the dust guide 222 away from the fine ash collector, the first guide channel 221a is connected to the air outlet 10c, and the second guide channel 222a is connected to the second dust collecting chamber 21a.

[0068] It should be noted that the air inlet 10b is positioned on the cup body 10 in a manner such that the airflow enters the accommodating cavity 10a and then rotates around the central axis of the accommodating cavity 10a. For example, the air inlet 10b is positioned on the side wall of the cup body 10.

[0069] Taking Figure 2 as an example, the working principle of the dust cup assembly 100 of the present application is described. After the dust-carrying airflow flows into the accommodating chamber 10a from the air inlet 10b, it will rotate along the side wall of the accommodating chamber 10a. Part of the dust in the airflow (mainly coarse ash with relatively coarse particles) will be thrown to the side wall of the accommodating chamber 10a under the action of centrifugal force and its own gravity, and will fall into the first dust collecting chamber 10aa while rotating along the side wall of the accommodating chamber 10a. Another part of the dust with relatively fine particles will enter the fine ash separator 22 along the airflow path. In this way, the separation of part of the dust and the airflow can be achieved. Furthermore, the airflow entering the fine ash separator 22 will continue to rotate along the airflow path, so as to rotate along the side wall of the first guide channel 221a, and be discharged from the air outlet 10c. The dust entering the fine ash separator 22, under the action of gravity and centrifugal force, rotates along the sidewalls of the second guide channel 222a while moving toward the bottom, and is collected in the second dust collecting chamber 21a. This allows the airflow and dust entering the fine ash separator 22 to move in opposite directions, further improving the separation of dust and airflow.

[0070] The separation portion 21 is eccentrically arranged relative to the first dust collecting chamber 10aa, which means that the centers of the two do not coincide with each other, such as the central axes of the two do not coincide with each other.

[0071] Driven by the rotating airflow flowing along the airflow path, an airflow that rotates and moves toward the top side is easily formed in the first dust collecting chamber 10aa. Therefore, by eccentrically positioning the separation portion 21 relative to the first dust collecting chamber 10aa, the rotating motion of the airflow in the first dust collecting chamber 10aa can be hindered, thereby disrupting the flow of the airflow and preventing the dust collected in the first dust collecting chamber 10aa from being re-entrained.

[0072] It should be noted that the dust separation assembly 20 of the present application is located in the first dust collecting chamber 10aa and is eccentrically arranged relative to the first dust collecting chamber 10aa in order to achieve the effect of turbulence. If other structures are added to the outside of the separation portion 21 so that the center of the entire structure coincides with the center of the first dust collecting chamber 10aa, the turbulence effect cannot be achieved.

[0073] In addition, the separation portion 21 of the present application does not directly block the airflow movement through the structure itself, but because the separation portion 21 does not coincide with the center of the first dust collecting chamber 10aa (which is actually the center of the airflow rotation movement), it disrupts the upward rotation movement of the airflow, thereby preventing the dust in the first dust collecting chamber 10aa from being raised again, which can improve the dust collection effect.

[0074] Therefore, by gradually reducing the outer dimensions of the separation part 21 from the end close to the fine ash separator 22 to the end away from the fine ash separator 22, the turbulence effect of the separation part 21 at the end close to the fine ash separator 22 can be ensured, and at the same time, the space for dust collection in the first dust collecting chamber 10aa can be increased as much as possible to facilitate dust collection.

[0075] The specific shape of the separation portion 21 is not limited, for example, a cone or a truncated cone.

[0076] Another embodiment of the present application provides a cleaning device 1000, which includes a body and the dust cup assembly 100 described in any embodiment of the present application, and the dust cup assembly 100 is arranged on the body.

[0077] Another embodiment of the present application provides a cleaning system 10000 , which includes a base station and the cleaning device 1000 described in any embodiment of the present application. The base station is used to interface with the cleaning device 1000 .

[0078] Specifically, the cleaning device 1000 is a cleaning appliance capable of performing a dust collection function, such as a vacuum cleaner.

[0079] The base station is a device that is compatible with the cleaning device 1000. The base station can be docked with the cleaning device 1000 to collect dust and garbage absorbed by the dust cup assembly 100. Of course, depending on the actual situation, the base station can also have other functions. For example, by docking with the cleaning device 1000, the base station can also be used to charge the cleaning device 1000.

[0080] The dust cup assembly 100 of the embodiment of the present application includes a cup body 10 and a dust separation assembly 20, and an air flow path is formed between the air inlet 10b and the air outlet 10c of the cup body 10. On the one hand, at least a part of the fine ash separator 22 of the dust separation assembly 20 is located on the air flow path, so that the air flow flowing in from the air inlet 10b flows along the air flow path by rotation. Thus, by providing the fine ash separator 22, the dust can be separated from the air flow, so that the dust cup assembly 100 has a better dust separation effect. On the other hand, the separation part 21 of the dust separation assembly 20 is located in the first dust collecting chamber 10aa and is eccentrically arranged relative to the first dust collecting chamber 10aa, which can disrupt the air flow in the first dust collecting chamber 10aa, thereby preventing the dust in the first dust collecting chamber 10aa from being re-lifted under the drive of the rotating air flow, thereby further improving the dust separation effect. At the same time, the outer dimensions of the separation portion 21 gradually decrease from the end close to the fine ash separator 22 to the end away from the fine ash separator 22, which can improve the turbulence effect at the end of the separation portion 21 close to the fine ash separator 22 and facilitate the dust to fall and be collected in the first dust collecting chamber 10aa, thereby further improving the dust separation effect. Therefore, the present application uses an eccentric setting to achieve turbulence, rather than adding ribs to achieve turbulence, and there will be no problem of dust hanging on the ribs. Therefore, while ensuring that the dust cup assembly 100 has a good dust separation effect, it can also facilitate the cleaning and emptying of the dust cup assembly 100.

[0081] In a specific embodiment, the accommodating chamber 10a includes a first dust collecting chamber 10aa and a separation chamber for setting an airflow path. The first dust collecting chamber 10aa and the separation chamber are coaxial, that is, the centers of the two coincide.

[0082] Of course, depending on the actual situation, the two may not be coaxial, that is, their centers do not coincide.

[0083] In one embodiment, referring to FIG. 2 , the fine ash separator 22 is coaxially disposed with the first dust collecting chamber 10aa.

[0084] Specifically, the fine ash separator 22 is eccentrically positioned relative to the first dust collecting chamber 10aa, while the separation unit 21 is coaxial with the first dust collecting chamber 10aa, meaning their centers are aligned on the same axis. In other words, the fine ash separator 22 and the separation unit 21 are not coaxial, meaning their centers are not aligned on the same axis. This relative offset further prevents the airflow in the first dust collecting chamber 10aa from rotating around the dust separation assembly 20 and moving toward the top, thereby enhancing the separation of dust and airflow.

[0085] In one embodiment, referring to FIG2 , the dust separation assembly 20 includes a filter assembly 23 , which is disposed on the outer periphery of the fine ash separator 22 , and at least a portion of the fine ash separator 22 and at least a portion of the filter assembly 23 are located on the airflow path.

[0086] Specifically, the filter assembly 23 may be partially located on the airflow path, or the entire area may be located on the airflow path. The airflow flowing in from the air inlet 10b rotates while passing through the filter assembly 23 and the fine ash separator 22 in sequence, and then discharged through the air outlet 10c.

[0087] The filter assembly 23 is used to separate dust from the airflow flowing along the airflow path, such as a filter cover. The filter assembly 23 can be used to block hair, fibers, and coarse dust, and its pore size determines the size of dust that can pass through the filter assembly 23 and enter the fine ash separator 22.

[0088] By arranging a filter assembly 23 on the outer peripheral side of the fine ash separator 22, excessive dust can be prevented from entering the fine ash separator 22, so as to prevent excessive dust from reducing the separation effect of the fine ash separator 22, so that the air flow discharged from the air outlet 10c is mixed with excessive dust, thereby ensuring the dust separation effect.

[0089] In a specific embodiment, the filter assembly 23, the fine ash separator 22 and the center of the accommodating chamber 10a all coincide with each other, and the fine ash collector is eccentrically arranged relative to the first dust collecting chamber 10aa.

[0090] In a specific embodiment, the fine ash collector is located at the bottom side of the dust guide 222 , the airflow guide 221 is located at the top side of the dust guide 222 , and the air outlet 10 c is located at the top side of the airflow guide 221 .

[0091] In one embodiment, referring to FIG. 2 , the dust separation assembly 20 includes a dust cover 24 , which is located on a side of the filter assembly 23 away from the air outlet 10 c , and a first dust collecting chamber 10 aa is defined between the dust cover 24 and the bottom wall of the cup body 10 .

[0092] Specifically, the dust shield 24 is located between the filter assembly 23 and the first dust collecting chamber 10aa, and can prevent dust from being re-lifted by the airflow in the first dust collecting chamber 10aa, thereby improving the dust separation effect in the airflow.

[0093] It should be noted that there is a space between the dust cover 24 and the side wall of the cup body 10, so that the dust can fall into the first dust collecting chamber 10aa under the action of centrifugal force and gravity, and its specific structure is not limited.

[0094] For example, the cross-sectional dimensions of the dust shield 24 gradually increase from the side away from the first dust collecting chamber 10aa toward the side closer to the first dust collecting chamber 10aa. This can reduce the impact of the dust shield 24 on dust falling into the first dust collecting chamber 10aa, improve the dust shield 24's ability to block dust in the first dust collecting chamber 10aa, and prevent dust in the first dust collecting chamber 10aa from being re-blown.

[0095] In one embodiment, please refer to Figure 2, one end of the airflow guide 221 close to the dust guide 222 extends into the second guide channel 222a, and is spaced apart from the side wall of the second guide channel 222a to form an air outlet 22a at the interval, and the air inlet 10b is connected to the air outlet 10c and the second dust collecting chamber 21a respectively through the air outlet 22a.

[0096] Specifically, the airflow passing through the filter assembly 23 first rotates around the outer wall of the airflow guide 221 and moves toward the bottom to pass through the air outlet 22a. It then enters the first guide channel 221a from the bottom and moves along the sidewalls of the first guide channel 221a while rotating to the air outlet 10c. Dust (such as fine dust) entrained in the airflow rotates around the outer wall of the airflow guide 221 and passes through the air outlet 22a. Then, under the influence of centrifugal force and gravity, it moves along the sidewalls of the second guide channel 222a while rotating toward the bottom, ultimately entering the second dust collection chamber 21a.

[0097] The specific shapes of the first guide channel 221a and the second guide channel 222a are not limited. For example, the first guide channel 221a is cylindrical to facilitate the rotation of the airflow in the first guide channel 221a.

[0098] For another example, referring to FIG. 2 and FIG. 3 , the second guide channel 222 a gradually contracts from a side away from the fine ash collector toward a side close to the fine ash collector.

[0099] That is to say, by shrinking the cross-sectional area of ​​the second guide channel 222a, the dust can be more concentratedly collected in the second dust collecting chamber 21a. At the same time, the cross-sectional area of ​​the connection between the second guide channel 222a and the second dust collecting chamber 21a can be reduced, which can prevent the dust in the second dust collecting chamber 21a from being raised again, and can improve the separation effect of dust in the airflow.

[0100] The specific structural shape of the second guide channel 222a is not limited, and it can be conical or truncated cone-shaped, which can facilitate dust to fall into the second dust collecting chamber 21a.

[0101] The specific structural shape of the second dust collecting chamber 21a can be determined according to the external dimensions of the separation portion 21, such as a cone or a truncated cone.

[0102] Exemplarily, the second dust collecting chamber 21 a gradually expands from a side away from the dust guide 222 toward a side close to the dust guide 222 .

[0103] In one embodiment, referring to FIG. 2 , one end of the dust guide 222 close to the fine dust collector extends into the second dust collecting chamber 21 a .

[0104] On the one hand, the length of the second guide channel 222a can be increased as much as possible without changing the overall size of the dust cup assembly 100, thereby preventing the second guide channel 222a from being too short, which would easily cause dust to be lifted and moved back with the airflow. On the other hand, the size of the fine dust collector will not be reduced, and the fine dust collector can ensure that it has a disturbing effect on the airflow in the first dust collecting chamber 10aa.

[0105] Furthermore, the fine dust collector can be positioned eccentrically relative to the dust guide 222. This ensures that the fine dust collector is positioned eccentrically relative to the first dust collecting chamber 10aa while maintaining center alignment between the dust guide 222 and the accommodating chamber 10a. Furthermore, the dust guide 222 can create a turbulent flow within the second dust collecting chamber 21a, further preventing dust within the second dust collecting chamber 21a from being re-entrained.

[0106] In one embodiment, referring to FIG2 , the fine ash separator 22 further includes a barrier 223 , which is located between the airflow guide 221 and the air outlet 10c . The barrier 223 and the end surface of the airflow guide 221 close to the air outlet 10c are spaced apart so that a third guide channel 22b is formed at the gap to connect the air outlet 10c and the first guide channel 221a .

[0107] Specifically, by setting the partition 223, a third guide channel 22b can be formed between the partition 223 and the airflow guide 221, so that the airflow path is extended. At the same time, due to the blocking effect of the partition 223, the dust in the airflow can be easily separated during the movement along the third guide channel 22b, thereby ensuring the cleanliness of the airflow flowing out of the air outlet 10c.

[0108] The specific shapes of the blocking member 223 and the airflow guide member 221 are not limited.

[0109] Illustratively, the airflow guide 221 includes a cylindrical body having a first guide channel 221a and an end surface located on the side of the cylindrical body near the air outlet 10c. A barrier 223 is spaced apart from the end surface to form a third guide channel 22b, and a portion of the barrier 223 extends into the first guide channel 221a to guide the airflow through rotation along the third guide channel 22b.

[0110] In a specific embodiment, the cup body 10 includes a dust outlet located at the bottom side of the first dust collecting chamber 10aa and a cover body that is openably and closably covered at the dust outlet.

[0111] A vacuum cleaner is a commonly used cleaning device that can generate very strong suction to suck dust or foreign matter accumulated on floors, carpets, walls, or other surfaces into a dust cup device.

[0112] However, the dust cup device in the related art cannot separate some dust particles with smaller particle sizes, which will be discharged with the air flow, affecting the service life of the motor and causing pollution to the environment.

[0113] Please refer to Figure 4. An embodiment of the present application provides a dust cup assembly 100, and the cleaning assembly includes a cup body 10, a filter assembly 23, and a plurality of dust guides 222.

[0114] Specifically, the cup body 10 can be a hollow shell such as a cylinder or a rectangle, and the material of the cup body 10 includes but is not limited to plastic, metal, etc. The cup body 10 is formed with a first dust collecting chamber 10aa and multiple second dust collecting chambers 21a. The multiple second dust collecting chambers 21a are located within the first dust collecting chamber 10aa. The first dust collecting chamber 10aa and the second dust collecting chamber 21a are used to collect garbage. The centers of the multiple second dust collecting chambers 21a do not coincide with the center of the first dust collecting chamber 10aa. For example, referring to FIG. 5 , the second dust collecting chamber 21a can include four, and the centers of the four second dust collecting chambers 21a are arranged around the center of the first dust collecting chamber 10aa.

[0115] The cup body 10 can accommodate a filter assembly 23 and multiple dust guides 222. The inlets of the multiple dust guides 222 are connected to the outlet of the filter assembly 23, and the outlet of each dust guide 222 is connected to a second dust collecting chamber 21a. That is, the number of dust guides 222 is the same as the number of second dust collecting chambers 21a. The dust guides 222 and second dust collecting chambers 21a of this application are illustrated in four examples. The filter assembly 23 is configured to centrifuge the garbage to centrifuge part of the garbage into the first dust collecting chamber 10aa, and the remaining garbage enters the dust guide 222 along the outlet of the filter assembly 23, and falls into the second dust collecting chamber 21a after being centrifuged by the dust guide 222. That is, the garbage is sucked into the filter assembly 23, and under the action of suction, the garbage performs centrifugal motion in the filter assembly 23. Some of the heavier garbage is centrifuged into the first dust collecting chamber 10aa, and the remaining lighter garbage is centrifuged along the filter assembly 23 to the dust guide 222, and falls into multiple second dust collecting chambers 21a after being centrifuged in the dust guide 222.

[0116] It should be noted that the center of the first dust collecting chamber 10aa is the center of the cup body 10, that is, the centers of the multiple second dust collecting chambers 21a are arranged around the center of the cup body 10, and the outlet of each dust guide 222 is connected to a second dust collecting chamber 21a, so that the multiple dust guides 222 are arranged close to the center of the cyclone separation. In this way, the lighter garbage located in the center of the cyclone separation can fall into the multiple dust guides 222, and thus be received by the multiple second dust collecting chambers 21a. The centers of the multiple second dust collecting chambers 21a are arranged around the center of the first dust collecting chamber 10aa, which improves the dust collection efficiency of the second dust collecting chamber 21a.

[0117] Referring to Figure 6 , the filter assembly 23 can be arranged in a regular or irregular shape, such as a cylinder or a cone. The filter assembly 23 is located within the cup body 10 and has a plurality of through-holes 23a disposed along the sidewalls of the filter assembly 23, forming a filter mesh structure. Trash within the filter assembly 23 can pass through the through-holes 23a and enter the first dust collection chamber 10aa. The materials of the filter assembly 23 include, but are not limited to, plastic and metal. Compared to plastic filter assemblies 23, metal filter assemblies 23 generate less static electricity during operation, effectively reducing dust adhesion to the filter assembly 23 and preventing clogging of the through-holes 23a by adhered dust.

[0118] Referring to Figure 5 , multiple dust guides 222 are adjacent to form an annular body, multiple second dust collecting chambers 21a are adjacent to each other, and the second dust collecting chambers 21a and dust guides 222 are arranged in conjunction with each other. The annular body and the filter assembly 23 are spaced apart, and a receiving space 222b is formed between the annular body and the filter assembly 23. Garbage can undergo centrifugal movement in the receiving space 222b, and the receiving space 222b is connected to the first dust collecting chamber 10aa via a through hole 23a. It should be noted that the second dust collecting chamber 21a and the dust guides 222 can be integrally formed or separately formed. Each dust guide 222 is connected to a corresponding second dust collecting chamber 21a, and the second dust collecting chamber 21a can accommodate garbage within the dust guide 222.

[0119] Please refer to Figure 7. The cup body 10 includes a dust barrel 11 and a bottom cover 12. The bottom cover 12 can be hinged to the dust barrel 11. The bottom cover 12 can be opened and closed on the dust barrel 11. When the bottom cover 12 is closed on the dust barrel 11, the first dust collecting chamber 10aa is closed, so that the first dust collecting chamber 10aa can accommodate garbage separated by the filter assembly 23, and the second dust collecting chamber 21a is closed, so that the second dust collecting chamber 21a can accommodate garbage separated by the dust guide 222.

[0120] Please refer to Figure 8. The embodiment of the present application also provides a cleaning device 1000. The above-mentioned dust cup assembly 100 can be used in the cleaning device 1000, or in other words, the cleaning device 1000 includes the above-mentioned dust cup assembly 100.

[0121] In the dust cup assembly 100 and the cleaning device of the embodiment of the present application, the cup body 10 forms a first dust collecting chamber 10aa and multiple second dust collecting chambers 21a through the cup body 10, the filter assembly 23 and the multiple dust guides 222. When the cleaning device 1000 sucks dust into the filter assembly 23, due to the centrifugal action of the filter assembly 23, the dust with larger particles passes through the through hole 23a of the filter assembly 23 and falls into the first dust collecting chamber 10aa, and the dust with smaller particles enters the dust guide 222 through the outlet of the filter assembly 23. Then, due to the centrifugal action of the dust guide 222, the dust with smaller particles falls into the multiple second dust collecting chambers 21a. In this way, the garbage is separated twice by setting the filter assembly 23 and the dust guide 222, which avoids the dust with smaller particles from being discharged with the airflow to pollute the environment, and also avoids affecting the service life of the cleaning device 1000, thereby improving the quality of the cleaning device 1000.

[0122] The cleaning device 1000 is used to clean up garbage. For example, the cleaning device 1000 can be a handheld vacuum cleaner or other device for cleaning dust. The embodiment of the present application is described using a handheld vacuum cleaner as an example.

[0123] The dust cup assembly 100 is located in the cleaning device 1000 and is used to collect and hold dust sucked in by the cleaning device 1000.

[0124] Referring to Figure 7 , the dust cup assembly 100 further includes a locker 30, which is located at one end of the dust cylinder 11 near the bottom cover 12. The locker 30 is configured to limit the bottom cover 12, that is, the locker 30 is used to prevent the bottom cover 12 from opening under the action of gravity. For example, the locker 30 can be engaged with the bottom cover 12, and the user can manually unlock the locker 30. The locker 30 can also be magnetically attracted to the bottom cover 12. When the bottom cover 12 is subjected to other forces that overcome the magnetic attraction, the bottom cover 12 opens. The specific configuration of the locker 30 can be configured according to actual conditions and is not limited here.

[0125] Referring to FIG6 , in some examples, the cup body 10 is formed with an air inlet 10b, which is connected to the filter assembly 23. When the cleaning device 1000 is in operation, the cleaning device 1000 can draw in dust-laden air, which then enters the filter assembly 23 through the air inlet 10b. After entering the filter assembly 23, the dust-laden air rotates and generates centrifugal force. Under the action of the centrifugal force, larger dust particles in the dust-laden air pass through the through-hole 23a and fall into the second dust collection chamber 21a. The dust-laden air then carries the remaining smaller dust particles into the dust guide 222. The centrifugal force generated by the dust-laden air entering the dust guide 222 causes the smaller dust particles to fall into the multiple first dust collection chambers 10aa, leaving the remaining nearly clean air to be discharged to the outside environment.

[0126] Referring to FIG9 , in other examples, the air inlet 10b is disposed toward the filter assembly 23 and is connected to the first dust collecting chamber 10aa. That is, when the cleaning device 1000 is operating, the dust-laden air inhaled by the cleaning device 1000 enters the first dust collecting chamber 10aa and rotates to generate centrifugal force. Dust particles with larger sizes in the dust-laden air fall into the first dust collecting chamber 10aa, while the remaining dust passes through the through-hole 23a and enters the filter assembly 23. Under the action of centrifugal force, the dust-laden air carries the remaining smaller dust particles into the multiple dust guides 222. The dust-laden air rotates and separates in the dust guides 222, causing the smaller dust particles to fall into the multiple second dust collecting chambers 21a. In this way, the dust-laden air inhaled by the cleaning device 1000 undergoes multiple centrifugal separations, preventing smaller dust particles from being discharged with the airflow and polluting the environment. This also prevents the service life of the cleaning device 1000 from being affected, thereby improving the quality of the cleaning device 1000.

[0127] Please refer to FIG. 8 . An embodiment of the present application further provides a cleaning system 10000 . The cleaning system 10000 includes a dust collection station 2000 and a cleaning device 1000 .

[0128] Specifically, the dust collection station 2000 is used to collect dust collected by the cleaning device 1000. The dust collection station 2000 includes a docking member 210 and a dust collection chamber 220. The docking member 210 can be funnel-shaped. The inlet of the docking member 210 is connected to the dust cylinder 11. The inlet size of the docking member 210 is larger than the size of the bottom cover 12 on the cup body 10, so that the bottom cover 12 can be opened in the docking member 210. The outlet of the docking member 210 is connected to the dust collection chamber 220. In other words, the dust collection chamber 220 is connected to the cup body 10 through the docking member 210. The dust collection chamber 220 can be a device for collecting dust, such as a dust bag, a dust cup, or a dust bucket. The dust collection chamber 220 can allow air to pass through but prevent dust from passing through. The dust collection chamber 220 is used to store dust. Dust stored in the first dust collection chamber 10aa and the second dust collection chamber 21a can fall into the dust collection chamber 220 through the docking member 210.

[0129] In some examples, after the cleaning device 1000 completes cleaning, the user places the cleaning device 1000 into the dust collection station 2000, and the docking piece 210 engages with the dust cylinder 11 of the dust cup assembly 100. When it is necessary to clean the dust stored in the cleaning device 1000, the user can manually unlock the lock 30, so that the bottom cover 12 opens, and the second dust collection chamber 21a and the plurality of first dust collection chambers 10aa are connected to the docking piece 210, so that the dust in the first dust collection chamber 10aa and the second dust collection chamber 21a can fall into the docking piece 210.

[0130] Furthermore, the dust collection station 2000 also includes a suction motor 230, which is connected to the dust collecting chamber 220. When the suction motor 230 is turned on, negative pressure is generated in the dust collecting chamber 220, so that the dust in the first dust collecting chamber 10aa and the second dust collecting chamber 21a is sucked into the dust collecting chamber 220 through the docking piece 210, thereby cleaning the first dust collecting chamber 10aa and the second dust collecting chamber 21a.

[0131] In some examples, the lock 30 can be opened when there is negative pressure in the dust collecting chamber 220. That is, when the user needs to clean the cleaning device 1000, the user can turn on the suction motor 230. Under the action of the suction motor 230, negative pressure is generated in the dust collecting chamber 220. Under the action of the negative pressure, the lock 30 is unlocked, the bottom cover 12 is opened, and the dust in the first dust collecting chamber 10aa and the second dust collecting chamber 21a is sucked into the dust collecting chamber 220.

[0132] In this way, the cleaning system 10000 can clean the dust stored in the cleaning device 1000 by setting up the dust collection station 2000. The dust collection station 2000 can be connected to the cleaning device 1000 by setting up the docking piece 210. The docking piece 210 is connected to the dust collecting chamber 220. The dust collecting chamber 220 is connected to the suction motor 230, so that the suction motor 230 can suck the dust in the cleaning device 1000 into the dust collecting chamber 220 through the docking piece 210, thereby cleaning the cleaning device 1000.
