[0036] The following disclosure provides many different embodiments or examples for realizing different structures of the present invention. To simplify the description of the present invention, the components and setups of specific examples are described below. Of course, these are illustrative and not intended to limit the present invention. Furthermore, the present invention does not indicate relationships between the various embodiments and / or setups described, and for the purpose of simplification and clarification, reference numbers and / or reference letters may be repeated in different examples. In addition, while the present invention provides examples of various specific processes and materials, those skilled in the art can be aware of the application of other processes and / or the use of other materials.

[0037] One embodiment of the present invention provides a dust cup unit 100, which, as shown in Figures 1 and 2, comprises a cup body 10 and a dust separation unit 20. The cup body 10 comprises a storage chamber 10a, an air intake port 10b and an exhaust port 10c, with an airflow path formed between the air intake port 10b and the exhaust port 10c. The storage chamber 10a comprises a first dust collection chamber 10aa communicating with the air intake port 10b, and the first dust collection chamber 10aa is located on the bottom side of the air intake port 10b.

[0038] The dust separation unit 20 comprises a fine dust separator 22 and a separation section 21. At least a portion of the fine dust separator 22 is located in the airflow path, causing the airflow entering from the intake port 10b to flow along the airflow path by rotation. The separation section 21 is located in the first dust collection chamber 10aa and is installed eccentrically with respect to the first dust collection chamber 10aa. The outer diameter of the separation section 21 gradually decreases from one end closer to the fine dust separator 22 to the other end further away from the fine dust separator 22.

[0039] Specifically, the dust separation unit 20 is installed in the containment chamber 10a and is for separating dust from the airflow. The airflow path from the intake port 10b to the exhaust port 10c passes through at least a portion of the flow area of ​​the fine dust separator 22, and the airflow in the airflow path is in rotational motion.

[0040] The specific configuration of the separation unit 21 is not limited. For example, as shown in Figure 2, the separation unit 21 is a dust collector having a second dust collection chamber 21a that communicates with the dust separator 22.

[0041] Specifically, the second dust collection chamber 21a is used to collect fine dust in the airflow along the airflow path. The dust collector can collect fine dust and also disrupt the airflow motion in the first dust collection chamber 10aa.

[0042] The dust separator 22 can be centered over the containment chamber 10a so as to prevent the dust separation unit 20 from interfering with the rotational motion of the airflow along the airflow path. Of course, depending on the actual situation, the two can also be installed eccentrically.

[0043] The dust separator 22 may have only a portion of its area located in the airflow path, or it may have all of its area located in the airflow path.

[0044] Furthermore, the specific structure of the dust separator 22 can be configured according to the actual situation.

[0045] Exemplary, as shown in Figures 2 and 3, the dust separator 22 comprises an airflow guide member 221 and a dust guide member 222. The airflow guide member 221 has a first airflow passage 221a, and the dust guide member 222 has a second airflow passage 222a. The airflow guide member 221 is located at one end of the dust guide member 222 away from the dust collector. The first airflow passage 221a communicates with the exhaust port 10c, and the second airflow passage 222a communicates with the second dust collection chamber 21a.

[0046] Furthermore, the installation position of the air intake port 10b on the cup body 10 must satisfy the requirement that it be able to rotate around the central axis of the containment chamber 10a after the airflow has flowed into the containment chamber 10a. For example, the air intake port 10b is provided on the side wall of the cup body 10.

[0047] The operating principle of the dust cup unit 100 of the present invention will be explained using Figure 2 as an example. After the airflow containing dust flows from the intake port 10b into the containment chamber 10a, it rotates along the side wall of the containment chamber 10a. Some of the dust in the airflow (mainly dust with relatively coarse particles) is thrown towards the side wall of the containment chamber 10a by centrifugal force and its own gravity, and falls into the first dust collection chamber 10aa while rotating along the side wall of the containment chamber 10a. The remaining portion of the relatively fine dust enters the fine dust separator 22 along the airflow path. Thus, separation of some of the dust from the airflow can be achieved. Furthermore, the airflow that enters the fine dust separator 22 continues to rotate along the airflow path so as to rotate along the side wall of the first guide passage 221a, and is discharged from the exhaust port 10c. The dust that enters the dust separator 22 moves towards the bottom side of the second flow guide passage 222a, rotating along the side wall due to gravity and centrifugal force, and is collected in the second dust collection chamber 21a. Thus, the airflow and dust that enter the dust separator 22 can be moved in opposite directions, and further separation of dust and airflow can be achieved.

[0048] The separation unit 21 is installed eccentrically with respect to the first dust collection chamber 10aa. In other words, the centers of the two, for example, their central axes, do not coincide.

[0049] The rotating airflow along the airflow path easily forms an airflow that rotates and moves towards the top within the first dust collection chamber 10aa. Therefore, by installing the separation unit 21 eccentrically with respect to the first dust collection chamber 10aa, the rotational motion of the airflow in the first dust collection chamber 10aa is obstructed and the airflow is disturbed, thereby preventing the dust collected in the first dust collection chamber 10aa from being stirred up again.

[0050] Furthermore, the reason why the region of the dust separation unit of the present invention located within the first dust collection chamber 10aa is installed eccentrically with respect to the first dust collection chamber 10aa is to obtain the effect of turbulence. If other structures were added to the outside of the separation section 21, and the center of the entire structure coincided with the center of the first dust collection chamber 10aa, the effect of turbulence would not be obtained.

[0051] Furthermore, the separation unit 21 of the present invention does not directly block the airflow motion through its structure, but rather the centers of the separation unit 21 and the first dust collection chamber 10aa (which are actually also the centers of the rotational motion of the airflow) do not overlap. By disrupting the upward rotational motion of the airflow, it prevents dust in the first dust collection chamber 10aa from being stirred up again, thereby enhancing the dust collection effect.

[0052] This allows the external dimensions of the separation unit 21 to be gradually reduced from one end closer to the dust separator 22 to the other end further away from the dust separator 22, thereby ensuring a turbulent flow effect at the end of the separation unit 21 closer to the dust separator 22, while simultaneously maximizing the space for collecting dust in the first dust collection chamber 10aa to facilitate dust collection.

[0053] The specific shape of the separation section 21 is not limited and may be, for example, a cone or a frustocone.

[0054] In another embodiment of the present invention, a cleaning device 1000 is provided, comprising a main body and a dust cup unit 100 described in any embodiment of the present invention, wherein the dust cup unit 100 is installed on the main body.

[0055] Another embodiment of the present invention provides a cleaning system 10000 comprising a base station and a cleaning device 1000 as described in any embodiment of the present invention, wherein the base station is used to dock with the cleaning device 1000.

[0056] Specifically, the cleaning device 1000 is a cleaning appliance that can perform cleaning functions such as a vacuum cleaner.

[0057] The base station is a device that comes as a set with the cleaning device 1000. The base station can dock with the cleaning device 1000 and is used to collect the dust and debris absorbed by the dust cup unit 100. Of course, the base station may have other functions depending on the actual situation. For example, the base station can also be used to charge the cleaning device 1000 by docking with it.

[0058] The dust cup unit 100 according to an embodiment of the present invention comprises a cup body 10 and a dust separation unit 20, with an airflow path formed between the intake port 10b and the exhaust port 10c of the cup body 10. On the one hand, at least a portion of the area of ​​the fine dust separator 22 of the dust separation unit 20 is located in the airflow path, causing the airflow flowing in from the intake port 10b to flow along the airflow path by rotation. As a result, by providing the fine dust separator 22, dust and airflow can be separated, and the dust cup unit 100 will have a good dust separation effect. On the other hand, the separation section 21 of the dust separation unit 20 is located in the first dust collection chamber 10aa and is installed eccentrically with respect to the first dust collection chamber 10aa, thereby disrupting the airflow within the first dust collection chamber 10aa, and preventing the dust in the first dust collection chamber 10aa from being stirred up again by the rotating airflow, thus further enhancing the dust separation effect. At the same time, the external dimensions of the separation unit 21 gradually decrease from one end closer to the dust separator 22 to the other end further away from the dust separator 22. This enhances the turbulent flow effect at the end of the separation unit 21 closer to the dust separator 22, making it easier to collect dust that has fallen into the first dust collection chamber 10aa and further improving the dust separation effect. As a result, the present invention creates turbulence by eccentrically installing the beads rather than by adding beads, eliminating the problem of dust getting entangled in the beads. This ensures that the dust cup unit 100 has a high dust separation effect, while also making it easier to clean and dispose of the dust cup unit 100.

[0059] In one specific embodiment, the containment chamber 10a comprises a first dust collection chamber 10aa and a separation chamber for providing an airflow path, and the first dust collection chamber 10aa and the separation chamber are coaxial, that is, their centers coincide.

[0060] Of course, depending on the actual situation, the two do not necessarily have to be coaxial; that is, their centers do not overlap.

[0061] In one embodiment, as shown in Figure 2, the dust separator 22 is installed coaxially with the first dust collection chamber 10aa.

[0062] specifically, Separation part 21 It is installed eccentrically with respect to the first dust collection chamber 10aa. Fine dust separator 22 The first dust collection chamber 10aa is installed coaxially with the dust separation unit 20, meaning their centers lie on the same axis. In other words, the fine dust separator 22 is not coaxial with the separation unit 21, meaning their centers do not lie on the same axis. By offsetting them relatively, it is possible to further prevent the airflow in the first dust collection chamber 10aa from rotating around the dust separation unit 20 and moving towards the top, thereby strengthening the separation effect between dust and airflow.

[0063] In one embodiment, as shown in Figure 2, the dust separation unit 20 includes a filtration unit 23 provided on the outer periphery of the fine dust separator 22, and at least a portion of the fine dust separator 22 and at least a portion of the filtration unit 23 are located in the airflow path.

[0064] Specifically, the filtration unit 23 may be located in the airflow path in only a portion of its area, or all of its area may be located in the airflow path. The airflow entering from the intake port 10b passes through the filtration unit 23 and the fine dust separator 22 in sequence while rotating, and is then discharged through the exhaust port 10c.

[0065] The filtration unit 23 is used to separate dust in the airflow along the airflow path, for example, a filter cage. That is, the filtration unit 23 can be used to block hair, fibers, and coarse dust, and the size of its pores determines the size of the dust that can pass through the filtration unit 23 and enter the fine dust separator 22.

[0066] By providing the filtration unit 23 on the outer circumference of the dust separator 22, it is possible to prevent a large amount of dust from entering the dust separator 22. This prevents excessive dust from reducing the separation effect of the dust separator 22 and mixing excessive dust into the airflow discharged from the exhaust port 10c, thus ensuring the dust separation effect.

[0067] In a specific embodiment, the filtration unit 23, the dust separator 22, and the containment chamber 10a all overlap at their centers, while the dust collector is installed eccentrically with respect to the first dust collection chamber 10aa.

[0068] In a specific embodiment, the dust collector is located on the bottom side of the dust guide member 222, the airflow guide member 221 is located on the top side of the dust guide member 222, and the exhaust port 10c is located on the top side of the airflow guide member 221.

[0069] In one embodiment, as shown in Figure 2, the dust separation unit 20 is equipped with a dust cover 24 located away from the exhaust port 10c of the filtration unit 23, and a first dust collection chamber 10aa is defined between the dust cover 24 and the bottom wall of the cup body 10.

[0070] Specifically, the dust cover 24 is located between the filtration unit 23 and the first dust collection chamber 10aa, preventing dust from being stirred up again by the airflow in the first dust collection chamber 10aa, thereby enhancing the separation effect against dust in the airflow.

[0071] Furthermore, in order to facilitate the dust falling into the first dust collection chamber 10aa due to centrifugal force and gravity, a gap exists between the dust cover 24 and the side wall of the cup body 10, and the specific structure of this gap is not limited.

[0072] For example, the dimensions of the cross-section of the dust cover 24 gradually increase from the side farther from the first dust collection chamber 10aa to the side closer to the first dust collection chamber 10aa. This reduces the influence of the dust cover 24 on dust falling into the first dust collection chamber 10aa, enhances the blocking effect of the dust cover 24 on dust inside the first dust collection chamber 10aa, and prevents dust inside the first dust collection chamber 10aa from being stirred up again.

[0073] In one embodiment, as shown in Figure 2, one end of the airflow guide member 221 closest to the dust guide member 222 enters the second flow passage 222a and is installed with a gap between it and the side wall of the second flow passage 222a, with the gap forming a vent 22a. The intake port 10b communicates with the exhaust port 10c and the second dust collection chamber 21a via the vent 22a.

[0074] Specifically, the airflow that has passed through the filtration unit 23 first rotates around the outer wall surface of the airflow guide member 221, moves towards the bottom, and passes through the vent 22a. Then, it enters the first guide passage 221a from the bottom end and moves to the exhaust port 10c while rotating along the side wall of the first guide passage 221a. Dust (e.g., fine dust) mixed in the airflow rotates around the outer wall surface of the airflow guide member 221 in accordance with the airflow and passes through the vent 22a, and then moves towards the bottom towards the second dust collection chamber 21a while rotating along the side wall of the second guide passage 222a due to centrifugal force and gravity.

[0075] The specific shapes of the first flow guide passage 221a and the second flow guide passage 222a are not limited; for example, the first flow guide passage 221a is formed in a cylindrical shape so that the airflow can easily rotate within the first flow guide passage 221a.

[0076] Furthermore, as shown in Figures 2 and 3, the second flow guide passage 222a gradually contracts from the side furthest from the dust collector towards the side closer to the dust collector.

[0077] In other words, by reducing the cross-sectional area of ​​the second flow guide passage 222a, dust can be guided more concentratedly into the second dust collection chamber 21a, and at the same time, the cross-sectional area of ​​the communication point between the second flow guide passage 222a and the second dust collection chamber 21a can be reduced, which prevents dust in the second dust collection chamber 21a from being stirred up again and improves the dust separation effect in the airflow.

[0078] The specific structural shape of the second flow guide passage 222a is not limited and may be conical or frustoconical in shape to facilitate dust falling into the second dust collection chamber 21a.

[0079] The specific structural shape of the second dust collection chamber 21a can be determined by the external dimensions of the separation section 21, and may be, for example, a cone or a frustocone.

[0080] For example, the second dust collection chamber 21a gradually expands from the side furthest from the dust guide member 222 towards the side closer to the dust guide member 222.

[0081] In one embodiment, as shown in Figure 2, one end of the dust guide member 222 closest to the fine dust collector enters the second dust collection chamber 21a.

[0082] On the one hand, while the overall dimensions of the dust cup unit 100 remain unchanged, the length of the second air guide passage 222a can be made as large as possible to prevent dust from easily being blown up and re-moved by the airflow due to the second air guide passage 222a being too short. On the other hand, the turbulent effect of the dust collector on the airflow in the first dust collection chamber 10aa can be ensured without reducing the dimensions of the dust collector.

[0083] Furthermore, the dust collector may be installed eccentrically with respect to the dust guide member 222. This ensures that the dust collector is installed eccentrically with respect to the first dust collection chamber 10aa, while simultaneously maintaining the alignment of the centers of the dust guide member 222 and the containment chamber 10a. At the same time, the dust guide member 222 can also create turbulence within the second dust collection chamber 21a, preventing the dust in the second dust collection chamber 21a from being stirred up again.

[0084] In one embodiment, as shown in Figure 2, the dust separator 22 further includes a partition member 223 located between the airflow guide member 221 and the exhaust port 10c. The partition member 223 is installed with a gap between it and the end face of the airflow guide member 221 on the side closer to the exhaust port 10c, and a third flow guide passage 22b is formed at the gap, connecting the exhaust port 10c and the first flow guide passage 221a.

[0085] Specifically, by providing the partition member 223, a third flow guide passage 22b is formed between the partition member 223 and the airflow guide member 221, thereby extending the airflow path. At the same time, the shielding effect of the partition member 223 allows dust in the airflow to be easily separated as it moves along the third flow guide passage 22b, ensuring the cleanliness of the airflow discharged from the exhaust port 10c.

[0086] The specific shapes of the partition member 223 and the airflow guide member 221 are not limited.

[0087] Exemplary, the airflow guide member 221 comprises a cylindrical body having a first flow guide passage 221a and an end face located on the side of the cylindrical body closer to the exhaust port 10c. A third flow guide passage 22b is formed in the space between the partition member 223 and the end face, and a portion of the partition member 223 enters the first flow guide passage 221a, guiding the airflow to move along the third flow guide passage 22b by rotation.

[0088] In a specific embodiment, the cup body 10 includes a dust outlet located at the bottom of the first dust collection chamber 10aa, and a lid that can be opened and closed and fitted over the dust outlet.

[0089] A vacuum cleaner is a common cleaning device that can generate very strong suction to draw dust or foreign objects accumulated on the surface of floors, carpets, walls, or other objects into a dust cup device.

[0090] However, dust cup devices in related technologies are unable to separate some small dust particles, which are then discharged with the airflow, affecting the motor's lifespan and polluting the environment.

[0091] As shown in Figure 4, an embodiment of the present invention provides a dust cup unit 100, the cleaning unit comprising a cup body 10, a filtration unit 23, and a plurality of dust guide members 222.

[0092] Specifically, the cup body 10 may be a hollow housing such as a cylinder or a rectangle. The material of the cup body 10 may include, but is not limited to, plastic or metal. The cup body 10 has a first dust collection chamber 10aa and a plurality of second dust collection chambers 21a, and the plurality of second dust collection chambers 21a are located within the first dust collection chamber 10aa. The first dust collection chamber 10aa and the second dust collection chambers 21a are used to collect dust, and the centers of the plurality of second dust collection chambers 21a do not overlap with the centers of the first dust collection chamber 10aa. For example, as shown in Figure 5, there may be four second dust collection chambers 21a, and the centers of the four second dust collection chambers 21a are positioned to surround the center of the first dust collection chamber 10aa.

[0093] The cup body 10 can house the filtration unit 23 and a plurality of dust guide members 222, with the inlets of the plurality of dust guide members 222 communicating with the outlets of the filtration unit 23, and the outlets of each dust guide member 222 communicating with one second dust collection chamber 21a. That is, the number of dust guide members 222 and the number of second dust collection chambers 21a are the same, and the present invention shows an example where there are four dust guide members 222 and four second dust collection chambers 21a. The filtration unit 23 is configured to centrifuge some of the dust into the first dust collection chamber 10aa by centrifuging the dust, while the remaining dust enters the dust guide members 222 along the outlet of the filtration unit 23, is centrifuged in the dust guide members 222, and then falls into the second dust collection chamber 21a. In other words, the dust is sucked into the filtration unit 23, and due to the suction force, the dust undergoes centrifugal motion within the filtration unit 23. Some of the heavier dust is centrifuged into the first dust collection chamber 10aa, while the remaining lighter dust is centrifuged along the filtration unit 23 to the dust guide member 222, where it is centrifuged again before falling into the multiple second dust collection chambers 21a.

[0094] The center of the first dust collection chamber 10aa is the center of the cup body 10. That is, the centers of the multiple second dust collection chambers 21a are positioned to surround the center of the cup body 10. The outlet of each dust guide member 222 communicates with one second dust collection chamber 21a, and all of the multiple dust guide members 222 are positioned close to the center of the cyclone separation. In this way, lighter debris located at the center of the cyclone separation falls into the multiple dust guide members 222 and can be collected in the multiple second dust collection chambers 21a. By positioning the centers of the multiple second dust collection chambers 21a to surround the center of the first dust collection chamber 10aa, the dust collection efficiency of the second dust collection chambers 21a is increased.

[0095] As shown in Figure 6, the filtration unit 23 can be set to a regular or irregular shape, such as cylindrical or conical. The filtration unit 23 is located inside the cup body 10 and is provided with a plurality of through holes 23a, which are arranged on the side walls of the filtration unit 23 and form a filter structure. Debris inside the filtration unit 23 can enter the first dust collection chamber 10aa through the through holes 23a. The material of the filtration unit 23 includes, but is not limited to, plastic or metal. A metal filtration unit 23 generates less static electricity during operation than a plastic filtration unit 23, effectively reducing dust adhering to the filtration unit 23 and preventing the through holes 23a from being blocked by adhering dust.

[0096] As shown in Figure 5, multiple dust guide members 222 are arranged adjacently to form an annular body, and multiple second dust collection chambers 21a are arranged adjacently, with the second dust collection chambers 21a fitted into the dust guide members 222. The annular body is installed with a gap between it and the filtration unit 23, and a containment space 222b is formed between the annular body and the filtration unit 23, allowing dust to undergo centrifugal motion within the containment space 222b. The containment space 222b communicates with the first dust collection chamber 10aa via a through hole 23a. The second dust collection chambers 21a and the dust guide members 222 may be integrally molded structures or separate molded structures. Each dust guide member 222 communicates with one second dust collection chamber 21a, and the second dust collection chambers 21a can contain the dust in the dust guide members 222.

[0097] As shown in Figure 7, the cup body 10 includes a dust box 11 and a bottom cover 12. The bottom cover 12 can be hinged to the dust box 11, and the bottom cover 12 is installed on the dust box 11 so as to be openable and closable. When the bottom cover 12 is placed over the dust box 11, the first dust collection chamber 10aa is closed so that the dust separated by the filtration unit 23 can be contained in the first dust collection chamber 10aa, and the second dust collection chamber 21a is closed so that the dust separated by the dust guide member 222 can be contained in the second dust collection chamber 21a.

[0098] As shown in combination with Figure 8, embodiments of the present invention further provide a cleaning device 1000. The dust cup unit 100 described above can be used in the cleaning device 1000, or the cleaning device 1000 may be equipped with the dust cup unit 100 described above.

[0099] In the dust cup unit 100 and cleaning device according to an embodiment of the present invention, a cup body 10, a filtration unit 23, and a plurality of dust guide members 222 are provided, and the cup body 10 is designed to have a first dust collection chamber 10aa and a plurality of second dust collection chambers 21a. As a result, when the cleaning device 1000 sucks dust into the filtration unit 23, the centrifugal action of the filtration unit 23 causes larger dust particles to pass through the through-holes 23a of the filtration unit 23 and fall into the first dust collection chamber 10aa, while smaller dust particles enter the dust guide members 222 through the outlet of the filtration unit 23, and the centrifugal action of the dust guide members 222 causes the smaller dust particles to fall into the plurality of second dust collection chambers 21a. In this way, by providing the filtration unit 23 and the dust guide member 222, the waste is separated twice, and small-particle dust is discharged with the airflow, thus avoiding environmental pollution and preventing an impact on the service life of the cleaning equipment 1000, thereby improving the quality of the cleaning equipment 1000.

[0100] The cleaning device 1000 is used to clean up debris, for example, the cleaning device 1000 is a device for cleaning dust such as a handheld vacuum cleaner, and embodiments of the present invention will be described using a handheld vacuum cleaner as an example.

[0101] The dust cup unit 100 is located inside the cleaning device 1000 and is used to collect and contain the dust sucked in by the cleaning device 1000.

[0102] As shown in conjunction with Figure 7, the dust cup unit 100 further includes a locking member 30 located at one end near the bottom lid 12 of the dust box 11. The locking member 30 is configured to hold the bottom lid 12 in place. That is, the locking member 30 is used to prevent the bottom lid 12 from opening due to gravity. For example, the locking member 30 can engage with the bottom lid 12, and the user can manually release the locking member 30. The locking member 30 can also be magnetically attracted to the bottom lid 12. When the bottom lid 12 is subjected to other forces that overcome the magnetic attraction, the bottom lid 12 opens. The specific installation of the locking member 30 can be set according to the actual situation and is not limited thereto.

[0103] As shown in Figure 6, in some examples, an air intake port 10b is formed in the cup body 10, and the air intake port 10b is connected to the filtration unit 23. When the cleaning device 1000 is in operation, the cleaning device 1000 can suck in air containing dust. The air containing dust enters the filtration unit 23 through the air intake port 10b. After the air containing dust enters the filtration unit 23, it rotates, generating centrifugal force, and the larger particles of dust in the air are driven through the through-hole 23a by the centrifugal force. First dust collection chamber 10aa It falls inward. The dust-containing air enters the dust guide member 222, taking the remaining smaller dust particles with it. As the dust-containing air enters the dust guide member 222, centrifugal force is generated, and the smaller dust particles each fall in multiple directions. 2nd dust collection chamber 21a It falls to the ground, and the remaining almost clean air is discharged into the outside environment.

[0104] As shown in combination with Figure 9, in some other examples, the air intake 10b is provided facing the filtration unit 23 and communicates with the first dust collection chamber 10aa. That is, when the cleaning device 1000 is in operation, the dust-containing air sucked in by the cleaning device 1000 enters the first dust collection chamber 10aa, where centrifugal force is generated. The larger dust particles in the dust-containing air fall into the first dust collection chamber 10aa, while the remaining dust passes through the through-hole 23a and enters the filtration unit 23. Due to centrifugal force, the dust-containing air, along with the remaining smaller dust particles, enters the multiple dust guide members 222. The dust-containing air rotates and separates at the dust guide members 222, and the smaller dust particles each fall into the multiple second dust collection chambers 21a. In this way, the air containing dust sucked in by the cleaning device 1000 is subjected to multiple centrifugal separations, preventing small-particle dust particles from being discharged with the airflow and polluting the environment, while also avoiding any impact on the service life of the cleaning device 1000, thereby improving the quality of the cleaning device 1000.

[0105] As shown in Figure 8, an embodiment of the present invention provides a cleaning system 10000 comprising a dust collection station 2000 and cleaning equipment 1000.

[0106] Specifically, the dust collection station 2000 is used to collect dust contained in the cleaning equipment 1000. The dust collection station 2000 comprises a butt joint member 210 and a dust collection chamber 220. The butt joint member 210 may be funnel-shaped. The inlet of the butt joint member 210 is connected to the dust box 11. The dimensions of the inlet of the butt joint member 210 are larger than the dimensions of the bottom lid 12 of the cup body 10, so that the bottom lid 12 can be opened inside the butt joint member 210. The outlet of the butt joint member 210 is connected to the dust collection chamber 220, that is, the dust collection chamber 220 is connected to the cup body 10 via the butt joint member 210. The dust collection chamber 220 may be a device for collecting dust, such as a dust collection bag, dust collection cup, or dust collection 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 contain dust, and the dust stored in the first dust collection chamber 10aa and the second dust collection chamber 21a can fall into the dust collection chamber 220 via the abutting member 210.

[0107] In some cases, after the cleaning of the cleaning device 1000 is completed, the user sets the cleaning device 1000 in the dust collection station 2000 and engages the abutment member 210 with the dust box 11 of the dust cup unit 100. When it is necessary to clean the dust accumulated in the cleaning device 1000, the user can manually release the locking member 30 and open the bottom cover 12. The second dust collection chamber 21a and several first dust collection chambers 10aa are electrically connected to the abutment member 210, and the dust in the first dust collection chambers 10aa and the second dust collection chambers 21a can fall into the abutment member 210.

[0108] Furthermore, the dust collection station 2000 is further equipped with a suction motor 230 connected to the dust collection chamber 220. When the suction motor 230 is turned on, negative pressure is generated in the dust collection chamber 220, and dust in the first dust collection chamber 10aa and the second dust collection chamber 21a is sucked into the dust collection chamber 220 via the abutting member 210, thereby cleaning the first dust collection chamber 10aa and the second dust collection chamber 21a.

[0109] In some cases, the locking member 30 can be opened when negative pressure is present in the dust collection chamber 220. That is, when a user needs to clean the cleaning equipment 1000, the user can turn on the suction motor 230. The action of the suction motor 230 generates negative pressure in the dust collection chamber 220, which releases the locking member 30, opens the bottom cover 12, and sucks the dust in the first dust collection chamber 10aa and the second dust collection chamber 21a into the dust collection chamber 220.

[0110] Thus, in the cleaning system 10000, dust accumulated in the cleaning equipment 1000 can be cleaned by providing a dust collection station 2000. The dust collection station 2000 can be connected to the cleaning equipment 1000 by providing a butt joint member 210. The butt joint member 210 is connected to a dust collection chamber 220, the dust collection chamber 220 is connected to a suction motor 230, and the suction motor 230 sucks the dust from inside the cleaning equipment 1000 into the dust collection chamber 220 via the butt joint member 210, thereby cleaning the cleaning equipment 1000.
