[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, specific example components and configurations are described below. Of course, these are merely examples and are not intended to limit the present invention. Furthermore, the present invention does not imply a relationship between the various embodiments and / or configurations described, and reference numerals and / or characters may be repeated in different examples for the purposes of simplicity and clarity. Furthermore, while the present invention provides examples of various specific processes and materials, those skilled in the art may recognize 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, includes a cup body 10 and a dust separation unit 20. The cup body 10 includes a storage chamber 10a, an air inlet 10b, and an outlet 10c, with an airflow path formed between the air inlet 10b and the outlet 10c. The storage chamber 10a includes a first dust collection chamber 10aa that communicates with the air inlet 10b, and the first dust collection chamber 10aa is located below the air inlet 10b.

[0038] The dust separation unit 20 includes 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 and rotates the airflow flowing in from the air intake 10b along the airflow path. The separation section 21 is located in the first dust collection chamber 10aa and is installed eccentrically relative 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 farther from the fine dust separator 22.

[0039] Specifically, the dust separation unit 20 is provided in the storage chamber 10a and serves to separate dust from the airflow. The airflow path from the air intake 10b to the air exhaust 10c passes through at least a part of the flow area of ​​the fine dust separator 22, and the airflow in the airflow path rotates.

[0040] There are no particular limitations on the specific configuration of the separation unit 21. For example, as shown in FIG.

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

[0042] The fine dust separator 22 can be centered with the receiving chamber 10a so as to prevent the dust separating unit 20 from interfering with the rotational movement of the airflow on the airflow path. Of course, the two can also be installed eccentrically according to the actual situation.

[0043] The fine dust separator 22 may have only a partial area located in the airflow path, or may have the entire area located in the airflow path.

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

[0045] 2 and 3, the fine dust separator 22 includes an airflow guide member 221 and a dust guide member 222. The airflow guide member 221 has a first guide passage 221a, and the dust guide member 222 has a second guide passage 222a. The airflow guide member 221 is located at one end of the dust guide member 222 that is remote from the fine dust collector. The first guide passage 221a communicates with the exhaust port 10c, and the second guide passage 222a communicates with the second dust collecting chamber 21a.

[0046] The position of the air intake 10b on the cup body 10 must satisfy the requirement that the air intake 10b can rotate around the central axis of the container chamber 10a after the airflow has flowed into the container chamber 10a. For example, the air intake 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 described with reference to FIG. 2. After dust-laden airflow enters the storage chamber 10a through the air intake 10b, it rotates along the sidewall of the storage chamber 10a. Due to centrifugal force and its own gravity, some of the dust in the airflow (mainly relatively coarse particles) is thrown toward the sidewall of the storage chamber 10a and falls into the first dust collection chamber 10aa while rotating along the sidewall. The remaining relatively fine dust enters the fine dust separator 22 along the airflow path. This separates some of the dust from the airflow. The airflow entering the fine dust separator 22 continues its rotational motion along the airflow path, rotating along the sidewall of the first guide passage 221a, and is discharged through the exhaust port 10c. The dust that enters the fine dust separator 22 moves toward the bottom while rotating along the side wall of the second guide passage 222a due to gravity and centrifugal force, and is collected in the second dust collection chamber 21a. Thus, the airflow and dust that enter the fine dust separator 22 can move in opposite directions, further achieving separation of the dust and airflow.

[0048] The separating unit 21 is installed eccentrically with respect to the first dust collecting chamber 10aa, that is, the centers of the two, for example, the central axes of the two do not overlap.

[0049] The rotating airflow flowing along the airflow path tends to create an airflow that rotates and moves toward the top within first dust collection chamber 10aa. Therefore, by installing separation unit 21 eccentrically relative to first dust collection chamber 10aa, the rotational motion of the airflow in first dust collection chamber 10aa is hindered, disrupting the airflow and preventing the dust collected in first dust collection chamber 10aa from flying up again.

[0050] The area of ​​the dust separation unit of the present invention located within the first dust collection chamber 10aa is eccentrically positioned relative to the first dust collection chamber 10aa in order to obtain the effect of turbulence. If another structure were added outside the separation section 21 so that the center of the entire structure overlaps with the center of the first dust collection chamber 10aa, the effect of turbulence would not be obtained.

[0051] Furthermore, the separation section 21 of the present invention does not directly block the movement of the airflow by its structure itself, but rather disrupts the upward rotational movement of the airflow because the centers of the separation section 21 and the first dust collection chamber 10aa (which are actually the center of the rotational movement of the airflow) do not overlap, thereby preventing the dust in the first dust collection chamber 10aa from flying up again and improving the dust collection effect.

[0052] As a result, by gradually reducing the external dimensions of the separation section 21 from one end close to the fine dust separator 22 to the other end farthest from the fine dust separator 22, the turbulent flow effect at the one end of the separation section 21 close to the fine dust separator 22 can be ensured, and at the same time, the space for collecting dust in the first dust collection chamber 10aa can be made as large as possible, making it easier to collect dust.

[0053] The specific shape of the separating portion 21 is not limited, and may be, for example, a cone or a truncated cone.

[0054] In another embodiment of the present invention, there is provided a cleaning appliance 1000 comprising a main body and a dust cup unit 100 according to any embodiment of the present invention, wherein the dust cup unit 100 is mounted 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 according to any embodiment of the present invention, the base station being used to dock with the cleaning device 1000.

[0056] Specifically, the cleaning device 1000 is a cleaning appliance capable of realizing a cleaning function such as a vacuum cleaner.

[0057] The base station is a device that comes with the cleaning device 1000. The base station can be docked with the cleaning device 1000 and is used to collect dust and debris absorbed in 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 be used to charge the cleaning device 1000 by docking with the cleaning device 1000.

[0058] The dust cup unit 100 according to the embodiment of the present invention includes a cup body 10 and a dust separation unit 20. An airflow path is formed between the inlet 10b and the outlet 10c of the cup body 10. At least a portion of the fine dust separator 22 of the dust separation unit 20 is located in the airflow path, rotating the airflow entering through the inlet 10b and directing it along the airflow path. The fine dust separator 22 separates dust from the airflow, resulting in the dust cup unit 100 having a good dust separation effect. The separation section 21 of the dust separation unit 20 is located within the first dust collection chamber 10aa and is eccentrically installed relative to the first dust collection chamber 10aa. This disrupts the airflow within the first dust collection chamber 10aa, preventing dust in the first dust collection chamber 10aa from being re-floated by the rotating airflow, thereby further improving the dust separation effect. At the same time, because the external dimensions of separation section 21 gradually decrease from the end closest to fine dust separator 22 to the end farthest from fine dust separator 22, the turbulent flow effect at the end of separation section 21 closest to fine dust separator 22 can be enhanced, making it easier to collect dust that has fallen into first dust collection chamber 10aa and further improving the dust separation effect. As a result, the present invention does not create turbulence by adding beads, but by eccentrically installing them, which eliminates the problem of dust getting tangled in the beads, ensuring that dust cup unit 100 has a high dust separation effect and making dust cup unit 100 easier to clean and dispose of.

[0059] In a specific embodiment, the accommodation chamber 10a includes 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 overlap.

[0060] Of course, depending on the actual situation, they may not be coaxial, i.e., their centers do not overlap.

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

[0062] Specifically, the fine dust separator 22 is installed eccentrically with respect to the first dust collection chamber 10aa, while the separation unit 21 is installed coaxially with the first dust collection chamber 10aa, i.e., the centers of the two are on the same axis. In other words, the fine dust separator 22 is not coaxial with the separation unit 21, i.e., the centers of the two are not on the same axis. By offsetting the two relative to each other, 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 toward the top, thereby enhancing the separation effect between dust and the airflow.

[0063] In one embodiment, as shown in FIG. 2, the dust separation unit 20 includes a filtering unit 23 arranged 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 filtering unit 23 are located in the airflow path.

[0064] Specifically, only a portion of the filter unit 23 may be located in the airflow path, or the entire area of ​​the filter unit 23 may be located in the airflow path. The airflow that flows in through the intake port 10b rotates and passes through the filter unit 23 and the fine dust separator 22 in that order, and is then discharged through the exhaust port 10c.

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

[0066] By providing the filtration unit 23 on the outer periphery of the fine dust separator 22, it is possible to prevent a large amount of dust from entering the fine dust separator 22, and it is possible to prevent excessive dust from being mixed into the airflow discharged from the exhaust port 10c due to a decrease in the separation effect of the fine dust separator 22 caused by too much dust, thereby ensuring the dust separation effect.

[0067] In a specific embodiment, the filtering unit 23, the fine dust separator 22 and the receiving chamber 10a are all centered together, and the fine dust collector is eccentrically installed relative to the first dust collecting chamber 10aa.

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

[0069] In one embodiment, as shown in FIG. 2, the dust separation unit 20 includes a dust cover 24 located on the side of the filtration unit 23 away from the exhaust port 10c, 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 filter unit 23 and the first dust collection chamber 10aa, and can prevent dust from being stirred up again by the airflow in the first dust collection chamber 10aa, thereby improving the separation effect of dust in the airflow.

[0071] In addition, to make it easier for dust to fall into the first dust collection chamber 10aa by centrifugal force and gravity, there is a gap 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 cross-sectional dimensions of dustproof cover 24 gradually increase from the side farther from first dust collecting chamber 10aa to the side closer to first dust collecting chamber 10aa. This reduces the effect of dustproof cover 24 on dust falling into first dust collecting chamber 10aa, improves the blocking effect of dustproof cover 24 on dust inside first dust collecting chamber 10aa, and prevents dust inside first dust collecting chamber 10aa from flying up again.

[0073] 2, one end of the airflow guide member 221 close to the dust guide member 222 extends into the second guide passage 222a and is spaced apart from the sidewall of the second guide passage 222a, forming a vent 22a. The air intake 10b communicates with the exhaust port 10c and the second dust collecting chamber 21a via the vent 22a.

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

[0075] There are no particular limitations on the shapes of the first guide passage 221a and the second guide passage 222a, and for example, the first guide passage 221a is formed in a cylindrical shape so that the airflow can easily rotate within the first guide passage 221a.

[0076] As shown in FIGS. 2 and 3, the second guide passage 222a gradually narrows from the side farther from the fine dust collector toward the side closer to the fine dust collector.

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

[0078] The specific structural shape of the second guide passage 222a is not limited, and may be a cone or a truncated cone so that dust can easily fall into the second dust collecting chamber 21a.

[0079] The specific structural shape of the second dust collecting chamber 21a can be determined depending on the outer dimensions of the separating section 21, and may be, for example, a cone shape or a truncated cone shape.

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

[0081] In one embodiment, as shown in FIG. 2, one end of the dust guide member 222 close to the fine dust collector extends into the second dust collecting chamber 21a.

[0082] On the one hand, by making the length of the second guide passage 222a as long as possible without changing the overall dimensions of the dust cup unit 100, it is possible to prevent dust from being easily stirred up and re-moved by the airflow due to the second guide passage 222a being too short. On the other hand, it is possible to ensure the turbulent effect of the fine dust collector on the airflow in the first dust collection chamber 10aa without reducing the dimensions of the fine dust collector.

[0083] The fine dust collector may also be installed eccentrically with respect to the dust guide member 222. This ensures that the fine dust collector is installed eccentrically with respect to the first dust collection chamber 10aa, while also ensuring that the dust guide member 222 and the center of the storage chamber 10a are aligned. At the same time, the dust guide member 222 can also create turbulence in the second dust collection chamber 21a, preventing dust in the second dust collection chamber 21a from being stirred up again.

[0084] 2, the fine 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 disposed at a distance from the end face of the airflow guide member 221 that is closer to the exhaust port 10c, and a third guide passage 22b that connects the exhaust port 10c and the first guide passage 221a is formed at the distance.

[0085] Specifically, by providing the partition member 223, a third 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 guide passage 22b, thereby ensuring the cleanliness of the airflow flowing out of the exhaust port 10c.

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

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

[0088] 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 provided to cover the dust outlet in an openable and closable manner.

[0089] 2. Description of the Related Art Vacuum cleaners are common cleaning devices 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.

[0090] However, the dust cup device in the related art cannot separate some small particles of dust, which are discharged with the airflow, thereby affecting the service life of the motor and polluting the environment.

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

[0092] Specifically, the cup body 10 may be a hollow housing, such as a cylindrical or rectangular body. Materials for the cup body 10 include, but are not limited to, plastic and metal. The cup body 10 is formed with a first dust collection chamber 10aa and multiple second dust collection chambers 21a, with the multiple second dust collection chambers 21a 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 multiple second dust collection chambers 21a do not overlap with the center of the first dust collection chamber 10aa. For example, as shown in FIG. 5, four second dust collection chambers 21a may be provided, with the centers of the four second dust collection chambers 21a surrounding the center of the first dust collection chamber 10aa.

[0093] The cup body 10 can accommodate the filtering unit 23 and multiple dust guide members 222, with the inlets of the multiple dust guide members 222 communicating with the outlet of the filtering unit 23 and the outlet 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 in which there are four dust guide members 222 and second dust collection chambers 21a. The filtering unit 23 centrifuges the dust, causing some of the dust to centrifuge into the first dust collection chamber 10aa, while the remaining dust enters the dust guide member 222 along the outlet of the filtering unit 23, is centrifuged by the dust guide member 222, and then falls into the second dust collection chamber 21a. That is, the dust is sucked into the filtering unit 23, and the suction force causes the dust to undergo centrifugal motion in the filtering unit 23, with some of the heavier dust being centrifuged into the first dust collection chamber 10aa, and the remaining lighter dust being centrifuged along the filtering unit 23 to the dust guide member 222, and after being centrifuged within the dust guide member 222, each falls into one of 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 arranged 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 arranged close to the center of the cyclone separation. In this way, light dust 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 arranging 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 chamber 21a is improved.

[0095] As shown in FIG. 6, the filtering unit 23 can be configured in a regular or irregular shape, such as a cylindrical or conical shape. The filtering unit 23 is located within the cup body 10 and has a plurality of through-holes 23a arranged on the sidewall of the filtering unit 23 to form a filter structure. Dust inside the filtering unit 23 can enter the first dust collection chamber 10aa through the through-holes 23a. The filtering unit 23 can be made of materials including, but not limited to, plastic and metal. A metal filtering unit 23 generates less static electricity during operation than a plastic filtering unit 23, effectively reducing dust adhesion to the filtering unit 23 and preventing the through-holes 23a from becoming clogged with dust.

[0096] As shown in FIG. 5, multiple dust guide members 222 are adjacent to each other to form an annular body, and multiple second dust collection chambers 21a are adjacent to each other and fitted into the dust guide members 222. The annular body is spaced apart from the filter unit 23, forming a storage space 222b between the annular body and the filter unit 23, allowing dust to undergo centrifugal movement within the storage space 222b. The storage space 222b is connected to the first dust collection chamber 10aa via the through-holes 23a. The second dust collection chambers 21a and the dust guide members 222 may be molded integrally or separately. Each dust guide member 222 is connected to a corresponding second dust collection chamber 21a, and the second dust collection chamber 21a can store the dust in the dust guide members 222.

[0097] 7, the cup body 10 includes a dust box 11 and a bottom lid 12. The bottom lid 12 can be hingedly connected to the dust box 11 and is provided so as to be able to open and close on the dust box 11. When the bottom lid 12 is closed over the dust box 11, the first dust collection chamber 10aa is closed so that dust separated by the filtration unit 23 can be accommodated in the first dust collection chamber 10aa, and the second dust collection chamber 21a is closed so that dust separated by the dust guide member 222 can be accommodated in the second dust collection chamber 21a.

[0098] As shown in combination with Figure 8, an embodiment of the present invention further provides a cleaning appliance 1000. The above-mentioned dust cup unit 100 can be used in the cleaning appliance 1000, or the cleaning appliance 1000 comprises the above-mentioned dust cup unit 100.

[0099] The dust cup unit 100 and cleaning device according to the embodiment of the present invention are provided with a cup body 10, a filter unit 23, and a plurality of dust guide members 222, and are designed so that the cup body 10 is formed with a first dust collection chamber 10aa and a plurality of second dust collection chambers 21a. When the cleaning device 1000 sucks dust into the filter unit 23, the centrifugal action of the filter unit 23 causes larger dust particles to pass through the through holes 23a of the filter unit 23 and fall into the first dust collection chamber 10aa, while smaller dust particles enter the dust guide member 222 through the outlet of the filter unit 23. The centrifugal action of the dust guide member 222 then 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, dust is separated twice, and small dust particles are discharged with the airflow, which prevents environmental pollution and also prevents an impact on the service life of the cleaning device 1000, thereby improving the quality of the cleaning device 1000.

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

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

[0102] As shown in FIG. 7 , the dust cup unit 100 further includes a locking member 30 located at one end of the dust box 11 near the bottom cover 12. The locking member 30 is configured to lock the bottom cover 12 in place. That is, the locking member 30 is used to prevent the bottom cover 12 from opening due to gravity. For example, the locking member 30 can engage with the bottom cover 12, and the user can manually release the locking member 30. The locking member 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 locking member 30 can be determined according to actual circumstances and is not limited herein.

[0103] As shown in combination with FIG. 6, in some examples, the cup body 10 is formed with an air intake 10b, which is connected to the filtering unit 23. When the cleaning device 1000 is operating, the cleaning device 1000 can suck in dust-laden air. The dust-laden air enters the filtering unit 23 through the air intake 10b. After entering the filtering unit 23, the dust-laden air rotates, generating centrifugal force, which causes larger dust particles in the dust-laden air to pass through the through-holes 23a and fall into the second dust collection chamber 21a. The dust-laden air, along with the remaining smaller dust particles, enters the dust guide member 222. As the dust-laden air enters the dust guide member 222, centrifugal force is generated, causing the smaller dust particles to fall into each of the first dust collection chambers 10aa, and the remaining, almost clean air is discharged into the external environment.

[0104] 9, in some other examples, air intake 10b is provided facing filtration unit 23 and communicates with first dust collection chamber 10aa. That is, when cleaning device 1000 is operating, dust-laden air sucked into cleaning device 1000 enters first dust collection chamber 10aa, and centrifugal force is generated thereafter, causing larger dust particles in the dust-laden air to fall into first dust collection chamber 10aa, while the remaining dust passes through through-holes 23a and enters filtration unit 23. The centrifugal force causes the dust-laden air, along with the remaining smaller dust particles, to enter multiple dust guide members 222. The dust-laden air rotates and is separated by dust guide member 222, and the smaller dust particles fall into each of multiple second dust collection chambers 21a. In this way, the dust-containing air sucked in by the cleaning device 1000 is centrifuged multiple times, which prevents small dust particles from being discharged with the airflow and polluting the environment, while also preventing any impact on the service life of the cleaning device 1000, thereby improving the quality of the cleaning device 1000.

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

[0106] Specifically, the dust collection station 2000 is used to collect dust contained in the cleaning device 1000. The dust collection station 2000 includes a butting member 210 and a dust collection chamber 220. The butting member 210 may be funnel-shaped. The inlet of the butting member 210 is connected to the dust box 11. The size of the inlet of the butting member 210 is larger than the size of the bottom cover 12 of the cup body 10, allowing the bottom cover 12 to open within the butting member 210. The outlet of the butting member 210 is connected to the dust collection chamber 220, i.e., the dust collection chamber 220 communicates with the cup body 10 via the butting 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 tub. 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, 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 through the abutting member 210.

[0107] In some examples, after the cleaning device 1000 has completed its cleaning operation, the user places the cleaning device 1000 in the dust collection station 2000 and engages the butting 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 the plurality of first dust collection chambers 10aa are connected to the butting member 210, and the dust in the first dust collection chamber 10aa and the second dust collection chamber 21a can fall into the butting member 210.

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

[0109] In some examples, the locking member 30 can be opened when negative pressure exists in the dust collection chamber 220. That is, when a user needs to clean the cleaning device 1000, the user can turn on the suction motor 230. 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 dust from the first dust collection chamber 10aa and the second dust collection chamber 21a into the dust collection chamber 220.

[0110] In this way, in cleaning system 10000, dust accumulated in cleaning device 1000 can be cleaned by providing dust collection station 2000. Dust collection station 2000 can be connected to cleaning device 1000 by providing butting member 210. Butting member 210 is connected to dust collection chamber 220, which is connected to suction motor 230, and suction motor 230 sucks dust inside cleaning device 1000 into dust collection chamber 220 via butting member 210, thereby cleaning cleaning device 1000.
