[0040] See also Figure 1 An embodiment of the present application provides a dust cup assembly 100 , wherein the cleaning assembly includes a cavity 10 , a first separator 20 , and a plurality of second separators 30 .

[0041] Specifically, the cavity 10 can be a hollow shell such as a cylinder or a rectangular body, and the material of the cavity 10 includes but is not limited to plastic, metal, etc. The cavity 10 is formed with a first dust collecting chamber 11 and a plurality of second dust collecting chambers 12, and the plurality of second dust collecting chambers 12 are located in the first dust collecting chamber 11. The first dust collecting chamber 11 and the second dust collecting chamber 12 are used to collect garbage, and the centers of the plurality of second dust collecting chambers 12 do not coincide with the center of the first dust collecting chamber 11. For example, please combine Figure 2 The second dust collecting chambers 12 may include four, and the centers of the four second dust collecting chambers 12 are arranged around the center of the first dust collecting chamber 11.

[0042] The cavity 10 can accommodate a first separator 20 and a plurality of second separators 30, the inlets of the plurality of second separators 30 are connected to the outlet of the first separator 20, and the outlet of each second separator 30 is connected to a second dust collecting chamber 12, that is, the number of the second separators 30 is the same as the number of the second dust collecting chambers 12, and the second separators 30 and the second dust collecting chambers 12 of the present application are illustrated in four examples. The first separator 20 is configured to centrifuge the garbage to centrifuge part of the garbage into the first dust collecting chamber 11, and the remaining garbage enters the second separator 30 along the outlet of the first separator 20, and falls into the second dust collecting chamber 12 after being centrifuged by the second separator 30, that is, the garbage is sucked into the first separator 20, and under the action of suction, the garbage performs centrifugal motion in the first separator 20, and some of the heavier garbage is centrifuged into the first dust collecting chamber 11, and the remaining lighter garbage is centrifuged along the first separator 20 to the second separator 30, and falls into the plurality of second dust collecting chambers 12 respectively after being centrifuged in the second separator 30.

[0043] It should be noted that the center of the first dust collecting chamber 11 is the center of the cavity 10, that is, the centers of the multiple second dust collecting chambers 12 are arranged around the center of the cavity 10, and the outlet of each second separator 30 is connected to a second dust collecting chamber 12, so that the multiple second separators 30 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 second separators 30, and thus be received by the multiple second dust collecting chambers 12. The centers of the multiple second dust collecting chambers 12 are arranged around the center of the first dust collecting chamber 11, which improves the dust collection efficiency of the second dust collecting chambers 12.

[0044] Please combine Figure 3 The first separator 20 can be arranged in a regular or irregular shape such as a cylinder or a cone. The first separator 20 is located in the cavity 10. The first separator 20 is provided with a plurality of through holes 21. The plurality of through holes 21 are distributed on the side wall of the first separator 20 and form a filter structure. The garbage in the first separator 20 can enter the first dust collecting chamber 11 through the through holes 21. The material of the first separator 20 includes but is not limited to plastic, metal, etc. Compared with the plastic first separator 20, the metal first separator 20 generates less static electricity during operation, which can effectively reduce the dust attached to the first separator 20 and prevent the through holes 21 from being blocked by the attached dust.

[0045] Please combine Figure 2 , multiple second separators 30 are adjacent to form an annular body 31, multiple second dust collecting chambers 12 are adjacent, the second dust collecting chamber 12 is arranged in coordination with the second separator 30, the annular body 31 is arranged at intervals from the first separator 20, and a receiving space 32 is formed between the annular body 31 and the first separator 20, and garbage can be centrifugally moved in the receiving space 32, and the receiving space 32 is connected to the first dust collecting chamber 11 through the through hole 21. It should be noted that the second dust collecting chamber 12 and the second separator 30 can be an integrally formed structure or a split-formed structure, and each second separator 30 is connected to a corresponding second dust collecting chamber 12, and the second dust collecting chamber 12 can accommodate the garbage in the second separator 30.

[0046] See also Figure 4 The cavity 10 includes a dust barrel 13 and a bottom cover 14. The bottom cover 14 can be hinged to the dust barrel 13. The bottom cover 14 can be opened and closed on the dust barrel 13. When the bottom cover 14 is covered on the dust barrel 13, the first dust collecting chamber 11 is closed so that the first dust collecting chamber 11 can accommodate the garbage separated by the first separator 20, and the second dust collecting chamber 12 is closed so that the second dust collecting chamber 12 can accommodate the garbage separated by the second separator 30.

[0047] Please combine Figure 5The embodiment of the present application also provides a cleaning device 1000, and 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.

[0048] In the dust cup assembly 100 and the cleaning device of the embodiment of the present application, a cavity 10, a first separator 20 and a plurality of second separators 30 are provided, and the cavity 10 forms a first dust collecting chamber 11 and a plurality of second dust collecting chambers 12. When the cleaning device 1000 sucks garbage into the first separator 20, due to the centrifugal action of the first separator 20, dust with larger particles passes through the through hole 21 of the first separator 20 and falls into the first dust collecting chamber 11, and dust with smaller particles enters the second separator 30 through the outlet of the first separator 20, and then due to the centrifugal action of the second separator 30, dust with smaller particles falls into the plurality of second dust collecting chambers 12. In this way, the garbage is separated twice by providing the first separator 20 and the second separator 30, thereby avoiding dust with smaller particles from being discharged with the airflow to pollute the environment, and also avoiding affecting the service life of the cleaning device 1000, thereby improving the quality of the cleaning device 1000.

[0049] The cleaning device 1000 is used to clean up garbage. For example, the cleaning device 1000 may be a handheld vacuum cleaner or other device used to clean dust. The embodiment of the present application is described using a handheld vacuum cleaner as an example.

[0050] 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.

[0051] Please combine Figure 4 The dust cup assembly 100 further includes a locker 40, which is located at one end of the dust cylinder 13 close to the bottom cover 14. The locker 40 is configured to limit the bottom cover 14, that is, the locker 40 is used to prevent the bottom cover 14 from opening under the action of gravity. For example, the locker 40 can be engaged with the bottom cover 14, and the user can manually unlock the locker 40. The locker 40 can also be magnetically attracted to the bottom cover 14. When the bottom cover 14 is subjected to other forces to overcome the magnetic attraction, the bottom cover 14 is opened. The specific setting of the locker 40 can be configured according to actual conditions and is not limited here.

[0052] Please combine Figure 3In some examples, an air inlet 15 is formed on the cavity 10, and the air inlet 15 is connected to the first separator 20. When the cleaning device 1000 is working, the cleaning device 1000 can inhale dusty air, and the dusty air enters the first separator 20 through the air inlet 15. After entering the first separator 20, the dusty air rotates to generate centrifugal force, and the dust with larger particle size in the dusty air passes through the through hole 21 under the action of the centrifugal force and falls into the second dust collecting chamber 12. The dusty air carries the remaining dust with smaller particle size into the second separator 30, and the dusty air enters the second separator 30 to generate centrifugal force, so that the dust with smaller particle size falls into multiple first dust collecting chambers 11 respectively, and the remaining nearly clean air is output to the external environment.

[0053] Please combine Figure 6 In other examples, the air inlet 15 is arranged toward the first separator 20, and the air inlet 15 is connected to the first dust collecting chamber 11, that is, when the cleaning device 1000 is working, the dust-laden air sucked by the cleaning device 1000 enters the first dust collecting chamber 11 and rotates to generate centrifugal force, and the dust with larger particle size in the dust-laden air falls into the first dust collecting chamber 11, and the remaining dust passes through the through hole 21 and enters the first separator 20. Under the action of centrifugal force, the dust-laden air carries the remaining dust with smaller particle size into multiple second separators 30, and the dust-laden air rotates in the second separators 30 for separation, so that the dust with smaller particle size falls into multiple second dust collecting chambers 12 respectively. In this way, the dust-laden air sucked by the cleaning device 1000 is centrifugally separated multiple times, which prevents the dust with smaller particle size from being discharged with the airflow and polluting the environment, and also avoids affecting the service life of the cleaning device 1000, thereby improving the quality of the cleaning device 1000.

[0054] See also Figure 5 The embodiment of the present application also provides a cleaning system 10000 , and the cleaning system 10000 includes a dust collection station 2000 and a cleaning device 1000 .

[0055] Specifically, the dust collecting station 2000 is used to collect dust contained in the cleaning device 1000. The dust collecting station 2000 includes a docking piece 210 and a dust collecting chamber 220. The docking piece 210 may be funnel-shaped. The inlet of the docking piece 210 is connected to the dust cylinder 13. The inlet size of the docking piece 210 is larger than the size of the bottom cover 14 on the cavity 10, so that the bottom cover 14 can be opened in the docking piece 210. The outlet of the docking piece 210 is connected to the dust collecting chamber 220, that is, the dust collecting chamber 220 is connected to the cavity 10 through the docking piece 210. The dust collecting chamber 220 may be a device for collecting dust, such as a dust collecting bag, a dust collecting cup, or a dust collecting barrel. The dust collecting chamber 220 may allow air to pass through and prevent dust from passing through. The dust collecting chamber 220 is used to contain dust. The dust stored in the first dust collecting chamber 11 and the second dust collecting chamber 12 may fall into the dust collecting chamber 220 through the docking piece 210.

[0056] In some examples, after the cleaning device 1000 completes the cleaning work, the user puts the cleaning device 1000 into the dust collection station 2000, and the docking piece 210 is engaged with the dust cylinder 13 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 40, so that the bottom cover 14 is opened, the second dust collection chamber 12 and the plurality of first dust collection chambers 11 are connected to the docking piece 210, and the dust in the first dust collection chamber 11 and the second dust collection chamber 12 can fall into the docking piece 210.

[0057] 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 11 and the second dust collecting chamber 12 is sucked into the dust collecting chamber 220 through the docking piece 210, thereby cleaning the first dust collecting chamber 11 and the second dust collecting chamber 12.

[0058] In some examples, the lock 40 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 40 is unlocked, the bottom cover 14 is opened, and the dust in the first dust collecting chamber 11 and the second dust collecting chamber 12 is sucked into the dust collecting chamber 220.

[0059] 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, and 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, and 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.
