Further, the present application provides various examples of specific processes and materials, but those of ordinary skill in the art may appreciate that it is possible to apply other processes and / or other materials.

[0037] Referring to FIGS. 1 and 2, an embodiment of the present application provides a dust cup assembly 100 comprising a cup body 10 and a dust separation assembly 20. The cup body 10 has accommodation chamber 10a, air inlet 10b and air outlet 10c. An airflow path is formed between the air inlet 10b and the air outlet 10c. The accommodation chamber 10a comprises a first dust collection chamber 10aa which is in communication with the air inlet 10b, and located on a bottom side of the air inlet 10b.

[0038] The dust separation assembly 20 comprises a fine dust separator 22 and a separation portion 21. At least a portion of the fine dust separator 22 is located in the airflow path such that the airflow entering from the air inlet 10b flows along the airflow path by rotation. The separation portion 21 is located in the first dust collection chamber 10aa and is disposed eccentrically with respect to the first dust collection chamber 10aa.The separation portion 21 is tapered in a direction from an end near the fine dust separator 22 to an end far from the fine dust separator 22.

[0039] Specifically, the dust separation assembly 20 is arranged in the accommodation chamber 10a, and is configured for separating dust from the airflow. The airflow path from air inlet 10b to air outlet 10c passes through at least part of fine dust separator 22, and the airflow along the airflow path moves rotationally.

[0040] The specific structure of the separation portion 21 is not limited. For example, referring to FIG. 2, the separation portion 21 is a fine dust collector having a second dust collection chamber 21a in communication with the fine dust separator 22.

[0041] Specifically, the second dust collection chamber 21a is configured to collect the fine dust in the airflow flowing along the airflow path. The fine dust collector can disturb the airflow movement in the first dust collection chamber 10aa while collecting the fine dust.

[0042] The center of the fine dust separator 22 may be aligned with the center of the accommodation chamber 10a to prevent the dust separation assembly 20 from disturbing the rotational movement of the airflow along the airflow path. Of course, according to the actual situation, the fine dust separator can also be arranged eccentrically with respect to the accommodation chamber.

[0043] A portion of the fine dust separator 22 may be located in the airflow path, or the entire fine dust separator may be located in the airflow path.

[0044] In addition, the specific structure of the fine dust separator 22 may be constructed according to the actual situation.

[0045] As an example, referring to FIGS. 2 and 3, the fine dust separator 22 comprises an airflow guide 221 and a dust guide 222. The airflow guide 221 has a first guide channel 221a, and the dust guide 222 has a second guide channel 222a. The airflow guide 221 is located at an end of the dust guide 222 away from the fine dust collector. The first guide channel 221a is in communication with the air outlet 10c, and the second guide channel 222a is in communication with the second dust collection chamber 21a.

[0046] It should be noted that the position of the air inlet 10b on the cup body 10 is arranged in such a way that the airflow rotates about the central axis of the accommodation chamber 10a after entering the accommodation chamber 10a (for example, the air inlet 10b is provided on the sidewall of the cup body 10).

[0047] The operation principle of the dust cup assembly 100 of the present application is described by taking FIG. 2 as an example. When the airflow carrying dust flows from the air inlet 10b into the accommodation chamber 10a, it rotates along the side wall of the accommodation chamber 10a. Under the action of centrifugal force and self-gravity, part of the dust (mainly coarse dust with relatively coarse particles) in the airflow is thrown to the side wall of the accommodation chamber 10a, rotates along the side wall of the accommodation chamber 10a, and falls into the first dust collection chamber 10aa. Another part of the dust (dust with relatively fine particles) will enter into the fine dust separator 22 along the airflow path. In this way, part of the dust can be separated from the airflow. Further, the airflow entering into the fine dust separator 22 continues to rotate along the airflow path to rotate along the sidewall of the first guide channel 221a, and exit from the air outlet 10c. Under the action of gravity and centrifugal force, the dust entering into the fine dust separator 22 will rotate along the side wall of the second guide channel 222a and move toward the bottom side, so as to be collected in the second dust collection chamber 21a. As such, the airflow and the dust entering into the fine dust separator 22 can be moved in opposite directions, so that the separation of the dust from the airflow can be further realized.

[0048] The separation portion 21 is arranged eccentrically with respect to the first dust collection chamber 10aa, which means that the centers of the separation portion and the first dust collection chamber are incoincident, such as the central axes of the separation portion and the first dust collection chamber are incoincident.

[0049] Driven by the rotating airflow flowing along the airflow path, an airflow moving toward the top side while rotating is easily formed in the first dust collection chamber 10aa. Therefore, by arranging the separation portion 21 eccentrically with respect to the first dust collection chamber 10aa, the rotational movement of the airflow in the first dust collection chamber 10aa can be hindered to disrupt the flow of the airflow, so as to prevent the dust collected in the first dust collection chamber 10aa from being raised again.

[0050] It should be noted that the region of the dust separation assembly 20 of the present application located in the first dust collection chamber 10aa is arranged eccentrically with respect to the first dust collection chamber 10aa for the purpose of achieving the effect of disturbing flow. If other structures are added to the outside of the separation portion 21 in such a way that the center of the integral structure coincides with the center of the first dust collection chamber 10aa, the effect of disturbing flow cannot be achieved.

[0051] In addition, the separation portion 21 of the present application does not directly hinder the airflow movement by the structure itself. Since the center of the separation portion 21 is incoincident with the center of the first dust collection chamber 10aa (in fact, the center of the rotational movement of the airflow), the upward rotational movement of the airflow is disrupted, so that the dust in the first dust collection chamber 10aa is prevented from being raised again, and the dust collection effect can be improved.

[0052] Due to the separation portion 21 tapered from an end adjacent to the fine dust separator 22 to an end away from the fine dust separator 22, it is possible to ensure a flow disturbing effect at the end of the separation portion adjacent to the fine dust separator 22, and at the same time, it is possible to increase the space for dust collection in the first dust collection chamber 10aa as much as possible to facilitate the dust collection.

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

[0054] Another embodiment of the present application provides a cleaning device 1000 comprising a body and a dust cup assembly 100 as described in any embodiment of the present application, the dust cup assembly 100 is arranged on the body.

[0055] Yet another embodiment of the present application provides a cleaning system 10000 comprising a base station and a cleaning device 1000 according to any embodiment of the present application, the base station is configured for docking with the cleaning device 1000.

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

[0057] The base station is a device cooperating with the cleaning device 1000. The base station can be docked with the cleaning device 1000 for collecting the dust and the trash received in the dust cup assembly 100. Of course, according to the actual situation, the base station can also have other functions. For example, the base station can also be used to charge the cleaning device 1000 by docking with the cleaning device 1000.

[0058] The dust cup assembly 100 of the embodiment of the present application comprises the cup body 10 and the dust separation assembly 20, and the airflow path is formed between the air inlet 10b and the air outlet 10c of the cup body 10. On one hand, at least a portion of the fine dust separator 22 of the dust separation assembly 20 is located on the airflow path such that the airflow entering from the air inlet 10b flows along the airflow path by rotation. Thus, by providing the fine dust separator 22, the dust can be separated from the airflow, so that the dust cup assembly 100 has a better dust separation effect. On the other hand, the separation portion 21 of the dust separation assembly 20 is located in the first dust collection chamber 10aa and is arranged eccentrically with respect to the first dust collection chamber 10aa, so that the flow of the airflow in the first dust collection chamber 10aa can be disturbed, and the dust in the first dust collection chamber 10aa can be prevented from being raised again by the rotating airflow, and thus the effect of dust separation can be further improved. Further, since the separation portion 21 is tapered from the end adjacent to the fine dust separator 22 to the end away from the fine dust separator 22, the effect of disturbing of the flow at the end of the separation portion 21 adjacent to the fine dust separator 22 can be improved, and dust falling in the first dust collection chamber 10aa can be collected, thereby further improving the effect of dust separation. Therefore, the present application is to disturb the flow by the eccentric arrangement, instead of by adding ribs, and there will be no problem of accumulating dust on the ribs, so that the dust cup assembly 100 can be easily cleaned while ensuring that the dust cup assembly 100 has a good dust separation effect.

[0059] In a particular embodiment, the accommodation chamber 10a comprises a first dust collection chamber 10aa and a separation chamber for arranging the airflow path, the first dust collection chamber 10aa and the separation chamber are coaxial, that is, the center of the first dust collection chamber 10aa coincides with and the center of the separation chamber.

[0060] Of course, according to the actual situation, the first dust collection chamber and the separation chamber can also be of different axes, that is, the center of the first dust collection chamber is incoincident with and the center of the separation chamber.

[0061] In one embodiment, referring to FIG. 2, the fine dust separator 22 is arranged coaxially with the first dust collection chamber 10aa.

[0062] Specifically, the fine dust separator 22 is arranged eccentrically with respect to the first dust collection chamber 10aa, while the separation portion 21 is arranged coaxially with the first dust collection chamber 10aa, i.e., the centers of both are on the same axis. That is, the fine dust separator 22 and separation portion 21 are not coaxial, that is, the centers of the fine dust separator and separation portion are not on the same axis. In this way, by arranging the fine dust separator and separation portion which are staggered, it is possible to further prevent the airflow in the first dust collection chamber 10aa from rotating towards the top side about the dust separation assembly 20, thereby enhancing the effect of separating the dust from the airflow.

[0063] In one embodiment, referring to FIG. 2, the dust separation assembly 20 comprises a filter assembly 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 filter assembly 23 are located in the airflow path.

[0064] Specifically, the filter assembly 23 may be partially located in airflow path, or may be completely located in airflow path. The airflow entering from the air inlet 10b passes through the filter assembly 23 and the fine dust separator 22 while rotating, and then is discharged through the air outlet 10c.

[0065] The filter assembly 23 (such as a filter hood) is configured for separating the dust from the airflow flowing along the airflow path. The filter assembly 23 can be configured to block hairs, fibers, coarse dust, etc., and the aperture size of the filter assembly determines the size of the dust that can enter into the fine dust separator 22 through the filter assembly 23.

[0066] By providing the filter assembly 23 on the outer periphery of the fine dust separator 22, it is possible to prevent excessive dust from entering into the fine dust separator 22, so as to prevent excessive dust from reducing the separation effect of the fine dust separator 22 and avoid excessive dust being comprised in the airflow discharged from the air outlet 10c, and thus the effect of dust separation can be ensured.

[0067] In one embodiment, the centers of the filter assembly 23, the fine dust separator 22 and the accommodation chamber 10a coincide with each other, and the fine dust collector is arranged eccentrically with respect to the first dust collection chamber 10aa.

[0068] In one embodiment, the fine dust collector is located on the bottom side of dust guide 222, the airflow guide 221 is located on the top side of dust guide 222, and air outlet 10c is located on the top side of airflow guide 221.

[0069] In one embodiment, referring to FIG. 2, the dust separation assembly 20 comprises a dust shield 24 located on the side of the filter assembly 23 away from the air outlet 10c. The first dust collection chamber 10aa is defined between the dust shield 24 and the bottom wall of the cup body 10.

[0070] Specifically, the dust shield 24 is located between the filter assembly 23 and the first dust collection chamber 10aa, and can prevent dust from being raised again by the airflow of the first dust collection chamber 10aa, thereby improving the effect of separating the dust in the airflow.

[0071] It should be noted that there is a space between the dust shield 24 and the side wall of the cup body 10, so as to allow the dust to fall into the first dust collection chamber 10aa under the action of centrifugal force and gravity. The specific structure is not limited.

[0072] For example, the cross-sectional area of the dust shield 24 gradually increases from a side away from the first dust collection chamber 10aa to a side adjacent to the first dust collection chamber 10aa. As such, the influence of the dust shield 24 on the dust falling into the first dust collection chamber 10aa can be reduced, the blocking effect of the dust shield 24 on the dust in the first dust collection chamber 10aa can be improved, and the dust in the first dust collection chamber 10aa can be prevented from being raised again.

[0073] In one embodiment, referring to FIG. 2, an end of the airflow guide 221 adjacent 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 vent 22a at the spacing. The air inlet 10b is in communication with the air outlet 10c and the second dust collection chamber 21a through the air vent 22a.

[0074] Specifically, the airflow flowing through the filter assembly 23 rotates around the outer wall surface of the airflow guide 221 and moves to the bottom side to pass through the air vent 22a. The airflow then enters into the first guide channel 221a from the bottom side, and moves to the air outlet 10c while rotating along the side wall of the first guide channel 221a. After the airflow rotates around the outer wall surface of the airflow guide 221 and passes through the air vent 22a, the dust (such as fine dust) carried in the airflow rotates and moves along the side wall of the second guide channel 222a to the bottom side under the action of centrifugal force and gravity, so as to move into the second dust collection chamber 21a.

[0075] 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 in order to facilitate the rotational movement of the airflow within the first guide channel 221a.

[0076] As an example, referring to FIGS. 2 and 3, the second guide channel 222a is convergent in a direction from the side away from the fine dust collector towards the side adjacent to the fine dust collector.

[0077] That is, by gradually reducing the cross-sectional area of the second guide channel 222a, the dust can be intensively moved into the second dust collection chamber 21a, and the cross-sectional area of a joint between the second guide channel 222a and the second dust collection chamber 21a can be reduced, so that dust in the second dust collection chamber 21a can be prevented from being raised again, and the effect of separating the dust from the airflow can be improved.

[0078] The second guide channel 222a may be of a conical shape or a frustoconical shape, and can facilitate dust to fall into the second dust collection chamber 21a.

[0079] The specific shape of the second dust collection chamber 21a can be determined according to the shape and dimension of the separation portion 21, for example, can be a conical shape or a frustoconical shape.

[0080] For example, the second dust collection chamber 21a is flared in a direction from the side away from the dust guide 222 towards the side adjacent to the dust guide 222.

[0081] In one embodiment, referring to FIG. 2, the end of the dust guide 222 adjacent to the fine dust collector extends into the second dust collection chamber 21a.

[0082] On the one hand, the length of the second guide channel 222a can be increased as much as possible while the overall size of the dust cup assembly 100 remains unchanged, so as to prevent dust from easily rising and moving again with the airflow due to short length of the second guide channel 222a. On the other hand, the size of the fine dust collector is not reduced, and the disturbing effect of the fine dust collector on the airflow in the first dust collection chamber 10aa can be ensured.

[0083] In addition, the fine dust collector may be arranged eccentrically with respect to the dust guide 222. In this way, the center of the dust guide 222 and the center of the accommodation chamber 10a can be kept coincident while ensuring that the fine dust collector is arranged eccentrically with respect to the first dust collection chamber 10aa. Furthermore, the dust guide 222 can disturb the airflow in the second dust collection chamber 21a, and further prevent the dust in the second dust collection chamber 21a from being raised again.

[0103] Referring to FIG. 6, in some examples, an air inlet 10b is formed on a cup body 10. The air inlet 10b is connected to the filter assembly 23. During operation of the cleaning device 1000, the dusty air will be sucked into the cleaning device 1000, passes through the air inlet 10b and enters into the filter assembly 23. After the dusty air enters the filter assembly 23, it rotates and generates a centrifugal force. Under the action of the centrifugal force, the dust with larger particle size in the dusty air passes through the through holes 23a and falls into the second dust collection chambers 21a. The dusty air carrying the remaining dust with small particle size enters into the dust guides 222, and generates a centrifugal force, so that the dust with small particle size falls into a plurality of first dust collection chambers 10aa. Then nearly clean air is output to the external environment.

[0104] Referring to FIG. 9, in other examples, the air inlet 10b faces towards the filter assembly 23. The air inlet 10b is in communication with the first dust collection chamber 10aa, that is, during the operation of the cleaning device 1000, the dusty air sucked into the cleaning device 1000 enters the first dust collection chamber 10aa and rotates to generate a centrifugal force, and dust with larger particle size in the dusty air falls into the first dust collection chamber 10aa. The remaining dust enters the filter assembly 23 through the through holes 23a. Under the action of the centrifugal force, the dusty air carrying the remaining dust with a small particle size enters into the plurality of dust guides 222. The dusty air rotates in the dust guides 222 to separate the dust, so that the dust with smaller particle size falls into the plurality of second dust collection chambers 21a. In this way, the dusty air sucked into the cleaning device 1000 has undergone multiple centrifugal separations, which prevents the dust with small particle size from discharging with the airflow and polluting the environment, and also avoids affecting the service life of the cleaning device 1000, and thus the quality of the cleaning device 1000 is improved.
