DETAILED DESCRIPTION

[0038] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0039] 1 , a dust cup assembly 1000 is provided in accordance with an embodiment of the first aspect of the present application. The dust cup assembly 1000 includes a housing 100 and a cylinder. The cylinder is a cylindrical structure and includes a coarse ash separator 200 and a fine ash collector 300. Specifically, as shown in FIG1 , the housing 100 is provided with a cavity 110, an air inlet 130, and an air outlet 120. The air inlet 130 is connected to the cavity 110. The coarse ash separator 200 is provided in the cavity 110. A filter cavity 211 connected to the air outlet 120 is provided in the coarse ash separator 200. A filter hole 221 is provided on the side wall of the coarse ash separator 200. The filter hole 221 connects the filter cavity 211 with the cavity 110. It should be noted that the coarse ash separator 200 is mainly used to filter large clumps of dust and garbage to achieve coarse filtration.

[0040] As shown in Figure 1 , the fine ash collector 300 is disposed within the cavity 110 and is located below the coarse ash separator 200. The fine ash collector 300 comprises a cylindrical body 310 and an ash pressing portion 320, which are interconnected. The cylindrical body 310 is a hollow cylindrical structure, and is provided with a dust collecting chamber 311, which is connected to the filter chamber 211. The ash pressing portion 320 is an annular structure, sleeved around the outer circumference of the cylindrical body 310. The outer diameter of the ash pressing portion 320 is larger than that of the cylindrical body 310. Alternatively, the maximum width of the ash pressing portion 320 is larger than the maximum width of the cylindrical body 310. Furthermore, the outer diameter of the coarse ash separator 200 gradually decreases from top to bottom, or alternatively, the width of the coarse ash separator 200 gradually decreases from top to bottom. Furthermore, the maximum outer diameter of the ash pressing portion 320 is smaller than the minimum outer diameter of the coarse ash separator 200. Alternatively, it can be understood that the maximum width of the ash pressing portion 320 is smaller than the minimum width of the coarse ash separator 200. The coarse ash separator 200 may have a horizontal cross-section that is circular, elliptical, or racetrack-shaped, and the ash pressing portion 320 may have a horizontal cross-section that is circular, elliptical, or racetrack-shaped.

[0041] Specifically, when the dust cup assembly 1000 is working, the external airflow first enters the cavity 110 of the shell 100 from the air inlet 130, and the large clumps of dust and garbage in the airflow are coarsely filtered by the filter holes 221 of the coarse ash separator 200. Then, the cleaner airflow enters the filter cavity 211, and the fine dust and garbage in the filter cavity 211 are thrown into the dust collecting cavity 311 of the fine ash collector 300. Finally, the airflow leaves the filter cavity 211 and flows out of the shell 100 from the air outlet 120. By making changes to the traditional filtering structure, specifically, by setting up a coarse ash separator 200 and a fine ash collector 300 to filter dust and garbage, only the filter hole 221 of the coarse ash separator 200 will generate suction, and the fine ash collector 300 will not generate suction. Even if hair is wrapped around the fine ash collector 300, it will not block the filter hole 221. It can also be understood that the fine ash collector 300 is used to wrap most of the hair, which can reduce the hair wrapped around the outside of the coarse ash separator 200. In addition, when the airflow swirls in the cavity 110, the ash pressing part 320 can also block part of the hair. The hair is lifted upward and blocked in the space between the ash pressing portion 320 and the cylindrical portion 310, preventing the hair from moving upward to the filter holes 221 and coming into contact with the filter holes 221. Furthermore, even if the hair becomes entangled around the outer periphery of the coarse ash separator 200, the outer diameter of the coarse ash separator 200 gradually decreases from top to bottom, providing weak support for the hair. This prevents further tension on the hair and hinders its entanglement. Under the action of gravity, the hair gradually loosens and falls to the bottom of the housing 100, alleviating the problem of hair clogging the filter holes 221 and ensuring the fan's normal dust collection capacity. Furthermore, the maximum outer diameter of the ash pressing portion 320 is smaller than the minimum outer diameter of the coarse ash separator 200. This prevents hair from being blocked by the coarse ash separator 200 as it falls downward, allowing the hair to fall smoothly to the bottom of the cavity 110.

[0042] It should also be noted that, during use, the machine can be stopped to stop the airflow in the cavity 110 from swirling, thereby accelerating the speed at which the hair falls downward.

[0043] It can be understood that, as shown in Figure 1, in some embodiments, the shell 100 is also provided with a locking structure 140 and a rotating structure 150, and the dust cup assembly 1000 includes a bottom cover 500, one end of the bottom cover 500 is rotatably connected to the rotating structure 150, and the other end of the bottom cover 500 is buckled with the locking structure 140. The locking structure 140 can lock or loosen the bottom cover 500, and the bottom cover 500 can open or close the cavity 110 of the shell 100. When it is necessary to clean the garbage in the dust cup assembly 1000, the bottom cover 500 can be opened.

[0044] It can be understood that the embodiment of the present application also provides a vacuum cleaner, which includes the dust cup assembly 1000 of the above embodiment. The embodiment of the present application also provides a cleaning device, which includes the vacuum cleaner and the dust collection base station 2000 of the above embodiment. The dust collection base station 2000 is used to collect garbage in the shell 100, and the dust collection base station 2000 has a dust collection chamber 2100.

[0045] It should be noted that after using the cleaning device, a certain amount of dust and garbage will accumulate in the dust cup assembly 1000. Since there are many parts inside the dust cup assembly 1000, it is relatively troublesome to manually open and clean the interior. In this embodiment, after the dust collection base station 2000 is equipped, the dust cup assembly 1000 can be removed and installed on the dust collection base station 2000. Then, the bottom cover 500 of the dust cup assembly 1000 is opened, so that the cavity 110 of the shell 100 is connected to the dust collection chamber 2100 of the dust collection base station 2000. The fan in the dust collection base station 2000 can generate suction to suck out all the garbage in the dust cup assembly 1000. Specifically, as shown in Figure 4, the garbage moves downward in the direction of the arrow, from the cavity 110 of the shell 100 to the dust collection chamber 2100 of the dust collection base station 2000, thereby achieving the effect of automatically cleaning the dust cup assembly 1000. The operation is convenient and can improve the user experience. In addition, the dust cup assembly 1000 of this embodiment has optimized its structure so that hair is not easily entangled outside the coarse ash separator 200, and the dust collecting base station 2000 can suck out the hair more easily, thereby improving the user experience of the dust collecting base station 2000.

[0046] It should also be noted that, as shown in Figure 1, the above-mentioned dust collecting chamber 311 is defined between the bottom cover 500 and the barrel portion 310. After opening the bottom cover 500, the dust collecting chamber 311 can be opened, and the dust and garbage in the dust collecting chamber 311 can fall directly.

[0047] It should also be noted that the dust cup assembly 1000 of this embodiment can also be used in a cleaning device without a dust collection base station 2000. Specifically, when the dust cup assembly 1000 needs to be cleaned, the bottom cover 500 of the dust cup assembly 1000 can be opened, and the dust and garbage in the shell 100 will fall directly due to gravity. Since the dust cup assembly 1000 of this embodiment has optimized its structure, hair is not easily entangled outside the coarse ash separator 200. After opening the bottom cover 500, the hair in the shell 100 can fall smoothly due to gravity, which makes it easy to remove large clumps of garbage in the shell 100.

[0048] It can be understood that, referring to Figures 1 and 4, in some embodiments, the outer diameter of the ash pressing portion 320 gradually decreases from top to bottom, or, it can also be understood that the width of the ash pressing portion 320 gradually decreases from top to bottom. When the hair is wrapped around the outer periphery of the ash pressing portion 320, the support of the hair by the ash pressing portion 320 is weak, which can prevent the hair from being further tensioned. Under the action of gravity, the hair will gradually loosen from the ash pressing portion 320 and fall down.

[0049] It can be understood that, as shown in Figure 4, according to some embodiments of the present application, the fine ash collector 300 includes a rib portion 330, which is connected to the barrel portion 310, and the rib portion 330 is located between the barrel portion 310 and the ash pressing portion 320. The rib portion 330 is arranged along the radial direction of the barrel portion 310, and the width of the rib portion 330 is relatively small. By setting the rib portion 330, the contact area between the hair and the barrel portion 310 can be reduced. The rib portion 330 has a protruding structure, which is more irregular than the barrel portion 310 and has no support for the hair, making it difficult for the hair to be entangled around the outer periphery of the barrel portion 310, making it easier to clean the garbage inside the shell 100. Furthermore, in some embodiments, as shown in FIG4 , the distance from the side edge of the rib portion 330 to the barrel portion 310 along the horizontal direction gradually decreases from top to bottom. This can also be understood as the side edge of the rib portion 330 being a beveled or curved edge. When the side edge of the rib portion 330 is a beveled edge, the beveled edge can include multiple beveled segments, and the slopes of the multiple beveled segments can be the same or different, as long as the distance from the side edge of the rib portion 330 to the barrel portion 310 along the horizontal direction gradually decreases from top to bottom. It should be noted that this arrangement can reduce the support provided to the hair when it is wrapped around the rib portion 330 and the barrel portion 310, preventing further tension on the hair. Under the action of gravity, the hair can gradually loosen and fall to the bottom of the cavity 110.

[0050] It should be noted that the rib portion 330 may include one or more ribs, and the multiple ribs may be arranged along the circumference of the barrel portion 310 to improve the anti-hair entanglement effect.

[0051] As can be understood, as shown in FIG4 , according to some embodiments of the present application, the rib portion 330 includes a first rib 331 and a second rib 332. The first rib 331 and the second rib 332 are arranged opposite each other, that is, the first rib 331 is located on one side of the barrel portion 310, and the second rib 332 is located on the other side of the barrel portion 310. This arrangement can further prevent hair from being entangled around the outer periphery of the barrel portion 310. It should be noted that, considering that the first rib 331 and the second rib 332 block a portion of airflow and dust and debris, affecting the distribution of dust and debris, the first rib 331 can be made longer in the horizontal direction, while the second rib 332 can be made shorter in the horizontal direction. Specifically, it can be understood that the first rib 331 has a first side 3111, and the second rib 332 has a second side 3321, and the distance from the first side 3111 to the barrel portion 310 is greater than the distance from the second side 3321 to the barrel portion 310. To further explain in detail, as shown in Figure 4, the distance from the first side 3111 of the first rib 331 to the cylindrical portion 310 along the horizontal direction is D1, and D1 gradually decreases from top to bottom. The distance from the second side 3321 of the second rib 332 to the cylindrical portion 310 along the horizontal direction is D2, and D2 also gradually decreases from top to bottom. Moreover, on the same horizontal plane, D1 is greater than D2. It can also be understood that the length of the first rib 331 along the horizontal direction is greater than the length of the second rib 332 along the horizontal direction. It can also be understood that the first rib 331 is longer and the second rib 332 is shorter. It should be noted that, after such arrangement, the long and short rib structures increase the degree of structural irregularity, further hinder the entanglement of hair, and improve the anti-hair entanglement effect. At the same time, it also increases the distance from the second rib 332 to the shell 100, which can improve the fluidity of the airflow, and the flocculent dust and garbage can also smoothly pass over the second rib 332, and the flocculent dust and garbage can be more evenly distributed on the periphery of the barrel 310.

[0052] It can be understood that, as shown in FIG. 4 , according to some embodiments of the present application, the horizontal cross-section of the cylindrical portion 310 is elliptical, and the first rib 331 and the second rib 332 are respectively located at both ends of the cylindrical portion 310 along the length direction.

[0053] It can be understood that, with reference to Figures 1 and 4, according to some embodiments of the present application, the coarse ash separator 200 and the ash pressing part 320 can be a rotating body, the coarse ash separator 200 has a first busbar 222, and the angle between the first busbar 222 and the vertical direction is A, the ash pressing part 320 has a second busbar 321, and the angle between the second busbar 321 and the vertical direction is B, A and B satisfy: 1°≤A≤30°, 1°≤B≤30°. Within this value range, the space between the coarse ash separator 200 and the ash pressing part 320 and the shell 100 can be larger, which is convenient for dust and garbage to pass through, while ensuring that the slope of the first busbar 222 and the second busbar 321 is larger, and the anti-hair entanglement effect is better. Specifically, A can be 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29° or 30°, and B can be 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29° or 30°. In some embodiments, A and B can preferably be 3.5°. It is understandable that the slope of the first busbar 222 and the slope of the second busbar 321 may be the same or different.

[0054] It can be understood that, referring to Figures 1 and 4, according to some embodiments of the present application, the coarse ash separator 200 includes a shell 210 and a filter screen 220, the filter cavity 211 is arranged in the shell 210, and the filter hole 221 of the coarse ash separator 200 is arranged on the filter screen 220. There are multiple filter holes 221, and the multiple filter holes 221 are arranged along the circumference of the filter screen 220. The filter screen 220 has an annular structure, and the filter screen 220 is sleeved on the outer periphery of the shell 210. Specifically, the shell 210 is provided with a limit frame 212, and the filter screen 220 cooperates with the limit frame 212 to fix the filter screen 220 and prevent the filter screen 220 from falling. The outer diameter of the filter screen 220 gradually decreases from top to bottom. Since the filter screen 220 is mounted on the outer periphery of the outer shell 210, the filter screen 220 is the outer layer structure of the coarse ash separator 200. The outer diameter of the coarse ash separator 200 depends on the outer diameter of the filter screen 220. The filter screen 220 can be a rotating body. The busbar of the filter screen 220 can be understood as the first busbar 222 of the coarse ash separator 200. In some embodiments, the busbar of the filter screen 220 coincides with the second busbar 321 of the ash pressing part 320, so that the junction between the first busbar 222 and the second busbar 321 can transition more smoothly. The slope of the first busbar 222 is consistent with the slope of the second busbar 321, avoiding large mutations, making full use of the space in the cavity 110, and facilitating the airflow to swirl in the cavity 110. The overall structure is also more beautiful.

[0055] In some embodiments, the filter 220 is made of metal material, which has good structural strength, can avoid being hit by dust particles and causing structural breakage, and has good durability.

[0056] It can be understood that, referring to Figures 1 and 3, in some embodiments, the housing 210 includes a filter unit 213, which is located in the filter cavity 211. The airflow in the filter cavity 211 passes through the filter unit 213 and then flows out from the air outlet 120. The filter unit 213 can further filter dust and garbage in the airflow to improve the cleanliness of the airflow. The filter unit 213 is specifically configured as a filter plate or baffle and other structures to prevent dust particles from passing through. It is not limited to this and can also be configured as other forms of structures.

[0057] As shown in Figure 1, in some embodiments, the outer diameter of the barrel portion 310 gradually decreases from top to bottom. Alternatively, it can be understood that the width of the barrel portion 310 gradually decreases from top to bottom. When hair is entangled around the outer circumference of the barrel portion 310, the support for the hair is weakened, preventing further tension on the hair. Under the action of gravity, the hair will gradually loosen from the barrel portion 310 and fall downward. This arrangement can improve the anti-entanglement effect of hair and make it easier to remove hair when cleaning dust and garbage inside the housing 100.

[0058] It can be understood that, with reference to Figure 1, in some embodiments, the barrel portion 310 can be a rotating body, and the barrel portion 310 has a third busbar 312. The angle between the third busbar 312 and the vertical direction is C, and C satisfies: 1°≤C≤30°. Within this value range, the space between the barrel portion 310 and the shell 100 can be larger, which is convenient for dust and garbage to pass through, while ensuring that the slope of the third busbar 312 is larger and the anti-hair entanglement effect is better. Specifically, C can be taken as 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29° or 30°.

[0059] 1 and 8 , in some embodiments, the barrel can be understood as a primary cyclone separation structure, and an annular primary cyclone chamber is formed between the barrel and the housing 100. The primary cyclone chamber can also be understood as a part of the cavity 110, and the primary cyclone chamber is connected to the filter hole 221. The dust cup assembly 1000 includes a cyclone separator 400. The cyclone separator 400 can be a conical structure. The cyclone separator 400 is located in the filter chamber 211. The cyclone separator 400 can be understood as a secondary cyclone separation structure. The cyclone separator 400 is provided with a secondary cyclone chamber 410. The secondary cyclone chamber 410 connects the filter chamber 211 with the dust collecting chamber 311. The cyclone separator 400 has an opening 420 at the bottom, which can connect the secondary cyclone chamber 410 with the dust collecting chamber 311.

[0060] Specifically, when the dust cup assembly 1000 is working, the external airflow enters the cavity 110 from the air inlet 130, and the airflow first rotates in the first-level cyclone chamber, throwing the dust and garbage onto the inner wall of the shell 100, thereby separating the dust and garbage and realizing first-level cyclone separation. Then, the airflow can enter the filter chamber 211 through the filter hole 221. Since the filter hole 221 is small, the filter hole 221 can filter out large clumps of dust and garbage. After entering the filter chamber 211, the airflow continues to enter the second-level cyclone chamber 410 in the cyclone separator 400. The airflow fully swirls in the second-level cyclone chamber 410, throwing out the fine dust and garbage entrained therein. Under the action of gravity, the fine dust and garbage fall into the dust collecting chamber 311 below through the opening 420, realizing second-level cyclone separation. Then, the clean airflow flows upward, thereby leaving the second-level cyclone chamber 410 and the filter chamber 211, and finally flows out from the air outlet 120.

[0061] It can be understood that, referring to Figures 1 and 8, in some embodiments, part of the structure of the cyclone separator 400 is located inside the barrel portion 310, the inner diameter of the barrel portion 310 gradually decreases from top to bottom, and the outer diameter of the cyclone separator 400 gradually decreases from top to bottom, so that the cyclone separator 400 has a roughly conical structure, which can improve the swirling effect, so that the inner wall of the barrel portion 310 and the outer wall of the cyclone separator 400 can fit tightly together, which plays a limiting role on the cyclone separator 400 and prevents the cyclone separator 400 from shaking.

[0062] It is understood that, with reference to Figures 4 and 5, in some embodiments, the ash pressing portion 320 is provided with a through hole 340. It should be noted that, during operation, the airflow between the ash pressing portion 320 and the housing 100 is constantly rotating, and the airflow between the barrel portion 310 and the ash pressing portion 320 is also constantly rotating. The airflows at the two positions can circulate with each other through the through hole 340, which can balance the air pressure and avoid the air pressure on one side being higher and the air pressure on the other side being lower, thereby affecting the swirl effect of the airflow. Specifically, there can be multiple through holes 340, and the through holes 340 can be arranged at the upper position of the ash pressing portion 320.
