DETAILED DESCRIPTION

[0032] 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.

[0033] Referring to Figures 1 and 2, the dust cup assembly 1000 of an embodiment of the present application can be understood as a partial structure of a vacuum cleaner. The dust cup assembly 1000 includes a shell 100 and a filter cartridge 200. A cavity 140 is provided in the shell 100. The filter cartridge 200 is located in the cavity 140. The filter cartridge 200 can be understood as a filtering structure or a dust collecting structure. The filter cartridge 200 is mainly used to filter or collect dust and garbage entrained in the air flow.

[0034] 3 and 5 , the shell 100 includes an inner wall 110, and part of the structure of the inner wall 110 is convex inward to form a first convex wall 111 and a second convex wall 112. The first convex wall 111 and the second convex wall 112 are arranged opposite to each other. Specifically, the shell 100 is also provided with a locking structure 120 and a rotating structure 130. The dust cup assembly 1000 also includes a bottom cover 400, one end of the bottom cover 400 is rotatably connected to the rotating structure 130, and the other end of the bottom cover 400 is buckled with the locking structure 120. The locking structure 120 is located at the first convex wall 111, and the rotating structure 130 is located at the second convex wall 112. Since the first convex wall 111 and the second convex wall 112 protrude inward, the first convex wall 111 can avoid the locking structure 120, and the second convex wall 112 can avoid the rotating structure 130, which plays a role of giving way and can reduce the space occupied by the shell 100. It is understood that in some embodiments, the first convex wall 111 and the second convex wall 112 may protrude inward for other reasons. For example, due to environmental space limitations or the need to install other structures at that location, the first convex wall 111 and the second convex wall 112 are used to avoid these structures, thereby reducing the space occupied by the housing 100. In some embodiments, the inner wall 110 may also include only the first convex wall 111 or the second convex wall 112.

[0035] 1 and 4 , the housing 100 is further provided with an air inlet 160 and an air outlet 150. The air inlet 160 is in communication with the cavity 140. The airflow entering the cavity 140 from the air inlet 160 is first filtered by the filter cartridge 200 before flowing out from the air outlet 150. During operation, external airflow enters the cavity 140 from the air inlet 160. Due to the cylindrical structure of the housing 100, the airflow continuously rotates in the cavity 140, throwing dust and garbage onto the inner wall 110 of the housing 100. The airflow in the cavity 140 enters the filter cartridge 200, where the dust and garbage are filtered, making the airflow in the filter cartridge 200 relatively clean. Then, the airflow in the filter cartridge 200 flows out from the air outlet 150.

[0036] 2 and 4 , the filter cartridge 200 includes a body portion 210 . The body portion 210 is a cylindrical structure. The body portion 210 is a hollow structure. The airflow in the cavity 140 can enter the body portion 210 . Specifically, as shown in Figure 3, when viewed from a top-down angle, the barrel portion 210 has a length and a width, and the length of the barrel portion 210 is greater than the width of the barrel portion 210. It can also be understood that the maximum length of the barrel portion 210 is greater than the maximum width of the barrel portion 210. One end of the barrel portion 210 along the width direction faces the first convex wall 111, and the other end of the barrel portion 210 along the width direction faces the second convex wall 112. After such an arrangement, due to the smaller width of the barrel portion 210, the distance between the barrel portion 210 and the first convex wall 111 in the horizontal direction and the distance between the barrel portion 210 and the second convex wall 112 in the horizontal direction can be increased. It can also be understood that the space between the barrel portion 210 and the inner wall 110 is increased, making it easier for large clumps of garbage to pass through, alleviating the problem that large clumps of garbage are easily stuck at this position, so that the dust collecting base station 2000 can more easily clear the garbage in the shell 100, thereby improving the user experience. In addition, since the length of the cylindrical portion 210 is relatively large, the cylindrical portion 210 can block part of the airflow, thereby reducing the flow rate of the airflow at the position around the cylindrical portion 210, so that the dust and garbage at the bottom of the shell 100 are not easily flipped up by the airflow, and the dust and garbage can remain accumulated at the bottom of the shell 100.

[0037] Specifically, as shown in Figure 3, the distance between the cylindrical portion 210 and the first convex wall 111 is D1, and the distance between the cylindrical portion 210 and the second convex wall 112 is D2. Since the width of the cylindrical portion 210 becomes smaller, both D1 and D2 are increased, that is, the space between the cylindrical portion 210 and the inner wall 110 is increased, which is more conducive to the passage of large clumps of garbage, and large clumps of garbage are not easily stuck.

[0038] It should be noted that although the length of the cylindrical portion 210 is relatively large, there is no large protrusion at the inner wall 110 opposite the two ends of the cylindrical portion 210 along the length direction. Therefore, the space between the two ends of the cylindrical portion 210 along the length direction and the inner wall 110 is relatively sufficient to allow large clumps of garbage to pass through smoothly.

[0039] It is understood that the embodiments of the present application also provide a vacuum cleaner, which includes the dust cup assembly 1000 of the above embodiment. The embodiments of the present application also provide a cleaning device, which includes the vacuum cleaner of the above embodiment and a dust collection base station 2000. The dust collection base station 2000 is used to collect garbage in the housing 100, and the dust collection base station 2000 has a dust collection chamber 2100. 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 it to clean the interior. In this embodiment, after the dust collection base station 2000 is installed, the dust cup assembly 1000 can be removed and installed on the dust collection base station 2000. The bottom cover 400 of the dust cup assembly 1000 is then opened, connecting the cavity 140 of the housing 100 with the dust collection chamber 2100 of the dust collection base station 2000. The fan in the dust collection base station 2000 generates suction to completely draw out the dust in the dust cup assembly 1000. Specifically, as shown in FIG4 , the dust moves downward in the direction of the arrow, from the cavity 140 of the housing 100 into the dust collection chamber 2100 of the dust collection base station 2000, achieving the effect of automatically cleaning the dust cup assembly 1000. This facilitates operation and improves the user experience. Furthermore, the dust cup assembly 1000 of this embodiment features an optimized structure, increasing the space between the filter cartridge 200 and the inner wall 110, making it easier to draw out large clumps of garbage from the cavity 140, thus improving the user experience of the dust collection base station 2000.

[0040] 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, the bottom cover 400 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 and increased the space between the barrel 210 and the inner wall 110, large clumps of garbage are not easily stuck, and large clumps of garbage in the shell 100 can be easily removed.

[0041] It can be understood that, as shown in FIG3 , in some embodiments, the horizontal cross-section of the cylindrical portion 210 is elliptical. With respect to this elliptical shape, one end of the minor axis of the ellipse faces the first convex wall 111, and the other end faces the second convex wall 112. That is, the two ends of the ellipse in the width direction respectively face the first convex wall 111 and the second convex wall 112. Specifically, it can also be understood that the first convex wall 111 and the second convex wall 112 are arranged on the left and right sides, and the minor axis of the ellipse extends in the left-right direction, with the left side of the minor axis facing the first convex wall 111 and the right side of the minor axis facing the first convex wall 111. The major axis of the ellipse extends in the front-to-back direction.

[0042] It is understandable that in some embodiments, the horizontal cross-section of the barrel portion 210 may also be rectangular, diamond-shaped, or racetrack-shaped, so that the length of the barrel portion 210 is greater than the width of the barrel portion 210, and there is no limitation here.

[0043] As shown in Figure 4, according to some embodiments of the present application, the cylindrical portion 210 can be a rotating body structure, the cylindrical portion 210 has a first busbar 211, the cylindrical portion 210 can be a cylindrical structure, or the cylindrical portion 210 can also be a conical structure or a structure approximately similar to a truncated cone. The first busbar 211 of the cylindrical portion 210 is tilted so that the width of the cylindrical portion 210 gradually decreases from top to bottom. It can also be understood that the cylindrical portion 210 has a taper, the outer diameter of the cylindrical portion 210 gradually decreases from top to bottom, and the distance from the first busbar 211 to the shell 100 in the horizontal direction gradually increases from top to bottom. Since the width of the cylindrical portion 210 decreases as it goes downward, the distance between the cylindrical portion 210 and the inner wall 110 increases. Furthermore, the first convex wall 111 and the second convex wall 112 are located at the bottom of the housing 100. This arrangement precisely corresponds to the positions of the first convex wall 111 and the second convex wall 112, further increasing the distance between the cylindrical portion 210 and the first convex wall 111 or the second convex wall 112, thereby increasing the space between the cylindrical portion 210 and the inner wall 110 and facilitating the passage of large clumps of garbage. Specifically, when the horizontal cross-section of the cylindrical portion 210 is elliptical, it can also be understood that the area of ​​the horizontal cross-section of the cylindrical portion 210 gradually decreases from top to bottom, that is, the minor axis of the ellipse in the horizontal cross-section continuously shortens, further increasing the distance between the cylindrical portion 210 and the first convex wall 111 or the second convex wall 112.

[0044] It can be understood that, with reference to Figures 2 and 4, according to some embodiments of the present application, the first convex wall 111 includes a first inclined section 1111, the second convex wall 112 includes a second inclined section 1121, the first inclined section 1111 and the second inclined section 1121 both protrude inward, and the first inclined section 1111 and the second inclined section 1121 are inclined so that the distance from the first inclined section 1111 to the second inclined section 1121 along the horizontal direction gradually decreases. When a large clump of garbage is located at the position of the first inclined section 1111 or the second inclined section 1121, since the first inclined section 1111 or the second inclined section 1121 has a certain slope, the garbage can be guided to fall, and the large clump of garbage can slide relatively smoothly along the surface of the first inclined section 1111 or the second inclined section 1121, thereby alleviating the problem of large clumps of garbage being easily stuck. In addition, since the first inclined section 1111 or the second inclined section 1121 has a certain slope, the transition is relatively smooth, which can avoid a large mutation in the wall surface at the position of the first convex wall 111 and the second convex wall 112, which may cause a large mass of garbage to be stuck.

[0045] 2 and 4 , according to some embodiments of the present application, the first oblique section 1111 is located above the second oblique section 1121, and the first convex wall 111 includes a vertical section 1112. The vertical section 1112 is located below the first oblique section 1111, and the upper end of the vertical section 1112 is connected to the lower end of the first oblique section 1111. The vertical section 1112 is arranged opposite the second oblique section 1121. The provision of the vertical section 1112 increases the horizontal distance from the vertical section 1112 to the second oblique section 1121, facilitating the passage of large clumps of garbage and alleviating the problem of large clumps of garbage being easily stuck. Furthermore, the transition of the vertical section 1112 is smoother, with less abrupt changes, which can prevent large clumps of garbage from getting stuck.

[0046] It will be appreciated that, referring to Figures 2 and 4 , in some embodiments, the dust cup assembly 1000 includes a coarse ash separator 300 and a cyclone separator 500, and the filter cartridge 200 serves as a fine ash collector. The fine ash collector is disposed below the coarse ash separator 300, and the fine ash collector and the coarse ash separator 300 are connected via a snap. During installation, the cyclone separator 500 is placed into the fine ash collector, which is then directly aligned with the coarse ash separator 300. The fine ash collector is then rotated, and the fine ash collector is fastened to the coarse ash separator 300 via the snap, making installation relatively convenient.

[0047] Specifically, as shown in Figures 2 and 4 , the cyclone separator 500 is located between the fine ash collector and the coarse ash separator 300. The coarse ash separator 300 is primarily used to filter large clumps of dust and debris entrained in the airflow. The cyclone separator 500 is primarily used to further separate dust and debris within the coarse ash separator 300 and improve the swirling effect of the airflow. The fine ash collector is primarily used to collect fine dust and debris separated by the cyclone separator 500. Specifically, the coarse ash separator 300 includes a housing 310 and a filter 320. The filter 320 has an annular structure and is sleeved around the outer periphery of the housing 310. The housing 310 is provided with a retaining frame 312. The filter 320 cooperates with the retaining frame 312 to secure the filter 320 and prevent it from falling. A filter chamber 311 is provided in the outer shell 310, and the filter chamber 311 is connected to the air outlet 150 of the shell 100. The filter net 320 is provided with a filter hole 321, and the filter hole 321 connects the filter chamber 311 and the cavity 140 of the shell 100. The bottom of the cylindrical portion 210 of the fine ash collector abuts against the bottom cover 400, thereby defining a dust collecting chamber 230 in the cylindrical portion 210. A cyclone chamber 510 is provided in the cyclone separator 500. The cyclone separator 500 is a hollow structure. The upper part of the cyclone separator 500 is located in the filter chamber 311, and the lower part of the cyclone separator 500 is located in the dust collecting chamber 230. The cyclone chamber 510 connects the filter chamber 311 and the dust collecting chamber 230.

[0048] Specifically, when the dust cup assembly 1000 is working, the external airflow enters the cavity 140 from the air inlet 160, and the airflow rotates in the cavity 140. The airflow can pass through the filter hole 321 and enter the filter chamber 311. Since the filter hole 321 is small, the filter hole 321 can filter out large clumps of dust and garbage. Then, the airflow enters the filter chamber 311 and continues to enter the cyclone chamber 510 in the cyclone separator 500. The airflow fully rotates in the cyclone chamber 510 and throws out the fine dust and garbage entrained therein. At the same time, due to the action of gravity, the fine dust and garbage falls into the dust collecting chamber 230 below, and the clean airflow flows upward to leave the cyclone chamber 510 and the filter chamber 311, and finally flows out from the air outlet 150.

[0049] In some embodiments, the filter 320 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.

[0050] It should be noted that when the airflow swirls in the cavity 140, it may cause large clumps of garbage at the bottom of the cavity 140 to flip upward. When the large clumps of garbage move upward to the position of the filter hole 321, it is easy to block the filter hole 321, resulting in poor airflow, thereby reducing the suction force of the vacuum cleaner's fan and affecting the dust collection effect.

[0051] It is understood that, as shown in Figure 1, in some embodiments, the filter cartridge 200 includes an ash pressing portion 220, which is annular in structure, connected to the cylindrical body 210, and sleeved on the outer circumference of the cylindrical body 210. Specifically, the ash pressing portion 220 is located at the upper portion of the cylindrical body 210, the length of the ash pressing portion 220 in the vertical direction is shorter than the length of the cylindrical body 210 in the vertical direction, there is a certain distance between the ash pressing portion 220 and the bottom cover 400, there is also a certain distance between the ash pressing portion 220 and the cylindrical body 210, and the width of the ash pressing portion 220 is greater than the width of the cylindrical body 210. Alternatively, it can also be understood that the outer diameter of the ash pressing portion 220 is greater than the outer diameter of the cylindrical body 210.

[0052] It should be noted that the ash pressing part 220 is mainly used to prevent dust and garbage from moving upward. When the dust cup assembly 1000 is working, the large clumps of garbage inside the shell 100 are accumulated at the bottom due to gravity. Since the airflow rotates in the shell 100, the airflow may drive the large clumps of garbage accumulated at the bottom of the shell 100 to rise upward, thereby blocking the filter holes 321 of the filter screen 320, resulting in a decrease in the suction force of the fan. After the ash pressing part 220 is set in this embodiment, when the large clumps of garbage are rolled up by the airflow and move upward, a part of them will enter the space between the ash pressing part 220 and the cylindrical part 210. The ash pressing part 220 can prevent this part of the large clumps of garbage from turning over, thereby achieving an ash pressing effect, making it difficult for the large clumps of garbage to be rolled up by the airflow, and preventing the large clumps of garbage from clogging the filter holes 321.

[0053] It should also be noted that, as shown in Figure 4, since the ash pressing part 220 has an annular structure and is sleeved on the outer periphery of the cylindrical part 210, an annular cavity is formed between the ash pressing part 220 and the cylindrical part 210. After the airflow enters the cavity 140 of the shell 100, the airflow can be guided to continuously swirl in the cavity between the ash pressing part 220 and the cylindrical part 210, thereby improving the effect of cyclone separation. Dust and garbage are thrown to the inner side of the ash pressing part 220. The ash pressing part 220 can block this part of the dust and garbage, preventing this part of the dust and garbage from moving upward, thereby improving the cleanliness of the airflow. In addition, an annular cavity is also formed between the ash pressing part 220 and the shell 100, which can guide the airflow to continuously swirl around the outer periphery of the ash pressing part 220, thereby further improving the effect of cyclone separation, separating dust and garbage, and improving the cleanliness of the airflow. Alternatively, it can also be understood that a vortex airflow is formed between the ash pressing portion 220 and the cylindrical portion 210, and another vortex airflow is formed between the ash pressing portion 220 and the shell 100. Through these two vortex airflows, multiple cyclonic separations of dust and garbage are achieved, thereby improving the cleanliness of the airflow. It can be understood that, with reference to Figure 4, according to some embodiments of the present application, the ash pressing portion 220 can be a rotating body structure, and the ash pressing portion 220 has a second busbar 222, and the second busbar 222 is tilted so that the width of the ash pressing portion 220 gradually decreases from top to bottom. It can also be understood that the outer diameter of the ash pressing portion 220 gradually decreases from top to bottom, and the distance from the second busbar 222 to the shell 100 in the horizontal direction gradually increases from top to bottom. Such a setting can alleviate the problem of hair entanglement. Specifically, when hair is entangled with the ash pressing part 220, under the action of gravity, the hair will fall slightly downward, and the width of the ash pressing part 220 where the hair is entangled will gradually decrease, so that the tension of the hair is reduced, and the hair can gradually loosen the ash pressing part 220.

[0054] It is understood that, with reference to Figures 2 and 4, in some embodiments, the ash pressing portion 220 is provided with a through hole 221. It should be noted that, during operation, the airflow between the ash pressing portion 220 and the housing 100 is constantly rotating, and the airflow between the cylindrical portion 210 and the ash pressing portion 220 is also constantly rotating. The airflows at the above two positions can circulate with each other through the through hole 221, 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, a plurality of through holes 221 can be provided, and the through holes 221 can be arranged at the upper position of the ash pressing portion 220.
