[0047] In summary, by adopting the above technical solution, this utility model has the following advantages over the prior art:

[0048] Beneficial effects:

[0049] 1. The dust cup of this utility model is rotatably installed inside the dust cup via a cyclone assembly. When the vacuum cleaner is in use, the dust-laden airflow drawn into the dust cup will push the first guide plate, causing the cyclone assembly to rotate as a whole, similar to a wind-driven brush. The dust and hair trapped by the rotating cone mesh will not adhere to or remain on the cyclone assembly. Instead, they will be peeled off, thrown out, and fall to the bottom of the dust cup for unified collection due to the centrifugal force generated by its rotation. This avoids the problems of hair entanglement and dust adhesion and embedding on the surface of common dust cup filter structures, which lead to reduced filtration and flow efficiency and inconvenient subsequent cleaning.

[0050] 2. The spiral-shaped first guide plate design can work with the spiral airflow inside the cyclone assembly when the dust cup is used, as well as the setting of the second guide plate and the spiral-shaped guide cavity, to achieve a more sufficient and stable airflow drive for the cyclone assembly, so as to ensure the effect of airflow acceleration and the removal and throwing off of hair and dust from its surface.

[0051] 3. The detachable design of the rotating cone mesh and cyclone turbine structure facilitates easy disassembly and assembly for necessary surface cleaning, maintenance, and replacement, reducing the cost and difficulty of replacing dust cup parts. The arc-shaped connector allows the HEPA filter body to move within a certain range, preventing the filter holes from being compacted due to overall compression, which would affect filtration and flow quality. The dust cup has an internal layer that can be used to fill the sound insulation and sound absorption components, thereby reducing the operating noise of the vacuum cleaner dust cup and improving the user experience. The dust cup also features a concealed design at the hinge between the bottom cover assembly and the dust cup body, ensuring a clean appearance and eliminating obvious gaps, preventing damage to personnel and the dust cup caused by pinching or other objects getting stuck, and preventing the dust cup from being unable to open or close.

[0052] 4. The cyclone dust guide seat is designed so that hair and dust on the surface of the cyclone assembly are thrown to the spiral dust guide surface and connecting wedge-shaped arc surface inside the outer dust discharge chamber. Guided by the spiral structure that gradually tapers inward from top to bottom, the dust is discharged to the bottom. During this process, the internal airflow propels it to move stably and exit the separation chamber from the dust discharge port, settling to the bottom of the dust collection chamber. This achieves full discharge, guidance, and collection of hair and dust, preventing the hair and dust from spreading throughout the separation chamber and hindering their fall and movement into the dust collection chamber. The elastic sealing ring allows for variable dimensions and flexible design of the top of the cyclone dust guide seat. While ensuring a seal with the inner shell and fully catching the hair and dust that comes out of the separation chamber, the design also includes a structural avoidance feature for the opening and closing of the bottom cover assembly, facilitating opening, closing, and dust removal.

[0073] In the description of the embodiments of this utility model, it should be noted that the terms "upper" and "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0075] Example 1:

[0076] Please see Figure 1-9 This utility model provides a technical solution: a self-rotating cyclone anti-tangling dust cup, comprising:

[0077] The dust cup body 1 includes an outer shell 11 and an inner shell 12 positioned inside the outer shell 11;

[0078] An air inlet 13 is obliquely and through the outer shell 11 and the inner shell 12. A separation cavity 121 is formed inside the inner shell 12 and communicates with the air inlet 13. The separation cavity 121 is connected to the dust collection cavity 14 at the bottom of the outer shell 11.

[0079] The above design separates the air intake, filtration separation, and dust collection and storage areas inside the dust cup. This ensures stable tangential air intake in the dust cup, with the airflow drawn into the filtration structure to complete gas-solid separation. Hair and dust are efficiently and fully collected and stored at the bottom of the dust cup, avoiding mutual disturbance between areas. Airflow in other areas can cause the dust settled in the dust collection chamber 14 to be stirred up again, forming dust. This dust can collide with hair and dust that have not been separated or have been filtered and separated and are in a settling state carried by the upper airflow, leading to a slowdown in the efficiency of dust cup filtration separation and dirt settling.

[0080] Cyclone assembly 2 includes an inverted cone-shaped rotating cone mesh 21 and a cyclone turbine 22 positioned inside the rotating cone mesh 21;

[0081] The rotating cone mesh 21 has filter mesh holes 211 on its side, and the cyclone turbine 22 has a first guide plate 23 positioned on its outer side and positioned with the rotating cone mesh 21. A rotating shaft 24 extends from the cyclone turbine 22.

[0082] The design of the first guide plate 23 on the cyclone turbine 22 can not only drive the cyclone component 2 to rotate when the dust-laden airflow is in use, so as to throw out hair and dust from the surface, but also accelerate and guide the internal airflow, reduce the operating power consumption of the motor in the vacuum cleaner main unit, ensure a stable and strong airflow inside the vacuum cleaner and dust cup, and ensure efficient and sufficient dust collection, cleaning, filtration and separation and hair and dust settling functions.

[0083] The HEPA filter assembly 3 includes a connecting seat 31 and a HEPA filter structure 34 positioned on top of the connecting seat 31 to ensure stable placement of the HEPA filter, making the secondary filtration of the HEPA filter in the downwind direction of the dust cup cyclone assembly 2 more stable and sufficient.

[0084] The connecting seat 31 is provided with a connecting pipe 32 that rotates and connects to the cyclone assembly 2 in the middle. The rotating shaft 24 is rotatably connected to the central inner tube 321 of the connecting pipe 32. The cyclone assembly 2 rotates and connects to the connecting seat 31, which can improve its rotational stability.

[0085] The bottom cover assembly 4 is hinged to and sealed at the bottom of the dust cup body 1 on one side. In this embodiment, the other side can be controlled by a conventional magnetic or spring-loaded button structure or other conventional dust cup bottom cover or top cover positioning and locking design.

[0086] This invention's dust cup utilizes a cyclone assembly—the rotatable filter structure within the dust cup—which, during vacuum cleaner use, allows the dust-laden airflow drawn into the dust cup to push the first guide plate, causing the cyclone assembly to rotate like a wind-driven brush. Dust and hair trapped by the rotating cone mesh are prevented from adhering to or remaining on the cyclone assembly; instead, they are stripped away and flung off by the centrifugal force generated during rotation, falling to the bottom of the dust cup for unified collection. This avoids the common problems of hair entanglement and dust adhesion / embedding on the surface of dust cup filters, and the reduced airflow velocity at the vacuum cleaner's air intake and internal components due to rapid clogging of the filter structure during use, which hinders efficient dust collection, cleaning, and filtration. Furthermore, during operation, the synchronous rotation of the cyclone turbine assists the vacuum cleaner's internal motor in generating a stronger airflow, further improving dust collection and filtration efficiency.

[0087] The filter mesh 211 is spirally arranged on the side of the rotating cone mesh 21. The rotating cone mesh 21 and the cyclone turbine 22 are an integral structure. The first guide plate 23 extends spirally outward along the axis of the cyclone turbine 22 to the outer surface of the rotating cone mesh 21. The spiral design of the first guide plate 23 can work with the spiral airflow in the cyclone assembly 2 when the dust cup is in use to achieve a more sufficient and stable airflow drive for the cyclone assembly 2, so as to ensure the effect of airflow acceleration, hair and dust removal from the surface, and reduce the power consumption of the vacuum cleaner, dust collection and filtration efficiency, and the frequency and difficulty of subsequent dust cup cleaning.

[0088] The bottom of the rotating shaft 24 is detachably inserted into the positioning hole 221 at the top of the cyclone turbine 22. The surface of the rotating shaft 24 is provided with snap-fit ​​ribs 241 corresponding to the inner sidewall of the positioning hole 221. In this embodiment, the snap-fit ​​ribs 241 are rib structures with triangular cross-sections, equidistantly arranged along the circumferential direction of the sidewall of the rotating shaft 24, extending axially, and axially inserted and snapped into the positioning hole 221. The detachable design of the rotating cone mesh 21 and the cyclone turbine 22 facilitates convenient disassembly and assembly for necessary surface cleaning, maintenance, and replacement, reducing the cost and difficulty of replacing dust cup accessories.

[0089] The top of the rotating shaft 24 is axially positioned and rotatably connected to the mounting holes 322 of the central inner tube 321 through several bearings 242, which makes the rotation of the cyclone assembly 2 more resistant and smooth, and improves the structural transmission efficiency.

[0090] The top edge 212 of the rotating cone net 21 is inserted into and axially positioned, and rotatably connected to the bottom edge 323 of the connecting pipe 32, thereby improving the assembly stability of the cyclone assembly 2 and the rotating structure of the connecting seat 31 and preventing lateral or axial displacement when driven by wind.

[0091] The outer surface of the central inner tube 321 is positioned on the connecting tube 32 by a spiral second guide plate 324;

[0092] The connecting seat 31 is provided with a cyclone guide seat 33 on the outside of the connecting pipe 32, and the spiral guide cavity 331 on the cyclone guide seat 33 is spirally connected to the cavity formed between several second guide plates 324;

[0093] Through the air duct structure design at the air outlet of the cyclone assembly 2 on the dust cup, the second guide plate 324 and the spiral guide cavity 331 can accelerate the dust-gas separation and air outlet of the cyclone assembly 2, thereby increasing the overall airflow velocity inside the dust cup and ensuring stable dust collection, filtration and dust reduction.

[0094] L-shaped reinforcing ribs 332 are provided between the upper and lower layers of the spiral structure of the flow guide cavity 331. The HEPA structure 34 is inserted and positioned at the top of the cyclone guide seat 33, and the reinforcing ribs 332 support the bottom of the HEPA structure 34. The reinforcing ribs 332 can improve the structural strength of the spiral structure on the cyclone guide seat 33 and provide stable support and positioning for the HEPA structure 34, so as to facilitate disassembly and assembly.

[0095] The HEPA structure 34 includes a first socket 341, a second socket 342 that is interference-fitted into the inner cavity of the first socket 341 from bottom to top, and a HEPA body 343 positioned in the inner cavity of the second socket 342.

[0096] The flexible sealing ring 344 on the outer side of the first sleeve 341 is in sealing contact with the cyclone guide seat 33;

[0097] The bottom of the second socket 342 is provided with a positioning ring 345 that abuts against the bottom edge of the first socket 341;

[0098] The multi-layer nested design of the above-mentioned HEPA structure 34 can achieve interference fit between structures and improve the positioning stability of the HEPA body 343.

[0099] The inner top wall of the second set 342 is connected by an arc-shaped connector 346 to a mesh plate 347 for supporting and positioning the top surface of the HEPA filter body 343. The arc-shaped connector 346 can cooperate with the conical interference pre-tightening structure of the two sets to achieve axial top surface positioning of the HEPA filter body 343, and allow the HEPA filter body 343 to move within a certain range when the dust cup is in use and airflow is in, so as to avoid overall compression that would cause the filter holes to be compacted, affecting the filtration and flow quality.

[0100] The top of the bottom cover assembly 4 is eccentrically connected to a sealing plate 42 via a sleeve 411, and the insertion tube 421 at the bottom of the sealing plate 42 is circumferentially locked and inserted into the sleeve 411.

[0101] The sealing plate 42 is assembled at the bottom of the inner shell 12 and seals the bottom of the separation cavity 121;

[0102] The inner shell 12 has a connecting notch 122 on its side, which connects the separation chamber 121 and the ash collection chamber 14.

[0103] This design is used for the separation of the internal cavity of the dust cup, the separation chamber 121 and the dust collection chamber 14. The hair and dust thrown out by the cyclone assembly 2 are discharged from the separation chamber 121 through the connecting gap 122 and stably settle to the bottom of the dust collection chamber 14, avoiding the problem of secondary dust.

[0104] The working principle of the self-rotating cyclone anti-tangling dust cup in this embodiment includes: When the dust cup is working, the motor in the vacuum cleaner main unit creates a negative pressure environment inside the vacuum cleaner. Airflow is drawn in through the vacuum cleaner's air collection port and enters the dust cup through the air inlet 13. The dust-laden airflow enters the separation chamber 121 and is drawn into the rotating cone mesh 21. The filter mesh 211 traps hair and dust in the airflow. Under the spiral guidance of the first guide plate 23, the second guide plate 324, and the guide chamber 331, the filtered airflow is accelerated and enters the HEPA body 343 for secondary filtration. After that, the clean airflow is discharged from the dust cup. The airflow will also generate thrust on the first guide plate 23, causing the cyclone assembly 2 to rotate as a whole, which peels off and throws out the hair and dust on the surface of the rotating cone mesh 21. The hair and dust are discharged from the separation chamber 121 through the connecting notch 122, enter the dust collection chamber 14, and settle on their own, achieving unified collection. This design avoids the common problems of hair entanglement and dust adhesion / embedding on the surface of dust cup filters, preventing the vacuum cleaner's air intake and internal airflow velocity from decreasing due to rapid clogging during use, thus hindering efficient dust collection, cleaning, and filtration. Furthermore, during operation, the synchronous rotation of the cyclone turbine assists the internal motor of the vacuum cleaner in generating a stronger airflow, improving dust collection and filtration efficiency.

[0105] Example 2:

[0106] Please see Figure 2 , 3 7. Based on the above embodiment 1, preferably, a first interlayer 15 is formed between the outer shell 11 and the inner shell 12, and a second interlayer 313 is formed between the connecting seat 31 and the cyclone guide seat 33;

[0107] The first interlayer 15 and the second interlayer 313 are filled with sound insulation components. In this embodiment, the sound insulation components can be sound-absorbing and sound-insulating cotton or other common flexible fillers to achieve sound absorption and sound insulation treatment at a series of noise sources such as the cyclone component 2 and the HEPA structure 34 inside the dust cup, thereby reducing the operating noise of the vacuum cleaner dust cup and improving the user experience.

[0108] The top of the first interlayer 15 is provided with an arc-shaped positioning strip 151, and the arc-shaped groove 311 on the side of the connecting seat 31 is engaged and positioned with the arc-shaped positioning strip 151.

[0109] The annular ribs 312 arranged circumferentially on the outer surface of the connecting seat 31 are sealed and positioned with the inner shell 12 through a sealing ring. This improves the positioning and sealing strength of the connecting seat 31 and the HEPA structure 34 on the dust cup body 1, ensuring that the internal air duct structure of the dust cup is sealed and leak-free, and that the cyclone assembly 2 is used stably.

[0110] Example 3:

[0111] Please see Figure 9Based on the above embodiment 1, when the cyclone assembly 2 is driven by wind to rotate, although the dust and hair trapped by the rotating cone mesh can be separated and thrown out by the centrifugal force generated during its rotation and fall to the bottom of the dust cup for unified collection, this design avoids the common dust cup filter structure surface hair entanglement, dust adhesion and embedding, and the situation where the air flow rate at the vacuum cleaner's air collection port and inside the dust cup is reduced due to the rapid blockage of the filter structure during the use of the dust cup, resulting in the inability to perform efficient dust collection, cleaning and filtration separation. In addition, the synchronous rotation of the cyclone turbine can help the motor inside the vacuum cleaner to form a stronger airflow and improve the dust collection and filtration separation efficiency. However, in actual use, the thrown-out hair and dust will be spread throughout the separation chamber 121, which is not convenient to fall and move into the dust collection chamber 14. It is necessary to use an additional structure to guide the hair and dust and discharge it out of the connecting opening 122.

[0112] Therefore, preferably, a cyclone ash guide seat 5 is provided on the top of the bottom cover assembly 4, and an ash discharge cavity 51 is opened on the top of the cyclone ash guide seat 5, and the ash discharge cavity 51 is sleeved on the outside of the rotating cone mesh 21;

[0113] The inner surface of the cyclone ash guide seat 5 is provided with an inwardly inclined, inverted cone-shaped spiral ash guide surface 52 from top to bottom;

[0114] A connecting wedge-shaped arc surface 53 is embedded between the spiral dust guiding surfaces 52;

[0115] The bottom of the ash discharge chamber 51 is tangentially connected to the ash discharge port 54, and the ash discharge port 54 is connected to the connecting notch 122;

[0116] The working principle of the self-rotating cyclone anti-tangling dust cup in this embodiment includes: when the above structure is used, the hair and dust on the surface of the cyclone component 2 will be thrown onto the spiral dust guiding surface 52 and the connecting wedge-shaped arc surface 53 inside the outer dust discharge chamber 51, and guided by the spiral structure that gradually shrinks from top to bottom, and discharged to the bottom. During this period, it is driven by the airflow inside to move stably, and discharged from the separation chamber 121 from the dust discharge port 54, and settled to the bottom of the dust collection chamber 14, so as to achieve full collection of hair and dust.

[0117] The top edge of the cyclone dust guide seat 5 is provided with an elastic sealing ring 55. Since the bottom cover assembly 4 adopts a conventional rotary opening and closing structure with one side hinged and the other side locked, the setting of the elastic sealing ring 55 can realize the variable size and elastic design of the top of the cyclone dust guide seat 5. While ensuring that it is sealed with the inner shell 12 and fully receiving the hair and dust that comes out of the separation chamber 121, the structure of the bottom cover assembly 4 is designed to avoid obstacles when opening and closing, so as to facilitate its opening, closing and dust cleaning.

[0118] Example 4:

[0119] Please see Figure 3 , 4 9. Based on the above embodiment 1, in order to conceal the hinge joint between the bottom cover assembly 4 and the dust cup body 1 and improve its aesthetics, preferably, the bottom cover assembly 4 is provided with a cover 41 at the bottom, and a curved hinge 412 is provided on one side of the cover 41. The curved hinge 412 is embedded in the mounting groove 16 on the bottom side of the dust cup body 1.

[0120] The clearance notch 414 on the side sealing plate 413 of the curved hinge 412 abuts against the positioning rib 161 in the mounting groove 16;

[0121] The hinge shaft on the outer side of the side sealing plate 413 is laterally inserted into the guide groove 171 of the hinge ear 17 on the outer side of the mounting groove 16 and can be rotatably locked into the hinge groove 172.

[0122] The working principle of the self-rotating cyclone anti-tangling dust cup in this embodiment includes: when the dust cup is closed, the cover 41 is pushed so that the side sealing plate 413 on it rotates along the hinge ear 17, and the curved hinge 412 is inserted into the mounting groove 16. When the clearance notch 414 abuts against the positioning rib 161, the positioning of the bottom cover assembly 4 is completed, and it can be locked with the dust cup body 1. This allows the curved hinge 412 to be fully concealed in the mounting groove, ensuring the appearance while making it without obvious gaps, avoiding the problems of personnel and dust cup damage caused by pinching hands or other objects getting stuck, and the dust cup being unable to open or close.

[0123] In summary, due to the adoption of the above technical solution, the self-rotating cyclone anti-tangling dust cup of this embodiment has the following beneficial effects compared with the prior art:

[0124] 1. The dust cup of this utility model is rotatably installed inside the dust cup via a cyclone assembly. When the vacuum cleaner is in use, the dust-laden airflow drawn into the dust cup will push the first guide plate, causing the cyclone assembly to rotate as a whole, similar to a wind-driven brush. The dust and hair trapped by the rotating cone mesh will not adhere to or remain on the cyclone assembly. Instead, they will be peeled off, thrown out, and fall to the bottom of the dust cup for unified collection due to the centrifugal force generated by its rotation. This avoids the problems of hair entanglement and dust adhesion and embedding on the surface of common dust cup filter structures, which lead to reduced filtration and flow efficiency and inconvenient subsequent cleaning.

[0125] 2. The spiral-shaped first guide plate design can work with the spiral airflow inside the cyclone assembly when the dust cup is used, as well as the setting of the second guide plate and the spiral-shaped guide cavity, to achieve a more sufficient and stable airflow drive for the cyclone assembly, so as to ensure the effect of airflow acceleration and the removal and throwing off of hair and dust from its surface.

[0126] 3. The detachable design of the rotating cone mesh and cyclone turbine structure facilitates easy disassembly and assembly for necessary surface cleaning, maintenance, and replacement, reducing the cost and difficulty of replacing dust cup parts. The arc-shaped connector allows the HEPA filter body to move within a certain range, preventing the filter holes from being compacted due to overall compression, which would affect filtration and flow quality. The dust cup has an internal layer that can be used to fill the sound insulation and sound absorption components, thereby reducing the operating noise of the vacuum cleaner dust cup and improving the user experience. The dust cup also features a concealed design at the hinge between the bottom cover assembly and the dust cup body, ensuring a clean appearance and eliminating obvious gaps, preventing damage to personnel and the dust cup caused by pinching or other objects getting stuck, and preventing the dust cup from being unable to open or close.

[0127] 4. The cyclone dust guide seat is designed so that hair and dust on the surface of the cyclone assembly are thrown to the spiral dust guide surface and connecting wedge-shaped arc surface inside the outer dust discharge chamber. Guided by the spiral structure that gradually tapers inward from top to bottom, the dust is discharged to the bottom. During this process, the internal airflow propels it to move stably and exit the separation chamber from the dust discharge port, settling to the bottom of the dust collection chamber. This achieves full discharge, guidance, and collection of hair and dust, preventing the hair and dust from spreading throughout the separation chamber and hindering their fall and movement into the dust collection chamber. The elastic sealing ring allows for variable dimensions and flexible design of the top of the cyclone dust guide seat. While ensuring a seal with the inner shell and fully catching the hair and dust that comes out of the separation chamber, the design also includes a structural avoidance feature for the opening and closing of the bottom cover assembly, facilitating opening, closing, and dust removal.

[0128] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
