[0048] 1. The dust cup of the present invention can be rotatably arranged in the dust cup through the cyclone assembly, so that when the vacuum cleaner is in use, the dust-containing airflow sucked into the dust cup will push the first guide plate, causing the cyclone assembly to rotate as a whole like a pneumatic brush. The dust and hair trapped by the rotating cone net will not adhere to and remain on the cyclone assembly due to this design, but will be peeled off, thrown out and fall to the bottom of the dust cup for unified collection due to the centrifugal effect formed when it rotates, thereby avoiding the problems of hair entanglement on the surface of the common dust cup filter structure, dust adhesion and embedding, resulting in reduced filtering and flow efficiency, and inconvenience in subsequent cleaning.

[0049] 2. The spiral first guide plate design can cooperate with the spiral airflow in the cyclone assembly when the dust cup is used, as well as the setting of the second guide plate and the spiral guide cavity, to achieve a more sufficient and stable airflow drive of the cyclone assembly, so as to ensure the effect of accelerating the airflow and stripping off the hair and dust on its surface.

[0050] 3. The detachable design of the rotating cone net and the cyclone turbine structure facilitates subsequent convenient disassembly and assembly for necessary surface cleaning, maintenance and replacement, reducing the cost and difficulty of replacing dust cup accessories; the arc-shaped connector allows the HEPA body to move within a certain range to avoid overall compression that causes compaction of the filter holes, affecting the filtration and flow quality; the dust cup is equipped with a layer that can be used to fill sound insulation and sound absorption components to reduce the operating noise of the vacuum cleaner dust cup and improve user experience; the dust cup also has a hidden design at the hinge between the bottom cover assembly and the dust cup body to ensure the appearance without obvious gaps, avoiding problems such as pinching hands or other objects that may cause damage to personnel and the dust cup, and the inability to open and close the dust cup.

[0051] 4. The setting of the cyclone dust guide seat allows the hair and dust on the surface of the cyclone component to be thrown to the spiral dust guide surface and the connecting wedge-shaped arc surface in the outer dust discharge chamber, and be guided by the spiral structure that gradually retracts from top to bottom and discharged to the bottom. During this period, it is pushed by the airflow inside to move stably and be discharged from the separation chamber from the dust discharge port, and settle to the bottom of the ash collection chamber, so as to achieve full discharge guidance and collection of the hair and dust, and avoid the problem that the thrown hair and dust will spread throughout the separation chamber and be inconvenient to fall and move into the ash collection chamber. Through the setting of the elastic sealing ring, the size of the top of the cyclone dust guide seat can be changed and elastically designed. While ensuring its sealing with the inner shell and fully absorbing the hair and dust that escape from the separation chamber, the structural avoidance design is performed when the bottom cover assembly is opened and closed, so as to facilitate its opening and closing and cleaning.

[0074] Embodiment 1:

[0075] See also Figure 1-9 The present invention provides a technical solution: a self-rotating cyclone anti-entanglement dust cup, comprising:

[0076] The dust cup body 1 comprises an outer shell 11 and an inner shell 12 positioned inside the outer shell 11;

[0077] An air inlet 13 is obliquely provided between the outer shell 11 and the inner shell 12, and a separation chamber 121 communicating with the air inlet 13 is formed in the inner shell 12, and the separation chamber 121 is connected to the ash collecting chamber 14 at the bottom of the outer shell 11;

[0078] The above design allows the air intake, filtration separation, and dust collection and storage areas inside the dust cup to be designed separately, thereby ensuring stable tangential air intake to the dust cup. The airflow is sucked into the filtration structure to complete gas-solid separation, and the hair and dust are efficiently and fully sunk to the bottom of the dust cup for collection and storage, avoiding mutual disturbance between areas. The airflow in other areas drives the dust settled in the ash collecting chamber 14 to be raised again to form dust, which causes the dust to collide with the unseparated or filtered and separated, and settled hair and dust carried by the upper airflow, resulting in the problem of reduced efficiency of dust cup filtration separation and dirt sedimentation.

[0079] The cyclone assembly 2 comprises a rotating cone net 21 in an inverted cone shape and a cyclone turbine 22 positioned in the inner cavity of the rotating cone net 21;

[0080] The side of the rotating cone net 21 is provided with a filter mesh 211, the outer side of the cyclone turbine 22 is provided with a first guide plate 23 positioned with the rotating cone net 21, and the cyclone turbine 22 is extended with a rotating shaft 24;

[0081] The design of the first guide plate 23 on the cyclone turbine 22 can not only be used for the dust-containing airflow to drive the cyclone component 2 to rotate when the dust cup is in use, so as to throw away the hair and dust on the surface, but also realize the internal airflow speed-up and diversion, reduce the operating power consumption of the motor in the vacuum cleaner host, ensure stable and strong airflow inside the vacuum cleaner and dust cup, and ensure efficient and sufficient dust collection and cleaning, filtration separation and hair and dust sedimentation functions.

[0082] The HEPA assembly 3 includes a connecting seat 31 and a HEPA structure 34 positioned on the top of the connecting seat 31 to ensure the stable placement of the HEPA, so that the secondary filtration of the HEPA at the downwind side of the dust cup cyclone assembly 2 is more stable and sufficient.

[0083] A connecting pipe 32 rotatably docked with the cyclone assembly 2 is disposed in the middle of the connecting seat 31, and the rotating shaft 24 is rotatably connected to the central inner pipe 321 of the connecting pipe 32. The cyclone assembly 2 rotatably docks with the connecting seat 31, which can improve its rotation stability.

[0084] The bottom cover assembly 4 has one side hinged and sealed at the bottom of the dust cup body 1. In this embodiment, the other side can adopt a conventional magnetic or spring-matched button structure or other conventional dust cup bottom cover or top cover positioning and locking design for opening and closing control.

[0085] The dust cup of the present invention is rotatably arranged in the dust cup through a cyclone assembly, that is, the filtering structure inside the dust cup, so that when the vacuum cleaner is in use, the dust-containing airflow sucked into the dust cup will push the first guide plate, so that the cyclone assembly rotates as a whole like a pneumatic brush. The dust and hair trapped by the rotating cone net will not adhere to or stay on the cyclone assembly through this design, but will be peeled off, thrown out and fall to the bottom of the dust cup for unified collection due to the centrifugal effect formed when it rotates, thereby avoiding the common dust cup filter structure surface hair entanglement, dust adhesion and embedding, and the dust cup is used. The filter structure is quickly blocked during the use of the dust cup, resulting in a decrease in the air flow rate at the vacuum cleaner air collection port and the internal airflow, and the inability to perform efficient dust collection, cleaning, filtering and separation. In addition, when the design is used, the cyclone turbine rotates synchronously, which can assist the motor inside the vacuum cleaner host to form a stronger airflow, thereby improving the efficiency of dust collection and filtering separation.

[0086] The filter mesh 211 is arranged in a spiral shape on the side of the rotating cone net 21. The rotating cone net 21 and the cyclone turbine 22 are an integrated structure. The first guide plate 23 is extended outwardly along the axis of the cyclone turbine 22 to the outer surface of the rotating cone net 21 in a spiral shape. The spiral first guide plate 23 design can cooperate with the spiral airflow in the cyclone assembly 2 when the dust cup is used to achieve a more sufficient and stable airflow drive of the cyclone assembly 2, so as to ensure the effect of speeding up the airflow, peeling off the hair and dust on the surface, and reducing the power consumption of the vacuum cleaner, the dust collection and filtration efficiency, and the frequency and difficulty of subsequent dust cup cleaning.

[0087] The bottom of the rotating shaft 24 is removably inserted into the positioning hole 221 at the top of the cyclone turbine 22, and the surface of the rotating shaft 24 is provided with a snap-fitting convex rib 241 corresponding to the inner side wall of the positioning hole 221; in this embodiment, the snap-fitting convex rib 241 is a convex rib structure that is equidistantly arranged along the circumferential side wall of the rotating shaft 24, extends axially, and has a triangular cross-section, and is axially inserted and snap-fitted into the positioning hole 221. The above-mentioned detachable design of the rotating cone net 21 and the cyclone turbine 22 structure facilitates the subsequent convenient disassembly and assembly, so as to carry out necessary surface cleaning, maintenance and replacement, and reduce the cost and difficulty of replacing dust cup accessories.

[0088] The top of the rotating shaft 24 is axially positioned and rotatably connected to the mounting hole 322 of the central inner tube 321 through a plurality of bearings 242, so that the cyclone assembly 2 rotates more smoothly with lower resistance, thereby improving the transmission efficiency of the structure;

[0089] The positioning top edge 212 of the rotating cone net 21 is inserted and axially positioned and rotationally connected to the positioning bottom edge 323 of the connecting pipe 32, thereby improving the assembly stability of the rotating structure of the cyclone assembly 2 and the connecting seat 31 and avoiding lateral or axial displacement when driven by wind.

[0090] The outer surface of the central inner tube 321 is positioned on the connecting tube 32 through a spiral second guide plate 324;

[0091] The connecting seat 31 is provided with a cyclone guide seat 33 outside the connecting pipe 32, and a spiral guide cavity 331 on the cyclone guide seat 33 is spirally connected to a cavity formed between a plurality of the second guide plates 324;

[0092] Through the air duct structure design at the air outlet of the cyclone assembly 2 on the above-mentioned dust cup, the second guide plate 324 and the spiral guide cavity 331 can speed up the dust and gas separation air outlet of the cyclone assembly 2, thereby increasing the overall air flow velocity inside the dust cup and ensuring stable dust collection, filtration and dust reduction.

[0093] An L-shaped reinforcing rib 332 is provided between the upper and lower layers of the spiral structure of the guide cavity 331, and the HEPA structure 34 is inserted and positioned on the top of the cyclone guide seat 33, and the reinforcing rib 332 supports the bottom of the HEPA structure 34. The reinforcing rib 332 can improve the structural strength of the spiral structure on the cyclone guide seat 33, and stably support and position the HEPA structure 34 for easy disassembly and assembly.

[0094] The HEPA structure 34 includes a first sleeve 341, a second sleeve 342 inserted into the inner cavity of the first sleeve 341 by interference fit from bottom to top, and a HEPA body 343 positioned in the inner cavity of the second sleeve 342;

[0095] The flexible sealing ring 344 outside the first seat 341 is in sealing contact with the cyclone guide seat 33;

[0096] A positioning ring 345 is disposed at the bottom of the second seat 342 and abuts against the bottom edge of the first seat 341;

[0097] The multi-layer nested design of the above-mentioned Hypa structure 34 can achieve interference fit between structures and improve the positioning stability of the Hypa body 343.

[0098] The inner wall of the top of the second seat 342 is connected to a mesh plate 347 for supporting and positioning the top surface of the HEPA body 343 through an arc-shaped connector 346. The arc-shaped connector 346 can cooperate with the conical interference pre-tightening structure of the two seats to achieve the axial top surface positioning of the HEPA body 343, and when the dust cup is used and air flows in, the HEPA body 343 can move within a certain range to avoid the overall compression causing the filter holes to be compacted, affecting the filtering and flow quality.

[0099] The top of the bottom cover assembly 4 is eccentrically connected to a sealing plate 42 through a sleeve 411, and a plug 421 at the bottom of the sealing plate 42 is circumferentially locked and plugged into the sleeve 411;

[0100] The sealing plate 42 is assembled at the bottom of the inner shell 12 and seals the bottom of the separation chamber 121;

[0101] A communication notch 122 is disposed on the side of the inner shell 12 to communicate with the separation chamber 121 and the ash collecting chamber 14 .

[0102] This design is used for the separation design of the internal cavity separation chamber 121 of the dust cup and the ash collecting chamber 14. The hair dust thrown out by the cyclone assembly 2 is discharged from the separation chamber 121 through the connecting gap 122 and stably settles to the bottom of the ash collecting chamber 14, avoiding the problem of secondary dust.

[0103] The working principle of a self-rotating cyclone anti-entanglement dust cup of the present embodiment includes: when the dust cup is working, the motor in the vacuum cleaner main body forms a negative pressure environment inside the vacuum cleaner, the air flow is sucked in by the vacuum cleaner air collecting port, and enters the dust cup through the air inlet 13, the dust-containing air flow enters the separation chamber 121, and is sucked into the rotating cone net 21, the filter mesh 211 intercepts the hair and dust in the air flow, and the filtered air flow is accelerated by the spiral guide action of the first guide plate 23, the second guide plate 324, and the guide chamber 331 to enter the HEPA body 343 for secondary filtration, and then the clean air flow is discharged from the dust cup, and the air flow will form a thrust on the first guide plate 23, so that the cyclone assembly 2 rotates as a whole, and the hair and dust on the surface of the rotating cone net 21 are peeled off and thrown out, and the hair and dust are discharged from the separation chamber 121 through the connecting notch 122, enter the ash collecting chamber 14, and settle by themselves to achieve unified collection. This avoids the common situation where hair gets tangled on the surface of the dust cup filter structure, dust sticks and embeds, and the dust cup is used, which causes the filter structure to quickly clog, resulting in a decrease in the air flow rate at the vacuum cleaner's air collection port and inside, and the inability to perform efficient dust collection, cleaning, and filtration and separation. In addition, when this design is used, the cyclone turbine rotates synchronously, which can assist the motor inside the vacuum cleaner host to form a stronger airflow, improving the efficiency of dust collection and filtration and separation.

[0104] Embodiment 2:

[0105] See also 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;

[0106] The first interlayer 15 and the second interlayer 313 are filled with sound insulation components. In this embodiment, the sound insulation components can be made of 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 in the dust cup, reduce the operating noise of the dust cup of the vacuum cleaner, and improve user experience.

[0107] 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 assembled and positioned with the arc-shaped positioning strip 151;

[0108] The annular convex rib 312 arranged circumferentially on the outer surface of the connecting seat 31 is sealed and plugged into 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, so as to ensure that the air duct structure inside the dust cup is sealed and leak-free, and the cyclone assembly 2 is used stably.

[0109] Embodiment three:

[0110] See also Fig. 9On the basis of the above-mentioned embodiment 1, when the cyclone component 2 is driven to rotate by wind, although the dust and hair trapped by the rotating cone net will not adhere to and stay on the cyclone component through this design, but will be peeled off, thrown out and fall to the bottom of the dust cup for unified collection due to the centrifugal effect formed when it rotates, thereby avoiding the common hair entanglement on the surface of the dust cup filter structure and the adhesion and embedding of dust. During the use of the dust cup, the vacuum cleaner air inlet and the internal air flow rate are reduced due to the rapid clogging of the filter structure, and the inability to perform efficient dust collection, cleaning, filtering and separation. In addition, the synchronous rotation of the cyclone turbine can assist the internal motor of the vacuum cleaner host to form a stronger airflow, thereby improving the dust collection and filtering separation efficiency. However, when it is used in practice, the thrown hair and dust will spread throughout the separation chamber 121, which is not convenient for falling and moving into the dust collection chamber 14. It is necessary to use an additional structure to guide the hair and dust so that they are discharged from the connecting gap 122.

[0111] 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 provided on the top of the cyclone ash guide seat 5, and the ash discharge cavity 51 is sleeved outside the rotating cone net 21;

[0112] 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;

[0113] A connecting wedge-shaped arc surface 53 is embedded between the spiral ash guiding surfaces 52;

[0114] The bottom of the ash discharge cavity 51 is tangentially connected to the ash discharge port 54, and the ash discharge port 54 is connected to the communication gap 122;

[0115] The working principle of a self-rotating cyclone anti-entanglement dust cup of the present embodiment includes: when the above structure is used, the hair and dust on the surface of the cyclone component 2 will be thrown to the spiral ash guiding surface 52 and the connecting wedge-shaped arc surface 53 in the outer ash discharge chamber 51, and will be guided by the spiral structure that gradually retracts from top to bottom and discharged to the bottom. During this period, it is pushed by the airflow inside it to move stably, and is discharged from the separation chamber 121 from the ash discharge port 54, and settles to the bottom of the ash collecting chamber 14, so that the hair and dust are fully collected.

[0116] An elastic sealing ring 55 is arranged at the top edge of the cyclone dust guide seat 5. Since the bottom cover assembly 4 adopts a conventional rotary opening and closing structure with one side hinged and the other side locked, the elastic sealing ring 55 is arranged to realize a variable size and elastic design of the top of the cyclone dust guide seat 5, and while ensuring the sealing between the bottom cover assembly 4 and the inner shell 12 and fully receiving the hair and dust escaped from the separation chamber 121, the bottom cover assembly 4 is designed to avoid the structure when opening and closing, so as to facilitate its opening and closing and dust cleaning.

[0117] Embodiment 4:

[0118] See also Figure 3 , 4 9. On the basis of the above-mentioned embodiment 1, in order to improve the aesthetics of the hidden design of the hinge between the bottom cover assembly 4 and the dust cup body 1, preferably, a cover 41 is provided at the bottom of the bottom cover assembly 4, and a curved hinge 412 is provided on one side of the cover 41, and the curved hinge 412 is embedded in the mounting groove 16 on the bottom side of the dust cup body 1;

[0119] The avoidance notch 414 on the side sealing plate 413 on the side of the curved hinge 412 abuts against the positioning rib 161 in the installation groove 16;

[0120] 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 installation groove 16 and is rotatably inserted into the hinge groove 172 .

[0121] The working principle of a self-rotating cyclone anti-entanglement dust cup of the present embodiment includes: when the dust cup is closed, the cover 41 is pushed to cause the side sealing plate 413 thereon to rotate along the hinge ear 17, and the curved hinge 412 is immersed in the installation groove 16. When the avoidance 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, so that the curved hinge 412 can fully conceal the installation groove, ensuring the appearance while leaving no obvious gaps, avoiding the problem of pinching hands, other objects being embedded and causing damage to people and the dust cup, and the dust cup being unable to be opened and closed.

[0122] In summary, due to the adoption of the above technical solution, the self-rotating cyclone anti-entanglement dust cup of this embodiment has the following beneficial effects compared with the prior art:

[0123] 1. The dust cup of the present invention can be rotatably arranged in the dust cup through the cyclone assembly, so that when the vacuum cleaner is in use, the dust-containing airflow sucked into the dust cup will push the first guide plate, causing the cyclone assembly to rotate as a whole like a pneumatic brush. The dust and hair trapped by the rotating cone net will not adhere to and remain on the cyclone assembly due to this design, but will be peeled off, thrown out and fall to the bottom of the dust cup for unified collection due to the centrifugal effect formed when it rotates, thereby avoiding the problems of hair entanglement on the surface of the common dust cup filter structure, dust adhesion and embedding, resulting in reduced filtering and flow efficiency, and inconvenience in subsequent cleaning.

[0124] 2. The spiral first guide plate design can cooperate with the spiral airflow in the cyclone assembly when the dust cup is used, as well as the setting of the second guide plate and the spiral guide cavity, to achieve a more sufficient and stable airflow drive of the cyclone assembly, so as to ensure the effect of accelerating the airflow and stripping off the hair and dust on its surface.

[0125] 3. The detachable design of the rotating cone net and the cyclone turbine structure facilitates subsequent convenient disassembly and assembly for necessary surface cleaning, maintenance and replacement, reducing the cost and difficulty of replacing dust cup accessories; the arc-shaped connector allows the HEPA body to move within a certain range to avoid overall compression that causes compaction of the filter holes, affecting the filtration and flow quality; the dust cup is equipped with a layer that can be used to fill sound insulation and sound absorption components to reduce the operating noise of the vacuum cleaner dust cup and improve user experience; the dust cup also has a hidden design at the hinge between the bottom cover assembly and the dust cup body to ensure the appearance without obvious gaps, avoiding problems such as pinching hands or other objects that may cause damage to personnel and the dust cup, and the inability to open and close the dust cup.

[0126] 4. The setting of the cyclone dust guide seat allows the hair and dust on the surface of the cyclone component to be thrown to the spiral dust guide surface and the connecting wedge-shaped arc surface in the outer dust discharge chamber, and be guided by the spiral structure that gradually retracts from top to bottom and discharged to the bottom. During this period, it is pushed by the airflow inside to move stably and be discharged from the separation chamber from the dust discharge port, and settle to the bottom of the ash collection chamber, so as to achieve full discharge guidance and collection of the hair and dust, and avoid the problem that the thrown hair and dust will spread throughout the separation chamber and be inconvenient to fall and move into the ash collection chamber. Through the setting of the elastic sealing ring, the size of the top of the cyclone dust guide seat can be changed and elastically designed. While ensuring its sealing with the inner shell and fully absorbing the hair and dust that escape from the separation chamber, the structural avoidance design is performed when the bottom cover assembly is opened and closed, so as to facilitate its opening and closing and cleaning.

[0127] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
