[0038] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The various technical features of the embodiments described above may be combined arbitrarily. To simplify the description, not all possible combinations of the various technical features in the embodiments described above are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] See also Figure 1 The separation mechanism 10 in one embodiment can effectively achieve the gas-dust separation effect and at least improve the gas-dust separation efficiency. It can also effectively reduce the problem of dust-laden gas imbalance. Specifically, the separation mechanism 10 includes a dust collection assembly 100 and a cyclone separator 200.

[0042] Please also refer to Figure 2 and Figure 3 The dust collection assembly 100 is formed with a dust collection chamber 110 and at least two air inlet chambers 120 separated from the dust collection chamber 110. The at least two air inlet chambers 120 are arranged around a first axis a. The cyclone separator 200 includes a cyclone unit 230. The cyclone unit 230 has an air inlet 210 at one end and a dust exhaust port 220 at the other end. The dust exhaust port 220 is connected to the dust collection chamber 110. The number of cyclone separators 200 is the same as the number of air inlet chambers 120. The air inlet 210 of the cyclone unit 230 of each cyclone separator 200 is connected to the corresponding air inlet chamber 120.

[0043] When the separation mechanism 10 is in use, the dust exhaust port 220 of the cyclone separator 200 communicates with the dust collection chamber 110 of the dust collection assembly 100. At least two air inlet chambers 120 are arranged around the first axis a, and the number of cyclone separators 200 is the same as the number of air inlet chambers 120. The air inlet 210 of the cyclone unit 230 of each cyclone separator 200 communicates with the corresponding air inlet chamber 120. Dust-laden gas can enter the cyclone unit 230 of the cyclone separator 200 from the air inlet chamber 120 through the air inlet 210, where it undergoes air-dust separation. Dust can then be discharged into the dust collection chamber 110 through the dust exhaust port 220, effectively achieving air-dust separation. Providing at least two cyclone separators 200 effectively improves the efficiency of air-dust separation. At the same time, the dust-laden gas flows around the first axis a, and at least two air inlet cavities 120 can effectively separate the dust-laden gas into different air inlet cavities 120. The dust-laden gas in each air inlet cavity 120 can be separated by the corresponding cyclone separator 200, which can effectively reduce the imbalance of the dust-laden gas entering each cyclone separator 200, thereby improving the gas-dust separation efficiency of the separation mechanism 10.

[0044] In one embodiment, at least two air inlet cavities 120 are evenly distributed around the first axis a. By evenly distributing the air inlet cavities 120, the uniformity of dust-laden gas entering the different air inlet cavities 120 can be effectively improved, thereby further improving the utilization rate of the cyclone separator 200 and the gas-dust separation efficiency.

[0045] Of course, in other embodiments, the air inlet cavity 120 may also be configured according to the distribution characteristics of the dust-laden gas, so that the dust-laden gas can be evenly distributed in different air inlet cavities 120 .

[0046] In this embodiment, there are three cyclone separators 200. The three cyclone separators 200 are evenly distributed around the first axis a. Correspondingly, three air inlet cavities 120 are formed on the dust collection assembly 100, each of which is connected to the air inlet 210 of a cyclone separator 200. The provision of three cyclone separators 200 effectively increases space utilization, reduces the gaps between the cyclone separators 200, and effectively improves the compactness of the structure.

[0047] In other embodiments, the number of cyclone separators 200 may be two, four, five, or other numbers. Correspondingly, the number of air inlet cavities 120 formed may also be two, four, five, or other numbers.

[0048] See also Figure 4 In one embodiment, the cyclone separator 200 includes a plurality of cyclone units 230, which are arranged in a symmetrical structure. The cyclone separator 200 is composed of a plurality of cyclone units 230, and the dust-laden gas can enter different cyclone units 230 through different air inlets 210, which can effectively improve the gas-dust separation efficiency. The plurality of cyclone units 230 are arranged in a symmetrical structure, which can improve the uniformity of the dust-laden gas entering the different cyclone units 230. In this embodiment, the plurality of cyclone units 230 are arranged in a ring structure, which further improves the uniformity of the dust-laden gas entering the different cyclone units 230.

[0049] In this embodiment, the cyclone separator 200 includes six cyclone units 230 arranged in a ring, which effectively improves the compactness of the structure and increases space utilization. In other embodiments, the cyclone separator 200 may include three, four, eight, or other numbers of cyclone units, as long as the dust-laden gas can be directed into different cyclone units 230.

[0050] Specifically, the cyclone unit 230 includes an air inlet 232 and a conical portion 234 disposed on the air inlet 232. A dust exhaust port 220 is provided at one end of the conical portion 234 facing away from the air inlet 232. The air inlet 210 is provided on the sidewall of the air inlet 232. Dust-laden gas enters the cyclone unit 230 through the air inlet 210. Centrifugal force and gravity within the conical portion 234 cause the dust to be discharged through the dust exhaust port 220 on the conical portion 234, thereby separating the dust from the gas.

[0051] Furthermore, the air inlet 210 is formed on a side wall of the air inlet portion 232 , and the opening of the air inlet 210 is tangential to the inner wall of the air inlet portion 232 , thereby enabling the gas entering through the air inlet 210 to effectively rotate within the cyclone unit 230 .

[0052] In this embodiment, a single cyclone separator 200 is composed of an even number of cyclone units 230. The air inlet 210 of one cyclone unit 230 opens tangentially to the inner wall of the air inlet portion 232, forming a left-handed airflow within the cyclone unit 230. The air inlet 210 of another adjacent cyclone unit 230 opens tangentially to the inner wall of the air inlet portion 232, forming a right-handed airflow within the cyclone unit 230. This allows the air inlets 210 of two adjacent cyclone units 230 to share a common wall, simplifying the manufacturing structure and improving processing efficiency.

[0053] In other embodiments, the tangent directions of the air inlets 210 of the plurality of cyclone units 230 and the inner wall of the air inlet portion 232 may also be consistent, and a single cyclone separator 200 may also be composed of an odd number of cyclone units 230 .

[0054] See also Figures 5 to 7 In one embodiment, the cyclone separator 200 further includes an exhaust assembly 240, and the air inlet 232 is opened at one end facing away from the cone 234 to form an exhaust port 236 (eg, Figure 4 As shown, the exhaust assembly 240 is provided with exhaust channels 242 corresponding to the number of cyclone units 230. The exhaust assembly 240 covers the side of the air inlet 232 facing away from the cone 234, and each exhaust channel 242 is inserted into an exhaust port 236. After dust is separated from the dust-laden gas, the clean gas is discharged through the corresponding exhaust channel 242 through the exhaust assembly 240. Furthermore, the provision of the exhaust assembly 240 effectively covers the side of the air inlet 232 facing away from the cone 234, thereby improving the stability of the air intake.

[0055] Specifically, the exhaust assembly 240 includes an exhaust body 244 and an exhaust pipe 246. The exhaust pipe 246 forms an exhaust passage 242. The exhaust body 244 is mounted on the air inlet 232, so that one end of the exhaust pipe 246 passes through the exhaust body 244 and is inserted into the cyclone unit 230 through the exhaust port 236. By forming the exhaust pipe 246 to pass through the cyclone unit 230, it is possible to prevent dust-laden gas from entering the cyclone unit 230 through the air inlet 210 and being discharged directly from the exhaust port 236 without undergoing separation. The exhaust pipe 246 can effectively prevent the discharge of dust-laden gas that has just entered the cyclone unit 230, thereby improving the stability of gas-dust separation.

[0056] In this embodiment, the central axes of the multiple cyclone units 230 of a single cyclone separator 200 are arranged in parallel. Therefore, during processing, the multiple cyclone units 230 of a single cyclone separator 200 can be processed and demolded from the same direction, which can effectively improve processing efficiency and reduce processing costs.

[0057] Specifically, the central axes of the exhaust pipes 246 are arranged parallel to one another. Because the central axes of the multiple cyclone units 230 of a single cyclone separator 200 are arranged parallel to one another, the central axes of the exhaust pipes 246 installed on the cyclone units 230 can also be arranged parallel to one another, effectively improving the processing efficiency of the exhaust assembly 240 and reducing the processing cost of the exhaust assembly 240. In this embodiment, the exhaust pipes 246 are integrally formed with the exhaust body 244, allowing the exhaust pipes 246 to be processed in the same direction.

[0058] In other embodiments, the cone portion 234 of the cyclone unit 230 of a single cyclone separator 200 can also be gathered to form a structure with one end gathering and the other end diverging, which can effectively reduce the size of one end of the single cyclone unit 230 and improve the structural compactness.

[0059] In one embodiment, the cyclone separator 200 further includes an air inlet pipe 250, which forms an air inlet channel 252. A plurality of cyclone units 230 are disposed around the outer periphery of the air inlet pipe 250. The air inlet 210 of each cyclone unit 230 faces and communicates with the air inlet channel 252. The air inlet 210 communicates with the air inlet chamber 120 via the air inlet channel 252. Dust-laden gas enters the air inlet channel 252 of the air inlet pipe 250 from the air inlet chamber 120, thereby converging and guiding the dust-laden gas. Because the air inlets 210 of the cyclone units 230 face the air inlet channel 252, the dust-laden gas within the air inlet channel 252 can be effectively distributed to the plurality of cyclone units 230, effectively improving the uniformity of the dust-laden gas distribution within each cyclone unit 230 and thereby enhancing the efficiency of gas-dust separation.

[0060] Specifically, the multiple cyclone units 230 are evenly distributed around the outer circumference of the air inlet pipe 250, which can further improve the uniformity of the dust-laden gas entering each cyclone unit 230 and further improve the gas-dust separation efficiency.

[0061] In this embodiment, multiple cyclone units 230 are integrally formed on the air inlet pipe 250, which can effectively improve the stability of the connection between the air inlet 210 and the air inlet channel 252 and improve the uniformity of the distribution of dust-laden gas. In other embodiments, multiple cyclone units 230 form an annular structure, and the air inlet pipe 250 can also be inserted into the annular structure.

[0062] See also Figure 2 and Figure 3In one embodiment, the separation mechanism 10 further includes a bracket 300, which is disposed on the dust collection assembly 100. The bracket 300 is formed with a mounting platform 310. The number of mounting platforms 310 corresponds to the number of cyclone separators 200, and each cyclone separator 200 is correspondingly disposed on a mounting platform 310. By providing the bracket 300 and arranging the cyclone separator 200 on the mounting platform 310, effective support is provided for the cyclone separator 200 to be installed on the dust collection assembly 100, thereby facilitating the installation of the cyclone separator 200.

[0063] Specifically, the mounting platform 310 is provided with a plurality of positioning holes 312 and vents 314. The cyclone unit 230 is correspondingly inserted into the positioning holes 312, and the air inlet cavity 120 is connected to the air inlet 210 through the vents 314. When the cyclone unit 230 is installed on the bracket 300, the vents 314 allow dust-laden gas within the air inlet cavity 120 to effectively pass through the vents 314 and enter the air inlet 210 of the cyclone unit 230. Furthermore, since the cyclone unit 230 is inserted into the positioning holes 312, it is convenient for the dust exhaust port 220 to be aligned with the dust collection cavity 110 through the positioning holes 312.

[0064] Furthermore, the cone portion 234 is inserted into the positioning hole 312 so that the dust discharge port 220 can be effectively aligned with the dust collecting chamber 110, facilitating dust collection.

[0065] In one embodiment, the air inlet pipe 250 is located at the vent hole 314, and the air inlet channel 252 is connected to the air inlet cavity 120 through the vent hole 314. The air inlet channel 252 and the air inlet cavity 120 can be effectively connected by providing the vent hole 314.

[0066] In one embodiment, the plane on which the single mounting platform 310 is located forms an acute angle with a plane perpendicular to the first axis a, so that the cyclone separator 200 is clustered near one end of the mounting platform 310. This effectively reduces the size of the bracket 300. Since the bracket 300 is disposed on the dust collection assembly 100, the size of the dust collection assembly 100 can also be effectively reduced, improving the compactness of the structure.

[0067] In other embodiments, different mounting platforms 310 may also be located on the same plane, as long as the mounting support for cyclone separation can be conveniently achieved.

[0068] In one embodiment, the dust collection assembly 100 includes a dust collector 130, which includes a dust collecting portion 131 and at least two partitions 132. The dust collecting chamber 110 is formed on the dust collecting portion 131, and the air inlet chamber 120 is formed on the partitions 132. The at least two partitions 132 are arranged around the first axis a. The partitions 132 facilitate the formation of the air inlet chamber 120, and the dust collecting portion 131 facilitates the formation of the dust collecting chamber 110 for collecting dust.

[0069] Specifically, the air inlet pipe 250 is connected to one end of the partition 132 , thereby facilitating the mutual communication between the air inlet cavity 120 and the air inlet channel 252 , and facilitating the dust-laden gas to enter the cyclone separator 200 .

[0070] Furthermore, the air intake pipe 250 is disposed on one side of the mounting platform 310 , and the partition 132 is disposed on the other side of the mounting platform 310 , so that the partition 132 is connected to the air intake channel 252 through the vent hole 314 on the mounting platform 310 .

[0071] In other embodiments, the air inlet pipe 250 may also be integrally formed on one end of the partition 132 . During installation, the air inlet pipe 250 passes through the vent hole 314 of the bracket 300 and is inserted into the cyclone separator 200 .

[0072] In one embodiment, the dust collector 130 further includes a dust receiving pan 133, which is disposed on the dust collecting portion 131 and has a dust collection port 134 that communicates with the dust collecting chamber 110. The cyclone separator 200 is disposed on the dust receiving pan 133, with the dust discharge port 220 aligned with the dust receiving pan 133. The dust receiving pan 133 effectively expands the dust receiving surface, allowing dust discharged from the dust discharge port 220 to effectively fall into the dust receiving pan 133 and then into the dust collecting chamber 110 through the dust collection port 134.

[0073] Specifically, the surface of the dust collecting pan 133 facing the dust exhaust port 220 is an inwardly concave arc surface, and the dust collecting port 134 is opened at the lowest point of the inwardly concave arc surface, thereby facilitating the dust falling into the dust collecting pan 133 to effectively fall into the dust collecting port 134, thereby avoiding dust accumulation in the dust collecting pan 133.

[0074] Optionally, the cyclone separator 200 is mounted on the dust pan 133 via a bracket 300, which can cover the dust pan 133. Since the cyclone unit 230 is inserted into the positioning hole 312, it can be effectively aligned with the dust pan 133. The bracket 300 covering the dust pan 133 forms a closed dust collection space between the dust pan 133 and the dust collection chamber 110, preventing dust from flying out of the dust collection space and improving dust collection stability.

[0075] In one embodiment, the partition 132 is disposed on the side of the dust receiving pan 133 facing away from the dust collecting portion 131. An air inlet 135 is also provided on the side of the dust receiving pan 133 facing the dust collecting portion 131. The air inlet 135 communicates with the air inlet cavity 120. Since the cyclone separator 200 is disposed on the dust receiving pan 133, disposing the partition 132 on the dust receiving pan 133 facilitates docking between the partition 132 and the air inlet pipe 250. At the same time, since the opening of the air inlet 135 is facing the direction of the dust collecting part 131, the dust-laden gas can enter the air inlet 135 from the outer peripheral side of the dust collecting part 131, and enter the air inlet channel 252 through the air inlet cavity 120, thereby forming an air inlet passage; and the dust falls into the dust collecting tray 133 through the dust exhaust port 220, and further falls into the dust collecting cavity 110 from the dust collecting port 134, thereby forming a dust collecting passage; the partition 132 can effectively separate the air inlet passage and the dust collecting passage, thereby avoiding mutual interference between the air inlet passage and the dust collecting passage.

[0076] Specifically, the air inlet 135 and the dust collecting port 134 are separated from each other to further avoid interference between the formed dust collecting passage and the air inlet passage.

[0077] In one embodiment, the end of the partition 132 facing away from the air inlet pipe 250 is integrally formed on the dust receiving pan 133, which effectively improves the stability of the partition 132 on the dust receiving pan 133 and prevents dust-laden gas from leaking through the gap between the partition 132 and the dust receiving pan 133. In other embodiments, the end of the partition 132 facing away from the air inlet pipe 250 can be directly inserted into the air inlet 135, allowing dust-laden gas to directly enter the air inlet cavity 120.

[0078] In this embodiment, the dust collecting pan 133 is integrally formed on the dust collecting portion 131 , thereby improving the stability of dust falling from the dust collecting pan 133 into the dust collecting chamber 110 and preventing dust from leaking from the gap between the dust collecting pan 133 and the dust collecting portion 131 .

[0079] Please refer again Figure 2 and Figure 3 In one embodiment, the dust collection assembly 100 further includes a filter element 140, which defines a filter chamber 142. The end of the dust collection portion 131 facing away from the cyclone separator 200 extends through the filter chamber 142, and the air inlet chamber 120 communicates with the filter chamber 142. The provision of the filter element 140 effectively filters large dust particles from the dust-laden gas, achieving a primary filtration separation. The dust-laden gas that passes through the filter element 140 enters the cyclone separator 200 from the air inlet chamber 120, enabling secondary gas-dust separation, effectively improving the efficiency of the gas-dust separation.

[0080] In one embodiment, the dust collection assembly 100 further includes a dust cup 150, which has a receiving chamber 152 formed therein. The dust cup 150 has a suction port 154 connected to the receiving chamber 152. The filter element 140 is disposed within the receiving chamber 152. The receiving chamber 152 is connected to the filter chamber 142 via the filter element 140. Dust-laden gas enters the receiving chamber 152 through the suction port 154 of the dust cup 150, is filtered by the filter element 140, and then enters the filter chamber 142. This effectively retains large dust particles within the receiving chamber 152, thereby effectively achieving secondary separation of dust.

[0081] Specifically, the opening direction of the suction port 154 is tangent to the inner wall of the accommodating chamber 152, so that after the dust-laden gas enters the accommodating chamber 152, it can rotate along the inner wall of the accommodating chamber 152, and utilize the effects of centrifugal force and gravity to achieve a certain separation effect, thereby improving the gas-dust separation effect of the separation mechanism 10.

[0082] Furthermore, the suction port 154 is opened at the upper part of the dust cup 150 or near the upper part to prevent the dust-laden gas entering through the suction port 154 from blowing up the dust at the bottom of the accommodating chamber 152 and affecting the gas-dust separation effect of the separation mechanism 10.

[0083] The first axis a in the above embodiment is the central axis of the dust cup 150. Of course, the first axis a can also be the central axis of the dust collecting chamber 110. Specifically, the dust cup 150 and the dust collecting chamber 110 can be coaxially arranged.

[0084] The vacuum cleaner in one embodiment includes the separation mechanism 10 in any of the above embodiments. The dust-laden gas can be filtered in the first stage through the filter element 140, so that larger particles of dust remain in the accommodating cavity 152 of the dust cup 150. The dust-laden gas further enters the air inlet cavity 120 of the partition 132 from the outer peripheral side of the dust collector 130, and enters the air inlet channel 252 of the air inlet pipe 250 through the air vent 314 on the bracket 300. It enters the cyclone unit 230 through the air inlet channel 252 to achieve secondary separation. The coordination between the air inlet cavity 120 and the air inlet channel 252 can not only effectively improve the uniformity of the air intake, but also enable the dust-laden gas to be stably transported to the air inlet 210 of the cyclone unit 230 through the air inlet channel 252, further improving the stability and uniformity of the air intake. The separated dust is discharged into the dust collecting pan 133 through the dust outlet 220 of the cyclone unit 230 and falls into the dust collecting chamber 110 through the dust collecting port 134 to collect the dust. The above vacuum cleaner can effectively achieve the air-dust separation effect and improve the air-dust separation efficiency.

[0085] The above-described embodiments merely represent several embodiments of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
