Description

Technical Field

[0001] The present invention relates to the technical field of dust collection structures, and in particular to a dust collector, a cyclone separation mechanism and a dust collection structure. Background Art

[0002] The principle of a cyclonic vacuum cleaner is to rotate a dust-laden airstream, using centrifugal force to separate dust from the airstream, and then allowing gravity to cause the dust particles to fall. In traditional cyclonic vacuum cleaners, dust-laden air can enter the cyclonic separator through the gap between the dust collecting structure and the outer shell. This results in high wind resistance, poor circulation, and turbulence, which affects the cyclonic vacuum cleaner's dust removal effectiveness. Summary of the Invention

[0003] Based on this, it is necessary to provide a dust collector, a cyclone separation mechanism and a dust collecting structure that can improve the stability of dust-laden gas circulation in order to address the above-mentioned problems.

[0004] A dust collecting structure comprising:

[0005] A dust collecting portion is formed with a dust collecting cavity, and a dust collecting port is opened on the dust collecting portion and communicated with the dust collecting cavity; and

[0006] The air intake part is arranged on one side of the dust collecting part, and the air intake part is formed with an air intake channel. One end of the air intake part is provided with an air inlet connected to the air intake channel, and the other end is provided with an exhaust port connected to the air intake channel. The exhaust port is separated from the dust collecting port.

[0007] When the above-mentioned dust collecting structure is in use, since the air inlet is arranged on one side of the dust collecting part, the exhaust port and the dust collecting port are separated, so that the air inlet at one end of the cyclone separator is connected to the air inlet channel of the air inlet through the exhaust port, and the dust discharge port at the other end of the cyclone separator is connected to the dust collecting chamber through the dust collecting port. The dust-laden gas can enter the air inlet channel from the air inlet at one end of the air inlet, and be discharged into the air inlet of the cyclone separator through the exhaust port at the other end of the air inlet. The dust-laden gas is separated from the gas and dust in the cyclone separator, and the separated dust is collected by passing the dust collecting port and the dust collecting chamber through the dust discharge port. Since the dust-laden gas enters the cyclone separator through the air inlet channel, and then through the air inlet channel, it can provide an effective guiding effect for the circulation of the dust-laden gas, thereby reducing the wind resistance of the dust-laden gas during the circulation process, improving the stability of the dust-laden gas circulation, and effectively reducing the noise during the process.

[0008] In one embodiment, the outer wall of the dust collecting portion is concave toward the air inlet portion to form a groove, and the groove is communicated with the air inlet.

[0009] In one embodiment, the bottom wall of the groove smoothly transitions to the inner wall of the air inlet channel through the air inlet.

[0010] In one embodiment, there are at least two air inlet parts, and at least two of the air inlet parts are arranged around the central axis of the dust collecting part.

[0011] In one embodiment, there are three air inlet parts, and the three air inlet parts are arranged around the central axis of the dust collecting part.

[0012] In one embodiment, the air inlet parts are arranged at intervals around the central axis of the dust collecting part, and the dust collecting port includes at least two dust inlets, at least two of the dust inlets are arranged around the central axis of the dust collecting part, and one dust inlet is arranged between each two adjacent air inlets.

[0013] In one embodiment, the dust collecting port further includes a connecting port, at least two dust inlets are arranged around the connecting port, and the dust inlets are both connected to the connecting port.

[0014] In one embodiment, the dust collecting structure includes a dust receiving pan, which is arranged on a side of the dust collecting portion where a dust collecting port is provided, and the dust collecting port passes through the dust receiving pan.

[0015] In one embodiment, the dust collecting pan is integrally formed on the dust collecting part.

[0016] In one embodiment, the air inlet is arranged on a side of the dust receiving pan facing away from the dust collecting part, and the air inlet passes through a side of the dust receiving pan facing the dust collecting part.

[0017] In one embodiment, one end of the air inlet portion is integrally formed on the dust collecting pan.

[0018] A cyclone separation mechanism, comprising:

[0019] The dust collecting structure as described above; and

[0020] A cyclone separator is provided with an air inlet at one end and a dust exhaust port connected to the air inlet at the other end. The cyclone separator is arranged on the dust collecting structure, and the dust exhaust port is connected to the dust collecting chamber through the dust collecting port; the air inlet of the cyclone separator is connected to the air inlet channel through the exhaust port.

[0021] When the cyclone separator is in use, the cyclone separator is positioned on the dust collection structure due to the separate arrangement of the exhaust port of the air inlet and the dust collection port of the dust collection portion. This allows the air inlet at one end of the cyclone separator to communicate with the air inlet channel of the air inlet via the exhaust port, while the dust discharge port at the other end of the cyclone separator communicates with the dust collection chamber via the dust collection port. Dust-laden gas can enter the air inlet channel from the air inlet at one end of the air inlet and be discharged into the air inlet of the cyclone separator through the exhaust port at the other end of the air inlet. The dust-laden gas undergoes gas-dust separation within the cyclone separator, and the separated dust passes through the dust collection port and the dust collection chamber from the dust discharge port, thereby achieving dust collection. Since the dust-laden gas enters the cyclone separator through the air inlet channel, the air inlet channel effectively guides the flow of the dust-laden gas, reducing the wind resistance of the dust-laden gas during circulation and improving the stability of the dust-laden gas circulation, thereby effectively reducing the noise generated by the cyclone separator during use.

[0022] In one embodiment, the cyclone separator includes a plurality of cyclone units and an air inlet pipe, the air inlet pipe forms an air inlet cavity, and the plurality of cyclone units are arranged around the outer peripheral side of the air inlet pipe. One end of a single cyclone unit is provided with the air inlet, and the other end is provided with the dust exhaust port. The air inlet of each cyclone unit faces the air inlet cavity and is connected to the air inlet cavity, and the exhaust port of the air inlet part is connected to the air inlet cavity.

[0023] A vacuum cleaner comprises the cyclone separation mechanism described above.

[0024] When the above-mentioned vacuum cleaner is in use, the cyclone separator is arranged on the dust collecting structure, so that the air inlet at one end of the cyclone separator is connected to the air inlet channel of the air inlet part through the exhaust port, and the dust outlet at the other end of the cyclone separator is connected to the dust collecting chamber through the dust collecting port. The dust-laden gas can enter the air inlet channel from the air inlet at one end of the air inlet part, and be discharged into the air inlet of the cyclone separator through the exhaust port at the other end of the air inlet part. The dust-laden gas is separated into gas and dust in the cyclone separator, and the separated dust is collected by passing the dust outlet through the dust collecting port and the dust collecting chamber. Since the dust-laden gas enters the cyclone separator through the air inlet channel, the air inlet channel can provide an effective guiding effect for the circulation of the dust-laden gas, thereby reducing the wind resistance of the dust-laden gas during the circulation process and improving the stability of the dust-laden gas circulation. In addition, the noise of the cyclone separation mechanism during use can be effectively reduced, the user experience can be improved, and the dust collection performance of the vacuum cleaner can be improved.

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.

[0035] See also Figure 1 and Figure 2 The cyclone separation mechanism 10 in one embodiment can effectively achieve the effect of gas-dust separation, and at least improve the stability of dust-laden gas circulation, reduce air flow resistance, and reduce noise. Specifically, the cyclone separation mechanism 10 includes a dust collection structure 100 and a cyclone separator 200.

[0036] Please also refer to Figure 3 The dust collecting structure 100 includes a dust collecting part 110 and an air intake part 120. The dust collecting part 110 is formed with a dust collecting chamber 112, and the dust collecting part 110 is provided with a dust collecting port 114 connected to the dust collecting chamber 112; the air intake part 120 is arranged on one side of the dust collecting part 110, and the air intake part 120 is formed with an air intake channel 122. An air inlet 124 connected to the air intake channel 122 is provided at one end of the air intake part 120, and an exhaust port 126 connected to the air intake channel 122 is provided at the other end. The exhaust port 126 is separated from the dust collecting port 114. An air inlet 210 is provided at one end of the cyclone separator 200, and a dust exhaust port 220 connected to the air inlet 210 is provided at the other end. The cyclone separator 200 is arranged on the dust collecting structure 100, and the dust exhaust port 220 is connected to the dust collecting chamber 112 through the dust collecting port 114; the air inlet 210 of the cyclone separator 200 is connected to the air inlet channel 122 through the exhaust port 126.

[0037] When the cyclone separator 10 is in use, the cyclone separator 200 is disposed on the dust collecting structure 100 due to the separate arrangement of the exhaust port 126 of the air inlet 120 and the dust collecting port 114 of the dust collecting portion 110. This allows the air inlet 210 at one end of the cyclone separator 200 to communicate with the air inlet channel 122 of the air inlet 120 through the exhaust port 126, while the dust discharge port 220 at the other end of the cyclone separator 200 communicates with the dust collecting chamber 112 through the dust collecting port 114. Dust-laden gas can enter the air inlet channel 122 through the air inlet 124 at one end of the air inlet 120 and be discharged into the air inlet 210 of the cyclone separator 200 through the exhaust port 126 at the other end of the air inlet 120. The dust-laden gas is separated from the air and dust in the cyclone separator 200, and the separated dust is collected through the dust discharge port 220, the dust collecting port 114, and the dust collecting chamber 112. Since the dust-laden gas enters the cyclone separator 200 through the air inlet channel 122, the air inlet channel 122 can provide effective guidance for the circulation of the dust-laden gas, thereby reducing the wind resistance of the dust-laden gas during the circulation process, improving the stability of the dust-laden gas circulation, and thus effectively reducing the noise of the cyclone separation mechanism 10 during use.

[0038] In one embodiment, the cyclone separator 200 includes multiple cyclone units 230 and an air inlet pipe 240. The air inlet pipe 240 forms an air inlet cavity 242. The multiple cyclone units 230 are arranged around the outer periphery of the air inlet pipe 240. Each cyclone unit 230 has an air inlet 210 at one end and a dust exhaust port 220 at the other end. The air inlet 210 of each cyclone unit 230 faces and communicates with the air inlet cavity 242. The exhaust port 126 of the air inlet portion 120 is communicated with the air inlet cavity 242. Dust-laden gas enters the air inlet cavity 242 of the air inlet pipe 240 through the air inlet channel 122, thereby further converging the dust-laden gas. The air inlet pipe 240 further enhances the guidance of the dust-laden gas. Since the air inlet 210 of the cyclone unit 230 faces the air inlet cavity 242, the dust-laden gas in the air inlet cavity 242 can be effectively distributed to multiple cyclone units 230, effectively improving the uniformity of the distribution of the dust-laden gas entering each cyclone unit 230, thereby improving the gas-dust separation efficiency.

[0039] Specifically, the multiple cyclone units 230 are evenly distributed around the outer circumference of the air inlet pipe 240, which can further improve the uniformity of the dust-laden gas entering each cyclone unit 230 and further improve the gas-dust separation efficiency.

[0040] In this embodiment, multiple cyclone units 230 are integrally formed on the air inlet pipe 240, which can effectively improve the stability of the connection between the air inlet 210 and the air inlet cavity 242 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 240 can also be inserted into the annular structure.

[0041] 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.

[0042] In one embodiment, the cyclone separator 200 further includes an exhaust assembly 250. An outlet 232 is defined at one end of the cyclone unit 230. The exhaust assembly 250 is provided with exhaust channels 252 corresponding to the number of cyclone units 230. The exhaust assembly 250 is disposed at one end of the cyclone separator 200, with each exhaust channel 252 correspondingly inserted into an outlet 232. After dust is separated from the dust-laden gas, the clean gas is discharged through the corresponding exhaust channel 252 via the exhaust assembly 250.

[0043] Specifically, the exhaust assembly 250 includes an exhaust body 254 and an exhaust pipe 256. The exhaust pipe 256 forms an exhaust passage 252. The exhaust body 254 is mounted on one end of the cyclone separator 200, so that one end of the exhaust pipe 256 passes through the exhaust body 254 and is disposed within the cyclone unit 230 through the air outlet 232. By forming the exhaust pipe 256 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 through the air outlet 232 without being separated, thereby improving the stability of the gas-dust separation.

[0044] See also Figure 2 and Figure 3 In one embodiment, there are at least two air inlets 120, which are arranged around the central axis a of the dust collecting section 110. Providing at least two air inlets 120 effectively improves the uniformity of dust-laden gas entering the different air inlet channels 122, thereby further improving the stability of dust-laden gas circulation, reducing noise, and improving gas-dust separation efficiency.

[0045] Specifically, at least two air inlets 120 are evenly arranged around the central axis a of the dust collecting part 110, which can further improve the uniformity of the dust-laden gas entering different air inlet channels 122, further improve the stability of the dust-laden gas circulation, and improve the gas-dust separation efficiency.

[0046] In this embodiment, there are three air inlets 120, which are arranged around the central axis a of the dust collecting section 110. Providing three air inlets 120 can effectively improve space utilization and enhance the compactness of the structure. In other embodiments, the number of air inlets 120 can also be two, four, five, or other numbers.

[0047] In this embodiment, the number of cyclone separators 200 corresponds to the number of air inlets 120. Each cyclone separator 200 corresponds to one air inlet 120, effectively improving the gas-dust separation efficiency. Furthermore, the dust-laden gas within each air inlet channel 122 can be separated by the corresponding cyclone separator 200, effectively ensuring uniform distribution of the dust-laden gas and thereby improving the gas-dust separation efficiency.

[0048] In other embodiments, the number of the cyclone separator 200 may also be one, and the air inlet channels 122 of the different air inlet parts 120 are all connected to the air inlet 210 of the cyclone separator 200 .

[0049] See also Figure 4 In one embodiment, the outer wall of the dust collecting portion 110 facing the air inlet portion 120 is recessed to form a groove 116, which is connected to the air inlet 124. By forming the groove 116 on the outer wall of the dust collecting portion 110, dust-laden gas can be effectively collected in the groove 116 and effectively pass through the air inlet 124 through the groove 116 into the air inlet passage 122, thereby improving the efficiency of dust-laden gas entering the air inlet passage 122.

[0050] Specifically, the bottom wall of the groove 116 smoothly transitions to the inner wall of the air inlet channel 122 through the air inlet 124, which can effectively reduce the stability of the dust-laden gas entering the air inlet channel 122 from the groove 116 through the air inlet 124, reduce wind resistance, and reduce noise generation.

[0051] In this embodiment, the portion of the dust collecting portion 110 that forms the bottom wall of the groove 116 extends to form a portion of the air inlet portion 120. This portion is the portion where the bottom wall of the groove 116 smoothly transitions to the inner wall of the air inlet passage 122, allowing the air inlet portion 120 and a portion of the dust collecting portion 110 to share a common wall. This makes the dust collecting structure 100 more compact and easier to manufacture. Of course, in other embodiments, the dust collecting portion 110 and the air inlet portion 120 may not share a common wall.

[0052] See also Figure 5 In one embodiment, the air inlet sections 120 are spaced apart around the central axis a of the dust collecting section 110. The dust collecting port 114 includes at least two dust inlets 113. The at least two dust inlets 113 are arranged around the central axis a of the dust collecting section 110, with one dust inlet 113 positioned between each pair of adjacent air inlets 120. Providing a dust inlet 113 between each pair of adjacent air inlets 120 effectively increases the size of the dust collecting port 114, allowing dust discharged from the dust outlet 220 to effectively pass through the dust collecting port 114 and fall into the dust collecting chamber 112, thereby improving dust collection efficiency.

[0053] Specifically, the dust collection port 114 further includes a communication port 115, and at least two dust inlets 113 are arranged around the communication port 115, and the dust inlets 113 are all connected to the communication port 115. Connecting different dust inlets 113 through the communication port 115 can further improve the efficiency and stability of dust collection, so that dust can effectively fall into the dust collection chamber 112.

[0054] See also Figures 3 to 5 In one embodiment, the dust collecting structure 100 includes a dust collecting pan 130, which is disposed on one side of the dust collecting portion 110 where the dust collecting port 114 is located. The dust collecting port 114 extends through the dust collecting pan 130. The dust collecting pan 130 can effectively expand the dust collecting area and further improve the dust collecting stability.

[0055] Specifically, the surface of the dust collecting pan 130 facing away from the dust collecting part 110 is a concave arc surface, and the dust collecting port 114 is located at the lowest point of the concave arc surface, thereby facilitating the dust falling into the dust collecting pan 130 to effectively fall into the dust collecting port 114, thereby avoiding dust accumulation in the dust collecting pan 130.

[0056] In one embodiment, the air intake 120 is disposed on the side of the dust receiving pan 130 facing away from the dust collecting section 110, and the air inlet 124 extends through the side of the dust receiving pan 130 facing the dust collecting section 110. Positioning the air intake 120 on the dust receiving pan 130 facilitates docking between the air intake 120 and the air inlet pipe 240. Furthermore, because the opening of the air inlet 124 faces the dust collecting section 110, dust-laden gas can enter the air inlet 124 from the outer periphery of the dust collecting section 110 and enter the air inlet cavity 242 through the air inlet passage 122, thereby forming an air intake passage. Dust, on the other hand, falls into the dust receiving pan 130 through the dust discharge port 220 and further into the dust collecting cavity 112 through the dust collecting port 114, thereby forming a dust collection passage. The air intake 120 effectively separates the air intake passage from the dust collection passage, preventing interference between the two passages.

[0057] In this embodiment, the dust receiving pan 130 is integrally formed on the dust collecting portion 110, which can improve the stability of dust falling from the dust receiving pan 130 into the dust collecting chamber 112 and prevent dust from leaking through the gap between the dust receiving pan 130 and the dust collecting portion 1101. In other embodiments, the dust receiving pan 130 can also be provided on the dust collecting portion 110 by welding or gluing.

[0058] In this embodiment, one end of the air inlet portion 120 is integrally formed with the dust receiving pan 130, which effectively improves the stability of the air inlet portion 120 on the dust receiving pan 130 and prevents dust-laden gas from leaking through the gap between the air inlet portion 120 and the dust receiving pan 130. In other embodiments, the air inlet portion 120 can also be directly installed on the dust receiving pan 130, allowing dust-laden gas to directly enter the air inlet cavity 242 through the air inlet 124.

[0059] Please refer again Figure 1 In one embodiment, the cyclone separation mechanism 10 further includes a bracket 300. The bracket 300 is disposed on a side of the dust collecting portion 110 where the dust collecting port 114 is located. The bracket 300 is formed with a mounting platform 310, and the cyclone separator 200 is correspondingly mounted on the mounting platform 310. The bracket 300 facilitates the installation of the cyclone separator 200 and provides support for the cyclone separator 200 when mounted on the dust collecting structure 100.

[0060] Optionally, the cyclone separator 200 is arranged on the dust collecting pan 130 through the bracket 300, and the bracket 300 can cover the dust collecting pan 130. The dust collecting pan 130 and the dust collecting chamber 112 form a closed dust collecting space, preventing dust from flying out of the dust collecting space and improving the stability of dust collection.

[0061] In one embodiment, the number of the mounting platforms 310 corresponds to the number of the cyclone separators 200 , and each cyclone separator 200 is correspondingly disposed on a mounting platform 310 , thereby providing effective mounting support for each cyclone separator 200 .

[0062] In one embodiment, the mounting platform 310 is provided with a plurality of positioning holes 312 and ventilation holes 314. The end of the cyclone unit 230, provided with the dust exhaust port 220, is correspondingly inserted into the positioning hole 312. The air inlet cavity 242 communicates with the air inlet cavity 242 through the ventilation holes 314. The ventilation holes 314 allow dust-laden gas within the air inlet channel 122 to effectively pass through the air inlet cavity 242 and enter the air inlet 210 of the cyclone unit 230. Furthermore, because the cyclone unit 230 is inserted into the positioning hole 312, the dust exhaust port 220 can be easily aligned with the dust collection port 114 through the positioning hole 312.

[0063] In one embodiment, an angle is formed between the plane on which the single mounting platform 310 is located and a plane perpendicular to the central axis aa of the dust collecting structure 100, 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, and thus the size of the dust collecting structure 100, improving the compactness of the structure.

[0064] 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.

[0065] In one embodiment, the bracket 300 further includes a support portion 320, which is disposed on a side of the mounting platform 310 facing away from the dust collection structure. The support portion 320 and the mounting platform 310 form a mounting cavity for accommodating the cyclone separator 200. The support portion 320 effectively supports and protects the cyclone separator 200, improving the stability of the cyclone separator 200 when mounted on the mounting platform 310.

[0066] In one embodiment, the cyclone separation mechanism 10 further includes a filter element 400, which defines a filter chamber 410. The end of the dust collecting portion 110, facing away from the cyclone separator 200, extends through the filter chamber 410, and the air inlet passage 122 communicates with the filter chamber 410. The filter element 400 effectively filters large dust particles from the dust-laden gas, achieving primary filtration and separation. The dust-laden gas that passes through the filter element 400 enters the cyclone separator 200 through the air inlet passage 122, enabling secondary gas-dust separation, effectively improving gas-dust separation efficiency.

[0067] In one embodiment, the cyclone separation mechanism 10 further includes a dust cup 500, which has a receiving chamber 510 formed therein. The dust cup 500 has a suction port 520 connected to the receiving chamber 510. The filter element 400 is disposed within the receiving chamber 510. The receiving chamber 510 is connected to the filter chamber 410 via the filter element 400. Dust-laden gas enters the receiving chamber 510 through the suction port 520 of the dust cup 500, is filtered by the filter element 400, and then enters the filter chamber 410. This effectively retains large dust particles within the receiving chamber 510, thereby effectively achieving secondary separation of dust.

[0068] The vacuum cleaner in one embodiment includes the cyclone separation mechanism 10 in any of the above-mentioned embodiments. The dust-laden gas can be filtered through the filter element 400 to achieve primary filtration, so that larger dust particles remain in the accommodating chamber 510 of the dust cup 500. The dust-laden gas further enters the air inlet channel 122 of the air inlet portion 120 from the outer peripheral side of the dust collecting structure 100, and enters the air inlet cavity 242 of the air inlet pipe 240 through the air vent 314 on the bracket 300. From the air inlet cavity 242, it enters the cyclone unit 230 to achieve secondary separation. The coordination between the air inlet channel 122 and the air inlet cavity 242 can effectively improve the stability and uniformity of the air intake and reduce the noise during use. The separated dust is discharged from the dust outlet 220 of the cyclone unit 230 into the dust receiving tray 130, and falls into the dust collecting cavity 112 through the dust collecting port 114, thereby achieving dust collection. The above-mentioned vacuum cleaner can effectively achieve the effect of gas-dust separation and improve the efficiency of gas-dust separation.
