Description

Technical Field

[0001] The present application relates to the technical field of environmental cleaning appliances, and in particular to an air duct structure, cleaning equipment and a cleaning system. Background Art

[0002] Cleaning equipment (such as vacuum cleaners, floor scrubbers, etc.) can suck dust and dirt from the ground to keep the ground clean.

[0003] In related technologies, a cleaning system includes a base station and a cleaning device, which includes a motor assembly, an air duct structure, and a dust cup assembly. The motor assembly is connected to the dust cup assembly through the air duct structure, so that dust and dirt are sucked into the dust cup assembly through the air duct structure. Once the dust cup assembly is full, the cleaning device needs to be placed on the base station, so that the base station can automatically suck the dust and dirt in the dust cup assembly into the base station's dust bag, completing the dust collection.

[0004] However, the corresponding structure of the base station's self-dust collection is relatively complex and the cost is relatively high. Utility Model Content

The rotating assembly is rotatably connected to the connector, so that the rotating assembly rotates relative to the connector and switches between the first state and the second state, corresponding to opening and closing different air ducts. By rotating the rotating assembly, the motor assembly can be made to suck or blow air relative to the dust cup assembly without changing the motor assembly. When the dust cup assembly is connected to the base station (or other dust collecting devices, equipment, etc. with a dust collecting space), the dust can be automatically discharged into the base station under the blowing action of the motor assembly.

[0070] In related technologies, a cleaning system includes a base station and a cleaning device, which includes a motor assembly, an air duct structure, and a dust cup assembly. The motor assembly is connected to the dust cup assembly through the air duct structure, so that dust and dirt are sucked into the dust cup assembly through the air duct structure. Once the dust cup assembly is full, the cleaning device needs to be placed on the base station, so that the base station can automatically suck the dust and dirt in the dust cup assembly into the base station's dust bag, completing the dust collection.

[0071] However, the corresponding structure of the base station's self-dust collection is relatively complex and the cost is relatively high.

[0072] In view of the above problems, the embodiments of the present application provide an air duct structure, a cleaning device and a cleaning system. The air duct structure is provided by providing a connecting member and a rotating assembly. The connecting member has an air duct, and the air duct has a first air duct, a second air duct and a third air duct. The rotating assembly is rotatably connected to the connecting member, so that the rotating assembly rotates relative to the connecting member and switches between a first state and a second state. By rotating the rotating assembly, the motor assembly inhales or blows air relative to the dust cup assembly without changing the motor assembly. Under the action of the blowing, the dust cup assembly can discharge the dust into the dust collecting part by itself. There is no need to provide an additional motor device in the dust collecting part such as the base station to absorb the dust, making the dust collection operation of the cleaning device and the cleaning system more convenient and quick, simplifying the structure of the cleaning device and the cleaning system, and reducing the cost of setting up the corresponding motor device.

[0073] The following will be combined with the Figure 1 To the attached Figure 12 The specific implementation methods of the air duct structure, cleaning equipment and cleaning system provided in the embodiments of the present application are described in detail.

[0074] Reference Figures 1 to 6As shown, an embodiment of the present application provides an air duct structure for a cleaning device, the air duct structure including: a connecting member 100, on which an air duct group for communicating with a motor assembly 300 of the cleaning device is provided, the air duct group having a first air duct 142, a second air duct 131 and a third air duct 132.

[0075] The rotating assembly 200 is partially inserted into the connecting member 100 .

[0076] The rotating assembly 200 is configured to rotate relative to the connecting member 100 to switch between a first state and a second state. In the first state, the rotating assembly 200 closes the second air duct 131 and the third air duct 132 so that the first air duct 142 connects the air inlet of the motor assembly 300 and the dust cup assembly 500 of the cleaning device.

[0077] In the second state, the rotating assembly 200 closes the first air duct 142 and opens the second air duct 131 and the third air duct 132, so that the air outlet of the motor assembly 300 is connected to the dust cup assembly 500 through the third air duct 132, and the air inlet of the motor assembly 300 is connected to the outside world through the second air duct 131.

[0078] The second air duct 131 is configured to, when connected to the outside, blow external gas into the dust cup assembly 500 through the motor assembly 300 and the third air duct 132, so that the base station 600 connected to the dust cup assembly 500 collects dust and exhaust.

[0079] It should be noted here that Figure 2 The dotted arrows in the figure indicate the air flow path in the air duct structure and the motor assembly 300 in the first state. Figure 5 The dotted arrows in the figure indicate the air flow path within the air duct structure, the motor assembly 300, the dust cup assembly 500 and the base station 600 in the second state.

[0080] The connector 100 is connected to the motor assembly 300 of the cleaning device so that the air duct of the connector 100 is connected to the motor assembly 300. The connector 100 is also connected to the dust cup assembly 500. When the motor assembly 300 is running, the air can be driven to flow in the dust cup assembly 500 through the air duct group.

[0081] The rotating assembly 200 is partially inserted into the connecting member 100, so that part of the rotating assembly 200 is located outside the connecting member 100, and part of the rotating assembly 200 is located inside the connecting member 100 and is rotatably connected to the rotating assembly 200. In a specific implementation, the connecting member 100 can be relatively fixedly connected to the motor assembly 300 or the dust cup assembly 500, and the rotating assembly 200 rotates relative to the connecting member 100, the motor assembly 300 and the dust cup assembly 500. Alternatively, the rotating assembly 200 can be relatively fixedly connected to the motor assembly 300 or the dust cup assembly 500, and the connecting member 100 rotates relative to the rotating assembly 200, the motor assembly 300 and the dust cup assembly 500. This application does not limit this. The air duct structure of the embodiment of the present application is described below using the former case as an example.

[0082] Therefore, when the rotating assembly 200 rotates relative to the connecting member 100, the rotating assembly 200 can cooperate with the connecting member 100 from the inside and the outside of the connecting member 100 respectively, so that the rotating assembly 200 switches between the first state and the second state.

[0083] Among them, the air duct group has a first air duct 142, a second air duct 131 and a third air duct 132. The first air duct 142 and the second air duct 131 are both configured to be connected to the air inlet of the motor assembly 300, and the third air duct 132 is configured to be connected to the air outlet of the motor assembly 300. In addition, the first air duct 142 and the third air duct 132 are also connected to the dust cup assembly 500, while the second air duct 131 is connected to the outside world.

[0084] When the rotating assembly 200 rotates to the first state relative to the connecting member 100, the rotating assembly 200 closes the second air duct 131 and the third air duct 132, and opens the first air duct 142, so that when the motor assembly 300 is running, it can suck air into the dust cup assembly 500 through the first air duct 142, discharge the sucked gas to the outside, and form a negative pressure in the dust cup assembly 500, so that dust can be sucked into the dust cup assembly 500, thereby realizing the dust collection operation.

[0085] When the rotating component 200 rotates to the second state relative to the connecting member 100, the rotating component 200 opens the second air duct 131 and the third air duct 132, and closes the first air duct 142, so that when the motor component 300 is running, it can inhale air from the outside through the second air duct 131, and blow the inhaled gas into the dust cup component 500 through the third air duct 132, so that a positive pressure is formed in the dust cup component 500, so that dust can be discharged from the dust cup component 500 together with the gas blown into the dust cup component 500. When the dust cup component 500 is connected to a base station 600 (or other devices or equipment with a dust collection function), the dust can be discharged into the base station 600 by itself, and the base station 600 is exhausted through the exhaust hole, thereby completing the self-dust collection operation of the base station 600, and there is no need to set a motor device for sucking dust at the base station 600.

[0086] Therefore, the air duct structure provided by the embodiment of the present application is provided with a connecting member 100 and a rotating assembly 200. The connecting member 100 has an air duct group, and the air duct group has a first air duct 142, a second air duct 131, and a third air duct 132. The rotating assembly 200 is rotatably connected to the connecting member 100, so that the rotating assembly 200 rotates relative to the connecting member 100 and switches between a first state and a second state. In the first state, the rotating assembly 200 closes the second air duct 131 and the third air duct 132 and opens the first air duct 142, so that the motor assembly 300 can suck dust into the dust cup assembly 500 through the first air duct 142. In the second state, the rotating assembly 200 closes the first air duct 142 and opens the second air duct 131 and the third air duct 132, so that the motor assembly 300 can suck external air through the second air duct 131 and blow the air into the dust cup assembly 500 through the third air duct 132, so that the dust in the dust cup assembly 500 is discharged.

[0087] Through the air duct structure provided in the embodiment of the present application, the motor assembly 300 can be rotated to achieve suction or blowing relative to the dust cup assembly 500 without changing the motor assembly 300. When the dust cup assembly 500 is connected to the base station 600 (or other dust collection devices, equipment, etc. with a dust collection space), the dust can be discharged into the base station 600 automatically under the blowing action of the motor assembly 300. There is no need to set up an additional motor device at the base station 600 to absorb the dust, making the dust collection operation of the cleaning equipment and the cleaning system more convenient and quick, and simplifying the structure of the cleaning equipment and the cleaning system, reducing the cost of setting up the corresponding motor device.

[0088] Reference Figures 1 to 6 ,and Figure 8 As shown, in some embodiments, the rotating assembly 200 includes a driving member 210 , which is rotatably connected to the connecting member 100 .

[0089] The driving member 210 is configured to rotate relative to the connecting member 100 to switch between a first state and a second state.

[0090] In the first state, the driving member 210 closes the third air duct 132 and opens the first air duct 142 .

[0091] In the second state, the driving member 210 opens the third air passage 132 and closes the first air passage 142 .

[0092] The driving member 210 is rotatably disposed on the outside of the connecting member 100 so that when it rotates relative to the connecting member 100, it can correspondingly close or open the third air duct 132 and the first air duct 142. When the driving member 210 opens the first air duct 142, it simultaneously closes the third air duct 132, and when it opens the third air duct 132, it simultaneously closes the first air duct 142. That is, the driving member 210 can only open one of the first and third air ducts 142, 132, and close the other, but not open both the first and third air ducts 142, 132 at the same time, to prevent the motor assembly 300 from failing to effectively collect or exhaust dust during operation.

[0093] In some embodiments, a push rod 214 is provided on the driving member 210, and force can be manually applied to the push rod 214 to rotate the driving member 210 relative to the connecting member 100, or a corresponding driving structure is provided on some base stations 600. When the cleaning equipment is connected to the base station 600, the corresponding driving structure will drive the driving member 210 to rotate. This application does not impose any restrictions on this.

[0094] Reference Figures 1 to 6 ,and Figure 8 As shown, the rotating assembly 200 further includes a driven member 220 . The driven member 220 is located in the connecting member 100 and is connected to the driving member 210 .

[0095] In the first state, the follower 220 closes the second air duct 131 , and in the second state, the follower 220 opens the second air duct 131 .

[0096] The follower 220 is arranged in the connecting member 100 and connected to the driving member 210, so that the follower 220 and the driving member 210 are respectively located on the inner and outer sides of the connecting member 100, ensuring the stability of the connection between the rotating component 200 and the connecting member 100, and the smooth rotation of the rotating component 200 relative to the connecting member 100.

[0097] The follower 220 can rotate synchronously with the driving member 210, so as to close the second air duct 131 when the driving member 210 closes the third air duct 132 and opens the first air duct 142, or open the second air duct 131 when the driving member 210 closes the first air duct 142 and opens the third air duct 132, so as to ensure that the motor assembly 300 can smoothly enable the dust cup assembly 500 to absorb or discharge dust.

[0098] In some embodiments, reference Figure 3 、 Figure 6 and Figure 8 As shown, the driving member 210 includes a first driving portion 211 and a second driving portion 212 . The first driving portion 211 is disposed on the second driving portion 212 , and the second driving portion 212 is connected to the connecting member 100 .

[0099] In the first state, the first driving unit 211 closes the third air duct 132 , and the second driving unit 212 opens the first air duct 142 .

[0100] In the second state, the first driving unit 211 opens the third air duct 132 , and the second driving unit 212 closes the first air duct 142 .

[0101] The second drive unit 212 is connected to the connector 100 to drive the first drive unit 210 to rotate relative to the connector 100. Furthermore, the first drive unit 211 can close or open the third air duct 132 as it rotates, and the second drive unit 212 can correspondingly open or close the first air duct 142. The first drive unit 211 and the second drive unit 212 alternately open the corresponding third air duct 132 or first air duct 142 to ensure that the dust cup assembly 500 can smoothly absorb or discharge dust.

[0102] When implementing it, refer to Figure 3 、 Figure 6 and Figure 8 As shown, the first driving portion 211 defines a first air outlet 2111 , and the second driving portion 212 defines a second air outlet 2121 .

[0103] In the first state, the first air outlet 2111 and the third air channel 132 are interlaced to close the third air channel 132 , and the second air outlet 2121 and the first air channel 142 are opposite to each other to open the first air channel 142 .

[0104] In the second state, the first air outlet 2111 is opposite to the third air passage 132 to open the third air passage 132 , and the second air outlet 2121 is interlaced with the first air passage 142 to close the first air passage 142 .

[0105] It can be understood that by opening the first air outlet 2111 on the first driving part 211 and the second air outlet 2121 on the second driving part 212, the first driving part 211 and the second driving part 212 can open and close the third air duct 132 and the first air duct 142 through their respective air outlets.

[0106] For example, when the first driving unit 211 rotates so that the first air outlet 2111 is opposite and connected to the third air duct 132, the third air duct 132 is unobstructed, that is, the third air duct 132 is open. When the second driving unit 212 rotates so that the second air outlet 2121 is opposite and connected to the first air duct 142, the first air duct 142 is unobstructed, that is, the first air duct 142 is open. When the first driving unit 211 rotates so that the first air outlet 2111 is offset from the third air duct 132, other parts of the first driving unit 211 will block the third air duct 132, thereby closing the third air duct 132. Similarly, when the second driving unit 212 rotates so that the second air outlet 2121 is offset from the first air duct 142, other parts of the second driving unit 212 will block the first air duct 142, thereby closing the first air duct 142.

[0107] In some embodiments, reference Figure 3 、 Figure 6 and Figure 8 As shown, the first driving part 211 is coaxially wound on the second driving part 212 , a plurality of first air outlets 2111 are sequentially spaced along the circumference of the first driving part 211 , and a plurality of second air outlets 2121 are sequentially spaced along the circumference of the second driving part 212 .

[0108] It can be understood that the first air outlet 2111 and the second air outlet 2121 are arranged in sequence along the circumference of the corresponding driving part, which can facilitate the formation of multiple air outlet structures on the corresponding first driving part 211 and the second driving part 212. Only a small rotation of the driving part 210 is required to connect the first air outlet 2111 with the third air duct 132 and the second air outlet 2121 with the first air duct 142, thereby improving the switching rate of the rotating component 200 between the first state and the second state, thereby improving the convenience of the dust collection and dust removal operations of the cleaning equipment.

[0109] In other embodiments, a larger first air outlet 2111 may be opened on one side of the first driving portion 211, and a larger second air outlet 2121 may be opened on one side of the second driving portion 212, and the third air duct 132 and the first air duct 142 may be set accordingly, so that when the first air outlet 2111 is connected to the third air duct 132, or when the second air outlet 2121 is connected to the first air duct 142, the air duct structure can have a larger air volume.

[0110] Reference Figure 3 、 Figure 6 and Figure 8 As shown, the first air outlet 2111 and the second air outlet 2121 are alternately arranged along the radial direction of the second driving part 212 .

[0111] It is understood that by staggering the first air vents 2111 and the second air vents 2121 along the radial direction of the second driving portion 212, the first air vents 2111 and the second air vents 2121 are staggered on the driving member 210, rather than being arranged one-to-one along the radial direction of the second driving portion 212. This arrangement can enhance the overall structural strength of the driving member 210, making the driving member 210 more stable and reducing deformation of the driving member 210 during rotation.

[0112] In some embodiments, reference Figure 1 、 Figure 4 and Figure 8 As shown, the follower 220 includes a first follower portion 221 , and the first follower portion 221 has a third air port 2211 .

[0113] In the first state, the third air outlet 2211 and the second air duct 131 are interlaced to close the second air duct 131 . In the second state, the third air outlet 2211 and the second air duct 131 are opposite to each other to open the second air duct 131 .

[0114] The first follower part 221 is connected to the driving member 210, so that the driving member 210 can drive the first follower part 221 to rotate synchronously, and as the first follower part 221 rotates, when the driving member 210 closes the third air duct 132 and opens the first air duct 142, the first follower part 221 can close the second air duct 131 together to prevent air flow from entering from the second air duct 131, thereby reducing the suction force of the motor assembly 300 on the dust cup assembly 500, and when the driving member 210 closes the first air duct 142 and opens the third air duct 132, the first follower part 221 can open the second air duct 131 accordingly, so that the air flow can smoothly enter from the second air duct 131, and be discharged from the third air duct 132 after passing through the motor assembly 300, thereby ensuring that the dust cup assembly 500 can discharge dust smoothly.

[0115] Specifically, the first driven portion 221 is provided with a third air port 2211 corresponding to the second air duct 131. Referring to the arrangement of the first air port 2111 and the second air port 2121, it is easy to understand that when the third air port 2211 is opposite the second air duct 131, the third air port 2211 can communicate with the second air duct 131, leaving the second air duct 131 unobstructed and allowing air to flow smoothly. However, when the third air port 2211 rotates to intersect with the second air duct 131, the second air duct 131 is blocked by other parts of the first driven portion 221, thereby blocking the second air duct 131 and preventing airflow.

[0116] Further, refer to Figure 1 、 Figure 4 and Figure 8 As shown, the follower 220 further includes a second follower portion 222 , the second follower portion 222 is connected to the driving member 210 , and the first follower portion 221 is disposed on the second follower portion 222 .

[0117] The second driven portion 222 is provided with a fourth air port 2221 . In the first state, the fourth air port 2221 is opposite to the first air duct 142 to open the first air duct 142 . In the second state, the fourth air port 2221 intersects with the first air duct 142 to close the first air duct 142 .

[0118] The first driven portion 221 is disposed on the second driven portion 222 , so that the first driven portion 221 is connected to the driving member 210 through the second driven portion 222 , ensuring that the driving member 210 stably drives the second driven portion 222 to rotate.

[0119] In order to prevent the second driven part 222 from affecting the smooth air flow of the first air duct 142 and not interfering with the second air outlet 2121 opening or closing the first air duct 142, a fourth air outlet 2221 is also provided on the second driven part 222, so that the fourth air outlet 2221 can correspond one-to-one with the second air outlet 2121, thereby realizing the corresponding setting of the fourth air outlet 2221 and the first air duct 142.

[0120] Therefore, when the second air outlet 2121 is connected to the first air duct 142, the second air outlet 2121 can also be connected to the first air duct 142, ensuring that the airflow can stably enter through the first air duct 142, and when the second driving part 212 closes the first air duct 142, the second driven part 222 also closes the first air duct 142 to improve the closing effect of the first air duct 142.

[0121] It should be noted here that the second driven part 222 can also be set as a connecting rod, or a connecting structure with a dense mesh, that is, it can connect the first driven part 221 and the driving component without opening or closing the first air duct 142. This application does not impose any restrictions on this.

[0122] In specific implementation, refer to Figure 8 As shown, the first driven portion 221 is disposed around the circumference of the second driven portion 222 and extends along the axial direction of the second driven portion 222 .

[0123] In this way, the first air duct 142 and the third air duct 132 are correspondingly arranged on the same side of the connector 100, so that the first air duct 142 and the third air duct 132 are connected to the dust cup assembly 500 at the same time, and the second air duct 131 is arranged on the other side of the connector 100 different from the side where the third air duct 132 is located, so as to prevent the second air duct 131 and the first air duct 142 from interfering with each other, thereby simplifying the air duct structure of the connector 100 and simplifying the distribution structure of the first air duct 142, the second air duct 131 and the third air duct 132.

[0124] And, refer to Figure 7 and Figure 8As shown, the connecting member 100 is provided with a first mounting portion 141 , the driving member 210 is provided with a second mounting portion 213 adapted to the first mounting portion 141 , the second mounting portion 213 is rotationally connected to the first mounting portion 141 , and the driven member 220 is connected to the second mounting portion 213 .

[0125] A first mounting portion 141 is provided on the connecting member 100, and a second mounting portion 213 is provided on the driving member 210. The second mounting portion 213 is passed through the first mounting portion 141 and partially extends out of the first mounting portion 141 so as to be located inside the connecting member 100, so as to facilitate the connection between the driven member 220 and the second mounting portion 213 on the inner side of the connecting member 100, thereby realizing that the driven member 220 is stably located inside the connecting member 100 and rotates with the driving member 210.

[0126] Specifically, refer to Figure 7 As shown, the first mounting portion 141 is a through hole, the second mounting portion 213 is a spline shaft, and the driven member 220 is provided with a spline groove adapted to the spline shaft.

[0127] It is understandable that the second mounting portion 213 can be coaxially disposed on the second driving portion 212 and connected to the second driven portion 222 to ensure that the rotating assembly 200 continuously and stably rotates around its own central axis.

[0128] The first mounting portion 141 is configured as a through-hole, the second mounting portion 213 is configured as a spline shaft, and a through-hole corresponding to the spline shaft is provided on the second driven portion 222. The through-hole is provided with a spline groove for plugging into the spline shaft. This spline connection structure provides the rotating assembly 200 with a good load-bearing capacity, and the connection between the driven member 220 and the driving member 210 relative to the connector 100 is highly reliable, ensuring stable rotation of the driving member 210 and the driven member 220.

[0129] Of course, in other embodiments, the second mounting portion 213 may be provided with other anti-rotation connection structures, such as a flat key shaft, and the second driven portion 222 may be provided with a corresponding anti-rotation fitting hole, so that the second mounting portion 213 and the second driven portion 222 are anti-rotationally connected. This application does not impose any restrictions on this.

[0130] In some embodiments, reference Figure 7 As shown, the rotating assembly 200 further includes a stopping member 230 . The stopping member 230 is sleeved on the second mounting portion 213 and abuts against the driven member 220 .

[0131] By clamping the stopping member 230 on the second mounting portion 213, the stopping member 230 is located on the side of the follower 220 away from the driving member 210 and abuts against the follower 220, so that the stopping member 230 can stop the follower 220 and prevent the follower 220 from moving axially along the second mounting portion 213, so as to ensure the tightness of the follower 220 and the driving member 210 in closing the first air duct 142, the second air duct 131 and the third air duct 132.

[0132] Among them, the stopping member 230 can be a clamping ring with an opening on one side, and a clamping slot is provided on the second mounting portion 213. The clamping ring is clamped in the clamping slot through the opening to be clamped with the second mounting portion 213, and one side of the clamping ring is pressed against the side of the follower 220 away from the driving member 210.

[0133] In some embodiments, reference Figures 1 to 6 ,and Figures 8 to 12 As shown, the connecting member 100 includes a first ring body 110 and a second ring body 120 , and the first ring body 110 is located inside the second ring body 120 .

[0134] At least two connecting parts 130 are disposed between the first ring body 110 and the second ring body 120 at intervals and connected to the first ring body 110 and the second ring body 120 .

[0135] A second air duct 131 is formed between two adjacent connecting portions 130 . A third air duct 132 is provided on the connecting portion 130 , and two ends of the third air duct 132 are respectively communicated with the first ring body 110 and the second ring body 120 .

[0136] The first ring body 110 and the second ring body 120 are coaxially arranged, and a spacing space can be formed between the first ring body 110 and the second ring body 120 for the connecting part 130 to be arranged in the spacing space, so that the connecting part 130, the first ring body 110 and the second ring body 120 together form the second air duct 131 and the third air duct 132.

[0137] This arrangement allows the connector 100 to be structurally compatible with the rotating assembly 200, increases the airflow through the air duct formed by the connector 100, and makes the overall structure of the connector 100 more compact. The follower 220 is located inside the first ring 110, and the driver 210 is located on the same side of the first ring 110, the second ring 120, and the connecting portion 130.

[0138] In specific implementation, the connecting part 130 has a connecting cavity, and openings are provided on the first ring body 110 and the second ring body 120. The opening on the second ring body 120 is connected with the opening on the first ring body 110 through the connecting cavity to form a second air duct 131; the two adjacent connecting parts 130, and the part of the first ring body 110 and the part of the second ring body 120 located between the two connecting parts 130, together form a third air duct 132.

[0139] The connecting portion 130 may be a hollow tubular structure, such as a rectangular tube or a circular tube, so that a connecting cavity is naturally formed inside the hollow tubular structure. The openings on the first ring body 110 and the second ring body 120 are arranged in a one-to-one correspondence and are adapted to the shape of the connecting portion 130. The connecting portion 130 is disposed between the first ring body 110 and the second ring body 120, and the two ends of the connecting portion 130 are respectively connected to the openings on the first ring body 110 and the second ring body 120, so that the connecting cavity of the connecting portion 130 communicates with the openings on the first ring body 110 and the second ring body 120, so that the inner side of the first ring body 110 and the outer side of the second ring body 120 are connected in sequence through the opening of the first ring body 110, the connecting cavity, and the opening of the second ring body 120, thereby forming a second air duct 131 in the radial direction of the connector 100 (i.e., the radial direction of the first ring body 110 or the second ring body 120), so that external gas can enter the connecting cavity through the opening of the second ring body 120, enter the inner side of the first ring body 110 through the opening of the first ring body 110, and then flow to the motor assembly 300. It should be noted that the number of second air ducts 131 should correspond to the number of connecting portions 130.

[0140] A gap may be naturally formed between two adjacent connecting parts 130 . In a specific arrangement, the connecting parts 130 may be arranged at equal intervals to make the intervals between the two connecting parts 130 consistent, thereby improving the stability of the overall structure of the connector 100 .

[0141] The two adjacent connecting parts 130, and the part of the first ring body 110 and the part of the second ring body 120 located between the two connecting parts 130, can naturally form an air flow channel extending along the axial direction of the connecting member 100 (i.e., the axial direction of the first ring body 110 or the second ring body 120). The air flow channel is located on the outside of the connecting part 130 and is therefore not connected to the connecting cavity, so that the air flow channel serves as the third air duct 132.

[0142] During specific implementation, the area between the first ring body 110 and the second ring body 120 can be connected to the air outlet of the motor assembly 300, that is, the third air duct 132 is connected to the air outlet of the motor assembly 300, and the area inside the first ring body 110 can be connected to the air inlet of the motor assembly 300, that is, the first air duct 142 and the second air duct 131 are connected to the air inlet of the motor assembly 300, so as to prevent the airflows between the third air duct 132 and the second air duct 131 from interfering with each other, and ensure that the airflow can enter the interior of the first ring body 110 through the second air duct 131, and after passing through the motor assembly 300, be discharged from the third air duct 132 between the first ring body 110 and the second ring body 120.

[0143] Among them, reference Figures 8 to 12 As shown, a plurality of connecting portions 130 are evenly spaced in sequence along the circumference of the first ring body 110 .

[0144] This can increase the air volume of the second air duct 131 and the third air duct 132, so that the dust cup assembly 500 can more efficiently exhaust dust. In addition, providing multiple connecting parts 130 to connect the first ring body 110 and the second ring body 120 can also further improve the relative stability between the first ring body 110 and the second ring body 120.

[0145] And in some embodiments, reference Figures 8 to 12 As shown, the connecting member 100 further includes a supporting portion 140 . The supporting portion 140 is disposed in the first ring body 110 . The first ring body 110 is connected to the rotating assembly 200 via the supporting portion 140 .

[0146] The support portion 140 can provide stable support for the installation of the rotating assembly 200, and the support portion 140 can form a limiting support structure within the first ring body 110 to prevent the first ring body 110 and the second ring body 120 from deforming themselves.

[0147] Among them, reference Figures 8 to 12 As shown, a plurality of openings are sequentially spaced apart along the circumference of the support portion 140 , and the openings form a first air duct 142 .

[0148] By providing an opening on the support portion 140 to form the first air duct 142 , the structure of the first air duct 142 can be simplified, the structure of the connector 100 can be simplified, and the structure of the connector 100 can be made more compact.

[0149] Specifically, the openings are arranged around the center of the support portion 140, forming a radially extending grille structure on the support portion 140, thereby increasing the overall air intake of the first air duct 142. Furthermore, the first mounting portion 141 can be disposed at the center of the support portion 140 to facilitate connection between the support portion 140 and the rotating assembly 200.

[0150] Reference Figure 5As shown, an embodiment of the present application further provides a cleaning device, comprising a device body and the air duct structure of any of the above embodiments, wherein the air duct structure is arranged on the device body.

[0151] The air duct structure has been described in detail in the above embodiments and will not be repeated here.

[0152] In some embodiments, the device body includes: a shell 400, the shell 400 has a mounting cavity, and the shell 400 is respectively provided with a mounting port 410 and an exhaust port that are connected to the mounting cavity.

[0153] The motor assembly 300 is disposed in the installation cavity through the installation opening 410 and is communicated with the exhaust port.

[0154] The dust cup assembly 500 is connected to the mounting port 410 through an air duct structure.

[0155] It can be understood that a shell 400 is provided to accommodate the motor assembly 300, and the shell 400 is connected to the dust cup assembly 500 through the air duct structure provided in an embodiment of the present application, so that the motor assembly 300 can be connected to the dust cup assembly 500 through the air duct structure, making the overall structure of the cleaning device more compact.

[0156] The housing 400 is provided with an installation port 410 and an exhaust port that are connected to the installation cavity. The motor assembly 300 can be installed in the motor assembly 300 through the installation port 410. The air inlet of the motor assembly 300 is connected to the installation port 410, and the air outlet of the motor assembly 300 is connected to the exhaust port. Two exhaust ports can be formed on the housing 400 through a channel structure, namely a first exhaust port 420 and a second exhaust port 430. The first exhaust port 420 is located near the air outlet of the motor assembly 300 and is connected to the outside world. Figure 2 As shown, when the motor assembly 300 inhales gas from the dust cup assembly 500 through the first air duct 142, the gas is directly discharged to the outside through the first exhaust port 420; the second exhaust port 430 extends through the channel structure in the housing 400 to communicate with the third air duct 132 of the connector 100, as shown in FIG. Figure 5 As shown, when the motor assembly 300 inhales external air through the second air duct 131, the gas is guided to the second exhaust port 430 through the channel structure, and then discharged into the dust cup assembly 500 through the third air duct 132 of the connector 100.

[0157] It should be noted here that when the second exhaust port 430 exhausts air through the third air duct 132, it is necessary to use the sealing parts on the shell 400 or other external sealing structures (such as the sealing parts set on the base station 600, etc.) to close the first exhaust port 420 so that the gas can flow smoothly from the air outlet of the motor assembly 300 to the second exhaust port 430, and then be discharged through the third air duct 132.

[0158] An embodiment of the present application further provides a cleaning system, including a base station 600 and the above-mentioned cleaning device, where the cleaning device is connected to the base station 600.

[0159] The cleaning device and its air duct structure have been described in the above embodiments and will not be repeated here.

[0160] The air duct structure, cleaning device, and cleaning system provided by the embodiments of the present application are characterized by providing a connecting member 100 and a rotating assembly 200. The connecting member 100 has an air duct, and the air duct has a first air duct 142, a second air duct 131, and a third air duct 132. The rotating assembly 200 is rotatably connected to the connecting member 100, so that the rotating assembly 200 rotates relative to the connecting member 100 and switches between a first state and a second state. In the first state, the rotating assembly 200 closes the second air duct 131 and the third air duct 132 and opens the first air duct 142, so that the motor assembly 300 can suck dust into the dust cup through the first air duct 142. In the second state, the rotating assembly 200 closes the first air duct 142 and opens the second air duct 131 and the third air duct 132, so that the motor assembly 300 can suck external air through the second air duct 131 and blow the air into the dust cup assembly 500 through the third air duct 132 to discharge dust in the dust cup assembly 500.

[0161] Therefore, through the air duct structure provided in the embodiment of the present application, by rotating the rotating component 200, the motor component 300 can inhale or blow air relative to the dust cup component 500 without changing the motor component 300. When the dust cup component 500 is connected to the base station 600 (or other dust collecting devices, equipment, etc. with a dust collecting space), the dust can be discharged into the dust collecting part by itself under the blowing action of the motor component 300. There is no need to set up additional motor devices on the dust collecting parts such as the base station 600 to absorb dust, making the dust collection operation of the cleaning equipment and the cleaning system more convenient and quick, and simplifying the structure of the cleaning equipment and the cleaning system, reducing the cost of setting up the corresponding motor device.

[0162] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
