Description

Technical Field

[0001] This application relates to the field of cleaning appliance technology, and in particular to an air duct structure, cleaning equipment and cleaning system. Background Technology

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

[0003] In related technologies, the cleaning system includes a base station and cleaning equipment. The cleaning equipment includes a fan assembly, an air duct structure, and a dust cup assembly. The fan assembly is connected to the dust cup assembly via the air duct structure, which can switch the airflow direction. During cleaning, the fan assembly draws dust and dirt into the dust cup assembly through the air duct structure. Once the dust cup assembly is full, the air duct structure is at least partially rotated to change the airflow direction, allowing the fan assembly to blow air through the air duct structure and clean the dust cup assembly.

[0004] However, the existing air duct structure requires at least partial inversion to achieve wind direction switching, which occupies a large amount of space. Utility Model Content

[0005] This application provides an air duct structure, cleaning equipment, and cleaning system to solve the problem that existing air duct structures occupy a large amount of space when switching wind direction.

[0006] In a first aspect, embodiments of this application provide an air duct structure for cleaning equipment, the air duct structure comprising:

[0007] The connecting component is provided with a first air duct and a second air duct. The first air duct is used to connect with the outside world or the cleaning system, and the second air duct is used to connect with the dust cup assembly of the cleaning equipment. The connecting component is provided with an air inlet and an air outlet, both of which are connected to the first air duct and the second air duct. The air inlet is used to connect with the air inlet of the fan assembly of the cleaning equipment, and the air outlet is used to connect with the air outlet of the fan assembly.

[0008] A separator is rotatably mounted on the connecting assembly. The separator rotates relative to the connecting assembly to switch between a first state and a second state.

[0009] In the first state, the separator connects the first air duct and the air outlet, and connects the second air duct and the air inlet, so that the airflow enters the dust cup assembly and enters the air inlet section in sequence through the second air duct and the air inlet;

[0010] In the second state, the separator connects the first air duct and the air inlet, and connects the second air duct and the air outlet, so that the airflow from the outside or the cleaning system enters the air inlet section through the first air duct and the air inlet in sequence, and is discharged from the air outlet section through the air outlet and the second air duct into the dust cup assembly in sequence.

[0011] Thus, the air duct structure provided in this application embodiment includes a connecting component and a partition rotatably disposed on the connecting component. The connecting component has a first air duct, a second air duct, an air inlet, and an air outlet. Both the air inlet and the air outlet are connected to the first and second air ducts. The partition rotates relative to the connecting component and can switch between a first state and a second state. In the first state, the partition connects the first air duct and the air outlet, and connects the second air duct and the air inlet. Simultaneously, it disconnects the first air duct and the air inlet, and disconnects the second air duct and the air outlet, allowing airflow from the dust cup assembly into the air inlet of the fan assembly for normal dust collection. In the second state, the partition connects the first air duct and the air inlet, and connects the second air duct and the air outlet. Simultaneously, it disconnects the first air duct and the air outlet, and disconnects the second air duct and the air inlet, allowing airflow from the outside or the cleaning system to enter the air inlet of the fan assembly and exit from the air outlet of the fan assembly into the dust cup assembly to clean the dust cup assembly. The air duct structure can be switched by simply rotating the partition to connect different air ducts and vents. The position of the partition changes little, which reduces the space occupied by the movement of the partition and does not require changes to the position of the connecting components. This makes the air duct structure simpler and more compact, and the air duct switching is more convenient and faster, thus reducing the overall space occupied by the air duct structure for air direction switching.

[0012] In one possible implementation, the air duct structure provided in this application embodiment has a first air vent and a second air vent on the partition;

[0013] In the first state, the second air vent connects to the first air duct and the air outlet, and the first air vent connects to the second air duct and the air inlet.

[0014] In the second state, the first air vent connects to the first air duct and the air inlet, and the second air vent connects to the second air duct and the air outlet.

[0015] In this way, the first air duct, the second air duct, the air inlet and the air outlet can be connected smoothly through the first air vent and the second air vent, and the first air duct, the second air duct, the air inlet and the air outlet can be disconnected through the parts other than the first air vent and the second air vent on the separator, thereby meeting the requirements for air direction switching.

[0016] In one possible implementation, the air duct structure provided in this application embodiment has at least two first air outlets, and the at least two first air outlets are spaced apart around the rotation axis of the separator.

[0017] At least two second air vents are provided, and the at least two second air vents are alternately arranged relative to the first air vents around the rotation axis of the separator, and are located on the outer periphery of each first air vent.

[0018] This allows for a more rational layout of the first and second air vents, and facilitates their correspondence with the first and second air ducts, air inlets, and air outlets on the connecting components, resulting in a more uniform airflow distribution and easier switching of airflow direction.

[0019] In one possible implementation, the air duct structure provided in this application embodiment includes a partition comprising:

[0020] The partition body, the first air vent and the second air vent are both set on the partition body, and the partition body and the connecting components are rotatably connected by the mounting parts;

[0021] An operating unit is located on one side of the partition body and is configured to drive the partition body to rotate relative to the connecting assembly under the action of an external force.

[0022] This makes it easier to rotate the partition body and its first and second air vents by applying external force to the operating part, making the airflow direction switching operation of the air duct structure more convenient.

[0023] In one possible implementation, the air duct structure provided in this application includes the following connecting components:

[0024] The fan mounting bracket is used to connect to the fan assembly. Both the air inlet and the air outlet are located on the fan mounting bracket.

[0025] The connecting seat is connected to the fan mounting bracket and is used to connect to the dust cup assembly. Both the first air duct and the second air duct are set on the connecting seat.

[0026] The separator is disposed between the fan mounting bracket and the connecting seat, and is rotatably connected to at least one of the fan mounting bracket and the connecting seat.

[0027] This makes the overall structure of the air duct simpler and more compact, with a high degree of modularity, making it easier to assemble and replace the components. At the same time, the air inlet and outlet are set on the fan mounting bracket, and the first and second air ducts are set on the connecting seat, making the layout of the air duct structure more reasonable and improving the airflow transmission efficiency.

[0028] In one possible implementation, the air duct structure provided in this application embodiment includes a fan mounting bracket comprising:

[0029] The first fixing ring, the inner ring of the first fixing ring forms an air inlet;

[0030] The second fixing ring is sleeved on the outside of the first fixing ring;

[0031] At least one support rib connects the first fixing ring and the second fixing ring, and the support rib divides the space between the first fixing ring and the second fixing ring to form at least one air outlet;

[0032] At least one of the first fixing ring, the second fixing ring, and the support rib is connected to the wind turbine assembly.

[0033] In this way, the first fixed ring and the second fixed ring are connected by at least one supporting rib to ensure the structural strength of the fan mounting frame. The inner ring of the first fixed ring forms an air inlet, while the space between the first fixed ring and the second fixed ring is separated by the supporting rib to form at least one air outlet, so as to achieve relative independence between the air inlet and the air outlet and reduce mutual interference between the air inlet and the air outlet.

[0034] In one possible implementation, the air duct structure provided in this application embodiment includes a connecting seat comprising:

[0035] The mounting platform is used to connect to the fan assembly, and the second air duct is set on the mounting platform and passes through the mounting platform;

[0036] The annular platform is mounted on the mounting platform, and the first air duct is mounted on the annular platform.

[0037] In this way, the second air duct is set on the mounting platform and runs through the mounting platform, while the first air duct is set on the ring platform, making full use of the space of each part of the connecting seat, so that the air ducts are arranged in an orderly and efficient manner, and avoiding interference between the two air ducts.

[0038] In one possible implementation, the air duct structure provided in this application embodiment includes a mounting part and a plurality of partition ribs disposed on the mounting platform. The mounting part is located at the center of the annular platform, and one side of the partition ribs is connected to the annular platform, while the other side is connected to the mounting part.

[0039] The space between two adjacent partition ribs extends through the mounting platform to form a second air duct;

[0040] The annular platform has a cavity for communicating with the outside world or cleaning equipment. The space between two adjacent partition ribs in another part communicates with the cavity to form a first air duct together with the cavity. The first air duct and the second air duct are alternately distributed around the mounting part.

[0041] Thus, the installation section and the partition ribs ensure the installation strength of the connector and facilitate the connection between the connector and the partition. The first and second air ducts are alternately distributed around the installation section and separated from each other by the partition ribs, so that the two air ducts are relatively independent and orderly arranged, which can effectively reduce the interference between airflows and make the air intake and exhaust smoother.

[0042] Secondly, embodiments of this application provide a cleaning device, including a device body and any of the aforementioned air duct structures, wherein the air duct structure is connected to the device body.

[0043] Thirdly, embodiments of this application provide a cleaning system, including a base station and the aforementioned cleaning equipment, wherein the cleaning equipment is connected to the base station.

[0060] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0061] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the absence of conflict, the following embodiments and features can be combined with each other.

[0062] In related technologies, the cleaning system includes a base station and cleaning equipment. The cleaning equipment includes a fan assembly, an air duct structure, and a dust cup assembly. The fan assembly is connected to the dust cup assembly via the air duct structure, which can switch the airflow direction. During cleaning, the fan assembly draws dust and dirt into the dust cup assembly through the air duct structure. Once the dust cup assembly is full, the air duct structure is at least partially rotated to change the airflow direction, allowing the fan assembly to blow air through the air duct structure and clean the dust cup assembly.

[0063] In this case, the duct structure needs to be flipped to switch the air direction. This requires the flipping component to move closer to or further away from the fan around its own rotation axis, and to change the relative position of itself and the fan so that its different positions can be connected with the air inlet or outlet of the fan to achieve the air direction switch. For this purpose, additional flipping space needs to be reserved in the duct structure.

[0064] However, the above setup will result in the air duct structure occupying a large amount of space.

[0065] To overcome the deficiencies in the prior art, this application provides an air duct structure, cleaning equipment, and cleaning system. The air duct structure includes a connecting assembly and a partition rotatably mounted on the connecting assembly. The connecting assembly has a first air duct, a second air duct, an air inlet, and an air outlet. Both the air inlet and the air outlet are connected to the first and second air ducts. The partition rotates relative to the connecting assembly and can switch between a first state and a second state. In the first state, the partition connects the first air duct and the air outlet, and the second air duct and the air inlet, while simultaneously disconnecting the first air duct and the air inlet, and disconnecting the second air duct and the air outlet, allowing airflow from the dust cup assembly into the air inlet of the fan assembly for normal dust collection. In the second state, the partition connects the first air duct and the air inlet, and the second air duct and the air outlet, while simultaneously disconnecting the first air duct and the air outlet, and disconnecting the second air duct and the air inlet, allowing airflow from the outside or the cleaning system to enter the air inlet of the fan assembly and exit from the air outlet of the fan assembly into the dust cup assembly to clean the dust cup assembly. The air duct structure can be switched by simply rotating the partition to connect different air ducts and vents. The position of the partition changes little, which reduces the space occupied by the movement of the partition and does not require changes to the position of the connecting components. This makes the air duct structure simpler and more compact, and the air duct switching is more convenient and faster, thus reducing the overall space occupied by the air duct structure for air direction switching.

[0066] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.

[0067] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, this application embodiment provides an air duct structure 300 for cleaning equipment. The air duct structure 300 includes:

[0068] The connecting component 310 is provided with a first air duct 301 and a second air duct 302. The first air duct 301 is used to communicate with the outside world or the cleaning system, and the second air duct 302 is used to communicate with the dust cup assembly of the cleaning equipment. The connecting component 310 is provided with an air inlet 303 and an air outlet 304. Both the air inlet 303 and the air outlet 304 are connected to the first air duct 301 and the second air duct 302. The air inlet 303 is used to communicate with the air inlet 1111 of the fan assembly 110 of the cleaning equipment, and the air outlet 304 is used to communicate with the air outlet 1112 of the fan assembly 110.

[0069] The separator 320 and the separator 330 are rotatably disposed on the connecting assembly 310. The separator 320 rotates relative to the connecting assembly 310 to switch between a first state and a second state.

[0070] In the first state, the separator 320 connects the first air duct 301 and the air outlet 304, and connects the second air duct 302 and the air inlet 303, so that the airflow enters the dust cup assembly and enters the air inlet 1111 in sequence through the second air duct 302 and the air inlet 303.

[0071] In the second state, the separator 320 connects the first air duct 301 and the air inlet 303, and connects the second air duct 302 and the air outlet 304, so that the airflow from the outside or the cleaning system enters the air inlet 1111 in sequence through the first air duct 301 and the air inlet 303, and is discharged from the air outlet 1112 into the dust cup assembly in sequence through the air outlet 304 and the second air duct 302.

[0072] The connecting component 310 can be connected to the fan assembly 110 on one side and to the dust cup assembly on the other side, thus forming a complete airflow channel. The fan 111 of the fan assembly 110 is covered with a sealing cover 112, and the air inlet 1111 of the fan 111 and the opening of the sealing cover 112 face the same side. The air outlet 1112 of the fan 111 is connected to the sealing cover 112, so that the airflow drawn in by the air inlet 1111 of the fan 111 is discharged from the air outlet 1112 and discharged along the opening of the sealing cover 112. That is, the air inlet and air outlet of the fan assembly 110 are both located on the same side, and the air outlet is arranged around the periphery of the air inlet.

[0073] The connecting assembly 310 is provided with a first air duct 301 and a second air duct 302. The first air duct 301 is connected to the outside environment or the cleaning system, so that airflow from the outside environment or the cleaning system can enter the connecting assembly 310 through the first air duct 301, or allow airflow to be discharged from the connecting assembly 310 to the outside environment. The second air duct 302 is used to connect to the dust cup assembly of the cleaning equipment, thereby drawing or blowing airflow into the dust cup assembly. The connecting assembly 310 is also provided with an air inlet 303 and an air outlet 304. The air inlet 303 is connected to both the first air duct 301 and the second air duct 302, and the air outlet 304 is also connected to both the first air duct 301 and the second air duct 302. Furthermore, the air inlet 303 is connected to the air inlet section 1111 of the fan assembly 110, and the air outlet 304 is connected to the air outlet section 1112 of the fan assembly 110.

[0074] A separator 320 is rotatably mounted on the connecting assembly 310 via a mounting member 330. The mounting member 330 can be a bolt, screw, shaft, pin, or other workpiece that can rotatably engage with the separator 320. The separator 320 rotates relative to the connecting assembly 310 and can switch between a first state and a second state.

[0075] In the first state, the separator 320 connects the first air duct 301 and the air outlet 304, and connects the second air duct 302 and the air inlet 303. Simultaneously, the first air duct 301 and the air inlet 303 are disconnected, and the second air duct 302 and the air outlet 304 are disconnected, allowing airflow from the dust cup assembly into the air inlet 1111 of the fan assembly 110 for normal dust collection. In the second state, the separator 320 connects the first air duct 301 and the air inlet 303, and connects the second air duct 302 and the air outlet 304. Simultaneously, the first air duct 301 and the air outlet 304 are disconnected, and the second air duct 302 and the air inlet 303 are disconnected, allowing airflow from the outside or the cleaning system to enter the air inlet 1111 of the fan assembly 110 and exit from the air outlet 1112 of the fan assembly 110 into the dust cup assembly to clean it.

[0076] Thus, the air duct structure 300 provided in this embodiment includes a connecting component 310 and a partition 320 rotatably mounted on the connecting component 310. The connecting component 310 has a first air duct 301, a second air duct 302, an air inlet 303, and an air outlet 304. Both the air inlet 303 and the air outlet 304 are connected to the first air duct 301 and the second air duct 302. The partition 320 rotates relative to the connecting component 310 and can switch between a first state and a second state to achieve dust suction or dust cup cleaning of the cleaning equipment. The air duct switching of the air duct structure 300 only requires rotating the partition 320 to connect different air ducts and air outlets. The position change of the partition 320 is small, which reduces the space occupied by the movement of the partition 320, and there is no need to change the position of the connecting component 310. Therefore, the air duct structure 300 is simpler and more compact, and the air duct switching is more convenient and faster, resulting in a reduction in the overall space occupied by the air duct structure 300 for air direction switching.

[0077] In some embodiments, refer to Figure 2 and Figure 3 As shown, the partition 320 has a first air vent 3211 and a second air vent 3212.

[0078] In the first state, the second air outlet 3212 is connected to the first air duct 301 and the air outlet 304, and the first air outlet 3211 is connected to the second air duct 302 and the air inlet 303.

[0079] In the second state, the first air vent 3211 is connected to the first air duct 301 and the air inlet 303, and the second air vent 3212 is connected to the second air duct 302 and the air outlet 304.

[0080] It is understandable that the separator 320 can flexibly switch the airflow path between the air inlet 303, the air duct, and the air outlet 304 through the connection and combination of different air vents. Furthermore, it can smoothly achieve the connection and switching between the first air duct 301, the second air duct 302, the air inlet 303, and the air outlet 304 through the first air vent 3211 and the second air vent 3212, and disconnect the first air duct 301, the second air duct 302, the air inlet 303, and the air outlet 304 through parts other than the first air vent 3211 and the second air vent 3212 on the separator 320, thereby meeting the requirements for airflow direction switching.

[0081] Specifically, the air inlet 303 is always connected to the air inlet 1111 of the fan assembly 110, and the air outlet 304 is always connected to the air outlet 1112 of the fan assembly 110. In this way, when the separator 320 rotates, the first air outlet 3211 is always connected to the air inlet 303, and the second air outlet 3212 is always connected to the air outlet 304. Thus, by controlling the opening and closing of the first air duct 301 and the second air duct 302 through the separator 320, the air direction of the air duct assembly can be switched, making the air direction switching and structural coordination of the connecting assembly 310 and the separator 320 simpler.

[0082] In some embodiments, refer to Figure 3 As shown, at least two first air vents 3211 are provided, and at least two first air vents 3211 are spaced apart around the rotation axis of the separator 320;

[0083] At least two second air vents 3212 are provided, and the at least two second air vents 3212 are alternately arranged relative to the first air vent 3211 around the rotation axis of the separator 320, and are located on the outer periphery of each first air vent 3211.

[0084] It is understandable that the first air vent 3211 is fan-shaped and the second air vent 3212 is arc-shaped, and the area of ​​the first air vent 3211 can be greater than or equal to the area of ​​the second air vent 3212. Setting at least two first air vents 3211 and at least two second air vents 3212 can make the airflow in and out of the fan assembly 110 more uniform, avoid the airflow from concentrating in one place, reduce the situation of excessive or insufficient local pressure, make the air pressure in the entire cleaning equipment more balanced, and thus improve the stability and efficiency of the cleaning equipment operation.

[0085] The rotation axis of the separator 320 is the central axis of the mounting component 330. The first air outlet 3211 and the second air outlet 3212 are alternately arranged around the rotation axis of the separator 320, so that the first air outlet 3211 and the second air outlet 3212 are staggered, providing a more flexible airflow control method. At the same time, since the air outlet 1112 of the fan assembly 110 is located on the outer periphery of the air inlet 1111, and the second air outlet 3212 is located on the outer periphery of the first air outlet 3211, it is easier for the first air outlet 3211 to connect with the air inlet 1111 of the fan assembly 110 through the air inlet 303, and for the second air outlet 3212 to connect with the air outlet 1112 of the fan assembly 110 through the air outlet 304.

[0086] This makes the layout of the first air vent 3211 and the second air vent 3212 more reasonable, and facilitates the correspondence between the first air vent 3211 and the second air vent 3212 and the first air duct 301, the second air duct 302, the air inlet 303 and the air outlet 304 on the connecting component 310, so that the airflow distribution is more uniform and the airflow direction switching is easier.

[0087] In specific implementation, refer to Figure 3 As shown, the separator 320 includes:

[0088] The partition body 321, the first air vent 3211 and the second air vent 3212 are both set on the partition body 321, and the partition body 321 and the connecting assembly 310 are rotatably connected by the mounting part 330.

[0089] An operating unit 322 is provided on one side of the partition body 321. The operating unit 322 is configured to drive the partition body 321 to rotate relative to the connecting assembly 310 under the action of an external force.

[0090] The dividing body 321 can be a circular piece to reduce the space occupied by the dividing member 320. The area of ​​the circular piece is greater than or equal to the cross-sectional area of ​​the connecting component 310 at the installation location of the dividing member 320, so that the dividing body 321 can stably divide the first air duct 301, the second air duct 302, and the air inlet 303 and the air outlet 304. The dividing body 321 has a hole, and the mounting member 330 passes through the hole and is connected to the connecting component 310, thereby realizing the rotatable connection of the dividing body 321 through the mounting member 330.

[0091] The operating part 322 is located on one side of the partition body 321, which reduces space occupation and makes it easy to apply external force to the operating part 322 to drive the partition body 321 to rotate, making the operation more convenient and safe. This makes it easier to rotate the partition body 321 and its first air vent 3211 and second air vent 3212 by applying external force to the operating part 322, making the air direction switching operation of the air duct structure 300 more convenient.

[0092] Furthermore, in some embodiments, reference is made to Figure 1 and Figure 2 As shown, the connection component 310 includes:

[0093] The fan mounting bracket 311 is used to connect to the fan assembly 110. The air inlet 303 and the air outlet 304 are both provided on the fan mounting bracket 311.

[0094] The connecting seat 312 is connected to the fan mounting bracket 311 and is used to connect to the dust cup assembly. The first air duct 301 and the second air duct 302 are both set on the connecting seat 312.

[0095] The separator 320 is disposed between the fan mounting bracket 311 and the connecting seat 312, and is rotatably connected to at least one of the fan mounting bracket 311 and the connecting seat 312.

[0096] The fan mounting bracket 311 connects to the fan assembly 110. The air inlet 303 and the air outlet 304 are both set on the fan mounting bracket 311. The connecting seat 312 connects to the dust cup assembly. The first air duct 301 and the second air duct 302 are both set on the connecting seat 312, realizing the modular setting of the connecting assembly 310, which is convenient for disassembly and assembly, and easy to integrate in an orderly manner, reducing the overall space occupied by the air duct structure 300.

[0097] The separator 320 is disposed between the fan mounting bracket 311 and the connecting seat 312, and can be rotatably connected to at least one of them, ensuring a stable connection between the connecting seat 312, the separator 320, and the fan mounting bracket 311. This makes the overall structure of the duct structure 300 simpler and more compact, with a high degree of modularity, facilitating the assembly and replacement of components. It also makes the layout of the duct structure 300 more rational, improving airflow transmission efficiency.

[0098] Among them, reference Figure 2 and Figure 4 As shown, the fan mounting bracket 311 includes:

[0099] The first fixing ring 3111, the inner ring of the first fixing ring 3111 forms the air inlet 303;

[0100] The second fixing ring 3112 is sleeved on the outside of the first fixing ring 3111;

[0101] At least one support rib 3113, the support rib 3113 connects the first fixing ring 3111 and the second fixing ring 3112, and the support rib 3113 divides the space between the first fixing ring 3111 and the second fixing ring 3112 to form at least one air outlet 304.

[0102] At least one of the first fixing ring 3111, the second fixing ring 3112, and the support rib 3113 is connected to the fan assembly 110.

[0103] The first fixing ring 3111 can be configured to correspond to the size of the air inlet 1111 of the fan 111 of the fan assembly 110, and the second fixing ring 3112 can be configured to correspond to the size of the sealing cover 112 of the fan assembly 110, so that the second fixing ring 3112 can be connected to the air outlet 1112.

[0104] The inner ring of the first fixed ring 3111 forms an air inlet 303, while the space between the first fixed ring 3111 and the second fixed ring 3112 is separated by the support rib 3113 to form at least one air outlet 304, making the air inlet 303 and the air outlet 304 relatively independent, thereby reducing the mutual interference between the air inlet and the air outlet, making the airflow smoother, thus improving the working efficiency of the fan 111 and reducing energy loss.

[0105] Furthermore, the multiple support ribs 3113 divide and form multiple air outlets 304, which can make the exhaust airflow more evenly distributed around the air inlet 303 and avoid airflow concentration.

[0106] Furthermore, referring to Figure 2 , Figure 5 and Figure 6 As shown, the connector 312 includes:

[0107] Mounting platform 3121 is used to connect to fan assembly 110. Second air duct 302 is set on mounting platform 3121 and passes through mounting platform 3121.

[0108] The annular platform 3122 is mounted on the mounting platform 3121, and the first air duct 301 is mounted on the annular platform 3122.

[0109] The second air duct 302 is set on the mounting platform 3121 and runs through the mounting platform 3121, while the first air duct 301 is set on the annular platform 3122. This makes the spatial layout of each part of the connecting seat 312 more reasonable, avoids the chaos of air duct setting and the waste of space, and makes the air duct arrangement more orderly and efficient.

[0110] Furthermore, the first air duct 301 and the second air duct 302 are respectively set on the annular platform 3122 and the mounting platform 3121, realizing the relative independence of different air ducts, thereby reducing airflow interference between different air ducts and improving airflow transmission efficiency.

[0111] Specifically, refer to Figure 2 , Figure 5 and Figure 6As shown, the connecting seat 312 also includes a mounting part 3123 and a plurality of partition ribs 3124 disposed on the mounting platform 3121. The mounting part 3123 is located at the center of the annular platform 3122, and one side of the partition rib 3124 is connected to the annular platform 3122 and the other side is connected to the mounting part 3123.

[0112] The space between two adjacent partition ribs 3124 extends through the mounting platform 3121 to form a second air duct 302;

[0113] The annular platform 3122 has a cavity for communicating with the outside world or cleaning equipment. The space between two adjacent partition ribs 3124 in another part communicates with the cavity to form a first air duct 301 together with the cavity. The first air duct 301 and the second air duct 302 are alternately distributed around the mounting part 3123.

[0114] The mounting part 3123 is connected to the mounting member 330 to achieve coaxial rotational connection of the separator 320 relative to the annular platform 3122.

[0115] The annular platform 3122 has a cavity inside. An air guide 3125 communicating with the cavity is provided on the outer ring wall of the annular platform 3122, and it is connected to the outside world or a cleaning system through the air guide 3125. An opening is made on the inner ring wall of the annular platform 3122 so that the space between two adjacent partition ribs 3124 is connected to the cavity.

[0116] The mounting portion 3123 and the partition rib 3124 ensure the installation strength of the connecting seat 312 and facilitate the connection between the connecting seat 312 and the partition 320. The first air duct 301 and the second air duct 302 are alternately distributed around the mounting portion 3123 and separated from each other by the partition rib 3124, so that the two air ducts are relatively independent and orderly arranged, which can effectively reduce the interference between airflows and make the air intake and exhaust smoother.

[0117] This application embodiment also provides a cleaning device, including a device body and any of the above-mentioned air duct structures 300, wherein the air duct structure 300 is connected to the device body.

[0118] The air duct structure 300 has been described in detail in the above embodiments and will not be repeated here.

[0119] This application also provides a cleaning system, including a base station and the aforementioned cleaning equipment, wherein the cleaning equipment is connected to the base station.

[0120] The cleaning equipment and system provided in this application embodiment, by setting an air duct structure 300, includes a connecting component 310 and a separator 320 rotatably mounted on the connecting component 310. The connecting component 310 has a first air duct 301, a second air duct 302, an air inlet 303, and an air outlet 304. The air inlet 303 and the air outlet 304 are both connected to the first air duct 301 and the second air duct 302. The separator 320 rotates relative to the connecting component 310 and can switch between a first state and a second state. In the first state, the separator 320 connects the first air duct 301 and the air outlet 304, and connects the second air duct 302 and the air inlet 303. At the same time, it disconnects the first air duct 301 and the air inlet 303, and disconnects the second air duct 302 and the air outlet 304, so that airflow enters the air inlet 1111 of the fan assembly 110 from the dust cup assembly, thereby achieving normal dust collection. In the second state, the separator 320 connects the first air duct 301 and the air inlet 303, and the second air duct 302 and the air outlet 304. Simultaneously, the first air duct 301 and the air outlet 304 are disconnected, and the second air duct 302 and the air inlet 303 are disconnected, allowing airflow from the outside or the cleaning system to enter the air inlet 1111 of the fan assembly 110 and exit from the air outlet 1112 of the fan assembly 110 into the dust cup assembly to clean it. Switching the air duct structure 300 only requires rotating the separator 320 to connect different air ducts and outlets. The positional change of the separator 320 is minimal, reducing the space occupied by its movement. Furthermore, there is no need to change the position of the connecting assembly 310, making the air duct structure 300 simpler and more compact, and making air duct switching more convenient and faster. This reduces the overall space occupied by the air duct structure 300 for changing air direction.
