Description

Technical Field

[0001] This application relates to the field of clean electrical technology, and more particularly to a cleaning device and a cleaning system. Background Technology

[0002] As living standards improve, people have higher requirements for the quality of their living environment, and household dust removal devices such as vacuum cleaners and floor scrubbers are increasingly appearing in people's lives.

[0003] In related technologies, a cleaning system may include a base station and a cleaning device. The cleaning device is detachably connected to the base station. The cleaning device includes a device body and a dust cup mounted on the device body. The device body contains a fan assembly, and the dust cup has an openable end cap. When the device body is in operation, the fan assembly sucks debris from the surface to be cleaned into the dust cup. When the base station docks with the device body, it opens the end cap, and then uses the fan assembly within the device body to generate suction to provide negative pressure to the base station, thereby recovering the debris from the dust cup.

[0004] However, the airflow generated by the fan components is eventually discharged into the external environment, and the airflow is not fully utilized, resulting in debris remaining in the dust cup. Utility Model Content

[0005] This application provides a cleaning device and a cleaning system to solve the problem that the airflow generated by the operation of the fan assembly is eventually discharged into the external environment, the airflow is not fully utilized, and debris remains in the dust cup.

[0006] Firstly, the cleaning equipment provided in this application includes:

[0007] The main body of the equipment is equipped with a fan assembly.

[0008] Dust cup assembly, which is mounted on the main body of the device;

[0009] The air duct structure is set on the main body of the equipment. The air duct structure connects the dust cup assembly and the fan assembly. The air duct structure moves relative to the dust cup assembly to switch between a first state and a second state.

[0010] In the first state, the duct structure guides the airflow through the dust cup assembly into the fan assembly, so that the dust cup assembly collects the debris on the surface to be cleaned; in the second state, the dust cup assembly and the duct structure are respectively connected to the base station, and the duct structure guides the airflow from the fan assembly to the dust cup assembly, so that the base station collects the debris inside the dust cup assembly.

[0011] Thus, in the second state, the airflow generated by the fan assembly can be fully utilized to form an airflow circulation between the dust cup assembly, the base station, the fan assembly, and the duct structure, thereby saving energy consumption of the fan assembly. Furthermore, the duct structure can guide the airflow from the fan assembly to the dust cup assembly, further cleaning debris inside the dust cup assembly and preventing incomplete dust collection at the base station, which could result in debris residue inside the dust cup assembly.

[0012] In one possible implementation, the cleaning device provided in this application includes a dust cup assembly comprising a dust cup body and a filter element. The dust cup body is disposed on the main body of the device and is connected to the air duct structure to form a dust collection chamber. The filter element is disposed inside the dust collection chamber.

[0013] When the duct structure is in the first state, the filter element is used to filter the airflow entering the fan assembly; when the duct structure is in the second state, the airflow is blown from the fan assembly to the filter element to clean the debris on the filter element.

[0014] Thus, when the duct structure is in its first state, the filter can prevent debris from entering the fan assembly, thus avoiding damage to the fan assembly. When the duct structure is in its second state, it can guide airflow from the fan assembly to the filter to clean the debris attached to the filter, thereby improving the cleaning efficiency of the cleaning equipment in subsequent vacuuming operations.

[0015] In one possible implementation, the cleaning device provided in this application has a dust cup cover on the dust cup body;

[0016] When the dust cup body is connected to the base station, the dust cup cover moves relative to the dust cup body to open the dust collection chamber.

[0017] Thus, when the dust cup body is connected to the base station, the dust collection chamber is opened through the dust cup cover to connect the dust collection chamber with the dust collection bin of the base station, thereby collecting the debris in the dust collection chamber.

[0018] In one possible implementation, the cleaning equipment provided in this application includes a fan assembly comprising a fan and a sealing cover. The sealing cover is disposed on the main body of the equipment, the fan is disposed inside the sealing cover, the sealing cover is connected to the air duct structure, and the outer wall of the fan assembly, the inner wall of the sealing cover, and the air duct structure together form an air outlet channel, which is connected to the air outlet of the fan.

[0019] In the first state, the air outlet guides the airflow through the duct structure to be discharged into the external environment; in the second state, the air outlet guides the airflow through the duct structure to be blown toward the dust cup assembly.

[0020] In this way, the air outlet channel is formed by the fan assembly, sealing cover and air duct structure to optimize the airflow path and ensure that both the air outlet and air inlet of the fan are connected to the air duct structure.

[0021] In one possible implementation, the cleaning equipment provided in this application further includes a seal, which is disposed inside a sealing cover and between the air inlet of the fan and the air duct structure, and the air outlet duct is disposed around the periphery of the air inlet of the fan.

[0022] Thus, the air outlet duct is arranged around the periphery of the fan's air inlet, facilitating communication between the air inlet and outlet ducts and the ductwork structure, resulting in a more compact overall structure. Furthermore, a seal is used to fill the gap between the air inlet and the ductwork structure to prevent gas leakage.

[0023] In one possible implementation, the cleaning equipment provided in this application has a connection channel on its air duct structure, which is used to connect to a base station;

[0024] In the first state, the connecting channel is connected to the air outlet channel so that the airflow is discharged to the outside environment through the air outlet channel and the connecting channel in sequence; in the second state, the connecting channel connects the air inlet of the fan to the base station so that the airflow returns from the base station to the fan.

[0025] Thus, when the cleaning equipment is in vacuum mode, the connecting channel connects the air outlet channel to the external environment, and the airflow flows out from the fan's outlet and is discharged into the external environment through the air outlet channel and the connecting channel in sequence. When the cleaning equipment is in dust collection mode, the airflow flows from the dust collection chamber of the base station to the connecting channel, and then to the fan's inlet.

[0026] In one possible implementation, the cleaning equipment provided in this application has a first air duct and a second air duct in its air duct structure;

[0027] In the first state, the first air duct connects the air outlet duct and the connecting duct, and the second air duct connects the dust collection chamber and the air inlet of the fan; in the second state, the first air duct connects the connecting duct and the air inlet of the fan, and the second air duct connects the air outlet duct and the dust collection chamber.

[0028] Thus, when the cleaning equipment is in the dust suction state, the airflow flows sequentially through the dust collection chamber, the second air duct, the air inlet of the fan, the air outlet of the fan, the air outlet channel, and the first air duct, and is finally discharged to the external environment through the connecting channel; when the cleaning equipment is in the dust collection state, the gas flows sequentially along the dust collection chamber, the dust collection bin of the base station, the connecting channel, the first air duct, the air inlet of the fan, the air outlet of the fan, the air outlet channel, and the second air duct, and then re-enters the dust collection chamber, thereby forming an airflow circulation.

[0029] In one possible implementation, the cleaning device provided in this application includes an air duct structure comprising:

[0030] The connecting component, the first air duct and the second air duct are both set on the connecting component. The connecting component connects the dust cup body and the fan, and together with the dust cup body, they form a dust collection chamber.

[0031] A separator is rotatably mounted on the connecting assembly and rotates relative to the connecting assembly to switch between a first state and a second state.

[0032] In this way, switching between air ducts only requires rotating the partition to connect different air ducts and vents. The position of the partition changes little and there is no need to change the position of the connecting components, making the air duct structure simple and compact, and the air duct switching more convenient and quick.

[0033] In one possible implementation, the cleaning equipment provided in this application has a first air vent and a second air vent on the partition.

[0034] In the first state, the first air outlet connects the second air duct to the air inlet of the fan assembly, and the second air outlet connects the first air duct to the air outlet; in the second state, the first air outlet connects the first air duct to the air inlet of the fan assembly, and the second air outlet connects the second air duct to the air outlet.

[0035] 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.

[0036] Secondly, the cleaning system provided in this application includes a base station and any of the cleaning devices mentioned above;

[0037] The base station has a connected dust collection chamber and a third air duct. The dust collection chamber is used to connect with the dust cup assembly of the cleaning equipment, and the third air duct is used to connect with the air duct structure of the cleaning equipment.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0065] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0066] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0067] In related technologies, a cleaning system may include a base station and a cleaning device. The cleaning device is detachably connected to the base station. The cleaning device includes a device body and a dust cup mounted on the device body. The device body contains a fan assembly, and the dust cup has an openable end cap. When the device body is in operation, the fan assembly sucks debris from the surface to be cleaned into the dust cup. When the base station docks with the device body, it opens the end cap and then uses the fan assembly within the device body to generate suction to provide negative pressure to the base station, thereby recovering the debris from the dust cup.

[0068] However, the airflow generated by the fan components is eventually discharged into the external environment, and the airflow is not fully utilized, resulting in debris remaining in the dust cup.

[0069] In view of the above problems, this application provides a cleaning device and a cleaning system. The cleaning device includes a device body, a dust cup assembly, and an air duct structure. A fan assembly is disposed on the device body, the dust cup assembly is disposed on the device body, and the air duct structure is disposed on the device body, connecting the dust cup assembly and the fan assembly. The air duct structure moves relative to the dust cup assembly to switch between a first state and a second state. In the first state, the air duct structure guides airflow through the dust cup assembly into the fan assembly, so that the dust cup assembly collects debris from the surface to be cleaned. In the second state, the dust cup assembly and the air duct structure are respectively connected to a base station, and the air duct structure guides airflow from the fan assembly to the dust cup assembly, so that the base station collects debris from inside the dust cup assembly. Thus, in the second state, the airflow generated by the fan assembly can be fully utilized to form an airflow circulation between the dust cup assembly, the base station, the fan assembly, and the air duct structure, thereby saving energy consumption of the fan assembly. Furthermore, the air duct structure can guide airflow from the fan assembly to the dust cup assembly, thus further cleaning the debris inside the dust cup assembly and preventing incomplete dust collection in the base station, which could result in debris residue inside the dust cup assembly.

[0070] The specific implementation methods of the cleaning equipment and cleaning system provided in this application will be described in detail below with reference to the accompanying drawings.

[0071] Reference Figures 1 to 15 As shown, the cleaning device 10 provided in this embodiment includes a device body 100, a dust cup assembly 200, and an air duct structure 300. A fan assembly 110 is disposed on the device body 100, the dust cup assembly 200 is disposed on the device body 100, and the air duct structure 300 is disposed on the device body 100. The air duct structure 300 connects the dust cup assembly 200 and the fan assembly 110. The air duct structure 300 moves relative to the dust cup assembly 200 to switch between a first state and a second state.

[0072] It is understood that the cleaning device 10 provided in this application embodiment can be a vacuum cleaner. The cleaning device 10 has a vacuuming state and a dust collection state. In the vacuuming state, the fan assembly 110 generates suction to provide negative pressure to the dust cup assembly 200, thereby drawing debris from the surface to be cleaned into the dust cup assembly 200. In the dust collection state, the cleaning device 10 is connected to the base station 20, and the fan assembly 110 generates suction to provide negative pressure to the base station 20, thereby collecting debris from the dust cup assembly 200 into the dust collection chamber 201 of the base station 20.

[0073] Reference Figure 2 and Figure 4As shown, in the first state, the air duct structure 300 guides the airflow through the dust cup assembly 200 into the fan assembly 110, so that the dust cup assembly 200 collects debris from the surface to be cleaned. The first state of the air duct structure 300 corresponds to the suction state of the cleaning device 10. Thus, under the action of the fan assembly 110, airflow from the external environment enters the dust cup assembly 200, passes through the air duct structure 300, and then enters the fan assembly 110. The fan assembly 110 then discharges the airflow back into the external environment, thereby achieving the purpose of the dust cup assembly 200 sucking up debris from the surface to be cleaned.

[0074] Reference Figure 1 , Figures 5 to 7 As shown, in the second state, the dust cup assembly 200 and the air duct structure 300 are respectively connected to the base station 20. The air duct structure 300 guides the airflow from the fan assembly 110 to the dust cup assembly 200, so that the base station 20 collects the debris inside the dust cup assembly 200. The second state of the air duct structure 300 corresponds to the dust collection state of the cleaning device 10. In this way, the fan assembly 110 generates suction to provide negative pressure to the base station 20, collecting the debris inside the dust cup assembly 200 into the dust collection chamber 201 of the base station 20. The airflow then enters the base station 20 from the dust cup assembly 200 and flows back to the fan assembly 110. The air duct structure 300 then guides the airflow from the fan assembly 110 to the dust cup assembly 200, further cleaning the debris inside the dust cup assembly 200 and preventing incomplete dust collection by the base station 20, which could result in debris residue inside the dust cup assembly 200. Finally, the airflow flows back from the dust cup assembly 200 to the base station 20, thus forming an airflow cycle.

[0075] In this way, in the second state, the airflow generated by the fan assembly 110 can be fully utilized to form an airflow circulation between the dust cup assembly 200, the base station 20, the fan assembly 110, and the duct structure 300, thereby saving energy consumption of the fan assembly 110. Furthermore, the duct structure 300 can guide the airflow from the fan assembly 110 to the dust cup assembly 200, further cleaning debris inside the dust cup assembly 200 and preventing incomplete dust collection in the base station 20, which could result in debris residue inside the dust cup assembly 200.

[0076] Reference Figure 4 , Figure 6 and Figure 7 As shown in the figure, the airflow direction diagrams of the duct structure 300 in the first and second states are respectively displayed. Among them, the arrow pointed to by number a indicates the airflow direction diagram of the duct structure 300 in the first state, and the arrow pointed to by number b indicates the airflow direction diagram of the duct structure 300 in the second state.

[0077] Reference Figures 2 to 4As shown, in some embodiments, the dust cup assembly 200 includes a dust cup body 210 and a filter element 220. The dust cup body 210 is disposed on the device body 100 and is connected to the air duct structure 300 to form a dust collection chamber 211. The filter element 220 is disposed within the dust collection chamber 211. When the air duct structure 300 is in a first state, the filter element 220 is used to filter the airflow entering the fan assembly 110.

[0078] The dust collection chamber 211 can be used to collect debris on the surface to be cleaned. When the air duct structure 300 is in the first state, under the action of the fan assembly 110, the airflow from the external environment and the debris on the surface to be cleaned enter the dust collection chamber 211 together. The airflow passes through the filter element 220 and enters the fan assembly 110, while the debris is blocked by the filter element 220 to prevent hair, dust and other debris from entering the fan assembly 110 and causing damage to the fan assembly 110.

[0079] For example, the filter element 220 can be HEPA, filter cotton, filter screen, etc., and the embodiments of this application do not impose too many restrictions on it.

[0080] Reference Figures 5 to 7 As shown, when the air duct structure 300 is in the second state, the airflow is blown from the fan assembly 110 to the filter element 220 to clean debris from the filter element 220. In this way, the air duct structure 300 can guide the airflow from the fan assembly 110 to the filter element 220 to clean the debris attached to the filter element 220, thereby improving the cleaning efficiency of the cleaning equipment 10 in the subsequent vacuuming state.

[0081] Furthermore, refer to Figures 2 to 4 As shown, the main body 100 of the device is provided with a suction channel 120, and the dust cup body 210 is provided with a suction port 212, which connects the suction channel 120 and the dust collection chamber 211. Thus, when the cleaning device 10 is in suction mode, the suction channel 120 can be aligned with the surface to be cleaned, allowing airflow from the external environment and debris on the surface to pass sequentially through the suction channel 120 and the suction port 212 into the dust collection chamber 211. When the cleaning device 10 is in dust collection mode, the suction channel 120 can be connected to a sealing component on the base station 20 to block the suction channel 120, preventing gas from escaping from the suction channel 120.

[0082] The filter element 220 is located between the dust inlet 212 and the air duct structure 300 to prevent debris from entering the fan assembly 110 directly through the air duct structure 300 via the dust inlet 212.

[0083] Furthermore, refer to Figures 2 to 4As shown, a connecting part 130 is provided on the suction channel 120, which connects the suction channel 120 and the dust cup body 210. The connecting part 130 and the dust cup body 210 can be detachably connected by a threaded structure, a snap-fit ​​structure, etc., to facilitate installation and disassembly.

[0084] Reference Figure 2 As shown, in some embodiments, a dust cup cover 230 is provided on the dust cup body 210. When the dust cup body 210 is docked with the base station 20, the dust cup cover 230 moves relative to the dust cup body 210 to open the dust collection chamber 211.

[0085] In this way, when the dust cup body 210 is connected to the base station 20, the dust collection chamber 211 is opened by the dust cup cover 230 so that the dust collection chamber 211 is connected to the dust collection bin 201 of the base station 20, thereby collecting the debris in the dust collection chamber 211.

[0086] It is understood that the dust cup cover 230 moves relative to the dust cup body 210, and the dust cup cover 230 can open the dust collection chamber 211 by rotating, sliding, or other means. A locking mechanism is provided between the dust cup cover 230 and the dust cup body 210. When the cleaning device 10 is in the vacuuming state, the locking mechanism locks the dust cup cover 230 and the dust cup body 210 to prevent the dust cup cover 230 from opening the dust collection chamber 211 during vacuuming, thus affecting the user experience. When the cleaning device 10 is in the dust collection state, the dust cup cover 230 can abut against the unlocking component on the base station 20, and the unlocking component unlocks the dust cup cover 230 and the dust cup body 210, allowing the dust cup cover 230 to move relative to the dust cup body 210, thereby opening the dust collection chamber 211. The locking mechanism and the unlocking component can adopt existing conventional technologies, which will not be described in detail in this application.

[0087] Reference Figure 2 , Figure 4 and Figure 9 As shown, in some embodiments, the fan assembly 110 includes a fan 111 and a sealing cover 112. The sealing cover 112 is disposed on the main body 100 of the equipment, and the fan 111 is disposed inside the sealing cover 112. The sealing cover 112 is connected to the air duct structure 300. The outer wall of the fan assembly 110, the inner wall of the sealing cover 112 and the air duct structure 300 together form an air outlet channel 113, which is connected to the air outlet 1112 of the fan 111.

[0088] Specifically, refer to Figure 9 As shown, the fan 111 has an air inlet 1111 and an air outlet 1112. Airflow enters the fan 111 through the air inlet 1111 and flows out through the air outlet 1112. The air inlet 1111 is connected to the air duct structure 300, and the air outlet 1112 is connected to the air duct structure 300 through the air outlet channel 113.

[0089] Reference Figure 4 As shown, in the first state, the air outlet duct 113 guides the airflow through the air duct structure 300 to be discharged to the external environment. Thus, when the cleaning equipment 10 is in the dust suction state, the airflow from the external environment enters the dust cup assembly 200, and then flows sequentially through the air duct structure 300, the air inlet 1111 of the fan 111, the air outlet 1112 of the fan 111, and the air outlet duct 113, and finally is discharged to the external environment through the air duct structure 300.

[0090] Reference Figure 6 and Figure 7 As shown, in the second state, the air outlet duct 113 guides the airflow through the air duct structure 300 to blow it toward the dust cup assembly 200. Thus, when the cleaning device 10 is in the dust collection state, the airflow enters the dust collection chamber 201 of the base station 20 from the dust collection chamber 211, and flows back from the dust collection chamber 201 of the base station 20 to the air inlet 1111 of the fan 111, and then flows sequentially through the air outlet 1112 of the fan 111, the air outlet duct 113 and the air duct structure 300, and finally flows back to the dust collection chamber 211 to form an airflow circulation.

[0091] In this way, the fan assembly 110, the sealing cover 112 and the air duct structure 300 together form the air outlet channel 113 to optimize the airflow path and ensure that the air outlet 1112 and the air inlet 1111 of the fan 111 are both connected to the air duct structure 300.

[0092] Reference Figure 9 As shown, in some embodiments, the cleaning device 10 provided in this application also includes a seal 400, which is disposed inside the sealing cover 112 and between the air inlet 1111 of the fan 111 and the air duct structure 300. The air outlet duct 113 is arranged around the periphery of the air inlet 1111 of the fan 111.

[0093] In this way, the air outlet duct 113 is arranged around the periphery of the air inlet 1111 of the fan 111, so that the air inlet 1111 and the air outlet duct 113 can be connected to the air duct structure 300 respectively, making the overall structure more compact. In addition, the gap between the air inlet 1111 and the air duct structure 300 is filled by the sealing element 400 to prevent gas leakage.

[0094] For example, the seal 400 can be annular in structure and fitted around the air inlet 1111. The seal 400 can be made of elastic materials such as silicone gaskets or rubber gaskets. This application embodiment does not impose too many restrictions on this.

[0095] Reference Figure 6 , Figure 14 and Figure 15As shown, in some embodiments, the air duct structure 300 is provided with a connecting channel 305, which is used to interface with the base station 20. In the first state, the connecting channel 305 is connected to the air outlet duct 113, so that the airflow is discharged to the external environment through the air outlet duct 113 and the connecting channel 305 in sequence.

[0096] Thus, when the cleaning equipment 10 is in the vacuuming state, the connecting channel 305 connects the air outlet channel 113 with the external environment, and the airflow flows out from the air outlet 1112 of the fan 111 and is discharged to the external environment through the air outlet channel 113 and the connecting channel 305 in sequence.

[0097] Reference Figure 6 and Figure 7 As shown, in the second state, the connecting channel 305 connects the air inlet 1111 of the ventilator 111 to the base station 20, so that the airflow returns from the base station 20 to the ventilator 111.

[0098] Thus, when the cleaning equipment 10 is in the dust collection state, the airflow flows from the dust collection chamber 201 of the base station 20 to the connecting channel 305, and then to the air inlet 1111 of the fan 111.

[0099] Reference Figure 9 , Figure 12 and Figure 13 As shown, in some embodiments, the air duct structure 300 is provided with a first air duct 301 and a second air duct 302. In the first state, the first air duct 301 connects the air outlet duct 113 and the connecting duct 305, and the second air duct 302 connects the dust collection chamber 211 and the air inlet 1111 of the fan 111.

[0100] Thus, when the cleaning equipment 10 is in the dust collection state, the airflow flows sequentially through the dust collection chamber 211, the second air duct 302, the air inlet 1111 of the fan 111, the air outlet 1112 of the fan 111, the air outlet channel 113, and the first air duct 301, and is finally discharged to the external environment through the connecting channel 305.

[0101] Reference Figure 6 and Figure 7 As shown, in the second state, the first air duct 301 connects the connecting channel 305 and the air inlet 1111 of the fan 111, and the second air duct 302 connects the air outlet channel 113 and the dust collection chamber 211.

[0102] In this way, when the cleaning equipment 10 is in the dust collection state, the gas flows sequentially along the dust collection chamber 211, the dust collection bin 201 of the base station 20, the connecting channel 305, the first air duct 301, the air inlet 1111 of the fan 111, the air outlet 1112 of the fan 111, the air outlet channel 113, and the second air duct 302, and then re-enters the dust collection chamber 211, thereby forming an airflow circulation.

[0103] Reference Figure 9 and Figure 12 As shown, in some embodiments, the air duct structure 300 includes a connecting assembly 310 and a partition 320. Both the first air duct 301 and the second air duct 302 are disposed on the connecting assembly 310, which connects the dust cup body 210 and the fan 111, and together with the dust cup body 210, forms a dust collection chamber 211. The partition 320 is rotatably disposed on the connecting assembly 310, and the partition 320 rotates relative to the connecting assembly 310 to switch between a first state and a second state.

[0104] The connecting component 310 can be connected to the fan assembly 110 on one side and to the dust cup assembly 200 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.

[0105] 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 200 of the cleaning equipment 10, thereby drawing or blowing airflow into the dust cup assembly 200. 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.

[0106] 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.

[0107] 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 200 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 200 to clean it.

[0108] 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. 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 device 10. 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 of the partition 320 changes little, and there is no need to change the position of the connecting component 310, making the air duct structure 300 simple and compact, and the air duct switching more convenient and quick.

[0109] Reference Figure 9 and Figure 10 As shown, in some embodiments, the separator 320 has a first air vent 3211 and a second air vent 3212. In a first state, the first air vent 3211 connects the second air duct 302 to the air inlet 1111 of the fan assembly 110, and the second air vent 3212 connects the first air duct 301 to the air outlet duct 113. In a second state, the first air vent 3211 connects the first air duct 301 to the air inlet 1111 of the fan assembly 110, and the second air vent 3212 connects the second air duct 302 to the air outlet duct 113.

[0110] 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.

[0111] 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.

[0112] Reference Figure 10 As shown, in some embodiments, 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.

[0113] 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.

[0114] 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 10 more balanced, and thus improve the stability and efficiency of the operation of the cleaning equipment 10.

[0115] 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.

[0116] 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.

[0117] In specific implementation, refer to Figure 10 As shown, the separator 320 includes:

[0118] 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.

[0119] 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.

[0120] The dividing body 321 can be a circular piece, the area of ​​which is greater than or equal to the cross-sectional area of ​​the connecting component 310 at the mounting location of the dividing member 320, so that the dividing body 321 can stably separate the first air duct 301, the second air duct 302, the air inlet 303, and the air outlet 304. The dividing body 321 has holes through which the mounting member 330 passes and connects to the connecting component 310, thereby enabling the dividing body 321 to be rotatably connected via the mounting member 330.

[0121] 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.

[0122] Furthermore, in some embodiments, reference is made to Figure 8 and Figure 9 As shown, the connection component 310 includes:

[0123] 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 set on the fan mounting bracket 311.

[0124] The connecting seat 312 is connected to the fan mounting bracket 311 and is used to connect to the dust cup assembly 200. The first air duct 301 and the second air duct 302 are both set on the connecting seat 312.

[0125] 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.

[0126] 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 200. 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.

[0127] 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.

[0128] Among them, reference Figure 9 and Figure 11 As shown, the fan mounting bracket 311 includes:

[0129] The first fixing ring 3111, the inner ring of the first fixing ring 3111 forms the air inlet 303;

[0130] The second fixing ring 3112 is sleeved on the outside of the first fixing ring 3111;

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] Furthermore, referring to Figure 9 , Figure 12 and Figure 13 As shown, the connector 312 includes:

[0137] 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.

[0138] The annular platform 3122 is mounted on the mounting platform 3121, and the first air duct 301 is mounted on the annular platform 3122.

[0139] 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.

[0140] 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.

[0141] Specifically, refer to Figure 9 , Figure 12 and Figure 13As 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.

[0142] The space between two adjacent partition ribs 3124 extends through the mounting platform 3121 to form a second air duct 302;

[0143] The annular platform 3122 has a cavity for communicating with the outside world or the cleaning equipment 10. 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.

[0144] 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.

[0145] 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. The air guide 3125 forms a connecting channel 305 and communicates with 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 communicates with the cavity.

[0146] 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.

[0147] Reference Figure 1 , Figures 5 to 7 As shown, the cleaning system provided in this application includes a base station 20 and any of the cleaning devices 10 described above. The base station 20 has a dust collection chamber 201 and a third air duct 202 connected to each other. The dust collection chamber 201 is used to dock with the dust cup assembly 200 of the cleaning device 10, and the third air duct 202 is used to dock with the air duct structure 300 of the cleaning device 10.

[0148] The third air duct 202 is used to connect with the air guide part 3125 on the air duct structure 300 so that the third air duct 202 is connected to the connecting channel 305.
