Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning systems, in particular to a cleaning base station and a cleaning system. BACKGROUND

[0002] The cleaning device is a kind of intelligent household appliance, which can automatically complete the cleaning work of the surface to be cleaned during walking. For example, the cleaning device can be a robot vacuum cleaner. The cleaning device has a cleaning part and a dust box. During walking, the cleaning device can suck impurities on the surface to be cleaned into the dust box for temporary storage, and clean the surface to be cleaned through the cleaning part.

[0003] When the cleaning device returns to the cleaning base station after completing the cleaning task, the cleaning parts of the cleaning device, including the dust box and the cleaning part, are self-cleaned and dried in the cleaning base station. However, in order to realize the self-cleaning and drying of the dust box of the cleaning device and the drying of the cleaning part in the current cleaning base station, multiple separate channels are provided in the cleaning base station, which causes a large number of channels in the cleaning base station. Invention content

[0004] The cleaning base station and the cleaning system provided by the embodiments of the present application can reduce the number of channels in the cleaning base station, and selectively perform self-cleaning and drying of the cleaning part on the basis of self-cleaning of the dust box, or selectively perform self-cleaning and drying of the cleaning part while drying the dust box and the parts in the dust box.

[0005] In a first aspect, the embodiments of the present application provide a cleaning base station, comprising:

[0006] The base station comprises a dust collection container and a dust collection fan. The dust collection container is configured to communicate with one side of a dust box in a cleaning device. The dust collection fan has a suction port and an air outlet. The suction port communicates with the dust collection container.

[0007] The air duct assembly comprises an air duct part. The air duct part has a first communication port, a second communication port and a third communication port. The air outlet communicates with the third communication port. The first communication port is configured to communicate with the other side of the dust box. The second communication port communicates with the cleaning part in the cleaning device.

[0008] The cleaning base station has a dust collection mode. In the dust collection mode:

[0009] The dust collection fan is configured to vacuum the dust collection container through the suction port, and output air flow to the third communication port through the air outlet. The third communication port communicates with the first communication port, so that the air flow output by the third communication port is blown to the dust box through the first communication port. The second communication port is configured to selectively communicate with the third communication port, so that the air flow output by the third communication port is blown to the cleaning part through the second communication port.

[0010] The dust collection mode is used to suck the garbage in the dust box into the dust container, so as to realize the self-cleaning of the dust box, reduce the cleaning frequency of the dust box by the user, and improve the user experience.

[0011] In addition, by being configured to selectively communicate with the third communication port, the cleaning base station can selectively communicate the second communication port with the third communication port when the dust box is self-cleaned in the dust collection mode, so that the air flow generated by the dust collection fan can also blow away at least part of the garbage remaining on the cleaning element when passing through the cleaning element, so as to self-clean and dry the cleaning element, thereby enhancing the flexibility of the cleaning base station in the dust collection mode, and improving the user experience.

[0012] In the dust collection mode, when the second communication port communicates with the third communication port, the air duct piece can be used as a self-cleaning and drying channel of the cleaning element in addition to being used as an air outlet duct of the dust collection fan and a self-cleaning channel of the dust box, so that the function of the air duct piece is more diversified, and the number of channels in the cleaning base station can be reduced.

[0013] In some embodiments, the first communication port is configured to communicate with a cavity at the top of the dust box, and the cavity is surrounded by the box body of the dust box and the filter element located in the box body. In this way, in the dust collection mode, the air flow generated by the dust collection fan can be blown from the top of the dust box to the filter element through the first communication port, so that the garbage remaining on the filter element can be blown into the dust box, and when the dust collection fan is used to suck the garbage in the dust container, the garbage blown into the dust box from the filter element can be temporarily stored in the dust container, thereby reducing the cleaning frequency of the filter element by the user and improving the user experience.

[0014] In some embodiments, in the dust collection mode:

[0015] The communication state of the second communication port and the third communication port is configured to periodically change, and the communication state of the second communication port and the third communication port includes a first period and a second period in a change period; in the first period, the second communication port does not communicate with the third communication port; in the second period, the second communication port communicates with the third communication port.

[0016] Thus, in the first time period, the airflow generated by the dust collection fan can only pass through the first communication port to blow into the filter and the box body of the dust box, so that the garbage remaining on the filter can be blown into the dust box and temporarily stored in the dust collection container. In the second time period, part of the airflow generated by the dust collection fan will pass through the first communication port to blow into the filter and the box body of the dust box, and the remaining airflow generated by the dust collection fan will be divided by the second communication port, so that the divided airflow will blow to the cleaning element to perform self-cleaning and drying treatment on the cleaning element, thereby avoiding the waste of the airflow generated by the dust collection fan in the second time period.

[0017] In addition, in the second time period, the airflow flow rate and the force generated by the airflow (such as the wind force) blowing into the filter and the dust box can be reduced, so as to avoid the airflow generated by the dust collection fan from continuously and massively blowing into the filter, thereby ensuring that the garbage in the dust box can be smoothly sucked into the dust collection container to achieve self-cleaning of the dust box.

[0018] In addition, by controlling the time ratio of the second time period in a change cycle in the dust collection mode, the cleaning base station can adjust the self-cleaning efficiency and effect of the dust box, the filter in the dust box, and the cleaning element.

[0019] In some embodiments, the first communication port is located at one end of the air duct element, the second communication port and the third communication port are both located at the other end of the air duct element, and the second communication port is located downstream of the third communication port in the direction of the airflow output by the third communication port, so that most of the airflow output by the dust collection fan through the third communication port can blow to the cleaning element through the second communication port, thereby enhancing the diversion effect of the second communication port to further reduce the airflow flow rate and the force generated by the airflow blowing into the filter and the dust box in the second time period.

[0020] In some embodiments, the cleaning base station further comprises a hot air assembly, the air duct element further has a fourth communication port, and the hot air assembly is arranged at the fourth communication port; the cleaning base station has a drying mode, and in the drying mode:

[0021] The hot air assembly is configured to output hot airflow to the fourth communication port, the first communication port is in communication with the fourth communication port, the second communication port is selectively in communication with the fourth communication port, and the second communication port is not in communication with the third communication port.

[0022] Thus, the air duct element simultaneously interfaces with the dust collection fan and the hot air assembly. At this time, the cleaning base station can autonomously select to perform self-cleaning or drying treatment on any one of the dust box and the cleaning element, and the cleaning base station can share one air duct element in the dust collection mode and the drying mode, thereby saving the space occupied by the air duct element in the cleaning base station and facilitating the miniaturization of the cleaning base station.

[0023] And, since the second communication port is not communicated with the third communication port in the drying mode, the hot air generated by the hot air assembly can be prevented from flowing to the dust collecting fan through the third communication port, so that the loss of the hot air is avoided, and the drying effect of the cleaning base on the dust box and the self-cleaning and drying effect on the cleaning element are ensured in the drying mode.

[0024] In some embodiments, the hot air assembly comprises a drying fan and a heating element, the drying fan is located outside the air duct element and is configured to make the external airflow of the air duct element enter the fourth communication port;

[0025] The heating element is located on the air outlet side of the drying fan and is configured to heat the external airflow to form a hot airflow.

[0026] In this way, the hot air assembly can convert the external airflow of the air duct element into a hot airflow and output the hot airflow to the fourth communication port, so that the self-cleaning and drying treatment of the cleaning element can be realized while the dust box is dried.

[0027] In some embodiments, the fourth communication port and the second communication port are located on opposite sides of the air duct element, and the projection of the fourth communication port on the opposite side of the air duct element overlaps with the second communication port.

[0028] In this way, when the cleaning base sets an air duct switching element between the second communication port and the fourth communication port of the air duct element, the second communication port can be selectively communicated with the fourth communication port.

[0029] In some embodiments, the air duct element comprises a first sub-air duct and a second sub-air duct in communication, the air duct wall of the first sub-air duct has a first communication port and a third communication port;

[0030] The air duct wall of the second sub-air duct has a second communication port, which is configured to be selectively communicated with the first sub-air duct, so that in the dust collecting mode, the second communication port can be communicated with the third communication port through the first sub-air duct.

[0031] In some embodiments, the air duct assembly further comprises an air duct switching element, which is movably arranged in the second sub-air duct;

[0032] The air duct switching element is configured to selectively communicate the second communication port with the first sub-air duct when it moves in the air duct element, so that when the air duct switching element communicates the second communication port with the first sub-air duct, the second communication port can be communicated with the third communication port through the first sub-air duct.

[0033] In some embodiments, the second sub-air duct has a rotating cavity, and the air duct switching element is rotatably arranged in the rotating cavity;

[0034] The air duct switching piece is configured to selectively communicate the second communication port with the first sub-air duct when rotating in the second sub-air duct. In this way, while the air duct switching piece is arranged in the second sub-air duct, the second communication port can be selectively communicated with the first sub-air duct by rotating the air duct switching piece in the rotating cavity.

[0035] In some embodiments, the air duct switching piece has a communication channel therein, and has an open position and a closed position when rotating in the rotating cavity;

[0036] When the air duct switching piece is in the open position, the communication channel communicates the second communication port and the first sub-air duct, so that the second communication port is communicated with the first sub-air duct;

[0037] When the air duct switching piece is in the closed position, both ends of the communication channel are blocked by the cavity wall of the rotating cavity, so that the second communication port is not communicated with the first sub-air duct.

[0038] In some embodiments, the shape of the air duct switching piece matches the shape of the rotating cavity, so that when the air duct switching piece rotates in the rotating cavity, both ends of the communication channel can be blocked by the cavity wall of the rotating cavity when the air duct switching piece rotates to the closed position.

[0039] In some embodiments, the communication channel has an inlet end and an outlet end, and the caliber of the communication channel gradually increases in the direction from the inlet end to the outlet end;

[0040] When the air duct switching piece is in the open position, the inlet end is communicated with the first sub-air duct, and the outlet end is communicated with the second communication port, so that most of the airflow in the air duct can enter the communication channel through the inlet end, and blow towards the cleaning piece through the second communication port, improving the self-cleaning and drying efficiency of the cleaning piece, and further enhancing the shunting effect of the second communication port in the dust collection mode, reducing the airflow flow and the force generated by the airflow blowing towards the filter piece and the dust box.

[0041] In some embodiments, the air duct assembly further comprises a control piece connected with the air duct switching piece and configured to control the rotation of the air duct switching piece, so that the air duct switching piece rotates in different directions under the control of the control piece, thereby realizing switching between the open position and the closed position.

[0042] In some embodiments, the air duct assembly further comprises a first air blocking piece located in the first sub-air duct opposite the third communication port, and the first air blocking piece is rotationally connected with the air duct wall of the first sub-air duct to open or close the third communication port when rotating.

[0043] The first wind blocking piece is rotationally connected with the wind channel wall of the first sub-wind channel, so that the communication state between the wind channel piece and the dust collection fan is controlled by rotation of the first wind blocking piece to open or close the third communication port. In this way, when the wind channel piece is in communication with the dust collection fan, the airflow generated by the dust collection fan can achieve self-cleaning and drying treatment of the dust box and the cleaning piece in the dust collection mode. When the cleaning base station is in other working modes (such as the drying mode), the wind channel piece can not be in communication with the dust collection fan to avoid affecting the normal operation of the cleaning base station in other working modes.

[0044] In some embodiments, in the dust collection mode, the first wind blocking piece is configured to rotate towards the first sub-wind channel under the push of the airflow output by the third communication port to open the third communication port.

[0045] In this way, while achieving the communication between the wind channel piece and the dust collection fan, compared with the way of setting an additional driving device in the wind channel piece to drive the rotation of the first wind blocking piece, the structure of the wind channel assembly can be simplified and the cost of the cleaning system can be reduced.

[0046] In some embodiments, the wind channel assembly further comprises a torsion spring and a rotating shaft, the rotating shaft is rotationally arranged on the wind channel wall of the first sub-wind channel at a position opposite to the third communication port;

[0047] The first wind blocking piece is connected to one side of the rotating shaft adjacent to the third communication port; the torsion spring is arranged on the rotating shaft, one end of the torsion spring abuts against the wind channel wall of the first sub-wind channel, and the other end of the torsion spring abuts against the first wind blocking piece.

[0048] In this way, on the basis of the rotational connection between the first wind blocking piece and the wind channel wall of the first sub-wind channel, when the airflow is output by the third communication port, the airflow will push the first wind blocking piece to rotate around the rotating shaft towards the first sub-wind channel to open the third communication port, at this time, the torsion spring will be deformed. When the third communication port does not output airflow, the torsion spring will generate a rebound force to drive the first wind blocking piece to rotate around the rotating shaft towards the side of the third communication port to close the third communication port, thereby achieving automatic resetting of the first wind blocking piece.

[0049] In some embodiments, the wind channel assembly further comprises a second wind blocking piece, the second wind blocking piece is located in the first sub-wind channel adjacent to the first communication port, and the second wind blocking piece is rotationally connected with the wind channel wall of the first sub-wind channel to open or close the first communication port when rotating.

[0050] The second wind blocking piece is rotationally connected with the wind channel wall of the first sub-wind channel, so that the communication state between the dust box and components such as the dust collection fan is controlled by rotation of the second wind blocking piece to open or close the first communication port. In this way, when the dust box is in communication with the dust collection fan through the wind channel piece, the airflow generated by the dust collection fan can achieve self-cleaning treatment of the dust box in the dust collection mode.

[0051] In some embodiments, the second wind shield is a flexible wind shield, and the second wind shield is configured to be deformed and rotated under the pushing of the airflow in the first sub-air duct to open or close the first communication port.

[0052] In this way, the structure of the air duct assembly can be simplified and the cost of the cleaning system can be reduced by realizing the communication between the air duct member and the dust collection fan without using an additional driving device to drive the second wind shield to rotate.

[0053] In some embodiments, the dust collection base station further comprises a dust collection air duct arranged between the dust collection container and the dust box to communicate one side of the dust collection container and the dust box, so that the dust collection container can communicate the one side of the dust box through the dust collection air duct.

[0054] In a second aspect, the embodiments of the present application further provide a cleaning base station, comprising:

[0055] a base station;

[0056] an air duct assembly comprising an air duct member, the air duct member having a first communication port, a second communication port and a fourth communication port, the first communication port being configured to communicate with the dust box, the second communication port being configured to communicate with a cleaning member in the cleaning device, and the fourth communication port being configured to communicate with a hot air assembly.

[0057] a hot air assembly arranged at the fourth communication port;

[0058] The cleaning base station has a drying mode, and in the drying mode:

[0059] the hot air assembly is configured to output a hot airflow to the fourth communication port, the first communication port is in communication with the fourth communication port, and the second communication port is selectively in communication with the fourth communication port.

[0060] In the drying mode, the first communication port is in communication with the fourth communication port, so that the hot air assembly can communicate with the dust box through the air duct member. In this way, the hot airflow generated by the hot air assembly can enter the dust box through the first communication port after passing through the fourth communication port, so as to dry the dust box and the components (such as the filter member) in the dust box.

[0061] In addition, in the drying mode, the second communication port is selectively in communication with the fourth communication port, so that the cleaning base station can dry the dust box and the components in the dust box in the drying mode, and can also selectively communicate the second communication port with the fourth communication port, so that the hot air assembly can communicate with the cleaning member through the air duct member. In this way, at least part of the garbage remaining on the cleaning member can be blown away by the hot airflow generated by the hot air assembly when passing through the cleaning member, so as to clean and dry the cleaning member, thereby enhancing the flexibility of the cleaning base station in the drying mode. At the same time, the drying efficiency and effect of the dust box and the cleaning member can be adjusted by controlling the communication time of the second communication port and the fourth communication port, thereby improving the user experience.

[0062] In drying mode, when the second and fourth connecting ports are connected, the air duct component, in addition to serving as the air outlet duct of the hot air assembly and the drying channel of the dust box, can also be used as a self-cleaning and drying channel for the cleaning components, making the function of the air duct component more diversified. Compared with existing cleaning base stations, the embodiments of this application, through the setting of this multifunctional air duct structure, can reduce the number of channels within the cleaning base station.

[0063] In addition, the embodiments of this application only require one hot air assembly to dry the dust box and cleaning parts, which reduces the number of hot air assemblies compared to existing cleaning systems.

[0064] In some embodiments, the hot air assembly includes a drying fan and a heating element, the drying fan being located outside the air duct and configured to allow external airflow from the air duct to enter a fourth communication port.

[0065] The heating element is located on the outlet side of the drying fan and is configured to heat the external airflow so that the external airflow becomes a hot airflow.

[0066] In this way, the hot air assembly can convert the external airflow of the air duct into hot airflow and output the hot airflow to the fourth connection port, thereby achieving both drying of the dust box and self-cleaning and drying of the cleaning components.

[0067] In some embodiments, the air duct assembly further includes an air duct switching component, which is movably disposed within the air duct and located between the second connection port and the fourth connection port.

[0068] The duct switching component is configured to selectively connect the second connection port to the fourth connection port when moving within the duct component.

[0069] By moving the air duct switching component within the air duct, the connection status between the second and fourth connecting ports can be controlled. This allows the second and fourth connecting ports to be connected by moving the air duct switching component when the cleaning component needs to be self-cleaned and dried in the drying mode, so that hot air flows towards the cleaning component.

[0070] Furthermore, since the air duct switching component is located between the second and fourth connecting ports, when the air duct switching component moves to connect the second and fourth connecting ports, the second and fourth connecting ports are opposite each other, so that most of the hot airflow output from the fourth connecting port will flow to the cleaning component through the second connecting port, thereby improving the drying effect of the cleaning component.

[0071] In drying mode, if only the dust box needs to be dried, the second connecting port can be disconnected from the fourth connecting port by using the movable air duct switching component, so that the hot airflow can flow into the dust box.

[0072] In a third aspect, the embodiments of the present application further provide a cleaning system, comprising the cleaning device and the cleaning base station according to any one of the above, the cleaning device having the dust box and the cleaning element therein, and the cleaning base station comprising the dust collecting container and the air duct element, the dust collecting container being in communication with one side of the dust box, and the first communication port of the air duct element being in communication with the other side of the dust box;

[0073] The second communication port of the air duct element is in communication with the cleaning element.

[0074] The cleaning system of the present application has the effects of the cleaning base station described above, and will not be repeated here. BRIEF DESCRIPTION OF DRAWINGS

[0105] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0106] The embodiments of the present application provide a cleaning system. The cleaning system comprises a cleaning device and a cleaning base station. The cleaning device can comprise a sweeping robot, a scrubber, or the like cleaning device capable of automatically cleaning a to-be-cleaned surface. The to-be-cleaned surface can be a ground or the like.

[0107] The following will take the sweeping robot as an example to further describe the structure of the cleaning system.

[0108] The cleaning device is internally provided with a dust box and a cleaning element. The sweeping robot can suck impurities on the to-be-cleaned surface into the dust box for temporary storage during walking, and clean the to-be-cleaned surface by contacting and rubbing the to-be-cleaned surface through the cleaning element. For example, the impurities on the to-be-cleaned surface can comprise dust and the like. The cleaning element can comprise a cloth or the like. The dust box is further provided with a filter element, which can filter the impurities entering the dust box. After the filter element filters the impurities, some impurities will remain on the filter element, and the impurities passing through the filter element will be temporarily stored in the dust box.

[0109] It should be noted that the setting positions of the dust box and the cleaning element in the cleaning device can be determined according to the structure of the existing sweeping robot, and will not be further described in the embodiments of the present application.

[0110] Figure 1 And Figure 2 The structure schematic diagrams of a cleaning system under different visual angles are shown. Among them, Figure 1 And Figure 2 The cleaning device 400 in the cleaning system shown in the above

[0111] Referring to Figure 1 And Figure 2 The cleaning system further comprises a cleaning base station 100. After the cleaning device 400 cleans the to-be-cleaned surface, the cleaning device 400 can return to the cleaning base station 100, and the cleaning base station 100 can perform self-cleaning and drying treatment on the dust box 410 in the cleaning device 400, and perform drying treatment on the cleaning element in the cleaning device 400.

[0112] However, in order to realize the self-cleaning and drying treatment of the dust box and the drying treatment of the cleaning piece in the current cleaning base station, multiple independent channels are arranged in the cleaning base station. These channels include a dust collection fan outflow channel, a cleaning piece self-cleaning channel, a dust box drying channel and a cleaning piece drying channel. These channels are separated from each other and have single functions, which causes a large number of channels in the cleaning base station.

[0113] Therefore, the embodiment of the present application provides a cleaning base station, and a wind channel member is arranged in the cleaning base station. The wind channel member is a multifunctional wind channel member, and has multiple communication ports, so that the wind channel member can be in communication with the dust box and the cleaning piece, and the wind channel member can also be in communication with at least one of the dust collection fan and the hot air assembly, so that the function of the wind channel member is more diversified, and the number of channels in the cleaning base station is reduced.

[0114] When the wind channel member is in communication with the dust collection fan and the cleaning base station is in the dust collection mode, the wind channel member can selectively communicate the dust collection fan with the cleaning piece while communicating the dust collection fan with the dust box, so that the cleaning base station can autonomously and selectively perform the self-cleaning and drying treatment on the cleaning piece when performing the self-cleaning treatment on the dust box, thereby enhancing the flexibility of the cleaning base station in the dust collection mode, and the wind channel member can be used as the self-cleaning channel of the dust box and the self-cleaning and drying channel of the cleaning piece.

[0115] When the wind channel member is in communication with the hot air assembly and the cleaning base station is in the drying mode, the wind channel member can selectively communicate the hot air assembly with the cleaning piece while communicating the hot air assembly with the dust box, so that the cleaning base station can autonomously and selectively perform the drying treatment on the cleaning piece when performing the drying treatment on the dust box, thereby enhancing the flexibility of the cleaning base station in the drying mode, and the wind channel member can be used as the drying channel of the dust box and the self-cleaning and drying channel of the cleaning piece.

[0116] In addition, when the wind channel member is in communication with the dust collection fan and the hot air assembly, the cleaning base station can autonomously select to perform the self-cleaning treatment or the drying treatment on any one of the dust box and the cleaning piece, and the cleaning base station can share the wind channel member in the dust collection mode and the drying mode, so that the space occupied by the wind channel member in the cleaning base station is saved, and the miniaturization of the cleaning base station is facilitated.

[0117] Figure 3 A partial exploded view of a cleaning system provided by the embodiment of the present application is shown, Figure 4 A simple view of a cleaning system provided by the embodiment of the present application is shown.

[0118] The following will be described in combination with Figures 1 to 4 The structure of the cleaning base station 100 will be further described.

[0119] Referring to Figures 1 to 4The cleaning base station 100 comprises a base station 10, the base station 10 comprising a dust collection container 11, a dust collection air duct 30 and a dust collection air blower 12. For example, the dust collection container 11 can be a dust bucket, a dust bag or the like. The dust collection air duct 30 is arranged between the dust collection container 11 and a dust box 410 in the cleaning device 400, and communicates one side of the dust collection container 11 with the dust box 410. The dust collection air blower 12 has a suction port and an air outlet, the suction port being in communication with the dust collection container 11, so that the dust collection air blower 12 can vacuum the dust collection container 11 through the suction port.

[0120] Referring to Figure 3 The cleaning base station 100 further comprises an air duct assembly comprising an air duct piece 20. The air duct piece 20 has a plurality of communication ports. The plurality of communication ports comprises a first communication port 21, a second communication port 22 and a third communication port 23. The air outlet communicates with the third communication port 23, so that the air duct piece 20 communicates with the dust collection air blower 12, so that the generated air flow can be output to the air duct piece 20 through the air outlet and the third communication port 23.

[0121] Referring to Figure 3 The first communication port 21 is configured to communicate with the dust box 410. Specifically, the first communication port 21 is configured to communicate with the other side of the dust box 410. The second communication port 22 communicates with a cleaning piece in the cleaning device 400, so that the air duct piece 20 communicates with the cleaning piece, so that the air duct piece 20 can deliver air flow to the cleaning piece through the second communication port 22. Specifically, the second communication port 22 can communicate with the cleaning piece through a channel in the cleaning device 400, which can be a drying channel in the cleaning device 400.

[0122] The cleaning base station 100 has a dust collection mode, in which:

[0123] The dust collection air blower 12 is configured to vacuum the dust collection container 11 through the suction port, and output air flow to the third communication port 23 through the air outlet, the third communication port 23 communicating with the first communication port 21, so that the air flow output by the third communication port 23 is blown to the dust box 410 through the first communication port 21.

[0124] In this way, in the dust collection mode, the dust collection air blower 12 communicates with the dust box 410 through the air duct piece 20, so that the dust collection container 11, the dust collection air blower 12, the air duct piece 20 and the dust box 410 are communicated to form a dust collection loop, and the air flow generated by the dust collection air blower 12 can flow in the air flow loop, the flow direction can be seen from the direction of the dashed arrow in Figure 4 Due to the vacuuming of the dust collection container 11 by the dust collection air blower 12, the dust collection container 11 is in a negative pressure state, and the garbage in the dust box 410 can be temporarily sucked into the dust collection container 11, so as to realize self-cleaning of the dust box 410, reduce the cleaning frequency of the dust box 410 by the user, and improve the user experience.

[0125] And, in the dust collection mode:

[0126] The second communication port 22 is configured to selectively communicate with the third communication port 23, so that the air flow output by the third communication port 23 is blown to the cleaning element through the second communication port 22. That is, in the dust collection mode, the cleaning base station 100 can selectively communicate the second communication port 22 with the third communication port 23, or can also selectively communicate the second communication port 22 with the third communication port 23. When the second communication port 22 is communicated with the third communication port 23, the dust collection fan 12 can be communicated with the cleaning element through the air duct 20.

[0127] By configuring the second communication port 22 to selectively communicate with the third communication port 23, the cleaning base station 100 can selectively communicate the second communication port 22 with the third communication port 23 while performing self-cleaning of the dust box 410 in the dust collection mode, so that the dust collection fan 12 can be communicated with the cleaning element through the air duct 20, so that at least part of the garbage remaining on the cleaning element can be blown away when the air flow generated by the dust collection fan 12 passes through the cleaning element, so as to perform self-cleaning and drying of the cleaning element. This can enhance the flexibility of the cleaning base station 100 in the dust collection mode, and can also select to perform self-cleaning and drying of the cleaning element in the dust collection mode, thereby improving user experience.

[0128] In the dust collection mode, when the second communication port 22 is not communicated with the third communication port 23, the air duct 20 can be used as an air outlet duct of the dust collection fan 12 and a self-cleaning channel of the dust box 410. In the dust collection mode, when the second communication port 22 is communicated with the third communication port 23, the air duct 20 can be used as a self-cleaning and drying channel of the cleaning element in addition to being used as an air outlet duct of the dust collection fan 12 and a self-cleaning channel of the dust box 410, so that the function of the air duct 20 is more diversified. Compared with the existing cleaning base station 100, the air duct 20 of the present application can reduce the number of channels in the cleaning base station 100.

[0129] Figure 5 A structure diagram of the dust box 410 and the air duct 20 is shown.

[0130] Referring to Figure 5 The dust box 410 generally includes a box body 411 and a filter element 412 located in the box body 411. The filter element 412 can also be referred to as a Hepa, which is used to filter garbage entering the dust box 410. After passing through the filter element 412, part of the garbage will remain on the filter element 412. The installation method of the filter element 412 in the dust box 410 can be determined according to the structure of the existing sweeping robot, which will not be described in detail in the present application.

[0131] Referring to Figure 5In some embodiments, the first communication port 21 can be configured to communicate with the cavity 413 at the top of the dust box 410, which is enclosed by the box body 411 of the dust box 410 and the filter 412 located in the box body 411. In this way, in the dust collection mode, the airflow generated by the dust collection fan 12 can be blown from the top of the dust box 410 to the filter 412 through the first communication port 21, so that the garbage remaining on the filter 412 can be blown into the dust box 410, and when the dust collection fan 12 is vacuuming the dust collection container 11, the garbage blown into the dust box 410 on the filter 412 can be temporarily sucked into the dust collection container 11, reducing the frequency of cleaning the filter 412 by the user, and providing a user experience.

[0132] It should be understood that, in order to facilitate the communication between the first communication port 21 and the cavity 413 at the top of the dust box 410, the box body 411 of the dust box 410 has a through port at the top, so that the first communication port 21 communicates with the cavity 413 at the top of the dust box 410 through the through port.

[0133] If the airflow generated by the dust collection fan 12 continues to blow a large amount of air to the filter 412, it will affect the garbage in the dust box 410 being sucked into the dust collection container 11.

[0134] Figures 6 to 8 The structural schematic diagrams of the air duct assembly at different viewing angles in the first state are shown.

[0135] To this end, see Figures 6 to 8 In some embodiments, in the dust collection mode:

[0136] The communication state of the second communication port 22 and the third communication port 23 is configured to change periodically, and the communication state of the second communication port 22 and the third communication port 23 includes a first period and a second period in a change period; in the first period, the second communication port 22 is not in communication with the third communication port 23; in the second period, the second communication port 22 is in communication with the third communication port 23. The first period and the second period form an operating cycle of the dust collection fan 12.

[0137] Since in the dust collection mode, the third communication port 23 communicates with the first communication port 21, when the second communication port 22 does not communicate with the third communication port 23 in the first period, the airflow generated by the dust collection fan 12 can only be blown into the filter 412 and the box body 411 of the dust box 410 through the first communication port 21, so that the garbage remaining on the filter 412 can be blown into the dust box 410 and can be temporarily sucked into the dust collection container 11.

[0138] When in the second time period, due to the second communication port 22 and the third communication port 23 are communicated, at this time, the first communication port 21 and the second communication port 22 are both communicated with the third communication port 23, part of the airflow generated by the dust collection fan 12 will be blown to the filter 412 and the box body 411 of the dust box 410 through the first communication port 21, and the rest of the airflow generated by the dust collection fan 12 will be shunted by the second communication port 22, so that the shunted part of the airflow will be blown to the cleaning element.

[0139] In this way, when the communication state of the second communication port 22 and the third communication port 23 is periodically changed, and in the second time period, the airflow flow and the force generated by the airflow (such as the wind force) blowing to the filter 412 and the dust box 410 can be reduced, so as to avoid the airflow generated by the dust collection fan 12 continuously and in large quantities blowing to the filter 412, so as to ensure that the garbage in the dust box 410 can be smoothly sucked into the dust collection container 11, and the self-cleaning process of the dust box 410 is realized. At this time, the self-cleaning process of the dust box 410 includes the self-cleaning process of the residual garbage on the filter 412, and also includes the self-cleaning process of the part of the garbage temporarily stored in the box body 411 and filtered by the filter 412.

[0140] The cleaning base station 100 can adjust the self-cleaning efficiency and effect of the dust box 410, the filter 412 in the dust box 410 and the cleaning element by controlling the time ratio of the second time period in a change period in the dust collection mode.

[0141] For example, the first time period can be less than the second time period, for example, taking a running period of 10s as an example, the first time period can be 2s, and the first time period can be 8s. Alternatively, the first time period can also be greater than the second time period.

[0142] The change period, the first time period and the second time period can be flexibly set according to the requirements of the cleanliness of the dust box 410 and the cleanliness of the cleaning element, and the size of the change period, the first time period and the second time period is not limited in the present application.

[0143] In addition, since the shunted part of the airflow will blow to the cleaning element, at least part of the residual on the cleaning element will be blown away when the airflow passes through the cleaning element, so that the airflow flow can accelerate the evaporation of the moisture on the cleaning element, the cleaning element can be dried, and the waste of the airflow generated by the dust collection fan 12 in the second time period is avoided.

[0144] Referring to Figure 6In some embodiments, the first connecting port 21 can be located at one end of the air duct component 20, and the second connecting port 22 and the third connecting port 23 can both be located at the other end of the air duct component 20, so that the second connecting port 22 is closer to the third connecting port 23. Furthermore, along the direction of the airflow output from the third connecting port 23, the second connecting port 22 is located downstream of the third connecting port 23. In this way, most of the airflow output by the dust collecting fan 12 through the third connecting port 23 can be blown towards the cleaning component through the second connecting port 22, enhancing the diversion effect of the second connecting port 22. This further reduces the airflow flow rate and the force generated by the airflow blowing towards the filter element 412 and the dust box 410 during the second time period, ensuring that the debris in the dust box 410 can be smoothly sucked into the dust collection container 11. At the same time, it increases the airflow flow rate towards the cleaning component, making reasonable use of the airflow generated by the dust collecting fan 12 and enhancing the self-cleaning and drying effect on the cleaning component.

[0145] See Figure 6 and Figure 7 The air duct component 20 includes a first sub-air duct 25 and a second sub-air duct 26 that are connected to each other. The first sub-air duct 25 and the second sub-air duct 26 are air ducts extending in two different directions. The air duct wall of the first sub-air duct 25 has a first connecting opening 21 and a third connecting opening 23. The air duct wall of the second sub-air duct 26 has a second connecting opening 22.

[0146] The second connection port 22 is configured to selectively connect with the first sub-duct 25 so that in dust collection mode, the second connection port 22 can connect with the third connection port 23 through the first sub-duct 25.

[0147] Figure 9 An exploded view of a duct assembly provided in an embodiment of this application.

[0148] See Figure 9 The air duct component 20 may include an upper air duct cover 27, a lower air duct cover 28, and an air duct base 29. The upper air duct cover 27 is located on top of the lower air duct cover 28, and the air duct base 29 is located at the bottom of the lower air duct cover 28. Both the upper air duct cover 27 and the air duct base 29 are connected to the lower air duct cover 28, and these three together form the air duct component 20. Specifically, the upper air duct cover 27 and part of the lower air duct cover 28 form a first sub-air duct 25, and the air duct base 29 and the remaining lower air duct cover 28 form a second sub-air duct 26.

[0149] See Figure 9As an example, the first opening 271 is provided on the air duct upper cover 27 and the air duct lower cover 28, and the two first openings 271 are connected to form the first communication port 21. The second opening 281 is provided on the air duct lower cover 28 and the air duct base 29, and the two second openings 281 are connected to form the second communication port 22. The third communication port 23 is provided on the side of the air duct upper cover 27 adjacent to the second communication port 22, so that the third communication port 23 and the second communication port 22 are located at the same end of the air duct 20, and the second communication port 22 is located downstream of the third communication port 23 along the direction of the airflow output by the third communication port 23.

[0150] Referring to Figure 9 In some embodiments, the air duct assembly can further include a plurality of sealing members 40. For example, the sealing member 40 can be a sealing ring. The air duct 20 is provided with the sealing member 40 at the position of at least part of the communication port, so that when the communication port is connected to other components in the cleaning system, the leakage of the airflow at the connection between the communication port and the other components can be avoided. For example, the communication port provided with the sealing member 40 can include the first communication port 21 and the second communication port 22, etc.

[0151] Figure 10 A cross-sectional view of the air duct assembly in the A-A direction is shown in Figure 8 A cross-sectional view of the air duct assembly in the A-A direction is shown in Figure 11 A structural schematic view of an air duct assembly is shown when the air duct assembly is in a second state, Figure 12 A cross-sectional view of the air duct assembly in the B-B direction is shown in Figure 11 A cross-sectional view of the air duct assembly in the B-B direction is shown in

[0152] Referring to Figure 10 and Figure 12 and in combination with Figure 11 In some embodiments, the air duct assembly further includes an air duct switching member 50 located in the air duct 20. The air duct switching member 50 is movably arranged in the air duct 20. For example, the air duct switching member 50 is movably arranged in the second sub-air duct 26. The air duct switching member 50 is configured to selectively connect the second communication port 22 with the first sub-air duct 25 when the air duct switching member 50 is moved in the air duct 20, so that when the air duct switching member 50 connects the second communication port 22 with the first sub-air duct 25, the second communication port 22 can be connected to the third communication port 23 through the first sub-air duct 25.

[0153] wherein, Figure 10 is a structural view of the second communication port 22 not connected to the first sub-air duct 25, Figure 12 is a structural view of the second communication port 22 connected to the first sub-air duct 25.

[0154] Referring to Figure 10 and Figure 12The second sub-air duct 26 has a rotating cavity 261, and the air duct switching piece 50 is arranged in the rotating cavity 261. The air duct switching piece 50 is configured to selectively communicate the second communication port 22 with the first sub-air duct 25 when the air duct switching piece 50 rotates in the second sub-air duct 26. In this way, the air duct switching piece 50 is arranged in the second sub-air duct 26, and the second communication port 22 is selectively communicated with the first sub-air duct 25 by rotating the air duct switching piece 50 in the rotating cavity 261.

[0155] It should be noted that the air duct switching piece 50 can also be arranged in the second sub-air duct 26 by linear motion or other non-rotating manner to selectively communicate the second communication port 22 with the first sub-air duct 25.

[0156] Hereinafter, the air duct switching piece 50 is arranged in the rotating cavity 261 by rotation as an example to further describe the structure of the air duct assembly and the cleaning system.

[0157] Referring to Figure 10 and Figure 12 The air duct switching piece 50 has a communication passage 51, and the air duct switching piece 50 has an open position and a closed position when rotating in the rotating cavity 261.

[0158] Referring to Figure 10 When the air duct switching piece 50 is in the open position, the communication passage 51 communicates the second communication port 22 and the first sub-air duct 25, so that the second communication port 22 is communicated with the first sub-air duct 25.

[0159] When the air duct switching piece 50 is in the closed position, the two ends of the communication passage 51 are blocked by the cavity wall of the rotating cavity 261, so that the second communication port 22 is not communicated with the first sub-air duct 25.

[0160] Therefore, when the air duct switching piece 50 is switched between the open position and the closed position by rotation, the second communication port 22 can be selectively communicated with the first sub-air duct 25.

[0161] The shape of the air duct switching piece 50 can match the shape of the rotating cavity 261, so that the shape of the air duct switching piece 50 can have a large degree of coincidence with the shape of the rotating cavity 261. In this way, the air duct switching piece 50 is conveniently rotated in the rotating cavity 261, and when the air duct switching piece 50 is rotated to the closed position, the two ends of the communication passage can be blocked by the cavity wall of the rotating cavity 261.

[0162] Referring to Figure 12The connecting channel 51 has an inlet end 511 and an outlet end 512. In some embodiments, the diameter of the connecting channel 51 can gradually increase along the direction from the inlet end 511 to the outlet end 512. For example, the connecting channel 51 can be a funnel-shaped channel. When the air duct switching component 50 is in the open position, the inlet end 511 is connected to the first sub-air duct 25, and the outlet end 512 is connected to the second connecting port 22, so that most of the airflow in the air duct component 20 can enter the connecting channel 51 through the inlet end 511 and be blown towards the cleaning component through the second connecting port 22, thereby improving the self-cleaning and drying efficiency of the cleaning component. At the same time, in the dust collection mode, the diversion effect of the second connecting port 22 can be further enhanced, reducing the airflow rate and the force generated by the airflow blowing towards the filter element 412 and the dust box 410.

[0163] See Figure 11 The air duct assembly also includes a control element 60, which is connected to the air duct switching element 50. The control element 60 is configured to control the rotation of the air duct switching element 50 so that the air duct switching element 50 rotates in different directions under the control of the control element 60, thereby realizing the switching between the open position and the closed position.

[0164] For example, the control element 60 can be a motor. By rotating the motor in both directions, the air duct switching element 50 can be controlled to rotate in different directions, thereby switching between the open and closed positions.

[0165] Figure 13 This is a schematic diagram of the structure of a duct cover 27, a first windbreak 70, and a second windbreak 200 provided in an embodiment of this application.

[0166] See 9 and Figure 13 In some embodiments, the air duct assembly further includes a first windbreak 70, which is located within the first sub-air duct 25 opposite to the third connecting port 23. Furthermore, the first windbreak 70 is rotatably connected to the air duct wall of the first sub-air duct 25 to open or close the third connecting port 23 during rotation. Specifically, the first windbreak 70 can be rotatably connected to the inner wall of the air duct cover 27.

[0167] The first baffle 70 is rotatably connected to the duct wall of the first sub-duct 25, so that the connection between the duct component 20 and the dust collecting fan 12 can be controlled by opening or closing the third connecting port 23 through the rotation of the first baffle 70. Thus, when the duct component 20 is connected to the dust collecting fan 12, in dust collection mode, the airflow generated by the dust collecting fan 12 can achieve self-cleaning of the dust box 410 and the cleaning components, as well as self-cleaning and drying. When the cleaning base station 100 is in other operating modes (such as the drying mode mentioned below), the duct component 20 can be disconnected from the dust collecting fan 12 to avoid affecting the normal operation of the cleaning base station 100 in other operating modes.

[0168] Specifically, when the first wind blocker 70 opens the third communication port 23, the air duct 20 is in communication with the dust collection fan 12, and when the first wind blocker 70 closes the third communication port 23, the air duct 20 is not in communication with the dust collection fan 12.

[0169] Referring to FIGS. 9 and Figure 13 In the dust collection mode, the first wind blocker 70 is configured to rotate into the first sub-air duct 25 under the push of the air flow output from the third communication port 23 to open the third communication port 23. Specifically, in the dust collection mode, when the air flow generated by the dust collection fan 12 passes through the third communication port 23, the first wind blocker 70 is pushed to rotate into the first sub-air duct 25 to open the third communication port 23. In this way, while achieving the communication between the air duct 20 and the dust collection fan 12, compared with the way of setting an additional driving device in the air duct 20 to drive the first wind blocker 70 to rotate, the structure of the air duct assembly can be simplified, and the cost of the cleaning system can be reduced.

[0170] Referring to FIGS. 9 and Figure 13 The air duct assembly can further include a torsion spring 80 and a rotating shaft 90, and the rotating shaft 90 is rotatably arranged on the air duct wall of the first sub-air duct 25 at a position opposite to the third communication port 23. Specifically, the rotating shaft 90 can be rotatably arranged on the inner wall of the air duct upper cover 27. The first wind blocker 70 is connected to one side of the rotating shaft 90 adjacent to the third communication port 23. The torsion spring 80 is arranged on the rotating shaft 90, and one end of the torsion spring 80 abuts against the air duct wall of the first sub-air duct 25, and the other end of the torsion spring 80 abuts against the first wind blocker 70. In this way, while achieving the rotatable connection between the first wind blocker 70 and the air duct wall of the first sub-air duct 25, when the air flow is output from the third communication port 23, the air flow pushes the first wind blocker 70 to rotate into the first sub-air duct 25 around the rotating shaft 90 to open the third communication port 23, and at this time, the torsion spring 80 is deformed. When the air flow is not output from the third communication port 23, the torsion spring 80 generates a rebound force to drive the first wind blocker 70 to rotate around the rotating shaft 90 to the side of the third communication port 23 to close the third communication port 23, thereby achieving the automatic reset of the first wind blocker 70.

[0171] The first wind blocker 70 is made of a plate-shaped structure of a hard material. For example, the hard material can include a material such as polypropylene that is not easy to deform. Compared with a soft material, by limiting the hard material of the first wind blocker 70, the first wind blocker 70 can be better automatically reset when the air flow is not output from the third communication port 23.

[0172] Figure 14 FIG. 10 shows a sectional view of the air duct assembly in the C-C direction. Figure 8 FIG. 11 shows a sectional view of the air duct assembly in the D-D direction.

[0173] Referring to FIGS. 9 and Figure 14In some embodiments, the duct assembly may further include a second baffle 200, which is rotatably disposed within the duct component 20 and located between the first connecting port 21 and the fourth connecting port 24 of the duct component 20 (described below). Specifically, the second baffle 200 is located within the first sub-duct 25 adjacent to the first connecting port 21, and the second baffle 200 is rotatably connected to the duct wall of the first sub-duct 25 to open or close the first connecting port 21 during rotation. Specifically, one side of the second baffle 200 may engage with the inner wall of the duct cover 27, while the other side of the second baffle 200 may not be connected to other duct walls of the duct component 20, so that when the second baffle 200 is connected to the duct wall of the first sub-duct 25, it can rotate relative to the duct wall of the first sub-duct 25 (i.e., the second baffle 200 is rotatably connected to the duct wall of the first sub-duct 25).

[0174] The second baffle 200 is rotatably connected to the duct wall of the first sub-duct 25, so that the connection between the dust box 410 and components such as the dust collecting fan 12 can be controlled by opening or closing the first connecting port 21 through the rotation of the second baffle 200. In this way, when the dust box 410 is connected to the dust collecting fan 12 through the duct 20, the airflow generated by the dust collecting fan 12 can achieve self-cleaning of the dust box 410 in dust collection mode.

[0175] Specifically, when the first windbreak 70 opens the third connecting port 23, the air duct 20 is connected to the dust collection fan 12.

[0176] In some embodiments, the second wind deflector 200 is a flexible wind deflector plate, which is configured to deform and rotate under the impetus of airflow within the first sub-duct 25 to open or close the first connection port 21.

[0177] In this way, while achieving the connection between the air duct component 20 and the dust collection fan 12, compared to setting an additional drive device in the air duct component 20 to drive the second baffle component 200 to rotate, the structure of the air duct component can be simplified, and the cost of the cleaning system can be reduced.

[0178] Furthermore, since the first connecting port 21 is located at one end of the air duct component 20, while the second connecting port 22 and the third connecting port 23 are located at the other end of the air duct component 20, and the second baffle 200 is located in the first sub-air duct 25 on the side adjacent to the first connecting port 21, in the dust collection mode, when the airflow generated by the dust collection fan 12 enters the air duct component 20 through the third connecting port 23 and flows toward the side of the first connecting port 21, it will push the second baffle 200 to deform and rotate, so as to open the first connecting port 21 and allow the airflow to enter the dust box 410.

[0179] When in the dust collection mode, and the second communication port 22 causes the gas to be shunted to the dust collection fan 12, the gas flow to the first communication port 21 is reduced, at this time, the thrust of the gas flow to the second air baffle 200 is reduced, so that the second air baffle 200 is partially reset, the opening degree of the first communication port 21 is reduced, and the gas flow to the first communication port 21 can be further blocked, thereby further reducing the gas flow to the filter 412 and the box body 411 of the dust box 410, and the force (such as the wind force) generated by the gas flow.

[0180] The above is the first cleaning base station provided by the embodiment of the application, that is, the cleaning base station 100 in which the air duct 20 is connected with the dust box 410, the cleaning element and the dust collection fan 12.

[0181] The embodiment of the application also provides a second cleaning base station.

[0182] The same as the first cleaning base station, the second cleaning base station also has the air duct 20 and the first air baffle 70 and the second air baffle 200, and the air duct 20 also has the first communication port 21 and the second communication port 22, so that the air duct 20 is connected with the dust box 410 through the first communication port 21 and is connected with the cleaning element through the second communication port 22.

[0183] The difference between the second cleaning base station and the first cleaning base station is that the air duct 20 is also connected with the hot air assembly 300 in the second cleaning base station. The structure of the air duct 20 and the arrangement of the first air baffle 70 and the second air baffle 200 in the air duct 20 can be referred to the related description in the above, and will not be described here.

[0184] The difference between the second cleaning base station and the first cleaning base station will be further described below mainly in combination with the drawings.

[0185] Referring to Figure 3 and Figure 7 In some embodiments, the cleaning base station 100 can also include the hot air assembly 300, and the air duct 20 also has a fourth communication port 24, and the hot air assembly 300 is arranged at the fourth communication port 24.

[0186] The cleaning base station 100 has a drying mode, and in the drying mode:

[0187] The hot air assembly 300 is configured to output hot gas flow to the fourth communication port 24, and the first communication port 21 is connected with the fourth communication port 24.

[0188] In the drying mode, the hot air assembly 300 can communicate with the dust box 410 through the air duct 20 by the communication between the first communication port 21 and the fourth communication port 24. In this way, the hot air flow generated by the hot air assembly 300 can enter the dust box 410 through the first communication port 21 after passing through the fourth communication port 24, so as to dry the dust box 410 and the components (such as the filter 412) in the dust box 410.

[0189] It should be noted that when the hot air flow generated by the hot air assembly 300 flows to the air duct 20 through the fourth communication port 24, the hot air flow can push the second air baffle 200 to rotate, so that the fourth communication port 24 communicates with the first communication port 21.

[0190] In addition, in the drying mode:

[0191] The second communication port 22 also selectively communicates with the fourth communication port 24. That is, in the drying mode, when the dust box 410 is dried, the cleaning base 100 can selectively communicate the second communication port 22 with the fourth communication port 24, or can also selectively not communicate the second communication port 22 with the fourth communication port 24. When the second communication port 22 communicates with the fourth communication port 24, the hot air assembly 300 can communicate with the cleaning component through the air duct 20.

[0192] By selectively communicating the second communication port 22 with the fourth communication port 24, the cleaning base 100 can selectively communicate the second communication port 22 with the fourth communication port 24 when the dust box 410 and the components in the dust box 410 are dried in the drying mode, so that the hot air assembly 300 can communicate with the cleaning component through the air duct 20. In this way, at least part of the garbage remaining on the cleaning component can be blown away when the hot air flow generated by the hot air assembly 300 passes through the cleaning component, so as to clean and dry the cleaning component.

[0193] In this way, when the dust box 410 is dried in the drying mode, the cleaning base 100 can selectively clean and dry the cleaning component, so as to enhance the flexibility of the cleaning base 100 in the drying mode, and can also adjust the drying efficiency and effect of the dust box 410 and the cleaning component by controlling the communication time of the second communication port 22 and the fourth communication port 24, thereby improving the user experience.

[0194] At the same time, the cleaning base 100 only needs one hot air assembly 300 to dry the dust box 410 and the cleaning component, so as to reduce the number of hot air assemblies 300 compared with the existing cleaning system.

[0195] In the drying mode, when the second communication port 22 does not communicate with the fourth communication port 24, the air duct 20 can be used as the air outlet duct of the hot air assembly 300 and the drying channel of the dust box 410.

[0196] In drying mode, when the second connecting port 22 is connected to the fourth connecting port 24, the air duct component 20 can be used not only as the air outlet duct of the hot air assembly 300 and the drying channel of the dust box 410, but also as the self-cleaning and drying channel of the cleaning component, making the function of the air duct component 20 more diversified.

[0197] Compared to the existing clean base station 100, the embodiments of this application can reduce the number of channels inside the clean base station 100 by setting up a multi-functional air duct structure, such as the air duct component 20.

[0198] See Figure 3 This application also provides a third type of cleaning base station, which is a combination of the first and second types of cleaning base stations, and includes all the features described above for the first and second types of cleaning base stations. That is, in the third type of cleaning base station, the air duct component 20 is connected to the dust collection fan 12 through the third connection port 23, and simultaneously connected to the hot air assembly 300 through the fourth connection port 24. In other words, the air duct component 20 is simultaneously connected to both the dust collection fan 12 and the hot air assembly 300. At this time, the cleaning base station 100 can independently choose to perform self-cleaning or drying treatment on either the dust box 410 or the cleaning component, while also allowing the cleaning base station 100 to share a single air duct component 20 in both dust collection and drying modes. This saves space occupied by the air duct component 20 in the cleaning base station 100 and facilitates the miniaturization of the cleaning base station 100.

[0199] The structure of the third type of clean base station will be further explained below with reference to the accompanying drawings.

[0200] For the third type of cleaning base station, in the drying mode, except that the first connection port 21 is connected to the fourth connection port 24 and the second connection port 22 is selectively connected to the fourth connection port 24, the second connection port 22 is not connected to the third connection port 23, so as to avoid the hot air generated by the hot air assembly 300 flowing to the dust collection fan 12 through the third connection port 23 and causing the loss of hot air, thereby ensuring the drying effect of the cleaning base station 100 on the dust box 410 and the self-cleaning and drying effect on the cleaning components in the drying mode.

[0201] See Figure 1 and Figure 3The hot air assembly 300 comprises a drying fan 310 and a heating member 320. The drying fan 310 is located outside the air duct member 20 and is configured to make the outside airflow of the air duct member 20 enter the fourth communication port 24. The heating member 320 is located at the air outlet side of the drying fan 310 and is configured to heat the outside airflow to form a hot airflow. In this way, the hot air assembly 300 can convert the outside airflow of the air duct member 20 into a hot airflow and output the hot airflow to the fourth communication port 24, so as to realize the drying treatment of the dust box 410 and the self-cleaning and drying treatment of the cleaning member at the same time.

[0202] Referring to Figure 11 and Figure 12 The air duct switching member 50 is movably arranged in the air duct member 20 and located between the second communication port 22 and the fourth communication port 24. For example, the air duct switching member 50 is movably arranged in the second sub-air duct 26. The air duct switching member 50 is configured to selectively communicate the second communication port 22 with the fourth communication port 24 when moving in the air duct member 20.

[0203] In this way, by moving the air duct switching member 50 in the air duct member 20, the communication state of the second communication port 22 and the fourth communication port 24 can be controlled. When the self-cleaning and drying treatment of the cleaning member is needed in the drying mode, the second communication port 22 and the fourth communication port 24 can be communicated by moving the air duct switching member 50, so that the hot airflow flows to the cleaning member.

[0204] In addition, since the air duct switching member 50 is located between the second communication port 22 and the fourth communication port 24, when the air duct switching member 50 moves to communicate the second communication port 22 with the fourth communication port 24, the second communication port 22 is opposite to the fourth communication port 24, so that most of the hot airflow output by the fourth communication port 24 flows to the cleaning member through the second communication port 22, thereby improving the drying effect of the cleaning member.

[0205] When only the dust box 410 needs to be dried in the drying mode, the second communication port 22 can be communicated with the fourth communication port 24 by moving the air duct switching member 50, so that the hot airflow flows to the dust box 410.

[0206] It should be noted that, considering that the time for drying the cleaning member is relatively long, when the cleaning member is dried in the drying mode (i.e., the second communication port 22 is communicated with the fourth communication port 24), the fourth communication port 24 is communicated with the first communication port 21, so that a small amount of hot airflow is used to dry the dust box 410 when the cleaning member is dried. Based on the actual situation, whether the dust box 410 is dried first or the cleaning member is dried first is not limited.

[0207] The moving mode of the air duct switching piece 50 in the second sub-air duct 26 includes the rotation mentioned above. When the air duct switching piece 50 rotates to the open position, the second communication port 22 is communicated with the fourth communication port 24. Correspondingly, when the air duct switching piece 50 rotates to the closed position, the second communication port 22 is not communicated with the fourth communication port 24.

[0208] Referring to Figure 7 and Figure 8 The fourth communication port 24 and the second communication port 22 are located on opposite sides of the air duct piece 20, and the projection of the fourth communication port 24 on the opposite side of the air duct piece 20 has an overlapping area with the second communication port 22. That is, the projection of the fourth communication port 24 on the side of the air duct piece 20 on which the second communication port 22 is arranged has an overlapping area with the second communication port 22. In this way, when the cleaning base station 100 arranges the air duct switching piece 50 between the second communication port 22 and the fourth communication port 24 of the air duct piece 20, the second communication port 22 can be selectively communicated with the fourth communication port 24.

[0209] Since the fourth communication port 24 and the second communication port 22 are located on opposite sides of the air duct piece 20, the fourth communication port 24 is also located on the air duct wall of the second sub-air duct 26 opposite the second communication port 22. The fourth communication port 24 is formed in a similar manner to the second communication port 22, and the relevant description of the second communication port 22 is described above and will not be repeated here.
