Description

Technical Field

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

[0002] A cleaning device is a type of smart home appliance that can automatically clean the surface to be cleaned while walking. For example, the cleaning device can be a sweeping robot. The cleaning device has a cleaning part and a dust box. During the walking process, 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 completes the cleaning task, it returns to the cleaning base station, where the cleaning parts of the cleaning device are self-cleaned and dried. The cleaning parts include a dust box and cleaning parts. However, in order to realize the self-cleaning and drying of the dust box of the cleaning device and the drying of the cleaning parts in the current cleaning base station, multiple separate channels are provided in the existing cleaning base station, resulting in a large number of channels in the cleaning base station. Summary of the invention

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

[0005] In a first aspect, an embodiment of the present application provides a cleaning base station, including:

[0006] The base station includes a dust collection container and a dust collection fan, wherein the dust collection container is configured to be connected to one side of a dust box in the cleaning device, and the dust collection fan has a suction port and an air outlet, and the suction port is connected to the dust collection container;

[0007] The air duct assembly comprises an air duct member, the air duct member has a first communication port, a second communication port and a third communication port, the air outlet is connected to the third communication port, the first communication port is configured to be connected to the other side of the dust box; the second communication port is connected to the cleaning member in the cleaning device;

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

[0009] The dust collecting fan is constructed to vacuum the dust collecting container through the suction port and output airflow to the third connecting port through the air outlet. The third connecting port is connected with the first connecting port so that the airflow output from the third connecting port is blown into the dust box through the first connecting port; the second connecting port is constructed to be able to selectively connect with the third connecting port so that the airflow output from the third connecting port is blown toward the cleaning part through the second connecting port.

[0010] In the dust collection mode of the embodiment of the present application, the dust collection fan vacuums the dust collection container, making the dust collection container in a negative pressure state. The garbage in the dust box can be sucked and temporarily stored in the dust collection container to achieve self-cleaning of the dust box, thereby reducing the number of times the user cleans the dust box and improving the user experience.

[0011] Furthermore, the second connecting port is constructed to be selectively connected to the third connecting port, so that in the dust collection mode, the cleaning base station can perform self-cleaning on the dust box while selectively connecting the second connecting port to the third connecting port, so that the dust collection fan can be connected to the cleaning part through the air duct part, so that the airflow generated by the dust collection fan can also blow away at least part of the garbage remaining on the cleaning part when passing through the cleaning part, so as to perform self-cleaning and drying on the cleaning part, 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 connecting port is connected to the third connecting port, the duct member can be used as a self-cleaning and drying channel of the cleaning member in addition to being used as the air outlet duct of the dust collecting fan and the self-cleaning channel of the dust box, thereby making the function of the duct member more diversified and reducing the number of channels in the cleaning base station.

[0013] In some embodiments, the first connecting port is configured to communicate with the cavity at the top of the dust box, and the cavity is surrounded by the dust box body and the filter element located in the box body. In this way, in the dust collection mode, the airflow generated by the dust collection fan can be blown from the top of the dust box to the filter element through the first connecting port, so that the garbage remaining on the filter element can be blown into the dust box, and when the dust collection fan vacuums the dust collection container, the garbage blown from the filter element into the dust box can be sucked and temporarily stored in the dust collection container, so as to reduce the number of times the user cleans the filter element, thereby improving user experience.

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

[0015] The connection state between the second connecting port and the third connecting port is constructed to change periodically, and the connection state between the second connecting port and the third connecting port includes a first time period and a second time period within one change cycle; during the first time period, the second connecting port is not connected with the third connecting port; during the second time period, the second connecting port is connected with the third connecting port.

[0016] In this way, in the first time period, the airflow generated by the dust collecting fan can only be blown to the filter element and the dust box body through the first connecting port, so that the garbage remaining on the filter element can be blown into the dust box and then sucked and temporarily stored in the dust collecting container. In the second time period, part of the airflow generated by the dust collecting fan will be blown to the filter element and the dust box body through the first connecting port, and the rest of the airflow generated by the dust collecting fan will be diverted by the second connecting port, so that the diverted part of the airflow will be blown to the cleaning element, so as to perform a self-cleaning process on the cleaning element and dry the cleaning element at the same time, thereby avoiding the waste of the airflow generated by the dust collecting fan in the second time period.

[0017] Moreover, during the second time period, the air flow rate blowing toward the filter element and the dust box and the force generated by the air flow (such as the wind force) can be reduced to avoid the air flow generated by the dust collecting fan from continuously and massively blowing toward the filter element, thereby ensuring that the garbage in the dust box can be smoothly sucked into the dust collecting container, thereby achieving self-cleaning of the dust box.

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

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

[0020] In some embodiments, the cleaning base station further includes a hot air component, the air duct member further includes a fourth connecting port, and the hot air component is disposed at the fourth connecting port; the cleaning base station has a drying mode, and in the drying mode:

[0021] The hot air component is configured to output a hot air flow to the fourth connecting port, the first connecting port is connected to the fourth connecting port, the second connecting port is selectively connected to the fourth connecting port, and the second connecting port is not connected to the third connecting port.

[0022] In this way, the air duct component is connected to the dust collecting fan and the hot air component at the same time. At this time, the cleaning base station can independently choose to perform self-cleaning or drying processing on either the dust box or the cleaning component, and the cleaning base station can also share one air duct component in the dust collection mode and the drying mode, which can save the space occupied by the air duct component in the cleaning base station and is conducive to the miniaturization of the cleaning base station.

[0023] Furthermore, since the second connecting port is not connected to the third connecting port in the drying mode, this can prevent the hot air generated by the hot air component from flowing to the dust collecting fan through the third connecting port and causing hot air loss, thereby ensuring the drying effect of the cleaning base station on the dust box and the self-cleaning and drying effect of the cleaning element in the drying mode.

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

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

[0026] In this way, the hot air component can convert the external airflow of the air duct member into hot airflow, and output the hot airflow to the fourth connecting port, thereby achieving the self-cleaning and drying of the cleaning member while drying the dust box.

[0027] In some embodiments, the fourth communication port and the second communication port are located on opposite sides of the air duct member, and a projection of the fourth communication port on the opposite side of the air duct member has an overlapping area with the second communication port.

[0028] In this way, when the cleaning base station is provided with an air duct switching member between the second connecting port and the fourth connecting port of the air duct member, it is possible to facilitate the selective connecting of the second connecting port with the fourth connecting port.

[0029] In some embodiments, the air duct member includes a first sub-air duct and a second sub-air duct that are connected to each other, and the air duct wall of the first sub-air duct has a first communication port and a third communication port;

[0030] The second sub-air duct has a second connecting port on its air duct wall, and the second connecting port is configured to be selectively connected to the first sub-air duct, so that in the dust collection mode, the second connecting port can be connected to the third connecting port through the first sub-air duct.

[0031] In some embodiments, the air duct assembly further includes an air duct switching member, and the air duct switching member is movably disposed in the second sub-air duct;

[0032] The duct switching member is constructed to selectively connect the second connecting port with the first sub-duct when moving in the duct member, so that when the duct switching member connects the second connecting port with the first sub-duct, the second connecting port can be connected with the third connecting port through the first sub-duct.

[0033] In some embodiments, a rotating cavity is provided in the second sub-air duct, and the air duct switching member is rotatably disposed in the rotating cavity;

[0034] The air duct switching member is configured to selectively connect the second connecting port with the first sub-air duct when the air duct switching member rotates in the second sub-air duct. Thus, when the air duct switching member is movably disposed in the second sub-air duct, the second connecting port can be selectively connected with the first sub-air duct by the rotation of the air duct switching member in the rotating chamber.

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

[0036] When the air duct switching member is in the open position, the communication channel is connected to the second communication port and the first sub-air duct, so that the second communication port is connected to the first sub-air duct;

[0037] When the air duct switching member 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 connected with the first sub-air duct.

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

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

[0040] When the air duct switching component is in the open position, the inlet end is connected with the first sub-air duct, and the outlet end is connected with the second connecting port, so that most of the airflow in the air duct component can enter the connecting channel through the inlet end, and be blown to the cleaning component through the second connecting port, thereby improving the self-cleaning and drying efficiency of the cleaning component. In the dust collection mode, the diversion effect of the second connecting port can be further enhanced, reducing the airflow rate blown to the filter element and the dust box and the force generated by the airflow.

[0041] In some embodiments, the air duct assembly also includes a control member, which is connected to the air duct switching member and is constructed to control the rotation of the air duct switching member so that the air duct switching member rotates in different directions under the control of the control member, thereby achieving switching between an open position and a closed position.

[0042] In some embodiments, the air duct assembly further includes a first wind shield, which is located in the first sub-duct at a position opposite to the third connecting port, and is rotatably connected to the duct wall of the first sub-duct to open or close the third connecting port when rotating.

[0043] The first wind shield is connected to the duct wall of the first sub-duct through rotation, so that the connection state between the duct member and the dust collecting fan is controlled by opening or closing the third connecting port through the rotation of the first wind shield. In this way, when the duct member is connected to the dust collecting fan, in the dust collection mode, the airflow generated by the dust collecting fan can achieve self-cleaning of the dust box and self-cleaning and drying of the cleaning member. When the cleaning base station is in other working modes (such as drying mode), the duct member may not be connected to the dust collecting 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 shield is configured to rotate toward the first sub-air duct under the impetus of the airflow output from the third communication port to open the third communication port.

[0045] In this way, while achieving the connection between the air duct member and the dust collecting fan, compared with the method of providing an additional driving device in the air duct member to drive the first wind shield member to rotate, it can reduce and simplify the structure of the air duct component and reduce the cost of the cleaning system.

[0046] In some embodiments, the air duct assembly further includes a torsion spring and a rotating shaft, and the rotating shaft is rotatably disposed on the air duct wall of the first sub-air duct at a position opposite to the third connecting port;

[0047] The first wind shield is connected to one side of the rotating shaft adjacent to the third connecting port; the torsion spring is passed through the rotating shaft, and one end of the torsion spring abuts against the air duct wall of the first sub-air duct, and the other end of the torsion spring abuts against the first wind shield.

[0048] In this way, on the basis of realizing the rotational connection between the first wind shield and the wind duct wall of the first sub-wind duct, when the third connecting port outputs airflow, the airflow will push the first wind shield to rotate around the rotation axis toward the first sub-wind duct to open the third connecting port, at which time the torsion spring will deform. When the third connecting port does not output airflow, the torsion spring will generate a rebound force to drive the first wind shield to rotate around the rotation axis toward one side of the third connecting port to close the third connecting port, thereby realizing the automatic reset of the first wind shield.

[0049] In some embodiments, the air duct assembly further includes a second wind shield, which is located on one side of the first sub-duct adjacent to the first connecting port, and is rotatably connected to the duct wall of the first sub-duct to open or close the first connecting port when rotating.

[0050] The second wind shield is connected to the duct wall of the first sub-duct by rotation, so that the connection state between the dust box and the dust collecting fan and other components can be controlled by opening or closing the first connection port through the rotation of the second wind shield. In this way, when the dust box is connected to the dust collecting fan through the duct member, in the dust collecting mode, the airflow generated by the dust collecting fan can realize the self-cleaning process of the dust box.

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

[0052] In this way, while achieving the connection between the air duct member and the dust collecting fan, compared with the method of providing an additional driving device in the air duct member to drive the second wind shield member to rotate, it can reduce and simplify the structure of the air duct component and reduce the cost of the cleaning system.

[0053] In some embodiments, the dust collection base station also includes a dust collection air duct, which is arranged between the dust collection container and the dust box to connect the dust collection container and one side of the dust box, so that the dust collection container can be connected to one side of the dust box through the dust collection air duct.

[0054] In a second aspect, an embodiment of the present application further provides a cleaning base station, including:

[0055] Base station;

[0056] The air duct assembly comprises an air duct member, wherein the air duct member has a first communication port, a second communication port and a fourth communication port, wherein the first communication port is configured to communicate with the dust box; and the second communication port is configured to communicate with the cleaning member in the cleaning device;

[0057] A hot air component, which is arranged at the fourth connecting port;

[0058] The cleaning base station has a drying mode. In drying mode:

[0059] The hot air component is configured to output a hot air flow to the fourth connecting port, the first connecting port is connected to the fourth connecting port, and the second connecting port is selectively connected to the fourth connecting port.

[0060] In the embodiment of the present application, the first connecting port is connected to the fourth connecting port in the drying mode, so that the hot air component can be connected to the dust box through the air duct. In this way, the hot air flow generated by the hot air component can enter the dust box through the first connecting port after passing through the fourth connecting port, so as to dry the dust box and the components (such as the filter) in the dust box.

[0061] Furthermore, by setting the second connecting port to be selectively connected to the fourth connecting port in the drying mode, the cleaning base station can selectively connect the second connecting port to the fourth connecting port while drying the dust box and the components in the dust box in the drying mode, so that the hot air component can be connected to the cleaning component through the air duct component, so that the hot air flow generated by the hot air component can also blow away at least part of the garbage remaining on the cleaning component when passing through the cleaning component, so as to perform self-cleaning and drying treatment on the cleaning component, thereby enhancing the flexibility of the cleaning base station in the drying mode. At the same time, the embodiment of the present application can also adjust the drying efficiency and drying effect of the dust box and the cleaning component by controlling the connection time between the second connecting port and the fourth connecting port, thereby improving the user experience.

[0062] In the drying mode, when the second connecting port is connected to the fourth connecting port, the air duct member can be used as the self-cleaning and drying channel of the cleaning member in addition to being used as the air outlet duct of the hot air assembly and the drying channel of the dust box, making the functions of the air duct member more diversified. Compared with the existing cleaning base station, the embodiment of the present application can reduce the number of channels in the cleaning base station by setting the multifunctional air duct structure of the air duct member.

[0063] In addition, the embodiment of the present application only requires one hot air component to dry the dust box and the cleaning parts, which can reduce the number of hot air components compared to the existing cleaning system.

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

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

[0066] In this way, the hot air component can convert the external airflow of the air duct member into hot airflow, and output the hot airflow to the fourth connecting port, thereby achieving the self-cleaning and drying of the cleaning member while drying the dust box.

[0067] In some embodiments, the air duct assembly further includes an air duct switching member, which is movably disposed in the air duct and located between the second communication port and the fourth communication port;

[0068] The air duct switching member is configured to selectively connect the second communication port with the fourth communication port when moving in the air duct member.

[0069] In this way, the connection state between the second connecting port and the fourth connecting port can be controlled by the movement of the air duct switching component in the air duct component, so that when the cleaning component needs to be self-cleaned and dried in the drying mode, the second connecting port and the fourth connecting port can be connected through the movable air duct switching component to allow the hot air flow to flow to the cleaning component.

[0070] Furthermore, since the air duct switching component is located between the second connecting port and the fourth connecting port, when the air duct switching component moves to connect the second connecting port with the fourth connecting port, the second connecting port is opposite to the fourth connecting port, so that most of the hot air flow 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 the drying mode, if only the dust box needs to be dried, the second connecting port can be disconnected from the fourth connecting port through the movable air duct switching member, so that the hot air flows into the dust box.

[0072] In a third aspect, an embodiment of the present application further provides a cleaning system, comprising a cleaning device and a cleaning base station as described above, wherein the cleaning device has a dust box and a cleaning member, the cleaning base station comprises a dust collection container and an air duct member, the dust collection container is connected to one side of the dust box, and the first communication port of the air duct member is connected to the other side of the dust box;

[0073] The second communication port of the air duct member is communicated with the cleaning member.

[0074] The cleaning system of the present application has the effect of cleaning the base station as described above, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0105] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0106] The embodiment of the present application provides a cleaning system. The cleaning system includes a cleaning device and a cleaning base station. The cleaning device may include a cleaning robot, a floor scrubber, or other cleaning device that can automatically clean a surface to be cleaned. The surface to be cleaned may be the ground, etc.

[0107] Taking the sweeping robot as an example, the structure of the cleaning system is further explained below.

[0108] The cleaning device has a dust box and a cleaning member. When the sweeping robot is walking, it can suck impurities on the surface to be cleaned into the dust box for temporary storage, and the cleaning member can contact and rub the surface to be cleaned to clean the surface. For example, the impurities on the surface to be cleaned may include dust and the like. The cleaning member may include a rag and the like. A filter is also provided in the dust box, and the filter can filter impurities entering the dust box. After the filter filters the impurities, some impurities will remain on the filter, and the impurities passing through the filter will be temporarily stored in the dust box.

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

[0110] Figure 1 and Figure 2 The schematic diagram of the structure of a cleaning system at different viewing angles is shown. Figure 1 and Figure 2 The cleaning device 400 in the cleaning system shown in FIG. 1 is a sweeping robot.

[0111] See also Figure 1 and Figure 2 The cleaning system further includes a cleaning base station 100. After the cleaning device 400 cleans the surface to be cleaned, it can return to the cleaning base station 100, and the cleaning base station 100 can perform self-cleaning and drying processing on the dust box 410 in the cleaning device 400, and dry the cleaning parts in the cleaning device 400.

[0112] However, in order to realize the self-cleaning and drying of the dust box and the drying of the cleaning parts in the current cleaning base station, multiple independent channels are set in the existing cleaning base station. These channels include the dust collection fan outlet channel, the cleaning part self-cleaning channel, the dust box drying channel and the cleaning part drying channel. These channels are separated from each other and have single functions, which will result in a large number of channels in the cleaning base station.

[0113] In view of this, an embodiment of the present application provides a cleaning base station, in which an air duct member is provided. The air duct member is a multifunctional air duct member, having a plurality of connecting ports, so that the air duct member is connected with the dust box and the cleaning member, and the air duct member can also be connected with at least one of the dust collecting fan and the hot air component, so that the functions of the air duct member are more diversified, so as to reduce the number of channels in the cleaning base station.

[0114] When the duct member is connected to the dust collecting fan and the cleaning base station is in the dust collection mode, the duct member can selectively connect the dust collecting fan to the cleaning member while connecting the dust collecting fan to the dust box, so that when the cleaning base station performs self-cleaning on the dust box, it can also autonomously and selectively perform self-cleaning and drying on the cleaning member, so as to enhance the flexibility of the cleaning base working in the dust collection mode. At the same time, the duct member can be used as a self-cleaning channel for the dust box and a self-cleaning and drying channel for the cleaning member.

[0115] When the air duct member is connected to the hot air component and the cleaning base station is in the drying mode, the air duct member can selectively connect the hot air component to the cleaning component while connecting the hot air component to the dust box, so that the cleaning base station can autonomously and selectively dry the cleaning component while drying the dust box, so as to enhance the flexibility of the cleaning base station in the drying mode. At the same time, the air duct member can be used as a drying channel for the dust box and a self-cleaning and drying channel for the cleaning component.

[0116] In addition, when the air duct component is connected to the dust collection fan and the hot air component, the cleaning base station can independently choose to perform self-cleaning or drying processing on either the dust box or the cleaning component. At the same time, the cleaning base station can share one air duct component in the dust collection mode and the drying mode, which can save the space occupied by the air duct component in the cleaning base station and is conducive to the miniaturization of the cleaning base station.

[0117] Figure 3 A partial exploded view of a cleaning system provided in an embodiment of the present application is shown. Figure 4 A simplified view of a cleaning system provided in an embodiment of the present application.

[0118] Combine the following Figures 1 to 4 , the structure of the cleaning base station 100 is further explained.

[0119] See also Figures 1 to 4The cleaning base station 100 includes a base station 10, and the base station 10 includes a dust collection container 11 and a dust collection fan 12. For example, the dust collection container 11 can be a dust bucket, a dust bag, etc. The dust collection container 11 is configured to communicate with one side of the dust box 410 in the cleaning device 400. The dust collection fan 12 has a suction port and an air outlet, and the suction port is communicated with the dust collection container 11, so that the dust collection fan 12 can vacuum the dust collection container 11 through the suction port.

[0120] See also Figure 3 The cleaning base station 100 further includes an air duct assembly, which includes an air duct member 20. The air duct member 20 has a plurality of communication ports. The plurality of communication ports include a first communication port 21, a second communication port 22, and a third communication port 23. The air outlet is connected to the third communication port 23, so that the air duct member 20 is connected to the dust collecting fan 12, so that the generated airflow can be output to the air duct member 20 through the air outlet and the third communication port 23.

[0121] See also 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 is connected to the cleaning member in the cleaning device 400, so that the air duct member 20 is connected to the cleaning member, so that the air duct member 20 can convey air to the cleaning member through the second communication port 22. Specifically, the second communication port 22 can be connected to the cleaning member through a channel in the cleaning device 400, and the channel can be a drying channel in the cleaning device 400.

[0122] The cleaning base station 100 has a dust collection mode. In the dust collection mode:

[0123] The dust collecting fan 12 is constructed to vacuum the dust collecting container 11 through the suction port and output airflow to the third connecting port 23 through the air outlet. The third connecting port 23 is connected to the first connecting port 21 so that the airflow output from the third connecting port 23 is blown into the dust box 410 through the first connecting port 21.

[0124] In this way, when the cleaning base station 100 is in the dust collection mode, the dust collecting fan 12 is connected to the dust box 410 through the air duct member 20, so that the dust collecting container 11, the dust collecting fan 12, the air duct member 20 and the dust box 410 are connected to form a dust collection circuit, and the airflow generated by the dust collecting fan 12 can flow in the airflow circuit. The flow direction can be seen in FIG. Figure 4 The direction indicated by the dotted arrow. Since the dust collecting fan 12 is evacuating the dust collecting container 11, so that the dust collecting container 11 is in a negative pressure state, the garbage in the dust box 410 can be sucked and temporarily stored in the dust collecting container 11, so as to realize the self-cleaning process of the dust box 410, thereby reducing the number of times the user cleans the dust box 410, and improving the user experience.

[0125] And, in dust collection mode:

[0126] The second communication port 22 is configured to be selectively connected to the third communication port 23, so that the airflow output from the third communication port 23 is blown toward the cleaning member through the second communication port 22. That is, in the dust collection mode, the cleaning base station 100 can choose to connect the second communication port 22 with the third communication port 23, or can also choose not to connect the second communication port 22 with the third communication port 23. When the second communication port 22 is connected to the third communication port 23, the dust collection fan 12 can be connected to the cleaning member through the air duct member 20.

[0127] The second connecting port 22 is configured to be selectively connected to the third connecting port 23, so that the cleaning base station 100 can select to connect the second connecting port 22 with the third connecting port 23 while performing self-cleaning on the dust box 410 in the dust collection mode, so that the dust collection fan 12 can be connected to the cleaning member through the air duct member 20, so that the airflow generated by the dust collection fan 12 can also blow away at least part of the garbage remaining on the cleaning member when passing through the cleaning member, so as to perform self-cleaning and drying on the cleaning member. In this way, the flexibility of the cleaning base station 100 in the dust collection mode can be enhanced, and the cleaning member can be selected to be self-cleaned and dried in the dust collection mode, thereby improving the user experience.

[0128] In the dust collection mode, when the second connecting port 22 is not connected to the third connecting port 23, the duct member 20 can be used as the air outlet duct of the dust collecting fan 12 and the self-cleaning channel of the dust box 410. In the dust collection mode, when the second connecting port 22 is connected to the third connecting port 23, the duct member 20 can be used as the self-cleaning and drying channel of the cleaning member in addition to being used as the air outlet duct of the dust collecting fan 12 and the self-cleaning channel of the dust box 410, making the functions of the duct member 20 more diversified. Compared with the existing cleaning base station 100, the embodiment of the present application can reduce the number of channels in the cleaning base station 100 by setting the multifunctional duct structure of the duct member 20.

[0129] See also Figures 1 to 3 In some embodiments, the base station 10 further includes a dust collecting duct 30, which is disposed between the dust collecting container 11 and the dust box 410 to connect the dust collecting container 11 with one side of the dust box 410. In this way, the dust collecting container 11 can be connected to one side of the dust box 410 through the dust collecting duct 30.

[0130] Figure 5 A schematic structural diagram of a dust box 410 and an air duct member 20 is shown.

[0131] See also Figure 5The dust box 410 generally includes a box body 411 and a filter 412 located in the box body 411. The filter 412 may also be called a HEPA, and is used to filter the garbage entering the dust box 410. After passing through the filter 412, some of the garbage will remain on the filter 412. The installation method of the filter 412 in the dust box 410 can be determined according to the structure of the existing sweeping robot, and will not be repeated in this application.

[0132] See also Figure 5 In some embodiments, the first communication port 21 may be configured to communicate with the cavity 413 at the top of the dust box 410, and the cavity 413 is surrounded 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 collecting 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 collecting fan 12 vacuums the dust collecting container 11, the garbage blown from the filter 412 into the dust box 410 can be sucked and temporarily stored in the dust collecting container 11, so as to reduce the number of times the user cleans the filter 412, thereby improving user experience.

[0133] It should be understood that in order to facilitate the connection between the first connecting 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 hole at the top position, so that the first connecting port 21 is connected to the cavity 413 at the top of the dust box 410 through the through hole.

[0134] If the airflow generated by the dust collecting fan 12 continues and blows toward the filter element 412 in large quantities, it will affect the garbage in the dust box 410 from being sucked into the dust collecting container 11.

[0135] Figures 6 to 8 A schematic structural diagram of an air duct assembly at different viewing angles in a first state is shown.

[0136] For this purpose, see Figures 6 to 8 , in some embodiments, in dust collection mode:

[0137] The connection state between the second connecting port 22 and the third connecting port 23 is constructed to change periodically, and the connection state between the second connecting port 22 and the third connecting port 23 includes a first time period and a second time period within one change cycle; during the first time period, the second connecting port 22 is not connected with the third connecting port 23; during the second time period, the second connecting port 22 is connected with the third connecting port 23.

[0138] Since the third connecting port 23 is connected to the first connecting port 21 in the dust collection mode, when the second connecting port 22 is not connected to the third connecting port 23 within the first time period, the airflow generated by the dust collecting fan 12 can only be blown toward the filter element 412 and the dust box 410 through the first connecting port 21, so that the garbage remaining on the filter element 412 can be blown into the dust box 410 and then sucked and temporarily stored in the dust collecting container 11.

[0139] During the second time period, since the second connecting port 22 is connected to the third connecting port 23, at this time, the first connecting port 21 and the second connecting port 22 are both connected to the third connecting port 23, part of the airflow generated by the dust collecting fan 12 will be blown toward the filter element 412 and the box body 411 of the dust box 410 through the first connecting port 21, and the remaining airflow generated by the dust collecting fan 12 will be diverted by the second connecting port 22, so that this diverted part of the airflow will be blown toward the cleaning element.

[0140] In this way, when the connection state between the second connection port 22 and the third connection port 23 changes periodically, and in the second time period, the airflow flow rate blowing toward the filter element 412 and the dust box 410 and the force generated by the airflow (such as the wind force) can be reduced to avoid the airflow generated by the dust collecting fan 12 from continuously and in large quantities blowing toward the filter element 412, so as to ensure that the garbage in the dust box 410 can be smoothly sucked into the dust collecting 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 element 412, and also includes the self-cleaning process of the part of the garbage temporarily stored in the box body 411 after being filtered by the filter element 412.

[0141] In the dust collection mode, the cleaning base station 100 can adjust the self-cleaning efficiency and self-cleaning effect of the dust box 410, the filter element 412 in the dust box 410, and the cleaning element by controlling the time ratio of the second time period in a change cycle.

[0142] For example, the first time period may be smaller than the second time period. For example, taking an operation cycle of 10 seconds as an example, the first time period may be 2 seconds, and the second time period may be 8 seconds. Alternatively, the first time period may be larger than the second time period.

[0143] The present application can flexibly set the change cycle, the first time period and the second time period according to the requirements for the cleanliness of the dust box 410 and the cleanliness of the cleaning parts, etc. In the present application, the sizes of the change cycle, the first time period and the second time period are not further limited.

[0144] In addition, since the diverted part of the airflow will be blown toward the cleaning piece, this part of the airflow will blow away at least part of the residue on the cleaning piece when passing through the cleaning piece, so as to perform self-cleaning treatment on the cleaning piece. At the same time, the flow of the airflow will also accelerate the loss of moisture on the cleaning piece, and can dry the cleaning piece, thereby avoiding the waste of the airflow generated by the dust collection fan 12 in the second time period.

[0145] See also Figure 6 In some embodiments, the first communication port 21 may be located at one end of the air duct member 20, and the second communication port 22 and the third communication port 23 may be located at the other end of the air duct member 20, so that the second communication port 22 is closer to the third communication port 23. In addition, along the direction of the airflow output from the third communication port 23, the second communication port 22 is located downstream of the third communication port 23. In this way, most of the airflow output from the dust collecting fan 12 through the third communication port 23 can be blown to the cleaning member through the second communication port 22, thereby enhancing the diversion effect of the second communication port 22, so as to further reduce the airflow flow rate and the force generated by the airflow blowing to the filter member 412 and the dust box 410 during the second time period, so as to ensure that the garbage in the dust box 410 can be smoothly sucked into the dust collecting container 11. At the same time, the airflow flow rate blowing to the cleaning member can be increased, the airflow generated by the dust collecting fan 12 can be reasonably utilized, and the self-cleaning and drying effects on the cleaning member can be enhanced.

[0146] See also Figure 6 and Figure 7 The air duct member 20 includes a first sub-air duct 25 and a second sub-air duct 26 which 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 port 21 and a third connecting port 23. The air duct wall of the second sub-air duct 26 has a second connecting port 22.

[0147] The second communication port 22 is configured to be selectively communicated with the first sub-air duct 25 , so that in the dust collection mode, the second communication port 22 can be communicated with the third communication port 23 through the first sub-air duct 25 .

[0148] Fig. 9 An exploded view of an air duct assembly provided in an embodiment of the present application.

[0149] See also Fig. 9 The air duct member 20 may include an air duct upper cover 27, an air duct lower cover 28 and an air duct base 29, wherein the air duct upper cover 27 is disposed at the top of the air duct lower cover 28, and the air duct base 29 is disposed at the bottom of the air duct lower cover 28. The air duct upper cover 27 and the air duct base 29 are both connected to the air duct lower cover 28, and the three together form the air duct member 20. The air duct upper cover 27 and part of the air duct lower cover 28 form a first sub-air duct 25, and the air duct base 29 and the remaining air duct lower cover 28 form a second sub-air duct 26.

[0150] See also Fig. 9 As an example, the duct upper cover 27 and the duct lower cover 28 are both provided with a first opening 271, and the two first openings 271 are connected to form a first communication port 21, and the duct lower cover 28 and the duct base 29 are both provided with a second opening 281, and the two second openings 281 are connected to form a second communication port 22. The third communication port 23 is provided on a side of the 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 duct member 20, and along the direction of the third communication port 23 outputting the airflow, the second communication port 22 is located downstream of the third communication port 23.

[0151] See also Fig. 9 In some embodiments, the air duct assembly may further include a plurality of seals 40. For example, the seal 40 may be a sealing ring. The air duct member 20 is provided with seals 40 at least at some of the communication ports, so that when these communication ports are connected to other components in the cleaning system, leakage of airflow at the connection between the communication ports and other components can be avoided. For example, the communication ports provided with the seals 40 may include a first communication port 21, a second communication port 22, and the like.

[0152] Fig.10 Shows Figure 8 Cross-sectional view of the middle air duct component in the AA direction. Fig.11 shows a schematic structural diagram of an air duct assembly in a second state, Fig.12 Shows Fig.11 Cross-sectional view of the middle air duct component in the BB direction.

[0153] See also Fig.10 and Fig.12 , and combined with Fig.11 In some embodiments, the air duct assembly further includes an air duct switching member 50, and the air duct switching member 50 is located in the air duct member 20. The air duct switching member 50 is movably disposed in the air duct member 20. For example, the air duct switching member 50 is movably disposed 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 it moves in the air duct member 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.

[0154] in, Fig.10 This is a structural view showing that the second connecting port 22 is not connected to the first sub-air duct 25. Fig.12 It is a structural view showing that the second connecting port 22 is connected to the first sub-air duct 25 .

[0155] See also Fig.10 and Fig.12The second sub-air duct 26 has a rotating chamber 261, and the air duct switching member 50 is rotatably disposed in the rotating chamber 261. The air duct switching member 50 is configured to selectively connect the second communication port 22 with the first sub-air duct 25 when rotating in the second sub-air duct 26. In this way, while the air duct switching member 50 is movably disposed in the second sub-air duct 26, the second communication port 22 can be selectively connected with the first sub-air duct 25 by rotating the air duct switching member 50 in the rotating chamber 261.

[0156] It should be noted that the air duct switching member 50 may also be disposed in the second sub-air duct 26 in a non-rotational manner such as linear motion, so that the second communication port 22 is selectively connected to the first sub-air duct 25 .

[0157] In the following, the structure of the air duct assembly and the cleaning system is further described by taking the example that the air duct switching member 50 is rotatably disposed in the rotating chamber 261 .

[0158] See also Fig.10 and Fig.12 The air duct switching member 50 has a connecting passage 51 therein, and the air duct switching member 50 has an open position and a closed position when rotating in the rotating chamber 261 .

[0159] See also Fig.10 When the air duct switching member 50 is in the open position, the communication channel 51 communicates with 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 .

[0160] When the air duct switching member 50 is in the closed position, both ends of the communication channel 51 are blocked by the cavity wall of the rotating cavity 261 so that the second communication port 22 is not connected with the first sub-air duct 25 .

[0161] Therefore, when the air duct switching member 50 is switched between the open position and the closed position by rotating, the second communication port 22 can be selectively connected to the first sub-air duct 25 .

[0162] The shape of the air duct switching member 50 can match the shape of the rotating chamber 261, so that the shape of the air duct switching member 50 can have a greater degree of fit with the shape of the rotating chamber 261. In this way, while facilitating the rotation of the air duct switching member 50 in the rotating chamber 261, when the air duct switching member 50 rotates to the closed position, both ends of the passage can be blocked by the cavity wall of the rotating chamber 261.

[0163] See also Fig.12, the connecting channel 51 has an inlet end 511 and an outlet end 512. In some embodiments, the caliber of the connecting channel 51 can be gradually increased in the direction from the inlet end 511 to the outlet end 512. For example, the connecting channel 51 can be a trumpet-shaped channel. When the air duct switching member 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 member 20 can enter the connecting channel 51 through the inlet end 511, and blow to the cleaning member through the second connecting port 22, thereby improving the self-cleaning and drying efficiency of the cleaning member. 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 flow rate and the force generated by the airflow blowing to the filter 412 and the dust box 410.

[0164] See also Fig.11 The air duct assembly also includes a control member 60, which is connected to the air duct switching member 50, and the control member 60 is constructed to control the rotation of the air duct switching member 50 so that the air duct switching member 50 rotates in different directions under the control of the control member 60, thereby realizing switching between the open position and the closed position.

[0165] For example, the control member 60 may be a motor. The air duct switching member 50 may be controlled to rotate in different directions by the forward and reverse rotation of the motor, thereby realizing the switching between the open position and the closed position.

[0166] Fig.13 A schematic structural diagram of an air duct upper cover 27, a first wind shield member 70, and a second wind shield member 200 provided in an embodiment of the present application.

[0167] See 9 and Fig.13 In some embodiments, the air duct assembly further includes a first air shield 70, which is located in the first sub-air duct 25 at a position opposite to the third communication port 23. In addition, the first air shield 70 is rotatably connected to the air duct wall of the first sub-air duct 25 to open or close the third communication port 23 when rotating. Specifically, the first air shield 70 can be rotatably connected to the inner wall of the air duct upper cover 27.

[0168] The first wind shield 70 is connected to the duct wall of the first sub-duct 25 by rotation, so that the connection state between the duct member 20 and the dust collecting fan 12 is controlled by opening or closing the third connecting port 23 by the rotation of the first wind shield 70. In this way, when the duct member 20 is connected to the dust collecting fan 12, in the dust collecting mode, the airflow generated by the dust collecting fan 12 can realize the self-cleaning of the dust box 410 and the self-cleaning and drying of the cleaning member. When the cleaning base station 100 is in other working modes (such as the drying mode mentioned below), the duct member 20 may not be connected to the dust collecting fan 12 to avoid affecting the normal operation of the cleaning base station 100 in other working modes.

[0169] Specifically, when the first wind shielding member 70 opens the third connecting port 23 , the air duct member 20 is connected to the dust collecting fan 12 , and when the first wind shielding member 70 closes the third connecting port 23 , the air duct member 20 is not connected to the dust collecting fan 12 .

[0170] See 9 and Fig.13 In the dust collection mode, the first wind shield 70 is configured to rotate toward the first sub-air duct 25 under the push of the airflow output from the third communication port 23 to open the third communication port 23. Specifically, in the dust collection mode, when the airflow generated by the dust collecting fan 12 passes through the third communication port 23, it will push the first wind shield 70 to rotate toward the first sub-air duct 25 to open the third communication port 23. In this way, while achieving the connection between the air duct member 20 and the dust collecting fan 12, compared with the method of providing an additional driving device in the air duct member 20 to drive the first wind shield 70 to rotate, the structure of the air duct component can be simplified and the cost of the cleaning system can be reduced.

[0171] See 9 and Fig.13 The air duct assembly may further include a torsion spring 80 and a rotating shaft 90, wherein the rotating shaft 90 is rotatably disposed on the air duct wall of the first sub-air duct 25 at a position opposite to the third connecting port 23. Specifically, the rotating shaft 90 may be rotatably disposed on the inner wall of the air duct upper cover 27. The first wind shield 70 is connected to a side of the rotating shaft 90 adjacent to the third connecting port 23. The torsion spring 80 is passed through 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 shield 70. In this way, on the basis of realizing the rotational connection between the first wind shield 70 and the air duct wall of the first sub-air duct 25, when the third connecting port 23 outputs airflow, the airflow will push the first wind shield 70 to rotate around the rotating shaft 90 toward the inside of the first sub-air duct 25 to open the third connecting port 23, and at this time, the torsion spring 80 is deformed. When the third connecting port 23 does not output airflow, a rebound force is generated in the torsion spring 80 to drive the first wind shield 70 to rotate around the rotating shaft 90 toward one side of the third connecting port 23 to close the third connecting port 23 and realize automatic reset of the first wind shield 70 .

[0172] The first windshield 70 is a plate-shaped structure made of a hard material. For example, the hard material may include a material that is not easily deformed, such as polypropylene. Compared with soft materials, the hard material of the first windshield 70 can facilitate the first windshield 70 to automatically reset better when the third connecting port 23 does not output airflow.

[0173] Fig.14 Shows Figure 8 Cross-sectional view of the central air duct component in the CC direction.

[0174] See also Fig.14In some embodiments, the air duct assembly may further include a second air shield 200, which is rotatably disposed in the air duct member 20 and is located between the first connecting port 21 and the fourth connecting port 24 (described below) of the air duct member 20. Specifically, the second air shield 200 is located on a side of the first sub-air duct 25 adjacent to the first connecting port 21, and the second air shield 200 is rotatably connected to the air duct wall of the first sub-air duct 25 to open or close the first connecting port 21 during rotation. Specifically, one side of the second air shield 200 may be engaged with the inner wall of the air duct upper cover 27, while the other side of the second air shield 200 may not be connected to other air duct walls of the air duct member 20, so that when the second air shield 200 is connected to the air duct wall of the first sub-air duct 25, it can rotate relative to the air duct wall of the first sub-air duct 25 (i.e., the second air shield 200 is rotatably connected to the air duct wall of the first sub-air duct 25).

[0175] The second wind shield 200 is connected to the duct wall of the first sub-duct 25 by rotation, so that the connection state between the dust box 410 and the dust collecting fan 12 and other components can be controlled by opening or closing the first connecting port 21 by the rotation of the second wind shield 200. In this way, when the dust box 410 is connected to the dust collecting fan 12 through the duct member 20, in the dust collection mode, the airflow generated by the dust collecting fan 12 can realize the self-cleaning process of the dust box 410.

[0176] Specifically, when the first wind shielding member 70 opens the third connecting port 23 , the air duct member 20 is connected to the dust collecting fan 12 .

[0177] In some embodiments, the second wind shield 200 is a flexible wind shield, and the second wind shield 200 is configured to be deformed and rotated under the push of the airflow in the first sub-air duct 25 to open or close the first communication port 21 .

[0178] In this way, while achieving the connection between the air duct member 20 and the dust collecting fan 12, compared with the method of providing an additional driving device in the air duct member 20 to drive the second wind shield member 200 to rotate, it can reduce and simplify the structure of the air duct component and reduce the cost of the cleaning system.

[0179] Furthermore, since the first connecting port 21 is located at one end of the air duct member 20, and the second connecting port 22 and the third connecting port 23 are located at the other end of the air duct member 20, and the second wind shield member 200 is located on the side of the first sub-air duct 25 adjacent to the first connecting port 21, therefore, in the dust collection mode, when the airflow generated by the dust collecting fan 12 enters the air duct member 20 through the third connecting port 23 and flows toward the side of the first connecting port 21, it will push the second wind shield member 200 to deform and rotate to open the first connecting port 21, so that the airflow enters the dust box 410.

[0180] When in the dust collection mode and the second connecting port 22 generates a gas diversion to the dust collection fan 12, the air flow to the first connecting port 21 is reduced. At this time, the thrust of the airflow on the second wind shield 200 is reduced, so that the second wind shield 200 is partially reset, and the opening degree of the first connecting port 21 is reduced, which can further block the airflow from flowing to the first connecting port 21, thereby further reducing the airflow flow to the filter element 412 and the box body 411 of the dust box 410 and the force generated by the airflow (such as the wind force).

[0181] The above is the first type of cleaning base station provided in the embodiment of the present application, that is, the cleaning base station 100 in which the air duct member 20 is connected to the dust box 410, the cleaning member and the dust collecting fan 12.

[0182] The embodiment of the present application also provides a second cleaning base station.

[0183] The same as the first cleaning base station is that the second cleaning base station is also provided with an air duct member 20 and a first wind shield member 70 and a second wind shield member 200, and the air duct member 20 is also provided with a first connecting port 21 and a second connecting port 22, so that the air duct member 20 is connected with the dust box 410 through the first connecting port 21, and connected with the cleaning member through the second connecting port 22.

[0184] The difference from the first cleaning base station is that in the second cleaning base station, the air duct member 20 is also connected to the hot air assembly 300. The structure of the air duct member 20 and the arrangement of the first wind shield member 70 and the second wind shield member 200 in the air duct member 20 can refer to the relevant description above, which will not be repeated here.

[0185] The following mainly describes the differences between the second cleaning base station and the first cleaning base station in conjunction with the accompanying drawings.

[0186] See also Figure 3 and Figure 7 In some embodiments, the cleaning base station 100 may further include a hot air component 300 , the air duct member 20 may further have a fourth connecting port 24 , and the hot air component 300 may be disposed at the fourth connecting port 24 .

[0187] The cleaning base station 100 has a drying mode. In the drying mode:

[0188] The hot air assembly 300 is configured to output hot air flow to the fourth communication port 24 , and the first communication port 21 is in communication with the fourth communication port 24 .

[0189] In the drying mode, the first connecting port 21 is connected to the fourth connecting port 24, so that the hot air assembly 300 can be connected to the dust box 410 through the air duct member 20. In this way, the hot air flow generated by the hot air assembly 300 can enter the dust box 410 through the first connecting port 21 after passing through the fourth connecting port 24, so as to dry the dust box 410 and the components (such as the filter 412) in the dust box 410.

[0190] It should be noted that when the hot air flow generated by the hot air assembly 300 flows into the air duct member 20 through the fourth connecting port 24 , the hot air flow will push the second wind shielding member 200 to rotate, so that the fourth connecting port 24 is connected to the first connecting port 21 .

[0191] And, in drying mode:

[0192] The second communication port 22 is also selectively connected to the fourth communication port 24. That is, in the drying mode, while drying the dust box 410, the cleaning base station 100 can choose to connect the second communication port 22 with the fourth communication port 24, or can also choose not to connect the second communication port 22 with the fourth communication port 24. When the second communication port 22 is connected to the fourth communication port 24, the hot air component 300 can be connected to the cleaning component through the air duct member 20.

[0193] By selectively connecting the second connecting port 22 with the fourth connecting port 24, the cleaning base station 100 can selectively connect the second connecting port 22 with the fourth connecting port 24 while drying the dust box 410 and the components in the dust box 410 in the drying mode, so that the hot air component 300 can be connected with the cleaning component through the air duct component 20, so that the hot air flow generated by the hot air component 300 can also blow away at least part of the garbage remaining on the cleaning component when passing through the cleaning component, so as to perform self-cleaning and drying treatment on the cleaning component.

[0194] In this way, when the cleaning base station 100 dries the dust box 410 in the drying mode, it can choose to self-clean and dry the cleaning parts, thereby enhancing the flexibility of the cleaning base station 100 in the drying mode. At the same time, the drying efficiency and drying effect of the dust box 410 and the cleaning parts can be adjusted by controlling the connection time between the second connecting port 22 and the fourth connecting port 24, thereby improving the user experience.

[0195] At the same time, the embodiment of the present application only requires one hot air component 300 to dry the dust box 410 and the cleaning parts, which can reduce the number of hot air components 300 compared to the existing cleaning system.

[0196] In the drying mode, when the second connecting port 22 is not connected to the fourth connecting port 24 , the air duct member 20 can be used as an air outlet duct of the hot air assembly 300 and a drying channel of the dust box 410 .

[0197] In the drying mode, when the second connecting port 22 is connected to the fourth connecting port 24, the duct member 20 can be used as a self-cleaning and drying channel of the cleaning member in addition to being used as the air outlet duct of the hot air assembly 300 and the drying channel of the dust box 410, thereby making the functions of the duct member 20 more diversified.

[0198] Compared with the existing cleaning base station 100 , the embodiment of the present application can reduce the number of channels in the cleaning base station 100 by disposing the multifunctional air duct structure of the air duct member 20 .

[0199] See also Figure 3 , the embodiment of the present application also provides a third cleaning base station, which is a combination of the first cleaning base station and the second cleaning base station, and includes all the features described above for the first cleaning base station and the second cleaning base station. That is to say, while the air duct member 20 in the third cleaning base station is connected to the dust collecting fan 12 through the third connecting port 23, the air duct member 20 is also connected to the hot air assembly 300 through the fourth connecting port 24, that is, the air duct member 20 is connected to the dust collecting fan 12 and the hot air assembly 300 at the same time. At this time, the cleaning base station 100 can independently choose to perform self-cleaning or drying processing on any one of the dust box 410 and the cleaning member, and also enable the cleaning base station 100 to share one air duct member 20 in the dust collection mode and the drying mode, which can save the space occupied by the air duct member 20 in the cleaning base station 100, which is conducive to the miniaturization of the cleaning base station 100.

[0200] The structure of the third cleaning base station is further described below in conjunction with the accompanying drawings.

[0201] For the third type of cleaning base station, in the drying mode, except that the first connecting port 21 is connected to the fourth connecting port 24, and the second connecting port 22 is selectively connected to the fourth connecting port 24, the second connecting port 22 is not connected to the third connecting port 23, so as to avoid the hot air generated by the hot air component 300 flowing to the dust collecting fan 12 through the third connecting 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 of the cleaning parts in the drying mode.

[0202] See also Figure 1 and Figure 3The hot air assembly 300 includes a drying fan 310 and a heating element 320. The drying fan 310 is located outside the air duct member 20, and the drying fan 310 is configured to allow the external airflow of the air duct member 20 to enter the fourth connecting port 24. The heating element 320 is located on the air outlet side of the drying fan 310, and the heating element 320 is configured to heat the external airflow so that the external airflow forms a hot airflow. In this way, the hot air assembly 300 can convert the external airflow of the air duct member 20 into a hot airflow, and output the hot airflow to the fourth connecting port 24, thereby achieving a drying process for the dust box 410 and achieving a self-cleaning and drying process for the cleaning member.

[0203] See also Fig.11 and Fig.12 The air duct switching member 50 is movably disposed in the air duct member 20 and is located between the second communication port 22 and the fourth communication port 24. For example, the air duct switching member 50 is movably disposed 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 fourth communication port 24 when it moves in the air duct member 20.

[0204] In this way, through the movement of the air duct switching component 50 in the air duct component 20, the connection state between the second connecting port 22 and the fourth connecting port 24 can be controlled, so that when the cleaning component needs to be self-cleaned and dried in the drying mode, the second connecting port 22 and the fourth connecting port 24 can be connected through the movable air duct switching component 50, so that the hot air flow flows to the cleaning component.

[0205] Furthermore, since the air duct switching component 50 is located between the second connecting port 22 and the fourth connecting port 24, when the air duct switching component 50 moves to connect the second connecting port 22 with the fourth connecting port 24, the second connecting port 22 is opposite to the fourth connecting port 24, so that most of the hot air flow output from the fourth connecting port 24 will flow to the cleaning component through the second connecting port 22, so as to improve the drying effect of the cleaning component.

[0206] In the drying mode, if only the dust box 410 needs to be dried, the second connecting port 22 can be disconnected from the fourth connecting port 24 through the movable air duct switching member 50 , so that the hot air flows into the dust box 410 .

[0207] It should be noted that, considering that it takes a long time to dry the cleaning parts, when the cleaning parts are dried in the drying mode (i.e., the second connecting port 22 is connected to the fourth connecting port 24), the fourth connecting port 24 is connected to the first connecting port 21. Therefore, when drying the cleaning parts, a small amount of hot air flow passes through to dry the dust box 410. Based on actual considerations, there is no restriction on whether to dry the dust box 410 first or the cleaning parts first.

[0208] The activity of the air duct switching member 50 in the second sub-air duct 26 includes the rotation mentioned above. When the air duct switching member 50 is rotated to the open position, the second communication port 22 is connected with the fourth communication port 24. Correspondingly, when the air duct switching member 50 is rotated to the closed position, the second communication port 22 is not connected with the fourth communication port 24.

[0209] See also 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 member 20, and the projection of the fourth communication port 24 on the opposite side of the air duct member 20 has an overlapping area with the second communication port 22. In other words, the projection of the fourth communication port 24 on the side where the second communication port 22 is arranged on the air duct member 20 has an overlapping area with the second communication port 22. In this way, when the cleaning base station 100 is provided with an air duct switching member 50 between the second communication port 22 and the fourth communication port 24 of the air duct member 20, it is convenient to selectively connect the second communication port 22 with the fourth communication port 24.

[0210] Since the fourth communication port 24 and the second communication port 22 are located on opposite sides of the air duct member 20, the fourth communication port 24 is also located on the air duct wall of the second sub-air duct 26 opposite to the second communication port 22. The formation method of the fourth communication port 24 is similar to the formation method of the second communication port 22, and the relevant description of the second communication port 22 can be referred to above, which will not be repeated here.
